Description

Technical Field

[0001] This utility model relates to the field of woven bags, and mainly to a woven bag edge-sealing device. Background Technology

[0002] Currently, woven bags, as a packaging material, are mainly produced by extruding plastic raw materials into film, cutting, and unidirectionally stretching them into flat filaments, which are then woven together to form woven bags with open ends. Finally, the bottom edges are folded and sewn to seal the finished woven bag; for example, CN206799901U discloses such a woven bag edge-sealing machine. However, with social development and expanding customer demands, the thickness and strength of some woven bags have significantly increased compared to existing woven bags, and traditional stitching edge-sealing can no longer meet these requirements. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a woven bag edge-binding device and assembly method.

[0004] A woven bag edge-sealing device includes a frame, on which a feeding component for feeding woven bags and an edge-sealing component for edge sealing are mounted. The feeding component includes a feeding tray with a limiting edge on its edge, the limiting space formed by the limiting edge being adapted to the size of the woven bag. It also includes a vertical plate, on which the feeding tray is mounted and can slide along a guide groove. It also includes a pushing cylinder, which is fixedly connected to the feeding tray. The pushing cylinder can drive the feeding tray to move along the guide groove, and the feeding tray can be driven to the bottom of the edge-sealing component.

[0005] Preferably, the edge-binding assembly includes a fixed cylinder fixedly installed on the top surface of the frame. The piston rod of the fixed cylinder is connected to a fixed plate. A floating plate is connected to the bottom of the fixed plate via a first connecting rod, and an edge-binding fixture is connected via a second connecting rod. The edge-binding fixture, the floating plate, and the fixed plate are connected by a sliding connection that allows them to move up and down. Support springs are fitted on both the first and second connecting rods. One end of the support spring is supported on the fixed plate, and the other end is supported on the floating plate and the edge-binding fixture.

[0006] Preferably, the fixing plate has multiple wire holes, and the wires are connected to the edge-binding fixture. The edge-binding fixture is equipped with a heating unit, and the lower end of the edge-binding fixture is equipped with an annular heating plate, which is used to provide heat for edge-binding the woven bag.

[0007] Preferably, the inner ring of the heating plate is provided with air holes, and the edge-sealing fixture is provided with air ducts, which can blow air through the air holes.

[0008] Preferably, the central area enclosed by the heating plate has a groove structure.

[0009] Preferably, the edge of the limiting edge has an opening structure that facilitates the taking and putting in of the woven bag.

[0010] Compared with existing technologies, this solution has the following advantages: The edge-sealing equipment in this solution heats and softens the inside of the woven bag edge to melt and bond it, thus providing an integrated edge-sealing structure. Furthermore, the blowing structure facilitates separation and cooling after completion, making it convenient for subsequent handling of the woven bags. Attached Figure Description

Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0016] Example 1

[0017] A woven bag edge-sealing device includes a frame 1, on which a feeding assembly 2 for feeding woven bags and an edge-sealing assembly 3 for edge sealing are mounted. The feeding assembly 2 includes a feeding tray 4 with a limiting edge 5 on its edge. The limiting space formed by the limiting edge 5 is adapted to the size of the woven bag. It also includes a vertical plate 6, on which the feeding tray 4 is mounted and can slide along a guide groove 7. Furthermore, it includes a pushing cylinder 8, which is fixedly connected to the feeding tray 4 and can drive the feeding tray 4 to move along the guide groove 7, allowing the feeding tray 4 to be moved below the edge-sealing assembly 3. The edge-sealing technology in this solution uses heat bonding to ensure overall reliability.

[0018] The edge-binding assembly 3 includes a fixed cylinder 9 fixedly mounted on the top surface of the frame 1. The piston rod of the fixed cylinder 9 is connected to a fixed plate 10. A floating plate 11 is connected to the bottom of the fixed plate 10 via a first connecting rod, and an edge-binding fixture 12 is connected via a second connecting rod. The edge-binding fixture 12, the floating plate 11, and the fixed plate 10 are connected by a sliding connection that allows them to move up and down. A support spring 13 is fitted on both the first and second connecting rods. One end of the support spring 13 is supported on the fixed plate 10, and the other end is supported on the floating plate 11 and the edge-binding fixture 12. The floating plate 11 has a through hole in the middle, through which the lower end of the edge-binding fixture 12 protrudes. During operation, the fixed plate 10 moves downward, pushing the floating plate 11 and the edge-sealing fixture 12 to move synchronously. When the edge-sealing fixture 12 contacts the woven bag placed on the feeding tray 4, the fixed plate 10 continues to move downward. At this time, the floating plate 11 and the edge-sealing fixture 12 stop moving downward, and the spring is in a compressed state. Then, the heating plate 14 heats the edge of the woven bag to complete the edge-sealing work. Then, the blowing function is activated.

[0019] In this design, the fixing plate 10 has multiple wire holes, and wires are connected to the edge-sealing fixture 12. A heating unit is installed inside the edge-sealing fixture 12, and a ring-shaped heating plate 14 is located at the lower end of the fixture 12. The heating plate 14 provides heat for edge-sealing the woven bag. The heating power can be set to avoid excessively high or low temperatures, and the edge-sealing fixture 12 ensures reliable connection. This structural design guarantees reliable heating.

[0020] The heating plate 14 has air holes 15 on its inner ring, and the edge-sealing fixture 12 has an air duct that can blow air through the air holes 15. After heating, the edge-sealing area may stick due to the high temperature. The air holes 15 can cool the edge-sealing area and provide downward pressure to ensure the heating plate 14 and the woven bag separate.

[0021] The central area enclosed by the heating plate 14 is a groove structure 16. The groove structure 16 can prevent the central area of ​​the woven bag from being heated and stuck together. The edge of the limiting edge 5 has an opening structure 17 for easy handling of the woven bag. The edge-sealing device in this solution heats and softens the inside of the woven bag to melt and bond it, thereby providing an integrated edge-sealing structure. Moreover, after completion, the blowing structure facilitates separation and cooling, making it convenient for subsequent handling of the woven bag.

[0022] Example 2

[0023] The difference between this embodiment and embodiment 1 is that a partition strip is provided in the middle of the feeding tray 4 to divide the feeding tray 4 into two areas.

[0024] Example 3

[0025] The difference between this embodiment and embodiment 1 is that: the bottom of the feeding tray 4 is provided with a through hole, and a sensor is provided below the through hole. The sensor detects whether there is a woven bag in the feeding tray 4 through the through hole.
