Description

Technical Field

[0001] This invention relates to the field of compact spinning yarn production technology, specifically to an automatic splicing mechanism for compact spinning yarn. Background Technology

[0002] Compact spinning, also known as compact spinning, is a ring spinning method that produces yarns with a more compact structure. The compacting device gradually reduces the width of the sliver output from the front roller to a size close to the yarn diameter. At the same time, the twisting action of the traveler reaches the output nip line of the compacting device, completely changing the situation of edge fiber loss and end fiber protrusion outside the yarn body as fuzz in ring spinning.

[0003] Spinning machines are affected by various factors during the spinning process, and yarn breakage is inevitable. Therefore, yarn breakage splicing is the most common operation in the spinning process. In the prior art, the invention with announcement number CN105568455B discloses an automatic yarn breakage splicer, which includes a guide frame, four pairs of rollers, a twisting and splicing device, a drive roller pair, and a clamping roller pair. The yarn enters the twisting and splicing device through the guide frame and four pairs of rollers, and then, after twisting, it enters the yarn winding device through the drive roller pair and the clamping roller pair. When a yarn breakage is detected, the drive roller pair and the clamping roller pair can pull the front part of the broken yarn back to facilitate the broken yarn being sucked into the twisting and splicing device and loosened. Then, the twisting and splicing device also sucks in the rear part of the broken yarn to complete the splicing process. The advantages of this invention are that it has a compact structure and excellent splicing quality.

[0004] In the above technology, the drive roller pair and the holding roller pair can pull the front section of the broken thread back to facilitate the broken thread being sucked into the twisting and splicing device and loosened. Then, the twisting and splicing device also sucks in the rear section of the broken thread to complete the splicing process. However, when the roller pair and the holding roller pull the broken thread back, they cannot control the pull-back distance, resulting in the broken thread being too long or too short, which affects the connection of broken yarns.

Then, the second automatic telescopic rod and the heating plate are started to heat the yarn and fuse the yarn end.

[0034] 2. When the yarn is being conveyed, the taut yarn will press against the elastically set shelf upwards, thus preventing the signal at the bottom of the shelf from contacting the trigger plate. When the yarn breaks, the elastically set shelf is no longer limited by the yarn, causing the signal to contact the trigger plate. At this time, the signal is triggered, and the second motor receives the signal to stop conveying the yarn. Attached Figure Description

[0051] Base 1, with a wiring chamber 3 on top of the base 1, and a traction head 22 at both ends of the wiring chamber 3;

[0052] A clamping assembly is disposed inside the traction head 22. The clamping assembly is used to clamp the broken wire inside the traction head 22, and a cutting assembly is disposed inside the traction head 22 on one side corresponding to the clamping assembly.

[0053] A wiring assembly is rotatably disposed inside the wiring chamber 3. The wiring assembly is used to connect the two ends of a broken wire. The wiring assembly includes a heating plate 36.

[0054] The broken yarn is clamped by the clamping assembly inside the traction head 22, and then the cutting assembly cuts off the front end of the broken yarn. After cutting, with the cooperation of the clamping assembly, the two ends of the yarn are pulled by the two sets of traction heads 22 into the splicing chamber 3, where they are spliced ​​by the splicing assembly inside the splicing chamber 3.

[0055] Example 2:

[0056] like Figure 2 and Figure 3 As shown, the automatic splicing mechanism for the spun yarn disclosed in Embodiment 2 of the present invention has a structure that is basically the same as that in Embodiment 1, except that:

[0060] One set of support plates 4 is equipped with a second motor 20 at the position corresponding to the drive roller pair 6, and the drive roller pair 6 rotates in opposite directions through the two sets of second motors 20.

[0061] The yarn is guided by the cooperation of the front roller pair 5, drive roller pair 6, middle roller pair 7, and rear roller pair 8. Then, the second motor 20 drives the drive roller pair 6 to rotate, thus conveying the yarn.

[0062] Example 3:

[0063] like Figure 4 As shown, the automatic splicing mechanism for the spun yarn disclosed in Embodiment 3 of the present invention has a structure that is basically the same as that in Embodiment 2, except that:

[0066] Signal device 17 is electrically connected to the second motor 20;

[0067] When the yarn is being conveyed, the taut yarn will press against the elastically set shelf 16, preventing the signal device 17 at the bottom of the shelf 16 from contacting the trigger plate 18. When the yarn breaks, the elastically set shelf 16 is no longer limited by the yarn, causing the signal device 17 to contact the trigger plate 18. At this time, the signal device 17 is triggered, and the second motor 20 receives the signal to stop conveying the yarn.

[0068] Example 4:

[0069] like Figure 2 and Figure 3 As shown, the automatic splicing mechanism for the spun yarn disclosed in Embodiment 4 of the present invention has a structure that is basically the same as that in Embodiment 3, except that:

[0070] The upper surface of the base 1 is provided with two sets of symmetrically distributed sliding grooves 11. Each sliding groove 11 is rotatably equipped with a double-headed lead screw 12. The side wall of the base 1 is provided with a first motor 13 corresponding to the end position of each double-headed lead screw 12.

The two sets of traction heads 22 are respectively connected to the upper ends of the corresponding two sets of second support frames 10.

[0072] When the yarn breaks, the first motor 13 is started. Through the cooperation of the double-headed lead screw 12 and the slider 14, the traction head 22 and the yarn inside the traction head 22 are driven to be inserted into the wiring chamber 3 in a synchronous manner.

[0073] Example 5:

[0074] like Figure 5 - Figure 7 and Figure 9 - Figure 11 As shown, the automatic splicing mechanism for the spun yarn disclosed in Embodiment 5 of the present invention has a structure that is basically the same as that in Embodiment 4, except that:

[0075] Both ends of the wiring chamber 3 are provided with top covers 21. The top covers 21 have a ring structure. The diameter of the traction head 22 is matched with the inner diameter of the top cover 21, and a wire hole 23 is opened at the center of the traction head 22.

[0076] A countersunk hole 24 is provided at the center of one end of the traction head 22 facing the wiring chamber 3. The clamping component and the cutting component are both set inside the countersunk hole 24. The cutting component is fixedly set on one side of the opening end of the countersunk hole 24, and the clamping component is slidably set inside the countersunk hole 24.

[0077] Both the clamping assembly and the cutting assembly include a first adjusting ring 25, wherein one set of first adjusting rings 25 is fixed inside the countersunk hole 24, and another set of first adjusting rings 25 is slidably disposed inside the countersunk hole 24, and multiple sets of first automatic telescopic rods 26 are installed between the two sets of first adjusting rings 25 at intervals.

[0078] Both sets of first adjusting rings 25 have cavities 38 inside, and each cavity 38 has a second adjusting ring 39 rotatably installed inside. The inner wall of the second adjusting ring 39 has multiple sets of spaced oblique grooves 42. The inner wall of the first adjusting ring 25 has a matching through groove 43 at the position of each oblique groove 42. The through groove 43 passes through the first adjusting ring 25 and communicates with the oblique groove 42.

[0079] Each through slot 43 is fitted with a clamping block 44, and each clamping block 44 is fitted with a second limiting block 47 on its side wall.

The second limiting block 47 is slidably disposed inside the second limiting groove 45, and a second return spring 46 is provided between the inner side wall of the second limiting groove 45 and the side wall of the second limiting block 47.

[0080] The outer surface of the second adjusting ring 39 is provided with multiple sets of second toothed grooves 40 distributed in a circular interval. Inside the cavity 38, a second transmission gear 41 is rotatably arranged at a position corresponding to the second adjusting ring 39. The second transmission gear 41 meshes with the second adjusting ring 39 through the second toothed grooves 40.

[0081] A fourth motor 37 is installed on the outer surface of the first adjusting ring 25 at the position corresponding to the second transmission gear 41. The output end of the fourth motor 37 passes through the first adjusting ring 25 and is connected to the side wall of the corresponding second transmission gear 41.

[0082] The cutting assembly also includes a cutting blade 27 connected to the corresponding clamping block 44;

[0083] The first motor 13, the fourth motor 37, and the first automatic telescopic rod 26 are all electrically connected to the signal device 17.

[0084] When the yarn breaks, the fourth motor 37 is activated. The fourth motor 37 drives the second adjusting ring 39 to rotate through the second transmission gear 41, thereby causing multiple sets of clamping blocks 44 to move closer to each other and clamp the yarn. At the same time, the cutting blade 27 is driven to cut the yarn.

[0085] Example 6:

[0086] like Figure 8 , Figures 9-12 As shown, the automatic splicing mechanism for the spun yarn disclosed in Embodiment Six of the present invention has a structure that is basically the same as that in Embodiment Five, except that:

[0087] A clearance cavity 28 is provided at the center of the inner wall of the wiring chamber 3. A wiring ring 31 is rotatably arranged inside the clearance cavity 28, and a first limiting block 34 is provided on both sides of the wiring ring 31. A first limiting groove 33 is provided on the inner side wall of the clearance cavity 28 corresponding to the position of the first limiting block 34. The first limiting block 34 is rotatably arranged inside the first limiting groove 33.

[0088] The outer surface of the connecting ring 31 is provided with an annular rack 32. The interior of the relief cavity 28 is provided with a first transmission gear 30 that meshes with each other at the position corresponding to the position of the annular rack 32.

[0089] Multiple sets of spaced second automatic telescopic rods 35 are installed on the inner wall of the wiring ring 31, and the output end of each second automatic telescopic rod 35 is connected to a heating plate 36 with an arc-shaped structure.

[0090] Through the cooperation of the double-headed lead screw 12 and the slider 14, the traction head 22 and the yarn are driven into the wiring chamber 3. Then, the fourth motor 37 on the cutting assembly is started to reset the cutting blade 27. Then, through the cooperation of the first automatic telescopic rod 26 and the clamping assembly, the end of the yarn is transported to the heating plate 36. Then, the second automatic telescopic rod 35 and the heating plate 36 are started to heat the yarn and fuse the yarn end.

[0091] Specifically, this scheme involves the coordination of the front roller pair 5, drive roller pair 6, middle roller pair 7, and rear roller pair 8 to guide the yarn. Then, the second motor 20 drives the drive roller pair 6 to rotate and transport the yarn. During yarn transport, the taut yarn will push against the elastically set shelf 16, preventing the signal device 17 at the bottom of the shelf 16 from contacting the trigger plate 18. When the yarn breaks, the elastically set shelf 16 is no longer limited by the yarn, causing the signal device 17 to contact the trigger plate 18. At this time, the signal device 17 is triggered, and the second motor 20 receives the signal to stop transporting the yarn.

[0092] When the yarn breaks, the fourth motor 37 is activated. The fourth motor 37 drives the second adjusting ring 39 to rotate through the second transmission gear 41, thereby causing multiple sets of clamping blocks 44 to move closer together to clamp the yarn. At the same time, the cutting blade 27 is driven to cut the yarn. After the cutting is completed, the first motor 13 is activated. Through the cooperation of the double-headed lead screw 12 and the slider 14, the traction head 22 and the yarn are driven into the wiring chamber 3. Then, the fourth motor 37 on the cutting assembly is activated to reset the cutting blade 27. Then, through the cooperation of the first automatic telescopic rod 26 and the clamping assembly, the end of the yarn is transported to the heating plates 36. Then, the second automatic telescopic rod 35 and the heating plates 36 are activated to heat the yarn and fuse the yarn end. Then, the clamping assembly is controlled to reset, and the second motor 20 is activated again to continue transporting the yarn.
