Abstract
The utility model discloses a needle valve is let slip a remark 3D and is printed shower nozzle, including melt pipe, the intraductal needle valve sleeve of installing of melt, there is the runner between needle valve sleeve and melt inside pipe wall, slidable mounting has the thimble on the needle valve sleeve, the inside slide that is formed with the vertical direction of needle valve sleeve, the upper end slidable mounting of thimble is in the slide, and the lower extreme of thimble can block up the discharge gate of melt pipe, still installs the drive arrangement who connects the thimble on the melt pipe, and drive arrangement drive thimble moves along the slide up or down to make the thimble open or block up the discharge gate of melt pipe. It is simple that this 3D prints sprinkler structure, and washings that wholly can break realizes the switching of control discharge gate, and the ooze that the ooze and the print job that have prevented hot melt material when print job preheats finish the unnecessary hot melt material in back leads to the fact the product to pollute, does not just need to carry out frequent opening and close to heating device when continuity of operation, has guaranteed the life of equipment.
Description
Technical field
The utility model relates to 3D printer field, is specially a kind of needle-valve and lets slip a remark 3D printing head.
Background technology
3D printing technique is a kind of advanced manufacturing technology, and printing consumables can adopt multiple material, as metal dust and plastics etc.The technology of current employing plastics consumptive material common are fuse deposition technique, it is by thread heat-fusible materials heat fused, gush out by squeezing with the shower nozzle of a minute nozzle, after nozzle ejection, on the table, temperature, lower than starting solidification after solidification temperature, finally forms finished product by the accumulation layer by layer of material to deposition, shower nozzle is wherein exactly a core component, is also one of 3D printer technology comparing core.
But current 3D printing head generally adopts the input controlling thermo-fuse to control its ejection flow, because thermo-fuse needs could spray through being heated into molten condition, so very high requirement will be had to the efficiency of heating surface of heater, during initialization, the efficiency of heating surface needs rapidly thermo-fuse to be heated to molten condition, need after printing completes to cool down rapidly, prevent the ejection of unnecessary hot melt printed material, in print job frequently, very large infringement can be caused to heater, cause the defect that its service life is short.
Utility model content
In order to overcome the shortcoming that prior art is mentioned, the utility model provides a kind of structure simple, and accurate control material spray volume is 3D printing head and the needle-valve of long service life is let slip a remark.
The utility model solves the technical scheme that its technical problem adopts: a kind of needle-valve is let slip a remark 3D printing head, comprise the melt pipe with charging aperture and discharging opening, in described melt pipe, needle-valve sleeve is installed, runner is there is between described needle-valve sleeve and described melt inside pipe wall, described needle-valve sleeve is slidably fitted with thimble, described needle-valve sleeve inner is formed with the slideway of vertical direction, the upper end of described thimble is slidably mounted in described slideway, the lower end of described thimble can block the discharging opening of described melt pipe, described melt pipe is also provided with the drive unit connecting described thimble, described drive unit drives described thimble to face upward or downward along described slideway and moves, thus make described thimble open or block the discharging opening of described melt pipe.
The eccentric wheel that described drive unit comprises drive motors and driven by described drive motors, described eccentric wheel connects the upper end of described thimble, and along with described eccentric rotation, described thimble is close to described eccentric surface and is faced upward or downward motion.Described drive unit also can be cylinder or the hydraulic cylinder of movement in vertical direction, and the piston rod of described cylinder or hydraulic cylinder connects the upper end of described thimble and drives described thimble to face upward or downward motion.
The sidewall of described melt pipe is also provided with heater.
Described melt pipe comprises tempreature bulb and discharge nozzle, and described tempreature bulb and discharge nozzle are removably connected by gas thread, the runner of melt pipe convenient for cleaning.
Side in described tempreature bulb pipe is provided with installing plate, and described needle-valve sleeve is detachably installed on described installing plate by screw.
The beneficial effects of the utility model are: this 3D printing head structure is simple, overall detachable cleaning, thimble is driven to move up and down by drive unit, thus thimble is opened or blocks the discharging opening of melt pipe, realize the opening and closing controlling discharging opening, prevent when print job preheating hot melt material ooze and oozing of hot melt material unnecessary after print job causes contamination of products, and at the Shi Buxu that works continuously, heater to be opened and closed frequently, ensure that the service life of equipment.
