Raw silk impregnating device

Abstract

The invention provides a raw silk impregnating device. The raw silk impregnating device comprises a machine table, a liquid storage barrel, an open-type impregnating cylinder and a driving device, wherein the liquid storage barrel is erected on the table top of the machine table and is used for storing impregnating liquid; the open-type impregnating cylinder is used for placing raw silk; the drive device is used for driving the impregnating cylinder to move horizontally along the table top of the machine table; the liquid storage barrel is communicated with the impregnating cylinder internally through a slurry pipe provided with a reversing valve. The raw silk impregnating device is characterized in that a gland which is driven to raise and drop by a power device is also arranged above the impregnating device; a slurry return hole is formed in the gland; the liquid storage barrel is also communicated with the interior of the impregnating cylinder in a manner that a reflow pipe penetrates through the slurry return hole. When the gland of the raw silk impregnating device is pressed down, the impregnating liquid and the raw silk are extruded; when the gland raises, a pressure can also be generated to the impregnating liquid and the raw silk by a short-time negative pressure generated in the impregnating cylinder; the gland raises and drops to enable the raw silk to suck and spit the impregnating liquid repeatedly, so that an auxiliary in the impregnating liquid penetrates into reeled silk quickly, and the impregnating time is greatly shortened.

Description

technical field [0001] The invention relates to a raw silk dipping device, in particular to a raw silk dipping device with short dipping time. Background technique [0002] Raw silk is composed of silk fibroin inside the silk and sericin coated outside the silk. Sericin can protect the silk from damage and improve the strength of the silk. However, the distribution of sericin is not uniform enough and its elasticity is poor, which will also increase the number of broken ends. Therefore, it is necessary to soften the sericin by dipping to make the silk body soft and smooth, reduce the static electricity generated by friction, and improve the processing performance of raw silk. This requires a dipping device. to fulfill. At present, when impregnating raw silk, many enterprises pour the prepared impregnation solution into the water tank, shake the raw silk loose and put it into the water tank, and manually stir the raw silk with a stirring rod to complete the impregnation.
