Abstract

The invention provides an electromagnetic heating roll temperature control method and a system thereof. The method comprises the following steps: S100, at least three temperature measuring units distributed around the roll body detect temperature data of a roll body surface corresponding to each temperature measuring unit; S200, whether the temperature data obtained by each temperature measuring unit are within a tolerant deviation range of the average temperature data value T obtained by all temperature measuring units is judged, and if yes, a step S400 is executed, and if not, a step S300 isexecuted; S300, a temperature measuring unit exceeding the tolerant deviation range is closed, and the step S100 is returned; S400, the temperature data obtained by all temperature measuring units are compared, and the lowest temperature data are used as the whole temperature data of the current roll body surface; and S500, according to comparison between the whole temperature data of the currentroll body surface and a preset process temperature, the heating unit of the roll body is adjusted. The temperature stability during a large roll body low-speed production process can be realized, andthe production efficiency and the product qualification rate are improved.

Description

technical field [0001] The invention relates to the technical field of electromagnetic heating rollers, in particular to a method and system for controlling the temperature of electromagnetic heating rollers. Background technique [0002] Electromagnetic heating rollers are widely used in the processing and production of various polymer materials. Its good temperature characteristics are recognized by manufacturers in various industries. And some industries must have it. [0003] The electromagnetic heating roller is divided into two parts: the inner shaft and the roller shell. Usually one or more sets of coils are arranged on the inner shaft for generating electromagnetic fields. Wherein, the direction of the coil wire can be set vertically or horizontally. For the temperature measurement of the existing electromagnetic heating roller, one or two small holes of different depths are transversely opened in the roller wall of the roller body. A temperature sampling probe ...
