Description

Technical Field

[0001] This utility model relates to a winding device for producing lightbox film, belonging to the technical field of winding devices. Background Technology

[0002] Lightbox film is a special thin film material used to create lightbox advertisements. It typically features high transparency, high brightness, and good durability, producing a clear and vibrant visual effect under illumination. Lightbox film is widely used in commercial displays, billboards, shop signs, and other fields, effectively attracting pedestrian attention. After production, lightbox film needs to be rolled into rolls for easy collection and transportation.

[0003] However, in existing technologies, the winding device is independent of the lightbox film production equipment. If the lightbox film production equipment fails to stop in time when the winding device motor stops, the lightbox film rolls collected on the winding rollers in the winding device will become loose and need to be rewound. Therefore, this utility model proposes a winding device for lightbox film production to solve the above problems. Utility Model Content

[0004] Based on the above background, the purpose of this utility model is to provide a winding device for lightbox film production, thereby solving the problems in the background technology.

[0005] This utility model provides the following technical solution:

[0006] A winding device for producing lightbox film includes a base. A first support plate is located on the top left side of the base, and a second support plate is located on the top right side of the base. The first and second support plates are symmetrically arranged. A set of first hinge seats is provided between the first and second support plates at the front end of the base. Each of the first hinge seats has a connecting rod hinged to it. An abutment plate is provided at the end of each connecting rod away from the first hinge seat, and both ends of the abutment plate are fixedly connected to the connecting rod. A second hinge seat is located at the center of the rear end of the base, and a movable plate is hinged to the second hinge seat. A sliding opening is provided on the movable plate. The movable plate has a telescopic hole on its end face away from the second hinge seat. The telescopic hole connects to the sliding port. A telescopic rod is telescopically installed inside the telescopic hole. A sliding block is provided at one end of the telescopic rod inside the sliding port. The sliding block and the sliding port are slidably engaged. A hinge block is fixedly connected to the end of the telescopic rod away from the movable plate. A third hinge seat is hinged to the hinge block. The third hinge seat is fixedly connected to the bottom of the abutment plate. A spring is sleeved on the telescopic rod. One end of the spring abuts against the third hinge seat, and the other end of the spring abuts against the end face of the movable plate away from the second hinge seat.

[0007] Preferably, a first bearing seat is installed on the end face of the first support plate near the second support plate, and a first rotating shaft is rotatably connected to the first bearing seat through a bearing. A first flange head is provided at the end of the first rotating shaft away from the first support plate.

[0008] Preferably, a second bearing seat is installed on the end face of the second support plate away from the first support plate. A second rotating shaft is rotatably connected to the second bearing seat through a bearing. A driven pulley is provided at the end of the second rotating shaft away from the second support plate. The end of the second rotating shaft near the first support plate passes through the second support plate. A second flange head is provided at the end of the second rotating shaft near the first support plate. A take-up roller is flange-connected between the second flange head and the first flange head. The take-up roller is tangent to the top surface of the abutment plate.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] This utility model discloses a winding device for producing lightbox film. An abutment plate is fixedly connected between connecting rods hinged on a set of first hinge seats. A telescopic rod is telescopically mounted on a movable plate hinged on a second hinge seat, and the telescopic rod is connected to the bottom of the abutment plate via a third hinge seat. Under the action of a spring, when the winding roller flange is connected to the first and second flange heads, the top surface of the abutment plate is tangent to the outer cylindrical surface of the winding roller. During the winding of the lightbox film roll, the abutment plate abuts against the lightbox film roll on the winding roller, resulting in a tighter winding.
