A roll film tension adjustment device

Abstract

The invention discloses a winding film tension adjustment device. The winding film tension adjustment device is characterized by comprising a base rod, a movable plate mounting part, multiple movable plates, a pressing plate and a knob handle, wherein a retainer ring is arranged on the peripheral surface of the base rod; the movable plate mounting part coats the base rod; the multiple movable plates are arranged in the movable plate mounting part; one end of each movable plate can extend out from the other end, corresponding to the retainer ring, of the movable plate mounting part; meanwhile, the other end of each movable plate can extend out from the side surface of the movable plate mounting part; the pressing plate can be butted against one ends of the multiple movable plates; and a thread rod is arranged at one end of the knob handle, penetrates through the pressing plate, and is in threaded connection with the base rod. The winding film tension adjustment device can effectively simplify the structure, improves the tension adjustment convenience and the tension stability to adapt to different tension demands, and guarantees the packing quality of winding films.

Description

technical field [0001] The invention relates to the technical field of packaging equipment, in particular to a roll film tension adjusting device. Background technique [0002] In the packaging equipment using strip-shaped film materials, the roll film is released from the unwinding mechanism, passes through several intermediate rollers, and then is output to the material equipment. In actual operation, if the roll film before the material equipment is loose, on the one hand, it will affect the flatness of the roll film, which will affect the processing quality of subsequent processing; on the other hand, for the roll film output in multiple rows, it will Make a certain difference in the amount of material used in multi-row material equipment, thus affecting the consistency of product quality. Therefore, it is usually necessary to install a roll film tensioning device before the material equipment, so that the roll film is in a tensioned state under the action of a suitable...

AI Technical Summary

Problems solved by technology

The existing roll film tensioning device usually uses spring as the tension generating part, but the tension of this spring-powered tensioning device is difficult to adjust, and cannot adapt to the tension change requirements of different materials and different process requirements; at the same time, the spring component is After a long time of use, its elasticity will also change, which will affect the quality of the product
