A kind of production equipment of embossment Surface decorated woodbased panels with paper impregnated thermosetting resins
Technical field
The utility model relates to sheet material manufacture field, is specifically related to a kind of production equipment of embossment Surface decorated woodbased panels with paper impregnated thermosetting resins.
Background technology
At present, high relief Surface decorated woodbased panels with paper impregnated thermosetting resins has match volume effect, and special profile structure, liked by people, but existing 2mm deep relief artistic is also immature in the market.Below normal employing melamine facing paper, add some layers of brown paper, and to base material medium density fibre board (MDF) with ammoniacal liquor soften process method, be 290-300 ℃ in temperature, pressure 2.0-2.4MPa, hot pressing time is under 40-60s condition, and the chemical substance in fiber softening and wood-fibred is flowed, and relief die is pressed in pressurized sheet material, keep pressure until wood-fibred solidifies and reaches required relief depth 2mm, thereby guarantee the effect that embossment overlays.Embossment steel form is darker because of texture, and profile is the irregular texture patterns such as imitative wood grain, bad because of the melmac stream malleability in bond paper in hot pressing subsides process, causes local grain position to occur dried flower defect, and match volume effect is poor.
Also have following shortcoming:
1, operation is more, not easy to operate.Below facing paper, add brown paper, and base material is carried out to the softening processing of ammoniacal liquor, increased operation, increased the difficulty of operation simultaneously.Production cost increases.In production process, increase the raw material such as brown paper, ammoniacal liquor, increased cost of raw material input.
3, energy resource consumption is large.Hot pressing temperature is 290-300 ℃, requires temperature higher, causes the quantity of energy consuming to increase, and has also caused the increase of cost.
4, production efficiency is low.Hot pressing time is 40-60s, and it is long that the more conventional short period overlays the time, affects production efficiency.
Summary of the invention
The utility model object is to provide a kind of production equipment of embossment Surface decorated woodbased panels with paper impregnated thermosetting resins, the immature decoration panel product that causes of technique that solves high relief is prone to dried flower open defect, can not realize the problem of the match volume effect of Surface decorated woodbased panels with paper impregnated thermosetting resins.
A kind of production equipment of embossment Surface decorated woodbased panels with paper impregnated thermosetting resins, comprise into plate transmission device and hot press, described enter plate transmission device output connect hot press, described hot press has top board and lower platen, described hot press is provided with time controller and the temperature controller for heating.Under the condition that 190 ℃ of hot pressing temperatures of control, hot pressing time are 35s, complete overlaying of embossment Surface decorated woodbased panels with paper impregnated thermosetting resins.
In described hot press, be provided with dark wood grain embossment Stainless Molding Board, described dark wood grain embossment Stainless Molding Board surface is provided with many dimpled grain grooves.Can need to regulate according to design the degree of depth of dimpled grain groove, such as being 2mm, or 1mm, meet different customer requirements.
The following advantage that the utility model has compared with the prior art:
1, process operations aspect.Adopt conventional dipping face artificial board operation, and prior art increases raw material material operation.
2, production cost aspect.Compared with the prior art, do not adopt the raw material such as brown paper, ammoniacal liquor, this part cost of raw material does not increase.
3, energy resource consumption aspect.Adopt temperature controller, control 190 ℃ of hot pressing temperatures, adopting hot pressing temperature than prior art is 290-300 ℃ low, lower to energy device requirement, and energy resource consumption is less.
4, production efficiency aspect.Adopt time controller, controls hot pressing time is 35s, is that 40-60s is short than prior art employing hot pressing time, is conducive to enhance productivity, and realizes the short period to overlay production.
Accompanying drawing explanation
Fig. 1 is the production equipment structural representation of a kind of embossment Surface decorated woodbased panels with paper impregnated thermosetting resins of providing of the utility model embodiment.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.
The production equipment of a kind of embossment Surface decorated woodbased panels with paper impregnated thermosetting resins that the utility model provides, as shown in Figure 1, comprise into plate transmission device 1 and hot press 2, described enter plate transmission device output connect hot press, described hot press has top board 21 and lower platen 22, and described hot press is provided with time controller 3 and the temperature controller 4 for heating.Under the condition that 190 ℃ of hot pressing temperatures of control, hot pressing time are 35s, complete overlaying of embossment Surface decorated woodbased panels with paper impregnated thermosetting resins.The utility model has the advantages that hot pressing temperature is low, hot pressing time is short, reaches energy resource consumption few, the effect of enhancing productivity.
