[0002] A drawing frame is a machine that improves the internal structure of sliver, thereby increasing the uniformity of its long segments and reducing weight unevenness. It straightens and parallels the fibers in the sliver, reduces hooks, ensures the fineness meets specifications, and mixes different types or qualities of raw materials evenly to achieve the specified mixing ratio. It plays a very important role in yarn processing. A drawing frame consists of a feeding section, a drafting section, a sliver forming section, and some automatic devices, among which the drafting section is used to pull the yarn.

[0003] The drafting mechanism of existing drawing frames cannot adjust the pressure on the yarn, has a narrow range of applications, is inconvenient to use, and cannot automatically clean impurities from the surface of the rollers and feed rollers, which can easily affect product quality. Utility Model Content

[0004] The purpose of this invention is to provide a drafting mechanism for a high-speed drawing frame for pure polyester yarn, which solves the problems of not being able to adjust the pressure of the drafting mechanism on the yarn and not being able to automatically clean impurities from the surface of the rollers and feed rollers.

[0005] To achieve the above objectives, a drafting mechanism for a high-speed drawing frame for pure polyester yarn is provided, comprising: a base, mounting plates fixedly connected to both sides of the upper surface of the base, a mounting box fixedly connected to the side of the mounting plate, a first cylinder fixedly connected to the side of the mounting box, a push plate slidably connected inside the mounting box, a push plate fixedly connected to the output end of the first cylinder on the side of the push plate, push rods fixedly connected to both ends of the push plate, mounting grooves opened inside the two mounting plates, second shaped blocks slidably connected inside the two mounting grooves, one end of the second shaped block fixedly connected to the end of the push rod away from the push plate, three through slots penetrating through the inner walls of the two mounting grooves, springs fixedly connected to the bottom surfaces of the through slots, moving blocks fixedly connected to the upper ends of the springs, upper rollers rotatably connected relative to the two moving blocks, three lower rollers rotatably connected between the two mounting plates, and a first shaped block slidably connected inside the two mounting grooves, the side of the first shaped block fixedly connected to the side of the moving block, and the lower surface of the second shaped block slidably connected to the upper surface of the first shaped block. This facilitates adjustment of the pressure on the workpiece, increases the applicability of the device, and has a simple structure.

[0006] A mounting base plate is fixedly connected between the two mounting plates. A second cylinder is fixedly connected to the upper surface of the mounting base plate, and a third cylinder is fixedly connected to the upper surface of the base. Cleaning plates are fixedly connected to the output ends of the second and third cylinders. Three mounting grooves are opened on the side of the two cleaning plates facing downwards.

[0007] According to the drafting mechanism of a high-speed drawing frame for pure polyester yarn, two cleaning plates are respectively arranged on the upper and lower parts of the lower roller. Two first limiting rods are fixedly connected to the upper surface of the upper cleaning plate, and the outer side of the first limiting rods is slidably connected to the inside of the mounting base. Two second limiting rods are fixedly connected to the lower surface of the lower cleaning plate, and the outer side of the second limiting rods is slidably connected to the inside of the base, so as to facilitate the stable up and down movement of the cleaning plate.

[0008] According to the drafting mechanism of a high-speed drawing frame for pure polyester yarn, one end of each of the three lower rollers extends to the outside of the mounting plate and is fixedly connected to a gear. The three gears are externally meshed with a timing belt to facilitate synchronous movement of the lower rollers.

[0009] According to the drafting mechanism of a high-speed drawing frame for pure polyester yarn, a gearbox is fixedly connected to the side of one of the mounting plates. The gearbox is located outside the gears, and a second servo motor is fixedly connected to the side of the gearbox. The output end of the second servo motor is fixedly connected to the side of one of the gears. The gearbox facilitates the protection of the internal gears, and the second servo motor facilitates the provision of power.

[0010] According to the drafting mechanism of a high-speed drawing frame for pure polyester yarn, two traction rollers are rotatably connected between the two mounting plates. Each traction roller has an annular groove on its outer side. A first servo motor is fixedly connected to the side of one of the mounting plates, and one end of one of the traction rollers is fixedly connected to the output end of the first servo motor, which facilitates the separation of the traction yarns and facilitates subsequent processing.

[0012] According to the drafting mechanism of a high-speed drawing frame for pure polyester yarn, a controller is fixedly connected to the side of one of the mounting plates to facilitate the operation of the control device.

[0013] According to the drafting mechanism of a high-speed drawing frame for pure polyester yarn, support legs are fixedly connected to the four corners of the lower surface of the base.

[0014] The above-mentioned solution has the following beneficial effects:

[0015] 1. The extension and retraction of the first cylinder drives the push plate and push rod to move, which facilitates the movement of the second irregular block. The inclined surface of the second irregular block cooperates with the inclined surface of the first irregular block to facilitate the downward movement of the first irregular block and the moving block. The elasticity of the spring facilitates the upward movement of the upper roller, which facilitates the adjustment of the distance between the lower roller and the upper roller, and the adjustment of the pressure on the workpiece. This makes it easy to adapt to different types of workpieces and increases the applicability of the device.

[0016] 2. The second and third cylinders extend and retract to facilitate the movement of the cleaning plate. The cleaning cloth inside the mounting groove facilitates the removal of impurities adhering to the surface of the lower roller and upper roller, preventing impurities from affecting product quality.
