Technical Field

[0001] The utility model relates to the technical field of cotton yarn winding and twisting processing, and more specifically, it relates to a yarn winding and twisting device. Background Art

[0002] Cotton yarn is yarn made from cotton fiber through the spinning process. After the plying process, it is called cotton thread. According to different spinning processes, it can be divided into carded yarn and combed yarn. No matter what kind of yarn is rolled, the plying into thread requires corresponding twisting operations. The cotton yarn twisting machine is a textile equipment that twists multiple yarns together to form cotton yarn.

[0003] During the use of the twisting device, dust and impurities will adhere to the surface of the yarn after it is twisted. However, most of the existing twisting devices do not have the function of cleaning the dust and impurities on the surface of the yarn. As a result, the dust and impurities attached to the surface of the yarn cannot be cleaned in time after twisting, thereby affecting the quality of the yarn. Summary of the invention

DETAILED DESCRIPTION

[0021] See also Figure 1-5 , the utility model provides the following technical solutions:

[0022] Specifically, it refers to a yarn twisting device, including a base plate 1, on which a winding assembly 2, a reeling assembly 3 and a wire harness shell 4 are respectively provided. The wire harness shell 4 is located between the winding assembly 2 and the reeling assembly 3, and the three are on the same horizontal line. The winding assembly 2 and the reeling assembly 3 are both existing patents: The disclosed technology in CN220665548U is not repeated here. Wire harness holes 6 are opened on the left and right sides of the wire harness shell 4, and the yarn passes through the wire harness shell 4 through the wire harness hole 6. The wire harness shell 4 is provided with a dust suction mechanism 5 for absorbing dust inside the wire harness shell 4.

[0023] The dust suction mechanism 5 includes a dust suction hopper 501, which is arranged in the wiring harness shell 4 and is connected to the inside of the wiring harness shell 4. A dust collecting shell 503 is arranged on the outer surface of the wiring harness shell 4, and a dust suction pipe 502 is arranged between the upper surface of the dust collecting shell 503 and the dust suction hopper 501, so that dust enters the dust collecting shell 503 through the dust suction pipe 502. The outer surface of the dust collecting shell 503 is provided with a dust suction fan 504, and the air suction port of the dust suction fan 504 penetrates into the dust collecting shell 503, and a filter screen is arranged in the air suction port to block the discharge of dust. When in use, the dust suction fan 504 is operated, and the dust suction fan 504 draws air in the dust collecting shell 503 so that the dust collecting shell 503 is in a negative pressure state. At this time, the dust in the wiring harness shell 4 enters the dust collecting shell 503 along the dust suction pipe 502 under the action of atmospheric pressure, thereby achieving the purpose of dust collection.

[0024] A drawer 505 is provided on the front of the dust collecting shell 503, and the rear side of the drawer 505 slides into the dust collecting shell 503 and slides on the bottom wall of the dust collecting shell 503. At the same time, a sealing rubber pad is provided on the outer surface of the drawer 505 that contacts the inner wall of the dust collecting shell 503 to increase the sealing performance, thereby preventing external air from entering the dust collecting shell 503 through the gap between the drawer 505 and the dust collecting shell 503, thereby reducing the effect of extracting dust from the wiring harness shell 4.

[0025] A gear ring 7 is provided in the wiring harness housing 4, and the gear ring 7 and the wiring harness hole 6 are on the same axial line. A gear 8 is meshed and connected on the upper side of the gear ring 7. A servo motor 9 for driving the gear 8 to rotate is provided on the right side surface of the wiring harness housing 4. A plurality of built-in brushes 10 for cleaning the surface of the yarn are provided on the inner side surface of the gear ring 7. A lateral brushing mechanism 11 for lateral cleaning of the yarn is provided in the wiring harness housing 4. When in use, the gear 8 is driven to rotate by the servo motor 9, so that the gear ring 7 rotates under the meshing transmission of the gear 8, and the built-in brush 10 rotates synchronously with the gear ring 7. When the yarn is conveyed through the wiring harness hole 6, the rotating built-in brush 10 can brush the surface of the yarn, so that dust or fluff attached to the surface of the yarn falls off under the brushing of the built-in brush 10, and the problem of not being able to clean the dust on the surface of the yarn will not occur, thereby ensuring the quality of the yarn in later use.

[0026] An annular groove 12 is provided on the inner wall of the wiring harness housing 4 near the gear ring 7. The transverse section of the annular groove 12 is circular. An annular slider 13 adapted to the annular groove 12 is provided on the side surface of the gear ring 7 near the annular groove 12. The annular slider 13 slides in the annular groove 12. Therefore, when the gear ring 7 rotates, the annular slider 13 slides synchronously in the annular groove 12. At the same time, since the transverse section of the annular groove 12 is circular, the annular groove 12 will have a restrictive effect on the annular slider 13, so the gear ring 7 will not have the problem of tipping over.

[0027] The transverse brushing mechanism 11 includes a mounting plate 111, which is arranged on the front inner wall of the wiring harness housing 4. A transverse slide rod 112 is slidably sleeved on the mounting plate 111. A movable ring 113 is fixedly installed on one end of the transverse slide rod 112. The inner ring of the movable ring 113 is also on the same axial line as the wiring harness hole 6. The inner ring of the movable ring 113 is provided with an annular brush 114 that slides on the surface of the yarn. Therefore, by controlling the transverse slide rod 112 to move back and forth on the mounting plate 111, the movable ring 113 drives the annular brush 114 to brush back and forth on the surface of the yarn, which can further improve the cleaning effect of the surface of the yarn after twisting, and try to avoid the problem of more dust adhering to the surface of the yarn affecting the later use effect.

[0028] The outer surface of the transverse slide bar 112 is sleeved with a limiting ring 115, and a spring 116 that is movably sleeved on the outer surface of the transverse slide bar 112 is provided between the limiting ring 115 and the mounting plate 111. An arc-shaped protrusion 117 is provided on the surface of the gear ring 7 facing the transverse slide bar 112. The end of the transverse slide bar 112 away from the movable ring 113 is hemispherical and contacts the arc surface of the arc-shaped protrusion 117. In this way, when the gear ring 7 rotates, the arc-shaped protrusion 117 rotates synchronously with the gear ring 7. When the arc-shaped protrusion 117 is in contact with the gear ring 7, the arc-shaped protrusion 117 rotates synchronously with the gear ring 7. When the transverse slide bar 112 contacts the arc-shaped protrusion 117, the arc-shaped protrusion 117 will form a thrust on the transverse slide bar 112, causing the transverse slide bar 112 to slide on the support plate 111. At the same time, the spring 116 is squeezed and contracted by the limiting ring 115. When the transverse slide bar 112 does not contact the arc-shaped protrusion 117, the transverse slide bar 112 is pushed by the spring 116 to move in the direction. The above structure is adopted to achieve the purpose of controlling the back and forth displacement of the transverse slide bar 112, thereby ensuring the cleaning effect of the annular brush 114 on the yarn.

[0029] The working principle of the yarn twisting device provided by the utility model is as follows: the gear 8 is driven to rotate by the servo motor 9, so that the gear ring 7 rotates under the meshing transmission of the gear 8, and the built-in brush 10 rotates synchronously with the gear ring 7. When the yarn is transported through the bundle hole 6, the rotating built-in brush 10 can brush the surface of the yarn, so that dust or lint attached to the surface of the yarn falls off under the brushing of the built-in brush 10.
