Abstract
The utility model relates to a swing type lath cutter, which is characterized in that a pair of gear pairs, which are driven by a motor through a belt pulley, are arranged in a machine frame, one end of a draw bar is fixed on an eccentric wheel which is coaxial with the driven gears, the other end of the draw bar is connected with a reciprocating rack, a driven gear axle is rotated because that a cam of the driven gear axle of the is driven by the belt pulley a blade holder provided with a cutter is swung synchronously with the cam, a ratchet wheel supported on the machine frame is pushed by a ratchet pawl, the movement of the ratchet pawl is driven by the reciprocating rack, the gears and a rack bar slide plate are driven by the ratchet wheel. The utility model can be widely used as a machine for producing single plates of toothpicks or small round bars.
Description
The utility model relates to woodworking machinery, particularly produces the lath cutter of the veneer of toothpick or little pole.
At present, the veneer of producing toothpick or little pole generally all is to adopt peeler to process, and rotary-cut needs the large diameter tree material and stays reel (about diameter is φ 70mm) and can not utilize, and the waste of raw material is very big.And the cutting knife of existing lath cutter the time moves up and down in work, is cut and can not squeeze when flitch is done forward travel to the flitch cutting plate, and the plate face easily cracks during the cutting hard wood like this, and the plate rate of giving up is very high.
Task of the present utility model is: overcome the deficiencies in the prior art, design a kind of swing type lath cutter that cuts out smooth smooth, flawless production toothpick or little pole.
Task of the present utility model realizes as follows: the swing type lath cutter comprises frame, motor is housed in the frame, motor is by a pair of gear pair of belt transmission, with an end that is fixed with pull bar on the coaxial eccentric wheel of driven gear, the other end of pull bar links to each other with seesaw frame, the passive tooth wheel shaft rotates by belt pulley driving-belt moving cam, the knife rest that cutting knife is housed on it is swung synchronously with cam, the ratchet that is supported on the frame is promoted by ratchet, the motion of ratchet is driven by seesaw frame, the wheel and rack that constitutes kinematic pair with ratchet meshes, and is fixed with slide plate on the tooth bar.
The utility model is owing to be that cutter is swung when cutting plate, timber pumps around its radius of turn, ratchet system advances timber simultaneously, make a round trip and advance the cutting plate thickness of 2-8mm, pressure apparatus forms certain squeezing rate when timber is contacted with point of a knife, therefore smooth, the flawless of veneer smooth surface that cuts, as long as and can break the undersized log that becomes to meet the veneer width and can both be cut into veneer, so application surface is very wide.
Fig. 1 is the utility model front view.
A most preferred embodiment of the present utility model, as figure, lath cutter has a cuboid frame 17, the motor 1 that is installed in the frame drives driving gear 2 by pulley concial disk, gear 2 and driven gear 3 engagements, with an end that is fixed with pull bar 5 on the coaxial eccentric wheel 4 of driven gear 3, the other end of pull bar links to each other with seesaw frame 6, the seesaw frame upper surface has guide groove, the passive tooth wheel shaft drives cam 16 by belt pulley, the knife rest 15 that cutting knife 13 is housed above is rectangular slab, be positioned at above the cam and swing along with the rotation of cam, being positioned at has ratchet 7 and ratchet 8 on the frame, and ratchet 8 constitutes kinematic pair with gear 9, gear 9 meshes with tooth bar slide plate 10 simultaneously, and the effect of tooth bar slide plate is to promote flitch 12.On knife rest, be provided with nose bar 14.
The course of work of this device is: the motor rotation drives driving gear 2 and driven gear 3 makes eccentric wheel 4 drive seesaw frame 6 by pull bar 5, make ratchet 7 promote ratchet 8 driven gears 9 driving rack slide plates 10 simultaneously, promote flitch 12 to the previous crops intermittent movement by pushing away frame 11, flitch is done pumping around circumference in the seesaw frame guide groove, cut by cutting knife 13, produce pressure at the point of a knife position when nose bar 14 is cut into slices timber, reach certain squeezing rate.When opening in order to overcome timber and the cutter hub friction, knife rest 15 is also swing synchronously under the effect of cam 16, makes cutter hub leave timber.
Claims (2)
1, a kind of swing type lath cutter, it comprise frame and on cutting knife, it is characterized in that: the motor that is contained in the frame passes through a pair of gear pair of belt transmission, with an end that is fixed with pull bar on the coaxial eccentric wheel of driven gear, the other end of pull bar links to each other with seesaw frame, the passive tooth wheel shaft drives cam by belt pulley and rotates, the knife rest that cutting knife is housed on it is swung synchronously with cam, the ratchet that is supported on the frame is promoted by ratchet, the motion of ratchet is driven by seesaw frame, the wheel and rack that constitutes kinematic pair with ratchet meshes, and is fixed with slide plate on the tooth bar.
2, lath cutter as claimed in claim 1 is characterized in that: said seesaw frame upper surface has guide groove.
