Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, specifically to a monofilament heddle and jacquard loom. Background Technology

[0002] In the field of textile machinery, heddles are key components for controlling warp yarn opening, and their structural design directly affects weaving efficiency and fabric quality. In jacquard looms, to reduce friction between the heddles and warp yarns and avoid snagging accidents, the heddle structure disclosed in patent CN110685049A can be used. Its guide wire typically uses flat wire with a rectangular cross-section, and slits are directly punched into the narrower surface of this type of wire for subsequent gluing and fixing of the heddle eye. However, in actual manufacturing, the inventors discovered significant technological challenges with this processing method: Due to the limited width of the flat wire, the positioning accuracy of the equipment is extremely high when punching and cutting. Even slight deviations or misalignments in the cutting position can easily lead to inaccurate heddle eye installation positions, which in turn affects the overall symmetry of the heddle wires and the shape consistency of all heddle wires in the loom. This increases instability in the production process and reduces the batch manufacturing efficiency and finished product consistency of the heddle wires. Utility Model Content

[0003] This utility model addresses the problem of unstable stamping and cutting quality of existing flat yarns by providing a continuous yarn, monofilament heddle, and jacquard weaving machine. The specific technical solution is as follows: A type of through wire includes a flat wire body, wherein the flat wire body needs to have a narrow side of the punch cut to form a V-shaped groove, and the length direction of the V-shaped groove is consistent with the length direction of the flat wire body.

[0004] Furthermore, the V-groove is symmetrical about the center plane A of the flat wire body, and the center plane A is perpendicular to the narrow side.

[0005] Preferably, the included angle α of the V-groove satisfies: 90°≤α≤110°.

[0006] Preferably, the flat wire body is symmetrical about the central plane B, and the central plane B is parallel to the narrow side.

[0007] A monofilament heddle includes: a through wire, a flat wire body formed by stamping into a stamped flat wire, and a cut in the stamped flat wire connected to the heddle eye.

[0008] Preferably, the stamped flat wire forms a straight fixed section at the cut, and the fixed section is connected to the heddle eye.

[0009] Preferably, the inner surface of the fixed section overlaps with the side surface of the eyelet to form an adhesive connection.

[0010] A jacquard loom comprising monofilament heddles.

[0011] As can be seen from the above technical solution, this utility model has the following beneficial effects: This invention forms a V-groove on the narrow side of the flat wire body, which guides the stamping cutter of the stamping equipment to stamp the flat wire body along the V-groove. This ensures that the stamping trajectory of the stamping cutter does not deviate, and when the position of the V-groove relative to the flat wire body is consistent, the contact position between the stamping cutter and the flat wire body is consistent. This ensures that the cut position formed on the flat wire body is consistent, and the cut quality is maintained stably, thereby improving the batch manufacturing efficiency and finished product consistency of heddle wire.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0016] Example 1 like Figure 1 As shown, this embodiment is a through wire, which includes a flat wire body 1. The flat wire body 1 needs to form a V-shaped groove 2 on the narrow side of the punch cut 52. The length direction of the V-shaped groove 2 is consistent with the length direction of the flat wire body 1.

[0017] Specifically, as is known from common knowledge in this field, round wire is rolled into flat wire. The side of the flat wire body 1 consists of narrow side and wide side. The total area of ​​the narrow side is smaller than the total area of ​​the wide side. The upper and lower sides in the figure are narrow side, and the left and right sides in the figure are wide side. The operator uses the stamping tool 6 of the stamping equipment to stamp and form a cut 52 on the narrow side to place the heddle eye 54. The figure is a schematic diagram of the outline of the stamping tool 6, and the arrow indicates the stamping direction of the stamping tool 6.

[0018] Secondly, the narrow side is rolled by V-shaped rolls to form a V-groove 2. The length direction of the V-groove 2 is the same as the length direction of the flat wire body 1. The V-groove 2 is composed of inclined sides, which can constrain the position of the stamping tool 6 used by the stamping equipment for stamping the cut 52 relative to the narrow side, so that it accurately contacts the narrow side, thereby enabling it to accurately perform stamping operations on the narrow side, avoiding the stamping tool 6 of the stamping equipment from shifting relative to the narrow side during the stamping process, and thus ensuring that the cut 52 in the loom is in the same position relative to the flat wire body 1.

[0019] Furthermore, the V-groove 2 is symmetrical about the center plane A3 of the flat wire body 1, and the center plane A3 is perpendicular to the narrow side.

[0020] Specifically, the center plane A3 is a vertical plane, the flat wire body 1 is symmetrical about the center plane A3, and the V-groove 2 is symmetrical about the center plane A3, so that the lowest point of the V-groove 2 intersects with the center plane A3. Thus, the V-groove 2 can guide the stamping cutter 6 of the stamping equipment to move to its lowest point, that is, to intersect with the center plane A3. This makes the cuts 52 symmetrical about the center plane A3, and thus makes their positions relative to the narrow side the same, improving the quality of the stamping cuts 52 of the flat wire body 1.

[0021] Furthermore, the included angle α of the V-groove 2 satisfies: 90°≤α≤110°.

[0022] Specifically, the size of the included angle α represents the guiding and fixing effect of the V-groove 2 on the stamping cutter 6 of the stamping equipment and the stress concentration at the lowest point of the V-groove 2 during the stamping process. When α < 90°, the stress concentration at the lowest point of the V-groove 2 is severe when the stamping cutter 6 stamps along the V-groove 2, which can easily lead to cracking at the lowest point of the V-groove 2 during the stamping process, resulting in defects such as burrs. These defects can easily cause snagging of the yarn and reduce the quality of the cut 52. When α > 110°, the guiding and fixing effect of the V-groove 2 on the stamping cutter 6 is reduced. During the stamping process of the stamping cutter 6 on the flat wire body 1, the stamping path of the stamping cutter 6 is prone to deviate, causing the position of the cut 52 relative to the flat wire body 1 to shift, thus reducing the quality of the cut 52. Preferably, when α = 100°, the V-groove 2 can stably guide and fix the stamping cutter 6. During the stamping process of the stamping cutter 6, the stress concentration at the lowest point of the V-groove 2 is alleviated, and cracking accidents are less likely to occur.

[0023] Furthermore, the flat wire body 1 is symmetrical about the central plane B4, and the central plane B4 is parallel to the narrow side.

[0024] Specifically, the center plane B4 is a horizontal plane, parallel to the narrow side and perpendicular to the wide side; secondly, the V-groove 2 is formed on the narrow side at the upper and lower positions of the flat wire body 1, so that the stamping tool 6 of the stamping equipment can simultaneously stamp the flat wire body 51 at the V-groove 2, reducing the stamping stroke of the single-sided stamping tool 6, thereby reducing the path deviation of the single-sided stamping tool 6 during the stamping process, and at the same time alleviating the stress concentration at the lowest point of the V-groove 2 during the stamping process, preventing it from cracking and improving the quality of the cut 52.

[0025] Example 2 like Figure 2 As shown, this embodiment 2 is a monofilament heddle wire, which includes: the through wire of embodiment 1, the flat wire body 1 is formed into a stamped flat wire 51 by stamping, and the cut 52 formed in the stamped flat wire 51 is connected to the heddle eye 54.

[0026] Specifically, the V-groove 2 guides the fixed stamping cutter 6 to perform stamping operations on the flat wire body 1, dividing it into two parts along the center plane A3 at its middle position, thereby forming a stamped flat wire 51 with a cut 52. The cross-sections at both ends of the middle position are still rectangular, and the separated area in the middle position is the area where the cut 52 is located. The operator places the heddle eye 54 inside, so that the heddle eye 54 is fixedly connected to the cut 52, thereby fixing the position of the heddle eye 54 relative to the stamped flat wire 51, thus forming a monofilament heddle with a consistent shape.

[0027] Furthermore, the stamped flat wire 51 forms a straight fixed section 53 at the cut 52, and the fixed section 53 is connected to the heddle eye 54.

[0028] Specifically, a cut 52 is formed in the middle of the stamped flat wire 51. The cut 52 has a hexagonal structure with pointed ends and a parallel structure in the middle, forming a straight fixed section 53. The heddle has a hexagonal structure with pointed ends forming chamfers and a parallel structure in the middle. Secondly, the length direction of the fixed section 53 is consistent with the length direction of the heddle 54 and the length direction of the stamped flat wire 51. The length of the fixed section 53 is not less than the length of the parallel section of the heddle 54, so that the parallel section of the heddle 54 can be completely fixedly connected to the fixed section 53.

[0029] like Figure 3 As shown, the inner side of the fixed section 53 overlaps with the side of the eyelet 54 to form an adhesive connection.

[0030] Specifically, the inner side of the fixed section 53 is a parallel side, and the side to which the heddle eye 54 is connected is the outer side of the parallel section. The outer side of the parallel section is a parallel side, so that the inner side of the fixed section 53 can completely overlap with the outer side of the parallel section of the heddle eye 54, and then be fixedly connected by adhesive, ensuring that the bonding area between the heddle eye 54 and the cut 52 is maximized, thereby increasing its bonding strength.

[0031] Example 3 This embodiment three is a jacquard loom, which includes the monofilament heddles of embodiment two. The position of the heddle eye 54 in the monofilament heddles relative to the stamped flat wire 51 is fixed and centered, so that the consistency of all the monofilament heddles in this embodiment three is improved, thereby improving the consistency of its finished products.
