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 5, 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 6 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 7 rerun, accept compression for the third time, the also pressurized roller 7 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 pressurization and heater of continuous calendar press, 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 utility model 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, wherein, several resin roll and warm-up mill are fan-shaped distribution and are pressed in main roller surface by steel band and constitute second level pressurized, heated mechanism.
The pressurization of described continuous calendar press and heater is characterized in that: the rotating shaft of resin roll and hot pressing roller is hinged by hydraulic cylinder and frame respectively.
Variable-frequency motor drives the driven roller rotation by reductor during the utility model work, drive the steel band motion by frictional force, steel strip driving idler roller, guide roller, main pressure roller, resin roll, hot pressing roller rotate, slab enters between steel band and the main pressure roller, under the effect of pressure and temperature, finish the curing of plastic deformation and adhesive, generate the product strip.
Good effect of the present utility model is: install resin roll and hot pressing additional and roll secondary pressurization, the heating arrangements that constitutes slab on main pressure roller, increase the time of the initial pressurized of slab, increased the high-density layer on surface, improved surface quality, increase allows the slab balance be heated to the input heat of steel band; Improve heart layer density, improve bond strength.The MOR of its production board of product of producing with respect to prior art improves 20%; Internal bond strength improves 25%; Can save 15-20kg glue; Enhance productivity more than 5%.
