[0044] An upper rubber coating roller 314 is installed on one side of the auxiliary film pressing frame 312 in the upper bracket 318 through a cylinder, and a circular cutting roller 315 is symmetrically installed in the middle of the film hanging frame 302. Circular cutting knives 316 are sleeved on both ends of the circular cutting roller 315. A discharge roller 4 is installed on one end of the replacement frame 301 away from the loading roller 1.

[0045] Auxiliary components 5 are installed on the top surfaces of the upper roller 1, the middle roller 2 and the lower roller 4. The auxiliary components 5 include a thickness measuring instrument 501, a front pressure roller 502, a rear pressure roller 503, a cleaning box 504, a cleaning roller 505 and a limit roller group 506;

[0046] A thickness measuring instrument 501 is installed on one side of the top surface of the feeding roller 1, a front pressure roller 502 is installed on the top surface of the middle roller 2 at one side of the replacement frame 301 through a cylinder, and a rear pressure roller 503 is installed on the top surface of the middle roller 2 at the other side of the replacement frame 301 through a cylinder. The front pressure roller 502 and the rear pressure roller 503 are at the same horizontal height, and the front pressure roller 502 and the rear pressure roller 503 are the same size, which is convenient for stable glass transportation. A cleaning box 504 is installed in the middle of the top surface of the unloading roller 4, and a cleaning roller 505 is symmetrically installed between the two cleaning boxes 504. A limited roller group 506 is installed inside the feeding roller 1. The output end of the degree measuring instrument 501 is electrically connected to the input end of the external controller, and the unwinding motor 306, the hot fuse 311, the cylinder of the movable pressure roller 307, the cylinder of the lower rubber-coated roller 308, the cylinder of the movable suction cup frame 309, the cylinder of the hot fuse frame 310, the cylinder of the auxiliary film pressing frame 312, the cylinder of the high-pressure air nozzle 313, the cylinder of the upper rubber-coated roller 314, the cylinder of the circular cutting roller 315, the cylinder of the front pressure roller 502, and the cylinder of the rear pressure roller 503 are electrically connected to the output end of the external controller respectively, and the input end of the external controller is electrically connected to the output end of the external power supply to ensure that all electrical equipment can work normally.

[0047] The working principle and use process of the present invention are as follows: the glass is put on the top surface of the loading roller 1, and the thickness measuring instrument 501 completes the online detection of the glass thickness, so as to facilitate the subsequent adjustment and fixing of the glass. The unwinding motor 306 unwinds the upper film roll 303 and the lower film roll 304, and the film unwound by the upper film roll 303 is below the movable pressure roller 307, and the film unwound by the lower film roll 304 is above the lower rubber-coated roller 308;

[0048] When the glass approaches the front pressure roller 502, the front pressure roller 502 is driven by the cylinder to accurately descend, press the glass, and continue to transport the glass to the film hanging rack 302. The upper bracket 318 descends to drive the movable pressure roller 307 to be close to the upper surface of the glass, and the lower rubber roller 308 rises to be close to the lower surface of the glass under the action of the cylinder. At this time, the ends of the unrolled films of the upper film roll 303 and the lower film roll 304 are attached to the two sides of the glass, and the upper and lower movable suction cup racks 309 are respectively close to the top and bottom surfaces of the glass under the action of the cylinder to achieve film hanging;

[0049] The movable suction cup frame 309 is powered off and quickly separated from the glass surface under the action of the cylinder. The auxiliary film pressing frame 312 quickly approaches the upper surface of the glass under the action of the cylinder, and the front end of the film about 20 mm is hung on the glass. The high-pressure air nozzle 313 releases the air pressure to squeeze the end of the film about 20 mm long on the lower surface of the glass onto the glass surface, so that the ends of the film are attached to the two sides of the glass.

[0050] When the upper rubber coating roller 314 contacts the glass, the auxiliary film pressing frame 312 quickly separates from the glass and returns to its original position. At the same time, the high-pressure air nozzle 313 stops releasing air, and the front pressing roller 502 rises and returns to its original position.

[0051] When the glass reaches below the circular cutter 316, the upper and lower circular cutters 316 drive the circular cutter roller 315 sleeved with the circular cutter 316 under the drive of the cylinder, and the circular cutter 316 quickly sticks to the glass surface. When the glass moves forward, the circular cutter 316 cuts off the excess film on the glass;

[0052] When the glass reaches the bottom of the rear pressure roller 503 at the outlet end, the front pressure roller 502 and the rear pressure roller 503 stick to the glass under the action of the cylinder, clamp the glass and continue to move forward. When the end of the glass approaches the movable pressure roller 307, the movable pressure roller 307 and the lower rubber-coated roller 308 quickly leave the glass surface under the action of the cylinder.

[0053] When the glass is about to be coated, the upper and lower movable suction cup frames 309 are driven by the cylinder to quickly approach the glass and suck the film. After the film is completely attached, the upper and lower movable suction cup frames 309 are driven by the cylinder to quickly leave the glass surface, so that the film and the glass surface form an angle. At this time, the power supply of the hot fuse 311 can be started, and the hot fuse frame 310 is driven by the cylinder to approach the inclined film to cut the film. At the same time, the upper and lower movable suction cup frames 309 suck the film and quickly return to their original positions driven by the cylinder.

[0054] Next, the hot fuse 311 quickly leaves the film and returns to its original position under the action of the cylinder. The glass continues to be squeezed by the upper rubber roller 314 and the top surface of the middle roller 2 under continuous transportation, so that the film continues to adhere to the outer side of the glass. After the end coating is completed, the upper rubber roller 314 retreats to its original position under the action of the cylinder.

[0055] After the film cutting of a piece of glass is completed, the circular cutter 316 quickly leaves the glass surface and returns to the origin under the action of the cylinder. After the end of the glass is coated, the rear pressure roller 503 rises and returns to the original position under the action of the cylinder, completing the coating process, and is cleaned by the cleaning roller 505 to remove the trimming residue and other debris adhering to the outside of the coating, completing the coating operation;

[0056] When the upper film roll 303 and the lower film roll 304 of the film hanging rack 302 are used up and need to be replaced, only the film hanging rack 302 needs to be pulled out from the replacement rack 301, and one person can complete the film replacement. The replacement is simple and the work efficiency is effectively improved. There are a large number of film hanging racks 302, and the upper film roll 303 and the lower film roll 304 of each film hanging rack 302 are of different sizes. Multiple hollow glass panels of different sizes can be coated at the same time, with a wider coating range and high coating efficiency.

[0057] Finally, it should be noted that the above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
