Description

Technical Field

[0001] The utility model relates to the technical field of shoemaking, in particular to a winding device for leather used in shoemaking. Background Art

[0002] At present, the drum tanning method is generally used for leather tanning. The process is to put the naked leather and tanning liquid after a series of pre-tanning preparation processes into a drum and rotate it. The rotation of the drum plays a role in stirring the naked leather and the tanning liquid, and makes the naked leather subject to a certain degree of mechanical action, so as to complete the tanning process.

[0003] During the rotation of the drum, the naked leather continuously undergoes mechanical deformations such as stretching, extrusion, and bending, and a large amount of friction also occurs between the leathers. All these actions promote the penetration of the tanning liquid into the leather, but inevitably cause a certain degree of damage to the leather fibers. Specifically, after tanning, the grain surface of the leather is relatively rough, and the leather is loose at the edges and other parts.

[0032] In this embodiment, it includes a bottom plate 1. On the outer walls of both sides of the top of the bottom plate 1, vertical plates 2 are fixedly arranged. The vertical plates 2 at least serve as support members. There are four through holes at the four corners of the top of the bottom plate 1, which facilitate people to fix the bottom plate 1 on the ground or the workbench through bolts. The number of vertical plates 2 is two, and the two vertical plates 2 are symmetrically distributed above the bottom plate 1;

[0033] Specifically, the vertical plate 2 is jointly composed of a main body part 21 fixedly connected to the bottom plate 1, an extension part 22 installed on the outer wall of one side of the main body part 21, a bending part 23 installed on the outer wall of one side of the top of the main body part 21, and a support part 24 installed on the outer wall of the other side of the top of the main body part 21. The extension part 22 expands the middle part of the main body part 21, increases its thickness, facilitates the installation of the shock absorption spring 9, and at the same time improves the support strength of the vertical plate 2. Using the bending part 23 to the outside, the distance between the two bending parts 23 is increased, so that the roller shaft 31 can fall from top to bottom inside the chute 25 and be taken out from the discharge port of the bending part 23, with reasonable dimensions. The support part 24 is used for the installation of the following multiple components and plays a role in stably supporting the following multiple components. There are installation holes 26 on the support part 24, and the tensioning assembly 7 is arranged inside the installation holes 26;

[0034] Specifically, there is a chute 25 on the support part 24, and at the bottom of the chute 25, there is a shock absorption spring 9 inserted into the extension part 22. When the roller shaft 31 falls from above, the roller shaft 31 lands on the shock absorption spring 9, which can make the roller shaft 31 land stably below and be taken out from the discharge port, facilitating the taking out of the leather after winding is completed.

[0035] In this embodiment, at the top of the two vertical plates 2, there is a winding roller assembly 3, and the winding roller assembly 3 is at least used for winding the leather;

[0036] Specifically, the winding roller assembly 3 includes a roller shaft 31. On both outer sides of the roller shaft 31, there are socketed retaining plates 32. The outer part of the roller shaft 31 is slidably socketed with a bushing 33. The bushing 33 is fixedly arranged on one outer wall of the retaining plate 32. There is a positioning hole on one side of the bushing 33, and a locking bolt 34 is inserted into the positioning hole. On the outer part of one end of the roller shaft 31, there is a transmission gear 35. At the top of one outer wall of the vertical plate 2, there is an inlet and a shaft groove. And the roller shaft 31 is located inside the shaft groove. The roller shaft 31 enters the inside of the shaft groove from the inlet. By using the driving device 10 and the transmission member 11 to drive the transmission gear 35 to rotate, the roller shaft 31 can be driven to wind the leather. By loosening the locking bolt 34, the retaining plate 32 and the bushing 33 can slide freely on the roller shaft 31 to achieve the winding operation of leather with different widths.

[0037] In this embodiment, a limiting frame 4 is arranged at the top of the vertical plate 2. The limiting frame 4 is at least used to limit the winding roller assembly 3 inside the vertical plate 2.

[0038] Specifically, the limiting frame 4 includes a stud 41 arranged at the top of the vertical plate 2. At the top of the stud 41, there are fixedly arranged a plurality of handles 42. And at the bottom end of the stud 41, there is a contact plate 43. The contact plate 43 is rotatably connected to the bottom end of the stud 41. After the roller shaft 31 is placed inside the shaft groove, the operator can hold the handle 42 with his hand, so that the stud 41 drives the contact plate 43 at the bottom end to move downwards, making the contact plate 43 contact with the upper part of the roller shaft 31 with a gap to realize the upper limit of the roller shaft 31 and ensure the stability of the roller shaft 31 inside the shaft groove.

[0039] In this embodiment, a jacking mechanism 5 is arranged on the outer wall of the vertical plate 2. The jacking mechanism 5 is at least used to take out the winding roller assembly 3 from inside the vertical plate 2.

[0040] Specifically, the jacking mechanism 5 includes a mounting rod 51 arranged on the outer wall of the vertical plate 2. And at the end of the mounting rod 51, there is a jack 52. The jack 52 can be one of a hydraulic cylinder or a screw motor, etc. At the top of the jack 52, there is a lifting rod 53. At the top of the lifting rod 53, there is a bracket 54. After the leather winding is completed by using the winding roller assembly 3, the jack 52 can be started to drive the lifting rod 53 to rise. The bracket 54 at the top of the lifting rod 53 drives the roller shaft 31 to be jacked up, so that the roller shaft 31 is disengaged from the inside of the shaft groove, and the roller shaft 31 enters the inside of the chute 25 and moves from top to bottom along the chute 25, which is convenient to take down the winding roller assembly 3 from the vertical plate 2.

[0041] In this embodiment, a guiding roller 6 and a tensioning roller 8 are arranged in front of the vertical plate 2. The guiding roller 6 and the tensioning roller 8 are at least used for the directional conveying of the leather.

[0042] Specifically, the guiding roller 6 and the tensioning roller 8 have the same structure. The guiding roller 6 includes a shaft rod 61 and a roller sleeve 62. The guiding roller 6 and the tensioning roller 8 are used to guide and convey the leather. The leather first enters from below the tensioning roller 8, passes through above the tensioning roller 8, and finally winds around the roller shaft 31 from above the guiding roller 6.

[0043] In this embodiment, a tensioning assembly 7 is provided inside the vertical plate 2. The tensioning assembly 7 is at least used to support the up and down movement of the tensioning roller 8.

[0044] Specifically, the tensioning assembly 7 includes a compression spring 71, and an extrusion seat 72 is provided at the bottom end of the compression spring 71. When the winding roller assembly 3 is started to move, a pulling force is generated on the leather. The leather drives the tensioning roller 8 to move upward. At this time, the tensioning roller 8 drives the extrusion seat 72 and the compression spring 71 to move upward, realizing the tensioning effect on the leather during winding, and ensuring the flatness and tightness of the leather winding.

[0045] In this embodiment, a driving device 10 and a transmission member 11 are fixedly provided on the outer wall of one side of the vertical plate 2. The driving device 10 is in transmission connection with the transmission member 11. The driving device 10 is a reduction motor, which drives the transmission member 11 to move. A driving gear is provided at the top of the transmission member 11, and the driving gear is used to drive the transmission gear 35 to rotate, thereby realizing the rotational movement of the roller shaft 31 and realizing the winding function of the leather.

[0046] Working principle: The operator first adjusts the width of the winding roller assembly 3 by sliding the shaft sleeve 33 and the retaining piece 32 outside the roller shaft 31.

[0047] Place the winding roller assembly 3 inside the shaft groove to realize the installation of the winding roller assembly 3 on the vertical plate 2.

[0048] Then, lower the limiting frame 4 so that the limiting frame 4 limits the upper part of the winding roller assembly 3, ensuring the stability of the winding roller assembly 3 rotating inside the shaft groove.

[0049] Let the leather first enter from below the tensioning roller 8, pass through above the tensioning roller 8, and finally wind around the roller shaft 31 from above the guiding roller 6.

[0050] Start the winding roller assembly 3 to realize the winding of the leather.

[0051] After the leather winding is completed, loosen the limiting frame 4, start the jacking mechanism 5, and let the winding roller assembly 3 be obliquely ejected from the inside of the shaft groove, so that the winding roller assembly 3 enters the inside of the chute 25 and falls below the chute 25. The shock absorption spring 9 is used for shock absorption to make it fall smoothly, and the winding roller assembly 3 is taken out from the discharge port.

[0052] Only some exemplary embodiments of the present utility model are described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
