Furthermore, when the brush bristles contact the discharge screen, they clear any blockages, ensuring smooth material discharge after pulverization.

Description

Technical Field

[0001] This utility model relates to the field of pulverizing devices, specifically to a pulverizing device for granule production. Background Technology

[0002] Granules are a type of traditional Chinese medicine preparation. They are a new type of traditional Chinese medicine preparation made by extracting, concentrating, drying, and granulating Chinese medicinal herbs. They have the advantages of convenient administration, rapid absorption, and good efficacy. When preparing granules, it is necessary to select appropriate Chinese herbal medicines and excipients as raw materials and to process them by crushing and sieving.

[0003] The existing pulverizing equipment for granule production still has the following problems when in use: During the pulverizing process, the pulverized material is not convenient to be discharged in advance. It is necessary to wait until the material inside the pulverizing barrel is completely pulverized before discharging it together. Moreover, it is not possible to continuously feed material during the pulverizing process and pulverize it together with the original material, which results in low pulverizing efficiency.

[0004] Therefore, it is necessary to invent a pulverizing device for granule production to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a pulverizing device for granule production, in order to solve the problem mentioned in the background art that the pulverized material is not convenient to be discharged in advance during the pulverizing process, and needs to be discharged together after the material inside the pulverizing barrel is completely pulverized. Furthermore, it is impossible to continuously feed material during the pulverizing process to pulverize it together with the original material, which leads to low pulverizing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a pulverizing device for granule production, comprising a pulverizing barrel, an inlet at the top of the pulverizing barrel, and a discharge screen fitted at the bottom of the pulverizing barrel. Support legs are fixedly installed at the bottom of the pulverizing barrel, and a base plate is fixedly installed at the bottom of the support legs. The base plate is fixedly connected to a motor base, and a motor is fitted inside the motor base. A drive shaft is driven by the motor output shaft, and the drive shaft is parallel and linked to a linkage shaft via a gear set. Pulverizing blades are fixedly mounted on the outer rings of both the drive shaft and the linkage shaft. A short shaft rotatably connected to the end wall of the pulverizing barrel is driven by a belt, and the short shaft is also driven by a stirring and unblocking assembly.

[0007] Preferably, the gear set consists of two meshing gears, and the two gears are respectively fixedly mounted on the outer rings of the drive shaft and the linkage shaft. The outer rings of the drive shaft and the linkage shaft are rotatably connected to the crushing barrel through bearings, so that when the motor drives the drive shaft to rotate, the linkage shaft rotates synchronously in the opposite direction.

[0008] Preferably, the two sets of crushing blades are staggered and rotate in different directions. When the drive shaft rotates, the linkage shaft rotates synchronously in opposite directions, causing the two sets of crushing blades to rotate in different directions to crush the material.

[0009] Preferably, the agitation and unblocking assembly includes an arched frame fixedly connected to a short shaft, with the rods at both ends of the arched frame passing through a pre-reserved annular groove inside the crushing barrel and being inserted into an annular block rotatably connected inside the annular groove. The rods at both ends of the arched frame extend into the inside of the crushing barrel, and the rods at both ends of the arched frame are fixedly connected to a brush. The bristles of the brush are in contact with the inner wall of the crushing barrel and the discharge screen. In this way, when the crushing blades rotate to perform crushing, the brush rotates synchronously and agitates the material inside the crushing barrel, ensuring circulating crushing and making the crushing efficiency higher.

[0010] Preferably, the inner wall of the annular groove is attached to the outer wall of the annular block and the outer walls of the two sections of the arched frame to achieve a rotatable connection, ensuring the stability of the arched frame's rotation.

[0011] Preferably, the stirring and unblocking assembly further includes connecting rods fixedly connected to the inner walls of both ends of the crushing barrel, and the connecting rods do not contact the crushing blades and brushes, ensuring that the end blocks of the crushing barrel with annular grooves and cut by the annular grooves do not fall off.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention uses a motor to drive the drive shaft to rotate, and under the linkage of the gear set, the linkage shaft rotates synchronously in opposite directions, thereby driving two sets of crushing blades to rotate in different directions to crush the material. At the same time, the drive shaft rotates, and through the belt, it drives the short shaft to rotate, which in turn drives the arched frame to rotate, causing the brush to rotate synchronously. The synchronous rotation of the brush allows the brush rods to tumble and mix the material inside the crushing barrel, ensuring circulating crushing and making the crushing efficiency higher. At the same time, when the brush bristles come into contact with the discharge screen, they clear the blockage of the discharge screen, ensuring smooth discharge of the crushed material.

[0017] This utility model provides, for example Figure 1-4 The pulverizing device shown includes a pulverizing barrel 1, a feed inlet 2 at the top of the pulverizing barrel 1, and a discharge screen 3 fitted into the bottom of the pulverizing barrel 1. A support leg 4 is fixedly installed at the bottom of the pulverizing barrel 1, and a base plate 5 is fixedly installed at the bottom of the support leg 4. The base plate 5 is fixedly connected to a motor base 6. A motor 7 is fitted inside the motor base 6, and a drive shaft 8 is driven by the output shaft of the motor 7. The drive shaft 8 is parallel and linked to a linkage shaft 10 through a gear set 9. Pulverizing blades 11 are fixedly mounted on the outer ring of both the drive shaft 8 and the linkage shaft 10. A short shaft 13 rotatably connected to the end wall of the pulverizing barrel 1 is driven by a belt 12. The short shaft 13 is also driven by a stirring and unblocking assembly 14.

[0018] When the motor 7 drives the drive shaft 8 to rotate, the linkage shaft 10 rotates synchronously in opposite directions under the linkage of the gear set 9. This drives the two sets of crushing blades 11 to rotate in different directions to crush the material. At the same time, the drive shaft 8 rotates, which drives the short shaft 13 to rotate through the belt 12. Consequently, the arched frame 141 rotates, causing the brush 142 to rotate synchronously. The synchronous rotation of the brush 142 allows the brush rods of the brush 142 to stir the material inside the crushing barrel 1, ensuring circulating crushing and making the crushing efficiency higher. At the same time, when the bristles of the brush 142 come into contact with the discharge screen 3, they clear the blockage of the discharge screen 3, ensuring smooth discharge of the crushed material.

[0019] The gear set 9 consists of two meshing gears, which are respectively fixedly mounted on the outer rings of the drive shaft 8 and the linkage shaft 10. The outer rings of the drive shaft 8 and the linkage shaft 10 are rotatably connected to the crushing barrel 1 through bearings, so that when the motor 7 drives the drive shaft 8 to rotate, the linkage shaft 10 rotates synchronously in the opposite direction.

[0020] The two sets of crushing blades 11 are staggered and rotate in different directions.

[0021] When the drive shaft 8 rotates, the linkage shaft 10 rotates synchronously in the opposite direction, driving the two sets of crushing blades 11 to rotate in different directions to crush the material. The material that meets the feeding standard will be discharged through the discharge screen 3.

[0022] The mixing and unblocking assembly 14 includes an arched frame 141 fixedly connected to a short shaft 13. The rods at both ends of the arched frame 141 pass through the annular groove 144 reserved inside the crushing barrel 1 and are inserted into the annular block 143 rotatably connected inside the annular groove 144. The rods at both ends of the arched frame 141 extend into the inside of the crushing barrel 1, and the rods at both ends of the arched frame 141 are fixedly connected to a brush 142. The bristles of the brush 142 are in contact with the inner wall of the crushing barrel 1 and the discharge screen 3. The inner wall of the annular groove 144, the outer wall of the annular block 143, and the outer wall of the two rods of the arched frame 141 are attached to each other and rotatably connected.

[0023] When the drive shaft 8 rotates, the belt 12 drives the short shaft 13 to rotate, causing the arched frame 141, which is fixedly connected to the short shaft 13, to rotate. The brush 142 rotates synchronously, and the brush rods of the brush 142 can agitate the material inside the crushing barrel 1, ensuring circulating crushing and making the crushing efficiency higher. At the same time, when the bristles of the brush 142 come into contact with the discharge screen 3, they clear the blockage of the discharge screen 3. A collection bag is connected to the outside of the discharge screen 3 to ensure that the crushed material does not scatter during discharge.

[0024] The mixing and unblocking assembly 14 also includes a connecting rod 145 fixedly connected to the inner walls of both ends of the crushing barrel 1, and the connecting rod 145 does not contact the crushing blade 11 and the brush 142, ensuring that the end blocks of the crushing barrel 1 with the annular groove 144 and cut by the annular groove 144 do not fall off.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
