Description

Technical Field

[0001] This utility model relates to the field of pulverizing equipment technology, and in particular to a pulverizing device for tablet preparation. Background Technology

[0002] Tablets are solid dosage forms that are compressed into tablets or irregularly shaped tablets after the drug and excipients are uniformly mixed. Tablets are mainly oral tablets, but there are also lozenges, sublingual tablets, oral patches, chewable tablets, dispersible tablets, effervescent tablets, vaginal tablets, immediate-release or sustained-release or controlled-release tablets, and enteric-coated tablets, etc. The production and processing of tablets involves a pulverization process, and in current technology, pulverizers are usually used to pulverize tablets.

[0003] In the prior art, such as the tablet pulverizer with publication number CN210613982U, a base plate is included. Support columns are fixedly connected to both sides of the top of the base plate. A support plate is fixedly connected to the top of each support column. A pulverizing device is fixedly connected to the top of the support plate. A feeding pipe is connected to the bottom of the pulverizing device, and the bottom of the feeding pipe extends through to the bottom of the support plate and is connected to a flexible hose. This invention utilizes the coordinated use of the feeding pipe, flexible hose, transmission box, motor, gears, toothed plate, sliding column, slider, triangular block, slide rail, pulley, and transmission column. The transmission column drives the flexible hose to sway left and right, achieving the effect of preventing feeding blockage. This tablet pulverizer solves the problem of existing pulverizers only being able to pulverize materials once, resulting in incomplete pulverization and easy blockage during feeding. This enhances the practicality and efficiency of the pulverizer.

[0004] However, existing pulverizers have some problems when applied to tablet production. Existing pulverizers achieve tablet pulverization through mechanical shearing. During the shearing and pulverization of tablet raw materials, the particle size distribution is relatively wide due to the shearing force, resulting in poor mixing uniformity, which is not conducive to subsequent processing and use.

[0005] Therefore, it is necessary to invent a pulverizing device for tablet preparation to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a pulverizing device for tablet preparation, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pulverizing device for tablet preparation, comprising a device housing, an end cap fixedly installed on the outer side of the device housing, a first liner fixedly installed on the inner side of the end cap, a second liner fixedly installed on the inner side wall of the device housing, annular liner fixedly installed on the side of the first and second liners that are close to each other, a plurality of annular liners being staggered, a plurality of pulverizing liners fixedly installed on the side of the first and second liners that are close to each other, both sides of the plurality of pulverizing liners being inclined, a guide plate installed between the first and second liners, a plurality of extension arms being installed around the outer side wall of the guide plate, extension blocks being fixedly installed on both sides of the plurality of extension arms, and the extension blocks being staggered with the annular liners, a plurality of distributing plates fixedly installed on the outer side of the guide plate, the plurality of distributing plates being funnel-shaped.

[0008] Preferably, a fixing block is fixedly installed in the middle of the side of the guide plate near the end cover, and the end of the fixing block near the end cover is designed as a hemispherical structure.

[0009] Preferably, the outer side wall of the fixing block is surrounded by multiple diversion plates, and all of the diversion plates are inclined structures.

[0010] Preferably, a feed conduit is fixedly installed on the middle of the outer side of the end cap, and the bottom end of the feed conduit corresponds to the fixing block.

[0011] Preferably, a feed hopper is fixedly installed at the top end of the feed conduit, and the feed hopper is designed as a funnel shape.

[0012] Preferably, a rotating shaft is rotatably mounted in the middle of the equipment housing via a bearing, and one end of the rotating shaft is fixedly connected to the middle of the guide plate.

[0013] Preferably, a bracket is fixedly installed at the bottom of the device housing, a motor is fixedly installed at the top of the bracket, and a transmission belt is installed between the output shaft and the rotating shaft of the motor.

[0014] The technical effects and advantages of this utility model are as follows:

[0015] 1. This utility model provides a first liner, a second liner, and an annular liner inside the equipment housing. The first and second liners form a chamber for pulverizing tablets. Multiple alternating annular liners form multiple channels within the chamber. The tablet raw material passes through these multiple channels sequentially during pulverization. The arrangement of these multiple channels restricts the particle size distribution of the pulverized tablet raw material, thereby ensuring that the pulverized tablet raw material can be fully mixed. Furthermore, by placing a pulverizing liner on the side where the first and second liners are close to each other, the tablet raw material collides with the pulverizing liner when passing through the multiple channels, thereby improving the pulverization effect of the tablet raw material.

[0016] 2. This utility model, by setting up a guide plate, provides rotational power to the tablet raw materials after they are fed into the equipment shell, thereby increasing the collision effect between the tablet raw materials and multiple sets of liners and ensuring the pulverization effect of the tablets. In addition, multiple sets of trumpet-shaped distribution plates are set on the outside of the guide plate. The distribution plates can guide the tablet raw materials to ensure that tablets of different particle sizes can enter the corresponding pulverization channels, thereby improving the pulverization effect of the device.

A transmission belt 18 is installed between the output shaft of the motor 17 and the rotating shaft 15. A pulley for cooperating with the transmission belt 18 is installed at one end of both the output shaft of the motor 17 and the rotating shaft 15. The above transmission method is a conventional means in the art and will not be described in detail here.

[0029] Working principle of this utility model:

[0030] In use, the end cap 2 is installed on the outside of the equipment housing 1 using bolts, clamps, and other fasteners. The end cap 2 and the equipment housing 1 form a chamber for crushing tablet raw materials. The tablet raw materials to be crushed are fed into the inside of the equipment housing 1 through the feed hopper 14 and the feed conduit 13. The tablet raw materials directly enter between the first liner plate 3 and the guide plate 7. The motor 17 is started, and the motor 17 drives the rotating shaft 15 and the guide plate 7 to rotate through the transmission belt 18. The guide plate 7 drives the tablet raw materials to move through the fixing block 11 and the guide plate 12 on its outer side, so that the tablet raw materials rotate at high speed between the first liner plate 3 and the guide plate 7. The high-speed rotating tablet raw materials collide with the annular liner plate 5 on the inner side of the first liner plate 3 and are crushed under the impact. The tablet raw materials are crushed to... After a certain period of time, the particle size of the tablet raw material is smaller than the gap between the multiple dispensing plates 10. At this time, the tablet raw material is guided by the dispensing plates 10 to the space between the second liner 4 and the guide plate 7 under the action of centrifugal force. Then the tablet raw material continues to rotate and collides with the inner wall of the second liner 4, and is further crushed. After the tablet raw material is crushed again, the particle size of the tablet raw material is small enough. Under the action of centrifugal force, the tablet raw material moves to the inner wall of the annular liner 5 on one side of the second liner 4. As the tablet raw material accumulates, some tablet raw material passes through the gap between the annular liner 5 on one side of the second liner 4 and the guide plate 7 and enters the space between the guide plate 7 and the first liner 3. At this time, the small-sized tablet raw material reaches the outer side of the annular liner 5 on one side of the first liner 3 and is stored on the outer side of the annular liner 5.

[0031] During the entire crushing process, the moving tablet raw material collides with the crushing liner 6, which intensifies the crushing particle size of the tablet raw material. At the same time, the first liner 3, the second liner 4, the annular liner 5, and the guide plate 7 form three sets of crushing spaces. Tablet raw materials crushed to different degrees are crushed in different crushing spaces. The tablet raw material in the smaller space has a smaller particle size dispersion during crushing. Therefore, the tablet raw material in the smaller space can be fully mixed after crushing, which is convenient for subsequent processing and use.

[0032] After the tablet raw material is crushed, the end cap 2 is separated from the equipment shell 1, and the crushed tablet raw material can be taken out.

[0033] It should be noted that the motor 17 in this embodiment adopts the corresponding structure in the prior art, and is equipped with a power supply and a controller.

[0034] It should be further noted that the structures in this embodiment that are in direct contact with the tablet raw materials, such as the first liner 3, the second liner 4, the annular liner 5, the crushing liner 6, and the guide plate 7, are all made of stainless steel to ensure that the tablet raw materials are not contaminated during the crushing process.

[0035] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
