Visual screening device for blasting beads

Abstract

The invention provides a visual screening device for blasting beads. The visual screening device comprises a material blocking bin, a discharging roller, a plurality of screening partition plates, two CCD detectors, a removing nozzle, a good product bin and a defective product bin. The discharging roller is partially located in the material blocking bin, one end of a bent screening section is arranged around the circumferential face of the discharging roller, and the discharging roller can drive the blasting beads to enter one end of the bent screening section in the rotating process, the blasting beads move to the other end along the bent screening section under driving of the discharging roller so as to fall under the action of gravity; in the falling process of the beads, the beads pass through a detection channel, the two CCD detectors on the two sides of the detection channel shoot images of the blasting beads and judge the positions of defective products, and therefore when the blasting beads continue to fall to a linear screening section, corresponding air injection holes in the removing nozzle are started, the defective blasting beads are blown to the defective product bin, and the good products vertically fall into the good product bin; and the defective products and the good products are screened through electronic identification and blowing, so that the detection efficiency and accuracy are greatly improved, and good practicability is achieved.

Description

technical field

[0001] The invention relates to the technical field of popping bead detection, in particular to a popping bead visual screening device. Background technique

[0002] At present, many tobacco mouth sticks in the tobacco industry have popping beads. The popping beads produced in the mouth stick workshop need to be inspected for quality, mainly for the size, shape, damage, color, etc. of the popping beads. After the inspection, good products and Defective products are differentiated. Existing inspections are all done manually, using light panels for visual inspection, which is not only inefficient, but also inaccurate. Each person has different inspection standards. Moreover, inspectors are prone to fatigue, requiring a large number of labors, and the cost is high. high. Contents of the invention

[0003] In view of this, it is necessary to provide a popping bead visual screening device that can not only realize the heat preservation function, save the cost ...
