Transparent polyvinyl chloride film calendaring forming device

Abstract

The invention discloses a transparent polyvinyl chloride film calendaring forming device which comprises a box body. The box body is in a right triangle shape, a feeding port is formed in the upper end of the side wall of the vertical side of the box body, a discharging port is formed in the lower end of the side wall of the inclined side of the box body, an overhaul window is arranged on the surface of the side wall of the inclined side of the box body, and a box cover is arranged above the overhaul window; and a first calendering roller, a second calendering roller, a third calendering roller and a fourth calendering roller are arranged in the box body, the first calendering roller is fixedly installed on the inner wall, close to the feeding port, of the box body, fixing frames are symmetrically and fixedly installed on the inner wall of the box body, the fixing frames are obliquely arranged, the second calendering roller, the third calendering roller and the fourth calendering roller are sequentially installed on the fixing frames from top to bottom, the second calendering roller and the fourth calendering roller are slidably connected with the fixing frames, and a guide roller is fixedly installed at the lower end of each fixing frame. According to the device, dust can be prevented from adhering to a film during working, the yield of a polyvinyl chloride film finished product is increased, and meanwhile, the distance between the calendering rollers can be accurately adjusted, so that the thickness of the polyvinyl chloride film is accurately controlled.

Description

technical field [0001] The invention relates to the field of polyvinyl chloride film production, in particular to a transparent polyvinyl chloride film calendering molding device. Background technique [0002] With the continuous development of many modern industries, polyvinyl chloride (PVC) films are now widely used. Due to the addition of plasticizers, anti-aging agents and other toxic auxiliary materials in the manufacturing process to enhance their heat resistance, PVC films It is very popular in many industries nowadays, and it is the most widely used synthetic material. Because soft PVC contains a softener (this is also the difference between soft PVC and hard PVC), it is easy to become brittle and difficult to store, so its application range was limited. Rigid PVC does not contain softeners, so it has good flexibility, easy to form, not brittle, non-toxic and pollution-free, and has a long storage time, so it has great development and application value. Soft PVC is...

Problems solved by technology

The calender rolls are exposed to the air during the calendering of the existing vinyl chloride film, and the dust in the air will adhere to the film surface during calendering, affecting the transparency of the film. At the same time, the distance between the calender rolls of the existing calender is mostly adjusted manually It is difficult to precisely control the thickness of the film after molding
