Electrical heating setting roller

Abstract

The invention discloses an electric heating hot-setting roller, wherein, an outer sleeve of the roller is sleeved outside an inner sleeve; the central section of a front plate is provided with a positioning surface; front ends and rear ends of the outer sleeve and the inner sleeve are fixedly connected with the front plate and a rear plate to form a main cavity; electric heaters are arranged inside the main cavity along the circumferential direction; a hot resistance is arranged on the rear plate; and heat-conducting media are filled in the main cavity. The electric heating hot-setting roller also comprises a jacket, an inner rib plate, drop plugs, a protecting cap and a soaking plate, wherein, the jacket is arranged inside the inner sleeve and welded with the surface of the inner sleeve through the inner rib plate to form an auxiliary cavity; a plurality of auxiliary cavities are uniformly arranged on the surface of the inside of the inner sleeve along the circumferential direction; the auxiliary cavities are connected with the main cavity via through holes; the drop plugs are arranged inside the through holes; the soaking plate is fixedly connected with the surface of the inner sleeve and arranged inside the main cavity; the protecting cap is a circular plate and is fixedly connected with the rear plate; an expander is arranged on the surface of the inner sleeve and takes the shape of a hollow cylinder; and a sylphon is arranged inside the cylinder. The electric heating hot-setting roller adopts the electric heating and heating medium heat-conducting technology, is uniform in heat transmission and is safe and reliable, and can freely set the heating temperature.

Description

technical field [0001] The invention relates to a heat-setting roller, in particular to a heat-setting roller on a tension heat-setting machine used for drying and setting fibers in a post-treatment production line of chemical fiber short fibers. Background technique [0002] Tension heat setting machine is the key equipment in the chemical fiber staple fiber post-processing production line. Its function is to dry, heat, heat up and shape the fiber that has been drawn to a certain size under a certain tension, so as to improve the fiber strength. , The elongation is reduced, and the finished fiber has good dimensional stability. The heating and setting of fibers is realized by contacting heat transfer with the surface of the heat setting roller, and the surface of the roller is required to have a higher temperature. [0003] In order to realize the heat setting of fibers at high temperature, the heat setting roller on the existing tension heat setting machine generally adop...

Problems solved by technology

Although this method can avoid the use of steam boiler equipment during operation and only provide heat source through the heater, it is difficult to control the heating temperature of the heater in time. When the heating temperature of the heater is too high, if measures are not taken in time, It is easy to cause damage to the heat setting roller equipment and affect the safety of production
