Description
Technical field
The invention belongs to a kind of wood processing equipment, specifically, particularly relate to a kind of compound nose bar card-less rotary cutter.
Background technology
At present, the timber lathe on market has two kinds of pressure-bar structures, i.e. board-like fixing nose bar and circle in-wheel driving nose bar. Board-like fixing nose bar has been used primarily on center veneer lathe, the advantage of its rotary-cut veneer: the uniformity, fineness are good, and veneer is without dorsal fissure phenomenon, and intensity is high; Shortcoming: because having axis is that power drive timber rotates, finally remaining the reel more than card shaft diameter (75mm), remaining reel needs to be transported to card-less rotary cutter secondary operations, time-consuming and account for place more. Circle in-wheel driving nose bar is used primarily in without on cassette peeler, and its advantage is wood spool rotary-cut to diameter about 26mm, can to improve timber utilization rate, increase economic efficiency, and also has feeding convenient, it is easy to operation simultaneously, saves the advantages such as manpower; Shortcoming: veneer uniformity ratio has center veneer lathe poor, the veneer dorsal fissure of more than 2.2mm is serious, and single plate intensity is poor, wastes glue. Existing rotary trunk-layer stripping machine without clamper is to drive log to rotate rotary cut venner with three friction rollers of structure distribution triangular in shape. Rotary trunk-layer stripping machine without clamper is when driving log to rotate, and three friction wheel axles and the point of contact, the center of circle of the log power that is squeezed is maximum, and peeling knife is according to single friction roller thickness, under cutting between 5-20mm. The surface smoothness perfect condition of rotary-cut veneer is that peeling knife cuts at log and roller bearing tangent line place (extruding force maximum point), if peeling knife leaves extruding point, peeling knife is then veneer is scaled off by partly cutting partly to tear, and veneer reverse side fiber is not because being caused veneer rough surface by cutting completely. But reality is to receive to be subject to affecting peeling knife and can not being too close to log and roller bearing tangent line place of circle in-wheel driving pressure-bar structure. But without a kind of scheme that can solve the problem that above-mentioned card-less rotary cutter shortcoming in prior art.
Summary of the invention
It is an object of the present invention to provide a kind of compound nose bar card-less rotary cutter, poor with the veneer uniformity overcoming rotary cutter without clamping in prior art, veneer dorsal fissure is serious, and single plate intensity is poor, the defect of waste glue.
The present invention realizes by the following technical solutions: a kind of compound nose bar card-less rotary cutter, including frame, frame is provided with positioning drive mechanisms, feed mechanism and peeling knife assembly, described positioning drive mechanisms includes the first driving roller of structure distribution triangular in shape, second drives roller and compound nose bar, described compound nose bar includes spaced plate nose bar and roll-in chi, the centrage of described roll-in chi is positioned at the top at plate nose bar component palette edge, the blade part of described peeling knife assembly is positioned at the lower section of the described first roller central vertical horizontal center line driving roller and the second driving roller.
The edges of boards of described plate nose bar are within the scope being positioned at from the described first roller upper and lower 8mm of central vertical horizontal center line driving roller and the second driving roller.
Described first drives the roller surface of roller, the second driving roller and roll-in chi to be provided with form friction pattern.
Compared with prior art, be the invention has the beneficial effects as follows: the present invention is compounded on a machine axial compression chi of the fixing board-like nose bar and card-less rotary cutter that have center veneer lathe and uses, therefore the advantage that the present invention has concentrated board-like fixing nose bar and axial compression chi, not only avoid center veneer lathe residue reel needs transhipment to carry out the defect of secondary operations, and the mass defect that the veneer avoiding rotary cutter without clamping exists, the veneer that its rotary-cut goes out is highly polished, dorsal fissure reduces by 95%, the uniformity is high, both improve economic benefit, improve again the quality of veneer.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Such as Fig. 1, shown in Fig. 2, a kind of compound nose bar card-less rotary cutter, including frame 1, frame 1 is provided with positioning drive mechanisms, feed mechanism and peeling knife assembly 6, positioning drive mechanisms includes the first driving roller 2 of structure distribution triangular in shape, second drives roller 3 and compound nose bar 5, compound nose bar 5 includes spaced plate nose bar 8 and roll-in chi 7, first drives roller 2, second drives connection on roller 3 to drive roller motor 11, connection roll nose bar motor A9 and roll-in chi motor B10 on roll-in chi 7, first drives roller 2, second drives the roller surface of roller 3 and roll-in chi 7 to be provided with increases its form friction pattern with log 4 frictional force.
Owing to plate nose bar 8 and the roll-in chi 7 extruding point on log 4 can not point-blank, therefore the centrage of roll-in chi 7 to be arranged on the top on plate nose bar 8 edges of boards edge; In order to rotary-cut goes out veneer, the blade part of peeling knife assembly 6 to be located at the lower section of the roller central vertical horizontal center line of the first driving roller 2 and the second driving roller 3, thickness according to rotary-cut plank selects peeling knife assembly 6 blade distance from the first roller central vertical horizontal center line driving roller 2 and the second driving roller 3, the thickness of rotary-cut plank is more thick, and the blade distance from centrage is more big; The perfect condition on the edges of boards edge of plate nose bar 8 is to be squeezed in log 4 horizontal center line place, within extrusion position may also be the scope from the described first roller central vertical horizontal center line 8mm driving roller 2 and the second driving roller 3, within the scope of this, the quality of veneer is affected little by rotary-cut.
The operation principle of the present invention: plate nose bar 8 of the present invention and roll-in chi 7 are combined with each other and are applied on a peeler, and plate nose bar 8 and roll-in chi 7 interval are arranged side by side composition compound nose bar 5, first drives roller 2, second to drive roller 3 and roll-in chi 7 to be driven to log 4 by motor and provide power rotatably, plate nose bar 8 cuts log 4 for peeling knife assembly 6 to be provided from the extruding force close to the line of cut, feed mechanism provides the centripetal force of rotary-cut for peeling knife assembly 6, and the log 4 of rotation is peeled into plank by the extruding force effect backspin cutter assembly 6 at plate nose bar 8 and roll-in chi 7. Therefore the veneer thickness uniformity being cut is high, intensity is high, phenomenon without dorsal fissure produces, roll-in chi 7 and first drives roller 2, second to drive roller 3 and roll-in chi 7 to be log 4 transmitting rotary power simultaneously, can be implemented in log 4 is switched to diameter 26mm by a machine, it is to avoid the waste of timber and secondary transhipment cutting.
