Description

[0002] The main reasons for laminating aluminum include protecting the surface, enhancing weather resistance, improving corrosion resistance, improving surface properties and extending service life. Laminating can be divided into double-sided laminating or single-sided laminating. For example, when laminating one side of an aluminum coil, the aluminum coil is formed by rolling up the aluminum material, and the polyethylene film and the aluminum material are bonded together by extruding the film. During lamination, a pressure roller is used to press the film so that when the film is attached to the aluminum coil, friction will occur between the pressure roller and the film due to contact between the pressure roller and the film, resulting in wear on the surface of the pressure roller. During lamination, the width of the aluminum coil will change, resulting in a change in the width of the laminating film. As a result, when laminating films of different widths, the pressure roller wears unevenly at both ends of the pressure roller, resulting in uneven pressure when the pressure roller applies pressure to the film. Excessive pressure in some areas will cause the material to be over-stretched, while insufficient pressure in other areas may cause the material to be unevenly compressed, resulting in wrinkles, affecting the laminating effect of the aluminum coil. Summary of the invention The purpose of the present invention is to solve the shortcomings of the prior art that wrinkles are easily generated during lamination, which affects the lamination effect, and to propose an aluminum material production lamination device.

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0015] Example 1: Reference Figure 1-7 A film coating device for aluminum production includes a support frame 1, on which a conveying roller 2 and a supporting roller 3 are rotatably connected through a bearing. A winding device is used to wind the aluminum material. The conveying roller 2 and the supporting roller 3 are driven by a motor to drive the aluminum material to move. The motor is installed on the support frame 1.

[0016] The support frame 1 is fixedly connected with a vertical plate 6, and a rotating column 10 is rotatably connected to the vertical plate 6 through a bearing, and a cross 15 is fixedly connected to the rotating column 10, and a plurality of rotating shafts 5 are rotatably connected to the cross 15 through a bearing, and a plurality of rotating shafts 5 are fixedly connected to pressure rollers 4, and the lengths of the plurality of pressure rollers 4 are not equal, and a gear 11 is fixedly connected to the rotating column 10, and a rack 12 is meshed with the gear 11, and the rack 12 is moved by a moving mechanism. Since the lengths of the plurality of pressure rollers 4 are different, the length of each pressure roller 4 corresponds to a polyethylene film of different widths, and when entering When polyethylene films of different widths are laminated, the rack 12 is moved by the moving mechanism, which drives the gear 11 to rotate, thereby driving the rotating column 10 to rotate, which will drive multiple pressure rollers 4 to rotate, and adjust the pressure roller 4 with the same width as the required lamination width to be directly above the support roller 3, ensuring that the surface of the pressure roller 4 is in contact with the film when laminating, so that the surface of the pressure roller 4 is evenly worn, and when the pressure roller 4 presses the polyethylene film, the pressure is uniform to avoid wrinkles, thereby ensuring the lamination effect on the aluminum material.

[0017] A motor 7 is fixedly connected to the vertical plate 6. The motor 7 is a low-speed motor. A second friction wheel 9 is fixedly connected to the output shaft of the motor 7. A first friction wheel 8 is fixedly connected to each of the plurality of rotating shafts 5. The first friction wheel 8 is in contact with the second friction wheel 9. The motor 7 rotates to drive the second friction wheel 9 to rotate, which in turn drives the first friction wheel 8 to rotate, which in turn drives the pressure roller 4 to rotate. The rotation direction of the pressure roller 4 is opposite to that of the support roller 3, thereby playing a conveying role.

[0018] A film roller 16 is rotatably connected to the support frame 1 via a bearing. The film roller 16 is provided with a polyethylene film. The film roller 16 is driven by a motor installed on the support frame 1. The film roller 16 rotates to loosen the polyethylene film for subsequent lamination.

[0019] The moving mechanism includes a threaded barrel 19, which is fixedly connected to the rack 12. A reciprocating threaded column 22 is connected to the inner thread of the threaded barrel 19. The reciprocating threaded column 22 is rotatably connected to the vertical plate 6 through a bearing. When the reciprocating threaded column 22 is used for adjustment, there is no need to perform forward and reverse rotation. A positioning sleeve 18 is fixedly connected to the rack 12. A positioning rod 17 is arranged in the positioning sleeve 18. The positioning rod 17 is fixedly connected to the vertical plate 6. By rotating the reciprocating threaded column 22, the position of the reciprocating threaded column 22 in the threaded barrel 19 is adjusted, thereby driving the rack 12 to move. The positioning rod 17 and the positioning sleeve 18 limit the rack 12, prevent the rack 12 from shifting, and ensure that the rack 12 is always engaged with the gear 11.

[0020] Example 2: In Example 1, when polyethylene films of different widths are laminated, a pressure roller 4 of a length corresponding to the width is used. When adjusting, the pressure roller 4 is easily offset, and it is impossible to ensure that the pressure roller 4 is exactly above the support roller 3, so that the pressure roller 4 cannot apply pressure to the film, affecting the lamination effect. Figure 1-9 , as another preferred embodiment of the present invention, based on Example 1.

[0021] A plurality of positioning holes 14 are provided at equal intervals on the circumference of the rotating column 10, and the number of the positioning holes 14 is equal to the number of the pressure rollers 4. A limiting sleeve 23 is fixedly connected to the vertical plate 6, and a positioning column 20 is arranged in the limiting sleeve 23. A first spring 21 is fixedly connected to the lower end of the positioning column 20, and a fixing ear is fixedly connected to the first spring 21, and the fixing ear is fixedly connected to the vertical plate 6. By adopting the positioning column 20 to cooperate with the positioning hole 14, when the positioning column 20 is inserted into the positioning hole 14, it will ensure that the adjusted pressure roller 4 is just above the support roller 3, thereby ensuring the accuracy of the adjustment.

[0022] The positioning column 20 extends into the positioning hole 14, and a connecting plate 32 is fixedly connected to the positioning column 20, and an abutment rod 25 is fixedly connected to the connecting plate 32. A slideway 26 is provided on the reciprocating threaded column 22, and the slideway 26 is spiral. A slider is slidably arranged in the slideway 26, and a rotating ring 13 is fixedly connected to the slider, and the rotating ring 13 abuts against the abutment rod 25. By rotating the rotating ring 13 clockwise, the slider will be driven to slide in the slideway 26. At the same time, during the sliding process, the height of the rotating ring 13 will be reduced, which will push the abutment rod 25. The connecting plate 32 is driven to move downward, so that the positioning column 20 moves downward and the positioning column 20 is disengaged from the positioning hole 14. When the slider moves to the lowermost end, it abuts against the slideway 26. When the rotating ring 13 is rotated, the reciprocating threaded column 22 is driven to rotate, thereby driving the rotating column 10 to rotate and adjusting the position of the pressure roller 4. The pressure roller 4 can be adjusted by only rotating the rotating ring 13, and there is no need to manually press the positioning column 20 to disengage from the positioning hole 14. This is conducive to the convenience of operation and at the same time ensures the accuracy of the position adjustment of the pressure roller 4.

[0023] A connecting rib 24 is provided through the connecting plate 32 , and the connecting rib 24 is fixedly connected to the fixing ear. The connecting rib 24 serves to limit the connecting plate 32 , thereby preventing the connecting plate 32 from rotating.

[0024] During operation, the aluminum material is placed on the conveying roller 2 and the supporting roller 3, and the aluminum material is rolled up by the winding device through the winding mechanism. The film roller 16 rotates to loosen the polyethylene film. When the polyethylene film is attached to the aluminum material, the distance between the pressure roller 4 and the supporting roller 3 is less than the total thickness of the polyethylene film and the aluminum material. When it passes, the polyethylene film is pressed onto the aluminum material. When polyethylene film of different widths needs to be coated, the sliding block is driven to slide in the slideway 26 by rotating the rotating ring 13 clockwise. At the same time, during the sliding process, the height of the rotating ring 13 is reduced, which pushes the abutment rod 25, and drives the connecting plate 32 to move downward. The positioning column 20 is moved downward, and the positioning column 20 is separated from the positioning hole 14. When the slider moves to the lowermost end, it abuts against the slideway 26. When the rotating ring 13 is rotated, the reciprocating threaded column 22 is driven to rotate, thereby driving the rotating column 10 to rotate, and the position of the pressure roller 4 is adjusted. When the pressure roller 4 with a length equal to that of the polyethylene film is located directly above the support roller 3, the rotating ring 13 is released. Under the action of the restoring force of the first spring 21, the positioning column 20 is inserted into the positioning hole 14 to fix the position of the pressure roller 4. Subsequently, the motor 7 is driven to drive the second friction wheel 9 to rotate, and the first friction wheel 8 to rotate, which will drive the pressure roller 4 to rotate, and the film is pressed and conveyed.

[0025] Embodiment 3: In Embodiment 2, after the positioning column 20 is aligned with the positioning hole, when the rotating ring 13 is loosened, under the action of the restoring force of the first spring 21, there is an upward force on the rotating ring 13, and the rotating ring 13 drives the slider to slide in the slideway 26, so that the rotating ring 13 rotates and rises. Since the reciprocating threaded column 22 adopts a bearing connection, when the rotating ring 13 rotates and rises, there is friction between the slider and the slideway 26, which easily drives the reciprocating threaded column 22 to rotate slightly in the opposite direction, causing the rotating column 10 to rotate slightly, causing the positioning column 20 and the positioning hole 14 to be offset, resulting in the positioning column 20 being unable to be inserted into the positioning hole 14.

[0026] Reference Figure 1-10As another preferred embodiment of the present invention, on the basis of embodiment 2, a fixing ring 27 is fixedly connected to the vertical plate 6, a connecting plate 28 is fixedly connected to the reciprocating threaded column 22, a plurality of abutment blocks 31 are rotatably connected to the fixing ring 27 through a pin shaft, a plurality of fixing blocks 30 are fixedly connected to the fixing ring 27 at equal distances, a second spring 29 is fixedly connected to the plurality of fixing blocks 30, the plurality of second springs 29 are respectively abutted against the plurality of abutment blocks 31, and the plurality of abutment blocks 31 are in contact with the connecting plate 28. By using the plurality of abutment blocks 31 to cooperate with the second springs 29, when the positive rotation is forward, the plurality of fixing blocks 30 are fixedly connected to the fixing ring 27, and the plurality of fixing blocks 30 are fixedly connected to the second springs 29. The reciprocating threaded column 22, that is, rotating clockwise, will drive the abutment block 31 to rotate slightly around the pin shaft, and reset under the action of the restoring force of the second spring 29. When rotating in the opposite direction, the abutment block 31 will abut against the connecting disk 28. When the abutment block 31 rotates, the rotating disk 28 is stuck, preventing the connecting disk 28 from reversing, so that the reciprocating threaded column 22 can only rotate in the forward direction, avoiding the situation where the reciprocating threaded column 22 rotates in the opposite direction when the rotating ring 13 is loosened, thereby ensuring the alignment of the positioning column 20 with the positioning hole 14, so that the positioning column 20 can be inserted into the positioning hole 14 when stopping.

[0027] A wear-resistant layer is provided on the connection disk 28 . The wear-resistant layer is made of wear-resistant steel material, which improves the wear resistance of the connection disk 28 .
