Description

Technical Field

[0001] The invention relates to the technical field of leading parts of textile printing and dyeing machinery, in particular to a mending heddle of an intelligent loom. Background Art

[0002] Healds are the main components used in modern weaving machines to pull the warp yarns. During the normal operation of the weaving machine, it is inevitable that a few healds will break. In order to avoid long equipment downtime due to repairs, the current repair method is generally to use a patching heald. Unlike the fully enclosed heald ends of the heald, the heald ends of the patching heald are semi-enclosed. Its general structure is as follows Figure 1 As shown, the heald loop (11) can be quickly hung on the heald bar. However, due to the opening of the heald loop, it is easy to fall off the heald bar. For this reason, the application with publication number CN109652889A discloses another heald loop structure. Its general structure is as follows Figure 2 As shown, the heald loops are limited from falling off the heald bar by the limiting cooperation of the raised portion (12) and the recessed portion (13). In this context, in order to overcome the problem of heald loops easily falling off the heald bar due to the opening of the heald loops, the present application proposes a third heald loop structure for mending healds. Summary of the Invention

[0003] The technical problem to be solved by the present invention is how to overcome the problem that the heddle loops are easily dropped from the heddle due to the openings, and provides a mending heddle for an intelligent loom that can be stably hung on the heddle.

[0004] The technical solution of the present invention is a patching heddle for an intelligent loom, comprising a first heddle rod, a second heddle rod, and a third heddle rod connected in sequence in a straight line. The first and third heddle rods are hollow, and the ends of the first and third heddle rods are each provided with a heddle loop that is semi-enclosed and open as a whole. The loops are provided with an L-shaped rotating rod. The ends of the second heddle rod are respectively provided with a connecting shaft that passes through the first and third heddle rods and connects to the rotating rod. The middle of the second heddle rod is provided with a brown eye. The ends of the second heddle rod are each provided with a receiving groove extending along the length of the second heddle rod and located on one side of the connecting shaft. The receiving groove is provided with a V-shaped positioning spring, the ends of which extend into the first heddle rod or the third heddle rod and elastically abut the inner wall of the first heddle rod or the third heddle rod. After the loops are attached to the heddle bar, rotating the second heddle rod can drive the rotating rod to rotate, thereby forming a fully enclosed closed state with the loops, and the closed state is maintained by the positioning spring.

[0005] As an embodiment, the two accommodating grooves provided at the end of the second heald rod include two accommodating grooves, the two accommodating grooves are respectively located on both sides of the connecting shaft, and the positioning springs are provided in the two accommodating grooves.

[0006] As an embodiment, the accommodating groove is a thin sheet-shaped square groove.

[0007] As an embodiment, the brown eyes are elongated.

[0008] As an embodiment, the heddle ear includes an elongated main ear hole, and also includes a first side ear hole and a second side ear hole connected on both sides of the main ear hole and are elongated, the first side ear hole and the second side ear hole are shorter than the main ear hole and form a convex hole in the heddle ear; the first side ear hole is connected to the side wall of the heddle ear, the second side ear hole is connected to the opening of the heddle ear, the bottom of the rotating rod is connected to the connecting shaft, and the side of the rotating rod is located in the first side ear hole when the heddle ear is in an open state, and is located in the second side ear hole when the heddle ear is in a closed state.

[0009] As an embodiment, the length and width of the side portion of the rotating rod are respectively the same as the length and width of the first side ear hole, and when the side portion of the rotating rod is located in the first side ear hole, the first side ear hole is filled.

[0010] As an embodiment, the length and width of the side portion of the rotating rod are respectively the same as the length and width of the second side ear hole, and when the side portion of the rotating rod is located in the second side ear hole, the second side ear hole is filled.

[0011] As an embodiment, the thickness of the rotating rod is the same as the thickness of the heald loop.

[0012] The present invention has the following advantages over the prior art: after the heald loop is attached to the heald bar, the second heald rod is rotated, causing the L-shaped rotating rod to move to the opening of the heald loop as the second heald rod rotates, forming a fully enclosed state with the heald loop, thereby preventing the heald from falling off the heald bar. Furthermore, the elastic force of the positioning spring maintains the fully enclosed state between the rotating rod and the heald loop. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The above and other embodiments and advantages of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0022] In one embodiment, Figure 3-7 shown.

[0023] The intelligent heald repairing device provided in this embodiment includes a first heald rod 1, a second heald rod 2, and a third heald rod 3 connected in a straight line. The first heald rod 1 and the third heald rod 3 are hollow, and the ends of the first heald rod 1 and the third heald rod 3 are each provided with a heald loop 4 that is semi-enclosed and open as a whole. The heald loop 4 is provided with an "L"-shaped rotating rod 5. The ends of the second heald rod 2 are respectively provided with a connecting shaft 6 that passes through the first heald rod 1 and the third heald rod 3 and connects to the rotating rod 5. The middle of the second heald rod 2 is provided with a brown eye 7. The ends of the second heald rod 2 are provided with a receiving groove 8 that is opened along the length of the second heald rod 2 and is located on one side of the connecting shaft 6. The receiving groove 8 is provided with a "V"-shaped positioning spring 9 that extends into the first heald rod 1 or the third heald rod 3 at both ends and elastically abuts against the inner wall of the first heald rod 1 or the third heald rod 3. Among them, after the heald loop 4 is hung on the heald bar, rotating the second heald rod 2 can drive the rotating rod 5 to rotate to form a fully enclosed closed state with the heald loop 4, and the closed state is maintained by the positioning spring 9.

[0024] In this embodiment, the structure of the heald loop 4 of the patching heald is similar to the structure of the traditional heald loop 11, and the whole is in a semi-enclosed open state, so it can be quickly hung on the heald bar. Compared with reinstalling the heald, using a patching heald can reduce equipment downtime. In order to prevent the patching heald from falling off the heald bar, the structure of the heald loop 4 of the patching heald can be quickly converted from a semi-enclosed open state to a fully enclosed closed state. Specifically, after the heald loop 4 is hung on the heald bar, the second heald rod 2 is rotated so that the "L"-shaped rotating rod 5 moves to the opening of the heald loop 4 as the second heald rod 2 rotates, forming a fully enclosed closed state with the heald loop 4, thereby preventing the patching heald from falling off the heald bar. During the rotation of the second heald rod 2, the two ends of the positioning spring 9 change from elastically contacting the thickness inner wall of the first heald rod 1 or the third heald rod 3, to elastically contacting the width inner wall of the first heald rod 1 or the third heald rod 3, and then to elastically contacting the thickness inner wall of the first heald rod 1 or the third heald rod 3. During this process, the positioning spring 9 is compressed and then expanded, and finally the rotating rod 5 and the heald eye 4 are maintained in a fully enclosed closed state by the elastic force of the positioning spring 9.

[0025] In one embodiment, Figure 5 shown.

[0026] The intelligent loom's supplementary heddle provided in this embodiment includes two accommodating grooves 8 provided at the end of the second heddle rod 2. The two accommodating grooves 8 are respectively located on both sides of the connecting shaft 6. Positioning springs 9 are provided in both accommodating grooves 8.

[0027] In this embodiment, two locating springs 9 are provided, each end of which elastically contacts the inner wall of the first heald rod 1 or the third heald rod 3. This prevents the second heald rod 2 from shifting relative to the first heald rod 1 or the third heald rod 3 during operation. Because each locating spring 9 is located on one side of the connecting shaft 6 relative to the connecting shaft 6, both ends of each locating spring 9 are biased toward one side within the first heald rod 1 or the third heald rod 3. Therefore, while the locating springs 9 can prevent the second heald rod 2 from tilting relative to the first heald rod 1 or the third heald rod 3, it is inevitable that it will shift. Providing two locating springs 9 can overcome this problem.

[0028] In one embodiment, Figure 6-7 shown.

[0029] The patching heddle of the intelligent loom provided in this embodiment includes an elongated main heddle hole 41, and also includes elongated first and second side heddle holes 42 and 43 connected to either side of the main heddle hole 41. The first and second side heddle holes 42 and 43 are shorter than the main heddle hole 41 and form convex holes within the heddle hole 4. The first side heddle hole 42 connects to the side wall of the heddle hole 4, and the second side heddle hole 43 connects to the opening of the heddle hole 4. The bottom of the rotating rod 5 is connected to the connecting shaft 6. The side portion of the rotating rod 5 is located within the first side heddle hole 42 when the heddle hole 4 is open, and within the second side heddle hole 43 when the heddle hole 4 is closed. In addition, the length and width of the side portion of the rotating rod 5 are respectively the same as the length and width of the first side heddle hole 42. When the side portion of the rotating rod 5 is located within the first side heddle hole 42, it fills the first side heddle hole 42. In addition, the length and width of the side of the rotating rod 5 are respectively the same as the length and width of the second side ear hole 43 . When the side of the rotating rod 5 is located in the second side ear hole 43 , the second side ear hole 43 is filled.

[0030] In this embodiment, the structure of the heald loop 4 is specifically defined. After the heald loop 4 is attached to the heald bar, the second heald rod 2 is rotated, causing the L-shaped turning rod 5 to move to the opening of the heald loop 4, that is, from the first side opening 42 to the second side opening 43. This creates a fully enclosed state between the L-shaped turning rod 5 and the heald loop 4, preventing the heald from falling off the heald bar. Furthermore, because the length and width of the side portions of the turning rod 5 are identical to those of the first side opening 42 and the second side opening 43, respectively, the turning rod 5 can completely fill the first side opening 42 or the second side opening 43, preventing the threads from snagging. Similarly, in another embodiment, the turning rod 5 can be made the same thickness as the heald loop 4 to achieve the same effect.

[0031] The above specific embodiments further illustrate the purpose of the invention, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. In particular, it is pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
