Abstract

The invention relates to a single-point and double-point switching type BOPET thin film processing device and method, and belongs to the technical field of plastic thin film processing. The single-point and double-point switching type BOPET thin film processing device comprises a pre-heating unit, a stretching unit, a shaping unit, a transverse cutting unit and tension detection units, wherein the stretching unit is used for heating a base film to a stretching temperature and is composed of an air cylinder I, compression rollers I and pre-heating rollers; the temperature range of the pre-heating rollers is 70-140 DEG C; the stretching unit comprises four stretching rollers, a reflection plate and three infrared heaters; the single-point and double-point switching is realized by the matching of the stretching rollers, the reflection plate and the infrared heaters; the transverse cutting unit is arranged under the shaping unit; the tension detection units used for regulating and controlling tension in the stretching process are arranged under the transverse cutting unit. The single-point and double-point switching type BOPET thin film processing device and method are applied to the production of a BOPET thin film and have the advantages of high processing efficiency, complete functions and the like.

Description

technical field [0001] The invention relates to a single-double-point switchable BOPET film processing device and method, belonging to the technical field of plastic film processing. Background technique [0002] Biaxially oriented polyester film, also known as BOPET film, is widely used in packaging work in various fields due to its good characteristics. Conventional processing devices usually can only achieve single-point stretching or double-point stretching. This device is highly targeted, but its defects are also obvious. First, each device can only produce one specification of film, and the function of the device is Single, the utilization rate is low, and the enterprise must purchase two types of processing devices to realize production if it wants to produce products of thick film and thin film at the same time, and the processing cost is high; , due to the high temperature on the preheating roller and the stretching roller, the film is easily bonded to the preheati...
