Small-sized wet spinning device

Abstract

The invention relates to a small-sized wet spinning device. The device comprises a spinning solution conveying machine, and a spinneret orifice, a coagulating bath and a winding roller which are connected with an outlet of the spinning solution conveying machine, wherein the spinning solution conveying machine consists of a spinneret hydraulic cylinder, a piston, a screw and a screw motor; a spinneret is fixed at the lower end of the spinneret hydraulic cylinder; the spinneret orifice is formed in the spinneret and communicated with an inner space of the spinneret hydraulic cylinder; a check valve is arranged at the upper end of the spinneret orifice on the spinneret; and the coagulating bath consists of a coagulating bath groove. In the small-sized wet spinning device, the conveying machine consists of the spinneret hydraulic cylinder, the screw, the piston and the screw motor, and the check valve is arranged between the spinneret hydraulic cylinder and the spinneret orifice, so spinning solution can be sprayed from the spinneret orifice when the pressure of the spinning solution is increased to a certain value; the screw motor, a motor of a drawing roller and a motor of the winding roller are connected with a controller; the rotating speed and rotating direction of each motor can be controlled respectively; and silks with certain drawing ratio and fineness can be obtained according to the experimental requirement.

Description

Technical field: [0001] The invention relates to a textile machine, in particular to a spinning device, in particular to a small wet spinning device, which can be used in a laboratory for a small amount of fiber spinning experiments. Background technique: [0002] The existing wet spinning device is mainly used in the mass production of synthetic fiber spinning, which is a large spinning device with complicated equipment and high cost. However, the spinning performance and spinning process of some regenerated protein fibers are still in the experimental research stage, and it is not convenient to use large-scale production equipment in the laboratory for frequent experiments. At the same time, the existing production equipment cannot be used to study the fiber spinning process parameters. Invention content: [0003] The purpose of the present invention is to provide a small-scale wet spinning device, which will solve the problem that the production-type spinning device in ...
