[0002] Traditional circular knitting machines are widely used in the textile industry, including apparel, home textiles, and industrial textiles, and are the core equipment for realizing the knitting and forming of yarn. They weave various yarns into knitted fabrics through a loop-forming system, and are compatible with a variety of raw materials such as cotton, linen, and synthetic fibers. With the advantage of efficient and continuous production, they provide downstream industries with batch fabric substrates. At the same time, through basic tension adjustment and guiding structures, they ensure the orderly conduct of knitting operations, making them an indispensable key piece of equipment for large-scale production in the textile industry.

Detailed Implementation

[0027] The present invention will be further described in detail below with reference to embodiments:

[0028] Example 1, as Figures 1-8 As shown, the present invention provides a circular knitting machine for uniform fabric weaving, comprising: a knitting mechanism, the knitting mechanism including a mounting frame 11, a loop-forming system 12 for weaving yarns into loops fixedly connected to the top of the mounting frame 11, and a control panel 13 fixedly connected to the surface of the mounting frame 11; a pretreatment mechanism, the pretreatment mechanism including a guiding component and a drying component, the guiding component being fixedly mounted on the top of the mounting frame 11, and the drying component being fixedly mounted on the surface of the guiding component; and a tension adaptive component, the tension adaptive component including a mounting ring 31 and a monofilament adjustment unit, the monofilament adjustment units being evenly distributed in a circumferential shape on the surface of the mounting ring 31, and the mounting ring 31 being fixedly mounted on the surface of the guiding component.

[0029] It should be noted that the core framework of "knitting + pretreatment + tension adjustment" is constructed, with the three components connected sequentially along the yarn conveying path. The fixed design of the mounting ring 31 and the guide component ensures that the monofilament adjustment unit and the pretreatment component are precisely aligned, providing a continuous operation link of "pretreatment first, tension adjustment then knitting" for each yarn. The control panel 13 provides the basis for parameter adjustment for the coordinated operation of each mechanism.

[0030] In this embodiment, the pretreatment mechanism can improve the yarn condition in advance, and the tension adaptive component can adjust the tension of the monofilaments in a targeted manner. The two work together to provide a stable yarn raw material for the loop forming system 12, which structurally avoids weaving defects caused by moisture, impurities and uneven tension, laying the foundation for high-precision fabric weaving.

[0031] Example 2, as Figures 1-8As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the guiding component includes a support frame 21, which is fixedly installed on the top of the mounting frame 11. A fixing ring 22 is fixedly connected to the top of the support frame 21. A first mounting member 23 is inserted into the surface of the fixing ring 22. A fixing screw is threaded onto the surface of the first mounting member 23, and one end of the fixing screw is tightly abutted against the surface of the fixing ring 22. A first guide wheel 24 is rotatably connected to one side of the first mounting member 23. The drying component includes a fixing rod 25, the upper end of which is fixedly connected to the bottom of the first mounting member 23. A vortex guide tube 26 is fixedly connected to the lower end of the fixing rod 25. An air inlet branch pipe 27 is provided on one side of the upper end of the vortex guide tube 26, and an outlet branch pipe 28 is provided on one side of the lower end of the vortex guide tube 26. One end of the conduit 26 is connected to the air outlet pipe 29. The drying component and the guide component are evenly distributed in multiple sets around the fixed ring 22, and the number corresponds to the single filament adjustment unit. The pretreatment mechanism also includes an air supply component, which includes an air supply ring pipe 210 and an air outlet ring pipe 211. The interior of the air supply ring pipe 210 is connected to the upper end of multiple sets of circumferentially distributed air inlet branch pipes 27. The interior of the air outlet ring pipe 211 is connected to the lower end of multiple sets of circumferentially distributed vortex guide pipes 26. The interior of the air supply ring pipe 210 is connected to an air pump 212 with built-in electromagnetic heating function through a pipe. The interior of the air outlet ring pipe 211 is connected to a filter component through a pipe. The filter component includes a filter box 213 with an air outlet on one side of the bottom of the inner cavity. A filter cover 214 is inserted into the interior of the filter box 213. A door 215 is provided on the front of the filter box 213.

[0032] It should be noted that the design of the vortex guide tube 26 can extend the contact time between the yarn and the hot airflow, improve the drying and impurity removal effect, and the multiple sets of components correspond one-to-one with the monofilament adjustment unit to ensure that each yarn completes pretreatment independently and avoids cross-contamination; the filter component and the air supply component form a closed-loop airflow circuit, which saves energy and prevents impurities from sticking back to the yarn.

[0033] In this embodiment, by optimizing the specific structure of the pretreatment mechanism, the pain point of traditional devices lacking targeted pretreatment is solved: the heated gas generated by the air pump 212 is sent into the vortex guide pipe 26 through the air supply ring pipe 210 and the air inlet branch pipe 27 to uniformly dry the yarn and blow away surface impurities. The exhaust gas enters the filter box 213 through the air outlet ring pipe 211 and is discharged after being filtered by the filter cover 214. The position of the first mounting part 23 can be adjusted by the fixing screw, and the first guide wheel 24 precisely guides the yarn path to ensure that the pretreated yarn smoothly enters the tension adjustment stage.

[0034] Example 3, as Figures 1-8As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the single-filament adjustment unit includes a second mounting member 32, the inner wall of the second mounting member 32 overlaps with the surface of the mounting ring 31, the inner thread of the second mounting member 32 is connected to a fixing knob 33, the lower end of the fixing knob 33 is tightly abutted against the surface of the mounting ring 31, the inner cavity of the second mounting member 32 is provided with an insertion groove 34, one end of the inner cavity of the insertion groove 34 is fixedly connected to a spring 36, one end of the spring 36 is fixedly connected to a limit slider 35, the surface of the limit slider 35 is slidably connected to the inner wall of the insertion groove 34, the end of the limit slider 35 away from the spring 36 is fixedly connected to an insertion rod 37, one end of the insertion rod 37 is fixedly connected to a guide frame 38, and the surface of the guide frame 38 is rotatably connected to a second guide wheel 39.

[0035] It should be noted that the monofilament adjustment unit adopts an elastic adaptive structure. The elastic force of the spring 36 can be finely adjusted in real time according to the change of yarn tension. The cooperation between the limit slider 35 and the insertion slot 34 ensures a smooth adjustment process and avoids sudden tension changes. Furthermore, the position of the second mounting part 32 can be adjusted by the fixed knob 33 to adapt to the tension requirements of different specifications of yarn.

[0036] In this embodiment, after the yarn is pre-treated, it passes around the second guide wheel 39. When the yarn tension is too high, it will push the guide frame 38 to drive the insertion rod 37 and the limiting slider 35 to compress the spring 36 and buffer the tension impact. When the tension is too low, the spring 36 resets and pushes the slider to move, tightening the yarn and achieving dynamic tension balance. Multiple independent units work synchronously to ensure that the tension of each yarn is uniform, providing a guarantee for the precise weaving of the loop forming system 12.

[0037] The working principle of a circular knitting machine that produces evenly woven fabric will be explained in detail below.

[0038] like Figures 1-8As shown, the heating temperature, airflow intensity, and weaving parameters of the coiling system 12 of the air pump 212 are set via the control panel 13 on the surface of the mounting bracket 11. According to the yarn specifications, the position of the second mounting piece 32 on the mounting ring 31 is adjusted by the fixing knob 33 to complete the preparation before starting the equipment. Yarn pretreatment operation: The air pump 212 is started, and its built-in electromagnetic heating function heats the gas to the preset temperature. The hot airflow is distributed through the air supply ring pipe 210 to each group of air inlet branch pipes 27 and enters the vortex guide pipe 26. After being guided by the first guide wheel 24, the yarn passes through the vortex guide pipe 26 and comes into full contact with the hot airflow in the vortex path. The moisture is dried and the surface impurities are blown away. The exhaust gas is collected in the air outlet ring pipe 211 through the air outlet pipe 29 and sent into the filter box 213. After being filtered by the filter cover 214, it is discharged, realizing the integrated treatment of cleaning and drying. The pre-treated yarn passes through the outlet branch pipe 28, around the second guide wheel 39, and enters the tension adjustment stage. The spring 36, in conjunction with the limit slider 35, adaptively adjusts the yarn tension in real time—when the tension is too high, the spring 36 compresses to buffer; when the tension is too low, the spring 36 resets and tightens, ensuring that the tension of each yarn remains stable within the preset range, avoiding weaving defects caused by uneven tension. Multiple yarns with stable tension simultaneously enter the loop-forming system 12. The loop-forming system 12 completes the yarn weaving according to the preset parameters on the control panel 13. During the weaving process, the control panel 13 monitors the operating status of each mechanism in real time and can fine-tune the pre-treatment temperature, tension threshold, and weaving parameters according to the fabric forming effect, ensuring uniform fabric density and regular texture.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
