Description
Technical field
The utility model relates to a kind of 3D printhead, particularly a kind of printhead of 3D printer.
Background technology
The printing type of current main flow is by printer by reading the cross sectional information of the product prestored, and then printed layer by layer in these cross sections with the raw material melted, raw material adopt thread material or a bar etc. usually.
Silk material is made up of pure plastics, can the limited material of wire drawing, and virgin material can not add additive, thus 3D printed product material being had to requirement can not be met, thus the bar that adopts prints more now, bar is thick, multiple additives can be added (as glass, nano ceramic powder etc.), formed and there is specifically functional composite, washability is large, even metal material can be adopted, the high request of 3D printed product to material can be met, in order to bar be made smooth in the process printed, send into equably in smelting furnace, the applicant has done new design for the feed mechanism in printhead.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of bar that makes to send into printhead in smelting furnace smoothly, equably.
The utility model solves the technical scheme that its technical problem adopts:
A kind of printhead of 3D printer, comprise handpiece case, it is characterized in that: described handpiece case top is provided with the hand-hole sent into for bar, be provided with for portalling of sending of bar bottom handpiece case, and handpiece case is fixed with drive motors, the power output shaft of described drive motors is fixed with driven wheel, described handpiece case is provided with the top-pressure mechanism of swing arm and top pressure swing arm, this swing arm and handpiece case are rotationally connected, and one end of this swing arm is provided with rotating pinch roller, by the pressure swing arm of top-pressure mechanism top, the gear teeth of extruded bar stock and driven wheel tightly touch described pinch roller.
Described top-pressure mechanism comprises screw rod and is arranged at the screw on handpiece case, and described swing arm is pressed by the top of screw rod.
On described screw rod, cover has Compress Spring, and one end of Compress Spring contacts with swing arm and the nut of another side and screw rod is conflicted.
Described pinch roller have employed U-shaped bearing or V-arrangement bearing.
Described handpiece case top is provided with feeding pipe, and described hand-hole is the endoporus of feeding pipe; Be provided with discharge nozzle bottom described handpiece case, described in portal for the endoporus of discharge nozzle.
The beneficial effects of the utility model are: the gear teeth that the utility model adopts the pressure swing arm of top-pressure mechanism top to make pinch roller compress bar and driven wheel tightly touch, thus increase the frictional force of bar and the gear teeth, at driven wheel, bar is sent in the process of smelting furnace, can not skid, and stable movement, thus ensure that nozzle goes out the uniformity of the raw material of the fusing of ejection, thus ensure that print quality.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is topology view of the present utility model.
Detailed description of the invention
With reference to Fig. 1, the utility model discloses a kind of printhead of 3D printer, comprise square handpiece case 1, described handpiece case 1 top is provided with feeding pipe 2, and the endoporus of feeding pipe 2 is hand-hole; Discharge nozzle 3 is provided with bottom described handpiece case 1, the endoporus of discharge nozzle 3 is for portalling, above-mentioned design is more considered to give bar larger parcel degree of support, thus makes longer bar can keep vertical in course of conveying, the conveying obstacle that minimizing bar bends and brings.
As shown in the figure, handpiece case 1 is fixed with drive motors 4, the power output shaft of described drive motors 4 is fixed with driven wheel 5, it is outside that drive motors 4 is positioned at handpiece case 1, and power output shaft stretches in handpiece case 1 through handpiece case 1 wall, described handpiece case 1 is provided with the top-pressure mechanism of swing arm 6 and top pressure swing arm 6, this swing arm 6 is rotationally connected with handpiece case 1, and one end of this swing arm 6 is provided with rotating pinch roller 7, by the pressure swing arm 6 of top-pressure mechanism top, the gear teeth of extruded bar stock and driven wheel 5 tightly touch described pinch roller 7, pinch roller 7 is U-shaped bearing or V-arrangement bearing preferably, bar can snap in the groove of U-shaped bearing or V-arrangement bearing, prevent bar partially squeezed.
In the present embodiment, top-pressure mechanism concrete structure is, comprise screw rod (not shown) and be arranged at the screw 8 on handpiece case 1, described swing arm 6 is pressed by the top of screw rod, and said structure is simple, easily processing, with low cost.On screw rod, cover has Compress Spring (not shown), one end of Compress Spring contacts with swing arm 6 and the nut of another side and screw rod is conflicted, because the diameter of the bar of outsourcing is uneven, thus, if the elastic force not in conjunction with Compress Spring pushes up pressure bar material, in the part that the diameter of bar is less, screw rod may push up pressure less than or pressure on top surface not enough, thus said structure design can ensure that the diameter change of bar can not produce bad impact to the conveying of bar.
Above to the printhead of a kind of 3D printer that the utility model embodiment provides, be described in detail, apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
