Technical Field
[0001] The utility model relates to the technical field of polyester-cotton yarn guiding, in particular to a yarn guiding device for a spinning frame in the production of polyester-cotton yarns. Background Technique
[0002] The yarn guiding device of the spinning frame is indeed one of the key components of the spinning frame. Its main function is to guide the yarn to ensure that the yarn can be transmitted orderly and stably between the various working components of the spinning frame, so that it will not be entangled, knotted or deviated from the track. Polyester-cotton yarn is a yarn spun from a blend of polyester fibers and cotton fibers. The spinning frame plays a very important role in the production of polyester-cotton yarn.
[0003] The existing yarn guiding devices for spinning frames in the production of polyester-cotton yarns usually do not actively control the outgoing wire. Some yarn guiding devices use a rotatable coil fixing table, which drives the coil fixing table to rotate after the polyester-cotton yarn is subjected to a tensile force. Not only can the tensile force received by the polyester-cotton yarn not be adjusted, but it is also possible that the polyester-cotton yarn in the middle breaks and cannot be stopped in time, resulting in yarn explosion. Some other yarn guiding devices use a yarn roller in a vertical unwinding mode, but still cannot ensure that the tensile force received by the polyester-cotton yarn remains stable during the wire guiding process.
[0004] Therefore, aiming at the problem that the existing yarn guiding devices for spinning frames in the production of polyester-cotton yarns cannot ensure that the tensile force received by the polyester-cotton yarn remains stable during the wire guiding process, a yarn guiding device for a spinning frame in the production of polyester-cotton yarns can be designed, which can adjust the speed of releasing the polyester-cotton yarn according to the magnitude of the tensile force received by the polyester-cotton yarn. Content of the Utility Model
[0005] In order to overcome the problem that the existing yarn guiding devices for spinning frames in the production of polyester-cotton yarns cannot ensure that the tensile force received by the polyester-cotton yarn remains stable during the wire guiding process.
[0006] The technical solution of the utility model is: a yarn guiding device for a spinning frame in the production of polyester-cotton yarns, which includes a workbench.

A sliding groove is opened on the surface of the support plate. Steering wheels are installed on both the left and right sides of the support plate. A wetting box is installed on the left side of the upper end of the workbench. Limiting scraping plates are installed on both the left and right ends of the wetting box. A water storage tank is installed at the front end of the wetting box. A main water pipe is installed on the upper end of the water storage tank.

[0007] Preferably, the tension induction box senses the tension applied to the force-bearing wheel, and the tension induction box controls the rotation speed of the servo motor. The servo motor drives the fixed disk to rotate for wire payout. When the tension received by the tension induction box is too small, the servo motor is controlled to decelerate, so that the polyester-cotton yarn is tightened to prevent the polyester-cotton yarn from vibrating and winding during the transmission process. When the tension received by the tension induction box is too large, the servo motor is controlled to accelerate, so that the polyester-cotton yarn is relaxed to prevent the polyester-cotton yarn from breaking due to excessive tension. Water is injected into the wetting box through the water storage tank to keep the humidity of the wetting sponge. The polyester-cotton yarn passes through the wetting box to wet the wetting sponge, and then the limiting scraper scrapes off the excess water to eliminate the static electricity of the polyester-cotton yarn.
[0008] Preferably, a fixed plate is installed inside the support frame, and a servo motor is installed at the upper end of the fixed plate. The lower end of the fixed disk is fixedly connected to the output end of the servo motor.
[0009] Preferably, a sliding groove is formed inside the fixed disk, an anti-slip opening is formed on the side of the fixed disk, both the left and right sides inside the sliding groove are slidably connected with fixing rods, the two fixing rods are connected by springs, and anti-sliding blocks are installed on the sides of the fixing rods.

[0015] 1. For the yarn guiding device of the fine spinning machine for producing polyester-cotton yarn, the pressure sensor senses the tension applied to the force-bearing wheel, and the control terminal controls the servo motor to drive the fixed disk to rotate for wire payout. When the tension received by the pressure sensor is too small, the servo motor is controlled to decelerate, so that the polyester-cotton yarn is tightened to prevent the polyester-cotton yarn from vibrating and winding during the transmission process. When the tension received by the pressure sensor is too large, the servo motor is controlled to accelerate, so that the polyester-cotton yarn is relaxed to prevent the polyester-cotton yarn from breaking due to excessive tension, avoiding production interruption and time waste caused by frequent knotting and yarn breakage.

The main water pipe 10 supplies water, and the water storage tank 9 injects water into the wetting box 7. The polyester-cotton yarn passes through the wetting box 7 for wetting, eliminating the static electricity of the polyester-cotton yarn and preventing the influence of static electricity of the polyester-cotton yarn on subsequent work.
[0026] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 , inside the support frame 2, a fixing plate 21 is installed.

[0028] When working, the polyester-cotton yarn roll is installed on the fixed disk 3, the sleeve inside the polyester-cotton yarn roll is fixed by pushing the fixed rod 34 through the spring. Through the spring connection, when the external device starts to pull the polyester-cotton yarn, the force-receiving slider 54 receives the pulling force of the force-receiving wheel 52, and the force-receiving slider 54 slides downward to press the pressure sensor 56. Both the pressure sensor 56 and the servo motor 31 are connected to the control terminal, which is convenient to control the rotation speed of the servo motor 31.

When the pressure received by the pressure sensor 56 is too small, the servo motor 31 is controlled to decelerate to tighten the polyester-cotton yarn and prevent the polyester-cotton yarn from vibrating and winding during the transmission process. When the pressure received by the pressure sensor 56 is too large, the servo motor 31 is controlled to accelerate to loosen the polyester-cotton yarn and prevent the polyester-cotton yarn from breaking due to excessive pulling force, avoiding production interruption and time waste caused by frequent knotting and yarn breakage.
