Abstract
Description
Technical Field
[0001] This utility model relates to the field of warp knitting machine filter cleaning technology, specifically a self-cleaning warp knitting machine for preventing filter clogging in warp knitting fabric preparation. Background Technology
[0002] A warp knitting machine uses one or more sets of parallel yarns fed into all the working needles of the machine in the warp direction to simultaneously form loops and create a knitted fabric. This method is called warp knitting, the fabric is called warp-knitted fabric, and the machine that performs this type of warp knitting is called a warp knitting machine. A filter screen is needed on a warp knitting machine to filter out dust or lint.
[0003] Chinese patent CN222043502U discloses a textile warp knitting machine with a lint removal mechanism, comprising: a warp knitting machine body, an exhaust fan movably connected to the left surface of the warp knitting machine body, an air duct fixedly connected to the output end of the exhaust fan, an air duct fixedly connected to the end of the air duct away from the exhaust fan, a filter screen fixedly connected to the front surface of the air duct, a first linear motor fixedly connected to the inner surface of the warp knitting machine body, and a scraper fixedly connected to the output end of the first linear motor. This patent uses the linear motor to drive the scraper to reciprocate, thereby scraping away dust and lint from the filter screen.
[0004] Although the existing technology uses a linear motor to move a scraper back and forth to remove dust and lint from the filter screen, the pressure exerted by the scraper on the filter screen during scraping causes some of the dust and lint to penetrate deeper into the filter screen pores. As the dust and lint gradually accumulate, they will still clog the filter screen. Utility Model Content
[0005] The purpose of this invention is to provide a self-cleaning warp knitting machine for preparing warp-knitted fabrics, which prevents filter screen clogging. By reciprocating the movement of the filter screen, the filter screen vibrates, thereby shaking off the dust on the filter screen and achieving the function of self-cleaning the filter screen, thus preventing dust and lint from clogging the filter screen holes.
[0006] To address the existing technical problems, this utility model provides a self-cleaning warp knitting machine for preparing warp-knitted fabrics, which includes a warp knitting machine body. A filter placement groove is provided on one side of the warp knitting machine body. A filter assembly for filtering dust is also provided in the warp knitting machine body. A collection assembly is also installed on the warp knitting machine body. The filter assembly includes a filter body that is slidably disposed in the filter placement groove. The filter assembly also includes a vibration assembly for vibrating the filter body.
[0007] Preferably, the vibration assembly includes two support frames that are symmetrical about the center position of the warp knitting machine body and fixed inside the warp knitting machine body. Each support frame has two second sleeves on the side near the filter body. The vibration assembly also includes a first spring disposed in the second sleeve. One end of the first spring is connected to the filter body, and the other end of the first spring is connected to the second sleeve.
[0008] Preferably, a first sleeve is provided on the support frame near the filter body, and a reciprocating transmission sleeve is also provided inside the first sleeve. A connecting rod is connected to the filter body, and a second spring is sleeved on the connecting rod. One end of the connecting rod is slidably disposed in the transmission sleeve. One end of the second spring is connected to the connecting rod, and the other end of the second spring is connected to the transmission sleeve. The vibration assembly also includes a drive mechanism for driving the transmission sleeve to reciprocate.
[0009] Preferably, the drive mechanism includes a crankshaft rotatably mounted in the support frame, a connecting shaft connected to the crankshaft, one end of the connecting shaft passing through the support frame and connected to a first pulley, and the drive mechanism further includes a transmission rod, one end of which is movably connected to the crankshaft, and the other end of which is movably connected to a transmission sleeve.
[0010] Preferably, the driving mechanism includes a rotary driving member, one end of which is connected to a second pulley, and the second pulley is connected to the first pulley via a belt.
[0011] Preferably, the collection component includes a first negative pressure fan fixed to the top of the warp knitting machine body. The air inlet of the first negative pressure fan is connected to an air intake, which is located on the side of the top of the warp knitting machine body near the filter placement slot. The air outlet of the first negative pressure fan is connected to a first pipe. A cavity is also provided on the side of the warp knitting machine body away from the filter placement slot, and one end of the first pipe extends into the cavity.
[0012] Preferably, the collection component includes a second negative pressure fan fixed inside the warp knitting machine body, the outlet of the second negative pressure fan is connected to a second pipe, one end of the second pipe is connected to a first pipe, and the inlet of the second negative pressure fan is located away from the filter placement slot.
[0013] Preferably, the collecting component further includes a collecting box that is slidably disposed in the internal cavity of the warp knitting machine.
[0014] The advantages of this utility model compared to the prior art are:
[0015] 1. This application achieves an automatic cleaning function for the filter screen by configuring a filter screen body and a vibration component. Specifically, the rotation of the crankshaft drives the transmission rod to move, which in turn drives the transmission sleeve to reciprocate. The reciprocating motion of the transmission sleeve causes the second spring to reciprocate and deform, which in turn causes the connecting rod to drive the filter screen body to vibrate. This vibration mechanism effectively shakes off dust and lint from the filter screen body, avoiding the problem that dust and lint may penetrate deep into the filter screen body and gradually cause blockage, which can occur with traditional scraper cleaning methods.
[0016] 2. To ensure effective removal of dust and lint, after the dust and lint on the filter body are shaken off, the first negative pressure fan and the second negative pressure fan are started simultaneously. The suction generated by the two fans works together to draw the dust and lint on both sides of the filter body into the collection box, thereby achieving centralized collection of dust and lint for subsequent unified processing.

[0026] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0027] Reference Figures 1-8 As shown, this utility model provides a self-cleaning warp knitting machine for preparing warp-knitted fabrics, which is designed to prevent filter clogging. It includes a warp knitting machine body 1, with a filter placement groove 11 on one side. The machine body 1 also includes a filter assembly 13 for filtering dust, and a collection assembly 12. The filter assembly 13 includes a filter body 131 slidably disposed in the filter placement groove 11. The assembly also includes a vibration assembly 132 for vibrating the filter body 131. The vibration assembly 132 vibrates the filter body 131 to shake off accumulated dust during the filtration process, preventing filter clogging.
[0028] When the warp knitting machine is working, dust is filtered through the filter body 131 in the filter placement slot 11. Over time, dust accumulates on the filter body 131. To keep the filter body 131 clear, the vibration component 132 is activated periodically to vibrate the filter body 131 and shake off the accumulated dust. The shaken-off dust is then collected by the collection component 12, preventing dust from re-entering the working environment. In this way, the warp knitting machine can keep the filter body 131 clear for a long time, improving the operating efficiency and reliability of the equipment.
[0029] refer to Figures 4-7As shown, the vibration assembly 132 includes two support frames 1321 that are symmetrical about the center of the warp knitting machine body 1 and fixed inside the warp knitting machine body 1. Each support frame 1321 has two second sleeves 1322 on the side near the filter body 131. The vibration assembly 132 also includes a first spring 13221 disposed in the second sleeve 1322. One end of the first spring 13221 is connected to the filter body 131, and the other end of the first spring 13221 is connected to the second sleeve 1322. The first spring 13221 not only provides elastic support for the filter body 131, but also realizes the vibration of the filter through its compression and release process.
[0030] A first sleeve 13211 is provided on the support frame 1321 near the filter body 131. Inside the first sleeve 13211, a reciprocating transmission sleeve 1326 is also provided. A connecting rod 1311 is connected to the filter body 131, and a second spring 1327 is sleeved on the connecting rod 1311. One end of the connecting rod 1311 is slidably disposed in the transmission sleeve 1326. One end of the second spring 1327 is connected to the connecting rod 1311, and the other end of the second spring 1327 is connected to the transmission sleeve 1326. The vibration assembly 132 also includes a drive mechanism for driving the transmission sleeve 1326 to reciprocate. When the transmission sleeve 1326 reciprocates under the action of the drive mechanism, the second spring 1327 is compressed and released accordingly, thereby further enhancing the vibration effect of the filter. This design improves the amplitude and frequency of vibration.
[0031] The drive mechanism includes a crankshaft 1323 rotatably mounted in a support frame 1321, a connecting shaft 13231 connected to the crankshaft 1323, one end of the connecting shaft 13231 passing through the support frame 1321 and connected to a first pulley 13232, the drive mechanism also includes a transmission rod 1325, one end of the transmission rod 1325 is movably connected to the crankshaft 1323, the other end of the transmission rod 1325 is movably connected to a transmission sleeve 1326, the drive mechanism includes a rotary drive component 1324, one end of the rotary drive component 1324 is connected to a second pulley 13241, the second pulley 13241 is connected to the first pulley 13232 via a belt.
[0032] The rotation of the crankshaft 1323 drives the transmission rod 1325 to move, which in turn drives the transmission sleeve 1326 to reciprocate. The reciprocating motion of the transmission sleeve 1326 causes the second spring 1327 to reciprocate and deform, which in turn causes the connecting rod 1311 to drive the filter body 131 to vibrate. This vibration mechanism effectively shakes off dust and lint from the filter body 131, avoiding the problem that dust and lint may penetrate deep into the filter body 131 and gradually cause blockage, which can occur with traditional scraper cleaning methods.
[0033] refer to Figure 8As shown, the collection assembly 12 includes a first negative pressure fan 121 fixed to the top of the warp knitting machine body 1. The air inlet of the first negative pressure fan 121 is connected to an air intake 122, which is located on the top of the warp knitting machine body 1 near the filter placement slot 11. The air outlet of the first negative pressure fan 121 is connected to a first pipe 123. A cavity is also provided on the side of the warp knitting machine body 1 away from the filter placement slot 11, and one end of the first pipe 123 extends into the cavity. The collection assembly 12 also includes a second negative pressure fan 125 fixed inside the warp knitting machine body 1. The air outlet of the second negative pressure fan 125 is connected to a second pipe 124, one end of which is connected to the first pipe 123. The air inlet of the second negative pressure fan 125 is located away from the filter placement slot 11. The collection assembly 12 also includes a collection box 126 slidably disposed in the cavity inside the warp knitting machine body 1.
[0034] After the dust and lint on the filter body 131 are shaken off, the first negative pressure fan 121 and the second negative pressure fan 125 are started simultaneously. The suction generated by the two fans works together to draw the dust and lint on both sides of the filter body 131 into the collection box 126, so as to achieve centralized collection of dust and lint for subsequent unified treatment.
[0035] Working Principle: When the dust or lint accumulated on the surface of the filter body 131 reaches a certain level, the system initiates the cleaning process. First, the rotary drive 1324 is activated, driving the second pulley 13241 on it to rotate. The second pulley 13241 drives the first pulley 13232 to rotate synchronously via belt drive. The rotation of the first pulley 13232 then drives the crankshaft 1323 to rotate periodically. The rotation of the crankshaft 1323 is converted into linear movement of the transmission rod 1325, which in turn pushes the transmission sleeve 1326 to reciprocate along a fixed path. The reciprocating motion of the transmission sleeve 1326 causes the second spring 1327 to reciprocate and deform, causing the connecting rod 1311 to drive the filter body 131 to vibrate. This shakes off the dust and lint on the filter body 131. At the same time, in order to collect the shaken-off dust and lint, the system simultaneously starts the first negative pressure fan 121 and the second negative pressure fan 125. Dust and lint from both sides of the filter body 131 are drawn in and guided through the air duct to the collection box 126 for centralized storage. Through the above process, the system achieves automatic cleaning of the filter body 131 and effective collection of dust and lint, providing convenience for subsequent processing.
[0036] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
