[0023] In this embodiment, Figure 1 As shown, the housing assembly 1 includes a base 101 , four corners of the bottom end of the base 101 are provided with support legs 102 , and a through hole 103 is opened in the middle of the bottom end of the base 101 .

[0024] In this embodiment, Figure 2As shown, the dust collecting box 3 and the dust suction pump 4 are connected to the feed port 5 via a connecting pipe, so as to screen the dust impurities mixed in the plastic packaging bag raw materials and prevent the dust impurities from entering the feeding bin 2 along with the plastic packaging bag raw materials.

[0025] In this embodiment, Figure 1 As shown, the inner bottom end of the feed port 5 is set as an inclined structure; the convenience of the dust-free feeding device for plastic packaging bags during use is greatly improved, the problem of dust and impurities easily entering the feeding bin 2 due to manual feeding is solved, the labor intensity of workers is reduced, and the product quality of plastic packaging bags is improved.

[0026] In this embodiment, Figure 1 As shown, the top of the pressing plate 10 is configured as an inclined structure, so that the plastic packaging bag raw material at the top of the pressing plate 10 can be discharged from the discharge port 9 more smoothly.

[0027] In this embodiment, Figure 2 As shown, the guide rod 11 and the charging bin 2 are set to be in sliding connection, which increases the stability of the pressing plate 10 during movement, thereby preventing the pressing plate 10 from being offset or tilted during movement.

[0028] In this embodiment, Figure 4 As shown, the baffle 15 rotates with the central axis of the connecting rod 14 as the center of the circle, thereby preventing external dust and impurities from entering the interior of the feeding bin 2 through the feed port 5, thereby meeting people's demand for dust-free feeding in the production of plastic packaging bags.

[0029] The use method and advantages of the utility model: When the dust-free feeding device for producing ton bags is used, the working process is as follows:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the base 101 is placed at a designated position through the support legs 102, and then the feeding bin 2 is placed inside the base 101, and then the dust suction pump 4 is started to work through the controller, and then the raw materials of the plastic packaging bag are poured in through the feed port 5. After the raw materials of the plastic packaging bag enter the inside of the feed port 5, under the action of the dust suction pump 4, the dust impurities mixed in the raw materials of the plastic packaging bag are sucked in, so that the dust impurities pass through the first filter screen 6 and the connecting pipe into the inside of the dust collecting box 3. At this time, when the raw materials of the plastic packaging bag fall to the bottom end of the inside of the feed port 5, the second filter screen 7 filters the remaining dust impurities in the raw materials of the plastic packaging bag, so that the filtered dust impurities pass through the second filter screen 7 and enter the inside of the dust collecting box 8. The double filtration realizes the screening of the dust impurities mixed in the raw materials of the plastic packaging bag, and prevents the dust impurities from entering the inside of the feeding bin 2 together with the raw materials of the plastic packaging bag, thereby meeting people's demand for dust-free feeding in the production of plastic packaging bags. The filtered raw materials of the plastic packaging bag use their own gravity to push the baffle 15, so that the baffle 15 takes the central axis of the connecting rod 14 as The center of the circle rotates, and the baffle 15 is used to prevent external dust and impurities from entering the interior of the feeding bin 2 through the feeding port 5. At this time, the plastic packaging bag raw materials fall to the top of the pressing plate 10 inside the feeding bin 2. As the plastic packaging bag raw materials inside the feeding bin 2 increase, the gravity of the plastic packaging bag raw materials themselves is used to drive the pressing plate 10 to move downward with the cooperation of the guide rod 11. At this time, the pressing plate 10 compresses the spring 12. When the plastic packaging bag raw materials inside the feeding bin 2 reach the required amount, stop feeding into the feeding port 5, and then cover it. The cover plate at the top of the feed port 5, and then the solenoid valve outside the discharge port 9 is opened through the controller. As the plastic packaging bag raw materials are discharged from the discharge port 9, the pressure plate 10 drives the guide rod 11 to slowly move upward and reset under the elastic structure of the spring 12, which greatly improves the convenience of the dust-free feeding device for plastic packaging bags during use, solves the problem that dust and impurities can easily enter the feeding bin 2 due to manual feeding, reduces the labor intensity of workers, thereby improving the product quality of plastic packaging bags, and meeting the dust-free feeding requirements of plastic packaging bag production.
