Description
Technical Field
[0001] The utility model relates to the field of leather feeding, in particular to a leather flattening device. Background Art
[0002] Leather is a commonly used material in today's society. It is often used in shoemaking, clothing and some daily necessities. During the leather cutting process, since the leather itself is a flexible material, it is impossible to use a rigid robot to grab and load the material. Therefore, manual loading is often used. However, the manual loading method is inefficient, and during the leather loading process, the leather needs to be flattened for subsequent processing. The existing technology usually uses a belt conveyor for transportation. When the leather is placed on top, it cannot be guaranteed that the leather will remain flat during transportation. If the leather is folded after being placed on the conveying device, it will affect subsequent processing. Utility Model Content

[0014] From the above description of the utility model, it can be seen that compared with the prior art, the beneficial effects of the utility model are:
[0015] First, the leather is kept flat by the flattening roller running at a differential speed with the conveying device, and the driving cylinder drives the swing rod to swing.

[0024] The swing rod 50 includes a swinging portion 500 and a flattened portion 501. The swing rod 50 is connected to the support frame 2 via a pin, so that the swinging portion 500 and the flattened portion 501 of the swing rod 50 are respectively located on both sides of the pin, and the driving cylinder 51 is connected to the swinging portion 500 so that the swing rod 50 can rotate around the pin. The length of the flattened portion 501 is greater than that of the swinging portion 500, and an arc-shaped protective surface 502 is formed on the edge of the flattened portion 501.
[0025] The anti-roll mechanism 6 includes an anti-roll rod 60 and a plurality of anti-roll wires 61.
