Description

A texturing machine

Technical Field

The utility model relates to the field of textile equipment, in particular to a texturing machine.

Background technique

A texturing machine is a textile machine that can process untwisted yarns such as polyester and polypropylene into elastic yarns with medium elasticity and low elasticity through false twisting. A texturing machine generally consists of a raw yarn rack, a wire cutter, a first roller, a deformation heat box (upper heat box), a twister, a third roller, a qualitative heat box (lower heat box), a third roller, a wire probe, an upper oil wheel, and a DTY winding device. Among them, the raw yarn rack occupies the largest area and is the carrier of the silk material. It is particularly important in the texturing machine. However, the raw yarn rack in the existing texturing machine fixes and supports the silk reel by extrusion, and the silk reel will be unstable when it rotates. In addition, the connection between the traditional raw yarn rack and the silk reel includes an inclined upward joystick, so that the connection and disassembly steps of the silk reel need to be performed from bottom to top in sequence, and the operation is limited and inconvenient. For this reason, we propose a texturing machine.
