Problems solved by technology

[0003] At present, when producing PVC film, one of the processes is to manually transport the masterbatch to the inside of the extruder, so as to perform extrusion blow molding on the film raw material, but the existing feeding device does not have a It is impossible to accurately know how many masterbatches produce how many PVC films, and because most of the films have different thicknesses, the required masterbatch weights are also different. Therefore, we propose a special Production equipment and production process of thin PVC film

Abstract

The invention discloses a production device and a production process of an ultra-thin PVC film, relates to the technical field of PVC film production, and solves the problem that quantitative feeding cannot be carried out. The production device comprises a bottom plate, a box body, a Y-shaped rod and a material box, wherein a plastic extruding machine is arranged on one side of the material box, the box body is fixed to the top part of the bottom plate, the Y-shaped rod is connected to the top part of the box body in a sliding mode, the top end of the Y-shaped rod makes contact with the bottom part of the material box, racks are fixed to the two sides of the Y-shaped rod correspondingly, and gears are meshed with the two racks correspondingly. Through mutual cooperation of the Y-shaped rod, the racks, the gears, a first rotating shaft and a first triggering assembly, in the process of injecting raw materials into the material box, the material box can drive the Y-shaped rod to slowly move downwards, and a first trigger switch is driven to start a lifting assembly to operate. Therefore, the master batch can be accurately quantified, and the quantity of PVC films produced by using the master batch can be accurately known.

Description

technical field [0001] The invention relates to the technical field of PVC film production, in particular to a production device and a production process for an ultra-thin PVC film. Background technique [0002] The main component of PVC film is polyvinyl chloride, and other components are added to enhance its heat resistance, toughness, and ductility. The top layer of this surface film is paint, the main component in the middle is polyvinyl chloride, and the bottom layer is a back coating adhesive. It is a well-loved, popular and widely used synthetic material in the world today. The global usage of PVC film is the second highest among all synthetic materials. Among the materials that can produce three-dimensional surface films, PVC is the most suitable material, [0003] At present, in the production of PVC film, one of the processes is to manually transport the master batch to the inside of the extruder, so as to extrude and blow the film raw material, but the existing...
