[0002] A granulator is an industrial device that physically processes powdered materials into granules of specific shapes and sizes to enhance their flowability, stability, and ease subsequent processing or use. Widely used in industries such as pharmaceuticals, food, chemicals, and battery materials, granulators can produce granules using various processes, including dry, wet, spray drying, or extrusion, tailored to material characteristics and production requirements. These processes ensure uniformity and quality, meeting the standards of various industrial applications. The design and selection of a granulator require consideration of factors such as material characteristics, the desired particle size and shape, production efficiency, energy consumption, and cost. A high-quality granulator not only improves production efficiency but also ensures final product quality, meeting the specific requirements for granular materials across various industries. With the advancement of industrial technology, granulators are constantly undergoing technological innovation and performance optimization to adapt to market changes and user needs.

[0003] A search revealed an existing patent (publication number: CN207357106U) that discloses a "granulator comprising a hopper and a drum driven to rotate by a motor, the peripheral wall of the drum being composed of a plurality of squeezing rollers, a support frame being provided below the hopper, the two ends of the drum being hingedly connected to the two side walls of the support frame, the two side walls of the support frame to which the drum is hingedly connected being each provided with an arc-shaped snap-in slot, and a screen being provided, the two opposite side edges of the screen being respectively insertable into the two snap-in slots and deforming to conform to the shape of the slots.

A second motor 105 and a first motor 104 are fixedly provided at the lower middle position of the front end and the rear end of the feeding side wall 103 respectively through brackets.

[0031] Specifically, when in use, according to actual needs, the user opens the electric feeding valve and feeds materials into the feeding port 101. The four crushing rollers 102 are respectively driven by the first motor 104 and the second motor 105 to fully crush the input materials.

[0032] Reference Figure 3 、 Figure 4 、 Figure 5 and Figure 6 : A third motor 201 is fixedly provided at the lower middle position on one side of the feeding side wall 103 through a bracket, and the output end of the third motor 201 is connected to a transmission shaft 202 through a synchronous belt and a synchronous wheel. A vertical bevel gear 204 is fixedly provided at the center of one end of the transmission shaft 202, and the vertical bevel gear 204 is meshed with a horizontal bevel gear 205. The center of the lower end of the horizontal bevel gear 205 is fixedly connected to a rotating shaft 203, and the lower end of the rotating shaft 203 is rotatably set to the center of the upper end of the porous bin 302. Four maces 208 are fixedly provided on the shaft body of the rotating shaft 203 near the lower end position in a centrally symmetrical manner. The shaft body of the rotating shaft 203 is centrally symmetrically divided into three rows in the vertical direction, and each row is provided with four cross bars. Four blade paddles 206 are uniformly penetrated and rotated on the shaft body of each cross bar. A scraper 207 is fixedly provided at the end of each cross bar. The lower end of the mixing chamber 209 is fixed to the upper end of the particle discharging chamber 301, and the scraper 207 is close to the inner wall of the mixing chamber 209 and the particle discharging chamber 301;

[0033] Specifically, the third motor 201 drives the transmission shaft 202 and the vertical bevel gear 204 to rotate, driving the horizontal bevel gear 205 that is well meshed with the vertical bevel gear 204 to rotate, and the rotating shaft 203 rotates accordingly. Each cross bar rotates at the same time, and the materials entering the mixing chamber 209 are fully stirred. The multiple blade paddles 206 rotate with each cross bar to cut the materials well.

The side wall of the mixing chamber 209 is penetrated. An adhesive interface is fixedly provided on the wear plate, so that an appropriate amount of adhesive can be added to assist the material in granulation as needed. The three scrapers 207 rotate with the rotating shaft 203 to scrape the inner wall of the mixing chamber 209 well, effectively avoiding the residue of material on the inner wall of the mixing chamber 209. At the same time, the upper end of the porous bin 302 is designed with a frustum side arc. Under the scraping of the three scrapers 207, the finely cut material is well guided to the space between the inner side of the particle discharge chamber 301 and the outer side of the porous bin 302 and fully enters the multiple holes on the surface of the porous bin 302 under the good scraping of the three scrapers 207.

[0034] Reference Figure 3 、 Figure 4 、 Figure 5 and Figure 6 : A discharging guard plate 305 is fixedly provided at the lower end of the discharging chamber 301, a porous bin 302 is slidably provided on the inner wall of the discharging chamber 301, a cylindrical blade 303 is slidably provided on the inner wall of the porous bin 302, a sliding rod is fixedly connected to the cylindrical blade 303 through a bracket, an electric cylinder 304 is slidably provided at the lower end of the sliding rod, a discharging stop 306 is fixedly provided at the center of the upper end of the electric cylinder 304, and the discharging stop 306 is in the shape of a truncated cone;

[0035] Specifically, electric cylinder 304 is an electrically driven linear motion actuator. It utilizes an internal or external motor to drive a precision ball or roller screw, achieving high-speed, precise reciprocating motion. It can handle loads ranging from several kilograms to tens of tons. Users can choose Lim-Tek's IMB series or other similar products as needed. Electric cylinder 304, via a slide rod and bracket, drives a cylindrical blade 303, which slides against the inner wall of porous bin 302, to reciprocate vertically. This effectively cuts the material discharged from the multiple holes of porous bin 302 into pellets. The pellets then fall naturally under the influence of gravity and, guided by a discharge stop 306 and a discharge guard plate 305, fall neatly into a collection device below.

[0036] Working principle: The material enters the crushing mechanism 1 through the feed port 101. The feed port 101 is equipped with an electric valve to control the proper feeding of the material. Four crushing rollers 102 are provided inside the crushing mechanism 1, two of which are driven by the first motor 104 and the other two by the second motor 105, ensuring that the material is fully crushed before entering the mixing and cutting mechanism 2. The crushed material enters the mixing chamber 209. The third motor 201 drives the vertical bevel gear 204 and the pre-supported well-meshed horizontal bevel gear 205 through the transmission shaft 202, thereby driving the rotating shaft 203 to rotate. The four maces 208 and the multiple blade paddles 206 mounted on the shaft 203 work together to further fully stir and finely divide the material. The four maces 208 perform secondary crushing on lumps that may form during the stirring process to ensure uniformity and fine processing of the material. An adhesive interface is fixedly provided through the side wall of the stirring chamber 209 to facilitate the addition of adhesive when needed to assist in granulation of the material. The three scrapers 207 rotate with the rotating shaft 203 to scrape the inner wall of the stirring chamber 209 to prevent material residue and guide the divided material to the granulation mechanism 3.

[0037] Secondly, the stirred material enters the multiple holes of the porous bin 302 through the action of the scraper 207, and a cylindrical blade 303 is slidingly set on the inner wall of the particle discharge chamber 301. The cylindrical blade 303 is connected to the electric cylinder 304 through a slide rod. Driven by the electric cylinder 304, the cylindrical blade 303 reciprocates in the vertical direction, and cuts the material discharged from the multiple holes of the porous bin 302 into required particles. The cut particles fall naturally under the action of gravity, and are guided by the discharge stop 306 and the discharge guard plate 305 to fall smoothly into the collection device below. The three mechanisms are arranged in sequence from top to bottom. The integrated design significantly improves the granulation efficiency, is easy to operate and maintain, and is suitable for a variety of industrial granulation needs.
