Traditional weft selection and weft laying devices mostly use mechanical yarn clamping structures, which have problems such as weak yarn clamping, easy yarn loosening, high yarn breakage rate, and slow mechanism response. Especially under high-speed operation, stability and reliability are significantly reduced. In existing technologies, the coordination between pressing and clamping yarns is poor, which easily leads to yarn displacement or missed clamping, causing weaving defects. Utility Model Content

Multiple wire clamping components are evenly arranged in the transverse direction at the bottom of the wire clamping plate. The wire clamping assembly includes a pair of wire clamping arms, each of which is rotatably mounted on a wire clamping rotating seat.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-10 The weft selection and weft laying trolley includes a trolley assembly 03, which is slidably mounted on a sliding frame 01. The trolley assembly 03 includes a frame 1, which consists of an upper plate 11 and two side plates 12. The side plates 12 are vertically connected to the two sides of the upper plate 11. Between the two side plates 12, a pressing rod 6, a first rotating rod 7, and a second rotating rod 8 are rotatably arranged from front to back. A thread clamping mechanism 5 is arranged on the side plate 12 in front of the pressing rod 6. A thread pressing frame 2 is rotatably arranged on the surface of the side plate 12 away from the other side. A thread pressing plate 3 is horizontally arranged between the two thread pressing frames 2. A pressing rod swinging mechanism 4 is arranged at both ends of the pressing rod 6. The thread clamping mechanism 5 is used to clamp the yarn.

[0018] The upper plate 11 has a timing belt pressure plate 13 in the middle of its upper surface. Multiple first rollers 14 are symmetrically and horizontally arranged on both sides of the timing belt pressure plate 13. Second rollers 15 are symmetrically and vertically arranged on both sides of the upper plate 11. Eccentric wheels 16 are rotatably arranged below the second rollers 15 on the side plates 12. The timing belt pressure plate 13 facilitates belt drive displacement in conjunction with the timing belt assembly 02. The timing belt assembly 2 is driven by a motor at one end of the sliding frame 01. The driving wheel on the sliding frame 01 and the timing belt on the driven wheel are driven by the synchronous belt. The first rollers 14 and the second rollers 15 are fixed to the frame 1 by bearings and pins.

[0019] In addition, the wire pressing frame 2 includes a first swing arm 21, a second swing arm 22, and a rotating arm 23. The first swing arm 21 is connected to the two ends of the second rotating rod 8. The end of the first swing arm 21 away from the second rotating rod 8 is rotatably connected to the second swing arm 22. A wire pressing plate 3 is installed between the ends of the second swing arms 22 away from the first swing arm 21. The wire pressing plate 3 is located above the wire clamping mechanism 5. The rotating arm 23 is rotatably connected to the middle of the second swing arm 22. The end of the rotating arm 23 away from the second swing arm 22 is rotatably set at both ends of the pressing rod 6. The first swing arm 21 is used to cooperate with the rotating arm 23 to rotate, so that the second swing arm 22 swings down and presses the wire pressing plate 3 down.

[0020] The wire clamping mechanism 5 includes a wire clamping plate connecting rod 51, which is located in the middle of the first rotating rod 7 and the second rotating rod 8. A wire clamping plate 52 is horizontally arranged on the front side of the wire clamping plate connecting rod 51. The two ends of the wire clamping plate 52 are connected to the side plates 12 on both sides. Multiple wire clamping components 53 are evenly arranged in the transverse direction at the bottom of the wire clamping plate 52. The wire clamping plate 52 is used to install the wire clamping components 53.

[0021] Furthermore, the wire clamping assembly 53 includes a pair of wire clamping arms 532, both of which are rotatably mounted on the wire clamping rotating seat 531. The wire clamping rotating seat 531 is located at the bottom of the wire clamping plate 52. A wire clamping spring 533 is provided between the wire clamping arms 532 on both sides. A wire clamping end 5321 is provided at the front end of the wire clamping arm 532, and a limiting end 5322 is provided at the tail end of the wire clamping arm 532. A wire clamping spring 533 is provided between the limiting ends 5322, and the limiting ends 5322 of the adjacent wire clamping assemblies 53 are used to be squeezed by the extrusion rod 6, and the wire clamping spring 533 is used to contract.

[0022] Meanwhile, multiple pressing holes 31 are evenly arranged in the horizontal direction at the bottom of the front side plate of the pressing plate 3. The pressing holes 31 are aligned with the position of the clamping assembly 53 below. The pressing holes 31 are used to press down the yarn so that the clamping arm 532 can hold the yarn.

[0023] The extrusion rod swing mechanism 4 includes a swing frame 41, a tension spring connecting block 42, a first tension spring 43, and a tension spring connecting rod 44. The tension spring connecting block 42 is connected to both ends of the extrusion rod 6. The tension spring connecting rod 44 is located on the surface of the side plate 12 between the first swing arm 21 and the extrusion rod 6. The tension spring connecting rod 44 and the tension spring connecting block 42 are connected and pulled by the first tension spring 43. The swing frame 41 includes a first rotating block 411, which is connected to both ends of the extrusion rod 6. A second rotating block 412 is rotatably mounted on the first rotating block 411. A third rotating block 413 is rotatably connected to the other end of the second rotating block 412 away from the first rotating block 411. The third rotating block 413 is connected to both ends of the first rotating rod 7. The first tension spring 43 is used to reset the rotating extrusion rod 6.

[0024] In addition, multiple extrusion posts 61 are evenly arranged along the transverse direction on the extrusion rod 6. The extrusion posts 61 are used to extrude the limiting end 5322 and the wire clamping arm 532, thereby opening the wire clamping arm 532.

[0025] Meanwhile, a first limiting arm 71 is provided at one end of the first rotating rod 7, and a first limiting roller 72 is rotatably provided at the end of the first limiting arm 71 away from the first rotating rod 7. The first limiting arm 71 is easily held by the mechanism, thereby causing the pressing rod 6 to rotate.

[0026] Among them, the second rotating rod 8 is symmetrically provided with tension spring connecting seats 83 on the rod body between the side plates 12 on both sides. The tension spring connecting seats 83 are connected to the second tension spring 84. The end of the second tension spring 84 away from the tension spring connecting seat 83 is connected to the upper plate 11. The second tension spring 84 enables the second rotating rod 8 to be reset when it rotates.

[0027] In this embodiment, when it is necessary to clamp the yarn from one side of the processing frame to the other side of the processing frame, the synchronous belt assembly 02 drives the synchronous belt pressure plate 13 through belt drive, so that the first roller 14 and the second roller 15 cooperate with the eccentric wheel 16 to make the carriage assembly 03 move on the sliding frame 01. When clamping the yarn, the first limiting swing arm 71 is rotated first, thereby driving the first rotating rod 7 to rotate. The third rotating block 413 rotates and pushes the first rotating block 411 to rotate through the second rotating block 412, thereby causing the extrusion rod 6 to rotate. The extrusion column 61 swings forward and the extrusion column 61 extrudes the limiting ends 5322 on both sides, so that the front clamping end 5321 of the originally closed clamping arm 532 opens, and the clamping spring 533 contracts at the same time.

[0028] Furthermore, as the compression rod 6 rotates, the tension spring connecting block 42 pulls the first tension spring 43, causing the first tension spring 43 to deform.

[0029] While the first limiting arm 71 is rotated, the second limiting roller 82 contacts the upper surface of the limiting top block 04 on one side of the sliding frame 01. The limiting top block 04 abuts against the second limiting roller 82, causing the second limiting arm 81 to rotate. This causes the second rotating rod 8 to rotate, and the rotation of the second rotating rod 8 causes the first arm 21 to deflect forward. With the cooperation of the rotating arm 23, the second arms 22 on both sides push and drive the pressure plate 3 to press down. The pressure hole 31 presses the yarn, making it easier for the yarn to be clamped by the clamping end 5321. When the second rotating rod 8 rotates, it drives the tension spring connecting seat 83 to rotate, and the tension spring connecting seat 83 pulls the second tension spring 84.

[0030] After the first limiting arm 71 and the second limiting arm 81 are no longer limited, the first tension spring 43 and the second tension spring 84 release their elastic potential energy to reset, thereby resetting the second rotating rod 8 and the first rotating rod 7. The pressure plate 3 resets and no longer presses the yarn, the squeezing column 61 no longer squeezes the limiting end 5322, the clamping arm 532 closes, and clamps the yarn. At this time, the trolley displacement drives the yarn out, and after it is in place, the yarn is released by swinging the first limiting arm 71 and the second limiting arm 81.

[0031] In this invention, by setting the wire clamping mechanism 5 and the wire pressing plate 3 to work together, the precise clamping and holding of the yarn is achieved, effectively preventing the yarn from shifting or loosening during high-speed transport. The wire pressing frame 2, in conjunction with the squeezing rod swing mechanism 4, makes the wire pressing and opening / closing actions coordinated and consistent, with a fast response speed. The wire clamping assembly 53 is equipped with a wire clamping spring 533 and a limiting end 5322 structure. The mechanical pushing and closing is achieved through the squeezing column 61 on the squeezing rod 6, and the clamping force is stable and reliable. The first tension spring 43 and the second tension spring 84 are set for the reset of the squeezing rod 6 and the second rotating rod 8, respectively, to ensure that the initial state is quickly restored after the operation cycle is completed.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
