Description

Technical Field

[0001] This utility model relates to the field of circular knitting machines, and in particular to a circular knitting machine that can be adapted to different yarns. Background Technology

[0002] The circular knitting machine is a weft knitting device widely used in the textile industry. It mainly completes the continuous weaving of large-area fabrics through a circular needle mechanism. It features fast weaving speed, large fabric width, and adaptability to a wide range of products, and is widely used in clothing, home textiles, functional fabrics and other fields.

[0003] As shown in the reference case "A Circular Knitting Machine" (Announcement No. CN110983604B), when changing different yarns, it is necessary to unscrew the bolts inside the inner baffle, adjust the inner baffle, and then unscrew the bolts of the outer baffle to adjust the outer baffle. The opening and closing of the outer and inner baffles controls the quality of the fabric forming, so the adjustment is quite precise. The above method of adjustment is cumbersome, requires repeated data measurement, and wastes production time. This solution uses a connecting mechanism to adjust the positions of the inner and outer baffles synchronously, which is simpler and saves time.

[0004] Traditional circular knitting machines mostly use a fixed-size guide ring to guide the yarn into the needle area. The inner diameter of the guide ring is fixed and cannot be automatically or quickly adjusted according to the thickness of the yarn. When changing to different types of yarn, it is often necessary to change to a different model of guide ring. Utility Model Content

[0005] Based on this, it is necessary to address the issue that traditional circular knitting machines mostly use fixed-size guide rings to guide the yarn into the needle area. The inner diameter of these guide rings is fixed and cannot be automatically or quickly adjusted according to the yarn thickness. When changing to different types of yarn, different models of guide rings often need to be replaced. Therefore, a circular knitting machine adaptable to different yarn sizes should be provided, comprising: a fixed base, on the top of which the circular knitting machine is fixedly mounted, and multiple yarn guide nozzles rotatably mounted on the top of the circular knitting machine; and an adjustment and positioning mechanism, located on one side of the circular knitting machine, for adjusting and adapting to different yarn sizes. The adjustment and positioning mechanism includes a rotating needle bed, on the surface of which an adaptation component is provided, and on the other side of which an angle component is provided.

[0006] The adapter assembly includes multiple electric push rods fixedly installed on the top of the rotating needle bed. Each of the multiple electric push rods has an inlet wheel rotatably mounted on its top, and each of the multiple inlet wheels has an inlet ring on one side.

[0007] A limiting frame is fixedly installed on the surface of the inlet ring, the limiting frame extends into the inside of the inlet ring, and an airbag is fixedly installed inside the limiting frame. Both the limiting frame and the airbag are circular in shape.

[0008] A miniature air pump is fixedly installed on the outside of the limiting frame, and the output end of the miniature air pump is fixedly connected to the airbag.

[0009] A support rod is provided on one side of the guide wheel, and a movable groove is formed on the surface of the support rod. The guide ring is slidably connected to the movable groove.

[0010] A first screw is rotatably mounted on one side of the limiting frame, and a clamping plate is threadedly connected to the outer side of the first screw. One side of the clamping plate is slidably connected to one side of the limiting frame.

[0011] The angle assembly includes a rotating block rotatably mounted on one side of the guide wheel, a second screw rotatably mounted on one side of the rotating block, a limit block threadedly connected to the outer side of the second screw, and a plurality of insertion holes formed on the surface of the rotating block, with one side of the limit block adjacent to the insertion holes.

[0012] Two telescopic rods are slidably mounted on one side of the second screw, and the other ends of the two telescopic rods are fixedly connected to the limiting block. Beneficial effects

[0013] The above-mentioned circular knitting machines are compatible with different yarns.

[0014] 1. During use, the opening size of the inlet channel can be quickly adjusted through the adapter component to match yarns of different diameters, effectively improving the equipment's compatibility with various materials such as thick and thin yarns and elastic yarns; the angle component is used to precisely control the angle of the yarn guide path to ensure that the yarn enters the knitting area in the best posture, reducing yarn wrapping, skipped stitches and yarn breakage, and improving the stability and uniformity of the fabric loops.

[0015] 2. When it is necessary to adjust the yarn guide angle of the guide ring, the second screw can be rotated to make the limit block move axially and disengage from the current insertion hole position. At this time, the rotating block can rotate freely around the side axis of the guide wheel, thereby causing the support rod and the guide ring to deflect at an angle. Attached Figure Description

[0028] The following is combined Figures 1-4 The present invention describes a circular knitting machine adaptable to different yarns, comprising: a fixed base 100, on the top of which a circular knitting machine 200 is fixedly mounted, and multiple yarn guides 110 are rotatably mounted on the top of the circular knitting machine 200; an adjustment and positioning mechanism 300, which is used to adjust and adapt to yarns of different sizes and is disposed on one side of the circular knitting machine 200; wherein, the adjustment and positioning mechanism 300 includes a rotating needle bed 310, on the surface of which an adaptation component 320 is disposed, and on the other side of the adaptation component 320 an angle component 330 is disposed.

[0029] In this embodiment, the opening size of the inlet channel can be quickly adjusted by the adapter component 320 during use to match yarns of different diameters, effectively improving the compatibility of the equipment with various materials such as thick and thin yarns and elastic yarns; the angle component 330 is used to precisely control the angle of the yarn guide path to ensure that the yarn enters the knitting area in the best posture, reducing yarn wrapping, skipped stitches and yarn breakage problems, and improving the stability and uniformity of the fabric loops.

[0030] It should be noted that the existing circular knitting machine 200 typically includes basic components such as a frame, cylinder, needle bed, rotary drive mechanism, yarn feeder, tensioning mechanism, and fabric feeding device. The adapter component 320 and angle component 330 are installed on the top of the circular knitting machine 200 and are functionally linked with the yarn guide nozzle 110. Their adjustment structure is independent of the main drive system and cylinder mechanism, does not participate in the spindle operation and needle movement, and will not interfere with the cylinder rotation or needle circulation. In addition, the two components do not change the original installation position and working rhythm of the yarn guide nozzle 110 during the adjustment process, so they will not disrupt the continuity of the yarn feeding rhythm, nor will they have an adverse effect on the fabric forming rhythm. Thus, while achieving multi-filament adaptation capability, the integrity of the original structure and the stability of operation of the circular knitting machine 200 are fully guaranteed.

[0031] like Figure 2 , Figure 3 and Figure 4 As shown, the adapter component 320 includes multiple electric push rods 321 fixedly installed on the top of the rotating needle bed 310. Each of the multiple electric push rods 321 has an inlet wheel 322 rotatably mounted on its top, and each of the multiple inlet wheels 322 has an inlet ring 323 on one side.

[0032] In this embodiment, multiple electric push rods 321 synchronously drive the guide wheel 322 and the guide ring 323 to rise and fall in the vertical direction, thereby achieving precise adjustment of the height of the yarn guide path. The guide ring 323 is provided on one side of the guide wheel 322, and the guide ring 323 is used to limit the guiding position of the yarn before it enters the knitting area.

[0033] A limiting frame 324 is fixedly installed on the surface of the inlet ring 323. The limiting frame 324 extends into the inside of the inlet ring 323. An airbag 325 is fixedly installed inside the limiting frame 324. Both the limiting frame 324 and the airbag 325 are circular in shape.

[0034] In this embodiment, when it is necessary to adapt to threads of different thicknesses, the expansion degree of the airbag 325 can be adjusted by filling or releasing gas into the airbag 325, thereby changing the effective inner diameter of the inner ring of the limiting frame 324, and thus adjusting the thread passage space size of the guide ring 323. Specifically, when introducing a thin thread, the airbag 325 is inflated and expanded, reducing the effective diameter of the guide area to provide tighter guiding control and prevent the thin thread from shaking or drifting; when introducing a thick thread, the gas is released to cause the airbag 325 to contract, expanding the inner ring diameter to avoid the thread getting stuck or excessive friction.

[0035] A miniature air pump 326 is fixedly installed on the outside of the limiting frame 324, and the output end of the miniature air pump 326 is fixedly connected to the airbag 325.

[0036] In this embodiment, the miniature air pump 326 is used to inflate the airbag 325. By controlling the start and stop of the miniature air pump 326 and the air supply, the inflation and deflation operations of the airbag 325 can be realized, thereby precisely adjusting the through space inside the guide ring 323.

[0037] A support rod 327 is provided on one side of the guide wheel 322. A movable groove 328 is provided on the surface of the support rod 327. The guide ring 323 is slidably connected to the movable groove 328.

[0038] In this embodiment, the guide ring 323 slides along the direction of the support rod 327 to adjust the relative distance between the guide ring 323 and the guide wheel 322. This structure makes the position of the guide ring 323 no longer fixed, and can be finely adjusted according to the requirements of the thread tension, the optimization of the guide angle and the inner diameter position after the adjustment of the air bag 325, thereby further optimizing the guide path and wrap angle relationship of the thread before entering the needle area.

[0039] A first screw 329 is rotatably mounted on one side of the limiting frame 324. A clamping plate 3210 is threadedly connected to the outer side of the first screw 329. One side of the clamping plate 3210 is slidably connected to one side of the limiting frame 324.

[0040] In this embodiment, during use, by rotating the first screw 329, the clamping plate 3210 is moved axially to achieve contact or abutment with the surface of the support rod 327, thereby effectively limiting the position of the guide ring 323.

[0041] like Figure 2 , Figure 3 and Figure 4 As shown, the angle assembly 330 includes a rotating block 331 rotatably mounted on one side of the guide wheel 322. A second screw 332 is rotatably mounted on one side of the rotating block 331. A limit block 333 is threadedly connected to the outer side of the second screw 332. A plurality of insertion holes 334 are opened on the surface of the rotating block 331. One side of the limit block 333 is connected to the adjacent insertion hole 334.

[0042] In this embodiment, when it is necessary to adjust the yarn guiding angle of the guide ring 323, the second screw 332 can be rotated to move the limiting block 333 axially and disengage it from the current insertion hole 334 position. At this time, the rotating block 331 can rotate freely around the side axis of the guide wheel 322, thereby causing the support rod 327 and the guide ring 323 to deflect at an angle. After the adjustment is completed, the limiting block 333 is pressed back into the selected insertion hole 334 by rotating the second screw 332 to achieve a new angle positioning and locking.

[0043] Two telescopic rods 335 are slidably installed on one side of the second screw 332, and the other ends of the two telescopic rods 335 are fixedly connected to the limit block 333.

[0044] In this embodiment, the telescopic rod 335 can rotate and slide on one side of the second screw 332, and can guide the movement of the limiting block 333 when the second screw 332 rotates, so as to prevent the limiting block 333 from rotating synchronously with the second screw 332.

[0045] Working principle: The extension and retraction stroke of the electric push rod 321 can be adjusted via the control system according to the specifications of the selected yarn, changing the vertical height of the guide ring 323 to match the yarn guiding angle of the needle area. Subsequently, the micro air pump 326 inflates and deflates the air bag 325 as needed, automatically adapting the internal conduction diameter of the guide ring 323 to the yarn thickness, achieving self-adjusting closure or widening of the yarn guide channel. For further precise guidance, the operator can also slide the guide ring 323 along the support rod 327 to maintain a reasonable distance between it and the guide wheel 322, optimizing the yarn wrapping path. Adjustment complete. Afterwards, the clamping plate 3210 can be axially pressed by the first screw 329 to play a limiting and fixing role. In terms of angle adjustment, the rotating block 331 can rotate around the side axis of the guide wheel 322, causing the guide ring 323 to tilt as a whole, which helps to achieve a yarn entry angle that is more suitable for the current yarn tension characteristics. To ensure that the adjustment angle is accurate and controllable, the limiting block 333 can be disengaged and re-inserted into the insertion hole 334 at different angle positions under the guidance of the telescopic rod 335 to complete the angle locking. The whole process completes the multi-dimensional adjustment of the yarn guide height, width and angle without affecting the operation of the needle cylinder and the operation of the yarn guide nozzle 110.

[0046] It should be noted that the electric actuator and miniature air pump mentioned above are all components with relatively mature existing technologies. The specific models can be selected according to actual needs. At the same time, the electric actuator and miniature air pump can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
