[0033] Refer to Figure 1 And Figure 2, a wire roller is rotatably arranged between two fixed blocks 7, so that the leather material can be attached to the base 1, thereby improving the edge wrapping effect.
[0034] In this embodiment, during use, the operator places the winding roller 9 between two fixed disks and inserts the adjusting block into the adjusting groove 13. Then, the operator pulls the handwheel 22, so that the limiting frame 24 is disengaged from the limiting groove 23. Then, the operator rotates the handwheel 22, so that the driving column 21 can drive the driving disk 19 to rotate, and at the same time, the rotating shaft moves around the driving disk 19. During this process, the positioning plate 17 can be pulled to move relatively through the driving rod 20, and at the same time, the positioning block 16 is pushed into the positioning groove 15 through the positioning rod 18. Furthermore, the fixing of the adjusting block is realized through the cooperation of the positioning block 16 and the positioning groove 15. After the fixing of the adjusting block is completed, the operator releases the handwheel 22, so that the driving column 21 pulls the handwheel 22 to move under the action of the limiting spring 25, so that the limiting frame 24 extends into the limiting groove 23, and further, the limiting of the rotation angle of the handwheel 22 is realized through the cooperation of the limiting frame 24 and the limiting groove 23. Then, the operator passes the leather material through the gap between the first feeding roller 3 and the second feeding roller 4 and winds it around the winding roller 9. The rotation of the second feeding roller 4 and the winding roller 9 can be controlled by the operation of the first motor 5 and the second motor 11, so that while the leather material is fed, the problem of deviation caused by external force is prevented.
[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
