Background
At present FDM type 3D printer is more and more extensive in various occasions application, because the shaping part size needs, 3D printer volume is bigger and bigger, and corresponding printing speed is also faster and faster, and this requires printer shower nozzle module, can melt and extrude more volumetric wire rods in unit interval. Conventional showerhead modules typically include a nozzle, a rod-shaped heating tube, a heating block, a thermistor, and a throat. The rod-shaped heating pipe is inserted into the heating block to generate heat, the wire channel is arranged beside the heating pipe side by side, the nozzle and the throat are respectively communicated with two ends of the wire channel, and the thermistor is arranged on the heating block to detect the printing temperature. In the prior art, a nozzle module is usually provided with a heating pipe, the heating pipe is in a straight pipe shape, but the heating power of a single heating pipe is low, so that more wires cannot be melted in a short time, and the improvement of the printing speed is limited.
In order to improve the heating power, some printers improve the heating power by installing a heating pipe with a longer size and a higher power, but the heating block and an internal wire channel are required to be lengthened, so that the wire is in a melting state too early, the extrusion resistance is increased during printing, and the fault of a plug is easy to occur. Meanwhile, as excessive consumable materials in a molten state are reserved in the channel, the wire rod cannot be fully drawn back, the printing wire drawing phenomenon is more serious, and the printing quality is influenced. The other printers adopt a method of installing a plurality of heating pipes, but the structure of the spray head is overstaffed, the electric circuit is complex, and the difficulty of installation and maintenance is increased.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the main technical problem who solves provides a spiral heating shower nozzle and based on 3D printer of this shower nozzle, has advantages such as reliable performance height, compact structure, heating efficiency height, has extensive market prospect in 3D prints rapid prototyping's application and popularizing simultaneously.
In order to solve the technical problem, the utility model discloses a technical scheme be:
