Embodiment approach
[0034]As the first embodiment of the electromagnetic heater in the corrugated cardboard heating device of the present invention, each electromagnetic heater includes a metal body and an electromagnetic induction coil surrounding the metal body, and the electromagnetic induction coil is wound with a magnetically conductive copper wire. And the electromagnetic induction coil is provided with a cooling device, the cooling device is a Teflon water pipe arranged close to the electromagnetic heater, and the electromagnetic heater is cooled by the cooling device to ensure the service life of the electromagnetic heater. Also, because the surface temperature of each roller body and each preheating cylinder reaches above 150°C during use, a heat-conducting silica gel is arranged at the bottom of the electromagnetic induction coil, and a guide hole is pierced on the heat-conducting silica gel, and a Teflon is pierced on the guide hole. Water pipe, there is circulating water in the Teflon ...

The invention relates to the technical field of corrugating machines, and particularly relates to a corrugated board pitting machine heating device and a corrugating machine. The corrugated board pitting machine heating device is arranged in the corrugating machine. The corrugating machine comprises a surface paper preheating cylinder, a first preheating cylinder, a pressure roller, a pitting paper preheating cylinder, an upper pitting roller and a lower pitting roller, wherein the upper pitting roller, the lower pitting roller and the pressure roller are all hollow roller bodies; each rollerbody and each preheating cylinder are filled with water; the outer portion of each roller body and the outer portion of each preheating cylinder are each provided with an electromagnetic heater; the water in the roller bodies and / or the preheating cylinders is correspondingly heated through the electromagnetic heaters; the heating device further comprises a variable-frequency power source; and each electromagnetic heater and the variable-frequency power source form a conductive loop. According to the corrugated board pitting machine heating device and the corrugating machine, the effect that steam heating is replaced with electromagnetic heating is achieved, the preheating time is shortened, steam pipelines and parts matched with steam heating can be correspondingly detached, the production cost is reduced, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of corrugating machines, in particular to a corrugated cardboard pit machine heating device and a corrugating machine. Background technique [0002] With the development of the economy, the scale and technical level of the carton packaging industry have increased rapidly. Generally, corrugated cardboard is used for packaging. Corrugated cardboard is not only light and beautiful, suitable for large-scale production, but also capable of recycling and reuse. [0003] The corrugating roller is the core component of the cardboard production line. Through the engagement of the upper and lower corrugating rollers, the corrugating base paper is processed into a wave-shaped corrugated shape. In the existing production process of corrugated cardboard, in order to form and bond the corrugated paper, the base paper must be dried, and the temperature of the pit roll, pressure roll, and preheating cylinder must reach abou...
