Description

Technical Field

[0001] The present application relates to the technical field of electroplating equipment, and in particular to an electroplating device for processing a hydraulic support pin shaft. Background Art

[0002] A pin is a standardized fastener, typically locked with a cotter pin. It provides reliable operation and easy disassembly. During the pin manufacturing process, it is electroplated to improve its rust resistance. During electroplating, the pin is clamped and secured with a fixture. After securing, both the fixture and the pin are placed in a plating bath for electroplating.

[0003] For example, the Chinese patent document with the announcement number CN117166029B discloses an automatic rust-proof coating device for processing loader pin shafts, comprising an electroplating box and two groups of support assemblies arranged at the upper end of the electroplating box, wherein the support assemblies include support legs, the upper ends of the support legs are fixedly connected to a rail, the inner side of the rail is slidably connected to a slide, the rear end of the electroplating box is provided with a drive assembly for pushing the slide to slide inside the rail, and an electroplating rack is provided between the two groups of support assemblies, wherein the electroplating rack includes a crossbar, the lower end of the crossbar is provided with two groups of mounting rods, the outer side of the mounting rod is slidably connected to a sliding assembly for placing the pin shaft, and the rear end of the mounting rod is provided with a stirring assembly for assisting the sliding assembly to slide. The drive assembly pushes the slide to move back and forth on the rail, causing the crossbar and the sliding assembly for placing the pin shaft to reciprocate, thereby driving the shaft pin to reciprocate, ensuring uniform electroplating of the shaft pin.

[0004] In the above-mentioned related technologies, during the electroplating process, the pin is fixed on the sliding assembly by a hook. The contact position of the pin and the hook does not change during the reciprocating movement of the pin driven by the sliding assembly. During the electroplating process, the electroplating effect of the contact position between the pin and the hook is not good. In addition, the pin is suspended on the hook through its own mounting hole. In addition, when the pin to be electroplated does not have a mounting hole, it is necessary to replace a different clamp to fix the pin, which is extremely inconvenient in use. Summary of the Invention

[0005] The present application provides an electroplating device for processing a hydraulic support pin shaft, aiming to solve the problem of poor electroplating effect of the pin shaft in the related art.

[0006] The electroplating device for processing the pin of a hydraulic support provided in this application adopts the following technical solution:

[0007] 18. The repairing kit for automotive dents, according to claim 1, wherein a bottom of the foot stand comprises a through-hole, and the two foot pieces comprise two bosses, wherein the bosses comprise a through-hole, a screw bolt, and a nut. The through-hole, the bosses comprise a through-hole, a screw bolt, and a nut. The through-hole, the bosses comprise a through-hole, a screw bolt, and a nut. The through-hole, the bosses comprise a through-hole, a screw bolt, and a nut.

[0008] By adopting the above technical solution, when the pin needs to be electroplated, the pin is first placed on the support plate, and then the first clamping assembly and the second clamping assembly are driven to approach each other by the pushing assembly, and the pin to be electroplated is fixed by the clamping channels on the first clamping assembly and the second clamping assembly. When the pin is in the clamping channel, the surface of the pin will abut against the surface of the clamping roller. Since the diameter of the clamping roller gradually decreases in the direction away from the mounting frame, the clamping channel formed at this time will gradually increase in the direction away from the mounting frame. When the diameter of the pin becomes smaller, the length of the pin extending into the clamping channel becomes longer, so that pins of different diameters can be clamped. When there is no mounting hole on the pin, the pin can still be fixed. In addition, since the control assembly can drive the multiple clamping rollers to rotate, during the rotation of the clamping rollers, the friction between the clamping rollers and the pin can drive the pin itself to rotate. Since the pin can rotate, the contact position of the pin and the clamping roller will change continuously, and then the contact position of the clamping roller can be electroplated, so that the electroplating of the pin surface is more uniform.

[0009] Optionally, the pushing assembly includes a sliding rod slidably connected to the lifting frame, a pushing rod fixed on the sliding rod, and a lifting assembly arranged on the sliding rod, the lifting assembly is used to be connected to the mounting frame, and a pushing groove is provided in the electroplating pool for driving the pushing rod to move back and forth, the pushing groove includes a first vertical portion, an inclined portion and a second vertical portion, the inclined portion is used to connect the first vertical portion and the second vertical portion, and the second vertical portion is arranged close to the clamping roller, and the pushing rod is slidably connected in the pushing groove.

[0010] By adopting the above technical solution, during the downward movement of the lifting frame, the push rod first moves into the first vertical part, and during the subsequent movement, the push rod will move from the first vertical part to the inclined part. During the movement, the push rod, the sliding rod and the lifting assembly will move, and the mounting frame will be driven to move toward the direction close to the pin shaft, so that the pin shaft moves into the clamping channel, thereby achieving the purpose of facilitating the movement of multiple clamping rollers.

[0011] Optionally, the control component includes a plurality of first control gears fixed on the clamping rollers and a second control gear rotatably connected to the mounting frame, the plurality of first control gears and the plurality of clamping rollers correspond one-to-one, and the second control gears are meshed with the plurality of first control gears, and a driving component for driving the second control gears to rotate is provided on the lifting frame.

[0012] By adopting the above technical solution, the driving assembly drives the second control gear to rotate, the second control gear drives multiple first control gears on the mounting frame to rotate simultaneously, and then the multiple first control gears drive multiple clamping rollers to rotate simultaneously, which then facilitates the rotation of the pin shaft in the clamping channel.

[0013] Optionally, the lifting assembly includes a connecting rod hinged on the sliding rod, a lifting rod rotatably connected to the connecting rod, and a connecting spring fixed to the connecting rod, one end of the connecting spring away from the connecting rod is fixed to the sliding rod, one end of the lifting rod away from the connecting rod is hinged on the mounting frame, and the mounting frame slides on the lifting frame in a vertical direction.

[0014] By adopting the above technical solution, during the process of the pushing rod moving in the inclined part, the pushing rod will first move simultaneously with the sliding rod and the connecting rod. During the movement, due to the action of the gravity of the control component and multiple clamping rollers, the lifting rod on the connecting rod will move toward the end of the support plate in an initial inclined state. At this time, the pin shaft on the support plate is clamped and fixed by the first clamping component and the second clamping component; after the first clamping component and the second clamping component clamp the pin shaft, the pushing rod still slides in the inclined part, at this time the connecting spring will be compressed, and the compressed connecting spring will push the connecting rod to move, and then under the action of the lifting rod, the mounting frame and the first clamping component set on the mounting frame will be pushed upward, and the pin shaft will be driven to move upward during the movement. The upward moving pin shaft no longer abuts against the surface of the support plate, and then the surface of the pin shaft can be better electroplated.

[0015] Optionally, the drive assembly includes a first drive shaft fixed on a second control gear, a second drive shaft rotatably connected to a mounting frame, a drive gear fixed on the second drive shaft, and a drive rack fixed in the electroplating pool, the drive gear and the drive rack are engaged, the second drive shaft slides in a vertical direction and rotates on a lifting frame, and the first drive shaft is slidably connected to the second drive shaft.

[0016] By adopting the above technical solution, the driving gear will be driven to move downward during the downward movement of the lifting frame. During the downward movement of the driving gear, it will engage with the driving rack in the electroplating pool. Then, the driving gear will be rotated during the continued downward movement. During the rotation of the driving gear, the first driving shaft and the second driving shaft will be driven to rotate, and the second control gear will be driven to rotate through the first driving shaft.

[0017] Optionally, a pulling spring is provided on the second driving shaft, one end of the pulling spring is fixed on the first driving shaft, and the other end is fixed on the second driving shaft.

[0018] By adopting the above technical solution, after the lifting frame is taken out of the electroplating tank, the spring can be pulled to pull the mounting frame to the far left, so that the mounting frame remains at the far left, which facilitates the subsequent clamping of the pin shaft.

[0019] Optionally, a booster assembly for increasing the fluidity of the electroplating liquid at both ends of the pin shaft is provided on the clamping roller, and the booster assembly includes a booster airbag fixed on the clamping roller and an arc-shaped extrusion ring fixed on the mounting frame. The arc-shaped extrusion ring and the clamping roller are spaced apart, and an extrusion channel for extruding the booster airbag is formed between the arc-shaped extrusion ring and the clamping roller, and a booster hole is provided on the side of the booster airbag facing away from the mounting frame.

[0020] By adopting the above technical solution, the boost airbag will be driven to rotate during the rotation of the clamping roller. During the rotation of the boost airbag, the boost airbag will enter the extrusion channel and squeeze the electroplating liquid in the boost airbag through the extrusion channel. During the extrusion process, the electroplating liquid will flow out of the boost airbag at a high speed, which will increase the fluidity of the electroplating liquid at both ends of the pin shaft. After the boost airbag and the extrusion channel are separated, the boost airbag will return to its original state due to its own characteristics. In the process of returning to its original state, part of the electroplating liquid will be sucked into the boost airbag. At this time, the flow of the electroplating liquid will still be increased, thereby improving the electroplating effect at both ends of the pin shaft.

[0021] Optionally, a curved surface is provided on one side of the support plate close to the pin shaft.

[0022] By adopting the above technical solution, the arcuate surface is used to increase the contact area with the pin shaft, thereby making the pin shaft more stable when placed on the support plate.

[0023] Optionally, the mounting bracket is provided with an abutment rod for abutting against the end face of the pin shaft.

[0024] By adopting the above technical solution, when the diameter of the pin shaft to be electroplated is small and cannot be coaxially arranged with the clamping channel surrounded by multiple clamping rollers, the pin shaft will abut against the clamping roller below under the action of gravity. During the horizontal movement of the mounting frame, the abutment rod can abut against the end face of the pin shaft, thereby limiting the pin shaft placed on the clamping roller below.

[0025] Optionally, an inclined surface is provided on the arc-shaped extrusion ring.

[0026] By adopting the above technical solution, under the action of the inclined surface, the extrusion airbag can better enter the gap between the arc-shaped extrusion ring and the clamping roller.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. The control component can drive multiple clamping rollers to rotate. During the rotation of the clamping rollers, the friction between the clamping rollers and the pin shaft can drive the pin shaft itself to rotate. Since the pin shaft can rotate, the contact position between the pin shaft and the clamping roller will always change, and then the contact position of the clamping roller can be electroplated to make the pin shaft surface more evenly electroplated.

[0029] 2. After the lifting frame is taken out of the electroplating tank, pull the spring to pull the mounting frame to the far left, so that the mounting frame remains at the far left, which makes it easier to clamp the pin shaft later.

[0030] 3. During the rotation of the boost airbag, the boost airbag will enter the extrusion channel and squeeze the electroplating liquid in the boost airbag through the extrusion channel. During the extrusion process, the electroplating liquid will flow out of the boost airbag at a high speed, which will increase the flow rate of the electroplating liquid at both ends of the pin shaft.

[0039] The following combination Figure 1-Figure 7 This application is described in further detail.

[0040] The embodiment of the present application discloses an electroplating device for processing a hydraulic support pin. Figures 1 to 3 A plating device for processing a hydraulic support pin includes an electroplating pool 01 set on the ground and a lifting frame 02 for extending into the electroplating pool 01. The lifting frame 02 is used to connect to a sling, and is placed into the electroplating pool 01 or taken out of the electroplating pool 01 through the sling and the lifting frame 02. In this embodiment, the lifting frame 02 is driven by the sling to reciprocate up and down in the electroplating pool 01, thereby improving the fluidity of the electroplating solution. In addition, a plurality of clamping devices for fixing the pin are provided on the lifting frame 02. The plurality of clamping devices are evenly spaced along the vertical direction. The clamping devices include a first clamping assembly 1 and a second clamping assembly 03. The first clamping assembly 1 and the second clamping assembly 03 are used to clamp the two ends of the pin, and the structures of the first clamping assembly 1 and the second clamping assembly 03 are the same. In this embodiment, the structure of the second clamping assembly 03 is not described in detail. In addition, a control component 2 for driving the clamping roller 12 to rotate is provided on the mounting frame 11, and a pushing component 3 is provided on the mounting frame 11. Multiple pushing components 3 are provided, and multiple pushing components 3 are provided corresponding to the first clamping component 1 and the second clamping component 03. The pushing component 3 pushes the first clamping component 1 and the second clamping component 03 closer to each other, and then the pin shaft can be clamped.

[0041] Reference Figures 1 to 3The first clamping assembly 1 includes a mounting frame 11 arranged on the lifting frame 02 and a plurality of clamping rollers 12 rotatably connected to the mounting frame 11. The plurality of clamping rollers 12 are arranged along a circular array, and a plurality of support plates 04 are arranged on the lifting frame 02. The plurality of support plates 04 correspond one to one to the plurality of clamping devices. The support plate 04 is used to place the pin shaft. The first clamping assembly 1 and the second clamping assembly 03 are arranged at both ends of the support plate 04, and an arc surface is provided on the support plate 04. Under the action of the arc surface, the contact area between the pin shaft and the support plate 04 can be increased, and then the support effect of the pin shaft is better.

[0042] Reference Figures 2 to 4 The clamping roller 12 includes a mounting portion 121 and an abutting portion 122. The mounting portion 121 is a cylindrical structure that is rotatably connected to the mounting frame 11 and is used to connect to the control component 2. The abutting portion 122 is used to abut the pin shaft. The diameter of the abutting portion 122 gradually decreases as it moves away from the mounting portion 121, making the abutting portion 122 a frustum-shaped structure. Since the multiple clamping rollers 12 are arranged in a ring shape, a clamping channel 05 is formed between the multiple clamping rollers 12. The vertical cross-section of the clamping channel 05 gradually increases as it moves away from the mounting frame 11. When clamping and fixing the pin shaft, the pin shaft will be inserted into the clamping channel 05. The smaller the diameter of the pin shaft, the longer the length inserted into the clamping channel 05. In this embodiment, the number of clamping rollers 12 is set to four, and the pin shaft can be clamped and fixed by the four clamping rollers 12.

[0043] Reference Figures 2 to 4 Abutment rod 06 is fixedly mounted on the mounting frame 11, and abutment rods 06 are provided at both ends of the support plate 04. When the diameter of the end portion of the pin shaft to be clamped is small, the abutment rod 06 can be abutted against the end surface of the pin shaft, and then the pin shaft is clamped and fixed by the two abutment rods 06. In order to reduce the contact area between the abutment rod 06 and the pin shaft, the diameter of the abutment rod 06 can be set as needed.

[0044] Reference Figures 2 to 4The pushing assembly 3 includes a sliding rod 31 slidably connected to the lifting frame 02 and a pushing rod 32 fixed to the sliding rod 31. The end of the sliding rod 31 away from the pushing rod 32 is provided with a lifting assembly 4. The sliding rod 31 is connected to the mounting frame 11 through the lifting assembly 4. At the same time, a mounting plate 07 is provided in the electroplating tank 01. The mounting plate 07 is provided with a pushing groove 5 for driving the pushing rod 32 to move. Under the action of the pushing groove 5, the pushing rod 32 is driven to move left and right on the lifting frame 02, and then the lifting assembly 4 and the sliding rod 31 can be driven to move, so that the mounting frame 11 drives the clamping roller 12 to move in the direction close to the pin shaft. When the first clamping assembly 1 and the second clamping assembly 03 approach each other, the pin shaft on the support plate 04 can be clamped. In this embodiment, in order to improve stability, each pushing rod 32 corresponds to two mounting plates 07. The two mounting plates 07 are arranged in parallel and spaced apart. The pushing rod 32 is located between the two mounting plates 07, and the two ends of the pushing rod 32 slide in the pushing grooves 5 on the two mounting plates 07.

[0045] Reference Figures 2 to 4 The pushing groove 5 includes a first vertical portion 51, an inclined portion 52 and a second vertical portion 53. One end of the inclined portion 52 is connected to the first vertical portion 51, and the other end is connected to the second vertical portion 53. The distance between the first vertical portion 51 and the end surface of the support plate 04 is greater than the distance between the second vertical portion 53 and the end surface of the support plate 04. In the initial state, the lifting frame 02 extends out of the electroplating pool 01, and the pushing rod 32 corresponds to the first vertical portion 51. In the process of the lifting frame 02 moving downward, it will first enter the first vertical portion 51, and then enter the inclined portion 52 through the first vertical portion 51. At this time, the pushing rod 32 will slide in the inclined portion 52, and will move toward the end of the support plate 04 during the sliding process, and then push the sliding rod 31 and the lifting assembly 4 to drive the mounting frame 11 to slide on the lifting frame 02, and then the pin shaft can be extended into the clamping channel 05.

[0046] Reference Figures 2 to 4 The lifting assembly 4 includes a connecting rod 41 slidably connected to the sliding rod 31, a lifting rod 42 hinged on the connecting rod 41, and a connecting spring 43 fixed on the connecting rod 41. The connecting rod 41 is passed through the sliding rod 31, and the end of the connecting spring 43 away from the connecting rod 41 is fixed to the sliding rod 31, and the end of the lifting rod 42 away from the connecting rod 41 is hinged on the mounting frame 11. In this embodiment, when the pushing rod 32 is in the first vertical portion 51, the connecting spring 43 is at a natural length in the initial state.

[0047] Reference Figures 2 to 4, the pushing rod 32 will push the sliding rod 31 to move during the sliding process in the inclined portion 52, and the sliding rod 31 will drive the connecting spring 43, the connecting rod 41 and the lifting rod 42 to move during the movement. Due to the action of the mounting frame 11 and the clamping roller 12 set on the mounting frame 11, the gravity of the mounting frame 11 is relatively large at this time. When the connecting rod 41 drives the lifting rod 42 to move, the lifting rod 42 will push the mounting frame 11 to slide left and right on the lifting frame 02, and will not cause the lifting rod 42 to rotate on the connecting rod 41. When the two ends of the pin abut against the clamping roller 12 At this time, as the pushing rod 32 continues to move, the mounting bracket 11 cannot continue to move, the connecting spring 43 is compressed, and the connecting spring 43 pushes the connecting rod 41 to move. Then, since the mounting bracket 11 cannot move horizontally, the lifting rod 42 will rotate on the connecting rod 41. Under the action of the lifting rod 42, the mounting bracket 11 will move upward. The movement of the mounting bracket 11 will drive the clamping roller 12 and the pin fixed by the clamping roller 12 to move upward, so that the pin is separated from the support plate 04, so that the pin and the electroplating solution can be better contacted during electroplating.

[0048] In this embodiment, since multiple clamping devices are arranged in the vertical direction, when the multiple clamping devices are moved into the electroplating pool 01, the pushing rods 32 corresponding to the multiple clamping devices are all in the second vertical part 53, and then the pin shafts clamped by each clamping device are separated from the surface of the support plate 04. During the process of the sling driving the lifting frame 02 to move back and forth up and down, the pushing rod 32 is still in the second vertical part 53.

[0049] Reference Figures 2 to 7 The control component 2 includes a plurality of first control gears 21 fixedly connected to the clamping roller 12 and a second control gear 22 rotatably connected to the mounting frame 11. The plurality of first control gears 21 correspond to the plurality of clamping rollers 12 one by one, and in this embodiment, four first control gears 21 are provided. The second control gear 22 and the plurality of first control gears 21 are engaged at the same time, and then the plurality of first control gears 21 can be driven to rotate at the same time by rotating the second control gear 22. During the rotation of the first control gear 21, the corresponding clamping roller 12 will be driven to rotate. Due to the friction between the clamping roller 12 and the pin shaft, the pin shaft can be driven to rotate by the rotation of the clamping roller 12, and then the contact position between the clamping roller 12 and the pin shaft can be changed at all times, and then the electroplating of both ends of the pin shaft can be made more uniform.

[0050] Reference Figures 2 to 7To facilitate the rotation of the second control gear 22, a drive assembly 6 is provided on the lifting frame 02. The drive assembly 6 includes a mounting block 61 slidably connected to the lifting frame 02, a second drive shaft 62 rotatably connected to the mounting block 61, a first drive shaft 63 slidably connected to the second drive shaft 62, a drive gear 64 fixed to the second drive shaft 62, and a drive rack 65 fixed to the mounting plate 07. The drive gear 64 and the drive rack 65 are meshed. The first drive shaft 63 is fixed to the second control gear 22. The rotation of the second drive shaft 62 drives the first drive shaft 63 to rotate. The first drive shaft 63 drives the second control gear 22 to rotate, which in turn drives the plurality of first control gears 21 to rotate, thereby rotating the clamping roller 12. In this embodiment, the length of the drive rack 65 is the same as the length of the second vertical portion 53. The drive gear 64 only engages with the drive rack 65 when the push rod 32 moves into the second vertical portion 53.

[0051] Since the mounting plate 07 is arranged in the electroplating pool 01, the driving rack 65 is also arranged in the electroplating pool 01, and the driving rack 65 is arranged vertically, when the lifting frame 02 moves downward, the driving gear 64 will move into the electroplating pool 01, and then engage with the driving rack 65 in the electroplating pool 01. When the lifting frame 02 continues to descend, the push rod 32 moves into the second vertical portion 53, and under the action of the driving rack 65, the driving gear 64 will be driven to rotate, and finally it is convenient to drive the second control gear 22 to rotate.

[0052] Reference Figures 2 to 7 A pulling spring 7 is provided in the second driving shaft 62, one end of the pulling spring 7 is fixed to the second driving shaft 62, and the other end is fixed to the first driving shaft 63. When the pushing component 3 pushes the mounting bracket 11 to move horizontally, the mounting bracket 11 will drive the first driving shaft 63 to slide on the second driving shaft 62, so that the connecting spring 43 is in a stretched state. When the lifting component 4 drives the mounting bracket 11 to move upward, the first driving shaft 63 and the second driving shaft 62 will move upward at the same time. At this time, the mounting block 61 slides on the lifting bracket 02. In this embodiment, during the movement of the pushing rod 32 in the inclined portion 52, the driving rack 65 and the driving gear 64 are not yet engaged.

[0053] Reference Figures 2 to 7 A booster assembly 8 is provided on the mounting frame 11. The booster assembly 8 is used to increase the fluidity of the electroplating solution around the mounting frame 11. Multiple booster assemblies 8 are provided, and multiple booster assemblies 8 correspond one to one to multiple clamping rollers 12; the booster assembly 8 includes an arc-shaped extrusion ring 81 fixed on the mounting frame 11 and a booster airbag 82 fixed on the clamping roller 12. A booster hole 83 is opened in the booster airbag 82 near the support plate 04, and an inclined surface 84 is provided on the arc-shaped extrusion ring 81.

[0054] The inner diameter of the arc-shaped extrusion ring 81 is larger than the diameter of the mounting portion 121, and an extrusion channel 85 is formed between the extrusion ring and the mounting portion 121. Then, the pressurized airbag 82 is filled with electroplating liquid. During the rotation of the clamping roller 12, the pressurized airbag 82 enters the extrusion channel 85 and squeezes the pressurized airbag 82 through the extrusion channel 85. During the squeezing of the pressurized airbag 82, the electroplating liquid in the pressurized airbag 82 is squeezed out. Then, during the extrusion process, the electroplating liquid is discharged from the pressurized hole 83 at a faster speed, and the pressurized airbag 82 is squeezed out. It can push the plating liquid around the clamping roller 12, thereby increasing the fluidity of the plating liquid; after the boosting airbag 82 and the extrusion channel 85 are separated, the boosting airbag 82 returns to its original state. In the process of returning to its original state, a certain suction force will be generated to suck the plating liquid into the boosting airbag 82. In the process of sucking the plating liquid, the fluidity of the plating liquid around the clamping roller 12 will still be improved, thereby achieving a better electroplating effect; in addition, under the action of the inclined surface 84, the boosting airbag 82 can be better enabled to enter the extrusion channel 85.

[0055] The implementation principle of the electroplating device for processing the pin shaft of a hydraulic support in the embodiment of the present application is as follows: when the pin shaft needs to be electroplated, multiple pin shafts are placed on the support plate 04 respectively, and then the lifting frame 02 is driven to descend by the sling, and then the push rod 32 will move into the first vertical part 51, and then move from the first vertical part 51 to the inclined part 52. During the movement in the inclined part 52, the push rod 32 will move toward the end face of the support plate 04, and the push rod 32 will drive the sliding rod 31 and the connecting rod 41 and the setting lifting rod 42 to move to the right, and under the action of the lifting rod 42, the mounting frame 11 is driven It moves toward the end face of the support plate 04, and then the four clamping rollers 12 on the mounting frame 11 also move toward the end face of the support plate 04, so that the pin shaft is inserted into the clamping channel 05, and finally abuts against the surface of the four clamping rollers 12. Then, when the push rod 32 continues to move in the inclined portion 52, the connecting spring 43 in the sliding rod 31 will be compressed, and the connecting spring 43 pushes the connecting rod 41 to move. At this time, since the mounting frame 11 and the clamping roller 12 cannot move horizontally, the mounting frame 11 will drive the clamping roller 12 and the pin shaft in the clamping channel 05 to move upward, thereby causing the pin shaft to separate from the support plate 04.

[0056] The push rod 32 moves from the inclined portion 52 to the second vertical portion 53, the driving gear 64 and the driving rack 65 engage, and then the driving gear 64 drives the first driving shaft 63 and the second driving shaft 62 to rotate, and the second control gear 22 is driven to rotate through the first driving shaft 63, and the second control gear 22 drives the four first control gears 21 to rotate, and the four clamping rollers 12 on each mounting frame 11 are driven to rotate through the four first control gears 21. During the rotation of the clamping roller 12, the clamping pin shaft will be driven to rotate.
