[0027] Example

[0028] Please refer to Figure 1-3 As shown, the utility model provides a sizing device for the production and processing of industrial glass fiber cloth, including a sizing chamber 11, grooves are provided on the surfaces of both sides of the sizing chamber 11, a calendering assembly is provided on the inner side of the sizing chamber 11, and the calendering assembly is composed of an extrusion roller 19, a connecting block 24 and a hydraulic rod 29, wherein the extrusion roller 19 is arranged on the inner side of the coating chamber, and the connecting blocks 24 are connected to both sides of the extrusion roller 19. The top surfaces of the two connecting blocks 24 are fixedly connected to the telescopic ends of the hydraulic rods 29, and the hydraulic rods 29 are arranged on the inner side of the slots, so that by starting the two hydraulic rods 29, the two hydraulic rods 29 can drive the connecting blocks 24 to move, and the two connecting blocks 24 can drive the calendering rollers to move. The interior of the slurry coating chamber 11 is provided with an inclined surface 23, and the inclined surface 23 is arranged directly below the calendering roller, so that the calendering roller can be driven to move downward, thereby reducing the distance between the calendering roller and the inclined surface 23. When in use, after the sizing of the glass fiber cloth is completed, the glass fibers can be arranged on the surface of the inclined surface 23. When the glass fiber cloth is pulled by external equipment, the glass fiber cloth can be moved on the inclined surface 23. At this time, the glass fiber cloth can be pressed by the calendering roller to press out the excess slurry adsorbed inside the glass fiber cloth, and the pressed slurry can slide into the slurry coating chamber 11 through the inclined surface 23, thereby preventing the waste of coating and ensuring To improve the uniformity of the coating on the glass fiber cloth, a UV curing lamp 20 is provided on the inner side of the coating chamber 11, and the UV curing lamp 20 is arranged on one side of the calendering roller, so that when the calendering roller presses out the coating inside the glass fiber cloth, the coating on the surface of the glass fiber cloth can be quickly cured by the UV curing lamp 20, which increases the practicality of the device. The UV curing lamp 20 of the device is a prior art, and its principle is to use the energy generated by ultraviolet rays to excite the active substance in the curing agent, so that it reacts with the initiator in the coating, thereby realizing the rapid curing of the coating.
