False-twist rotor with constant-temperature heating device

Abstract

The invention provides a false-twist rotor with a constant-temperature heating device. The false-twist rotor is characterized in that a first circular ring copper electrode and a second circular ring copper electrode are respectively installed on the outer circle of a ceramic circular ring in a sleeved mode, and the ceramic circular ring provided with a longitudinal hole and a spiral hole is arranged on a cylindrical ceramic column in a sleeved mode; two leads of an electric heating coil in a groove formed in the inner circle surface of the ceramic circular ring are jointly connected and fixed to the first circular ring copper electrode and the second circular ring copper electrode respectively; two electric brushes jointly contact the first circular ring copper electrode and the second circular ring copper electrode respectively; wires on the electric brushes are connected with a direct current power cord, wherein an electric control switch is arranged between the wires and the power cord. The electric brushes are used for power supplying and heating of the electric heating coil and then heat transmission to the cylindrical ceramic column, as a result, the cylindrical ceramic column can keep a certain constant temperature, and a bearing installed on the lower portion of the cylindrical ceramic column in a sleeved mode can be installed on a mounting base; under the circumstance that the width of a twisting triangular area is kept unchanged, the length of the twisting triangular area is reduced, gather fibers for twisting are enhanced, as a result, fiber migration of yarn is changed, and the strength and abrasive resistance of the yarn are improved.

Description

technical field [0001] The invention relates to a textile constant temperature heating false twisting device, in particular to a false twisting rotor with a constant temperature heating function, which is used on spinning frames to improve yarn quality. Background technique [0002] In the ordinary ring spinning process, the roving reaches the nip of the front roller after drafting and becomes a strand of a certain width. The strands are twisted to form a triangular area, which is usually called a twisting triangle. The fibers at the edge of the twisting triangle often form flying flowers or hairiness, and only a small part is twisted into the yarn body. The existence of the twisting triangle is the main reason for yarn hairiness, but the twisting triangle is also an important place for fiber transfer in the yarn body. Blindly eliminating the twisting triangular area to reduce yarn hairiness, such as compact spinning, has an adverse effect on the yarn structure, making the ...
