Description

Technical Field

[0001] This utility model relates to the field of woven bag inner film technology, and in particular to an automatic inner film covering device for waterproof and sealing woven bags. Background Technology

[0002] Plastic woven bags are made of warp and weft weave, and their moisture-proof and leak-proof effects are poor. Therefore, the goods inside plastic woven bags are prone to deterioration. Generally, an inner bag is placed inside the plastic woven bag to improve the overall waterproof performance of the plastic woven bag.

[0003] When applying the inner lining, the woven bag is first opened, then the inner lining is opened, and the inner lining is fed into the woven bag through an inserting rod or inserting plate. Currently, the woven bag is usually opened manually, which is inefficient and increases the labor force. To solve the above problems, an automatic inner lining device for waterproof and sealing woven bags that can automatically open the woven bag is provided. Utility Model Content

[0007] Preferably, a conveyor roller is movably connected to the inner side of the fixed frame, and the conveyor roller drives the adsorption conveyor belt to move in a specific direction.

[0008] Preferably, the adsorption conveyor belt is provided with a vacuum plate inside, and the negative pressure holes on the vacuum plate correspond to the adsorption holes.

[0009] Preferably, a vacuum pump and a negative pressure pipe are provided below the fixing frame, and the vacuum pump is connected to the vacuum plate through the negative pressure pipe.

[0010] Preferably, the side wall of the fixing frame is provided with an air outlet pipe, and an air inlet is opened on the air outlet pipe, with the air inlet opening facing the opening of the woven bag.

[0011] Preferably, the mounting frame is equipped with a fan and a ventilation duct, and the fan is connected to the air outlet pipe through the ventilation duct.

[0012] Preferably, an inserting assembly is fixedly connected to the outer wall of the fixing frame for automatically inserting the inner membrane into the woven bag.

[0013] Preferably, the fitting assembly includes a second cylinder mounted on a fixed frame, and the output end of the second cylinder is connected to a fitting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The woven bag is moved to a stop below the opening assembly. The first cylinder is activated, which drives the negative pressure suction cup to move downward. The negative pressure suction cup uses negative pressure to attract the upward side of the woven bag. The first cylinder is retracted, and together with the vacuum plate, it attracts the downward side of the woven bag, which can open the woven bag and make it easy to fit the inner wall of the woven bag.

[0016] 2. At the same time as the woven bag is opened, start the fan and blow air through the blower onto the woven bag. This can further increase the opening of the woven bag and make it easier for the inner wall to enter the woven bag.

[0017] 3. Place the inner film of the woven bag on the insertion plate. The second cylinder pushes the push plate to move, thereby pushing the inner film on the insertion plate to send the inner film into the woven bag. After that, the second cylinder retracts, and the bag is put on automatically, which can realize the inner film of the woven bag and improve the efficiency of inner film putting.

[0018] In summary, this utility model overcomes the shortcomings of the prior art, has a reasonable design, automatically conveys woven bags and opens them to facilitate the entry of the inner film, and has high social use value and application prospects. Attached Figure Description
