Description

Technical Field

[0001] This utility model belongs to the field of power equipment manufacturing technology and relates to a vacuum impregnated yarn rod winding device. Background Technology

[0002] Vacuum impregnation and yarn winding is a crucial step in the manufacturing of power equipment (such as transformers, insulating bushings, and high-voltage reactors). Its core objective is to produce composite insulating materials with excellent insulation, mechanical strength, and resistance to environmental aging through high-precision yarn winding and vacuum impregnation curing technology. Yarn winding refers to uniformly winding glass fiber yarn (or other high-performance fibers) onto the surface of a mandrel (yarn rod) at a specific linear density, angle, and number of layers to form an insulating skeleton. Vacuum impregnation involves placing the wound yarn rod in a vacuum environment, impregnating it with epoxy resin or other insulating adhesive, and using vacuum negative pressure to allow the adhesive to fully penetrate the fiber gaps, subsequently curing to form a dense insulator.

[0003] In existing technologies, during yarn winding, operators typically find a suitable roller based on the required size, tie one end of the glass yarn to a fixed-length roller, and manually rotate the roller handle according to the required number of strands, counting the rotations manually. After the required number of rotations, the glass fiber is cut off with scissors. This method is not only inefficient but also prone to human error. Furthermore, traditional winding mechanisms usually require frequent manual adjustments to glass yarn and rollers of different lengths. Too many roller specifications result in a large footprint; counting and length determination rely entirely on operators, leading to inconsistent product quality and high labor intensity. Adding new lengths of glass fiber requires new rollers, which lack compatibility and scalability. The winding mechanism also suffers from slow diameter adjustment, long specification switching time, low winding speed, and large fluctuations in linear density, making it difficult to meet the high-efficiency and precision requirements of modern textile production. Utility Model Content

[0004] The purpose of this invention is to solve the technical problems of low yarn winding efficiency, high labor intensity, and difficulty in ensuring specification compatibility in the existing technology, and to provide a vacuum impregnated yarn rod winding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] In a first aspect, the present invention discloses a vacuum impregnated yarn winding device, comprising a winding device movably connected to a support frame, wherein the winding device is provided with a diameter adjustment device; the winding device includes a gear connected to a motor, the gear meshing with a toothed disc; the diameter adjustment device includes a plurality of sliders slidably disposed on the toothed disc for supporting glass fibers; each slider is equidistant from the center of the toothed disc, and each slider is connected to a power device for adjusting the distance between the slider and the center of the toothed disc; both the motor and the power device are connected to a control device.

[0007] Further improvements are made in the following aspects:

[0008] The gear disk is provided with several slide rails corresponding to the slider, and the slider is slidably mounted on the slide rails; the slider is also connected to a support rod, and each support rod is connected to a support rod fixing block. The support rod fixing block is slidably connected to a track, one end of which is supported on a support frame and the other end is located at the center of the gear disk shaft; the support rod fixing block is connected to a power device, which is used to drive the support rod fixing block to move on the track, and then drive the slider to move on the slide rail to adjust the diameter through the support rod.

[0009] The power unit is a telescopic cylinder, which is connected to an electric cylinder.

[0010] Several sliders are evenly arranged on the gear disk.

[0011] The number of sliders is even.

[0012] The power unit is equipped with a photoelectric sensor to detect the distance between the slider and the center of the gear disk and transmit it to the control device.

[0013] The power unit is equipped with a mechanical limit switch.

[0014] The slider is equipped with a tension sensor and a PID controller, which are used to detect the real-time tension of the yarn and transmit it to the control device to adjust the torque of the motor to control the yarn density.

[0015] The control device is equipped with a human-machine interface and supports several preset specifications, including diameter, number of revolutions and motor speed.

[0016] An automatic cutting device is provided on one radial side of the toothed disc. The automatic cutting device includes a fixed slider fixed on the support frame. The fixed slider is parallel to the slider axis. A glass yarn storage box is provided on the other side of the fixed slider.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This utility model discloses a vacuum-impregnated yarn winding device. It relies on gears to drive a geared disc, which is connected to a motor. The diameter, number of turns, and rotation speed of the winding device are all adjustable. The starting position of the winding and the cutting position are aligned on the same diameter line, facilitating cutting and handling by the operator. The diameter adjustment device, through a power unit, allows for adjustment of the radius of the slider on the geared disc, regulating the winding diameter range of the glass fiber. Its coaxial design with the turntable spindle ensures uniform yarn tension during winding. This invention solves the technical problems of traditional winding mechanisms, which typically require frequent manual adjustments of glass yarn and rollers of different lengths. The rollers have too many specifications, occupying a large area; adding new specifications of glass fiber requires new rollers, resulting in poor roller compatibility and lack of scalability; slow diameter adjustment speed; long specification switching time; low winding speed; and large fluctuations in linear density, making it difficult to meet the high-efficiency and precision requirements of modern textile production.

[0019] Furthermore, a dual positioning system using photoelectric sensors and mechanical limit switches is employed. After the diameter adjustment is completed, a positioning signal is triggered, with an error range of ≤±0.1mm.

[0020] Furthermore, by integrating a tension sensor and a PID controller, the torque of the servo motor is dynamically adjusted according to the yarn tension, and the linear density fluctuation is controlled within ±2.5%.

[0021] Furthermore, the human-machine interface supports preset parameters for 5 specifications (diameter, number of revolutions, and rotation speed) and allows for one-click switching of production modes. Attached Figure Description

[0034] See Figure 1 , Figure 2 and Figure 3 This utility model discloses a vacuum impregnated yarn winding device, including a winding device 1 movably connected to a support frame, and a diameter adjustment device 3 provided on the winding device 1; the winding device 1 includes a gear connected to a motor, the gear meshing with a toothed disc; the diameter adjustment device 3 includes a plurality of sliders 31 slidably disposed on the toothed disc for supporting glass fibers; for example, 4, 6, or 8 sliders 31 are evenly disposed on the toothed disc; each slider 31 is equidistant from the center of the toothed disc, and each slider 31 is connected to a power device for adjusting the distance between the slider 31 and the center of the toothed disc; both the motor and the power device are connected to a control device 2. The control device 2 is provided with a human-machine interface, supporting several preset specification parameters, including diameter, number of turns, and motor speed. An automatic cutting device is provided on one radial side of the toothed disc, the automatic cutting device including a fixed slider fixed on the support frame, the fixed slider being parallel to the axis of slider 31; a glass fiber storage box 4 is provided on the other side of the fixed slider.

[0035] The gear disk is provided with several slide rails 32 corresponding to the slider 31, and the slider 31 is slidably mounted on the slide rails 32. The slider 31 is also connected to a support rod 33, and each support rod 33 is connected to a support rod fixing block. The support rod fixing block is slidably connected to a track 34, one end of which is supported on a support frame and the other end is located at the center of the gear disk shaft. The support rod fixing block is connected to a telescopic cylinder 35, and the telescopic cylinder 35 is connected to an electric cylinder 36. The electric cylinder pushes and pulls the telescopic rod to a certain angle to drive the support rod fixing block to move on the track 34, and then drives the slider 31 to move on the slide rail 32 through the support rod 33, adjusting the diameter range of the glass fiber winding. The design is coaxial with the turntable main shaft to ensure uniform yarn tension during the winding process. This utility model significantly improves production efficiency. This solution, through an automatic diameter adjustment mechanism and a screw and nut transmission assembly, achieves diameter adjustment within 30 seconds and shortens the specification switching time to 90 seconds, greatly improving efficiency.

[0037] The slider 31 is equipped with a tension sensor and a PID controller to detect the real-time tension of the yarn and transmit it to the control device 2, adjusting the motor torque to control the yarn density. By integrating the tension sensor and PID controller, the servo motor torque is dynamically adjusted according to the yarn tension, keeping the linear density fluctuation within ±2.5%.

[0038] The working process of this utility model is as follows:

[0039] (1) The operator inputs the winding diameter and number of turns on the control panel;

[0040] (2) Clamp the glass fiber onto the winding mechanism;
