Novel automatic screw feeding device

Abstract

The invention provides a novel automatic screw feeding device. The novel automatic screw feeding device comprises a hopper, and a hopper upper cover arranged above the hopper, wherein a rotatable filter plate is arranged in the upper opening of the hopper; the filter plate is provided with a plurality of circular holes; rotatable circular baffle plates are arranged inside the filter plate; the inner diameters of the circular baffle plates are greater than the inner diameters of the circular holes; the bottom of the hopper is connected with a vibrating motor and a damped rotation type level gage respectively; the lower opening of the hopper is connected with a screw charging device; the screw charging device comprises a speed reducing motor, a screw rod and a discharging guide sleeve which are connected in sequence. The novel automatic screw feeding device has the beneficial effects that operation is simple and convenient through PLC (Programmable Logic Controller) automatic control; by arranging the filter plate, the falling speed of medical powder is controlled, and large blocks of medical powder are prevented from entering the hopper; by arranging the vibrating motor, the medical powder is prevented from coagulating; by arranging the damped rotation type level gage, the medical powder amount can be detected and controlled.

Description

technical field [0001] The invention belongs to the field of industrial automation control, and in particular relates to a novel automatic screw feeding device. Background technique [0002] The screw feeding device is one of the indispensable production equipment in modern industry. Its working efficiency directly affects the overall production efficiency. It is imperative to fully optimize the screw feeding device and improve its working efficiency. [0003] In the prior art, the screw feeding device in industrial production has the following disadvantages: 1. The direct entry of large pieces of medicinal powder into the hopper will cause blockage, and the falling speed of the medicinal powder cannot be controlled. 2. Due to the high height of the hopper, the powder at the bottom of the hopper is easy to condense into lumps, causing the powder to fail to fall normally. 3. The amount of powder sent into the screw feeding device is difficult to detect and control, resulting...
