Abstract

The invention provides a hardboard double sided shaping dryer composed of an up and down drying device and a transmission connecting frame. The up and down drying device is composed of a beam, a beam landing leg, a canvas roller, a flat-plate drying box, a press roll device and a press roll lift mechanism device, is clamped in the hardboard between a canvas belt and the drying box and slides with the canvas belt on the smooth surface of the drying box for drying operation. Under the rolling action of a press roll as well as the ironing and drying action of the smooth surface, moisture discharge is speeded up and drying is even; and simultaneously, the hardboard is flattened, with the tightness, stiffness, tensile strength and smoothness thereof being improved. The shaping dryer is good in drying quality and high in efficiency.

Description

Double-side shaping drying device of hardboard

Technical field

What the present invention relates to is packing board production and processing device, particularly hardboard processing dryer.

Background technology

In hardboard is produced, paper the hardboard of compound production through multilayer, the compound back of multilayer paper is a kind of to be the nature airing, another kind is to use the tunnel type baking oven of electrical heating or coal gas heating to dry, be provided with the steel mesh conveyer belt in the tunnel type drying baker, paper the hardboard that compound back forms, be placed on the steel mesh conveyer belt and dry.The shortcoming of this tunnel type drying unit, the 1st, energy consumption is big, and electricity or coal gas heating-up temperature are at 160-170 ℃, and the tunnel is grown tens meters, and the space is big, and drying time is long, and energy loss is big.The 2nd, efficient is lower, owing to be to dry the hardboard that multilayer is formed by the compound back of paper, its speed of service is lower, need be controlled at the speed of per minute operation 8-10 rice, otherwise can't finish drying work.The 3rd, dangerous since be at high temperature, down action of low speed, once action is obstructed and need hinders clearly immediately, otherwise breaking out of fire accident is easily given birth to safe or unsafe.The 4th, of poor quality, cardboard is to be laid in to carry on the steel mesh belt under nature, and moisture content distributes slowly, and moisture content distributes does not have control, temperature is too high, and that hardboard heating surface moisture content is crossed is low and easy to be crisp frangible, hardboard drying course be heated inequality, inside and outside humidity inequality, hardboard is again in the raw, so be easy to produce bigger distortion, must carry out secondary reshaping, increase production cost, and the tightness of product, deflection, tensile strength, smoothness are relatively poor, product quality is relatively poor.The 5th, hardboard is that individual is placed on the conveyer belt, need manually carry out operation and send and get, and labour intensity is big, wastes time and energy.
