Description

Technical Field

[0001] The invention relates to the technical field of leather processing, in particular to a method for making automobile interior leather. Background Art

[0002] Automotive interior leather refers to leather materials used for automotive interior decoration. These materials are usually used in seats, steering wheels, door panels, instrument panels and other parts to provide passengers with a comfortable riding experience and luxurious visual experience. During its production process, it often needs to undergo multi-layer composite treatment, the purpose of this process is to make the leather more breathable and waterproof. Through this composite technology, the shortcomings of leather can be significantly improved, thereby improving the overall performance of leather in many aspects.

[0003] However, due to the softness of leather, heat pressing can easily lead to leather accumulation. This accumulation will further cause wrinkles on the leather surface, and these wrinkles will be pressed on the leather surface during the heat pressing process, forming defects that are difficult to eliminate. These defects not only seriously affect the performance of automotive interior leather, but also have a negative impact on the quality of automotive interior leather. Summary of the invention

[0006] Through the above technical solution, a connecting plate and a first spring are set, and a motor drives a rotating wheel to rotate and contract the steel wire, and a connecting plate is passed through one side of the steel wire. When the connecting plate pulls the spring, the two layers of leather are kept in a taut state through the first spring due to the different lengths of the two layers of leather clips. There are no wrinkles on the surface of the leather, and wrinkle marks are avoided when passing through hot pressing.

[0008] Through the above technical solution, a slide groove is set to allow the connecting plate to slide from the surface of the movable plate on the lower pressure plate to prevent the connecting plate or multiple fixed clips from being unbalanced and unable to keep the leather pulled horizontally, which may easily cause wrinkles. A movable handle is set to facilitate employees to move the connecting plate and prevent hands from being extended under the upper pressure plate to cause safety hazards.

[0009] The present invention is further configured such that a second spring is provided on the inner side of the upper movable clamp, the lower movable clamp, the upper fixed clamp and the lower fixed clamp; the upper end of the second spring is slidably connected to a small pressure plate; the second spring is slidably connected to a control clamp on the side away from the small pressure plate; the middle part of the control clamp is rotatably connected to the inner wall of the upper movable clamp, the lower movable clamp, the upper fixed clamp or the lower fixed clamp.

[0010] Through the above technical solution, a second spring is provided to facilitate the small pressure plate to automatically press down to fix the leather, and a control clip is provided. The control clip rotates and moves to lift the upper side of the second spring, allowing the small pressure plate to move up to open the fixing clip, so as to facilitate manual opening of the lower pressure plate at each position to move up, thereby fixing or removing the leather.

[0016] Through the above technical solution, a third spring and a lower pressure plate are set. When the upper pressure plate is pressed down, the upper movable clamp and the connecting plate are pressed, and the spring is combined to lower them to prevent the upper pressure plate from being unable to perform high-temperature gluing on the leather. When the movable plate is pressed down, the leather is further pulled to prevent wrinkles.

[0017] The beneficial effects of the present invention are as follows: 1. The present invention provides a connecting plate and a first spring, and drives a motor to drive a rotating wheel to rotate and shrink a steel wire, and passes through a connecting plate on one side of the steel wire. When the connecting plate pulls the spring, the two layers of leather are kept in a taut state through the first spring due to the different lengths of the two layers of leather clips. There is no wrinkle on the surface of the leather, and wrinkle marks are avoided when passing through hot pressing; 2. The present invention provides a sliding groove to allow the connecting plate to slide on the lower pressing plate from the surface of the movable plate, thereby preventing the connecting plate or multiple fixing clips from being unbalanced and unable to keep the leather pulled horizontally, which may easily lead to wrinkles. A moving handle is provided to facilitate employees to move the connecting plate, thereby preventing hands from being extended under the upper pressing plate to cause safety hazards. 3.
