[0037] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: first, the multi-layered sheets are stacked and placed on the top of the placement plate 6, and then the movable plate 3 is driven to move downward by the hydraulic telescopic rod 5. The downward movement of the movable plate 3 will drive the hot pressing plate 7, the two first scrapers 8 and the two second scrapers 9 to move downward. Due to the setting of the upper slopes of the first scrapers 8 and the second scrapers 9, when the first scrapers 8 and the second scrapers 9 come into contact with the sheets, each layer of the sheets will be centered (it should be noted that the height of the placement plate 6 is high enough to allow the scrapers to center the multi-layered sheets before the hot pressing plate 7 comes into contact with the top sheet for hot pressing, and during hot pressing, the scrapers continue to move downward without coming into contact with the top of the base 1). Then the hot pressing plate 7 comes into contact with the sheets to hot press the sheets to form a polymer sheet. After hot pressing, glue will overflow around the polymer sheet.

[0038] When the glue needs to be cleaned, it is only necessary to drive the circular groove disk 13 to rotate by the driving motor 14.

When the internal gear 18 is engaged with the missing gear 16, the internal gear 18 will rotate clockwise. When the internal gear 18 is in contact with the arc rack 17, the internal gear 18 will rotate counterclockwise. Each time the internal gear 18 is engaged with the missing gear 16 or the arc rack 17, it will only rotate ninety degrees. The rotation of the internal gear 18 will drive the first rotating plate 20 to rotate. The rotation of the first rotating plate 20 will drive the two first sliders 22 and the second pulley connected thereto to rotate. The movement of the first slider 22 will drive the movable block 27 to move, and the movement of the movable block 27 will It drives the first scraper 8 to move, and the rotation of one of the second pulleys will drive the second belt 29 and the other second pulley to rotate. The rotation of the other second pulley will drive the first pulley connected to it to rotate. The rotation of one of the first pulleys will drive the first belt 28 and the other first pulley to rotate. The rotation of the first pulley will drive the second rotating plate 23 to rotate one hundred and eighty degrees. The rotation of the second rotating plate 23 will drive the second slider 26 to move. The movement of the second slider 26 will drive the fixed rod 24 to move. The movement of the fixed rod 24 will drive the second scraper 9 to move, so that the two first scrapers 8 and the two second scrapers 9 can scrape glue around the hot-pressed polymer sheet, thereby ensuring the effect of hot pressing on the polymer sheet.

[0039] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
