Description

Technical Field

[0001] This application relates to the field of textile printing, dyeing and finishing equipment technology, and more specifically, to an antistatic solvent immersion device and operating method for warp-knitted short plush sofa fabric. Background Technology

[0002] Warp-knitted short-pile fabrics are widely used in sofas, car seats, and soft furnishings due to their soft feel, full pile, and gentle luster. However, due to their fiber characteristics and weaving structure, these fabrics are prone to generating static electricity during use, leading to dust attraction and static shocks, which severely impacts the user experience. A search revealed an existing patent (publication number: CN113957647B) that discloses a functional fabric impregnation and finishing device. The device includes a finishing tank with fabric inlet and outlet ports at both ends, and corresponding guide rollers for guiding the fabric in and out. Several sets of series-connected stirring guide roller units are arranged within the finishing tank. Each stirring guide roller unit includes two stirring guide rollers arranged at different heights. Guide stirring plates with openings corresponding to the rotation direction are fixed at equal intervals on each stirring guide roller. The angle between the guide stirring plates and the stirring guide rollers is acute, and the guide stirring plates are relatively thin and have a certain degree of elasticity. The device includes guide rollers that stir and filter the finishing liquid, maintaining the finishing liquid in a slightly agitated state during the impregnation and finishing process of the fabric, while also effectively recovering floating lint and impurities. In the process of developing this application, the inventors discovered the following problems with the existing technology: Existing immersion devices do not have an automatic structure for handling loose fibers. The shed fibers float on the solvent surface or are suspended in the solvent, and are easy to re-adhere to the fabric surface, forming spots or clogging the subsequent rollers, affecting the finishing effect. Therefore, in response to the aforementioned technical problems, an antistatic solvent immersion device and operating method for warp-knitted short plush sofa fabric are proposed. Summary of the Invention

[0004] An antistatic solvent immersion device for warp-knitted short plush sofa fabric includes a solvent immersion device body and a recovery filter box.

[0007] Preferably, both the immersion zone and the circulation zone are rotatably connected by multiple sets of rubber-coated anti-winding immersion guide rollers arranged in an "S" shape with alternating vertical alignment via anti-loosening bearing seats. The inner walls on both sides of the solvent immersion device body are provided with overflow ports that communicate with the floating hair collection box. An ultrasonic vibration plate is fixedly connected to the bottom of the solvent immersion device body, and the ultrasonic vibration plate is equipped with a frequency converter.

[0008] Preferably, one side of the hair removal device is fixedly connected to an IP65-rated waterproof and dustproof scraper drive motor via a bracket, and a drive bevel gear is fixedly sleeved on the output shaft of the scraper drive motor via a shaft key. Inside the hair removal device, a movable drive screw with a telescopic dustproof and waterproof protective cover is rotatably connected via a bearing seat.

[0009] Preferably, a driven bevel gear that meshes with the driving bevel gear is fixedly sleeved on the outer side of one end of the movable drive screw. A closed dustproof cover is provided on the outer side of the two sets of bevel gears. A movable slider is threadedly connected to the outer side of the movable drive screw through an anti-loosening nut. The movable slider is slidably sleeved on the outer side of the slide rod guide structure. A silicone lint scraper is fixedly connected to the bottom end of the movable slider through a height and angle adjustment bracket.

[0010] Preferably, the height of the floating scraper is flush with the overflow port, and a liquid delivery pipe with a detachable filter head is fixedly inserted into the bottom of the solution guide box, and one end of the liquid delivery pipe is fixedly inserted into the recovery filter box through a sealing joint.

[0011] Preferably, the top of the recycling filter box is slidably inserted with a top cover via a sealing strip, and the bottom of the top cover is connected with a filter screen cylinder via a thread. A partition plate is fixedly connected inside the recycling filter box via a sealing ring, and the filter screen cylinder is slidably inserted into the partition plate. The partition plate divides the recycling filter box into a filtration zone and a clear liquid zone.

[0012] Preferably, a sealing ring is fixedly sleeved at the connection between the filter cylinder and the partition plate. A water pumping pipe and a water delivery pipe are fixedly connected to both ends of the filter circulation pump, respectively. The water pumping pipe is inserted into the lower part of the partition plate, and the water delivery pipe is inserted into the circulation area. A diffuser nozzle with multiple nozzles arranged in a ring is fixedly connected to the top end of the water delivery pipe. A side suction port is fixedly inserted into one side of the diffuser nozzle, and an air pipe is fixedly inserted into the side suction port.

[0013] Preferably, the operating method of the antistatic solvent immersion device for warp-knitted short-pile sofa fabric includes the following steps: Step 1: Add antistatic solvent into the main body of the solvent immersion device, adjust the liquid level to the preset height based on the feedback data of the electronic liquid level gauge, start the filter circulation pump to circulate the solvent for 5-10 minutes, and at the same time start the ultrasonic vibration plate and adjust it to the preset frequency. Step 2: The warp-knitted short plush sofa fabric to be processed is guided by the inlet and outlet guide rollers connected to the inlet guide frame at a speed of 5-20m / min and enters the main body of the solvent immersion device from the inlet and outlet. During the fabric conveying process, the anti-deviation guard of the guide frame prevents deviation. Step 3: The warp-knitted short plush sofa fabric first enters the immersion area and is fully immersed for 1-5 minutes under the S-shaped guidance of multiple sets of immersion guide rollers. The ultrasonic vibration plate vibrates the fabric to allow the antistatic solvent to fully penetrate. Step 4: The warp-knitted short plush sofa fabric enters the circulation zone through the connecting hole of the middle partition for a second soaking of 0.5-2 minutes. The circulation zone continuously replenishes the filtered fresh solvent to ensure the soaking effect. After soaking, the fabric leaves the main body of the solvent immersion device through the inlet and outlet ports under the guidance of the inlet and outlet guide rollers connected to the outlet guide frame. Step 5: During the soaking process, the floating hairs generated float on the surface of the solution. The scraper drive motor drives the floating hair scraper to reciprocate in a linear motion. Under the scraping action of the scraper, the floating hairs enter the floating hair collection box through the overflow port and are discharged into the recovery filter box through the miscellaneous liquid delivery pipe from the solution guide box. After entering the recovery filter box, the solution containing floating hairs is filtered by the filter screen and then sent back to the circulation area of ​​the solvent immersion device by the filter circulation pump through the diffusion nozzle, realizing the recycling of the solvent. Step Six: During equipment operation, regularly clean the floating lint on the filter screen cylinder. If abnormalities such as fabric entanglement on the guide roller or pipe blockage occur, stop the machine immediately for handling. After the equipment is used, recover the solvent through the drain port, clean the floating lint and impurities inside the device, and add grease to the transmission components.

[0014] The technical effects and advantages of this application are as follows: 1. Compared with existing technologies, the antistatic solvent immersion device and operation method for warp-knitted short plush sofa fabric, by setting an overflow port and a circulating filtration system, can scrape off floating hairs on the liquid surface in real time, preventing the floating hairs from adhering to the fabric again, ensuring the cleanliness of the fabric surface, and realizing dynamic removal of floating hairs on the liquid surface. During the soaking process, the floating hairs generated float on the top of the solution. The scraper drive motor drives the active straight bevel gear to rotate. During the rotation of the active straight bevel gear, it drives the moving drive screw to rotate through the driven straight bevel gear. During the rotation of the moving drive screw, it drives the moving slider and the floating hair scraper at its bottom to move horizontally. During the movement, the floating hair scraper scrapes the floating hairs on the solution surface into the overflow port. The solution with floating hairs enters the floating hair collection box through the overflow port, and is discharged into the recovery filtration box through the impurity liquid delivery pipe at the solution guide box.

[0015] 2. Compared with existing technologies, the antistatic solvent immersion device and operation method for warp-knitted short-pile sofa fabric adopts an ultrasonic vibration component. Utilizing the cavitation effect, it breaks down the surface tension of the fabric, allowing the antistatic solvent to quickly penetrate to the root of the short pile, improving finishing uniformity and effect. This solves the problem of difficult penetration caused by the surface pile covering the short-pile fabric. Under the action of multiple sets of immersion guide rollers, the fabric is fully immersed in the immersion zone. The warp-knitted short-pile sofa fabric enters the circulation zone through the connecting hole of the partition plate for secondary immersion. After immersion, guided by the inlet and outlet guide rollers connected to the outlet guide frame, it leaves the main body of the solvent immersion device through the inlet and outlet ports. During the immersion process, the ultrasonic vibration plate utilizes the cavitation effect to break down the surface tension of the fabric, allowing the antistatic solvent to quickly penetrate to the root of the short pile.

Both ends of the solvent immersion device body 1 are provided with inlet and outlet ports 13 adapted to the width of the fabric. The outer sides of the two sets of inlet and outlet ports 13 are respectively fixedly connected to an inlet guide frame 11 with anti-deviation baffle and an outlet guide frame 12. The recovery filter box 3 is fixedly connected to the side of the solvent immersion device body 1 near the inlet guide frame 11 by a flange seal. The solvent immersion device 1 has a floating lint scraping device 4 fixedly connected to its top, and floating lint collection boxes 2 fixedly connected to both sides of the solvent immersion device 1. The floating lint collection box 2 is fixedly connected to an inclined solution guide box 21 through a sealing joint at the end near the recovery filter box 3. The warp-knitted short plush sofa fabric to be processed enters the solvent immersion device 1 through the inlet / outlet port 13. The inlet guide frame 11 side is the inlet end, and the outlet guide frame 12 side is the outlet end. Tension adjustment mechanisms can be set at the inlet and outlet ends respectively. By adjusting the tension, the fabric tension is kept between 5-10N to avoid the fabric from being too tight and causing the lint to flatten. The tension adjustment mechanism is a common existing technology, and its specific structural principle will not be elaborated here. The solution with floating lint enters the floating lint collection box 2 and is discharged into the recovery filter box 3 through the solution guide box 21 for filtration.

The bottom end of the partition plate 15 has a connecting hole 151 with a flared anti-clogging filter screen that connects the immersion zone 17 and the circulation zone 16. An electronic level gauge 7 is fixedly connected to the inner wall of the circulation zone 16. The fabric is immersed in the immersion zone 17 and then immersed a second time in the circulation zone 16. The solution replenished in the circulation zone 16 can enter the immersion zone 17 through the connecting hole 151. The water levels in the immersion zone 17 and the circulation zone 16 are always the same. The solution height can be detected in real time by the electronic level gauge 7. The detection data is fed back to the filter circulation pump 5, and the filter circulation pump 5 is driven to replenish the solution according to the feedback signal.

[0022] Reference Figure 3 and Figure 4As shown, both the impregnation zone 17 and the circulation zone 16 are rotatably connected by multiple sets of rubber-coated anti-winding impregnation guide rollers 18 arranged in an "S" shape with anti-loosening bearing seats.

The bottom end of the solvent impregnation device body 1 is fixedly connected to an ultrasonic vibration plate 6, which is equipped with a frequency converter. The impregnation guide rollers 18 allow the warp-knitted short-pile sofa fabric to be in the solution for a longer time, and the "S" shape arrangement ensures that the fabric is impregnated in a wrinkle-free and low-tension state, protecting the style of the pile and facilitating a uniform and thorough impregnation. During the impregnation process, the ultrasonic vibration plate 6 uses the cavitation effect to break the surface tension of the fabric, allowing the antistatic solvent to quickly penetrate to the root of the short pile, improving the uniformity and effect of the finishing. The water level in the impregnation zone 17 and the circulation zone 16 is maintained at the same level as the bottom end of the overflow port 19.

A movable drive screw 42 with a telescopic dustproof and waterproof protective cover is rotatably connected inside the lint removal device 4 via a bearing seat; the drive bevel gear 411 is driven by the scraper drive motor 41 to rotate inside the lint removal device 4.

[0024] Reference Figure 6 As shown, a driven bevel gear 43 that meshes with the driving bevel gear 411 is fixedly sleeved on the outer side of one end of the movable drive screw 42. A closed dustproof cover is provided on the outer side of the two sets of bevel gears. A movable slider 44 is threadedly connected to the outer side of the movable drive screw 42 through an anti-loosening nut. The movable slider 44 is slidably sleeved on the outer side of the guide structure of the slider rod, and a silicone material scraper 441 is fixedly connected to the bottom end of the movable slider 44 through a height and angle adjustment bracket. During the rotation of the driving bevel gear 411, the movable drive screw 42 is driven to rotate through the driven bevel gear 43. During the rotation of the movable drive screw 42, the movable slider 44 and the scraper 441 at its bottom end are moved horizontally. During the movement, the scraper 441 scrapes the floating hair on the surface of the solution into the overflow port 19.

[0025] Reference Figure 3 , Figure 4 and Figure 7As shown, the height of the lint scraper 441 is flush with the overflow port 19. A liquid delivery pipe 211 with a detachable filter head is fixedly inserted into the bottom of the solution guide box 21. One end of the liquid delivery pipe 211 is fixedly inserted into the recovery filter box 3 through a sealing joint. A one-way valve is installed on the liquid delivery pipe 211 to prevent solution backflow. The solution with lint enters the lint collection box 2 through the overflow port 19 and is discharged into the recovery filter box 3 through the liquid delivery pipe 211 from the solution guide box 21.

[0026] Reference Figure 7 and Figure 8 As shown, the top of the recycling filter box 3 is slidably connected to the top cover 31 by a sealing strip, and the bottom of the top cover 31 is connected to the filter screen cylinder 311 by a thread.

[0027] Reference Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, a sealing ring 312 is fixedly fitted at the connection between the filter cylinder 311 and the partition plate 32. A water suction pipe 51 and a water delivery pipe 52 are fixedly connected to both ends of the filter circulation pump 5, respectively. The water suction pipe 51 is inserted below the partition plate 32, and the water delivery pipe 52 is inserted into the circulation zone 16. A diffuser nozzle 53 with multiple nozzles arranged in a ring is fixedly connected to the top of the water delivery pipe 52. A side suction port 531 is fixedly inserted into one side of the diffuser nozzle 53, and an air pipe 532 is fixedly inserted into the side suction port 531.

The solution is filtered, and the floating hairs in the solution are trapped in the filter screen cylinder 311. The filter circulation pump 5 draws away the filtered clear liquid through the water suction pipe 51 and pumps it into the circulation zone 16 through the water delivery pipe 52. During the liquid discharge process, the water delivery pipe 52 stirs the liquid in the circulation zone 16 under the action of the diffusion nozzle 53. The high-pressure gas is sent into the diffusion nozzle 53 through the side suction port 531 by the air pipe 532, thereby increasing the liquid discharge pressure of the diffusion nozzle 53 to complete the stirring effect. The control of the filter circulation pump 5 and the structure of the diffusion nozzle 53 and its connected side suction port 531 are existing mature technologies, and will not be described in detail here.

[0028] The operating method for using an antistatic solvent immersion device for warp-knitted short-pile sofa fabric includes the following steps: Step 1: Add antistatic solvent into the main body 1 of the solvent immersion device, adjust the liquid level to the preset height based on the feedback data of the electronic liquid level gauge 7, start the filter circulation pump 5 to circulate the solvent for 5-10 minutes, and at the same time start the ultrasonic vibration plate 6 and adjust it to the preset frequency. Step 2: The warp-knitted short plush sofa fabric to be processed is guided by the inlet and outlet guide rollers 121 connected to the inlet guide frame 11 at a speed of 5-20m / min and enters the main body 1 of the solvent immersion device through the inlet and outlet 13. During the fabric conveying process, the anti-deviation guard of the guide frame prevents deviation. Step 3: The warp-knitted short plush sofa fabric first enters the immersion zone 17 and is fully immersed in the immersion zone 17 for 1-5 minutes under the S-shaped guidance of multiple sets of immersion guide rollers 18. The ultrasonic vibration plate 6 vibrates the fabric to allow the antistatic solvent to fully penetrate. Step 4: The warp-knitted short plush sofa fabric enters the circulation zone 16 through the connecting hole 151 of the partition plate 15 for a second soaking of 0.5-2 minutes. The circulation zone 16 continuously replenishes the filtered fresh solvent to ensure the soaking effect. After soaking, under the guidance of the inlet and outlet guide rollers 121 connected to the outlet guide frame 12, it leaves the solvent immersion device body 1 through the inlet and outlet 13. Step 5: During the soaking process, the floating hairs generated float on the surface of the solution. The scraper drive motor 41 drives the floating hair scraper 441 to reciprocate linearly. Under the scraping action of the scraper, the floating hairs enter the floating hair collection box 2 through the overflow port 19, and are discharged into the recovery filter box 3 through the impurity liquid delivery pipe 211 from the solution guide box 21. After entering the recovery filter box 3, the solution with floating hairs is filtered by the filter screen cylinder 311 and then sent back to the circulation area 16 of the solvent immersion device body 1 by the filter circulation pump 5 through the diffusion nozzle 53, so as to realize the recycling of solvent. Step Six: During equipment operation, regularly clean the loose fibers on the filter cylinder 311. If abnormalities such as fabric entanglement on the guide roller or pipe blockage occur, stop the machine immediately for handling. After the equipment is used, recover the solvent through the drain port, clean the loose fibers and impurities inside the device, and add grease to the transmission components.

[0029] The working process of this application is as follows: First, the warp-knitted short plush sofa fabric to be processed enters the main body 1 of the solvent immersion device through the inlet / outlet port 13 under the guidance of the inlet / outlet guide rollers 121 connected to the inlet guide frame 11. The warp-knitted short plush sofa fabric first enters the immersion zone 17 and is fully immersed in the immersion zone 17 under the action of multiple sets of immersion guide rollers 18. The warp-knitted short plush sofa fabric enters the circulation zone 16 through the connecting hole 151 of the middle partition plate 15 for secondary immersion. After immersion, under the guidance of the inlet / outlet guide rollers 121 connected to the outlet guide frame 12, it leaves the main body 1 of the solvent immersion device through the inlet / outlet port 13. During the immersion process, the ultrasonic vibration plate 6 is used to destroy the surface tension of the fabric by utilizing the cavitation effect, so that the antistatic solvent can quickly penetrate to the root of the short plush, improving the uniformity and effect of the finishing. During the soaking process, the floating hair generated floats on the surface of the solution. The drive bevel gear 41 is driven by the scraper drive motor 41 to rotate. During the rotation of the drive bevel gear 411, the driven bevel gear 43 drives the moving drive screw 42 to rotate. During the rotation of the moving drive screw 42, the moving slider 44 and the floating hair scraper 441 at its bottom move horizontally. During the movement, the floating hair scraper 441 scrapes the floating hair on the surface of the solution into the overflow port 19. The solution with floating hair enters the floating hair collection box 2 through the overflow port 19 and is discharged into the recovery filter box 3 through the impurity liquid delivery pipe 211 from the solution guide box 21. The floating hairs in the solution are trapped in the filter screen cylinder 311. The solution height is detected in real time by the electronic level gauge 7. The detection data is fed back to the filter circulation pump 5, and the filter circulation pump 5 is driven to replenish the solution according to the feedback signal. The filter circulation pump 5 draws away the filtered clear liquid through the water suction pipe 51 and pumps it into the circulation zone 16 through the water delivery pipe 52. During the liquid discharge process, the water delivery pipe 52 stirs the liquid in the circulation zone 16 under the action of the diffusion nozzle 53.

10. A method for operating an antistatic solvent immersion device for warp-knitted short-pile sofa fabric, employing the antistatic solvent immersion device for warp-knitted short-pile sofa fabric as described in any one of claims 1-9, characterized in that: The operation method includes the following steps: Step 1: Add antistatic solvent into the main body (1) of the solvent immersion device, adjust the liquid level to the preset height through the feedback data of the electronic liquid level gauge (7), start the filter circulation pump (5) to circulate the solvent for 5-10 minutes, and at the same time start the ultrasonic vibration plate (6) to the preset frequency. Step 2: The warp-knitted short plush sofa fabric to be processed is guided by the inlet and outlet guide rollers (121) connected to the inlet guide frame (11) at a speed of 5-20m / min and enters the main body (1) of the solvent immersion device through the inlet and outlet (13). During the fabric conveying process, the guide frame anti-deviation guard prevents deviation. Step 3: The warp-knitted short plush sofa fabric first enters the immersion area (17) and is fully immersed in the immersion area (17) for 1-5 minutes under the S-shaped guidance of multiple immersion guide rollers (18). The ultrasonic vibration plate (6) vibrates the fabric to allow the antistatic solvent to fully penetrate. Step 4: The warp-knitted short plush sofa fabric enters the circulation zone (16) through the connecting hole (151) of the partition plate (15) for a second soaking of 0.5-2 minutes. The circulation zone (16) continuously replenishes the filtered fresh solvent to ensure the soaking effect. After the soaking is completed, the fabric leaves the main body (1) of the solvent immersion device through the inlet and outlet (13) under the guidance of the inlet and outlet guide rollers (121) connected to the outlet guide frame (12). Step 5: During the soaking process, the floating hairs generated float on the top of the solution. The scraper drive motor (41) drives the floating hair scraper (441) to make reciprocating linear motion. Under the scraping action of the scraper, the floating hairs enter the floating hair collection box (2) through the overflow port (19) and are discharged into the recovery filter box (3) through the miscellaneous liquid delivery pipe (211) at the solution guide box (21). The solution with floating hairs in the recovery filter box (3) is filtered by the filter screen cylinder (311) and then sent back to the circulation area (16) of the solvent immersion device body (1) by the filter circulation pump (5) through the diffusion nozzle (53) to realize the recycling of solvent. Step 6: During equipment operation, regularly clean the floating lint on the filter screen cylinder (311). If abnormalities such as fabric wrapping around the guide roller or pipe blockage occur, stop the machine immediately for treatment. After the equipment is used, recover the solvent through the drain port, clean the floating lint and impurities inside the device, and add grease to the transmission components.
