Screw screening device

Abstract

The invention discloses a screw screening device which comprises an outer housing, a speed reducing motor, a stirring paddle, a screening plate, a feeding port, vibrating units, a discharging port, ascreening frame and a receiving box, wherein the feeding port is located on a left side of a top end of the outer housing; the speed reducing motor is located at the center of the top end of the outerhousing; the stirring paddle is connected under the speed reducing motor; a waste discharging port is formed in a left end of the stirring paddle; a bottom end of the stirring paddle 3 is connected with a surface of the screening plate; the vibrating units are located on two sides of the bottom end of the outer housing; the discharging port is located on a lower right side of the outer housing; the discharging port is connected with a left end of the screening frame; and a right end of the screening frame is connected with the receiving box. According to the invention, the size of a requiredscreening screw head can be automatically adjusted by controlling the number of the screening plates; the vibrating units and the stirring paddle reduce a problem of blockage of the screws; a crack detecting unit, a length directing unit and a counting unit can efficiently screen out the correct number of qualified screws.

Description

【Technical field】 [0001] The invention relates to the technical field of screening, in particular to the technical field of a screw screening device. 【Background technique】 [0002] A screw is a fastener that fixes an object. Screws are usually processed by a special screw machine. Due to the large production volume and the small size of the screw, deviations in precision will inevitably occur during processing, just like batch processed screws. After the processing is completed, the screws with inconsistent sizes need to be selected. The selection process is mainly done manually. Not only is the workload heavy and time-consuming, but the selection mainly depends on visual inspection, and it is inevitable that unqualified screws will be selected as finished products. , so that the processing quality of the screw cannot be guaranteed. [0003] There are some simple screening machines that only screen the diameter of the head. The working principle is to use a pair of rollers...
