[0036] With reference to Figure 2 , Figure 3 With reference to Figure 5The anti-blocking assembly 5 further comprises an air pressure box 56, the outer wall of the air pressure box 56 is fixedly connected with the inner wall of the atomizer 1, the bottom end of the air pressure box 56 is fixedly connected with an air pressure pipe 57, the inside of the air pressure pipe 57 is communicated with the inside of the air pressure box 56, the inner wall of the air pressure box 56 is pistonically connected with a pressure receiving block 510, the transverse section shape of the pressure receiving block 510 is rectangular, and the upper portion of the pressure receiving block 510 is provided with a triangular corner cut, through the arrangement of the corner cut, it is ensured that the pressure receiving block 510 can move towards the direction of entering the air pressure box 56 after the corner cut is forced, the outer wall of the pressure receiving block 510 is elastically connected with the inner wall of the air pressure box 56 through a spring two 58, one end of the spring two 58 is fixedly connected with the outer wall of the pressure receiving block 510, the other end of the spring two 58 is fixedly connected with the inner wall of the air pressure box 56, the inner wall of the air pressure pipe 57 is pistonically connected with a push rod 59, the length of the push rod 59 is longer than the difference between the top height of the hole plate 51 in the initial state and the bottom height when the sieve frame 43 rotates to the rightmost end.

[0037] Working principle: in use, the staff first starts the equipment power supply, so that the hot gas pipe 2 sprays hot gas, at the same time, the emulsion is sprayed into the inside of the atomizer 1 through the feeding pipe 3, at this time, the emulsion is condensed into granular under the action of the hot gas sprayed by the hot gas pipe 2, and moves downward under the action of gravity.

[0038] When the emulsion particles move downward, the emulsion particles fall to the left half of the sieve frame 43, and enter the inside of different moving grooves 44 under the action of gravity, since the bottom of the moving groove 44 is provided with a round corner, at this time, the emulsion particles in the inside of the same moving groove 44 can be arranged in a linear shape.

[0039] At the same time, in the process of starting the equipment, the motor 41 is in the starting state, so the motor 41 drives the rotating shaft 42 to rotate, and drives the sieve frame 43 to rotate back and forth, and in the process of rotating, the emulsion particles in the inside of the moving groove 44 move left and right on a line where the sieve hole 45 is located, when the emulsion particles with a diameter smaller than the sieve hole 45 move above the sieve hole 45, they pass through the sieve hole 45 under the action of gravity and fall into the inside of the receiving drawer one 46, when the emulsion particles with a diameter larger than the sieve hole 45 move to the sieve hole 45, since their diameter is larger, they cannot pass through the sieve hole 45, so they continue to roll.

[0040] When the sieve frame 43 rotates to the right side and is in the lower end position, at this time, the emulsion particles with a larger diameter which smoothly pass through the sieve hole 45 can move rightwards under the action of gravity until entering the inside of the receiving drawer two 47, since the falling range of the emulsion particles is in the left half area, even the emulsion particles generated when the right side part of the sieve frame 43 is in the downward inclined position, at least need to roll from the left half position to the rightmost side in the moving groove 44, so it can ensure that the rolling range of the smaller particles is sufficient, and it is not easy to appear that the smaller particles are blocked and mistakenly enter the larger particle area.

[0041] Meanwhile, when the screen frame 43 rotates to the leftmost or rightmost side, the outer wall of the screen frame 43 extrudes the pressure block 510, so that the pressure block 510 enters the air pressure box 56, so that the air pressure inside the air pressure box 56 increases, so that the gas inside the air pressure box 56 enters the inside of the air pressure pipe 57, so that the air pressure inside the air pressure pipe 57 increases, so that the push rod 59 is forced to move upward, thereby pushing the control block 52, and the control block 52 drives the hole plate 51 and the push block 53 to move upward, so that the push block 53 enters the screen hole 45, thereby preventing the screening from being affected due to the fact that part of the emulsion particles are stuck in the screen hole 45.

[0042] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application have been described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
