Description

Horizontal woven bag automatic compression and packaging device Technical Field

[0001] This utility model belongs to the field of horizontal woven bag packaging technology, and specifically relates to an automatic compression packaging device for horizontal woven bags. Background Technology

[0002] Woven bags are made primarily from chemical plastics, which are extruded and stretched into flat filaments, then woven, braided, and bagged. Existing woven bag compression equipment suffers from problems such as uneven compression density, the need for manual assistance in bagging, and the inability to integrate compression and sealing. Currently, traditional equipment mostly adopts a vertical structure, which is difficult to adapt to standard woven bag sealing, resulting in high labor costs and low operating efficiency. Summary of the Invention

[0003] To address the aforementioned technical problems, this utility model provides a horizontal woven bag automatic compression and packaging device, which solves the problem that existing equipment mostly adopts a vertical structure, making it difficult to adapt to standard woven bag packaging, resulting in high labor costs and low operating efficiency.

[0004] The automatic compression and packaging device for horizontal woven bags provided by this utility model includes a horizontal frame, with the lower front side of the horizontal frame extending forward, and a first motor fixedly installed above the extension; a feeding compression unit is fixedly mounted on the front side of the horizontal frame; the front side of the feeding compression unit is integrally provided with a flat and elongated flared opening, and two sets of unidirectional biting gears are rotatably arranged on the rear side of the inside of the feeding compression unit; the first motor and the unidirectional biting gears are connected by a belt drive; the tightening and forming unit includes a rotating screwing tube and a spiral fin, and the rotating screwing tube is rotatably arranged inside the horizontal frame in conjunction with a bearing.

[0005] Furthermore, the rotating screw tube is internally fixed with three sets of spiral fins, the height of which is 1 / 6 to 1 / 4 of the tube diameter, and the spiral angle of which is 25° to 35°.

[0006] Furthermore, a locking clamp is fixedly installed on the middle rear side of the horizontal frame, and a pre-installed woven bag is fixedly installed on the outside of the locking clamp. The inner lining of the locking clamp is an anti-slip rubber strip.

[0007] Furthermore, a second motor is fixedly installed in the lower middle of the horizontal frame, and the second motor is connected to the rotating screwing tube by a chain.

[0008] Furthermore, a rotating baffle is hinged to the rear side of the interior of the horizontal frame, and a buckle is fixedly installed on the rear side of the rotating baffle.

[0009] Furthermore, a rotating support rod is rotatably provided at the rear bottom of the horizontal frame, and a spring lock is rotatably provided above the rotating support rod, with the spring lock interlocking with the buckle.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The feeding funnel design of this utility model: The flat rectangular cross-section, combined with the 15°-30° inclination angle of the lower plate, forms a flow channel that is narrower at the top and wider at the bottom, allowing the loose woven bag to slide naturally under the action of gravity and the inclined surface. The symmetrical guard plates on both sides prevent material deviation and improve feeding smoothness. The design of the upper plate being half the length of the lower plate balances opening compatibility and material gathering effect, reducing manual handling procedures.

[0012] 2. The safe meshing of the biting gear in this utility model: The tooth profile of the unidirectional rotating gear is blunted to avoid cutting the woven bag. At the same time, the mechanical force of gear meshing will "bite" the bag and bring it in, realizing automated initial compression. Compared with traditional manual feeding, the efficiency is increased by more than 30%, and the bag breakage rate is reduced.

[0013] Therefore, this utility model has the positive effects of better adapting to standard woven bag packaging, saving labor costs, and improving work efficiency. Attached Figure Description
