Abstract
The utility model discloses an extrusion device of a 3D (three-dimensional) printer. The extrusion device comprises a heating unit, a feeding pipe and an extrusion nozzle, wherein the feeding pipe and the extrusion nozzle are arranged on and connected to the heating unit, and the feeding pipe is communicated with the extrusion nozzle. The extrusion device is characterized by also comprising a polytetrafluoroethylene pipe which is in sleeve connection inside the feeding pipe and is communicated with the extrusion nozzle. The extrusion device has the advantages that the polytetrafluoroethylene pipe is in sleeve connection inside the feeding pipe, and as polytetrafluoroethylene can resist high temperature, is extremely low in frictional coefficients and can play a role of lubrication, a raw material passes through the polytetrafluoroethylene pipe, then is heated by the heating unit, and finally is extruded by the extrusion nozzle and printed, so that the raw material is smoothly extruded in the whole extrusion process; when the extrusion device is not used, the raw material does not remain in the polytetrafluoroethylene pipe; therefore, the extrusion device is convenient to use and cost-saving.
Description
Technical field
The utility model relates to a kind of extrusion device of 3D printer.
Background technology
Existing 3D printer, its extrusion device mainly comprises a heating unit, a feed pipe and a nozzle, on heating unit, offer a through hole, feed pipe and nozzle are installed in respectively on this through hole lower end and are connected, and raw material enters feed pipe and from nozzle, extrudes and print after heating unit is heated.By feed pipe, adopt common stainless steel tube, when extrusion device is stopped using, remaining raw material easily cements in feed pipe, carry out when secondary is used after the residual raw materials removing in feed pipe, could using, use extremely inconvenience, and waste raw material, cause cost to raise.
Utility model content
The utility model provides a kind of extrusion device of 3D printer, and it has overcome the existing deficiency of background technology.The technical scheme adopting that the utility model solves its technical problem is: a kind of extrusion device of 3D printer, it comprises a heating unit (100), a feed pipe (200) and nozzle (300), feed pipe (200) and nozzle (300) are all installed in heating unit (100) and feed pipe (200) and nozzle (300) and are connected, it is characterized in that: it also comprises polyfluortetraethylene pipe (400), this polyfluortetraethylene pipe (400) is socketed in feed pipe (200) and is connected with nozzle (300).
Among one preferred embodiment: described heating unit (100) is provided with the female screw of a tool (110), feed pipe (200) is provided with external screw thread, nozzle (300) is provided with external screw thread, feed pipe (200) is screwed onto heating unit (100) by the cooperation of internal and external threads, and nozzle (300) is screwed onto heating unit (100) by the cooperation of internal and external threads.
Among one preferred embodiment: described polyfluortetraethylene pipe (400) is provided with the first pin-and-hole, described feed pipe (200) is provided with the second pin-and-hole, separately be provided with pin, described pin is fixed together polyfluortetraethylene pipe (400) and feed pipe (200) through the second pin-and-hole and the first pin-and-hole.
Among one preferred embodiment: described feed pipe (200) adopts stainless steel.
Among one preferred embodiment: described heating unit (100) is one to be built-in with the heat block of heating tube.
The technical program is compared with background technology, and its tool has the following advantages:
1. in feed pipe, be socketed polyfluortetraethylene pipe, because polytetrafluoroethylene (PTFE) can not only be high temperature resistant, and coefficient of friction is extremely low, can lubricate, make raw material after polyfluortetraethylene pipe, by heating unit, heat and extrude printing by nozzle, make raw material keep smooth and easy in whole extrusion, and when extrusion device is not used, raw material can not remain in polyfluortetraethylene pipe yet, makes not only easy to use, and cost-saving.
2. between feed pipe and heating unit and nozzle and heating unit, be threaded connection, simple in structure, cost is low.
3. between polyfluortetraethylene pipe and feed pipe, by pin, fix, prevent that polyfluortetraethylene pipe from rocking in feed pipe, effect is extruded in impact.
Accompanying drawing explanation
