A connecting pipe 280 is provided at the bottom end of the piston cylinder 270, and a spray head 290 is connected to one side of the piston cylinder 270. The spray head 290 is connected to a preparation box 2910 fixedly connected to the top of the base 100. A plurality of heating blocks 2911 are installed at the top of the inner wall of the preparation box 2910. A second electric push rod 2920 is provided on the side of the top of the liquid storage tank 240 away from the first electric push rod 250. A vertical plate 2930 is connected to the movable end of the second electric push rod 2920. A round rod 2940 is welded to the side of the vertical plate 2930 away from the second electric push rod 2920. A push plate 2950 is fixedly connected to the side of the round rod 2940 away from the vertical plate 2930. A horizontal plate 2960 is welded to one side of the bottom end of the push plate 2950.

[0026] The raw materials are placed in the reactor 110 for processing reaction, the servo motor 210 is started, the stirring shaft 220 is driven to rotate, and the inside of the reactor 110 is stirred by the stirring shaft 220, so that the molding efficiency of the urotropine solution is enhanced. After the solution is prepared, it enters the liquid storage tank 240 through the guide tube 230, and the first electric push rod 250 is started to drive the piston rod 260 to squeeze the urotropine solution in the piston cylinder 270, so that the urotropine solution is sprayed out through the spray head 290.

[0033] When particles fall onto the surface of the screen 360 through the discharge chute 2961, the vertical plate 2930 moves, driving the rack 320 to move through the support rod 310, and the rack 320 drives the gear 330 to rotate. The gear 330 drives the spring telescopic rod 350 to rotate synchronously through the circular shaft 340. The spring telescopic rod 350 can knock on one side of the screen 360, so that the smaller diameter particles will fall into the storage box 2 3910 through the vibration of the screen 360, and the larger shells will fall into the inside of the storage box 1 390 through the vibration, thereby realizing the screening of the particles, which can effectively ensure the consistency of the product and thus improve the product quality.

[0034] When in use, by starting the first electric push rod 250, the urotropine solution is sprayed out through the spray head 290, and the sprayed solution will be in a mist state. The mist urotropine solution can be solidified into particles by the heating block 2911, thereby realizing the production of urotropine particles, effectively shortening the production cycle, making the production of urotropine faster, and thus improving the utilization rate of the device. After spraying, the second electric push rod 2920 moves the urotropine particles in the preparation box 2910 out of the discharge trough 2961 through the push plate 2950, ​​so as to facilitate better centralized processing and improve the work efficiency of the staff. In order to improve the working efficiency, when the particles fall into the surface of the screen 360 through the discharge chute 2961, the vertical plate 2930 moves and drives the rack 320 to move through the support rod 310, and the spring telescopic rod 350 can knock on one side of the screen 360, so that the smaller diameter particles will fall into the storage box 2 3910 through the vibration of the screen 360, and the larger shell will fall into the storage box 1 390 through the vibration, thereby realizing the screening of the particles, which can effectively ensure the consistency of the product and thus improve the product quality. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
