Detailed implementation manners

[0024] Referring to embodiments herein means that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0025] Embodiment 1: The feeding equipment for pill production, such as Figures 1 - 5As shown in the figure, it includes a mounting frame 1, a screening barrel 2, a feeding pipe 3, a discharging pipe 301, a first motor 5, a pushing frame 6, a fixing frame 7, a protective frame 8, a second motor 9, a driving roller 10, a conveying belt 11, a pushing plate 1101 and a protective shell 28. The screening barrel 2 is installed on the mounting frame 1. A feeding pipe 3 is arranged on one side of the screening barrel 2. A discharging pipe 301 is arranged on the side of the screening barrel 2 away from the feeding pipe 3. A first motor 5 is installed on the side of the screening barrel 2 close to the discharging pipe 301. A protective shell 28 is installed outside the first motor 5. The output shaft of the first motor 5 penetrates the screening barrel 2 and is connected to the pushing frame 6. A fixing frame 7 is installed at the lower part on the side of the mounting frame 1 close to the discharging pipe 301. A protective frame 8 is installed above the fixing frame 7. Driving rollers 10 are rotatably arranged on both sides of the protective frame 8. A conveying belt 11 is connected between the two driving rollers 10. Multiple pushing plates 1101 are fixedly connected to the conveying belt 11. A second motor 9 is installed on the fixing frame 7. The output shaft of the second motor 9 penetrates the protective frame 8 and is connected to one of the driving rollers 10. It further includes a screening rack 4, and a screening rack 4 is installed between the screening barrel 2 and the pushing frame 6.

[0026] When the device is needed for pill feeding, the staff puts the pills into the feeding pipe 3. Then the pills enter the interior of the screening barrel 2. Next, the staff starts the first motor 5 to drive the pushing frame 6 to rotate. The pills in the screening barrel 2 are stirred by the pushing frame 6, so that a large number of pills are gradually dispersed in the screening barrel 2. There will be certain impurities in the pills. During the process of stirring the pills by the pushing frame 6, some impurities will be separated from the pills. Then the impurities pass through the screening rack 4 and fall into the space between the screening barrel 2 and the screening rack 4. The pills after impurity removal are pushed into the discharging pipe 301 as the pushing frame 6 rotates and fall on the conveying belt 11. Then the staff starts the second motor 9 to drive the driving roller 10 to rotate. The pushing plates 1101 on the conveying belt 11 push the pills to be conveyed upward evenly for feeding. The protective shell 28 prevents foreign objects from damaging the first motor 5, so that impurities are removed during the stirring process of the pills, ensuring a certain efficacy and safety of the pills.

[0027] Embodiment 2: On the basis of Embodiment 1, as Figures 6 - 7 shown, it further includes a positioning plate 12, a first guide rod 13, a material blocking plate 14, a first elastic member 15, a connecting plate 16, a clamping ball and a second elastic member 17. A positioning plate 12 is installed below the discharging pipe 301. Two first guide rods 13 are respectively fixedly connected to both sides of the positioning plate 12. A material blocking plate 14 is slidably arranged between the two first guide rods 13. The material blocking plate 14 and the positioning plate 12 cooperate to block the discharging pipe 301. A first elastic member 15 is connected between the positioning plate 12 and the material blocking plate 14. The first elastic member 15 is sleeved on the first guide rod 13. Two connecting plates 16 are rotatably arranged on the side of the material blocking plate 14 close to the conveying belt 11. A second elastic member 17 is connected between the connecting plate 16 and the material blocking plate 14, and the pushing plate 1101 will contact the connecting plate 16.

[0028] To avoid a large number of pills falling onto the conveyor belt 11 and causing the pills to roll off the conveyor belt 11, the pills after impurity removal fall from the blanking pipe 301 onto the positioning plate 12 and the material blocking plate 14. When the staff starts the conveyor belt 11 to operate, the operation of the conveyor belt 11 causes the push plate 1101 to contact the two connecting plates 16. The two connecting plates 16 are stressed and drive the material blocking plate 14 to slide open along the first guide rod 13, and the first elastic member 15 is stressed and deformed. At this time, since the material blocking plate 14 is pulled to open the blanking pipe 301, the pills in the blanking pipe 301 fall onto the conveyor belt 11. When the push plate 1101 pulls the connecting plate 16 to a certain distance, the connecting plate 16 is stressed and flipped, and the second elastic member 17 is stressed and deformed, and the force of the second elastic member 17 is greater than the force of the first elastic member 15. After the connecting plate 16 is separated from the push plate 1101, the second elastic member 17 returns to its original state, driving the connecting plate 16 to flip and reset, and the first elastic member 15 returns to its original state and drives the material blocking plate 14 to slide and reset, so that the blanking pipe 301 is closed again, achieving intermittent blanking operation of the pills.

[0029] As Figure 8 shown, it further includes a support frame 18, a second guide rod 19, an isolation frame 20 and a third elastic member 22. Support frames 18 are installed on both sides of the feeding pipe 3. Two second guide rods 19 are arranged between the two support frames 18. Two isolation frames 20 are slidably arranged between the two second guide rods 19. A guide plate 21 is fixedly connected to the top of the isolation frame 20. Two third elastic members 22 are connected between the isolation frame 20 and the support frame 18.

[0030] To prevent dust from entering the screening barrel 2, the staff pulls the two guide plates 21 to slide the isolation frame 20 open along both sides of the second guide rod 19, and the third elastic member 22 is stressed and deformed. At this time, the staff can put the pills into the feeding pipe 3 and enter the interior of the screening barrel 2 for impurity removal. When it is not necessary to feed the pills, the staff releases the two guide plates 21, and the third elastic member 22 returns to its original state and drives the isolation frame 20 to slide and reset along the second guide rod 19, so that the inlet of the feeding pipe 3 is closed, achieving the effect of isolating the feeding pipe 3 and preventing foreign objects from entering the screening barrel 2 and affecting the impurity removal of the pills.

[0031] As Figure 9 shown, it further includes a liquid storage tank 23, a diversion pipe 24, a water pump 25, a spray head 26 and a protective cover 27. The liquid storage tank 23 is placed between the fixed frame 7 and the protective frame 8. A protective cover 27 is placed on the liquid storage tank 23. The diversion pipe 24 is arranged on one side of the liquid storage tank 23. A water pump 25 is arranged on the diversion pipe 24. Another diversion pipe 24 is connected to the water outlet of the water pump 25. A plurality of spray heads 26 are arranged on one side of the diversion pipe 24.

[0032] When the pills are being fed, the feeding belt 11 operates to uniformly convey and feed the pills after impurity removal. The staff starts the water pump 25, and the water pump 25 pumps the sugar solution in the liquid storage tank 23. The sugar solution is conveyed to multiple nozzles 26 along the diversion pipe 24, so that the sugar solution is uniformly sprayed on the surface of the pills in the form of a spray. The sugar solution covering the surface of the pills forms a protective layer after drying. The protective cover 27 prevents dust from depositing on the liquid storage tank 23.
