Description

Technical Field

[0001] This utility model relates to the field of leather product processing technology, specifically a wrinkle removal device for leather product processing and production. Background Technology

[0002] Leather is animal hide that has been modified and is not easily perishable through physical and chemical processing such as hair removal and tanning. After processing, in order to improve the appearance and smoothness of leather products, it is necessary to remove wrinkles from the leather surface.

[0003] According to publication number CN216919292U, a flattening device for removing wrinkles from automotive leather products is first placed on a level surface. Then, the various components within the device are checked for damage. After ensuring there is no damage, the power is turned on. The side edge of the automotive leather product is then placed on the pressure-resistant anti-slip strip. Subsequently, the first electric push rod shortens, causing the pressing block to move downwards and press down on the side edge of the leather product. Then, the motor starts, driving the lead screw to rotate. The nut seat on the lead screw then drives the flattening bracket to move linearly. At the same time, the second electric push rod shortens, causing the flattening bracket to move downwards. The smooth contact layer contacts and presses against the leather product, flattening the wrinkled parts. This method is very convenient as it eliminates the need for staff to walk back and forth to smooth the wrinkles.

[0004] The smooth contact layer and other structures mentioned above can be used to flatten and remove wrinkles from leather products. However, since leather products are composed of tightly interwoven collagen fibers, they are relatively hard and have poor elasticity at room temperature, making it difficult for the flattening support to stretch them during wrinkle removal, thus reducing the wrinkle removal effect.
