[0024] The following combines the attached Figures 1-5 This application will be further described in detail

[0025] The embodiments of this application disclose a granulation and feeding device for granulator production. Refer to Figure 1 Figure 5 A granulation and feeding device for granulator production includes a barrel 1. A feeding hopper 2 is fixedly connected to the top of the barrel 1. A discharging hopper 3 is fixedly connected to the bottom of the barrel 1. A spiral conveying blade 4 is arranged inside the barrel 1. A cleaning and anti-blocking mechanism 5 is arranged inside the barrel 1;

[0026] The cleaning and anti-blocking mechanism 5 includes an annular scraping plate 501. The outer side of the annular scraping plate 501 is attached to the inner side wall of the barrel 1. One side of the annular scraping plate 501 is threadedly sleeved with a threaded rod 502. One end of the threaded rod 502 is fixedly sleeved with a gear 503. A rack plate 504 is meshed and connected to the gear 503. The bottom of the rack plate 504 is fixedly connected with an ejecting block 505 adapted to the discharging hopper 3. One end of the threaded rod 502 penetrates through the outside of the barrel 1. One end of the threaded rod 502 is fixedly connected with a motor 506. The threaded rod 502 is rotatably connected to the barrel 1. During use, by setting the cleaning and anti-blocking mechanism 5, the inside of the barrel 1 is knocked, and the raw materials adhered to the inner side wall of the barrel 1 can be scraped off, so that the raw materials are discharged from the discharging hopper 3, and at the same time, the discharging hopper 3 can be dredged to avoid blockage.

[0027] Refer to Figure 2, a guiding groove 5012 is provided at the bottom end of the inner side wall of the barrel 1. A guiding block 5011 is fixedly connected to the outer side surface of the annular scraping plate 501 at a position corresponding to the guiding groove 5012. By providing the guiding block 5011 and the guiding groove 5012, the annular scraping plate 501 can be limited to prevent it from rotating self, so that the raw materials remaining on the inner wall of the barrel 1 can be scraped off.

[0028] Refer to Figure 3 , a reserved groove 5031 is provided on the inner side wall of the barrel 1 at a position corresponding to the gear 503 and the rack plate 504. An adjusting groove is provided at the top end inside the reserved groove 5031 at a position corresponding to the rack plate 504. By providing the reserved groove 5031, sufficient transmission space can be reserved for the transmission position of the gear 503 and the rack plate 504. By providing the adjusting groove, the rack plate 504 can move up and down, which can play a guiding and limiting role at the same time, so that the ejecting block 505 moves up and down, thereby dredging the feeding hopper 3 to prevent it from being blocked.

[0029] Refer to Figure 3 , the top of the rack plate 504 is fixedly connected with a top plate 5041. The sectional area value of the top plate 5041 in a top view is greater than the sectional area value of the adjusting groove in a top view. By providing the guiding block 5011, when the device is not in use, the top plate 5041 can be in contact with the barrel 1 to play a dust-proof role.

[0030] Refer to Figure 4 , a material guiding groove 31 is provided on the inner side wall of the barrel 1 at a position corresponding to the feeding hopper 3. The gradient value of the material guiding groove 31 gradually decreases along the position close to the feeding hopper 3. By providing the material guiding groove 31 and the gradient value of the material guiding groove 31 gradually decreasing along the position close to the feeding hopper 3, when the raw materials are conveyed by the spiral conveying blade 4, it is convenient for the raw materials to be discharged when they are conveyed to the position of the feeding hopper 3.

[0031] Refer to Figure 4 , the guiding groove 5012 and the material guiding groove 31 are interconnected. By setting like this, the raw materials in the guiding groove 5012 can also be conveyed into the material guiding groove 31 for discharging.

[0032] Refer to Figure 5 , one end of the threaded rod 502 far away from the motor 506 is fixedly connected with a connecting block 5021. An elastic rope 5022 is fixedly connected to the outer side surface of the connecting block 5021. One end of the elastic rope 5022 is fixedly connected with an elastic ball 5023. When the threaded rod 502 rotates, the connecting block 5021 is driven to rotate synchronously. At this time, under the action of centrifugal force, the elastic rope 5022 can be straightened, and the elastic ball 5023 can be made to impact the inner wall of the barrel 1. Under the action of vibration, the raw materials still adhered after being scraped by the annular scraping plate 501 can fall off, playing an auxiliary cleaning role.

[0033] Working principle: When transporting raw materials, first put the raw materials into the interior of the barrel 1 through the feeding hopper 2, and then under the action of the spiral conveying blade 4, convey the discharging hopper 3 into the interior of the granulator;

[0034] After long-term use, when there are residues on the inner wall of the barrel 1 or the discharging hopper 3 is blocked, by turning on the motor 506, it drives the threaded rod 502 to rotate. At this time, under the action of the guiding block 5011 and the guiding groove 5012, the annular scraping plate 501 can move along the direction of the threaded rod 502, so as to scrape off the residues on the inner wall of the barrel 1;

[0035] When the threaded rod 502 rotates, it drives the connecting block 5021 to rotate synchronously. At this time, under the action of centrifugal force, the elastic rope 5022 can be straightened, and the elastic ball 5023 impacts the inner wall of the barrel 1. Under the action of vibration, the raw materials still adhering after being scraped by the annular scraping plate 501 can fall off, playing an auxiliary cleaning role;

[0036] In addition, since the threaded rod 502 is meshed and connected with the rack plate 504 through the gear 503, the threaded rod 502 will drive the rack plate 504 to move upward when rotating. Under the action of the ejecting block 505, the interior of the discharging hopper 3 can be dredged, thereby avoiding its blockage.

[0037] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present utility model.
