Technical Field

[0001] This invention relates to the field of aluminum sheet production equipment technology, and more particularly to aluminum sheet coating rollers. Background Technology

[0002] After aluminum sheets are formed, they require multiple processes such as cutting, grinding, and packaging. To prevent scratches on the surface of the aluminum sheets during subsequent processing, which could affect product quality, a film needs to be applied to the surface. A common film-applying device is shown in patent publication number CN115157646A, entitled "A Film-Applying Equipment for Aluminum Sheet Surfaces." The film is attached to the profile surface using adhesive. Using a strong adhesive will affect subsequent removal; using a weak adhesive will affect the adhesion effect. Therefore, it is necessary to improve existing film-applying methods and devices. Summary of the Invention

[0023] The following combination Figures 1 to 5 The principles and features of the present invention are described, and the examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0024] An aluminum sheet coating roller includes a roller body 1, a first coating roller 3, and a second coating roller 4.

[0025] The roller body 1 includes an outer cylinder 5 and a mandrel 6, which are coaxially arranged, with the mandrel 6 located inside the outer cylinder 5. A rib 7 is provided between the mandrel 6 and the outer cylinder 5, with one end of the rib 7 extending to the outer surface of the mandrel 6 and the other end extending to the inner surface of the outer cylinder 5. The outer cylinder 5 and the mandrel 6 are relatively fixed together by the rib 7. The rib 7 extends radially along the roller body 1, and multiple ribs 7 are arranged in a circumferential array.

[0026] The mandrel 6 has guide rods 8 at both ends, which extend radially along the mandrel 6 and are arranged in a circumferential array. Each guide rod 8 has a guide groove 9, which also extends radially along the mandrel 6. A guide block 10 is slidably connected within the guide groove 9. A first glue-applying roller 3 and a second glue-applying roller 4 are connected between the guide blocks 10 at both ends, and are alternately distributed. The outer cylinder 5 has grooves 2 arranged in a circumferential array, with the guide rods 8 distributed at both ends of the grooves 2. The guide blocks 10 slide up and down, which can drive the first glue-applying roller 3 and the second glue-applying roller 4 to move up and down. The first glue-applying roller 3 and the second glue-applying roller 4 can protrude from the surface of the outer cylinder 5 when moving upwards; they can also be completely retracted into the grooves 2 when moving downwards. It is worth noting that the first glue-applying roller 3 and the second glue-applying roller 4 alternately protrude from the surface of the outer cylinder 5 or are retracted into the groove 2. That is, if the first glue-applying roller 3 is retracted into the groove 2, the second glue-applying roller 4 protrudes from the surface of the outer cylinder 5; if the first glue-applying roller 3 protrudes from the surface of the outer cylinder 5, the second glue-applying roller 4 is completely retracted into the groove 2.

[0027] A drive wheel 12 is rotatably connected inside the spindle 6, and a traction wire 20 connects the drive wheel 12 and the guide block 10. Meanwhile, a spring 11 is provided in the guide groove 9, and under the action of the spring 11, the guide block 10 tends to move away from the center of the spindle 6. The drive wheel 12 reciprocates between two adjacent guide rods 8: when the drive wheel 12 rotates to one side, the guide block 10 connected to the first glue-applying roller 3 is dragged by the traction wire 20, thereby completely retracting the first glue-applying roller 3 into the groove 2; the traction wire 20 of the adjacent guide block 10 (which is connected to the second glue-applying roller 4) becomes longer, and under the action of the spring 11, the guide block 10 slides upward, thereby causing the second glue-applying roller 4 to protrude from the surface of the outer cylinder 5; when the drive wheel 12 rotates to the opposite side, the traction wire 20 on the guide block 10 connected to the first glue-applying roller 3 becomes longer, and under the action of the spring 11, the guide block 10 slides upward, thereby causing the first glue-applying roller 3 to protrude from the surface of the outer cylinder 5; the traction wire 20 of the adjacent guide block 10 (which is connected to the second glue-applying roller 4) becomes shorter, and the guide block 10 causes the second glue-applying roller 4 to be completely retracted downward into the groove 2. The two ends of the spindle 6 are rotatably connected to the bracket 16. The bracket 16 is connected to a clutch 17. One end of the clutch 17 is connected to the drive shaft 18, and the other end can be fixed or separated from the drive wheel 12. An electromagnet 19 is also provided inside the spindle 6. The electromagnet 19 and the clutch 17 are respectively located on both sides of the drive wheel 12. The electromagnet 19 and the clutch 17 are alternately fixed relative to the drive wheel 12. When the drive wheel 12 needs to be rotated, the electromagnet 19 is de-energized, the clutch 17 is fixed relative to the drive wheel 12, and the drive shaft 18 drives the drive wheel 12 to rotate through the clutch 17. When the drive wheel 12 does not need to be rotated, the electromagnet 19 is energized, the clutch 17 is disengaged from the drive wheel 12, and the electromagnet 19 attracts the drive wheel 12, making the drive wheel 12 fixed relative to the spindle 6.

[0028] The groove 2 has receiving slots 13 on both sides, and a protective plate 14 is slidably connected within the receiving slot 13. The protective plate 14 can be completely housed in the receiving slot 13 or slide out of the receiving slot 13 to close the groove 2. Specifically, a connecting rod 15 connects the guide block 10 and the protective plate 14. The up and down movement of the guide block 10 can be controlled by the connecting rod 15 to slide the protective plate 14. When the guide block 10 slides downward, the connecting rod 15 pulls the protective plate 14, causing the protective plate 14 to slide out and close the groove 2; when the guide block 10 slides upward, the connecting rod 15 pushes the protective plate 14, causing the protective plate 14 to slide into the receiving slot 13 and open the groove 2.

[0029] When using this device, if a strong adhesive needs to be applied to the film, the first adhesive roller 3 protrudes from the surface of the roller body 1, and the second adhesive roller 4 is housed in the groove 2 to pick up the adhesive. If a weak adhesive needs to be applied to the film, the second adhesive roller 4 protrudes from the surface of the roller body 1, and the first adhesive roller 3 is housed in the groove 2 to pick up the adhesive.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
