Abstract
The invention discloses a hot pressing machine for artificial boards. The hot pressing machine comprises a lifting mechanism, an upper pressing plate, at least one middle pressing plate, a lower pressing plate, an oil tank, a circulating pump, a temperature sensor, a cooling system and a controller; and an upper thermal-insulating partition plate is arranged between the upper pressing plate and the artificial board, a middle thermal-insulating partition plate is arranged between the middle pressing plate and the artificial board, and a lower thermal-insulating partition plate is arranged between the lower pressing plate and the artificial board. The hot pressing machine is characterized in that radiating and venting devices are respectively arranged between the upper thermal-insulating partition plate, the middle thermal-insulating partition plate, the lower thermal-insulating partition plate and the artificial boards. Due to the fact that the radiating and venting devices are respectively arranged between the upper thermal-insulating partition plate, the middle thermal-insulating partition plate, the lower thermal-insulating partition plate and the artificial boards, hot steam generated in processing can be quickly exhausted when thick boards more than 3cm are processed. Thus, gluing evenness and gluing firmness of the artificial boards are guaranteed, quick drying is achieved, the burst crack phenomenon is avoided, and the product quality is guaranteed.
Description
Technical field
The present invention relates to mechanical field, specifically, relate to a kind of man-made board hot-pressing machine.
Background technology
Hot press is one of most important equipment in Wood-based Panel Production, current hot press is fixedly mounted on by heating platen on the pressing plate framework of hot press, and heating platen is cavity structure, passes into the high temperature heat conductive oil of circulation during use in cavity, heating platen is heated, then carries out wood-based plate processing.At processing artificial boards, particularly when the wood-based plate of processing more than thickness 3cm, owing to being HTHP, can produce a large amount of hot vapour and can not discharge rapidly, wood-based plate there will be dry wet uneven, glues together uneven, insecure, can not dry fast, often occur the sheet material gummed loosely phenomenon of explosion, thus affect the quality of wood-based plate.Further, plate is thicker, and wet steam, the hot vapour of discharge are more, process more difficult.
Summary of the invention
In order to solve the problem existing for background technology, can hydrofuge steam discharge rapidly when the invention provides a kind of HTHP, wood-based plate can glue together even firm, and can by the man-made board hot-pressing machine of wood-based plate flash baking.
For achieving the above object, the technical solution used in the present invention: a kind of man-made board hot-pressing machine, comprise elevating mechanism, top board, at least one center platen, lower platen, fuel tank, circulating pump, temperature sensor, cooling system and controller, heat insulation dividing plate is provided with between top board and wood-based plate, heat insulation dividing plate in being provided with between center platen and wood-based plate, lower heat insulation dividing plate is provided with between lower platen and wood-based plate, it is characterized in that, respectively upper heat insulation dividing plate, in heat insulation dividing plate, be provided with heat dissipation ventilation device between lower heat insulation dividing plate and wood-based plate.
Preferably, described heat dissipation ventilation device is steel wire.
The present invention respectively upper heat insulation dividing plate, in heat insulation dividing plate, be provided with heat dissipation ventilation device between lower heat insulation dividing plate and wood-based plate, when processing the heavy-gauge sheeting of more than 3cm, promptly the hot vapour produced in process can be discharged, ensure that wood-based plate gummed evenly, firmly, and energy rapid draing, there will not be Decrepitation Phenomena, ensure product quality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is described in further detail:
A kind of man-made board hot-pressing machine comprises:
Elevating mechanism 5, it is connected with top board 1, center platen 2 and lower platen 3, and elevating mechanism 5 can control top board 1, center platen 2 and lower platen 3 and extrude wood-based plate, carries out hot-pressing processing, makes top board 1, center platen 2 and lower platen 3 depart from wood-based plate after having processed;
Top board 1, it is connected to the free end of described lift, and its inner homogeneous lays heat-conducting oil pipes and heating wire;
At least one center platen 2, it is connected with the free end of described elevating mechanism 5 and below described top board 1, its inner homogeneous lays heat-conducting oil pipes and heating wire;
Lower platen 3, it is connected to the free end of described elevating mechanism 5 and in the below of described center platen 2, its inner homogeneous lays heat-conducting oil pipes and heating wire.Between top board 1 and wood-based plate, be provided with heat insulation dividing plate, between upper heat insulation dividing plate and wood-based plate, be provided with steel wire 7; Heat insulation dividing plate in being provided with between center platen 2 and wood-based plate, in be provided with steel wire 7 between heat insulation dividing plate and wood-based plate; Between lower platen 3 and wood-based plate, be provided with lower heat insulation dividing plate, between lower heat insulation dividing plate and wood-based plate, be provided with steel wire 7.Heat insulation dividing plate is used for heat insulation, makes heating platen directly not contact with heatable soleplate thus damage heatable soleplate.When HTHP processing artificial boards, steel wire 7 is for hydrofuge steam discharge, and rapid draing, ensure wood-based plate bonding quality.
Fuel tank 4, it is connected by the heat-conducting oil pipes of transfer pipeline with described top board 1, center platen 2 and lower platen 3, oil-in and oil-out is respectively arranged with at the axial two ends of top board 1, center platen 2 and lower platen 3, conduction oil enters heating platen from the oil-in of one end of heating platen under the effect of circulating pump, then return fuel tank 4 from the other end oil-out of heating platen axis, recycle.
Circulating pump, it is connected with the transfer pipeline of described fuel tank 4, and the conduction oil made circulates in transfer pipeline.
Temperature sensor 6, it is arranged on described top board 1, center platen 2 and lower platen 3, for sensing the temperature of top board 1, center platen 2 and lower platen 3.
Cooling system, it, by heat exchanger and the heat exchange of cryogenic freezing water, makes described top board 1, and center platen 2 and lower platen 3 are lowered the temperature.
Electric heater unit, to the electric-heating-wire-heating in described top board 1, center platen 2 and lower platen 3 inside.
Controller, itself and described temperature sensor, cooling system and electric heater unit electrical connection, the required temperature of each heating platen is set in advance on the controller, when conduction oil flows through heating platen, temperature sensor 6 senses the temperature of each heating platen, temperature sensor 6 sends temperature signal to controller, controller is according to the temperature comparisons of received temperature signal with each heating platen pre-set, if the temperature signal that controller receives is higher than the preset temperature of certain heating platen, then controller starts cooling system, reduce the temperature of this heating platen, the temperature making this heating platen is identical with the temperature pre-set, if the temperature signal that controller receives is lower than the preset temperature of certain heating platen, then controller starts electric heater unit, raise the temperature of this heating platen, the temperature making this heating platen is identical with the temperature pre-set.
