A cihang capsule canning equipment

Abstract

The application belongs to the technical field of medicine granule canning, and particularly relates to a Cihang capsule canning equipment, which comprises a conveying device, a poking disc, a granule counting device, a discharging pipe, a discharging end, a fixed shell, a third motor and a second motor. The equipment designed in the application increases a blowing link in the canning process, reduces the canning time of medicines, reduces the waiting time required for canning, and correspondingly reduces the arrangement gap between adjacent medicine bottles. Such design can arrange more medicine bottles in an equal transportation distance, and improves the canning efficiency of the medicine bottles. Although the wool layer has a deceleration and buffering effect on the medicines, the wool layer section is much smaller than the medicine blowing and accelerating section. Therefore, although the tablet is decelerated by the wool layer and the canning time is increased, compared with the free-falling form of the medicine, the canning time of the application is relatively less, and the wool layer plays a protective role on the medicines.

Description

Technical Field

[0001] This invention belongs to the field of pharmaceutical granule filling technology, and particularly relates to a Cihang capsule filling device. Background Technology

[0002] After the capsules are counted by a capsule counter, they are filled into medicine bottles by a filling machine. To improve filling efficiency, equipment capable of filling multiple medicine bottles is used. For example... Figure 16 As shown, the device has four swing arms, each with a filling port. During the swinging motion, the medicine is filled into the bottles. Because filling takes time, the filling ports and bottles operate simultaneously for a certain period to ensure all medicine is filled. The filling principle in the diagram is as follows: Taking four groups of four bottles each as an example, the four groups of bottles move at a constant speed from left to right via a conveyor. Swing arm a fills the fourth bottle in each group, swing arm b fills the third bottle, swing arm c fills the second bottle, and swing arm d fills the first bottle. When the four groups of bottles pass through the four swing arms, a total of 16 bottles are filled. Each bottle undergoes a relatively long filling time to ensure sufficient filling time, but this reduces filling efficiency.

[0044] As shown in Figure 13 , 14 , the counting device 4 comprises a mounting block 43 and an air pump 29, wherein the upper end of the mounting block 43 has a plurality of feeding ports 31, and the upper end of each feeding port 31 is provided with a counting induction machine 40; the lower end of each feeding port 31 penetrates through the lower end surface of the mounting block 43 and has an air cavity 30 on the outside; Figure 15 As shown in Figure 15 , the lower end of each feeding port 31 is fixedly provided with an air pump 29 on the outside, and the air pump 29 is provided with an air suction port 45, an air blowing port and an air inlet 47; the air blowing port penetrates through the air cavity 30 at the lower end of the corresponding feeding port 31 and is connected with the inside of the feeding port 31; the air suction port is connected with the air cavity 30 at the lower end of the corresponding feeding port 31; Figure 14 As shown in Figure 14 , the lower end of the feeding port 31 of the counting device 4 is swingingly provided with a switch valve 28; the lower end of each feeding port 31 is fixedly provided with a fourth motor 42 on the outside, and the output shaft of the fourth motor 42 is drivingly connected with the swing shaft of the corresponding switch valve 28 through a plurality of fifth gears 44.

[0045] The counting induction machine 40 can record the amount of medicine filled from the feeding port 31, and when the amount of medicine meets the capping requirement, the fourth motor 42 is controlled to work to make the switch valve 28 open, so that the medicine in the feeding port 31 falls down. When the fourth motor 42 works, the fifth gear 44 drives the rotating shaft of the switch valve 28 to rotate, thereby controlling whether the switch valve 28 is opened or not.

[0046] The present application sets up the air pump 29 at the feed inlet 31, and the air pump 29 blows the air to the medicine in the downcomer 12 to increase the falling speed of the medicine; the air blown by the air pump 29 enters the first downcomer passage 33 in the downcomer 12 to blow the medicine in the downcomer 12, and part of the air flows upward from the first air flow passage 32 in the downcomer 12 when flowing downward along the downcomer passage of the downcomer 12, and the air is finally sucked into the air pump 29 from the air inlet 45 of the air pump 29, and because part of the air is discharged from the downcomer end 19, the present application additionally sets up an air inlet 47 on the air pump 29 to compensate the air lost from the downcomer end 19.
