Electromagnetic heating roller used for corrugating machine, application of electromagnetic heating roller and corrugating machine electromagnetic heating method

Abstract

The invention discloses an electromagnetic heating roller used for a corrugating machine, an application of the electromagnetic heating roller and a corrugating machine electromagnetic heating method, and belongs to the technical field of electromagnetic heating. The electromagnetic heating roller comprises a roller body and an electromagnetic heater. The electromagnetic heater is used for heating the roller body. The roller body is provided with a cavity for encapsulating heat-conducting liquid. The electromagnetic heater can heat the heat-conducting liquid through the roller body, so that steam is produced in the cavity of the roller body. The electromagnetic heater comprises a plurality of U-shaped magnets and an electromagnetic wire. The multiple U-shaped magnets are arranged on a straight line side by side in the axis direction of the roller body. The electromagnetic wire is wound at the two ends of the U-shaped magnets in a single-loop wire winding mode to form a coil. Corrugated paper can be uniformly heated through the electromagnetic heating roller, moisture balance of the corrugated paper in the whole width direction is ensured, and the product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic heating, and relates to an electromagnetic heating roller applied to a corrugating machine, more specifically, to an electromagnetic heating roller for a corrugating machine, its application and an electromagnetic heating method for a corrugating machine. Background technique [0002] The packaging machinery industry is one of the important pillar industries of my country's national economy. Corrugated cardboard is produced by packaging machinery. It is a common material for paper packaging boxes. It is a plate made of liner paper and corrugated corrugated paper formed by corrugating roller processing. It is more dense than wooden boxes. It is light, hard, and easy to cut in size. It can protect other packaged products from damage. It is light and beautiful, suitable for large-scale production, especially easy to recycle and reuse, and is widely used. [0003] The corrugating machine is m...

Problems solved by technology

[0009] Aiming at the problem that the existing corrugating machine heats the base paper unevenly in the production of corrugated paper, which leads to the uneven moisture content of the base paper in the entire width direction and causes the base paper to be unable to be formed or the corrugated cardboard after forming cannot meet the requirements, the invention provides a corrugating machine. Electromagnetic heating roller and its application and corrugating machine electromagnetic heating method, the use of the electromagnetic heating roller can uniformly heat the corrugated paper to ensure the moisture balance of the corrugated paper in the entire width direction
