[0015] Further, the preparation process of the ultra-thin vulcanized fiber paperboard for high-performance insulation is characterized in that: 1. Raw material preparation: select appropriate fiber raw materials and perform necessary pretreatment to ensure that the raw materials meet the requirements of subsequent processing.

[0016] 2. Pulping treatment: add the prepared fiber raw materials into the pulping tank body, start the processing drive motor, drive the fixed square shaft to rotate through the meshing transmission of the driving gear and the driven gear, and then drive the drive shaft and the pulping impeller to rotate, so as to preliminarily disintegrate the materials in the tank. For low-concentration pulping, only the processing drive motor needs to be started to realize pulping operation.

[0017] 3. Pulping switching: if higher-concentration pulping treatment is needed, the fixed pressing plate can be pressed down to make the extrusion protrusion rotate and extrude the sliding switching plug rod downward, so that the sliding switching plug rod is inserted into the switching slot, the fixed square shaft is pushed into the inner side of the connecting slot, and the driven gear is disengaged from the driving gear. At this time, when the processing drive motor is started again, it will drive the drive shaft to rotate directly through the cooperation of the fixed driving gear and the connecting gear, and further rub and extrude the materials through the processing connecting rotating shaft and the spiral roller, so as to achieve the purpose of fiber bundle separation.

[0018] 4. Self-adaptive protection: throughout the process, if the liquid level in the pulper is too high, the fixed floating plate will rise due to buoyancy, and the material protection baffle will slide up to prevent material from splashing out during equipment operation.

[0019] The application provides a high-performance ultra-thin vulcanized fiber paperboard preparation device and process for insulation, which has the following beneficial effects: The application realizes the splash-proof function in the material processing process through the setting of the protection mechanism. When the liquid level in the pulper rises to a certain height, the fixed floating plate will float up due to the buoyancy, and then drive the material protection baffle connected thereto to slide up along the guide structure. At this time, the material that may splash during the operation of the equipment will be effectively blocked by the rising material protection baffle, preventing it from overflowing. This design not only maintains the cleanliness of the working environment, but also significantly reduces the cleaning burden and labor intensity of the operator, while helping to ensure the continuity and safety of production operations, thereby improving the overall work efficiency.

[0020] In addition, through the setting of the switching mechanism, the switching of the pulping structure is realized. When low-concentration pulping operation is performed, only the processing drive motor needs to be started, and the power is transmitted to the fixed square shaft through the meshing of the driving gear and the driven gear, and then the fixed square shaft and the driving shaft are connected through sliding to drive the pulping impeller to rotate, completing the regular pulping operation. When high-concentration pulping is needed, the fixed pressing plate can be pressed down to rotate and drive the extrusion protrusion to rotate synchronously. The rotating extrusion protrusion presses the sliding switching rod downward to make it inserted into the switching slot. At the same time, the sliding switching rod is inserted, the fixed square shaft is pushed downward to make its end embedded into the connection slot, and the driven gear is driven to slide downward to disengage from the meshing state with the driving gear. At this time, the power of the processing drive motor is transmitted to the driving shaft through the meshing of the fixed driving gear and the connection gear, and then transmitted to the driving shaft through the sliding connection of the fixed square shaft and the connection slot. The driving shaft is further driven to rotate the processing connection shaft and the spiral roller under the cooperative guidance of the sliding switching rod and the switching slot, and the material is subjected to strong rubbing and extrusion to realize the full separation and separation of the fiber bundle. This structure design cleverly realizes the switching of low-concentration and high-concentration pulping functions on the same equipment, without the need for additional special equipment, significantly reducing the procurement and maintenance cost of the equipment, saving the production site space, avoiding the downtime loss caused by frequent equipment replacement, and effectively improving the continuity and efficiency of production.

[0021] In addition, through the setting of the above-mentioned mechanism, not only the effective splash-proof in the processing process is realized, the operating environment is kept clean and safe, the labor intensity is reduced, the pulping mode is switched conveniently, the different process requirements are met, the repeated investment of multiple equipment is avoided, and the operation is simple, the cost is low, and the efficiency is high.
