Rolling device for heat conduction pipe type thermal-sensitive ceramic heating element

Abstract

The invention discloses a rolling device for a heat conduction pipe type thermal-sensitive ceramic heating element. The rolling device comprises at least three groups of rolling wheels; the pressing planes of each group of rolling wheels are in contact with the heat conduction plane of the heat conduction pipe; each group of rolling wheels are arranged in an up-down symmetrical manner, and are provided with an adjusting or controlling apparatus used for adjusting pressure and displacement of the center distance of the group of rolling wheels; the adjusting or controlling apparatus comprises but not limited to a spring, an air pressure part or a hydraulic part; the pressure / displacement of the rolling wheels are adjusted by setting a dial gauge capable of observing the relative distance between the rolling surfaces of each group of rolling wheels, and a pressure gage for displaying fine tuning pressure, so that the purpose of uniformly applying force on the heating surface of the heating element is achieved. The invention also provides a positioning tool without causing displacements of an electrified lead-out terminal, an insulating layer and a ceramic sheet in the heat conduction pipe, a guide width-limiting apparatus and a material-discharge leveling apparatus. According to the rolling device, the electrical safety of the product is improved, the consistency, reliability and production efficiency are greatly improved, and the manufacturing cost of the product is greatly lowered.

Description

technical field [0001] The invention relates to a rolling equipment, in particular to a rolling equipment for a heat-conducting tube type heat-sensitive ceramic heating element. Background technique [0002] Existing heat-sensitive ceramic heating elements are generally composed of a heat-sensitive ceramic heating sheet clamped between two electrode sheets, and a heating core covered with an insulating film on the surface of the electrode sheet penetrates into a heat-conducting tube. Since there is a large gap between the heating core covered by the insulating film and the inner wall of the heat conducting tube and between the parts inside the heating core after penetrating the heat conducting tube, it is necessary to pressurize the heat conducting tube to achieve the heating core and heat conduction. The heat conduction and heat conduction effect of the tight combination between the tubes and the parts inside the heating core. Existing pressing equipment generally adopts t...
