Such as: [title] a kind of anti-leakage anti-block plug nozzle component for 3D printer, [patent No.] CN201420480656.3, [applying date] 2014.08.25, disclose a kind of anti-leakage anti-block plug nozzle component for 3D printer.Be made up of shower nozzle, shower nozzle bushing pipe, charging trunnion, trunnion bushing pipe and heater: the endoporus of described shower nozzle is for supporting shower nozzle bushing pipe and locating charging trunnion, and the bottom of shower nozzle screw thread is provided with leak preventing step; The bottom of described charging trunnion peripheral hardware screw thread is provided with the chamfering coordinating shower nozzle, inside establishes the stepped hole for positioning nozzle bushing pipe; Described heater is provided with the screwed hole for connecting shower nozzle and charging trunnion, is provided with the stepped hole for coordinating shower nozzle below screwed hole.Described shower nozzle bushing pipe and trunnion bushing pipe all adopt exotic material.This anti-leakage anti-block plug nozzle component not only can prevent silk material from blocking shower nozzle but also can prevent the silk stream melted from going out.
Above-mentioned utility model all have employed identical technological means, namely prevents shower nozzle from blocking with the passage that lubricity is good; This technological means can play certain anti-clogging effect really, but when the silk material of unfused silk material and fusing be bonded in charging trunnion exit cause block up time, passage the anti-skidding effect that plays just become limited, the situation that shower nozzle still can not be avoided to block occurs.
Therefore still there is the problem of shower nozzle blocking in existing printer head assembly, requires further improvement.
Summary of the invention
There is the problem of shower nozzle blocking in the existing printer head assembly of the present invention, provides a kind of printer head assembly with vibrator, can play anti-leakage anti-block effect simultaneously.
The anti-blocking printer head assembly of oscillatory type of the present invention, comprises shower nozzle, charging trunnion, heater, thread mechanism; The charging aperture of described shower nozzle is communicated with the discharging opening of charging trunnion, and heater is arranged on the heat affected zone close contact of shower nozzle outside and shower nozzle; Described shower nozzle, charging trunnion are all fixedly connected with by thread mechanism with heater; The intermediate location of described shower nozzle and charging trunnion is provided with leakproof ladder, the thread mechanism being fixedly connected with shower nozzle and charging trunnion is arranged on shower nozzle upper chamber inwall, charging trunnion outer wall is provided with reverse thread mechanism accordingly, and the screw thread of this thread mechanism extends to beyond shower nozzle charging aperture; Also comprise be arranged on charging trunnion outer wall by cause feed throat tube wall resonate and force the vibrator that silk material is separated with tube wall.
Further illustrate as of the present invention, described shower nozzle is provided with fixing collar at the outer wall corresponding with material trunnion thread mechanism position, and this fixing collar is made up of the material that thermal conductivity is poor.
Further illustrate as of the present invention, the thread mechanism of described charging trunnion also comprises reverse nut, and this thread mechanism that described reverse nut is arranged on extends on the screw thread beyond shower nozzle charging aperture, prevents the thread mechanism of charging trunnion from loosening by reverse extrusion.
Further illustrate as of the present invention, the vibration frequency range of described vibrator comprises the intrinsic frequency of feed throat tube wall.
Further illustrate as of the present invention, the inner chamber radius of described shower nozzle is greater than the inner chamber radius of charging trunnion.
Further illustrate as of the present invention, described shower nozzle and charging trunnion are respectively arranged with leakproof ladder accordingly, and precession thread mechanism between the two can make two leakproof ladder close contacts.
As preferred version of the present invention, described feed throat tube cavity arranges polytetrafluoroethylene (PTFE) passage.
The anti-blocking printer head assembly of oscillatory type of the present invention solves the shortcoming and defect of prior art, compared with prior art has following progress:
1, vibrator is added at charging trunnion outer wall, when the silk material of unfused silk material and fusing is bonded in charging trunnion exit, cause when blocking up, force silk material to be separated with tube wall by causing feed throat tube wall to resonate, silk material falls under gravity in the cavity of shower nozzle; The vibration frequency of vibrator is adjustable, the stopping state adjustment oscillation intensity of sight feed trunnion; When the intrinsic frequency of vibration frequency close to feed throat tube wall, the judder of trunnion wall can be caused, even the solid filament material being bonded in inwall also can not be gone out by " throwing " exceptionally.
2, shower nozzle and charging trunnion are respectively arranged with leakproof ladder accordingly, and precession thread mechanism between the two can make two leakproof ladder close contacts, and nozzle cavity is strictly closed; Therefore, even if do not use sealing ring also can prevent silk material molten mass from flowing out from shower nozzle side.
3, to stretch into shower nozzle chamber inner for charging trunnion, and compared to existing technology, to stretch into the structure of charging trunnion inside more reasonable for shower nozzle.Make because shower nozzle is copper material, thermal conductivity is good, and charging trunnion is made up of stainless steel, poor thermal conductivity; In existing structure, heat conducts from shower nozzle upper end to the silk material charging trunnion, and silk material does not enter shower nozzle chamber and just heated, and very easily causes silk material to soften too early; Silk material of the present invention enters shower nozzle chamber and is just heated, and prevents this problem to occur.
4, shower nozzle outside is provided with fixing collar, overcomes the shortcoming of shower nozzle copper material instability, prevents the deformation of shower nozzle thread mechanism, makes it more durable.
