Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, and specifically refers to a twisting machine. Background Technology

[0002] A twisting machine is a textile machinery device that twists multiple strands of fine yarn into one. Its function is to process yarn or combined yarn products into linear products for weaving and knitting. The twisting method for multi-ply yarns typically involves gradually increasing the number of plies until multiple plies are formed. This results in a larger machine with more mechanisms. Furthermore, because the number of plies is increased step by step, the twist applied to the yarn at different steps cannot be guaranteed to be completely consistent, leading to uneven yarn fineness and uneven twist distribution. This directly affects the yarn's luster, strength, and other quality issues.

[0003] To this end, the invention patent with application number 202011489598.7 discloses a yarn twisting device and a high-efficiency twisting machine, including a base frame. The top side of the base frame has a circular structure and a first gear is provided at its center. Multiple rotating shaft holes are evenly opened at the edge of the top side of the base frame. A central rotating shaft is rotatably installed in each of the multiple rotating shaft holes. A second gear and a rotating cylinder are sleeved on each of the multiple central rotating shafts. A first guide ring is provided on the top side of the base frame.

[0004] The aforementioned high-efficiency twisting machine uses a gear mechanism to enable multiple rotating drums to rotate synchronously and at the same speed along multiple central shafts. Different strands of yarn are fixedly installed in multiple rotating drums for rotational twisting, and then combined into a single yarn through a first guide ring. This achieves the effect of simultaneously twisting multiple strands of yarn with completely consistent twist, while effectively reducing the space occupied by the equipment.

[0005] However, the aforementioned twisting machines can only twist yarns and other relatively tough materials, and cannot twist metal wires. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a twisting machine that can twist metal wires.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A twisting machine includes a twisting mechanism, a yarn feeding mechanism, and a winding mechanism mounted on a frame. The twisting mechanism comprises a base, a rotating base, and a yarn tube. The yarn tube is fixed vertically to the upper side of the base. The base and the yarn tube have yarn holes through which they pass. A yarn spool can be placed below the base. The yarn tube can be inserted into the rotating base, which can rotate around the yarn tube. At least two metal spools are spaced circumferentially inside the rotating base. A [missing information - likely a design element] is positioned on the upper side of the rotating base opposite to the metal spools. A first guide hole for metal wires to pass through is provided on the upper side of the rotating seat, opposite to the yarn hole, and a second guide hole for yarns to pass through is provided on the upper side of the rotating seat. A wire clamp is provided on the upper side of the rotating seat, and a twisting plate is provided above the second guide hole. The twisting plate is provided with twisting holes. The yarn on the yarn spool passes through the yarn hole and the second guide hole in sequence. The metal wires on the metal spool pass through the first guide hole and the wire clamp in sequence, and merge with the yarns below the twisting plate to form a composite line. The composite line passes through the twisting holes and enters the winding mechanism through the wire feeding mechanism.

[0009] This twisting machine achieves the twisting of multiple metal wires onto a single yarn by rotating the entire rotating base around the yarn. This process also avoids the metal wires from curling or breaking due to their own rotation, thus achieving the twisting of the metal wires and resulting in a composite yarn with high structural strength. The design of the wire clamp and the wire feeding mechanism ensures that the metal wires are in a taut state when the twisting action is completed by rotating around the yarn, which helps to improve the quality of the composite yarn obtained after twisting.

[0010] The aforementioned metal wires are copper wires, aluminum wires, silver wires, or gold wires.

[0011] In the above-mentioned twisting machine, the wire clamp includes a mounting plate and a wire clamping body. The wire clamping body is fixed on the mounting plate, and the two sides of the mounting plate are bent upward to form positioning parts. The positioning parts are provided with wire passage holes.

[0012] The upward-bending positioning part and the wire-passing hole design can accurately guide the metal wire into the clamping body, effectively restrict the lateral displacement of the metal wire during the twisting process, and ensure that the metal wire always passes through the clamping device along the set path and tension. This further improves the reliability of the clamping device in stabilizing the tension of the metal wire, and ensures the twisting quality and the uniformity of the composite wire.

[0013] In the above-mentioned twisting machine, the rotating seat is provided with at least two spool boxes with upper openings, and a positioning post is provided in the middle of the spool box. The metal spool is placed in the spool box and can rotate around the positioning post. There is a thread passage gap between the edge of the metal spool and the inner wall of the spool box.

[0014] The spool box structure provides a stable and independent housing space for the metal spool. The positioning post ensures that the metal spool can rotate smoothly around its center to release the wire. The wire passage gap between the edge of the metal spool and the inner wall of the spool box provides a channel for the smooth exit of the metal wire, avoiding friction or jamming between the metal wire and the box wall when the wire is exited. This ensures the continuity and stability of the wire release during the twisting process, which is conducive to maintaining the uniformity of the twisting tension.

[0015] In the above-mentioned twisting machine, a bearing is sleeved on the outside of the yarn tube, the outer ring of the bearing is fixedly connected to the rotating seat, and a twisting drive is provided on the frame. The twisting drive is connected to the outer ring of the bearing and can drive the outer ring of the bearing to rotate.

[0016] The application of bearings significantly reduces the frictional resistance of the rotating seat relative to the fixed yarn tube, making the rotation of the rotating seat more stable, smooth, and energy-efficient. The twisting drive directly drives the outer ring of the bearing (i.e., the rotating seat) to rotate, and the power transmission is direct and efficient, ensuring that the rotating seat can obtain a stable and controllable speed, providing a reliable power foundation for the uniform and efficient twisting of metal wires around the yarn.

[0017] In the above-mentioned twisting machine, the wire feeding mechanism is located above the twisting mechanism. The wire feeding mechanism includes at least two wire feeding rollers. The frame is provided with a wire feeding drive unit that drives the wire feeding rollers to rotate. The wire feeding drive unit is connected to one of the wire feeding rollers. Adjacent wire feeding rollers are connected to each other by a pulley or belt.

[0018] The wire feeding mechanism is positioned above the twisting mechanism, allowing the composite wire to be smoothly pulled upwards into the winding mechanism after it is formed. The structure of multiple wire feeding rollers driven synchronously by pulleys / belts provides a stable and adjustable traction force, clamping and evenly conveying the twisted composite wire forward. This synchronous drive method ensures that the linear speed of each wire feeding roller is consistent, avoiding uneven stretching or damage to the composite wire, and ensuring the tension stability and integrity of the composite wire during the conveying process.

[0019] In the above-mentioned twisting machine, the wire feeding roller is provided with a plurality of wire feeding grooves spaced apart along the axial direction.

[0020] Multiple axially spaced wire feeding grooves allow the composite wire to wind several turns before adjacent wire feeding rollers, which helps increase the friction between the composite wire and the wire feeding rollers and ensures the stability of the wire feeding process. The wire feeding grooves also limit the composite wire, effectively preventing the adjacent composite wires from tangling or rubbing against each other, thus ensuring the order of conveying and product quality.

[0021] In the above-mentioned twisting machine, the winding mechanism includes a winding reel, a reel support, and a winding pressure roller. The winding reel is rotatably mounted on the reel support, and the lower end of the reel support is hinged to the frame. The winding pressure roller is rotatably mounted on the frame, and the frame is provided with a pressure roller drive component for driving the winding pressure roller to rotate. The winding reel can rotate downward around the hinge and abut against the outer circumferential surface of the winding pressure roller.

[0022] The hinged design at the lower end of the spool bracket, in conjunction with the winding pressure roller, allows for convenient adjustment of the contact pressure between the spool and the pressure roller (via the swing angle of the spool bracket). When the spool swings down against the rotating winding pressure roller, the rotational friction of the pressure roller drives the spool to rotate and wind up. This structure utilizes the friction of the pressure roller as the winding power, and the winding tension can be flexibly controlled by adjusting the swing angle (i.e., the contact pressure), ensuring that the composite yarn is wound evenly and tightly on the spool with appropriate tension, preventing tangles or damage caused by excessive looseness or tightness.

[0023] In the above-mentioned twisting machine, the winding mechanism includes an adjusting screw installed on the front side of the winding pressure roller. One end of the adjusting screw is connected to a screw drive component that drives the adjusting screw to rotate. A screw nut that cooperates with the adjusting screw is provided on the adjusting screw. A limiting rod that prevents the screw nut from rotating is provided on one side of the screw. A positioning plate is provided on the screw nut, and a positioning hole is provided on the positioning plate.

[0024] The adjusting screw, screw nut, limit rod, and positioning plate together constitute a precision yarn guiding traverse device. The screw drive drives the adjusting screw to rotate. Under the restriction of the limit rod, the screw nut can only move linearly along the screw axis, thereby driving the positioning plate and its positioning holes to move synchronously. The composite yarn passes through the positioning holes. Therefore, the translation of the positioning plate realizes the regular reciprocating traverse (yarn guiding) of the composite yarn in the width direction of the winding spool, ensuring that the composite yarn can be evenly and flatly spread across the entire width of the winding spool layer by layer, effectively avoiding poor winding phenomena such as overlapping and protruding edges, and improving the winding quality.

[0025] In the aforementioned twisting machine, two rollers are provided on the side wall of the lead screw nut, and the limiting rod is located between the two rollers.

[0026] Two rollers on the side wall of the lead screw nut form rolling contact with the limiting rod. This design transforms the sliding friction between the lead screw nut and the limiting rod into rolling friction, greatly reducing the frictional resistance between them. This makes the movement of the lead screw nut easier and smoother, reduces jamming and wear during the movement, improves the stability, accuracy and lifespan of the yarn guiding device, and further ensures the uniformity of winding.

[0027] Compared with the prior art, the technical effects of this utility model are as follows:

[0028] This invention achieves the twisting of multiple metal wires onto a single yarn by rotating the entire rotating seat around the yarn. This process also avoids the metal wires from curling or breaking due to their own rotation, thus achieving the twisting of the metal wires and resulting in a composite yarn with high structural strength. The design of the wire clamp and the wire feeding mechanism ensures that the metal wires are in a taut state when the twisting action is completed by rotating around the yarn, which is beneficial to improving the quality of the composite yarn obtained after twisting.

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0038] This twisting machine includes a twisting mechanism 1, a yarn feeding mechanism 2, and a winding mechanism 3 mounted on a frame 4. The twisting mechanism 1 includes a base 11, a rotating base 12, and a yarn tube 13. The yarn tube 13 is fixed vertically to the upper side of the base 11. The base 11 and the yarn tube 13 are provided with yarn holes 131 through which they pass. A yarn spool 111 can be placed below the base 11. The yarn tube 13 can be inserted into the rotating base 12, which can rotate around the yarn tube 13. At least two metal spools 14 are arranged circumferentially inside the rotating base 12. A metal wire is provided on the upper side of the rotating base 12 opposite to the metal spools 14 for the metal wire to pass through. The first guide hole 121 and the second guide hole 122, which are located on the upper side of the rotating seat 12 opposite to the yarn hole 131, are provided for the yarn to pass through. A wire clamp 15 is provided on the upper side of the rotating seat 12. A twisting plate 16 is provided above the second guide hole 122. A twisting hole 161 is provided on the twisting plate 16. The yarn of the yarn spool 111 passes through the yarn hole 131 and the second guide hole 122 in sequence. The metal wire on the metal spool 14 passes through the first guide hole 121 and the wire clamp 15 in sequence, and merges with the yarn below the twisting plate 16 to form a composite line. The composite line passes through the twisting hole 161 and enters the winding mechanism 3 through the wire feeding mechanism 2.

[0039] This twisting machine achieves the twisting of multiple metal wires onto a single yarn by rotating the rotating base 12 around the yarn. This process also avoids the metal wires from curling or breaking due to their own rotation, thus achieving the desired twisting of the metal wires and resulting in a composite yarn with high structural strength. The design of the wire clamp 15 in conjunction with the wire feeding mechanism 2 ensures that the metal wires are in a taut state during the twisting process, which helps improve the quality of the resulting composite yarn. The aforementioned metal wires can be copper, aluminum, silver, or gold.

[0040] like Figure 7 As shown, the wire clamp 15 includes a mounting plate 151 and a clamping body 152. The clamping body 152 is fixed to the mounting plate 151. The two sides of the mounting plate 151 are bent upward to form positioning portions 1511, and the positioning portions 1511 are provided with wire-passing holes 1512. The design of the upwardly bent positioning portions 1511 and the wire-passing holes 1512 can accurately guide the metal wire into the clamping body 152, effectively limit the lateral displacement of the metal wire during the twisting process, and ensure that the metal wire always passes through the wire clamp 15 with a set path and tension. This further improves the reliability of the wire clamp 15 in stabilizing the tension of the metal wire, and ensures the twisting quality and the uniformity of the composite yarn.

[0041] like Figure 5As shown, the rotating base 12 has at least two spool boxes 17 with openings on the upper side. A positioning post 171 is provided in the middle of the spool box. The metal spool 14 is placed in the spool box 17 and can rotate around the positioning post 171. There is a wire passage gap between the edge of the metal spool 14 and the inner wall of the spool box 17. The structure of the spool box 17 provides a stable and independent housing space for the metal spool 14. The positioning post 171 ensures that the metal spool 14 can rotate smoothly around its center to release the wire. The wire passage gap between the edge of the metal spool 14 and the inner wall of the spool box 17 provides a channel for the smooth exit of the metal wire, avoiding friction or jamming between the metal wire and the box wall when the wire is exited. This ensures the continuity and stability of the wire release during the twisting process, thereby helping to maintain the uniformity of the twisting tension.

[0042] like Figure 3 As shown, a bearing 132 is sleeved on the outer side of the yarn tube 13. The outer ring of the bearing 132 is fixedly connected to the rotating seat 12. A twisting drive 18 is provided on the frame 4. The twisting drive 18 is connected to the outer ring of the bearing 132 and can drive the outer ring of the bearing 132 to rotate. The application of the bearing 132 significantly reduces the frictional resistance of the rotating seat 12 relative to the fixed yarn tube 13, making the rotation of the rotating seat 12 more stable, smooth, and energy-efficient. The twisting drive 18 directly drives the outer ring of the bearing 132 (i.e., the rotating seat 12) to rotate, and the power transmission is direct and efficient, ensuring that the rotating seat 12 can obtain a stable and controllable speed, providing a reliable power basis for the uniform and efficient twisting of the metal wire around the yarn.

[0043] like Figure 1-4 As shown, the wire feeding mechanism 2 is located above the twisting mechanism. The wire feeding mechanism 2 includes at least two wire feeding rollers 21. A wire feeding drive unit 22 is provided on the frame 4 to drive the wire feeding rollers 21 to rotate. The wire feeding drive unit 22 is connected to one of the wire feeding rollers. Adjacent wire feeding rollers 21 are connected by pulleys or belts. Several wire feeding grooves 211 are provided on the wire feeding rollers 21 at intervals along the axial direction. The wire feeding mechanism 2 is positioned above the twisting mechanism 1, allowing the composite wire to be smoothly pulled upwards into the winding mechanism 3 after it is formed. The structure employs multiple wire feeding rollers 21 driven synchronously by pulleys / belts, providing stable and adjustable traction force. This clamps and evenly feeds the twisted composite wire forward. This synchronous drive ensures that the linear speed of each wire feeding roller 21 is consistent, avoiding uneven stretching or damage to the composite wire and ensuring the tension stability and integrity of the composite wire during transport. Multiple axially spaced wire feeding grooves 211 allow the composite wire to wind several turns before adjacent wire feeding rollers 21, increasing the friction between the composite wire and the wire feeding rollers 21 and ensuring stability during the wire feeding process. The wire feeding grooves 211 also limit the movement of the composite wire, effectively preventing entanglement or friction between adjacent composite wires, ensuring order and product quality during transport.

[0044] Furthermore, the winding mechanism 3 includes a winding spool 31, a spool support 32, and a winding pressure roller 33. The winding spool 31 is rotatably mounted on the spool support 32, and the lower end of the spool support 32 is hinged to the frame 4. The winding pressure roller 33 is rotatably mounted on the frame 4, and the frame 4 is provided with a pressure roller drive 34 for driving the winding pressure roller 33 to rotate. The winding spool 31 can rotate downward around the hinge and abut against the outer peripheral surface of the winding pressure roller 33. The hinged design at the lower end of the spool bracket 32, in conjunction with the winding pressure roller 33, enables convenient adjustment of the contact pressure between the winding spool 31 and the pressure roller (by adjusting the swing angle of the spool bracket 32). When the winding spool 31 swings down against the rotating winding pressure roller 33, the rotational friction of the pressure roller drives the winding spool 31 to rotate and wind up. This structure utilizes the friction of the pressure roller as the winding power and can flexibly control the winding tension by adjusting the swing angle (i.e., the contact pressure), ensuring that the composite yarn can be wound evenly and tightly on the winding spool 31 with appropriate tension, preventing tangles or damage caused by excessive looseness or tightness.

[0045] like Figure 1-4 and Figure 6 The locking and winding mechanism 3 includes an adjusting screw 35 installed on the front side of the winding pressure roller 33. One end of the adjusting screw 35 is connected to a screw drive 36 that drives the adjusting screw 35 to rotate. A screw nut 37 that cooperates with the adjusting screw 35 is provided on the adjusting screw 35. A limiting rod 38 that prevents the screw nut 37 from rotating is provided on one side of the screw. A positioning plate 371 is provided on the screw nut 37, and a positioning hole 372 is provided on the positioning plate 371. Two rollers 39 are provided on the side wall of the screw nut 37, and the limiting rod 38 is located between the two rollers 39.

[0046] The adjusting screw 35, screw nut 37, limiting rod 38, and positioning plate 371 together constitute a precision yarn guiding traverse device. The screw drive 36 drives the adjusting screw 35 to rotate. Under the restriction of the limiting rod 38, the screw nut 37 can only move linearly along the screw axis, thereby driving the positioning plate 371 and its positioning hole 372 to move synchronously. The composite yarn passes through the positioning hole 372. Therefore, the translation of the positioning plate 371 realizes the regular reciprocating traverse (yarn guiding) of the composite yarn in the width direction of the winding reel 31, ensuring that the composite yarn can be laid evenly and flatly layer by layer. The entire width of the winding reel 31 is filled, effectively avoiding undesirable winding phenomena such as overlapping and protruding edges, thus improving winding quality. The two rollers 39 set on the side wall of the lead screw nut 37 form rolling contact with the limiting rod 38. This design transforms the sliding friction between the lead screw nut 37 and the limiting rod 38 into rolling friction, greatly reducing the frictional resistance between the two. This makes the movement of the lead screw nut 37 easier and smoother, reducing jamming and wear during the movement process, improving the stability, accuracy and lifespan of the yarn guiding traverse device, and further ensuring the uniformity of winding.

[0047] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection defined by the claims of the present utility model.
