Description
Technical field
The invention belongs to a kind of wood processing equipment, specifically, particularly relate to a kind of plate 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 mainly been used on center veneer lathe, the advantage of its rotary-cut wood skin: the uniformity, fineness are good, and intensity is high, and veneer is without dorsal fissure phenomenon; Shortcoming: because being that power drive timber rotates by axis, finally can remain the reel being greater than axis diameter (75mm), remaining reel needs to be transported to card-less rotary cutter secondary operations, wastes time and energy and accounts for place more.Circle in-wheel driving nose bar is mainly used in without on cassette peeler, and its advantage wood spool rotary-cut to diameter about 26mm, can improve timber utilization rate, increase economic efficiency, and also has material loading convenient simultaneously, is easy to operation, save the advantages such as manpower; Shortcoming: veneer uniformity ratio has center veneer lathe poor, the wooden skin dorsal fissure of more than 2.2mm is serious, and single plate intensity is poor, waste glue.Existing rotary trunk-layer stripping machine without clamper drives log to rotate rotary cut venner with three of structure distribution triangular in shape friction rollers.Rotary trunk-layer stripping machine without clamper is when driving log to rotate, and the point of contact, the center of circle of three friction wheel axles and the log power that is squeezed is maximum.Peeling knife according to single friction roller thickness, under cutting between 5-20mm.The surface smoothness perfect condition of rotary-cut wood skin 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 by partly cutting partly to tear, veneer is scaled off, and veneer reverse side fiber is caused veneer rough surface because do not cut completely.But reality be subject to the peeling knife that affects of circle in-wheel driving pressure-bar structure can not too close to log and roller bearing tangent line place.A kind of scheme that can solve above-mentioned card-less rotary cutter shortcoming is not also had in prior art.
Summary of the invention
The object of the invention is to provide a kind of plate nose bar card-less rotary cutter, to overcome the defect of the serious and intensity difference of veneer that in prior art, rotary trunk-layer stripping machine without clamper rotary-cut goes out wood skin dorsal fissure.
The present invention realizes by the following technical solutions: a kind of plate nose bar card-less rotary cutter, comprise frame, frame is provided with positioning drive mechanisms, feed mechanism and peeling knife assembly, described positioning drive mechanisms comprises the first driven roller of structure distribution triangular in shape, the second driven roller and the 3rd driven roller, also comprise plate nose bar assembly, the roller central point of described 3rd driven roller is positioned at the top at plate nose bar component palette edge; The blade part of described peeling knife assembly is positioned at the below of the roller central vertical horizontal center line of described first driven roller and the second driven roller.
The edges of boards of described plate nose bar assembly are along the roller central vertical horizontal center line 8mm scope be positioned at apart from described first driven roller and the second driven roller.
Described feed mechanism comprises the 3rd drive motors, screw rod propulsive mechanism and horizontal guide rail, and described 3rd drive motors is connected with screw rod propulsive mechanism, and described screw rod propulsive mechanism is also connected with described peeling knife assembly, and described peeling knife assembly is arranged on horizontal guide rail.
The roller surface of described first driven roller, the second driven roller and the 3rd driven roller is provided with friction line.
Compared with prior art, the beneficial effect of the invention is: the present invention includes two kinds of pressure-bar structures, i.e. fixed head nose bar and roller shaft nose bar, plate nose bar is fixed below single roller shaft, allow rotary-cut blade and log tangent, cutting near fixed head nose bar extruding force maximum point place, the veneer fineness that rotary-cut goes out is more, the uniformity is high, dorsal fissure reduces by 95%, improves economic benefit.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As Fig. 1, shown in Fig. 2, a kind of plate nose bar card-less rotary cutter, comprise frame 1, frame 1 is provided with positioning drive mechanisms, feed mechanism, plate nose bar assembly 6 and peeling knife assembly 7, driving mechanism comprises the first driven roller 2, second driven roller 3 and the 3rd driven roller 5, first driven roller 2, second driven roller 3, 3rd driven roller 5 structure distribution triangular in shape, first driven roller 2, second driven roller 3 respectively with the first drive motors 8, second drive motors 9 connects, its main effect is stationary positioned log 4 and is log transmitting rotary power, first driven roller 2, the roller surface of the second driven roller 3 and the 3rd driven roller 5 is equipped with the friction line increased with log 4 frictional force.
Plate nose bar assembly 6 is the elongated steel sheet of length slightly larger than processing log 4 length, the perfect condition on the edges of boards edge of plate nose bar assembly 6 is squeezed in log 4 horizontal center line place, extrusion position may also be within the scope of the roller central vertical horizontal center line 8mm of described first driven roller 2 and the second driven roller 3, and within the scope of this, the quality influence of rotary-cut to veneer is little; The roller central point of the 3rd driven roller 5 is positioned at the top on the edges of boards edge of plate nose bar assembly 6, below the roller central vertical horizontal center line that the blade part of peeling knife assembly 7 is positioned at described first driven roller 2 and the second driven roller 3 and plate nose bar assembly 6, select the position of peeling knife assembly 7 blade according to the thickness of rotary-cut sheet material, the blade of sheet material thicker peeling knife assembly 7 and the spacing between the first driven roller 2 and the roller central vertical horizontal center line of the second driven roller 3 larger.
Feed mechanism comprises the 3rd drive motors 10, screw rod propulsive mechanism 11 and horizontal guide rail, 3rd drive motors 10 is connected with screw rod propulsive mechanism 11, described screw rod propulsive mechanism 11 is also connected with described peeling knife assembly 7, peeling knife assembly 7 is arranged on horizontal guide rail, and screw rod propulsive mechanism 11 provides centripetal force for the cutting of peeling knife assembly 7.
Operation principle of the present invention: the first driven roller 2, second driven roller 3 drives as log 4 provides power rotatably by motor, plate nose bar assembly 6 provides extruding force for peeling knife assembly 7 cuts log 4, feed mechanism provides the centripetal force of rotary-cut for peeling knife assembly 7, at the extruding force effect backspin cutter assembly 7 of plate nose bar assembly 6 and the 3rd driven roller 5, the log 4 of rotation is peeled into plank.Because plate nose bar assembly 6 extruding force application point is close to the line of cut of peeling knife assembly 7, therefore the veneer fineness that goes out of rotary-cut and the uniformity are all improved, and dorsal fissure phenomenon can reduce by 95%.
