Abstract
The utility model discloses a novel extruder, which comprises an acrylic support, a stepping motor, a driving gear, an extruding head, a filtering threaded pipe and a teflon pipe, wherein the stepping motor is fixed on the acrylic support, a connecting device of the driving gear is arranged at one end of the stepping motor, one end of the teflon pipe is connected with the filtering threaded pipe, the other end of the teflon pipe is connected with the acrylic support, an original filtering stainless steel pipe is replaced with the filtering threaded pipe, the teflon pipe is added behind the filtering threaded pipe, the threaded pipe accelerates heat dissipation, the heat conducted onto the threaded pipe is dissipated quickly, the temperature at a position of the acrylic support is reduced, besides, the teflon pipe is heat-resistant and heat-insulating, so that the acrylic support is protected, thermal deformation is avoided, the extruder is simple in structure and capable of operating for a long time and being produced in a very low cost, and the service life is prolonged.
Description
Technical field
The utility model relates to fusion 3d printer field, is specifically related to a kind of novel extruder.
Background technology
At present; The screen pipe of existing extruder parts is mostly for filtering stainless steel tube; Its shortcoming is to filter stainless steel tube can cause the acrylic deformation of timbering, so heat block can not work long hours to the heat acrylic support that leads; Filtering stainless steel tube can not go out the heat quick heat radiating, influences service life.
The utility model content
The utility model will address the above problem provides a kind of novel extruder; The transition stainless steel tube changes the transition screwed pipe into; And increase teflon pipe in the back, and screwed pipe has been accelerated radiating rate, and the heat that conduction is got on distributes very soon; Reduced the temperature at acrylic support place, teflon pipe is heat-resisting and adiabatic.
For addressing the above problem; The utility model is realized through following scheme: a kind of novel extruder, and this extruder comprises acrylic support, stepper motor, driven wheel, extruder head, said stepper motor is fixed on the acrylic support; Said driven wheel jockey is at stepper motor one end; Said extruder also comprises filtration screwed pipe and teflon pipe, and said teflon pipe one end connects the filtration screwed pipe, and the other end is connected to the acrylic support.
Said filtration screwed pipe all is connected heat block with extruder head, and said heat block is arranged on junction and the parcel that filters screwed pipe and extruder head.
The utility model changes the transition stainless steel tube into the transition screwed pipe, and increases teflon pipe in the back, and screwed pipe has been accelerated radiating rate, and the heat that conduction is got on distributes very soon; Reduced the temperature at acrylic support place, in addition, teflon pipe is heat-resisting and adiabatic; Protected the acrylic support like this, can not produce thermal deformation, it is simple in structure; Can work long hours, increase the service life, very less cost can be processed.
Below be to combine the specific embodiment and description of drawings that the utility model is done further description:
Description of drawings
Fig. 1 is existing extruder structure cutaway view;
Fig. 2 is the utility model structure cutaway view.
Among the figure: 1, stepper motor, 2, extruder head, 3, driven wheel, 4, the acrylic support, 5, ABS or PLA wire rod, 6, filter screwed pipe, 7, heat block, 8, teflon pipe, 9, filter stainless steel tube.
The specific embodiment
As shown in Figure 2; A kind of novel extruder, this extruder comprise acrylic support 4, stepper motor 1, driven wheel 3, extruder head 2, and stepper motor 1 is fixed on the acrylic support 4; Driven wheel 3 jockeys are at stepper motor 1 one ends; Extruder also comprises filtration screwed pipe 6 and teflon pipe 8, and teflon pipe 8 one ends connect filtration screwed pipe 6, and the other end is connected to acrylic support 4; Filter screwed pipe 6 and all be connected heat block 7 with extruder head 2, said heat block 7 is arranged on junction and the parcel that filters screwed pipe 6 and extruder head 2.
Deliver to the thermal treatment zone to ABS or PLA wire rod 5 through driven wheel 3, heat block 7 melts ABS or PLA wire rod 5 and under the promotion of driven wheel 3, in the aperture of front end extruder head 2, extrudes the filament of diameter 0.1-0.3mm.
As shown in Figure 1; Existing extruder comprises ABS or PLA wire rod 5, acrylic support 4, stepper motor 1, driven wheel 3, extruder head 2, filters stainless steel tube 9, filters stainless steel tube 9 and is directly connected to acrylic support 4, and its shortcoming is: transition stainless steel tube 9 can be heat guiding acrylic support 4; Cause 4 distortion of acrylic support; Therefore heat block 7 can not work long hours, and originally the requirement of stainless steel transition conduit 9 processing technologys is very high, is difficult for processing.
