DETAILED DESCRIPTION

[0046] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0047] The utility model provides a punching device for cow leather manufacturing, according to the attached manual Figure 1 To Attachment Figure 6 It can be seen that a punching device for manufacturing cowhide leather mainly includes the following parts or components: a working platform 10, a lifting platform 20, a first screw rod 30, a traction mechanism 40, and a fixing mechanism 60. The connection relationship of each part or component is as follows:

[0048] A first through hole 11 is provided in the middle of the working platform 10, a waste box 12 is provided below the first through hole 11, and a flattening mechanism 13 is provided on the first side of the working platform 10 for flattening the cowhide leather; the lifting platform 20 can slide up and down in the guide groove 21 on the working platform 10, and a connecting shaft 22 is provided at its bottom, and a punching head 23 corresponding to the first through hole 11 is provided below the connecting shaft 22; the first screw rod 30 is vertically provided on the working platform 10, and is threadedly connected to and penetrates the lifting platform 20, and the first screw rod 30 can rotate under the drive of the first motor 31; the traction mechanism 40 is provided on the second side of the working platform 10, and is connected to the first screw rod 30 through a transmission assembly. When the first screw rod 30 drives the lifting platform 20 to rise, the traction mechanism 40 can drive the cowhide leather to move forward under the action of the transmission assembly; the fixing mechanism 60 is provided on the connecting shaft 22 for fixing the cowhide leather.

[0049] Before punching the cowhide, the cowhide is first flattened by the flattening mechanism 13 to ensure that the surface of the cowhide is flat and improve the accuracy and consistency of the punching. When the cowhide moves to the bottom of the punching head 23, the first motor 31 drives the first screw 30 to rotate, thereby lowering the lifting platform 20, and the punching head 23 punches the cowhide. The waste generated during the punching can fall into the waste box 12 through the first through hole 11, ensuring the cleanliness of the working platform 10. During the punching, the fixing mechanism 60 can fix the cowhide to ensure that the cowhide maintains a stable position during the punching process, effectively avoiding the cowhide from stretching due to the elasticity of the cowhide during the punching process, causing damage to the cowhide, and ensuring the quality of the finished cowhide. It can also prevent the cowhide from moving or shaking during the punching, thereby improving the accuracy of the punching.

[0050] After the punching is completed, the first motor 31 drives the first screw 30 to rotate in the opposite direction. While driving the lifting platform 20 to rise, it can also control the traction mechanism 40 through the transmission component to drive the cowhide leather to move forward and automatically adjust the position of the cowhide leather to facilitate the subsequent punching head 23 to punch the cowhide leather. The operation is simple and the production efficiency is effectively improved.

[0051] As an embodiment, according to the attached Figure 1It can be seen that the flattening mechanism 13 includes: two flattening supports 131 symmetrically arranged on the first side of the working platform 10, and the two flattening supports 131 are both provided with flattening through grooves 132, and each flattening through groove 132 is slidably connected with a flattening block 133; both ends of a flattening roller 134 are respectively connected to the rotating shafts of the two flattening blocks 133; a first guide shaft 135 is vertically arranged on one of the flattening blocks 133, and is slidably connected to and penetrates the corresponding flattening support 131; a second screw rod 136 is rotatably arranged on the other flattening block 133, and is threadedly connected to and penetrates the corresponding flattening support 131. A hand wheel 137 is arranged at the upper end of the second screw rod 136. The outer surface of the flattening roller 134 is coated with a rubber coating.

[0052] During the process of moving, the cowhide leather will be located between the flattening roller 134 and the working platform 10. The cowhide leather is flattened by squeezing the flattening roller 134, and the distance between the flattening roller 134 and the working platform 10 can be adjusted to accommodate cowhide leathers of different thicknesses. When the hand wheel 137 is turned, the second screw 136 can be driven to rotate synchronously, thereby driving the corresponding flattening block 133 to rise and fall, so as to adjust the height of the flattening roller 134. The screw transmission has self-locking properties. After adjusting the height of the flattening roller 134, it can ensure that the minor adjustments made can be accurately maintained in place without errors due to external vibration or force interference, and there is no need to worry too much about accidental changes in position.

[0053] As an embodiment, according to the attached Figure 1 It can be seen that the traction mechanism 40 includes: two fixed seats 42 are respectively provided at both ends of the mobile platform 41, and the two fixed seats 42 are respectively slidably arranged on two second guide rods 43 on the working platform 10, and the mobile platform 41 can move along the second guide rods 43 under the action of the transmission component; the middle parts of the two clamping rods 44 are respectively hinged to the upper ends of the two fixed seats 42, and the opposite first ends of the two clamping rods 44 are provided with pressure heads 45; the driving component 46 is arranged on the mobile platform 41 and is connected to the second ends of the two clamping rods 44, and is used to drive the two clamping rods 44 to rotate.

[0054] The driving component 46 controls the rotation of the two clamping rods 44 so that the pressure heads 45 at the first ends of the two clamping rods 44 firmly press the leather onto the mobile platform 41. At this time, when the lifting platform 20 rises, the transmission component can drive the mobile platform 41 to move away from the punching head 23, thereby driving the cowhide leather to move forward. There is no need to manually adjust the position of the cowhide leather, thereby effectively improving work efficiency.

[0055] In this embodiment, according to the specification Figure 1It can be seen that the driving component 46 includes: two guide channels 461 are symmetrically arranged at both ends of the mobile platform 41 and connected through the first platform 462; two driving rods 463 are slidably arranged in the two guide channels 461, respectively, and each driving rod 463 has a hinged rod 464 at the upper end, and the free end of the hinged rod 464 is hinged to the second end of the corresponding clamping rod 44, and the lower ends of the two driving rods 463 are connected through the second platform 465; the second motor 466 is arranged on the first platform 462, and a third screw 467 is arranged at its output end, and the third screw 467 is threadedly connected to and penetrates the second platform 465.

[0056] When the second motor 466 drives the third screw rod 467 to rotate, it can drive the second platform 465 to rise and fall. When the second platform 465 descends, it drives the two driving rods 463 to descend at the same time. During the descent of the driving rod 463, it will drive the corresponding clamping rod 44 to rotate through the hinge rod 464, so that the pressure head 45 at the first end of the clamping rod 44 is away from the mobile platform 41, avoiding that the mobile platform 41 drives the cowhide leather to move when it moves. On the contrary, when the second platform 465 rises, it can drive the two driving rods 463 to rise, so that the pressure head 45 at the first end of the clamping rod 44 will firmly press the cowhide leather on the mobile platform 41. When the transmission assembly drives the mobile platform 41 to move along the second guide rod 43, it can drive the cowhide leather to move synchronously. It is suitable for cowhide leather of different thicknesses and can firmly fix the cowhide leather.

[0057] In this embodiment, according to the specification Figure 1 It can be seen that the transmission assembly includes: a first gear 51 is arranged on the first screw 30; a first rack 52 is slidably arranged in the first slideway below the working platform 10 and meshed with the first gear 51, and one end of the first rack 52 is connected to the moving platform 41.

[0058] When the first motor 31 drives the first screw 30 to rotate clockwise, it can drive the lifting plate to rise and at the same time drive the first gear 51 to rotate synchronously. The first rack 52 meshing with the first gear 51 can drive the movable platform 41 to move along the second guide rod 43 in the direction away from the punching head 23. On the contrary, when the first motor 31 drives the first screw 30 to rotate counterclockwise, it drives the lifting plate to descend and at the same time, the first rack 52 meshing with the first gear 51 drives the movable platform 41 to move in the direction of the punching head 23. The structure is simple and easy to use.

[0059] In this embodiment, according to the specification Figure 1It can be seen that the fixing mechanism 60 includes: a clamping seat 61 is composed of a first support plate 62, a second support plate 63 and a third support plate 64 connecting the first support plate 62 and the second support plate 63 which are arranged in parallel; the first support plate 62 is slidably arranged on the connecting shaft 22, and a second through hole 65 is arranged on the third support plate 64; a first spring 66 is sleeved on the connecting shaft 22, and its two ends respectively abut against the lifting platform 20 and the first support plate 62.

[0060] When the lifting platform 20 descends, the pressing seat 61 can be driven to descend synchronously. When the pressing seat 61 is against the cowhide leather, the lifting platform 20 continues to descend. The pressing seat 61 continues to apply force to the cowhide leather under the action of the first spring 66 to fix the cowhide leather. At this time, the punching head 23 is located between the first support plate 62 and the second support plate 63. After the lifting platform 20 continues to descend, the pressing seat 61 remains stationary, and the punching head 23 continues to descend until the punching head 23 penetrates the second through hole 65, completing the punching operation on the cowhide leather.
