Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, and in particular to a capsule polishing machine. Background Technology

[0002] Capsule polishing machines are key downstream equipment used in the pharmaceutical and health product industries to remove dust from the surface of capsules and improve their appearance. Existing capsule polishing machines typically use brush polishing to clean dust from the capsule surface. However, this method is ineffective at cleaning heavy dust and capsule debris that settle to the bottom of the polishing cylinder due to their own weight. These deposits accumulate continuously in the dead corners at the bottom of the cylinder, forming a source of pollution and causing secondary pollution during the polishing process. There is an urgent need for a capsule polishing machine with better dust removal performance. Utility Model Content

[0003] The purpose of this invention is to provide a capsule polishing machine that addresses the shortcomings of existing technologies, eliminating the secondary pollution problem caused by dust accumulation at the bottom in traditional equipment, and significantly improving the final polishing cleanliness of capsules and the consistency of product quality.

[0005] A further improvement to the above solution is that the first dust cleaning component includes a vacuum cleaner, a dust collection pipe, and a negative pressure suction port. The vacuum cleaner is mounted on the frame, the outlet of the dust collection pipe is connected to the inlet of the vacuum cleaner, the inlet of the dust collection pipe is connected to the negative pressure suction port, and the negative pressure suction port is located on the side wall of the polishing cylinder.

[0006] A further improvement to the above solution is that the second cleaning component includes an airflow distribution pipe and an air pump. The airflow distribution pipe is located at the bottom of the polishing cylinder and is equipped with a micro-airflow nozzle. The air pump is located on the frame and the inlet of the airflow distribution pipe is connected to the outlet of the air pump.

[0007] A further improvement to the above scheme is that a plurality of micro-airflow nozzles are provided, and the plurality of micro-airflow nozzles are evenly and obliquely arranged on the side wall of the airflow distribution pipe along the circumferential direction, with the outlet of the micro-airflow nozzles facing the interior of the polishing cylinder.

[0008] A further improvement to the above solution is that a capsule barrier mesh is provided on the negative pressure dust suction port, and the capsule barrier mesh is provided with a number of through holes with a diameter smaller than that of the capsule.

[0009] A further improvement to the above solution is that the polishing mechanism includes a stirring shaft rotatably disposed inside the polishing cylinder, spiral stirring blades disposed on the stirring shaft, and a stirring drive motor for driving the stirring shaft to rotate.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings, such as... Figure 1-3 As shown, this utility model provides a capsule polishing machine, including a frame 1, and further comprising: Polishing cylinder 2 is mounted on frame 1; The feed pipe 21 is connected to the top of the polishing cylinder 2; The discharge pipe 22 is connected to the bottom of the polishing cylinder 2; Polishing mechanism 3, installed in polishing cylinder 2, is used to polish capsules; The dust cleaning mechanism 4, mounted on the frame 1, is used for dust cleaning. The dust cleaning mechanism 4 includes a first dust cleaning component 41 for cleaning floating dust and a second dust cleaning component 42 for cleaning settled dust. By setting up the first dust cleaning component 41 and the second dust cleaning component 42 to cooperate with each other, the dust in different states generated during the polishing process can be cleaned in a targeted manner. The first dust cleaning component 41 is responsible for capturing light floating dust to prevent it from polluting the environment and air, while the second dust cleaning component 42 is specifically for heavy dust and debris deposited at the bottom. This forms a three-dimensional, dead-angle-free dust control system inside the polishing cylinder 2. The two cleaning components work together to fundamentally eliminate the secondary pollution problem caused by dust accumulation at the bottom in traditional equipment, and significantly improve the final polishing cleanliness of the capsule and the consistency of product quality.

[0017] The first dust cleaning component 41 of this utility model includes a vacuum cleaner 411, a dust collection pipe 412, and a negative pressure suction port 413. The vacuum cleaner 411 is mounted on the frame 1. The outlet of the dust collection pipe 412 is connected to the inlet of the vacuum cleaner 411, and the inlet of the dust collection pipe 412 is connected to the negative pressure suction port 413. The negative pressure suction port 413 is located on the side wall of the polishing cylinder 2. Through the negative pressure system composed of the vacuum cleaner 411, the dust collection pipe 412, and the negative pressure suction port 413, a stable directional airflow can be continuously generated inside the polishing cylinder 2, so that the light dust generated during the polishing process is captured and removed in time before it settles. The cleaning process is proactive and efficient. The suction port is directly set on the side wall of the polishing cylinder 2, which is a reasonable position and can effectively cover the main area where dust is raised, ensuring a high capture rate.

[0018] The second cleaning component of this utility model includes an airflow distribution pipe 421 and an air pump 422. The airflow distribution pipe 421 is located at the bottom of the polishing cylinder 2 and is equipped with a micro-airflow nozzle 423. The air pump 422 is located on the frame 1. The inlet of the airflow distribution pipe 421 is connected to the outlet of the air pump 422. By using the combination of the airflow distribution pipe 421 and the air pump 422, the controlled micro-airflow is used to lift the settled dust from the bottom and then suck it away by the negative pressure suction port 413 of the first dust cleaning component 41. This achieves a precise coordination between "dust lifting" and "dust collection", completely avoiding the need to open a physical dust outlet at the bottom of the polishing cylinder 2. This eliminates the risk of capsules or capsule fragments being accidentally discharged from the bottom dust cleaning channel, ensuring that the discharge pipe 22 is dedicated to the conveying of qualified capsules, and greatly improving the stability of equipment operation and the purity of the output.

[0019] This utility model has several micro-airflow nozzles 423, which are evenly and circumferentially inclined on the side wall of the airflow distribution pipe 421. The outlet of the micro-airflow nozzles 423 faces the inside of the polishing cylinder 2. The evenly and circumferentially inclined micro-airflow nozzles 423 can form a comprehensive flow field at the bottom of the polishing cylinder 2. The inclined arrangement makes the airflow not only have an upward dust component, but also a tangential component, which helps to form a weak vortex at the bottom, thereby rolling up the dust at various locations and guiding it to the negative pressure dust suction port 413 on the side wall, avoiding local cleaning dead corners.

[0020] The negative pressure suction port 413 of this utility model is provided with a capsule blocking net 414. The capsule blocking net 414 is provided with a number of through holes 4141 with a diameter smaller than that of the capsule. The capsule blocking net 414 acts as a physical barrier. The diameter of the through holes 4141 on it is precisely designed to ensure that dust can pass through, but can effectively block complete capsules or even larger capsule fragments. This prevents the capsule from being accidentally sucked into the suction port under the action of suction negative pressure, thereby avoiding pipe blockage, capsule damage or even vacuum cleaner 411 malfunction.

[0021] The polishing mechanism 3 of this utility model includes a stirring shaft 31 rotatably disposed within a polishing cylinder 2, spiral stirring blades 32 disposed on the stirring shaft 31, and a stirring drive motor 33 for driving the stirring shaft 31 to rotate. The stirring drive motor 33 is disposed at the top of the polishing cylinder 2, and its power output end is connected to the stirring shaft 31. The power output end of the stirring drive motor 33 is connected to the stirring shaft 31 via a coupling 34. By directly driving the stirring shaft 31 through the coupling 34, the weight and vibration of the motor are borne by the frame 1 and do not directly act on the polishing cylinder 2, ensuring stable operation. The spiral stirring blades 32 not only effectively agitate and polish the capsules but also, to a certain extent, axially push the capsules, assisting their movement from the inlet to the outlet, thus integrating polishing and conveying functions.

[0022] Working principle: During operation, the capsule to be polished enters the polishing cylinder 2 through the top feed pipe 21. The stirring drive motor 33, located at the top of the polishing cylinder 2, drives the stirring shaft 31 to rotate via the coupling 34. This drives the spiral stirring blades 32 to uniformly stir and polish the capsule while slowly pushing it axially towards the bottom discharge pipe 22. The dust generated during the polishing process is divided into two categories for treatment: the first dust cleaning component 41 continuously sucks away the light floating dust suspended in the air through the negative pressure suction port 413 located on the side wall of the polishing cylinder 2 under the negative pressure generated by the vacuum cleaner 411; at the same time, the second dust cleaning component 42 located at the bottom of the polishing cylinder 2 starts to work. The air pump 422 delivers airflow to the airflow distribution pipe 421, and sprays gas jets into the cylinder through the micro-airflow nozzles 423 that are evenly arranged along the circumferential angle. These jets form a rotating airflow field at the bottom, which fully lifts the settled heavy dust, causing it to re-enter a suspended state and then be captured by the adjacent negative pressure suction port 413, forming a complete dust cleaning closed loop. Throughout the entire operation, the capsule barrier mesh 414 at the negative pressure dust suction port 413, with its precisely designed mesh structure, ensures that only dust can pass through, while the intact capsule is effectively blocked, preventing accidental aspiration of the capsule. The quick-release clamp structure used at each pipe connection point allows the equipment to be quickly disassembled when cleaning and maintenance are required, achieving thorough cleaning of the internal structure.

[0023] Of course, the above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
