Abstract
The utility model belongs to 3D prints the field, is a self -adaptation 3D printer thread feeding mechanism, including fixing base and setting silk pressing arm and action wheel on the fixing base be provided with in the silk pressing arm one from the driving wheel, the action wheel with send a thread passageway from forming between the driving wheel, the silk pressing arm has first link and second link, first link with holder hinged, the second link is used for the adjustment through one driven crop rotation is used in the elastic adjustment device and the fixing base of action wheel upward pressure are connected. Compared with the prior art, the utility model discloses to install from the silk pressing arm one end and the holder hinged of driving wheel, the other end passes through the elastic adjustment device and connects to it is used in the transport that pressure on the action wheel is used for the consumptive material to adjust trailing wheel action through the silk pressing arm. Because thread feeding mechanism is the frictional force drive consumptive material motion by the action wheel that has the damping layer, no matter is to flexible consumptive material consequently, or the stereoplasm consumptive material, can all reach a good effect of sending.
Description
Technical field
The utility model belongs to 3D and prints field, specifically a kind of adaptive 3 D printer wire feeder.
Background technology
3D printer common on the market, can only print for the consumptive material of a certain class, can only print hard consumptive material or can only print flexible consumptive material, wants to print soft or hard 2 kinds of consumptive materials, must change the wire feeder of printer, bother very much.And the wire feeding gear commonly used on the market, be roller gear, utilize the occlusion of gear, consumptive material is sent into printer, when wire feed is obstructed, consumptive material stop motion, but gear is still ceaselessly being engaged consumptive material, cause consumptive material impaired, even occur the phenomenon biting consumptive material broken.
Summary of the invention
The purpose of this utility model is to solve above-mentioned 3D printer wire feeder Problems existing, provides a kind of and can print wire feeder that is flexible and hard consumptive material simultaneously.
A kind of adaptive 3 D printer wire feeder, comprise holder and be arranged on holder upper compression filament arm and driving wheel, a driven pulley is provided with in described silk pressing arm, wire feed passage is formed between driving wheel and described driven pulley, it is characterized in that: described silk pressing arm has the first link and the second link, described first link and described holder hinged, described second link is connected with holder by one to act on pressure on described driving wheel flexible adjustment device for adjusting described driven pulley.
Described flexible adjustment device is spring, and described holder is provided with holder lead, and described silk pressing arm is provided with silk pressing arm lead, and described both ends of the spring is enclosed within described holder lead and silk pressing arm lead respectively.
The outer surface of described driving wheel is damping layer.
Described damping layer is rubber layer.
The outer peripheral face of described driven pulley is provided with wire feeding trough.
The cross section of described wire feeding trough is V-type.
Motor is connected with in the rear end of described driving wheel.
Compared with prior art, the beneficial effect that the utility model has is:
The utility model is by hinged for the silk pressing arm one end and holder being provided with driven pulley, the other end is connected by flexible adjustment device, thus adjust trailing wheel action by silk pressing arm and be used in the conveying of the pressure on driving wheel for consumptive material, this structure does not need driving wheel and driven pulley to adopt the mode of gears meshing, only consumptive material need not skidded on driving wheel by compression and namely complete the conveying of consumptive material.Due to the frictional force drive consumptive material motion that wire feeder is the driving wheel by having damping layer, no matter be therefore for flexible consumptive material, or hard consumptive material, good wire feed effect can be reached.
Because wire feeder relies on the frictional force of rubber to provide power for consumptive material, when consumptive material is subject to larger resistance, consumptive material skids on driving wheel, and therefore can not wear and tear consumptive material.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model adaptive 3 D printer wire feeder, comprise holder 3, the motor 1 be fixed on holder 3, the silk pressing arm 4 being connected to the driving wheel 2 on motor 1 and being connected to by rotating shaft 7 on holder, a driven pulley 5 is had by pinned connection in silk pressing arm 4, wire feed passage is formed between driving wheel 2 and driven pulley 5, be connected with the flexible adjustment device acting on pressure on driving wheel 2 for adjusting driven pulley 5 between the other end of silk pressing arm 4 and holder 3, wherein flexible adjustment device adopts spring 6.Spring 6 two ends are enclosed within the holder lead of holder and the silk pressing arm lead of silk pressing arm respectively.
The outer surface of the driving wheel 2 of the utility model wire feeder is damping layer, and damping layer is rubber layer, also can adopt the glue coating wheel of cladding rubber layer.The outer peripheral face of driven pulley is provided with wire feeding trough, and the cross section of wire feeding trough is V-type or other shapes.
The operation principle of the utility model wire feeder is: driving wheel rotates under motor 1 drives, silk pressing arm 4 under the action of the spring, for driven pulley provides certain pressure, make it compress driving wheel, consumptive material passes through from the gap of driven pulley and driving wheel, the great abrasive rubber of one deck frictional force due to driving wheel outer layer covers, therefore, consumptive material under the drive of driving wheel, can enter printer, realizes printing function.
