Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to a uniform winding device for a drawing frame. Background Technology

[0002] The function of a drawing frame is to improve the internal structure of the sliver, thereby increasing its long-segment uniformity and reducing weight unevenness. It also straightens and parallels the fibers in the sliver, reduces hooks, ensures the fineness meets specifications, and ensures uniform mixing of different types or qualities of raw materials to achieve the specified blending ratio. Drawing frames are broadly classified into two categories based on their drafting mechanism: roller drafting frames and carding frames.

[0003] After cotton lint is combined into sliver by the drawing frame, it exits the frame through the yarn exit and passes through the guide tube before winding onto the take-up roller. The take-up roller rotates to wind the sliver. To ensure the sliver is evenly wound onto the take-up roller and to prevent it from piling up in one place, thus increasing the amount of sliver wound, a moving device is installed on the take-up roller. While the take-up roller is winding the sliver, the moving device moves the sliver along the axial direction of the take-up roller, moving it to different positions on the roller, thus ensuring the sliver is wound in different locations. However, this movement also causes the sliver to move laterally relative to the guide tube as it passes through it. This causes wear on the sliver at the edge of the guide tube opening, reducing the sliver's quality. Utility Model Content

[0004] The purpose of this invention is to provide a uniform winding device for a drawing frame, which has the advantage of reducing wear on the cotton sliver at the edge of the guide tube opening during uniform winding.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A uniform winding device for a drawing frame includes a take-up roller rotatably connected to the drawing frame, a rotating arm hinged near the yarn exit of the drawing frame, the rotating arm rotating in a vertical plane, a rotating shaft hinged to the end of the rotating arm, the rotation axis of the rotating shaft being parallel to the rotation axis of the rotating arm, a bushing integrally formed on the rotating shaft, the central axis of the bushing being perpendicular to the rotation axis of the rotating shaft, a connecting rod rotatably connected to the bushing via a connecting piece, a horizontal guide rod fixedly connected to the drawing frame, the guide rod being parallel to the take-up roller, and the axis of the guide rod being parallel to the rotation axis of the rotating arm, a mounting base slidably connected to the guide rod, the mounting base having a channel inside, the mounting base being hinged to the end of the connecting rod via a universal joint, a drive mechanism between the drawing frame and the mounting base, a plurality of sleeves fixedly connected to the connecting rod via a connecting piece, and a sleeve being fixedly connected to the rotating arm.

[0006] Using the above technical solution, after the cotton sliver is drawn, it comes out of the yarn outlet of the drawing frame, then passes through the channel inside the second sleeve, the first sleeve, and the mounting base, and is then wound onto the take-up roller. The take-up roller rotates, pulling the cotton sliver along the channel inside the first sleeve, the second sleeve, and the mounting base. The cotton sliver is restricted by the two sleeves and the channel and will not unravel. The take-up roller winds the cotton sliver around its body. At the same time, the drive mechanism drives the mounting base to move back and forth on the guide rod. The mounting base drives the connecting rod to swing back and forth and left and right on the mounting base through the universal joint. The connecting rod drives the rotating arm to rotate through the rotating shaft and bushing. The rotating arm and the connecting rod drive the first sleeve and the second sleeve to move. The mounting base drives the cotton sliver to move through the channel. While the cotton sliver moves laterally, the sleeve swings, reducing the lateral relative movement between the sleeve and the cotton sliver and preventing wear on the cotton sliver from the edge of the sleeve opening. After the take-up roller winds the cotton sliver around its upper part once, the mounting base moves the cotton sliver to another part of the take-up roller body, where the take-up roller winds it again. After the mounting base moves the cotton sliver a certain distance, the drive mechanism moves the mounting base and the cotton sliver back to the place where the take-up roller initially winds the cotton sliver, and the take-up roller continues to wind the cotton sliver, thus evenly winding the cotton sliver around its roller body.

[0007] Preferably, the drive mechanism comprises a gear, a rack, and a motor, wherein the rack is fixedly connected to the frame, the motor is fixedly connected to the mounting base, the gear is fixedly connected to the output shaft of the motor, and the gear and rack mesh with each other.

[0008] Using the above technical solution, the motor drives the gear to rotate, the gear exerts a force on the rack, and the force between the two causes the gear and the mounting base to move. The mounting base then moves the cotton sliver, thereby causing the take-up roller to evenly wind it up.

[0009] Preferably, the connector has a bolt and a nut, the bolt passes through the connecting rod and the bushing, the bolt is rotatably connected to the connecting rod and the bushing, the nut is threaded onto the bolt, and the bushing and the end of the connecting rod are located between the nut and the tail of the bolt.

[0010] By using the above technical solution, the connecting rod and the shaft can rotate relative to each other by passing the bolt through the connecting rod and the bushing, and then tightening the nut on the bolt.

[0011] Preferably, the second connector is a fixing clamp, the connecting rod passes through the clamping hole of the fixing clamp, the opening of the fixing clamp is threaded with a bolt, and the first sleeve is fixedly connected to the fixing clamp.

[0012] Using the above technical solution, by tightening the bolts at the opening of the fixing clamp, the two side walls of the fixing clamp opening can be brought closer together, clamping the connecting rod passing through the fixing clamp, thereby fixing the sleeve one on the connecting rod. The bolts can be loosened to reduce the force of the fixing clamp on the connecting rod. Relative to the connecting rod, the fixing clamp moves, and the fixing clamp drives the sleeve one to move, adjusting the distance between two adjacent sleeves one on the connecting rod, thus better restricting the cotton strip.

[0013] Preferably, a conduit is fixedly connected to the outlet of the mounting base channel.

[0014] Using the above technical solution, the cotton lint strip passes through the mounting seat channel and then through the guide tube, which further guides the cotton lint strip and prevents it from spreading out.

[0015] Preferably, the driving mechanism can also be a lead screw and a second motor, with the second motor fixedly connected to the frame, the lead screw being horizontally rotatably connected to the frame, and the mounting base being fixedly connected to the lead screw slider.

All technical solutions falling within the scope of this utility model should be considered within the protection scope of this utility model.

[0019] See Figures 1 to 7 A uniform winding device for a drawing frame is disclosed, wherein the drawing frame 1 is rotatably connected to a take-up roller 2. A rotating arm 3 is hinged to the drawing frame 1 near its yarn exit point, and the rotating arm 3 rotates in a vertical plane. A rotating shaft 4 is hinged to the end of the rotating arm 3, and the rotation direction of the rotating shaft 4 is parallel to the rotation direction of the rotating arm 3. A bushing 5 is integrally formed on the rotating shaft 4, and the central axis of the bushing 5 is perpendicular to the rotation axis of the rotating shaft 4. A connecting rod 6 is also included, which is rotatably connected to the bushing 5 by a bolt 17 and a nut 18. The bolt 17 passes through the connecting rod 6 and the bushing 5, and the nut 18 is threaded onto the bolt 17. The bushing 5 and the end of the connecting rod 6 are located between the nut 18 and the tail of the bolt 17. A horizontal guide rod 7 and a rack 13 are fixedly connected to the drawing frame 1. The guide rod 7 is parallel to the take-up roller 2, and the axis of the guide rod 7 is parallel to the rotation axis of the rotating arm 3. A mounting base 8 is slidably connected to the guide rod 7, and a channel is opened inside the mounting base 8. A guide tube 20 is fixedly connected to the outlet of the channel of the mounting base 8. Mounting base 8 is hinged to the end of connecting rod 6 via universal joint 9. Motor 14 is fixedly connected to mounting base 8. Gear 12 is fixedly connected to the output shaft of motor 14. Gear 12 and rack 13 mesh with each other. Multiple fixing clips 19 pass through connecting rod 6. Bolts 17 are threaded into the opening of fixing clip 19. Tightening bolts 17 can bring the two side walls of the opening of fixing clip 19 together, clamping connecting rod 6, thereby fixing fixing clip 19 to connecting rod 6. Each fixing clip 19 is fixedly connected to sleeve 10, and rotating arm 3 is fixedly connected to sleeve 2 11.

[0020] Working principle: After the cotton sliver is drawn, it exits from the yarn outlet of the drawing frame 1, then passes through the channels inside the sleeve 11, sleeve 10, and mounting base 8, and the guide tube 20 at the channel opening, and is then wound onto the take-up roller 2. The take-up roller 2 rotates, pulling the cotton sliver along the channels inside the sleeve 10, sleeve 11, and mounting base 8. The cotton sliver is restricted by the two sleeves and the channels and will not unravel. The take-up roller 2 winds the cotton sliver around its body. Simultaneously, the drive mechanism drives the mounting base 8 to reciprocate on the guide rod 7. The mounting base 8, through the universal joint 9, drives the connecting rod 6 to swing back and forth and left and right on the mounting base 8. The connecting rod 6 drives the rotating arm 3 to rotate through the rotating shaft 4 and the bushing 5. The rotating arm 3 and the connecting rod 6 drive the sleeve 10 and sleeve 2 11 to move. The mounting base 8 drives the cotton sliver to move through the channel. While the cotton sliver moves laterally, the sleeve swings to reduce the lateral relative movement between the sleeve and the cotton sliver, preventing wear on the cotton sliver by the sleeve opening edge and reducing its quality. After the take-up roller 2 has wound the cotton sliver around its upper part once, the mounting base 8 drives the cotton sliver to other parts of the take-up roller 2 to be wound up again. After the mounting base 8 has driven the cotton sliver to move a certain distance, the drive mechanism drives the mounting base 8 and the cotton sliver back to the place where the take-up roller initially wound the cotton sliver. The take-up roller 2 continues to wind up the cotton sliver, thus evenly winding the cotton sliver around its roller body.

[0021] See Figure 7 The driving mechanism can also be a lead screw 15 and a second motor 16. The second motor 16 is fixedly connected to the frame, the lead screw 15 is horizontally rotatably connected to the frame, and the mounting base 8 is fixedly connected to the slider of the lead screw 15.
