Description

113501

The invention relates to the production of raw silk and can be used in the preparation of cocoons for unwinding.

The purpose of the invention is to increase the efficiency of searching for the ends of the threads.

The drawing shows schematically a device for searching for koi.

tsov threads.

The device contains a cauldron kettle 1 and a disc holder 2c with coaxially mounted with the possibility of reciprocating movement. It is equipped with a thread-holding means 3 made of porous material in the form of a glass with a central opening E at the end. The disk holder has an end central protrusion A, placed in the hole of the glass and forming an annular channel for the cocoons with its walls. The walls of the cup can be made of a thickness corresponding to two cocoon diameters, the porous material has a modulus of elasticity of 50-100 kg / mm and a pore size of 0.5-1.5 mm2 which provides the best conditions: for looking for threads.

A material with a large modulus of elasticity damages the cocoons; with a smaller modulus of elasticity, the process of finding the ends of the filaments is not sufficiently effective. The porosity of the material of the stranded C1 approximately corresponds to the surface of the cocoon shell.

The holder 2 is mounted on a reciprocating shaft 5.

The device works as follows.

 Cocoons fall asleep in a cauldron pot 1 and. Cover them with a disk holder 2 with a glass 3 with immersion of cocoons in water. The cocoons that are in the water under the glass 3 are treated with steam supplied from the pipe. In the working position, the walls of the glass 3 are immersed in water by the size of the cocoon and all the cocoons turned out to be in the annular channel. This ensures the isolation of cocoons from the environment and creates the same conditions for the evaporation of the entire mass of cocoons in the pot. Impregnation with water is carried out uniformly with the same degree of steaming.

1-2 minutes after the disc holder 2 is lowered into the steam kettle and the steam supply, the shaft drive 5 is turned on and the disk holder and the glass 3 are given a reciprocating rotational movement around the vertical axis,

The cocoons in the annular channel move in concentric arcs and due to. the water resistance lags in phase from the movement of the surface of the glass, which rotates the cocoons relative to their longitudinal axis, located radially relative to the end. The protrusion 4 in the center of the disk displaces the cocoons from the dead space, thanks to t.fy, all the cocoons are processed simultaneously. The ends of the cocoon threads are separated from the shell and cling to the microporosity of the glass.

The effect of finding and engaging. the ends of the threads are provided by using a material with an elastic modulus of 50-100 kg / mm and a pore size of 0.5-1.5 mm, which corresponds to the asperity of the cocoon shell.

At the end of the cocoon processing cycle, the disk holder with the thread-gripping means lifts and removes the hooked ends of the cocoon filaments from glass 3. The cocoons with the ends of the filaments are transferred for further processing.

The proposed device for searching for the ends of the cocoon filaments provides a reduction in the yield of the peeling and, accordingly, an increase in the effect on finding the ends of the filaments on the cocoons.
