Abstract

The invention discloses a preheater, which includes a frame, a preheating cylinder, and a paper guide roller. The preheating cylinder and the paper guide roller are arranged on the frame, and also includes a humidity sensor, a servo motor, a controller, and a humidity sensor. It is installed at the paper feeding end of the preheating cylinder, the servo motor is set on the frame, and the controller is electrically connected with the humidity sensor and the servo motor respectively; There is a steam inlet on the preheating chamber; a tension control mechanism for controlling the tension of the paper is provided on the paper inlet side and the paper outlet side of the preheating cylinder, and the tension control mechanism includes a lifting cylinder, a solenoid valve and a The runner on the top of the lifting cylinder, the solenoid valve is used to realize the lifting of the lifting cylinder, and the solenoid valve is electrically connected with the controller. Compared with the prior art, there is no need to set corner-wrapped rollers to adjust the bonding area of ​​the paper and the preheating cylinder, and directly adjust the bonding area of ​​the paper and the preheating cylinder by adjusting the rotation direction and angle of the preheating cylinder.

Description

technical field [0001] The invention relates to the technical field of corrugated cardboard production, in particular to a preheater. Background technique [0002] Corrugated paper is a plate made of liner paper and corrugated corrugated paper formed by corrugating rollers. It is generally divided into two types: single corrugated board and double corrugated board. In the production line of corrugated paper, it is necessary to use a preheater to preheat the raw material to provide a certain amount of heat to the raw paper and adjust its moisture to reduce the moisture content of the paper web and make it more uniform. In the south of China, due to the low indoor and outdoor temperature and low relative humidity in winter, the raw material paper from the corrugator loses moisture quickly, and the moisture content of the raw paper tends to be consistent with the moisture content in the surrounding air. The moisture content of the base paper is in the range of 10-14%, and the ...
