Specific embodiments

[0020] Please refer to Figures 1-6 , the present utility model provides a technical solution: a yarn feeding device for a textile machine, including a box body 1, several support columns 2 are fixedly connected to the bottom of the box body 1, the bottom of the support columns 2 is fixedly connected to a bottom plate 3, an air extraction pump 7 is fixedly installed on the top of the bottom plate 3, a dust collection box 4 is communicated with the bottom of the box body 1, a cover plate 8 is hinged to the top of the box body 1, a dust-proof cover 5 is fixedly connected to the front side of the box body 1, an air delivery cover 9 is fixedly connected to the rear side of the box body 1, an air extraction port of the air extraction pump 7 is fixedly communicated with an air extraction pipe 11, the top of the air extraction pipe 11 is fixedly communicated with the bottom of the dust collection box 4, an air outlet of the air extraction pump 7 is fixedly communicated with an air outlet pipe 10, the top of the air outlet pipe 10 is fixedly communicated with the bottom of the air delivery cover 9, a detection component for detecting yarn breakage is installed on the box body 1, a cleaning component for cleaning impurities such as fluff and dust on the surface of the yarn is installed on the box body 1, and a driving component for driving the cleaning component to move is installed on the dust-proof cover 5.

[0021] When this yarn feeding device is in use, the yarn passes through the detection component, the box body 1, and the cleaning component from left to right in sequence, and finally passes out from the right side of the box body 1 and is conveyed to the spinning machine. The detection component is used to detect whether the yarn is broken. If the yarn is broken, a signal will be immediately transmitted to the console to control the yarn feeding device and the textile machine to stop, avoiding the expansion of losses. Under the action of the driving component, the cleaning component can remove impurities such as fluff and dust on the yarn, avoiding affecting the product quality. At the same time, under the suction of the air extraction pump 7, the impurities are concentrated in the dust collection box 4. The cover plate 8 on the top of the box body 1 can prevent the impurities from diffusing into the air, ensuring the physical health of the workers.

[0022] The cleaning component includes two groups of air pipes 12. The front end of the air pipe 12 is fixedly connected to the inner wall of the box body 1, the rear end of the air pipe 12 is fixedly communicated with the air delivery cover 9, and a number of cleaning nozzles 13 are communicated on the air pipe 12. Four groups of support rods 14 are arranged in the box body 1. The rear end of the support rod 14 is slidably connected to the inner wall of the box body 1. The front end of the support rod 14 is fixedly connected with a connecting block 19. A slider is arranged on the connecting block 19. A chute matching the slider is arranged on the box body 1. The slider is slidably connected with the chute. A number of connecting rods 17 are fixedly connected in the up and down opposite directions of the support rod 14. The other end of the connecting rod 17 is fixedly connected with a cleaning block 18.

[0023] After the yarn enters the box body 1, it first passes between the two groups of cleaning blocks 18 to remove impurities such as fluff and dust attached to the surface, and then passes through the cleaning nozzles 13. The air output by the air extraction pump 7 passes through the air outlet pipe 10, the air delivery cover 9, and the air pipe 12 in sequence and is blown out from the cleaning nozzles 13, which can blow off the residual impurities on the yarn. Then it passes between the two groups of cleaning blocks 18 to ensure that the impurities on the yarn are removed completely. Finally, it passes out of the box body 1 and is conveyed to the textile machine.

[0024] The driving component includes a motor 6. An installation plate 16 is fixedly connected to the front side of the dust-proof cover 5. The motor 6 is fixedly installed on the top of the installation plate 16. The output end of the motor 6 is fixedly connected with a gear 23. The front end of the connecting block 19 is hinged with a first connecting rod 20. The other ends of the upper and lower two groups of first connecting rods 20 are hinged with a moving block 21. The moving block 21 is slidably connected to the front side of the box body 1. Two groups of toothed plates 22 are arranged between the two groups of moving blocks 21. The left toothed plate 22 is fixedly connected to the upper end of the left moving block 21, and the right toothed plate 22 is fixedly connected to the lower end of the right moving block 21. The two groups of toothed plates 22 are meshed with the gear 23.

[0025] The motor 6 starts to drive the gear 23 to rotate. The rotation of the gear 23 drives the two moving blocks 21 to move under the action of the two sets of toothed plates 22, and then drives the connecting block 19 and the support rod 14 to move up and down through the first connecting rod 20. When the two moving blocks 21 move towards the middle, the distance between the upper and lower support rods 14 decreases until the two cleaning blocks 18 abut against each other, clamping the yarn in the middle to clean the yarn. When the two moving blocks 21 move towards the two sides, the distance between the upper and lower support rods 14 increases, and at this time, the yarn can be inserted.

[0026] The detection component includes several groups of pressure sensors 24. The pressure sensors 24 are fixedly connected to the left side of the box body 1. A second connecting rod 26 is arranged below the pressure sensor 24. The second connecting rod 26 is hinged to the box body 1. The other end of the second connecting rod 26 is rotatably connected to a yarn guide wheel 25. A support plate 27 is arranged below the second connecting rod 26. The support plate 27 is fixedly connected to the box body 1. A telescopic rod 29 is hinged to the top of the support plate 27. The other end of the telescopic rod 29 is hinged to the bottom of the second connecting rod 26. A spring 28 is sleeved outside the telescopic rod 29. The bottom of the spring 28 abuts against the top of the support plate 27, and the top of the spring 28 abuts against the bottom of the second connecting rod 26.

[0027] When the device is operating normally, the yarn passes through the box body 1 through the yarn guide wheel 25. The spring 28 is compressed by the pressure of the yarn, and the second connecting rod 26 moves away from the pressure sensor 24. If the yarn breaks, the spring 28 rebounds, driving the second connecting rod 26 to press on the pressure sensor 24. The pressure sensor 24 receives the pressure signal and transmits it to the console to control the shutdown.

[0028] A filter screen 15 is fixedly connected to the inner wall of the dust collection box 4.

[0029] Prevent impurities from entering the air pump 7 along with the air.

[0030] Cleaning sponges are bonded to the upper and lower opposite surfaces of the cleaning block 18.

[0031] Working principle: When this yarn feeding device is in use, the yarn first passes through the yarn guide wheel 25 and enters the box body 1. The spring 28 is compressed by the pressure of the yarn, and the second connecting rod 26 moves away from the pressure sensor 24. If the yarn breaks, the spring 28 rebounds, driving the second connecting rod 26 to press on the pressure sensor 24. The pressure sensor 24 receives the pressure signal and transmits it to the console to control the shutdown, avoiding the expansion of losses. The motor 6 starts to drive the gear 23 to rotate. The rotation of the gear 23 drives the two moving blocks 21 to move under the action of the two sets of toothed plates 22, and then drives the connecting block 19 and the support rod 14 to move up and down through the first connecting rod 20. When the two moving blocks 21 move towards the middle, the distance between the upper and lower support rods 14 decreases until the two cleaning blocks 18 abut against each other, clamping the yarn in the middle to clean the yarn. When the two moving blocks 21 move towards both sides, the distance between the upper and lower support rods 14 increases, and at this time, the yarn can be inserted. After the yarn enters the box body 1, it first passes between the two cleaning blocks 18 to remove impurities such as fluff and dust attached to the surface, and then passes through the cleaning nozzle 13. The air output by the air extraction pump 7 passes through the air outlet pipe 10, the air delivery hood 9, and the air delivery pipe 12 in sequence and is blown out from the cleaning nozzle 13, which can blow off the remaining impurities on the yarn. Then it passes between the two cleaning blocks 18 to ensure that the impurities on the yarn are completely removed, avoiding affecting the product quality. Finally, it passes out of the box body 1 and is transported to the textile machine. The impurities in the box body 1 are concentrated in the dust collection box 4 under the action of the air extraction of the air extraction pump 7. At the same time, under the cooperation of the cover plate 8 and the filter screen 15, the impurities are prevented from diffusing into the air, protecting the health of the workers.
