[0030] A dust box 25 and an air pump 27 are fixed to the top of the base plate 1, a hose 24 is arranged between the outer side of the inner cavity 21 and the inner side of the dust box 25, an air inlet end of the air pump 27 is connected to a first pipe 26, an end of the first pipe 26 is connected to the inner side of the dust box 25, a second pipe 28 is connected to the air outlet end of the air pump 27, and an annular filter screen 32 is arranged inside the dust box 25 through a quick disassembly installation structure.

[0031] The quick-disassembly installation structure includes a locking circular plate 29, and the locking circular plate 29 is threadedly installed on the top of the dust box 25. A pressure plate 30 and an annular filter screen 32 are fixed to the top and bottom of the locking circular plate 29 respectively. A support ring 33 is fixed to the bottom of the annular filter screen 32, and a screw plate 31 is fixed to the top of the pressure plate 30, which ensures that when the locking circular plate 29 rotates, the locking circular plate 29 can be separated from the dust box 25, so that the annular filter screen 32 can be quickly removed from the dust box 25, which is convenient for disassembly and cleaning of the annular filter screen 32.

[0032] The bottom of the pressure plate 30 is located on the outside of the locking circular plate 29 and is fixed with a first rubber sealing ring 34. The bottom of the first rubber sealing ring 34 conflicts with the top of the dust box 25 to ensure the sealing of the connection between the pressure plate 30 and the dust box 25.

[0033] The movable plate 11 and the limiting rod 12 form a sliding structure, and a reciprocating thread is provided on the outer side of the vertical shaft 14 between the fixed plates 13. The vertical shaft 14 and the movable plate 11 are threadedly connected, ensuring that when the vertical shaft 14 rotates, the movable plate 11 can move back and forth up and down, so that the dust suction port 22 on the movable plate 11 can move back and forth up and down.

[0034] The dust suction ports 22 are evenly spaced on the inner side of the second through groove 20, and are symmetrically distributed about the central axis of the second through groove 20. The inner cavity 21 is designed as a "U" type structure, which ensures that suction can be generated on both sides of the wrapping film 9 at the same time, so that dust on both sides of the wrapping film 9 can be absorbed, ensuring the quality of dust removal of the wrapping film 9.

[0035] The first bevel gear 15, the second bevel gear 17 and the third bevel gear 18 have the same structure and are equal in size. The diameter of the fourth bevel gear 19 is larger than the diameters of the first bevel gear 15, the second bevel gear 17 and the third bevel gear 18, ensuring that the rotation speed of the vertical shaft 14 is greater than the rotation speed of the inflatable shaft 3, so that the paper tube 8 can wind the wrapping film 9 at a slower speed, and at the same time, the dust suction port 22 on the movable plate 11 can move up and down at a faster speed, so that the dust suction port 22 can absorb dust from one place of the wrapping film 9 multiple times, which is beneficial to the dust removal of the wrapping film 9 by the dust suction port 22.

[0036] Working principle: When using the dust collection device for stretch film processing, first Figure 1-2 As shown, the paper tube 8 is put on the inflatable shaft 3, and then the inflatable shaft 3 is inflated so that the inflatable shaft 3 fixes the paper tube 8 (the inflatable shaft 3 is an existing product and is not described in detail here), and then the end of the wrapping film 9 is glued to the paper tube 8, and the wrapping film 9 is wrapped according to Figure 1 Installed on two guide rollers 7, so that the wrapping film 9 between the two guide rollers 7 is in a vertical state, and the wrapping film 9 passes through the second through slot 20 on the movable plate 11;

[0037] according to Figure 1-4 As shown, when the servo motor 4 is started, the servo motor 4 drives the vertical shaft 14 to rotate through the air shaft 3, the fourth bevel gear 19, the third bevel gear 18, the horizontal shaft 16, the second bevel gear 17 and the first bevel gear 15. Since the movable plate 11 and the limit rod 12 constitute a sliding structure, and the outer side of the vertical shaft 14 is provided with a reciprocating thread between the fixed plate 13, and the vertical shaft 14 and the movable plate 11 are threadedly connected, the movable plate 11 reciprocates up and down, and the movable plate 11 drives the dust suction port 22 and the flexible brush 23 to reciprocate up and down at the same time, and the flexible brush 23 sweeps down the dust adsorbed on both sides of the wrapping film 9;

[0038] according to Figure 1As shown, the vacuum pump 27 is started, and the vacuum pump 27 makes the dust suction ports 22 located on both sides of the wrapping film 9 generate suction at the same time, and cooperates with the flexible brush 23 to sweep the dust adsorbed on both sides of the wrapping film 9, so that the dust enters the dust collecting box 25 through the dust suction port 22, the inner cavity 21 and the hose 24, and the dust is blocked by the annular filter 32, thereby preventing the dust from entering the production workshop and causing harm to the workers. Since the movable plate 11 drives the dust suction port 22 to move up and down, the dust suction port 22 can absorb dust from one place of the wrapping film 9 multiple times, which is conducive to the dust removal of the wrapping film 9 by the dust suction port 22;

[0039] according to Figure 5-6 When too much dust is adsorbed on the annular filter 32 and the annular filter 32 needs to be removed for cleaning, the screw plate 31 is rotated at this time, and then the screw plate 31 drives the locking circular plate 29 to rotate through the pressure plate 30. Since the locking circular plate 29 and the dust box 25 are threadedly connected, the locking circular plate 29 can be quickly removed from the dust box 25, thereby facilitating the annular filter 32 fixed at the bottom of the locking circular plate 29 to be quickly removed from the inside of the dust box 25 for cleaning.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
