Abstract

The invention discloses a preheater which comprises a rack, a preheating cylinder, a paper guide roller and a preheating cylinder, wherein the paper guide roller is arranged on the rack and also comprises a humidity sensor, a servo motor and a controller, the humidity sensor is arranged at the paper feeding end of the preheating cylinder, the servo motor is arranged on the rack, and the controlleris electrically connected with the humidity sensor and the servo motor respectively; the preheating cylinder is cylindrical, a preheating cavity in contact with corrugated paper is arranged in the preheating cylinder, and a steam inlet is formed in the preheating cavity; the paper feeding side and the paper discharging side of the preheating cylinder are respectively provided with a tension control mechanism for controlling paper tension, each tension control mechanism comprises a lifting cylinder, an electromagnetic valve and a rotating wheel arranged at the top of the lifting cylinder, eachelectromagnetic valve is used for realizing lifting of the corresponding lifting cylinder, and each electromagnetic valve is electrically connected with the controller. Compared with the prior art, the preheater has the advantages that the circumstance that the area of the portion, which is attached to the preheating cylinder, of paper is adjusted by arrangement of a corner wrapping roller is avoided, and the area of the portion, which is attached to the preheating cylinder, of the paper is adjusted by directly adjusting the rotating 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 ...
