Description

Technical Field

[0001] The invention belongs to the technical field of textiles, and in particular relates to a low-water-pressure water-jet weaving device for high-modulus polyester fibers. Background Art

[0002] In the textile field, high modulus polyester fiber occupies an important position in the production of industrial textiles such as mooring ropes and high-performance fabrics due to its high strength, high modulus and low elongation. As the market's requirements for the quality, performance and production efficiency of high modulus polyester fiber fabrics continue to rise, the matching weaving technology is also facing new challenges and opportunities.

[0003] The water supply mechanism of the traditional water jet weaving device is difficult to balance energy saving and efficient use of water resources while ensuring stable water pressure. Excessive water pressure not only leads to waste of water resources, but may also cause excessive impact on high modulus polyester fibers, resulting in fiber damage, affecting the final strength, flatness and other quality indicators of the fabric, and reducing the market competitiveness of the product. Conventional weaving devices have poor flexibility and precision in adjusting the weft insertion angle. Due to its special physical properties, high modulus polyester fibers have extremely stringent requirements on the angle at which the weft yarn enters the shed during the weaving process. If the weft insertion angle deviates, the weft yarn is difficult to accurately position, and weaving defects are likely to occur, greatly reducing the product's qualified rate. Existing adjustment mechanisms are often complex in structure and slow in adjustment response speed, making it difficult to adapt to the demand for real-time angle adjustment during high-speed weaving. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a low-water-pressure water-jet weaving device for high-modulus polyester fibers.

[0005] The technical solution adopted to solve the above technical problems is: a low-pressure water jet weaving device for high-modulus polyester fiber, comprising a main frame, a control console installed at a front end position on one side of the main frame, a warp let-off assembly installed at a rear end position on one side of the main frame, an opening assembly installed at the top of the main frame, and a beating-up assembly cooperating with the opening assembly installed inside the main frame; A low-pressure water supply mechanism for water jet weft insertion is provided inside the main frame. A docking block is fixedly connected to the main frame near the beat-up assembly. A docking pipe corresponding to the warp let-off assembly is installed on the top of the docking block. The interior of the docking block is provided with a plurality of water pressure regulating mechanisms for adjusting the water pressure of the water spraying, a plurality of connecting pipes are installed between the interior of the docking block and the docking pipe, and the other ends of the plurality of connecting pipes are provided with angle adjustment mechanisms for subsequent adjustment of the water spraying angle, and the interior of the main frame is provided with a winding assembly.

[0006] Furthermore, the low-pressure water supply mechanism includes a water tank installed inside the main frame, a low-pressure water pump is installed inside the main frame near the water tank, the water outlet of the low-pressure water pump is connected to the water inlet of the buffer pressure stabilizing tank, the water outlet of the buffer pressure stabilizing tank is fixedly connected to a water supply pipe, a water distributor is installed at the other end of the water supply pipe, and multiple water distribution pipes are installed on one side of the water distributor.

[0007] Through the above technical solution, when water supply is needed, the low-pressure water pump installed inside the main frame and close to the water tank is started, and the water in the water tank is pumped out through its pumping function. At this time, the water flow obtains initial power under the action of the low-pressure water pump and enters the transportation link. The water flow follows this connection path into the buffer pressure-stabilizing tank. The buffer pressure-stabilizing tank can effectively alleviate the pressure fluctuations generated by the water flow during the transportation process, and plays a key role in stabilizing the water pressure. The water flow after pressure stabilization by the buffer pressure-stabilizing tank is guided to the water distributor installed at the other end, and the concentrated water flow transported through the water supply pipe is distributed to multiple water distribution pipes installed on its side. Finally, each water distribution pipe transports the low-pressure water flow to different water use terminals, completing the entire low-pressure water supply process.

[0008] Furthermore, a pressure-stabilizing airbag is provided inside the buffer pressure-stabilizing tank. The pressure-stabilizing airbag is fixedly connected to the inner wall of the buffer pressure-stabilizing tank via an annular clamp, and an elastic sealing gasket is provided on the inner side of the clamp.

[0009] Through the above technical solution, the pressure-stabilizing airbag arranged inside the buffer pressure-stabilizing tank can respond to changes in water flow pressure more accurately through its own elastic contraction and expansion, further enhance the buffering effect on water pressure fluctuations, and significantly improve the water pressure stability performance. The pressure-stabilizing airbag is fixedly connected to the inner wall of the buffer pressure-stabilizing tank by an annular clamp. This connection method not only ensures the stability of the pressure-stabilizing airbag's position in the tank, prevents it from displacement or shaking under the impact of water flow, and ensures the stable performance of the pressure-stabilizing function.

[0010] Furthermore, the water pressure regulating mechanism includes a regulating box installed inside the docking block, an regulating motor installed inside the regulating box, an output end of the regulating motor fixedly connected to a driving gear, a fixed plate fixedly connected to the inside of the regulating box near the driving gear position, one side of the fixed plate rotatably connected to a transmission gear, the other side of the transmission gear fixedly connected to an adjusting threaded rod, a plurality of limit rods fixedly connected between the other side of the fixed plate and the regulating box, a sliding block slidably connected between the plurality of limit rods, a docking threaded tube corresponding to the adjusting threaded rod installed on one side of the sliding block, an adjusting rod fixedly connected on the other side of the sliding block, a positioning seat fixedly connected on one side of the regulating box, two sealing rings installed inside the positioning seat, and a connecting port corresponding to the adjusting rod installed inside the low water pressure water supply mechanism.

[0011] Through the above technical solution, the regulating box installed inside the docking block provides a stable installation and operation space for the entire mechanism. When the water pressure needs to be adjusted, the regulating motor inside the regulating box is started, and the driving gear fixedly connected to its output end rotates accordingly. Since a fixed plate is fixedly connected to the regulating box near the driving gear position, and the transmission gear rotatably connected on one side of the fixed plate is meshed with the driving gear, the rotation of the driving gear will drive the transmission gear to rotate synchronously, and the adjusting threaded rod fixedly connected on the other side of the transmission gear will also rotate accordingly. The multiple limit rods fixedly connected between the other side of the fixed plate and the regulating box play a limiting and guiding role for the sliding block slidably connected therebetween. The docking threaded tube corresponding to the adjusting threaded rod installed on one side of the sliding block will drive the sliding block to move along the limit rod when the adjusting threaded rod rotates, thereby causing the adjusting rod fixedly connected on the other side of the sliding block to displace. The two sealing rings installed inside the positioning seat fixedly connected on one side of the regulating box ensure the sealing of the adjusting rod during the movement of the adjusting rod, and the adjusting rod will extend into the corresponding connecting port installed inside the water distribution pipe, and the water pressure in the water distribution pipe can be adjusted by changing the depth of the extension.

[0012] Furthermore, a plurality of the limiting rods are evenly distributed and fixed in parallel between the other side of the fixed plate and the adjustment box, and a sliding sleeve that precisely matches the limiting rods is provided inside the sliding block.

[0013] Through the above technical solution, the supporting force on the sliding block can be more balanced when it moves, avoiding tilting or jamming of the sliding block due to uneven force, ensuring its smooth movement in a straight line, and providing a stable foundation for the precise displacement of the adjustment rod. The sliding sleeve inside the sliding block, which is precisely adapted to the limit rod, can greatly reduce the friction resistance between the sliding block and the limit rod, making the movement of the sliding block smoother and more flexible, and reducing energy consumption and component wear during the adjustment process.

[0014] Furthermore, the adjusting threaded rod and the docking threaded pipe are threadedly connected, and the thread parameters of the docking threaded pipe match the trapezoidal threads of the adjusting threaded rod.

[0015] Through the above technical solution, the trapezoidal thread itself has the characteristics of high transmission efficiency and strong load-bearing capacity. The parameter matching of the two can ensure the tightness of the threaded connection and reduce the gap, so that the rotational motion of the adjusting threaded rod can be accurately converted into the linear motion of the docking threaded tube, realizing the smooth and precise displacement of the sliding block and the adjusting rod.

[0016] Further, the angle adjustment mechanism includes a fixed base tube installed at one end of the docking tube, an outer wall of the fixed base tube is fixedly connected to a first driving assembly near the outer wall of one end, an output end of the first driving assembly is fixedly connected to a first adjusting gear, the other end of the fixed base tube is rotatably connected to the first movable tube, an outer wall of the first movable tube is fixedly connected to a first connecting gear ring near the first adjusting gear position, a second driving assembly is installed on the outer wall of the first movable tube near the other end position, an output end of the second driving assembly is fixedly connected to a second adjusting gear, the other end of the first movable tube is rotatably connected to the second movable tube, an outer wall of the second movable tube is fixedly connected to a second connecting gear ring near the second adjusting gear position, a third driving assembly is installed on the outer wall of the second movable tube near the other end position, the output end of the third driving assembly is fixedly connected to a third adjusting gear, the other end of the second movable tube is rotatably connected to the third movable tube, and the outer wall of the third movable tube is fixedly connected to the third connecting gear ring near the third adjusting gear position.

[0017] With the above technical solution, when the angle needs to be adjusted, the first driving component at one end of the outer wall of the fixed base tube is started, and the first adjusting gear fixedly connected to its output end rotates accordingly. Since the first movable tube rotatably connected to the other end of the fixed base tube has a first connecting gear ring fixedly connected to its outer wall near the first adjusting gear position, and the first connecting gear ring is meshed with the first adjusting gear, the rotation of the first adjusting gear will drive the first connecting gear ring to rotate, thereby causing the first movable tube to rotate relative to the fixed base tube to achieve angle adjustment in the first direction. When the angle needs to be further adjusted, the second driving component at the other end of the outer wall of the first movable tube is started, and the second adjusting gear at its output end rotates. Since the second movable tube rotatably connected to the other end of the first movable tube has its outer wall fixed near the second adjusting gear position. A second connecting gear ring is connected that is meshed with the second adjusting gear. The rotation of the second adjusting gear will drive the second connecting gear ring to rotate, so that the second movable tube rotates relative to the first movable tube to complete the angle adjustment in the second direction. The angle needs to be adjusted. The third driving assembly at the other end of the outer wall of the second movable tube is started, and the third adjusting gear at the output end rotates. Since the third movable tube connected to the other end of the second movable tube is rotatably connected, its outer wall is fixedly connected to the third connecting gear ring that is meshed with the third adjusting gear near the position of the third adjusting gear. The rotation of the third adjusting gear will drive the third connecting gear ring to rotate, so that the third movable tube rotates relative to the second movable tube to achieve angle adjustment in the third direction. Through the cooperation of these three levels of drive and transmission, the angle adjustment mechanism can flexibly adjust the overall angle to meet different usage requirements.

[0018] Furthermore, the first drive assembly, the second drive assembly and the third drive assembly are all servo motors, and their output shafts are fixedly connected to corresponding adjustment gears via flat keys.

[0019] Through the above technical solution, the rotation amplitudes of the first adjusting gear, the second adjusting gear and the third adjusting gear can be accurately controlled, thereby making the angle adjustment of the first movable tube, the second movable tube and the third movable tube more precise, meeting the fine requirements for angles in different scenarios. The output shaft and the corresponding adjusting gear are fixedly connected by a flat key. The flat key connection structure is simple and easy to assemble and disassemble. It can ensure the circumferential fixation between the output shaft and the adjusting gear, making the torque transmission more reliable, avoiding relative sliding, and ensuring that the power of the motor can be efficiently and stably transmitted to the adjusting gear.

[0020] Furthermore, deep groove ball bearings are installed at the rotating connections between the first movable tube and the second movable tube, and between the second movable tube and the third movable tube. The outer ring of the bearing has an interference fit with the tube body, and the inner ring has a clearance fit with the corresponding connecting shaft.

[0021] Through the above technical solution, the deep groove ball bearing can greatly reduce the friction resistance during the relative rotation of the movable tube, making the angle adjustment process smoother and more flexible, and reducing power loss. The outer ring of the bearing and the tube body adopt an interference fit, which can ensure that the outer ring of the bearing is tightly combined with the tube body, avoiding loosening or relative displacement of the outer ring during the rotation of the movable tube, providing a stable installation foundation for the bearing, and ensuring its normal force and operation. The clearance fit between the inner ring and the corresponding connecting shaft reserves appropriate space for the rotation of the connecting shaft, reducing the friction and wear between the inner ring and the connecting shaft, while allowing a certain amount of installation error and thermal expansion and contraction space to prevent rotation jamming due to overly tight fit.

[0022] The beneficial effects of the present invention are as follows: (1) The present invention designs a low-pressure water supply mechanism, provides initial power through a low-pressure water pump, and combines the functions of a buffer pressure-stabilizing tank and an internal pressure-stabilizing airbag. Under the premise of ensuring the stability of the water pressure required for water jet weft insertion, the water supply pressure can be greatly reduced, the consumption and waste of water resources can be reduced, and the energy consumption of equipment operation can be reduced. The stable low-pressure environment can avoid excessive impact of high water pressure on high-modulus polyester fibers, reduce fiber damage, ensure the stability and accuracy of weft yarn feeding during weaving, and improve the molding quality of fabrics. Low-pressure operation can reduce the load and wear of components such as pipes and water pumps, extend the service life of the water supply system and related equipment, reduce maintenance costs, and improve the economy and reliability of the device as a whole. (2) The present invention designs a water pressure regulating mechanism, drives the threaded rod and the threaded pipe to cooperate through the motor-driven gear transmission, realizes the precise displacement of the sliding block and the regulating rod, can flexibly adjust the water pressure according to the characteristics of different high-modulus polyester fibers and the weaving process requirements, and meet the diverse weft insertion needs. During the adjustment process, the cooperation of the limit rod and the sliding sleeve ensures the stability and accuracy of the adjustment. The invention avoids excessive fluctuations in water pressure that affect the quality of weft insertion and ensures the stability of the weaving process. The setting of the sealing ring enhances the sealing performance and prevents water leakage and waste. The efficient transmission characteristics of the trapezoidal thread reduce the energy consumption of adjustment, and overall improve the controllability of the device to water pressure, further optimize the fabric forming effect, and improve the adaptability and economy of production. (3) The invention designs an angle adjustment mechanism and adopts a three-stage drive component with gear and ring transmission to achieve multi-directional and high-precision angle adjustment. It can flexibly adjust the water spray angle according to the weft insertion requirements of high-modulus polyester fiber, ensure that the weft yarn enters the shed accurately, and improve the success rate of weft insertion. The precise control of the servo motor and the reliable transmission of the flat key connection ensure the stability and accuracy of the angle adjustment and avoid weaving defects caused by angle deviation. The application of deep groove ball bearings reduces the friction resistance when the movable tube rotates, making the adjustment process smoother and reducing power loss. The reasonable matching method of the bearings prolongs the service life of the mechanism, and overall enhances the adaptability of the device to different weaving scenarios, further ensures the forming quality of the fabric, and improves production efficiency and product qualification rate.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] like Figure 4 - Figure 9 As shown, the interior of the main frame 1 is provided with a low-pressure water supply mechanism 6 for water spraying and weft insertion, and the low-pressure water supply mechanism 6 includes a water tank 601 installed inside the main frame 1, and a low-pressure water pump 602 is installed inside the main frame 1 near the water tank 601. The water outlet of the low-pressure water pump 602 is connected to the water inlet of the buffer pressure stabilizing tank 603, and a pressure-stabilizing airbag is provided inside the buffer pressure stabilizing tank 603. The pressure-stabilizing airbag is fixedly connected to the inner wall of the buffer pressure stabilizing tank 603 through an annular clamp, and an elastic sealing gasket is provided on the inside of the clamp. The pressure-stabilizing airbag provided inside the buffer pressure stabilizing tank 603 can Contraction and expansion can more accurately respond to changes in water pressure, further enhance the buffering effect on water pressure fluctuations, and significantly improve the water pressure stability performance. The pressure-stabilizing airbag is fixedly connected to the inner wall of the buffer pressure-stabilizing tank 603 through an annular clamp. This connection method can not only ensure the stability of the pressure-stabilizing airbag in the tank, but also prevent it from being displaced or shaken under the impact of water flow, thereby ensuring the stable performance of the pressure-stabilizing function. The water outlet of the buffer pressure-stabilizing tank 603 is fixedly connected to a water supply pipe 604, and a water distributor 605 is installed at the other end of the water supply pipe 604. A plurality of water distribution pipes 606 are installed on one side of the water distributor 605.

[0028] like Figure 4 - Figure 9 As shown, when water supply is needed, the low-pressure water pump 602 installed inside the main frame 1 and close to the water tank 601 is started, and the water in the water tank 601 is pumped out through its pumping function. At this time, the water flow obtains initial power under the action of the low-pressure water pump 602 and enters the transportation link. The water flow then follows this connection path into the buffer pressure-stabilizing tank 603. The buffer pressure-stabilizing tank 603 can effectively alleviate the pressure fluctuations generated by the water flow during the transportation process, and plays a key role in stabilizing the water pressure. The water flow after pressure stabilization by the buffer pressure-stabilizing tank 603 is guided to the water distributor 605 installed at the other end, and the concentrated water flow delivered through the water supply pipe 604 is distributed to multiple water distribution pipes 606 installed on one side thereof. Finally, each water distribution pipe 606 transports the low-pressure water flow to different water use terminals, completing the entire low-pressure water supply process.

[0029] like Figure 6 and Figure 7 As shown, a docking block 7 is fixedly connected to the inside of the main frame 1 near the beating-up assembly 5, and a docking pipe 8 corresponding to the warp let-off assembly 3 is installed on the top of the docking block 7.

[0030] like Figure 10 and Figure 11 As shown, the interior of the docking block 7 is provided with a plurality of water pressure regulating mechanisms 9 for regulating the water pressure of the spray water, and the water pressure regulating mechanism 9 includes a regulating box 901 installed inside the docking block 7, and an regulating motor 902 is installed inside the regulating box 901, and the output end of the regulating motor 902 is fixedly connected to the driving gear 903, and the interior of the regulating box 901 is fixedly connected to a fixing plate 904 near the driving gear 903, and one side of the fixing plate 904 is rotatably connected to a transmission gear 905, and the other side of the transmission gear 905 is fixedly connected to an adjusting threaded rod 906.

[0031] like Figure 10 and Figure 11 The cam 908 is fixedly connected to the other side of the fixed plate 904 and the adjustment box 901, and the cam 908 is evenly distributed and fixed in parallel between the other side of the fixed plate 904 and the adjustment box 901, and the interior of the sliding block 908 is provided with a sliding sleeve that precisely fits the limit rod 907, so that the support force exerted on the sliding block 908 during movement is more balanced, avoiding the sliding block 908 from tilting or getting stuck due to uneven force, ensuring that it moves smoothly along a straight line, providing a stable basis for the precise displacement of the adjustment rod 910, and the sliding sleeve that precisely fits the limit rod 907 is provided inside the sliding block 908, which can greatly reduce the friction resistance between the sliding block 908 and the limit rod 907, making the movement of the sliding block 908 smoother and more flexible, reducing energy consumption and component wear during the adjustment process, and the sliding block 908 is slidably connected between the multiple limit rods 907, and one side of the sliding block 908 is installed with an adjusting screw The threaded rod 906 corresponds to the docking threaded tube 909, and the adjusting threaded rod 906 and the docking threaded tube 909 are threadedly connected. The thread parameters of the docking threaded tube 909 match the trapezoidal thread of the adjusting threaded rod 906. The trapezoidal thread itself has the characteristics of high transmission efficiency and strong bearing capacity. The matching of the parameters of the two can ensure the tightness of the threaded connection and reduce the gap, so that the rotational motion of the adjusting threaded rod 906 can be accurately converted into the linear motion of the docking threaded tube 909, thereby realizing the smooth and precise displacement of the sliding block 908 and the adjusting rod 910. The other side of the sliding block 908 is fixedly connected to the adjusting rod 910, and one side of the adjusting box 901 is fixedly connected to the positioning seat 911.

The interior of the low water pressure water supply mechanism 6 is provided with a connecting port 913 corresponding to the adjusting rod 910, and a plurality of connecting pipes 10 are installed between the interior of the docking block 7 and the docking pipe 8.

[0032] like Figure 10 and Figure 11As shown, the regulating box 901 installed inside the docking block 7 provides a stable installation and operation space for the entire mechanism. When the water pressure needs to be adjusted, the regulating motor 902 inside the regulating box 901 is started, and the driving gear 903 fixedly connected to its output end rotates accordingly. Since a fixed plate 904 is fixedly connected to the position near the driving gear 903 inside the regulating box 901, and the transmission gear 905 rotatably connected to one side of the fixed plate 904 is meshed with the driving gear 903, the rotation of the driving gear 903 will drive the transmission gear 905 to rotate synchronously, and the regulating threaded rod 906 fixedly connected to the other side of the transmission gear 905 will also rotate accordingly, and multiple limit switches fixedly connected between the other side of the fixed plate 904 and the regulating box 901 The rod 907 serves as a limit guide for the sliding block 908 that is slidably connected between them. The docking threaded tube 909 corresponding to the adjusting threaded rod 906 installed on one side of the sliding block 908 will drive the sliding block 908 to move along the limit rod 907 when the adjusting threaded rod 906 rotates, thereby causing the adjusting rod 910 fixedly connected on the other side of the sliding block 908 to be displaced. The two sealing rings 912 installed inside the positioning seat 911 fixedly connected to one side of the adjusting box 901 ensure the sealing of the adjusting rod 910 during the movement. The adjusting rod 910 will extend into the corresponding connecting port 913 installed inside the water distribution pipe 606, and the water pressure in the water distribution pipe 606 can be adjusted by changing the depth of the extension.

[0033] like Figure 12 and Figure 13 As shown, the other ends of the multiple connecting pipes 10 are each provided with an angle adjustment mechanism 11 for subsequent adjustment of the water spray angle. The angle adjustment mechanism 11 includes a fixed base pipe 1101 installed at one end of the butt-jointed pipe 8. The outer wall of the fixed base pipe 1101 is fixedly connected to a first drive assembly 1102 on one end of the outer wall. The output end of the first drive assembly 1102 is fixedly connected to a first adjustment gear 1103. The other end of the fixed base pipe 1101 is rotatably connected to a first movable pipe 1104. The outer wall of the first movable pipe 1104 is located near the first adjustment gear 1103. A first connecting gear ring 1105 is fixedly connected to the outer wall of the first movable tube 1104, a second driving assembly 1106 is installed near the other end, an output end of the second driving assembly 1106 is fixedly connected to a second adjusting gear 1107, the other end of the first movable tube 1104 is rotatably connected to the second movable tube 1108, an outer wall of the second movable tube 1108 is fixedly connected to a second connecting gear ring 1109 near the second adjusting gear 1107, and an outer wall of the second movable tube 1108 is installed near the other end. A third driving assembly 1110 is installed on the outer wall of the second movable tube 1108.

[0034] like Figure 12 and Figure 13As shown, the first drive assembly 1102, the second drive assembly 1106 and the third drive assembly 1110 are all servo motors, and their output shafts are fixedly connected to the corresponding adjusting gears by flat keys, which can ensure that the rotation amplitude of the first adjusting gear 1103, the second adjusting gear 1107 and the third adjusting gear 1111 is accurately controllable, thereby making the angle adjustment of the first movable tube 1104, the second movable tube 1108 and the third movable tube 1112 more precise, meeting the fine requirements of the angle in different scenarios, and the output shaft is fixedly connected to the corresponding adjusting gear by flat keys. The flat key connection structure is simple and easy to assemble and disassemble, which can ensure the circumferential fixation between the output shaft and the adjusting gear, making it more reliable when transmitting torque and avoiding relative sliding, ensuring that the power of the motor can be efficiently and stably transmitted to the adjusting gear, the output end of the third drive assembly 1110 is fixedly connected to the third adjusting gear 1111, and the other end of the second movable tube 1108 is rotatably connected to the third movable tube 1112. Deep groove ball bearings are installed at the rotating connections of the movable tube 1108, the second movable tube 1108 and the third movable tube 1112. The outer ring of the bearing has an interference fit with the tube body, and the inner ring has a clearance fit with the corresponding connecting shaft. The deep groove ball bearings can greatly reduce the friction resistance during the relative rotation of the movable tubes, making the angle adjustment process smoother and more flexible, and reducing power loss. The interference fit between the outer ring of the bearing and the tube body can ensure that the outer ring of the bearing is tightly combined with the tube body, avoiding loosening or relative displacement of the outer ring during the rotation of the movable tube, providing a stable installation foundation for the bearing, and ensuring its normal force and operation. The clearance fit between the inner ring and the corresponding connecting shaft reserves appropriate space for the rotation of the connecting shaft, reducing friction and wear between the inner ring and the connecting shaft, while allowing a certain amount of installation error and thermal expansion and contraction space to prevent rotation jamming due to over-tight fit. The outer wall of the third movable tube 1112 is fixedly connected to the third connecting gear ring 1113 near the third adjusting gear 1111, and the main frame 1 is provided with a winding assembly 12.

[0035] like Figure 12 and Figure 13As shown, when the angle needs to be adjusted, the first driving component 1102 at one end of the outer wall of the fixed base tube 1101 is started, and the first adjusting gear 1103 fixedly connected at its output end rotates accordingly. Since the first movable tube 1104 is rotatably connected at the other end of the fixed base tube 1101, its outer wall is fixedly connected to the position of the first adjusting gear 1103 near the first adjusting gear 1103, and the first connecting gear ring 1105 is meshed with the first adjusting gear 1103. The rotation of the first adjusting gear 1103 will drive the first connecting gear ring 1105 to rotate, thereby causing the first movable tube 1104 to rotate relative to the fixed base tube 1101, thereby achieving angle adjustment in the first direction. When the angle needs to be further adjusted, the second driving component 1106 at the other end of the outer wall of the first movable tube 1104 is started, and the second adjusting gear 1107 at its output end rotates. Since the second movable tube 1108 is rotatably connected at the other end of the first movable tube 1104, its outer wall is fixedly connected to the position of the second adjusting gear 1107 near the second adjusting gear 1107. There is a second connecting gear ring 1109 engaged with the second adjusting gear 1107. The rotation of the second adjusting gear 1107 will drive the second connecting gear ring 1109 to rotate, so that the second movable tube 1108 rotates relative to the first movable tube 1104, completing the angle adjustment in the second direction. If the angle needs to be adjusted, the third driving assembly 1110 at the other end of the outer wall of the second movable tube 1108 is started, and the third adjusting gear 1111 at the output end rotates. Since the third movable tube 1112 is rotatably connected to the other end of the second movable tube 1108, its outer wall is fixedly connected to the third connecting gear ring 1113 engaged with the third adjusting gear 1111 near the position of the third adjusting gear 1111. The rotation of the third adjusting gear 1111 will drive the third connecting gear ring 1113 to rotate, so that the third movable tube 1112 rotates relative to the second movable tube 1108, achieving angle adjustment in the third direction. Through the cooperation of these three levels of drive and transmission, the angle adjustment mechanism 11 can flexibly adjust the overall angle to meet different usage requirements.

[0036] The working principle of this embodiment is as follows: first, the warp yarn is transported through the warp feeding assembly 3 on the rear end of one side of the main frame 1, and the warp yarn forms a shed under the action of the opening assembly 4 on the top of the main frame 1, preparing for the subsequent weft insertion. The low-pressure water supply mechanism 6 inside the main frame 1 is started, and the water in the water tank 601 is pumped out by the low-pressure water pump 602, enters the buffer pressure stabilizing tank 603 to stabilize the water pressure, and then is transported to the water distributor 605 by the water supply pipe 604, and distributed to the water pressure regulating mechanism 9 in the docking block 7 through multiple water distribution pipes 606. In the water pressure regulating mechanism 9, the regulating motor 902 drives the driving gear 903 and the transmission gear 905 to rotate, driving the adjusting threaded rod 906 Rotate to move the sliding block 908 along the limit rod 907, and then adjust the water pressure by adjusting the depth of the connecting port 913 of the water distribution pipe 606 by extending the adjusting rod 910. The regulated water flows through the connecting pipe 10 and enters the angle adjustment mechanism 11. The three-stage driving components of the angle adjustment mechanism 11 respectively drive the corresponding adjusting gears to rotate, and the first movable tube 1104, the second movable tube 1108, and the third movable tube 1112 are rotated in sequence through the connecting gear ring transmission to accurately adjust the water spray angle and complete the water spray weft insertion. After the weft insertion, the beating assembly 5 inside the main frame 1 that cooperates with the opening assembly 4 tightens the weft yarn, and finally the winding assembly 12 winds up the woven fabric.
