By fast for each part quick-detach, it is convenient to clean dredging printhead.
Described cap 4 is provided with the through hole connecting fiber trunnion 6 and resin trunnion 9, and fiber trunnion 6 and resin trunnion 9 are equal
It is detachably connected on the through hole of cap 4, the through hole connecting resin trunnion 9 is also removably connected with resin shower nozzle 8.For even
Connecing fiber trunnion 6 and the through hole of resin trunnion 9 can be screwed hole, thus realize threaded or with fiber trunnion 6
The corresponding cylindrical hole with resin trunnion 9 external diameter, thus realize interference fit connecting, two ways can be realized detachably connecting
Connect.Additionally, through hole be preferably formed with multiple, thus realize the identical material of multiply or different materials resins 12 to enter silk simultaneously.And
And through hole should be uniformly distributed around fiber trunnion 6, so that the resin all having all amounts in each orientation of fiber trunnion 6 enters
Enter, prevent fiber trunnion 6 surrounding resin from entering uneven, thus cannot ensure that the fiber 11 in fiber trunnion 6 just cannot be in
Middle position.When being wrapped in the resin of fiber 11 surrounding and being the most uniform, that is, when fiber 11 is in resin middle, the effect of printing
Fruit is best.Resin shower nozzle 8 first should be connected to cap 4 from the inside of cap 4, then again from the external connection of cap 4
Upper resin trunnion 9 simultaneously makes the lower end of resin trunnion 9 and the upper end of resin shower nozzle 8 be in close contact, and prevents resin from overflowing.If tree
The upper-end contact defective tightness of the lower end of fat trunnion 9 and resin shower nozzle 8, resin is possible to from resin trunnion 9, shower nozzle 8 and cap 4
Between gap in overflow.

5 can be threaded connection or the mode such as interference fit is detachably connected to the lower end of fiber trunnion 6.It is detachably connected use
Make fiber 11 block when preventing resin from entering in fiber trunnion 6 cannot clear up.Because the resin of melting is under the effect of the pressure
The overwhelming majority can flow out from spray outlet, but the pipeline still having sub-fraction along fiber 11 progresses into fiber trunnion
In 6.Fiber spray nozzle 5 can control, by controlling outlet caliber size, the amount that resin enters, and resin additionally can be guided to flow,
Thus preventing resin from entering in fiber trunnion 6.
The inside of described resin trunnion 9 is cased with Teflon pipe 10, and Teflon pipe 10, for heat-insulated, prevents heat transfer
Resin to resin trunnion 9 upper end is so that the resin of resin trunnion 9 upper end melts, thus easily blocking resin trunnion 9.
Form cavity 15 after described inner chamber 2 and cap 4 connection, cavity 15 is used for accommodating the resin melting, and so that melt
Resin under the effect of the pressure from bottom outlet extrusion.
The plurality of supersonic generator 16 is fixedly connected on the outer wall of heat-conducting block 3 or the inwall of inner chamber 2, around inner chamber
2 axis is uniformly distributed.Supersonic generator 16 can by the modes such as glue bonding or welding be fixedly connected on inner chamber 2 or
On heat-conducting block 3.If supersonic generator 16 is fixedly connected on inner chamber 2 inwall, block 4 needs be provided with and rethread the hole of line simultaneously
Carry out encapsulation process.Supersonic generator 16 can produce ultrasound wave, thus driving molten resin vibrations so that resin and fiber
Bond effect greatly promote.
