Meanwhile, an arc guide bar is welded and fixedly connected to the outer side of each outer enveloping clamping plate I-15, a hole is provided at the corresponding position of the outer frame fixing plate 1-12, and a second spring I-26 is mounted on the arc guide bar.

    A pair of outer enveloping clamping plates I-15 is placed in a V-shaped, which ensures the stability of straight conveying of the seed potatoes, and also ensures certain pressure on the seed potatoes in a direction perpendicular to the flexible silicone conveying belts I-16 when the seed potatoes are in contact with the streamlined cutter 1-06, to increase the friction between the seed potatoes and the flexible silicone conveying belts I-16, so that the seed potatoes are reasonably stressed and can be pre-cut in half.
    As shown in Fig. 4, the streamlined cutter 1-06 is of a streamlined shape widened from top to bottom, the narrower upper end ensures that the cutter is sharp enough, and the lower end has a certain width to achieve adaptable separation of the seed potatoes after dicing.
    The seed potatoes cut in half and separated will enter the triangular separation device under the guidance of the cutter back and the further conveying of the conveying belts.
    As shown in Fig. 5, the triangular separation device comprises: two triangular conveying belts 1-21, two triangular guards 1-23, cylindrical roller drive shafts I-30 and an anti-rollover housing I-19. The two triangular conveying belts I-21 and the drive wheels respectively constitute a third conveying mechanism and a fourth conveying mechanism, and the third conveying mechanism and the fourth conveying mechanism are arranged in an inverted V shape and interfaced with the conveying faces of the V-shaped conveying space.
    The materials cut in half are conveyed by the third conveying mechanism and the fourth conveying mechanism respectively, and the cut surfaces of the materials are in contact with the conveying mechanisms.
    The triangular conveying belts I-21 are made of flexible silicone to ensure certain tension thereof, the cylindrical roller drive shafts 1-30 are connected by pins, the cylindrical roller drive shafts 1-30 penetrate through first thombic spherical bearing seats 1-24 and are connected with the triangular guards 1-23 by bolts 1-22, the triangular guards 1-23 are also fixedly connected to an outer frame of the machine by bolts, and the distance between the two triangular guards 1-23 matches with the cylindrical roller drive shafts I-30. In order to ensure equal distance, three equal-length polished shafts are added between the triangular guards 1-23 for limit check, and connected by screws 1-20 to contact the inner sides of the triangular guards
    1-23, to achieve equal distance everywhere between the triangular guards 1-23. The triangular guards 1-23 on the one hand ensure that the cylindrical roller drive shafts 1-30 will not move axially, and can prevent the half-cut seed potatoes from turning over on the other hand.
    The devices of above structure constitute an elastic self-positioning pre-dicing system, which can realize the half pre-cut function of the seed potato production process, and is safe, stable, efficient and highly reliable, and can realize self-positioning and self-adaption to the shape and size of seed potatoes by means of V-shaped positioning at three places and elastic holding of the springs.
    As shown in Fig. 1, the drive system of the elastic self-positioning pre-dicing system adopts belt drive to drive the V-roller drive shafts I-17 to rotate, the elastic V-shaped self-positioning device conveys power between the two power drive shafts 1-28 by means of drive of the first drive steering gear 1-01, to realize synchronous movement of the two flexible silicone conveying belts I-16 placed vertically, and then the cylindrical roller drive shafts I-30 of the triangular separation device are controlled again by the belt drive to have a rotation speed slightly higher than the movement speed of the flexible silicone conveying belts I-16 placed vertically, thereby facilitating the separation of the half-cut seed potatoes.
    The flexible silicone conveying belts I-16 in the elastic V-shaped self-positioning device are required to run stably, thereby providing a stable dicing environment for the seed potatoes. The belt drive has the advantages of stability, buffering, shock absorption, simple structure and low cost, so the belt drive is used as the drive system of the elastic V-shaped self-positioning device. The flexible silicone conveying belts I-16 in the elastic V-shaped self-positioning device are ensured to have the same speed in opposite directions, that is, the two power drive shafts are required to rotate synchronously in opposite directions. The first drive steering gear 1-01 is used for drive, so the drive ratio is accurate and stable, the operational reliability is high, and the service life is long. For the drive of the conveying belts in the triangular separation device, considering that the triangular separation device has a small size and a compact structure and the production speed needs to be adjusted according to the actual production situation, it is more in line with the actual situation to control the speed of the triangular separation device by the belt drive. After experimental test, the design of the above drive system can achieve the desired effect, so the selection is correct and the design requirements are met.
    Feasibility analysis of the elastic self-positioning pre-dicing system and selection of springs In order to realize the self-adaptation of the elastic V-shaped positioning device to the shape of seed potatoes, and to ensure good stability when the seed potatoes are in contact with the streamlined cutter I-06, three groups of first springs 1-18 are mounted on the guide bars of rotating shafts of the middle three pairs of V-rollers 1-17, and a group of second springs I-26 is also connected between the outer enveloping clamping plates I-15 and the outer frame fixing plate 1-12. According to force analysis and actual requirements, these four groups of springs are all cylindrical helical springs. During the straight conveying process of the elastic V-shaped positioning device, the position status of seed potatoes is shown in Fig. 6.
    The cylindrical helical springs have a linear characteristic curve, are stable in rigidity, simple in structure, convenient to manufacture and wide in application, and are mostly used in mechanical equipment for buffering, shock absorption, energy storage and movement control, and their characteristic curve is shown in Fig. 7.
    The diameters of the guide bars where the cylindrical helical springs are located are 8 mm, and the diameter of the spring material is 13 mm, which satisfies <13 mm, so the spring material is of carbon spring steel wire class C. The compression springs with large height-diameter ratios b are bent laterally and loses the stability when the axial loads reach certain values. In order to ensure stable use, the height-diameter ratio b=Hy/D should meet the following requirements: When the height-diameter ratio b does not meet the actual requirements, it can be calculated according to the following formula: P.=CyxPxH, > P, 0 In the formula, P——critical load of a spring I-18, N; Cg—Instability coefficient, which is looked up from the mechanical design manual; P’——Stiffness of the spring 1-18, N/mm; P, Maximum working load, N. A range of the height-to-diameter ratio b can be determined by the calculation with the formula, and then the height Ho of the spring I-18 is determined. Therefore, the stability of the cylindrical helical compression springs is guaranteed. Analysis and calculation of friction of flexible silicone conveying belts The seed potatoes are in contact with the flexible silicone conveying belts during the straight conveying process, and the friction generated by the flexible silicone conveying belts drives the seed potatoes to move to the streamlined cutter for further contact with the cutter to overcome the impact of the cutter on the seed potatoes, thereby realizing the half cut process of the seed potatoes. After the half cut is completed, the seed potatoes are conveyed by the triangular separation device, the conveying belts here are still the flexible silicone conveying belts I-16, and the large friction of the conveying belts prevent the half-cut seed potatoes from deviating and rolling over. The stress analysis of seed potatoes in the upright state 1s shown in Fig.
    8. When the seed potatoes are in contact with the streamlined cutter [-06, the seed potatoes will receive a vertical upward support force. To convey the seed potatoes by the flexible silicone conveying belts I-16 to complete the half cut process, the following formula must be satisfied: G+ 2x Ph xcosa > 2x Fgpxcosa+ F, (2) In the formula, G——Gravity of a seed potato itself, N; F‚ Friction subjected by the seed potato in the upright state during the straight conveying process, where F=Fp, N;
    il Fr—Resultant force simplified from spring force subjected by the seed potato, in the direction perpendicular to the conveying belts, N; Fx Support force of the streamlined cutter 1-06 for the seed potato, N; a Angle between the outer enveloping clamping plate I-15 and the horizontal plane, °; The friction of the flexible silicone conveying belts will be analyzed in detail below.
    Looked up from the mechanical design manual, the sliding friction coefficient is 0.48 under dry friction between rubbers (parallel textures). Silicone is a kind of rubber.
    The potato skin is regarded as a rubber with parallel textures, and is in a critical state of sliding generation during the conveying process of the flexible silicone conveying belts, which can be regarded as a sliding friction for further analysis on this basis.
    The formula for calculating the friction subjected by the potato can be expressed as: Fz ky, 3) In the formula, u — friction coefficient, which is 0.48 looked up from the mechanical design manual; Fy Support force subjected by the seed potato in the upright state during the straight conveying process, N, that is: Fi =3xP xsina @ The value of a ranges from 70° to 80° by calculation according to the design requirements, the spring has a diameter of d and a length of Ho, and the value of P: can be calculated according to formula (1). P =C,xP'xH, 6 In the formula, P- Critical load of a spring, N; Cg—Instability coefficient, which is looked up from the mechanical design manual; P ’——Stiffness of the spring, N/mm; The parameters are brought into formula (2) and arranged to obtain:
    G+6xuxCy x PxHxsinaxcost >2xC, x PxH, xcosa+ EF © us 2xCyx Px Hyxcosa+ 1, CG 6x, x P'x Hy xsin dx cosa 7) Whether u=0.48 satisfies the formula 1s verified.
    After u=0.48 is introduced, it meets the design requirements.
    That is, the flexible silicone conveying belts are appropriate and meet the friction requirements.
    Embodiment 2 In some embodiments, an elastic self-positioning pre-dicing method is disclosed, comprising the following process:
    A tapered self-positioning limit feeding system (that is, a previous station) feeds seed potatoes into the elastic self-positioning pre-dicing system orderly, the long axis of the seed potatoes is in the vertical direction at this time, the seed potatoes fall into the entrance of the V-shaped space of the elastic V-shaped self-positioning device, the drive shafts 1-28 rotate to drive the flexible silicone conveying belts I-16 to move under the enveloping of the V-shaped profile of the flexible silicone conveying belts I-16, the seed potatoes are further conveyed straightly, and the three pairs of V-rollers 1-17 at the middle position adapt to the shape and size of the seed potatoes under the elasticity of the first springs I-18 to ensure the stability and reliability of the straight conveying process.
    The potato seeds are further conveyed vertically downward, the outer enveloping clamping plates I-15 adapt to the shape and size of the seed potatoes again, the outer enveloping clamping plates I-15 undergo position change of certain angle about the drive shafts under the action of the arc guide rails and the elasticity of the second springs I-26 to adapt to the shape and size of the seed potatoes, and the flexible silicone conveying belts I-16 herein have stronger enveloping property on the seed potatoes under the elasticity of the first springs I-18, so that the seed potatoes are in stable contact with the streamlined cutter I-06 to implement the half cut process.
    Further, the seed potatoes are in contact with the cutting edge of the streamlined cutter [-06. Under the combined action of V-shaped positioning, elastic clamping and flexible conveying, the subjected friction and the gravity of the seed potatoes are greater than the impact of the streamlined cutter I-06 on the seed potatoes, which can realize the stable half cut of the seed potatoes.
    With the streamlined shape widened from top to bottom, the half-cut seed potatoes are separated adaptively and enter the flexible silicone conveying belts 1-16 of the triangular conveying device.
    The flexible silicone conveying belts I-16 of the triangular separation device have large friction, which ensures that the seed potatoes will not deviate, roll over or the like before entering the designated station.
    After being conveyed by the triangular separation device, the half-cut seed potatoes are finally conveyed to the center of a conveying tray of an intelligent dicing station (that is, next station) for intelligent identification and detection of the dices.

    It should be understood by those skilled in the art that various modifications or variations could be made by those skilled in the art based on the technical solution of the present invention without any creative effort, and these modifications or variations shall fall into the protection scope of the present invention.
