Electric heating unit of texturing machine and heating box of texturing machine

Abstract

The invention belongs to the technical field of textile machinery, and particularly relates to an electric heating unit of a texturing machine and a heating box of the texturing machine. Against the shortcomings that an electric heating plate of an existing texturing machine is provided with a plurality of yarn ducts with fixed torque and the heat dissipation area is large, the following technicalscheme is adopted: the electric heating unit of the texturing machine includes a heat conducting main body, a yarn travelling pipe and an electric heating pipe are arranged in the heat conducting main body, the two ends of the yarn travelling pipe are exposed out of the heat conducting main body, and the electric heating unit is a single-stranded yarn single yarn channel electric heating unit ora single combination stranded yarn double yarn channel electric heating unit. The electric heating unit of the texturing machine has the advantages that a connecting portion of a fixed torque is partially or all reduced, the superficial area of the electric heating unit is reduced compared with the superficial area of an existing electric heating plate, that is, the heat dissipation area is reduced.

Description

technical field [0001] The invention belongs to the technical field of textile machinery, and in particular relates to an electric heating unit of a texturing machine and a heating box of a texturing machine. Background technique [0002] The texturing machine is the main production equipment in the chemical fiber industry. It can process untwisted yarns such as polyester and polypropylene fibers into texturized yarns with unique bulk performance and good dimensional stability through false twist deformation. A texturing machine usually includes a feeding roller, a traverse wire transfer device, a first heating box, a cooling plate, a false twister, an intermediate roller, a second heating box, a third roller, an oil tanker, a wire detector, a wire cutter, a suction Filtration devices and smoking devices, etc. Among them, the heating box plays a decisive role in the performance of the textured yarn. At the same time, since the energy consumption of the heating box accounts...

Problems solved by technology

[0004] In addition to the defect of large heat dissipation area, the electric heating plate of the existing texturing machine also has the following disadvantages: the electric heating plate body is casted by aluminum casting, and during the casting process, the wire feeding tube, The positioning between the electric heating tube and the temperature measuring tube is relatively difficult, and the relative position between the tubes cannot be guaranteed, and deviations are prone to occur, resulting in a large temperature deviation between the wire tubes in the same electric heating plate, which affects the performance of the stretched wire. What's more, when the tubes are in contact, there may be a fatal defect of scrapping; the relative position of the tubes deviates, and the distance between the tubes of the multiple electric heating plates in the texturing machine is inconsistent, even if the detected temperatures are consistent , there may still be a large gap in the actual temperature of the wire tubes of the electric heating plates; the plate body of the electric heating plate is processed by casting, and the plate body is prone to casting defects such as shrinkage cavities; It is easy to produce bending deformation, which affects the temperature balance of the heating plate body; the electric heating plate body is limited by the casting process and cost, and its length is difficult to reach the length required by the medium and high-grade wire; when one of the parts is damaged, the entire electric heating plate All boards are scrapped

[0005] The electric heating box of the existing texturing machine is equipped with multiple electric heating plates, and the spaces between the multiple electric heating plates and the outer periphery of the electric heating plates are filled with thermal insulation materials such as block rock wool.
