Cocoon screening device

Abstract

The invention discloses a cocoon screening device comprising a conveyor belt. A push plate and a link plate are arranged in the middle of the conveyor belt and form uniform barriers, a plurality of sheet iron are uniformly distributed on one side of the conveyor belt, a feeding plate, a perspective plate, a plurality of door plates and a cocoon pool are arranged below the conveyor belt in sequence, the upper planes of the feeding plate, the perspective plate and the door plates are positioned on a same plane, a CCD (Charge Coupled Device) camera is arranged above the perspective plate, a fluorescent lamp source is arranged below the perspective plate, the plurality of door plates form a door plate array and correspond to the barriers between each two sheet iron one to one, a gas cylinder is arranged below each door plate and is controlled by virtue of each solenoid valve, and an inferior-quality product pool is arranged below the gas cylinders. The cocoon screening device is used for automatically screening cocoons on line without damaging the cocoons, is simple to operate, and not only reduces the labor intensity of workers to a great degree, but also ensures the cocoon screening result to be more accurate and objective.

Description

Technical field [0001] The invention belongs to the technical field of silkworm cocoon processing, and particularly relates to a silkworm cocoon screening device. Background technique [0002] When reeling silkworm cocoons, the quality of silkworm cocoons has a great influence on the quality of silk reeling. As the raw material cocoons used in silk reeling factories generally have poor cocoon quality, uneven cocoon particle size, mixed cocoons, and low cocoon uniformity, which affect the quality of raw silk, it is necessary to screen cocoons according to the requirements of process design , Eliminate the unreelable lower foot cocoons in the raw cocoons; the current screening process of silkworm cocoons generally adopts manual screening, and the workers select the cocoons that are too large, too small, and double pupae under fluorescent lights according to the observed perspective of the cocoons. . This method has high labor intensity, easy to cause visual fatigue, and great dam...

Problems solved by technology

As the raw material cocoons used in silk reeling factories generally have poor cocoon quality, uneven cocoon particle size, mixed batches of cocoons, low uniformity of cocoon shape, etc., which affect the quality of raw silk, it is necessary to screen silkworm cocoons according to the requirements of process design. , remove the leftover cocoons that cannot be reeled from the raw material cocoons; at present, the silkworm cocoon screening process generally adopts manual screening, and the workers select the cocoons that are too large, the cocoons that are too small, and the cocoons with double chrysalis under the fluorescent lamp according to the perspective of the cocoons observed.

This method is labor-intensive for workers, which is likely to cause visual fatigue and cause great damage to the eyes of workers. At the same time, manual cocoon selection is highly competent, low in efficiency, and the phenomenon of cocoon mixing is serious.
