[0026] As the LED strip is unreeled, the guiding wheel will be driven to rotate, and the first pulley 604 connected to it will also rotate synchronously. The first pulley 604 drives the second pulley 605 to rotate through the belt 606. The second pulley 605 drives the gear 603 connected to it to rotate. This gear 603 drives another gear 603 to rotate through meshing. The cleaning roller 602 connected to the other gear 603 will also rotate synchronously. The cleaning roller 602 will continue to push the impurities in front of the LED strip forward during movement, making the subsequent bonding of the LED strip more firm.

[0027] As Figure 2 and Figure 4 shown, a pressing component 7 is installed outside the support frame 2, and the pressing component 7 is on the other side of the support frame 2.

[0028] The pressing component 7 includes an extension frame 701 fixedly connected to the outer wall of the other side of the support frame 2.
