Description

Technical Field

[0001] The utility model belongs to the technical field of packaging equipment, in particular to a dust removal device for packaging bags. Background Art

[0002] During the production process of packaging bags, dust, impurities, and other contaminants often adhere to their surfaces. These contaminants not only affect the appearance of the bags but may also contaminate the contents. Traditional dust removal methods often rely on manual wiping or simple air blowing. Manual wiping is inefficient and difficult to ensure consistent cleanliness. Existing packaging bag dust removal devices can meet basic dust removal needs, but during dust removal, dust in the air can be re-adsorbed onto the bags, resulting in incomplete cleaning and affecting subsequent processing.

[0003] After searching, the Chinese patent document (authorization announcement number CN215745068U) shows that the utility model discloses a surface dust removal device for food packaging bag production, including a box body, a bag inlet is opened at the lower end of the left side wall of the box body, a bag outlet is opened at the lower end of the right side wall of the box body, and telescopic components are installed at both ends of the inner cavity of the box body. The utility model removes dust and other impurities on the surface of the food packaging bag by arranging a spraying component and a cleaning component to ensure the effect of subsequent food packaging bags. When the packaging bag passes through the dust removal box, the water pump is started to pump clean water from the inner cavity of the water tank into the spray box through the water guide pipe. The inner cavity of the seat is then sprayed out through the nozzle to clean the upper and lower surfaces of the packaging bag. At the same time, the packaging bag continues to be conveyed. When passing through the cleaning component, the cleaning brush can stick to the surface of the packaging bag, which is convenient for cleaning the dust and water stains on the packaging bag, thereby achieving a better cleaning effect. The sewage finally flows into the inner cavity of the water tank again through the water hole, is filtered through the filter, and can be recycled again to save water resources. This device can meet basic dust removal needs, but when cleaning the dust, the dust in the air will be adsorbed on the packaging bag again, and the cleaning is not thorough enough, affecting subsequent processing. Utility Model Content

[0004] The purpose of the utility model is to provide a packaging bag dust removal device to solve the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a packaging bag dust removal device, comprising a cleaning wheel for dust removal, a side panel is provided on the side of the cleaning wheel, a dust removal box is connected to the side of the side panel, an air inlet is provided on the top of the dust removal box, a fan is installed inside the air inlet, a filter frame is installed on the inner top of the dust removal box, an arc-shaped filter plate is provided inside the filter frame, a sealing cover is provided on the outer periphery of the filter frame, an upper air outlet is connected to the bottom of the sealing cover for drying and cleaning the packaging bag, a ventilation port is provided on the side of the sealing cover, a ventilation pipe is connected to the side of the ventilation pipe, a lower air outlet is installed on the end of the ventilation pipe away from the ventilation port, and a sealing cover for removing the arc-shaped filter plate is provided on the top of the dust removal box.

[0006] Preferably, a first telescopic rod is installed inside the side plate, a hollow column is installed at the movable portion of the first telescopic rod, and a spring is provided inside the hollow column.

[0007] Preferably, one end of the spring away from the first telescopic rod is connected to a support column, one end of the support column away from the hollow column is connected to a bearing, and a rotating shaft is installed on the movable part of the bearing.

[0008] Preferably, an inlet for the packaging bags to enter is provided on one side of the dust removal box, and an outlet is provided on the other side of the dust removal box.

[0009] Preferably, a cleaning box is provided on the vertical inner wall of the dust removal box, and a spray head for spraying cleaning liquid is installed on the vertical inner wall of the cleaning box.

[0010] Preferably, a second telescopic rod is installed on the transverse inner wall of the cleaning box, a scraper is installed on the movable part of the second telescopic rod, a liquid inlet is provided at the bottom of the cleaning box, and a cleaning liquid recovery tank is installed at the bottom of the cleaning box.

[0011] Preferably, a packaging bag roller is provided on one side of the dust removal box, and a packaging bag recovery wheel is provided on the other side of the dust removal box, and support frames are installed on the sides of the packaging bag roller and the packaging bag recovery wheel.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are:

[0013] The packaging bag dust removal device benefits from the structure of the filter frame and the curved filter plate. When the fan is turned on, air enters the interior of the filter frame through the air inlet. A portion of the filtered air passes through the curved filter plate and the upper air outlet to dry and clean the upper surface of the packaging bag. The other portion of the filtered air enters the ventilation pipe through the vent and is ejected from the lower air outlet to dry and clean the lower surface of the packaging bag. Compared with the existing device that directly brings air into contact with the cleaned packaging bag, this structure can filter impurities in the air and prevent dust in the air from being adsorbed on the packaging bag again, making the cleaning more thorough and reducing the impact of dust on subsequent processing.

[0014] Thanks to the structure of the cleaning wheel, the two hollow columns of this packaging bag dust removal device move closer to the middle, and the hollow columns drive the support column and the bearing to move. The bearing drives the rotating shaft and the cleaning wheel to gradually move closer. The cleaning wheel contacts the packaging bag and cleans the surface of the packaging bag. This structure can adapt to the contact pressure between the cleaning wheel and the surface of the packaging bag to prevent the cleaning wheel from squeezing the packaging bag too tightly or insufficient contact, causing the packaging bag to deform or not clean properly.
