Description

Technical Field

[0001] This utility model relates to a crochet machine, and more particularly to a swaying and transverse movement device for the upper row of the crochet machine. Background Technology

[0002] Crochet knitting machines are a type of warp knitting machine, primarily used for producing narrow-width warp-knitted fabrics such as lace and elastic bands. Their technical features include a horizontally arranged needle bed and guide bars, vertical weft guide bars, and the use of latch needles or self-closing crochet needles to knit the warp yarns and clamp the weft yarns to form loop structures. Current technology designs independent mechanisms for the oscillation and lateral movement of crochet machines, resulting in relatively complex traditional designs, specifically regarding the oscillation and translation of the upper yarn row. There is still significant room for structural optimization to facilitate production, processing, and maintenance. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a swaying and transverse movement device for the upper row of a crochet machine.

The swaying mechanism includes a drive motor, a first wheel axle, a second wheel axle, a third wheel axle, a first transmission belt, a second transmission belt, a chain assembly, and a first eccentric shaft. The first wheel axle, the second wheel axle, and the third wheel axle are arranged in a triangular positioning layout. The drive motor and the first wheel axle are driven by the first transmission belt. The second transmission belt is synchronously driven by the first wheel axle, the second wheel axle, and the third wheel axle. The first eccentric shaft and the third wheel axle are parallel in axis and rotate synchronously. The frame is provided with a movable shaft for the upper thread row to be fitted. The first eccentric shaft drives the movable shaft to rotate through the chain assembly. The lateral movement mechanism is hinged to the upper thread row to perform a reciprocating pulling action. The upper thread row has a fitting part and a limiting contact surface that fits the movable shaft inside the fitting part.

[0015] like Figures 1-5As shown, a swaying and lateral movement device for the upper yarn row 2 of a crochet machine includes a frame 1 and an upper yarn row 2 movably mounted thereon. It also includes a swaying mechanism 13 and a lateral movement mechanism 14. The swaying mechanism 13 includes a drive motor 3, a first axle 4, a second axle 5, a third axle 6, a first transmission belt 7, a second transmission belt 8, a chain assembly 9, and a first eccentric shaft 10. The first axle 4, second axle 5, and third axle 6 are arranged in a triangular configuration. The drive motor 3 is driven by the first transmission belt 7, and the second transmission belt 8 passes through the first axle 4, second axle 5, and third axle 6. The three axles 6 provide synchronous transmission. The first eccentric shaft 10 and the third axle 6 are parallel in axis and rotate synchronously. The frame 1 is provided with a movable shaft 11 for the upper wire bar 2 to be fitted. The first eccentric shaft 10 drives the movable shaft 11 to rotate through the interlocking assembly 9. The lateral movement mechanism 14 is hinged to the upper wire bar 2 to perform reciprocating pulling action. The upper wire bar 2 has a fitting part 12 and a limiting contact surface that fits the movable shaft 11 inside the fitting part 12. The lateral movement mechanism 14 is linked with the second axle 5. The first axle 4 is linked with an interlocking mechanism, which connects to the lower wire bar, etc. Overall, the main transmission part of the swing mechanism 13 is designed on the side of the frame 1, and drives the various mechanisms to move synchronously through belt or track transmission. In this embodiment, the first axle 4 mainly drives the lower wire bar and the tool holder to move, which is a mature technology. The second axle 5 drives the upper wire bar 2 to move laterally. The design of the first eccentric shaft 10 eliminates the need for an overly complex design, and the swing of the upper wire bar 2 does not require an excessively large rotation angle or swing angle. The upper row 2 has a certain weight, and its relative position can be maintained by fitting it onto the movable shaft 11. During production, the rows of yarn are pulled, so structural stability can be ensured without an overly complex structural design. An anti-slip surface can be designed on the inside of the fitting 12 to improve stability when needed, but this is not the only limitation. The overall design is suitable for the neatly arranged multi-axis structure of a crochet machine, while also meeting the needs of transmission and synchronous movement.

[0016] A pressure roller 15 is also provided on the frame 1 between the first axle 4 and the second axle 5. The pressure roller 15 is located on the line connecting the first axle 4 and the second axle 5 and on the outside of the second transmission belt 8. The pressure roller 15 strengthens the second transmission belt 8 to fit tightly against the second axle 5, thereby improving transmission efficiency and stability.

[0017] The interlocking assembly 9 includes a first sleeve rod 16, a second sleeve rod 17, a fixed sleeve rod 18, and a movable sleeve rod 19. The movable sleeve rod 19 is rotatably mounted on the frame 1. The two ends of the first sleeve rod 16 are respectively sleeved on the first eccentric shaft 10 and the movable sleeve rod 19. The two ends of the fixed sleeve rod 18 are respectively fixedly connected to the movable shaft 11 and the second sleeve rod 17. The second sleeve rod 17 is sleeved on the movable sleeve rod 19. The first sleeve rod 16 drives the movable sleeve rod 19, the second sleeve rod 17, the fixed sleeve rod 18, the movable shaft 11, and the upper wire guide 2 in sequence through eccentric rotation. The eccentric rotation of one end of the first sleeve rod 16 pulls the movable sleeve rod 19 to rotate, and the movable sleeve rod 19 drives the second sleeve rod 17. The second sleeve rod 17 is relatively fixed to the fixed sleeve rod 18, which can drive the upper wire guide 2 to swing along a relatively non-geometric path, which is more adaptable to the lead wire layout of the actual production line. At the same time, it can also be adjusted as needed for convenient operation.

[0018] The lateral movement mechanism 14 includes a second eccentric shaft, a lifting wheel seat 20, a lifting rod 21, a swing arm 22, and a connecting rod 23. The swing arm 22 has a right-angle structure. The second eccentric shaft and the second wheel axle 5 rotate synchronously with parallel axes. The lifting wheel seat 20 is sleeved on the second eccentric shaft for linkage. The lifting rod 21 is limited and movablely assembled with the lifting wheel seat 20. The lifting rod 21 pulls one end of the swing arm 22, and the other end of the swing arm 22 pulls the connecting rod 23. The connecting rod 23 is hinged to the upper cable tray 2. Output is also achieved through eccentric motion, converting rotational motion into nonlinear motion, which can be further converted into near-linear motion through limitation. In this embodiment, the spatial layout is optimized, with the lifting rod 21 driving subsequent traction and the left-right reciprocating movement of the upper cable tray 2. It should be noted that the lifting wheel seat 20 is provided with a waist hole 24 for the limited assembly of the lifting rod 21. The lifting wheel seat 20 follows the second eccentric shaft in an eccentric motion, but it does not rotate; it only moves within a vertical plane. The waist hole 24 is designed for easy installation and positioning adjustment. In particular, since the lifting wheel seat 20 only performs unidirectional traction, it needs to be installed on both sides of the frame 1 to facilitate left and right movement. The waist hole 24 is the layout of this embodiment. Alternatively, the lifting rod 21 can be equipped with limiting members on both sides of the waist hole 24 to facilitate direct bidirectional traction; however, this will not be elaborated upon or limited further here.
