Abstract
The utility model discloses an anti-edge-warping heating plate structure for a constant-temperature 3D printer. The structure comprises a heating layer arranged in the 3D printer, wherein a heat conducting flat plate is fixed on the heating layer in an adhering manner; the heating layer adopts a flexible PTC heating film which comprises a silica gel outer cover, and a plurality groups of PTC ceramic thermister chips and aluminium strips distributed in the silica gel outer cover in a matrix manner; the aluminium strips are placed on the upper sides and the lower sides of the PTC ceramic thermister chips, are in full contact with the silica gel outer cover, and are connected with the PTC ceramic thermister chips through conducting resin; every two adjacent PTC ceramic thermister chips are the same in the mounting height in the silica gel outer cover. Compared with the prior art, the structure adopts the flexible PTC heating film as the heating layer for the 3D printer, thereby having an excellent constant-temperature characteristic, and the temperature difference problem in the prior art is eliminated, the printing effect is improved, and moreover, the whole structure is simple and is convenient for operation.
Description
Technical field
The utility model relates to 3D printer field, is specially the anti-alice heating board structure of constant temperature 3D printer.
Background technology
Existingly take the 3D printer that plastics are printed material, in printing because temperature official post printed material in temperature of heating plate and air has flexural deformation to a certain extent, and existing heating plate and plastics printed material concretion technology imperfection, only adopting high temperature resistant adhesive tape is the problem that cannot avoid printed material alice.In practice process, most of user avoids alice problem with printing in advance gripper shoe, although the method can be avoided alice problem, and the extremely out-of-flatness of finished product bottom surface of printing.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-alice heating board structure of constant temperature 3D printer, solves in printing because temperature official post printed material in temperature of heating plate and air has diastrophic problem to a certain extent.
For achieving the above object, the utility model provides following technical scheme:
The anti-alice heating board structure of constant temperature 3D printer, comprises the zone of heating of being located in 3D printer, and on zone of heating, laminating is fixed wtih a heat conduction flat board; Described zone of heating is a flexible PCT heating film, described flexible PCT heating film comprises silica gel outer, some groups of PTC ceramic thermistor core sheets and aluminium strip, the equal matrix distribution of PTC ceramic thermistor core sheet and aluminium strip is in described silica gel outer, aluminium strip is placed in the both sides up and down of PTC ceramic thermistor core sheet, aluminium strip contacts completely with silica gel outer, aluminium strip is connected by conducting resinl with PTC ceramic thermistor core sheet, and the setting height(from bottom) of two PTC ceramic thermistor core sheets of arbitrary neighborhood in silica gel outer is identical.
Preferably, the dull and stereotyped employing of described heat conduction is Na2OCaO6SiO2 glass plate.
Compared with prior art, compared with prior art, the utility model adopts flexible PCT heating film as the zone of heating of 3D printer, its excellent thermostatic characteristics has been eliminated the temperature difference problem occurring in prior art, improve printing effect, and total is simple, convenient operation.
Accompanying drawing explanation
Fig. 1 is the structural representation that dissects of the present utility model.
In figure: 1-heat conduction is dull and stereotyped, 2-zone of heating, 2a-silica gel outer, 2b-aluminium strip, 2c-PTC ceramic thermistor core sheet.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
The anti-alice heating board structure of constant temperature 3D printer as shown in Figure 1, comprises the zone of heating 2 of being located in 3D printer, and on zone of heating 2, laminating is fixed wtih a heat conduction flat board 1; Described zone of heating 2 is a flexible PCT heating film, described flexible PCT heating film comprises silica gel outer 2a, some groups of PTC ceramic thermistor core sheet 2c and aluminium strip 2b, PTC ceramic thermistor core sheet 2c and the equal matrix distribution of aluminium strip 2b are in described silica gel outer 2a, aluminium strip 2b is placed in the both sides up and down of PTC ceramic thermistor core sheet 2c, aluminium strip 2b contacts completely with silica gel outer 2a, aluminium strip 2b is connected by conducting resinl with PTC ceramic thermistor core sheet 2c, and the setting height(from bottom) of two PTC ceramic thermistor core sheet 2c of arbitrary neighborhood in silica gel outer 2a is identical; What described heat conduction dull and stereotyped 2 adopted is Na2OCaO6SiO2 glass plate, and Na2OCaO6SiO2 glass plate has extraordinary heat conductivility.
PTC ceramic thermal resistance is the semiconductor resistor that a kind of typical case has temperature sensitivity, while surpassing certain temperature, its resistance value is along with the rising of temperature is increasing of step evolution, now, due to its resistivity-temperature characteristics, electric current reduces along with the increase of resistance, when resistance value reaches maximum, PTC chip no longer generates heat, and temperature no longer rises.Aluminium has conduction, heat conduction characteristic rapidly and uniformly, adopt aluminium strip as conduction, heat-conducting medium, optimized the performance of PTC heating film, owing to self thering is the characteristic of insulation in common silica gel, add existing heat-conducting filler, make it possess the dual property of insulation, heat conduction, safe and reliable, in the utility model, the use of PTC ceramic thermal resistance makes 3D printer obtain heating part all the time in temperature constant state, has so just eliminated the situation that causes printed material perk distortion because of heating part difference variation.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limiting related claim.
