Description
Technical field
This utility model relates to a kind of abrasive band feeding mechanism.
Background technology
Crankshaft journal polishing at present uses abrasive band polishing, and belt sander is designed with scarce on abrasive band feeding controls
Falling into, hand feed, operating difficulties are leaned in the feeding of belt sander, and the amount of feeding is unstable, wastes bigger.
The patent of invention of Publication No. CN103158065A discloses a kind of abrasive band automatic feed mechanism, and it includes
Feeding cylinder, feed rack, take-up case, and be positioned at the spool gear of take-up case box body, two short gears,
Feeding sector gear, fixing axle and feed shaft, described fixing axle is provided with unidirectional needle bearing II through two ends
Spool gear be fixed on take-up case front end；Described feed shaft sequentially passes through and is provided with the short of unidirectional needle bearing I
Gear, the feeding sector gear of unidirectional needle bearing III is installed and another is provided with unidirectional needle bearing I
Short gear be arranged on the middle part of take-up case, said two short gear is meshed with spool gear simultaneously, feed shaft
Two ends be installed in the monosymmetric installing hole of take-up case；Described feeding cylinder is fixed on the rear end of take-up case
Outside, described feed rack is loaded on feeding cylinder front end, and feed rack is positioned at take-up case top and fans with feeding
Shape gear is meshed, and the piston movement of feeding cylinder drives feed rack to move forward and backward.
Above-mentioned abrasive band automatic feed mechanism uses the engagement of two gears to realize the auto-feed in abrasive band, but,
When two gear engagements, abrasive band can be made to produce flexural deformation, this mechanism is for being internally provided with enhancing
For the abrasive band of structure sheaf, it is not easy to make abrasive band be returned to original shape, and the layer in existing abrasive band
And mostly use glue bonding between layer, after oppressing through the engagement of gear, be easily caused bonding part cracking,
Thus abrasive band is damaged.
Summary of the invention
For above-mentioned technical problem, this utility model provide a kind of will not make during transmitting abrasive band deformation and
The abrasive band feeding mechanism destroyed.
Realize the technical solution of the utility model as follows:
Abrasive band feeding mechanism, including take-up case and motor, also include the first friction roller, the second friction roller with
And drivewheel and driven pulley, the two ends of described first friction roller are bearing on take-up case by clutch shaft bearing, and
One end of one friction roller is provided with axial extension, and this extension reaches the outside of take-up case, described driven
Wheel is fixed on the extension of the first friction roller, and the second friction roller is arranged on take-up case by the second bearing,
Described motor is fixed on take-up case, motor output end axially and the first friction roller axially in parallel, described
Drivewheel is fixed on the outfan of motor, and drivewheel is in transmission connection with driven pulley or coordinates.
The extension of described first friction roller is provided with axle sleeve, one end of this axle sleeve and the axial end of driven pulley
Supporting, the other end of axle sleeve is supported with the box wall of take-up case.
Another axial end of described driven pulley is spacing by the nut being fixed on extension.
Have employed such scheme, during utility model works, the power exported by motor drives drivewheel to turn
Dynamic, power is transferred to driven pulley by drivewheel, thus drives first friction roller to rotate, first friction roller
Impart power to the second friction roller by friction force, drive the second friction roller to rotate, thus realize sand
Band is sent into.Due to two friction rollers and abrasive band gross area contact, abrasive band, in being transmitted through kind, will not produce
Bending bending, thus it is ensured that abrasive band is intact.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Detailed description of the invention
With specific embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
See Fig. 1, abrasive band of the present utility model feeding mechanism, including take-up case 1 and motor 2, also include
First friction roller the 3, second friction roller 4 and drivewheel 5 and driven pulley 6, the two of described first friction roller 3
End is bearing on take-up case 1 by clutch shaft bearing, and one end of the first friction roller 1 is provided with axial extension 3a,
This extension 3a reaches the outside of take-up case, and the two ends of the first friction roller are equipped with axle, wherein the axle of one end
Short, the axial length of the other end, a part for major axis is used for assembling with clutch shaft bearing, another part of major axis
Define extension 3a.Described driven pulley 6 is fixed on the extension 3a of the first friction roller 3, driven pulley
6 is circumferentially fixed with extension 3a by spline, in order to limit the axial displacement of driven pulley 6, and described first friction
The extension 3a of roller is provided with axle sleeve 7, and the axial end of one end of this axle sleeve 7 and driven pulley 6 is supported, axle
The other end of set is supported with the box wall 1 of take-up case, and another axial end of described driven pulley 6 prolongs by being fixed on
Nut in extending portion is spacing.Second friction roller 4 is arranged on take-up case by the second bearing, the first friction roller 3
With the roll body of the second friction roller 4 all in the inside of take-up case 1, the first friction roller 3 and the second friction roller 4 lead to
Cross friction force and carry out transmission.Described motor 2 is fixed on take-up case 1, motor 2 outfan axial
Axially in parallel with the first friction roller 3, described drivewheel 5 is fixed on the outfan of motor, drivewheel 5
It is in transmission connection with driven pulley 6 or coordinates.Drivewheel 5 and driven pulley 6 preferentially use friction roller, between the two
By friction force transmission, the volume and weight of drivewheel 5 is all much smaller than driven pulley 6, it is preferable that
The weight of drivewheel 5 is 1st/10th of driven pulley 6, thus after motor quits work, by friction
Active force so that the inertia of drivewheel cannot drive driven pulley, and driven pulley can also stop in time,
So be conducive to improving the precision of transmission sand paper.Drivewheel 5 and driven pulley 6 transmission can also use gear,
The type of belt drive such as sprocket wheel.
