Method and device for selecting cocoon before reeling silkworm cocoon

Abstract

The invention relates to a method and a device for selecting cocoons before reeling silkworm cocoons. The method is characterized by comprising the processes of sending cocoons by wind power, stripping cocoons and selecting cocoons under lights, and the device is characterized by comprising equipment for sending the cocoons by wind power, cocoon stripping equipment and cocoon selecting equipment under the lights, wherein the process of sending the cocoons by the wind power comprises that the purchased silkworm cocoons are sucked to a conveying pipe by virtue of a suction fan and the silkworm cocoons and dust are separated by virtue of an air sealing case; the process of stripping the cocoons process comprises that waste and disordered silks outside the silkworm cocoons are stripped and the dust in the cocoon stripping process is removed; and the process of selecting cocoon under the lights comprises that the silkworm cocoons which pass are observed through the surface of a transparent box body and good cocoons and light defective cocoons are selected under the condition of reflection of the lights. The cocoon selecting device provided by the invention is easy to operate, the quality of the silkworm cocoons which enter a reeling machine is guaranteed, the labor intensity of workers is lightened, and the dust can be sucked and discharged outside before the silkworm cocoons are stripped, so that the health of the workers is protected.

Description

technical field [0001] The invention belongs to a production method and equipment in a cocoon reeling factory, and in particular relates to a cocoon selection method and device for silkworm cocoons before silk reeling. Background technique [0002] The process before silk reeling in the existing silk reeling factory is that silkworm cocoons are purchased and mixed into the warehouse, and then cocoons are selected, peeled off, cocoons are transported to the silk reeling workshop. Only by selecting the lower cocoons that cannot be reeled, such as head and macula, can the normal silk reeling be ensured. The cocoon peeling is to peel off the messy silk on the outside of the cocoon, and remove the dust in the cocoon peeling process to obtain the selected cocoons. Only the silkworm cocoons can be sent to the cocoon cooking process to cook the cocoons, and finally silk reeling is carried out. In the cocoon selection process, most of them use manual operation, which is labor-intens...

AI Technical Summary

Problems solved by technology

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 do not have vacuum devices.

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 back-end production in the workshop has caused some raw silks to produce dark colors, so the quality indicators of many high-grade silks have been affected. Therefore, reducing internal printing cocoons, making products uniform in color, and improving product quality are currently the main tasks of the silk reeling factory. one of the goals
