Description

Technical Field

[0001] This invention belongs to the field of twisting machine technology, specifically relating to a one-step horizontal twisting machine. Background Technology

[0002] A twisting machine is a textile machinery device that twists multiple strands of fine yarn into a single strand. Its function is to process yarn or combined yarn products into linear products for weaving and knitting. Existing twisting machines consist of a primary twisting unit and a secondary twisting unit. The primary twisting unit often adopts a vertical arrangement, with the unwinding bobbin vertically mounted on the primary twisting unit for yarn unwinding and twisting. However, for double-conical unwinding bobbins, this type of primary twisting equipment has certain drawbacks. Specifically, because the double-conical bobbin has conical structures at both ends, the yarn is continuously subjected to axial force during unwinding. Under high-speed operation, the yarn is prone to slipping and unwinding along the conical surfaces at both ends, resulting in yarn slippage and disorder, which in turn leads to frequent yarn breakage, seriously affecting production efficiency and yarn quality.

[0003] In addition, retwisting equipment is equipped with roller units that work in conjunction with the retwisting unit to pull the yarn. In existing semi-automatic roller assemblies (i.e., one drive motor drives multiple roller units to work synchronously through the same main drive shaft), if there is a problem with the yarn in the primary twisting unit, retwisting unit, or corresponding unit of any roller unit, the entire twisting machine needs to be stopped for inspection and maintenance, which directly affects the processing efficiency of the twisting equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a one-step horizontal twisting machine to solve the problem of low processing efficiency of twisting machines.

[0005] The one-step horizontal twisting machine of the present invention is implemented as follows: One-step horizontal twisting machine, including A primary twisting device includes multiple primary twisting mechanisms arranged side by side. Each primary twisting mechanism includes at least one row of primary twisting units. Each row of primary twisting units includes several primary twisting units arranged longitudinally. The primary twisting units are arranged horizontally. Each primary twisting unit includes a main shaft, a turntable mounted on the main shaft and capable of rotating synchronously with the main shaft, and a suspension base mounted on the front end of the main shaft and rotatably cooperating with the main shaft. The retwisting device includes retwisting mechanisms arranged one-to-one with the initial twisting mechanism. Each retwisting mechanism includes retwisting units arranged corresponding to the initial twisting unit row, and roller units arranged corresponding to the retwisting units. Each roller unit includes a traction wheel and a clutch assembly. Any roller unit can be separated from the main drive shaft of the retwisting device through the corresponding clutch assembly.

[0006] Furthermore, the initial twisting unit also includes a front guide tube, a bobbin body, and a rear guide tube arranged sequentially from front to back, as well as a guide disc located on the rear side of the turntable and fixedly connected thereto. The front guide tube, bobbin body, rear guide tube, main shaft, and guide disc are sequentially connected to form an L-shaped yarn feeding channel. The rear yarn guide tube is installed on the front side of the suspension base; The outer side of the rear yarn guide tube is fitted with a support bushing; An axially arranged arc-shaped retaining spring is installed on the outer side of the liner body. The front guide tube is provided with a rearwardly extending front guide bobbin on its outside, and the front guide bobbin is provided with a yarn withdrawal hole on its side wall. The rear edge of the leading yarn bobbin is provided with a first initial twist air ring; The leading yarn bobbin is a conical cylinder.

[0007] Furthermore, a bearing housing is installed at the front end of the main rotating shaft, and the suspension base is connected to the main rotating shaft through the bearing housing; A counterweight is provided at the bottom of the suspension base; The bearing housing is provided with a rear guide yarn bobbin located outside the suspension base and extending forward; The rear guide yarn tube is a cylindrical body.

[0008] Furthermore, each main shaft of the same initial twisting unit is connected to the same initial twisting motor drive; The initial twisting motor is located at the bottom of the corresponding initial twisting unit column.

[0009] Furthermore, each initial twisting unit is equipped with a yarn breakage alarm unit.

[0010] Furthermore, the clutch assembly includes a main clutch gear and a secondary clutch gear. The main clutch gear is connected to the main drive shaft, and the secondary clutch gear is equipped with a main drive wheel that is connected to the traction wheel. When the main clutch gear and the secondary clutch gear mesh, the main drive shaft drives the traction wheel to rotate.

[0011] Furthermore, the clutch assembly also includes a cylinder, a lever connected at the upper end to the piston rod of the cylinder, and a support rod hinged to the middle of the lever. The lower end of the lever engages with the main clutch gear. When the piston rod of the cylinder extends or retracts, the lever can rotate relative to the support rod and drive the main clutch gear to move toward or away from the secondary clutch gear. The lever is a Y-shaped lever fork, with its two side lugs respectively fitting into the annular grooves on the outer ring surface of the main clutch gear; The inner side of each ear plate is equipped with a cam that mates with the annular groove.

[0012] Furthermore, the traction wheel is provided with two pulleys, each of which is connected to a driven pulley, and the driven pulley is connected to the main drive wheel for transmission.

[0013] Furthermore, the main drive shaft is arranged laterally above the retwisting device and cooperates with the clutch assembly of each roller unit, and the main drive shaft is connected to a drive motor.

[0014] Furthermore, the retwisting unit includes a retwisting spindle, a retwisting motor for driving the retwisting spindle to rotate, and a steel collar disposed around the retwisting spindle and capable of being raised and lowered.

[0015] After adopting the above technical solution, the beneficial effects of the present invention are as follows: (1) The present invention sets the initial twisting unit as a horizontal structure, so that the double conical yarn bobbin is arranged horizontally, which can overcome the defect that the yarn is easy to slip and fall off along the conical surface when arranged vertically, reduce yarn tangling and breakage, and improve the initial twisting efficiency while ensuring the yarn forming quality. (2) By setting a clutch unit in the roller unit, the present invention can realize the transmission connection or separation of any roller unit and the main drive shaft. That is, when any roller unit or its corresponding twisting unit fails, the roller unit can be stopped and repaired separately through the clutch assembly, without affecting the normal operation of other roller units, thus ensuring the processing efficiency of the twisting equipment.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0020] like Figure 1-15 As shown, a one-step horizontal twisting machine includes a primary twisting device 1 and a secondary twisting device 2. The primary twisting device 1 includes multiple primary twisting mechanisms 1-1 arranged side by side. Each primary twisting mechanism 1-1 includes at least one row of primary twisting units 1-11. Each row of primary twisting units 1-11 includes several primary twisting units 1-11 arranged longitudinally. The primary twisting units 1-11 are arranged horizontally. Each primary twisting unit 1-11 includes a main rotating shaft 1-11-1, a turntable 1-11-2 mounted on the main rotating shaft 1-11-1 and capable of rotating synchronously with the main rotating shaft 1-11-1, and a turntable 1-11-2 mounted on the main rotating shaft 1-11-1. The suspension base 1-11-3 at the front end of the rotating shaft 1-11-1 and rotatingly engaged with the main rotating shaft 1-11-1; the retwisting device 2 includes a retwisting mechanism 2-1 arranged in a one-to-one correspondence with the initial twisting mechanism 1-1. The retwisting mechanism 2-1 includes a retwisting unit 2-11 arranged in a row corresponding to the initial twisting unit 1-11, and a roller unit 2-12 arranged in a corresponding manner to the retwisting unit 2-11. The roller unit 2-12 includes a traction wheel and a clutch assembly. Any roller unit 2-12 can be separated from the main drive shaft 2-2 of the retwisting device 2 through the corresponding clutch assembly.

[0021] The unwinding bobbin 3 in this embodiment uses a double-conical bobbin, but it is not only applicable to this type of bobbin.

[0022] Specifically, the unwinding bobbin 3 is placed on the initial twisting unit 1-11, and the initial twisting operation is performed using the initial twisting device 1. Then, it enters the re-twisting device 2 for re-twisting operation, and finally, it is wound onto the winding bobbin (placed on the re-twisting unit 2-11).

[0023] In this embodiment, the initial twisting device 1 includes six initial twisting mechanisms 1-1 arranged side by side. Each initial twisting mechanism 1-1 contains two rows of initial twisting units 1-11 (i.e., two rows of initial twisting units 1-11). Each row of initial twisting units 1-11 has three initial twisting units 1-11 arranged longitudinally. Therefore, during retwisting, the three strands of yarn on the three initial twisting units 1-11 in the same row are retwisted into one strand. Correspondingly, the retwisting device 2 includes six retwisting mechanisms 2-1 arranged side by side (one-to-one with the initial twisting mechanisms 1-1). Each retwisting mechanism 2-1 has two retwisting units 2-11 arranged side by side (one-to-one with the two rows of initial twisting units 1-11).

[0024] In this embodiment, the six initial twisting mechanisms 1-1 are installed on the same initial twisting base 1-2 in groups of three, and the retwisting mechanisms 2-1 are also arranged in groups of three. A control box 2-3 corresponding to the retwisting device 2 is provided between the two groups of retwisting mechanisms 2-1.

[0025] The initial twisting mechanism 1-1 includes an initial twisting frame 1-12 for mounting the initial twisting units 1-11. Two rows of initial twisting units 1-11 within the same initial twisting mechanism 1-1 are separated by partitions 1-12-5 and 1-12-51-13 to prevent interference. Sealing plates 1-12-1 are installed on both sides and the top of the initial twisting frame 1-12 to prevent airflow from affecting the yarn direction. Openable maintenance doors 1-12-2 are installed at the sealing plates 1-12-1 on both sides of the initial twisting mechanism 1-1, facilitating maintenance of the rows of initial twisting units 1-11 on their respective sides. A passageway is provided between adjacent initial twisting mechanisms 1-1 for maintenance personnel to pass through.

[0026] In the initial twisting mechanism 1-1, the main rotating shaft 1-11-1 is rotatably mounted on the initial twisting frame 1-12 via the bearing sleeve 1-11-4. The turntable 1-11-2 is directly fixed to the main rotating shaft 1-11-1 via the flange 1-11-5. It can rotate synchronously with the main rotating shaft 1-11-1. The yarn unwound from the unwinding bobbin 3 can pass through a fixed position on the outer ring surface of the turntable 1-11-2 to guide the yarn.

[0027] To achieve precise yarn guidance, turntable 1-11-2 includes a vertically arranged inner disc, an inclined disc located around the inner disc with its outer edge tilted forward, and an outer disc ring located at the outer edge of the inclined disc and extending forward. The design of turntable 1-11-2 constrains the yarn path, balances yarn tension, reduces the probability of friction between the yarn and components, minimizes yarn fuzzing and damage, and ensures yarn processing quality.

[0028] In this embodiment, the turntable 1-11-2 is an integral structure. The inner disc can be easily matched with the yarn guide disc 1-11-9, and the inclined disc and outer disc can accurately guide the yarn.

[0029] To reduce friction on the yarn, the outer wall at the junction of the inclined disc and the outer disc ring is curved.

[0030] In order to provide a yarn path, the initial twisting unit 1-11 also includes a front guide tube 1-11-6, a bobbin body 1-11-7 and a rear guide tube 1-11-8 arranged from front to back, and a guide plate 1-11-9 set behind the turntable 1-11-2 and fixedly connected to it. The front guide tube 1-11-6, the bobbin body 1-11-7, the rear guide tube 1-11-8, the main rotating shaft 1-11-1 and the guide plate 1-11-9 are connected in sequence to form an L-shaped yarn path.

[0031] The front guide tube 1-11-6 is installed at the front end of the liner body 1-11-7. The two are internally connected to form a straight yarn feeding channel. The rear guide tube 1-11-8 is coaxially arranged with the liner body 1-11-7 and the main shaft 1-11-1 respectively. After the yarn passes through the yarn feeding channel, it enters the rear guide tube 1-11-8.

[0032] The yarn guide plate 1-11-9 is closely attached to the rear side of the turntable 1-11-2. The two are fixed to the main rotating shaft 1-11-1 by the same flange 1-11-5 located on the rear side of the yarn guide plate 1-11-9. The yarn guide plate 1-11-9 is provided with a yarn outlet hole located in its radial direction. The main rotating shaft 1-11-1 is provided with a radial hole opposite to the yarn outlet hole. The radial hole is provided with an axial core hole extending to the front end of the main rotating shaft 1-11-1. The axial core hole, the radial hole and the yarn outlet hole are connected in sequence to form an L-shaped yarn outlet channel.

[0033] In order to ensure that the yarn can turn from the radial hole and directly enter the yarn outlet hole, a turning block 1-11-10 is provided in the radial hole, so that the yarn can only enter the yarn outlet hole through the inner hole of the turning block 1-11-10.

[0034] The yarn inlet channel, the rear yarn guide tube 1-11-8, and the yarn outlet channel form a complete yarn path. The yarn unwound from the unwinding bobbin 3 enters from the front yarn guide tube 1-11-6, then passes through the spindle body 1-11-7, the rear yarn guide tube 1-11-8, and the main shaft 1-11-1 in sequence, and finally exits from the side of the yarn guide plate 1-11-9.

[0035] Preferably, in order to facilitate the entry of the yarn into the yarn feeding channel, a yarn guide head 1-11-11 is installed at the front end of the pre-guide yarn tube 1-11-6.

[0036] To secure the rear guide tube 1-11-8, the rear guide tube 1-11-8 is installed on the front side of the suspension base 1-11-3.

[0037] When the main shaft 1-11-1 rotates, the suspension base 1-11-3 will not rotate with it, and the corresponding rear guide tube 1-11-8 will also not rotate with the main shaft 1-11-1.

[0038] To facilitate the placement of the unwinding bobbin 3, a support bushing 1-11-12 is fitted over the rear guide tube 1-11-8. The unwinding bobbin 3 is placed outside the support bushing 1-11-12 and can rotate relative to the support bushing 1-11-12. The rotation of the main shaft 1-11-1 can drive the yarn to move, causing the yarn to be passively unwound from the unwinding bobbin 3, thereby causing the unwinding bobbin 3 to passively rotate around the main shaft 1-11-1 outside the support bushing 1-11-12.

[0039] After the unwinding bobbin 3 is placed on the support bushing 1-11-12, the bobbin body 1-11-7 is assembled on the front end of the unwinding bobbin 3. In order to ensure the stability of the two, an axially arranged arc-shaped retaining spring 1-11-13 is installed on the outside of the bobbin body 1-11-7.

[0040] In this embodiment, multiple arc-shaped retaining springs 1-11-13 are assembled around the main body 1-11-7. The outer arc surface of the arc-shaped retaining springs 1-11-13 abuts against the inner wall of the yarn tube to ensure the stability of the cooperation between the two.

[0041] To facilitate the unwinding of the yarn from the yarn bobbin, a rearwardly extending front yarn bobbin 1-11-14 is provided on the outside of the front yarn tube 1-11-16, and a yarn unwinding hole 1-11-13 is provided on the side wall of the front yarn bobbin 1-11-14.

[0042] The front guide yarn bobbin 1-11-14 covers the outside of the front conical part of the unwinding yarn bobbin 3. The yarn is output from the inside to the outside through the unwinding hole 1-11-13, and then conveyed forward to enter the yarn feeding channel from the guide head 1-11-11.

[0043] In this embodiment, the lead yarn tube 1-11-6 is connected to the lead yarn bobbin 1-11-14 via the connecting seat 1-11-16. Specifically, the lead yarn tube 1-11-6 is inserted and fixed inside the connecting seat 1-11-16, while the front end of the lead yarn bobbin 1-11-14 is fixed to the flange surface of the connecting seat 1-11-16 by bolts.

[0044] The rear edge of the leading yarn bobbin 1-11-14 is provided with a first initial twist air ring 1-11-17. The first initial twist air ring 1-11-17 can prevent the yarn from shifting outward during the unwinding process and ensure that it can smoothly enter the unwinding hole 1-11-13.

[0045] In order to fit with the conical part at the front end of the unwinding bobbin 3, the lead bobbin 1-11-14 is a conical cylinder.

[0046] The front guide yarn cylinder 1-11-14 is a conical cylinder that is smaller at the front and larger at the back. It can not only match the conical part at the front end of the unwinding yarn cylinder 3, but also allow the yarn to enter the yarn feeding channel along the outer wall of the front guide yarn cylinder 1-11-14, further improving the guiding effect on the yarn.

[0047] Preferably, to prevent the yarn from shifting outward, a second initial twisting air ring 1-11-18 is provided on the rear side of the first initial twisting air ring 1-11-17. The second initial twisting air rings 1-11-18 of the two initial twisting units 1-11 in the same horizontal direction are fixed on the same mounting plate 1-12-3 above them, and the two ends of the mounting plate 1-12-3 are fixed on the initial twisting frame 1-12. During the initial twisting process, the yarn is unwound from the unwinding bobbin 3, passes through the inside of the first initial twisting air ring 1-11-17 and exits from the inside out through the unwinding hole 1-11-13, and then enters the yarn inlet channel. The yarn output from the yarn outlet channel passes through the inside of the second initial twisting air ring 1-11-18 and then enters the next step.

[0048] In order to prevent the suspension base 1-11-3 from rotating with the main shaft 1-11-1, a bearing housing 1-11-19 is installed at the front end of the main shaft 1-11-1. The suspension base 1-11-3 is connected to the main shaft 1-11-1 through the bearing housing 1-11-19.

[0049] Specifically, the front end of the main shaft 1-11-1 passes through the inner ring of the bearing housing 1-11-19, and the suspension base 1-11-3 is fitted onto the outer ring of the bearing housing 1-11-19 and fixedly connected thereto.

[0050] To ensure the stability of the suspension base 1-11-3, a counterweight 1-11-20 is installed at the bottom of the suspension base 1-11-3. The counterweight 1-11-20 is installed so that the suspension base 1-11-3 is in a natural downward state when the main shaft 1-11-1 rotates, reducing the impact of the rotation of the main shaft 1-11-1 on it.

[0051] To ensure the guiding effect on the yarn, a rear guide yarn bobbin 1-11-21 is provided on the bearing housing 1-11-19, which is located outside the suspension base 1-11-3 and extends forward.

[0052] The rear guide bobbin 1-11-21 is a cylindrical body with its rear end face fixed on the bearing seat 1-11-19. Its front end extends forward and covers the outside of the tapered part of the rear end of the unwinding bobbin 3. This can prevent the yarn from deflecting inward after passing the turntable 1-11-2 and avoid mutual interference with the yarn in the tapered part of the rear end of the unwinding bobbin 3.

[0053] In this embodiment, the rear guide yarn cylinder 1-11-21 is a cylindrical body, which can ensure the guiding effect on the yarn.

[0054] In order to provide power for the rotation of the main shaft 1-11-1, each main shaft 1-11-1 in the same initial twisting unit 1-11 column is connected to the same initial twisting motor 1-14.

[0055] The rear end of the main shaft 1-11-1 is connected to the initial twisting motor 1-14 via a transmission belt (not shown in the figure). Specifically, in this embodiment, the rear ends of the main shafts 1-11-1 of the three units in the same initial twisting unit 1-11 column are respectively equipped with transmission pulleys 1-11-22 located behind the initial twisting mechanism 1-1. The output end of the initial twisting motor 1-14 is equipped with a drive pulley 1-14-1. The drive pulley 1-14-1 is connected to the adjacent transmission pulley 1-11-22 via a transmission belt. Then, the corresponding transmission pulleys 1-11-22 of the three main shafts 1-11-1 are connected in sequence via transmission belts, so that one initial twisting motor 1-14 can synchronously drive the main shafts 1-11-1 of the three initial twisting units 1-11 to rotate synchronously.

[0056] Preferably, a transmission box 1-12-4 is provided on the rear side of the frame, and the drive pulley 1-14-1, the transmission pulley 1-11-22 and the transmission belt are all located inside the transmission box 1-12-4.

[0057] For ease of installation and maintenance, the primary twisting motor 1-14 is located at the bottom of the corresponding primary twisting unit 1-11 column.

[0058] The primary twisting motor 1-14 is installed at the bottom of the primary twisting frame 1-12. Specifically, the primary twisting motor 1-14 is fixed on a mounting plate 1-14-2. One end of the mounting plate 1-14-2 is hinged to the primary twisting frame 1-12, and the other end is provided with an adjusting screw 1-14-3. The height of the primary twisting motor 1-14 can be adjusted by adjusting the screw 1-14-3.

[0059] The system can promptly alarm when yarn breaks. Each initial twisting unit 1-11 is equipped with a corresponding yarn breakage alarm unit 1-13.

[0060] The yarn breakage alarm unit 1-13 is installed on the initial twisting frame 1-12 in front of the corresponding initial twisting unit 1-11. The yarn breakage alarm unit 1-13 includes a yarn guide plate 1-13-1, a fixed yarn guide wheel 1-13-2, a tension yarn guide wheel 1-13-3, and a U-shaped frame 1-13-4. The swing arm of the tension yarn guide wheel 1-13-3 passes through the U-shaped frame 1-13-4. After passing through the yarn guide plate 1-13-1, the yarn passes over the fixed yarn guide wheel 1-13-2 and then under the tension yarn guide wheel 1-13-3.

[0061] During normal operation, the swing arm moves within the U-shaped frame 1-13-4. When a yarn breakage occurs, the yarn comes off the tension guide wheel 1-13-3, and the swing arm swings downward under its own weight and the weight of the tension guide wheel 1-13-3 until it rests at the bottom of the U-shaped frame 1-13-4. At this time, the alarm at the inner end of the tension shaft where the swing arm is located is activated to sound an alarm and promptly remind the staff that a yarn breakage has occurred.

[0062] In the retwisting device 2, the main drive shaft 2-2 provides power to the traction wheels of all roller units 2-12. In order to realize the independent stopping function of any traction wheel, the clutch assembly includes a main clutch gear 2-12-1 and a secondary clutch gear 2-12-2. The main clutch gear 2-12-1 is connected to the main drive shaft 2-2, and the secondary clutch gear 2-12-2 is equipped with a main drive wheel 2-12-3 that is connected to the traction wheel. When the main clutch gear 2-12-1 and the secondary clutch gear 2-12-2 mesh, the main drive shaft 2-2 drives the traction wheel to rotate.

[0063] In this embodiment, the main drive shaft 2-2 passes through the main clutch gear 2-12-1, the secondary clutch gear 2-12-2 and the main drive wheel 2-12-3 respectively. The main drive shaft 2-2 is connected to the main clutch gear 2-12-1 by a key (not shown in the figure), and the main drive shaft 2-2 can drive the main clutch gear 2-12-1 to rotate synchronously with it.

[0064] Specifically, an inner keyway 2-12-4 is provided on the inner ring surface of the main clutch gear 2-12-1, and an outer keyway 2-12-5 that mates with the inner keyway 2-12-4 is provided on the outer ring surface of the main drive shaft 2-2. The key is assembled in the outer keyway 2-12-5 and the inner keyway 2-12-4 to realize the transmission connection between the main drive shaft 2-2 and the main clutch gear 2-12-1.

[0065] The secondary clutch gear 2-12-2 and the main drive wheel 2-12-3 are loosely fitted on the main drive shaft 2-2. The main drive shaft 2-2 rotates independently, and there is no direct torque transmission between them. The secondary clutch gear 2-12-2 and the main drive wheel 2-12-3 can rotate freely relative to the main drive shaft 2-2. At the same time, the secondary clutch gear 2-12-2 and the main drive wheel 2-12-3 are fixedly connected and move synchronously.

[0066] Specifically, a connecting flange is provided on the outer ring surface of the secondary clutch gear 2-12-2, and the main drive wheel 2-12-3 is connected to the connecting flange and the two are fixed together by bolts. Since the traction wheel is connected to the main drive wheel 2-12-3, when the secondary clutch gear 2-12-2 rotates, the main drive wheel 2-12-3 can rotate synchronously with it, and the traction wheel performs the traction work of the yarn under the drive of the main drive wheel 2-12-31.

[0067] In order to achieve the engagement or disengagement of the main clutch gear 2-12-1 and the secondary clutch gear 2-12-2, the opposite end faces of the main clutch gear 2-12-1 and the secondary clutch gear 2-12-2 are mutually mating tooth surfaces, and the main clutch gear 2-12-1 can move toward or away from the secondary clutch gear 2-12-2.

[0068] When the main clutch gear 2-12-1 moves toward the secondary clutch gear 2-12-2 to engage the tooth surfaces of their opposite ends, the secondary clutch gear 2-12-2 will rotate with the main clutch gear 2-12-1 under the drive of the main drive shaft 2-2, meaning the entire roller unit 2-12 will work normally. When the main clutch gear 2-12-1 moves away from the secondary clutch gear 2-12-2 to disengage the tooth surfaces of their opposite ends, the secondary clutch gear 2-12-2 will not rotate with the main clutch gear 2-12-1, meaning the entire roller unit 2-12 will stop working.

[0069] In order to drive the main clutch gear 2-12-1 to move relative to the secondary clutch gear 2-12-2, the clutch assembly also includes a cylinder 2-12-6, a lever 2-12-7 whose upper end is connected to the piston rod of the cylinder 2-12-6, and a support rod 2-12-8 hinged to the middle of the lever 2-12-7. The lower end of the lever 2-12-7 engages with the main clutch gear 2-12-1. When the piston rod of the cylinder 2-12-6 extends or retracts, the lever 2-12-7 can rotate relative to the support rod 2-12-8 and drive the main clutch gear 2-12-1 to move toward or away from the secondary clutch gear 2-12-2.

[0070] In this embodiment, both the support rod 2-12-8 and the cylinder 2-12-6 are arranged laterally, that is, parallel to the main drive shaft 2-2 and arranged sequentially above the main drive shaft 2-2. The support rod 2-12-8 is a laterally arranged Y-shaped fork structure. The upper end of the lever 2-12-7 is adjacent to the piston rod of the cylinder 2-12-6, and the middle part passes through the two fork lugs on both sides of the support rod 2-12-8 and is rotatably coupled to the rotating pin (not shown in the figure) connected between the two fork lugs. The lower end of the lever 2-12-7 is engaged with the main clutch gear 2-12-1.

[0071] When the piston rod of cylinder 2-12-6 extends, the lever 2-12-7 rotates relative to the rotating pin to drive the main clutch gear 2-12-1 to move closer to the secondary clutch gear 2-12-2. When the piston rod of cylinder 2-12-6 retracts, the lever 2-12-7 rotates relative to the rotating pin to drive the main clutch gear 2-12-1 to move away from the secondary clutch gear 2-12-2.

[0072] In order to achieve the engagement between lever 2-12-7 and main clutch gear 2-12-1, lever 2-12-7 is a Y-shaped lever fork, with its two side lugs respectively engaging in the annular groove 2-12-9 on the outer ring surface of main clutch gear 2-12-1.

[0073] In this embodiment, the upper end of the handle of the Y-shaped shift fork is connected to the piston rod of the cylinder 2-12-6, the middle of the handle is hinged to the rotating pin on the support rod 2-12-8, and the two side ear plates are assembled in the annular groove 2-12-9.

[0074] Cams 2-12-10, which mate with ring grooves 2-12-9, are installed on the inner side of the ear plates. Cams 2-12-10 are fitted onto the inner side of the Y-type shift fork ear plates and mate within ring grooves 2-12-9. The design of cams 2-12-10 not only drives the main clutch gear 2-12-1 to move, but also reduces friction when they contact the main clutch gear 2-12-1, thus reducing the probability of damage to the clutch assembly.

[0075] In order to drive the traction wheel to rotate using the main drive wheel 2-12-3, there are two traction wheels, each connected to a driven pulley. The driven pulleys are connected to the main drive wheel 2-12-3 for transmission.

[0076] In this embodiment, the traction wheel includes a first traction wheel 2-12-11 and a second traction wheel 2-12-12, wherein the first traction wheel 2-12-11 is provided with multiple traction grooves, which can prevent interference from multiple loops of yarn during the traction process.

[0077] The driven pulley coaxially arranged on the first traction wheel 2-12-11 is a single-groove pulley 2-12-13, and the driven pulley coaxially arranged on the second traction wheel 2-12-12 is a double-groove pulley 2-12-14. The main drive wheel 2-12-3 is connected to the double-groove pulley 2-12-14 via a drive belt 2-12-15, while the double-groove pulley 2-12-14 is connected to the single-groove pulley 2-12-13 via another drive belt 2-12-15. Thus, the main drive wheel 2-12-3 drives the two traction wheels to rotate synchronously.

[0078] In order to adjust the tension of the transmission belt 2-12-15 and ensure the normal operation of the roller unit 2-12, adjustable tension pulleys 2-12-16 are respectively installed on the transmission belt 2-12-15.

[0079] Specifically, the tensioner 2-12-16 is mounted on a strip plate with a slotted hole. The strip plate is fixed to a tensioning seat by adjusting bolts fitted into the slotted hole. By adjusting the position of the adjusting bolts in the slotted hole, the degree of fit between the tensioner 2-12-16 and the corresponding transmission belt 2-12-15 can be adjusted.

[0080] In this embodiment, each of the two transmission belts 2-12-15 is provided with a corresponding tensioning pulley 2-12-16.

[0081] To protect components such as the clutch assembly, tensioner 2-12-16, and driven pulley, the main drive wheel 2-12-3 and the clutch assembly are housed inside a roller housing 2-12-17, while the traction wheel is located on one side of the roller housing 2-12-17.

[0082] In this embodiment, the clutch assembly, tensioner 2-12-16, main drive wheel 2-12-3, driven pulley, etc. are all located inside the roller housing 2-12-17, while the two traction wheels are located on the same side of the outside of the roller housing 2-12-17.

[0083] To guide the yarn, a yarn guide wheel 2-12-18 and a yarn clamp 2-12-19 are provided on the outer side of the roller housing 2-12-17 on the side where the traction wheel is located, which cooperate with the traction wheel.

[0084] Specifically, a mounting plate 1-14-2 is provided on the outside of the roller housing 2-12-17 on the side where the traction wheel is located. The yarn guide wheel 2-12-18 is mounted on the mounting plate 1-14-2, and a U-shaped plate is provided at the end of the mounting plate 1-14-2. The yarn clamp 2-12-19 is mounted on the U-shaped plate.

[0085] In this embodiment, the retwisting mechanism 2-1 includes a retwisting frame 2-13, two retwisting units 2-11 arranged side by side on the retwisting frame 2-13, and a roller unit 2-12 located above the corresponding retwisting unit 2-11. All retwisting frames 2-13 of the retwisting mechanisms 2-1 and the control box 2-3 of the retwisting equipment 2 are mounted on the same retwisting base 2-4.

[0086] In order to provide power to each roller unit 2-12 through the main drive shaft 2-2, the main drive shaft 2-2 is arranged laterally above the re-twisting device 2 and cooperates with the clutch assembly of each roller unit 2-12. The main drive shaft 2-2 is connected to the drive motor 2-5.

[0087] The main drive shaft 2-2 can be a one-piece or multi-section structure. In this embodiment, the main drive shaft 2-2 is a multi-section structure, with adjacent sections connected by connectors. The drive motor 2-5 is located behind the control box 2-3 of the retwisting equipment 2 and is connected to the main drive shaft 2-2.

[0088] In order to place the take-up yarn bobbin and realize the retwisting operation, the retwisting unit 2-11 includes a retwisting spindle 2-11-1, a retwisting motor 2-11-2 for driving the retwisting spindle 2-11-1 to rotate, and a steel collar 2-11-3 that is arranged around the retwisting spindle 2-11-1 and can be raised and lowered.

[0089] The take-up yarn bobbin is placed on the retwisting spindle 2-11-1, and the retwisting motor 2-11-2 drives the retwisting spindle 2-11-1 to rotate. After the single strand of yarn is output from the primary twisting device 1, it is pulled by the roller unit 2-12 and then wound onto the take-up yarn bobbin. Specifically, the three strands of yarn that have undergone primary twisting in the same primary twisting unit 1-11 column are retwisted into one strand and wound onto the take-up yarn bobbin.

[0090] In this embodiment, the retwisting spindle 2-11-1 is located on the front side of the corresponding retwisting frame 2-13, and the retwisting motor 2-11-2 is located on the rear side of the retwisting frame 2-13 and is arranged in a front-to-back correspondence with the corresponding retwisting spindle 2-11-1. The output shaft of the retwisting motor 2-11-2 is arranged downwards, and it is connected to the retwisting rod 2-11-4 at the bottom of the corresponding retwisting spindle 2-11-1 through a transmission component (such as a transmission pulley assembly) to drive the corresponding retwisting spindle 2-11-1 to rotate.

[0091] In this invention, the initial twisting equipment 1 is configured with a horizontal layout for the initial twisting unit 1-11. The unwinding bobbin 3 (especially the double-conical bobbin) can be arranged horizontally, eliminating the tendency of the yarn to slip along the conical surface under gravity in a vertical structure. This effectively avoids yarn slippage, unwinding, and yarn tangling, reducing yarn breakage. Furthermore, during the initial twisting process, the turntable 1-11-2 constrains the yarn path, balances the yarn tension, reduces the probability of friction between the yarn and components, reduces yarn fuzzing damage, and ensures yarn processing quality. At the same time, the horizontal layout of the initial twisting unit 1-11 facilitates the arraying of multiple processing units on the initial twisting frame 1-12, making the equipment space layout flexible and improving the production efficiency of the twisting machine.

[0092] For part 2 of the retwisting equipment, by setting a clutch component in the roller unit 2-12, the transmission connection or separation between any roller unit 2-12 and the main drive shaft 2-2 can be realized. That is, when any roller unit 2-12 or its corresponding twisting equipment malfunctions, the roller unit 2-12 can be stopped and repaired separately through the clutch component without affecting the normal operation of other roller units 2-12, thus further ensuring the processing efficiency of the twisting equipment.

[0093] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
