Description

Technical Field

[0001] The utility model specifically relates to the technical field of tension adjustment for cling film winding, in particular to a tension adjustment device for cling film processing and winding. Background Art

[0002] During the processing of the cling film, it needs to be rolled up. During the rolling process, due to the different transmission speeds of the cling film, it is impossible to effectively ensure that the cling film on the winding roller maintains the same tension during the rolling process, which easily causes the cling film on the winding roller to become loose.

[0003] At present, when adjusting the tension of the cling film, the conventional tension adjusting device presses and tightens the cling film by placing a pressure roller or a pressure wheel on the transmission route of the cling film. In this way, the cling film is easily broken when the transmission speed is different, and the quality of the cling film cannot be effectively guaranteed.

[0004] After searching, Chinese patent publication number CN202322011620.2 discloses a polyimide film winding tension adjustment structure; including a winding mechanism and a tension adjustment mechanism, the winding mechanism includes a base, a guide assembly fixedly connected to the top of one side of the base, and a winding assembly fixedly connected to the top of the other side of the base, the tension adjustment mechanism is located between the guide assembly and the winding assembly, and the tension adjustment mechanism includes a gantry fixedly connected to the base, a hydraulic cylinder fixedly connected to the top of the gantry, a lifting plate fixedly connected to the piston end of the hydraulic cylinder, a mounting frame fixedly connected to the bottom of the lifting plate, a tensioning roller rotatably connected to the inside of the mounting frame, a pointer fixedly connected to the top of the mounting frame, and a standard scale engraved on the inner wall of the gantry;

[0005] The structure in the above patent makes the polyimide film pass through the middle of the tensioning roller and the mounting frame when adjusting the tension. In this way, when the polyimide film is tensioned, the tensioning roller can only move upwards driven by the hydraulic cylinder. When the polyimide film is in a tensioned state for a long time, it needs to be properly relaxed to prevent the polyimide film from being damaged during the winding process. However, when the tensioning roller in the above patent moves downward, the polyimide film will contact the mounting frame, so friction occurs between the mounting frame and the polyimide film, and the quality of the polyimide film cannot be effectively guaranteed.

[0006] In view of the above situation, we provide a tension adjustment device for processing and winding plastic wrap. In this device, a turntable is arranged on one side inside the C-shaped frame, and a connecting plate is eccentrically arranged on the turntable. The connecting plate is connected to the first swing arm and the second swing arm through a connecting rod. When the turntable drives the connecting plate to move, the first swing arm and the second swing arm swing up and down through the rotating shaft. During the swinging of the first swing arm and the second swing arm, the first clamping rod and the second clamping rod on the end fixed frame effectively contact the plastic wrap. In this way, during the process of rolling up the plastic wrap, the tension is adjusted by swinging the first clamping rod and the second clamping rod up and down. In this way, during the adjustment process, the alternating work between tensioning and relaxing the plastic wrap is effectively realized during the transmission of the plastic wrap, and the efficiency of rolling up the plastic wrap is effectively realized.
