Description
[technical field]
The utility model belongs to the man-made board technology field, is specifically related to a kind of man-made board hot-pressing machine with spray steaming and vacuum system.
[background technology]
In the prior art, the process for making of wood-based plate is if will shorten the time of production of articles process, and key is how effectively to shorten hot pressing time.The speed that heat transmits in the hot pressing directly influences the slab central core and reaches the needed time of adhesive solidification temperature, thereby influence hot pressing time and product quality, and therefore, the transmission of heat and the distribution of temperature become the place of the focus that heat pressing process controls.At present, because wood-based plate adopts string as raw material, string is non-hot good conductor, and heat transfer rate is slow, so traditional heat pressing process easily forms slab thickness direction non-uniform temperature by contact conduction mode of heating, hot pressing time is long and quality is also unstable.
How to shorten the hot pressing time of wood-based plate in the prior art and then improve the production rate and quality has become problem demanding prompt solution in the art.
[utility model content]
In order to solve the existing above-mentioned deficiency of the manufacturing process of wood-based plate in the prior art, the utility model purpose is to provide a kind of man-made board hot-pressing machine with spray steaming and vacuum system.
For achieving the above object, the technical scheme that one of the utility model embodiment is provided is: a kind of spray is steamed, the vacuum hotpressing machine, comprise a hot press body and the conduction oil electric heater that joins by pipeline and hot press body, spray is steamed, the vacuum hotpressing machine more comprises a steam generator and a vacuum system, steam generator and vacuum system all are connected with the hot press body by a steam pipeline system, steam generator is used to produce high-temperature water vapor and passes to the heat pressing process time of hot press body with the shortening heat press by steam pipeline system, and vacuum system is used for the condensed steam after the heat pressing process end is taken out to reduce the moisture content at slab center.
One of the utility model embodiment provides spray steaming, vacuum hotpressing machine, wherein, vacuum system is made up of vavuum pump, vacuum tank, moisture trap, aerial cooler, aerial cooler directly links to each other with steam pipeline system, and aerial cooler, moisture trap, vavuum pump are connected with vacuum tank respectively.
Based on the design of the foregoing description, advantage of the present utility model is:
(1) hot pressing time is short, hot pressing time be the general conventional hot-press process time 1/5～1/10, boost productivity;
(2) almost on whole slab thickness, carry out simultaneously because of heating, so it is very even to become the plate profile density to distribute;
(3) sanding amount is little, can prevent that the plate face from producing precuring, only needs the sanding of plate veil trace can energy consumption lowly, and uperize heating in slab only is about 30% of conventional hot-press plate heating institute heat dissipation energy;
(4) to various existing adhesive, all be suitable for as Lauxite, phenolic resins, melamine urea-formaldehyde resin, isocyanate resin etc.Can also make into the burst size of methanal decrease to some degree of plate.
One of the utility model embodiment provides the automatic control system of spray steaming, vacuum hotpressing machine to adopt industrial computer and PLC, configuration software with VB language independent development operating system, it is applicable to the new product development of artificial board enterprise, decoration industry, the product processes test, and be used for universities and colleges, the breadboard research and teaching in scientific research institution.
Other purposes of the present utility model and advantage can be further understood from the disclosed technical characterictic of the utility model.State with other purposes, feature and advantage and can become apparent on the utility model for allowing, embodiment cited below particularly also cooperates appended graphicly, is described in detail below.
[description of drawings]
Fig. 1 is the spray steaming of an embodiment of the present utility model, the structural representation of vacuum hotpressing machine.
[specific embodiment]
About addressing other technologies content, characteristics and effect before the utility model, in the following detailed description that cooperates with reference to graphic embodiment, can clearly present.The direction term of being mentioned in following examples, for example: upper and lower, left and right, front or rear etc. only are the directions with reference to annexed drawings.Therefore, the direction term of use is to be used for illustrating not to be to be used for limiting the utility model.
Referring to shown in Figure 1, a kind of spray steaming, vacuum hotpressing machine 1 that one of the utility model embodiment provides, comprise a hot press body 14 and the conduction oil electric heater 13 that joins by pipeline (figure does not show) and hot press body 14, spray is steamed, vacuum hotpressing machine 1 more comprises a steam generator 11 and a vacuum system 12, and steam generator 11 and vacuum system 12 all are connected with hot press body 14 by a steam pipeline system 15.
Among one of the utility model embodiment, vacuum system 12 is made up of vavuum pump 123, vacuum tank 122, moisture trap 124, aerial cooler 121, aerial cooler 121 directly links to each other with steam pipeline system 15, and aerial cooler 121, moisture trap 124, vavuum pump 123 are connected with vacuum tank 122 respectively.
The spray steaming of one of the utility model embodiment, the operation principle of vacuum hotpressing machine 1 are earlier by the 13 pairs of slab contacts conduction heating of conduction oil electric heater system, when slab is compressed to after density is 0.4～0.5g/cm3, directly spray slab with what steam generator 11 provided by the spray steaming hole (figure does not show) of (figure does not show) on the steaming of the spray on the hot press body 14 plate, make about 150 ° of the temperature that thicker slab central temperature solidifies near sizing material rapidly, thereby slab top layer and central core with big thickness are solidified simultaneously, shortened pressing cycle greatly, boosted productivity.After slab spray is steamed, treat the temperature balance after, then carry out the negative pressure suction by 12 pairs of slabs of vacuum system, take out partial condensation steam, reduce the moisture content at slab center, be conventional hot-press technical process such as high and low pressure pressurize and step-down then.
Though the utility model discloses as above with preferred embodiment; so it is not to be used for limiting the utility model; anyly have the knack of this skill person; in the spirit and scope that do not break away from the utility model; when can doing a little change, so the protection domain of the utility model is as the criterion when looking the patent protection scope person of defining.In addition, arbitrary embodiment of the present utility model or claim must not reached whole purposes or advantage or the characteristics that the utility model discloses.In addition, summary part and title only are the usefulness that is used for assisting the patent document search, are not the rights protection scope that is used for limiting the utility model.
