[0004] The technical solution adopted by the utility model to solve its technical problems: This kind of grain-embossing device for synthetic leather processing includes a machine case and a grain-embossing roller. The grain-embossing roller is installed inside the machine case. A support platform is fixedly connected to the back of the machine case. A driving motor is installed on the top of the support platform. A rotating shaft is arranged at the output end of the driving motor.

A second transmission roller is installed inside the machine case. A third transmission roller is installed inside the machine case. An outlet is opened on the side of the machine case. The synthetic leather reaches inside the machine case through the inlet, and successively passes through the first transmission roller, the second transmission roller, multiple inner covers, multiple grain-embossing rollers, the third transmission roller and the outlet. The synthetic leather passes through the inside of the machine case, reaches inside the machine case through the inlet, and leaves the inside of the machine case through the outlet. The first transmission roller, the second transmission roller and the third transmission roller assist in the transmission of the synthetic leather. At the same time, the first transmission roller, the second transmission roller and the third transmission roller limit the transmission path of the synthetic leather, making it convenient for the synthetic leather to pass between multiple grain-embossing rollers and multiple inner covers. When the synthetic leather stops transmitting inside the machine case, multiple driving motors run forward and backward repeatedly. The rotating shaft drives the first connecting shaft and the grain-embossing roller. Multiple grain-embossing rollers rotate repeatedly in a small amplitude clockwise and counterclockwise. Multiple first convex columns and multiple second convex columns contact the upper and lower surfaces of the synthetic leather and perform the grain-embossing function. After the grain-embossing treatment of one section of the synthetic leather is completed, the synthetic leather continues to be transmitted. When it reaches a suitable position, the synthetic leather stops transmitting and then undergoes the subsequent grain-embossing treatment, increasing the acting area and improving the grain-embossing effect. The operation is simple and easy to use, saving time and improving the operation efficiency.

The two second hydraulic cylinders stop, and an effective isolation is formed between the inside and the outside of the machine case, reducing the influence of the outside on the inside of the machine case. When the second hydraulic cylinder contracts and operates, it drives the sealing plate to move upward in the internal hole, and the opening is opened. The operation is simple and convenient to use.
[0011] Further improvement: The bracket is of an L-shaped structure. There are two second hydraulic cylinders. The two second hydraulic cylinders operate simultaneously, improving the operation efficiency of the sealing plate and increasing the stability of the sealing plate during the up and down movement.
[0012] The beneficial effects of the present utility model are:
[0013] 1. The synthetic leather passes through the inside of the chassis, enters the inside of the chassis through the inlet, and leaves the inside of the chassis through the outlet. The first driving roller, the second driving roller and the third driving roller assist in the conveyance of the synthetic leather. At the same time, the first driving roller, the second driving roller and the third driving roller limit the conveyance path of the synthetic leather, enabling the synthetic leather to easily pass between multiple creasing rollers and multiple inner covers.

The operation is simple and easy to use, saving time and improving the operation efficiency.
[0014] 2. The first rounded corner and the second rounded corner effectively protect the surface of the synthetic leather, increasing safety and preventing scratching of the synthetic leather, avoiding damage to the product during the processing. The third rounded corner increases the smoothness, facilitating the efficient passage of the synthetic leather, and further improving safety at the same time.
[0015] 3. When the second hydraulic cylinder extends and runs, it drives the sealing plate to move downward in the built-in hole. Finally, the sealing plate reaches the inside of the built-in groove, and the sealing plate closes the opening. The two second hydraulic cylinders stop, forming an effective isolation between the inside and the outside of the chassis, reducing the influence of the outside on the inside of the chassis. When the second hydraulic cylinder contracts and runs, it drives the sealing plate to move upward in the built-in hole, and the opening is opened. The operation is simple and convenient to apply. The two second hydraulic cylinders run simultaneously, improving the running efficiency of the sealing plate and increasing the stability of the sealing plate during the up and down movement at the same time.
