Description

Technical Field

[0001] This utility model relates to the field of knitted tape processing technology, specifically to a surface treatment device for knitted tape with anti-pilling function. Background Technology

[0002] Knitted tape, with its softness, elasticity, and decorative properties, is widely used in clothing, bags, and industrial fields. However, pilling on its surface remains a major pain point affecting product quality and user experience. Singeing, as a mature physical anti-pilling process, effectively removes easily entangled lint by burning the fabric surface at high temperatures, thus reducing the likelihood of pilling. However, with the diversification of market demand for knitted tape products, traditional singeing equipment is no longer sufficient to meet the industry's requirements for refined and efficient production.

[0003] Today, knitted tape comes in a wide variety of materials and specifications, ranging from natural fibers to synthetic fibers, and from thin and soft to thick and strong. These products differ significantly in performance and form. However, existing singeing equipment has a rigid structure, and the method for adjusting the distance between the hot roller and the knitted tape is rudimentary, relying heavily on manual experience. This imprecise adjustment method makes it difficult for the equipment to adapt to the processing needs of different types of knitted tape: with thin knitted tape, improper control of the hot roller distance can easily cause excessive damage to the fabric, leading to carbonization and embrittlement; while when processing thicker materials, excessive distance often results in loose fibers remaining, significantly reducing the anti-pilling effect and ultimately affecting product qualification rate and stability.

[0004] Meanwhile, traditional equipment lacks an effective depth detection mechanism, making it impossible for operators to promptly grasp the actual distance between the heated roller and the knitting tape. This not only significantly increases the difficulty and time cost of equipment debugging but also results in inconsistent singeing effects across different batches of products, making standardized production difficult. In the current textile industry, where demands for product quality and production efficiency are constantly rising, the low production efficiency and resource waste caused by insufficient equipment adjustment capabilities and lack of detection feedback severely restrict enterprises' market competitiveness and sustainable development.

[0005] Therefore, it is urgent to develop a surface treatment device for knitted ribbons with flexible adjustment capabilities and precise positioning. This device needs to be able to quickly and accurately adjust processing parameters according to the characteristics of different types of knitted ribbons, ensuring a stable and reliable singeing process, thereby effectively improving the quality of knitted ribbon products and promoting the advancement of textile processing technology towards intelligence and flexibility.

[0054] Working Principle: The knitted tape to be processed enters through the feed inlet of the device housing 1 and is stably pulled and guided by two sets of guide rollers 2. The guide rollers 2, with their precise roller surface curvature and friction coefficient design, ensure that the knitted tape maintains constant tension and a linear motion trajectory in the horizontal direction, providing a stable foundation for subsequent singeing. During this process, the travel speed and tension of the knitted tape can be preset and adjusted according to the material characteristics to avoid uneven singeing caused by fabric looseness or tightness. After guiding, the knitted tape enters the singeing process. The arc-shaped heating head 4, as the core processing component, has its arc-shaped heating plate 6 heated by heating resistance wires within the structural block 7. The heating resistance wires achieve rapid heating and precise temperature control through an intelligent temperature control system, ensuring uniform temperature distribution on the surface of the arc-shaped heating plate 6 and maintaining it within a suitable singeing temperature range. Simultaneously, the horizontal position adjustment of the arc-shaped heating head 4 is driven by the adjustable depth component 3. After receiving commands from the control system, the servo motor 12 drives the lead screw 11 to rotate. Due to the threaded transmission relationship between the lead screw 11 and the lead screw moving block 13, the lead screw moving block 13 moves horizontally along the axis of the lead screw 11. The motion base block 8 is fixedly connected to the lead screw moving block 13, driving the connected structural block 7 and the arc-shaped hot plate 6 to move synchronously, realizing the dynamic adjustment of the distance between the arc-shaped hot head 4 and the knitting tape. During this process, multiple sets of guide rods 14 pass through the lead screw moving block 13, providing stable sliding guidance and preventing the lead screw moving block 13 from shifting or shaking during movement, ensuring the accuracy of the arc-shaped hot head 4 position adjustment. In addition, the support slide rods 15 on both sides of the motion base block 8 slide in cooperation with the support sliders 16 on the inner wall of the device housing 1, further enhancing the stability and rigidity of the arc-shaped hot head 4 during movement. During the position adjustment of the arc-shaped hot head 4, the high-precision positioning component 5 monitors its depth in real time. The brush head 18 is fixed to the support slide rod 15 and moves synchronously with the arc-shaped hot head 4, sliding between the first electrode plate 19 and the second electrode plate 20. The conductive material coating on the first electrode plate 19 and the detection circuit assembly 21 causes the brush head 18 to change its conductive length relative to the first electrode plate 19 as it slides, thereby changing the loop resistance value. The amplification circuit and resistance detection circuit in the detection circuit assembly 21 collect and analyze this resistance value change in real time. Based on the pre-established resistance value-position relationship model, the detection circuit assembly 21 can convert the resistance value into precise position data of the brush head 18, and then provide feedback on the current position of the arc-shaped hot head 4. The control system compares this position data with preset process parameters. If there is a deviation, it immediately sends an adjustment command to the servo motor 12, forming a closed-loop control of "detection-feedback-adjustment". For example, when processing thinner cotton knitted tapes, the system presets a smaller heat head spacing, and the high-precision positioning component 5 monitors the position of the arc-shaped heat head 4 in real time to ensure that it maintains a safe and effective processing distance from the knitted tape, avoiding overburning; while when processing thicker polyester blended knitted tapes, the system automatically increases the heat head spacing and ensures thorough singeing through real-time detection, effectively preventing incomplete singeing due to improper distance.After being singed by the arc-shaped hot head 4, the knitted tape is discharged through the outlet, completing the removal of surface lint and anti-pilling processing. Throughout the process, the device achieves adaptive processing of knitted tapes of different models and materials through the linkage of the adjustable depth component 3 and the high-precision positioning component 5, ensuring the stability and consistency of the singeing process and significantly improving the anti-pilling performance and processing quality of the knitted tape.
