The ends of the rotating frame 4-9 are fixed with side frames 4-11 and movable wheels 4. -12 is rotatably arranged on the side frame 4-11.

[0027] Working principle: The staff first pulls the clamping disc 2-6 to move forward to separate the right end of the clamping disc 2-6 from the unwinding rod 2-2, and places the rolled film on the unwinding rod 2-2. Next, the worker puts the right end of the clamping plate 2-6 back on the unwinding rod 2-2, and the clamping plate 2-6 and the fixing plate 2-3 cooperate with each other to limit the position of the rolled film. Since the position of the clamping plate 2-6 on the unwinding rod 2-2 can be adjusted, the rolls of different widths can be placed on the unwinding rod 2-2, which is convenient to meet the requirements of different widths of aluminum plates. The film needs; then the staff places the aluminum plate on the base 1, and pulls one end of the film to be in close contact with the right end of the aluminum plate. After all the preparations are done, the worker first starts the motor 4-3 to rotate counterclockwise, and then pushes the aluminum plate to move to the right, the aluminum plate will continuously pull out the film from the film roll. When in contact, the first movable roller 3-3 can cover the film on the aluminum plate, and can perform the initial horizontal flattening operation on the laminated film, so as to preliminarily deal with some air bubbles generated when the film is applied.

[0028] The staff continues to push the aluminum plate to the bottom of the pressing roller 4-10, the motor 4-3 will drive one of the power gears 4-6 to rotate counterclockwise through the power shaft 4-4, and one of the power gears 4-6 will pass through the other meshed with it. The power gear 4-6 will drive the sliding ring 4-5, the rotating shaft one 4-7 and the guide bar 4-8 to rotate clockwise, the rotating shaft one 4-7 and the guide bar 4-8 can drive the rotating frame 4-9 clockwise Rotating, the rotating frame 4-9 will drive the four pressing rollers 4-10 to rotate clockwise. At this time, the four pressing rollers 4-10 can flatten the film in all directions, so that the film and the aluminum plate can be more flattened. Lamination can further eliminate the bubbles generated after the film is applied, and at the same time, some bubbles located on the edge of the aluminum plate can also be eliminated. When the aluminum plate is pushed to be in contact with the second movable roller 3-3, the second movable roller 3-3 can horizontally flatten the film covered on the aluminum plate again, so that the film can adhere to the aluminum plate. It is tighter to prevent the film from falling off during later handling, and it can also completely eliminate the bubbles generated when the film is applied. When an aluminum plate is covered with film, the staff needs to cut off the film.

[0029] Example 2

[0030] On the basis of Example 1, as figure 1 and Figure 4 As shown, the adjusting mechanism 5 for adjusting the height of the rotating frame 4-9 is provided on the bottom side of the sliding ring 4-5, and the adjusting mechanism 5 includes a clamping seat 5-1 and a bolt 5-2. A bolt fixed on the bottom side of the bottom of the sliding ring 4-5 and located below the support frame 4-1, a bolt hole is provided at the lower end of the socket 5-1, and the bolt 5-2 is rotatably arranged on the socket 5-1 In the hole, one end of the bolt 5-2 can be in contact with the threaded hole on the rotating shaft 1 4-7. The bolt 5-2 is used to support and limit the rotating shaft 1 4-7. The bolt 5-2 is connected to the rotating shaft. A 4-7 coordination can adjust the position of the rotating frame 4-9, which is beneficial to the lamination and flattening operation of aluminum plates with different thicknesses.

[0031] Working principle: In order to cover different thicknesses of aluminum plates, the staff can adjust the height of the rotating frame 4-9 according to the thickness of the aluminum plate before filming the aluminum plate, so that the four pressing rollers 4-10 Can be in contact with the upper surface of aluminum plates of different thicknesses. The staff rotates the bolt 5-2 to separate it from the threaded hole on the rotating shaft one 4-7, and then pulls the rotating shaft one 4-7 to move up, which will push the rotating shaft one 4-7 to move down. When the rotating shaft 1 4-7 moves upward, it will drive the guide bar 4-8, the rotating frame 4-9 and the pressing roller 4-10 to move upward. At this time, the distance between the pressing roller 4-10 and the base 1 will increase. , suitable for lamination processing of thicker aluminum plates; when the rotating shaft 1 4-7 moves down, it will drive the guide bar 4-8, the rotating frame 4-9 and the pressure roller 4-10 to move down. At this time, the pressure roller The distance between 4-10 and the base 1 will be reduced, which is suitable for lamination processing of thinner aluminum plates. After the height of the rotating frame 4-9 is adjusted, the staff needs to turn the bolts 5-2 into the corresponding threaded holes, so that the bolts 5-2 can limit the position of the rotating shaft 1 4-7. Since the telescopic rod 3-2 can drive the movable roller 3-3 to move up and down, the height of the movable roller 3-3 can be automatically adjusted when the aluminum plates with different thicknesses are pushed to contact the movable roller 3-3, so as to meet the requirements of different aluminum plates. Lamination needs.

A connecting rod 6-12 is rotatably connected between the bottom of the push frame 6-11 and the turntable 6-10, and the turntable 6 -10 Through the connecting rod 6-12, the push frame 6-11 can be driven to reciprocate left and right.

[0034] Working principle: The power shaft 4-4 will drive the transmission shaft 6-1 and the missing bevel gear 6-3 to rotate clockwise through the two bevel gears 1 6-2.
