Wall-breaking and pulverizing machine for Chinese herbal medicines

Abstract

The invention discloses a wall-breaking and pulverizing machine for Chinese herbal medicines. The wall-breaking and pulverizing machine is characterized by comprising a machine base, a motor, a grinding barrel, grinding rods, a refrigerating device, a shock excitation part, a vibration spring, a rotary shaft and an eccentric block; the grinding barrel is positioned in a soundproof box; a cooling coil pipe is wound at the periphery of the grinding barrel, and the inner wall of the grinding barrel is smooth; an axial hollow channel is arranged on the middle part of the grinding barrel; the two ends of the hollow channel are equipped with bearings; the grinding barrel is provided with an end opening; a material collecting barrel capable of being opened and closed is arranged in the end opening; the plurality of the grinding rods are arranged in the grinding barrel; and the surface of each grinding rod is smooth. Compared with the prior art, the wall-breaking and pulverizing machine has the advantages that: the smooth grinding rods and the smooth inner surface of the grinding barrel are adopted, so that materials bear greater planar impact in a grinding process, and a stressed area is great; and meanwhile, abrasion on parts is relatively small, smaller particles can be obtained after being grinded, a material cell wall-breaking rate is higher and wall-breaking is more complete.

Description

technical field [0001] The invention relates to a crushing device, which is suitable for crushing and breaking the walls of Chinese herbal medicines. Background technique [0002] In the process of making medicines and nutritional products of Chinese herbal medicine, it is necessary to grind the raw materials to make the particle size of the product finer in order to achieve the effect of medicine. However, the existing grinding is realized by simple manual crushing technology or simple grinding equipment. , so there is low efficiency in the grinding process, the production cost is high, and the defects of poor grinding effect. [0003] The traditional traditional Chinese medicine pulverizer usually has the following structure: there is a grinding body with an O-shaped section supported on the spring, the main shaft is installed in the middle of the cylinder, the eccentric block is installed on the main shaft, the main shaft bearing is installed on the body, and through the ...

[0004] Related technical documents can refer to the Chinese utility model patent "A Superfine Pulverization Vibration Grinding Machine" (the authorized announcement number is CN203955296U) whose patent number is ZL201420351644. Shaft, the stirring shaft is equipped with propeller blades, through the joint action of the grinding medium and the propeller blades, the material is crushed, although the effect is good, but there will be a lot of friction between the grinding medium and the propeller blades during the operation, which will cause damage to the propeller blades A lot of wear, and the worn debris will inevitably enter the material, so it will pollute the material to a certain extent, and it will also reduce the service life of the propeller blade

[0005] You can refer to the Chinese utility model patent "vibrating drug ultrafine pulverizer" (authorized announcement number CN204523104U) whose patent number is ZL201520152227.8. In this patent, there are multiple protrusions inside the vibrating tank. The function of the protrusions is to make the The powder at the bottom of the tank can have better friction with the grinding rod through the raised structure to reduce the particle size of the drug. Similarly, the grinding rod and the protrusions are constantly colliding and rubbing during use. Over time, the grinding rod and the protrusion will inevitably increase. The increased wear reduces the service life; although there are additional protrusions, the overall grinding area is small, so the grinding effect is not as great as imagined
