Description
Technical field
The utility model is related to a kind of display screen structure more particularly to a kind of 3D printer extruders.
Background technology
The conveying of general 3D printer printed material is required for using extruder, the direct shadow of quality of extruder structure design
Ring convenience and efficiency to charging.
In existing 3D printer structure, for extruder there are mainly two types of type, one kind is that distal end is fed, and is squeezed out in such form
Machine and printing head are separately to be fixed on two different positions, and the wire rod 3 that extruder transports out is defeated by teflon pipe 7
It send to printing head, below figure 1；Another is that near-end is fed, and extruder 10 and printing head 9 are fixed in such form
It a position, moves together, the wire rod 3 that extruder 10 transports out is directly entered and beats under the driving of charging motor 11
Print nozzle 9, wherein 8 be radiating module, below figure 2.
The mode extruder charging of Fig. 1 is cumbersome, first applied force to adjust extruder regulating system at regulation handle 5
4, it unclamps wire rod 3 and it can be moved freely, while 3 applied force of wire rod is sent into the left in teflon pipe 7.Since wire rod finished product is
Weblike material initially has bending, and straightness is not good enough, and wire rod 3 often occurs in charging process cannot enter teflon pipe 7,
An other people is needed to assist to clamp 3 end of wire rod with tweezers and be sent in teflon pipe 7 at this time.
The mode extruder charging of Fig. 2 is also cumbersome, with Fig. 1 processes.
Existing extruder structure form has the disadvantage that：
The regulation handle of Fig. 1 uses laborious；
The adjusting of Fig. 1 tensile forces must use instrument；
The structure type charging trouble of Fig. 1 and Fig. 2；
The structure type of Fig. 1 and Fig. 2 needs others to assist.
Utility model content
To solve the problems of the prior art, the utility model provides a kind of 3D printer extruder.
The utility model includes feed system and the regulating system for adjusting feed system feeding, wherein, feed system
Motor gear including feeding idle pulley, drive feeding idle pulley feeding, connector and teflon pipe；The feed system includes first-hand
Handle and second handle, first handle are connected with connector, and the first handle is equipped in joint enters teflon pipe convenient for wire rod
Pilot hole, the pilot hole connects with teflon pipe.
The utility model is further improved, the pilot hole be horn-like, aperture and macropore including being arranged on both ends,
The aperture is set close to connector.
The utility model is further improved, and the regulating system further includes spring, adjusting bolt, wherein, the adjusting
First handle and second handle are bolted, and the distance of first handle and second handle can be adjusted, the spring is socketed in
In adjusting bolt, and it is arranged between first handle and second handle.
The utility model is further improved, and the adjusting bolt includes bolt and wing nut.
Compared with prior art, the beneficial effects of the utility model are：It is either manual or semi-automatic, such structure dress
Expect it is very convenient, without other people assist；Tensile force is adjusted without instrument；It, can be convenient and efficient using wing nut using laborsaving
Feed system is adjusted.
Description of the drawings
Fig. 1 and Fig. 2 is prior art construction schematic diagram；
Fig. 3 is the utility model structure diagram.
Specific embodiment
The utility model is described in further details with reference to the accompanying drawings and examples.
As shown in figure 3, the utility model includes feed system and the regulating system for adjusting feed system feeding,
In, feed system includes feeding idle pulley 1, the motor gear 2 for driving 1 feeding of feeding idle pulley, connector 6 and teflon pipe 7；It is described to send
Material system includes first handle 5 and second handle 14, and teflon pipe 7 is connected by connector 6 with first handle 5, described first-hand
Handle 5 is equipped with the pilot hole 12 convenient for wire rod 3 into teflon pipe 7 at connector 6, and the pilot hole 12 is connected with teflon pipe 7.
By the setting of pilot hole 12, so that feeding is very convenient, other people is not required to assist.
Preferably, the pilot hole 12 is horn-like, aperture and macropore including being arranged on both ends, and the aperture leans on proximity
First 6 are set, and horn-like bullport are especially added on extruder first handle 5, being not in that 3 device to hole of wire rod is uneven can not push away
Situation about entering.
This example regulating system further includes spring 13, adjusting bolt, wherein, adjusting bolt connection first handle 5 and the
Two handles 14, and the distance of first handle 5 and second handle 14 can be adjusted, the spring 13 is socketed in adjusting bolt, and
It is arranged between first handle 5 and second handle 14.
The adjusting bolt of this example includes bolt 16 and wing nut 15.It is easy to use and laborsaving using wing nut 15,
Tensile force is adjusted without instrument；Conveniently feed system can be adjusted.
This example charging process is as follows：Wing nut 15 is rotated first, between reducing between first handle 5 and second handle 14
Away from lifting the feeding idle pulley 1 on first handle 5, and increase feeding idle pulley 1 and 2 gap of motor gear allows wire rod 3 to pass through
Feeding idle pulley 1 and motor gear 2, manual feeding then keep 15 position of wing nut that wire rod 3 is pushed into teflon pipe 7；Motor
Auxiliary feeding then restores wing nut 15 to original position, feeding idle pulley 1 and motor gear 2 and clamps wire rod 3, starts motor by wire rod 3
It is pushed into teflon pipe 7.
The specific embodiment of the above is the better embodiment of the utility model, and it is new not to limit this practicality with this
The specific implementation scope of type, the scope of the utility model includes being not limited to present embodiment, all according to the utility model
The equivalence changes made are within the protection scope of the present utility model.
