In the process of inserting the first rotating roller 501 into the other end of the film winding drum rightward, since the space occupied by the first oil passage 505 in the first hydraulic chamber 502 decreases, the pressure in the first hydraulic chamber 502 may slightly decrease, the arc-shaped plate 5093 may slightly contract, and there may be a slight tightening clearance error. In view of the above slight error, in the embodiment of the present invention, a user may press the first oil reservoir 503 by external pressure, so as to supply oil to the first hydraulic chamber 502 to maintain the pressure in the first hydraulic chamber 502 during the rightward movement of the first rotating roller 501, so that the arc-shaped plate 5093 may not contract, thereby ensuring that the other end of the film winding drum can be effectively fixed after the first rotating roller 501 is inserted, and achieving a better fixing effect.

In one embodiment of the present invention, an internally threaded sleeve 807 is fixedly mounted on the top inner wall of the rectangular groove 802 of the fire insulation aluminum-plastic panel production equipment, the internally threaded sleeve 807 penetrates through the rectangular column 801, and the screw 806 penetrates through the internally threaded sleeve 807 and is in threaded connection with the internally threaded sleeve 807.

Further, all seted up the spacing groove on the both sides inner wall of rectangular channel 802, equal slidable mounting has two stoppers in two spacing grooves, and four stoppers are close to each other one side all with rectangular block 803 fixed connection together. The circular groove has been seted up at the top of rectangular block 803, is equipped with the bearing in the circular groove, and the outer lane of bearing and the inner wall fixed connection of circular groove are in the same place, and screw rod 806 and the inner circle fixed connection of bearing are in the same place.

Through the technical scheme, according to the difference of the thickness of the aluminum-plastic plate, a user can rotate the screw rods 806 on the two lifting mechanisms 8, so that the positions of the rectangular blocks 803 driven by the screw rods 806 in the rectangular grooves 802 are changed, the working height of the pressing roller 9 is changed, and the laminating machine is suitable for laminating aluminum-plastic plates with different thicknesses.

The working principle is as follows: when the film rolling cylinder is installed, the valves on the first branch and the third branch of the fireproof heat-insulation aluminum-plastic plate production equipment are opened, the valves on the second branch and the fourth branch are closed simultaneously, the first rotating roller 501 is pushed to the left supporting frame 4, one end of the film rolling cylinder is placed on the second rotating roller 506, the first rotating roller 501 is continuously pushed to extrude the first oil storage bag 503 and the second oil storage bag 504 through the extrusion spring 5011, after the first oil storage bag 503 and the second oil storage bag 504 are pressurized, hydraulic oil enters the first oil path 505 and the second oil path 508 through the first branch and the third branch respectively, and then enters the first hydraulic chamber 502 and the second hydraulic chamber 507, so that the sliding plate 5091 in the tensioning unit 509 slides outwards under the action of the hydraulic oil, the arc-shaped plate 5093 is driven to move through the connecting rod 5092, so that the tensioning unit 509 on the second rotating roller 506 fixes one end of the film rolling cylinder, at this time, the first rotating roller 501 is stopped being pushed leftwards and the first rotating roller 501 is inserted into the other end of the film rolling cylinder rightwards, the baffles 5010 on the first rotating roller 501 and the second rotating roller 506 axially clamp the film winding drum; placing a plate on the plurality of power guide rollers 3, enabling one end of a protective film on the film winding drum to be attached to an aluminum-plastic plate to be coated with a film, then enabling the plurality of power guide rollers 3 to rotate towards the pressing roller 9, enabling the aluminum-plastic plate to drive the protective film to pass through the lower part of the portal frame 6, enabling the protective film to be completely adhered to the aluminum-plastic plate by softening the protective film by the plurality of hot air blowers 7, and then enabling the protective film and the aluminum-plastic plate to be completely integrated through extrusion of the pressing roller 9; according to the different thicknesses of the aluminum-plastic plates, a user can rotate the screws 806 on the two lifting mechanisms 8, so that the screws 806 can drive the rectangular blocks 803 to change in the positions of the rectangular grooves 802, the working height of the pressing roller 9 can be changed, and the laminating machine is suitable for laminating the aluminum-plastic plates with different thicknesses; when the film winding drum needs to be replaced, the valves on the second branch and the fourth branch are opened, the valves on the first branch and the third branch are closed at the same time, hydraulic oil in the first hydraulic cavity 502 and the second hydraulic cavity 507 respectively flows back to the first oil storage bag 503 and the second oil storage bag 504 through the second branch and the fourth branch through the first oil path 505 and the second oil path 508, at the moment, the tensioning unit 509 does not clamp the film winding drum any more, and a user pushes the first rotating roller 501 leftwards, so that the film winding drum can be conveniently and quickly taken down.
