When spending height and being more than setting value or the second temperature detector 16 detects that the temperature of the workbench is excessively high and is more than
When setting value, the bottom plate cooler is started to work, and is cooled down to the bottom plate of the molding room 10, is passed through the side of heat transfer
Formula, and then the temperature of reduction by the 10 interior or described workbench of molding room.So that the temperature in the molding room 10 and institute
The temperature for stating workbench is maintained in desired temperature.
Referring to FIG. 1, in embodiment, there are two hand valve 33, one of two described hand valves 33 for setting on the circulating line
The filter 31 is set to close to the side of the molding room 10, two hand valves 33 are another to be set to the blasting unit
32 close to the side of the molding room 10.Two hand valves 33 are used to go out when the blasting unit 32 or the filter 31
When now abnormal, by the way that two hand valves 33 are turned off manually, remove the blasting unit 32 or the filter 31 is replaced
It changes or troubleshooting after loading onto the blasting unit 32 or the upper filter 31, then opens two after troubleshooting
A hand valve 33, when in the molding room 10 oxygen content and temperature reach the condition that can be printed when, continue not
The printing of completion.The setting of two hand valves 33, it is convenient the blasting unit 32 and the filter 31 are repaired and
It replaces, the protection gas also avoided in the molding room 10 excessively leaks, and needs to occur the case where refilling protection gas.
In embodiment, the outside of the molding room 10 is provided with the second oxygen content detector 17.Since printing device is general
It is positioned over interior, it is indoor if being continually fed into protection gas or the gas supply mechanism 20 leaks in the case that airfast
Oxygen content is likely lower than the normal value of needed by human body oxygen content, therefore the second oxygen content detector 17 is operated for detecting
Indoor oxygen content, when operating normal value of the indoor oxygen content less than needed by human body oxygen content, equipment sends out alarm, carries
Awake operating personnel take care, and avoid operating personnel and are chronically at low-oxygen environment.
Referring to FIG. 1, in embodiment, the gas supply mechanism 20 is connected by selector valve 24 with the admission line, institute
It states and is provided with multiple inlet channels on selector valve 24.By the way that multiple inlet channels are arranged, different protection gas gas supply can be connected
Mechanism 20 can be by selecting different inlet channels to be protected when different materials are replaced in printing needs different protection gas
The selection of gas gas supply mechanism 20, is conveniently operated, and eliminates the step of replacing gas supply mechanism 20, saves the working time.This implementation
In example, the quantity of the inlet channel is 3.
In embodiment, flowmeter 25 is provided on the admission line, the flowmeter 25 is set to the control valve 21
Close to the side of the gas supply mechanism 20.The flowmeter 25 can when equipment works normally, cumulative calculation this be printed as
The gas that product are consumed facilitates the loss of control gas and cost control to calculate.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
