Processing device and processing method for heating body

Abstract

The invention provides a processing device and a processing method for a heating body. The method comprises: when manufacturing a heating body, firstly, adding molten metal into a slurry box, until aprinting surface of a segment of a conveyor belt being immersed in the molten metal, the segment of the conveyor belt contacting with a compaction roller, coaxially fixing a cylindrical heating film carrier on a printing shaft, then starting a driving device to make a driving roll rotate, the driving roll rotating to make the printing surface which is soaked by the molten metal move to the heatingfilm carrier and abut against the heating film carrier, the molten metal in a banded printing structure being adhered to the surface of the heating film carrier, to form a heating film band. Thus, aprocess defect in the prior art of first printing and then rolling is prevented, the heating film band can be reliably attached on the heating film carrier. The processing device for a heating body ishigh in automation degree, and can improve processing efficiency.

Description

technical field [0001] The invention relates to a processing device and a processing method of a heating body. Background technique [0002] In recent years, the metal ceramic heater (MCH, metal ceramic heater) has developed rapidly. The metal ceramic heater is a heating element with PTC effect. It has the characteristics of charging, fast heating speed, small size, and high reachable temperature (up to 1000 degrees Celsius). The manufacturing process of the cermet heating element is to print metal tungsten or molybdenum-manganese paste on the ceramic flow body, heat-press and laminate, and then sinter the ceramic and metal together under the protection of a hydrogen atmosphere at 1600 °C. [0003] For the cylindrical heating element, in the prior art, the metal paste is generally printed on the flat heating film carrier first, and then the printed heating film carrier is compositely rolled into a cylindrical shape. For a cylindrical shape with a smaller diameter The heati...

Problems solved by technology

[0003] For the cylindrical heating element, in the prior art, the metal paste is generally printed on the flat heating film carrier first, and then the printed heating film carrier is compositely rolled into a cylindrical shape. For a cylindrical shape with a smaller diameter The heating body, when the heating film carrier is rolled, the strip-shaped heating film printed on the heating film carrier is subjected to a large bending stress and is easy to fall off; due to the limitation of the rolling process, the diameter of the rolled cylindrical heating body It must be larger than 8mm, and it is difficult to manufacture a heating body with a diameter smaller than 8mm
