Medicinal material screening vibration motor

Abstract

The invention discloses a medicinal material screening vibration motor. The vibration motor is to generate a lot of heat in a working process. First, when the vibration motor does not work, a fine gapexists between a shaft and a bearing. With continuous rise of temperature, the shaft is heated to expand, and the gap therebetween becomes smaller and smaller, so that the force of friction is increased and the temperature is raised quickly. When a rated temperature is reached, relatively large damage is posed to the integral vibration motor. Second, when the temperature reaches the rated temperature, use of inner lines is affected, so that a certain electric leakage risk exists. The temperature of the surface of a rotor becomes higher and higher, so that transferred heat is conveyed to a temperature sensing module through a heat conducting wire in contact with a movable block slowly, and the temperature sensing module makes a signal response. If the temperature exceeds the rated temperature, the temperature sensor module enables a telescopic rod to extrude toward the surface of the rotor to drive a brake to brake the rotor so as to force the integral vibration motor to stop working,so that a condition that inner parts and circuits are damaged due to overtemperature is avoided.

Description

technical field [0001] The invention relates to the technical field of medicinal material screening, in particular to a vibration motor for medicinal material screening. Background technique [0002] Medicinal materials are the raw materials for pharmaceuticals, especially Chinese medicinal materials in China, that is, raw materials of traditional Chinese medicine that have not been processed or made into finished products. Traditional Chinese medicine is a traditional Chinese medicinal material. It also integrates the unique cultural phenomenon of Chinese and Western medicine created by modern Western medicine civilization. It is an important part of Chinese excellent culture. There are high-quality medicinal materials and defective products, which need to be screened by a vibrating sieve. The core of a vibrating sieve The component is a vibration motor. The vibration motor is installed with a set of adjustable eccentric blocks at both ends of the rotor shaft. The centrifug...

Problems solved by technology

[0003] The current vibrating motor will generate a lot of heat during the working process. First, there is a small gap between the shaft and the bearing when it is not working. As the temperature continues to rise, the shaft is heated and expands. The gap is getting smaller and smaller, resulting in increased friction and faster temperature rise. When the rated temperature is reached, it will cause greater damage to the whole. Second, when the temperature reaches the rated temperature, it will affect the use of internal circuits, which has a certain Leakage safety risk
