Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of textile processing equipment, and in particular relates to a jacquard circular knitting machine with a yarn tension adjustment function. Background Art
[0002] Jacquard circular machine is a common circular knitting machine. Jacquard technology refers to the concave and convex pattern of textiles composed of interlaced warp and weft threads.
[0003] The existing Chinese patent with publication number CN213708675U discloses a jacquard circular machine with a dust removal device, which includes a support frame and a yarn frame, and also includes a dust removal device. The dust removal device includes a plurality of exhaust fans arranged on the support frame, and an exhaust pipe is arranged on the exhaust fan, and the exhaust pipe is arranged directly opposite to the axis of the spinning frame.
[0004] Although the jacquard circular knitting machine can reduce the probability of dust adhering to the yarn, it cannot adjust the tension of the yarn. If the tension of the yarn is too large, the parts in contact with the yarn are easily damaged by the wear of the yarn, and it is difficult to replace the parts. If the tension is uneven, the quality of the cloth will be affected. Utility Model Content
[0005] The purpose of this application is to provide a jacquard circular machine with a yarn tension adjustment function in order to solve the above-mentioned technical problems. The jacquard circular machine can adjust the tension of the yarn, and the parts in contact with the yarn can reduce wear and tear, thereby increasing the service life, and the quality of the produced cloth is higher.
[0006] The present application provides a jacquard circular knitting machine with a yarn tension adjustment function, comprising a housing, wherein the housing comprises:
[0007] A tension adjustment mechanism, comprising an adjustment rod and a slider;
[0008] A mounting frame, including a yarn guide wheel and a slide rail;
[0009] Cleaning agencies;
[0010] Wherein, the yarn guide wheel is connected to the tension adjustment mechanism, the adjustment rod is connected to the slider, and the slider is matched with the slide rail.
[0011] In the present technical scheme, an adjusting rod and a slider are arranged on the tension adjusting mechanism, and a yarn guide wheel and a slide rail are arranged on the mounting frame. The adjusting rod can slide on the mounting frame through the cooperation between the slider and the slide rail. The sliding adjusting rod changes the position of the adjusting rod, thereby adjusting the tension of the yarn. When the yarn tension is large, reducing the yarn tension can prevent the yarn guide wheel from being damaged due to large wear and tear, and can prevent the yarn from being broken due to excessive force. When the yarn tension is small, increasing the yarn tension can balance the tension of each yarn, so as to improve the quality of the finished cloth. A cleaning mechanism is installed on the shell to keep the yarn surface clean, thereby improving the degree of cooperation between the adjusting rod and the yarn, accelerating the efficiency of the tension adjusting mechanism in adjusting the yarn tension, and further improving the quality of the finished cloth.
[0012] Furthermore, the tension adjustment mechanism comprises:
[0013] First motor;
[0014] A screw rod connected to the first motor;
[0015] A tension sensor connected to the first motor;
[0016] An automatic stop device connected to the tension sensor;
[0017] Wherein, the adjusting rod is provided with a screw hole, and the screw hole cooperates with the screw rod.
[0018] In the present technical solution, a tension sensor and a first motor with a screw rod are arranged on the tension adjustment mechanism, a screw hole is arranged in the adjustment rod, the adjustment rod is translated through the cooperation between the screw hole and the screw rod, the tension sensor is connected to the first motor, when the tension sensor detects that the tension is large, it controls the first motor to rotate forward, so that the axis center of the adjustment rod is translated close to the straight line formed by the axis center of the tension sensor and the axis center of the yarn guide wheel, thereby reducing the tension on the yarn, when the tension sensor detects that the tension is small, it controls the first motor to reverse, so that the axis center of the adjustment rod is translated away from the axis center of the tension sensor and the yarn guide wheel The straight line between the axles of the wheels increases the tension on the yarn. The tension adjusting mechanism is also provided with an automatic stop device, which is placed in the shell. When the value of the tension sensor is continuously too large, too small or zero, it indicates that the component controlling the yarn on the jacquard circular machine has failed or the yarn has been disconnected, and the operator needs to repair it. At this time, the tension sensor starts the automatic stop device and the jacquard circular machine stops working to remind the operator to check and repair the jacquard circular machine. The jacquard circular machine stops working in time when a problem occurs, which can avoid producing too much fabric of poor quality, reduce the waste of raw materials and improve the quality of the product.
[0019] Furthermore, the automatic stopping device comprises:
[0020] An auxiliary frame, which cooperates with the shell;
[0021] a permanent magnet including a first contact;
[0022] an electromagnet including a second contact;
[0023] A return spring connected between the housing and the electromagnet;
[0024] Among them, the permanent magnet is connected to the auxiliary frame, the electromagnet is connected to the tension sensor, the first contact is connected to the power supply, the electromagnet is connected to the permanent magnet after being energized, and the second contact cooperates with the first contact.
[0025] In the present technical solution, a permanent magnet with a first contact and an electromagnet with a second contact are arranged on the automatic stop device, the permanent magnet is connected to the auxiliary frame, and the electromagnet is connected to the shell through a reset spring. When the tension sensor is working normally, the electromagnet is connected to the permanent magnet after being energized. At this time, the first contact is connected to the second contact, and the jacquard circular machine is powered on and works normally. When the tension sensor detects that the tension is continuously too large, too small or zero, the electromagnet is reset by the reset spring after power is cut off and disconnected from the permanent magnet. At this time, the first contact is disconnected from the second contact, and the jacquard circular machine disconnects the power supply and stops working. An infrared lamp is installed on the tension sensor. After the electromagnet is powered off, the infrared lamp starts to work, prompting the staff that there is a problem with the component, so that the staff can quickly repair the jacquard circular machine, improve the speed of repair work, and thus speed up production efficiency.
[0026] Furthermore, the adjusting rod comprises:
[0027] Wear rods, including clips;
[0028] The card slot cooperates with the buckle.
[0029] In the present technical scheme, since the tension on the adjusting rod changes frequently, the adjusting rod is subject to severe wear. A slot is provided on the adjusting rod, a buckle is provided on the wear-resistant rod, and the wear-resistant rod is installed on the adjusting rod through the cooperation of the buckle and the slot. The yarn is put on the wear-resistant rod and the adjusting rod. The wear-resistant rod can greatly reduce the wear on the adjusting rod and reduce the impact of wear on the adjusting rod. When the adjusting rod and the wear-resistant rod cannot work normally due to wear, since the replacement of the wear-resistant rod is more convenient than the replacement of the adjusting rod and the cost of the wear-resistant rod is lower, the wear-resistant rod is preferably selected rather than the adjusting rod when replacing the worn parts, thereby saving the use cost of the jacquard circular machine and improving the working efficiency of the jacquard circular machine.
[0030] Furthermore, the mounting frame includes:
[0031] Pulleys, including wire grooves;
[0032] Wherein, the pulley is rotationally connected to the mounting frame.
[0033] In the present technical scheme, a pulley with a wire groove is arranged on the mounting frame, and the pulley is rotatably installed on the mounting frame. The yarn is transmitted to the yarn guide wheel after passing through the pulley. The pulley can reduce the friction between the yarn and the yarn guide wheel, and reduce the wear of the yarn on the yarn guide wheel. The surface of the pulley is provided with a wire groove, which can prevent the yarn from falling off the pulley due to shaking, so that the yarn can be transported stably. According to the above technical features, the replacement frequency of the yarn guide wheel can be reduced, and the stability of the jacquard circular machine during the yarn feeding process can be improved.
[0034] Furthermore, the cleaning mechanism comprises:
[0035] Second motor;
[0036] A rotating frame connected to the second motor;
[0037] The nozzle is connected to the rotating frame.
[0038] In the present technical solution, a second motor and a rotating frame are arranged on the cleaning mechanism, and a nozzle is installed at the port of the rotating frame. When the jacquard circular machine is cleaned by the cleaning mechanism, the second motor needs to be started, and the second motor drives the rotating frame to rotate. At the same time, the nozzle is turned on. The nozzle can spray the detergent in all directions through the rotation of the rotating frame to reduce the dust generated when the jacquard circular machine is working, and prevent the surface of the yarn from being contaminated with too much dust during the transportation process. The surface of the yarn is cleaned to a high degree, which is convenient for the tension adjustment mechanism to adjust the tension of the yarn, thereby improving the quality of the finished cloth.
[0039] The beneficial effects of this application are:
[0040] 1. The adjusting rod slides on the mounting frame through the cooperation between the slider and the slide rail. The yarn tension can be adjusted by changing the position of the adjusting rod, which can prevent the yarn from breaking due to excessive tension and avoid the uneven tension on each yarn affecting the quality of the finished cloth. A cleaning mechanism is installed on the shell to keep the yarn surface clean, and the cooperation between the adjusting rod and the yarn is tighter, which speeds up the efficiency of adjusting the tension.
[0041] 2. A tension sensor and a first motor with a screw rod are installed on the tension adjustment mechanism. A screw hole is provided in the adjustment rod. The adjustment rod is translated through the cooperation between the screw hole and the screw rod. When the tension sensor detects that the tension is large, it controls the first motor to rotate forward, so that the adjustment rod translates forward, reducing the tension on the yarn. When the tension sensor detects that the tension is small, it controls the first motor to reverse, so that the adjustment rod translates in the opposite direction, increasing the tension on the yarn, thereby realizing the function of the tension adjustment mechanism to adjust the tension on the yarn.
[0042] 3. When the tension sensor is working normally, the electromagnet is energized and connected to the permanent magnet, the first contact of the permanent magnet is connected to the second contact of the electromagnet, and the jacquard circular machine is powered on and works normally. When the tension sensor detects an abnormal tension value, the electromagnet is disconnected from the permanent magnet, the first contact is disconnected from the second contact, and the jacquard circular machine is disconnected from the power supply and stops working, thereby realizing the function of automatically stopping the jacquard circular machine.

In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0050] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.
[0051] Embodiment 1:
[0052] like Figure 1-4 As shown, the embodiment of the present application provides a jacquard circular knitting machine with a yarn tension adjustment function, including a housing 100, wherein the housing 100 includes:
[0053] The tension adjustment mechanism 200 includes an adjustment rod 210 and a slider 220;
[0054] The mounting frame 300 includes a yarn guide wheel 310 and a slide rail 320;
[0055] Cleaning mechanism 400;
[0056] The yarn guide wheel 310 is connected to the tension adjustment mechanism 200 , the adjustment rod 210 is connected to the slider 220 , and the slider 220 is matched with the slide rail 320 .
[0057] By arranging an adjusting rod 210 and a slider 220 on the tension adjustment mechanism 200, and arranging a yarn guide wheel 310 and a slide rail 320 on the mounting frame 300, the adjusting rod 210 can slide on the mounting frame 300 through the cooperation between the slider 220 and the slide rail 320, and the sliding adjusting rod 210 changes the position of the adjusting rod 210, thereby adjusting the tension of the yarn. When the yarn tension is large, reducing the yarn tension can prevent the yarn guide wheel 310 from being damaged by large wear and tear, and can prevent the yarn from being broken due to excessive force. When the yarn tension is small, increasing the yarn tension can balance the tension of each yarn, so as to improve the quality of the finished cloth. A cleaning mechanism 400 is installed on the shell 100 to keep the yarn surface clean, thereby improving the degree of cooperation between the adjusting rod 210 and the yarn, accelerating the efficiency of the tension adjustment mechanism 200 in adjusting the yarn tension, and further improving the quality of the finished cloth.
[0058] Furthermore, the tension adjustment mechanism 200 includes:
[0059] A first motor 230;
[0060] A screw rod 240 connected to the first motor 230;
[0061] A tension sensor 250 connected to the first motor 230;
[0062] An automatic stop device 260 connected to the tension sensor 250;
[0063] The adjusting rod 210 is provided with a screw hole 211 , and the screw hole 211 is matched with the screw rod 240 .
[0064] By arranging a tension sensor 250 and a first motor 230 with a screw rod 240 on the tension adjustment mechanism 200, and arranging a screw hole 211 in the adjustment rod 210, the adjustment rod 210 is translated through the cooperation between the screw hole 211 and the screw rod 240, and the tension sensor 250 is connected to the first motor 230. When the tension sensor 250 detects that the tension is large, it controls the first motor 230 to rotate forward, so that the axis of the adjustment rod 210 is translated close to the straight line formed by the axis of the tension sensor 250 and the axis of the yarn guide wheel 310, thereby reducing the tension on the yarn. When the tension sensor 250 detects that the tension is small, it controls the first motor 230 to reverse, so that the axis of the adjustment rod 210 is translated away. The straight line formed between the axis of the tension sensor 250 and the axis of the yarn guide wheel 310 increases the tension on the yarn. The tension adjustment mechanism 200 is also provided with an automatic stop device 260, which is placed in the housing 100. When the value of the tension sensor 250 is continuously too large, too small or zero, it indicates that the component controlling the yarn on the jacquard circular machine has failed or the yarn has been disconnected, and the operator needs to repair it. At this time, the tension sensor 250 starts the automatic stop device 260, and the jacquard circular machine stops working, which is used to remind the operator to check and repair the jacquard circular machine. The jacquard circular machine stops working in time when a problem occurs, which can avoid producing too much fabric of poor quality, reduce the waste of raw materials and improve the quality of the product.
[0065] Furthermore, the automatic stopping device 260 includes:
[0066] An auxiliary frame 261, which cooperates with the housing 100;
[0067] A permanent magnet 262 including a first contact 265;
[0068] an electromagnet 263 including a second contact 266;
[0069] a return spring 264 connected between the housing 100 and the electromagnet 263;
[0070] Among them, the permanent magnet 262 is connected to the auxiliary frame 261, the electromagnet 263 is connected to the tension sensor 250, the first contact 265 is connected to the power supply, the electromagnet 263 is connected to the permanent magnet 262 after being energized, and the second contact 266 cooperates with the first contact 265.
[0071] By arranging a permanent magnet 262 with a first contact 265 and an electromagnet 263 with a second contact 266 on the automatic stop device 260, the permanent magnet 262 is connected to the auxiliary frame 261, and the electromagnet 263 is connected to the housing 100 through a reset spring 264. When the tension sensor 250 works normally, the electromagnet 263 is connected to the permanent magnet 262 after being energized. At this time, the first contact 265 is connected to the second contact 266. The jacquard circular knitting machine works normally when the power is turned on. When the tension sensor 250 When it is detected that the tension is continuously too large, too small or zero, the electromagnet 263 is reset by the reset spring 264 after power is cut off, and is disconnected from the permanent magnet 262. At this time, the first contact 265 and the second contact 266 are disconnected, and the jacquard circular machine is disconnected from the power supply and stops working. An infrared lamp is installed on the tension sensor 250. After the electromagnet 263 is powered off, the infrared lamp starts to work, prompting the staff that there is a problem with the component, so that the staff can quickly repair the jacquard circular machine, improve the speed of repair work, and thus speed up production efficiency.
[0072] Furthermore, the adjusting rod 210 includes:
[0073] A wear-resistant rod 212, including a buckle 214;
[0074] The card slot 213 cooperates with the card buckle 214 .
[0075] Since the tension on the adjusting rod 210 changes frequently, the adjusting rod 210 is subject to severe wear. By providing a slot 213 on the adjusting rod 210 and a buckle 214 on the wear-resistant rod 212, the wear-resistant rod 212 is installed on the adjusting rod 210 through the cooperation of the buckle 214 and the slot 213, and the yarn is put on the wear-resistant rod 212 and the adjusting rod 210. The wear-resistant rod 212 can greatly reduce the wear on the adjusting rod 210 and reduce the influence of wear on the adjusting rod 210. When the adjusting rod 210 and the wear-resistant rod 212 cannot work normally due to wear, since the wear-resistant rod 212 is more convenient to replace than the adjusting rod 210 and the wear-resistant rod 212 has a lower cost, the wear-resistant rod 212 is preferably selected rather than the adjusting rod 210 when replacing the worn parts, thereby saving the use cost of the jacquard circular machine and improving the working efficiency of the jacquard circular machine.

The yarn is transmitted to the yarn guide wheel 310 after passing through the pulley 330. The pulley 330 can reduce the friction between the yarn and the yarn guide wheel 310, and reduce the wear of the yarn on the yarn guide wheel 310. The surface of the pulley 330 is provided with a wire groove 331, which can prevent the yarn from falling off the pulley 330 due to shaking, so that the yarn can be transported stably.
