[0045] In another embodiment of the present invention, Figures 1-2As shown, the supporting mechanism 20 includes a longitudinal driving member (not shown in the figure), a suction plate 22, a clamping cylinder 23, a clamping member 24 and a volute fan (not shown in the figure); the longitudinal driving member is installed on the frame 10, the suction plate 22 is installed on the longitudinal driving member, the volute fan is connected to the suction plate 22, the upper end surface of the suction plate 22 is provided with a plurality of suction holes connected to the volute fan, the clamping cylinder 23 is installed at the bottom of the suction plate 22, and the clamping member 24 is installed on the piston rod of the clamping cylinder 23 and is located on the side of the suction plate 22. Specifically, the glue lowering mechanism 50 clamps the free end of the tape between the clamping member 24 and the suction plate 22, and then the clamping cylinder 23 drives the clamping member 24 to move toward the suction plate 22, thereby clamping the tape.

Each of the floating roller assemblies 84 is located below each of the roller assemblies 83, and the adhesive tape alternately passes through the roller assemblies 83 and the floating roller assemblies 84. Specifically, during the film laminating process, the constant tension cylinder 81 drives the floating seat 82 to move up and down, thereby driving each of the floating roller assemblies 84 to move away from or close to each of the roller assemblies 83, thereby maintaining a constant tension of the portion of the adhesive tape that alternately passes through the roller assemblies 83 and the floating roller assemblies 84.

[0050] In another embodiment of the present invention, Figure 3 As shown, the constant tension mechanism 80 further includes a limit block 85, which is mounted on the transfer mechanism 30 and is located below the constant tension cylinder 81. Specifically, the limit block 85 is used to limit the movement stroke of the floating seat 82 to ensure that the tape that alternately passes through the roller assembly 83 and the floating roller assembly 84 is not over-tensioned.

[0051] In another embodiment of the present invention, a silicone sheet is provided at the upper end of the limit block 85 .

Specifically, the free end of the tape passes through the tape channel. When working, the transfer mechanism 30 drives the vertical drive member 51 to move between the suction plate 22 and the clamping member 24. Then, the glue pressing assembly 54 cooperates with the clamping plate 53 to clamp the tape. Then, the vertical drive member 51 drives the lower tape bottom plate 52 to move downward, thereby pulling the tape to move downward. Then, the vertical drive member 51 is reset, so that the free end of the tape is located between the clamping member 24 and the suction plate 22. The clamping member 24 and the suction plate 22 clamp the free end of the tape. The transfer mechanism 30 drives the vertical drive member 51 to move horizontally. During the movement, the tape is adhered to the surface of the product along the lower tape roller 56. After the adhesion is completed, the pressing and cutting mechanism 70 cuts the tape, and the above steps are repeated to achieve the adhesion of the protective film to the surface of the product; a channel for the tape to pass through is formed between the glue guide plate 55 and the clamping plate 53, which can guide the protective film. The cooperation between the glue pressing component 54, the clamping plate 53 and the vertical driving component can realize the movement of the free end of the tape to between the clamping member 24 and the suction plate 22, thereby ensuring that the free end of the tape is fixed during the film sticking process, thereby improving the stability of the film sticking.

[0055] In another embodiment of the present invention, Figures 3 to 5 As shown, the glue pressing assembly 54 includes a glue pressing cylinder 541, a glue pressing plate 542 and a die-cutting foam 543; the glue pressing cylinder 541 is installed on the side of the clamping plate 53, the glue pressing plate 542 is installed on the piston rod of the glue pressing cylinder 541, and the die-cutting foam 543 is installed on the glue pressing plate 542.

Specifically, according to different widths of the adhesive tape, the fine-tuning component 57 is adjusted to adapt to different widths of the adhesive tape, and a limiting effect is achieved when the adhesive tape moves, so that the protective film will not shake during the movement, thereby improving the stability of the coating.
