This process, through the washing dust collector, rotating roller, film material, scraper, water inlet, water outlet, and drying component, forms a dust removal structure for the packaging bag film. This structure effectively conducts static electricity from the film material surface to the ground and removes dust from the film material surface. It solves the problem of dust adsorbed by static electricity, which leads to surface dirt on the film material.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4 As shown in the figure, a dust removal device for food packaging bag production according to an embodiment of the present invention includes a water washing dust removal box 1 and a film material 12. A pair of rotating rollers 11 are rotatably connected to the inner wall of the water washing dust removal box 1, arranged symmetrically on the inner wall of the water washing dust removal box 1. The film material 12 passes through the outer walls of the pair of rotating rollers 11. A scraper 13 is fixedly connected to the inner wall of the water washing dust removal box 1 near the film material 12. The scraper 13 is arranged on the inner wall of the water washing dust removal box 1. Yes, and they are symmetrically arranged. A water inlet 14 is fixedly connected to the outer wall of the washing dust collector 1, and a water outlet 15 is fixedly connected to the outer wall of the washing dust collector 1 away from the water inlet 14. A drying assembly is provided at the top of the washing dust collector 1 away from the scraper 13. A partition assembly is provided inside the washing dust collector 1, and a sewage discharge assembly is provided at the bottom of the washing dust collector 1. An air collection assembly is provided in the washing dust collector 1 through the drying assembly. During operation, the washing dust collector 1 is installed between the packaging bag conveyor roller and the printing machine, and the film material 12 passes through... The rotating roller 11 moves inside the washing and dust removal box 1. A water pump connected to the inlet 14 adds clean water to the washing and dust removal box 1. The outlet 15 is connected to a grounded sewage tank. The film material 12 comes into contact with the clean water, and the static electricity on the film material 12 is conducted to the ground through the outlet 15. The film material 12 moves inside the washing and dust removal box 1. The scraper 13 scrapes off the dust adhering to the surface of the film material 12. The drying assembly dries the surface of the film material 12. This step, through the arrangement of the washing and dust removal box 1, rotating roller 11, film material 12, scraper 13, inlet 14, outlet 15, and drying assembly, forms a dust removal structure for the packaging bag film. This achieves the function of conducting static electricity on the surface of the film material 12 to the ground and removing dust from the surface of the film material 12. It solves the problem of dust adsorption on the film material 12 due to static electricity, which leads to surface dirt on the film material 12. It reduces the amount of static electricity on the surface of the film material 12, reduces dust adhesion to the surface of the film material 12, and improves the cleanliness of the surface of the film material 12.

[0024] like Figure 2 and Figure 3As shown, the drying assembly includes a fixing plate 2, a fixing frame 21, nozzles 22, and a water distribution pipe 23. The fixing plate 2 is fixedly connected to the outer wall of the washing and dust removal box 1 near the water inlet 14. A pair of fixing plates 2 are arranged symmetrically on the outer wall of the washing and dust removal box 1. The fixing frame 21 is fixedly connected between the pair of fixing plates 2. The nozzles 22 are fixedly connected to the middle of the fixing frame 21. Multiple sets of nozzles 22 are arranged symmetrically in the middle of the fixing frame 21. The output ends of the multiple sets of nozzles 22 are inclined towards the film material 12. The water distribution pipe 23 is fixedly connected to a set of nozzles 22. At the end of nozzle 22, during operation, when the film material 12 is being conveyed, the water distribution pipe 23 is connected to an external air compressor. Compressed air is sprayed out through nozzle 22 to blow off water droplets and dust from the surface of the film material 12. This step, through the arrangement of fixing plate 2, fixing frame 21, nozzle 22 and water distribution pipe 23, forms a surface drying structure for the film material 12, realizing the function of blowing air onto the surface of the film material 12, solving the problem of water droplets or dust adhering to the surface of the film material 12, improving the dryness of the film material 12, and facilitating the implementation of subsequent printing steps.

[0025] like Figure 2 As shown, the partition assembly includes a partition plate 3 and a through groove 31. The partition plate 3 is fixedly connected to the inner wall of the washing dust collector 1 near the water inlet 14. The through groove 31 is opened in the middle of the partition plate 3 near the membrane material 12. During operation, the partition plate 3 divides the interior of the washing dust collector 1 into two chambers. Clean water flows from the water inlet 14 to the chamber of the washing dust collector 1 near the water inlet 14, and flows through the through groove 31 to the chamber of the washing dust collector 1 near the water outlet 15, thus making the washing dust collector 1 closer to the water inlet 14. The water pressure in the chamber of water inlet 14 is greater than the water pressure in the chamber of the washing dust collector 1 near the water outlet 15. This step, through the setting of the partition plate 3 and the through groove 31, forms a partition structure, which realizes the division of the interior of the washing dust collector 1 into high water pressure and low water pressure chambers. This solves the problem of impurities in the chamber of the washing dust collector 1 near the water outlet 15 flowing to the chamber of the washing dust collector 1 near the water inlet 14, reducing the situation of impurities adhering to the surface of the membrane material 12, and improving the cleanliness of the surface of the membrane material 12.

[0026] like Figure 3 As shown, the air collecting assembly includes an air collecting plate 4, which is hinged to the bottom of the fixed frame 21. A pair of air collecting plates 4 are arranged symmetrically at the bottom of the fixed frame 21. During operation, the air collecting plates 4 are rotated to bring them closer to the film material 12, reducing the gap between the pair of air collecting plates 4 and increasing the air velocity of the nozzle 22. This step, through the arrangement of the air collecting plates 4, forms an air collecting structure, realizing the function of concentrating the airflow, increasing the airflow speed, and improving the dryness of the surface of the film material 12.

[0027] like Figure 4As shown, the sewage discharge assembly includes a first sewage discharge valve 5, a second sewage discharge valve 51, and a filter plate 52. The first sewage discharge valve 5 is fixedly connected to the bottom of the washing dust removal box 1 near the inlet 14. The second sewage discharge valve 51 is fixedly connected to the bottom of the washing dust removal box 1 near the outlet 15. The filter plate 52 is fixedly connected to the inner wall of the washing dust removal box 1 near the rotating roller 11. During operation, dust adhering to the surface of the membrane material 12 falls into the washing dust removal box 1 and falls to the bottom of the washing dust removal box 1 through the filter plate 52. When sewage discharge is required, the first sewage discharge valve 5 and the second sewage discharge valve 51 are opened to discharge the impurities at the bottom of the washing dust removal box 1. This step, through the arrangement of the first sewage discharge valve 5, the second sewage discharge valve 51, and the filter plate 52, forms a sewage discharge structure, realizing the function of discharging impurities at the bottom of the washing dust removal box 1 and reducing the situation where the settled impurities float on the top of the filter plate 52.

[0028] like Figure 1 As shown, the bottom of the washing dust collector 1 is fixedly connected to a support leg 6. Multiple sets of support legs 6 are set at the bottom of the washing dust collector 1 and are evenly distributed at the four corners of the bottom of the washing dust collector 1. The bottom end of the support leg 6 is fixedly connected to a foot pad 61. During operation, the support leg 6 supports and fixes the washing dust collector 1, and the foot pad 61 increases the stability of the device during operation. This step, through the setting of the support leg 6 and the foot pad 61, forms a support structure, improves the stability of the device during operation, and reduces the possibility of the device tipping over.

[0029] like Figure 2 As shown, the partition plate 3 is made of stainless steel. During operation, the use of stainless steel reduces the likelihood of rust and corrosion, thus extending the service life of the partition plate 3.

[0030] During operation, the washing and dust removal box 1 is installed between the packaging bag conveyor roller and the printing machine. The film material 12 moves inside the washing and dust removal box 1 via the rotating roller 11. A water pump connected to the inlet 14 adds clean water to the washing and dust removal box 1, and the outlet 15 is connected to a grounded sewage tank. The film material 12 comes into contact with the clean water, and static electricity on the film material 12 is conducted to the ground through the outlet 15. As the film material 12 moves inside the washing and dust removal box 1, the scraper 13 scrapes off the dust adhering to the surface of the film material 12. The drying assembly dries the surface of the film material 12. During conveying, the water distribution pipe 23 is connected to an air compressor, and compressed air is sprayed through the nozzle 22 to blow off water droplets and dust from the surface of the film material 12. The partition plate 3 divides the interior of the washing and dust removal box 1 into two chambers. Clean water flows from the inlet 14 towards the chambers near the washing and dust removal box 1. The water inlet 14 flows through the channel 31 to the chamber near the outlet 15 of the washing dust collector 1, making the water pressure in the chamber near the inlet 14 greater than that in the chamber near the outlet 15. The air collecting plate 4 is rotated to bring it closer to the membrane material 12, reducing the gap between the pair of air collecting plates 4 and increasing the air velocity of the nozzle 22. Dust adhering to the surface of the membrane material 12 falls into the washing dust collector 1 and falls to the bottom of the washing dust collector 1 through the filter plate 52. When sewage needs to be discharged, the first sewage valve 5 and the second sewage valve 51 are opened to discharge the impurities at the bottom of the washing dust collector 1. The support leg 6 supports and fixes the washing dust collector 1, and the foot pad 61 increases the stability of the device during operation. The partition plate 3 is made of stainless steel to reduce the rust and corrosion of the partition plate 3 and improve its service life.
