Description

Technical Field

[0001] This utility model relates to the field of rewinding device technology, specifically a film printing rewinding device. Background Technology

[0002] Film printing rewinding refers to the process of rewinding the printed film after printing. Rewinding involves rolling a wider substrate into smaller rolls or master rolls to meet different processing requirements. During rewinding, the film is rolled into smaller rolls or master rolls for easier storage and subsequent processing. Film printing rewinding can meet the needs of various industries for film materials, providing high-quality printing effects and stable processing performance.

[0003] Existing film printing rewinding devices suffer from difficulty in controlling film tension during rewinding and transport. When the tension is low, the film becomes loose and cannot be straightened, resulting in a loose finished film roll that fails to meet quality requirements. Furthermore, they often lack dust removal capabilities, affecting film cleanliness and leading to poor product quality and inconvenience. Therefore, we propose a film printing rewinding device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a film printing rewinding device, which solves the problem that film printing rewinding devices are inconvenient to control film tension during rewinding and transmission. When the tension is low, the film is loose and cannot be straightened, resulting in a loose finished film roll that fails to meet quality requirements. Furthermore, it often lacks dust removal function, which affects the cleanliness of the film and leads to poor product quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A film printing rewinding device includes a base plate, a fixed frame fixedly connected to the top of the base plate, an adjusting frame below the fixed frame, a sliding plate slidably connected inside the adjusting frame, springs equidistantly arranged between the sliding plate and the adjusting frame, connecting rods equidistantly fixedly connected to the bottom of the sliding plate, a connecting frame fixedly connected to the end of the connecting rod away from the sliding plate, a tension roller rotatably connected inside the connecting frame, a fixed plate fixedly connected to the top of the base plate, a take-up roller rotatably connected to one side of the fixed plate, a fixed box fixedly connected to the outside of the fixed plate, a sliding rod slidably connected equidistantly inside the fixed box, and a component inside the fixed box that matches the sliding rod. The transmission mechanism is designed for use in conjunction with a dust collection frame. One end of the slide rod is fixedly connected to a dust collection frame, which has dust collection ports evenly spaced on its outer side. A connecting tube is located at the top of the dust collection frame. The tension roller is moved by the adjusting frame, causing it to slightly press the film. With the help of a spring, the film is kept taut during rewinding. The film is rewound by the rotation of the take-up roller. The connecting tube is connected to an external dust collection device, allowing the film to be vacuumed through the dust collection ports on the outer side of the dust collection frame. The transmission mechanism facilitates the movement of the slide rod, which in turn moves the dust collection frame, enabling uniform cleaning of the film.

[0007] Preferably, a fixed frame is fixedly connected to the top of the fixed frame, an adjusting plate is slidably connected inside the fixed frame, and adjusting rods are symmetrically fixedly connected to the bottom of the adjusting plate. The adjusting rods are slidably connected to the fixed frame, and the adjusting frame is fixedly connected to the adjusting rods. The movement of the adjusting plate causes the adjusting rods to move, and the adjusting rods cause the adjusting frame to move.

[0008] Preferably, a lead screw is rotatably connected inside the fixed frame, the adjusting plate is threadedly connected to the lead screw, and a knob is fixedly connected to one end of the lead screw, so that the adjusting plate moves by rotating the lead screw.

[0009] Preferably, the inner wall of the adjustment frame is symmetrically fixedly connected with limit rods, and the sliding plate is slidably connected to the limit rods. The movement of the sliding plate can be limited by the setting of the limit rods.

[0012] Preferably, the transmission mechanism includes fixed blocks, and fixed blocks are fixedly connected at equal intervals to the inner wall of the fixed box. A transmission shaft is rotatably connected between two fixed blocks. A first bevel gear is fixedly connected to one end of the transmission shaft. A second bevel gear that cooperates with the first bevel gear is fixedly connected to the outer side of the take-up roller. The take-up roller drives the first bevel gear to rotate through the second bevel gear, and the first bevel gear drives the transmission shaft to rotate.

[0013] Preferably, a connecting block is fixedly connected to the end of the drive shaft away from the first bevel gear, a pressure block is fixedly connected to one side of the connecting block, and an adjusting frame is fixedly connected to the end of the slide rod away from the dust collector. The adjusting frame has a connecting groove inside that cooperates with the pressure block.
