A non-contact swing granulation device for materials and bearings

Abstract

The invention relates to the technical field of pharmaceutical equipment, in particular to a material and bearing non-contact type swing pelletizing device. The device comprises a material hopper used for containing materials, an extruding assembly and a driving part, wherein the material hopper is provided with a material inlet and a material outlet, and a screen plate is arranged on the material outlet; the extruding assembly is matched with the screen plate; the driving part is arranged outside the material hopper and used for driving the extruding assembly, the extruding assembly stretches out of the material hopper and is matched with the driving part, and the portion, for the extruding assembly to stretch out, of the material hopper is spaced from the material containing position in the material hopper. Due to the scheme, on one hand, the black spot phenomenon is avoided, the medicine effect of medicine is guaranteed, and medicine safety is guaranteed; on the other hand, it can also be avoided that materials enter a transmission part, and accordingly the risk that lubricating performance is weakened, and running reliability and safety of the pelletizing device are guaranteed while work efficiency of the pelletizing device is improved.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical equipment, in particular to a non-contact swing granulation device for materials and bearings. Background technique [0002] In the field of pharmaceutical equipment technology, granulation equipment usually includes a hopper for holding materials. A roller is arranged in the hopper, and a screen is arranged under the roller. In actual use, the materials are placed in the hopper, and the roller The material is buried in it. At this time, start the granulation equipment, and the rollers run alternately in forward and reverse directions to squeeze the material in the hopper to the lower screen, and the material is extruded from the screen hole to realize granulation or whole process. grain purpose. Particles with different particle size requirements can be obtained by replacing the screens with different apertures. [0003] Although the granulator with the above-mentioned structure can grin...

AI Technical Summary

Problems solved by technology

[0003] Although the granulator with the above-mentioned structure can grind or extrude the material well, and can also obtain the required particles with different particle sizes, after further research and development, the inventor of the present application found that the granulator with the above-mentioned structure There are unavoidable defects in the device, which are also defects that affect the quality of the industry, as follows:

[0004] Since the rollers are set in the hopper, one end of the transmission device that drives the rollers is connected to the rollers, and the other end passes through the hopper to connect with the external driving parts. Where the transmission device passes through the hopper, it is usually supported and sealed by a bearing device. , to avoid material spilling outside the hopper, however, in actual working conditions, the material in the hopper will completely bury the bearing sealing device while burying the roller, and the current bearing device itself has a certain gap, so, in practice During the working process, some materials will enter the interior of the bearing device along these gaps. These materials entering the interior of the bearing device will either be polluted by the lubricant inside the bearing device, or stay in the bearing device for a long time and become expired or moldy, or Due to the frictional heating of the bearing device and the deterioration, these deteriorated materials will enter the hopper from time to time during the entire production process, and new materials will enter the bearing device at the same time, so, first of all, it causes waste; and, more importantly The most important thing is that after these deteriorated materials enter the material, they continue to enter the follow-up process and finally appear in the finished drug. This is the "black spot" phenomenon that is difficult to eliminate in this industry. If it is not effective, it is very likely to contaminate the agent and cause serious medical accidents; on the other hand, the lubricant of the bearing device also has the risk of leaking into the hopper to contaminate the material, resulting in the occurrence of "black spots"; on the other hand, the material entering the In the bearing device, the lubricating effect of the lubricant is reduced, which increases the internal friction of the bearing device and the internal friction of the bearing device. While reducing the working efficiency of the granulation equipment, it also reduces the reliability of the granulation equipment. Make the granulation equipment have a greater risk of failure
