Description

Technical Field

[0001] The utility model relates to the technical field of double-rapier looms, in particular to an air cushion guide rail rapier press for double-rapier looms. Background Art

[0002] The double rapier loom is a special type of loom that uses a double rapier structure. This structure can make the loom more stable and improve the quality of the fabric and production efficiency. The air cushion guide is a device used to reduce the friction and vibration of the machine during operation, which can improve the running stability of the loom and the quality of the weaving. The sword press is a device used to control the upper and lower swords of the loom. It plays an important role in the double rapier loom and can ensure the tightness and overall quality of the fabric.

[0003] In the process of the sword presser keeping the rapier stable, as the sword presser mechanism or the rapier moves, friction will be generated between the two. The large friction will cause the rapier to wear and affect the service life of the rapier. Utility Model Content

[0004] The utility model aims to provide an air cushion guide rail sword press for a double rapier loom, which has the advantages of reducing friction and wear between the rapier and the air cushion guide rail while applying pressure to the rapier to maintain the stability of the rapier, thereby solving the problem that the friction between the rapier and the air cushion guide rail is large, resulting in serious wear of the rapier.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an air cushion guide rail sword press for a double rapier loom, comprising an air cushion slide rail body and a slider, a fixing frame is welded at the bottom of the air cushion slide rail body, the slider and the air cushion slide rail body are slidably connected, two springs are symmetrically installed on the top of the slider, a retaining frame is installed on the top of the two springs, three pulleys are rotatably installed inside the retaining frame, a fixing block 2 is respectively welded at the front and rear ends of the retaining frame, a fixing block 1 is respectively installed at the front and rear ends of the slider, movable rods are respectively installed at the bottom of the two fixing blocks 2, a connecting pipe is embedded in the side of the air cushion slide rail body, and support frames are respectively installed on both sides of the air cushion slide rail body above the connecting pipe.

[0006] When using the double rapier loom air cushion guide sword press in the technical solution, the fixing frame is fixed to the reserved bearing structure of the double rapier loom through the fixing holes of the fixing frame using bolts and other tools, so that the three pulleys on the inner side of the retaining frame are in contact with the rapier, and the connecting pipe is connected to the pipeline for conveying gas through a flange. The gas enters the interior of the air cushion slide rail body from the connecting pipe. The air cushion slide rail body pushes the slider to move back and forth laterally through the gas, and the slider drives the retaining frame to move laterally through the spring. The pulley on the inner side of the retaining frame moves laterally to apply pressure to the rapier to keep the rapier stable. The spring under the retaining frame is compressed and rebounded during the movement to provide buffering, thereby reducing the friction between the pulley and the rapier.

[0007] Preferably, the bottom of the fixing frame is provided with fixing holes in a rectangular array. The fixing frame is fixed to the bearing structure reserved for the double rapier loom by using tools such as bolts through the fixing holes of the fixing frame.

[0008] Preferably, a flange is installed at one end of the connecting pipe away from the air cushion slide rail body. The connecting pipe is connected to a pipeline for conveying gas through the flange.

[0009] Preferably, the two fixing blocks are respectively provided with movable holes, the bottoms of the two movable rods respectively pass through the two movable holes, and the bottoms of the two movable rods are respectively installed with stoppers. The two movable rods limit the holding frame, and when the holding frame is raised or lowered, the two movable rods move in the two movable holes to prevent the holding frame from shaking, and the two stoppers prevent the two movable rods from sliding out of the two movable holes.

[0010] Preferably, baffles are respectively installed on opposite sides of the two support frames. The two baffles limit the range of lateral movement of the slider on the air cushion slide rail body.

[0011] Preferably, the three pulleys extend into the top of the retaining frame. When the pulleys contact the rapier, the retaining frame will not interfere with the rapier.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model provides a spring and a pulley, wherein the slide block drives the retaining frame to move laterally through the spring, and the pulley inside the retaining frame moves laterally to exert pressure on the rapier to maintain the stability of the rapier, and the spring below the retaining frame is compressed and rebounds during the movement to provide buffering, thereby reducing the friction between the pulley and the rapier, thereby achieving the effect of exerting pressure on the rapier to maintain the stability of the rapier and reducing the friction between the rapier and the rapier, thereby reducing the wear.
