Description

Technical Field

[0001] The invention relates to the technical field of weaving equipment, and in particular to a shuttle guide rail structure for a weaving machine. Background Art

[0002] Carbon fiber composite materials are being widely used in advanced fields such as aerospace, wind power generation, and shipbuilding due to their excellent performance. Therefore, the research and development of high-performance carbon fiber textile equipment is particularly important. During the use of existing textile equipment, the shuttle wheel supporting the shuttle body will crush the warp yarns. At the same time, the warp yarns will be scraped and crushed again when passing through the shuttle pusher and the shuttle rear pusher, which can easily cause the warp yarns to be scratched, broken, or entangled with the shuttle pusher.

[0003] To solve the above problems, Chinese patent publication number CN102634915B discloses a circular guide shuttle roller device, which has guide wheels installed on the track surfaces of upper and lower door rings, and a guide shuttle column with a gear between the upper and lower door rings. The shuttle has guide bars on the upper and lower sides, which can move in the V-shaped groove of the guide wheel, and the back of the shuttle has an arc-shaped rack that can mesh with the gear on the guide shuttle column. When working, the guide shuttle motor drives the synchronous pulley installed at the lower end of the guide shuttle column through a synchronous toothed belt to rotate the guide shuttle column, and the meshing action of the gear on the guide shuttle column and the arc-shaped rack on the back of the shuttle drives the shuttle to move forward on the guide wheel; since the power of the shuttle is provided by the guide shuttle column, the whole machine does not need a shuttle pusher assembly, and also avoids the scratching of the warp yarn and the shuttle pusher, so that the equipment has lower requirements on the strength and wear resistance of the warp yarn, which is suitable for weaving various high and low strength yarns or yarns with poor wear resistance, thereby ensuring product quality.

[0004] During the actual use of the above-mentioned patent, the guide shuttle motor drives the synchronous pulley installed at the lower end of the guide shuttle column through the synchronous toothed belt, so that the guide shuttle column rotates, and the meshing action of the gear on the guide shuttle column and the arc-shaped rack on the back of the shuttle drives the shuttle to move forward on the guide wheel, that is, the patent mainly realizes the movement of the shuttle through mechanical transmission; but the mechanical transmission structure to realize the movement of the shuttle requires more parts. On the one hand, the installation is cumbersome and the investment cost is high, and on the other hand, it takes up more space. Summary of the Invention

[0005] The present invention aims to provide a shuttle guide rail structure for a weaving machine, so as to solve the problem that the existing shuttle guide roller device adopts a mechanical transmission method to make the shuttle movement costly.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a shuttle guide rail structure for a weaving machine, comprising a weft yarn tube and a warp yarn arm, the warp yarn arm is provided with a yarn guide hole for leading out the yarn on the weft yarn tube, and also comprises a guide rail and a shuttle body; the warp yarn arm is fixedly connected to the shuttle body; fixed seats are provided on both sides of the shuttle body, a weft yarn shaft is provided between the two fixed seats, and the weft yarn tube is sleeved on the outside of the weft yarn shaft; ball bearings are provided on both sides of the weft yarn tube, the inner wall of the ball bearing is fixedly connected to the weft yarn shaft, and the outer wall of the ball bearing is fixedly connected to the inner wall of the weft yarn tube; guide wheel groups are provided on both sides of the shuttle body, the guide wheel group comprises a guide shaft rotatably connected to the shuttle body and a guide wheel moving in the guide rail, the guide wheel is fixedly connected to the guide shaft, and also comprises a power unit for driving a guide shaft to rotate, and the power unit is arranged on the shuttle body.

[0007] The principles and advantages of this solution are: this solution drives a guide shaft to rotate through the power unit, and then drives the guide wheel on the guide shaft to move along the path of the guide rail, so that the other guide wheels also move in the guide rail, thereby improving the stability of the shuttle body movement; during the movement of the shuttle body, the yarn on the weft yarn tube is output under the guidance of the yarn guide hole; compared with the prior art, the power for the movement of the shuttle body in the present invention is driven by the power unit on the shuttle body, and there is no need for a push shuttle assembly and a mechanical transmission structure, which effectively avoids the scratching of the yarn and the push shuttle, and reduces the equipment's requirements for yarn strength and wear resistance, and is suitable for weaving various high- and low-strength silks or yarns with poor wear resistance, thereby ensuring product quality; and, the power unit for driving the shuttle body movement in this solution is arranged on the shuttle body, without taking up extra space or requiring cumbersome installation procedures, while also reducing the use of components and effectively reducing investment costs.

[0008] Furthermore, both ends of the weft yarn shaft are provided with a first threaded section, and the weft yarn tube is located between the two first threaded sections; and an adjusting nut is threadedly connected to the first threaded section.

[0009] Through the above arrangement, the adjusting nut and the weft yarn tube are offset against each other, which can adjust the rotation speed of the weft yarn tube on the one hand, and prevent the weft yarn tube from moving along the axial direction of the weft yarn axis on the other hand, thereby ensuring that the yarn on the weft yarn tube is effectively output and the woven weft yarn will not be loose.

[0010] Furthermore, first springs are sleeved on both ends of the weft shaft, and both ends of the first spring are respectively against the adjusting nut and the fixing seat.

[0011] With the above arrangement, the first spring can buffer the axial movement of the weft tube via the adjusting nut, thereby further preventing the weft shaft from moving along the axial direction of the weft tube.

[0012] Furthermore, the power unit includes a motor fixed on the shuttle body and a first transmission wheel fixed on a guide shaft, a second transmission wheel fixed on the output shaft of the motor, and a transmission belt is sleeved between the second transmission wheel and the first transmission wheel.

[0013] Through the above arrangement, the motor is started, and the output shaft of the motor drives the second transmission wheel to rotate, the second transmission wheel drives the first transmission wheel to rotate through the transmission belt, and the first transmission wheel drives a guide shaft to rotate, thereby driving the guide wheel on the guide shaft to move along the path of the guide rail, that is, driving the shuttle body to move synchronously.

[0014] Furthermore, there are two guide shafts, which are respectively arranged on both sides of a single side of the shuttle body.

[0015] With the above arrangement, while the shuttle body is moving, the other running wheels also move in the guide rails, thereby improving the stability of the shuttle body's movement.

[0016] Furthermore, the guide rail includes two fixed circular rings, and the bottom of one circular ring and the top of the other circular ring are both provided with guide grooves, and the two guide grooves form a guide rail for the movement of the guide wheel.

[0017] With the above arrangement, the shuttle body moves in a circular motion along the path of the guide rail.

[0018] Furthermore, a number of rotating shafts are circumferentially equidistantly connected between the two circular rings, a number of chambers are circumferentially equidistantly provided inside the circular rings, the rotating shafts extend into the chambers, a circular shaft is rotatably connected inside the chambers, a belt is provided between the rotating shafts and the circular shafts, an elliptical disk is fixedly connected to the circular shafts; piston cylinders are provided on both sides of the circular shafts, the piston cylinders are fixedly connected to the inner wall of the chambers, a piston block is slidably connected to the piston cylinders and abuts against the elliptical disk, a second spring is provided between the piston block and the piston cylinder; the piston cylinders are connected to an air inlet pipe passing through the circular rings and an air outlet pipe communicating with the guide groove; and it also includes a linkage part that drives the rotating shaft to rotate as the shuttle body moves.

[0019] Through the above arrangement, during the movement of the shuttle body, the shuttle body drives the rotating shaft to rotate through the linkage part, the rotating shaft drives the circular shaft to rotate through the belt, and the circular shaft drives the elliptical disk to rotate, so that the long axis end of the elliptical disk squeezes the piston block and the second spring is compressed; the piston block squeezes the gas in the piston cylinder and acts on the guide groove through the outlet pipe, which can cool the guide groove and the guide wheel, thereby reducing the damage caused by high-temperature friction between the two and extending the service life of both; the circular shaft continues to rotate, so that the long axis end of the elliptical disk no longer contacts the piston block, and the piston block is reset under the action of the second spring. At this time, the short axis end of the elliptical disk contacts the piston block; during the reset of the piston block, negative pressure is generated in the piston cylinder, thereby sucking outside air into the piston cylinder for the next cooling treatment.

[0020] Furthermore, the air outlet pipe includes a vertical section, a dispersion section and several air outlet sections. The vertical section is connected to the piston cylinder. The dispersion section is connected to the vertical section and the air outlet section respectively. The air outlet section is connected to the guide groove.

[0021] With the above arrangement, the piston block squeezes the gas in the piston cylinder to act on the guide groove through the vertical section, the dispersion section and the gas outlet section, which can cool the guide groove and the guide wheel.

[0022] Furthermore, the width of the air outlet section gradually decreases from the dispersion section toward the guide groove.

[0023] Through the above arrangement, due to the change in width, the gas ejected from the gas outlet section has a certain impact force, and the gas can be dispersed when acting on the guide wheel, thereby expanding the cooling range and achieving a better cooling effect.

[0024] Furthermore, the linkage part includes an arc-shaped rack and several gears for engaging with the arc-shaped rack. The arc-shaped rack is fixed to the shuttle body, and the gears are fixed to the rotating shaft. The arc-shaped rack can engage with two adjacent gears at the same time.

[0025] Through the above arrangement, during the movement of the shuttle body, the shuttle body will drive the arc rack to move synchronously, so that the arc rack engages with the gear to drive the gear to rotate, the gear drives the shaft to rotate, and the shaft drives the circular shaft to rotate through the belt.

[0034] The two rings 31 are rotatably connected with a plurality of rotating shafts 32 at equal intervals in the circumference. A plurality of chambers 33 are rotatably provided in the ring 31 at equal intervals. The rotating shaft 32 extends into the chamber 33. A circular shaft 331 is rotatably connected in the chamber 33. A belt 332 is sleeved between the rotating shaft 32 and the circular shaft 331. An elliptical disk 333 is fixedly connected to the circular shaft 331. A piston cylinder 334 is provided on both sides of the circular shaft 331. The piston cylinder 334 is fixedly connected to the inner wall of the chamber 33 and is located above the belt 332. A piston block 3341 is slidably connected to the piston cylinder 334 and abuts against the elliptical disk 333. A second spring 3342 is fixedly connected between the piston block 3341 and the piston cylinder 334. The piston cylinder 334 is connected to an air inlet pipe 3343 passing through the ring 31 and an air outlet pipe 3344 communicating with the side wall of the guide groove 311. The air inlet pipe 3343 is equipped with a piston rod 3341 for unidirectionally passing through the piston cylinder 334. The air inlet pipe 3343 enters the first one-way valve of the piston cylinder 334; the air outlet pipe 3344 includes a vertical section 33441, a dispersion section 33442 and several air outlet sections 33443. The vertical section 33441 is connected to the piston cylinder 334, and the dispersion section 33442 is respectively connected to the vertical section 33441 and the air outlet section 33443. The air outlet section 33443 is connected to the guide groove 311. The vertical section 33441 is installed with a second one-way valve for the fluid to enter the air outlet section 33443 from the vertical section 33441 in one direction; it also includes a linkage part that drives the rotating shaft 32 to rotate as the shuttle body 40 moves. The linkage part includes an arcuate rack 45 and several gears 321 for engaging with the arcuate rack 45. The arcuate rack 45 is fixedly connected to the shuttle body 40, and the gear 321 is fixedly connected to the rotating shaft 32; the arcuate rack 45 can engage with two adjacent gears 321 at the same time.

[0035] The specific implementation process is as follows:

[0036] During use, the motor 44 is started, and the output shaft of the motor 44 drives the second transmission wheel 441 to rotate. The second transmission wheel 441 drives the first transmission wheel 432 to rotate via the transmission belt. The first transmission wheel 432 drives a guide shaft 43 to rotate, which in turn drives the guide wheel 431 on the guide shaft 43 to perform circular motion along the path of the guide rail 30, that is, drives the shuttle body 40 to perform circular motion, causing the other guide wheels 431 to also move within the guide rail 30, thereby improving the stability of the shuttle body 40. During the movement of the shuttle body 40, the yarn on the weft bobbin 10 is output under the guidance of the yarn guide hole 21.

[0037] The motor 44 is installed on the shuttle body 40, and the effect is: the power for the movement of the shuttle body 40 in this solution is driven by the motor 44 on the shuttle body 40, and there is no need for a push shuttle assembly and a mechanical transmission structure, which effectively avoids the scratching of the yarn and the push shuttle, and reduces the equipment's requirements for the strength and wear resistance of the yarn. It is suitable for weaving various high- and low-strength silks or yarns with poor wear resistance, ensuring product quality; and, in this solution, the motor 44 used to drive the movement of the shuttle body 40 is set on the shuttle body, without taking up extra space or requiring cumbersome installation procedures, and at the same time can reduce the use of parts, thereby effectively reducing investment costs. When the shuttle body 40 makes a circular motion along the path of the guide rail 30, the shuttle body 40 drives the arc-shaped rack 45 to move synchronously, so that the arc-shaped rack 45 meshes with the gear 321 to drive the gear 321 to rotate, and the gear 321 drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the circular shaft 331 to rotate through the belt 332, and the circular shaft 331 drives the elliptical disk 333 to rotate, so that the long axis end of the elliptical disk 333 squeezes the piston block 3341, and the second spring 3342 is compressed; the piston block 3341 squeezes the gas in the piston cylinder 334 through the vertical section 33441, the dispersion section 33442, and the gas outlet section 33443. The second spring 3342 acts on the guide groove 311, thereby cooling the guide groove 311 and the guide wheel 431, thereby reducing damage caused by high-temperature friction between the two and extending their service life. The circular shaft 331 continues to rotate, so that the long axis end of the elliptical disk 333 no longer contacts the piston block 3341. The piston block 3341 is reset under the action of the second spring 3342. At this time, the short axis end of the elliptical disk 333 contacts the piston block 3341. During the reset of the piston block 3341, negative pressure is generated in the piston cylinder 334, thereby sucking air from the outside into the piston cylinder 334 for the next cooling process. Since the arc-shaped rack 45 can mesh with two gears 321 at the same time, the meshing time of the arc-shaped rack 45 and a single gear 321 is long enough to allow the piston block 3341 to complete the reciprocating work in the piston cylinder 334.

[0038] In this embodiment, the width of the air outlet section 33443 gradually decreases from the dispersion section 33442 toward the guide groove 311; due to the change in width, the gas ejected from the air outlet section 33443 has a certain impact force, and the gas can be dispersed when acting on the guide wheel 431, thereby expanding the cooling range and achieving a better cooling effect.

[0039] In this embodiment, both ends of the weft yarn shaft 42 are slidably connected with a partition, which is located between the ball bearing and the adjusting nut 421; replacing the adjusting nut 421 with the partition in contact with the ball bearing can increase the contact area and thus increase the friction, that is, strengthen the limiting effect of the weft yarn tube 10. On the one hand, it can more stably adjust the rotation speed of the weft yarn tube 10, and on the other hand, it can better prevent the weft yarn tube 10 from moving along the axial direction of the weft yarn shaft 42.

[0040] The above is only an embodiment of the present invention, and the common knowledge such as the specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
