One-time-molding synthetic film production line and connection structure thereof

Abstract

The invention discloses a one-time-molding synthetic film production line and a connection structure for the one-time-molding synthetic film production line. The one-time-molding synthetic film production line and the connection structure for the one-time-molding synthetic film production line are characterized by comprising a closed refining machine, a casting film machine, a primary thickness detection machine, a stretcher, a secondary thickness detection machine, a point pressing machine, a corona machine and a winder, wherein primary thickness detection machine is butted to the material outlet of the casting film machine and used for performing primary thickness detection on a synthetic film, the stretcher is butted to the material outlet of the primary thickness detection machine andused for performing stretching operations on the synthetic film, the point pressing machine is butted to the material outlet of the stretcher and used for performing point pressing operations on the synthetic film, the corona machine is butted to the material outlet of the point pressing machine and used for performing corona treatment on the synthetic film, and the winder is butted to the material outlet of the corona machine and used for winding the synthetic film. By means of the production line, production-line one-time-molding operations are combined, multiple intermediate links are omitted, the synthetic film molding smoothness is extremely high, the production efficiency is improved by a large margin, and the finished product quality of the synthetic film is high.

Description

technical field [0001] The invention relates to the field of synthetic film manufacturing, in particular to a one-shot synthetic film production line and its connecting structure. Background technique [0002] The equipment required in the traditional synthetic membrane manufacturing process such as Figure 4 As shown, it mainly includes internal mixer a and casting machine c. The film-making raw materials such as resin are quantitatively transported into internal mixer a through vacuum. Internal mixer a contains twin-screw extruder b, twin-screw extruder The extruder b extrudes the raw material into the casting machine c, and the casting machine c performs subsequent film making. [0003] Among them, also as Figure 4 As shown, the front end of the tape casting machine c is provided with two horizontally arranged rolling cylinders d, the cylinder surfaces of the two rolling cylinders d are close to each other with a certain extrusion gap left between them, twin-screw extrus...

AI Technical Summary

Problems solved by technology

[0004] Different batches and different types of films have different viscosities of the raw materials produced. Since there is a certain distance between the outlet of the twin-screw extruder b and the roller d, if the flow rate of the extruded film raw materials becomes larger, Situations where raw material splashes are likely to occur
