Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a leno heddle capable of being reset with follow-up. Background Art

[0002] The weaving of real silk is inseparable from the twisted edge structure. The so-called twisted edge is a protective structure on both sides of the silk cloth to prevent the yarn from falling off. The rapier loom is an edgeless weaving machine, and has strict requirements on the tightness and effect of the twisted edge. The twisted edge is composed of two transfer warps and one twisted warp entangled with each other. The two transfer warps are controlled by the base heddle, one rises and the other falls to form the loom. When weaving, the weft yarn passes through the twisted edge continuously through the weft insertion and beating-up, and this cycle continues. When a transfer warp rises, a twisted warp is controlled by the twisted heddle, and the twisted warp rises and is wrapped around the transfer warp. The two rear heddles continue to rise and fall, and the twisted warp continues to wrap around the transfer warp, forming an S-shaped structure. When the weft yarn passes through it, it is locked to form a twisted edge.

[0003] Currently available leno heddle, such as a kimono twisted heddle drive structure with Chinese patent publication number CN106757648A, includes a leno heddle, an iron heddle, a harness, a spring and a harness. The leno heddle is composed of two steel heddles arranged on the left and right, and the iron heddle is inserted between the two steel heddles to connect the two steel heddles; two harnesses are arranged behind the leno heddle, and the upper and lower ends of the heddle are each provided with an interface, the upper end is tied by a harness and fixed upward on the flower plate handle, and the lower end is fixed downward on the wood by a spring.

[0004] However, the leno healds described above are controlled by springs. As the riding healds follow the base healds up and down, they are subject to additional tension from the springs. This creates significant resistance as the base healds rise, preventing the machine from operating at full power. The bases holding the springs are connected to a large number of springs and carry a heavy load. This can lead to damage to both the bases and the springs over time, making the springs vulnerable to wear. The springs also experience a strong impact when returning to their original position during descent, leading to significant vibration and noise. This can also damage machine components.

[0005] Based on the above issues, this case arose. Utility Model Content

[0012] (3) Beneficial effects

[0013] The utility model provides a leno heddle with follow-up reset, which has the following beneficial effects:

[0014] 1. The leno heddle with follow-up reset of the twirled heddle adopts the follower of the present application to replace the existing spring. When any base heddle moves up or down, the twirled heddle on the follower can be linked to run synchronously. Since the base heddle and the twirled heddle are not subjected to the tension of the spring, their resistance and load are reduced, and the impact force and vibration when the twirled heddle is reset are also small. The machine can run at a faster speed than the existing speed, which not only has high work efficiency but also prevents parts from being damaged easily. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model provides a leno heddle with follow-up reset, such as Figure 1As shown, it includes a pair of basic heddles 1, a twisted heddles, a follower 3, and a swing arm 5. The upper and lower ends of the pair of basic heddles 1 are used to connect the heddles frames, and the heddles frames are driven to rise and fall by the power assembly on the loom, which is consistent with the principle of the existing loom. This application abandons the spring connecting the bottom of the twisted heddles to the base and adopts a new design scheme, which is as follows.

[0020] The upper and lower ends of the basic heald 1 are mounted on the upper and lower crossbars of the heald frame via the heald frame hooks 2. The follower 3 is composed of two plates connected by two upward limiting shafts 8. The two plates of the follower 3 are provided with through slots 4 for the passage of straightened strands. The straightened strands are used to mount the stranded strands, which are arranged by riding on the straightened strands. The straightened strands and stranded strands are both existing products, and the mounting method is consistent with the existing arrangement method. The stranded strands are provided with holes for the passage of stranded warps. The warps pass through the gap between the pair of basic healds 1. The space between the two plates of the follower 3 allows the passage of a pair of basic healds 1 and can slide vertically. Two upward limiting shafts 8 are provided on both sides of the bottom of the follower 3, and the two upward limiting shafts 8 are respectively located on the outside of the pair of basic healds 1. The lower part of the pair of basic healds 1 is provided with an upward support platform 9 extending outward at an angle. When the basic healds 1 ascend, the upward support platform 9 acts on the upward limiting shafts 8 and drives the follower 3 to rise. The top of the swing arm 5 is hinged to the center of the top of the follower 3. The hinge axis separates the left and right base heddles 1. The bottom of the swing arm 5 is located between the pair of base heddles 1. A downward support platform 7 is provided at the bottom of each pair of base heddles 1, extending outward at a gradient. The bottom of the swing arm 5 is provided with a downward limit shaft 6, which is supported on the downward support platform 7. When the base heddles 1 descend, the downward support platform 7 acts on the downward limit shaft 6, driving the follower 3 downward. Two downward limit shafts 6 are arranged in parallel, so that when either base heddle 1 ascends, the downward limit shaft 6 can slide with the other base heddle 1, preventing hard friction between the follower 3 and the base heddles 1.

[0021] Working principle: Figure 2 As shown, when located Figure 2 When the base heddle 1 on the left side rises, the upward support platform 9 on the left base heddle 1 presses against the upward limit shaft 8 on the left side of the follower 3, so that it drives the follower 3 and the heddle to rise. At the same time, the downward limit shaft 6 at the bottom end of the swing arm 5 slides into the space below the downward support platform 7 of the left base heddle 1.

[0022] like Figure 3As shown, when the left basic heald 1 is descending and the right basic heald 1 is ascending, before the ascending support platform 9 of the right basic heald 1 does not contact the right ascending limit shaft 8, the descending support platform 7 on the left basic heald 1 presses the descending limit shaft 6 to link the follower 3 and the twisted heald downward; when the ascending support platform 9 of the right basic heald 1 contacts the right ascending limit shaft 8, the descending limit shaft 6 slides along the left descending support platform 7 into the descending support platform 7 of the right basic heald 1, and then the ascending support platform 9 of the right basic heald 1 is pressed against the ascending limit shaft 8 on the right side of the follower 3, so that it drives the follower 3 and the twisted heald to rise. When the right basic heald 1 descends, it is consistent with the principle of the left basic heald 1 descending, and the left and right basic healds 1 circulate up and down in this way.
