[0027] Specifically, the glass fiber raw materials may include the following components: pyrophyllite, limestone, kaolin, quartz sand, firefly powder, sodium sulfate, and soda ash.

[0028] like Figure 1-7 As shown, a reinforced composite glass fiber production system includes a cleaning box 1, a first wiping part 2, an impregnation box 3 and a second wiping part 4 which are arranged in sequence, the first wiping part 2 and the second wiping part 4 both include a support frame 5 and a wiping wheel, the wiping wheel is rotatably connected to the support frame 5, the glass fiber drawing 6 horizontally passes through the upper part of the wiping wheel, the first wiping part 2 also includes a heating plate 7, and the heating plate 7 is located at the lower part of the wiping wheel.

[0030] A heating plate 7 is provided at the lower part of the first wiping part 2, and a heating wire is built into the heating plate 7. The wiping wheel is heated and dried by the heating plate 7, so that the first wiping part 2 can be quickly restored to dryness.

[0031] Correspondingly, a drying component may be provided between the first wiping part 2 and the wetting box 3 and after the second wiping part 4 to further dry the drawn glass fibers 6 .

[0032] like Figure 3 As shown, the wiping wheel includes a circular wiping block 8 and two clamping plates 9 located outside the wiping block 8.

The clamping plate 9 and the wiping block 8 are coaxially arranged. The outer ring of the wiping block 8 is provided with a connecting groove 11, and the glass fiber drawing 6 runs through the connecting groove 11.

[0033] The connecting groove 11 is annular, and when the wiping wheel rotates, the glass fiber drawing 6 can be wiped dry by the wiping block 8, and the two clamping disks 9 are fixedly connected. In order to reduce the weight of the wiping wheel, the clamping disk 9 can be made of hollow material, and the depth of the connecting groove 11 is sufficient to accommodate the glass fiber drawing 6 and the heating plate 7.

[0034] like Figure 3 As shown, the lower part of the support frame 5 is connected to two squeezing rollers 12, and the two squeezing rollers 12 are respectively located on both sides of the wiping wheel.

[0035] The squeezing roller 12 is used to squeeze the wiping wheel to remove the excess liquid in the wiping block 8. To cooperate with this function, a material box can be provided on the lower side of the wiping wheel to recycle the excess liquid.

[0043] When the wiping block 8 rotates, it can absorb the excess liquid on the surface of the glass fiber drawing 6 and remove dust, fibers, etc. on the surface of the glass fiber, so that the surface of the glass fiber drawing 6 remains clean.

[0044] Directions: When the device is used, the glass fiber drawing 6 is cleaned by passing through the cleaning box 1, and then the cleaned glass fiber drawing 6 is wiped and dried by the first wiping part 2; The wiping block 8 of the first wiping part 2 is squeezed by the squeezing roller 12 to squeeze out the excess water, and the wiping block 8 is heated and dried by the heating plate 7 at the same time; The dried glass fiber drawing 6 enters the impregnation box 3 for impregnation, and after impregnation, enters the second wiping part 4. The second wiping part 4 wipes the excess impregnation liquid and evenly applies the impregnation liquid to the outside of the glass fiber drawing 6, so that the coating on the outside of the glass fiber drawing 6 is uniform.
