[0016] The utility model is carried out in detail below combining with the drawing and specific embodiment. The embodiment is implemented with the utility model technical scheme as the premise, gives detailed implementation mode and specific operation process, but the protection scope of the utility model is not limited to the following examples.

[0017] Reference Figure 1 、 2 As shown in the utility model discloses a one -time desizing device for electronic grade glass fiber cloth, including pivot 1, pivot support 2 of the shaft, electronic grade glass fiber cloth 3, chuck 4, pre -desizing pool 5, lifting frame 6, pivot 1 is the cylinder, and the both ends of pivot 1 are equipped with a plurality of pivot supports 2, and the pivot support 2 of the both ends of pivot 1 is two two symmetry setting along the center of pivot 1, in the embodiment, the one end of pivot 1 is equipped with 2 pivot supports 2, and the pivot support 2 of the same end is symmetry setting along the center of pivot 1, and the one end of pivot support 2 away from pivot 1 is connected with the both ends of chuck 4, and chuck 4 is the cylinder, and the outside of chuck 4 is equipped with electronic grade glass fiber cloth 3.

[0018] Reference Figure 3、 4 As shown in the figure, the pre-desizing tank 5 is provided with a lifting frame 6, when the lifting frame 6 is lifted, the electronic grade glass fiber cloth 3 on any side of the rotating shaft 1 is in the pre-desizing tank 5 and below the liquid level of the pre-desizing solvent in the pre-desizing tank 5;

[0019] The working principle and beneficial effects are as follows:

[0020] When the electronic grade glass fiber cloth 3 is desized for the first time, the staff places the electronic grade glass fiber cloth 3 on the rotating shaft support 2 through the crane, and fixes it through the chuck 4. The rotating shaft support 2 is one standby one. When the desizing of the last bundle of electronic grade glass fiber cloth 3 for the first time is completed, the staff rotates the rotating shaft support 2 through the button, so as to desize the next bundle of electronic grade glass fiber cloth 3 for the first time. By increasing a pre-desizing tank 5 and a lifting frame 6, the electronic grade glass fiber cloth 3 is pre-desized in the pre-desizing solvent. The main components of the pre-desizing solvent are pure water and sodium hydroxide solution, which is heated to 90 DEG C. After the staff places the electronic grade glass fiber cloth 3 on the rotating shaft support 2, the pre-desizing tank 5 is lifted electrically until the electronic grade glass fiber cloth 3 is soaked in the pre-desizing solvent. After 30 minutes, the lifting frame 6 will automatically fall to dry the soaked electronic grade glass fiber cloth 3. After the production of the last bundle of electronic grade glass fiber cloth 3 is completed, the rotating shaft 1 is rotated, so as to produce;

[0021] By improving the design of the first desizing equipment, the electronic grade glass fiber cloth 3 is soaked in the pre-desizing tank 5 for pre-desizing before the first desizing. The sizing material is easily dissolved when meeting the hot pre-desizing solvent, which ensures the toughness and good after-opening performance of the electronic grade glass fiber cloth 3. After pre-desizing, the sizing material is mainly left in the pre-desizing solvent, which plays a role in environmental protection. After the pre-desizing solvent evaporates, the sizing material will be extracted again. The extracted sizing material can be mixed with the normal sizing material in a certain proportion, so as to be reused, which greatly saves the cost.
