Cocoon inside-out turning device

Abstract

A cocoon inside-out turning device is characterized in that the surface of a turnplate is raised out to form a protruding edge, cocoon cavities are arranged evenly in the protruding edge, a guide passage is arranged in each cocoon cavity and is communicated with the same, the turnplate is provided with a discharge spot at six o'clock, a feed spot at nine o'clock and a turning spot at twelve o'clock, a perforating spot is positioned between the feed spot and the turning spot, a perforating mechanism is mounted on an extension line from the center of circle of the turnplate to the perforating spot and comprises a fixed perforating cylinder and a fixed guide block, the shaft end of the perforating cylinder is fitted with a perforating component, the guide block is internally cut to form a guide face, an upper thin-walled tube is positioned above the turning spot and is externally connected with a magnetic ring cylinder, a lower ejector rod is positioned below the turning spot, and an airnozzle is positioned above the discharge spot. The perforating mechanism performs perforating on a cocoon, the cocoon is then spread by elasticity of an elastic rack, and the cocoon is then turned inside out through the linkage of the upper thin-walled tube and the lower ejector rod. The cocoon inside-out turning device is ingenious in design, allows inside-out turning to be completed efficiently,and helps maximally prevent cocoon fibers from being damaged.

Description

technical field [0001] The invention relates to a silkworm cocoon inner layer eversion device. Background technique [0002] Silkworm cocoon refers to the cocoon of the silkworm, the sac-shaped protective layer in the pupa stage of the silkworm, containing the pupa body. The cocoon layer can be reeled, and the cocoon clothing and the reeled waste silk can be used as raw materials for silk cotton and silk spinning. Silkworm cocoons are in different shapes such as long oval, oval waist-shaped, spherical or spindle-shaped, or slightly constricted in the middle. cm, the surface is white, with irregular wrinkles and attached silk, fluffy, unfeathered silkworm cocoons, with one yellow-brown silkworm pupa and light brown, shrunken silkworm skin taken off before the pupa; Before the silkworm cocoon is processed and utilized, it needs to be turned inside and outside, and the impurities such as the silkworm skin on the inside should be removed. At present, there is no machine on the...

AI Technical Summary

Problems solved by technology

Silkworm cocoons are in different shapes such as oblong, elliptical waist-shaped, spherical or spindle-shaped, or slightly constricted in the middle. The cocoons are white, yellow, light green, flesh red and other colors, about 3-4 cm long and 1.7-2.1 cm in diameter. 1 cm, white on the surface, with irregular wrinkles, and attached silk, in the form of fluff, an unemerged cocoon, with a yellow-brown silkworm chrysalis inside and light brown, shriveled silkworm skin shed off before pupae; Before processing and utilizing silkworm cocoons, it needs to be turned inside out first, and impurities such as silkworm skin on the inside should be removed. Currently, there is no machine on the market that can effectively turn silkworm cocoons, and they are all done manually. Manual operation is inefficient and labor intensive, making it difficult Meet the actual market demand
