Technical Field
[0001] This utility model relates to the field of spinning machine technology, and in particular to a yarn storage device for the splice of a rotor spinning machine. Background Technology
[0002] Rotor spinning machines are a new type of spinning equipment. They generate centrifugal force through high-speed rotating rotors to cohede and twist fibers into yarn. Compared with traditional ring spinning machines, they have unique advantages and application scenarios. The splicing and yarn storage device on the spinning machine is used to store excess yarn during the splicing process or to provide the yarn required for splicing. It can ensure stable yarn tension and improve splicing quality and efficiency.
[0003] During operation, when yarn winds around the outer surface of the yarn bobbin, a large amount of waste yarn accumulates on the surface. If this waste yarn remains on the outer surface of the bobbin for a long time, it may adversely affect the storage of subsequent yarn. In addition, if the waste yarn is not cleaned in time, it will be difficult to remove once it becomes entangled, thus affecting the normal operation of the yarn storage device. Utility Model Content
[0004] The purpose of this invention is to solve the problem that during the operation of a yarn storage device, a large amount of waste yarn accumulates on the outer surface of the yarn bobbin. If this waste yarn remains on the outer surface of the yarn bobbin for a long time, it may adversely affect the storage of subsequent yarn. In addition, if the waste yarn is not cleaned in time, it will be difficult to remove once it becomes entangled, thus affecting the normal operation of the yarn storage device. Therefore, this invention provides a yarn storage device for the splice of a rotor spinning machine.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a yarn storage device for a rotor spinning machine splice, comprising a frame plate, a grooved rod for mounting the frame plate on one side of the back of the frame plate, a servo motor on one side of the top of the frame plate, the output end of the servo motor being connected to a yarn bobbin via a shaft, a plurality of positioning rings being fixedly connected to one side of the bottom of the frame plate, the positioning rings being located below the yarn bobbin, and a cleaning device for collecting and cleaning waste yarn remaining on the outer surface of the yarn bobbin being provided on one side of the frame plate.
[0006] Preferably, the cleaning device includes a housing, which is fixed to the back of the frame plate. A servo motor is provided on one side of the outer surface of the housing. Several fan blades are fixed to the output end of the servo motor through a coupling. A through groove is opened on the side of the frame plate near the housing. A filter screen is fixedly connected to the inner wall of the through groove. An arc-shaped collection plate is fixedly connected to the side of the outer surface of the frame plate near the through groove. The collection plate is located below the through groove.
[0007] The aforementioned components achieve the following effects: By setting the fan blades, when using the yarn storage device, the yarn output from the rotor spinning machine passes through several positioning rings on one side of the bottom of the frame plate and then enters the outer surface of the yarn bobbin. The servo motor drives the yarn bobbin to rotate, winding the yarn around the outer surface of the yarn bobbin for storage. When the yarn storage device is working, the servo motor on one side of the housing can drive the fan blades to rotate. The rotation of the fan blades generates negative pressure suction, drawing the waste yarn attached to the outer surface of the yarn bobbin towards the through groove on one side of the frame plate. Air passes through the filter screen and through the through groove to the other side of the housing. The waste yarn will stay and attach to the outer surface of the filter screen or fall into the inside of the collection plate. When changing the yarn bobbin, the operation of the servo motor is stopped, and the waste yarn on the outer surface of the filter screen and the waste yarn inside the collection plate are cleaned.
[0008] Preferably, the internal shape of the through groove is conical, with the end of the through groove furthest from the shell being smaller than the end closest to the shell.
[0009] The effect achieved by the above components is that by setting a conical through groove, the fan blades can generate a stronger suction force on the through groove when rotating.
[0010] Preferably, a first rotating shaft is rotatably connected to the side of the frame plate near the through groove. A torsion spring is provided on the outer surface of the first rotating shaft. The two ends of the torsion spring are fixedly connected to one side of the first rotating shaft and one side of the frame plate, respectively. A brush rod is fixedly connected to the outer surface of the first rotating shaft. A plurality of hard bristles are provided on the side of the brush rod facing the frame plate. A gear is fixedly connected to the end of the first rotating shaft away from the brush rod. A toothed rod is slidably connected to the inner wall of the frame plate. The top end of the toothed rod meshes with the outer surface of the gear.
[0011] The effect achieved by the above components is as follows: during the cleaning process, the rack can be pulled to slide away from the inner wall of the frame plate. The rack drives the gear and the first rotating shaft to rotate, controlling the brush rod at one end of the first rotating shaft to rotate downward to clean the outer surface of the filter screen. When the first rotating shaft rotates, the torsion spring will deform. After the rack is released, the torsion spring returns to its original shape, which can drive the first rotating shaft to slowly rotate back to its original position.
[0012] Preferably, an auxiliary hook is fixedly connected to one end of the rack, and the auxiliary hook is located at the end of the rack away from the frame plate.
[0013] The effect achieved by the above components is that the hand hook at the auxiliary hook can more conveniently pull the rack to control the rotation of the rack and the first rotating shaft.
[0014] Preferably, a pad made of rubber is fixedly connected to the side of the frame plate near the auxiliary hook.
[0015] The effect achieved by the above components is as follows: after the auxiliary hook is pulled to control the movement of the rack and drive the first rotating shaft to rotate, the torsion spring drives the first rotating shaft to rotate and the rack moves towards the frame plate. When the auxiliary hook approaches the frame plate, it will contact the outer surface of the rubber pad. The pad buffers the movement of the auxiliary hook and the rack, avoiding direct collision between the rack and the frame plate.
[0016] Preferably, an auxiliary device is provided on one side of the top of the shelf. The auxiliary device includes a second rotating shaft, the two ends of which are rotatably connected to one side of the top of the shelf. A coil spring is provided at one end of the second rotating shaft, and the two ends of the coil spring are fixedly connected to one side of the second rotating shaft and one side of the top of the shelf, respectively. A guide ring is fixedly connected to the side of the second rotating shaft away from the top of the shelf.
[0017] The effect achieved by the above components is as follows: when using the yarn storage device, the yarn output from the yarn bobbin can pass through the inside of the guide ring. When the tension changes during the movement of the yarn, it can pull the guide ring to rotate through the second rotating shaft. The coil spring at one end of the second rotating shaft can limit the rotation angle of the guide ring, so as to avoid the yarn from being pulled too much and breaking when the tension changes.
[0018] Preferably, the inner wall of the guide ring has arc-shaped edges at both the upper and lower ends.
[0019] The effect achieved by the above components is that by setting the upper and lower edges of the inner wall of the guide ring to be arc-shaped, the yarn moves more smoothly against the inner wall of the guide ring and the surface is less prone to wear.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, a cleaning device is installed. When the yarn storage device is working, the servo motor located on the back of the frame plate drives the fan blades to rotate, generating negative pressure suction. This draws the waste yarn attached to the outer surface of the yarn tube towards the filter screen on the inner wall of the channel, thus minimizing the amount of waste yarn attached to the outer surface of the yarn tube and affecting the normal use of the yarn storage device.

[0023] Example 1, as Figure 1-3 As shown, a yarn storage device for a rotor spinning machine includes a frame plate 1. A groove rod for mounting the frame plate 1 is provided on one side of the back of the frame plate 1. A servo motor 4 is provided on one side of the top of the frame plate 1. The output end of the servo motor 4 is connected to a yarn cylinder 5 through a shaft. Several positioning rings 6 are fixedly connected to one side of the bottom of the frame plate 1. The positioning rings 6 are located below the yarn cylinder 5. A cleaning device 2 is provided on one side of the frame plate 1 to facilitate the collection and cleaning of waste yarn remaining on the outer surface of the yarn cylinder 5.
[0024] Reference Figure 1-6As shown in this embodiment: the cleaning device 2 includes a housing 23, which is fixed to the back of the frame plate 1. A servo motor 24 is provided on one side of the outer surface of the housing 23. Several fan blades 25 are fixed to the output end of the servo motor 24 via a coupling. A through groove 21 is provided on the side of the frame plate 1 near the housing 23. A filter screen 26 is fixedly connected to the inner wall of the through groove 21. An arc-shaped collecting plate 22 is fixedly connected to the side of the outer surface of the frame plate 1 near the through groove 21. The collecting plate 22 is located below the through groove 21. By setting the fan blades 25, when using the yarn storage device, the yarn output from the rotor spinning machine passes through several positioning rings 6 on one side of the bottom of the frame plate 1 and then enters the outer surface of the yarn tube 5. The servo motor 4 drives the yarn tube 5 to rotate, winding the yarn around the outer surface of the yarn tube 5 for yarn storage. When the yarn storage device is working, the servo motor 24 on one side of the housing 23 can be operated. The servo motor 24 drives the fan blades 25 to rotate, generating negative pressure suction to draw the waste yarn attached to the outer surface of the yarn tube 5 towards the through groove 21 on one side of the frame plate 1. Air passes through the filter screen 26 and through the through groove 21 to the other side of the housing 23. The waste yarn stays and adheres to the outer surface of the filter screen 26 or falls into the inside of the collection plate 22. When replacing the yarn tube 5, the operation of the servo motor 24 is stopped to clean the waste yarn on the outer surface of the filter screen 26 and the waste yarn inside the collection plate 22. By setting up the cleaning device 2, the servo motor 24 located on the back side of the frame plate 1 is operated to drive the fan blades 25 to rotate and generate negative pressure suction when the yarn storage device is working, drawing the waste yarn attached to the outer surface of the yarn tube 5 towards the filter screen 26 on the inner wall of the through groove 21, so as to avoid too much waste yarn attached to the outer surface of the yarn tube 5 and affecting the normal use of the yarn storage device.
[0025] Reference Figure 2-6As shown in this embodiment: the internal shape of the through groove 21 is conical, and the end of the through groove 21 away from the housing 23 is smaller than the end near the housing 23. By setting the conical through groove 21, the fan blade 25 can generate a stronger suction force on the through groove 21 when it rotates. A first rotating shaft 27 is rotatably connected to the side of the frame plate 1 near the through groove 21. A torsion spring 28 is provided on the outer surface of the first rotating shaft 27. The two ends of the torsion spring 28 are fixedly connected to one side of the first rotating shaft 27 and one side of the frame plate 1, respectively. A brush rod 29 is fixedly connected to the outer surface of the first rotating shaft 27. Several hard bristles are provided on the side of the brush rod 29 facing the frame plate 1. The first rotating shaft 27 is far from the bristles. One end of the brush rod 29 is fixedly connected to a gear 210, and a toothed rod 211 is slidably connected to the inner wall of the frame plate 1. The top end of the toothed rod 211 meshes with the outer surface of the gear 210. During the use of the cleaning device 2, the toothed rod 211 can be pulled to slide away from the frame plate 1 on the inner wall of the frame plate 1. The toothed rod 211 drives the gear 210 and the first rotating shaft 27 to rotate, controlling the brush rod 29 at one end of the first rotating shaft 27 to rotate downward to clean the outer surface of the filter screen 26. When the first rotating shaft 27 rotates, the torsion spring 28 will deform. After the toothed rod 211 is released, the torsion spring 28 returns to its original shape, which can drive the first rotating shaft 27 to slowly rotate back to its original position.
[0026] Reference Figure 2-6 As shown in this embodiment: an auxiliary hook 212 is fixedly connected to one end of the toothed rod 211. The auxiliary hook 212 is located at the end of the toothed rod 211 away from the frame plate 1. By using a hand hook at the auxiliary hook 212, it is easier to pull the toothed rod 211 to control the rotation of the toothed rod 211 and the first rotating shaft 27. A pad 213 is fixedly connected to the side of the frame plate 1 near the auxiliary hook 212. The pad 213 is made of rubber. After pulling the auxiliary hook 212 to control the movement of the toothed rod 211 and drive the first rotating shaft 27 to rotate, the torsion spring 28 drives the first rotating shaft 27 to rotate and the toothed rod 211 to move towards the frame plate 1. When the auxiliary hook 212 is close to the frame plate 1, it will contact the outer surface of the rubber pad 213. The pad 213 buffers the movement of the auxiliary hook 212 and the toothed rod 211, avoiding direct collision between the toothed rod 211 and the frame plate 1.
[0027] Reference Figure 1-4As shown in this embodiment: an auxiliary device 3 is provided on one side of the top of the frame plate 1. The auxiliary device 3 includes a second rotating shaft 31. Both ends of the second rotating shaft 31 are rotatably connected to one side of the top of the frame plate 1. A coil spring 32 is provided at one end of the second rotating shaft 31. The two ends of the coil spring 32 are fixedly connected to one side of the second rotating shaft 31 and one side of the top of the frame plate 1, respectively. A guide ring 33 is fixedly connected to the side of the second rotating shaft 31 away from the top of the frame plate 1. When using the yarn storage device, the yarn output from the yarn cylinder 5 can pass through the interior of the guide ring 33. When the tension changes during the movement of the yarn, it can pull the guide ring 33 to rotate through the second rotating shaft 31. The coil spring 32 at one end of the second rotating shaft 31 can limit the rotation angle of the guide ring 33, so as to avoid the yarn from being pulled too much and breaking when the tension changes. The upper and lower edges of the inner wall of the guide ring 33 are arc-shaped. By setting the upper and lower edges of the inner wall of the guide ring 33 to be arc-shaped, the yarn moves more smoothly when it adheres to the inner wall of the guide ring 33 and the surface is less likely to be worn.
[0028] Working principle: When using the yarn storage device, the yarn output from the rotor spinning machine passes through several positioning rings 6 on one side of the bottom of the frame plate 1 and then enters the outer surface of the yarn tube 5. The servo motor 4 drives the yarn tube 5 to rotate, winding the yarn around the outer surface of the yarn tube 5 for yarn storage. The yarn output from the surface of the yarn tube 5 can pass through the inside of the guide ring 33. When the tension changes during the movement of the yarn, it can pull the guide ring 33 to rotate through the second rotating shaft 31. The coil spring 32 at one end of the second rotating shaft 31 can limit the rotation angle of the guide ring 33, so as to avoid the yarn from being broken due to excessive pulling when the tension changes. The servo motor 24 on one side of the operating housing 23 drives the fan blade 25 to rotate. The rotation of the fan blade 25 generates negative pressure suction, which removes the waste yarn attached to the outer surface of the yarn tube 5. The yarn is drawn towards the through groove 21 on one side of the frame plate 1. Air passes through the filter screen 26 and through the through groove 21 to the other side of the housing 23. Waste yarn will stay and adhere to the outer surface of the filter screen 26 or fall into the inside of the collection plate 22. When changing the yarn spool 5, the operation of the servo motor 24 is stopped. The rack 211 can be pulled to slide away from the frame plate 1 on the inner wall. The rack 211 drives the gear 210 and the first rotating shaft 27 to rotate. The brush rod 29 at one end of the first rotating shaft 27 is controlled to rotate downward to clean the outer surface of the filter screen 26. At the same time, the waste yarn inside the collection plate 22 can be cleaned. When the first rotating shaft 27 rotates, the torsion spring 28 will deform. After the rack 211 is released, the torsion spring 28 returns to its original shape, which can drive the first rotating shaft 27 to slowly rotate back to its original position.
