[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment:

[0024] The embodiment of the present invention provides a vacuum feeding whole granulator. Through the design of the backflush component, the suction head is backflushed by using a high-pressure gas source to achieve automatic cleaning, without manual inspection and cleaning, which is efficient and fast, and greatly reduces the impact on the whole granulation processing progress, so as to solve the problems raised in the above background technology.

[0025] Please refer to Figures 1-5 , the present invention provides a technical solution:

[0026] A vacuum feeding whole granulator includes a whole granulator body 1 and a vacuum feeding mechanism 2. The whole granulator body 1 includes a frame 11. The bottom surface of the frame 11 is fixedly installed with a main body 12. A grain discharging bin 13 is placed at the bottom of the main body 12. The top surface of the frame 11 is fixedly installed with a feeding bin 14. The feeding bin 14 and the main body 12 are connected through. One side of the feeding bin 14 is fixedly installed with a driving motor 15 acting on the main body 12. Materials are fed into the feeding bin 14 through vacuum. At the same time, the driving motor 15 works. Under its action, the main body 12 starts to work to granulate the materials continuously falling from the feeding bin 14. The materials after granulation are directly dropped into the discharging bin 13 to achieve granulation processing.

[0027] Among them, the vacuum feeding mechanism 2 includes a vacuum feeding cylinder 22 fixedly installed on the top surface of the granulating machine body 1 through a mounting assembly 21. The vacuum feeding cylinder 22 is connected in a through manner with a high-pressure blower 24 located on the ground through a compression pipeline 23. The vacuum feeding cylinder 22 is connected in a through manner with a suction head 26 located inside the storage bin through a negative pressure pipeline 25. A backflush assembly 27 is arranged on the outer surface of the suction head 26. The backflush assembly 27 includes high-pressure gas flow channels 271 penetrating and installed on both sides of the outer surface of the suction head 26. A pulse valve 272 is fixedly installed at the top end of the high-pressure gas flow channel 271. A high-pressure gas source connection port 273 is fixedly installed on one side of the pulse valve 272. The pulse valve 272 is located on the top surface of a limit mounting disc 274. The high-pressure gas source connection port 273 is connected in a through manner with an external high-pressure gas source. When the high-pressure blower 24 operates, negative pressure is generated inside the vacuum feeding cylinder 22 through the compression pipeline 23. At this time, under the action of the negative pressure, the suction head 26 sucks the materials inside the storage bin and introduces them into the vacuum feeding cylinder 22 through the negative pressure pipeline 25. When the suction head 26 is blocked during the vacuum feeding process, the feeding is paused. At the same time, the pulse valve 272 quickly opens and closes the valve through a control signal, thereby generating a pulsed air flow, which rushes into the inside of the suction head 26 through the high-pressure gas flow channel 271 in the direction opposite to the suction direction, so as to quickly and automatically clean it, ensuring that the suction head 26 can suck materials smoothly, without manual inspection and cleaning, which is efficient and fast, and greatly reduces the impact on the granulation processing progress.

[0028] In addition, in this embodiment, please refer to Figure 4 , the mounting assembly 21 includes a positioning chassis 211 sleeved on the bottom end of the outer surface of the vacuum feeding cylinder 22. Mounting angle brackets 212 are fixedly installed on the four sides of the positioning chassis 211. And through the provided positioning chassis 211 and mounting angle brackets 212, it is convenient to fixedly install the vacuum feeding cylinder 22 and the feeding bin 14, ensuring the stable and reliable feeding and discharging.

[0029] In addition, in this embodiment, please refer to Figure 2 , a filtration box 231 is arranged on the compression pipeline 23. A blanking solenoid valve 221 is arranged at the bottom end of the vacuum feeding cylinder 22. During the vacuum feeding process, the air sucked out by the high-pressure blower 24 can be filtered through the provided filtration box 23, avoiding the entry of material dust and dirt into the high-pressure blower 24, preventing mechanical damage to its interior. After the vacuum feeding is completed, the blanking solenoid valve 221 can be started to automatically open, and at this time, the materials inside the vacuum feeding cylinder 22 are automatically fed into the feeding bin 14.

[0030] In addition, in this embodiment, please refer to Figure 2, a machine base 241 is fixedly installed at the bottom of the high-pressure blower 24. An air suction port 242 is arranged at one end of the high-pressure blower 24 close to the compression pipeline 23, and an air exhaust port 243 is arranged at the other end of the high-pressure blower 24 away from the air suction port 242. A filter 244 is fixedly installed at the end of the air exhaust port 243 away from the high-pressure blower 24. The air discharged from the high-pressure blower 24 can be secondary filtered through the provided filter 244 to avoid polluting the external air and ensure the environmental air quality;

[0031] In addition, in this embodiment, please refer to Figure 3 , a limit mounting disc 274 is fixedly installed on the outer surface of the material suction head 26 near the top of the high-pressure gas flow channel 271. The top end of the high-pressure gas flow channel 271 passes through the inside of the limit mounting disc 274 and extends to its top surface. The limit mounting disc 274 is provided to facilitate the fixation of the high-pressure gas flow channel 271 and the pulse valve 272 to ensure stability.

[0032] In this embodiment, the implementation scenario is specifically as follows: During feeding, the high-pressure gas source connection port 273 is connected to an external high-pressure gas source in a through manner. The high-pressure blower 24 operates, and a negative pressure is generated inside the vacuum feeding cylinder 22 through the compression pipeline 23. At this time, under the action of the negative pressure, the material suction head 26 sucks the material inside the storage bin and introduces it into the vacuum feeding cylinder 22 through the negative pressure pipeline 25. When the material suction head 26 is blocked during the vacuum feeding process, the feeding is paused. At the same time, the pulse valve 272 quickly opens and closes the valve through a control signal, thereby generating a pulsed air flow, which rushes into the inside of the material suction head 26 in the direction opposite to the suction direction through the high-pressure gas flow channel 271 to quickly and automatically clean it, ensuring that the material suction head 26 can suck the material smoothly. Then, the vacuum feeding is resumed. After the feeding is completed, the high-pressure blower 24 pauses working, and at the same time, the blanking solenoid valve 221 is automatically opened. At this time, the material inside the vacuum feeding cylinder 22 automatically falls into the inside of the feed bin 14. At the same time, the drive motor 15 operates, and under its action, the main body 12 starts to work to granulate the material continuously falling from the feed bin 14. The material after granulation directly falls into the inside of the discharge bin 13 to achieve granulation. Overall, the high-pressure gas source is used to blow back the material suction head to achieve automatic cleaning, without manual inspection and cleaning, which is efficient and fast, and greatly reduces the impact on the granulation progress.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
