Description

Technical Field

[0001] The utility model relates to the technical field of plastic films, and specifically relates to a multifunctional plastic film winding device. Background Technique

[0002] At the end of the production, the plastic film needs to be wound around a paper tube for final sorting and storage, which is convenient for subsequent transportation and sales.

[0003] The publicly disclosed patent No. CN215557581U discloses a plastic film winding device, which includes a support frame. One side of the support frame is fixedly connected with a first motor, and the side of the first motor away from the support frame is fixedly connected with a first tightening column. The inner wall of the support frame is fixedly connected with a second motor, and the side of the second motor away from the support frame is fixedly connected with a lead screw. A slideway is opened inside the support frame, and a moving plate is threadedly connected to the outer surface of the lead screw. Through the cooperative setting among the first motor, the first tightening column, the second motor, the lead screw, the slideway, the moving plate and the second tightening column, it is convenient to replace the paper winding tube and improve the work efficiency. Through the anti-slip sleeve fixedly connected to the outer surface of the second tightening column and the cooperative setting between the locking rod and the spring, with the anti-slip sleeve between the paper winding tube and the second tightening column and the locking rod pressing against the paper winding tube, the fixing effect of the paper winding tube can be increased. However, the following problems still exist in the actual use of this patent:

[0004] After the paper winding tube in the above device is installed, the locking rod presses against the paper winding tube, but the support of the locking rod is provided by a spring. However, with the vibration of the machine, the spring will undergo small-scale expansion and contraction, resulting in the shaking of the locking rod, and further causing small-scale shaking of the paper winding tube. When the paper winding tube rotates, the small-scale shaking of the paper winding tube will cause unnecessary wrinkles in the plastic film, which is not conducive to the stable winding of the plastic film.

[0005] A multifunctional plastic film winding device is proposed to solve the problems raised above. Content of the Utility Model

[0006] The purpose of the utility model is to provide a multifunctional plastic film winding device to solve the problem that after the paper winding tube in the above device is installed, the locking rod presses against the paper winding tube, but the support of the locking rod is provided by a spring. However, with the vibration of the machine, the spring will undergo small-scale expansion and contraction, resulting in the shaking of the locking rod, and further causing small-scale shaking of the paper winding tube. When the paper winding tube rotates, the small-scale shaking of the paper winding tube will cause unnecessary wrinkles in the plastic film, which is not conducive to the stable winding of the plastic film.

[0019] 2. When the plastic film is rolled up, the lever is pushed to slide in the outer ring groove, thereby pulling the step arc plate to slide in the semicircular step groove, so that the step arc plate slides from the semicircular step groove spanning the two semicircular shells to the single semicircular step groove, so that the two rotating partitions can be separated at this time, thereby facilitating the rapid removal of the central paper tube wrapped with the plastic film from the end of the winding shaft.
