Description

Technical Field

[0001] This utility model relates to the field of air-jet loom technology, and in particular to an anti-wrinkle device for air-jet looms. Background Technology

[0002] Air-jet looms are shuttleless looms that use jet airflow to guide the weft yarn through the shed. The working principle is to use air as the weft-guiding medium; the compressed airflow generated by the jet creates frictional traction on the weft yarn, pulling it through the shed. The jet of air achieves the purpose of weft insertion.

[0003] In the prior art, such as the air-jet loom disclosed in patent publication number CN113802247B for reducing the length of waste selvage yarn in an air-jet loom, there is an air-jet loom body. The air-jet loom body has a transfer roller rotatably connected to its surface, a reed body fixedly connected to its surface, an observation mechanism fixedly provided on one side of the air-jet loom body, and a stretching mechanism fixedly provided on its surface. The stretching mechanism and the reed body are movably connected. A finishing mechanism is fixedly provided inside the observation mechanism. Compared with the prior art, by turning the second handle, the second handle drives the double-headed screw to rotate. While the double-headed screw rotates, the guide block moves vertically. While the guide block moves, the pressure plate and the cutter body move vertically. The two sets of pressure plates clamp and press the weft yarn inside the weft probe body. The weft yarn clamped by the two sets of pressure plates is cut by the cutter body, thereby completing the weft cutting work and effectively improving the weaving efficiency of the fabric.

[0004] However, existing air-jet looms use rollers to wind up the weft yarn after weaving. During this process, the weft yarn is prone to wrinkling, so an anti-wrinkle device is needed to solve this problem. However, existing anti-wrinkle devices have limited anti-wrinkle effect and are subject to limitations in use, so improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide an anti-wrinkle device for air-jet looms, which has excellent anti-wrinkle effect.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an anti-wrinkle device for an air-jet loom, comprising a first telescopic component, a moving component, and a cylinder, wherein a second telescopic component is slidably connected to the top of the moving component, and a support roller is rotatably connected to the inner side of both the first and second telescopic components, a push rod is provided at the output end of the cylinder, a roller frame is fixedly connected to the bottom end of the push rod, a tension roller is rotatably connected to the inside of the roller frame, a connecting plate is fixedly connected to the outer side of the second telescopic component, a motor is fixedly installed on the outer side of the connecting plate, a cleaning roller is rotatably connected to the inside of the connecting plate, the cleaning roller is fixedly connected to the output end of the motor, and a brush is fixedly connected to the outside of the cleaning roller.

The support roller is rotatably connected to the inner side of the first and second telescopic components. During the winding process, the weft yarn is supported by the two support rollers. The cylinder is activated, causing it to extend and retract via a push rod, extending the tension roller into the gap between the two support rollers. The tension roller contacts the weft yarn, causing it to form a V-shape. At this time, tension is generated in the weft yarn body. Simultaneously, the first and second telescopic components drive the two support rollers to extend and retract. When the two support rollers are raised, the tension of the weft yarn will increase again. By increasing the tension of the weft yarn, wrinkles can be largely prevented during winding. During winding, the weft yarn will contact the brush on the outside of the cleaning roller. The motor is activated, causing it to drive the cleaning roller to contact the brush, thereby cleaning and removing impurities from the weft yarn, resulting in a clean weft yarn after winding.

[0011] By adopting the above technical solution, the limiting pin is inserted into the lower column and the through hole, which can fix the inner rod inside the lower column.

[0012] A further feature of this invention is that the number of through holes is several, and the spacing between any two of the several through holes is equal.

[0013] By adopting the above technical solution, multiple through holes are arranged side by side on the inner side of the inner rod, so that the upper column can be fixed by inserting the limiting pin into any one of the through holes.

[0014] A further feature of this invention is that: both sides of the inner wall of the lower column are provided with sliding tracks, and the upper column is slidably connected inside the sliding tracks.

[0015] By adopting the above technical solution, when the inner rod extends or retracts inside the lower column, the inner rod will be limited inside the slide rail, and the inner rod will be slidably connected inside the slide rail, preventing the inner rod from swaying or shaking during the extension or retraction process.

[0016] A further feature of this invention is that a handle is fixedly connected to one end of the limiting pin, and an anti-slip sleeve is fixedly connected to the outside of the handle.

[0017] By adopting the above technical solution, it is relatively convenient to insert the limiting pin into the through hole and the interior of the lower column by holding the handle.

[0018] A further feature of this invention is that the moving component includes a slide rail, and a slider is slidably connected inside the slide rail, with the second telescopic component fixed to the top of the slider.

[0019] By adopting the above technical solution, the slider is slidably connected inside the slide rail, and the second telescopic component is fixed on the top of the slider, so that the second telescopic component can move inside the slide rail, and the distance between the second telescopic component and the first telescopic component can be adjusted.

[0020] A further feature of this invention is that both sides of the slider are fixedly connected to screws, and the external threads of the screws are connected to nuts.

[0021] By adopting the above technical solution, the nut is twisted to make it move outside the screw, and the nut is locked on the outer wall of the slide rail, thus fixing the slider and the second telescopic component.

[0022] A further feature of this invention is that a support plate is fixedly connected to the bottom of the first telescopic component, and first mounting blocks are fixedly connected to both sides of the support plate, with first bolts threaded into the internal threads of the first mounting blocks.

[0023] By adopting the above technical solution, the first telescopic component is supported by a support plate, and the first bolt is threaded to the inside of the first mounting block, so that the first bolt extends into the inside of the base surface, thereby fixing the first telescopic component to the base surface. This not only provides a good fixing effect but also makes disassembly convenient.

[0024] A further feature of this invention is that a second mounting block is fixedly connected to both sides of the cylinder, and a second bolt is threaded into the interior of the second mounting block.

[0025] By adopting the above technical solution, the second bolt is threaded into the interior of the second mounting block, so that the second bolt extends into the interior of the ceiling, thereby fixing the cylinder to the ceiling.

When the two support rollers are raised, the tension of the weft yarn will increase again. By increasing the tension of the weft yarn, the weft yarn can be greatly prevented from wrinkling during the winding process. During the winding process, the weft yarn will come into contact with the brush on the outside of the cleaning roller. The motor is started, causing the motor to drive the cleaning roller to contact the brush, thereby achieving the purpose of cleaning and removing impurities from the weft yarn, making the weft yarn clean after winding.
