Description

Technical Field

[0001] The utility model relates to the field of film production, in particular to a packaging film winding machine with an anti-wrinkle structure. Background Art

[0002] After searching Chinese patents, the publication number is: CN213770648U, which discloses a packaging film winding machine, including a frame, a first bearing is bolted inside the frame, a rotating rod is sleeved inside the first bearing, and one end of the rotating rod is sleeved on a first pulley; the utility model drives the threaded shaft to rotate through the cooperation of the threaded sleeve by turning the crank handle, and then the threaded shaft drives the plug to limit and fix the winding roller, and then starts the motor to drive the second pulley to rotate, so that the second pulley drives the first pulley to rotate through the cooperation of the belt, and then the first pulley drives the rotating rod to rotate through the cooperation of the first bearing, so that the rotating rod drives the winding roller to wind the film through the cooperation of the second bearing and the plug, so that it can be effectively applied to winding rollers of different lengths, solving the problem that the existing winding machine has a simple structure and cannot be effectively applied to winding rollers of different lengths.

[0003] The existing film winding machines do not have an anti-wrinkle function. Generally, when a film winding machine is winding the film, the film is wound and rolled up by a guide roller. However, the guide roller rotates along with the film rolling, and it is difficult to adjust the resistance during the rotation, resulting in less tension on the film during the film rolling process, which causes wrinkles, thereby affecting the quality of the winding and rolling. It is inconvenient to use and it is also inconvenient to replace the winding drum. Generally, the winding drum of a film winding machine needs to be replaced after winding is completed, and the winding drum is generally fixed and installed by bolts. When replacing, tools are needed to disassemble and assemble it. The disassembly and assembly process is relatively cumbersome, which increases the workload and reduces the efficiency of replacement. In order to solve the above-mentioned problems, we propose a packaging film winding machine with an anti-wrinkle structure. Utility Model Content

[0015] The utility model is further configured as follows: scale lines are printed on the surface of the winding drum.

[0016] By adopting the above technical solution, the size can be easily adjusted by setting scale lines.

[0017] The utility model is further configured as follows: the surface of the sliding cylinder is provided with anti-slip grooves.

[0018] By adopting the above technical solution, anti-skid patterns are provided to prevent hands from slipping and facilitate operation.

[0019] In summary, the present invention has the following beneficial effects:

[0020] 1. The utility model rotates the first screw to move the lifting plate longitudinally. The longitudinal movement of the lifting plate changes the elastic force of the first spring.
