    The invention relates to the processing of polymeric materials and can be used for granulating scientific research institutes of rods extruded from munts in the form of a liquid melt. gutters, including the container, connected and inclined chute, feeding the harnesses in the cutting node Cl 1. In this device, the carrying surface of the inclined chute is located: the same plane Connecting the outputs of the mouthpiece and the entrance to rezhuvschy node. With such an arrangement of the chute, the operation of the cutting unit must be carefully matched to the speed of feeding of the harnesses, because as the speed of rotation of the cutting knot increases, the harnesses will be pulled and raised from the top of the bone of the chute, i.e. extracted from the cooling water, which reduces the efficiency of the cooling water and after. Additionally, the quality of the granules. TGMs are also responsible for lowering the quality of the pellets; the device does not provide for the removal of plastic straps from the drain chute at the moment the device starts, when the molten plastic contains contaminants or has acquired a final uniform composition. The closest in technical essence and the achieved result to the invention is a device for feeding cords of molten plastic to an inclined discharge chute, containing a gripping and turning element for providing free passage of the harnesses in the off position behind the chute and outside the gripping element, the upper end of which is in the working position placed behind the free fall line of the harnes coming out of the mouthpieces, the device for supplying water to the upper end of the discharge chute and the axis of rotation located in a known device, a drainage bar in the zone of its upper part passes into a rotary shield - a gripping element of the harnesses, which is mounted on the turning axis passing across the cnycKHOf chute, located at the upper end of the shield, so that , the flap can take two positions: working, in which the flap side opposite to the axis passes into the chute, forming a unified structure with respect to the passage of the harnesses and cooling water, in which the flap is part of the chute, while the flap is rehvatyvaet exiting the mouthpieces and tows together with cooling water supplies it to the chute and outside, wherein the plate is rotated because of the chute that exiting the mouthpieces harnesses fed between the flap and the chute. In this process, there is a need, before starting the processing of plastic bundles for this purpose through the gutter, to the granulator, to remove the first material coming out of the mouthpieces, since it usually contains soils or has not yet acquired its final uniform composition. At the same time, the harnesses pass along a relatively narrow Mine between the shield and the rear side of the chute, which, due to the specified spatial relationships, is subject to-. It is contaminated by diverging wiring harnesses. Cleaning the corresponding places is difficult due to the fact that the current, together with the rear side of the chute, forms a shaft, which is relatively difficult to access. All this complicates the maintenance of the device due to its laboriousness and the need for considerable time. cleaning his items. The purpose of the invention is to simplify the maintenance of the device by preventing its element from becoming contaminated and reducing the time for cleaning them. This goal is achieved by the fact that in a device for supplying molten plastic harnesses to an inclined discharge chute containing a harness gripping element and turning for the vehicle, the free passage of the harness in the inoperative position behind the chute and outside the gripping element, the upper end of which is located in the working position behind the free fall line coming out of the mouthpieces of the harnesses, a device for supplying water to the upper end of the gutter and the axis of rotation, located transversely to the gutter, the gutter mount van placed at a distance from its upper end the pivot axis movable upper end of the gripping element through the wiring in the inoperative position, wherein the free-fall harness line time behind meschena gripping element. The axis of rotation is located at the lower end of the chute. The pivot axis is located in the middle of the chute. The axis of rotation is located in the lower part of the upper third of the chute. The gripping element is provided with a tearing element located at its upper end to cut the bundles when moving the gripping element. The tearing element is made in the de rod placed transversely to the surface of the gripping element and protruding beyond the upper end of the gripping element in order to pick up the bundles and remove their NIN at a distance from the gripping element. The tearing element is designed in the form of a knife for blocking the harnesses during its movement. With the indicated device arrangement, the rear side of the chute, both in the working and non-working position, remains perfectly accessible, since the described structure does not form a shaft. In this case, the harnesses falling behind the chute and behind the grip element tend to adhere, therefore the risk of contamination is eliminated. However, the contamination on the gripping element or on the rest of the chute would not have a great value, since they would always form on the back side of the corresponding part, which in normal mode the strands did not pass through, while in the known device there is a contamination on the front side of the working elements, which in the working position should intercept the harnesses and feed them to the chute. Depending on the length of the gutter, the axis of the turn can be placed in various places on the gutter. 4 If the chute is relatively short, it is advisable to position the axis of rotation at the lower end of the chute. In this case, therefore, the entire chute is turned. With a long chute, the axis of rotation is located in the center or in the upper third of the gutter. In these cases, only that part of the chute that is above the axis of rotation is rotated. The degree of rotation is determined by the desired accessibility of the mouthpiece area. The greater the turn of the chute or its corresponding part, the more accessible the mouthpieces. Since the erd chute grip element rotates the upper part through the harnesses, it is possible to attach a tearing element to its upper end, which, when this end moves, cuts them through the harnesses. In this case, when the gripping element of the drain chute is rotated from the non-operating position, in which the harnesses pass behind the drain chute, the strands located above the incision site are automatically fed to the chute without working with the mouthpieces. The breaking element can be made in the form of a rod extending across the harnesses, which is located at some distance from the end of the gripping element passing through the harnesses and mounted on it. When this end moves, the rod picks up the harnesses and keeps them at a distance from the gripping element. At first, the harnesses hang on the rod crossing them, but then under the force of gravity fall from the rod, as the rod spatially separated from the upper end of the gripping element does not cool, resulting in the harnesses on the rod remaining in the molten state. In this state, the harnesses may fall from the rod behind the chute. You can also disrupt the element in the form of a knife, which. when moving slides on mouthpieces. In this case, the cutting of the harnesses occurs directly under the mouthpieces, therefore, the material coming out of the mouthpieces after cutting the harnesses falls on the gripping element that has turned after cutting the harnesses into the working position, and from there it goes to the chute. Fig. 1 schematically shows a device with an axis of rotation at the lower end of the chute (the chute is in an inoperative position) i in Fig. 2 - the same, with the chute in the working position; fig. 3 - the same, with the axis of rotation in the center of the drain chute (the inoperative position located above the axis of rotation of the gripping element is shown by dash-dotted lines), and figure 4 is a device with an axis of rotation in the upper third of the chute; in fig. 5-8 shows a device with a rod located at the upper end of the grip element of the chute, in four operating positions in FIG. 9-12 - a device with a knife located at the upper end of the grip element. The device shown in Fig. 1 comprises a drain chute 1, in the lower end of which, a pivot axis is installed at a distance from its upper end. At the upper end of the chute 1, an element 3 is gripped and rotated to ensure free passage of the harnesses in an inactive position behind the chute 1 and outside the grip element 3; that (according to the embodiment of FIG. 1 is integral with the same front forehead 1 ). The chute 1 is mounted on the axis of rotation 2 with the possibility of moving the upper end of the element. These 3 grips through the harnesses to the non-working position, in which the free fall line of the harnesses is located behind the gripper element 3. On the gripping element 3, there is a device for supplying water, made in the form of a tank 4 with an overflow device 5- In the tank 4 Cooling water is supplied through the connecting nozzle 6 and the supply pipe line 7. A few spray nozzles 8 are disposed in front of the discharge chute 1, to which coolant water is supplied through pipe 9. The nozzles 8 are directed to the drainage channel 1 and spray it with cooling water. In the non-operating position of the discharge chute 1 shown in Fig. 1 and above it there is a block 10 46 of the mouthpieces 11, of which the exit plastic strands in molten state. In this state, the plastic harness runs vertically downwards and into the container 12. Under the discharge chute 1 there is a granulator 13, consisting of two feed rolls 14 and 15 and a milling cutter 16, which interacts with the knife 17. In granulator 13 through the nozzle 18 cooling water is supplied, which rises in chamber 19 and flows through nozzle 20 to bottom 21, enveloping mill 16. Here the water supplied in this way falls on the granulate cut by the mill 16, which is then pulled out of the granulator 13 in the direction shown by the arrow. In the working position of the device (Fig. 2), the harnesses 22 leaving the block 10 of the mouthpieces 11 first fall in the direction shown by the dash-and-dot line 23, down until they are received by the gripping element 3 and directed to the chute 1. Then The harnesses 22 fall into the zone of the falling rolls 14 and 15 and are cut by milling cutter 16 into pellets. At an appropriate speed of the feed rolls 14 and 15, the harnesses tighten tightly along the chute 1. In the non-working position shown in Fig. 1, the harnesses 22 can fall vertically into the tank 12, mine the chute 1 and the gripping element 3, forming an integral part of the chute 1. This position is established at the start-up of the device, when synthetic material leaves the block 10 of the mouthpieces 11, which often does not yet have the required quality. Such a material cannot be mixed with a granulate of a valuable material. The zone of the unit 10 of the mouthpieces 11 is free, and there is no danger of contamination of the discharge chute 1. As soon as a full-fledged material begins to emerge from the block 10 of the mouthpieces 11, the discharge chute 1 with the gripping element 3 rotates on the axis 2 of rotation in the direction opposite to the arrow 24 (figure 1) and is in the working position shown in figure 2, in which as already mentioned, 10 mouthpieces coming out of the block
    11 harnesses 22 are adopted by element 3.; capture and then processed into granules in a known manner.
    The movement of the chute 1 with the gripping element 3 in both directions occurs through the harnesses 22, the flow of which is continuous. To prevent the molten strands 22 from sticking to the upper end of the gripping element, the flow of the strands 22 is interrupted in a known manner for a short time using a valve (not shown) on the block 10 of the mouthpieces 11.
    Thus, the withdrawal of synthetic material with insufficient quality is very easy due to the fact that synthetic material passes by the discharge chute.
    IC element 3 capture, i.e. from the back of the chute 1. Therefore, the synthetic material retracted, i.e. The harnesses 22 are well observable. If it is determined that from the highlight 10 mouthpieces
    I1 is a qualitatively flawless material, then the chute 1c with the gripping element 3 is turned in such a way
    that it becomes in the way of the harnesses 22, for which the flow of synthetic material is briefly stopped. When the synthetic material begins to exit the mouthpieces 11, on the way of the harnesses 22 under the block 10 of the mouthpieces 11 there is a gripping element 3 which guides the harnesses 22 to the chute 1 and to the granulator I.
    In the modification of the device in FIG. 3, only a part is rotated. chute 1, i.e. its upper section 25 with a gripping element 3, while for turning the upper section 25 with a gripping element 3, an axis of rotation 26 is provided, which is located in the middle of the drain chute 1.
    Fig. 3 shows both the operating and non-operating positions of the devices, generally similar to those shown in Figs. 1 and 2, with the non-operating position of the upper section 25 shown by dash-dotted lines.
    In the embodiment of the device according to FIG. 4, the axis 27 of the rotation of a part of the discharge chute 1 is located even higher than the device of FIG. In this case, only one axis is higher than axis 27.
    the gripping element 3, which can occupy a position similar to that shown in FIG. 3 by dash-dotted lines (not shown in FIG. 4).
    The device according to FIGS. 5-8 is similar to that shown in FIG. 4, but the turning element 3 of the gripper is provided at its upper end with a tearing element in the form of a rod 28, which is located across the harnesses 22 or 29 and parallel to the row of the mouthpieces 11 in block 1 The rod 28 is installed at some distance from the end of the gripping element 3 passing through the harnesses 11, therefore it is not cooled by water supplied to the container 4. Thanks to the rod 28 acting as a tearing element, it is possible to rotate the gripping element 3 without interrupting the flow of the synthetic mat Series from the block 10 mouthpieces 11
    When the device is in an inactive position, the gripping member 3 is rotated from the tow 22, and the tow 22 consists of poor-quality material and is directed to the container 12 (FIG. 3).
    If from the block 10 of the mouthpieces 11 there is a material of adequate quality, the gripping element 3 is rotated through the strands 22, i.e. in the position shown in Fig.6. In this case, the harnesses 22 leaving the block 10 of the mouthpieces 11 are first hung on the rod 28 and fall down on both sides of the rod 28, as shown in FIG. Since the rod 28 is not cooled, the harnesses 22 on the rod 28 remain in the molten state and finally break through under the force of gravity. The position shown in Fig. 8 arises, in which the harnesses 29 of the block 10 of the mouthpieces 11 are picked up by the gripping element 3 and directed to the part (not shown) of the groove 1, which is represented in Fig. 4.
    Such a design allows switching, i.e. rotation from the inoperative position (Fig. 3) to the operational one (Figures 6-8), without interrupting the flow of the harnesses 22. In this case, using the rod 28 acting as the breaking element, the flow of the harnes 22 is automatically switched by rotating the gripping elements 3. To prevent even slow curing of residual material adhering to the rods 28, the rod 28 is heated to approximately the melting point of the processed material; for example, by electric heating.,. The functions of the embodiment of the device of FIG. 9 and 10, where only the gripping element 3 is presented, similar to the embodiment of the device of FIG. 4. In the device shown in Fig. 9, it is foreseen that x; x 30, which, when the gripping element 3 is moved from the inoperative position (Fig. 9) to pa. The barrel slotting (FIG. 10) slides along the surface 31 of the block 32 of the mouthpieces. For this, surface 31 is slightly convex. The knife 30 is attached to the bracket 33 by means of an axis 34 f on which the lever 35 is located, at one end of which a knife 30 is located. To the other end of the lever 35 a spring 36 is attached, also connected to the bracket 33. Under the action of the spring 36, the lever 35 tends to turn clockwise. However, this is prevented by the knife 30, which extends to the surface 31. With the initial non-working position (FIG. 9), the harnesses 22 pass vertically from the mouthpiece block 32 and fall into the container 12. If the gripper element 3 is turned to the working position shown in FIG. . 10, the bracket 33 with the lever 35 and the knife 30 moves along the surface 31 of the block 3 of the mouthpieces, while the knife 30 slides over the surface 31 and simultaneously bridges all the mouthpieces located one behind the other in block 32. At the same time the knife 30 cuts the cords 22, whereby the flow of the harnesses 22 is interrupted. The gripping element 3 is in such a position that the harnesses 22 (FIG. 10) coming out after the break now fall on the gripping element 3, which is in the working position. Then the gripping element 3 directs the harnesses 22 in the manner shown in FIG. Below the chute 1 and into the granulator 13. Each end of the knife 30 rests on its bracket 35, so that between both brackets (only the front bracket is shown in Fig. 10) there is a free space through which the harnesses 22 can pass. Thus, the brackets 35 do not interfere with the passage Gutov 22. Figure 11 and 12 shows a device corresponding to the device of FIG. 9 and 10, but the lever 35 is replaced by a spring-loaded telescope 37. The proposed design of the device provides free running of the harnesses behind the gripping element and the chute in the off position, which reduces the possibility of contamination of the device, reduces the time to clean it and, therefore, simplifies the maintenance of the device.
