Abstract
Description
Technical Field
[0001] The invention relates to the field of textile technology, in particular to a yarn twisting device for textile processing. Background Art
[0002] The twisting machine is a textile mechanical equipment that twists multiple strands of yarn into one strand. Its function is to process yarn or combined strands of yarn into linear products for weaving and knitting. It consists of a twisting machine body and a circuit part. The spindle outside the twisting machine body is connected to the motor output shaft of the circuit part, and the front end of the spindle is provided with a connector corresponding to the tap switch.
[0003] In existing production, in order to obtain yarn with specific properties, such as elastic yarn, usually, elastic fibers are twisted together with other fibers. When the elastic yarn is pulled, the elastic fibers are deformed to avoid damage to the elastic fibers. After the elastic fibers are deformed to a certain length, other fibers need to be stressed to prevent the elastic yarn from becoming longer. The above-mentioned properties require that the length of the elastic fibers be controlled to be less than the length of other fibers during twisting. In existing production processes, fibers of the same length are mostly twisted. Summary of the invention
[0004] In order to solve the above problems, the present invention discloses a twisting device for textile processing, including a shell, the upper side wall of the shell extends the main shaft, and the end of the main shaft is fixedly connected to a rotating disk, the edge of the rotating disk is fixedly connected to a plurality of pay-off units, a step tube is provided at the front axis of the rotating disk, and the step tube is provided with circumferential surfaces of different diameters, and the end of the step tube is fixedly connected to a wire guide tube. During the rotation of the rotating disk, the yarn on the pay-off unit is wound on the step tube. During the production process, different types of yarns require different lengths when they are combined. For example, when elastic fibers and plastic fibers are twisted, in order to ensure elasticity after being combined, the length of the plastic fibers is greater than that of the elastic fibers. The present invention winds different types of yarns on different direct circumferential surfaces. During the winding process, all the yarns are pulled out from one end of the step tube together to obtain composite yarns, which can achieve the above purpose. It should be noted that the yarn can only be pulled out after it is wound around the step tube once, that is, from the second circle.
[0005] An L-shaped plate is fixedly connected to the bottom of the shell, a winding motor is fixedly connected to the back of the L-shaped plate, and a take-up wheel is fixedly connected to the output end of the winding motor, and the take-up wheel is located directly below the wire guide tube. In the process of twisting, after obtaining the composite yarn, it is passed through the middle of the step tube, through the wire guide tube, and sent out from the lower end of the wire guide tube, and finally wound on the winding wheel. It should be noted that in order to prevent the composite yarn from being cut / worn during winding, rounded corners are set at the ends of the step tube and the ends of the wire guide tube.
[0006] Preferably, the pay-off unit comprises a fixed plate, a first motor is fixedly connected to the back of the fixed plate, an output end of the first motor extends to the front of the fixed plate, and a pay-off wheel is fixedly connected to the output end. The first motor is used to control the speed of spinning, that is, to improve the control accuracy of the spinning length during the twisting process.
[0007] Preferably, the end of the output end is fixedly connected with a fixed rotating handle for holding the pay-off wheel. The fixed rotating handle can be manually twisted to facilitate the replacement and fixing of the pay-off wheel.
[0008] Preferably, a fixed arm is fixedly connected to the lower part of the fixed plate, and a third guide ring is fixedly connected to the end of the fixed arm, so as to realize the first guide of the spinning line, and the third guide ring is located directly below the pay-off wheel.
[0009] Preferably, a plurality of rotating arms are provided on the front of the rotating disk, and the number of the rotating arms corresponds to the number of the unwinding units, and the ends of the rotating arms are fixedly connected with first guide rings, and the first guide rings are arranged around the step tube. The rotating arms can rotate, that is, the spatial position of the first guide ring can be adjusted, that is, the spinning line can be guided to the circumferential surfaces of different diameters on the step tube.
[0010] Preferably, a support frame is fixedly connected to the front of the housing, and the wire guide tube is fixed in the middle of the support frame. That is, the support frame is used to fix the wire guide tube. At the same time, since there is a risk of parts being thrown out during the rotation of the rotating disk, the support frame can provide a certain degree of protection.
[0011] Preferably, an electric cylinder is fixedly connected to the upper part of the L-shaped plate horizontally, and an output end extending from one end of the electric cylinder is fixedly connected to a second guide ring, and the second guide ring is located between the take-up wheel and the wire guide tube. The second guide ring is used to guide the composite yarn, and the electric cylinder is actuated to make the second guide ring reciprocate from one end of the take-up wheel to the other end, so that the composite yarn can be evenly wound on the take-up wheel.
[0012] Preferably, at least three dynamic balance adjustment mechanisms are fixedly connected at equal angles to the back of the rotating disk, and the dynamic balance adjustment mechanism includes a frame, and a counterweight block is provided inside the frame for sliding cooperation. Both sides of the counterweight block are provided with protrusions, and the protrusions are matched with the openings preset in the frame. Since the amount of each type of spinning is different during the production process, the geometric center of gravity of the entire rotating system including the rotating disk is not on the rotating axis. Under the premise of ensuring production efficiency, the rotating disk has a high rotation speed, which is very likely to cause dynamic balance problems. The dynamic balance adjustment mechanism is provided to ensure that the rotating system will not have eccentricity problems and to ensure the stable operation of the equipment.
[0013] Preferably, one end of the frame is fixedly connected to a second motor, an output end of the second motor is fixedly connected to a screw, and the screw is threadedly connected to the counterweight.

[0014] The beneficial effects of the present invention are as follows: 1. A stepped tube is provided, and a plurality of pay-off units are provided on the rotating disk. During the rotation of the rotating disk, the spinning unit releases the spinning thread and winds it around the circumferential surfaces of the stepped tube with different diameters, thereby realizing the length control of different types of spinning threads in the middle of the composite spinning thread.
[0015] 2. A dynamic balance adjustment mechanism is provided. During the operation of the twisting equipment, due to the different lengths of the wires used by the pay-off units, that is, the different margins generated, the dynamic balance of the rotating disk is unstable. The dynamic balance adjustment mechanism is provided to adjust the position of the counterweight block to achieve the balance of the rotating disk.
[0016] 3. The first motor, the third guide ring and the first guide ring are provided to ensure that the yarn is accurately wound around the step tube, the yarn length is controlled, and the risk of yarn breakage is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.
[0020] like Figures 1 to 6 As shown, a twisting device for textile processing includes a shell 1, which is a rectangular parallelepiped structure. The upper side wall of the shell 1 is extended by a main shaft, that is, a main driving motor is arranged inside the shell 1, and the output end of the main driving motor is fixedly connected to the main shaft, and a rotating disk 5 is fixedly connected to the end of the main shaft, and the main shaft drives the rotating disk 5 to rotate. A plurality of pay-off units 6 are fixedly connected to the edge of the rotating disk 5. The pay-off units 6 release the spinning thread during the rotation of the rotating disk 5. A stepped tube 8 is arranged at the front axis of the rotating disk 5. The stepped tube 8 does not rotate with the rotating disk 5. The stepped tube 8 is provided with circumferential surfaces of different diameters. During the rotation of the disk 5, the yarn released by the pay-off unit 6 is wound around the step tube 8. At the same time, according to the different amounts of different types of yarn, different types of yarn are controlled to be wound around the circumferential surfaces of different diameters of the step tube 8. The end of the step tube 8 is fixedly connected with a wire guide tube 7. During the winding process, after the yarn is wound around the step tube 8 for the second circle, all the yarns can be pulled from one end of the step tube 8 to obtain a composite yarn, and the composite yarn is turned back and passed through the middle of the step tube 8 into the wire guide tube 7, and sent out from the other end of the wire guide tube 7. Since it is wound around circumferential surfaces of different diameters, different types of yarn have different lengths. It should be noted that in order to avoid the composite yarn from being cut off by the edge when entering the step tube 8 or being sent out from the wire guide tube 7, it is necessary to set the rounded corners at the ends of the step tube 8 and the wire guide tube 7.
[0021] Furthermore, a threaded connection is adopted between the step tube 8 and the wire guide tube 7, that is, different types of step tubes 8 are replaced according to the production of different types of composite yarns. At the same time, in the process of spinning and winding around the step tube 8, the yarn is prevented from slipping. The side wall of the step tube 8 can be roughly provided, or an arc-shaped transition convex ring can be provided on the side wall of each circumferential surface close to the end face. When subjected to tension, the yarn will slip out of the cylindrical surface.
[0022] An L-shaped plate 2 is fixedly connected to the bottom of the shell 1, that is, the L-shaped plate 2 includes a vertical plate and a horizontal plate, one side of the horizontal plate is fixedly connected to the shell 1, and a winding motor is fixedly connected to the back of the L-shaped plate 2, that is, the winding motor is fixedly connected to the vertical plate, and the output end of the winding motor is fixedly connected to a take-up wheel 3, which is located directly below the wire guide tube 7. During operation, the composite yarn is sent out from the lower end of the wire guide tube 7 and is wound on the take-up wheel 3. At this time, the winding motor works to drive the take-up wheel 3 to rotate.
[0023] The pay-off unit 6 includes a fixed plate 65, which is a rectangular plate with rounded corners at all four corners, and bolts are inserted at the four corners, and the bolts are threadedly connected to the rotating disk 5, that is, the fixed plate 65 is fixedly connected to the back of the fixed plate 65. Similarly, a number of bolts pass through the fixed plate 65 and are threadedly connected to the first motor 66. At the same time, a hole for the first motor 66 to pass through is reserved on the rotating disk 5. The output end of the first motor 66 extends to the front of the fixed plate 65, and the pay-off wheel 62 is fixedly connected to the output end. Since the spinning line on the pay-off wheel 62 is relatively thin, if the spinning line is wound around the step tube 8 as the rotating disk 5 rotates, the spinning line will be subjected to a large tension and easily broken. At the same time, there will be a problem that the pay-off length does not meet the expected requirements. Therefore, the first motor 66 is set to control the release degree of the spinning line according to the design requirements during the rotation of the rotating disk 5, so as to improve the accuracy of the pay-off.
[0024] The end of the output end of the first motor 66 is fixedly connected with a fixed handle 61 that buckles the pay-off wheel 62. The fixed handle 61 can be manually rotated and removed from the output end, which is convenient for replacing the pay-off wheel 62. It should be noted that a retaining ring is provided on the output end of the first motor 66, and the pay-off wheel 62 is clamped between the retaining ring and the fixed handle 61.
[0025] The lower part of the fixing plate 65 is fixedly connected with a fixing arm 64, and the end of the fixing arm 64 is fixedly connected with a third guide ring 63. The third guide ring 63 is just located directly below the pay-off wheel 62, and the spinning line passes through the third guide ring 63 for the first time.
[0026] A plurality of rotating arms 10 are arranged on the front of the rotating disk 5, and the number of the rotating arms 10 corresponds to that of the unwinding unit 6. The rotating arms 10 include a fixed seat and a rotating rod. The fixed seat is fixedly connected to the rotating disk 5, and the fixed seat and the rotating rod are connected by rotation, and are manually fixed by bolts or other methods to prevent the position of the rotating rod from changing during the rotation. The end of the rotating arm 10 is fixedly connected to the first guide ring 9, and the first guide ring 9 is arranged around the step tube 8. After the spinning line passes through the third guide ring 63, it passes through the first guide ring 9, and the rotating arm 10 adjusts the spatial position of the first guide ring 9, so as to control different types of spinning lines to be wound on the specified circumferential surface.
[0027] The front of the housing 1 is fixedly connected with a support frame 4, the support rod 4 is constructed of a plurality of rods, and the wire guide tube 7 is fixed in the middle of the support frame 4. The support frame 4 not only supports and fixes the dos dryer, but also protects it to a certain extent, preventing the rotating disk 5 from being thrown out during high-speed rotation of the pay-off wheel 52 and other components.
[0028] An electric cylinder 12 is fixedly connected to the upper horizontal part of the L-shaped plate 2, and an output end extending from one end of the electric cylinder 12 is fixedly connected to a second guide ring 11. The composite yarn passes through the second guide ring 11, and the second guide ring 11 is located between the take-up wheel 3 and the wire guide tube 7. During the operation of the electric cylinder 12, the second guide ring 11 reciprocates from one end of the take-up wheel 3 to the other end, so that the composite yarn is evenly wound around the take-up wheel 3.
[0029] At least three dynamic balancing adjustment mechanisms 13 are fixedly connected at equal angles to the back side of the rotating disk 5, which are used to solve the vibration problem caused by the uneven mass of the rotating disk 5 due to the different usage of the pay-off units 6 on the rotating disk 5. The dynamic balancing adjustment mechanism 13 includes a frame 134, and a counterweight block 133 is provided in a sliding manner inside the frame 134. First, relevant sensors are pre-set to monitor the vibration of the rotating shaft, and then each counterweight block 133 is controlled in a linkage manner to adjust the center of gravity of the rotating disk 5. Bumps are provided on both sides of the counterweight block 133, and the bumps are fitted in the preset openings of the frame 134. This setting prevents the counterweight block 133 from detaching from the frame 134.
[0030] One end of the frame 134 is fixedly connected to the second motor 131, and the output end of the second motor 131 is fixedly connected to the screw 132, and the screw 132 is threadedly connected to the counterweight 133. The second motor 131 is started to drive the screw 132 to rotate, thereby controlling the movement of the counterweight 133. At the same time, a speed reduction mechanism is arranged inside the second motor 131, so that the screw 132 has the performance of low speed and high torque, which is suitable for adjusting the position of the counterweight 133 during the high-speed rotation of the rotating disk 5.
[0031] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
