Winding roller placing method for degradable polymer film

Abstract

The invention discloses a winding roller placing method for a degradable polymer film. In the first step, placing equipment comprises a treatment box and a support fixedly mounted at the bottom of the treatment box, the support is provided with an upper roller mechanism, the treatment box is internally provided with a positioning mechanism, the outer surface of the treatment box is provided with an anti-wrinkling mechanism, the upper roller mechanism comprises a driving motor, a first air cylinder and a limiting box. According to the winding roller placing method for the degradable polymer film, the upper roller mechanism and an angle limiting unit are arranged, a driving motor is used for driving a driving rotating shaft to rotate, a lifting rotating shaft rotates along with the driving rotating shaft, a first air cylinder is matched to drive the limiting box to move, and the rotation between an arc plate and a first limiting plate and the rotation between the arc plate and a second limiting plate are matched; and automatic feeding of a winding roller is achieved, the rotating angle can be well limited, more accurate positioning and placing are achieved, and therefore the efficiency of film winding is improved.

Description

technical field [0001] The invention relates to the technical field of film processing, in particular to a winding roller placement method for degradable polymer films. Background technique [0002] Degradable films not only have the functions and characteristics of traditional plastics, but also can be split and degraded in the natural environment through the action of microorganisms in soil and water or ultraviolet rays in sunlight after reaching the end of their service life, and finally re-enter the ecology in a reduced form. In the environment, return to nature; domestically developed varieties have covered photodegradation, photobiodegradation, photooxidative biodegradation, high starch content biodegradation, high calcium carbonate filled photooxygen degradation, full biodegradation, etc.; the most commonly used It is an edible film and a water-soluble film. [0003] Referring to the Chinese patent, the patent name is: a method for preparing and winding plastic film ...

AI Technical Summary

Problems solved by technology

[0008] Aiming at the deficiencies of the prior art, the present invention provides a winding roller placement method for degradable polymer films, which solves the problem that the winding rollers will be placed when the existing winding equipment replaces the winding rollers. If it is not in place, it will cause the problem of left and right movement and rotation in the subsequent winding, which will lead to the deviation of the film winding. At the same time, there will be insufficient film tension during the winding process, which will cause wrinkles in the subsequent winding film.
