Compared with prior art, the beneficial effects of the utility model are as follows:
The heat that when this utility model utilizes equipment operation, self produces carries out auxiliary heating and utilizes PTC heater to enter
Row actively heats the mode combined and effectively heats photosensitive resin.Actively heating uses PTC calandria, this calandria
Volume little, quick heating, even if PTC calandria temperature will be automatically stopped after reaching certain value during fan trouble；During heating not
Have combustion phenomena, safer, reduce the incidence rate of accident.This utility model makes the hot-air top from forming cavity dexterously
To lower flow, form reverse convection, controlled the operating of two kinds of mode of heatings by computer, make the heating of photosensitive resin more
Adding intelligence, when photosensitive resin needs heating, two kinds of mode of heatings work simultaneously, it is possible to rapidly photosensitive resin is heated to need
The temperature wanted；When reaching the temperature that photosensitive resin needs, actively heating stops, optionally open and close auxiliary mode of heating
Maintaining the temperature of photosensitive resin, the most energy-efficient, the homogeneous heating of photosensitive resin and heats are good, right during heating
The destructiveness of photosensitive resin is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of warm braw resin heating system described in the utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, below
In conjunction with detailed description of the invention, this utility model is expanded on further.
Seeing Fig. 1, a kind of warm braw resin heating system described in the utility model, including electrical control cabinet 2, forming cavity 1
With resin vallecular cavity 3.Being provided with resin storage tank 6 in resin vallecular cavity 3, the photosensitive resin liquid level of the opening of resin storage tank 6 connects with forming cavity 1
Touch.Electrical control cabinet 2 is a most airtight cabinet body structure, be provided with in electrical control cabinet 2 for control scraper motion and
The motor relevant to photosensitive resin solidification and control assembly.Forming cavity 1 and resin vallecular cavity 3 are located at the side of electrical control cabinet 2
Lower section.Forming cavity 1 is located at the top of resin vallecular cavity 3 and is connected to form airtight cavity with resin vallecular cavity 3.The surrounding of resin storage tank 6 is divided
Not and leave the gap of one fixed width between the cavity wall of the cavity wall of resin vallecular cavity 3 and forming cavity 1.Forming cavity 1 and electrical control cabinet 2
Between be provided with side passage and upper vent hole, side passage and upper vent hole are respectively arranged on sidepiece and the top of forming cavity 1, molding
