Cambered surface friction cocoon silk gathering device and cocoon silk gathering method

Abstract

The invention provides a cambered surface friction cocoon silk gathering device and a cocoon silk gathering method. Cocoon silk of a plurality of silkworm cocoons pass through a silk passing pipe, the cocoon silk gathering device and a silk end collecting device from bottom to top; the cocoon silk penetrates out of the upper end of the silk passing pipe in a manner of deviating from the center line of the silk passing pipe and are located above a gathering guide part through the gathering guide part doing circular motion; the cocoon silk is in contact with a gathering friction part through the cooperation of the gathering guide part and a silk guide part above the gathering friction part; and in the upward lifting process of the cocoon silk, the cocoon silk is also transversely driven to move to rub with the friction surface of the friction part so as to realize automatic croisure twisting, and is gathered into raw silk through the adhesion effect of sericin on the surface of the cocoon silk. According to the invention, mechanical automatic croisure twisting can be realized. The cocoon silk gathering device is simple in structure and can be directly installed and upgraded on an original silk reeling machine, and mechanical automatic croisure twisting is achieved.

Description

technical field [0001] The invention relates to a cocoon silk gathering device of an automatic silk reeling machine, in particular to an arc surface friction cocoon silk gathering device and a cocoon silk gathering method. Background technique [0002] Silk reeling is an essential process in the silk making process. In silk reeling, replacing the artificial twist sheath is a technical problem that people have always wanted to solve but have not yet found an effective solution. The silk sheath is made of two pieces of raw silk twisted together. With the increase of the length of the silk sheath, the number of twists increases, and the extrusion and friction of the silk strips in the silk sheath are strengthened, which increases the cohesion and reduces the number of hairs on some hairs. , improve clarity. However, the artificial twisting sheath is very susceptible to the influence of human factors and causes a series of problems. Different silk reelers or different times o...

Problems solved by technology

However, the artificial twisting sheath is very susceptible to the influence of human factors and causes a series of problems

Different silk reelers or different times of twisting sheaths will also be different. Different lengths of silk sheaths and different strengths of twisting sheaths will result in different twists per unit length of silk strands, the degree of extrusion between raw silks and the degree of extrusion friction. At different times, there is a certain difference in the cohesion properties of the cocoon silk in the raw silk, which affects the quality of the raw silk

At the same time, the efficiency of manual operation is low, which seriously restricts the improvement of silk reeling labor productivity.

At present, in view of the quality and labor problems caused by the silk sheath, people have explored to realize the physical interaction between the silk strips through mechanical devices. Laboratory, cannot fully realize factory automation production
