The auger is fixedly connected to the output shaft of the drive motor. The feed pipe 11 and the discharge pipe 12 are respectively close to different ends of the casing 10. The material is squeezed toward the discharge pipe 12 by the auger to cooperate with the granulation plate to form tablet particles of fixed shape. The auger is an existing well-known technology, which is not shown in the figure and will not be described here.

The guide body 30 forms a rectangular slot with a concave cross-section, and the side wall of the guide body 30 is fixedly connected to the casing 10, and the guide plate 31 forms a rectangular plate structure. A plurality of identical guide plates 31 are fixedly installed on the inner walls of both sides of the guide body 30, and the length of the guide plate 31 is less than the width of the cavity of the guide body 30, and the guide plates 31 are symmetrically positioned. The two guide plates 31 are arranged in an "eight" shape, and the guide plates 31 penetrate the material guide body 30 and the bottom box 32 and extend into the cavity of the bottom box 32. A socket is provided on the wall of the guide plate 31, and a thermocouple 33 is inserted into the socket. In this solution, by connecting the thermocouple 33 to a power source, the thermocouple 33 is energized to generate heat, and the heat is conducted through the guide plates 31. The multiple guide plates 31 separate the material guide slots of the material guide body 30 to form a serpentine curved channel. The material continuously rolls and is heated and dried in the curved channel. The heating time and heating area of the particles are increased by the guide plates 31. The particles are pre-dried during the discharge process, which can reduce the initial velocity of the particles sliding off the material guide body 30 and improve the dryness of the particles, thereby reducing the probability of the particles being damaged due to high velocity and excessive humidity when being discharged from the material guide body 30, thereby ensuring the quality and integrity of the particles after forming.

[0032] like Figure 2 and Figure 3 As shown, the cutting structure is arranged at the bottom of the discharge pipe 12 for cutting the formed particles. The cutting structure includes a cutting plate 20 and a driving motor 22. The driving motor 22 is fixedly installed at the bottom of the guide body 30. The output shaft of the driving motor 22 passes through the guide body 30 and is fixedly connected to the cutting plate 20.

The side groove 21 faces the same column of granulation holes of the granulation plate, so it can cut the material discharged from the same column of granulation holes, reduce the granulation error caused by time difference, and improve the quality of granulation.
[0033] The working principle of the utility model is as follows: the driving motor 22 drives the cutting plate 20 to rotate, and the part facing the side groove 21 is the cutting part, so that the cutting plate 20 can partially cover the granulation plate to ensure the pressure of material granulation. The cutting plate 20 with the side groove 21 can perform regional cutting on the granulation plate. The side groove 21 faces the same row of granulation holes of the granulation plate, so it can cut the materials discharged from the same row of granulation holes, reduce the granulation error caused by the time difference, and improve the quality of granulation.
[0034] The thermocouple 33 is connected to a power source. The thermocouple 33 is powered on to generate heat, and the heat is conducted through the guide plate 31. The multiple guide plates 31 separate the guide slots of the guide body 30 to form a serpentine curved channel. The material continuously rolls and is heated and dried in the curved channel.
