AI Technical Summary
In existing twisting devices, after the cashmere yarn breaks in the clamping component, the yarn end cannot be immediately retained in its original position, resulting in an unsightly splice, affecting the texture and strength of the yarn. Furthermore, the failure to stop the equipment in time when multiple strands break results in insufficient strength of the produced yarn.
An adjustable twisting mechanism for cashmere yarn was designed. The mechanism uses an electromagnet to control the disengagement of the hammer and the limiting teeth, automatically stopping the rotation of the spindle corresponding to the broken yarn bundle. The twist is adjusted by a gravity sensor plate to prevent manual knotting and ensure that other yarn bundles are twisted normally.
It enables automatic shutdown of the equipment after a thread breakage, preventing the yarn bundle from rubbing and knotting, improving the strength and appearance of the yarn, and ensuring the continuity and efficiency of the twisting process.

Technical Field
[0001] This invention relates to the field of cashmere yarn twisting technology, specifically to a cashmere yarn twisting mechanism with adjustable twist and its twisting process. Background Technology
[0002] Cashmere blended yarn refers to yarn spun from multiple strands of yarn mixed in a certain proportion. When a yarn breaks during the processing of blended yarn, it needs to be reconnected using a splicing device. In existing twisting devices, each yarn experiences different tension. Currently, most yarn breaks occur in the clamping components during blended yarn processing, and the broken yarn ends fall directly to the ground, making it impossible to immediately retain the yarn ends in their original positions. Therefore, manual knotting is often required for splicing, resulting in an unsightly spliced blended yarn. Furthermore, the spliced yarn rubs against the already twisted yarn on the blending bobbin, easily causing knots and pushing the fibers back up, affecting the yarn's texture, significantly reducing its strength, and resulting in a less dense and rougher yarn surface. If one strand breaks during twisting and the equipment is not stopped in time, the produced yarn will also lack strength. Therefore, we propose a cashmere yarn twisting mechanism and its twisting process with adjustable twist. Summary of the Invention

[0007] Preferably, one end of the balance bar is fixedly connected to multiple connecting rods, one end of each connecting rod is fixedly connected to a groove, and partitions are fixedly installed around the bottom of the groove. A spring is fixedly connected to one side of the partition, and a fixing plate is fixedly connected to one end of the spring.

[0008] Preferably, the shaft end of the irreversible roller passes through the baffle and extends to its outer side. Each irreversible roller shaft is fixedly connected to a ratchet. A positioning plate is fixedly installed on one side of the baffle. A return spring is fixedly connected to one side of the positioning plate. A pawl is rotatably connected to the baffle near the ratchet. The pawl and the ratchet engage.
[0009] Preferably, the puller includes a positioning buckle slidably connected to the slide groove, a semi-circular retaining plate fixedly installed on one side of the positioning buckle, a mating retaining plate detachably connected to the top of the semi-circular retaining plate, and the semi-circular retaining plate and the mating retaining plate are fixed together by bolts.
[0010] Preferably, a gravity sensing plate is fixedly installed on the top of the transmission box, and multiple connecting columns are fixedly connected to the top of the gravity sensing plate. A spindle is sleeved on the connecting column, and a mounting rod is detachably connected to the top of the connecting column. A shim plate is fixedly installed on the transmission box near the gravity sensing plate, and multiple columns are detachably connected to the shim plate. A first electromagnet is suspended from the top of the columns. A connecting plate is fixedly connected to the top of the mounting rod, and multiple expansion rods are rotatably connected to the outer edge of the connecting plate. A top plate is hinged between the multiple expansion rods, and a rocker arm is hinged to the middle of each expansion rod. A lifting cylinder is movably connected to the common end of the multiple rocker arms. The first electromagnet and the lifting cylinder are connected together by magnetic attraction.
[0011] Preferably, the center of the groove is recessed downward to form a hollow hole through which the cashmere yarn passes, and the irreversible roller is made of a non-slip material.
[0012] Preferably, the twisting process required for the twisting mechanism of the adjustable twist cashmere yarn during operation includes step A: yarn loosening process: the cashmere raw material is manually fed into the impurity removal device for pretreatment, and then the impurity-removed cashmere is manually taken out and sent to the dyeing machine for dyeing. Then the dyed cashmere enters the carding machine, and through multiple carding, the disordered cashmere clumps are turned into thin layers similar to "cotton candy", and the fibers are gradually evenly distributed; this process is repeated until a preliminary yarn structure is formed. Step B: Twisting pretreatment: The impurity removal device in Step A is executed again, and a laser colorimeter is used to identify and screen the color depth of the cashmere yarn. The laser colorimeter is set with a certain threshold. When the tested color is lower than the threshold, the cashmere yarn cannot pass through the carding machine. Instead, the cashmere yarn that passes through the carding machine is collected by the winding roller structure. Step C: Twisting Process: After the winding roller structure has collected a certain amount of cashmere, it is manually transferred to the spindle for fixation. Then, the cashmere yarn end is manually pulled out and wound around the outer ring of one of the expansion rods. Next, one end of the cashmere yarn is passed through the puller. The puller is pulled and slides along the groove, allowing it to pass over the moving rod first, causing the telescopic rod above the top rod to extend. The adjusting rod is then manually pulled out, causing the top of the positioning tooth to lock into the limit position. On the teeth, the adjusting rod is temporarily prevented from resetting, and then the end of the cashmere yarn is passed through the pocket. When the cashmere yarn passes through the pocket, the outer circle of the cashmere yarn contacts the unidirectional rotating irreversible roller. Multiple irreversible rollers clamp the cashmere yarn, thus limiting one end of the cashmere yarn. Finally, the end of the cashmere yarn is drawn into the roller. The cashmere yarn is then collected by winding through the coil. Then, the existing device of the control unit inside the gravity sensor plate is activated. The drive rotation of each connecting column is not shown, and the twisting of the cashmere yarn begins. Step D: Adaptive Twisting Function: The current allocated to the first electromagnet is determined by the weight of the spindle itself. When the weight of the spindle is too great, the current through the first electromagnet is greater, which in turn attracts a greater magnetic force to the lifting cylinder. This causes the lifting cylinder to lower the rocker arm, which in turn lowers the expansion rod, reducing the area where the cashmere yarn is thrown radially outward from the spindle. This indirectly increases the spindle's rotation speed, thereby increasing the twist of the cashmere yarn and improving the processing speed. Conversely, it reduces the twist. Step E: Emergency Twisting Function: When the cashmere yarn breaks during clamping, the yarn puller immediately descends without force. The wedge touches the switch, triggering an electrical signal to the second electromagnet, causing the spindle to stop abruptly. The second electromagnet becomes magnetic, driving the hammer head downwards, disengaging the positioning and limiting teeth, and resetting the telescopic rod. During the descent of the yarn puller, its own gravity causes the adjusting rod to move forward, facilitating the disengagement of the positioning and limiting teeth. As the telescopic rod resets, the moving rod brings the broken end of the cashmere yarn into contact with the side of the chute, simultaneously triggering the swing rod to fold on the top rod. The top of the swing rod moves towards the bending part of the bending rod until the moving rod brings the end of the cashmere yarn to the end of the chute and stops. The spindle corresponding to the cashmere yarn stops working, and finally, the broken cashmere yarn is manually pulled back.
[0013] Compared with the prior art, the beneficial effects of the present invention are: When the cashmere yarn breaks during clamping, this invention allows the positioning teeth and limiting teeth to disengage, and the telescopic rod to reset. During the descent of the puller, its own gravity causes the adjusting rod to move forward, facilitating the disengagement of the positioning teeth and limiting teeth. As the telescopic rod resets, the moving rod brings the broken end of the cashmere yarn into contact with the side of the chute, simultaneously triggering the swing rod to fold on the top rod. The top of the swing rod moves towards the bending part of the bending rod until the moving rod stops, bringing the end of the cashmere yarn to the end of the chute. This prevents manual knotting of the cashmere yarn bundle. Finally, after the spindle corresponding to the broken yarn bundle stops rotating, it does not affect the twisting of other yarn bundles. After the twisting of other yarn bundles is completed, the broken yarn bundle is re-twisted, preventing multiple yarn bundles from running side-by-side, which could cause friction between the twisted yarns, leading to knotting and the fibers being pushed up again.

[0016] 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, and 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.
[0017] Please see Figure 1-8This invention provides a technical solution: a twisting mechanism for cashmere yarn with adjustable twist, comprising a pair of parallel base columns 1 placed on the ground, a balance bar 2 fixedly connected between the middle of the two base columns 1, a plurality of bending rods 11 fixedly connected to the bottom of one end of the balance bar 2, a top rod 1101 fixedly connected to one end of each bending rod 11, a swing rod 13 hinged to the end of the top rod 1101, a sliding groove 19 fixedly installed on the swing rod 13, a puller 21 slidably connected to the sliding groove 19, a wedge 20 fixedly installed on one side of the bottom of the puller 21, and an extension rod 12 fixedly connected to one side of the other end of the bending rod 11, the top of the extension rod 12 being slidably mounted on... The device is equipped with a hammer head 1201. A second electromagnet 41 is fixedly installed on the top of the extension rod 12. A positioning tooth 40 is fixedly installed on the side of the hammer head 1201. A telescopic rod is fixedly installed near the bending rod 11 next to 1202. A control head 16 is fixedly connected to one end of the telescopic rod. An adjusting rod 17 is rotatably connected to the control head 16. Multiple limiting teeth 1701 are provided at the bottom of the adjusting rod 17. The control head 16 and the limiting teeth 1701 mesh together. A limiting block 18 is fixedly connected to the end of the adjusting rod 17 near the control head 16. A moving rod 14 is fixedly connected to one end of the adjusting rod 17. A switch 15 is fixedly connected to the moving rod 14. The switch 15 is located below the moving trajectory of the wedge block 20. When the cashmere yarn breaks during clamping, the puller 21, unaffected by force, immediately descends. The wedge 20 contacts the switch 15, which triggers an electrical signal to the second electromagnet 41, causing the spindle 10 to stop abruptly. The second electromagnet 41 becomes magnetic, driving the hammer 1201 downwards, disengaging the positioning tooth 40 and the limiting tooth 1701, and resetting the telescopic rod. During the descent of the puller 21, its own weight causes the adjusting rod 17 to move forward, facilitating the disengagement of the positioning tooth 40 and the limiting tooth 1701. As the telescopic rod resets, the moving rod 14 causes the broken end of the cashmere yarn to contact the side of the slide groove 19. When the contact is made, the swing rod 13 is folded on the top rod 1101. The top of the swing rod 13 moves toward the bending part of the bending rod 11 until the moving rod 14 drives the end of the cashmere yarn to the end of the slide groove 19 and stops. This prevents manual knotting of the cashmere yarn bundle. After the spindle 10 corresponding to the broken yarn bundle stops rotating, it does not affect the twisting work of other yarn bundles. After the twisting work of other yarn bundles is completed, the yarn bundle can be manually pulled into the coil 7 for use, so as to re-twist the broken yarn bundle. This prevents multiple yarn bundles from being arranged side by side, which would cause the yarn to rub together, making it easy to knot and push the fiber yarn up again.
[0018] Furthermore, a transmission box 4 is fixedly installed at the bottom between the two base columns 1, a central rod 3 is fixedly connected to one side of the top of each base column 1, a coiled wire 7 is fixedly connected between the two central rods 3, and a hanging rod 8 is fixedly connected to the end between the two central rods 3. Multiple rollers 9 are suspended on the hanging rod 8.
[0019] Furthermore, a plurality of connecting rods 5 are fixedly connected to one end of the balance bar 2, and a groove 6 is fixedly connected to one end of each connecting rod 5. A partition 35 is fixedly installed around the bottom of the groove 6. A spring 33 is fixedly connected to one side of the partition 35, and a fixing plate 32 is fixedly connected to one end of the spring 33. A stopper rod is movably connected to the partition 35, and a baffle 36 is fixed to one end of the stopper rod. An irreversible roller 34 is rotatably connected to the baffle 36. The groove 6 is recessed downwards to form a hollow hole through which cashmere yarn passes. The irreversible roller 34 is made of a non-slip material. The shaft end of the irreversible roller 34 passes through the baffle 36 and extends outwards. Each irreversible roller 34 has a ratchet 37 fixedly connected to its shaft. A positioning plate 39 is fixedly installed on one side of the baffle 36, and a recoil spring 38 is fixedly connected to one side of the positioning plate 39. A pawl is rotatably connected to the baffle 36 near the ratchet 37. The pawl and the ratchet 37 mesh. Multiple irreversible rollers 34 prevent the yarn from rotating axially. The yarn is twisted between the multiple irreversible rollers 34 and the spindle 10. When the yarn moves upward, the yarn can be stretched evenly by the yarn pulling speed of the roller 9, so that the yarn on the coil 7 can be coiled more evenly, and at the same time, it prevents the yarn from falling to the ground after breaking.
[0020] Furthermore, the cable puller 21 includes a positioning buckle that is slidably connected to the slide groove 19. A semi-circular retaining plate is fixedly installed on one side of the positioning buckle. A mating retaining plate is detachably connected to the top of the semi-circular retaining plate. The semi-circular retaining plate and the mating retaining plate are fixed together by bolts.
[0021] Furthermore, a gravity sensing plate 22 is fixedly installed on the top of the transmission box 4. Multiple connecting columns 31 are fixedly connected to the top of the gravity sensing plate 22. A spindle 10 is sleeved on each connecting column 31. A mounting rod 30 is detachably connected to the top of each connecting column 31. A raised plate 23 is fixedly installed near the gravity sensing plate 22 in the transmission box 4. Multiple columns 24 are detachably connected to the raised plate 23. A first electromagnet 25 is suspended from the top of each column 24. A connecting plate is fixedly connected to the top of the mounting rod 30. Multiple expansion rods 28 are rotatably connected to the outer edge of the connecting plate. A top plate 29 is hinged between the expansion rods 28. A rocker arm 27 is hinged to the middle of each expansion rod 28. A lifting cylinder 26 is movably connected to the common end of multiple rocker arms 27. During equipment installation, a return spring (not shown) is placed between the top plate 29 and the lifting cylinder 26 to prevent the lifting cylinder 26 from constantly contacting the first electromagnet 25. The first electromagnet 25 and the lifting cylinder 26 are magnetically connected. The transmission box 4 has an independent transmission structure (not shown) that controls the rotation of each spindle 10. When adjustment is needed... When adjusting the twist of the equipment, the weight of the yarn on spindle 10 can be adaptively adjusted. When the weight on spindle 10 is relatively large, the yarn layer is too thick and needs to be processed quickly. Furthermore, based on the weight of the yarn, the sensing module of gravity sensing plate 22 receives the gravity and sends a report to the backend. The backend executes a command to push a larger current, which strengthens the magnetism of the first electromagnet 25, increasing the descent amplitude of the lifting cylinder 26. This causes the multiple rocker arms 27 to retract, reducing the rotation radius of the expansion rod 28. Simply place the cashmere yarn at the spherical structure at the end of one of the expansion rods 28. When the expansion rod 28 rotates, the yarn on the spindle 10 can be quickly separated. When the expansion rod 28 rotates in conjunction with the spindle 10, the radius of rotation of the expansion rod 28 becomes smaller, resulting in a smaller radius of rotation of the yarn along the axis of the spindle 10. The yarn itself rotates faster, so the twist is improved compared to before. However, the spindle 10 rotates at a relatively low speed, so the twist is smaller, and the yarn needs to be separated to prevent the yarn from tangling together.
[0022] The twisting process required for the cashmere yarn twisting mechanism during operation includes step A: yarn loosening process: The cashmere raw material is manually fed into the impurity removal device for pretreatment. Then, the impurity-removed cashmere is manually removed and sent to the dyeing machine for dyeing. The dyed cashmere then enters the carding machine, where it is repeatedly carded to turn the messy clumps into thin layers similar to "cotton candy," gradually distributing the fibers evenly. This process is repeated until a preliminary yarn structure is formed. Step B: Twisting pretreatment: The impurity removal device in Step A is executed again, and a laser colorimeter is used to identify and screen the color depth of the cashmere yarn. The laser colorimeter is set with a certain threshold. When the tested color is lower than the threshold, the cashmere yarn cannot pass through the carding machine. Instead, the cashmere yarn that passes through the carding machine is collected by the winding roller structure (the existing device will not be described in detail). Step C: Twisting Process: After the winding roller structure collects a certain amount of cashmere, it is manually transferred to the spindle 10 for fixation. Then, the cashmere yarn end is manually pulled out and wound around the outer ring of one of the expansion rods 28. Next, one end of the cashmere yarn is passed through the puller 21. The puller 21 is subjected to tension, causing it to slide along the slide groove 19. The puller 21 first passes over the moving rod 14, allowing the telescopic rod above the top rod 1101 to extend. The adjusting rod 17 is then manually pulled out, causing the top of the positioning tooth 40 to engage. On the limiting tooth 1701, the adjusting rod 17 is temporarily prevented from resetting. Then, the end of the cashmere yarn is passed through the pocket 6. When the cashmere yarn passes through the pocket 6, the outer ring of the cashmere yarn contacts the unidirectional rotating irreversible roller 34. Multiple irreversible rollers 34 clamp the cashmere yarn, thus limiting one end of the cashmere yarn. Finally, the end of the cashmere yarn is pulled into the roller 9. The cashmere yarn is finally coiled and collected by the winding spool 7. Then, the existing device of the control unit inside the gravity sensor plate 22 is turned on. The drive rotation of each connecting column 31 is not shown, and the twisting of the cashmere yarn begins. Step D: Adaptive Twisting Function: The weight of the spindle 10 determines the current supplied to the first electromagnet 25. When the weight of the spindle 10 is too great, the current through the first electromagnet 25 is greater, which in turn attracts a greater magnetic force to the lifting cylinder 26. The lifting cylinder 26 then drives the rocker arm 27 to descend, causing the expansion rod 28 to descend as well. This reduces the area of the cashmere yarn that is thrown radially outward toward the spindle 10, indirectly increasing the rotational speed of the spindle 10. This increases the twist of the cashmere yarn and improves the processing speed. Conversely, it reduces the twist. Step E: Emergency Twisting Function: When the cashmere yarn breaks during clamping, the puller 21 immediately descends without force. The wedge 20 touches the switch 15, which triggers an electrical signal to the second electromagnet 41, causing the spindle 10 to stop abruptly. The second electromagnet 41 becomes magnetic, driving the hammer 1201 downwards, disengaging the positioning tooth 40 from the limiting tooth 1701, and resetting the telescopic rod. During the descent of the puller 21, its own weight causes the adjusting rod 17 to... The forward movement facilitates the disengagement of the auxiliary positioning tooth 40 and the limiting tooth 1701. During the resetting process of the telescopic rod, the moving rod 14 drives the broken end of the cashmere yarn to contact the side of the slide groove 19, while triggering the swing rod 13 to fold on the top rod 1101. The top of the swing rod 13 moves towards the bending part of the bending rod 11 until the moving rod 14 drives the end of the cashmere yarn to the end of the slide groove 19 and stops. The spindle 10 corresponding to the cashmere yarn stops working, and finally the broken cashmere yarn is manually pulled again.

9. The twisting process required for the operation of the cashmere yarn twisting mechanism with adjustable twist according to any one of claims 1-8, characterized in that: Step A: Yarn preparation process: Cashmere raw materials are manually fed into a de-impurity removal device for pretreatment. Then, the de-impurity cashmere is manually removed and sent to a dyeing machine for dyeing. The dyed cashmere then enters a carding machine, where it is combed multiple times to transform the messy clumps into thin layers (similar to "cotton candy"), gradually distributing the fibers evenly. This process is repeated until a preliminary yarn structure is formed. Step B: Twisting pretreatment: The impurity removal device in Step A is executed again, and a laser colorimeter is used to identify and screen the color depth of the cashmere yarn. The laser colorimeter is set with a certain threshold. When the tested color is lower than the threshold, the cashmere yarn cannot pass through the carding machine. Instead, the cashmere yarn that passes through the carding machine is collected by the winding roller structure. Step C: Twisting treatment: After the winding roller structure collects a certain amount of cashmere, the winding roller structure is manually transferred to the spindle (10) for fixation. Then, the head end of the cashmere yarn is manually pulled out and the cashmere yarn is wound around the outer ring of one of the expansion rods (28). Then, one end of the cashmere yarn is passed through the puller (21). The puller (21) is subjected to tension, causing it to slide along the groove (19). The puller (21) first passes over the moving rod (14), allowing the telescopic rod above the top rod (1101) to extend. The adjusting rod (17) is manually pulled out, causing the top of the positioning tooth (40) to lock. On the limiting tooth (1701), the adjusting rod (17) is temporarily prevented from resetting, and then the end of the cashmere yarn is passed through the pocket (6). When the cashmere yarn passes through the pocket (6), the outer ring of the cashmere yarn contacts the unidirectional rotating irreversible roller (34). Multiple irreversible rollers (34) clamp the cashmere yarn, so that one end of the cashmere yarn is limited. Finally, the end of the cashmere yarn is pulled into the roller (9). The cashmere yarn is finally collected by winding through the coil (7). Then the internal control unit (existing device, not shown) of the gravity sensor plate (22) is turned on to drive each connecting column (31) to rotate and start twisting the cashmere yarn. Step D: Adaptive Twisting Processing: The current allocated to the first electromagnet (25) is determined by the weight of the spindle (10). When the weight of the spindle (10) is too great, the current through the first electromagnet (25) is relatively large, and the magnetic force of the first electromagnet (25) attracting the lifting cylinder (26) is relatively large. The lifting cylinder (26) drives the rocker arm (27) to descend, and the expansion rod (28) descends, reducing the area of the cashmere yarn that is thrown radially outward towards the spindle (10). This indirectly increases the rotation speed of the spindle (10), thereby increasing the twist of the cashmere yarn and improving the processing speed. Conversely, it reduces the twist. Step E: Twisting Emergency Function: When the cashmere yarn breaks during clamping, the puller (21) immediately descends without force, the wedge (20) touches the switch (15), the switch (15) triggers an electrical signal to the second electromagnet (41), and the spindle (10) stops abruptly. The second electromagnet (41) generates magnetism, and the second electromagnet (41) drives the hammer (1201) to move downward, causing the positioning tooth (40) and the limiting tooth (1701) to disengage, allowing the telescopic rod to reset. During the descent of the puller (21), due to its own gravity, the adjusting rod (1701) is adjusted. Moving forward, it is easier to disengage the auxiliary positioning tooth (40) and the limiting tooth (1701). During the resetting process of the telescopic rod, the moving rod (14) drives the broken end of the cashmere yarn to contact the side of the slide groove (19), and at the same time triggers the swing rod (13) to fold on the top rod (1101). The top of the swing rod (13) moves towards the bending part of the bending rod (11) until the moving rod (14) drives the end of the cashmere yarn to the end of the slide groove (19) and stops. The spindle (10) corresponding to the cashmere yarn stops working. Finally, the broken cashmere yarn is pulled back by hand.
