Automatic control device of powder height

Abstract

An automatic control device of a powder height comprises a feeding mechanism and a material powder height detection machine. The material powder height detection machine comprises a square charging barrel, a supporting plate, a support, a quantitative discharging supporting plate, a quantitative discharging pulling plate and a material powder height detector. The charging barrel is fixed on the supporting plate. The quantitative discharging pulling plate is arranged in a pulling plate chute on an upper end surface of the support. The supporting plate is fixed on the upper end surface of the support. During a blanking state, a discharging hole on the supporting plate forms butt joint with a discharging hole on the quantitative discharging pulling plate. The quantitative discharging pulling plate is driven by a cam driving mechanism. The material powder height detection machine is formed by four capacitance pole plates. The two capacitance pole plates are sticked on inner walls of left and right sidewalls of the charging barrel respectively, the other two capacitance pole plates are arranged in a central section of the charging barrel and two ends are fixedly connected with a front wall and a rear wall of the charging barrel respectively. By using the device of the invention, the powder height can be effectively detected; real-time control of the powder height is realized and finished drug quality is increased.

Description

technical field [0001] The invention belongs to an automatic control device for the height of powdered materials of a charging machine, which can realize the detection of the height of powdered materials and the addition of powdered materials. Background technique [0002] There is no powder height detection and powder adding device in the traditional charging machine. As the powder height in the hopper decreases, the pressure of the powder at the bottom of the hopper changes. When there is more powder in the hopper, The pressure on the bottom material powder is large; on the contrary, the pressure on the bottom material powder is small, which results in the unequal quality of the material powder under the premise of the same volume, resulting in errors in the production process and product quality. decline, so it is necessary to improve this phenomenon. Contents of the invention [0003] The object of the present invention is to provide an automatic control device for th...
