Abstract
The invention relates to the field of a flat plate type continuous press, in particular to a control method of the flat plate type continuous press. When a plate blank has a certain tilting value, the average thickness of the plate blank is compared with a preset thickness, so the average thickness of the plate blank achieves the preset value. Because a left pressure preset value and a right pressure preset value are the value obtained by multiplying a middle pressure value with a left pressure coupling coefficient and a right pressure coupling coefficient, the preset pressure at the thicker side of the plate blank is larger than the preset pressure at the thinner side of the plate blank, so the tilting value of the plate blank can be properly reduced. Compared with pressure control of the background technology, the tilting condition of the plate blank is improved, and compared with position control of the background technology, the density of each part of the plate blank is more uniform, the heat transfer condition is better, the internal colloid curing condition is better, and then the quality of processed artificial plates is improved.
Description
Technical field
The present invention relates to plate of plate continuous press field, more particularly, relate to a kind of control device of plate of plate continuous press.
Background technology
Wood-based plate is the important materials of the industry such as building decorating industry, upholstery, conventionally uses plate of plate continuous press to process wood-based plate at present at industry of artificial boards.Plate of plate continuous press comprises pressing plate, and slab thickness under the squeezing action of pressing plate, by thick attenuation, reaches predetermined value.
The pressing plate squeezing action of prior art middle plateform formula continuous press is by HYDRAULIC CONTROL SYSTEM.A hydraulic system comprises a left side, in, right three oil pressure cylinder (left oil pressure cylinders, middle oil pressure cylinder and right oil pressure cylinder) and left, in, right three electric-controlled hydraulic control valve (left electric-controlled hydraulic control valves, middle electric-controlled hydraulic control valve and right electric-controlled hydraulic control valve), left electric-controlled hydraulic control valve is connected on the oil circuit of left oil pressure cylinder, control the flexible of left oil pressure cylinder, middle electric-controlled hydraulic control valve is connected on the oil circuit of middle oil pressure cylinder, in control, oil pressure cylinder is flexible, right electric-controlled hydraulic control valve is connected on the oil circuit of right oil pressure cylinder, control the flexible of right oil pressure cylinder, these three oil pressure cylinders are directly controlled moving up and down of pressing plate, three of left, center, right oil pressure cylinder can, by pressure control, also can pass through Position Control, so-called pressure control is that three of left, center, right oil pressure cylinder is separately with the control of pressure mode, so-called Position Control is at the installation position, the left and right sides of pressing plate displacement sensor, the thickness of platen edge or slab can be detected, according to the stroke of left and right two oil pressure cylinders of the THICKNESS CONTROL of detected platen edge or slab, and due to condition restriction, the oil pressure cylinder inconvenience installation position displacement sensor in centre position, so the oil pressure cylinder in centre position adopts pressure control, the setting of its predetermined force value can be associated with the force value of arranged on left and right sides.Because the length of slab is longer, conventionally in the length direction of pressing plate several above-mentioned hydraulic systems that can distribute, the hydraulic system of ordinary circumstance feed end can be set to pressure control, the hydraulic system of discharge end can be set to Position Control, and the thickness of the finished product sheet material of being produced to ensure meets pre-provisioning request.
In production and processing, the difference of the factor such as the thickness of the slab raw material often being come, wooden, glue used, all needs again to set respectively the predetermined value of each hydraulic system to every batch of slab, thereby causes the processed complex of wood-based plate, working (machining) efficiency lower; The slab raw material that normal conditions are come everywhere thickness to some extent difference be that left and right sides has certain tilting value, taking a hydraulic system as example, in the time of pressure control, three of left, center, right oil pressure cylinder reaches after predetermined force value, the stroke difference of three oil pressure cylinders, therefore, now cannot improve the inclination situation of slab; In the time of Position Control, the elongation of left and right two oil pressure cylinders reaches predetermined value, the distortion at the position that now slab is thicker is larger, the position deflection that slab is thinner is less, thereby just cause the each position of slab Density inhomogeneity, and that the larger position of the decrement position heat transmission situation less compared with decrement is poor, colloid is solidified situation in slab is poor, and then just cause processed wood-based plate second-rate.
Therefore, how to improve slab inclination situation, to improve the quality of wood-based plate be the current technical issues that need to address of those skilled in the art.
