Description

Automatic cocoon selection machine

Technical Field

The invention relates to the field of reeling industry, in particular to an automatic cocoon selection machine.

Background

Cocoon selection refers to a process for selecting, picking and classifying raw material cocoons according to silk making process requirements. Because the silkworm has different constitutions and environments during cocooning, and is influenced by cocoon collection, cocoon drying, transportation and the like, some inferior cocoons which are difficult to reel high-grade raw silk, cocoons which cannot be reeled, double-cocoon cocoons in which two or more silkworm chrysalis are arranged in cocoons, and the like are often found. Even if the cocoons are of the same variety, the cocoon shapes and sizes, the cocoon shells have different thicknesses, colors and the like. Therefore, cocoon selection and classification must be carried out according to different process requirements so as to meet the requirements of reeling silk.

COCOON layer mass (cooon SHELL WEIGHT) is the absolute mass of the silk layer of a COCOON, and is the most basic index for COCOON quality detection and classification. The cocoon layer amount is influenced by the components of water, protein and the like of the silkworm cocoon, the variety of the silkworm cocoon, the silkworm breeding area, the raising technique and the like. It directly or indirectly reacts the quality of silkworm cocoon in many aspects, and is a comprehensive reaction of various internal components of cocoon silk.

At present, China stipulates that a dry shell quantity method is adopted to test fresh cocoons in cocoon purchasing, but the method is complex and time-consuming, and cocoon cutting measurement is needed, and cocoons with cut edges become secondary cocoons in the silk reeling industry, so that high-quality silk cannot be reeled, and great waste is caused. The common visual hand feeling measurement method is easily influenced by personal experience of an evaluator, and the measurement precision is low.

Because the traditional silkworm cocoon quality detection technology restricts the improvement of the quality and the benefit of the silk industry in China, a method for rapidly, accurately and nondestructively detecting the cocoon layer quantity of the silkworm cocoons is urgently required to be found.

Disclosure of Invention

The invention aims to provide an automatic cocoon selection machine which can automatically distinguish the quality of silkworm cocoons and automatically screen the fresh cocoons without damaging the fresh cocoons.

In order to achieve the purpose, the technical scheme of the invention is as follows:

an automatic cocoon selection machine, comprising: the cocoon selection machine comprises a rack, cocoon selection tables, cocoon selection groove holes, cocoon selection groove baffles, near infrared light sources, beam splitters, receivers, high-pressure air nozzles, an air compressor, a collection bag and a controller, wherein 3 layers of cocoon selection tables are installed in the rack, a plurality of cocoon selection groove holes are uniformly distributed on each layer of cocoon selection table, the bottoms of the cocoon selection groove holes are provided with the cocoon selection groove baffles which are electrically opened and closed, the tail end of each layer of cocoon selection table is provided with the collection bag, the near infrared light sources are installed below the bottommost cocoon selection table at the bottom of the rack, the beam splitters are installed at the bottom of the rack corresponding to the cocoon selection groove holes, the receivers are installed at the tops of the rack corresponding to the positions of the cocoon selection groove holes, the high-pressure air nozzles are installed on one side of each layer of cocoon selection table and connected with the air compressor, the controller is installed on the side face of the rack, the input end of the controller is electrically connected with the receivers, and the output ends of the controllers are electrically connected with the high-pressure air nozzles, the cocoon selection groove baffles.

Further, the cocoon selection groove baffle is made of optical glass, so that near infrared light can penetrate through the cocoon selection groove baffle to detect the quality of fresh cocoons in the cocoon selection groove.

The working principle is as follows:

the working personnel starts the automatic cocoon selection machine, simultaneously pours fresh cocoons into the cocoon selection platform on the uppermost layer, a fresh cocoon is placed in each cocoon selection slot hole, at the moment, the near-infrared light source is started to emit near-infrared light to the fresh cocoons in each cocoon selection slot hole through the beam splitter, the near-infrared light is received by the receiver after passing through the fresh cocoons, the spectral data are sent to the controller for analysis and judgment after being subjected to digital-to-analog conversion, the controller selects whether to open a cocoon selection slot baffle plate of the related fresh cocoons according to the selection requirements preset by the working personnel so that the fresh cocoons fall to the next cocoon selection platform, after the fall is completed, the air compressor is started to blow the fresh cocoons which do not fall into a collecting bag at the tail end of the cocoon selection platform through the high-pressure air nozzle, and the next cocoon selection platform repeats the operation until the cocoon selection of the last cocoon selection platform is completed, and the cocoon selection platform on the uppermost layer is restarted.

The invention has the advantages that:

(1) the application adopts the near infrared spectrum analysis technology to detect the cocoon layer amount of the silkworm cocoons, and utilizes the near infrared spectrum cocoon selection machine to realize the purposes of rapid detection and accurate cocoon selection.

(2) The purpose that one light source covers the whole cocoon selection table is achieved by utilizing a plurality of beam splitters, cost is saved, and cocoon selection efficiency is improved.

(3) According to the automatic cocoon selection machine, a full-automatic multi-stage screening mode is adopted to automatically screen fresh cocoons, the traditional manual cocoon selection mode is overturned, and the scaling diseases existing in manual cocoon selection are thoroughly eliminated.
