Technical Field
[0001] This application relates to the field of warp-knitted fabric processing, and in particular to a warp-knitted fabric processing and finishing device. Background Technology
[0002] Warp-knitted fabric finishing is a series of post-processing steps involving mechanical treatment, cleaning, shaping, and fabric function optimization after warp-knitted fabrics have been woven.

[0021] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".
[0022] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0023] Example 1 This application discloses a warp-knitted fabric processing and finishing device, which, based on a lint roller 401, a reduction motor 6, an electric push rod 8, a flat pressure roller 403, and a flat pressure table 404, achieves coordinated control of surface lint removal and shape shaping of warp-knitted fabrics. The specific steps are as follows: 1. The warp-knitted fabric layer 5 to be processed is introduced from the left side of the processing table 1 and sequentially passed around the lint roller 401 and each feed roller 3 to ensure that the fabric is in full contact with the lint-adhesive protrusions on the outside of the lint roller 401. The end of the fabric extends to the winding device connected to the right side of the processing table 1.
[0024] Combing and delinting control: Start the geared motor 6, which drives the first pulley 7 to rotate through the coupling. Since the first pulley 7 is coaxially fixed with the front end of the lint roller 401, it drives the lint roller 401 to rotate clockwise at a set speed of 15-30 r / min. The lint-adhesive protrusions are distributed in a ring array. During the rotation, they accurately adsorb lint, dust and other impurities on the fabric surface, achieving directional combing. Depending on the impurity content of the fabric, the variable frequency speed of the geared motor 6 can be adjusted. When there are more impurities, the speed can be increased to 25-30 r / min, and when there are fewer impurities, it can be maintained at 15-20 r / min to avoid excessive friction and damage to the fabric fibers.
[0025] 3. Simultaneously activate the electric push rod 8 at the top of the first frame 402. Adjust the push rod stroke according to the thickness of the warp-knitted fabric to drive the U-shaped groove seat at the bottom to move the flat pressure roller 403 vertically downward until the flat pressure roller 403 and the flat pressure table 404 below form a suitable pressure. The flat pressure roller 403 is rotatably connected through the U-shaped groove seat and rolls synchronously with the fabric during the fabric transfer process. The squeezing action between the roller surface and the flat pressure table 404 eliminates fabric wrinkles. If there are stubborn wrinkles in the fabric, the pressure can be increased to 0.5-0.8MPa in stages by the electric push rod 8. After 3-5 seconds, the initial pressure is restored to avoid long-term high pressure causing fabric deformation.
[0026] 4. The speed of the geared motor 6 is matched with the transmission speed of the feed roller 3 to ensure that the combing frequency of the lint roller 401 is adapted to the fabric movement speed. At the same time, the rolling speed of the flat roller 403 is synchronized with the fabric transmission, realizing continuous combing-flat pressing operation, effectively improving the lint removal rate and wrinkle elimination rate of the fabric surface after finishing.
[0027] Example 2 This application discloses a warp-knitted fabric processing and finishing device, which achieves adaptive adjustment of the transmission tension of warp-knitted fabrics of different specifications based on the elastic element 406, vertical groove 9, adjusting screw 4064 and tension roller 407. The specific steps are as follows: 1. Based on the material and elasticity coefficient of the fabric to be processed, preset the initial tension range. By observing the fabric transmission state, if the fabric is loose and drooping, it is determined that the tension is insufficient; if the fabric is stretched and deformed, it is determined that the tension is too high. The initial adjustment is made based on this.
[0028] 2. Rotate the adjusting screw 4064 inside the vertical groove 9. Since the slide block 4063 is threadedly connected to the adjusting screw 4064 and is sleeved outside the guide screw 4061, the rotational motion of the adjusting screw 4064 is converted into the vertical sliding motion of the slide block 4063. Rotating the adjusting screw 4064 clockwise causes the slide block 4063 to drive the tension roller 407 downward, increasing the fabric tension; rotating it counterclockwise causes the tension roller 407 to move upward, decreasing the tension, until the tension reaches the preset range.
[0029] 3. The buffer springs 4062 at the top and bottom of the guide screw 4061 play a dynamic buffering role. When there is a momentary tension fluctuation during the fabric transmission process (such as a slight change in the speed of the feed roller), the slide block 4063 slides along the guide screw 4061, and the buffer spring 4062 absorbs the tension peak by extension and contraction, preventing the fabric from being pulled apart or loosened due to momentary overload. For example, when the tension suddenly increases to 25N, the upper buffer spring is compressed to absorb the excess tension.
[0030] Adaptability verification: After adjustment, start the feed roller 3 for trial transmission and continuously observe whether wrinkles or stretch marks appear on the fabric surface. Monitor the tension value in real time by setting a tension sensor. If it deviates from the preset range, repeat step 2 for fine adjustment to reduce tension stability error and adapt to the continuous transmission requirements of different elastic fabrics.
[0031] Example 3 This application discloses a warp-knitted fabric processing and finishing device, which integrates the cleaning and dehydration of fabric surface stains based on a washing tank 10, a stirring motor 11, a dispensing pump 13, a spray pipe frame 408, and a squeezing roller 409. The specific steps are as follows: 1. Pour deionized water and neutral cleaning solution into the cleaning tank 10 at a ratio of 100:1 to 100:3. Start the stirring motor 11 and drive the stirring rod 12 to rotate at a speed of 60-120 r / min. Stir for 5-10 minutes to ensure that the cleaning solution is mixed evenly and avoid local high concentrations that may damage the fabric or low concentrations that may affect the cleaning effect.
[0032] 2. Start the infusion pump 13 to draw the mixed cleaning solution from the cleaning tank 10 through the first infusion tube and deliver it to the spray tube frame 408 through the second infusion tube. Adjust the flow rate of the infusion pump 13 to 5-15L / min to ensure that the cleaning solution forms a uniform mist spray through the spray holes of the spray tube frame 408 and fully covers the surface of the fabric during transmission. Control the spray pressure at 0.1-0.3MPa to ensure the stain removal effect while avoiding the fabric fibers from pilling due to high pressure spraying.
[0033] 3. Since the extrusion rollers 409 are meshed with the gear disk 14, and the second pulley 15 of one of the gear disks 14 is driven by the first pulley 7 via a belt, when the reduction motor 6 starts, it synchronously drives the two extrusion rollers 409 to rotate in opposite directions at a speed of 20-40 r / min (the upper roller rotates counterclockwise and the lower roller rotates clockwise). After the fabric is sprayed, it enters between the upper and lower pressed extrusion rollers 409. The extrusion action of the roller surface removes the cleaning liquid from the surface of the fabric, avoiding the residue of cleaning liquid that may cause the fabric to become moldy or increase the drying burden.
[0034] Example 4 This application discloses a warp-knitted fabric processing and finishing device, which achieves rapid drying and shape setting of warp-knitted fabrics based on a drying rack 410, an electric heating wire tube 412, an exhaust fan 16, and a metal mesh frame 411. The specific steps are as follows: 1. Based on the fabric material and moisture content, set the moisture content after squeezing and dehydration to approximately 15-20%, and set the heating temperature range of the heating wire tube 412 to 60-120℃. For polyester warp-knitted fabrics, use 80-120℃, and for nylon warp-knitted fabrics, use 60-90℃ to avoid fabric deformation or discoloration due to high temperatures. Set the wind speed level of the induced draft fan 16 to 1-3, corresponding to a wind speed of 2-5m / s. Select the higher setting when the moisture content is high and the lower setting when the moisture content is low.
[0035] 2. Start the heating element 412. After the temperature rises to the preset value and stabilizes, start the exhaust fan 16 to deliver cold air into the drying rack 410 through the air duct. The cold air is heated by the heating element 412 and converted into hot air. It forms a uniform airflow through the pore layer (with a pore diameter of 1-3mm) on the bottom wall of the metal mesh frame 411 and acts vertically on the fabric surface being transported below.
[0036] 3. Control the fabric conveying speed (0.5-2m / min) and drying time (10-30 seconds) to ensure that the hot air fully penetrates the fabric fibers. The metal mesh frame 411 plays a protective role, preventing the heating wire tube 412 from directly contacting the fabric and causing burns. At the same time, the continuous blowing of hot air can help the fabric maintain its flat shape, so that drying and shaping can be completed simultaneously.
[0037] 4. Temperature and humidity sensor modules are installed inside the drying rack 410 to monitor the temperature inside the drying chamber and the humidity at the fabric outlet in real time. If the humidity is higher than 5%, the temperature of the heating wire tube is automatically increased or the transmission speed is reduced. If the temperature exceeds the preset range, the power supply to the heating wire tube is automatically cut off to cool it down, ensuring stable drying quality.
[0038] In summary, the working principle design of this warp-knitted fabric processing and finishing device includes: 1) High-efficiency lint removal and cleaning design: The outer side of the lint roller is equipped with a ring array of lint-removing protrusions. Combined with the belt drive driven by the geared motor, it can accurately capture lint and dust on the fabric surface. The cleaning effect is better than that of traditional brushes. Moreover, the lint roller and the feed roller work together to feed the material without damaging the fabric fibers.
[0039] 2) Flexible tension adjustment: The tension roller achieves a buffering effect through the guide screw and the upper and lower buffer springs. With the adjustment screw in the vertical groove, the tension can be flexibly adjusted according to the fabric thickness and elasticity to avoid overstretching or understretching, and can be adapted to various specifications of warp-knitted fabrics.
[0040] 3) Precise cleaning and dehydration synergy: The cleaning tank is equipped with a stirring motor to achieve uniform mixing of the cleaning solution, and the infusion pump accurately delivers it to the spray tube frame for targeted spraying on the fabric surface. Combined with the upper and lower squeeze rollers, the water is squeezed and dehydrated simultaneously, reducing cleaning solution residue and preventing the fabric from becoming damp and moldy.
[0041] 4) Refined flat pressing and shaping: The electric push rod of the first frame drives the flat pressing roller to move up and down, and the flat pressing pressure can be adjusted. Together with the flat pressing table below, it effectively eliminates fabric wrinkles. The squeezing roller achieves synchronous reverse rotation through gear plate meshing and belt drive, further improving the flatness of the fabric.
[0042] 5) High-efficiency and uniform drying: The drying rack has built-in electric heating wire tubes, which, together with the exhaust fan and the air hole layer of the metal mesh frame, allow hot air to evenly cover the fabric surface, resulting in high drying efficiency. Furthermore, the electric heating wire tubes are located directly below the air duct, minimizing heat loss and reducing energy consumption.
