Paperboard pressing leveler

Abstract

A paperboard pressing leveler comprises a device base used for placing paperboards, wherein a pressure levelling plate used for pressing and levelling the paperboards, a slide device used for assisting in sliding of the pressure levelling plate, a detection device used for measuring curvature and straightness of the paperboards and a control device used for controlling a motion trail of the pressure levelling plate are arranged on the device base, the detection device comprises an infrared ray emission element and an infrared ray receiving element, the infrared ray emission element and the infrared ray receiving element are kept on the same horizontal plane, the slide device comprises a sliding rod and a drive motor used for driving the sliding rod to slide downwards, the sliding rod is connected with the pressure levelling plate, and the control device comprises a control cabinet used for controlling the drive motor to work and a feedback element used for feeding signals received by the infrared ray receiving element back to the drive motor.

Description

technical field [0001] The invention relates to the field of cardboard processing equipment, in particular to a cardboard flattening machine. Background technique [0002] Cardboard is widely used in the field of packaging. People have higher and higher quality requirements for cardboard. During the production process of cardboard, due to the moisture contained in the raw materials of cardboard, the cardboard needs to be dried. During the drying process of cardboard, the moisture at the bottom of the cardboard is dried The drying speed is greater than the moisture drying speed at the top of the cardboard. When the moisture balance is restored, the cardboard will naturally warp up. The upturned cardboard will greatly affect the strength of the cardboard and the use of the cardboard. In the prior art, there are some cardboard flattening machines It appears that the cardboard is placed on the equipment platform, and then pressed down by the press plate. After the cardboard is p...

[0002] Cardboard is widely used in the field of packaging. People have higher and higher quality requirements for cardboard. During the production process of cardboard, due to the moisture contained in the raw materials of cardboard, the cardboard needs to be dried. During the drying process of cardboard, the moisture at the bottom of the cardboard is dried The drying speed is greater than the moisture drying speed at the top of the cardboard. When the moisture balance is restored, the cardboard will naturally warp up. The upturned cardboard will greatly affect the strength of the cardboard and the use of the cardboard. In the prior art, there are some cardboard flattening machines It appears that the cardboard is placed on the equipment platform, and then pressed down by the press plate. After the cardboard is pressed by the press plate for a period of time, the cardboard will be restored to flatness. However, using this method to flatten the cardboard mainly depends on the experience of the staff to judge whether the cardboard is It is flat enough, but not fine enough, and in the prior art, a press plate is usually used to give pressure to the cardboard, and the press plate can only move vertically, so that the pressure on the cardboard can only be at the center, which affects the efficiency of cardboard flattening
