[0016] The working principle and beneficial effects of the present invention are as follows:

[0017] 1. A pretreatment component is provided in the present invention. The first servo motor can drive each first feeding cylinder in the rotating cylinder to perform circular motion. Furthermore, the second grinding ring on the filter plate can be driven to rotate uniformly through the connecting rod. In cooperation with the grinding block and the first grinding ring, the raw materials can be comprehensively ground until they reach the qualified state before being fed through the filter plate. Moreover, under the grinding action, the problem of uneven mixing caused by a large amount of raw materials being put in at one time can be effectively avoided. Meanwhile, during the movement of each first feeding cylinder, the transmission rod in each first feeding cylinder can be driven to rotate automatically in cooperation with the circular gear and the internal gear. The additive can be evenly conveyed to the atomizing nozzles through each spiral blade, and the additive can be evenly sprayed in the device housing through the circular motion of each atomizing nozzle. Thus, the raw materials during the feeding process can be evenly sprayed. Additionally, during the circular motion of the transmission rod, each mixing plate and the stirring rod can be toggled to perform reciprocating up and down motion during the circular motion through the first limiting rod and the first limiting groove. Further, the raw materials and the additive can be efficiently and evenly mixed and stirred, ensuring the smooth progress of the subsequent granulation work and the stability of the granulation particle quality, increasing the diversity and efficiency of the granulation device.

[0018] 2. A second feeding cylinder and a spiral rod are provided in the present invention. By the forward rotation of the spiral rod, the second feeding cylinder feeds through the first through groove at the middle side end and then discharges through the second through groove at the top side end, enabling convenient and efficient material turning work inside the device. Thus, the mixing efficiency and mixing uniformity between the raw materials and the additive can be further improved. When the mixing work is completed, by the reverse rotation of the spiral rod, it can feed through the first through groove at the middle side end and then discharge through the discharge funnel at the bottom side end, ensuring the stability of the subsequent granulation work. Meanwhile, in cooperation with the electric heating tube, the humidity of the material can be reduced, making the raw materials easier to form particles, accelerating the granulation speed, improving the production efficiency, and reducing energy consumption and costs.

[0019] 3. The present invention is provided with an adjusting component. Driven by the meshing of a worm and a worm wheel, through the rotation of a turntable and a lever, the guide plate can be driven to rotate by 90° in cooperation with a guide groove. Furthermore, the four forming plates can be driven to perform a 90° circular motion through an adapter plate, completing the convenient switching of the four forming plates. By using the forming holes with different diameters on the four forming plates, granulation work with different diameters can be carried out on the materials discharged from the discharge funnel, conveniently and stably adjusting the granulation diameter. Moreover, by means of the cooperation of a clamping groove and a clamping rod, the forming plate can be conveniently and stably disassembled and installed, and thus the forming plate can be conveniently and stably overhauled, maintained and replaced, ensuring the accuracy of the forming work after the device has been working for a long time. And by rotating a threaded rod, the position of a driven rod can be conveniently adjusted, and then the reciprocating movement distance of a driven frame can be adjusted in cooperation with a rotating plate. At this time, the contact time between the reciprocating driven frame and the forming plate also changes, and thus the granulation length of the material can be conveniently adjusted according to requirements, increasing the diversity of the use of the granulation device, and at the same time improving the practicability and applicability of the granulation device.

During the circular motion of the transmission rod 506, the first limiting rod 519 and the first limiting groove 520 can drive each mixing plate 516 and the stirring rods 517 to perform reciprocating motion up and down during the circular motion, so as to further mix and stir the raw materials and additives efficiently and evenly, thereby ensuring the smooth progress of the subsequent granulation work and the stability of the material quality, and increasing the diversity and efficiency of the use of the granulation device.

[0053] In this embodiment, four guiding grooves 1310 are provided. The four guiding grooves 1310 are equally angularly distributed on the guiding plate 1309. The side end face of the guiding plate 1309 is arc-shaped. The side end face of the guiding plate 1309 is in contact with the side end face of the limiting disc 1306. The connecting plates 1311 are symmetrically distributed on both sides of the second connecting shaft 1308. The connecting plates 1311 are in a "cross" shape. Four positioning frames 1313 are provided. The four positioning frames 1313 are distributed around the connecting plates 1311. The positioning frames 1313 and the clamping rods 1315 correspond to the clamping grooves 1312 one by one. The second connecting shaft 1308 is fixed in the middle part of the connecting plates 1311. By using the cooperation of the clamping grooves 1312 and the clamping rods 1315, the forming plate 1316 can be disassembled and installed conveniently and stably. Furthermore, the forming plate 1316 can be conveniently and stably overhauled, maintained and replaced.

[0054] In this embodiment, the positioning frames 1313 and the forming plates 1316 correspond to each other one by one. The forming holes 1317 are equally angularly distributed on the forming plates 1316. The diameters of the forming holes 1317 on the four forming plates 1316 gradually decrease in the clockwise direction. The diameter of the forming plate 1316 is larger than the side end opening diameter of the discharging funnel 10. The side end face of the discharging funnel 10 is in contact with the side end face of the forming plate 1316. The other side end face of the forming plate 1316 is in contact with the cutting blade 1323. The length of the cutting blade 1323 is equal to the length of the driven frame 1322. The length of the rotating plate 1319 is equal to half of the length of the driven frame 1322. The top of the driven frame 1322 is welded and fixed with a second limiting rod 1324. A second limiting groove 1325 is formed on the inner wall of the fixed frame 12. The end part of the second limiting rod 1324 is limited and slidably connected in the second limiting groove 1325. By switching the four forming plates 1316 and cooperating with the forming holes 1317 with different diameters on the four forming plates 1316, the materials discharged inside the discharging funnel 10 can be formed into pellets with different diameters, and furthermore, the adjustment of the pellet diameter can be completed conveniently and stably.

[0055] It should be noted that the present invention is a granulation device with adjustable granule diameter. First, the staff can proportionally mix the raw materials and the additives to be used. Subsequently, the staff can lift the magnetic cover plate 3 at the top of the feeding funnel 2, and then the staff can convey the prepared raw materials into the device housing 1 and convey the prepared additives into the fixed cylinder 510 through the use of the liquid inlet pipe 4. Then, the staff can control the first servo motor 501 to start. At this time, under the driving action of the first servo motor 501, the output shaft can drive the rotating cylinder 502 to rotate. Under the rotation of the rotating cylinder 502, each first feeding cylinder 503 can be driven to perform a circular motion, and then the filter screen plate 514 can be driven to rotate through the connecting rod 513. At this time, under the rotation of the filter screen plate 514, the second grinding ring 515 at the top can be driven to rotate stably. Under the continuous rotation of the second grinding ring 515, the raw materials can be comprehensively and stably ground in combination with the grinding block 511 and the first grinding ring 512. And under the continuous rotation of the second grinding ring 515, the materials can be conveyed downward through the filter screen plate 514 for feeding only until the materials are ground to a qualified state. And under the grinding action, the problem of uneven subsequent mixing caused by the one-time feeding of a large amount of raw materials can be effectively avoided;

[0056] Meanwhile, during the circular motion of each first feeding cylinder 503, the transmission rod 506 can be driven to perform a synchronous motion. And under the circular motion of each transmission rod 506, the circular gear 508 at the top can be driven to perform a circular motion within the internal gear 509. At this time, under the meshing drive of the internal gear 509 and the circular gear 508, the transmission rod 506 during the revolution can be automatically rotated within the corresponding first feeding cylinder 503. Under the rotation of the transmission rod 506, each spiral blade 507 can be driven to rotate stably. At this time, the additives in the fixed cylinder 510 can be conveyed into the first feeding cylinder 503 through the fixed screen plate 505. And by using the rotation of each spiral blade 507, the additives can be uniformly conveyed to the atomizing nozzles 504. And through the circular motion of each first feeding cylinder 503, each atomizing nozzle 504 can be driven to perform a synchronous circular motion, so that the additives can be evenly sprayed within the device housing 1 to evenly spray the raw materials during the feeding process;

[0057] During the circular motion of the transmission rod 506, it can drive the mixing plate 516 to perform circular motion. At this time, during the circular motion of the mixing plate 516, it can drive the scraping rod 518 to perform synchronous circular motion, thereby enabling automatic scraping and cleaning of the inner wall of the device housing 1, avoiding the adhesion of materials to the inner wall of the device housing 1 and having an adverse impact on the next granulation work. And during the circular motion of the mixing plate 516, the first limiting rod 519 at the side end of the mixing plate 516 slides in a limited manner in the first limiting groove 520 on the outer wall of the second feeding cylinder 6. At this time, under the guiding action of the first limiting groove 520, the mixing plate 516 in circular motion can be driven by the first limiting rod 519 to perform automatic and stable up-and-down reciprocating motion. Cooperating with each stirring rod 517, the raw materials and additives can be efficiently and evenly mixed and stirred, thus ensuring the smooth progress of the subsequent granulation work and the stability of the material quality. And during the rotation of the rotating cylinder 502, it can also drive the screw rod 9 to rotate stably in the forward direction inside the second feeding cylinder 6. At this time, under the continuous forward rotation of the screw rod 9, the screw feeding direction of the screw rod 9 is upward. Therefore, the materials in the device housing 1 can enter through the first through groove 7 at the middle side end of the second feeding cylinder 6. Cooperating with the continuous rotation of the screw rod 9, they can be transported to the top through the second feeding cylinder 6 and then discharged from the second through groove 8 at the top side end of the second feeding cylinder 6. Repeating this process, the materials inside the device can be conveniently and efficiently turned over, thereby further improving the mixing efficiency and mixing uniformity between the raw materials and additives;

[0058] When the mixing work is completed, the first servo motor 501 is used to drive the rotating cylinder 502 to rotate in the reverse direction, thereby driving the screw rod 9 to rotate in the reverse direction. At this time, under the reverse rotation of the screw rod 9, the screw feeding direction of the screw rod 9 is downward. At this time, the raw materials in the device housing 1 enter through the first through groove 7 at the middle side end and then are discharged through the discharge funnel 10 at the bottom side end. During the discharging process, cooperating with the electric heating tube 11 can reduce the humidity of the materials, making the raw materials easier to form particles. Subsequently, the materials are formed and discharged through each forming hole 1317 on the forming plate 1316. At the same time, under the driving action of the second servo motor 1318, the rotating plate 1319 can be driven to rotate, thereby driving the driven rod 1321 to perform circular motion. At this time, under the circular motion of the driven rod 1321, combined with the limitation of the second limiting rod 1324 and the second limiting groove 1325, the driven frame 1322 can be driven to perform stable forward and backward reciprocating motion. Cooperating with the cutting blade 1323, the formed and discharged materials can be cut to complete the granulation work of the materials. Subsequently, the materials fall into the collection box 14 below to complete the automatic collection work;

[0059] Before the device works, the staff can rotate the worm 1302 inside the protective frame 1301. Under the rotation of the worm 1302, the first connecting shaft 1304 can be driven to rotate by the meshing worm wheel 1303, and then the turntable 1305, the limit disk 1306 and the lever 1307 can be driven to rotate synchronously. Under the circular motion of the lever 1307, the guide plate 1309 can be driven to rotate intermittently by 90° through the guide groove 1310. And when the guide plate 1309 stops rotating, by using the fitting of the guide plate 1309 and the limit disk 1306, the guide plate 1309 can be stably limited to prevent the guide plate 1309 from shaking or shifting when it stops rotating. By using the 90° rotation of the guide plate 1309, the connecting plate 1311 can be driven to rotate by the second connecting shaft 1308, and then the corresponding forming plate 1316 can be driven to rotate by 90° through the four positioning frames 1313, so that the switching alignment between the four forming plates 1316 and the discharge funnel 10 can be conveniently completed. By switching the four forming plates 1316 and matching the forming holes 1317 with different diameters on the four forming plates 1316, the materials discharged inside the discharge funnel 10 can be formed and granulated with different diameters, and then the adjustment of the granulation diameter can be conveniently and stably completed;

[0060] Before the device works, the staff can rotate the threaded rod 1320 inside the rotating plate 1319. Under the rotation of the threaded rod 1320, the driven rod 1321 connected by threads can be driven to move inside the rotating plate 1319 to adjust the position of the driven rod 1321. After the position of the driven rod 1321 is adjusted, during the rotation of the rotating plate 1319, the reciprocating movement distance of the driven frame 1322 toggled by the driven rod 1321 also changes. After the reciprocating movement distance of the driven frame 1322 changes, the time when the reciprocating driven frame 1322 needs to contact the forming plate 1316 also changes. Since the formed material is continuously discharged, after the time when the reciprocating driven frame 1322 needs to contact the forming plate 1316 also changes during the reciprocating movement, the length of the discharged material changes. Therefore, the length of the cut material changes. That is to say, the farther the driven rod 1321 is from the output shaft of the second servo motor 1318, the farther the reciprocating movement distance of the driven frame 1322 toggled by it is. Therefore, the time when the reciprocating driven frame 1322 needs to contact the forming plate 1316 becomes longer, so the length of the cut material becomes longer. On the contrary, the closer the driven rod 1321 is to the output shaft of the second servo motor 1318, the closer the reciprocating movement distance of the driven frame 1322 toggled by it is. Therefore, the time when the reciprocating driven frame 1322 needs to contact the forming plate 1316 becomes shorter, so the length of the cut material becomes shorter. Thus, the granulation length of the material can be conveniently adjusted according to requirements. Moreover, after the device finishes working, the staff can pull out the latch 1315 on the positioning frame 1313 until the latch 1315 moves out of the card slot 1312 on the connecting plate 1311, and then the disassembly work of the forming plate 1316 can be conveniently completed. Similarly, by pulling out the latch 1315 on the positioning frame 1313 in advance, then inserting the positioning frame 1313 on the connecting plate 1311, and then the staff can release the latch 1315. At this time, under the elastic action of the return spring 1314, the latch 1315 can be driven to automatically engage into the card slot 1312 on the connecting plate 1311, and the clamping installation of the forming plate 1316 can be conveniently completed. By conveniently disassembling and assembling the forming plate 1316, the forming plate 1316 can be conveniently and stably overhauled, maintained or replaced, ensuring the stability of its subsequent working state.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
