DETAILED DESCRIPTION

[0022] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Example 1

[0024] Reference Figs. 1-2 A leather punching machine, comprising a rack 1, a pressing unit 2, and a punching unit 3 and a telescopic unit 4 connected to the rack 1. The rack 1 is provided with a base plate 11 for placing leather, and multiple telescopic units 4 are distributed around the base plate 11. The pressing unit 2 is connected to the free end of the telescopic unit 4. The telescopic unit 4 is used to move the pressing unit 2 to the edge of the leather. The pressing unit 2 is used to press the edge of the leather.

[0025] In the embodiment, the telescopic units 4 are slidably connected to the rack 1, and the number of the telescopic units 4 is multiple. The specific working process of the leather punching machine is as follows: the worker places the leather on the base plate 11, moves one telescopic unit 4 to a straight line at the position required to press the leather, and then stretches the telescopic unit 4 to make the pressing unit 2 position the edge of the leather, drives the pressing unit 2 to work, and makes the pressing unit 2 press the edge of the leather. The same method is used to move other telescopic units 4, so that each edge of the leather is fixed. In this way, leathers of different sizes or shapes can be fixed, and the versatility of the punching machine is improved.

[0026] It should be noted that the telescopic units 4 are slidably connected to the rack 1, and the number of the telescopic units 4 is multiple. The punching unit 3 is a prior art, and the hydraulic oil cylinder and punch structure in CN201920626604 can be referred to for details.

[0027] Preferably, the rack 1 is provided with a sliding boss 12; the sliding boss 12 is provided with a sliding groove 13; the telescopic unit 4 is provided with a sliding block 41; and the sliding groove 13 and the sliding block 41 are in sliding cooperation to enable the telescopic unit 4 to slide on the rack 1.

[0028] In the embodiment, the four sliding bosses 12 are distributed around the base plate 11. The sliding block 41 is pushed into the sliding groove 13, and the telescopic unit 4 is connected to the top of the sliding block 41, so that the telescopic unit 4 drives the sliding block 41 to slide in the sliding groove 13, enabling the telescopic unit 4 to move linearly on the rack 1.

[0029] Preferably, the sliding block 41 is provided with a locking module 42; and the locking module 42 is used to limit the movement of the sliding block 41 on the sliding groove 13.

[0030] In the embodiment, when the telescopic unit 4 moves to the target position, the locking module 42 is tightened, so that the telescopic unit 4 can be temporarily fixed at the position, avoiding displacement of the telescopic unit 4 when the leather is replaced and the need for re-adjustment.

[0031] Preferably, the sliding groove 13 is a T-shaped groove; the shape of the sliding block 41 matches the sliding groove 13; and both sides of the sliding groove 13 are open sides.

[0032] In the embodiment, the sliding groove 13 is a T-shaped groove, the sliding block 41 is T-shaped, and the T-shaped groove sliding mode is adopted to avoid rotation of the sliding block 41 during sliding and ensure smooth sliding of the sliding block 41. In addition, the two sides of the sliding groove 13 are open sides, and the staff can push the sliding block 41 in or out from the two sides to increase or decrease the telescopic unit 4 and the pressing unit 2. When the shape of the leather is more complex, more pressing units 2 are needed to press the different edges of the leather, and when the shape of the leather is relatively simple, only a small number of pressing units 2 are needed for pressing. By setting the two sides of the sliding groove 13 as open sides, the number of telescopic units 4 and pressing units 2 can be more flexibly changed.

[0033] Preferably, the telescopic unit 4 is a telescopic sleeve, the locking module 42 is a handle screw, the telescopic unit 4 is provided with a fixed sheet 43 on both sides, the fixed sheet 43 is provided with a through hole 44, and the locking module 42 is threadedly connected with the sliding block 41 through the through hole 44.

[0034] The mechanism of the telescopic sleeve can refer to CN202321836102, and the shape of the sleeve is square or rectangular. In the embodiment, the shape of the sleeve is preferably rectangular, and the number of sections of the sleeve is three. The number of sections of the sleeve can also be set according to actual needs. Except for the smallest section of the sleeve, each section of the sleeve is provided with a key-shaped hand screw for fixing the extension length of the sleeve.

[0035] The locking module 42 is threadedly connected with the sliding block 41 through the through hole 44. When the telescopic unit 4 moves to the target position, the locking module 42 is twisted to move the sliding block 41 upward, so that the sliding block 41 abuts against the inner wall of the sliding groove 13, thereby limiting the movement of the telescopic unit 4.

[0036] Preferably, the pressing unit 2 comprises a driving module 21 and a pressing plate 22, the driving module 21 is connected to the free end of the telescopic unit 4, and the pressing plate 22 is connected to the power output end of the driving module 21.

[0037] In the embodiment, the driving module 21 is a pneumatic cylinder, the driving module 21 drives the pressing plate 22 to move downward, so that the pressing plate 22 presses the edge of the leather.

[0038] More preferably, a master switch capable of controlling the operation of all driving modules 21 and a plurality of sub-switches capable of separately controlling one driving module 21 are arranged. When fixing the first leather of the same shape, the staff controls the different edges of the leather by the sub-switches. When the same shape of leather needs to be replaced for punching, only the master switch is needed to control all the driving modules 21 to press down or rise, thereby reducing the labor intensity of the staff.

[0039] Preferably, the bottom of the pressing plate 22 is provided with a non-slip pad. The non-slip pad can not only avoid the leather from sliding, but also provide a buffer for the leather, so as to avoid damage to the leather caused by excessive pressure of the pressing plate 22.

[0040] Preferably, the driving unit 5 is further included; the driving unit 5 is used to drive the punching unit 3 to move to a position required for punching the leather.

[0041] In the embodiment, the driving unit 5 can drive the punching unit 3 to move to different positions of the leather for punching.

[0042] Preferably, the driving unit 5 includes a transverse moving module 51, a longitudinal moving module 52 and a moving frame 53; the punching unit 3 is slidably connected to the moving frame 53; the transverse moving module 51 is connected to the moving frame 53; the transverse moving module 51 is used to drive the punching unit 3 to move left and right; the moving frame 53 is slidably connected to the longitudinal moving module 52; and the longitudinal moving module 52 is connected to the rack 1.

[0043] In the embodiment, the transverse moving module 51 and the longitudinal moving module 52 are both lead screw motors; the longitudinal moving module 52 is used to drive the moving frame 53 to move forward and backward, so as to drive the punching unit 3 to move forward and backward; the transverse moving module 51 drives the punching unit 3 to move left and right; by arranging the transverse moving module 51 and the longitudinal moving module 52, the punching unit 3 can be punched at different positions of the leather.

[0044] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and purposes of the utility model, and the scope of the utility model is defined by the claims and their equivalents.
