Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical production technology, and in particular relates to a pulverizer for pharmaceutical production and processing. Background Technology

[0002] Pulverizers are indispensable equipment in the pharmaceutical industry, responsible for crushing raw materials into suitable particle sizes to meet the needs of subsequent production processes.

[0003] Existing pharmaceutical pulverizers typically require materials to be placed in a pulverizing chamber and pulverized by pulverizing blades. This method results in a large number of particles remaining in the pulverized powder, leading to poor pulverization results, requiring multiple rework processes, reducing pulverization efficiency, and consuming a significant amount of time waiting for pulverization. Therefore, we propose a pulverizer for pharmaceutical production and processing. Utility Model Content

[0004] The purpose of this invention is to provide a pulverizer for pharmaceutical production and processing. By setting up a grinding assembly, specifically, after the material enters the pulverizing chamber, the crushing blade and the fixed rod work together to crush the material. The crushed material leaks out from the conical ring and is guided to the side of the grinding roller. Subsequently, the grinding roller grinds the material into powder by cooperating with the bottom of the pulverizing chamber. This method can improve the pulverizing effect, significantly reduce particle mixing, eliminate the need for multiple rework processes, and improve work efficiency. It solves the problem that existing pharmaceutical pulverizers typically use crushing blades to pulverize materials, which not only consumes a lot of time waiting for pulverization but also results in a large number of particles remaining in the pulverized material, leading to poor pulverizing effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a pulverizer for pharmaceutical production and processing, comprising a shell, a feed hopper fixedly connected to the top of the shell, a pulverizing chamber disposed inside the shell, a support plate fixedly connected to the outer side of the pulverizing chamber, the outer side of the support plate being fixedly connected to the inner wall of the shell, a crushing assembly disposed inside the pulverizing chamber, the crushing assembly including a rotating rod, a plurality of crushing blades fixedly connected to the outer surface of the rotating rod, a plurality of fixing rods fixedly connected to the inner wall of the pulverizing chamber, a conical ring fixedly connected to the inner wall of the pulverizing chamber, and a grinding assembly disposed at the bottom of the inner wall of the pulverizing chamber, the grinding assembly including a grinding roller, both the bottom conical surface of the grinding roller and the bottom conical surface of the inner wall of the pulverizing chamber being provided with... The grinding roller has a grinding protrusion, and a connecting rod is fixedly connected to the bottom of the grinding roller. A support block is fixedly connected to the left side of the outer shell, and a first motor is fixedly connected to the bottom of the support block. A first pulley is fixedly connected to the top output end of the first motor and the bottom of the connecting rod. The two first pulleys are connected by belt drive. After the material enters the crushing box, the crushing blade and the fixed rod cooperate to crush the material. The crushed material leaks out from the conical ring and is guided to the side of the grinding roller. Then, the grinding roller grinds the material into powder by cooperating with the bottom of the crushing box. This method can improve the crushing effect, greatly reduce the occurrence of particle mixing, eliminate the need for multiple rework, and improve work efficiency.

[0007] Furthermore, a support base is fixedly connected to the top of the outer shell, and a second motor is fixedly connected to the top of the support base. A second pulley is fixedly connected to the bottom output end of the second motor and the top of the rotating rod. The two second pulleys are connected by belt drive. The top of the rotating rod passes through the outer shell and extends to the outside. The rotating rod is rotatably connected to the outer shell. By starting the second motor, the second pulley on the right side is driven to rotate, and the second pulley on the left side is driven to rotate by belt drive. At this time, the rotating rod drives the crushing blade to rotate together, so that the crushing blade cooperates with the fixed rod to facilitate the crushing of materials.

[0008] Furthermore, a sieve plate is provided below the crushing box, extending to the outer side of the outer shell on the right side. A protrusion is fixedly connected to the inner wall of the sieve plate, and an inclined plate is fixedly connected to the bottom of the sieve plate. Several support rods are fixedly connected to both the front and back of the sieve plate, with the side of the support rod away from the sieve plate fixedly connected to the inner wall of the outer shell. A collection box is provided below the sieve plate, and the collection box is inserted into the outer shell. The sieve plate is inclined. After the crushed powder is discharged onto the sieve plate, it is filtered by the sieve plate and collected in the collection box. The remaining particles are discharged from the right side of the sieve plate. The protrusion serves to provide some shielding, allowing the material to be filtered better and reducing the amount of powder discharged directly from the right side of the sieve plate.

[0009] Furthermore, several collision blocks are fixedly connected to the outer surface of the connecting rod, a moving block is provided on the left side of the connecting rod, an electric push rod is fixedly connected to the left side of the inner wall of the outer shell, the right output end of the electric push rod is fixedly connected to the left side of the moving block, a collision rod is slidably connected inside the moving block, and a spring is sleeved on the outside of the collision rod; after the crushing work is completed, the electric push rod is started to drive the moving block to the right, so that the collision rod moves to the position of the collision block. At this time, when the connecting rod is rotating, the collision block will rotate with it and come into contact with the collision rod. This process is repeated, so that the connecting rod and the grinding roller can produce a vibration effect, cleaning the attached powder, reducing the residue, and facilitating the next crushing work.

[0010] Furthermore, the right side of the collision rod is hemispherical, and the collision block is arc-shaped. The right side of the collision rod passes through the moving block and extends to the outside. The left side of the spring is fixedly connected to the outside of the collision rod, and the right side of the collision rod is fixedly connected to the inner wall of the moving block. After the collision rod contacts the collision block, it will be pushed and the spring will be stretched. At this time, the collision block will pass smoothly through the collision rod, so as not to affect the rotation of the collision block.

[0011] Furthermore, a circular hole is provided at the bottom of the rotating rod, and a stabilizing rod is fixedly connected to the top of the grinding roller. The stabilizing rod is set in the circular hole at the bottom of the rotating rod and is rotatably connected to the rotating rod. The top of the grinding roller rotates in the rotating rod through the stabilizing rod, which can improve the stability of both the grinding roller and the rotating rod at the same time without affecting their rotation.

[0012] This utility model has the following beneficial effects:

[0013] This utility model, through the setting of a grinding component, specifically, after the material enters the crushing chamber, the crushing blades and...

[0014] The fixed rod crushes the material, which then leaks out from the conical ring and is guided to the side of the grinding roller. The grinding roller then grinds the material into powder by cooperating with the bottom of the crushing box. This method can improve the crushing effect, greatly reduce the occurrence of particle mixing, eliminate the need for multiple rework, and improve work efficiency.

Grinding ridges are provided on the bottom conical surface of the inner wall of the box 13. A connecting rod 152 is fixedly connected to the bottom of the grinding roller 151. A support block 16 is fixedly connected to the left side of the outer shell 1. A first motor 161 is fixedly connected to the bottom of the support block 16.

After the material enters the crushing box 13, the crushing blade 142 and the fixed rod 143 cooperate to crush the material. The crushed material leaks out from the conical ring 132 and is guided to the side of the grinding roller 151. Then, the grinding roller 151 grinds the material into powder by cooperating with the bottom of the crushing box 13. This method can improve the crushing effect, greatly reduce the occurrence of particle mixing, eliminate the need for multiple rework, and improve work efficiency.

[0026] A support base 12 is fixedly connected to the top of the outer casing 1. A second motor 121 is fixedly connected to the top of the support base 12.

The collection box 3 is inserted into the outer shell 1. The sieve plate 2 is inclined.

[0028] Several collision blocks 153 are fixedly connected to the outer surface of the connecting rod 152. A moving block 171 is provided on the left side of the connecting rod 152. An electric push rod 17 is fixedly connected to the left side of the inner wall of the outer shell 1. The right output end of the electric push rod 17 is fixedly connected to the left side of the moving block 171. A collision rod 172 is slidably connected inside the moving block 171. A spring 173 is sleeved on the outside of the collision rod 172. After the crushing work is completed, the electric push rod 17 is started to drive the moving block 171 to move to the right, so that the collision rod 172 moves to the position of the collision block 153. At this time, when the connecting rod 152 is rotating, the collision block 153 will rotate with it and come into contact with the collision rod 172. This process is repeated so that the connecting rod 152 and the grinding roller 151 can vibrate, clean the attached powder, reduce the residue, and facilitate the next crushing work.

[0029] The collision rod 172 is hemispherical on the right side, and the collision block 153 is arc-shaped. The collision rod 172 passes through the moving block 171 on the right side and extends to the outside. The spring 173 is fixedly connected to the outside of the collision rod 172 on the left side and to the inner wall of the moving block 171 on the right side.

[0030] A circular hole is provided at the bottom of the rotating rod 141, and a stabilizing rod 155 is fixedly connected to the top of the grinding roller 151. The stabilizing rod 155 is set in the circular hole at the bottom of the rotating rod 141 and is rotatably connected to the rotating rod 141. The stabilizing rod 155 and the rotating rod 141 are axially fixedly connected.

[0031] A specific application of this embodiment is as follows: In use, the second motor 121 is started to drive the second pulley 144 on the right side to rotate, and through belt transmission, it drives the second pulley 144 on the left side to rotate. At this time, the rotating rod 141 drives the crushing blade 142 to rotate together, and the first motor 161 is started. The first pulley 154 on the left side rotates, and the first pulley 154 on the right side rotates via belt drive. At this time, the connecting rod 152 and the grinding roller 151 rotate together. The stabilizing rod 155 at the top of the grinding roller 151 rotates inside the circular hole at the bottom of the rotating rod 141, improving the stability of the grinding roller 151. Then, the worker puts the material into the feed hopper 11, so that the material enters the crushing box 13. At this time, the crushing blade 142 and the fixing rod 143 cooperate to crush the material. Then the crushed material leaks out from the conical ring 132 and is guided to the side of the grinding roller 151. Then the grinding roller 151 grinds the material into powder by cooperating with the bottom of the crushing box 13. This method can improve the crushing effect and greatly reduce the occurrence of particle mixing. Then it is discharged from the bottom of the crushing box 13 and enters the screen plate 2. After being filtered by the screen plate 2, the powder enters the collection box 3 for collection. The remaining particles are discharged from the right side of the screen plate 2. The protrusion 21 is used to block the material, so that the material is filtered better and the powder is prevented from directly passing through the screen. The powder is discharged from the right side of plate 2, and the inclined plate 22 at the bottom of the sieve plate 2 acts as a guide, allowing the powder to smoothly enter the collection box 3 for collection. After the crushing work is completed, the electric push rod 17 is started to drive the moving block 171 to the right, so that the collision rod 172 moves to the position of the collision block 153. Then the electric push rod 17 stops. At this time, the connecting rod 152 rotates, which causes the collision block 153 to rotate with it and collide with the collision rod 172, thereby pushing the collision rod 172 into the moving block 171 and stretching the spring 173. At this time, the outer side of the collision block 153 smoothly passes the collision rod 172. After the collision rod 172 disengages from the collision block 153, it resets under the action of elasticity. This process is repeated so that the connecting rod 152 and the grinding roller 151 can vibrate, cleaning the powder attached to the grinding roller 151, reducing the residue, and facilitating the next crushing work. After cleaning, the electric push rod 17 is started to drive the moving block 171 to reset to the left, so that the collision rod 172 is away from the collision block 153.
