Description

Technical Field

[0001] The utility model relates to the technical field related to packaging bag filling, and more particularly to a device for automatically cleaning dust from packaging bags. Background Art

[0002] Filling is a form of packaging that protects and identifies products by placing liquids or granular materials into containers. As a form of packaging, filling plays a crucial role in the production process. First, it effectively protects products from contamination and damage, improving their quality and safety. Second, filling enables standardized production, improving efficiency and reducing costs. Furthermore, filling provides attractive packaging and labeling, attracting consumers and enhancing product competitiveness.

[0003] Existing bagged products fall onto the conveyor belt after being filled by the air-blowing packaging machine. They are then transported to the palletizer via the conveyor belt and stacked into ton bags. They are then forked into the finished product storage area by a forklift. Due to the dust on the surface of the bags during the bagging and canning process, which affects the clarity of the subsequent inkjet coding and the packaging image, we have proposed a device that automatically cleans the dust from the packaging bags to solve the above problems. Utility Model Content

A purge air nozzle 5 is installed at the bottom of the pulse tube 4. A high-pressure air pump 6 is installed on the outside of the dust hood 3 through a support frame. A connecting pipe 7 is conductively connected between the air supply end of the high-pressure air pump 6 and the end of the pulse tube 4 extending to the outside of the dust hood 3.

[0033] A proximity switch 8 is mounted on the bottom wall of the inner cavity of the dust collection hood 3 through a bracket;

[0034] A control host 9 is installed on the outer wall of the dust collection cover 3 away from the high-pressure air pump 6;

[0035] A dust collector 10 is provided at one end of the conveyor belt 1, and a corrugated connecting hose 11 is connected between the air inlet end of the dust collector 10 and the top end of the dust cover 3;

[0036] It should be noted that when the device for automatically cleaning dust in the packaging bag is in use, the bagged product falls onto the conveyor belt 1 after being filled by the air-blowing packaging machine. When the product moves to the inner side of the dust hood 3 installed at the end of the conveyor belt 1, the proximity switch 8 recognizes the bagged product and transmits the signal to the control host 9. The control host 9 sends instructions to make the high-pressure air pump 6 and the vacuum cleaner 10 work respectively. The high-pressure air pump 6 delivers the high-pressure gas to the pulse tube 4 through the connecting pipe 7, and then blows the dust on the surface of the bagged product through the blowing nozzle 5. The dust raised during the blowing process is sucked into the vacuum cleaner 10 through the corrugated connecting hose 11. Finally, the bagged product falls on the palletizer 2 and is transported, which solves the dust on the packaging bag and ensures the clarity of the subsequent coding and the packaging image.

[0037] like Figure 3 As shown, the end of the pulse tube 4 away from the high-pressure air pump 6 is arranged in a closed structure;

[0038] A plurality of pulse tubes 4 are equidistantly arranged on the inner side of the dust collecting cover 3 corresponding to the conveying direction of the conveyor belt 1, and a plurality of purge air nozzles 5 are equidistantly arranged in the axial position of the pulse tube 4;

[0039] It should be noted that the blowing area can be effectively increased, thereby improving the blowing effect on the surface of the bagged product.

[0041] It should be noted that the dust raised during the blowing process is sucked into the vacuum cleaner 10 through the corrugated connecting hose 11, which avoids the raising of a large amount of dust and provides a good working environment for the staff.

[0042] like Figure 1 、 Figure 2 As shown, a feeding port is provided on the side of the dust hood 3 corresponding to the conveyor belt 1, and a discharging port is provided on the side of the dust hood 3 corresponding to the palletizer 2;

[0043] It should be noted that this is beneficial for the bagged products to be fed into and discharged through the dust hood 3 .

[0044] like Figure 2 、 Figure 3 As shown, the detection end of the proximity switch 8 corresponds to the end of the conveyor belt 1, the output end of the proximity switch 8 is electrically connected to the input end of the control host 9, and the output end of the control host 9 is electrically connected to the output ends of the high-pressure air pump 6 and the vacuum cleaner 10 respectively;

[0045] It should be noted that the model of the proximity switch 8 can be M30, and the model of the control host 9 can be L4125-IT-17CM.

[0046] During use: the bagged product is filled by the air-blowing packaging machine and falls onto the conveyor belt 1. When the product moves to the inner side of the dust hood 3 installed at the end of the conveyor belt 1, the proximity switch 8 recognizes the bagged product and transmits the signal to the control host 9. The control host 9 sends instructions to make the high-pressure air pump 6 and the vacuum cleaner 10 work respectively. The high-pressure air pump 6 delivers the high-pressure gas to the pulse tube 4 through the connecting pipe 7, and then blows the dust on the surface of the bagged product through the blowing nozzle 5. The dust raised during the blowing process is sucked into the vacuum cleaner 10 through the corrugated connecting hose 11. Finally, the bagged product falls on the palletizer 2 and is conveyed.
