Description

Technical Field

[0002] Granulators are widely used in industries and fields such as pesticides, pharmaceuticals, fertilizers, chemical building materials, etc. Most of the granulators in the prior art adopt spiral extrusion type. Different additives are added to the resin according to different uses. After heating, mixing and extrusion, the resin raw materials are made into granular products suitable for secondary processing. Due to the structural characteristics of the granulator itself, the material particle size (including length and cross-sectional particle size) is not easy to flexibly adjust and control, and cannot meet application requirements. At the same time, after the granulation is completed, it is more time-consuming and laborious to screen the particles. Therefore, it is necessary to reduce the cost while having an adjustable granulation size of the granulator and an integrated ring granulating device that can be screened. Summary of the invention

[0051] Working process of the gap-adjustable additive granulation device:

[0052] The staff puts the powder material mixed with multiple additives into the mixing barrel 54 through the feeding pipe 57, and the material sinks from the mixing barrel 54 to the collecting barrel 55. The power switch of the third motor 51 is turned on, and the third motor 51 drives the rotating wheel 56 to rotate. The rotating rotating wheel 56 scrapes the mixed powder into the first shell 22 through the first through hole. The staff turns on the switch of the first motor 21, and the first motor 21 drives the pressing blade 25 to rotate through the first central axis 24. The pressing blade 25 with a spiral structure can squeeze the additive powder to the end of the first shell 22 close to the mold 4 and the powder is compacted and accumulated in this part. After the powder is compacted, it is arranged through the third through hole, the fourth through hole and the fifth through hole to form an outer shape. The continuous strip with the same size as the fourth through hole, the staff turns on the second motor 32 switch, the second motor 32 drives the scraper 34 to rotate, the scraper 34 and the end face of the second adjusting plate 46 form a shear structure, and the additive strip is cut into particles, which fall into the screening device 6 below the mold 4, and the additive particles spirally slide down in the screen assembly 64 by the gravity potential energy, and are screened by the coarse material net 642 and the fine material net 643 during the sliding process. Large particles are discharged from the coarse material port 644, and qualified products are discharged from the receiving port 645, and broken particles and powder are discharged from the powder port 646. The staff packs the qualified products for shipment, and the large particles, broken particles and powder are recycled, and the above work is repeated for processing.

[0053] During use, the staff can increase or decrease the rotation speed of the pressure-pressing blade 25 by adjusting the knob of the first motor 21 to control the squeezing force of the pressure-pressing device 2 on the additive powder;

[0054] The cutting length can be adjusted by adjusting the knob of the second motor 32 to control the rotation speed of the scraper 34;

[0055] The speed at which the additive mixed powder enters the first housing 22 is adjusted by adjusting the knob of the third motor 51 to control the rotation speed of the rotating wheel 56 .

[0056] The staff rotates the first rotation 4413, and the first knob 4413 drives the second discharge plate 4411 through the first adjusting rod 4412, and translates on the tracks of the second clamping strip 432 and the third clamping strip. The translation of the second discharge plate 4411 drives the change in the relative position of the third through hole and the fourth through hole, thereby reducing the lateral distance of the powder extrusion channel. Similarly, the second knob 463 drives the third discharge plate 461 to move through the second adjusting rod 462, changing the relative position of the fourth through hole and the fifth through hole, thereby reducing the vertical distance of the powder extrusion channel. The staff can adjust the outer size of the discharge particles by the relative position of the first adjusting plate 44 and the second adjusting plate 46.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
