Utility model content:
In order to solve the problem, it is simple that the utility model provides a kind of structure, and can realize 3D printer nozzle pass blocking, effectively prevent silk material, particles plug shower nozzle, anti-blocking performance is good, avoids the technical scheme occurring disconnected phenomenon of spraying or do not spray:
A kind of block-resistant type 3D printer nozzle structure, mainly comprise shower nozzle, nozzle, charging trunnion, heater, charging runner, silk stream road, the charging aperture of shower nozzle is communicated with the discharging opening of charging trunnion, heater is arranged on the heat affected zone close contact of shower nozzle outside and shower nozzle, shower nozzle, charging trunnion are all fixedly connected with by screw thread with heater, silk stream road is arranged on upper end of nozzle, the both sides in silk stream road are all connected with charging runner, be provided with filter course in charging runner, between charging runner, be also provided with anti-blocking passage.
As preferably, charging runner mainly comprises front incoming flow road and rear feeding runner, and front incoming flow road is connected with rear feeding runner, rear feeding runner connecting filament stream road, and front incoming flow road and rear feeding runner junction are provided with filter course.
As preferably, silk stream arranges anti-blocking passage above road, and silk stream arranges the second magnet below road, anti-blocking passage mainly comprises spring and the first magnet, spring connects the first magnet, and spring one end connects left side rear feeding passage, and first magnet one end connects right side rear feeding passage.
As preferably, rear feeding runner is also connected with reserved silk stream road, and reserved silk stream road is arranged on nozzle both sides, and the reserved silk stream road other end connects nozzle discharge hole, reserved silk stream road is provided with magnetic valve, and solenoid control reserves an open and close in stream road.
The beneficial effects of the utility model are:
(1) the utility model structure is simple, charging runner is divided into front incoming flow road and rear feeding runner, and arranges filter course in front incoming flow road and rear feeding runner junction, can to filter out in silk material the impurity such as particle, avoid blocking shower nozzle.
(2) the utility model also increases by two blocks of magnet on basis before, can to attract each other and the effect repelled gets off to prevent fine solid particle particle etc. from entering silk material passage mutually at magnet, and a grinding abrasion nozzle can also be avoided, the service life of prolonging nozzle.
Accompanying drawing illustrates:
Fig. 1 is Integral connection structure figure of the present utility model;
Fig. 2 is partial enlarged drawing of the present utility model.
Detailed description of the invention:
For making goal of the invention of the present utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
As Fig. 1, shown in Fig. 2, a kind of block-resistant type 3D printer nozzle structure, mainly comprise shower nozzle 1, nozzle 2, charging trunnion 3, heater 4, charging runner 5, silk stream road 6, the charging aperture of shower nozzle 1 is communicated with the discharging opening of charging trunnion 3, heater 4 is arranged on the heat affected zone close contact of shower nozzle 1 outside and shower nozzle 1, shower nozzle 1, charging trunnion 3 is all fixedly connected with by screw thread with heater 4, silk stream road 6 is arranged on nozzle 2 upper end, the both sides in silk stream road 6 are all connected with charging runner 5, filter course 7 is provided with in charging runner 5, anti-blocking passage 8 is also provided with between charging runner 5, charging runner 5 mainly comprises front incoming flow road 51 and rear feeding runner 52, front incoming flow road 51 is connected with rear feeding runner 52, rear feeding runner 52 connecting filament stream road 6, front incoming flow road 51 and rear feeding runner 52 junction are provided with filter course 7.Filter course 7 has tiny aperture, as ground floor Anti-blocking structure, has iris action, the particle of large-size is filtered in charging runner 5, and because the caliber of charging runner 5 is comparatively large, the particle be filtered is not easy to result in blockage,
Silk arranges anti-blocking passage 8 above stream road 6, silk arranges the second magnet 9 below stream road 6, anti-blocking passage 8 mainly comprises spring 81 and the first magnet 82, and spring 81 connects the first magnet 82, and spring 81 one end connects left side rear feeding passage 52, first magnet 82 one end connects right side rear feeding passage 52, when not spraying silk material, in a state of nature, the first magnet 82 is relative with second magnet 9 same sex for the first magnet 82, mutual repulsion, the second magnet 9 blocks a stream road 6.Prevent particle from piling up in silk stream road 6, keep silk stream road 6 to clean; When nozzle spray silk material, pressure acts on the first magnet 82 by silk material, forces spring 81 to shrink, and the first magnet 82 moves, and the magnetic pole relative with the second magnet 9 changes, and the first magnet 82 and the second magnet 9 attract each other.Silk stream road 6 communicates with charging runner 5, starts to spray the operation of silk material.After the end of job of spray silk material, under the effect of spring 81 screen resilience, the first magnet 82 resets, and magnetic pole changes, and the second magnet 9 resets under the effect of repulsion, again blocks a stream road 6.First magnet 82, spring 81 and the second magnet 9 form second layer Anti-blocking structure, and second layer Anti-blocking structure, by blocking a method in stream road 6, not only can prevent particle from entering a stream road 6, and ensure that spray silk material process is smooth, spray silk material is respond well.And avoid dust granules wearing and tearing nozzle, the service life of prolonging nozzle.
In addition, rear feeding runner 52 is also connected with reserved silk stream road 9, and reserved silk stream road 9 is arranged on nozzle 2 both sides, and reserved silk stream road 9 other end connects nozzle 2 discharging opening, reserved silk stream road 9 is provided with magnetic valve 10, and magnetic valve 10 controls the open and close in reserved silk stream road 9.Reserved silk stream road 9 can, when silk stream road 6 blocks, as silk stream road for subsequent use, avoid the operation of spray silk material to interrupt.
The utility model structure is simple, charging runner is divided into front incoming flow road and rear feeding runner, and arranges filter course in front incoming flow road and rear feeding runner junction, can to filter out in silk material the impurity such as particle, avoid blocking shower nozzle; Also on basis before, increase by two blocks of magnet, can to attract each other and the effect repelled gets off to prevent fine solid particle particle etc. from entering silk material passage mutually at magnet, and a grinding abrasion nozzle can also be avoided, the service life of prolonging nozzle.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
