With the fine adjustment of the micro electromagnetic telescopic guide rod 1293, the dry ice particle linear mesh injection end 1290 will form a mesh on the PVC particle discharge path. The dry ice particles are evenly distributed in the mist, so that the dry ice particles quickly sublimate when contacting the high-temperature PVC particles, absorb heat, and effectively reduce the material temperature. At the same time, local overcooling or hot spots are avoided, ensuring uniform cooling and surface quality of the discharged material. In addition, during the operation, the angle sensor 121 and the position sensor connector 127 are used to continuously monitor the working state and injection position of the transmission component, and the information is fed back to the external sequential logic controller, so that the external sequential logic controller can adjust the injection angle, speed and total amount in real time according to the set optimal cooling strategy to adapt to different discharge conditions and production requirements, so as to keep the entire cooling process optimized. At the same time, when the above-mentioned dynamic uniform cooling component 12 is in operation, it can adjust the injection angle, speed and total amount according to the horizontal linear track 10 and the vertical linear track 1 The two-dimensional angle adjustment formed by 1 is convenient for all-round cleaning of the material adhesion generated in the subsequent uniform cooling component 13 and the discharge box 2. Then, the control motor 136 is activated, and the superconducting magnet alloy receiving plate 131 is driven through the meshing action of the transmission gear 137 and the rack 138. Under the cooperation of the transmission clamping moving wheel frame 132, it is located outside the first adjustment arm frame 133 to move. Then, with the coordinated action of the first adjustment arm frame 133 and the second adjustment arm frame 134, the superconducting magnet alloy receiving plate 131 and the transmission clamping moving wheel frame 132 can move flexibly on the inner wall surface of the discharge box 2 to form a staggered stepped distribution, ensuring that each batch of PVC particles can evenly contact the cooling surface, and according to the discharge condition and temperature feedback,The overall device activates the pneumatic adjustment guide rod 135, and by adjusting the angle and position of the second adjustment arm 134, the superconducting magnet alloy receiving plate 131 can dynamically adjust the receiving angle according to the material falling speed, ensuring that the stability and efficiency of the cooling effect can be maintained even in the continuous production process. After that, the PVC hard particles that have been fully cooled by the above-mentioned uniform cooling component 13 gradually fall to the bottom of the discharge box 2, and are automatically measured and discharged through the weighing metering discharge end 14. When the accumulation of PVC particles reaches a preset threshold, the sensor on the photoelectric detection seat connecting frame 71 sends a signal, so that the electric guide rod 72 is started, and the start signal is received. After that, the electric guide rod 72 drives the rotating arc rod 73 to start rotating. During the rotation process, the first adjusting gear 74 and the second adjusting gear 75 rotate synchronously due to the connection with the rotating arc rod 73, thereby realizing the precise positioning control of the docking opening and closing plate 76. As the first adjusting gear 74 and the second adjusting gear 75 rotate, the docking opening and closing plate 76 slides along the inner wall of the side frame plate driven by the rotating arc rod 73. After reaching the predetermined position, the docking opening and closing plate 76 performs an opening or closing action to control the flow path of the PVC particles, thereby facilitating the instant opening and closing and precise metering control of the particle flow, thereby ensuring the weight consistency of each batch. At the same time, when the magnetic field generates a regulator 3, the superconducting magnet alloy receiving plate 131 can periodically change the magnetic field strength applied to the magnetic material in the superconducting magnet alloy receiving plate 131 during the process of receiving the material, thereby causing the surface temperature of the superconducting magnet alloy receiving plate 131 to change, thereby realizing the active regulation of the material cooling process, so that the periodic fluctuation of the temperature can more efficiently exchange heat energy with the material, ensure that the heat is quickly extracted, maintain the material temperature uniform and suitable for subsequent processing, and effectively improve the cooling efficiency as a whole, and also enhance the flexibility and precise control ability of the cooling process, and in the dry ice particle transfer device 6 and the external dry ice particle making device are equipped with In this way, the instant supply of dry ice particles provides a rapid cooling effect for the material, and the cooperation of the external dry ice particle maker and the appropriate dispenser ensures the continuous supply of dry ice, and can be dynamically adjusted according to actual needs to achieve high-efficiency heat absorption and material cooling. It can form multiple groups of discharge structures for dry ice particle supply to reduce operating costs. Then, with the cooperation of the countercurrent cooling heat exchanger 5, during the discharge process, through the connection with the bottom of the discharge box 2 and the semiconductor heat absorption structure 4, a closed-loop heat exchange system is formed, and the cooling rising gas and the heat absorption guide pipeline are used to improve the heat exchange efficiency and further enhance the cooling capacity of the material.
