Description

Technical Field

[0001] The invention belongs to the technical field of textile equipment, and in particular relates to a warp stop frame with an improved structure. Background Art

[0002] With the development of science and technology, the production efficiency and product qualification rate of looms are getting higher and higher. In the weaving process, many warps are needed to weave at the same time. If one of the warps is broken, the quality of the fabric will be unqualified. Therefore, the warp stop frame that detects whether the warp is broken is one of the important and indispensable parts of the loom. It can effectively detect the condition of each warp and stop the loom in time. At present, the warp stop frame mainly adopts a structure in which a warp dropper is set on the warp bar, and the warp passes through the warp dropper so that the warp dropper is suspended on the warp bar. At this time, the chip on the warp bar and the iron package are in a non-conductive state due to the isolation of the insulating clip. When a warp yarn is disconnected, the warp dropper, which was originally in a suspended state, will fall onto the warp bar due to the loss of the warp yarn bundle, so that the chip in the insulated separation state is connected to the iron package, and the signal is fed back to the electrical control box of the loom through the warp bar junction box on the warp stop frame, so that the loom stops, and then the broken warp yarn is found and connected by the stopper, so as to achieve the purpose of detection and avoid the loom from weaving defective fabrics. However, there are many types and models of looms, and in order to reduce the frequency of changing the warp beam and improve the efficiency of the loom, most looms enlarge the size of the warp beam and raise the yarn outlet surface. However, the cloth opening cannot be raised at the same time because it needs to adapt to the car-blocking operation, so that the yarn outlet and the cloth opening form an inclined angle. Therefore, during installation, the warp stop frame is usually rotated by a certain angle according to the state of the warp so that the warp and the warp stop frame can be parallel, thereby ensuring that the warp can pass through the warp stop frame smoothly. However, the warp stop bars on the warp stop frame after the above-mentioned rotation and tilt will also be in an inclined state, and the warp stop plates are connected to the warp and are still perpendicular to the horizontal base surface under the influence of gravity. This results in the warp stop bars and the warp stop plates being unable to be parallel to each other and causing close friction. Since the warp stop plates themselves are very thin metal sheets, the warp stop plates and the warp stop bars will cause accelerated wear after a long period of close friction, which greatly shortens the service life of the warp stop plates and the warp stop bars.

[0003] In the existing technologies, such as the "a novel warp stop frame device for textile equipment" provided by China Invention Patent Application Publication No. CN107858783A, and the "a warp stop frame" provided by China Invention Patent Authorization Publication No. CN103061010B, although both can realize the function of detecting the state of the warp threads, both adopt a structure in which the warp stop pieces are perpendicular to the horizontal base surface and the warp stop frame body. In order to make the plane where the warp stop frame is located parallel to the plane where the warp threads are located, it is necessary to rotate a certain angle during installation. After the rotation, the warp stop bars on the warp stop frame will also tilt and cause interference and close friction with the warp stop pieces that rely on gravity to be perpendicular to the horizontal base surface. Similarly, both cannot solve the problems existing in the above-mentioned warp stop frames.

[0004] In view of the above situation, it is necessary to design a warp stop frame with an improved structure that can keep the dropper and the warp bar parallel to each other when the warp stop frame is rotated and installed, and avoid the dropper and the warp bar from rubbing against each other. To this end, the applicant has made a useful design, and the technical solution to be introduced below is produced in this context. Summary of the invention
