The signal from the pressure sensor is received, controls rotating and reverse for the 3rd gear.
Preferably, the first gear and the outer tooth footpath of the second gear are respectively less than the 3rd gear.
The directive wheel is connected with telescopic spring mechanism in side.
Conveying pipeline conveying that the first gear is acted on below first feed pipe, the second gear act on
Conveying pipeline conveying below two feed pipes is alternately.
In the use of the present invention, the first feed pipe and the second feed pipe are respectively charged into printed material, it is assumed that wherein first enters
Material feed tube first carries out print job, i.e. first gear and the 3rd working gear, and material is made jointly in directive wheel with first gear
Heater is entered by conveying pipeline with lower；Now the material of the second feed pipe is not worked temporarily due to second gear, therefore not
Into conveying pipeline, the pressure sensor that is equipped with directive wheel, when material fracture of wire occurs or exhausted in the first conveying pipeline, it is oriented to
Distance between wheel and the 3rd gear changes, and pressure sensor receives pressure change signal, feeds back to driving equipment, and driving is set
The 3rd gear of standby control is inverted, and now, second gear stops operating, and the 3rd gear starts, and the material of the second feed pipe is opened
Beginning enters conveying pipeline, realizes the seamless supply of material.
Compared with prior art, the above-mentioned technical proposal that the present invention uses, it is simple in construction, it is reasonable in design, realize and move certainly
Material, feed supplement process, solve fracture, the material that 3D printer occurs in the course of the work and the situation such as use up, make the seamless confession of material
Give, saved material, while time saving human-saving, alleviate the labor intensity of worker.
