[0030] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0032] Reference Figure 1-5The utility model provides an embodiment: a trimming device for cowhide processing, comprising a base 1, a plurality of support rods 2 are fixedly connected to the side walls at both ends of the base 1, the opposite surfaces of the support rods 2 are fixedly connected to the outer wall of the annular frame 3, the inner wall lower end of the annular frame 3 is evenly provided with inner teeth 4, the inner wall of the annular frame 3 is rotatably connected with a rotating frame 5, a self-locking component is provided on one side bottom wall of the rotating frame 5, positioning holes 12 are symmetrically opened on both side walls of the rotating frame 5, the middle part of the rotating frame 5 is hollowed out and slidably connected with a slider 7, the middle part of the slider 7 rotates A handle 6 is movably connected, and a rotating block 23 is fixedly connected to the middle side wall of the handle 6. Positioning holes 12 are symmetrically opened on both side walls of the slider 7 and the rotating block 23. The inner walls of the positioning holes 12 are slidably connected to the outer walls of the latch 13. The latch 13 simultaneously and straightly passes through the positioning holes 12 opened on the side walls of the slider 7, the rotating frame 5 and the rotating block 23. A hydraulic rod 24 is installed on the outer wall of the bottom end of the handle 6, and a trimming knife 11 is fixedly connected to the bottom end of the hydraulic rod 24. A trimming platform 10 is slidably connected to the outer wall of the top end of the base 1, and sliding plates 8 are slidably connected to the top walls of the base 1.

[0033] Specifically, the support rod 2 can be a telescopic rod structure to facilitate the overall adjustment of the height of the annular frame 3 and the trimming knife 11. The outer walls of the left and right ends of the rotating frame 5 are embedded in the interior of the annular frame 3 and are rotatably connected to the annular frame 3. After the trimming knife 11 is adjusted to a suitable position, when the openings of the positioning holes 12 of the slider 7, the rotating frame 5 and the rotating block 23 coincide, the pin 13 can be inserted to fix the slider 7, the rotating frame 5 and the rotating block 23 at the same time. At this time, the trimming knife 11 is fixed synchronously.

[0034] The self-locking assembly includes a latch 22, which is meshed with the inner teeth 4, and the top outer wall of the latch 22 is rotatably connected to the bottom outer wall of the rotating frame 5. A rotating shaft fixing block 20 is fixedly connected below the rotation connection between the latch 22 and the rotating frame 5, and a support plate 18 is fixedly connected to the right side of the bottom outer wall of the rotating frame 5. A spring 21 is provided between a side wall of the support plate 18 and the inner side wall of the latch 22. A limit block 17 is fixedly connected to the left side of the bottom outer wall of the rotating frame 5, and a push rod 16 is slidably connected to the middle of the limit block 17. A push block 15 is fixedly connected to the left outer wall of the push rod 16, and a rubber block 19 is rotatably connected to the right outer wall of the push rod 16.

[0035] Specifically, the rotating frame 5 can rotate clockwise at a certain angle under the influence of the inner teeth 4 and the latch teeth 22, and cannot rotate counterclockwise. When rotating clockwise, the inner teeth 4 fit with the bottom end of the long side of a meshing latch tooth 22 and slowly slide relative to each other. At this time, the spring 21 is in a gradually compressed state until the inner teeth 4 and the other end point of the long side of the latch tooth 22 are just offset. Then, the long side of the latch tooth 22 returns to the bottom end of the long side of the next inner tooth 4 under the action of the spring 21.

[0036] The right outer wall of the rubber block 19 just fits the right inner wall of the latching tooth 22 .

[0037] Slide grooves 9 are provided on both sides of the outer wall of the top end of the base 1 .

[0038] Specifically, pressing the push block 15 will force the push rod 16 to move to the other side, and the rubber block 19 will gradually stick to the inner wall of the right end of the latch tooth 22 until the right side of the latch tooth 22 is pushed to move toward the right rear. At this time, the spring 21 is compressed until the long side end of the latch tooth 22 leaves the top end of the long side of the inner tooth 4 with which it meshes. In this state, the push block 15 is continuously pressed to realize the bidirectional arbitrary rotation of the rotating frame 5, so as to more quickly select the fixed angle of the trimming knife 11.

[0039] Specifically, the position of the support plate 18 does not overlap with the sliding track of the push rod 16 .

[0040] The outer walls of the upper and lower ends of the slider 7 are both provided with rotation holes 14 . The radius of the rotation block 23 is larger than the radius of the rotation hole 14 . The rotation block 23 is rotatably connected to the inner wall of the slider 7 .

[0041] Specifically, the radius of the rotating block 23 is greater than the radius of the rotating hole 14 to ensure that the handle 6, the hydraulic rod 24 and the repair knife 11 will not fall due to gravity. The rotating block 23 can slide on the inner wall of the slider 7 to achieve the self-rotation ability of the repair knife 11.

[0042] Working principle: Pull open the trimming platform 10 that is slidably connected on the base 1, and place the cowhide leather material on it, then reset the trimming platform 10, and use the sliding plate 8 to flatten the cowhide leather material, or fix the cowhide leather material in the required position, then rotate the rotating frame 5, slide the slider 7 and turn the handle 6 to place the trimming knife 11 in the ideal position, then use the pin 13 to pass through the positioning hole 12 to ensure that the trimming knife 11 remains stable during the trimming process, and then start trimming. During the trimming process, the pin 13 can be pulled out at any time to conveniently adjust the position of the trimming knife 11. Insert the latch 13 back, and the rotating frame 5 can force the latch teeth 22 to leave the meshing state with the inner teeth 4 by pressing the push block 15. At this time, the rotating frame 5 can be quickly rotated in both directions. After releasing the push block 15, the fixing of the rotating frame 5 is completed. In addition, even if the push block 15 is pressed and the rotating frame 5 is directly rotated clockwise with a greater force, the rapid angle adjustment can be completed. After the trimming is completed, the leather trimming product on the trimming platform 10 is taken away, and the sliding plate 8 can be slid again to push the remaining waste leather scraps on the surface of the base 1 to one place for subsequent processing.
