The side pressure mechanism 2 further includes the side pressure sensing mechanism 23, which can sense the pressure of the side pressure roller 25 during packaging and provide a buffer space for the side pressure roller 25, so as to automatically stop or automatically correct in case of unexpected situations.

[0019] Preferably, the vertical sliding seat 36 is provided with a vertical sliding groove 361, the vertical sliding groove 361 is provided with a vertical sliding block 362, the vertical sliding block 362 is connected with the vertical sliding block 362 through a second spring 363, and the vertical sliding block 362 is connected with the sensing arm 364 and the top pressure roller 31; the end outside of the sensing arm 364 is provided with a second proximity switch 365.

[0020] It should be noted that the vertical sliding seat 36 is also provided with a structure similar to the side pressure sensing mechanism 23, which is connected to the top pressure roller 31 through a vertical slider 362 capable of sliding up and down. The second proximity switch 365 is arranged at a predetermined position. When the top pressure roller 31 contacts the aluminum material, the vertical slider 362 is driven to move upward, the second spring 363 exerts a pulling force on the vertical slider 362, and the film pressure of the top pressure roller 31 on the aluminum material is formed.

[0021] Preferably, the vertical sliding seat 36 is further provided with an adjusting bolt 366, the bottom of the adjusting bolt 366 is connected with the vertical slider 362. The adjusting bolt 366 extends from the top of the vertical sliding seat 36. By rotating the adjusting bolt 366, the maximum upward stroke of the vertical slider 362 can be adjusted.

[0023] The working principle of the automatic pressing mechanism of the aluminum material film sticking machine is as follows: before packaging, the worker inputs the distance data of the side pressure roller 25 and the top pressure roller 31 according to the size of the aluminum material or directly controls the side pressure motor 21 and the top pressure motor 32 to work through the switch, and adjusts the distance of the side pressure roller 25 and the height of the top pressure roller 31 to the corresponding value.

[0024] During the packaging process, if the actual width size of the aluminum material is too different from the distance of the side pressure roller 25, the aluminum material will push the side pressure sliding seat 24 to approach the first proximity switch 29 when passing through the side pressure roller 25. When the distance between them is too close, the first proximity switch 29 is triggered, and the side pressure motor 21 automatically works to adjust the distance of the side pressure roller 25 again. If the actual height of the aluminum material exceeds the maximum lifting height of the top pressure roller 31, the aluminum material will push the top pressure roller 31 to rise when passing through the top pressure roller 31, the sensing arm 364 is away from the second proximity switch 365, and the automatic pressing mechanism of the aluminum material film sticking machine automatically reports an error and stops working.

[0025] As a preferred embodiment, the automatic pressing mechanism can further comprise a control module, which can be a PLC. The control module, as an automatic control module of the aluminum material film sticking machine, can automatically realize the functions of aluminum material transmission and distance adjustment of the pressing roller. Through the control module and the side pressing motor 21 and the top pressing motor 32 with a servo control function, the corresponding lead screw is driven to rotate, thereby automatically controlling the distance of the side pressing roller 25 and the distance of the top pressing roller 31.

[0026] The above is the preferred embodiment of the present application. It should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which are also considered within the scope of protection of the present application.
