Description

Technical Field

[0001] The utility model belongs to the technical field of ton bag edge pressing, in particular to an edge pressing device. Background Art

[0002] Ton bags are a kind of flexible transport packaging container. They are moisture-proof, dust-proof, radiation-resistant, firm and safe, and have sufficient structural strength. As bulk bags are easy to load and unload, and carry, the loading and unloading efficiency has been significantly improved, and they have developed rapidly in recent years. Container bags are generally made of polyester fibers such as polypropylene and polyethylene. In the production process of existing ton bags, a flattening structure is required to cooperate with a sewing machine to press and sew the ton bags. In the first flattening and sewing process of ton bags, manual operation is mostly required to avoid flattening and sewing position errors.

[0003] The publication number is CN216330446U, which is an automatic edge pressing device for ton bag production. It straightens and presses the edge of the ton bag by setting screws and pressing plates. At the same time, it sets a straight slide rail. When the slider assembly slides on the surface of the slide rail, it can drive the edge pressing plate. The edge pressing plate drives the ton bag to perform straight edge pressing at the edge pressing end of the edge pressing assembly, which improves the edge pressing quality and efficiency. However, its main function is flattening, and it cannot locate and confirm the edge pressing position of the first edge of the ton bag. Utility Model Content

The working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail, and they are all controlled by remote control switches.

[0037] How it works

[0038] When the edge pressing device is needed, the opening of the ton bag is placed between the outer peripheries of the four slides 7, and then pulled, and the driving motor 12 is started at the same time, driving the active bevel gear 21 to rotate, so that the transmission bevel gear 22 rotates, so that the displacement screw 5 rotates, and through the limiting design of the square plate 4 and the limiting square sleeve 3, the square plate 4 can be further moved synchronously, and the Mitsubishi long angle 6 and the slide 7 can support the side of the ton bag;

[0039] At the same time, by controlling the switch and the controller, the four linear motors 10 are started to drive the positioning cone plate 2, so that the pointed cone of the positioning cone plate 2 performs an internal support design on the ton bag, so that the outer periphery of the ton bag is kept in a tensioned state;

[0040] The drive motor 12 and the linear motor 10 are adjusted synchronously to allow the slide 7 to pass through the two clamps 8, so that the side 13 of the ton bag is on the outside of the clamp 8, and then the drive motor 12 is started to drive the slide 7 to retract inward and separate from the two clamps 8, so that only the side 13 of the ton bag remains at the outside of the sewing equipment (that is, edge pressing can be achieved), and then the sewing equipment is operated to sew the side 13 of the ton bag.
