Cocoon selection method before silkworm cocoon reeling silk

Abstract

The invention discloses a cocoon selection method before silkworm cocoon reeling silk. The method comprises the following steps of (1) a vibrating sieving step, (2) a peeling cocoons step and (3) an optically selecting step, wherein in the first step, silkworm cocoons are placed on an inclined vibrating sieve and roughly sorted according to weights; silkworm cocoons under the sieve are collected; in the second step, waste silk outside the collected silkworm cocoons are peeled; the silkworm cocoons pass through light source; and qualified silkworm cocoons are collected according to light permeability. Three steps of vibrating screening, peeling and optical selection are employed to quickly achieve cocoon selection, so short operation technology process is achieved compared with a traditional way and labor intensity is reduced; and the method is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of cocoon reeling, in particular to a cocoon selection method before silk reeling. Background technique [0002] In the process of making silk from silkworm cocoons, the collected silkworm cocoons are generally mixed together without classification, and then the cocoons are simply selected, peeled, boiled, and sent to the silk reeling workshop; In order to ensure normal silk reeling, the lower cocoons that cannot be reeled, such as macula and macula, are selected; cocoon stripping is to peel off the waste silk outside the cocoon, and remove the dust on the cocoon, and only the selected cocoon can be sent to the cocoon cooking process. Finally, silk reeling is carried out. [0003] In the cocoon selection process, most of them use manual operation, which is labor-intensive and time-consuming. The labor intensity of the workers is high, there is a lot of dust, which affects the health of the workers, and the ...

Problems solved by technology

[0003] In the cocoon selection process, most of them use manual operation, which is labor-intensive and time-consuming. The labor intensity of the workers is high, there is a lot of dust, which affects the health of the workers, and the cocoons are lost and damaged. The ability and efficiency of cocoon feeding are not ideal. It is not easy to distinguish the process of cocoon selection. Some cocoon feeding devices have complicated structures, and some have no vacuuming device.

Moreover, the current artificial cocoon selection process has a serious shortcoming. It simply selects the lower cocoons that cannot be reeled, such as double palaces, piercing heads, and yellow spots, and the inner printing cocoons that seriously affect the silk color cannot be selected, and they are sent to boiled cocoons. The workshop carries out subsequent production, which causes some raw silk to have a dark color, so the quality indicators of many high-grade silk are affected
