Description

Technical Field

[0001] This utility model relates to the field of protective films, and in particular to a hot pressing processing device for household appliance protective films. Background Technology

[0002] As an important protective component for home appliances before they leave the factory, protective films for home appliances effectively prevent scratches, stains, or damage to the surface of appliances during transportation, storage, and sales, ensuring the integrity of the appliance's appearance and its safety during use. Hot pressing is a key process in the production of protective films for home appliances, and its processing quality directly affects the film's adhesion, durability, and protective effect. Therefore, the research and application of specialized hot pressing equipment is of significant practical importance.

[0003] In existing technologies, the hot pressing of protective film for home appliances mostly relies on simple brackets and manual operation. Workers need to first lay the protective film flat on the surface of the home appliance to be processed or on a special mold, manually adjust its position and press it to fix it, and then manually control the downward pressure and time through the heating plate. After the hot pressing is completed, the workpiece is manually removed. The entire operation process depends on manual intervention.

[0004] However, manual fixing makes it difficult to ensure uniform stress on the protective film, and displacement and wrinkling are prone to occur during hot pressing. This results in poor adhesion of the protective film after hot pressing, with air bubbles or edge lifting. This not only affects the appearance quality of home appliances but also reduces the protective performance and lifespan of the protective film, making it difficult to meet the needs of large-scale production. To address these issues, a hot pressing processing device for home appliance protective films is proposed. Utility Model Content

The fixing mechanism 5 includes a placement seat 51, which is fixedly connected to the top of the workbench 1 and is used to place the appliance protective film. A groove is provided on the front of the placement seat 51 for mounting a fixing shaft 52. The fixing shaft 52 is fixedly connected to the inner wall of the groove to limit the movement of the fixing clamp 53. Two fixing clamps 53 are slidably fitted onto the outer wall of the fixing shaft 52, symmetrically arranged on the outer wall of the fixing shaft 52, for pressing and fixing one end of the protective film. A sliding groove 56 is provided on the side of the fixing clamp 53 to facilitate its movement for fixing. The top of the workbench 1 is fixedly mounted with... A first electric actuator 54 is installed to facilitate the back-and-forth movement of the push plate 55. The output end of the first electric actuator 54 is fixedly connected to the push plate 55 to facilitate the movement of the moving rod 57. The moving rod 57 is fixedly connected to the inner wall of the push plate 55, and the moving rod 57 movably passes through the slide groove 56 and is slidably connected to the inner wall of the slide groove 56. The back-and-forth movement of the moving rod 57 drives the fixing clamp 53 to rotate along the fixing shaft 52, thereby fixing one end of the protective film. A second electric actuator 58 is fixedly installed on the top of the inner wall of the placement seat 51 to drive the push block 59 to move back and forth. The output end of the second electric actuator 58 is fixedly connected to the front of the push block 59.

The two slide blocks 511 are respectively set on the inner side of the two fixed clamps 53, which facilitates the synchronous reverse movement of the two fixed clamps 53.

[0026] Reference Figure 4A flattening mechanism 6 is provided on the top of the workbench 1. The flattening mechanism 6 includes a guide rail 61, which is fixedly connected to the top of the workbench 1 to provide a moving path for the linear motor 62. The linear motor 62 is slidably connected to the top of the guide rail 61 to facilitate the forward and backward movement of the mounting frame 63. The mounting frame 63 is fixedly connected to the top of the linear motor 62 to mount a third electric actuator 64. The third electric actuator 64 is fixedly connected to the top of the mounting frame 63 to drive the lifting frame 65 to rise and fall. The output end of the third electric actuator 64 movably passes through the top of the mounting frame 63 and is fixedly connected to the lifting frame 65 to mount a flattening roller 66. The flattening roller 66 is rotatably connected to the inner wall of the lifting frame 65 to flatten the protective film. The protective film is flattened to remove excess air bubbles. The side of the mounting frame 63 has a movable groove 67. A slider 68 is slidably connected to the inner wall of the movable groove 67, and the slider 68 is fixedly connected to the outer wall of the lifting frame 65 to improve the movement stability of the lifting frame 65. A guide rod 69 is fixedly connected to the bottom of the inner wall of the movable groove 67, and the top of the guide rod 69 moves through the bottom of the slider 68 and is fixedly connected to the top of the movable groove 67 to make the lifting of the lifting frame 65 more stable. A spring 610 is sleeved on the outer wall of the guide rod 69. The two ends of the spring 610 are fixedly connected to the bottom of the inner wall of the movable groove 67 and the bottom of the slider 68, respectively. Through the elastic force of the spring 610, the flattening roller 66 can stably flatten the protective film.

[0027] Working principle: The appliance protective film is placed on the placement seat 51. The second electric push rod 58 is activated, driving the push block 59 to move. The push block 59 pulls the slide block 511 along the fixed shaft 52 through the hinge rod 510, so that the two fixing clamps 53 adjust the spacing in opposite directions to fit the size of the protective film. Then, the first electric push rod 54 pushes the push plate 55 to move. The push plate 55 drives the moving rod 57 to slide in the slide groove 56, driving the fixing clamps 53 to rotate along the fixed shaft 52, pressing and fixing the two ends of the protective film. The third electric push rod 64 is activated to push the lifting frame 65. The pressure roller 66 descends, allowing it to adhere to the surface of the protective film. The slider 68 slides along the guide rod 69 within the movable groove 67, with the spring 610 providing a buffering force. The linear motor 62 moves along the guide rail 61, driving the pressure roller 66 to roll, removing air bubbles from the protective film and flattening it. After flattening, the pressure roller 66 separates from the placement seat 51 without affecting the descent of the hot press plate 4. The hydraulic cylinder 3 drives the hot press plate 4 to descend, performing hot pressing on the protective film. The reinforcing ribs 7 on the inner wall of the bracket 2 enhance structural stability. After hot pressing, all components reset, completing the processing.
