[0002] A knitted fabric is formed by feeding one or several groups of parallel yarns into all the working needles of the machine in the warp direction and forming loops at the same time. This method is called warp knitting, the fabric is called warp knitted fabric, and the machine that completes this warp knitting is called a warp knitting machine.

[0003] Warp knitting machines can produce a variety of knitwear, including T-shirts, sweaters, sweaters, skirts, trousers and shirts, which are popular among consumers because of their softness, comfort and breathability.

After the device is started, the motor 12 will start and cause the first roller 13 to rotate. After the first roller 13 rotates, the yarn will be unwound, and the yarn will pass through the fixing plate 14 during the movement. The yarn passes through the fixing plate When the top plate 14 comes into contact with the top plate 16 and squeezes the top plate 16, the top plate 16 will transfer the pressure to the spring 15 after being squeezed, so that the spring 15 is in a compressed state. When the spring 15 is compressed, it will bring the top plate 16 closer to the fixed plate 14. When the top plate 16 moves, it will also drive the elastic cloth 17 to move together, so that the elastic cloth 17 is in a bent state. Then the spring 15 will release the elastic potential energy and apply elastic force to the top plate 16. The top plate 16 will apply elastic force to the yarn so that the yarn receives additional support when it moves, thereby increasing the tension of the yarn when it moves, and reducing the friction caused by the contact between the yarn and other parts when it moves due to relaxation; after the top plate 16 comes into contact with the yarn, it will squeeze the yarn under the elastic force of the elastic cloth 17, thereby increasing the tension of the yarn when it moves, reducing the contact between the yarn and other parts when it moves, reducing the wear caused by friction when the yarn moves, and extending the service life of the yarn.

[0027] See also Figure 3 and Figure 4 As shown, a first fixed groove 2 is opened in the middle of the top plate 16; a second roller 22 is rotatably connected to the middle of the first fixed groove 2; a plurality of protrusions 23 are fixedly connected to the middle of the second roller 22; the adjacent protrusions 23 are symmetrically arranged; when the yarn contacts the top plate 16, it will also contact the second roller 22, and the second roller 22 will rotate under the friction between the yarn, so that the sliding friction between the yarn and the top plate 16 is converted into rolling friction, reducing the friction force when the yarn moves, and at the same time, before the yarn is unwound, the staff can adjust the yarn to between a pair of protrusions 23. If the yarn is impacted when moving, it will move to the surface of the protrusion 23, and then the yarn will slide along the surface of the protrusion 23 and slide between the pair of protrusions 23, reducing the amplitude of the yarn deviation; by setting the second roller 22, the second roller 22 will roll when rubbing against the yarn and reduce the friction force when the yarn moves, further reducing the wear of the yarn when moving, and improving the quality of the products produced by the device.

[0030] See also Figures 1 to 5 As shown, a plurality of rubber plates 5 are fixedly connected to the middle of the third roller 43; the rubber plates 5 are of an arc-shaped structure; when the third roller 43 rotates, the rubber plates 5 are driven to rotate together, and when the rubber plates 5 rotate, they contact and squeeze the yarn wound on the surface of the first roller 13, so that the yarn wound on the surface of the first roller 13 is more compact; by providing the rubber plates 5, when the rubber plates 5 rotate, the yarn on the surface of the first roller 13 is squeezed, the looseness of the yarn surface is reduced, and the compactness inside the yarn is enhanced.

[0032] See also Figure 2As shown, a baffle 7 is symmetrically fixed to the middle of the collecting box 63; the baffle 7 is an arc-shaped structure; when the bristles 44 clean the yarn wrapped around the surface of the first roller 13, the removed dust will diffuse and reach the surface of the baffle 7, and the baffle 7 will enhance the collection of impurities by the collecting box 63, further reducing the impurities remaining on the surface of the device.

[0033] Working principle: after the device is started, the motor 12 will start and make the first roller 13 rotate. After the first roller 13 rotates, the yarn will be unwound. During the movement, the yarn will pass through the fixed plate 14. When the yarn passes through the fixed plate 14, it will come into contact with the top plate 16 and squeeze the top plate 16. After the top plate 16 is squeezed, the pressure will be transmitted to the spring 15 so that the spring 15 is in a compressed state. When the spring 15 is compressed, it will bring the top plate 16 closer to the fixed plate 14. When the top plate 16 moves, it will also drive the elastic cloth 17 to move together so that the elastic cloth 17 is in a bent state. Then the spring 15 will release the elastic potential energy and apply elastic force to the top plate 16. The top plate 16 will apply elastic force to the yarn The force makes the yarn receive additional support when it moves, increases the tension of the yarn when it moves, and reduces the friction caused by the contact between the yarn and other parts due to relaxation when the yarn moves; when the yarn contacts the top plate 16, it will also contact the second roller 22. The second roller 22 will rotate under the friction between the yarn, so that the sliding friction between the yarn and the top plate 16 is converted into rolling friction, reducing the friction force on the yarn when it moves. At the same time, before the yarn is unwound, the staff can adjust the yarn to between a pair of protrusions 23. If the yarn is impacted when moving, it will move to the surface of the protrusion 23, and then the yarn will slide along the surface of the protrusion 23 and slide between the pair of protrusions 23. The yarn is then moved to the first roller 13 and the second roller 22 is moved to the second roller 13. The second roller 13 is moved to the first roller 13 and the second roller 13 is moved to the second roller 13. The second roller 13 is moved to the first roller 13 and the second roller 13 is moved to the second roller 13. The second roller 13 is moved to the second roller 13 and the second roller 13 is moved to the second roller 13. The second roller 13 is moved to the first roller 13 and the second roller 13 is moved to the second roller 13. The second roller 13 is moved to the second roller 13 and the second roller 13 is moved to the second roller 13. The second roller 13 is moved to the second roller 13 and the second roller 13 is moved to the second roller 13. The second roller 13 is moved to the second roller 13 and the second roller 13 is moved to the second roller 13. The second roller 13 is moved to the second roller 13 and the second roller 13 is moved to the second roller 13. When the third roller 43 rotates, the rubber plate 5 is driven to rotate together. When the rubber plate 5 rotates, it contacts and squeezes the yarn wound on the surface of the first roller 13, so that the yarn wound on the surface of the first roller 13 is more tightly wound. When the bristles 44 clean the yarn on the surface of the first roller 13, the removed dust will diffuse, and the diffused dust will reach the inside of the collecting box 63 and be collected by the collecting box 63, thereby reducing the dust remaining on the surface of the device. When the bristles 44 clean the yarn wound on the surface of the first roller 13, the removed dust will diffuse and reach the surface of the baffle 7, and the baffle 7 will enhance the collection of impurities by the collecting box 63, thereby further reducing the impurities remaining on the surface of the device.
