Description

Technical Field

[0001] This utility model relates to the field of weft knitting jacquard fabric weaving technology, and in particular to a weft knitting jacquard fabric weaving equipment. Background Technology

[0002] Weft knitting jacquard weaving technology is widely used in the textile industry due to its ability to weave complex patterns and rich textures. During the continuous high-speed weaving process of weft knitting jacquard looms, intense friction occurs between key moving parts such as knitting needles and sinkers and the yarn, as well as between the yarns themselves. This friction inevitably leads to a significant increase in the temperature of the mechanical parts and the yarn in the contact area. If the continuously accumulated heat is not dissipated in a timely and effective manner, it will be directly conducted to the fabric surface that is being formed, affecting the stability of the weaving and the quality of the final fabric surface. Therefore, developing a weft knitting jacquard weaving equipment that can actively regulate the temperature of key areas during the weaving process is crucial for improving product quality and production efficiency.

[0003] Existing weft knitting jacquard looms mainly rely on a triangular track system to drive the knitting needles to move up and down in a regular manner. With the help of components such as sinkers and yarn guides, the yarn is completed in the process of looping, padding, bending, looping and pulling. Its core technology lies in the precise control of the movement trajectory of the jacquard knitting needles through an electronic needle selection device, thereby realizing the knitting of complex patterns. The heat dissipation design of equipment typically focuses on ensuring the cooling of the main drive system, such as the spindle, bearings, and motor. For example, the operating temperature of these core components is reduced by fan airflow or lubricating oil circulation. For the local frictional heat generated at the weaving points and on the fabric itself being woven, existing equipment mainly relies on the natural convection of ambient air for passive heat dissipation. However, in the production practice of high-speed, high-density jacquard weaving, the above-mentioned technology relying on passive air cooling has obvious limitations: the heat generated by the high-speed friction between mechanical parts and yarns during the weaving process continues to accumulate, causing the temperature of the fabric and yarns near the weaving points to rise significantly. This temperature rise will cause the yarns, especially thermoplastic synthetic fibers, to undergo thermal expansion or even local softening, thereby interfering with the normal loop formation process. Ultimately, it will form "weft shrinkage" defects on the fabric surface that are difficult to eliminate, such as skewed or uneven loops, which seriously affect the appearance flatness, dimensional stability, and overall quality of the fabric. Therefore, a weft-knitted jacquard weaving equipment is proposed to solve the above problems. Utility Model Content

[0032] Reference Figures 1-4The cleaning mechanism includes a cleaning roller 11, which serves as a rotating actuator for the cleaning action and supports a cleaning brush 12. The cleaning roller 11 is rotatably connected inside the frame 1. The cleaning brush 12 is fixedly connected to the side wall of the cleaning roller 11. The cleaning brush 12 works in conjunction with the cleaning roller 11 to perform a rotating cleaning motion, effectively removing fiber fragments and impurities accumulated on the surface of the fabric below the rotating column 15. The cleaning brush 12 consists of boar bristles and a base, effectively removing impurities. A housing 14 is installed on the side wall of the frame 1, which encloses and protects the motor 13, providing a safe operating environment. The motor 13 is installed inside the housing 14, providing rotational power to the cleaning roller 11 and driving the cleaning action.

A cover 23 is installed on the top of the water tank 5, which seals the top opening of the water tank 5, preventing foreign objects from entering, liquid evaporation, and allowing for the addition of water. The side wall of the frame 1 is fixedly connected to... The frame 1 has a rotating column 15 and a support platform 16 fixedly connected to its side wall. The support platform 16 is used to fix and support the upper adjusting rod 17, providing a stable installation base. The top of the support platform 16 is fixedly connected to the adjusting rod 17, which is used to connect the support platform 16 and the tray 19 and allows for a certain angle adjustment. The adjusting rod 17 is rotatably connected to a ball shaft 18.

[0033] Working principle: When using this equipment, first add the water source required for weaving and cooling to the water tank 5, place the yarn to be woven on the knitting needle 22, and after starting the equipment, the knitting needle 22 weaves the yarn on the weaving board 2. At this time, start the water pump 6, and the water pump 6 pumps the spray water into the hose 7 and delivers it into the fixed pipe 8 and then into the water pipe 9. The water is then sprayed out through the nozzle 10 to cool the fabric surface and yarn. After the equipment has been running for a period of time, the fabric surface becomes wet and drips water due to continuous spraying. The water flows into the collection box 4 through the drip groove 3. When the water level in the collection box 4 reaches a certain level, open the valve 21, and the water flows back into the water tank 5 through the collection pipe 20.

[0034] After the fabric is woven on the weaving board 2, the single layer of fabric moves downward and is stretched between the rotating columns 15. It is then bundled up by the rotating columns 15. During the operation of the rotating columns 15, the motor 13 drives the cleaning roller 11 to rotate, causing the cleaning brush 12 on the cleaning roller 11 to rotate synchronously and rub against the rotating columns 15. The brush cleans the fabric according to the angle at which it is rolled up downward, removing the scraps and threads attached to the surface of the fabric.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
