DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0020] Please refer to Figures 1-9 , the present application provides a technical solution: As Figures 1-4 shown, in the present device, the rack 1 serves as the basic support structure of the device, providing a mounting carrier for each functional component. On the rack 1, the feeding roller 2, the receiving roller 3 and a plurality of guide rollers 4 are arranged in rotational connection through bearings. The feeding roller 2 is used to store the skin raw material to be cut, the receiving roller 3 is responsible for winding the excess material after cutting is completed, and the guide rollers 4 adjust the direction of the skin during the conveying process to ensure stable transmission.

[0021] One end of the receiving roller 3 and the guide roller 4 is fixedly installed with the driven pulley 7 by key connection or interference fit. At the corresponding position of the rack 1, the driving motor 8 is installed by bolt fastening. When the driving motor 8 works, the output shaft rotates, and the driving pulley 9 fixedly connected by the key rotates synchronously. The driving pulley 9 and the driven pulley 7 are wound with the belt 10 to form a belt transmission system. When the driving motor 8 operates, the power is transmitted to the driven pulley 7 through the driving pulley 9 and the belt 10, which in turn drives the receiving roller 3 and the guide roller 4 to rotate, realizing the conveying and winding action of the skin in the device. It should be noted that the driving pulley 9 and the driven pulley 7 rotate in the same way.

[0022] In addition, on the frame 1, also through the bearing to realize the rotation support, arrangement cleaning shaft 11. The surface of cleaning shaft 11, through the conventional assembly mode such as bonding, install several soft material cleaning brush 12 (such as rubber strip, cloth strip, etc.). At the same time, on the output shaft of driving motor 8, in the form of key connection, fix the gear 14;The end of cleaning shaft 11, also through the key connection, fix the pinion 13, the gear teeth of gear 14 and pinion 13 are engaged with each other, form gear pair. In this way, when driving motor 8 operates, in addition to driving material collecting roller 3, guide roller 4, can also drive cleaning shaft 11 to rotate through the meshing transmission of gear 14 and pinion 13, provide power for subsequent cleaning action.

[0023] Cutting assembly 5: As shown in Figure 5 Cutting assembly 5 is assembled on frame 1 by bolt fastening, accurately completes the skin cutting, the connection and principle of each part are as follows: Support frame 51 is the basic support of cutting assembly 5, which is rigidly connected with frame 1 by bolts. On the surface of support frame 51, several guide sleeves 52 are fixed by bolts, which are arranged in vertical direction and have sliding channels adapted to guide columns 53 inside. The guide column 53 penetrates into the guide sleeve 52 in sliding fit, and the lower end is welded or bolted with the mounting bracket 54. When the guide column 53 slides along the axis direction (vertical direction) of the guide sleeve 52, the mounting bracket 54 can follow the stable lifting to provide accurate cutting guide for the cutter die 55, avoiding deviation during cutting.

[0024] The mounting bracket 54 is a bearing part of the cutter die 55, which is assembled with the cutter die 55 by bolt connection, slot clamping and other detachable ways (such as T-shaped slot, quick release bolt). It is convenient to replace different cutter dies 55 according to the specifications of the skin. On the top of the support frame 51, the cutting telescopic cylinder 57 is fixed by bolts, and the movable end (piston rod) of the cutting telescopic cylinder 57 is directly connected with the mounting bracket 54 (welded or bolted). When the cutting telescopic cylinder 57 moves, the piston rod extends and retracts, driving the mounting bracket 54 and the cutter die 55 to rise and fall along the guide path formed by the guide column 53 and the guide sleeve 52, realizing the downward cutting and upward resetting of the cutter die 55.

[0025] On the bottom surface of the mounting frame 54, several guide seats 561 are fixed by bolts, and sliding holes are processed in the guide seats 561. The limit guide rods 562 are inserted into the sliding holes in a clearance fit manner and can slide freely in the vertical direction. The lower end of the limit guide rod 562 is welded or bolted to the pressing plate 563. The spring 564 is sleeved on the rod body, one end of the spring 564 abuts against the pressing plate 563, and the other end abuts against the guide seat 561, forming an elastic pre-tightening structure. The lower surface of the pressing plate 563 is fixed with an elastic pad 565 (such as a rubber pad) by an adhesive process, and the distance from the elastic pad 565 to the cutting platform 67 is less than the distance from the die 55 to the cutting platform 67.

[0026] When the driving motor 8 is intermittently stopped in the step mode (the skin is transported to the position), the cutting telescopic cylinder 57 is vented to extend, pushing the mounting frame 54 and the die 55 to descend synchronously. Because the distance between the elastic pad 565 and the cutting platform 67 is smaller, the elastic pad 565 will contact and adhere to the skin material first; the cutting telescopic cylinder 57 continues to apply pressure, the spring 564 is compressed to produce elastic deformation, and the pressing plate 563 continuously presses the skin, ensuring that the skin does not shift during cutting; when the die 55 descends to contact the skin with the mounting frame 54, the cutting action is completed by the blade of the die 55; then the cutting telescopic cylinder 57 is reset, the spring 564 is elastically released, the pressing plate 563 and the limit guide rod 562 are pushed to rise, and the next cutting cycle is waited.

[0027] The overturning assembly 6: As shown in Figures 5-9 , the overturning assembly 6 is fixed on the rack 1 in a bolted manner, and the descending, overturning and resetting actions of the cutting platform 67 are realized by mechanical transmission to complete the unloading of the cut skin. The specific structure and principle are as follows: The support plate 61 is a basic support member of the overturning assembly 6 and is firmly connected to the rack 1 by bolts. On the surface of the support plate 61, a slide rail perpendicular to the skin conveying direction is arranged. The lifting plate 62 is matched with the slide rail through a sliding block (the sliding block is embedded in the slide rail and can slide along the length direction of the slide rail), so that the lifting plate 62 can slide smoothly along the vertical direction of the support plate 61 (the extension direction of the slide rail).

[0028] On one side of the support plate 61, the overturning telescopic cylinder 68 is fixed by bolts. The movable end (piston rod) of the overturning telescopic cylinder 68 is connected to the lifting plate 62 in a bolted or welded manner. When the overturning telescopic cylinder 68 moves, the telescopic movement of the piston rod can directly drive the lifting plate 62 to rise or descend along the slide rail, providing power in the vertical direction for the overturning action of the cutting platform 67.

[0029] On the lifting plate 62, a rotating support is achieved through a bearing, and a turnover shaft 63 (the axis of the turnover shaft 63 is perpendicular to the sliding direction of the lifting plate 62) is installed. One end of the turnover shaft 63 is fixed to a turnover crank 64 (the turnover crank 64 is a rigid rod structure) through a key connection. The end of the turnover crank 64 away from the turnover shaft 63 is installed with a guide wheel 65 through a bearing, and the guide wheel 65 can freely rotate around its own axis.

[0030] On the surface of the support plate 61, a broken-line guide groove 66 (the groove cross section matches the profile of the guide wheel 65) is processed to match the guide wheel 65. The guide wheel 65 is embedded in the guide groove 66, and its movement trajectory is constrained by the shape of the guide groove 66. The cutting platform 67 is fixed on the side of the turnover shaft 63 away from the turnover crank 64 through bolts and rotates synchronously with the turnover shaft 63.

[0031] When the skin cutting is completed, the turnover telescopic cylinder 68 is retracted, and the piston rod pulls the lifting plate 62 to slide downward along the slide rail of the support plate 61. In this process, the guide wheel 65 at the end of the turnover crank 64 descends synchronously with the lifting plate 62. Because the guide wheel 65 is limited by the broken-line path of the guide groove 66, the turnover crank 64 will rotate around the axis of the turnover shaft 63.

[0032] With the continuous descent of the lifting plate 62, the turnover shaft 63 and the cutting platform 67 first move downward in the vertical direction; when the guide wheel 65 enters the circular arc transition section of the guide groove 66, the rotation angle of the turnover crank 64 gradually increases, driving the turnover shaft 63 and the cutting platform 67 to complete a 90° turnover (if the broken-line shape of the guide groove 66 is adjusted, the turnover angle of the cutting platform 67 can be changed. The shape can be set by the designer according to the actual needs, which is not limited here). After the turnover is in place, the cut skin falls into the material collecting box 20 below the rack 1 due to its own gravity.

[0033] After the unloading is completed, the turnover telescopic cylinder 68 is extended, the piston rod pushes the lifting plate 62 to ascend upward along the slide rail, the guide wheel 65 moves reversely along the guide groove 66, the turnover crank 64 drives the turnover shaft 63 to rotate, and finally the cutting platform 67 is reset to the initial horizontal state, waiting for the next cutting operation.

[0034] In this embodiment, the cutting platform 67 is supported by two groups of turnover assemblies 6 to realize stable lifting of the cutting platform 67.

[0035] As Figures 4-5As shown, in the corresponding position of the rack 1, the tensioning support 15 is fixed by bolts, which is a rigid metal piece. The tensioning support 15 is rotatably supported by bearings, and the tensioning wheel 16 is installed thereon. The wheel body has a groove structure and is suitable for driving the belt 10. When the belt 10 is loosened due to long-term use, the position of the tensioning wheel 16 can be adjusted, such as the adjustment screw on the rotating support, to change the distance between the tensioning wheel 16 and the driving pulley 9 and the driven pulley 7, so as to re-tension the belt 10 and ensure that the power of the driving motor 8 is stably transmitted to the material collecting roller 3 and the guide roller 4, thereby maintaining the reliability of the belt transmission system.

[0036] As shown in the drawings, Figures 2-3 As shown, the material pressing rod 17 is rotatably installed on the rack 1 by bearings (the rod body is a rigid long strip), and the material pressing rod 17 can rotate slightly around the installation point. The connecting plate 18 is fixedly connected to the material pressing rod 17 by bolts, and the material pressing roller 19 is installed at the end of the connecting plate 18 by bearings. The roller body is made of rubber or polyurethane material and has a smooth surface. The material pressing roller 19 continuously contacts the surface of the skin during the skin conveying process by using its own gravity, and pre-presses the skin in the conveying process to avoid affecting the cutting accuracy due to shaking and deviation of the skin.

[0037] As shown in the drawings, Figure 3 As shown, the pressing roller 21 is rotatably installed above the guide roller 4 on the rack 1 by bearings. The pressing roller 21 cooperates with the lower guide roller 4 to further clamp the skin from the upper and lower sides of the skin, so as to ensure that the skin is in a flat and tight state before being conveyed to the cutting platform 67, thereby providing a stable material basis for the cutting operation.

[0038] As shown in the drawings, Figure 7 As shown, when the driving motor 8 is running, especially during the skin collecting stage, the overturning assembly 6 drives the cutting platform 67 to be in the overturning unloading position. The large gear 14 on the output shaft of the driving motor 8 rotates with the shaft, and the small gear 13 at one end of the cleaning shaft 11 is meshed with the large gear 14. The number of teeth of the small gear 13 is less than that of the large gear 14, forming a speed-up transmission, and the rotating speed of the small gear 13 is higher than that of the large gear 14, thereby driving the cleaning shaft 11 to rotate at a faster speed.

[0039] The cleaning brush 12 installed on the surface of the cleaning shaft 11 naturally falls due to its own gravity when the cleaning shaft 11 is stationary. When the cleaning shaft 11 rotates at a high speed, the cleaning brush 12 is scattered to the periphery under the action of centrifugal force and contacts the surface of the cutting platform 67. At this time, if there is residual skin on the cutting platform 67 due to static adsorption, oil stains and the like, the cleaning brush 12 can sweep the residual skin off to the lower collecting box 20 through contact and friction with the surface of the platform; at the same time, the cleaning brush 12 can also wipe and clean the stains on the surface of the cutting platform 67, so as to ensure the cleanliness of the cutting platform 67 and avoid affecting the subsequent cutting operation due to residual stains.

[0040] The transmission stability is maintained by the tensioning assembly, the skin conveying state is guaranteed by the pressing and compressing assembly 56, and the platform residues are cleaned by the cleaning assembly. The device can guarantee the operation stability and cutting quality in the whole process of skin conveying, cutting and unloading, and realize automatic continuous production.

[0041] A protective plate 58 is installed on the support frame 51 of the cutting assembly 5 through a hinge or a rotating shaft. One side edge of the protective plate 58 is in rotating cooperation with the support frame 51 and can freely flip around the rotating shaft, and the flipping angle is sufficient to cover or expose the cutting operation area.

[0042] Meanwhile, a support telescopic cylinder 59 is fixed on the side of the support frame 51 through a bolt, and the movable end of the support telescopic cylinder 59 is connected with the back of the protective plate 58 through a hinge.

[0043] When the device is in the cutting operation state, the support telescopic cylinder 59 is retracted, the protective plate 58 is pulled to flip downward around the rotating shaft until it covers above the cutting area, forming a physical barrier to prevent debris from splashing or personnel from touching the cutter die 55 during cutting, thereby playing a safety protection role.

[0044] When it is necessary to replace the cutter die 55 or clean the cutting area, the support telescopic cylinder 59 is extended, and the protective plate 58 is pushed to flip upward around the rotating shaft to expose the cutting assembly 5, thereby facilitating the maintenance work of the operator.

[0045] Working principle: during the use of the device, The driving motor 8 operates in a step intermittent mode, that is, it rotates for a certain angle and then pauses, and operates according to the set rhythm. The output shaft of the driving motor 8 drives the driving pulley 9 to rotate, and the power is transmitted to the driven pulley 7 at one end of the material collecting roller 3 and the guide roller 4 through the belt 10, so that the material collecting roller 3 and the guide roller 4 rotate synchronously. The skin raw material on the feeding roller 2 is pulled and sequentially passes through the guide roller 4, the compressing roller 21 and the corresponding guide roller 4 below to be clamped (to further flatten the skin), and the self-weight pre-pressing of the pressing roller 19 (to prevent deviation during conveying), and finally is conveyed to the specified position of the cutting platform 67. At this time, the driving motor 8 is paused, and the skin is in a static state waiting for cutting.

[0046] After the driving motor 8 stops, the cutting telescopic cylinder 57 extends to push the mounting frame 54 to descend along the guide path formed by the guide column 53 and the guide sleeve 52. Since the elastic pad 565 below the pressing plate 563 is closer to the cutting platform 67, it will first contact the skin and initially fit; the cutting telescopic cylinder 57 continues to push the mounting frame 54 to descend, and the spring 564 on the pressing plate 563 is compressed to generate elastic force, so that the elastic pad 565 tightly presses the skin to avoid displacement of the skin during cutting; then the cutter die 55 on the mounting frame 54 contacts the skin to complete the cutting action by the cutting edge. After the cutting is completed, the cutting telescopic cylinder 57 is reset, the mounting frame 54 drives the cutter die 55 to ascend, the spring 564 is elastically released, and the pressing plate 563 ascends synchronously with the mounting frame 54 to separate from the surface of the skin.

[0047] The cut skin is temporarily left on the cutting platform 67, and at this time the turnover telescopic cylinder 68 is retracted to pull the lifting plate 62 to descend along the slide rail of the support plate 61. The turnover shaft 63 on the lifting plate 62 is lowered, the guide wheel 65 at the end of the turnover crank 64 slides along the polyline guide groove 66 on the support plate 61, drives the turnover shaft 63 to first vertically descend and then realize 90° turnover through the arc segment of the guide groove 66, so that the cutting platform 67 is tilted downward. The skin falls into the material collecting box 20 below due to its own gravity; at the same time that the turnover telescopic cylinder 68 is lowered, the driving motor 8 operates (synchronously with waste rolling), the large gear 14 on the output shaft drives the small gear 13 of the cleaning shaft 11 to rotate, the cleaning shaft 11 rotates at high speed, and the cleaning brush 12 is scattered by centrifugal force, contacts the surface of the cutting platform 67, sweeps the residual skin into the material collecting box 20, and cleans the platform surface stains.

[0048] After the unloading is completed, the turnover telescopic cylinder 68 extends to push the lifting plate 62 to ascend, the guide wheel 65 slides reversely along the guide groove 66, and the cutting platform 67 is rotated by the turnover shaft 63 to reset to the horizontal state. Then the above cutting and unloading processes are repeated.

[0049] Through the orderly linkage of various components, the device can complete the whole process operation from raw material conveying, accurate cutting to automatic unloading and platform cleaning without manual intervention, realizes the automatic batch production of the skin, improves the production efficiency, and guarantees the stability of the cutting quality.

[0050] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
