Description

Technical Field

[0001] This invention relates to the field of rapier loom technology, and in particular to a rapier loom with low vibration operation. Background Technology

[0002] Rapier looms are the most widely used shuttleless looms. Besides possessing the high speed, high automation, and high efficiency of traditional shuttleless looms, their active weft insertion method offers strong adaptability, accommodating various types of yarns. Furthermore, rapier looms have a significant advantage in multi-color weft weaving, capable of producing yarn-dyed products with up to 16 weft colors. As shuttleless looms replace shuttle looms, rapier looms will become the main type of machine used for woven fabric production.

[0003] When a rapier loom is in operation, the transmitted warp threads are limited, and then the weft threads are introduced. The weft threads are then neatly arranged by the beat-up mechanism to realize the warp and weft weaving work. A high-speed rapier loom disclosed in CN 103993409 B has the following advantages: the warp trellis is connected to the rear of the frame, the take-up mechanism is installed below the frame, and the selvage trellis is installed on both sides of the warp trellis. This invention has the advantages of convenient operation, convenient warp tension adjustment, vertical lifting capability, and the ability to guide waste selvage.

[0004] However, in practical applications, the above-mentioned solution, like the traditional rapier loom, uses a cam to drive the reed to swing. The swing force is relatively large, and when the reed directly touches the warping device, there is a certain degree of vibration and noise. Long-term collisions can easily damage the reed, so further improvements are needed. Summary of the Invention

[0005] The purpose of this invention is to provide a rapier loom with low vibration operation, which has the effects of low vibration, low noise, high safety and stability, and long service life.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a rapier loom with low vibration operation, comprising a loom frame, wherein an unwinding roller, a take-up roller, a fixed frame, a reed, and a drive component for controlling the swing of the reed are respectively arranged on the loom frame, a warp setting device is arranged on the fixed frame, a reed seat is arranged at the lower end of the reed, and a vibration damping buffer mechanism is arranged between the reed seat and the fixed frame; the vibration damping buffer mechanism includes a rotating frame rotatably arranged on the side of the reed seat, a plurality of buffer springs connected to the reed seat are installed on one side of the rotating frame, and a spring-loaded insert is installed on the other side, and a spring-loaded plate and a plurality of air cushions connected to the spring-loaded plate are arranged on the side of the fixed frame near the spring-loaded insert.

[0007] By adopting the above technical solution, the warp yarns are unwound by the unwinding roller and the take-up roller. During weaving, the warp setting device positions the warp yarns, and the weft yarns are inserted through the weft insertion arrows on the loom. The drive unit controls the reed to swing intermittently to the right to beat the weft and realize the weaving operation. Each time the reed swings and touches the fixed frame, the reed seat pushes the rotating frame and the spring-loaded rod to the right, causing the spring-loaded rod to hit the spring-loaded plate. The rotating frame rotates accordingly, so that the spring-loaded rod, the buffer spring, and the air cushion are all subjected to force. Through their compression and buffering, the impact potential energy is reduced, which can reduce impact vibration and noise and reduce damage to the equipment.

[0008] A further feature of the present invention is that: both the front and rear ends of the rotating frame are provided with brackets for connecting the reed seat; both ends of the rebound plate are fixedly installed with limit frames; and both ends of the fixed frame are fixedly installed with sliding members that are slidably connected to the limit frames.

[0009] By adopting the above technical solution, the support can enhance the stability of the connection between the rotating frame and the reed seat, making the rotation of the rotating frame more stable. When the rebound plate is moved by force, the sliding part at the end is always sliding on the limit frame, so that the rebound plate slides smoothly.

[0010] A further embodiment of the present invention is that the spring-loaded insert includes multiple sets of fixed sleeves fixedly installed on one side of the rotating frame, a compression spring and a sliding block connected to the end of the compression spring are installed inside the fixed sleeve, and a slide rod that is slidably connected to the fixed sleeve is fixedly installed on the other side of the slide block, and a rubber push head is provided at the other end of the slide rod.

[0011] By adopting the above technical solution, the rotation of the rotating frame pushes the rebound rod closer to the rebound plate, causing the rubber pusher to strike the rebound plate. At the same time, the slide rod drives the sliding block to slide within the fixed sleeve, compressing the compression spring. Both the rubber pusher and the compression spring have a certain buffering capacity, which can further reduce the impact of vibration and noise.

[0012] A further configuration of the present invention is as follows: the driving component includes a motor and a driven wheel disposed on the outer wall of the loom frame; a driving wheel is installed at the output end of the motor; a synchronous belt connects the driven wheel and the driving wheel; an incomplete gear is coaxially mounted on the driven wheel; a rotating shaft and a rotating plate fixedly connected to the rotating shaft are disposed inside the loom frame; the upper end of the rotating plate is fixedly connected to the reed seat; and a driven gear meshing with the incomplete gear is installed at the end of the rotating shaft.

[0013] By adopting the above technical solution, the motor drives the rotation of the driving wheel, which in turn drives the synchronous belt to rotate the driven wheel. The meshing of the incomplete gears drives the driven gear to rotate, and the rotating shaft drives the rotating plate to rotate, causing the reed to swing and perform weft insertion, thus realizing the weaving of warp and weft threads.

[0014] A further embodiment of the present invention is that the driving component further includes a reciprocating mechanism disposed within the loom frame for pushing the rotating plate to reset, and a lubrication component for lubricating the incomplete gear, the driven gear, and the rotating shaft. The reciprocating mechanism includes a U-shaped limiting rod installed within the loom frame and slidably connected to the rotating plate. The U-shaped limiting rod is provided with two sets of stops and a return spring that abuts against one set of stops and the rotating plate.

[0015] By adopting the above technical solution, when the incomplete gear disengages from the driven gear, the return spring in a compressed state pushes the rotating plate back, causing the reed to reset. When engaged, the reed weaves again, thereby realizing a cyclic weft weaving operation. The lubrication components can lubricate the incomplete gear, driven gear, and rotating shaft, avoiding vibration and equipment damage caused by rotation jamming or other reasons.

[0016] A further embodiment of the present invention is that the lubrication component includes a lubricant tank, a pump, and a noise sensor installed on the outer wall of the loom frame. Two sets of lubricant nozzles, corresponding to the incomplete gear and the driven gear respectively, are provided above the lubricant tank. Delivery pipes are provided at both ends of the pump, connecting the lubricant nozzles and the bottom of the lubricant tank respectively.

[0017] By adopting the above technical solution, the noise sensor monitors the surrounding noise. When the noise is high, it indicates that the rotation of the incomplete gear, driven gear, and rotating shaft is not sensitive enough. This allows for automatic control of the extraction pump to extract the lubricant from the lubricant tank and apply it through the delivery pipe and lubricant nozzle. This enables automatic and timely maintenance, improves the sensitivity of equipment operation, and reduces jamming and vibration.

[0018] A further feature of the present invention is that the outer wall of the loom frame is provided with multiple sets of fixing blocks for fixing the delivery pipe, and the upper end face of the lubricant tank is provided as an opening.

[0019] By adopting the above technical solution, the fixing block is used to install and position the delivery pipe. When spraying lubricant, excess lubricant can fall from the opening into the lubricant tank for recycling and reuse, which saves more costs.

[0020] A further configuration of the present invention is as follows: the warping device includes electric push rods installed at both ends of the fixed frame, a pressure frame is installed between the output ends of the two sets of electric push rods, a limit roller is provided on the fixed frame, and a pressure roller corresponding to the limit roller is provided on the pressure frame.

[0021] By adopting the above technical solution, when performing weft threading, the electric push rod is first controlled to drive the lower pressure frame to move down, so that the lower pressure roller moves down and presses the warp thread through the limit roller, which facilitates the weft threading arrow to perform rapid weft threading.

[0022] A further provision of the present invention is that: a guide roller for conveying yarn is provided on the loom frame, and a transmission component for driving the unwinding roller and the take-up roller to rotate synchronously is also provided on the outer wall of the loom frame.

[0023] By adopting the above technical solution, the warp yarn is conveyed under the control of the transmission component, and weft yarn is automatically knitted. The transmission component is an existing belt pulley structure that can make the unwinding roller and the take-up roller rotate synchronously, so it will not be described in detail here. With the support of the guide roller, the warp yarn can be conveyed smoothly.

[0024] The beneficial effects of this invention are:

[0025] 1. This invention features a vibration damping and buffering mechanism on the side of the reed. When the drive unit is weaving, the reed seat pushes the rotating frame and the spring-loaded rod to the right, causing the spring-loaded rod to strike the spring-loaded plate. The rotating frame rotates accordingly, causing the spring-loaded rod, the buffer spring, and the air cushion to all be stressed. When the spring-loaded rod is stressed, the sliding rod causes the sliding block to slide within the fixed sleeve, compressing the compression spring. Both the rubber pusher and the compression spring have a certain degree of buffering. With the vibration damping and buffering effect of the spring-loaded rod, the buffer spring, and the air cushion, the impact potential energy can be greatly reduced, thus reducing impact vibration and noise and minimizing damage to the equipment.

[0026] 2. When the drive component of this invention is working, the motor drives the rotation of the driving wheel, which in turn drives the synchronous belt to rotate the driven wheel. The meshing of the incomplete gears pushes the driven gear to rotate, and the rotating shaft drives the rotating plate to rotate, causing the reed to swing. This squeezes the return spring, performing weft insertion. When disengaging, the return spring pushes the rotating plate back, restoring the reed to its original position. Through intermittent meshing, the reed is driven to swing back and forth, thereby realizing a cyclic weft insertion and weaving operation. This structure uses gear meshing and the elastic push of the spring to achieve weft insertion. Compared with the traditional method of using cam rotation and impact to achieve weft insertion, it can greatly reduce the impact of vibration and noise, and improve the safety and stability of the device.

[0027] 3. The present invention also includes a lubrication component. A noise sensor monitors nearby noise. When the noise is loud, it indicates that the rotation of the incomplete gear, driven gear, and rotating shaft is not sensitive enough. This allows the pump to be automatically controlled to extract the lubricant from the lubricant tank and apply it through the delivery pipe and lubricant nozzle. This enables automatic and timely maintenance, improves the sensitivity of equipment operation, and reduces the impact of jamming and vibration. Attached Figure Description

[0037] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a low-vibration rapier loom includes a loom frame 1. The loom frame 1 is respectively equipped with an unwinding roller 9, a take-up roller 8, a fixed frame 5, a reed 7, and a drive component 3 for controlling the oscillation of the reed 7. The fixed frame 5 is equipped with a warp-setting device 2. A reed seat 71 is provided at the lower end of the reed 7. A vibration-damping buffer mechanism 6 is provided between the reed seat 71 and the fixed frame 5. The vibration-damping buffer mechanism includes a rotating frame 61 rotatably mounted on the side of the reed seat 71. Multiple buffer springs 63 connecting the reed seat 71 are installed on one side of the rotating frame 61, and a spring-loaded insert 64 is installed on the other side. The fixed frame 5 is equipped with a spring-loaded plate 65 and a connecting spring-loaded plate on the side near the spring-loaded insert 64. Multiple air cushions 66 of 65; the warp yarns are unwound by the unwinding roller 9 and the take-up roller 8. During weaving, the warp setting device 2 positions the warp yarns and the weft yarns are inserted by the weft insertion arrow on the loom. The drive unit 3 controls the reed 7 to swing intermittently to the right to beat the weft and realize the weaving operation. Each time the reed 7 swings and touches the fixed frame 5, the reed seat 71 pushes the rotating frame 61 and the spring-loaded rod 64 to move to the right, so that the spring-loaded rod 64 hits the spring-loaded plate 65. The rotating frame 61 rotates accordingly, so that the spring-loaded rod 64, the buffer spring 63 and the air cushion 66 are all subjected to force. Through their compression buffer, the impact potential energy is reduced, which can reduce impact vibration and noise and reduce damage to the equipment.

[0039] like Figure 3 As shown, the front and rear ends of the rotating frame 61 are provided with brackets 62 for connecting the reed seat 71, and the two ends of the rebound plate 65 are fixedly installed with limit frames 67. The two ends of the fixed frame 5 are fixedly installed with sliding parts 68 that are slidably connected to the limit frames 67. The brackets 62 can enhance the stability of the connection between the rotating frame 61 and the reed seat 71, making the rotation of the rotating frame 61 more stable. When the rebound plate 65 is moved by force, the sliding parts 68 at the end are always sliding on the limit frames 67, so that the rebound plate 65 slides smoothly.

[0040] like Figure 4As shown, the spring-loaded insert 64 includes multiple sets of fixed sleeves 641 fixedly installed on one side of the rotating frame 61. A compression spring 642 and a sliding block 643 connected to the end of the compression spring 642 are installed inside the fixed sleeve 641. A slide rod 644 slidably connected to the fixed sleeve 641 is fixedly installed on the other side of the slide block 643. A rubber push head 645 is provided at the other end of the slide rod 644. By adopting the above technical solution, the rotation of the rotating frame 61 pushes the spring-loaded insert 64 closer to the spring-loaded plate 65, causing the rubber push head 645 to strike the spring-loaded plate 65. At the same time, the slide rod 644 drives the sliding block 643 to slide inside the fixed sleeve 641, compressing the compression spring 642. Both the rubber push head 645 and the compression spring 642 have a certain buffering capacity, which can further reduce the impact of vibration and noise.

[0041] like Figure 5 As shown, the driving component 3 includes a motor 31 and a driven wheel 34 disposed on the outer wall of the loom frame 1. A driving wheel 32 is installed at the output end of the motor 31. A synchronous belt 33 connects the driven wheel 34 and the driving wheel 32. An incomplete gear 35 is coaxially mounted on the driven wheel 34. A rotating shaft 37 and a rotating plate 310 fixedly connected to the rotating shaft 37 are disposed inside the loom frame 1. The upper end of the rotating plate 310 is fixedly connected to the reed seat 71. A driven gear 36 that meshes with the incomplete gear 35 is installed at the end of the rotating shaft 37. When the motor 31 is driven, the rotation of the driving wheel 32 drives the synchronous belt 33 to rotate the driven wheel 34. The meshing of the incomplete gear 35 pushes the driven gear 36 to rotate, and the rotating shaft 37 drives the rotating plate 310 to rotate, causing the reed 7 to swing and perform weft insertion, thereby realizing the weaving of warp and weft threads.

[0042] like Figure 5 As shown, the drive component 3 also includes a reciprocating mechanism 39 disposed within the loom frame 1 for pushing the rotating plate 310 to reset, and a lubrication component 38 for lubricating the incomplete gear 35, the driven gear 36, and the rotating shaft 37. The reciprocating mechanism 39 includes a U-shaped limiting rod 391 installed within the loom frame 1 and slidably connected to the rotating plate 310. The U-shaped limiting rod 391 is provided with two sets of stops 392 and a return spring 393 that abuts against one set of stops 392 and the rotating plate 310. When the incomplete gear 35 disengages from the driven gear 36, the return spring 393, which is in a compressed state, pushes the rotating plate 310 back, causing the reed 7 to reset. When engaged, the reed 7 weaves again, thereby realizing a cyclic weft-beating weaving operation. The lubrication component 38 can lubricate the incomplete gear 35, the driven gear 36, and the rotating shaft 37, avoiding vibration and equipment damage caused by rotation jamming or other reasons.

[0043] like Figure 5As shown, the lubrication component 38 includes a lubricant tank 381, a pump 383, and a noise sensor 386 installed on the outer wall of the loom frame 1. Two sets of lubricant nozzles 385, corresponding to the incomplete gear 35 and the driven gear 36 respectively, are arranged above the lubricant tank 381. Delivery pipes 382, ​​connecting the lubricant nozzles 385 and the bottom of the lubricant tank 381, are provided at both ends of the pump 383. The noise sensor 386 monitors nearby noise; when the noise is high, it indicates that the rotation of the incomplete gear 35, the driven gear 36, and the rotating shaft 37 is not sensitive enough. Therefore, the pump 383 can be automatically controlled to extract lubricant from the lubricant tank 381 and apply it through the delivery pipes 382 and the lubricant nozzles 385, thus enabling automatic and timely maintenance, improving the sensitivity of equipment operation, and reducing jamming and vibration.

[0044] like Figure 5 As shown, the outer wall of the loom frame 1 is provided with multiple sets of fixing blocks 384 for fixing the conveying pipe 382, ​​and the upper end face of the lubricant tank 381 is set as an opening; the fixing blocks 384 are used to install and position the conveying pipe 382. When spraying lubricant, excess lubricant can fall into the lubricant tank 381 from the opening for recycling and reuse, which saves more costs.

[0045] like Figure 6 As shown, the warp setting device 2 includes electric push rods 21 installed at both ends of the fixed frame 5. A lower pressure frame 22 is installed between the output ends of the two sets of electric push rods 21. A limit roller 24 is provided on the fixed frame 5, and a lower pressure roller 23 corresponding to the limit roller 24 is provided on the lower pressure frame 22. When performing weft threading, the electric push rods 21 are first controlled to drive the lower pressure frame 22 to move down, so that the lower pressure roller 23 moves down and presses the warp thread through the limit roller 24, which facilitates the rapid weft threading operation of the weft arrow.

[0046] like Figure 7 As shown, the loom frame 1 is equipped with a guide roller 4 for conveying the yarn, and the outer wall of the loom frame 1 is also equipped with a transmission component 10 for driving the unwinding roller 9 and the take-up roller 8 to rotate synchronously. The transmission component 10 controls the warp yarn conveying and performs automatic weft knitting. The transmission component 10 is an existing belt pulley matching structure, which can make the unwinding roller 9 and the take-up roller 8 rotate synchronously, so it will not be described in detail here. With the support of the guide roller 4, the warp yarn can be conveyed smoothly.
