Description

TECHNICAL FIELD

[0001] The application relates to the technical field of a yarn breakage device for a Lycra walking frame machine. BACKGROUND

[0002] Lycra blended yarn is yarn blended from Lycra fiber and other fibers, which has high elasticity and recovery, can quickly recover to the original state after stretching, makes the fabric fit and not easy to deform, has comfortable wearing feeling, can maintain good softness and comfort, fits the human body curve, has no restraint feeling, has high durability, the blending can combine the advantages of different fibers, enhance the strength and wear resistance of the yarn, improve the service life of the fabric, and has good adaptability: can be blended with various natural or chemical fibers, the blending ratio can be adjusted according to different requirements to obtain different performance characteristics, and therefore the Lycra blended yarn is often used in the fields of clothing and home textiles.

[0003] The walking frame machine refers to a type of circular knitting machine, which knits yarn into fabric through the coordinated movement of knitting needles, sinkers and other loop-forming components. The knitting needle hooks the yarn during the movement process, forms loops through actions such as loop forming and loop dropping, and a large number of loops are interlocked to form the knitted fabric. During the knitting process of the Lycra walking frame machine, the tension sensor monitors the tension change of the Lycra yarn in real time, and feeds back the signal to the control system. The control system automatically adjusts the yarn feeding speed, the force of the pulling device and the like according to the preset tension value, so that the Lycra yarn always maintains appropriate tension.

[0004] In the blending process of Lycra yarn, due to the drafting and twisting of the Lycra yarn, the yarn breakage phenomenon easily occurs, and the breakage device needs to be used to timely splice. For example, the broken yarn splicing device for blended yarn disclosed in Chinese Patent No. CN116081399B relates to the field of blended yarns, and comprises a blended yarn fixing assembly, a driving assembly and a limiting assembly. The blended yarn fixing assembly is installed on the top of the mounting plate. The blended yarn main body is provided with two roots, and the two blended yarn main bodies are arranged in the interior of the blended yarn fixing assembly. The driving assembly is installed on the rear side of the mounting plate. The limiting assembly is installed on the mounting plate and the blended yarn fixing assembly. The broken yarn splicing seat is fixedly installed on the top of the mounting plate.

[0005] Although the scheme improves the splicing precision and solves the problem of unattractive blended yarn caused by knot splicing, it is inconvenient to control the thread end in time, which easily causes waste of part of the raw material, and the contact area of the spliced thread end is small, which leads to low splicing strength and easily affects the quality of the blended yarn. SUMMARY

[0006] The application aims to provide a device for continuing the thread of a Lycra loom, which can fix the thread end immediately when the thread is broken to prevent the waste of raw materials and continue the thread, and the thread end of the continued part is automatically overlapped to improve the effect of thread continuation.

[0018] The beneficial effects of this invention are:

[0019] 1. When a break occurs, the tension on the surface of the Lycra yarn disappears instantly, and the two rotating seats move away from each other, causing the excitation device to work and drive the clamp to close, clamping the two ends of the Lycra yarn. This prevents the yarn ends from being excessively displaced and caught in the take-up roller, thus avoiding the difficulty of reconnecting the broken yarn and the waste of raw materials.

[0020] 2. In the process of reconnecting broken yarn, the present invention separates the two semicircular rings. One of the semicircular rings moves to flatten the broken Lycra yarn end on the top of the operating table, which has the effect of straightening the yarn. When the two operating tables are in contact with each other, the other semicircular ring moves to push the broken Lycra yarn end into the lower mold, so that the broken ends of the two Lycra yarns overlap each other in the lower mold, thereby increasing the contact area of ​​the broken ends and the strength of the Lycra yarn after reconnection.

[0044] like Figures 1 to 11 As shown:

[0045] A discontinuation device for a Lycra spinning machine includes a base 1. One bottom end of the base 1 is fixedly connected to the top of the spinning machine body 10. The base 1 is located between the Lycra yarn spool 11 and the yarn roller 12. The Lycra yarn 24 on the Lycra yarn spool 11 is pulled out and passes through the discontinuation device at the top of the base 1 to the top of the yarn roller 12. After blending, it is wound around the outside of the take-up roller to complete the blending process. It also includes a pair of rotating seats 2, a pair of winding rollers 20, a pair of operating tables 21, a pair of clamps 22, a pair of limiting rings 23, an excitation assembly 3, a pair of yarn handling assemblies 4, a pressing assembly 5, and a drive assembly 6. The bottom of the rotating seat 2 near the Lycra yarn spool 11 is fixedly connected to the top of the base 1, and the bottom of the rotating seat 2 near the yarn shaft roller 12 is slidably connected to the top wall of the base 1. The winding rollers 20 are rotatably connected to the inner wall of the rotating seat 2. The two ends of the Lycra yarn 24 are respectively wound around the periphery of the two winding rollers 20. The bottom of one operating table 21 is fixedly connected to the top of the base 1, and the other operating table 21 is fixedly connected to one end of the rotating seat 2 near the yarn shaft roller 12. The two winding rollers 20 are used to fix the two ends of the Lycra yarn 24, so that the surface of the Lycra yarn 24 maintains tension. During the blending process, the winding rollers 20 rotate around the rotating seat 2 to transport the Lycra yarn 24. The clamp 22 and the yarn guiding assembly 4 are both installed on the operating table 21. The clamp 22 is used to fix the Lycra yarn 24, and the yarn guiding assembly 4 is used to adjust the position of the yarn end of the Lycra yarn 24. The excitation assembly 3 is installed at the bottom of the operating table 21. The excitation assembly 3 is used to control the opening and closing of the clamp 22. When a yarn breakage occurs, the tension on the surface of the Lycra yarn 24 disappears instantly, and the two rotating seats 2 move away from each other, causing the excitation device to work and drive the clamp 22 to close, clamping the two yarn ends of the Lycra yarn 24, thereby preventing the yarn ends from being excessively displaced and caught in the take-up roller, increasing the difficulty of reconnecting the broken yarn, and causing material waste. The limiting ring 23 consists of two semicircular rings 25, which are horizontally movable and mounted on the operating table 21. The limiting ring 23 is inclined to the Lycra yarn 24, and the tops of the two semicircular rings 25 are conical to avoid mutual contact. During blending, the Lycra yarn 24 is passed through the limiting ring 23 to limit it and prevent it from shifting. After the yarn breaks, the two semicircular rings 25 separate. One of the semicircular rings 25 moves to flatten the broken end of the Lycra yarn 24 on the top of the operating table 21, which has a yarn straightening effect. When the two operating tables 21 are close together, the other semicircular ring 25 moves to push the broken end of the Lycra yarn 24 into the lower mold 50, so that the broken ends of the two Lycra yarns 24 overlap in the lower mold 50, thereby increasing the contact area of ​​the broken ends and the strength of the Lycra yarn 24 after reconnection.Both the adhesive pressing assembly 5 and the drive assembly 6 are mounted on the base 1. The adhesive pressing assembly 5 is used to squeeze the ends of the Lycra yarn 24 and apply adhesive. The drive assembly 6 is used to drive the yarn management assembly 4 and the adhesive pressing assembly 5 to work. When the two semicircular rings 25 are attached to each other to form a limiting ring 23, the Lycra yarn 24 can be limited. When one of the semicircular rings 25 moves horizontally, the position of the ends of the Lycra yarn 24 can be adjusted.

[0046] like Figures 1 to 8 As shown:

[0047] The clamp 22 includes a lower clamping plate 220, an upper clamping plate 221, a round rod 222, an insert rod 223, and a first tension spring 224. The bottom of the lower clamping plate 220 is fixedly connected to the top of the operating table 21. The bottom of the upper clamping plate 221 is in contact with the top of the lower clamping plate 220. The bottom of the round rod 222 is fixedly connected to the top of the operating table 21. One side of the upper clamping plate 221 is slidably connected to the outer periphery of the round rod 222. The top of the insert rod 223 is fixedly connected to the bottom of the other side of the upper clamping plate 221. The bottom of the insert rod 223 passes through the top wall of the operating table 21 and is slidably connected to it. The first tension spring 224 is sleeved on the outer periphery of the round rod 222. One end of the first tension spring 224 is fixedly connected to the upper clamping plate 221, and the other end of the first tension spring 224 is fixedly connected to the top of the operating table 21.

[0048] The actuation assembly 3 includes a long rod 30, a pair of push blocks 31, a pair of limiting plates 32, and a first spring 33. The two ends of the long rod 30 pass through the side walls of the two operating tables 21 and are slidably connected to them. The two ends of the long rod 30 are fixedly connected to the two push blocks 31. The limiting plates 32 are fixedly connected to the periphery of the long rod 30. The first spring 33 is sleeved on the periphery of the long rod 30. One end of the first spring 33 is fixedly connected to the push block 31, and the other end of the first spring 33 is fixedly connected to the inner wall of the operating table 21. When the two operating tables 21 move away from each other, one of the limiting plates 32 abuts against the inner wall of the operating table 21, the first spring 33 is compressed, the push block 31 separates from the insertion rod 223, and the clamp 22 can be closed. When the two operating tables 21 move closer to each other, the first spring 33 rebounds, the other limiting plate 32 abuts against one end of the operating table 21, the push block 31 pushes up the insertion rod 223, and the clamp 22 can be opened.

[0049] The excitation assembly 3 also includes a first hydraulic rod 34 and a pair of second tension springs 35. One end of the first hydraulic rod 34 is fixedly connected to the base 1, and the telescopic end of the first hydraulic rod 34 abuts against the bottom of one end of the rotating seat 2. One end of the second tension spring 35 is fixedly connected to the base 1, and the other end of the second tension spring 35 is fixedly connected to the bottom of one end of the rotating seat 2.

[0050] During the blending process, the Lycra yarn 24 is passed through the top of the lower clamping plate 220. Due to the tension of the Lycra yarn 24, the two operating tables 21 are pressed together, the second tension spring 35 is in a stretched state, and the long rod 30 is positioned exactly in the middle of the bottom of the two operating tables 21 under the action of the rebound force of the first spring 33 and the pushing force of the inner wall of the operating table 21. The two insert rods 223 are respectively lifted by the two push blocks 31, the upper clamping plate 221 is separated from the lower clamping plate 220, the first tension spring 224 is stretched, the clamp 22 is in an open state, and the Lycra yarn 24 can move normally. When a breakage occurs, the tension of the Lycra yarn 24 on the winding roller 20 disappears, the second tension spring 35 rebounds, causing one of the rotating seats 2 to slide on top of the base 1 and quickly move away from the other rotating seat 2, causing the two operating tables 21 to move away from each other. At the same time, the inner wall of one of the operating tables 21 abuts against the limiting piece 32 on the long rod 30, causing the long rod 30 to continue moving, compressing the first spring 33, separating the insertion rod 223 from the push block 31. Subsequently, the first tension spring 224 rebounds, causing the upper clamping plate 221 to slide down along the round rod 222 and cooperate with the lower clamping plate 220 to hold the broken end of the Lycra yarn 24, thereby preventing displacement of the broken end. Then the first hydraulic rod 34 works, pushing the rotating seat 2 and the operating table 21 to reset, performing the breakage re-operation. At the same time, the long rod 30 resets and pushes the insertion plate through the push block 31, causing the clamp 22 to open.

[0051] like Figures 1 to 9 As shown:

[0052] The cable management assembly 4 includes a second hydraulic rod 40. One end of the second hydraulic rod 40 is fixedly connected to the top of the operating table 21, and the other end of the second hydraulic rod 40 is fixedly connected to one of the semicircular rings 25. The two second hydraulic rods 40 are arranged in a centrally symmetrical manner and in opposite directions.

[0053] The cable management assembly 4 also includes an L-shaped slide bar 41 and a third tension spring 42. One side of the L-shaped slide bar 41 is fixedly connected to another semi-circular ring 25. The bottom of the L-shaped slide bar 41 passes through the top wall of the operating table 21 and is slidably connected to it. One end of the third tension spring 42 is slidably connected to the L-shaped slide bar 41, and the other end of the third tension spring 42 is fixedly connected to the top of the operating table 21.

[0054] When the two operating tables 21 separate due to a yarn breakage, the second hydraulic rod 40 is activated first, pushing one of the semicircular rings 25 to move horizontally. The broken end of the Lycra yarn 24 is moved to the top of the operating table 21 through the semicircular ring 25. The two semicircular rings 25 are symmetrical, so that the broken ends of the two Lycra yarns 24 are in opposite directions, which facilitates subsequent straightening. After the operating table 21 is reset, the L-shaped slide bar 41 is pushed, causing it to move another semicircular ring 25 horizontally. The third tension spring 42 is stretched, and the two semicircular rings 25 forming a limiting ring 23 move in perpendicular directions to each other. This allows the broken ends of the Lycra yarn 24 to be turned back to the correct direction. By using the semicircular rings 25 to move the broken ends of the Lycra yarn 24, the two broken ends are made to fit tightly together and enter the lower mold 50 to wait for adhesive bonding. Then, the third tension spring 42 rebounds, causing the semicircular ring 25 to reset. Since the Lycra yarn 24 is stretched during the breaking process, when the operating table 21 is reset, the two broken ends of the Lycra yarn 24 overlap each other in the lower mold 50, which improves the strength of the Lycra yarn 24 after the breakage.

[0055] like Figures 1 to 8 As shown:

[0056] The pressure bonding assembly 5 includes a lower mold 50, an upper mold 51, a guide rod 52, a screw 53, and a micro pump 54.

The bottoms of the guide rod 52 and the screw 53 are fixedly connected to the top of the base 1. The bottom of the upper mold 51 is in contact with the top of the lower mold 50. One side of the upper mold 51 is slidably connected to the outer periphery of the guide rod 52, and the other side of the upper mold 51 is threadedly connected to the outer periphery of the screw 53. The bottom of the micro pump 54 is fixedly connected to the top of the upper mold 51, and the outlet of the micro pump 54 is connected to the inside of the upper mold 51 through a hose. After the broken ends of Lycra yarn 24 are pushed into the lower mold 50, the screw 53 is rotated. Through the threaded transmission between the screw and the upper mold 51, the upper mold 51 is moved down and comes into contact with the lower mold 50, pressing the broken ends of Lycra yarn 24 between the two molds. Then, the micro pump 54 is activated, and fine glue is injected into the upper mold 51 through the hose to bond the two broken ends of Lycra yarn 24 together, thus completing the breakage repair.

Multiple grooves 651 are formed on the outer periphery of the wheel body 650. One end of the pawl 652 is rotatably connected to the inner wall of the groove 651. The multiple pawls 652 are arranged in a circle around the outer periphery of the wheel body 650. One end of the second spring 653 is fixedly connected to the inner wall of the groove 651, and the other end of the second spring 653 is fixedly connected to the pawl 652.

[0061] The third hydraulic rod 63 is activated, pushing the rack 64 to move horizontally. The rack 64 first contacts the ratchet 65, at which point the pawl 652 abuts against the inner wall of the groove 651, causing the ratchet 65 and the rack 64 to mesh with each other, thereby driving the rotating shaft 60 and the push plate 61 to rotate. During the rotation of the push plate 61, the bottoms of the two L-shaped slide bars 41 are simultaneously squeezed, causing them to drive the semi-circular ring 25 to move horizontally at the top of the operating table 21, straightening the broken end of the Lycra yarn 24. Then the rack 64 separates from the ratchet 65, the semi-circular ring 25 resets and pushes the push plate 61 to rotate. As the rack 64 continues to move and contacts the gear 66, the two mesh with each other, thereby driving the screw 53 to rotate, causing the upper mold 51 to move down for pressing. After the interruption is completed, the third hydraulic rod 63 drives the rack 64 to reset, and the upper mold 51 rises to its original position. When the gear 66 contacts the pawl 652 on the ratchet 65, it pushes the ratchet 65 and the rotating shaft 60 to rotate until the protrusion 62 at the bottom of the rotating shaft 60 abuts against the protrusion 13 on the top wall of the base 1, preventing the push plate 61 from rotating too much and hindering the movement of the L-shaped slide bar 41. At this time, the rack 64 continues to move and squeezes the pawl 652, causing it to rotate around one end. The second spring 653 is compressed, thereby avoiding jamming and allowing the rack 64 to pass smoothly and reset.
