[0022] In order to better understand the technical solution of the present utility model, the embodiments provided by the present utility model are described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-5 As shown, it can be understood that the present embodiment provides a granulator, characterized in that it includes: a granulator 1, a pelletizer 2 and a conveying channel 3; the granulator 1 includes an inlet 11, the pelletizer 2 includes a cavity 21, the inlet 11 is connected to the cavity 21, a cutter 22 is provided in the cavity 21 corresponding to the inlet 11, and a pelletizer outlet 211 is provided on the cavity 21; the pelletizer 2 includes a first fan 24, a first air inlet 212 is provided on the cavity 21, and the first fan 24 is connected to the first air inlet 212; the conveying channel 3 is connected to the pelletizer outlet 211, the pelletizer outlet 211 is arranged above the cutter 22, and the cutter 22 is arranged above the first air inlet 212.

[0024] In this embodiment, the particle outlet 211 is arranged above the cutter 22, and the cutter 22 is arranged above the first air inlet 212, so that the material cut into particles by the cutter can be quickly blown away from the material inlet 11 by the wind blown in by the first air inlet 212, thereby solving the problem that the sticky particles cannot quickly leave the material inlet 11 due to the existing left and right blowing, which leads to particle accumulation and wall hanging, and further leads to the need for continuous manual debugging, which increases costs and reduces production efficiency; in addition, the wind moving from bottom to top allows the particles to rotate in the cavity 21 when they are blown upward in the cavity 21, thereby increasing the time that the particles stay in the cavity 211 with a cooling effect, thereby improving the cooling effect of the particles, reducing the time and cost of subsequent cooling, reducing production costs, and improving production efficiency.

[0025] In this embodiment, the first air inlet 212 is preferably directed toward the material inlet 11 , so as to directly and quickly blow the produced particles away from the material inlet 11 , further solving the problem that sticky particles are not easy to escape from the material inlet 11 .

[0026] In this embodiment, the first air inlet 212 is preferably connected to the first fan 24 below the height of the cutter 22 to save materials; however, the first fan 24 can also be connected to the cavity 21 above the height of the cutter 22, and then connected to the first air inlet 212 below the cutter 22 through a closed pipe, and then blow wind toward the inlet 11, thereby cooling the cavity 21 at the same time.

[0027] In the second embodiment, an air duct 213 is provided in the cavity 21, and the first air inlet 212 is connected to the first end of the air duct 213. The first fan 24 blows the wind from the first air inlet 212 into the air duct, and the air duct 213 guides and transmits the wind to the inlet 11, and then uses the wind to drive the particles to be transported to the next processing position, thereby reducing the time the particles stay at the inlet 11 and reducing the probability of particle accumulation and wall hanging.

[0028] On the basis of the above embodiments, further, the air duct 213 is arranged at the bottom of the side of the cavity 21, which is conducive to transporting wind from the lower part to the upper part, and then using the wind to drive the particles to be transported to the next processing position.

[0029] On the basis of the above embodiments, the air duct 213 is further formed into a semicircular shape with the convex surface facing downward. The semicircular design first gathers the wind in the air duct, increases the wind force when the wind is guided and transmitted to the inlet 11 through the air duct 213, and thus improves production efficiency.

[0030] On the basis of the above embodiments, further, a first guide plate 2131 is provided on the air duct 213. The first guide plate 2131 changes the direction of the wind blown out from the first air inlet 212 from the horizontal direction to the obliquely upward direction and blows toward the inlet 11, blows the just-cut particles away from the inlet 11, and makes the particles blown away from the inlet 11 rotate in the cavity 211 under the action of the airflow, thereby increasing the time that the particles stay in the cavity 211 with a cooling effect, thereby improving the cooling effect of the particles, reducing the time and cost of subsequent cooling, reducing production costs, and improving production efficiency.

[0031] On the basis of the above embodiments, further, the pelletizing device 2 includes a second fan 23, a second air inlet 214 is provided on the cavity 21, the second fan 23 is connected to the second air inlet 214, and the second air inlet 214 is connected to the second end of the air duct 213. The design of the two fans can increase the power when the freshly cut particles are transported.

[0032] On the basis of the above embodiments, further, the first guide plate 2131 is fixed in the middle of the air duct 213, and the first guide plate 2131 includes two oblique plates connected to each other at the top; the lower contours of the two oblique plates are respectively fitted to the contour of the air duct 213, and the lower parts of the two oblique plates are fixed on the air duct 213. This technical solution allows the wind coming out of the first air inlet 212 and the second air inlet 214 to change from a horizontal direction to an oblique direction at the first guide plate 2131, and both winds blow toward the inlet 11, blowing the just-cut particles away from the inlet 11. In addition, the oblique meeting of the two winds will form two airflows with opposite rotation directions on both sides of the cutter 22, so that the particles blown away from the inlet 11 rotate in the cavity 211 under the action of the two airflows, thereby increasing the time of the particles in the cavity 211 with a cooling effect, thereby improving the cooling effect of the particles, reducing the time and cost of subsequent cooling, reducing production costs, and improving production efficiency.

[0033] On the basis of the above embodiments, further, the particle outlet 211 is arranged on the top surface of the cavity 21; a second guide plate 215 is arranged on the cavity 21, and the upper end of the second guide plate 215 is connected to the edge of the particle outlet 211, and the upper end of the second guide plate 215 is connected to the inner side of the cavity 21. The area of ​​the top surface of the cavity 211 is larger than the area of ​​the particle outlet 211. This technical solution prevents the cut particles from hanging on the non-particle outlet 211 position on the top surface of the cavity 211, preventing the wall from affecting the conveying of particles, improving the conveying efficiency, and reducing the failure rate.

[0034] On the basis of the above embodiments, further, the conveying channel 3 includes a mouth closer 31 and a pipe 32; the mouth closer 31 includes a first interface 311 and a second interface 312, the caliber of the first interface 311 is adapted to the caliber of the particle outlet 211, so that the particles can enter the mouth closer 31 without obstruction; the caliber of the second interface 312 is adapted to the caliber of the pipe 32, so that the particles can enter the pipe 32 without obstruction; the caliber of the particle outlet 211 is larger than the caliber of the pipe 32, thereby reducing the cross-sectional area of ​​the conveying channel 3, thereby increasing the conveying air pressure, and further facilitating the conveying of the cut particles to the next link, and more conveniently conveying the cut particles.

[0035] On the basis of the above embodiments, further, the closing device 31 is provided with a light-transmitting window 313 and an observation window 314. The light-transmitting window 313 is used to illuminate the closing device 31, and then reflect light into the cavity 21, so that the condition in the cavity 21 can be seen from the light-transmitting window 313, so as to facilitate the control of the pelletizing process.

[0036] The above is a detailed introduction to a granulator provided in an embodiment of the utility model. For a person skilled in the art, according to the idea of ​​the embodiment of the utility model, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the utility model.
