Abstract
Description
Technical Field
[0001] This utility model relates to the field of synthetic leather technology, specifically to a rolling device for synthetic leather production. Background Technology
[0002] Synthetic leather, as an important polymer material, is widely used in footwear, bags, automotive interiors, and other fields. In the production process of synthetic leather, the rolling process is one of the key steps. Its function is to use pressure to tightly bond the layers of raw materials, thereby improving the strength, smoothness, and surface texture of the product. Traditional equipment often uses a single fixed mold for rolling, which is difficult to adapt to raw materials of different thicknesses and materials. This can easily lead to uneven local pressure, causing wrinkles, bubbles, or delamination on the product surface. Existing equipment usually requires stopping the machine to change the mold to adapt to different specifications of products. Moreover, the lack of real-time detection and dynamic adjustment functions during the rolling process results in a high scrap rate.

[0062] Instructions for use
[0063] Rollers 4 are rotatably connected to the support column inside the mounting bracket 3 at the top of the support plate 2. Raw material 9 is fitted onto the outside of rollers 4. The rotation of rollers 4 provides power for conveying raw material 9, transporting it from its initial position towards the mold 10. The surface of rollers 4 typically has a certain frictional force to ensure stable movement of the raw material. The rotational speed of the rollers can be adjusted as needed to control the conveying speed of the raw material. The other end of the raw material 9 is fitted onto the outside of the mold 10 and continues to be conveyed forward under the rotation of the mold 10. This cyclical conveying method allows the raw material to continuously pass through the rolling area, achieving continuous production. The interior of the mold 10 is hollow, in which... One end of the mold 10 is rotatably connected to a magnetic roller 15. A motor 16 drives the magnetic roller 15 to rotate. During rotation, the magnetic roller 15 applies pressure and friction to the raw material 9 inside the mold 10. The speed of the motor 16 can be adjusted according to different production needs, thereby changing the rolling speed and pressure of the magnetic roller 15. The other end of the mold 10 is rotatably connected to a magnetic roller 17. An mounting ring 12 is fixedly connected to the outside of the magnetic roller 17. The magnetic roller 17 and the magnetic roller 15 rotate differentially. This differential rotation causes the raw material 9 to be subjected to forces of different directions and magnitudes inside the mold 10. To achieve a more uniform rolling effect, for example, when the magnetic roller 15 rotates clockwise, the magnetic roller 2 17 may rotate counterclockwise at a different speed, performing cross-rolling on the raw material 9. The connecting rod 13 on the cylinder fixedly connected to the outside of the short shaft 14 has its other end fixedly connected to the outside of the mounting ring 12. The connecting rod 13 connects the magnetic roller 15 and the magnetic roller 2 17, making their movements interconnected. When the magnetic roller 15 rotates, the connecting rod 13 drives the magnetic roller 2 17 and the mounting ring 12 to make corresponding movements, further enhancing the cyclicity and uniformity of the rolling. The bottom of the magnetic roller 11 is rotatably connected. Outside the raw material 9 and through the mold 10, the magnetic roller 11 moves according to the trajectory of the mounting ring 12. It is magnetic and can be attracted to the surface of the raw material 9. During the movement of following the mounting ring 12, it assists in rolling the raw material 9. It can adjust the local state of the raw material in real time, such as smoothing out small wrinkles and adjusting the tension of the raw material, thereby further improving the uniformity and quality of rolling. During the rotation of the collecting wheel 8, it collects and sorts the tested synthetic leather products to prepare for subsequent packaging and storage. The rotation speed of the collecting wheel 8 can be adjusted according to the conveying speed of the raw material and the production efficiency to ensure that the products can be collected in an orderly manner.
[0064] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
