[0034] The working principle is as follows:

[0035] When carrying out the film laminating activity of products such as glass plates, the glass plate can be placed on the upper end of the conveyor belt 3. With the drive of the motor 4 installed at the front end on the right side of the conveyor belt 3, the conveyor belt 3 can realize the rightward transmission of the glass plate. Before the glass plate is transmitted, the PET film installed outside the film roller 7 can be pulled to the lower ends of the film laminating roller 8 and the transmission roller 9. When the glass plate is transmitted to the lower end of the film laminating roller 8 with the conveyor belt 3, the film laminating roller 8 can press the PET film onto the outside of the glass plate. When the glass plate moves to the lower end of the transmission roller 9, the transmission roller 9 can assist in pressing the PET film and the glass plate tightly, so that the PET film is closely attached to the outside of the glass plate. At the same time, the transmission roller 9 can assist in transmitting the glass plate, so that the glass plate is transmitted to the lower end of the cutting assembly 10. After being transmitted to the appropriate position, with the drive of the pulley group 102 installed on the right side of the mounting plate 101, the movement of the cutter 103 can be realized, so that the cutter 103 can cut the PET film. In this way, after the film laminating activity of the glass plate is completed, the discharging activity can be realized from the right side of the conveyor belt 3;

[0036] In order to ensure that when carrying out the film laminating activity of the glass plate, dust is not likely to fly outside and affect the subsequent film laminating quality, for this reason, a dust removal device 11 is arranged at the upper left end of the frame 1. First of all, the connecting frame 112 installed between the two support plates 111 is in an inclined state, so that the first cleaning roller 113 docked on the left side of the connecting frame 112 is in contact with the upper end of the glass plate to be film laminated. In this way, when the glass plate is transmitted, the first cleaning roller 113 can realize the rolling cleaning activity on the upper end of the glass plate. In this way, the cleaning of the dust flying on the upper end of the glass plate can be conveniently realized, and the subsequent film laminating quality of the glass plate can be guaranteed;

[0037] When the cleaning effect of the first cleaning roller 113 decreases, the servo motor 1153 installed inside the driving swing assembly 115 can be driven, so that the servo motor 1153 rotates the driving disc 1154 connected to the top, so that it swings to the left. In this way, the first column 1155 docked at the lower front side of the driving disc 1154 can assist in realizing the leftward movement of the docking rod 1156. With the leftward movement of the docking rod 1156, the second column 1158 docked with the upper end of the docking rod 1156 can drive the left swing of the swing plate 1157 accordingly. Thus, the rotating shaft 1159 docked at the middle of the upper end of the swing plate 1157 and the connecting frame 112 between the two support plates 111 can be driven by the rotation of the rotating shaft 1159 to realize the swing adjustment activity, so that the second cleaning roller 114 on the right side of the connecting frame 112 can be adjusted to the lower end to carry out the rolling cleaning of the upper end of the glass plate, while the first cleaning roller 113 on the left side of the connecting frame 112 can be lifted away from the glass plate. In this way, the continuity of the rolling cleaning process of the glass plate can be guaranteed without stopping the machine, resulting in the interruption of the cleaning process;

[0038] Secondly, when the first cleaning roller 113 or the second cleaning roller 114 needs to be disassembled and replaced, the gear 11642 connected to the pressing member 1164 can be rotated to enable the gear 11642 to realize the transmission of the first rack 11643 and the second rack 11644 meshing at the upper and lower ends. In this way, the first rack 11643 and the second rack 11644 can move relatively to synchronously realize the pulling of the outer side connected moving plate 11645. In this way, the lock shafts 11649 set at the two outer ends of the moving plates 11645 on both sides will move into the pressing member. The pressing block 11641 is inserted into the interior of the connecting groove 1161 to release the plug-in lock of the lock holes 1163 provided at the four corners of the connecting groove 1161. In this way, the pressing block 11641 can be taken out from the interior of the connecting groove 1161 as a whole to realize the unlocking activity on one side of the first cleaning roller 113 or the second cleaning roller 114, and the other side can be operated in the same way. In this way, the first cleaning roller 113 or the second cleaning roller 114 can be unlocked conveniently for convenient replacement. When the first cleaning roller 113 or the second cleaning roller 114 is re-connected to the left or right side of the connecting frame 112, , it is necessary to rotate the connecting frame 112 again, so that the movable plates 11645 on both sides cooperate with the connection effect of the connecting pipe 11646 and the guide rod frame 11647 on the inner side to perform a stable inward movement. When the movable plates 11645 on both sides move inward, the compression springs 11648 on both sides of the guide rod frame 11647 are squeezed, so that the compression springs 11648 are in a squeezed and force-storing external top state. At this time, after the connecting ends of the first cleaning roller 113 and the second cleaning roller 114 move into the connecting groove 1161, the pressing piece 1164 can be placed into the connecting groove 1161. The inside of the connecting groove 1161 is connected, and the gear 11642 is loosened to allow the compression springs 11648 squeezed on both sides of the guide rod frame 11647 to rebound, and the movable plates 11645 on both sides are pushed outward, thereby automatically realizing the reinsertion and locking of the locking holes 1163 provided at the two outer ends of the movable plates 11645 on both sides and the locking holes 1163 opened in the connecting groove 1161, so as to conveniently complete the quick installation of the first cleaning roller 113 and the second cleaning roller 114, thereby achieving the advantage of convenient disassembly and assembly of the first cleaning roller 113 and the second cleaning roller 114 as a whole.

Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents.
