[0001] The utility model relates to the technical field of leather processing, and particularly relates to a grain embossing machine. Background Technique

[0002] At present, manufacturers of artificial leather and synthetic leather soak the synthetic leather in water and then emboss the surface of the synthetic leather in order to better simulate the surface of natural leather. Embossing is an essential process in the final stage of synthetic leather processing. By repeatedly embossing the synthetic leather, the leather becomes soft and elastic, which can promote the formation of a texture similar to that of natural leather on its surface, soften the surface texture of the synthetic leather and improve the glossiness. It is an important link in determining the quality of synthetic leather products.

[0003] The embossing process is mainly realized by an embossing machine. The formed synthetic leather is loaded into the drum of the embossing machine, and the temperature inside the drum is heated to a high temperature through a heat pipe for drying the synthetic leather. And the embossing effect is achieved by the rotation of the drum at high temperature. However, a large amount of hot air is discharged to the outside during the working process of the existing embossing machine, and the internal waste heat of the existing embossing machine is not fully utilized, thus easily causing waste of resources. Content of the Utility Model

[0004] The purpose of the utility model is to provide an embossing machine to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] An embossing machine, comprising:

[0007] An embossing mechanism capable of processing the surface of leather into a textured shape, and the embossing mechanism comprises a box body; [[ID=​​​​Furthermore, a closing plate is rotatably connected to the outer wall of the box body. A glass plate is fixedly connected to the center position of the closing plate. A fixing block is fixedly connected to the side wall of the box body, and a locking column inserted into the closing plate is screwed into the fixing block.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By putting the leather into the kneading cylinder, then rotating to close the closing plate, screwing the locking column to connect the fixing block and the closing plate, driving the kneading cylinder to rotate through the output end of the driving motor, arranging an annular groove on the sleeve at the end of the kneading cylinder, and rolling the limiting wheel in the annular groove, the rolling friction force of the kneading cylinder can be reduced, so that the kneading cylinder can perform rolling and tumbling kneading on the leather inside, forming texture on the leather surface. Then, close the solenoid valve I and the solenoid valve III and open the solenoid valve II, and heat the inside of the box body through the heating pipe in the heating box, so that the leather can be heated during the kneading process. The air with residual temperature at the bottom of the box body can be pumped by the L-shaped pipe at the output end of the air delivery pump into the C-shaped pipe, and then discharged into the box body again after heating, so as to facilitate the recycling of the dried hot air and reduce the waste of effective resources.

Filter the impurities in the air sucked from the outside through the air filter element in the filter cartridge, then transport the cold air from the outside to the cavity plate through the U-shaped pipe, and then quickly cool the embossing cylinder and the leather in it through multiple exhaust columns at the bottom of the cavity plate.
