[0001] This utility model relates to the field of textile processing technology, specifically to a yarn feeding device for a small circular knitting machine. Background Technology
[0002] A circular knitting machine is a type of mechanical equipment used to produce small knitted items. It is widely used in the production of small-sized knitted products such as hats, scarves, and cuffs. Circular knitting machines typically have high-speed production capabilities, which can improve production efficiency. Some circular knitting machines are equipped with computer control systems, enabling them to realize complex patterns and designs.
[0003] However, some existing small circular knitting machines do not have a cleaning structure at the yarn inlet. As the yarn feeds, dust carried on the yarn moves along with it and rubs against the structure of the high-speed rotating small circular knitting machine, generating a lot of static electricity. This not only makes the small circular knitting machine prone to malfunction, but also makes the yarn prone to breakage and damage. Utility Model Content

As a result, the yarn carrying dust rubs against the structure of the high-speed rotating small circular knitting machine, generating a lot of static electricity. This not only easily causes the small circular knitting machine to malfunction, but also easily causes the yarn to break and be damaged.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a yarn feeding device for a small circular knitting machine, comprising a worktable and a support, wherein the worktable surface is fixedly connected to the support, the top of the support is fixedly connected to a support plate, a water tank is fixedly connected between adjacent support plates, a water-absorbing component is installed at the bottom of the water tank, a small circular knitting machine is fixedly connected to the middle of the worktable surface, and cleaning mechanisms are provided on both sides of the small circular knitting machine, and an adjustment mechanism is installed on the cleaning mechanism;
[0006] The cleaning mechanism includes a concave plate fixedly connected to the workbench surface. A cleaning cotton roller is disposed in the groove of the concave plate, and the outer wall of the roller shaft of the cleaning cotton roller is slidably connected to the inner wall of the groove of the concave plate. A first pipe is fixedly connected inside the concave plate. A second pipe and an atomizing nozzle are respectively connected to the upper and lower parts of the first pipe. The top end of the second pipe passes through the bracket and is connected to the water absorption component.
[0007] Preferably, the water-absorbing component includes a vertical plate fixed to the bottom of the water tank, a water pump fixed inside the vertical plate, the inlet and outlet of the water pump being connected to a third pipe and a fourth pipe respectively, the top end of the third pipe being connected to the water tank, and the bottom end of the fourth pipe being connected to the second pipe through a T-joint.
[0008] Preferably, the adjustment mechanism includes a horizontal plate fixed to the outer wall of the concave plate, an electric push rod fixed to the bottom end of the horizontal plate, and a connecting block fixed to the telescopic end of the electric push rod. The connecting block is hinged to the roller shaft of the cleaning cotton roller via a pin.

[0020] Please see Figures 1-5 A yarn feeding device for a small circular knitting machine includes a workbench 1 and a support 2. The support 2 is fixedly connected to the table surface of the workbench 1, and a support plate 3 is fixedly connected to the top of the support 2. A water tank 4 is fixedly connected between adjacent support plates 3. A water-absorbing component is installed at the bottom of the water tank 4. A small circular knitting machine 18 is fixedly connected to the middle of the table surface of the workbench 1, and a cleaning mechanism is provided on both sides of the small circular knitting machine 18. An adjustment mechanism is installed on the cleaning mechanism.
[0021] The cleaning mechanism includes a concave plate 5 fixedly connected to the workbench 1. A cleaning cotton roller 6 is arranged in the groove of the concave plate 5, and the outer wall of the roller shaft of the cleaning cotton roller 6 is slidably connected to the inner wall of the groove of the concave plate 5. A first pipe 13 is fixedly connected inside the concave plate 5. A second pipe 12 and an atomizing nozzle 14 are respectively connected to the upper and lower parts of the first pipe 13. The top end of the second pipe 12 passes through the bracket 2 and is connected to the water absorption component.
[0022] Therefore, there are two support plates 3, which are arranged opposite each other. Two inlets and two outlets are machined on the top of the workbench 1, and guide rollers are set inside to guide the yarn. Slide grooves are machined on the front and rear ends of the concave plate 5 to limit the roller shaft of the cleaning cotton roller 6. Several atomizing nozzles 14 are set and distributed at equal intervals to spray evenly. At the same time, a controller can be set on the right side of the bracket 2 to control the various electrical structures.
[0023] Specifically, the water in the water tank 4 can be drawn out by the water suction component and the water is finally sprayed out in the form of water mist from the atomizing nozzle 14. In conjunction with the cleaning cotton roller 6, the moving yarn is cleaned to remove the dust carried by the yarn, eliminate the static electricity generated, and keep the yarn clean.
[0024] The water suction device includes a vertical plate 7 fixedly connected to the bottom of the water tank 4. A water pump 8 is fixedly connected inside the vertical plate 7. The inlet and outlet of the water pump 8 are respectively connected to a third pipe 9 and a fourth pipe 10. The top end of the third pipe 9 is connected to the water tank 4, and the bottom end of the fourth pipe 10 is connected to the second pipe 12 through a three-way connector 11.
[0025] Specifically, the water pump 8 can be started to draw water out of the water tank 4 through the first pipe 13, and then drain the water into the second pipe 12 through the fourth pipe 10 and the three-way connector 11. The water then flows into the first pipe 13 through the second pipe 12 and finally sprays out in the form of water mist from the atomizing nozzle 14. This automated design makes operation simple and convenient.
[0026] The adjustment mechanism includes a horizontal plate 15 fixed to the outer wall of the concave plate 5. An electric push rod 16 is fixed to the bottom end of the horizontal plate 15, and a connecting block 17 is fixed to the telescopic end of the electric push rod 16. The connecting block 17 is hinged to the roller shaft of the cleaning cotton roller 6 through a pin.
[0027] Specifically, the electric actuator 16 can be activated to make two adjacent electric actuators 16 move synchronously. The electric actuator 16 drives the cleaning roller 6 to move through the connecting block 17 so that the surface of the cleaning roller 6 can better fit with the yarn. At the same time, the connecting block 17 can also be disassembled from the cleaning roller 6 through the pin to replace the cleaning roller 6.
[0028] The front end and side wall of the water tank 4 are respectively equipped with an observation window 21 and a fifth pipe 22;
[0029] Specifically, the fifth pipe 22 is connected to the external water supply structure to supply water to the inside of the water tank 4. The remaining water in the water tank 4 can be observed at any time through the observation window 21.
[0030] Both sides of the support 2 are provided with yarn frames 19, and yarn rollers 20 are configured on the yarn frames 19.
[0031] A pair of feed rollers 23 are rotatably connected to both sides of the bracket 2.
[0032] Specifically, when the yarn passes through the middle of a pair of feed rollers 23, the pair of feed rollers 23 can guide and limit the yarn.
[0033] It is worth noting that the electrical structure involved in this application can be selected according to the user's needs, and the corresponding circuit connection and control are all existing technologies that can be fully implemented by those skilled in the art, so they will not be described in detail here.
[0034] The working principle of this application is illustrated below with a preferred embodiment;
[0035] Several yarn rollers 20 can be installed on the yarn frame 19. The yarn is then removed from the yarn rollers 20 and passed sequentially through the opening end of the yarn frame 19, between a pair of infeed rollers 23, above the cleaning roller 6, the inlet and outlet of the worktable 1, and finally connected to the small circular knitting machine 18. Afterwards, the external power supply and control circuits of each electrical component are connected, and the electric push rods 16 are activated, causing two adjacent electric push rods 16 to move synchronously. The electric push rods 16 drive the cleaning roller 6 to move via the connecting block 17, allowing the surface of the cleaning roller 6 to better adhere to the yarn. Then, the small circular knitting machine 18 is started. The small circular knitting machine 18 feeds in yarn and knits simultaneously. At the same time, the water pump 8 is activated, causing the water pump 8 to draw water from the water tank 4 through the first pipe 13. The water is then discharged into the second pipe 12 through the fourth pipe 10 and the three-way connector 11. The water then flows into the first pipe 13 through the second pipe 12 and is finally sprayed out in a water mist from the atomizing nozzle 14. This, along with the cleaning cotton roller 6, cleans the moving yarn, removing dust carried by the yarn, eliminating static electricity, and keeping the yarn clean. This not only ensures the stable operation of the small circular knitting machine 18 but also reduces the likelihood of yarn breakage and damage, resulting in better performance.
