[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The present invention provides a dust adsorption device for winding polyester film, including a body 1, openings 2 are provided at the top and bottom of the body 1, guide rollers 3 are rotatably provided on the surfaces of the two openings 2, two driving rods 4 are rotatably provided inside the body 1 through a driving mechanism, and a brush roller 5 is detachably installed on the surface of each driving rod 4, a collecting box 6 is fixedly provided inside the body 1, a through hole 7 is provided at the top of the collecting box 6, the collecting box 6 is arranged below the brush roller 5, a pipe 8 is movably provided on the surface of the collecting box 6, a push plate 9 is fixedly provided at one end of the pipe 8, and the push plate 9 is movably provided in the collecting box 6.

[0024] See also Figure 1 、 2And 3, the polyester film enters the body 1 from the top opening 2, leaves the body 1 from the bottom opening 2, and changes the conduction direction through the guide roller 3. When the polyester film is rolled up at the left end, the polyester film will move downward inside the body 1. At this time, the driving rod 4 can drive the brush roller 5 to rotate. With the polyester film as the axis of symmetry, the two brush rollers 5 rotate in opposite directions. The brush roller 5 on the left side of the polyester film rotates counterclockwise, and the brush roller 5 on the right side rotates clockwise. At this time, the brush roller 5 can drive the dust on the surface of the polyester film to move, so that it adheres to the surface of the brush roller 5 and falls into the collection box 6 due to extrusion when passing through the through hole 7. At this time, the polyester film is cleaned.

[0025] It should be noted that the brush roller 5 needs to be squeezed between the brush roller 5 and the top of the collection box 6 so that the bristles 17 on the surface of the brush roller 5 can be squeezed when passing through the through hole 7, and the bristles 17 can rebound when leaving the through hole 7 and shake off the dust on its surface into the collection box 6.

[0026] The driving mechanism includes two mutually meshing gears 10 and a motor 11 fixed to the body 1 . The output end of the motor 11 is connected to one of the driving rods 4 . The two gears 10 are fixed to one end of the two driving rods 4 , respectively.

[0027] See also Figure 1 and 2 The motor 11 can drive one of the driving rods 4 to rotate. When the driving rod 4 rotates, it can drive the other driving rod 4 to rotate through two mutually meshing gears 10, and the rotation directions of the two driving rods 4 are opposite, thereby realizing the driving of the two brush rollers 5.

[0028] A retaining ring 12 is fixedly provided on the surface of the pipe 8, and a spring 13 is fixedly installed between the retaining ring 12 and the body 1. The spring 13 is sleeved on the surface of the pipe 8. One end of the pipe 8 is connected to the negative pressure device. In this embodiment, the negative pressure device can be an industrial vacuum cleaner.

[0029] See also Figure 3 and 5 The negative pressure equipment can suck out the dust inside the collection box 6 through the pipe 8. When there is a lot of dust inside the collection box 6, the staff pushes the pipe 8 to make the pipe 8 move toward the inside of the body 1. At this time, the pipe 8 can drive the push plate 9 to move synchronously inside the collection box 6. The collection box 6 can cooperate with the push plate 9 to push and squeeze the dust, thereby reducing the floor space occupied by the dust so that the collection box 6 can accommodate more dust. After loosening the pipe 8, the pipe 8 can be reset under the action of the spring 13, and when pushing the pipe 8, it can also drive the push plate 9 close to the dust, so that the negative pressure equipment can absorb the dust.

[0030] The brush roller 5 is composed of two identical hollow rollers 16, the surface of the hollow roller 16 is provided with bristles 17, and a connecting part 18 is integrally formed at one end of the hollow roller 16. The connecting part 18 and the hollow roller 16 are both covered on the surface of the driving rod 4. The connecting part 18 is connected to the driving rod 4 through a connecting mechanism. The connecting mechanism includes a threaded rod 19, a connecting hole 20 and a locking cap 21. The threaded rod 19 is vertically fixed to the surface of the driving rod 4, the connecting hole 20 is provided on the surface of the connecting part 18, one end of the threaded rod 19 passes through the connecting hole 20, the locking cap 21 is threadedly connected to the surface of the threaded rod 19 and fits into the surface of the connecting part 18, the surface of the body 1 is hinged with a box door 14, and the surface of the body 1 is embedded with a window 15.

[0031] See also Figure 2 、 3 and 4, the capacity inside the collecting box 6 can be observed through the viewing window 15, and the box door 14 can protect the brush roller 5. After opening the box door 14, the locking cap 21 can be turned to make it fall off from the surface of the threaded rod 19. At this time, the hollow roller 16 can be directly removed from the surface of the driving rod 4, and the connecting part 18 drives the connecting hole 20 to disengage from the surface of the threaded rod 19. At this time, the hollow roller 16 can be removed from the inside of the body 1 to facilitate cleaning the brush roller 5 as a whole.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
