Blister molding method for anti-static plastic sheet

Abstract

The invention discloses a blister molding method for an anti-static plastic sheet, and belongs to the technical field of plastic sheet blister molding. A plastic sheet body is guided through a pair ofanti-static rollers with static brush layers, and anti-static treatment is performed on the upper end face and the lower end face of the plastic sheet body. After the plastic sheet body is conveyed to a spraying box, anti-static agent powder filling the spraying box is sprayed on the upper end face and the lower end face of the plastic sheet body respectively, a melting box is used for melting ahot melting fiber net just sprayed with the anti-static agent powder, and bonding and forming are conducted to form an anti-static layer. In other words, in the blow molding and conveying process of the plastic sheet body, the situation that potential safety hazards are caused in blow molding production as charges are accumulated on the plastic sheet body due to carrying, contact, friction and other operations in the production process is avoided. After the plastic sheet body is subjected to blow molding fusion, the anti-static layer is embedded in a blow molding product in a fusion mode, andthe anti-static performance of the blow molding product in the subsequent using process is effectively achieved.

Description

technical field [0001] The invention relates to the technical field of plastic sheet blister molding, and more specifically, relates to a process method of antistatic plastic sheet blister molding. Background technique [0002] Blister molding is one of the thermoforming methods of thermoplastics. It refers to clamping sheet or plate materials on the frame of the vacuum forming machine. After heating and softening, it passes through the air channel on the edge of the mold and absorbs it on the mold with vacuum. , after a short period of cooling, a molded plastic product is obtained. The equipment used in this method has the advantages that the mold does not need to bear high pressure, the molding speed is fast, and the operation is easy. The large-scale production scale makes the use of plastic more and more frequent, and the scope of application is also wider and wider, such as beverage bottles, Packing boxes, etc., the quality of plastic molding directly affects the use o...

Problems solved by technology

[0003] Plastic materials are blow-molded and processed to make plastic semi-finished products or finished products. Since most plastic materials are small good conductors and have good insulation properties, they are very easy to be damaged during the production process due to handling, contact, separation, friction, Static electricity is generated by collisions, interference in electromagnetic induction occasions, etc., and stays on the surface of the object for a long time, causing electrostatic hazards after accumulating to a certain static voltage value. When plastic sheets with electrostatic hazards are blown, there will be safety hazards. Hidden danger
