Above-mentioned frequency converter 48 is by integrated circuit chip IC, photoelectric tube GD, R ₄～R ₇And C ₃Form, 17,16,15,14,13,12,11,10,8,7,6,5 pin of IC respectively with LED ₁～LED ₁₂In corresponding light emitting diode link, 4 pin of IC are through the R of parallel connection ₄With C ₃Ground connection.Comprise in the above-mentioned controller 4 that power initiation circuit 44, induction regulator 45, speed control 46, one group of light emitting transistor are display leds ₁～LED ₁₂, power initiation circuit 44 is by transformer B ₁, bridge rectifier D, three terminal regulator T, voltage-stabiliser tube WD and C ₁Form, induction regulator 45 comprises transformer B ₂, potentiometer W ₁, W ₂And R ₁, C ₂, speed control 46 is by triode BG, potentiometer W ₃, R ₂, R ₃Form transformer B ₁Two input termination 110V AC powers, B ₁Output is imported three terminal regulator T, T output galvanic current and is pressed supply induction regulator 45, frequency converter 48 after bridge rectifier D rectification, and the potentiometer W in the induction regulator 45 ₂Adjustable end and 3 pin of frequency converter 48 link, triode BG base stage meets photoelectric tube GD in the frequency converter 48 in the described speed control 46.

The utility model course of work describes in conjunction with Fig. 1,2,4:

Starter M ₁Saw blade axis 11 is rotated to drive saw blade, motor M ₂Drive the lifting of pressure roller wedge 20, motor M ₃Drive saw blade axis 11 liftings, and motor M ₄Make rolling wheel set 21 and delivery wheel 12 do to rotate synchronously by rolling wheel set Universal linking lever 24 and delivery wheel Universal linking lever 36, make timber 50 can obtain synchronous driving.By fluctuating orbit 25, so that according to the thickness of desiring sawing timber 50, set the distance between rolling wheel set 21 and the delivery wheel 12, and cooperate the velocity of rotation of saw blade axis 11, smooth and easy sawing timber 50.The lifting of saw blade axis 11 impels lifting shaft rod 14 to rotate and adjust the sawing height of saw blade 51.Starter M ₄And drive each Universal linking

lever

24,25, thus rolling wheel set 21 and delivery wheel 12 are rotated synchronously, referring to Fig. 1, Fig. 2 and Fig. 4.

Delivery platform 30 is in order to carry timber 50, and delivery wheel 12 is exposed to the surface of delivery platform 30, be to place with rolling wheel set 21 symmetries, and by same motor M ₄Drive, make it do to rotate synchronously, thereby timber 50 is carried out synchronous transport with rolling wheel set 21.Each rolling wheel set 21 is all joined a compression spring 22, makes timber 50 carry out sawing in the space of allowing by compression spring 22, even there is thicker timber 50 to send into, rolling wheel set 21 makes thicker timber 50 still can send into sawing by the retraction of compression spring 22.When preventing sawing, timber 50 ejects and injures operating personnel, so the side is provided with safety guard 33, and at front end feeding port 32 places security fence 31 is housed, with protection operating personnel's safety.Also be provided with suction port 23 on roll-in seat 20, the dirt that is produced when being used to absorb sawing bits are in order to avoid pollute.The power set of main frame 10 cooperate frequency conversion main part 4 and controller 40 to carry out the conversion adjusting to transporting velocity.

Be provided with button 43 in the controller 40 of the present utility model, with control motor M ₁～M ₄Start and stop, and on controller 40, be provided with one group of light emitting diode indicator LED ₁～LED ₁₂, when sawing timber, surpass the load set, LED ₁～LED ₁₂In a corresponding display lamp then ignite.Like this, operating personnel can learn that the timber 50 of institute's sawing is thicker than former timber.Be provided with a frequency conversion main part 4 in the utility model, in frequency conversion main part 4, be provided with frequency converter 48, utilize cooperating of frequency converter 48 and each electronic control system, make the utility model allowing in the space 12 of rolling wheel set 21 and delivery wheels, in the thickness range that allows sawing timber 50, can both carry out sawing by saw blade 51, its transporting velocity can be adjusted by speed governing button 41, therefore after timber 50 is admitted to sawing, when the wood chip of saw blade 51 sawings get rid of not as good as and load when excessive, main frame 10 can import the rapid induction of this situation in the frequency conversion main part 4 into, adjust sawing and transporting velocity via inner frequency conversion system at once and make sawing work recover normal, unlikelyly cause machine to stop or breaking down.

Referring again to Fig. 6, delivery wheel 12 tops that expose on the delivery platform 30 are arranged with rolling wheel set 21, and air compressing cylinder 26 is housed respectively on the transmission spindle 27 of rolling wheel set 21 or compresses spring 22, and in 21 of per two rolling wheel set by central shaft 28 as fulcrum, give by controller 40 earlier and earlier the transporting velocity at initial stage being set, after the start, send into timber 50, referring to Fig. 4, sawing is carried in clamping by delivery wheel 12 and rolling wheel set 21, the space is regulated according to the thickness of timber 50 by compression spring 22 and air compressing cylinder 27 again, carried out last sawing afterwards again.In case the thick thin degree difference of timber 50 is bigger, when causing saw blade 51 sawing live loads big, frequency conversion main part 4 can perceive rapidly, then reduces the transporting velocity (because of during frequency conversion main part 4 all is ready at any time) of delivery wheel 12 immediately, so that make sawing recover normal.

The utility model is by frequency conversion main part 40 perception sawing situations conversion transporting velocity at any time, and controller then shows saw cutting load, is beneficial to sawing, and this has not only simplified operation sequence greatly and reduces labor intensity, and makes the also corresponding minimizing of fault rate of machine.Thereby improved the production efficiency of sawing wood chip, and alleviated the maintenance capacity of production of machinery producer.
