Description

Technical Field

[0001] This utility model relates to a crochet machine, and more particularly to a crochet machine thread linkage mechanism. Background Technology

[0002] Crochet knitting machines are a type of warp knitting machine, mainly used to produce narrow-width warp-knitted fabrics such as lace and elastic bands. Their technical features include a horizontally configured 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. Crochet knitting machines can process both synthetic and natural yarns and can be equipped with composite needles to meet different needs. Jiangsu Xinzeqi Machinery Co., Ltd. (established in 2003) is one of the major manufacturers, specializing in crochet knitting machines and other textile machinery. As of 2010, the technology of domestic crochet knitting machines varied greatly, with high-end products relying on imports. Manufacturers are gradually upgrading towards computerization and full automation. Existing products feature independently designed yarn rows and cutter heads, resulting in a relatively complex and crowded structure, with room for improvement in spatial layout. In particular, the cyclical motion of the cutter head scraping the yarn and the longitudinal movement of the yarn frame lack a simple, interconnected layout. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a linkage mechanism for the yarn arrangement of a crochet machine.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hook knitting machine thread linkage mechanism, including a drive shaft, an eccentric cam, a linkage component, a thread frame, a sliding assembly, a locking assembly, and a cutter holder. The drive shaft and the eccentric cam are linked and rotate synchronously. One end of the linkage component is the driving part, and the other end is the driven part. The driving part is sleeved on the eccentric cam and rotates eccentrically. The driven part pushes the thread frame to make a vertically limited movement through the sliding assembly. The linkage component has a linkage part in the middle section, and the linkage part is hinged to the cutter holder through the locking assembly.

[0005] A transmission wheel is fixedly connected to the drive shaft, and the eccentric cam is connected to the transmission wheel by a belt drive.

[0010] The width between the linkage part and the driving part of the linkage component gradually narrows from both ends toward the middle, and the width between the linkage part and the driven part of the linkage component gradually narrows from both ends toward the middle.

[0019] Example 1: As Figures 1-4As shown, a crochet machine thread linkage mechanism includes a drive shaft 1, an eccentric cam 2, a linkage component 3, a thread frame 4, a sliding assembly, a chain assembly, and a cutter holder 5. The drive shaft 1 and the eccentric cam 2 are linked and rotate synchronously. One end of the linkage component 3 is a driving part 6, and the other end is a driven part 7. The driving part 6 is sleeved on the eccentric cam 2 and rotates eccentrically. The driven part 7 pushes the thread frame 4 to move vertically to a limited position through the sliding assembly. The linkage component 3 has a linkage part 8 in the middle section, which is hinged to the cutter holder 5 through the chain assembly. The eccentric cam 2 is mounted on the frame via a shaft connection. The motor outputs the drive shaft 1 and drives the eccentric cam 2 to rotate. The output of the eccentric cam 2 causes one end of the linkage component 3 to rotate relative to the eccentric cam 2. The other end of the linkage component 3, in this embodiment, is restricted by the sliding assembly and moves up and down relative to the eccentric cam 4, thus moving the thread frame 4 up and down. The design rationally utilizes the spatial characteristics of the multi-axis crochet machine, resulting in efficient and reliable multi-axis movement that meets design and usage requirements.

[0020] A transmission wheel 9 is fixedly connected to the drive shaft 1, and the eccentric cam 2 is connected to the transmission wheel 9 by a belt drive. In this embodiment, a track-type transmission belt is used to improve the transmission ratio, enhance service life, and reduce maintenance needs. The interlocking assembly includes a driving member 10 and an interlocking seat 11. The interlocking seat 11 is fixedly connected to the tool holder 5, and the two ends of the driving member 10 are respectively hinged to the interlocking seat 11 and the linkage part 8. The movement of the tool holder 5 does not need to strictly specify a path. In this embodiment, the interlocking assembly is given sufficient freedom, allowing it to naturally scrape along the tension, extension, or bending deformation direction of the wire, making it more flexible to use. The wire does not need to pass through the tool holder 5, which simplifies the structural design and makes it more ingenious. Both ends of the driving member 10 are provided with through driving holes 12. The design of the driving holes 12 mainly indicates that the connection is limited by a shaft or fastener, which facilitates disassembly and use.

[0021] The sliding assembly includes a slide block 13 and a slide column 14. The slide column 14 serves as a stationary reference frame, and a limiting sliding fit exists between the slide column 14 and the slide block 13. The slide block 13 is hinged to the driven part 7. The slide column 14 can be fixed to the frame via other accessories, and a connecting accessory is also provided between the slide block 13 and the wire frame 4. The slide block 13 and the driven part 7 are hinged. Taking this embodiment as an example, the slide block 13 is provided with a movable shaft for the driven part 7 to be fitted, which satisfies the needs of hinge and support, and further enables vertical movement.

[0022] The width between the linkage part 8 and the driving part 6 of the linkage component 3 gradually narrows from both ends towards the middle, and the width between the linkage part 8 and the driven part 7 of the linkage component 3 also gradually narrows from both ends towards the middle. This reduces material usage and operating costs while ensuring structural strength, and also improves the aesthetics. Several linearly arranged openings 15 are provided between the driving part 6 and the linkage part 8, and between the driven part 7 and the linkage part 8. The design of the openings 15 increases structural complexity, which is beneficial for improving structural strength. At the same time, the circular structure of the openings 15 can effectively offset some stress. The eccentric cam 2 is provided with an eccentric shaft 16 parallel to its axis. The driving part 6 is sleeved on the eccentric shaft 16. This is a specific installation structure, which will not be elaborated or limited further here. The cutter holder 5 is also provided with a cutting blade 17, and includes a fixed yarn separating plate 18 as a stationary reference system. The cutting blade 17 performs an interlacing cutting action relative to the fixed yarn separating plate 18. The cutting blade 17 moves back and forth relative to the fixed yarn separating plate 18 via a linkage action, cutting off the loops and turning them into yarn. This process will not be elaborated or limited further here.

[0023] Example 2: Unlike Example 1, the sliding assembly includes a slide block and a slide column. The slide block serves as a stationary reference frame, and the slide column is in a limiting sliding fit with the slide block. The slide column is hinged to the driven part. The slide block is mounted on the frame and has a sliding hole for the slide column to slide in. The slide column reciprocates along the sliding hole or along the axial direction, and is hinged to the driven part. The movement of the driven part propels the axial movement of the slide column, further driving the wire frame to move. Further elaboration and limitations are not provided here.
