![]() Device for coating steel pipes with thermoplastic material
专利摘要:
A pipe jacketing and wrapping station includes a pressure roll, urging an extruded ribbon onto axially passing, rotating pipes, arriving in end-to-end abutment. Feelers determine level differences of the pipes adjacent to the pressure roll and cause the end of the trailing pipe to be lowered or lifted as required. 公开号:SU888807A3 申请号:SU792860204 申请日:1979-12-28 公开日:1981-12-07 发明作者:Кеммерлинг Карл-Хайнц 申请人:Маннесманн Аг (Инофирма); IPC主号:
专利说明:
one The invention relates to equipment for coating steel pipes with a thermoplastic plastic, for example a polyethylene film, by a spiral winding method. A device for coating pipes, including a roller table along the pipes, a means of coating and means Q for selecting the finished pipe 1, is known. The known device is intended for coating pipes by irrigation. Closest to the proposed device for coating steel pipes with thermoplastic plastic extruded in the form of a tape by winding it in a spiral, including an extruder located along the axis of the pipes forming a roller table a number of roller supports for transporting them and a pressure roller whose length is greater than the width of the winding tape 2 . In the known device, successively transportable pipes are supplied with a gap of 250-300 mm, which, with continuous tape winding, results in excessive consumption of polymeric material in the area of the gap between the pipes. thirty The purpose of the invention is to reduce the loss of plastic. The goal is achieved by the fact that a device including an extruder located along the axis of the tubes forming a roller table of a series of roller supports for their transportation and a pressure roller longer than the width of the tape to be reeled is provided arranged sequentially in the area where the tape is rolled, displaced relative to each other in the direction of the axis pipes joined together by two ends with two probe rollers fixing the difference in height between the beats of steel pipes and interacting with a regulating device related to the role oic support under the front end coming to the winding tube, mounted with the possibility of varying the position in height on the cylinder rod. FIG. 1 shows a device, front view, FIG. 2 - the same, side view.

Claims (2) [1] The device for coating steel pipes with thermoplastic plastic consists of an extruder 1, a pressure roller 2, roller probes 3 and 4, and supports. 5 and 6 of the pipe 7, the bearing 6 being commented on the rod of the cylinder 8. The operation of the device is carried out as follows. The tube 7 is fed on supports 5 and 6 of the roller table to the winding zone. The tape 9 from the extruder 1 is laid down on 7 and rolled by a pressure roller 2, the length of which is longer than the width of the tape 9. To achieve a high-quality winding of the pipe ends, it is necessary that the pressure roller 2 adjoin to both pipes simultaneously. in the place of their docking. In this case, the roller probe 3 is in contact with the generatrix of the already wound pipe 10, and the roller probe 4 - with the unrefined pipe 7. If between pipes 7 and. 10, as a result of the beating, there will be a difference in height, then the movement of the roller probe 3 via a regulating device (not shown in the drawing) transmits a command to the cylinder 8, the stem of which respectively raises or lowers the support 6 so that the pipes 7 and 10 lie along the same axis. Since the probe rollers 3 and 4 constantly compare the height of the pipes to each other, the pressure roller 2 is constantly attached to both pipes 7 and 10 and presses the film 9 on them. When carrying out the invention, the steel pipes on the winding come end-to-end to the other, as a result of which winding is performed without a gap between the pipes, eliminating the extra consumption of polymeric material. Apparatus of the Invention A device for coating steel pipes with a thermoplastic plastic extruded in the form of a tape by winding in a spiral, including an extruder located along the axis of the pipes forming a roller table of a series of roller supports for transporting them and a pressing roller whose length is greater than the width of the winding tape, characterized by that, in order to reduce the loss of plastic, it is provided with successively located in the area of the stitching of the tape displaced relative to each other in the direction of the axis of the pipes joined between second ends, two rolikamischupami, fixing the difference in height of the beat and vzaimodeystvukadimi steel pipes with a regulating device associated with the roller support for the front end of the incoming to the winding tube, mounted with the possibility of varying the position in height on the cylinder rod.
