Background technology
Along with innovation and the fast development of rapid shaping and 3D printing technique, domestic a lot of company is surging to the research and development enthusiasm of 3D laser fast shaping, 3D printer based on photocuring is popularized gradually, due to the model of making towards deep processing operation difference, many manufacturers are making laser curing, 3D can utilize multiple photosensitive resin when printing, but the curing optimum temperature of different resins is different, and same resin is for different subsequent handlings, its curing temperature is also different, existing 3D printer or laser fast shaping machine have different mode of heatings, but all can not reach more intelligent, solidification effect more easily.
Summary of the invention
The utility model provides a kind of heater, and it can according to the actual requirements, control heating-up temperature, ensures the solidification effect of moulding material.
For achieving the above object, the utility model is taked following technical scheme:
Heater, comprises heating board, heating resistor and temperature controller, and described heating resistor is packaged on heating board by high temperature insulating material, the external thermocouple of described temperature controller, and described temperature controller is for controlling the operating state of heating resistor.
Further, also comprise relay, described relay is provided with normally opened contact, described temperature controller is provided with normally-closed contact, described temperature controller is connected with power supply as the first branch road, the normally-closed contact of described temperature controller is connected with power supply as the second branch road with after described relay series connection, and the normally opened contact of described relay is connected with power supply as the 3rd branch road with after described heating resistor series connection.
Further, described heating resistor is provided with several, after some described heating resistor parallel connections, connects with the normally opened contact of relay.
Further, also comprise contactor and the fuse often opened, described contactor is connected with the circuit after the first branch road, the second branch road, the 3rd branch circuit parallel connection after connecting with fuse.
Described heating board is provided with tray slot.
Described thermocouple is located at the edge of tray slot.
The disclosed heater of the utility model, by heating board, heating resistor and temperature controller control heating-up temperature, for different moulding materials and subsequent handling, also set temperature scope according to the actual requirements, improves the molding effect of moulding material.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model heating board;
Fig. 2 is the utility model electrical block diagram.
Embodiment
In order further to understand feature of the present utility model and technology contents, below in conjunction with accompanying drawing, content of the present utility model is described.
As depicted in figs. 1 and 2, the utility model discloses a kind of heater, comprise heating board 1, contactor 4, fuse FU, some heating resistors 2, thermocouple, temperature controller KT and relay K M, the external thermocouple of described temperature controller KT, described contactor 4 is normal open switch.
As shown in Figure 1, some described heating resistors 2 are packaged on heating board 1 by high temperature insulating material, and described heating board 1 is provided with tray slot 3, and thermocouple is located at the edge of tray slot 3.
Heating board is located at the metal tray bottom of storage material in 3D printer, described pallet is provided with retainer portion, described retainer portion is used for holding moulding material, as photosensitive resin, described retainer portion is located in the tray slot 3 of heating board 1, can reduce the thickness after pallet and heating board stack, also be conducive to heating board to pallet heat conduction, ensure the molding effect of moulding material.
As shown in Figure 2, described relay K M is provided with normally opened contact 6, described temperature controller KT is provided with normally-closed contact 5, described temperature controller KT is as the first branch road, the normally-closed contact 5 of described temperature controller KT connect with described relay K M after as the second branch road, the normally opened contact 6 of described relay K M is connected as the 3rd branch road with the heating resistor 2 after some parallel connections, after described contactor 4, fuse FU series connection, connect with the first branch road, the second branch road, the 3rd branch road after parallel connection, and connection and both ends of power.
According to moulding material and subsequent handling, the upper of temperature controller KT is set, lower limit temperature, connect contactor 4, relay K M obtains electric in the situation that of temperature controller KT normally-closed contact 5 closure, normally opened contact 6 closures of control relay KM, heating resistor 2 obtains electric, heat to heating board 1, be located at the thermocouple at tray slot edge for measuring the retainer portion temperature of pallet, measured temperature signal is sent to temperature controller KT by thermocouple, in the time that retainer portion temperature reaches the set ceiling temperature of temperature controller KT, temperature controller KT controls its normally-closed contact 5 and disconnects, relay K M dead electricity, the normally opened contact 6 of relay K M disconnects, heating resistor 2 dead electricity, pallet conducts heat and reduces temperature to external environment, in the time that temperature reaches the lowest temperature of temperature controller KT setting, temperature controller KT controls its normally-closed contact 5 closures, so circulation, be controlled to shaped material in certain temperature range.
The above execution mode is only used for illustrating the utility model, but is not limited to this.Do not departing under the condition of the utility model design; affiliated technical field personnel can make suitable change and adjustment; such as profile, size, selection, add tubing or other in the outside of this chuck mouth some be attached to function etc., and within these change and adjustments also should include claim protection range of the present utility model in.
