[0035] As Figure 1 shown, this embodiment provides a desizing device for electronic-grade quartz fiber cloth, which includes a quartz desizing cylinder 1, a high-temperature furnace 2, a first track 3, a second track 4, and a heating component 5. Among them,

[0036] The top of the high-temperature furnace 2 is open, and the first track 3 and the second track 4 are symmetrically installed inside the high-temperature furnace 2 and extend from the bottom of the high-temperature furnace 2 to the top side of the high-temperature furnace 2;

[0038] The heating component 5 is arranged on the inner wall of the high-temperature furnace 2.

[0039] In the above technical solution, a quartz desizing cylinder 1 made of quartz material is used to wind the quartz fiber cloth into the high-temperature furnace 2 for desizing.

At the same time, the track and the quartz desizing cylinder 1 are used in cooperation, so that the quartz fiber cloth can quickly enter the high-temperature furnace 2 after winding is completed, so as to improve the desizing efficiency. Embodiment 2

[0040] A desizing device for electronic-grade quartz fiber cloth provided in this embodiment is different from the desizing device for electronic-grade quartz fiber cloth provided in Embodiment 1 in that:

[0050] To add a protective measure between the limiting plate 9 and the quartz fiber cloth to prevent the limiting plate 9 from damaging the quartz fiber cloth, a protective pad 12 is further included. The protective pad 12 is arranged on the side of the limiting plate 9 facing the quartz desizing cylinder 1. In this embodiment, the protective pad 12 is made of silica gel or sponge.

[0051] To further discharge the waste gas generated during the desizing process from the furnace to prevent the accumulation of harmful gases, an exhaust fan 13 is further included. The exhaust fan 13 is installed on the side top of the high-temperature furnace 2.

[0052] To accelerate the gas circulation in the high-temperature furnace 2 to ensure uniform distribution of the temperature in the furnace, improve the thermal efficiency, and help the slurry decompose and volatilize more evenly, a circulation fan 14 is further included. The circulation fan 14 is installed on the side of the high-temperature furnace 2.

[0053] In summary, the electronic-grade quartz fiber cloth desizing device provided in this embodiment, by adopting the cooperation mode of the threaded shaft 7 and the slider 6, enables the quartz desizing cylinder 1 to quickly enter the furnace for desizing after the quartz fiber cloth is wound on the top of the high-temperature furnace 2 by rotating the threaded shaft 7, and after the desizing is completed, the quartz desizing cylinder 1 can quickly rise to improve the desizing efficiency; by arranging a limiting component on the quartz desizing cylinder 1, the quartz fiber cloth wound on the desizing 1 can be limited to ensure the stability of the quartz fiber cloth during desizing; by arranging the exhaust fan 13 and the circulation fan 14, the air circulation in the furnace can be accelerated to help the desized slurry decompose and volatilize more evenly.

[0054] The above are only the preferred embodiments of the present invention.
