Description

Technical Field

[0001] The utility model relates to the technical field of warping, in particular to a wire pressing plate device which is convenient for tight pressing. Background Art

[0002] Warping is an important step in weaving. Its purpose is to arrange a certain number of cheese yarns into a certain width according to the designed length, and wind them parallely onto the warping beam or weaving beam to prepare for the warp yarn system that constitutes the fabric. In the process of the yarn being led out from the creel, the yarn passing through the splitting reed and the fixed width reed needs to be pressed by the wire pressing plate to reduce the occurrence of yarn band diffusion, silk thread disorder, etc.

[0003] For example, a Chinese patent document with publication number CN217895859U discloses a warping machine wire pressing plate for polyester-cotton fabric production, comprising a warping machine table, a first pressing plate, a second pressing plate and two cushioning layers, wherein the second pressing plate is located above the first pressing plate, and the two cushioning layers are respectively fixedly connected to the top of the first pressing plate and the bottom of the second pressing plate, and the opposite sides of the two cushioning layers are in contact with each other, and a bin body is fixedly installed on the top of the warping machine table, and an adjustment mechanism is arranged inside the bin body to drive the first pressing plate to adjust the height, and the adjustment mechanism includes a threaded rod.

[0004] It can be seen from the above disclosed content that in the above technical scheme, the height of the first pressure plate is adjusted by the setting adjustment mechanism, and the self-locking function of the worm and the worm wheel can maintain the stability of the first pressure plate after the adjustment of the height of the first pressure plate is completed, and it is not easy to move, thereby improving the product quality of the polyester-cotton cloth, thereby having the advantage of good movement stability and convenient use. After the first pressure plate contacts the second pressure plate, the pressure between the two on the yarn mainly depends on the gravity of the second pressure plate itself. However, the friction force generated between the sleeve and the vertical rod is opposite to the direction of the gravity of the second pressure plate, which reduces the resultant force acting on the yarn, which easily leads to insufficient compression of the yarn, causing the yarn to spread.

[0018] like Figures 1 to 3 As shown, the utility model discloses a wire pressing plate device which is convenient for tight pressing, including a warping machine table 1, the warping machine table 1 is provided with symmetrical columns 2, a pressing plate 3 is provided between adjacent columns 2, the pressing plate 3 includes a top pressing plate 31 and a bottom pressing plate 32, a mounting cavity 21 is provided in the column 2, a driving component is provided in the mounting cavity 21, the top pressing plate 31 and the bottom pressing plate 32 are driven by the arranged driving component to move toward each other, so that the top pressing plate 31 and the bottom pressing plate 32 can respectively press the two sides of the yarn, thereby ensuring the tightness of the yarn pressing, and thus preventing the yarn from spreading during the warping process.

[0019] In this embodiment, the specific structure of the drive assembly includes a bidirectional lead screw 41, both ends of the bidirectional lead screw 41 serve as connecting ends 411, and the connecting ends 411 are rotatably connected to the installation cavity 21. The two ends of the bidirectional lead screw 41 are respectively provided with a top connecting sleeve 42 and a bottom connecting sleeve 43 that are threadedly matched with the two ends of the bidirectional lead screw 41. The column 2 is located on the side facing the top pressure plate 31 and the bottom pressure plate 32 and is provided with an opening 22 that is connected to the installation cavity 21. The top connecting sleeve 42 and the bottom connecting sleeve 43 are respectively fixed with a top connecting rod 44 and a bottom connecting rod 45 that are adapted to the opening 22. The top connecting rod 44 and the bottom connecting rod 45 extend outward through the opening 22 and are respectively connected to the top pressure plate 31 and the bottom pressure plate 32. The top pressure plate 31 and the bottom pressure plate 32 are connected by driving the two-way screw 41 to rotate, so that the top connecting sleeve 42 and the bottom connecting sleeve 43, which are respectively mounted on the two ends of the two-way screw 41 and form a threaded fit, can move toward each other with the rotation of the two-way screw 41, thereby driving the top pressure plate 31 and the bottom pressure plate 32 to move toward each other, and completing the compression of the yarn, wherein the top connecting rod 44 and the bottom connecting rod 45 are adapted to the opening 22, that is, the outer walls of the top connecting rod 44 and the bottom connecting rod 45 can abut against the side walls of the column 2, thereby ensuring that the top connecting sleeve 42 and the bottom connecting sleeve 43 can move stably along the line-laying of the two-way screw 41 to prevent self-rotation with the rotation of the two-way screw 41.

[0020] In this embodiment, a horizontally arranged rotating shaft 5 is further provided below the bottom pressure plate 32, and both ends of the rotating shaft 5 are respectively rotatably connected to the mounting cavities 21 of the columns 2 on both sides, and a worm gear 6 is fixedly mounted on the outer periphery of the connecting end 411, and a worm screw 7 is connected to the end of the rotating shaft 5, which meshes with the worm gear 6 and can form a transmission cooperation between the two. The worm screw 7 meshes with the worm gear 6, so that the two-way lead screws 41 on both sides can be driven to rotate simultaneously by rotating the rotating shaft 5, thereby completing the synchronous movement of the top pressure plate 31 and the bottom pressure plate 32, so that the yarn can be compressed more quickly, and the top connecting sleeve 42 and the bottom connecting sleeve 43 respectively cooperate with the threads formed at the two ends of the two-way lead screw 41, and the meshing between the worm screw 7 and the worm gear 6 have self-locking ability, which can further improve the stability of the top pressure plate 31 and the bottom pressure plate 32 after movement.

The sliding rod 91 is coupled to the slide groove 8 and can constitute a sliding fit between the two. The splicing part 9 is located on the side facing away from the pressure plate 3 and extends outward as a mounting surface. A cushion 10 is fixed to the mounting surface. By arranging the cushion 10 on the mounting surface, the wear and elongation of the yarn when the yarn is compressed can be reduced to prevent it from breaking, and by extending the mounting surface outward, it can be ensured that the cushion 10 is in full contact with the yarn. In addition, during long-term use, the cushion 10 will crack due to aging. At this time, through the set slide groove 8 and sliding rod 91, the sliding rod 91 can slide in or out of the slide groove 8, and the detachable connection between the splicing part 9 and the pressure plate 3 can be realized, thereby completing the replacement of the cushion 10 to ensure the performance of the cushion 10 during long-term use.

[0022] In this embodiment, first threaded holes 11 connected to the slide groove 8 are further provided on both sides of the pressure plate 3, and second threaded holes 12 opposite to the first threaded holes 11 are provided on the sliding rod 91. The second threaded hole 12 and the first threaded hole 11 are fixed by a locking member 13. The locking member 13 that can form a threaded match with the first threaded hole 11 and the second threaded hole 12 can be screwed in to fix the splicing part 9 to ensure the stability of the connection between the splicing part 9 and the pressure plate 3, and the sliding rod 91 is in an "L" shape, so that after the sliding rod 91 slides into the slide groove 8, it can limit the left and right directions of the splicing part 9, thereby further improving the stability of the connection between the splicing part 9 and the pressure plate 3.

[0023] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention.
