Description

Technical Field

[0001] The utility model relates to the field of twist splicers, in particular to a device for improving the wide slot of a multi-strand yarn twist splicing cavity. Background Art

[0002] A splicer is a device that splices yarns. There are two types: air splicers and mechanical splicers. An air splicer uses a jet of compressed air to untwist the yarn ends in an untwisting tube, causing the fibers to stretch in parallel. The two yarn ends then enter a twisting tube, where they overlap in opposite directions and intermingle. A high-speed swirling air stream flows from the center of the twisting tube to the ends, twisting and connecting the yarns. The direction of the swirling air stream should align with the twist direction of the yarns. Air splicers can be used to splice single and ply yarns of various fibers, using different compressed air pressures for different yarns.

[0003] The current multi-strand yarn splicing cavity wide groove improvement device, as described in the patent announcement number CN218711161U, includes a component placement mechanism, a pneumatic splicing mechanism and a pneumatic auxiliary mechanism. The front end of the component placement mechanism is provided with a pneumatic splicing mechanism, and the back of the pneumatic splicing mechanism is connected with a pneumatic auxiliary mechanism. The pneumatic splicing mechanism includes a splicing cavity, a splicing groove and an air hole, and the front end of the splicing cavity is provided with a splicing groove, and the middle part of the splicing groove is provided with an air hole.

[0004] Regarding the above-mentioned related technologies, the inventor believes that an air hole is opened in the middle of the splicing groove, and the direction of the air hole is single, so that the direction of the compressed air jet is single, so that the fibers on each yarn head to be spliced can only be mixed with each other in one direction under the blowing of compressed air, resulting in poor stability after splicing.

A matching T-shaped plug 205 is inserted into the strip-shaped hole 204, and the T-shaped plug 205 has a through hole 206 formed therein. The through hole 206 is configured to allow a bolt to pass through, allowing the T-shaped plug 205 with a through hole 206 of different inner diameters to be replaced during installation to accommodate bolts of different sizes.

[0025] Guide bars 203 are slidably connected to both sides of the movable plate 202. Each set of guide bars 203 is fixedly connected to the connecting plate 101. The provision of the guide bars 203 can guide the sliding movement of the movable plate 202. An adjustment screw 207 is threadedly connected to one side of the interior of the movable plate 202. The adjustment screw 207 is rotatably connected to the connecting plate 101. The adjustment screw 207 is configured to drive the movable plate 202 and the T-shaped plug 205 to move left and right when rotating, thereby adjusting the lateral position of the through hole 206 to accommodate the position requirements of the different mounting bolt holes on different splicers.

[0026] Rubber bellows 208 are fixedly connected to both sides of the movable plate 202. The side of the rubber bellows 208 facing away from the movable plate 202 is fixedly connected to the connecting plate 101. Both sets of rubber bellows 208 are sleeved around the outside of the adjusting screw 207. The rubber bellows 208 shield the adjusting screw 207, reducing the possibility of yarn entanglement around the adjusting screw 207. The splicing groove 103 has an arc-shaped cross-section. The bottom of the connecting plate 101 defines a connecting groove 107, which is designed to connect to a compressed air pipe, allowing compressed air to be discharged into the connecting groove 107. A matching sealing ring 108 is installed inside the connecting groove 107, fixedly connected to the connecting plate 101. The sealing ring 108 seals the gap between the connecting plate 101 and the compressed air pipe, reducing the possibility of compressed air leakage.

[0027] A first air hole 104 is provided on one side of the inner top wall of the connecting groove 107, communicating with the splicing groove 103. The first air hole 104 is tangent to one side of the inner wall of the splicing groove 103, and the top of the first air hole 104 is arranged vertically upward, so that some of the compressed air inside the connecting groove 107 can be discharged vertically upward into the splicing groove 103 through the first air hole 104 along the tangent direction of the inner wall of the splicing groove 103. A third air hole 106 is provided on the other side of the inner top wall of the connecting groove 107, communicating with the splicing groove 103. The first air hole 104 is tangent to the other side of the inner wall of the splicing groove 103, and the end of the third air hole 106 away from the connecting groove 107 is arranged vertically downward, so that some of the compressed air inside the connecting groove 107 can be discharged vertically downward into the splicing groove 103 through the third air hole 106 along the tangent direction of the inner wall of the splicing groove 103.

[0028] A second air hole 105 is provided between the bottom wall of the splicing groove 103 and the connecting groove 107. The end of the second air hole 105 away from the connecting groove 107 is tangent to the inner bottom wall of the splicing groove 103, so that part of the compressed air inside the connecting groove 107 can be discharged horizontally into the splicing groove 103 along the tangent direction of the inner wall of the splicing groove 103 through the second air hole 105, so that the three streams of compressed air discharged into the splicing groove 103 can rotate and flow inside the splicing groove 103 through the guide of the splicing groove 103, so that the joints of the multiple strands of yarn after untwisting are twisted in a rotational manner, so that the joints of each strand can be twisted into one.

[0029] When in use, the T-shaped plug 205 that is compatible with the splicer installation position can be taken out, and then the bolt is passed through the through hole 206, and then the adjusting screw 207 is rotated so that the adjusting screw 207 can drive the movable plate 202 to slide when rotating, thereby realizing the adjustment of the lateral position of the T-shaped plug 205 and the T-shaped plug 205, and then the T-shaped plug 205 is slid inside the strip hole 204 to realize the adjustment of the longitudinal position of the T-shaped plug 205 until the bolt inside the through hole 206 is adjusted to the position relative to the screw hole on the splicer, and then the T-shaped plug 205 is fixed to the splicer with the bolt, and then the inside of the trachea connecting groove 107 is connected so that the ends of the multi-strand yarns to be twisted are placed inside the splicing groove 103 when in use. , and then the top of the splicing groove 103 is covered, and the compressed air in the air pipe is discharged into the interior of the connecting groove 107, so that the compressed air is discharged into the interior of the splicing groove 103 through the guide holes of the first air hole 104, the second air hole 105 and the third air hole 106 respectively. Since the ends of the first air hole 104, the second air hole 105 and the third air hole 106 close to the splicing groove 103 are tangent to the inner wall of the splicing groove 103, the discharged compressed air can be discharged into the interior of the splicing groove 103 along the tangential direction of the inner wall of the splicing groove 103, and rotate along the interior of the splicing groove 103 through the guide hole of the inner wall of the splicing groove 103, so that the multiple untwisted joints on the yarn are twisted in a rotational manner, so that the joints of each strand can be twisted into one.
