The push rod 54 is also detachably connected to the connecting frame 55 by bolts; the rotary motor 561 is also detachably connected to the film pressing frame 52, which facilitates the replacement of a film pressing frame 52 of a suitable size according to the size of the suitcase body 4, making the device more widely applicable.

[0030] In one specific embodiment of this utility model, the displacement component 3 includes a mounting shaft 31 rotatably mounted on the vertical frame 1 at both ends. Two limiting wheels 32 are slidably mounted on the mounting shaft 31. The two limiting wheels 32 are located on both sides of the movable bracket 8, and both limiting wheels 32 are fixed to the mounting shaft 31 by bolts. One end of the mounting shaft 31 passes through the vertical frame 1 and is equipped with a drive sprocket 33. The drive sprockets 33 of adjacent displacement components 3 are connected by a chain. The mounting shaft 31 of one displacement component 3 is fixedly connected to the output shaft of the drive motor 9.

[0031] In this embodiment, the movable bracket 8 is provided with a mounting groove 81 for limiting the position of the suitcase body 4. The top of the movable bracket 8 is also provided with a cutting groove 82, which surrounds the mounting groove 81 and is adapted to the cutting groove 522. A heater 57 is also fixed to the top of the film pressing frame 52. A heat-conducting layer 524 is fixedly installed in the film pressing groove 521 of the film pressing frame 52. The heat-conducting layer 524 is connected to the heater 57 and is used to heat the film to ensure it adheres tightly to the suitcase body 4. Anything that can achieve the aforementioned performance functions of the film pressing frame 52 and heater 57 is within the scope of protection of this application.

[0032] Compared with existing technologies, this suitcase film application device, through the setting of displacement component 3, can automatically transport the movable bracket 8 carrying the suitcase body 4, ensuring automated transmission of the film application process, reducing manual intervention, and lowering labor costs; through the cooperation of film pressing component 5 and winding roller 6, it can automatically apply film to the suitcase body 4 and cut the film, ensuring work efficiency in the film application process; through the setting of heater 57 in film pressing component 5, it can ensure that the film is tightly adhered to the suitcase body 4, ensuring the film application effect; through the cooperation of film pressing frame 52 and movable bracket 8 in film pressing component 5, it can better limit the position of suitcase body 4, resulting in a better film application effect.

[0033] The working process of this utility model's trolley case film applicator is as follows: The size of the movable bracket 8 is determined based on the dimensions of the trolley case body 4. The positions of the two limiting wheels 32 on the mounting shaft 31 are adjusted so that the two limiting wheels 32 are precisely positioned on both sides of the movable bracket 8. Simultaneously, the film pressing frame 52 in the film pressing assembly 5 is replaced with a structure matching the dimensions of the movable bracket 8. The trolley case body 4 is placed in the mounting groove 81 of the movable bracket 8. The movable bracket 8 is then conveyed to the displacement assembly 3 via a conveyor belt. The drive motor 9 drives the mounting shaft 31 to rotate, and the drive sprocket 33 on the mounting shaft 31 drives the adjacent displacement assembly 3 to move via a chain. All displacement assemblies 3 rotate synchronously. The displacement component 3 moves the movable bracket 8 to a position opposite to the film pressing frame 52 and then stops. During the movement of the movable bracket 8, the winding motor 7 starts and drives the winding roller 6 to rotate, winding up the film waste cut off after the previous film application and pulling out the film material. After the winding motor 7 stops working, the movable bracket 8 moves into position, and the pull-along box body 4 is located below the film material. At this time, the telescopic cylinder 51 drives the film pressing frame 52 to move down. The film pressing frame 52 presses the film against the pull-along box body 4 and clamps the film between the film pressing frame 52 and the movable bracket 8. At this time, the rotary motor 561 starts, driving the connecting frame 55 downward through the rotating block 562 and the rotating rod 563. The connecting frame 55 drives the cutter 53 downward through the push rod 54 to cut the film. After the cutting is completed, the rotary motor 561 lifts the cutter 53. After cutting, heater 57 is activated to heat the heat-conducting layer 524. The heat from the heat-conducting layer 524 causes the film to adhere well to the surface of the suitcase body 4, completing the film application process. The film pressing frame 52 moves upward, and the displacement component 3 is activated to transfer the moving bracket 8 and the film-applied suitcase body 4 onto the conveyor belt.

[0034] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section. The above-described embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model.
