Description

Technical Field

[0001] The utility model relates to the technical field of mouth openers, in particular to a mouth opener for woven bags. Background Art

[0002] Woven bags, also known as snakeskin bags, are a type of plastic. Their raw materials are various chemical plastic raw materials such as polyethylene and polypropylene. When storing agricultural products, woven bags are generally used for storage and transportation. When such larger woven bags are used to hold agricultural products, two people are often required to open the opening of the woven bag. For this reason, corresponding openers have appeared, and the existing openers have a single function, which can only open the opening of the woven bag. Agricultural products are placed for a long time and there is still a certain amount of moisture. The existing openers cannot remove the moisture, thus affecting their quality.

[0003] After searching, a Chinese patent with publication number CN211167613U discloses a mouth opener for woven bags. When rice or wheat is poured into the woven bag, the weight gradually increases, causing it to squeeze the T-shaped slide plate downward, and the T-shaped slide plate compresses the return spring downward. In addition, the T-shaped slide plate drives the slide plate to move downward through the connecting rod, thereby squeezing the air in the rectangular chamber into the second air guide hole, and then enters the open column, the hollow tube and the third air guide hole in turn, thereby achieving the purpose of dehumidifying the rice or wheat, thereby ensuring its quality, and achieving the purpose of opening the woven bag, by pulling out the plug in the socket, and then adjusting the height of the hollow tube, when it reaches the required height, the plug is inserted into the socket of the open column and the socket of the hollow tube, thereby achieving the purpose of adjusting the height, which is suitable for woven bags of different lengths, thereby improving its practicality.

[0004] However, when this structure is actually used, the corners of the woven bag are placed between the lower end of the pressure block and the lower end of the recess, the sliding rod is loosened, and the corners of the woven bag are clamped by the pressure of the compression spring mounted on the sliding rod. When more and more raw materials are loaded inside the woven bag, as the weight of the woven bag increases, the pressure of the compression spring alone can easily cause the woven bag to fall off, causing the woven bag to tip over, affecting the use effect.
