Abstract
Description
Technical Field
[0001] This invention belongs to the field of warp knitting machine technology, specifically a high-speed single-sided warp knitting machine. Background Technology
[0002] Warp knitting is a process where one or more groups of parallel yarns are simultaneously looped onto all the working needles in the warp direction to form a knitted fabric. The machine that performs this type of knitting is called a warp knitting machine. The main loop-forming components of a warp knitting machine include knitting needles, guide needles, sinkers, and pressure plates (for crochet machines). The knitting needles are arranged in rows on the needle bed and move with it. The guide needles are mounted on a guide bar to form a guide bar. The warp yarns pass through the eyelets of the guide needles and move with the guide bar, wrapping around the needles. Through the coordinated movement of the knitting needles, sinkers, and other loop-forming components, the fabric is woven. In a warp knitting machine, the guide bar is a crucial component in the loop-forming process. On warp knitting machines with relatively small widths, the guide bar drive, with its spring return mechanism, ensures the correct needle position.
[0003] With the advancement of technology and the improvement of people's living standards, demands are constantly changing and increasing. Currently, the market offers warp knitting machines with needle counts of 18, 24, 28, and 32. The needle count directly affects the performance of the knitting machine. A lower needle count results in a lower density and a narrower fabric width. Conversely, a higher needle count results in a higher density and a wider fabric width.
[0004] During the weaving process, fiber debris generated during yarn movement, as well as volatile chemicals such as antistatic additives added for preservation, are released into the surrounding processing area. These harmful components can pollute the processing environment, endanger the health of processing personnel, and the accumulation of these debris and impurities may also affect the normal operation of the single-sided warp knitting machine.
[0005] Therefore, existing high-speed single-sided warp knitting machines cannot meet the needs of actual use, so there is an urgent need for improved technologies to solve the above problems. Summary of the Invention
[0006] To overcome the shortcomings of existing technologies and solve the aforementioned technical problems, this invention proposes a high-speed single-sided warp knitting machine.
[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention proposes a high-speed single-sided warp knitting machine, including a machine base, and a warp feeding mechanism, a knitting mechanism, a pull-and-wind mechanism, a transmission mechanism, a control mechanism and an auxiliary purification mechanism mounted on the machine base. The auxiliary purification mechanism includes a purification box, which is set on the top of the machine base and located on both sides of the knitting mechanism. Ventilation holes are evenly arranged on the surfaces of the purification chamber that are close to each other. A sealing cover is provided on the outer surface of the purification chamber outside the ventilation holes. A purification belt is provided in the purification chamber inside the purification chamber. The purification belt is arranged in a ring and is provided with a filter cloth structure. It passes around the active roller that is rotated at the top of the purification chamber and the driven roller that is provided at the bottom of the purification chamber. The area enclosed by the purification belt is the air intake zone. Air inlets are evenly arranged on the side wall of the purification belt at the locations corresponding to the ventilation holes. An air extraction pipe is provided at the bottom of the purification box, and the air extraction pipe is connected to the air intake end of an external air pump device.
[0008] Preferably, the purification belt has a double-layer structure consisting of an inner purification layer and an outer purification layer, with the area between the inner and outer purification layers forming a purification gap, which is filled with absorbent particles made of activated carbon.
[0009] Preferably, a partition is uniformly arranged inside the purification gap, which divides the internal area of the purification gap into a purification zone and an adjustment zone. The purification zone and the adjustment zone are distributed alternately, and the activated carbon particles are concentrated in the purification zone.
[0010] Preferably, the inner purification layer corresponding to the adjustment zone is a filter cloth structure made of elastic material, the outer purification layer is a rubber membrane structure, the air inlet is located at the adjustment zone, and the air inlet is not connected to the interior of the adjustment zone; the inner and outer purification layers corresponding to the purification zone are filter cloth structures made of non-elastic material.
[0011] Preferably, an annular connecting pipe is provided inside the purification gap. The connecting pipe passes through the interior of each purification zone, adjustment zone and air inlet in sequence. The connecting pipe is a flexible metal tube. The side wall of the connecting pipe is provided with connection holes at corresponding positions inside each purification zone and adjustment zone.
[0012] Preferably, the two ends of the driven roller are connected to the adjustment block provided at the bottom of the purification chamber. The adjustment block is slidably embedded in the groove at the bottom of the purification chamber and is connected to the first telescopic device inside the groove.
[0013] Preferably, the two ends of the suction pipe located inside the purification chamber are connected to the adjustment blocks on both sides respectively. The adjustment blocks are hollow to form a transmission chamber. The outer surface of the driven roller is uniformly provided with collection holes, which communicate with the hollow part inside the driven roller. Both the driven roller and the suction pipe are connected to the inside of the transmission chamber.
[0014] Preferably, a squeezing plate is provided on the side wall of the purification chamber opposite the vent hole. The squeezing plate is connected to the output end of the second telescopic device provided on the inner wall of the purification chamber. The air inlet area is located in the area between the squeezing plate and the vent hole.
[0015] Preferably, an extrusion block is provided on the surface of the extrusion plate at the location corresponding to the air inlet. Both the extrusion block and the extrusion plate are made of conductive metal, and the extrusion plate is connected to a grounding wire.
[0016] The beneficial effects of this invention are as follows: The high-speed single-sided warp knitting machine of this invention arranges the purification boxes in the auxiliary purification mechanism on both sides of the machine base. Activating the external air pump causes the exhaust pipe to draw air into the purification chamber, creating a negative pressure at the bottom of the chamber. Debris and impurities generated in the processing area where the knitting mechanism is located flow with the air towards the purification box, then pass through the vents and into the purification chamber. Subsequently, due to the negative pressure, the air flows downwards from the inside out through the annular purification belt, passing through the filter cloth structure on the belt and separating the debris and impurities, leaving them inside the air intake area. The air is then drawn in by the exhaust pipe at the bottom and returns to the processing workshop through the air pump's outlet. This air circulation enriches the air intake area surrounded by the annular purification belt, improving the air quality inside the processing workshop and protecting the health of the processing personnel.

Detailed Implementation
[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0021] Example 1: As shown in the attached diagram of the instruction manual. Figures 1-6 As shown, a high-speed single-sided warp knitting machine includes a base 1, and a warp feeding mechanism, a knitting mechanism, a pull-and-wind mechanism, a transmission mechanism, a control mechanism and an auxiliary purification mechanism mounted on the base 1. The auxiliary purification mechanism includes a purification box 2, which is located on the top of the base 1 and on both sides of the knitting mechanism. Ventilation holes 21 are evenly arranged on the surfaces of the purification box 2 that are close to each other. A purification belt 23 is arranged in the purification chamber 22 inside the purification box 2. The purification belt 23 is arranged in a ring and has a filter cloth structure. It passes around the active roller 221 arranged at the top of the purification chamber 22 and the driven roller 222 arranged at the bottom of the purification chamber 22. The active roller 221 is connected to the output end of the motor equipment installed on the inner wall of the purification chamber 22. The driven roller 222 is rotatably connected to the inner wall of the purification chamber 22. The area surrounded by the purification belt 23 is the air intake zone 231. Air inlets 232 are evenly arranged on the side wall of the purification belt 23 at the locations corresponding to the ventilation holes 21. An air extraction pipe 24 is provided at the bottom of the purification box 2. The air extraction pipe 24 extends to the outside through a flexible hose and is connected to the air intake end of an external air pump device.
[0022] Specific workflow: During the operation of the high-speed single-sided warp knitting machine, the take-up roller in the warp feeding mechanism is activated to release the yarn. Combined with the yarn frame, yarn guide, tensioner, and other structures, the yarn is stably fed to the knitting mechanism area located on the machine base 1. Because this application uses a high-speed model, the guide bar movement is driven by a precision cam or electronic traverse mechanism mounted on the machine base 1, achieving high-frequency, high-precision knitting processing. Meanwhile, the roller mechanism in the take-up and pull-out mechanism controls the pull speed to coordinate with the processing rhythm of the knitting mechanism, ensuring that the knitted fabric is smoothly and evenly pulled out of the knitting area and neatly wound into a roll. During the above process, the servo motor, hydraulic cylinder, and lead screw of the transmission mechanism provide power for the warp knitting operation. The PLC intelligent control system of the control mechanism precisely controls the above processing operations and, as needed, can also be combined with an electronic traverse device to precisely control the guide bar movement trajectory, achieving complex pattern knitting. During the above processing, fiber debris generated during yarn movement and volatile chemicals such as antistatic additives added for preservation are dispersed around the processing area. These harmful components will pollute the processing environment and endanger the health of processing personnel. Furthermore, the accumulation of these debris and impurities may also affect the normal operation of the single-sided warp knitting machine. Therefore, the purification box 2 in the auxiliary purification mechanism of this application is arranged on both sides of the machine base 1. The closed plate of the purification box 2 near the knitting mechanism is opened, so that the ventilation hole 21 is connected to the outside. The external air pump equipment is started, so that the air extraction pipe 24 draws air into the purification chamber 22, so that a negative pressure is formed at the bottom of the purification chamber 22. The debris and impurities generated in the processing area where the knitting mechanism is located flow with the air towards the direction of the purification box 2, and then flow into the purification chamber 22 through the ventilation hole 21. In the initial state, the air inlet 232 on the purification belt 23 is set to correspond to the air vent 21. This facilitates the guidance of air flowing in from the outside to pass directly through the air inlet 232 into the air intake area 231 surrounded by the purification belt 23, thereby improving the efficiency of air flowing into the purification chamber 22 to participate in filtration and purification. Subsequently, due to the negative pressure, air penetrates the annular purification belt 23 from the inside out, passes through the filter cloth structure on the purification belt 23, and separates debris and impurities, leaving them inside the air intake area 231. Then, the air is drawn in by the bottom exhaust pipe 24 and returns to the processing workshop through the air outlet of the air pump. In this air circulation, the debris and impurities generated during the warp knitting process are enriched in the air intake area 231 surrounded by the annular purification belt 23, thereby improving the air quality inside the processing workshop and protecting the health of the processing personnel. Furthermore, the timing control starts the motor corresponding to the active roller 221, driving it as shown in the attached diagram. Figure 2The active roller 221 drives the purification belt 23 to rotate counterclockwise, causing the air inlet 232 on the purification belt 23 to move upward and be offset from the vent 21. The portion of the purification belt 23 that was originally located at the bottom of the purification chamber 22 and actively performs air purification functions moves to a position corresponding to the vent 21. Air flowing in from the outside passes through the vent 21, penetrates this portion of the purification belt 23, and flows into the air intake zone 231. This causes a reverse flushing effect on this portion of the purification belt 23, carrying away the accumulated and adhered debris and impurities on its inner wall, loosening them and detaching them from the inner wall of the purification belt 23. This keeps the debris loose in the air intake zone 231, preventing it from becoming sluggish. Debris and impurities adhere tightly to and accumulate in localized areas on the inner surface of the purification belt 23, affecting the overall passability of the purification belt 23. Therefore, by rotating the purification belt 23 slowly at regular intervals, all parts of the purification belt 23 are flushed and cleaned by the air vent 21, ensuring the overall passability of the purification belt 23. However, it is worth noting that when the purification belt 23 rotates counterclockwise to the area near the bottom of the air inlet 232, it needs to be stopped and its reverse rotation controlled. Therefore, the rotation of the purification belt 23 is not a full turn; it can be controlled to a half-turn range to prevent the air inlet 232 from rotating towards the bottom of the purification chamber 22, causing the collected debris and impurities inside to flow out. After working for a period of time, the purification box 2 can be opened to collect and clean the accumulated debris and impurities inside, and then empty them into the outside for recycling to ensure the normal operation of the purification box 2.
[0023] Example 2: Based on Example 1, the purification belt 23 has a double-layer structure and consists of an inner purification layer 233 and an outer purification layer 234. The area between the inner purification layer 233 and the outer purification layer 234 is a purification gap 235, and the purification gap 235 is filled with absorbent particles made of activated carbon.
[0024] Specific workflow: Based on the specific workflow in Example 1, the purification belt 23 is set to a double-layer structure. When the air brought into the air intake zone 231 needs to penetrate the purification belt 23 again, it needs to penetrate the inner purification layer 233, the absorbent particle layer in the purification gap 235, and the outer purification layer 234 in sequence. Such multiple purification can more thoroughly separate the debris and impurities in the air and improve the air circulation filtration effect. Furthermore, the filter pores of the filter cloth structure corresponding to the inner purification layer 233 can be set to be larger than those of the filter cloth structure corresponding to the outer purification layer 234. This reduces the resistance encountered by the air flowing into the purification gap 235, thus improving the airflow efficiency. On the other hand, for various pollutants in the air, larger particles are retained in the air intake zone 231 by the inner purification layer 233, while smaller particles are adsorbed and separated by the adsorbed particles as they flow along the gap between the adsorbed particles. Combined with the interception effect of the outer purification layer 234, these smaller particles are fully retained in the purification gap 235. In this way, the pollutants are dispersed to different corresponding positions according to their characteristics, ensuring the permeability of the inner purification layer 233 and the outer purification layer 234 while further improving the air purification efficiency.
[0025] Example 3: Based on Embodiment 2, a partition is uniformly arranged inside the purification gap 235, dividing the internal area of the purification gap 235 into a purification zone 236 and an adjustment zone 237. The purification zone 236 and the adjustment zone 237 are staggered, and the activated carbon particles are concentrated inside the purification zone 236. Regarding the specific distribution of the filter cloth structure on the purification belt 23, this application provides a possible implementation scheme. Specifically, the part of the inner purification layer 233 corresponding to the adjustment zone 237 is a filter cloth structure of elastic material, the outer purification layer 234 is an elastic rubber membrane structure, the air inlet 232 is located at the location of the adjustment zone 237, and the air inlet 232 does not communicate with the interior of the adjustment zone 237; the parts of the inner purification layer 233 and the outer purification layer 234 corresponding to the purification zone 236 are filter cloth structures of non-elastic material. The partition can be set as a rubber membrane structure, and an annular connecting pipe 238 is set inside the purification gap 235. The connecting pipe 238 passes through the interior of each purification zone 236, adjustment zone 237 and air inlet 232 in sequence, and is fixed to each penetrating partition. The connecting pipe 238 is a metal flexible tube structure. The side wall of the connecting pipe 238 is provided with corresponding parts inside each purification zone 236 and adjustment zone 237. In this way, air exchange can be carried out between different purification zones 236 and adjustment zones 237 through the connecting pipe 238. In order to avoid the loss of absorbed particles, the aperture of the connecting hole 239 can be set to be smaller than the particle size of the absorbed particles, or a filter screen can be set inside the connecting hole 239 to prevent the absorbed particles from penetrating inward. Specific workflow: Based on the specific workflow in Example 1, to avoid the uneven distribution of purification particles and their impact on throughput when the purification belt 23 rotates around the active roller 221 and driven roller 222 under the drive of the active roller 221, causing the purification particles to flow and concentrate at the bottom of the purification gap 235 due to gravity, resulting in uneven particle distribution; therefore, the internal area of the purification gap 235 is divided into multiple intersecting purification zones 236 and adjustment zones 237 by a partition layer. The absorbed particles are located in the purification zone 236 and are evenly distributed to various positions in the purification gap 235, making it difficult for them to accumulate locally. Furthermore, during air purification, outside air flows into the air intake zone 231 and flows downward. When it penetrates the purification belt 23 from the inside out, some air flows into the purification zone 236, and then sequentially penetrates the inner purification layer 233, the gap between purification particles, and the outer purification layer 234, finally flowing to the bottom of the purification chamber 22. Some airflow passes through the inner purification layer 233 corresponding to the adjustment zone 237 and flows into the interior of the adjustment zone 237. Because the outer purification layer 234 corresponding to the adjustment zone 237 is made of elastic rubber membrane material, it cannot be breathed. After the flow is obstructed, the air accumulates inside the adjustment zone 237, causing the adjustment zone 237 to expand. Then, the air flows to the interior of the adjacent purification zone 236 through the connecting hole 239 on the connected pipe 238 as the transmission path. This causes the absorbent particles inside the purification zone 236 to be impacted from multiple directions, maintaining the dispersed and breathable state of the absorbent particles while achieving full purification of the air. Furthermore, when the active roller 221 drives the purification belt 23 to rotate, when the purification zone 236 undergoes a large-scale bending deformation after passing the top active roller 221, the impact vibration on the internally accumulated absorbent particles causes some of the absorbent particles that may have accumulated due to adhering impurities to be impacted and dispersed, thereby ensuring that the absorbent particles inside the purification zone 236 remain in a dispersed conveying state, thus guaranteeing the overall passability of the purification belt 23.
[0026] Example 4: Based on Embodiment 3, the two ends of the driven roller 222 are connected to the adjustment blocks 25 at the bottom of the purification chamber 22. The adjustment blocks 25 are slidably embedded in the groove at the bottom of the purification chamber 22 and connected to the first telescopic device 251 inside the groove. The two ends of the exhaust pipe 24 located inside the purification chamber 22 are connected to the adjustment blocks 25 on both sides respectively. The hollow interior of the adjustment blocks 25 forms a transmission chamber 252. The outer surface of the driven roller 222 is uniformly provided with collection holes 223, which communicate with the hollow interior of the driven roller 222. Both the driven roller 222 and the exhaust pipe 24 communicate with the interior of the transmission chamber 252. The connecting pipe 238 is made of metal flexible hose, and the part of the connecting pipe 238 located inside the purification zone 236 is made of corrugated flexible hose with a pleated structure evenly distributed on the surface. Specific workflow: Based on the specific workflow in Embodiment 3, by controlling the first telescopic device 251, the adjusting block 25 is driven to move vertically along the slide groove, so that the driven roller 222 is adjusted in the vertical direction. This can adjust the tension of the entire purification belt 23, so that the adjustment area 237, which is expanded by air, is in a taut state, thereby compressing the air flowing into the interior and accelerating its flow to the adjacent purification area 236 along the connected pipe 238, thereby improving the air purification efficiency. During this process, the corrugated structure of the connecting pipe 238 inside the purification zone 236 deforms, causing the contacting absorbent particles to flow to each other; and as the first telescopic device 251 drives the adjusting block 25 to move vertically back and forth, the entire purification belt 23 continuously switches between a taut state and a relaxed state. The size of the internal space of each purification zone 236 and the adjusting zone 237 also changes due to the switching between the taut and relaxed states. This causes changes in the air pressure of each purification zone 236 and the adjusting zone 237, which in turn causes the airflow to flow and impact each other along the adjacent purification zones 236 and the adjusting zone 237 with the connecting pipe 238 as the path, ensuring that the flowing air has sufficient contact with the absorbent particles, thereby ensuring the passability of the entire purification belt 23. Furthermore, the driven roller 222 has a tubular structure, so that for large particles of debris collected inside the air inlet zone 231, the control valve at the end of the driven roller 222 can be opened at regular intervals, so that the driven roller 222 is connected to the inside of the suction pipe 24 through the transmission chamber 252. A filter screen is installed inside the transmission chamber 252, so that the suction effect is applied to the driven roller 222 through the transmission chamber 252. In this way, the debris accumulated inside the air inlet zone 231 is sucked into the driven roller 222 and then concentrated inside the transmission chamber 252, avoiding the concentration of large particles of debris from affecting the permeability of the purification inner layer 233.
[0027] Example 5: Based on Embodiment 4, a compression plate 26 is provided on the side wall of the purification chamber 22 opposite to the vent 21. The compression plate 26 is connected to the output end of the second telescopic device provided on the inner wall of the purification chamber 22. The air inlet area 231 is located in the area between the compression plate 26 and the vent 21. The outer surfaces on both sides of the purification belt 23 slide in contact with the inner wall surface of the purification box 2, which can prevent the air in the internal air inlet area 231 from seeping out through the gap between the purification belt 23 and the inner wall of the purification box 2, and guide the air inside the air inlet area 231 to seep out downward under pressure. An extrusion block 261 is provided on the surface of the extrusion plate 26 at the location corresponding to the air inlet 232. Both the extrusion block 261 and the extrusion plate 26 are made of conductive metal, and the extrusion plate 26 is connected to the grounding wire. Specific workflow: Based on the specific workflow in Example 4, as air continuously flows into the driven zone, the air pressure inside the intake zone 231 increases, causing the annular purification belt 23 to expand upward. At this time, in order to improve the air purification efficiency, the active roller 221 can be controlled to drive the purification belt 23 to rotate, so that the air inlet 232 rotates to the side close to the extrusion plate 26. Then, the extrusion plate 26 is started to move laterally to extrude the purification belt 23, so that the purification belt 23 is deformed under pressure. The internal space of the intake zone 231 decreases and the air pressure increases, causing the air flowing into the intake zone 231 to accelerate through the purification belt 23 and flow to the bottom exhaust pipe 24, thereby improving the air purification efficiency. Furthermore, when the purification belt 23 rotates and moves the air inlet 232 to a position directly opposite the extrusion block 261, the extrusion plate 26 moves and causes the extrusion block 261 to embed into the air inlet 232, ensuring that the entire air intake area 231 is compressed in a relatively closed environment, causing the internal air to accelerate downward permeation and outflow; during this process, the extrusion block 261 contacts the connecting pipe 238 inside the air inlet 232. Because the connecting pipe 238, the extrusion block 261, and the extrusion plate 26 are all made of conductive metal, and the extrusion plate 26 can transfer the absorbed static electricity to the ground through the grounding wire, this can effectively reduce the overall electrostatic adsorption of the purification belt 23, thereby reducing the tight adhesion between impurities and debris and the purification belt 23, and ensuring the overall passability of the purification belt 23.
