Vacuum embossing roll

Abstract

A vacuumizing-embossing drum for generating pattern on the surface of plastic product is composed of a hollow metallic drum with air pinholes and water tubes on its wall, which are respectively linked with the rotary vacuumizing jointer and rotary water jointer on the end face of said drum, and a leather jacket on said drum and with needed pattern on its external surface.

Description

Technical field: [0001] The invention relates to the technical field of forming patterns on the surface of plastic products, in particular to a vacuum embossing wheel. Background technique: [0002] Ordinary plastic products are processed with various patterns on the surface, such as animal skin patterns, wood patterns, artificial or computer-designed patterns, etc., to increase the beauty of the product and the variety of colors, attracting people Of course, sometimes adding different patterns is to produce different friction or wear resistance and other product application properties, and the processing principles of various patterns formed on various plastic materials are based on rubber A concave mold made of rubber material is set on the roller, and it is cured to form a concave plate pattern. However, there are common problems in the existing embossing equipment: one is to form a rubber roller with an embossed pattern. After being used for a period of time, it will be...

Problems solved by technology

[0002] Ordinary plastic products are processed with various patterns on the surface, such as animal skin patterns, wood patterns, artificial or computer-designed patterns, etc., to increase the beauty of the product and the variety of colors, attracting people Of course, sometimes adding different patterns is to produce different friction or wear resistance and other product application properties, and the processing principles of various patterns formed on various plastic materials are based on rubber A concave mold made of rubber material is set on the roller, and it is cured to form a concave plate pattern. However, there are common problems in the existing embossing equipment: one is to form a rubber roller with an embossed pattern. After being used for a period of time, it will be damaged due to wear or fatigue, and when the leather case and the wheel body are integrated, the entire embossing wheel will be scrapped; A pattern is formed on the product, and the pattern needs to be made on one or several embossing wheels. An enterprise needs many kinds of embossing patterns, so it needs to make many kinds of embossing wheels and store them in the warehouse for selection during use, resulting in The inventory site is large and the production cost is high; the third is that the working temperature is difficult to control: as the equipment runs longer, the ambient temperature near the embossing wheel also increases, and the optimum embossing temperature for plastic products has a certain range If it exceeds the range, the molded pattern will be deformed, resulting in defective or waste products. In order to ensure product quality, it is necessary to reduce the production speed in order to reduce the ambient temperature near the embossing wheel and keep the embossing temperature of plastic products at the best Within the temperature range, this will inevitably reduce the production speed of the product and increase the production cost
