Description

Technical Field

[0001] This utility model relates to the field of cotton loom technology, specifically to a reed anti-wear mechanism for a cotton loom. Background Technology

[0002] The core function of the reed on the loom is to precisely adjust the warp yarn distribution through the fixed gap of the reed teeth, so as to ensure that the fabric width and warp density meet the process requirements. During the weaving process, the reed swings with the reed seat, pressing the weft yarn introduced into the shed tightly into the weave, and interweaving with the warp yarn to form a dense fabric.

[0003] Chinese patent document CN214004956U discloses a steel reed for a rapier loom, comprising an upper beam, a lower beam, end beams, and reed blades. The upper and lower beams are arranged in parallel, and the two ends of the upper beam and the two ends of the lower beam are connected by end beams. Reed blades are arranged between the upper and lower beams, and at least one reed blade has a width different from the widths of the other reed blades. This utility model has a simple structure and is easy to use. After weft-beating with the steel reed with its concave and convex weft-beating surface, the weft yarns in the fabric exhibit a regular curved shape, giving the fabric a three-dimensional appearance and creating a unique style.

[0004] However, in the above solution, the reeds of the cotton loom experience varying degrees of wear during use. When a reed is damaged, the entire reed needs to be disassembled and replaced, which reduces the service life of the reed. Improvement and optimization are needed. Utility Model Content

[0017] The mounting holes 3 on the boss 2 are used for the installation of the steel reed frame 1 and the cotton weaving machine. Wear-resistant pads 5 are provided on both sides of the reed 4 to improve the wear resistance of the reed 4.

[0018] The positioning inserts 6 in the auxiliary components are symmetrically connected and arranged at both ends of the reed 4. The inner walls of both sides of the reed frame 1 are symmetrically and equidistantly provided with grooves 7. The positioning inserts 6 are movably fitted into the grooves 7. The side walls of the reed frame 1 are symmetrically snapped together with two U-shaped limiting plates 9.

[0019] The positioning insert 6 is movably fitted into the groove 7 and is used for positioning and installing the reed 4 to achieve its arrangement inside the steel reed frame 1.

[0020] The steel reed frame 1 has trapezoidal grooves 8 at equal intervals at the four corners of its side wall. The U-shaped limiting plate 9 has trapezoidal sliders 10 symmetrically connected on both sides of its side wall. The trapezoidal sliders 10 are movably engaged in the trapezoidal grooves 8. The groove of the U-shaped limiting plate 9 is set at an angle. The end wall of the U-shaped limiting plate 9 is engaged and fitted with the end wall of the positioning insert 6.

[0021] The trapezoidal slider 10 is movably engaged within the trapezoidal slide groove 8, ensuring the stable up-and-down movement of the U-shaped limiting plate 9. The end wall of the U-shaped limiting plate 9 engages with the end wall of the positioning insert 6, thereby ensuring the stability of the reed 4 during installation.

[0022] The steel reed frame 1 is symmetrically connected to the two end walls of the frame. The end of the fixed platform 11 is provided with a threaded hole 12. The side wall of the U-shaped limiting plate 9 is connected to an L-shaped plate 13. The end wall of the L-shaped plate 13 is rotatably provided with a knob 14. The bottom end of the knob 14 is connected to a screw 15 that is threaded to the threaded hole 12.

[0023] The screw 15 is threadedly connected to the threaded hole 12 to push the U-shaped limiting plate 9 up and down and fix its position.

[0024] The L-shaped plate 13 has symmetrical slots 16 on both side walls, and the fixed platform 11 has symmetrical limit grooves 17 on both side walls. A U-shaped insert plate 18 is snapped onto the side end of the fixed platform 11. Limit sliders 19 are symmetrically connected to the inner walls of both sides of the U-shaped insert plate 18, and the limit sliders 19 are movably snapped into the limit grooves 17. The end of the U-shaped insert plate 18 is inserted into the slot 16. A buckle groove 20 is formed on the side wall of the U-shaped insert plate 18, and the bottom wall of the groove of the U-shaped insert plate 18 is snapped into contact with the side wall of the fixed platform 11. An elastic buckle 21 is connected to the side wall of the fixed platform 11, and the elastic buckle 21 is snapped into the buckle groove 20.

[0025] The limiting slider 19 is movable and snapped into the limiting groove 17, so that the U-shaped insert plate 18 can move stably horizontally.

The elastic buckle 21 is snapped into the buckle groove 20 to fix the position of the U-shaped insert plate 18.

[0026] Working principle: Rotating knob 14 controls screw 15 to separate from threaded hole 12. At this time, trapezoidal slider 10 moves to the end of trapezoidal groove 8, and the end wall of screw 15 abuts against the opening of threaded hole 12, thus exposing groove 7. Positioning insert 6 is then inserted into groove 7 to complete the positioning and installation of reed 4. Afterwards, rotating knob 14 in the opposite direction controls screw 15 to screw into threaded hole 12, thereby driving U-shaped limiting plate 9 to move towards the inner frame of reed frame 1. During the U-shaped limiting plate 9 process, the side of positioning insert 6 contacts the inclined surface of U-shaped limiting plate 9 and moves along its inclined surface to ensure that the positioning insert 6 is stably inserted into groove 7 until knob 14 and the end of fixed platform 11 are engaged. When the U-shaped limiting plate 9 and the positioning insert 6 are engaged, the end wall of the U-shaped limiting plate 9 abuts against the outside of the positioning insert 6. Then, the limiting slider 19 moves along the limiting groove 17 until the bottom wall of the U-shaped insert 18 groove engages with the side wall of the fixing platform 11. At this time, the elastic buckle 21 and the buckle groove 20 engage to fix the position of the U-shaped insert 18, so that the end of the U-shaped insert 18 is inserted into the slot 16 to help fix the position of the U-shaped limiting plate 9. The operation is simple. The wear-resistant pad 5 is set to improve the wear resistance of the reed 4. When a single reed 4 in the steel reed is worn during the use of the cotton loom, it can be easily disassembled and replaced individually to extend the service life of the steel reed.
