Description

Technical Field

[0001] This utility model relates to the field of water jet loom technology, and in particular to a multi-arm sheathing device for a water jet loom. Background Technology

[0002] During the operation of a water jet loom, the quality and stability of the woven fabric play a crucial role in the quality of the final product.

[0003] However, during the weaving process, dust, fiber debris and other impurities often adhere to the surface of the fabric. These impurities not only affect the appearance quality of the fabric, but may also cause problems in subsequent processing, such as causing surface defects and affecting the uniformity of dyeing.

[0004] Traditional multi-arm sheathing devices on water jet looms have certain limitations in handling fabric impurities. They cannot flexibly and effectively clean fabrics according to different fabric characteristics (such as thickness and material), making it difficult to meet diverse production needs. At the same time, during the fabric transport process, factors such as changes in fabric tension and machine vibration can easily cause the position of components such as the cleaning mechanism to shift, affecting the cleaning effect and the working stability of the entire device, thereby affecting the production efficiency and quality of the fabric.

[0005] Therefore, we propose a multi-arm sheathing device for water jet looms. Utility Model Content

[0006] The main objective of this invention is to provide a multi-arm shedding device for water jet looms. This device aims to prevent impurities such as dust and fiber debris adhering to the fabric surface from affecting the fabric's appearance quality, causing surface defects in subsequent processing, and impacting dyeing uniformity. It also addresses issues arising from the limitations of traditional multi-arm shedding devices on water jet looms in effectively cleaning according to different fabric characteristics, as well as the positional shift of cleaning mechanisms and other components during fabric transport, which can affect cleaning effectiveness, device stability, fabric production efficiency, and quality. This invention improves fabric quality and production efficiency, meets diverse production needs, and ensures the quality of the final product, effectively solving the problems in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A multi-arm sheathing device for a water jet loom includes a machine housing and a weaving body. A support frame is fixedly connected to the top of the machine housing. From top to bottom, the inner side of the support frame is provided with a feed roller, a cleaning mechanism, a first guide roller, and a second guide roller. The cleaning mechanism includes a rubber roller assembly, and the rubber roller assembly is connected to one side of the support frame through an adjusting component.

[0009] The rubber roller assembly includes a support plate, and two opposing support plates are provided on one side of the support plate. A rubber roller is rotatably connected to the inner side of the two support plates. The rubber roller is composed of a roller core and an adhesive layer bonded to the outside of the roller core. The fabric body passes through the feed roller, the rubber roller, the first guide roller and the second guide roller in sequence.

[0010] By adopting the above technical solution, the fabric body first passes through the feed roller, which guides and initially conveys the fabric, allowing it to enter the subsequent processing stage at a suitable angle and position. Then, the fabric passes through the rubber roller, which consists of a roller core and an adhesive layer bonded to the outside of the roller core. The rubber roller can clean the surface of the fabric, as the adhesive layer absorbs impurities on the fabric. After being processed by the rubber roller, the fabric then passes through the first guide roller and the second guide roller in sequence and falls to the bottom of the support frame. The first guide roller and the second guide roller mainly guide the fabric to be transported along the correct path inside the machine box and the support frame, ensuring that the fabric can pass through the entire device smoothly and evenly, providing a good fabric condition for subsequent weaving operations.

[0011] The rubber roller assembly is connected to one side of the support frame via an adjusting component. The support plate in the rubber roller assembly supports the rubber roller and is rotatably connected to it by two opposing support plates on one side. When the fabric body passes over the surface of the rubber roller, the movement of the fabric will cause the rubber roller to rotate because the rubber roller is rotatably connected to the inside of the support plates. The rubber layer of the rubber roller can adsorb dust, fiber debris and other impurities on the surface of the fabric. The adjusting component can adjust the position of the rubber roller assembly. For example, according to factors such as the thickness of the fabric and the required level of cleanliness, the contact pressure and other parameters between the rubber roller and the fabric body can be changed by adjusting the component. This can better adapt to the cleaning needs of different fabrics and ensure the stability and reliability of the cleaning effect.

[0012] Furthermore, the adjustment assembly includes a support rod that is vertically and fixedly connected to the support frame, and multiple support rods are provided. A sliding rod is slidably connected to the outside of the support rod, and a sliding sleeve is slidably connected to the outside of the sliding rod. One end of the sliding sleeve is connected to the support plate.

[0013] By adopting the above technical solution, when it is necessary to adjust the horizontal position of the support plate, since the slide rod and the support rod are slidably connected, and the sliding sleeve is slidably connected to the slide rod with one end connected to the support plate, the horizontal position can be adjusted by changing the position of the sliding sleeve on the slide rod.

[0014] Furthermore, a spring is connected between one end of the slide rod and one side of the support frame, and the spring is sleeved on the support rod.

[0015] By adopting the above technical solution, when the slide bar slides on the support rod under the action of external force, the spring connected to one end of the slide bar and one side of the support frame will deform. The spring is a compression spring with an elastic coefficient of 5 N / mm and a natural length of 50 mm. During the operation of the equipment, sudden changes in fabric tension and machine vibration are the main external force sources for the displacement of the slide bar. For example, when the slide bar is subjected to the impact force generated by the sudden change in fabric tension, according to Hooke's Law F = kx (where F is the external force on the spring, k is the elastic coefficient, and x is the spring compression), within the elastic limit of the spring, its compression stroke is ≤10 mm. During this process, the spring can effectively absorb the impact energy, convert kinetic energy into elastic potential energy, buffer the instantaneous impact force, and thus prevent the device from being damaged by sudden external forces. When the external force disappears, the spring relies on its own elastic restoring force and, based on its stored elastic potential energy, pushes the slide bar back to its original position or close to its original position, realizing the reset function. This characteristic helps to maintain the stability of the device and ensures that the relative position and contact pressure parameters between the rubber roller and the fabric body can return to normal, thereby ensuring the normal operation of the cleaning mechanism.

[0016] Furthermore, the outer side of the slide rod has multiple sets of equally spaced threaded holes, and the outer side of the slide sleeve near the threaded holes has a threaded through hole for connection with a bolt. One end of the bolt passes through the threaded through hole and is threadedly connected to the threaded hole.

[0017] By adopting the above technical solution, when it is necessary to adjust the position of the support plate and the rubber roller assembly connected thereto, the bolts are first loosened. Since the bolts were originally connected to the threaded holes on the slide rod and the threaded through holes on the slide sleeve, after being loosened, the slide sleeve is no longer fixed in the current position of the slide rod. At this time, the operator can slide the slide sleeve along the horizontal direction of the slide rod, thereby moving the support plate and the rubber roller assembly to the appropriate position. Because there are multiple sets of equally spaced threaded holes on the outside of the slide rod, the slide sleeve can be adjusted in multiple selectable positions on the slide rod to meet different work requirements, such as adjusting the contact position and pressure between the rubber roller and the fabric body according to factors such as the thickness of the fabric and cleaning requirements.

[0018] Once the sliding sleeve has slid to the target position, the bolt is passed through the threaded hole on the sliding sleeve and threadedly connected to the corresponding threaded hole on the sliding rod. By tightening the bolt, the threaded engagement between the bolt and the threaded hole generates significant friction and axial tension, thus firmly fixing the sliding sleeve to the sliding rod. In this way, the support plate and the rubber roller assembly are stably fixed in their current positions, ensuring that the rubber roller can perform cleaning and other operations on the fabric body in a stable position and state during the operation of the water jet loom. This prevents positional displacement due to vibration or other external forces, ensuring the working stability and reliability of the entire multi-arm sheathing device.

[0019] Furthermore, a water tank and multiple water pumps arranged at equal intervals at both ends of the water tank are fixedly installed on the bottom inner wall of the casing. A first water pipe is fixedly connected to the suction end of the water pump. The end of the first water pipe away from the water pump is fixedly installed on the lower side of the water tank and communicates with the inside of the water tank. A second water pipe is fixedly installed at the discharge end of the water pump. The second water pipe passes through the casing and the support frame and is fixedly connected to a nozzle.

[0020] By adopting the above technical solution, the water tank 17 is used to store the water required for the operation of the water jet loom. When water needs to be sprayed, the water pump 18 on the inner wall of the bottom of the machine box 1 is started. The suction end of the water pump 18 is connected to the lower side of the water tank 17 through the first water pipe 19. As the water pump 18 generates suction, the water in the water tank 17 will be sucked into the water pump 18 along the first water pipe 19. Then, the water is discharged from the discharge end under the action of the water pump 18 and transported to the nozzle 21 through the fixedly installed second water pipe 20, which passes through the machine box 1 and the support frame 2. Finally, the nozzle 21 sprays the water out in a certain shape and pressure, aiming at the weft insertion work of the woven fabric after the rubber roller is cleaned.

[0021] Furthermore, the top of the chassis is provided with a water inlet, and the top of the water tank is provided with a water inlet connected to the water inlet, and a filter screen is installed inside the water inlet.

[0022] By adopting the above technical solution, the water inlet is opened at the top of the casing, and the water sprayed from the nozzle flows smoothly into the water tank through the water inlet and the water inlet at the top of the water tank.

[0023] The filter screen installed inside the water inlet serves to filter impurities. During the water filling process, the water may contain various impurities, such as dust, fiber debris, and small solid particles. When water enters the water tank through the inlet, the filter screen intercepts these impurities. For example, if the water contains fine sand particles, these particles will be blocked on the outside of the filter screen as the water flows through it, while clean water can pass through the filter screen into the water tank. This prevents impurities from entering the water tank and accumulating inside, thus preventing impurities from being sucked into the water pipe by the water pump and damaging components such as the water pump and nozzles, ensuring the normal operation of the entire water spray system.

[0024] Furthermore, a water inlet pipe is fixedly connected to the upper side of the water tank, and the end of the water inlet pipe away from the water tank extends through the casing to the outside. A valve is installed on the water inlet pipe.

[0025] By adopting the above technical solution, the water inlet pipe is fixedly connected to the upper side of the water tank, with one end extending through the machine casing to the outside. This design facilitates adding water to the water tank from outside the machine casing. When the water level in the tank is lower than the required working level, the operator can open the valve on the water inlet pipe. At this time, external water sources such as water pipes or buckets can fill the water tank through the water inlet pipe. Since the water inlet pipe is connected to the upper side of the water tank, it ensures that water flows smoothly into the tank. The valve on the water inlet pipe controls the water flow. When water needs to be added, the valve is opened, and water flows into the water tank through the water inlet pipe. When the water level in the tank reaches the appropriate height, the valve is closed, and water addition stops. By controlling the opening and closing of the valve, the water level in the tank can be precisely controlled, avoiding overfilling and overflow, or underfilling and affecting the normal operation of the water jet loom. At the same time, the presence of the valve also prevents water in the tank from flowing out through the water inlet pipe when it is not in use, ensuring a stable water level in the tank.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) The present invention provides a multi-arm shedding device for a water jet loom. By setting a rubber roller consisting of a roller core and an external rubber layer, the rubber layer can effectively adsorb impurities such as dust and fiber debris on the surface of the fabric. During the process of the fabric body passing through the feed roller, the rubber roller, the first guide roller and the second guide roller in sequence, the fabric is efficiently cleaned, providing a clean fabric condition for subsequent weaving operations, significantly improving the quality of the fabric, reducing fabric defects caused by impurities, and increasing the yield of the product.

[0028] (2) The present invention provides a multi-arm shedding device for a water jet loom. The design of the adjustment component allows the position of the rubber roller assembly to be flexibly adjusted according to factors such as the thickness of the fabric and the cleanliness requirements. The sliding connection between the slide rod and the support rod, as well as the sliding connection between the slide sleeve and the slide rod, together with multiple sets of equally spaced threaded holes on the slide rod and threaded through holes and bolts on the slide sleeve, can accurately change the contact position and pressure between the rubber roller and the fabric body to meet the cleaning needs of different fabrics. At the same time, the spring connected between one end of the slide rod and the support frame can buffer the impact of external forces caused by changes in fabric tension and machine vibration during equipment operation, prevent damage to the device, and achieve reset after the force disappears, ensuring that the relative position and contact pressure between the rubber roller and the fabric body return to normal, maintaining the stability of the device, ensuring that the entire multi-arm shedding device works stably and reliably, and improving production efficiency.

[0033] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0034] To prevent dust, fiber debris, and other impurities adhering to the fabric surface from affecting its appearance quality, causing surface defects and impacting dyeing uniformity during subsequent processing, and to address issues arising from the inability of traditional water-jet looms' multi-arm sheathing devices to effectively clean according to different fabric characteristics, as well as the impact of cleaning mechanism misalignment during fabric transport on cleaning effectiveness, device stability, weaving efficiency, and quality, this approach aims to improve fabric quality and production efficiency, meet diverse production needs, and ensure the quality of the final product. Figure 1 , Figure 2 , Figure 3 As shown, a multi-arm sheathing device for a water jet loom includes a machine housing 1 and a weaving body 16. A support frame 2 is fixedly connected to the top of the machine housing 1. From top to bottom, the inner side of the support frame 2 is provided with a feed roller 3, a cleaning mechanism, a first guide roller 4 and a second guide roller 5. The cleaning mechanism includes a rubber roller assembly, and the rubber roller assembly is connected to one side of the support frame 2 through an adjustment assembly.

[0035] The rubber roller assembly includes a support plate 6. Two opposing support plates 7 are provided on one side of the support plate 6. A rubber roller is rotatably connected to the inner side of the two support plates 7. The rubber roller is composed of a roller core 8 and an adhesive layer 9 bonded to the outside of the roller core 8. The fabric body 16 passes through the feed roller 3, the rubber roller, the first guide roller 4 and the second guide roller 5 in sequence.

[0036] In use, the fabric body 16 first passes through the feed roller 3, which guides and initially conveys the fabric, allowing it to enter the subsequent processing stage at a suitable angle and position. Then, the fabric passes through the rubber roller, which consists of a roller core 8 and an adhesive layer 9 bonded to the outside of the roller core 8. The rubber roller can clean the surface of the fabric, as the adhesive layer 9 absorbs impurities on the fabric. After being processed by the rubber roller, the fabric then passes through the first guide roller 4 and the second guide roller and falls to the bottom of the support frame 2. The first guide roller 4 and the second guide roller 5 mainly guide the fabric to pass through the correct path inside the machine box 1 and the support frame 2, ensuring that the fabric can pass through the entire device smoothly and evenly, providing a good fabric condition for subsequent weaving operations.

[0037] The rubber roller assembly is connected to one side of the support frame 2 via an adjusting component. The support plate 6 in the rubber roller assembly supports the rubber roller and is rotatably connected to the rubber roller by two opposing support plates 7 on one side. When the fabric body 16 passes over the surface of the rubber roller, the movement of the fabric will drive the rubber roller to rotate because the rubber roller is rotatably connected to the inside of the support plate 7. The rubber layer 9 of the rubber roller can adsorb dust, fiber debris and other impurities on the surface of the fabric. The adjusting component can adjust the position of the rubber roller assembly. For example, according to factors such as the thickness of the fabric and the required level of cleanliness, the contact pressure and other parameters between the rubber roller and the fabric body 16 can be changed by adjusting the component. This can better adapt to the cleaning needs of different fabrics and ensure the stability and reliability of the cleaning effect.

[0038] For example, such as Figure 2 , Figure 3 As shown, the present invention also includes an adjustment assembly comprising a support rod 10 that is vertically fixedly connected to the support frame 2, and multiple support rods 10 are provided. A slide rod 11 is slidably connected to the outside of the support rod 10, and a slide sleeve 12 is slidably connected to the outside of the slide rod 11. One end of the slide sleeve 12 is connected to the support plate 6.

[0039] When it is necessary to adjust the horizontal position of the support plate 6 during use, since the slide rod 11 is slidably connected to the support rod 10, and the slide sleeve 12 is slidably connected to the slide rod 11 with one end of the slide sleeve 12 connected to the support plate 6, the horizontal position can be adjusted by changing the position of the slide sleeve 12 on the slide rod 11.

[0040] For example, such as Figure 3 As shown, the present invention also includes a spring 13 connected between one end of the slide rod 11 and one side of the support frame 2, and the spring 13 is sleeved on the support rod 10.

[0041] When the slide rod 11 is subjected to external force and slides on the support rod 10, the spring 13 connected to one end of the slide rod 11 and one side of the support frame 2 will deform. The spring 13 is a compression spring with an elastic coefficient of 5N / mm and a natural length of 50mm. During the operation of the equipment, sudden changes in fabric tension and machine vibration are the main external force sources for the displacement of the slide rod 11. For example, when the slide bar 11 is subjected to an impact force caused by a sudden change in fabric tension, according to Hooke's Law F = kx (where F is the external force on the spring, k is the elastic coefficient, and x is the spring compression), within the elastic limit of the spring, its compression stroke is ≤10mm. During this process, the spring 13 can effectively absorb the impact energy, convert kinetic energy into elastic potential energy, buffer the instantaneous impact force, and thus prevent the device from being damaged by a sudden external force. When the external force disappears, the spring 13 relies on its own elastic restoring force and, based on its stored elastic potential energy, pushes the slide bar 11 back to its original position or close to its original position, realizing the reset function. This characteristic helps to maintain the stability of the device and ensures that the relative position and contact pressure between the rubber roller and the fabric body 16 can return to normal, thereby ensuring the normal operation of the cleaning mechanism.

[0042] For example, such as Figure 3 As shown, the present invention also includes multiple sets of equally spaced threaded holes 14 on the outer side of the slide rod 11, and a threaded through hole for connection with a bolt 15 on the outer side of the slide sleeve 12 near the threaded holes 14. One end of the bolt 15 passes through the threaded through hole and is threadedly connected to the threaded hole 14.

[0043] When in use, when it is necessary to adjust the position of the support plate 6 and the rubber roller assembly connected thereto, first loosen the bolt 15. Since the bolt 15 was originally connected to the threaded hole 14 on the slide rod 11 and the threaded through hole on the slide sleeve 12, after loosening, the slide sleeve 12 is no longer fixed in the current position of the slide rod 11. At this time, the operator can slide the slide sleeve 12 along the horizontal direction of the slide rod 11, thereby moving the support plate 6 and the rubber roller assembly to the appropriate position. Because the slide rod 11 has multiple sets of equally spaced threaded holes 14 on the outside, the slide sleeve 12 can be adjusted to multiple selectable positions on the slide rod 11 to meet different work requirements, such as adjusting the contact position and pressure between the rubber roller and the fabric body 16 according to factors such as the thickness of the fabric and cleaning requirements.

[0044] After the sliding sleeve 12 slides to the target position, the bolt 15 is passed through the threaded through hole on the sliding sleeve 12 and threadedly connected to the corresponding threaded hole 14 on the sliding rod 11. By tightening the bolt 15, the threaded engagement between the bolt 15 and the threaded hole 14 will generate a large frictional force and axial tensile force, thereby firmly fixing the sliding sleeve 12 to the sliding rod 11. In this way, the support plate 6 and the rubber roller assembly are stably fixed in the current position, ensuring that the rubber roller can perform cleaning and other operations on the fabric body 16 in a stable position and state during the operation of the water jet loom, avoiding positional displacement due to vibration or other external forces, and ensuring the working stability and reliability of the entire multi-arm sheathing device.

[0045] For example, such as Figure 1 As shown, this utility model also includes a water tank 17 and a plurality of water pumps 18 arranged at equal intervals at both ends of the water tank 17, which are fixedly installed on the bottom inner wall of the casing 1. The suction end of the water pump 18 is fixedly connected to a first water pipe 19. The end of the first water pipe 19 away from the water pump 18 is fixedly installed on the lower part of one side of the water tank 17 and communicates with the inside of the water tank 17. The discharge end of the water pump 18 is fixedly installed with a second water pipe 20. The second water pipe 20 passes through the casing 1 and the support frame 2 and is fixedly connected to a nozzle 21.

[0046] In use, the water tank 17 is used to store the water required for the operation of the water jet loom. When water is needed, the water pump 18 on the inner wall of the bottom of the machine housing 1 is started. The suction end of the water pump 18 is connected to the lower side of the water tank 17 through the first water pipe 19. As the water pump 18 generates suction, the water in the water tank 17 is sucked into the water pump 18 along the first water pipe 19. Then, the water is discharged from the discharge end under the action of the water pump 18 and transported to the nozzle 21 through the fixedly installed second water pipe 20, which passes through the machine housing 1 and the support frame 2. Finally, the nozzle 21 sprays the water out in a certain shape and pressure, aiming at the weft insertion work of the fabric after the rubber roller has been cleaned.

[0047] For example, such as Figure 1 As shown, the present invention also includes a water inlet 22 on the top of the casing 1, a water inlet connected to the water inlet 22 on the top of the water tank 17, and a filter screen 23 installed inside the water inlet.

[0048] When in use, the water inlet 22 is located on the top of the casing 1, and the water sprayed from the nozzle 21 flows smoothly into the water tank 17 through the water inlet 22 and the water inlet on the top of the water tank 17.

[0049] The filter screen 23 installed inside the water inlet serves to filter impurities. During the water filling process, the water may contain various impurities, such as dust, fiber debris, and small solid particles. When water enters the water tank 17 through the water inlet 22, the filter screen 23 will intercept these impurities. For example, if the water contains fine sand particles, when the water flows through the filter screen 23, the sand particles will be blocked on the outside of the filter screen 23, while clean water can pass through the filter screen 23 into the water tank 17. This prevents impurities from entering the water tank 17, avoids the accumulation of impurities in the water tank 17, and thus prevents impurities from being sucked into the water pipe by the water pump 18, which could damage the water pump 18 and the nozzle 21, ensuring the normal operation of the entire water spraying system.

[0050] For example, such as Figure 1 As shown, the present invention also includes a water inlet pipe 24 fixedly connected to the upper part of one side of the water tank 17. The end of the water inlet pipe 24 away from the water tank 17 extends through the casing 1 to the outside. A valve is provided on the water inlet pipe 24.

[0051] In use, the water inlet pipe 24 is fixedly connected to the upper side of the water tank 17, with one end extending through the casing 1 to the outside. This design facilitates adding water to the water tank 17 from outside the casing. When the water level in the water tank 17 is lower than the required working level, the operator can open the valve on the water inlet pipe 24. At this time, external water sources such as water pipes or buckets can fill the water tank 17 through the water inlet pipe 24. Because the water inlet pipe 24 is connected to the upper side of the water tank 17, it ensures that water flows smoothly into the water tank 17. The valve on the water inlet pipe 24... The valve controls the water flow. When water needs to be added, the valve is opened, and water flows into the water tank 17 through the water inlet pipe 24. When the water level in the water tank 17 reaches the appropriate height, the valve is closed to stop adding water. By controlling the opening and closing of the valve, the water level in the water tank 17 can be precisely controlled to avoid overfilling and overflow, or underfilling and affecting the normal operation of the water jet loom. At the same time, the valve also prevents water in the water tank 17 from flowing out through the water inlet pipe 24 when it is not in use, thus ensuring a stable water level in the water tank 17.

[0052] It should be noted that this utility model is a multi-arm shedding device for a water jet loom. The fabric body 16 first passes through the feed roller 3, which guides and initially conveys it to enter the subsequent stages at a suitable angle and position; then it passes through the rubber roller, where the rubber layer 9 adsorbs impurities on the fabric surface for cleaning, and the movement of the fabric drives the rubber roller to rotate; then it passes through the first guide roller 4 and the second guide roller 5 in sequence to ensure that the fabric is flat and passes through the device smoothly.

[0053] When it is necessary to adjust the horizontal position of the support plate 6, since the slide rod 11 is slidably connected to the support rod 10, and the slide sleeve 12 is slidably connected to the slide rod 11 and connected to the support plate 6, the horizontal position can be adjusted by changing the position of the slide sleeve 12 on the slide rod 11. The spring 13 connected to one side of the support frame 2 at one end of the slide rod 11 deforms when the slide rod 11 is slid by an external force, absorbing the impact energy. After the external force disappears, the slide rod 11 is pushed back to its original position or close to its original position by the elastic restoring force. When it is necessary to adjust the position of the support plate 6 and the rubber roller assembly, first loosen the bolt 15, slide the slide sleeve 12 to drive the support plate 6 and the rubber roller assembly to the appropriate position, and then thread the bolt 15 through the threaded through hole on the slide sleeve 12 and thread it to the corresponding threaded hole 14 on the slide rod 11 and tighten it to fix the position of the slide sleeve 12, the support plate 6 and the rubber roller assembly.

[0054] Water tank 17 stores water. The water pump 18 on the inner wall of the bottom of the machine box 1 is started. The water pump 18 draws water from the water tank 17 through the first water pipe 19 and then delivers the water to the nozzle 21 through the second water pipe 20. The nozzle 21 sprays water out in a certain shape and pressure for cleaning and to assist the weft insertion work of the fabric. When the water level in the water tank 17 is lower than the required water level, the valve on the water supply pipe 24 is opened and the external water source is injected into the water tank 17 through the water supply pipe 24. After the water level reaches the appropriate height, the valve is closed. The water sprayed out by the nozzle 21 flows into the water tank 17 through the water inlet 22 on the top of the machine box 1 and the water inlet on the top of the water tank 17. The filter screen 23 in the water inlet intercepts impurities in the water to prevent impurities from entering the water tank 17 and damaging the water pump 18 and nozzle 21 and other components.
