Description
Technical field
The utility model relates to the integral type of the printhead of three-dimensional printer, particularly three-dimensional printer and divides flow heat dissipation printhead.
Background technology
Conventionally in print procedure, the printhead of three-dimensional printer need to be heated to 190-230 DEG C, in order not affect the normal work of extruder motor, need a radiator constantly to dispel the heat (horizontal direction) facing to extruder motor direction, need fin as auxiliary because caloric value is huge.On the other hand because three-dimensional printer adopts the mode that material is manufactured that increases substantially, in print procedure, if one deck print complete do not obtain cooling timely, very easily cause printhead to pull in motion process and cause distortion, therefore need a radiator to carry out ventilation and heat (vertical direction) from printing the backward printer model of beginning.
Prior art is for can better thus increasing heat radiation effect, adopts two even many cooling systems of cooling system more, for example, Makerbot adopts two cooling systems, one adopts the higher turbofan of power, blows to print platform, and another radiator fan blows to extruder motor; Ultimaker adopts three cooling systems, and two radiator fans blow to print platform, and a radiator fan blows to extruder motor.Cause like this preponderance of printhead, make to control two motor overloads of x axle and the motion of y direction of principal axis.The printhead of two cooling systems or many cooling systems takies large quantity space on the other hand, has in a disguised form reduced moulding volume, causes space availability ratio to reduce.
Because three-dimensional printing technology is at the early-stage, especially desktop small-sized three-dimensional printing technique just entered the popular visual field at nearly 3 years, corresponding know-why is far from reaching the stage of ripeness, corresponding printhead dependency structure is only divided into two kinds foundation structure principle: first extruder motor is near printhead portion, advantage is that extruder motor moment of torsion is little, extrude situation comparatively stable, shortcoming causes printhead overweight, and print speed slows down; It two is that extruder motor and printhead motion parts depart from, and alleviates printhead weight print speed is brought up to 150mm/s, and shortcoming, because extruder motor is excessively far away apart from extruder head, requires extruder motor to have larger moment of torsion to complete discharging.
The utility model is ensureing that original radiating effect meets the requirements of on basis, to reduce the formal space of printhead and printhead weight as basic object.
Utility model content
In view of the foregoing defects the prior art has, in order to ensure that original radiating effect meets the requirements of on basis, increase print area and print speed with the formal space and the printhead weight that reduce printhead, the utility model provides the integral type of three-dimensional printer to divide flow heat dissipation printhead, comprise radiator fan, fin, feed arrangement, extruder motor, charging trunnion, plectrum keeps out the wind, the extruder head joining with charging trunnion, thermistor and heating head on the heating aluminium block of parcel extruder head and heating aluminium block, fin is connected with charging trunnion with extruder motor, radiator fan is relative with fin position and be fixed on fin by screw, on fin, in the vertical direction is provided with unidirectional chute, the plectrum that keeps out the wind is positioned at the front of heating aluminium block, be fixed on fin by four stay bolts.
The integral type of the disclosed three-dimensional printer of the utility model is divided in the embodiment of flow heat dissipation printhead, and wherein the quantity of radiator fan is one.
The integral type of the disclosed three-dimensional printer of the utility model is divided in the embodiment of flow heat dissipation printhead, and wherein the direction of unidirectional chute is downward.
The integral type of the disclosed three-dimensional printer of the utility model is divided in the embodiment of flow heat dissipation printhead, by add unidirectional chute in fin, originally the wind blowing out for the radiator fan of extruder motor heat radiation is done to a part of water conservancy diversion, a part of air-flow by horizontal direction guides vertical direction, again by the plectrum that keeps out the wind by wind concentration at printer model place, thereby when realizing the heat radiation of extruding motor radiating sheet, complete the heat radiation to print platform.
Beneficial effect
The integral type of the disclosed three-dimensional printer of the utility model divides flow heat dissipation printhead to have following advantage: by add unidirectional chute in fin, can ensure original radiating effect with a radiator fan; Only, with a radiator fan, increase print area, improved the printing effect of complete machine; Only, with a radiator fan, reduce the weight of printhead, alleviated the load of motor, thereby reached more stable printing effect and print speed faster.
