By installing the disassembly ring on the surface of the winding roller and removing the disassembly ring after the yarn on the surface of the winding roller is installed, the winding roller can be quickly replaced.

[0003] However, when the device is used to draw the yarn, the yarn is easily loosened, resulting in knots between the yarns. At the same time, the yarn is easily broken during the drawing process. Summary of the Invention

[0004] The purpose of the utility model is to provide a drafting device for textile yarns, which solves the problem that the yarns of the existing drafting device for textile yarns are easily loosened when the yarns are drafted, resulting in knots between the yarns, and the yarns are easily broken during the drafting process.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a drafting device for textile yarn, comprising a base, a supporting mechanism is provided at the upper end of the base, a pay-off roller is provided on the supporting mechanism, a support is welded to the upper end of the base, a take-up rod is rotatably connected to the inside of the support, a slide is slidably connected to the upper end of the base, a bracket is fixedly connected to the upper end of the slide, a tensioning mechanism is provided on the bracket, a motor is fixedly installed at the front end of the base, the output end of the motor passes through the base and is rotatably connected to the base, a screw is fixedly connected to the rear end of the output end of the motor, the screw and the base are rotatably connected, the lower end of the slide is fixedly connected to a guide block, and the guide block and the screw are threadedly connected.

[0006] The principle of the present invention is that when in use, the yarn on the pay-off roller is pulled, one end of the yarn is wound around the outside of the take-up rod, the screw ring and the slide cylinder are manually rotated to perform a threaded movement, thereby causing the screw ring to move down, the screw ring drives the sliding pin to move down, the sliding pin drives the sliding rod to move down, the sliding rod drives the sliding sleeve to move, the sliding sleeve drives the wheel seat to move, the wheel seat drives the pressure wheel to move, so that the pressure wheel and the yarn are in contact, the screw ring is continuously rotated to move the slide rod down, thereby causing the spring to be compressed and deformed, thereby causing the yarn to be compressed and stretched, and by rotating the screw ring and the slide cylinder to perform a threaded movement, the slide rod can be extended and retracted in the slide cylinder, thereby causing the spring to elastically move the sliding sleeve downward, thereby causing the pressure wheel to tension and stretch the yarn, so that the yarn is immersed in the water tank. The yarn is stretched and thinned in the water. At the same time, the water on the yarn makes the fine fibers in the yarn twisted more tightly, making the yarn less likely to break. When the take-up roller takes up the line, the pay-off roller rotates to pay off the line, and the adjusting lever is manually turned. The adjusting lever rotates and makes a threaded motion with the screw disk, so that the connecting rod drives the friction plate to contact the pay-off roller, and the friction between the friction plate and the pay-off roller is adjusted, so that the rotation friction of the pay-off roller can be adjusted to prevent the pay-off roller from rotating too fast and causing the yarn to loosen and knot. Then the motor is started to drive the screw to rotate, and the screw rotates and makes a threaded motion with the guide block, so that the guide block moves back and forth on the base, and the base drives the tensioning mechanism to move back and forth, so that the yarn is evenly wound on the take-up roller.

[0007] The beneficial effect of the utility model is that the adjusting rod and the screw disk are rotated to make a threaded movement, thereby making the connecting rod drive the friction plate and the pay-off roller to contact, and adjusting the friction between the friction plate and the pay-off roller, thereby making the rotational friction of the pay-off roller adjustable, and preventing the pay-off roller from rotating too fast and causing the yarn to loosen and knot;

[0008] By rotating the screw ring and the slide cylinder to make a threaded motion, the slide rod can be extended and retracted in the slide cylinder, and the spring can elastically move the slide sleeve downward, so that the pressure wheel can tension and stretch the yarn, so that the yarn is immersed in the water in the water tank and is stretched and stretched. At the same time, the water on the yarn makes the fine hairs in the yarn twisted more tightly, making the yarn less likely to break.

[0009] Furthermore, a motor is fixedly mounted on the front end of the support, a rotating shaft of the motor passes through the support and is rotatably connected to the support, and the rotating shaft of the motor is fixedly connected to the wire take-up roller. By arranging the motor, the wire take-up roller is driven to rotate.

[0010] Furthermore, a water tank is fixedly mounted on the upper end of the slide, and a guide wheel is provided on the water tank. The yarn is supported by the guide wheel.

[0011] Furthermore, the support mechanism includes a side plate, the upper end of which is fixedly connected to the side plate, the side plate being rotatably connected to the pay-off roller, the surface of which is fixedly connected to the support plate, the interior of which is mounted with an adjustment rod via a bearing, the exterior of which is threadedly connected to a screw disk, the interior of which is slidably connected to a friction plate, and the surface of which is fixedly connected to a connecting rod. By rotating the adjustment rod and the screw disk to form a threaded motion, the connecting rod drives the friction plate into contact with the pay-off roller, adjusting the friction between the friction plate and the pay-off roller, thereby adjusting the rotational friction of the pay-off roller, thereby preventing the pay-off roller from rotating too fast, causing the yarn to loosen and tangle.

[0012] Furthermore, the connecting rod is slidably connected to the side plate, and the connecting rod is fixedly connected to the screw plate. By arranging the connecting rod, the movement of the friction plate is controlled.

[0013] Furthermore, the tensioning mechanism includes a slide cylinder, the lower end of the bracket is fixedly connected to the slide cylinder, the interior of the slide cylinder is slidably connected to a slide rod, the surface of the slide rod is fixedly connected to a slide pin, the outer side of the slide cylinder is connected to a screw ring by a thread, the screw ring and the slide pin are slidably connected, the outer side of the slide rod is slidably connected to a slide sleeve, the surface of the slide rod is fixedly connected to a guide pin, the guide pin and the slide sleeve are slidably connected, a spring is provided inside the slide sleeve, the lower end of the slide sleeve is fixedly connected to a wheel seat, and a pressure wheel is provided inside the wheel seat. By rotating the screw ring and the slide cylinder to make a threaded motion, the slide rod can be extended and retracted in the slide cylinder, and the spring can elastically move the slide sleeve downward, so that the pressure wheel tensions and stretches the yarn, so that the yarn is immersed in the water of the water tank and is stretched and thinned. At the same time, the water-soaked yarn makes the fine hairs in the yarn twist more tightly, making the yarn less likely to break.
