Description

Technical Field

[0001] This utility model relates to the field of decorative film production equipment, and in particular to a decorative film production equipment with an automatic roll changing function. Background Technology

[0002] Decorative film, a material that combines aesthetics, functionality, and protection, is widely used in construction, furniture, electronics, and automotive industries. In the production process of decorative film, the traditional method of changing rolls typically involves manually transporting new rolls to the installation location and replacing them. This method results in high labor costs, low production efficiency, and difficulty in guaranteeing the accuracy of manual replacement, which can affect the operation of subsequent production lines.

[0003] The manually adjustable tensioning mechanism allows for tension adjustment through manual operation. The operator rotates the threaded cylinder to adjust the height of the base plate, changing the pressure of the tension roller on the decorative film and thus adjusting the film tension. This manual adjustment method breaks the rigidity of fixed tensioning structures, allowing operators to adjust the tension based on the actual condition of the decorative film and the winding effect, relying on experience. Maintaining constant tension during film changing and conveying is crucial. Torsion spring guide wheels can compensate for changes in film tension to some extent. When film tension fluctuates, the torsion spring guide wheels can absorb or release some energy through their elastic deformation, thus buffering and stabilizing the tension. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic roll-changing decorative film production equipment. By adjusting the threaded cylinder to control the tension of the decorative film, it ensures the film remains uniformly taut during winding, preventing loose edges, wrinkles, or layer misalignment. This guarantees a flat surface and neat edges on the decorative film roll, facilitating subsequent storage and transportation. The adjustment function reduces downtime for troubleshooting caused by abnormal tension, preventing film waste. The torsion spring guide wheel, through the elastic force of the torsion spring, maintains close contact with the decorative film to absorb or release energy, buffering and stabilizing tension. This also reduces hard collisions and friction between the guide wheel and the film material, minimizing wear and tear on both, extending their service life, and lowering equipment maintenance and material consumption costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a decorative film production equipment with automatic roll changing function, comprising a base plate, support plates fixedly connected to the left and right sides of the front end of the base plate, a support plate fixedly connected to the front side of the top of the support plate, a first drive shaft rotatably connected to the middle of the support plate, rotating claws fixedly connected to both ends of the first drive shaft, a second drive shaft rotatably connected to the adjacent side of the two support plates, a third drive shaft provided at the upper end of the second drive shaft, a transmission assembly provided at the right end of the second and third drive shafts, an adjustment frame fixedly connected to the top two sides of the base plate, a threaded rod rotatably connected to the middle of the adjustment frame, a threaded cylinder threadedly connected to the outer wall of the threaded rod, a base frame fixedly connected to the adjacent side of the threaded cylinders on the left and right sides, a fixed plate fixedly connected to the top of the base frame, limit boxes fixedly connected to both sides of the fixed plate, a tensioning assembly provided at the top of the limit box, and a guide assembly provided at the rear top of the base plate.

The tension of the decorative film is adjusted significantly. After passing through the tension roller 20, the decorative film is wound up on the third drive shaft 8. When the third drive shaft 8 is wound up to a certain extent, the decorative film will touch the first control button 10. After touching it, the first motor 29 stops rotating and the second motor 30 starts. After starting, it drives the rotating claw 5. The rotating claw 5 will bring the wound third drive shaft 8 to the guide frame 32. After falling onto the guide frame 32, the decorative film will touch the second control button 11. After the second control button 11 is activated, the first motor 29 starts and the second motor 30 stops. After the third drive shaft 8 is placed on the guide frame 32, the winding shaft placed on the ramp set at the rear end of the middle of the support plate 2 will automatically fall onto the second drive shaft 6.
