Description

Technical Field

[0001] The utility model belongs to the technical field of plastic woven bag production, and in particular relates to a wire releasing mechanism of a plastic woven bag weaving machine. Background Art

[0002] Plastic woven bags are mainly made of polypropylene bags and polyethylene bags; they are divided into bottom-sewn bags and side-sewn bottom-sewn bags according to the sewing method. Currently, they are widely used as a packaging material for fertilizers, chemical products and other items. The main production process is to use plastic raw materials to extrude films, cut, and unidirectionally stretch them into flat wires, and then weave them through warp and weft to obtain products, which are generally called woven bags.

[0003] Plastic flat wire, referred to as flat wire in the plastic weaving industry, is also called cutting fiber. It is the basic material for plastic woven bags for producing plastic woven fabrics. The flat wire is made of a specific variety of polypropylene and polyethylene resin through melt extrusion into a film, and then cut into strips longitudinally. The strips are heated, stretched, oriented and shaped at the same time, and finally wound into flat wire spindles for weaving woven fabrics.

[0004] In the Chinese patent with publication number CN 218261231 U, a wire roller is sleeved on the outer wall of the plug column, the wire is passed through the through hole and contacts the rotating shaft, and the other end is connected to the machine. The rotating shaft can contact the bottom plate to reduce friction when the machine drives the wire to release the wire, and the second threaded rod can be moved at the second threaded hole by rotating the turntable, so that the concave plate slides inside the second slide groove. The compression degree of the wire can be adjusted by the rotating shaft, so that the tightness can be adjusted to prevent the wire from being too loose and falling and rubbing against the inner wall of the through hole, resulting in the wire breaking;

[0005] However, the device has the following problems during use:

[0006] In order to ensure that the wire roller can rotate around the plug post normally, the slot on the inside of the wire roller is larger than the outer diameter of the plug post. This causes the wire roller to shake compared to the plug post during the wire pay-off process. During high-speed wire pay-off, a loud noise will be generated between the wire roller and the plug post due to the shaking, and the wire roller is prone to falling off. Utility Model Content

[0007] The utility model aims to provide a wire releasing mechanism for a plastic woven bag weaving machine to solve the problems raised by the above-mentioned background technology.

[0008] To achieve the above purpose, the utility model provides the following technical solution, including a wire roller, both ends of which are clamped on two fixing frames respectively, the fixing frames are provided with a clamping mechanism for fixing and releasing the wire roller, and the fixing frames are rotatably mounted on the bracket;

[0009] The clamping mechanism comprises two sector plates, an opening is provided between the two sector plates, and the opening allows the wire roller to pass through;

[0010] Two pressure plates are inserted in the two sector plates, and the two pressure plates are respectively located on both sides of the line roller. The pressure plates are slidably connected to the through holes in the sector plates, and the pressure plates are connected to a pressure mechanism for driving them to move closer to or away from each other.

[0011] Preferably, a guide rail is provided on the fixed frame, the guide rail is arranged at the middle position of the opening, a slide groove is provided at the position of the line roller corresponding to the guide rail, and a blocking block with a height higher than the depth of the slide groove is fixedly installed at the end of the guide rail.
