A device for treating plastic film wrinkles by using airflow

Abstract

The invention relates to the field of plastic film making, in particular to a device for treating plastic film corrugation by means of airflow. The device comprises a pretreatment air rod, an after-treatment air rod, a corrugation smoothing roller, an airflow supplement fork and a rack, air taps are arranged at the bottom of the pretreatment air rod, the left group of the air taps are arranged to be inclined to the left, and the right group of the air taps are arranged to be inclined to the right; the structure of the after-treatment air rod is the same as that of the pretreatment air rod; the corrugation smoothing roller is located between the pretreatment air rod and the after-treatment air rod, and the corrugation smoothing roller comprises an air blowing cylinder and an air dispersing cylinder; a strip-shaped air dispersing belt is arranged on the side wall of the air dispersing cylinder, the air dispersing cylinder blows air into the air dispersing cylinder to enable the air dispersing cylinder to produce the air flow flowing outwards; the airflow supplement fork arranged on the middle-lower portion of the corrugation smoothing roller in a surrounding mode, and the airflow supplement fork produces upward airflow below the corrugation smoothing roller. According to the device for treating the plastic film corrugation by means of the airflow, the plastic film is blown and smoothed through the airflow before being rolled, and therefore the purpose of blowing corrugation to be flat is achieved.

Description

technical field [0001] The invention relates to the field of plastic film manufacturing, in particular to a device for treating plastic film wrinkles by using airflow. Background technique [0002] In the film manufacturing process of the blown film machine, the film generally needs to pass through many driving rollers on the blown film machine, and finally rolled into the take-up roller. When the film passes through the complex transmission roller, because of the manufacturing and installation accuracy of the roller, the air circulation, the rotation speed of the roller, etc., the film will often appear wrinkled after being involved in the winding roller, which will affect the film on the one hand. Beautiful, and then influence sales, on the other hand can bring inconvenience to the processing and manufacture of follow-up plastic film products, even affect the quality of follow-up products. Therefore, need badly a kind of equipment that can solve the film wrinkle problem o...

Problems solved by technology

When the film passes through the complex transmission roller, due to the manufacturing and installation accuracy of the roller, the air circulation, the rotation speed of the roller, etc., the film will often appear wrinkled after being involved in the winding roller, which will affect the film on the one hand. Beautiful, which in turn affects sales. On the other hand, it will bring inconvenience to the processing and production of subsequent plastic film products, and even affect the quality of subsequent products.
