Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of pill processing, and in particular relates to a pill sorting device. Background Art
[0002] Pills are a spherical drug preparation, mainly a traditional Chinese medicine preparation. Pills are a very common form of Chinese patent medicine. Unlike tablets, capsules, and liquid preparations, pills have the advantages of being easy to take, having a uniform particle size, and not easy to break.
[0003] At present, in the production process of pills, the drug ingredients are crushed (or extracted and concentrated) and mixed with drug excipients into agglomerates. After granulation by granulating equipment, the pills need to be screened. During the screening, the small-sized and broken pill fragments are sieved out to obtain qualified preparations with uniform particle size.
[0004] At present, the sorting is mainly done by sieving. The more common screening method is the swinging sieve, which uses the eccentric structure installed on the sieve to drive the sieve to do eccentric movement, and the pills are sorted in the process. However, the disadvantages of this overspeed method are very obvious, mainly because this screening method can only be applied to pill intermediates with higher dryness and greater particle strength.
[0005] As for pills with high viscosity and slightly high humidity (the dryness of pills varies mainly due to different processes, when sieving, the pills are in an undried state, and the pills on the sieve, especially the pills with high viscosity and high humidity, are easily deformed during sieving, which is reflected in the collapse of the spherical structure to form an oblate spherical shape.
[0006] Therefore, the use of rotary screening can not only maintain the particle shape of the pills, but also prevent the pills from being deformed after screening. However, during the screening process, since a large number of pills are added to the screen cylinder, the pills are easily pushed to one side of the screen cylinder, and a large number of pills are not distributed in the sieve hole structure on the screen cylinder. Therefore, in actual processing, the head of the screen cylinder is facing up and the tail is facing down, but after the pills are added, a large number of pills roll directly to the tail of the cylinder, causing the pills to accumulate at the tail of the cylinder. The accumulation of pills not only makes the pills easy to be squeezed and deformed, but also leads to very low screening efficiency. Utility Model Content
[0007] Based on the above background, the purpose of the utility model is to provide a pill sorting device.
[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0043] Example 1
[0044] like Figure 1-5 As shown, a pill sorting device includes a sorting mechanism, which includes a sorting cylinder 1; similar to the prior art, the sorting cylinder 1 is provided with a plurality of sorting sieve holes 11, the sorting mechanism also includes a frame-type rack 3 rotatably connected to the sorting cylinder 1, and the sorting mechanism also includes a motor 2 (mounted on the frame-type rack 3 through a mounting seat) for driving the sorting cylinder 1 to rotate.
[0045] The specific method is as follows: an annular baffle plate 12 (used to prevent pills from escaping from the mouth of the sorting cylinder 1 ) is detachably installed at the front and rear barrel openings of the sorting cylinder 1 .
[0046] Specifically, the annular baffle plate 12 is connected with a driving arm plate 13 (the driving arm plate 13 is fixedly installed on the annular baffle plate 12 through a connecting rod), and the driving arm plate 13 is fixedly connected with a rotating shaft. According to the existing method, the rotating shaft is rotatably connected to the frame frame 3, specifically, through a bearing rotation connection method. The output shaft of the motor is installed on the rotating shaft, according to the existing method, such as through a connecting flange.
[0047] During operation, the motor 2 is turned on, and the pills are added into the sorting cylinder 1 to achieve screening of the pills in a rolling manner.
[0048] Example 2
[0049] like Figure 1-5 As shown, based on the structure of Example 1, in order to avoid excessive accumulation of pills on one side of the sorting cylinder 1 during rolling screening, resulting in serious extrusion deformation and low screening efficiency, the pill sorting device also includes a lifting mechanism for raising and lowering the end position of the sorting mechanism; when the pill material is added to the sorting cylinder 1, one end of the sorting cylinder 1 is raised or lowered by the lifting mechanism to promote uniform distribution of the pills in the sorting cylinder 1.
[0050] Specifically, the lifting mechanism includes an arc track 4 fixedly connected to the left and right sides of the frame frame 3; the specific method is: the left and right walls of the frame frame 3 are respectively welded with front and rear convex seats spaced apart, and the two ends of the arc track 4 are welded to the bottom of the convex seats.
[0051] Meanwhile, a track base 7 is supported at the bottom of each arc track 4 .
[0052] The arc track 4 is provided with an arc opening 41 , and the lifting mechanism further comprises a first cylinder 52 and a second cylinder 51 arranged on both sides of the arc track 4 ; specifically, the first cylinder 52 is at the rear side of the arc track 4 , and the second cylinder 51 is at the front side of the arc track 4 .
[0053] At the same time, a lifting structure for lifting the arc track 4 and a lowering structure for lowering the arc track 4 are fixedly connected to the piston rods of the first cylinder 52 and the second cylinder 51 respectively.
[0054] During operation, the rear end of the sorting cylinder 1-frame frame 3 is raised by the first cylinder 52, and the front end is lowered by the second cylinder 51. At this time, the pills concentrated in the sorting cylinder 1 roll. By repeatedly raising and lowering the sorting cylinder 1, the easy rolling characteristics of the pills are utilized to evenly spread the concentrated pills.
[0055] Specifically, the lifting structure includes a lifting rod 521 fixedly connected to the piston rod of the first cylinder 52 , and the lifting rod 521 passes through the arc-shaped opening 41 ; a top seat B abutting against the bottom position of the arc-shaped track 4 is fixedly connected to the lifting rod 521 .

[0057] During operation, the first cylinder 52 and the second cylinder 51 cooperate with each other. When the first cylinder 52 lifts the lifting rod 521 and the seat B lifts the rear side of the arc track 4, the second cylinder 51 contracts, and the pressing rod 511 lowers the seat A to press the front side of the arc track 4. The two cooperate with each other to lift and lower the sorting cylinder 1. Then the cylinder is reset, and the sorting cylinder 1 is repeatedly "swung" in the above manner to promote uniform distribution of pills.
[0058] In the above process, the pressing rod 511 and the lifting rod 521 both slide relative to the arc-shaped opening 41 .
[0059] At the same time, in order to improve the stability of the arc track 4, the top of the track base 7 is fixedly connected with a plurality of limit rods 71 that penetrate the arc opening 41. During the turning process of the arc track 4, the limit rods 71 are limited in the arc opening 41 to avoid rolling over.
[0060] The cylinder barrels of the first cylinder 52 and the second cylinder 51 are respectively mounted at the bottom of the arc track 4 through cylinder barrel mounting plates.

The sieved pills are collected in the collection frame 6.
[0063] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
