[0034] A pressure roller 13 is also arranged on the right side of the wire guide 3. An ultrasonic sensor is arranged inside the middle position of the pressure roller 13. A control board is arranged at one end of the wire guide 3 far from the winding machine.

[0035] The telescopic operating platform 4 is equipped with a weight sensor to detect the weight of the yarn bobbin. A weight set value is set on the control panel. When the weight of the yarn bobbin reaches the set value, the wire cutter 14 performs wire cutting operation to achieve automatic wire cutting with fixed weight.

[0036] The tension guide pulley 2 can move on the winding machine and stably guides the tow to the yarn bobbin 10 by adjusting to a suitable position.

[0037] The wire cutter 14 set on the yarn guide 3 of the winding machine is a swinging nozzle for automatic wire cutting. This wire cutter performs automatic wire cutting with fixed weight, automatically cuts wire according to the set winding weight, and the round-trip length is ≤ 0.9 m.

[0038] The wire take-up frame is equipped with a large-diameter yarn bobbin 10 with a pipe diameter of 0.6 m, achieving great stability of the yarn bobbin 10 and reducing the variability of the width of the carbon fiber roving.

[0039] The support 9 of the wire take-up frame adopts a strong steel frame, which can not only bear 1 ton of carbon fiber roving, but also protect the carbon fiber roving during transportation and storage. The above tension guide pulley 2 is of model CR1001 - B03 (99 porcelain rings); the wire cutter 14 is of model XC - C10 and is equipped with the function of automatic wire cutting with fixed weight; the weight sensor is of model YZC - 219; the ultrasonic sensor is of model UBS500 - GM18N; the support material of the wire take-up frame is Q235 - B carbon steel; the yarn bobbin material is UPVC. The control panel 7 is a touch screen PLC integrated controller, and the control panel of the winding machine is also a touch screen PLC integrated controller; it controls the rotation of the drive shaft, speed, monitors the weight of the wire take-up frame, gives an overweight alarm, and moves the casters. The drive shaft 8 is a GCr15 high-carbon chromium bearing steel drive shaft. The bearing 11 is a GCr15 high-carbon chromium bearing steel bearing, and the yarn bobbin material is UPVC yarn bobbin.

[0040] The drive shaft 8 is made of high-carbon chromium bearing steel, fixed on the drive box 1 of the winding machine, docks with the bearing 11 of the independent wire take-up frame yarn bobbin 10, drives the yarn bobbin 10 to wind, and sets the winding speed through the control panel 7. The winding speed is ≤ 600 m / min, and the unwinding speed is ≤ 20 m / min. The bottom of the winding machine is equipped with a telescopic operating platform 4. The wire take-up frame is placed on the platform 4 and can be telescoped through the electric casters 5 to dock with the drive shaft 8 on the winding machine. The maximum diameter that the entire winding device can reach is 4.8 m ( Figure 2 ) and the minimum diameter is 3.4 m ( Figure 3 ) The design of this telescopic platform 4 facilitates the transportation of the wire take-up frame and the precise docking of the bearing 11 of the yarn bobbin 10 and the drive shaft 8. Figure 1)。The bottom of the winding machine is also equipped with a weight sensor, which can display the weight of the raw wire in real time through the control panel 7. The wire guide 3 is set on the slide rail 6 and can move freely. The wire guide 3 is equipped with an automatic wire cutter, and the round-trip length is ≤0.9m for precise staggered winding. When the weight reaches the set range, the system will prompt through the alarm 12 and perform automatic wire cutting. The wire guide 3 is equipped with an automatic calibration pressure roller 13, which can automatically adjust the distance between the pressure roller 13 and the yarn spindle 10 to make the surface of the yarn spindle 10 smooth and achieve good winding efficiency.

[0041] As Figure 5 Shown are the front view and side view of the wire take-up frame, including the bracket 9, the yarn spindle 10, and the yarn spindle bearing 11. The diameter of the tube of the yarn spindle 10 is 0.6m. Using a large-diameter yarn spindle 10 can provide great stability for the yarn spindle 10 and reduce the variability of the width of the carbon fiber raw wire. When operating, the maximum diameter that the yarn spindle 10 can take up the wire is 1.5m. The core of the yarn spindle 10 is equipped with a bearing 11, and the driving shaft 8 on the winding machine provides power to drive the bearing 11 of the yarn spindle 10 for winding. The bearing 11 of the yarn spindle 10 is made of high-carbon chromium bearing steel, which is wear-resistant and has high contact fatigue strength. The overall size of the wire take-up frame is set as length × width × height: 1.5m × 1.7m × 1.8m. The wire take-up frame uses a strong steel bracket 9, which can not only bear a weight of 1 ton, but also protect the carbon fiber raw wire during transportation and storage. After the winding is completed, use a forklift to transport the wire take-up frame to the designated location. After adopting the above technical solution, the large-axis heavy winding device can wind high-quality raw wire weighing up to 1 ton, reduce the downtime during the carbon fiber production process, can improve the production efficiency by 90%, and reduce the labor cost.

[0042] When the device of the present utility model is in the working state, the pressure roller 13 should lean on the yarn spindle 10, aiming to make the surface of the collected raw wire flat and smooth and the appearance neat.

[0043] The wire guide 3 is equipped with an ultrasonic sensor to detect the distance between the pressure roller 13 and the yarn spindle 10. In the working state, the distance between the pressure roller 13 and the yarn spindle 10 should be zero. When the ultrasonic sensor detects a distance difference between the pressure roller 13 and the yarn spindle 10, the wire guide 3 will move on the slide rail 6 towards the yarn spindle 10 until it stops moving when the detected distance between the pressure roller 13 and the yarn spindle 10 is zero. A wire cutter 14 is arranged above the left of the pressure roller 13, and the wire cutter 14 swings back and forth on the wire guide 3. When the weight sensor senses that the weight of the yarn spindle 10 reaches the set value, the wire cutter 14 performs wire cutting. The control board of the wire guide 3: sets the automatic / manual movement mode of the wire guide, the back-and-forth swing of the wire cutter, and the wire cutting operation. Its advantages: reduce manpower and lower the production cost of products.

[0044] One complete working process: Control the casters 5 on the control panel 7 to push out the support platform 4. When the support platform 4 is completely pushed out, use a forklift to place the wire take-up frame at the designated position on the winding machine support platform 4, and keep the drive shaft 8 and the bearing 11 on the same horizontal line. Then control the casters 5 on the control panel 7 to retract the support platform 4, at which time the drive shaft 8 and the bearing 11 are butted against each other. Turn on the rotation of the drive shaft 8 on the control panel 7, and the drive shaft 8 of the winding machine drives the bearing 11 of the wire take-up frame to start rotating counterclockwise. The rotation speed can be adjusted on the control panel 7. Pass a bundle of raw filaments from above the winding machine in sequence from top to bottom around three tension guide wheels 2 (such as Figure 1 , 4 ), pass through the wire cutter 14, and then wind counterclockwise from below the yarn bobbin 10 to above the yarn bobbin 10. At this time, release the raw filament, and the raw filament will be wound counterclockwise on the yarn bobbin 10. Turn on the control board switch of the wire guide 3, and set the automatic calibration pressure roller mode, the fixed-weight wire cutting mode, and the automatic wire cutter swing mode. At this time, the ultrasonic sensor in the wire guide detects the distance between the pressure roller 13 and the yarn bobbin 10. When there is a distance difference between the pressure roller 13 and the yarn bobbin 10, the wire guide 3 will automatically move towards the yarn bobbin 10 on the slide rail 6 until the ultrasonic sensor detects that the distance between the pressure roller 13 and the yarn bobbin 10 is zero and then stops. During the winding process, as the raw filament continuously increases, the diameter of the yarn bobbin 10 also becomes larger and larger, and the yarn bobbin 10 will push the wire guide 3 to move and adjust in the slide rail 6. Set the weight setting value on the control panel 7. The weight sensor carried by the support platform 4 monitors the weight of the yarn bobbin 10. When the weight of the yarn bobbin reaches the weight setting value, the wire cutter 14 of the wire guide 3 cuts the wire. At this time, the alarm 12 will be turned on to prompt the operator. When the wire cutter 14 finishes cutting the wire, stop the rotation of the drive shaft 8. After it completely stops, the casters 5 push out the support platform 4. When the support platform 4 is completely pushed out, use a forklift to move the wire take-up frame away from the support platform 4; at this time, one winding work is completed.
