When adding materials to the disperser for mixing, start motor A to drive the rotating seat to rotate, and the rotating seat can drive the three limit frames to rotate around the internal position of the disperser, and the mixing claws outside the mixing belt mix the materials inside the disperser;

[0017] 03. After the materials inside the disperser are mixed, the mixed raw materials are pumped into the reserve barrel through the cooperation of metering pump B and the delivery pipe. During this period, the filter screen filters and screens the raw materials entering the metering pump B to prevent the raw materials with larger particles from being delivered to the inner position of the reserve barrel.

[0021] 1. When adding materials to the disperser for mixing, start motor A to drive the rotating seat to rotate, and the rotating seat can drive the three limit frames to rotate around the internal position of the disperser, and the mixing claws outside the mixing belt mix the materials inside the disperser.

[0022] 2. After the materials inside the disperser are mixed, the mixed raw materials are pumped into the reserve barrel through the cooperation of metering pump B and the delivery pipe. During this period, the filter screens the raw materials entering the metering pump B to prevent larger particles from being delivered to the inner position of the reserve barrel. When there are many large particles of raw materials at the lower end of metering pump B, the raw materials that have not passed through the lower end of metering pump B can be returned to the inner position of the disperser through the return pump for further full mixing. At the same time, the blockage of the delivery position of metering pump B can be avoided.

[0023] 3. The material inside the reserve barrel is transported to the impregnator through a pipeline, immersed in the impregnation area inside the impregnator for two seconds and then transferred to the upper position of the conveyor belt for backward transportation. During the use of the conveyor belt, the material attached to the upper end of the conveyor belt is scraped out to the inside of the collecting tank through the cooperation of the scraper, so as to facilitate the collection of materials and trace them back to the impregnation area of ​​the impregnator.

[0024] 4. After the finished product is led out by the conveyor belt, it is led to the middle position between the gear of the steam rotary rod and the guide rotary rod. Starting the guide motor drives the guide rotary rod to rotate. Through the meshing transmission of the gear of the steam rotary rod and the gear of the guide rotary rod, the material in the middle position is clamped and moved backward for delivery.

[0025] 5. Motor B drives the active bevel gear to rotate, and the active bevel gear meshes with the gear ring, and the gear ring drives the three auxiliary bevel gears to rotate. Since the internal upper end rotating rod of the limit frame is fixedly connected to the auxiliary bevel gears, the three mixing belts will be driven to rotate at the outer position of the limit frame during the rotation of the auxiliary bevel gear. The mixing claws set on the mixing belts will mix and overturn the materials inside the disperser in the upper and lower positions, thereby improving the mixing efficiency of the materials inside the disperser during mixing.

[0026] 6. Waste water will be generated when the impregnation area of ​​the impregnation machine is cleaned. The clean waste water of the impregnation machine will be transferred to the internal position of the collection tank, and the waste water will be transferred to the internal position of the storage tank through the cooperation of the supply pipe and the delivery pipe. After starting the drying cylinder heater, the delivery pipe will transfer the waste water inside the storage tank to the drying cylinder heater for use. The drying cylinder heater heats the waste water to 120°C and transmits it neatly to the internal position of the steam rotary rod. In the process of transferring the steam rotary rod to fit the material, the material is subjected to indirect steam heating and rolling drying, and the waste water is further utilized to quickly set the shape and prevent stickiness.
