[0023] 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 of the embodiments.

[0024] Example 1

[0025] Reference Figure 1-6 A surface dust removal device for PE film comprises a mounting plate 1 and a dust removal roller 6. A main rotating shaft 2 is rotatably provided in the middle of the mounting plate 1. Auxiliary rotating shafts 3 are rotatably installed at both ends of the mounting plate 1. A synchronous component is commonly provided at one end of the auxiliary rotating shaft 3. A mounting disk 4 is fixed at one end of the auxiliary rotating shaft 3 away from the synchronous component. A plurality of mounting brackets 5 are distributed on the circumference of a side surface of the mounting disk 4 away from the auxiliary rotating shaft 3 with the axis of the auxiliary rotating shaft 3 as the center. The dust removal roller 6 is arranged on the side of the mounting bracket 5 away from the center of the mounting disk 4. Threaded rods 7 are fixed at both ends of the lower side of the mounting plate 1. A plurality of counterweight rings 8 are sleeved on the middle part of the rod body of the threaded rod 7. A locking cap 9 is threadedly installed at the lower end of the threaded rod 7.

[0026] Example 2

[0027] Reference Figure 1-6 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0028] The two ends of the upper side of the mounting plate 1 are both provided with locking screws 10 through threaded holes. One end of the locking screw 10 located inside the mounting plate 1 cooperates with the secondary rotating shaft 3. The setting of the locking screw 10 allows personnel to fix the secondary rotating shaft 3, that is, to prevent the secondary rotating shaft 3 from rotating automatically during use, so that when personnel do not actively adjust, only half or one-third of the dust removal rollers 6 are always in contact with the PE film, so as to facilitate the subsequent replacement of the dust removal rollers 6; the secondary rotating shaft 3 is located inside the mounting plate 1. A contact ring 11 with a frosted outer ring surface is provided in the middle of the body, and the end of the locking screw 10 abuts against the outer ring surface of the contact ring 11. The setting of the contact ring 11 makes the locking screw 10 provide a better locking effect on the secondary rotating shaft 3, that is, the secondary rotating shaft 3 is less likely to rotate by itself; the cross-section of the end of the locking screw 10 located outside the mounting plate 1 is hexagonal, and the inside of the end of the locking screw 10 located outside the mounting plate 1 is provided with a hexagonal bolt hole. The setting of the hexagonal bolt hole makes it easy for people to rotate the locking screw 10.

[0029] The synchronous component includes two synchronous wheels 12 and a synchronous belt 13. The synchronous wheels 12 are respectively installed at one end of the two secondary rotating shafts 3 away from the mounting plate 4. The synchronous belt 13 is connected to the two synchronous wheels 12. The setting of the synchronous component enables personnel to rotate one of the secondary rotating shafts 3. Driven by the two synchronous wheels 12 and the synchronous belt 13, the other secondary rotating shaft 3 can rotate synchronously, thereby facilitating personnel to quickly switch the dust removal roller 6 in contact with the PE film, and also facilitating personnel to save the locking screw 10, that is, personnel only need one locking screw 10 to fix the two secondary rotating shafts 3; a base 15 is rotatably installed at one end of the main rotating shaft 2 located outside the mounting plate 1, and a mounting hole is provided at the lower end of the base 15. The setting of the base 15 facilitates the installation and fixation of the device; sliding grooves are provided at both ends of the mounting plate 1 facing the mounting plate 4, and the mounting plate 4 is provided with a matching guide rail 14 corresponding to the sliding groove. The setting of the sliding groove and the guide rail 14 facilitates the stability of the mounting plate 4 during rotation.

[0030] Principle and advantages of use: During use of the utility model, the mounting plate 1 is in a free rotation state under the action of the main rotating shaft 2, and then each dust removal roller 6 is installed on the mounting frame 5 respectively. At this time, the PE film can be passed through the dust removal roller 6 between the two mounting plates 4, and the number of counterweight rings 8 on the two threaded rods 7 is further adjusted according to specific use requirements, so that the mounting plate 1 is in a state of different weights at both ends, so that the heavier end of the mounting plate 1 drives the dust removal roller 6 at this end to push the PE film downward, and the lighter end of the mounting plate 1 pushes the PE film upward, thereby making the upper and lower sides of the PE film both contact with multiple dust removal rollers 6, and then when the PE film flows through the device, the upper and lower side surfaces of the PE film contact with multiple dust removal rollers 6, so that the upper and lower side surfaces of the PE film are cleaned by the dust removal rollers 6, that is, when this scheme is used, not only the upper and lower side surfaces of the PE film can be cleaned, but also at least two dust removal rollers 6 on each side can be cleaned at the same time, thereby compared with the traditional scheme, this scheme effectively improves the cleaning effect.

[0031] Furthermore, in the above process, as shown in the attached figure of the present invention, when the number of dust removal rollers 6 on each mounting plate 4 is six, only two or three dust removal rollers 6 are in contact with the PE film, that is, personnel can disassemble and install the remaining dust removal rollers 6, so that when the device is in use, when the dust removal rollers 6 need to be replaced or maintained, the personnel do not need to stop the device for a long time, that is, they only need to rotate the secondary rotating shaft 3 to move the idle dust removal rollers 6 until they are in contact with the PE film, which further improves the working efficiency of the device when in use; in summary, compared with the traditional solution, the present solution not only does not require manual force, but also is convenient to use. The dust removal roller 6 can be made to contact with the PE film, which reduces the manpower consumption, and by changing the number of counterweight rings 8, the contact pressure between the dust removal roller 6 and the PE film can be adjusted, and under the action of the mounting plate 4, the number of dust removal rollers 6 in contact with the PE film is increased, which not only can clean the upper and lower surfaces of the PE film, but also at least two dust removal rollers 6 on each side can be cleaned at the same time. Therefore, compared with the traditional scheme, this scheme effectively improves the cleaning effect and cleaning efficiency, and under the action of the secondary rotating shaft 3, the downtime of the dust removal roller 6 during maintenance can be effectively shortened, which makes this scheme not only more convenient to use, but also has high cleaning efficiency.

[0032] It should be further explained that the setting of the locking screw 10 allows personnel to fix the auxiliary rotating shaft 3, that is, to prevent the auxiliary rotating shaft 3 from rotating on its own during use, so that when personnel do not actively adjust it, only half or one-third of the dust removal rollers 6 are always in contact with the PE film, thereby facilitating the subsequent replacement of the dust removal rollers 6; the setting of the contact ring 11 makes the locking screw 10 provide a better locking effect on the auxiliary rotating shaft 3, that is, the auxiliary rotating shaft 3 is less likely to rotate on its own; the setting of the synchronization component allows personnel to fix one of the auxiliary rotating shafts When the shaft 3 rotates, driven by the two synchronous wheels 12 and the synchronous belt 13, the other secondary rotating shaft 3 can rotate synchronously, so that it is convenient for personnel to quickly switch the dust removal roller 6 in contact with the PE film, and it is also convenient to save personnel locking screws 10, that is, personnel only need one locking screw 10 to fix the two secondary rotating shafts 3; the setting of the base 15 facilitates the installation and fixation of the device; the two ends of the mounting plate 1 facing the mounting disk 4 are provided with slide grooves, and the setting of the slide grooves and guide rails 14 facilitates the stability of the mounting disk 4 during rotation.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
