Description

Technical Field

[0002] Cotton cheese yarn is a common cotton yarn, mainly used in various weaving and knitting processes in the textile industry. Cotton cheese yarn is mainly made of cotton fibers, which are natural fibers and have good hygroscopicity, air permeability and softness. Production process: The production process of cotton cheese yarn includes steps such as raw cotton procurement, bale opening, carding, drawing, roving, spinning, and cheesing. In multiple processes of yarn making, a conveying structure for the yarn is required. For example, in the spinning operation, 6-8 strands of yarns introduced from multiple angles need to be guided to a parallel state, the multi-strand yarns are symmetrically distributed, and the yarns in different states need to be tensioned to the same level, and a yarn tension detection and breakage alarm device is equipped to monitor the tension of the yarn in real time. However, the thickness of the yarn will affect the conveying distance. Thicker yarns may require a larger distance to avoid extrusion and damage. In some existing yarn conveying tension adjusting structures, the distance during the guiding of multi-strand yarns is fixed, resulting in poor versatility of the yarn conveying structure and inconvenience in use.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 7, in the embodiment of the present utility model, a multi-strand yarn synchronous conveying and tensioning adjustment mechanism includes a tensioning mechanism 10. The tensioning mechanism 10 includes a bottom plate 11. Two top plates 12 are slidably connected to the top of the bottom plate 11. One side of the top plate 12 is rotatably connected to a cover plate 121 through a hinge. A plurality of limiting rods 13 are slidably connected to the top of the bottom plate 11. The top ends of the limiting rods 13 are fixedly connected to a limiting plate 131. A telescopic grid 132 is movably arranged at the bottom of the bottom plate 11. The bottom ends of the limiting rods 13 are rotatably connected to the adjacent rotation nodes of the telescopic grid 132. One end of the limiting plate 131 is slidably connected to a guiding seat 14, and the other end of the limiting plate 131 is rotatably connected to a tensioning seat 15. A driving module 16 for regulating the telescopic grid 132 is arranged at the bottom of the bottom plate 11, and a limiting module 17 for regulating a plurality of tensioning seats 15 is arranged at the top of the bottom plate 11.

[0023] Specifically, by slidably connecting a plurality of limiting rods 13 to the top of the bottom plate 11, the yarn is guided to a parallel state by the guiding seat 14. Starting the motor two 162 to drive the telescopic grid 132 can equally space regulate a plurality of limiting rods 13, which is convenient for adapting to the conveying and guiding of different types of yarn. Pushing the U-shaped frame 171 can toggle two tensioning seats 15 to rotate, tension two symmetrical yarns to the same degree, and quickly fix the yarn through the clamping of the ratchet plate 176 and the clamping rod 173. Starting the motor one 143 can drive a plurality of guiding seats 14 to move synchronously, which is convenient for adjusting the wiring position of the guiding seat 14, making the guiding of the yarn more stable and convenient to use.

[0024] Embodiment 1

[0025] As Figure 2-7 shown, in this embodiment, a regulating frame 141 is slidably connected between the two outer walls of the bottom plate 11. The regulating frame 141 penetrates through a plurality of guiding seats 14 and is slidably connected to them. One side of the bottom plate 11 is rotatably connected to a one-way lead screw 142. The one-way lead screw 142 penetrates through the regulating frame 141 and is threadedly connected to it. One end of the bottom plate 11 is fixedly connected to a motor one 143. The output end of the motor one 143 penetrates through the bottom plate 11 and is fixedly connected to the adjacent end of the one-way lead screw 142. The driving module 16 includes an L-shaped frame one 161 slidably connected to the bottom of the bottom plate 11. The L-shaped frame one 161 is rotatably connected to the adjacent rotation node of the telescopic grid 132. Two L-shaped frames two 164 are slidably connected to the bottom of the bottom plate 11. The two L-shaped frames two 164 are respectively rotatably connected to the adjacent ends of the telescopic grid 132. A bidirectional lead screw 163 is rotatably connected to the bottom of the bottom plate 11. The bidirectional lead screw 163 penetrates through the two L-shaped frames two 164. The L-shaped frame two 164 is threadedly connected to the adjacent section of the bidirectional lead screw 163. A motor two 162 is fixedly connected to the bottom of the bottom plate 11. The output end of the motor two 162 is fixedly connected to the adjacent end of the bidirectional lead screw 163.

[0026] In this embodiment, the first motor 143 is started to drive the one-way lead screw 142 to rotate. The regulation frame 141 is driven to move through the one-way lead screw 142. The regulation frame 141 drives a plurality of guiding seats 14 to move horizontally, so that the positions of the plurality of guiding seats 14 can be uniformly adjusted, which is convenient for guiding the yarn by the guiding seats 14 at appropriate positions. The middle section of the driving module 16 is limited by the rotational connection between the first L-shaped frame 161 and the telescopic grid 132. The second motor 162 is started to drive the bidirectional lead screw 163 to rotate, thereby driving the two ends of the telescopic grid 132 to move synchronously in opposite directions, so as to stretch or contract the telescopic grid 132, and the plurality of limiting rods 13 can be synchronously regulated, and the distances between the plurality of limiting rods 13 are ensured to be the same.

[0027] As Figure 1-5 shown, in this embodiment, a plurality of limiting frames 111 and a hydraulic rod 112 are fixedly connected to both sides of the bottom plate 11. A plurality of sliders 122 are fixedly connected to the outer walls of the two top plates 12 facing away from each other. The sliders 122 are slidably connected to the inside of the adjacent limiting frames 111. The output end of the hydraulic rod 112 is fixedly connected to the adjacent outer wall of the top plate 12.

[0028] During specific implementation, the sliding limit of the top plate 12 is realized by the limit of the slider 122 by the limiting frame 111. By starting the two top plates 12, the cover plate 121 can be lifted. The two cover plates 121 cooperate to cover the tops of the plurality of guiding seats 14 and the tensioning seats 15 to prevent the yarn from falling off. By starting the top plate 12, the hydraulic rod 112 can lift the top plate 12 and rotate the cover plate 121 to lean against the limiting frame 111, which is convenient for feeding and leading the yarn.

[0029] Embodiment 2

[0030] On the basis of Embodiment 1, in order to synchronously tension two symmetric yarns.

[0031] As Figure 1-6 shown, in this embodiment, a shaft rod 151 is fixedly connected to the bottom of the tensioning seat 15. The shaft rod 151 passes through the adjacent limiting plate 131 and is rotatably connected thereto. A gear 152 is fixedly sleeved at the bottom end of the shaft rod 151. The limiting module 17 includes a positioning frame 177 fixedly connected to the top of the bottom plate 11. A plurality of U-shaped frames 171 with different lengths are arranged on the top of the bottom plate 11. The U-shaped frames 171 pass through the positioning frame 177 and are slidably connected thereto. Rack bars 172 are fixedly connected to both ends of the U-shaped frame 171. The rack bars 172 are meshed with the adjacent gears 152. Clamping rods 173 are slidably connected to both ends of the U-shaped frame 171. Springs 174 are fixedly connected between the clamping rods 173 and the adjacent U-shaped frames 171. Two ratchet plates 176 are symmetrically and fixedly embedded in the top of the bottom plate 11. A plurality of clamping rods 173 are movably clamped with the adjacent ratchet plates 176. A pull rod 175 is fixedly connected between the outer walls of the two clamping rods 173 at the same height on the front side.

[0032] During specific implementation, the rotation limit of the tensioning seat 15 is achieved by limiting the shaft rod 151 through the limiting plate 131. The rotation of the tensioning seat 15 can adjust the tension degree of the yarn. The gear 152 is used to cooperate with the rack 172 to drive and limit the tensioning seat 15. The lengths of the multiple U-shaped frames 171 decrease successively from top to bottom to adapt to the fixation of the racks 172 at different positions. The heights of different gears 152 are different. The sliding U-shaped frame 171 drives the rack 172 to move, and the rotation of the tensioning seat 15 is driven by the transmission between the rack 172 and the adjacent two gears 152. For example, when pushing the uppermost U-shaped frame 171, the two outermost tensioning seats 15 are driven to rotate synchronously and in opposite directions, so as to synchronously tension the two symmetrically distributed yarns. When pushing the U-shaped frame 171 for adjustment, the ratchet plate 176 allows the clamping rod 173 to move unidirectionally and is immediately limited under the drive of the spring 174, so as to quickly limit the deflection angle of the tensioning seat 15, quickly tighten the yarn, and under the elastic action of the yarn, cooperate to fix the position of the U-shaped frame 171. The pull rod 175 can be pulled to drive the two clamping rods 173 at the same height to move upward, and the clamping rods 173 are synchronously separated from the ratchet plate 176, so as to release the limit on the U-shaped frame 171 and loosen the tension of the yarn.

[0033] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.

This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
