This structure is simple and stable, enabling precise control of the heddle movement and improving the effect and quality of warp heddle weaving. In the pay-off mechanism, the pay-off roller and the reciprocating screw are linked by gear transmission, allowing the yarn to be neatly arranged as the moving block moves on the reciprocating screw during the pay-off process. This avoids yarn tangling and knotting problems, improving production efficiency.

Description

Technical Field

[0001] This utility model relates to the field of reflective detection technology, and more specifically, to a device for heddle weaving process on rapier looms. Background Technology

[0002] Rapier looms are widely used equipment in the textile industry. During the weaving process, the heddle weaving technique can achieve unique fabric textures and structures to meet different market demands. However, existing rapier looms have many problems when performing heddle weaving. Therefore, there is an urgent need for a device for the heddle weaving process on rapier looms that is simple in structure, stable in operation, provides neat yarn feeding, and can efficiently coordinate with the heddle movement.

[0003] On the one hand, traditional heddle mechanisms are complex in structure and their driving methods are not stable enough, making it difficult to precisely control the movement of the heddles. This results in poor warp heddle effect, affecting the quality and appearance of the fabric. For example, in some devices, the poor movement precision of the heddles can easily lead to problems such as uneven warp weaving and inaccurate heddle angles. On the other hand, existing pay-off devices often result in uneven yarn arrangement during the pay-off process, easily leading to tangling and knotting. This not only reduces production efficiency but also increases manual intervention and maintenance costs. Moreover, the pay-off speed is not well coordinated with the heddle mechanism, making it impossible to achieve an efficient and stable weaving process. Utility Model Content

[0004] The purpose of this invention is to provide a device for the heddle weaving process of a rapier loom, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a device for heddle weaving process of rapier loom, comprising a base, a heddle mechanism installed in the middle of the base, the heddle mechanism comprising at least one set of first heddle wires and second heddle wires, a pay-off box installed at the top of the base, a pay-off mechanism installed inside the pay-off box, and the first heddle wires and second heddle wires passing through the pay-off box and connecting to the pay-off mechanism.

[0018] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0019] Please see Figure 1-3 According to an embodiment of the present invention, an apparatus for heddle weaving process of a rapier loom includes a base 1, a heddle mechanism 2 installed in the middle of the base 1, the heddle mechanism 2 including at least one set of first heddle wires 3 and second heddle wires 4, a pay-off box 5 installed at the top of the base 1, a pay-off mechanism 6 installed inside the pay-off box 5, and the first heddle wires 3 and second heddle wires 4 passing through the pay-off box 5 and connecting to the pay-off mechanism 6.

[0020] The base 1 provides a supporting foundation for the entire device used in the heddle weaving process of a rapier loom, and is used to install the heddle mechanism 2 and the pay-off box 5. The heddle mechanism 2 realizes the heddle movement of the heddles in the rapier loom heddle weaving process, and includes a first heddle 3 and a second heddle 4. The first heddle 3 is a component of the heddle mechanism 2, participating in the heddle movement and guiding the warp yarns during weaving. The second heddle 4 is a component of the heddle mechanism 2, cooperating with the first heddle 3 to complete the warp heddle. The pay-off box 5 houses the pay-off mechanism 6, providing a relatively stable space for the yarn to be released. The pay-off mechanism 6 is responsible for releasing the yarn, ensuring an orderly supply of yarn, and cooperates with the heddle mechanism 2 to complete the weaving process.

[0021] In this embodiment, the heave mechanism 2 includes a motor 7 fixedly installed by a support column. The output end of the motor 7 is equipped with a rotating shaft 8, which includes a first eccentric wheel 9 and a second eccentric wheel 10.

[0022] In this design, motor 7 serves as the power source for the heave mechanism 2, driving the rotating shaft 8 to rotate. The rotating shaft 8 transmits the power from motor 7 to the first eccentric wheel 9 and the second eccentric wheel 10, causing them to rotate. The first eccentric wheel 9 is mounted on the rotating shaft 8, and during rotation, it engages with the roller 11 to cause the swing bracket 12 to swing.

[0023] The second eccentric wheel 10 is mounted on the rotating shaft 8 and works in conjunction with the first eccentric wheel 9. When rotating, it drives the swing bracket 12 to swing through cooperation with the roller 11.

[0024] In this embodiment, the bottom of the first eccentric wheel 9 and the second eccentric wheel 10 are both connected to rollers 11. The rollers 11 are mounted on the swing bracket 12 through a rotating component. The end of the swing bracket 12 is mounted on the first support plate 13 through a rotating component. Guide holes 14 are provided through both ends of the swing bracket 12. The bottom end of the swing bracket 12 away from the first support plate 13 is fixedly connected to the base 1 with a first spring 15.

[0025] The roller 11 is rolledly connected to the first eccentric wheel 9 and the second eccentric wheel 10, converting the rotation of the eccentric wheels into the swing of the swing bracket 12. The swing bracket 12 swings under the drive of the roller 11, thereby driving the first heddle wire 3 and the second heddle wire 4 to achieve heddle winding. The first support plate 1 provides a rotational support point for the swing bracket 12, enabling it to swing stably. Guide holes 14 are formed at both ends of the swing bracket 12 to guide the movement direction of the first heddle wire 3 and the second heddle wire 4. The first spring 15 connects the swing bracket 12 and the base 1, serving to buffer and reset the swing bracket 12.

[0026] In this embodiment, the wire feeding mechanism 6 includes a second support plate 16 and a third support plate 17 inside the wire feeding box 5. A wire feeding roller 18 is rotatably mounted on the second support plate 16, and a reciprocating lead screw 19 is rotatably mounted on the third support plate 17.

[0027] The second support plate 16 is used to rotatably mount the pay-off roller 18, providing support for it. The third support plate 17 is used to rotatably mount the reciprocating screw 19, providing support for it as well. The pay-off roller 18 stores the yarn and releases it during rotation. The reciprocating screw 19 and the pay-off roller 18 are linked by gear transmission, causing the moving block 23 to reciprocate, ensuring that the yarn is released neatly.

[0028] In this embodiment, a first gear 20 is installed at one end of the wire feeding roller 18, a second gear 21 is installed at the same end of the reciprocating screw 19 and meshes with the first gear 20, a slide bar 22 is installed below the second support plate 16, and a moving block 23 is threadedly connected to the reciprocating screw 19. A wire feeding hole 24 is opened in the middle of the moving block 23.

[0029] The first gear 20 is installed at one end of the pay-off roller 18 and meshes with the second gear 21 to drive the pay-off roller 18 and the reciprocating screw 19. The second gear 21 is installed at one end of the reciprocating screw 19 and meshes with the first gear 20 to drive the pay-off roller 18 and the reciprocating screw 19. The slide bar 22 is installed below the second support plate 16 to guide the movement of the moving block 23. The moving block 23 is threadedly connected to the reciprocating screw 19, and the pay-off hole 24 in the middle guides the yarn, making reciprocating motion with the rotation of the reciprocating screw 19 to keep the yarn neatly arranged. The pay-off hole 24 is opened in the middle of the moving block 23 to guide the yarn through and ensure the direction of the yarn during the pay-off process.

[0030] In practical applications, the motor 7 is turned on, driving the rotating shaft 8 to rotate. The first eccentric wheel 9 and the second eccentric wheel 10 mounted on the rotating shaft 8 begin to rotate synchronously. During the rotation of the first eccentric wheel 9 and the second eccentric wheel 10, the rollers 11, which are rolled and connected to their bottoms, are subjected to the action of the eccentric wheels. Since the rollers 11 are mounted on the swing bracket 12 through rotating parts, the rotation of the eccentric wheels is converted into the swing of the swing bracket 12 around the first support plate 13. During the swing, the guide holes 14 through both ends of the swing bracket 12 guide the first heddle 3 and the second heddle 4 to move along a specific trajectory, realizing the twisting motion of the warp yarns. At the same time, the first spring 15 plays a buffering role when the swing bracket 12 swings, and helps the swing bracket 12 to return to its original position after it has moved to a certain position, ensuring the stability and periodicity of the twisting motion. The pay-off mechanism works simultaneously with the twisting mechanism 2. Because the first gear 20 installed at one end of the pay-off roller 18 meshes with the second gear 21 installed at the same end of the reciprocating screw 19, when the yarn is released from the pay-off roller 18, the rotation of the pay-off roller 18, through the transmission of the first gear 20 and the second gear 21, drives the reciprocating screw 19 to rotate. The moving block 23, threadedly connected to the reciprocating screw 19, reciprocates along the slide bar 22 under the action of the rotation of the reciprocating screw 19. The slide bar 22 provides guidance for the movement of the moving block 23, ensuring the stability of the movement of the moving block 23. The yarn passes through the pay-off hole 24 opened in the middle of the moving block 23. With the reciprocating movement of the moving block 23, the yarn can be released neatly, avoiding yarn tangling or confusion, ensuring that the yarn is supplied in an orderly manner to the heddle mechanism 2, where it cooperates with the warp yarns to complete weaving.
