[0039] When using this utility model, first inject sufficient resin into the storage tank 15, then place the plastic packaging bag on the top wall of the workbench 4, then turn on the moving motor 5. The moving motor 5 drives the screw 6 to rotate, the screw 6 drives the threaded tube 7 to move to the right, the threaded tube 7 drives the moving plate 8 to move to the right, the moving plate 8 drives the sliding plate 14 to move to the right along the groove on the top wall of the tank 1, the sliding plate 14 drives the storage tank 15 to move to the right, and at the same time the moving plate 8 drives the connecting plate 9, the first electric telescopic rod 10 and the scraper 11 to move to the right; turn on the first electric telescopic rod 10, the first electric telescopic rod 10 drives the scraper 11 to move to the right. The resin is poured onto the plastic packaging bag until it comes into contact with the plastic packaging bag. Next, the solenoid valve on the discharge pipe 16 is opened, and the discharge pipe 16 moves to the right while pouring the resin onto the plastic packaging bag. At the same time, the scraper 11 coats the resin flowing onto the plastic packaging bag to prevent the resin from concentrating in one place, ensuring uniform coating and improving product quality. After coating, the scraper 11 is moved to the placement opening of the fixed plate 17 by the first electric telescopic rod 10. Then the cleaning motor 12 is turned on, and the cleaning motor 12 drives the cleaning plate 13 to rotate. The cleaning plate 13 scrapes off the residual resin on the scraper 11, making it easy to clean the scraper 11.

[0040] To prevent wrinkles in the plastic packaging bag, the second electric telescopic rod 20 is opened. The second electric telescopic rod 20 drives the lifting plate 21 to move down until the limiting plate 27 contacts the plastic packaging bag. Then, the limiting motor 22 is opened, and the limiting motor 22 drives the lead screw pair 23 to rotate. The lead screw nut block in the lead screw pair 23 drives the adjusting plate 26 to move from the middle to both sides. The adjusting plate 26 drives the guide block 25 to move along the guide post 24 to both sides. The adjusting plate 26 drives the limiting plate 27 to move to both sides. The limiting plate 27 flattens the plastic packaging bag from the middle to both sides. Finally, the limiting plate 27 moves to the edge of the plastic packaging bag and limits the plastic packaging bag to prevent wrinkles from occurring during coating.
