Two-time traction moving winding device

Abstract

In order to solve the problem that after a sheet or a film is wound, a sheet roll or a film roll on a winding device needs to be manually unloaded and carried to a designated position of subsequent processing equipment, a movable winding trolley device needs to be designed. Meanwhile, due to the fact that a motor is adopted to directly drive a winding shaft in traditional winding, the winding speed can be changed along with increasing of the diameter of the winding shaft. In order to solve the problem, a complicated control program and a variable frequency motor need to be used, so that the speed of the winding process is uniform by setting a twice traction mode. The utility model provides a twice-traction movable winding trolley device which comprises a rack and a guide carrier roller arranged on the rack, and a driving traction device is arranged on the rack; two parallel winding stations are arranged below the rack; the winding station comprises a base, a driving table and a winding trolley; the driving table is arranged on the top surface of one side of the base; the winding trolley is pushed above the base and is matched with the base; and the winding vehicle is driven by the driving table.

Description

Technical Field

[0001] The utility model relates to the field of plastic film production, specifically to a double-traction mobile winding device Background Art

[0002] After a sheet or film production device completes production of a sheet or film, it is usually necessary to reel the sheet or film and then transfer the reeled sheet or film to other equipment (such as a thermoforming machine) for subsequent processing. However, existing reeling devices are generally fixedly installed on the rear side of the sheet or film production device and cannot be moved according to production needs. After the sheet or film is reeled, it is necessary to manually remove the sheet or film roll from the reeling device and transport it to a designated location on the subsequent processing equipment. This not only increases the labor intensity of workers, resulting in high labor costs, but also reduces work efficiency. In addition, due to the randomness of workers' operations, the surface of the sheet or film roll is easily damaged during the transportation process, thereby reducing the quality of the sheet or film. Summary of the Invention

[0003] To address the problem of manually removing the roll from the winding device and transporting it to a designated location on subsequent processing equipment after winding the sheet or film, a mobile winding trolley device was designed. Furthermore, because traditional winding uses a motor to directly drive the winding shaft, this can cause the winding speed to vary as the shaft diameter increases. To address this issue, a complex control program and variable frequency motor were used. To achieve this, a two-pulling method was implemented to ensure a uniform winding speed.

[0004] The double-traction mobile winding device includes a frame and guide rollers arranged on the frame, an active traction device is arranged on the frame; two parallel winding stations are arranged under the frame;

[0005] The winding station includes: base, drive platform and winding car;

[0006] The driving platform is arranged on the top surface of one side of the base; the winding car is pushed into the top of the base and matched with the base; the winding car is driven by the driving platform.

[0007] For example, in the production of plastic film, traction film is used. Two films are laminated together and drawn into the machine via an active traction mechanism along guide rollers. After passing through the active traction mechanism, the films are separated left and right, or front and back, as they are fed under the machine frame. The finished film and traction film are then distributed to two winding cars. A drive station rotates the winding shafts on the winding cars, providing secondary traction to the film, which is suspended on the machine frame rollers.

[0013] The active traction device is arranged at the midpoint of the long side of the top surface of the frame, and the winding axis of the active traction device is parallel to the short side of the frame.

[0014] The fitting pressure between the rubber roller and the steel rod can be adjusted by adjusting the telescopic cylinder.

[0020] The base on the winding car can determine the working position and reduce shaking, while facilitating the connection of the winding motor.
