Embodiment 1

[0048] Step 1. Adjust the temperature of the test room to 25°C ± 2°C and the relative humidity to 50% ± 10%. Open all the sliding doors of the test chamber 1 and let it stand in this environment for more than 2 hours.

[0049] Step 2. Select a carbon fiber that needs to be dipped from the HF10-12K-A2 carbon fiber. The fixed length of the fiber is about 1500 meters, and it also needs to be in an environment with a temperature of 25°C±2°C and a relative humidity of 50%±10%. Leave in for more than 2 hours.

[0050] Step 3. Take the fiber ingot in step 2 and fix it on the unwinding mechanism 2 to ensure that the fiber is pulled out from the upper end.

[0051] Step 4. After pulling out the fiber, it passes through the porcelain eye 3, the transmission roller 4, the first spreading roller 4, and the second spreading roller 6. °, then pass between the extruding rubber roller one 10 and the extruding rubber roller two 11, and it is fixed on the cross bar of the receiving frame 13 wi...

Embodiment 2

[0057] Step 1. Adjust the temperature of the test room to 25°C ± 2°C and the relative humidity to 50% ± 10%. Open all the sliding doors of the test chamber 1 and let it stand in this environment for more than 2 hours.

[0058] Step 2. Select 1 ingot of carbon fiber that needs to be dipped from T700SC-12K-50C carbon fiber. The fixed length of the fiber is about 1700 meters. Leave in for more than 2 hours.

[0059] Step 3. Take the fiber ingot in step 2 and fix it on the unwinding mechanism 2 to ensure that the fiber is pulled out from the upper end.

[0060] Step 4. After pulling out the fibers, they pass through the porcelain eye 3, the transmission roller 4, the first spreading roller 4, and the second spreading roller 6. °, then pass between the extruding rubber roller one 10 and the extruding rubber roller two 11, and it is fixed on the cross bar of the receiving frame 13 with the positioning clip 15.
