Description

Technical Field

[0001] This utility model belongs to the field of plastic woven bag processing technology, specifically relating to a stacking device for plastic woven bags. Background Technology

[0002] Plastic woven bags are packaging containers made primarily from resins such as polypropylene and polyethylene. These resins are extruded and stretched into flat filaments, which are then woven using a warp and weft weaving process. Their structure consists of a dense mesh formed by interwoven flat filaments, possessing both toughness and wear resistance. They are widely used in chemical, agricultural, and logistics industries for containing powdery or solid materials.

[0003] After the woven bags are produced and processed, they need to be packaged. During packaging, the woven bags need to be stacked flat one by one to ensure neatness when the bags are collected. One such device, CN221836416U, is a stacking device for plastic woven bags. This technical solution improves upon existing technology and can neatly stack woven bags of different models, thus expanding its applicability to some extent. While this solution ensures neat stacking, further binding and packaging requires loosening the compressed woven bags, resulting in looseness between the bags and a less tight packaging. Utility Model Content

[0017] The following are specific implementation cases and appendices. Figures 1-4 This utility model will be further described, but it is not limited to these embodiments. This utility model provides a technical solution: a stacking device for plastic woven bags, comprising: a stacking base plate 1, four sliding holes on the upper wall of the stacking base plate 1, a stacking support structure installed inside the four sliding holes of the stacking base plate 1, a pressing structure installed on the upper wall of the stacking base plate 1, and two locking structures installed on the lower wall of the pressing structure; the stacking support structure includes: four stacking slide rods 2, two stacking support plates 3, four stacking springs 4, and two stacking... The four stacking slides 2 are movably installed inside the sliding holes of the stacking base plate 1. The two stacking support plates 3 are respectively installed on the upper wall of the four stacking slides 2. The two ends of the four stacking springs 4 are respectively installed on the upper wall of the stacking base plate 1 and the lower wall of the stacking support plate 3. The two stacking restriction plates 5 are respectively installed on the lower wall of the four stacking slides 2. The upper wall of the stacking base plate 1 is equipped with four restriction slots 13. The side wall of the restriction slots 13 is equipped with fixing buckles 14. The lower wall of the stacking base plate 1 is equipped with four raising brackets 15.

[0018] As a preferred embodiment, the pressing structure further includes: two pressing seats 6, two pressing frames 7, two pressing plates 8, and a pressing handle 9; the two pressing seats 6 are respectively installed on the rear wall of the stacking base plate 1, the two pressing frames 7 are respectively installed on the upper wall of the pressing seats 6 by hinges, the two pressing plates 8 are respectively installed on the lower wall of the pressing frames 7, and the pressing handle 9 is installed on the front wall of the two pressing frames 7.

[0019] As a preferred embodiment, the two locking structures further include: a movable buckle 10, two movable locking seats 11, and a movable pull rod 12; the movable buckle 10 is installed on the inner wall of the lower pressure frame 7, the two movable locking seats 11 are respectively installed on the lower wall of the lower pressure handle 9, the movable pull rod 12 is movably installed inside the two movable locking seats 11, and the movable pull rod 12 is installed on the front wall of the movable buckle 10, and the tail of the two movable pull rods 12 is equipped with a pull rod handle 16.

[0020] Working principle:

[0021] 1. Pressing and Stacking: The operator first places the flattened plastic woven bags on the upper wall of the two stacking support plates 3. When the number of plastic woven bags stacked reaches the predetermined standard, the four stacking springs 4 will be compressed by the weight of the plastic woven bags. The four stacking slide rods 2 slide downward in the sliding holes of the stacking base plate 1. The two stacking limiting plates 5 can connect the four stacking slide rods 2, allowing the four stacking slide rods 2 to move downward synchronously, which in turn drives the two stacking support plates 3 to move downward in the four limiting slots 13. Then, the operator holds the pressing handle 9, allowing the two pressing frames 7 to rotate downward around the two pressing seats 6 as the axis until the two pressing plates 8 are parallel and the movable buckle 10 and the fixed buckle 14 are engaged, allowing the two stacking support plates 3 and the two pressing plates 8 to squeeze the plastic woven bags.

[0022] II. Binding Operation: After completing the above pressing operation, the operator uses the packaging straps of the plastic woven bag to bind the compressed woven bag, bypassing the gaps between the two stacked support plates 3 and the gaps between the two pressing plates 8, thus completing the packaging of the plastic woven bag. Next, the operator pulls the movable lever 12 through the lever handle 16, causing the movable buckle 10 to disengage from the fixed buckle 14. At this time, the two pressing plates 8 flip upwards around the hinges on the two pressing seats 6, allowing the operator to remove the bound and packaged plastic woven bag, thus enabling the next packaging operation.
