Description

Technical Field

[0001] The utility model belongs to the technical field of solid granule screening, in particular to a medical solid granule screening device. Background Art

[0002] Granules refer to dry granular preparations with a certain particle size made by mixing raw materials and suitable excipients.

[0003] Some existing screening equipment can only screen out solid granules of two sizes, and the screening effect is poor, resulting in the presence of some solid granules of different sizes after screening. In addition, the existing screening equipment cannot control the feeding speed during screening. If more solid granules are added at one time, it will affect the screening effect. In view of this, we propose a screening equipment for pharmaceutical solid granules. Utility Model Content

[0004] The purpose of the utility model is to provide a medical solid granule screening device to solve the problems raised in the above background technology.

[0005] In view of this, the utility model provides a medical solid granule screening device, comprising:

[0006] An outer shell, a feed hopper is fixedly installed on the top of the outer shell, a discharge port connected to the outer shell feeding port is provided at the bottom of the inner cavity of the feed hopper, a slide groove is provided in the feed hopper and on one side of the discharge port, a baffle is slidably installed in the slide groove, a plurality of screening rods 1 and an inclined plate are fixedly installed in the outer shell and directly below the discharge port from top to bottom, a fixed plate 2 is fixedly installed in the outer shell and at the bottom of the tail end of the plurality of screening rods 1, a plurality of screening rods 2 are fixedly installed on one side of the fixed plate 2 and below the inclined plate, a fixed plate 1 is fixedly installed in the outer shell and at the bottom of the tail end of the plurality of screening rods 2, a collecting box 1 and a collecting box 3 are slidably installed in the outer shell and at a side away from the fixed plate 2 and the fixed plate 1, a collecting box 2 is slidably installed in the outer shell and between the fixed plate 2 and the fixed plate 1, and the inclined plate is located on one side of the fixed plate 2;

[0007] A driving assembly is located in the slide slot and is used to drive the baffle to move.

[0008] In the present technical solution, when in use, the staff puts the solid granules into the feed hopper, and then, through the provided driving assembly, the driving assembly drives the baffle to move, and the baffle will move toward the chute, so that the baffle moves to a suitable position, ensuring that the opening size of the discharge port can be controlled, and then, the discharge port will be opened, and under the action of gravity, the solid granules in the feed hopper will fall from the discharge port onto the several screening rods 1 in the shell, and then, under the action of gravity, the solid granules on the several screening rods 1 will move toward the direction of the collecting box 1, and in the process of displacement, some smaller solid granules will leak out from the several screening rods 1 and fall onto the inclined plate, and then, The larger solid granules remaining on the screening rods one will be displaced and fall into the collecting box one, and then the smaller solid granules falling on the inclined plate will be displaced under the action of gravity and fall onto the screening rods two, and then, during the displacement of the solid granules on the screening rods two, even finer solid granules will leak out from the screening rods two and fall into the collecting box two, and then, the medium-sized solid granules on the screening rods two will be displaced on the screening rods two and fall into the collecting box three, so that the three sizes of solid granules can be collected, ensuring that the solid granules in each package are of uniform size and more accurate in weight when they are packaged.

[0009] In the above technical solution, further, the driving component includes:

[0010] A threaded rod is rotatably mounted in the slide groove, and one end of the threaded rod extends into the baffle, and the other end of the threaded rod passes through one side of the slide groove and extends to the outside, and a rocker is fixedly mounted on the other end of the threaded rod.

[0011] In this technical solution, when screening, the staff can turn the rocker on the threaded rod by hand and make it drive the threaded rod to rotate. Then, under the action of the thread, the threaded rod will drive the baffle to move, and the baffle will move toward the slide groove, so that the baffle moves to the appropriate position, ensuring that the opening size of the discharge port can be controlled.

[0012] In the above technical solution, further, the threaded rod is threadedly connected to the baffle.

[0013] In this technical solution, under the action of the thread, the baffle can be driven to move when the threaded rod rotates.

[0014] In the above technical solution, further, the distance between the two screening rods 1 is greater than the distance between the two screening rods 2, and a plurality of screening rods 1 and a plurality of screening rods 2 are all inclined structures, and the inclination angles of the plurality of screening rods 1 and the plurality of screening rods 2 are opposite.

[0015] In the technical solution, it is ensured that the plurality of screening rods 1 and 2 can screen out solid granules of different sizes, and, under the action of gravity, it is ensured that the solid granules can be displaced on the plurality of screening rods 1 and 2.

[0016] In the above technical solution, further, the bottom of the inner cavity of the feed hopper is an inclined structure.

[0017] In this technical solution, it is ensured that the solid granules in the inner cavity of the feed hopper can move toward the discharge port under the action of gravity.

[0018] In the above technical solution, further, the second collecting box is located directly below the plurality of second screening rods.

[0019] In this technical solution, it is ensured that the solid granules leaking from the plurality of screening rods 2 can fall into the collecting box 2.

[0020] The beneficial effects of the utility model are:

[0021] The pharmaceutical solid granule screening equipment ensures that the feeding speed can be controlled through the cooperation between the arranged feed hopper, the discharge port, the chute, the baffle, a plurality of screening rods 1, the inclined plate, the screening rod 2 and the driving assembly, and avoids the influence of too much solid granules added at one time on the screening effect. In addition, the overall device can screen out solid granules of three sizes, and the screening effect is better, so that the size of the solid granules in each size is more uniform.
