Abstract
The invention discloses a continuous calendar press with a flexible hot pressboard. A drive roll, a tension roll and a guide roll are supported and distributed on a frame in triangle shape. A master press roll is arranged between the drive roll and the guide roll. The master press roll and the guide roll form a primary pressurization mechanism of a plate blank. An annular metal strip covers the master press roll, the drive roll, the tight roll and the guide roll sequentially to form a circular closed heat conduction transmission mechanism. The metal strip drives each roll to rotate and heat up and pressurize the plate blank. The flexible hot pressboard covers the outer side of the metal strip. A plurality of hydraulic cylinders are distributed at the outer side of the hot pressboard. Pressure and heat are transferred to the metal strip by a roller blanket. The temperature, pressure and displacement applied to the plate blank can be adjusted according to the requirement of the plate-making technology. The invention can adjust the density distribution of the plate blank along the direction of the thickness conveniently, increases a high-density layer on the surface, improves the surface quality, increases the heat input to the metal strip and ensures that the plate blank is heated evenly, and the invention also improves the density of a core layer and bonding strength.

Background technology
The structure of the existing continuous rolling formula hot press that is used to produce medium-density plate and particieboard and principle are as shown in Figure 1.The slab of middle density or particieboard is entered between main pressure roller and the steel band by feeding belt, under the pressure of guide roller, be compressed, i.e. compression for the first time, the two sides begins to accept to come respectively the heat of autonomous pressure roller and steel band simultaneously, arrive backer roll after moving about three meters, accept compression for the second time, steel band also pressurized roller heating this moment, about two and half back arrival backer rolls rerun, accept compression for the third time, the also pressurized roller of steel band heats once more, and slab is being coated with main pressure roller by steel band and moving to outlet generation finished product strip.When this hot press was used to produce, technology existed following defective and is: compression time is short for the first time, and the high-density layer of steel slab surface as thin as a wafer; The shortage of heat of steel band self deposit is not though satisfy the demand of slab to heat through twice heating of backer roll; Can not get compression when slab heart layer temperature reaches softening point, heart layer density is low, and internal bond strength is low.
Summary of the invention
The invention provides a kind of continuous calendar press that has flexible hot pressboard, solved the steel band deposit shortage of heat that existing hot press exists, can not satisfy the normal production requirement of follow-up slab and when slab heart layer temperature reaches softening point, can not get compression, shortcomings such as heart layer density is low, and internal bond strength is low.
Technical solution of the present invention is as follows: driven roller on frame, idler roller, guide roller support distribution triangular in shape, driven roller is connected with reductor, drive by variable-frequency motor, main pressure roller is arranged between driven roller and the guide roller, main pressure roller and guide roller constitute the first order pressing mechanism of slab, be provided with the conduction oil passage in the housing of main pressure roller, roll surface is provided with middle height, the steel band of annular is coated on main pressure roller in proper order, driven roller, idler roller, constitute the heat conduction transmission mechanism of circulation sealing on the guide roller, each roller turn of steel strip driving, heat is passed to slab, tension force with self pressurizes to slab between main pressure roller, it is characterized in that: the flexible hot pressboard inside of arcuation is provided with the conduction oil passage, by the roller blanket, steel band fixedly is pressed in main roller surface and constitutes pressurized, heated mechanism, several hydraulic cylinders divide two groups of close entrance and exit positions that are pressed in heating platen respectively, the inlet of heating platen is by the angle of hydraulic cylinder and the hinged adjusting inlet of frame, the outlet of heating platen is hinged by hydraulic cylinder and frame, by the pressure between hydraulic coupling adjusting heating platen and main pressure roller; The roller blanket is by some roller bars and chain looping banded structure, roller blanket drive sprocket by the heating platen outlet is connected with the deceleration variable-frequency motor, be located between heating platen and the steel band, transmit heat and pressure between heating platen and steel band, pneumatic tensioning device withstands on the tension force of the inboard dancer rools blanket of chain.
Variable-frequency motor drives the driven roller rotation by reductor during work, drives the steel band motion by frictional force, steel strip driving idler roller, guide roller, main pressure roller, the operation of roller blanket.Slab enters between steel band and the main pressure roller, according to the pressure and the displacement of arts demand adjusting heating platen hydraulic cylinder, finishes the curing of plastic deformation and adhesive under the effect of pressure and temperature, generates the product strip.
Good effect of the present invention is: adopt flexible hot pressboard that steel band is heated, slab is accepted continuous pressurization in press, and can regulate the pressure of pressure area arbitrarily, has satisfied the needs of mask-making technology, has reached the effect of continuous flat.Increase the high-density layer of product surface, improve surface quality, increase input heat, allow the slab balance be heated steel band; Improve heart layer density, improve bond strength.The MOR of the finished product plate of producing with respect to prior art improves 30%, and internal bond strength improves 50%, can save 40kg glue, enhances productivity more than 5%.
