Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a nylon stretch yarn twisting device. Background Art

[0002] In the textile industry, the twisting device for nylon stretch yarn is a key equipment, which plays a vital role in improving the quality and performance of nylon filament. The design and manufacture of this device not only reflects the technical level of textile machinery, but also is directly related to the development of the textile industry. Nylon stretch yarn is widely used in clothing, sports equipment and other fields due to its excellent elasticity and wear resistance.

[0003] The core technology of the twisting device for nylon stretch yarn is to twist the nylon filaments through mechanical force, that is, to generate sufficient friction between the fibers through rotation and stretching, thereby forming a stable fiber structure. This structure not only increases the strength of the fiber, but also improves its elastic recovery performance. The design of the twisting device needs to take into account the characteristics of the fiber, such as length, fineness, elastic modulus, etc., to ensure that the twisting effect meets the production requirements.

[0004] The device usually consists of the following parts: first, the feeding part, which is used to feed the nylon filaments evenly into the twisting area; then the twisting part, which is the core of the device, includes a spindle (or spindle shaft) and a bobbin rotating around it. The spindle generates a strong torque by rotating at high speed, causing the nylon filaments in the bobbin to twist; then the drafting part, which is used to further stretch the twisted fibers to increase their strength and elasticity; and finally the winding part, which winds the twisted nylon stretch yarn into appropriate packages for easy storage and transportation.

[0005] In the twisting process of nylon stretch yarn, it is very important to control the twist degree. The twist degree directly affects the performance of nylon stretch yarn. Too high a twist degree may cause fiber damage and reduce the strength of the fiber; while too low a twist degree cannot achieve the expected elasticity and recovery performance. Therefore, the twisting device is usually equipped with a tension control system to ensure the stability of the fiber tension during the twisting process, so as to obtain an ideal twisting effect.

[0006] In addition, in order to improve production efficiency, the twisting device usually adopts an automated control system, which monitors parameters such as fiber feed amount and twist degree in real time through sensors, and automatically adjusts them through a computer control system to achieve efficient and stable production.

[0007] In summary, the twisting device of nylon stretch yarn is a complex equipment integrating multiple technologies such as mechanics, electronics, and computer control. Its design, manufacture, and use reflect the high-level technology in the field of textile machinery. It is of great significance to improve the quality and performance of nylon stretch yarn, meet market demand, and promote the development of the textile industry.

[0008] The existing twisting device for nylon stretch yarn is generally designed to improve the problem that the current twisting device cannot adjust the position of the guide device, resulting in the same elasticity of nylon stretch yarns of different materials when twisted, especially for ultra-fine nylon stretch yarn, excessive twisting tension is easy to cause breakage and loss. For example, the twisting device for nylon stretch yarn disclosed in the authorized Chinese patent CN213896115U can achieve efficient twisting of different silk threads at the same time through the coordinated use of structures such as a base, a box, a wiring disk, a wire hole, a twisting disk, a driven gear, a driving gear, a driving motor, a guide device, a support rod, a movable seat, a screw rod, a turntable, a fixed shaft, a connecting rod, a slide groove, a pressure plate, a limit block, a pull block and a wire groove, and ensure the stability of the silk thread during the twisting process, thereby improving the twisting quality and efficiency.

[0009] However, when the twisting device of the nylon stretch yarn in the above-mentioned cited document is used, in the existing nylon stretch yarn twisting device, a significant problem is that the yarn runs away during the twisting process, which directly affects the twisting effect and makes the twisting process lack stability and reliability. This is mainly due to the working principle of the twisting device and the characteristics of the nylon stretch yarn. Due to its unique molecular structure, the nylon stretch yarn has excellent elasticity and resilience, but it also means that when the yarn is subjected to external force, its molecular chain is prone to slip, resulting in the yarn being difficult to maintain stable tension during the twisting process. Once the yarn tension fluctuates and fails to be adjusted in time, it is easy to cause the yarn to run away, resulting in instability and reduced reliability of the twisting process.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 4 The utility model provides a technical solution: a nylon stretch yarn twisting device, comprising a mounting base 1, a working box 2, a wire device body 3, a twisting device body 4 and an adjusting device body 5, one side of the working box 2 is fixedly mounted on the side of the mounting base 1 away from the ground, the wire device body 3 passes through one side of the working box 2 and is fixedly connected to one side of the working box 2, the twisting device body 4 is fixedly mounted on an inner side wall of the working box 2 close to the mounting base 1, the adjusting device body 5 is fixedly mounted on the inner side wall of the working box 2 and its position corresponds to the twisting device body 4 one by one, and an anti-running wire mechanism 600 is installed on the adjusting device body 5;

[0032] By installing the working box 2, the wire device body 3, the twisting device body 4, the adjustment device body 5 and the anti-runaway mechanism 600 on the base 1, a function of preventing the position of the silk thread from shifting can be provided.

[0033] In this embodiment, the thread-missing prevention mechanism 600 is used to provide a structure for preventing the thread from shifting.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the anti-runaway mechanism 600 includes a clamping and regulating box 601 fixedly mounted on one side of the regulating device body 5 and two drive components respectively mounted in the clamping and regulating box 601 and in mirror symmetry, two adjusting moving blocks 603 in mirror symmetry are connected to the outer side of the drive component, two adjusting moving blocks 603 are respectively connected to one side with two hinge components in mirror symmetry, a limited moving component is connected between the two hinge components away from the adjusting moving blocks 603, and clamping stabilization components arranged equidistantly are installed on opposite sides of the two limited moving components;

[0035] Both left and right sides of the clamping and regulating box 601 are provided with movable holes 608 for the wire to pass through.

[0036] It should be noted that the drive assembly includes a bidirectional screw rod 6021, a turning handle 6022 and a bearing support 6023; one side of the bearing support 6023 is fixedly installed on the inner wall of the clamping and regulating box 601 by bolts, one end of the bidirectional screw rod 6021 passes through the two adjusting moving blocks 603 and extends to the inside of the bearing support 6023 and is rotatably connected to the bearing support 6023 through a bearing, and the other end passes through the clamping and regulating box 601 and extends to the outside of the clamping and regulating box 601 and is fixedly connected to the turning handle 6022, so that when the turning handle 6022 is rotated, the bidirectional screw rod 6021 can be driven to rotate to drive the two adjusting moving blocks 603 connected to the outside of the bidirectional screw rod 6021 to move.

[0037] It can be understood that a dividing block is fixedly connected to the center position of the bidirectional screw rod 6021, and the dividing block divides the bidirectional screw rod 6021 into a left half and a right half. The left half of the bidirectional screw rod 6021 is a left-handed thread, and the right half of the bidirectional screw rod 6021 is a right-handed thread. The two adjusting moving blocks 603 are respectively threadedly connected to the left half and the right half of the bidirectional screw rod 6021, and the two adjusting moving blocks 603 are mirror-symmetrical, so that when the bidirectional screw rod 6021 is driven to rotate, the two adjusting moving blocks 603 can be driven to move at a uniform speed in opposite directions at the same time.

[0038] In addition, the articulated assembly includes an articulated seat No. 1 6041, an articulated rod 6042 and an articulated seat No. 2 6043; one side of the articulated seat No. 1 6041 is connected to one side of the limiting movable assembly, one side of the articulated seat No. 2 6043 is fixedly connected to one side of the adjusting movable block 603, one end of the articulated rod 6042 is hinged to the inner side of the articulated seat No. 1 6041 through a pin shaft, and the other end of the articulated rod 6042 is hinged to the inner side of the articulated seat No. 2 6043 through a pin shaft, so as to be able to push the limiting movable assembly to move.

[0039] In this embodiment, the limit moving assembly includes a moving plate 6051 and two limit blocks 6052; one side of the two No. 1 hinge seats 6041 is fixedly connected to one side of the moving plate 6051, the outer side of the moving plate 6051 is slidably connected to the inner side of the clamping and regulating box 601 and slides in close contact with the clamping and regulating box 601, and the opposite sides of the two limit blocks 6052 are fixedly connected to the two sides of the moving plate 6051 respectively;

[0040] The inner wall of the clamping and regulating box 601 is provided with a limiting groove 606 for the limiting block 6052 to slide against, so as to improve the moving stability of the moving plate 6051 and limit the moving distance of the moving plate 6051.

[0041] It should also be noted that the clamping stabilization assembly includes a fixed connecting block 6071, a rotating support block 6072 and a rotating pressure roller 6073; one side of the fixed connecting block 6071 is fixedly installed on the side of the moving plate 6051 away from the adjusting moving block 603, and one side of the rotating support block 6072 is fixedly installed on the other side opposite to the fixed connecting block 6071 by bolts, and the number of rotating support blocks 6072 is two and they are distributed in a mirror-symmetrical manner, and the two ends of the rotating pressure roller 6073 are respectively rotatably connected on the opposite sides of the two rotating support blocks 6072, so that the surface of the silk thread will not be damaged by clamping, and its conveying speed and tension will not be affected, thereby effectively preventing the position of the silk thread from being offset.

[0042] The working principle of the above embodiment is:

[0043] When in use, first adjust the position of the clamping regulating box 601 through the adjusting device body 5, then pass the silk thread through the wire guide device body 3, the twisting device body 4 and the moving hole 608 and straighten it, then start the whole device, when it is necessary to prevent the silk thread from running away, first hold the turning handle 6022 and turn it, and under the rotating support of the bearing, the bidirectional screw rod 6021 is stably driven to rotate and at the same time drive the two adjusting moving blocks 603 to move at a uniform speed in opposite directions. Since the adjusting moving block 603 is connected to the No. 1 articulated seat 6041 articulated on the articulated rod 6042 through the No. 2 articulated seat 6043, the No. 2 articulated seat 6043 is driven along when the adjusting moving block 603 moves. The hinged seat 6041 is hinged to the other end of the hinged rod 6042. Therefore, when one end of the hinged rod 6042 moves horizontally, the other end is converted into vertical movement, and the movable plate 6051 is driven to move under the sliding connection between the limit block 6052 and the limit groove 606, so that the two rotating pressure rollers 6073 are close to each other and clamp the silk thread. When the silk thread moves, the rotating pressure roller 6073 and the rotating support block 6072 can follow the movement of the silk thread under the rotation connection, so as to ensure that the silk thread always remains on the correct path. This clamping method will not cause damage to the surface of the silk thread, nor will it affect its conveying speed and tension.

[0044] Compared with the prior art: the twisting device of the nylon stretch yarn can provide a function of preventing the position of the silk thread from shifting by using the working box 2, the wire device body 3, the twisting device body 4, the adjustment device body 5 and the anti-runaway mechanism 600 installed on the base 1 in coordination with each other, so as to effectively clamp the silk thread without affecting the normal conveying of the silk thread, ensuring that the silk thread always remains on the correct path. This clamping method will not cause damage to the surface of the silk thread, nor will it affect its conveying speed and tension. It not only effectively prevents the position of the silk thread from shifting, but also improves the stability and reliability of the conveying process, and solves the problem of the nylon stretch yarn running during the twisting process in the existing twisting device.
