The rotation of the output shaft of the first servo motor drives the cutting knife to rotate at high speed to cut the back panel. After the edges are cut and milled, the PUR glue is injected into the automatic hot melt glue machine. The piston rod of the first cylinder drives the dual-channel glue coating head to rise or fall. The piston rod of the second cylinder drives the dual-channel glue coating head to rise or fall. The channel glue coating head moves to the left or right, and the automatic hot melt glue machine melts the PUR glue. The double-channel glue coating head evenly coats the hot melt PUR glue between the two back panels, leaving 0.1-1mm on the upper and lower outer surfaces of the two substrates. After cooling for 10-20 seconds, take out the back panel. Since the PUR glue has strong willfulness, the glue coating layer bonds the two substrates together, so that the two back panels can be unfolded 180 degrees for use. One station of the device can process four products, which ensures the quality and doubles the efficiency, thereby reducing the production of finished products;

[0015] 2. The product that originally required two devices to complete in one day can now be completed in one day with one device, which reduces equipment investment, thereby reducing energy consumption, being more environmentally friendly and more economical;

[0016] 3. Save labor. The work that used to take two people a day can now be completed by one person in a day. BRIEF DESCRIPTION OF THE DRAWINGS
