Description
Technical field
The present invention relates to one kind humidification and detection structure, mat formation especially suitable for medium-density plate and use on production line.
Background technology
Mat formation in medium-density plate on production line, exist because the problem of upstream process may result in shaping slab of mating formation
Metal impurities, as these metal impurities are joined into slab, hot-forming quality can be not only influenceed, more seriously follow-up
The damage of machine is caused in production, unnecessary economic loss is brought to production.
Pre-hardening thickness, i.e., the soft layer formed after usually said medium-density plate surface hot pressing, it is due to plate face adhesive
The weaker zone that premature cure is formed.In hot pressing, when slab not yet closes in pressing plate, acted on by heat, top layer
The moisture of material starts to evaporate, part adhesive condensation curing, forms the pre-hardening thickness of the relatively low conveying of density.Its presence,
Affect board surface quality and roughness.To ensure product quality, it is necessary to sanding processing is carried out to hot-forming fiberboard, this
Sample just causes the increase of production cost.
The heating-up temperature of pressing plate promotes the moisture vaporization in slab, increases the mobility of resin in adhesive, makes tree
Fat fully flows exhibition, disperses and penetrate between fiber, promotes resin rapid curing, by fibres bond together.Fibre in slab
Dimension moisture content is not high, although precompressed of the slab after mating formation by preformer, the slab entered in hot press still compare
Fluffy, thickness is still bigger, and slab is not only difficult to compress easy resilience, and heat conductivility is poor, and heating-up temperature is on slab thickness
There is gradient distribution, i.e. slab table, the sandwich layer temperature difference is big, so adds hot pressing time, reduces operating efficiency.
The content of the invention
The task of the present invention is to propose to whether there is metal impurities in a kind of on-line checking slab, in medium-density plate forming line
On steel slab surface is humidified, improve medium-density plate mat formation on production line humidification detection structure.
The task of the present invention, which is done in such a way that, is characterized in that：Spreading machine downstream is installed by strong magnets, the strong magnetic
Iron is to be spliced by the small rectangle strong magnets of bulk by the arrangement of N, S pole relative combinations, and strong magnets are fixed on by door frame
On conveyor support, metal induction alarm device is fixed on telescopic belt conveyor support by door frame, metal sensing report
The output signal of alert device, which is connected with controller after the telescopic belt for controlling downstream, is moved, and material is provided with below telescopic belt one end
Case, water lines are installed along above the conveyer belt of conveying slab, interval is provided with atomizer in the water lines, water lines with
External source is connected.The slab of carrying metallic impurities is closed up after falling to ash can by controller control telescopic belt reach,
The slab for transmitting not metal impurities enters downstream hot press hot pressing.
The present invention has the following effects that：The technical program is will to be mingled in spreading machine downstream by being provided with strong magnets
Iron adsorption in loose slab, slab through preformer precompressed, are delivered to hot press hot pressing, in order to improve slab by conveyer belt again
Moisture content, the technical program is provided with water pipe in loader upstream, steel slab surface is humidified, because moisture content is compared to wood
Heat transfer rate is fast for matter fiber, so not only reduces the thickness of density board slab pre-hardening thickness, while also shortens density
Pressing cycle in plate production process, so as to improve production efficiency.
Brief description of the drawings

Structural representation.
Drawing explanation：1st, spreading machine, 2, strong magnets, 3, metal induction alarm device, 4, telescopic belt, 5, ash can, 6,
Slab, 7, water lines, 8, atomizer, 9, conveyer belt.
Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
For specific embodiment as shown in figure 1, strong magnets 2 are installed in the downstream of spreading machine 1, the strong magnets are by the small of bulk
Rectangle strong magnets by N, S pole relative combinations arrangement be spliced, so making advantage be without so big high-intensity magnetic field, will not
The part operating on spreading machine is disturbed, strong magnets are fixed on conveyor support by door frame, as mixed in loose slab
Miscellaneous have an iron filings, and strong magnets are enough iron adsorption, and slab after Sawing machine cross cut saw, need to pass through metal and alarm through preformer precompressed
Device, metal induction alarm device 3 are fixed on telescopic belt conveyor support by door frame, the output letter of metal induction alarm device
Number it is connected with controller after the telescopic belt 4 in control downstream and moves, hopper 5 is provided with below telescopic belt one end, carries gold
The slab of category magazine is closed up after falling to ash can by controller control telescopic belt reach, transmits the plate of not metal impurities
Base 6 enters downstream hot press hot pressing, and in hot pressing, because slab thickness is big, poor heat conductivity, heating-up temperature is on slab thickness
There is gradient distribution, in order to ensure being fully cured for slab, reduces pre-hardening thickness thickness, it is necessary to augmentation of heat transfer, to shorten heat
Press the time.Therefore water lines 7 are installed along the top of conveyer belt 9 of conveying slab, interval is provided with atomizer in the water lines
8, water lines and external source are connected, and steel slab surface is humidified, and improves the moisture content of slab because moisture be compared to it is wooden
Heat biography speed is fast for fiber, thus it is very big in the effect for reducing steel slab surface humidity, it is pre- to not only reduce density board slab
The thickness of cured layer, while the pressing cycle in density board production process is also shortened, improve production efficiency.
In the present invention, unless otherwise clearly defined and limited, the art such as term " installation ", " connected ", " connection ", " fixation "
Language should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or integrally connected, can be two members
Connection inside part.For those skilled in the art, above-mentioned term can be understood the present invention's as the case may be
Concrete meaning.
