Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, and in particular to a multi-stage grinding and pulverizing device. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to drugs that are collected, processed, and prepared according to the principles of traditional Chinese medicine, with explained mechanisms of action, and used to guide clinical application. TCM primarily originates from natural medicines and their processed products, including plant-based, animal-based, and mineral-based drugs, as well as some chemical and biological products. Because TCM is predominantly plant-based, there is a saying that "all medicines are based on herbs." Furthermore, the efficacy and naturalness of TCM have gained recognition both domestically and internationally. Before use, TCM materials require multi-stage grinding and pulverization processes.

[0003] Existing Chinese herbal medicine pulverizing and grinding equipment generally suffers from poor material discharge after completing the material grinding and pulverizing process. Due to the lack of an efficient discharge mechanism design, the pulverized medicine powder is prone to residual accumulation in the grinder, which not only causes unnecessary loss of effective ingredients, but also seriously restricts the efficiency of continuous production. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-stage grinding and pulverizing device to solve the process defects of existing grinding and pulverizing devices mentioned in the background art, such as poor material discharge. Due to the lack of efficient material discharge mechanism design, the pulverized powder is prone to residual accumulation in the grinding chamber, which not only causes unnecessary loss of effective ingredients, but also seriously restricts the operation efficiency of continuous production.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage grinding and pulverizing device, including a base frame and a pulverizer body, wherein a lifting structure is provided on the base frame, an adjustment structure is provided on the lifting structure, and the pulverizer body is disposed on the adjustment structure;

[0012] Preferably, the clamping frame is provided with a protective layer, and the transmission chain is adapted to the sprocket.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This multi-stage grinding and pulverizing device, through its adjustable structure, optimizes both the fixing and angle adjustment systems of the pulverizer via a dual-motor drive mechanism. The clamping mechanism uses a double-headed threaded rod to drive the symmetrical clamping frame to move synchronously, ensuring that the pulverizer body receives a balanced fixing force on the rotating frame, significantly improving clamping stability. The angle adjustment mechanism drives the rotating frame to rotate smoothly through a sprocket transmission system, achieving adjustable discharge port angle and allowing the material to achieve the optimal discharge speed under gravity. The fixing and adjustment functions do not interfere with each other, ensuring both operational safety and significantly improving production efficiency.

[0015] 2. This multi-stage grinding and pulverizing device, through its lifting structure, uses a precise fit between a rotating pulley and a transmission belt to drive a rotating frame, which in turn drives a rotating threaded rod to achieve linear displacement, ultimately controlling the vertical movement of the moving plate. The guiding structure of the moving rod ensures the stability and straightness of the lifting process, making height adjustment more precise and reliable. This design significantly improves the convenience of feeding the pulverizer, allowing operators to quickly adjust the equipment to the optimal working height according to the material characteristics, effectively reducing labor intensity and improving work efficiency. The transmission belt system operates smoothly, and the threaded transmission mechanism ensures the accuracy and retention of height positioning, fully meeting the adjustment needs of different feeding conditions. The entire mechanism is responsive and accurate in positioning, achieving convenient height adjustment while maintaining structural rigidity, enabling the pulverizer to adapt to diverse production requirements and greatly improving the equipment's flexibility and operational safety.
