Abstract
The invention relates to a feeding mechanism with pinch rollers, belonging to the technical field of rapid formation. The mechanism comprises a driving wheel and a driven wheel moving in a vertical direction of an axial line, the two wheels are close to and axially parallel to each other, cutting edges are distributed on the circumference of the driving wheel, the driven wheel is fixed with an elastomer. The invention improves the wire conveyance from a friction force-driving way to a pressure-driving way, the cutting edges are cut into the wire so that the conveyance is stable and reliable, further, the velocity of the conveyance is mainly determined by the velocity of the driving wheel so that the conveyance can be faster and more stable.
Description
Technical field
The invention belongs to the RP technique field, particularly relate to the connecting gear of rapid forming system.
Background technology
The basic principle of rapid forming system is: connecting gear is sent into the silk material in the liquefier of shower nozzle fusing and melted material is extruded from the nozzle than minor diameter, form material and pile up the path, under the control of computer, realize fast shaping technology based on melt extruded stack shaping principle.Therefore effective work of connecting gear is the crucial first step of whole system normal operation.Existing connecting gear (see figure 1) is to be clipped a material 2 in wheel 1 rotation process and goed ahead and realize transmitting purpose by two sending to of rotating in opposite directions; for frictional force between wheel 1 and thread material 2 is sent in increase to; send on the wheel 1 for two annular knurl 3 is arranged; but because silk material surface is very smooth; and annular knurl is not wear-resisting yet; skid through regular meeting in transport process, the silk material is not in time sent to, causes the whole system cisco unity malfunction.
Summary of the invention
At the defective in the above-mentioned field, the invention provides a kind of feed mechanism with pinch roller, can not cause the phenomenon of skidding between feed mechanism and the silk material, realize effectively transmitting.
The feed mechanism of band pinch roller is characterized in that: comprise close mutually and a parallel driving wheel and the driven pulley that moves along the axis normal direction of axis, the wheel of described driving wheel is distributed with cutting edge on week, is fixed with an elastomer on the described driven pulley.
Described axis normal direction is a horizontal direction.
Described driven pulley is a bearing.
Described elastomer be fixed in bearing away from the moving runner side.
Described elastomer is a spring.
Described cutting edge evenly distributed on wheel week.
Described cutting edge thickness is 0.05-0.5mm, highly is 0.05-1mm.
The present invention makes two runners of doing relative motion into a driving wheel and a driven pulley, the silk material is positioned in the middle of the two-wheeled, driving wheel rotates, driven pulley under elastomeric pressure near driving wheel, cutting edge on the driving wheel is cut in the material under the effect of this pressure, and move down by rotating band movable wire material, because the silk material is to be cut also and then to leave cutting edge slightly by cutting edge, therefore moving downward of silk material is not to rely on frictional force to move but the cutting edge drive, so situation that can not occur skidding, make the transmission of a material more stable, continual and steady the sending to of the moving realization silk material of not stall of driving wheel, transfer rate also can be regulated and control by the rotating speed of driving wheel.Because the penetraction depth of cutting edge is 0.05-1mm, it can not cut the silk material or cut off, and cutting edge is that the metal material of the identical material of employing driving wheel mills pin and forms, and is wear-resisting, longer service life.
The axis normal direction can need be all directions according to what transmit material, if a silk material is wanted the vertical direction transmission, then the axis normal direction is a horizontal direction.If the silk material is wanted horizontal transmission, then the axis normal direction of two-wheeled is for being vertical direction.
Driven pulley can rotate and get final product, preferred bearing.Elastomericly suppress distortion and all can produce pressure or pulling force, consider spatial distribution connected object, preferably elastomer is fixed in bearing away from the moving runner side.
If elastic body active gives driven pulley with pressure, so the simple spring of preferred structure.
The present invention transmits a material to existing main frictionally and is improved to main depended on pressure and transmits, and in the cutting edge incision silk material, makes and transmits reliable and stablely, and the speed that transmits mainly decides by the speed of driving wheel, and is so transfer rate can be faster, more steady.

The specific embodiment
See shown in Figure 2, the feed mechanism of band pinch roller, comprise a close driving wheel 4 and driven pulley mutually, the wheel of described driving wheel 4 is distributed with cutting edge 7 on week, be fixed with an elastomer on the described driven pulley, driven pulley can move along with elastomeric suppressing along the axis normal direction of driven wheel, and Biao Shu axis normal direction is a horizontal direction in the drawings.Driving wheel 4 rotates, near driving wheel 4, the cutting edge 7 on the driving wheel 4 is cut under the effect of this pressure in the material 2 driven pulley, not the situation that can occur skidding under elastomeric pressure, make the transmission of a material 2 more stable, transfer rate also can be regulated and control by the rotating speed of driving wheel 4.Because the penetraction depth of cutting edge 7 is 0.05-1mm, it can not cut the silk material or cut off, and cutting edge is that the metal material of employing driving wheel 4 identical materials mills pin and forms, and is wear-resisting, longer service life.
Driven pulley can rotate and get final product, preferred bearing 5.Elastomericly suppress distortion and all can produce pressure or pulling force, consider spatial distribution connected object, preferably elastomer is fixed in bearing 5 away from driving wheel 4 sides.
If elastic body active gives driven pulley with pressure, so the simple spring 6 of preferred structure.
The present invention transmits a material to existing main frictionally and is improved to and main transmits for the pressure of bearing 5 by spring 6, make in the cutting edge 7 incision silk materials 2 on the driving wheel 4, make transmission reliable and stable non-slip, the moving transmission that realizes silk material 2 of driving wheel 4 not stalls, and the speed that transmits is mainly decided by the speed of driving wheel, so transfer rate can be faster, and is more steady.
