Description

Technical Field

[0001] This utility model relates to the field of spinning technology, and in particular to the sliver feeding mechanism of a combing machine. Background Technology

[0002] The main function of a combing machine is to remove shorter fibers and knots (such as neps, wool particles, grass clippings, cocoon skins, etc.) from the fibers, making them straighter and more parallel, ultimately producing combed slivers with a relatively uniform thickness. In the textile industry, combing machines use a series of mechanical and electrical components to finely comb cotton slivers, wool slivers, or synthetic fiber slivers, removing surface impurities and short fibers, making them smoother and more uniform.

[0003] After multiple cotton slivers are combed by the combing machine, they are combined into a single combed sliver. The combined combed sliver is then fed into the coiling mechanism of the combing machine for coiling and feeding, so that the combed sliver is evenly wound into the collecting drum. When placing the combed sliver into the coiling mechanism, it must first be threaded into the guide tube. The combed sliver moves along the guide tube to a pair of feed rollers in the coiling mechanism. The driven roller in the feed roller is removed, allowing the combed sliver to pass through the driving roller. The driven roller is then reinstalled, so that the two rollers clamp the combed sliver. The coiling mechanism drives the combed sliver to rotate, while the feed rollers drive the combed sliver downwards for feeding. Because the feed rollers need to be disassembled and reassembled, it is relatively troublesome and reduces work efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a sliver feeding mechanism for a combing machine, which has the advantage of making it easy to put the combed sliver into the sliver feeding mechanism.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A yarn feeding mechanism for a combing machine includes a combing machine, a support plate fixedly connected to the yarn outlet of the combing machine, a rotating platform below the support plate, a vertical pipe passing through the support plate and rotatably connected to the pipe, and rotating disks one and two fixedly connected to the upper and lower openings of the pipe respectively, with rotating disks one and two located on the upper and lower sides of the support plate respectively. A drive mechanism one is provided on the bottom side of the support plate and connected to the pipe. An L-shaped guide tube is fixedly connected to rotating disk two and communicates with the pipe. Two sets of connecting arms are connected to rotating disk two respectively. There are two connecting arms, namely connecting arm one and connecting arm two. The two sets of connecting arms are located on both sides of the guide tube. Connecting arm one is fixedly connected to rotating disk two, and connecting arm two is hinged to rotating disk two. A driving roller is rotatably connected between connecting arms one, and a driven roller is rotatably connected between connecting arms two. A driving mechanism two is connected to one of the connecting arms one. The driving mechanism two is drivenly connected to the driving roller. The driving roller and the driven roller are connected through a transmission mechanism. A horizontal worm is rotatably connected to the bottom surface of rotating disk two. A worm wheel is fixedly connected to one of the connecting arms two at its hinge point with rotating disk two. The worm wheel and worm are meshed.

[0007] Using the above technical solution, multiple cotton slivers are combed by a combing machine and then combined into a single combed sliver. This sliver exits from the combing machine's yarn outlet and passes through a support plate's pipe, moving it below the support plate. It then passes through a horizontal guide tube. The worm gear rotates, driving the connecting arm two to rotate via the worm wheel. The connecting arm two then rotates the driven roller away from the driving roller. The combed sliver passes between the two rollers. The worm gear rotates in the opposite direction, causing the driven roller to move closer to the driving roller, thus clamping the combed sliver between the two rollers. The process continues... A collection cylinder is placed on the platform. The rotating platform drives the collection cylinder to rotate. The second drive mechanism drives the active roller to rotate relative to the first connecting arm and the second rotating disk. The active roller drives the driven roller to rotate through the transmission mechanism. The two rollers pull the combed strips into the collection cylinder. At the same time, the first drive mechanism drives the pipe to rotate relative to the support plate. The pipe drives the two rotating disks to rotate. The second rotating disk drives the guide tube and the active roller and driven roller to rotate as a whole. As the combed strips fall, the guide tube drives the combed strips to rotate, thus placing the combed strips in a regular circle in the collection cylinder.

[0008] Preferably, the transmission mechanism is a gear, and the driving roller and the driven roller are respectively fixedly connected to gears, and the gears of the two are meshed.

[0009] Using the above technical solution, rotating the worm gear drives the driven roller to rotate away from the driving roller, while the gears of the two separate, allowing the combed sliver to pass between the two rollers. Rotating the worm gear in the opposite direction causes the driven roller to approach the driving roller, clamping the combed sliver between them. At the same time, the gears of the two mesh, and the second drive mechanism drives the driving roller to rotate. The driving roller drives the driven roller to rotate through the two meshing gears. The two rollers pull the combed sliver to move, feeding it.

[0010] Preferably, a mounting plate is fixedly connected to the yarn outlet of the combing machine, and a steering tube is fixedly connected to the mounting plate.

[0011] Using the above technical solution, after the cotton sliver is drawn through the comber, it is pulled out horizontally from the yarn outlet of the comber and then passed through the deflector tube. The combed sliver becomes vertical and then passes vertically through the pipe. The deflector tube guides and supports the combed sliver, preventing it from being worn by the edge of the yarn outlet of the comber and the edge of the pipe opening, and also preventing the combed sliver from spreading out.

[0012] Preferably, a handle is fixedly connected to the end of the worm gear.

[0013] The above technical solution facilitates the rotation of the worm gear. Attached Figure Description

[0023] See Figures 1 to 7 A yarn feeding mechanism for a combing machine 1 includes a combing machine 1, with a mounting plate 17 fixedly connected to the yarn outlet of the combing machine 1. A steering pipe 18 is fixedly connected to the mounting plate 17, and a support plate 2 is fixedly connected to the combing machine 1 below the steering pipe 18. A rotating platform is located below the support plate 2, and a vertical pipe 63 passes through the support plate 2, rotatably connected to the support plate 2. Rotating disk 4 and rotating disk 5 are fixedly connected to the upper and lower openings of the pipe 63, respectively, located on the upper and lower sides of the support plate 2. A motor 15 is fixedly connected to the bottom of the support plate 2, and the output shaft of the motor 15 is connected to the pipe 63 via a synchronous pulley and a synchronous belt. An L-shaped guide tube 7 is fixedly connected to the rotating disk 25, communicating with the pipe 63. Two sets of connecting arms are connected to the rotating disk 25, namely connecting arm 8 and connecting arm 9, with two arms in each set, located on both sides of the guide tube 7. Connecting arm 1 (8) is fixedly connected to rotating disk 2 (5), and connecting arm 2 (9) is hinged to rotating disk 2 (5). A drive roller 10 is rotatably connected between connecting arms 1 (8), and a driven roller 11 is rotatably connected between connecting arms 2 (9). A motor 2 (16) is fixedly connected to one of the connecting arms 1 (8), and the output shaft of motor 2 (16) is connected to the drive roller 10 via a synchronous pulley and belt. Gears 14 are fixedly connected to both the drive roller 10 and the driven roller 11, and these gears mesh. A horizontal worm gear 12 is rotatably connected to the bottom surface of rotating disk 2 (5), and a handle 19 is fixedly connected to the end of the worm gear 12. A worm wheel 13 is fixedly connected to one of the connecting arms 2 (9) at its hinge point with rotating disk 2 (5), and the worm wheel 13 meshes with the worm gear 12.

[0024] Working principle: After the cotton sliver passes through the combing machine 1, it is pulled horizontally out of the yarn outlet of the combing machine 1, then passes through the turning tube 18, turning the combed sliver vertically. It then passes vertically through the pipe 63 into the guide tube 7, and finally exits from the guide tube 7. The worm gear 12 is then rotated, which drives the connecting arm 9 to rotate via the worm wheel 13. The connecting arm 9 drives the driven roller 11 to rotate away from the driving roller 10, and then the combed sliver passes between the two rollers. The worm gear 12 is rotated in the opposite direction, causing the driven roller 11 to move closer to the driving roller 10, thus clamping the combed sliver between the two rollers. A collecting cylinder is placed on the rotating table. The rotating table drives the collection cylinder to rotate, and the second motor 16 drives the active roller 10 to rotate relative to the connecting arm 8 and the second rotating disk 5. The active roller 10 drives the driven roller 11 to rotate through the meshing gear 14. The two rollers pull the combed strips into the collection cylinder. At the same time, the first motor 15 drives the pipe 63 to rotate relative to the support plate 2. The pipe 63 drives the two rotating disks to rotate. The second rotating disk 5 drives the guide tube 7 and the active roller 10 and driven roller 11 to rotate as a whole. As the combed strips fall, the guide tube 7 drives the combed strips to rotate, thereby placing the combed strips in a regular circle in the collection cylinder.
