Description

Technical Field

[0001] The utility model relates to the technical field of capsule production and manufacturing, and particularly relates to a capsule sorting device. Background Technique

[0002] As a common drug carrier, capsules need to go through strict manufacturing processes during production to ensure the quality and safety of products. The filling of capsules is a very crucial step, which directly affects the quality and efficacy of the final products. However, during the production process of capsules, due to various reasons, there may sometimes be empty capsules, that is, there is no drug filled in the capsule shell. To ensure the quality of drugs and the safety of consumers, it is particularly important to effectively sort the capsules.

[0003] In large-scale capsule production, currently, weighing sorters or vision-based sorting devices are often used to sort empty capsules. Such devices can accurately separate empty capsules, but they have high requirements for the accuracy of weight sensors and special cameras, and need to be matched with corresponding control systems. Therefore, the cost is relatively high, and it is difficult for small-scale capsule manufacturers to bear the purchase cost of such devices.

[0004] Therefore, this application specifically proposes a capsule sorting device to solve the above technical problems. Content of the Utility Model

[0005] The main purpose of the utility model is to solve the above deficiencies, and provide a capsule sorting device with a simple structure, which can reduce the manufacturing cost on the basis of ensuring the sorting effect.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A capsule sorting device includes: a chute, which is inclined and arranged on a bracket, and a feed hopper is fixedly arranged at the upward inclined end of the chute; a diversion assembly, which is arranged at the discharge chute opening at the downward inclined end of the chute, and is used for diverting the capsules so that the capsules can slide out of the chute side by side; a screening and moving assembly, which is arranged on the bracket and is used for driving the chute to make a reciprocating screening and moving motion along the direction perpendicular to the sliding direction of the material; a sorting assembly, which is arranged at the discharge chute opening at the downward inclined end of the chute, and includes a blowing assembly arranged below the discharge chute opening and an empty capsule collection assembly arranged above the blowing assembly.

[0008] Furthermore, the diversion assembly includes a plurality of limiting blocks uniformly arranged at the discharge chute opening and a baffle fixedly arranged between the inner cavity side walls of the chute and abutting against the top surfaces of the plurality of limiting blocks. The distance between adjacent limiting blocks is greater than the diameter of a single capsule, and the height of the limiting block is greater than the diameter of a single capsule but less than twice the diameter of a single capsule.

[0009] Further, one end of the limiting block facing the feed hopper is arranged in a conical shape.

[0010] Further, the air blowing assembly includes a blowing nozzle fixedly arranged at the discharge slot of the sliding groove and a blower communicated with the blowing nozzle, and the opening end of the blowing nozzle faces vertically upward.

[0011] Further, a falling prevention net is arranged at the opening end of the blowing nozzle.

[0012] Further, the empty capsule collecting assembly includes a collecting hopper arranged above the blowing nozzle and a collecting box communicated with the collecting hopper.

[0013] Further, both sides of the blowing nozzle and the collecting hopper are blocked by side sealing plates.

[0014] Further, the screening and moving assembly includes guide rods symmetrically arranged on both sides of the sliding groove and passing through the bracket, a connecting block fixedly arranged at the bottom of the sliding groove, a motor fixedly arranged on the bracket, a crankshaft drivingly connected to the output end of the motor, and a connecting rod with one end hinged to the connecting rod journal of the crankshaft and the other end hinged to the connecting block, and the axial direction of the connecting rod journal of the crankshaft is perpendicular to the axial direction of the guide rod.

[0015] Further, linear bearings are fixedly arranged at the corresponding positions of the bracket and the guide rods, and the guide rods are arranged in the linear bearings.

[0016] The beneficial effects of the present utility model are embodied in:

[0017] In the present utility model, a sliding groove is obliquely arranged on the bracket, and a guiding assembly is arranged at the discharge slot of the sliding groove. The capsules sliding down from the sliding groove can slide out side by side from the discharge slot of the sliding groove after being limited by the guiding assembly, avoiding the capsules from sliding out of the sliding groove overlapping with each other and affecting the sorting effect of the subsequent sorting assembly; a sorting assembly composed of a mutually cooperating air blowing assembly and an empty capsule collecting assembly is arranged at the discharge slot of the sliding groove. By using the weight difference between the empty capsules and the normally filled capsules, the air blowing assembly is used to blow the empty capsules into the empty capsule collecting assembly to realize the sorting of the capsules; a screening and moving assembly is arranged to drive the sliding groove to reciprocate left and right, thereby screening the capsules in the sliding groove so that they can more easily enter the guiding assembly and will not be blocked due to a large accumulation at the guiding assembly.

Detailed implementation manners

[0024] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] As Figures 1-4 shown, the present utility model provides a capsule sorting device, including:

[0026] A chute 1, which is inclined and arranged on the bracket 2, and a feed hopper 3 is fixedly arranged at the upwardly inclined end of the chute 1;

[0027] A diversion component 4, which is arranged at the discharge chute opening at the downwardly inclined end of the chute 1, and is used for guiding the capsules so that the capsules can slide out of the chute 1 side by side;

[0028] A screening moving component 5, which is arranged on the bracket 2 and is used for driving the chute 1 to perform a reciprocating screening movement in a direction perpendicular to the sliding direction of the material;

[0029] A sorting component 6, which is arranged at the discharge chute opening at the downwardly inclined end of the chute 1, and includes a blowing component 61 arranged below the discharge chute opening and an empty capsule collection component 62 arranged above the blowing component 61.

[0030] During use, the capsules to be sorted are input into the device from the feed hopper 3. Under the action of their own gravity, the capsules slide downward along the chute 1 and, under the guiding action of the guiding component 4, slide out side by side from the discharge chute opening of the chute 1. The function of arranging the screening component 5 here is to drive the chute 1 to reciprocate left and right by means of the screening component 5, thereby screening the capsules in the chute 1 so that they can more easily enter the guiding component 4 without being blocked due to a large accumulation at the guiding component 4. When the capsules slide out of the chute 1, they are subjected to the vertically upward blowing force of the blowing component 61. The lighter empty capsules are blown into the empty capsule collection component 62, while the normally filled capsules, under the action of their own gravity and sliding inertia, pass through the area covered by the blowing component 61 and are discharged from the device, thus completing the sorting of the capsules.

[0031] In one embodiment, the guiding component 4 includes a plurality of limiting blocks 41 uniformly arranged at the discharge chute opening and a baffle 42 fixedly arranged between the inner cavity side walls of the chute 1 and abutting against the top surfaces of the plurality of limiting blocks 41. The distance between adjacent limiting blocks 41 is greater than the diameter of a single capsule, and the height of the limiting blocks 41 is greater than the diameter of a single capsule but less than twice the diameter of a single capsule.

[0032] With such a design, under the combined limiting action of the limiting blocks 41 and the baffle 42, the capsules can only slide out side by side from the discharge chute opening of the chute 1 and cannot overlap vertically and slide out of the chute 1, thereby avoiding the influence of mutual overlap on the sorting effect of the blowing component 61 when the capsules pass through the area covered by the blowing component 61.

[0033] In one embodiment, one end of the limiting block 41 facing the feed hopper 3 is arranged in a conical shape.

[0034] With such a design, the capsules can more easily enter the gap between the two limiting blocks 41, improving the guiding efficiency.

[0035] In one embodiment, the blowing component 61 includes a blowing nozzle 611 fixedly arranged at the discharge chute opening of the chute 1 and a blower 612 communicated with the blowing nozzle 611. The opening end of the blowing nozzle 611 faces vertically upward. A anti-falling net 7 is arranged at the opening end of the blowing nozzle 611.

[0036] With such a design, the air blown by the blower 612 is conveyed through a pipeline to the blowing nozzle 611. The blowing nozzle 611 blows air on the capsules passing through its covered area and applies a vertically upward force, enabling the lighter empty capsules to be blown into the empty capsule collection component 62, while the anti-falling net 7 can prevent the normally filled capsules from accidentally falling into the blowing nozzle 611.

[0037] In one embodiment, the empty capsule collection component 62 includes an aggregate hopper 621 arranged above the blowing nozzle 611 and a collection box 622 communicated with the aggregate hopper 621.

[0038] With this design, the empty capsules blown away by the blowing assembly 61 are collected in the collecting hopper 621 and then further blown into the collecting box 622 under the wind pressure of the blowing assembly 61 for further processing.

[0039] In one embodiment, both sides of the blowing nozzle 611 and the collecting hopper 621 are blocked by side sealing plates 8 .

[0040] This design allows the air blown out by the blowing nozzle 611 to be more concentrated, and can blow away the empty capsules more effectively. It also prevents the blown empty capsules from flying out of the gaps on both sides of the blowing nozzle 611 and the collecting hopper 621, making it impossible to effectively collect the empty capsules.

[0041] In one embodiment, the screening assembly 5 includes a guide rod 51 symmetrically arranged on both sides of the slide 1 and passing through the bracket 2, a connecting block 52 fixedly arranged at the bottom of the slide 1, a motor 53 fixedly arranged on the bracket 2, a crankshaft 54 ​​transmission-connected to the output end of the motor 53, and a connecting rod 55 hinged at one end to the connecting rod journal of the crankshaft 54 ​​and at the other end to the connecting block 52, and the axial direction of the connecting rod journal of the crankshaft 54 ​​is perpendicular to the axial direction of the guide rod 51.

[0042] With this design, after the motor 53 is started, it drives the crankshaft 54 ​​to rotate, and the crankshaft 54 ​​drives the connecting block 52 to reciprocate along the direction of the guide rod 51 through the connecting rod 55. Driven by the connecting block 52, the chute 1 also reciprocates along the direction of the guide rod 51, thereby achieving a screening effect on the capsules in the chute 1.

[0043] In one embodiment, a linear bearing 9 is fixedly provided at a position corresponding to the bracket 2 and the guide rod 51 , and the guide rod 51 passes through the linear bearing 9 .

[0044] This design reduces the sliding resistance between the guide rod 51 and the bracket 2, making the relative sliding between the two smoother.

[0045] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

[0046] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0047] In addition, "a plurality of" means two or more. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
