[0024] Guide components 10 are provided on both sides of the bracket 1, and the guide components 10 are respectively connected to the heating box connecting plate 420 and the vacuum chamber connecting plate 520.
[0025] The guiding assembly 10 includes a guiding shaft 1010, a heating chamber bushing 1020, and a vacuum chamber bushing 1030.

The heating chamber bushing 1020 is connected to the heating chamber connecting plate 420, and the vacuum chamber bushing 1030 is connected to the vacuum chamber connecting plate 520.
[0026] The working principle of the present invention: Initial state: When the device is in the standby state, the heating chamber 7 and the vacuum chamber 8 are respectively installed on the heating chamber driving assembly 4 and the vacuum chamber driving assembly 5 on the optical axis 2.
[0027] The optical axis 2 is fixedly installed on the bracket 1 through the bearing block 3. The optical axis driving assembly 6 is in an inactive state, that is, the driving motor 610 is not started, and the chain between the driving sprocket 620 and the driven sprocket 630 is in a slack state.
[0028] The heat insulation plates 9 on both sides of the heating chamber 7 play a role in heat preservation and preventing heat dissipation.
[0029] Start and transmission: When film laminating is required, the driving motor 610 is started. The driving motor 610 outputs power to drive the driving sprocket 620 to rotate. Through chain transmission, the driven sprocket 630 and the optical axis 2 fixed thereto start to rotate.
[0030] The rotation of the optical axis 2 drives the heating chamber driving assembly 4 and the vacuum chamber driving assembly 5 installed thereon to rotate together.
[0031] Movement of the heating chamber and the vacuum chamber: As the heating chamber cam 410 in the heating chamber driving assembly 4 rotates with the optical axis 2, the first track 430 in the shape of a shoe guides the bearing at the lower end of the heating chamber connecting plate 420 to slide. This design enables the heating chamber 7 to perform a reciprocating motion in the vertical plane to realize heating and film laminating on the surface of the paper food packaging box.
[0032] The vacuum chamber cam 510 and its second track 530 in the shape of a shoe in the vacuum chamber driving assembly 5 guide the bearing at the lower end of the vacuum chamber connecting plate 520 to slide, enabling the vacuum chamber 8 to perform a reciprocating motion in the vertical plane to realize vacuum adsorption and film laminating on the surface of the paper food packaging box.
[0033] Guiding and stability: The guiding assemblies 10 on both sides of the bracket 1 respectively provide additional support and guidance for the heating chamber connecting plate 420 and the vacuum chamber connecting plate 520 through the guiding shaft 1010, the heating chamber bushing 1020, and the vacuum chamber bushing 1030, ensuring their stability and accuracy during the movement process.
[0034] Film laminating process: Under the combined action of the heating box 7 and the vacuum chamber 8, the paper food packaging box is first heated by the heating box 7 to soften the film laminating material and make it adhere to the surface of the food packaging box; subsequently, the vacuum chamber 8 further tightly adsorbs the film laminating material on the surface of the food packaging box through vacuum adsorption, forming a firm film laminating layer.
[0035] Circulation and reset: With the continuous rotation of the optical axis 2, after the heating box 7 and the vacuum chamber 8 respectively complete their heating and adsorption actions, they will return to the initial position to prepare for the film lamination of the next paper food packaging box.
[0036] By controlling the rotation speed and direction of the driving motor 610, precise control of the film laminating speed and the number of film laminating times can be achieved.
[0037] The above embodiments are only illustrative of the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
