Embossed wheel

Abstract

The present invention relates to forming machine technology, and is especially one embossing roller for forming pattern in the surface of artificial leather, plastic product, etc. The embossing roller includes one metal roller and one air permeable embossing roller outside the metal roller, the hollow metal roller has one cavity to form one cooling chamber with water inlet and water outlet as well as axial holes in the outer wall and communicated to radial holes to the outer surface of the metal roller, and the axial holes and the radial holes constitute one air pumping passage for the embossing roller to operate in negative pressure state. The embossing roller has optimized structure, simplified cooling system, low cost, and easy installation and use.

[0002] After the processing of artificial leather or plastic products, various patterns are generally formed on the surface to increase the beauty of the surface, and various products are produced to attract consumers' desire to buy; or various patterns are formed on the surface to increase Anti-friction and other industrial purposes, and the working principle of various plastic body surface pattern forming devices is to use the form of rubber roller and embossing roller to roll out the required pattern on the surface of the plastic to be formed, that is, the positive The embossing method is to roll and form various required patterns on the surface of the drum. In order to ensure the normal operation of the embossing roller at a lower temperature, it is necessary to set a cooling channel on the embossing roller. The existing embossing roller Not only the manufacturing process is complicated, but also the cost is high, which cannot meet the needs of production, and in the process of production and processing, it often happens that when the thickness of the processed plastic product is lower than a certain size (such as less than 0.2mm), the rubber roller and the embossing roller will be damaged. Patterns cannot be formed on its surface. The reason is due to the distance between the rubber roller and the embossing roller and the pattern formed on the surface of the embossing roller, which brings a lot of inconvenience to the production plant.
