Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plastic bag packing tools, and in particular to an automatic plastic bag folding and packing machine. Background Technology
[0002] Plastic bags are used extensively as a common packaging medium in supermarket waste sorting bags, export waste sorting bags, food packaging, daily necessities retail, and medical consumables sorting. The subsequent folding and packing process of 5 or 10 bags per bag is a key link to ensure the storage, transportation, sale, and reuse of plastic bags. At present, most small and medium-sized enterprises in the market still use manual methods to complete the folding and packing of plastic bags: operators need to manually align the scattered plastic bags, fold them multiple times to form a fixed-size sheet structure, and then put the folded plastic bags one by one into the outer bag to complete the packing. The force and angle of manual folding are difficult to standardize, resulting in large differences in the neatness of the folded plastic bags. This can lead to problems such as inconsistent bag capacity and loose packaging during subsequent packing, affecting packaging quality. On the other hand, manual operation is inefficient. A skilled worker can only complete the folding and packing of a few thousand plastic bags per day, which is insufficient to meet the needs of large-scale production. Moreover, long hours of repetitive work can easily lead to operator fatigue, further reducing efficiency and increasing the error rate. Therefore, this application designs an automatic folding and packing machine for 5 or 10 easy-pull plastic bags to solve the above problems. Utility Model Content

[0017] Working Principle: In using this invention, firstly, a control panel for controlling the operation of each component is installed on the control console 1. Then, the device is powered on and debugged. Next, the inner bag and outer bag are placed on the inner bag support platform 2 and the outer bag support platform 6, respectively. The device is then started. During operation, the inner bag support platform 2 extends via an electric push cylinder until it engages with the pneumatic feeding rod 8. The pneumatic feeding rod 8 then starts, adsorbing and conveying the inner bag onto the adsorption conveyor belt 3. The adsorption conveyor belt 3 uses pneumatic adsorption to stably hold the inner bag on the conveyor belt for transport. When the inner bag is at the upper end of the pneumatic top plate 15, the pneumatic top plate 15 is pneumatically lifted. Then, the first sliding gripper 17 moves to the lifted position of the inner bag and clamps and pulls it, thus stably completing one fold of the inner bag. The first sliding gripper 17 then transfers the inner bag onto the folding support plate 10. The first sliding gripper 17 then supports the sliding... Simultaneously, the second inner bag is conveyed and lifted at the pneumatic top plate 15. The second sliding gripper clamps the inner bag and places it on the lifting support plate 11. The inner bag on the folding support plate 10 is folded twice by the downward pressure limit of the pressure plate and the folding of the rotating plate. Then, it is pushed to the second pressure support plate by the pusher assembly 13. The inner bag on the lifting support plate 11 is folded twice by the third sliding gripper with the same clamping and sliding working principle as the pneumatic top plate 15. Then, it is pushed to the second pressure support plate by the pusher assembly 13. The bag support box 14 is installed in the outer bag feeding assembly with the same working principle as the pneumatic feeding rod 8. When several folded inner bags are placed on the second pressure support plate, the vertical pusher plate is activated to descend and press the inner bags into the outer bags in the bag support box 14. Then, the outer bags fall and are sent out of the device by the discharge conveyor belt 7. The use of the device ends here.
