Description
Technical field
The utility model relates to the hot press of producing finger-jointed sheet material in the wood-based plate processing, relates in particular to a kind of quick plate splicing hot press of producing finger-jointed sheet material.
Background technology
In the technology of existing production finger-jointed sheet material, the jigsaw of finger-jointed plate, pressurization, curing mainly contain three kinds:
1, adopts white glue with vinyl, the cold press pressurization; Because white glue with vinyl belongs to normal temperature cure glue, hardening time is longer, approximately needs about 5 hours.
2, adopt urea-formaldehyde glue, the hot press pressurization; Urea-formaldehyde glue belongs to heat-curable glue, and more than 105 ℃ the time, only need 60～90 seconds hardening time.The hot press that adopts at present is multilayer, is generally 6～10 layers, is with 2 side pressure oil cylinders for every layer, for example disclosed a kind of structural finger-jointed sheet material of China Patent No. " CN200910207202.2 " and manufacture craft, and open day is on 04 07th, 2010.
3, adopt special-purpose splicing adhesive, with the high-frequency microwave heating, need about 2～3 minutes hardening time, and press is individual layer.
Adopt above three kind of method of producing finger-jointed plate, the problem of existence is:
1, first method; Because the hardening time of white glue with vinyl is longer, and the finger-jointed plate jigsaw must solidify under the state of pressurization, so production efficiency is low, and the price of white glue with vinyl also wants high than urea-formaldehyde glue.So just directly brought the higher problem of production cost.
2, second method; Although adopt urea-formaldehyde glue, hot press pressurization, reduced the cost with glue, shortened hardening time.But in order to enhance productivity, the hot press that adopts at present is multilayer, is generally 6～10 layers, every layer of band side pressure oil cylinder.When work, every one deck of glue-coated finger batten being put into hot press is combined into tabular, the lower oil cylinder that starts hot press rises, and the lower bolster in the jack-up hot press and heating platen rise, but every liter of one deck just stops, the side pressure oil cylinder that starts this layer adds side pressure, so incremental, what expend is the time, and be very short the hardening time of urea-formaldehyde glue, when hot press rose one deck and stops being raised to, the glue that is coated with on which floor finger-jointed plate above in the hot press had all solidified or has arrived the last stage of solidifying.Like this, seriously affected the bonding quality of finger-jointed plate, and production efficiency is also relatively on the low side.
3, the third method; Owing to being to adopt the high-frequency microwave heating, need to be placed on a relatively rectangular box internal heating curing of sealing with piecing together good slab.So can only be individual layer.And the price of special-purpose splicing adhesive is 5～7 times of urea-formaldehyde glue.
Summary of the invention
