Description

Technical Field

[0001] This utility model is a warp knitting machine with static elimination function, belonging to the field of warp knitting machine weaving. Background Technology

[0002] Warp knitting machines are textile machines that form fabrics by looping warp yarns together. They are widely used in clothing, home textiles, and industrial textiles. During high-speed knitting, friction between the yarns and metal parts can easily generate static electricity, causing the yarns to attract environmental dust, become entangled, and even break, severely affecting fabric quality and production efficiency.

[0003] In the textile industry, the hazards of static electricity are mainly manifested in the following aspects:

[0004] Static electricity can cause entanglement between fibers, yarns, and fabrics, increasing operational difficulty and reducing production efficiency. During spinning, static electricity reduces fiber cohesion, making them prone to tangling around rollers and skin rollers, and even causing yarn breakage, thus affecting spinning quality and subsequent processes. During weaving, static electricity can also disrupt the normal operation of the loom, leading to excessive static electricity during weaving, causing yarn entanglement and breakage, and reducing fabric quality.

[0005] Static electricity makes fibers, yarns, and fabrics more prone to tangling, increasing the complexity and difficulty of operation and thus reducing production efficiency. This phenomenon is particularly pronounced with monofilament yarns or yarns that are prone to static electricity. Although modern warp knitting equipment is equipped with yarn separating needles to disperse the yarn, the effect is still limited. There is a certain distance between the yarn separating needles and the knitting area, making the physical mechanical yarn separating effect insignificant. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a warp knitting machine with anti-static function. This solves the problem that during the spinning process, static electricity can reduce the cohesion between fibers, making them prone to tangling around rollers and skin rollers, and even causing yarn breakage, thus affecting the spinning quality and subsequent processes. During the weaving process, static electricity can also affect the normal operation of the loom, causing a large amount of static electricity to cause yarn tangling and breakage, reducing the quality of the fabric.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a warp knitting machine with anti-static function, comprising:

[0008] The main frame includes symmetrically arranged support frames on the left and right and a crossbeam between the tops of the two support frames. Both the support frames and the crossbeam are provided with several sets of warp shafts.

[0009] A loop-forming mechanism is located inside the main frame body, and the loop-forming mechanism includes a needle bed and a first drive unit for driving the needle bed;

[0010] A combing mechanism is located above a loop-forming mechanism. The combing mechanism includes several combs, a combing cradle, and a second drive unit for driving the combing cradle to swing. The combs are mounted on the combing cradle, and the top of the combs is provided with an antistatic eliminator for eliminating static electricity in the yarn.

[0011] Before the yarn is conveyed to the yarn forming mechanism and the carding mechanism to form the yarn weaving area, the static eliminator eliminates static electricity on the yarn on the carding.

[0012] Furthermore, the top of the combing mechanism is provided with a yarn guiding mechanism for yarn transport. The yarn guiding mechanism includes a plurality of yarn guiding frames corresponding to the combing and support plates fixedly connected to the main body of the frame at both ends of the yarn guiding frames. The static eliminator is correspondingly arranged on the yarn guiding frame.

[0013] Furthermore, a disc head is fitted onto the warp beam, and each disc head is respectively provided with a yarn separating frame. The yarn separating frame corresponding to each warp beam is also provided with an electrostatic eliminator for eliminating static electricity in the yarn.

[0014] Furthermore, a connecting plate is fixedly installed between the symmetrically arranged crossbeams, and a fastener is fixedly installed on the connecting plate for fixing the static eliminator.

[0015] Furthermore, it also includes a yarn rack for storing yarn, the yarn rack being provided with several yarn collecting plates, and the yarn collecting plates being provided with static eliminators for eliminating static electricity.

[0016] Furthermore, a fixing seat is provided below the yarn collecting plate and is fixedly connected to the yarn frame. The fixing seat is used to place the static eliminator.

[0017] Furthermore, the static eliminator is equipped with a high-voltage power generator for power supply, and one end of the static bar is connected to a high-voltage line, and the static bar is electrically connected to the high-voltage power generator through the high-voltage line.

[0018] Furthermore, the static eliminator is a DC static eliminator with an ion fan.

[0019] The beneficial effects of this utility model are: by integrating advanced static elimination technology, this utility model ensures that the yarn can be fully dispersed before entering the weaving area, avoiding tangling and breakage, thereby improving production efficiency and product quality.

[0029] 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.

[0030] Example 1

[0031] Figure 1 This is a schematic diagram of the static eliminator setup for a weaving mechanism according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the knitting mechanism of a warp knitting machine with anti-static function according to an embodiment of the present invention. Figure 3This is a schematic diagram of the overall structure of a warp knitting machine with anti-static function according to an embodiment of the present invention.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, a knitting mechanism structure of a warp knitting machine with anti-static function according to an embodiment of the present invention will be described in detail.

[0033] The warp knitting machine with anti-static function according to an embodiment of the present invention includes a frame body 1, which includes a support frame 11 symmetrically arranged on the left and right and a crossbeam 12 disposed between the tops of the two support frames 11. Both the support frames 11 and the crossbeam 12 are provided with a plurality of warp beams 14; a loop forming mechanism 2, disposed inside the frame body 1, the loop forming mechanism 2 including two needle beds 21 symmetrically arranged front and back and a first drive unit 22 for driving the needle beds 21; and a guide bar mechanism 3, the guide bar... Mechanism 3 is located above loop forming mechanism 2. The combing mechanism 3 includes several combs 31, comb cradle 32, and a second drive unit 33 for driving the comb cradle 32 to swing. The combs 31 are mounted on the comb cradle 32. The top of the combs 31 is provided with an electrostatic eliminator 17 for eliminating static electricity in the yarn. Before the yarn is conveyed to form a yarn weaving area between the loop forming mechanism 2 and the combing mechanism 3, the electrostatic eliminator 17 eliminates static electricity in the yarn on the combs 31.

[0034] Figure 1 This is a schematic diagram illustrating the static eliminator setup of a braiding mechanism according to an embodiment of the present invention. Figure 1 As shown, the arrangement of the static eliminator 17 on the yarn guiding mechanism 5 according to an embodiment of the present invention will be described in detail.

[0035] To eliminate static electricity, the top of the combing mechanism 3 is equipped with a yarn guiding mechanism 5 for yarn transport. The yarn guiding mechanism 5 includes several yarn guide frames 51 corresponding to the combing mechanism 31 and support plates 52 fixedly connected to the machine frame body 1 at both ends of the yarn guide frames 51. The static eliminator 17 is correspondingly installed on the yarn guide frames 51. Due to the high-speed operation of the machine, frequent friction between the yarn and machine parts can easily lead to the generation of static electricity, which can affect the normal operation of the loom, causing a large amount of static electricity to occur during the weaving process, resulting in yarn entanglement and breakage, and reducing the quality of the fabric. Therefore, the static eliminator 17 is installed at the point closest to the yarn entering the weaving area. The yarn guiding mechanism 5 concentrates and lays the yarn in an orderly manner to transport it to the weaving area for weaving. By setting the static eliminator 17 here, the static electricity generated by the yarn during the weaving process can be efficiently eliminated. This avoids adjacent yarns sticking together due to static electricity, which can cause entanglement, breakage, and other phenomena. It ensures that the yarn can be fully dispersed before entering the weaving area, avoiding entanglement and breakage.

[0036] Figure 6This is a schematic diagram of the structure of an electrostatic eliminator according to an embodiment of the present invention. Figure 6 As shown, the structure of the static eliminator according to an embodiment of the present invention will be described in detail.

[0037] The static eliminator 17 is embedded with several discharge needles. The high-voltage corona discharge at the tip of the discharge needles ionizes the air into positive and negative ions. The simultaneous operation of multiple discharge needles can expand the ionization area, allowing more air to be ionized into positive and negative ions, thereby eliminating static electricity more effectively.

[0038] Among them, the static eliminator 17 forms a high-intensity electric field under the high voltage generated by the high voltage power generator 19, ionizing the air to form plasma. These plasmas reach the surface of the object and eliminate static electricity by neutralizing positive and negative charges. It can fully cover the combing working area, ensuring that static electricity in the yarn is eliminated in time during operation, thereby improving production efficiency and product quality.

[0039] This application preferably uses a DC static eliminator with an ion fan, which uses a built-in fan to quickly blow ionized positive and negative ions toward the target surface, increasing the ion delivery volume and allowing more positive and negative ions to quickly reach the yarn surface, accelerating the static neutralization speed and improving the static elimination effect. However, the use of other static elimination devices is not excluded.

[0040] Figure 3 This is a schematic diagram of the overall structure of a warp knitting machine with anti-static function according to an embodiment of the present invention. Figure 3 As shown, the power source of the static eliminator 17 according to an embodiment of the present invention will be described in detail.

[0041] To maintain the stability of the static eliminator, a high-voltage power generator is provided for power supply. One end of the static eliminator 17 is connected to a high-voltage line 19. The static eliminator 17 is electrically connected to the high-voltage power generator 18 via the high-voltage line 19. The high-voltage line 19 conducts voltage to the static eliminator 17 to ensure stable operation of the static elimination function, thus improving operational stability. The static eliminator 17 is made of high-temperature and corrosion-resistant materials, capable of adapting to the high-temperature and high-speed working environment of warp knitting machines, ensuring stable static elimination during long-term operation. Simultaneously, the high-voltage power generator 18 provides a stable high-voltage power supply, ensuring the continuous generation of an effective ionization field, unaffected by external factors.

[0042] Example 2

[0043] For the sake of brevity, the parts that are the same as those in other embodiments will not be described again. The main focus is on the structure that is different from other embodiments of this utility model. The difference between Embodiment 2 and Embodiment 1 is that the static eliminator 17 is added and installed on the yarn separating frame of the yarn head.

[0044] Figure 4 This is a schematic diagram of the static eliminator for the yarn separating needle according to an embodiment of the present invention. Figure 5 This is a schematic diagram illustrating the installation of an electrostatic eliminator on a headstock according to an embodiment of the present invention. Figure 4 and Figure 5 As shown, the static eliminator 17 according to an embodiment of the present invention will be described in detail on the yarn splitter.

[0045] To improve yarn quality and eliminate static electricity, a warp beam 14 is fitted with a warp head 15. Each warp head 15 is respectively equipped with a yarn separating frame 16. Each yarn separating frame 16 corresponding to the warp beam 14 is also equipped with a static eliminator 17 for eliminating yarn static electricity. The yarn separating frame 16 is an important point through which the yarn passes after being drawn from the warp head 15. By setting up an additional static elimination process before the yarn is conveyed to the yarn guiding mechanism 5, it helps improve yarn quality and prevent yarn tangling and breakage. A connecting plate 61 is fixedly installed between the symmetrically arranged crossbeams 12. A fixing member 62 is fixedly installed on the connecting plate 61 for fixing the static eliminator 17. The static eliminator 17 is positioned directly opposite the yarn. To ensure that all yarns are evenly distributed with positive and negative ions, the yarns are fully dispersed, avoiding entanglement and breakage, thus achieving a better static elimination effect. During the spinning process, due to the adsorption or repulsion of static electricity, the cohesion between fibers becomes poor, making it easy for fibers to entangle with rollers, leather rollers, or skip stitches, and even leading to breakage. It can also affect the tightness of the yarn during weaving, causing skipped stitches, missing stitches, or vertical stripes. In view of these phenomena, this embodiment simultaneously sets the static eliminator 17 at two key positions, the yarn guide mechanism 5 and the yarn separator 16, to control the process of the yarn being introduced from the yarn head 15 to the yarn guide mechanism 5 for distribution. This ensures that the yarn is in a completely static-free state when transported on the weaving and transport path of the warp knitting machine, thereby improving the weaving quality of the warp knitting machine.

[0046] Example 3

[0047] For the sake of brevity, the parts that are the same as those in other embodiments will not be described again. The main focus is on the structure that is different from other embodiments of this utility model. The difference between Embodiment 2 and Embodiment 1 is that the static eliminator 17 is added and disposed on the yarn frame.

[0048] Figure 7 This is a schematic diagram illustrating the installation of a static eliminator on a yarn rack according to another embodiment of the present invention. Figure 7 As shown, the installation of the static eliminator 17 on the yarn frame 4 of the whole machine according to another embodiment of the present invention will be described in detail.

[0049] To further prevent yarn breakage and tangling, a yarn rack 4 for storing yarn is also included. The yarn rack 4 is equipped with several yarn collecting plates 41, and each yarn collecting plate 41 is equipped with an electrostatic eliminator 17 for eliminating static electricity. The electrostatic eliminator 17 can also be installed on the yarn rack 4 to eliminate static electricity in advance before the yarn enters the warp knitting machine. Below the yarn collecting plates 41 is a fixing seat 42 that is fixedly connected to the yarn rack 4. The fixing seat 42 is used to place the electrostatic eliminator 17. The fixing seat 42 is fixed to the yarn rack 4 by bolts using two positioning plates, which is convenient and secure. On the path of the yarn output from the yarn rack 4 to the warp knitting machine, static electricity is easily generated due to high-speed operation and friction with air and equipment parts. As another crucial point where yarn is output to the warp knitting machine, the yarn frame 4 is equipped with an electrostatic eliminator 17 to pre-treat the yarn for static elimination. This ensures that the yarn is in a static-free or low-static-state before entering the warp knitting machine, thereby reducing the impact of static electricity on subsequent warp knitting machine production processes. The yarn is simultaneously eliminated for static electricity as it is output from the yarn collecting plate 41, achieving full-path static elimination of the yarn from the yarn frame 4 to the warp knitting machine. This more effectively prevents yarn from winding around the rollers, wrapping around the leather rollers, sticking, and breaking, promoting smooth spinning and significantly improving yarn quality.

[0050] Example 4

[0051] For the sake of brevity, the parts that are the same as those in other embodiments will not be described again. The main focus is on the structure that is different from other embodiments of this utility model. The difference between embodiment 4 and other embodiments is that the static eliminator 17 is only provided on the yarn separating frame 16.

[0052] Figure 1 This is a schematic diagram illustrating the static eliminator setup of a braiding mechanism according to an embodiment of the present invention. Figure 1 As shown, the static eliminator 17 according to another embodiment of the present invention will be described in detail only on the yarn guiding mechanism 5.

[0053] To eliminate static electricity, the static eliminator 17 is only installed on the yarn guiding mechanism 5. The yarn separating frame 16 is a crucial point where the yarn passes through after being led out from the yarn head 15. Frequent friction occurs between the yarn and the separating needles on the yarn separating frame 16, easily generating static electricity. Static electricity can cause the yarns to stick together and become tangled, leading to yarn breakage and affecting production efficiency. By installing the static eliminator 17 on the yarn separating frame 16, the static electricity carried by the yarn can be neutralized in a timely manner, preventing problems such as tangling and yarn breakage during the yarn separating process, improving the stability of yarn operation, and ensuring continuous production.

[0054] Example 5

[0055] For the sake of brevity, the parts that are the same as those in other embodiments will not be described again. The main focus is on the structure that is different from other embodiments of this utility model. The difference between embodiment 5 and other embodiments is that the static eliminator 17 is only provided on the yarn frame 4.

[0056] Figure 7 This is a schematic diagram illustrating the installation of a static eliminator on a yarn rack according to another embodiment of the present invention. Figure 7 As shown, the static eliminator 17 according to another embodiment of the present invention will be described in detail only on the yarn frame 4 of the whole machine.

[0057] To prevent static electricity from affecting the yarn being knitted by the warp knitting machine, the static eliminator 17 is only installed on the yarn frame 4. As the yarn slides at high speed on the yarn guide component of the yarn frame 4, it generates intense friction, causing the yarn to become statically charged. This static electricity can cause the yarn to attract dust and impurities from the air, and may also cause a large amount of fly yarn and yarn breakage during weaving, affecting the weaving quality of subsequent warp knitting machines. Therefore, by installing a static eliminator on the yarn frame 4, the static electricity carried by the yarn can be neutralized in a timely manner, preventing problems such as yarn tangling and breakage during transport due to static electricity. It also reduces the fuzziness and mutual repulsion of the yarn caused by static electricity during transport, resulting in neater yarn, improved yarn running stability, and ensured continuous production.

[0058] In use, the yarn is conveyed from the yarn head 15 to the corresponding yarn separating frame 16. Several yarn separating needles on the yarn separating frame 16 evenly separate the yarn group by equidistant arrangement, preventing adjacent yarns from tangling during high-speed conveying. At this time, the static eliminator 17 set on the yarn separating frame 16 starts to work, ionizing the air through high-voltage discharge to form positive and negative ions, which are then blown onto the surface of the yarn to neutralize the positive and negative static ions, thereby achieving the purpose of efficient and reliable elimination of static electricity, thus completing the first static elimination process. Then, it is conveyed to the yarn guiding mechanism 5. At this time, the static eliminator 17 set on the top of the yarn guiding frame 51 starts to work to eliminate static electricity in the yarn, thus completing the second static elimination process. Finally, it is conveyed to the weaving area for weaving. This utility model integrates advanced static elimination technology and sets static eliminators in key areas of yarn weaving to ensure that the yarn undergoes multiple static elimination processes before entering the weaving area, which can make the yarn fully dispersed and avoid tangling and breakage, thereby improving production efficiency and product quality.
