Description

Automatic sawing machine

The utility model relates to car wood lathe, is mainly used in the car wood processing of wooden worker's festival product.

In the processing of wooden process gift (as the christmas crafts gift etc.), generally need to use Che Muji more.Che Muji can be divided into foot-operated and electronic two classes, and bicycle wood machine is because labour intensity is big, and work efficiency is low, is eliminated gradually.And existing electric motor car wood machine, the major defect of its existence is: only replaced riding by motor, automaticity is low, needs hand charging, be behind one of the per car, need artificial material loading, discharging, therefore, troublesome poeration, operating efficiency are still on the low side, have increased processing charges.Simultaneously, human body easily sucks wood dust, influences operator ' s health.

The purpose of this utility model is the Che Muji of a kind of self-feeding of design, material folding, discharging, automatic cutting.

The utility model from the technical scheme of motor-car wood machine is: be made up of institutes such as support, motor, feed mechanism, electrical equipment control mechanism, anchor clamps and knife rests, on support, be installed into hopper, under the feed hopper conveying pipeline is arranged, feeding rod is arranged in the conveying pipeline, feeding rod is by driven by motor, the conveying pipeline connecting clamp has length adjuster on the other end of support.

Compared with the prior art of the present utility model, have automaticity height, production efficiency height from motor-car wood machine, alleviated labor intensity of operating staff, and can make operating personnel away near the Che Muji, avoids sucking wood dust, good for health.

Fig. 1 is that the utility model is from motor-car wood machine schematic diagram;

Fig. 2 is that the utility model is from the dynamo-electric device control circuit figure of motor-car wood.

Below in conjunction with Fig. 1-Fig. 2 the utility model is done detailed explanation from the embodiment of motor-car wood machine.

1, support; 2, feeding motor; 3, feeding start-stop lock; 4, feeding rod; 5, belt pulley; 6, timber; 7, feed hopper; 8, conveying pipeline; 9, kill car; 10, clutch lever; 11, electromagnet; 12, clutch; 13, anchor clamps; 14, knife rest; 15, length adjuster; 16, limit switch; 17, handwheel; 18, feeding separator; 19, decelerator; 20, adjuster feeds, falls back; 21, cutting motor; 22, distribution box; 23, Che Muzhu motor.

The utility model discloses a kind of from motor-car wood machine, timber 6 is dropped into from feed hopper 7, timber wherein one fall in the conveying pipeline 8, feeding motor 2 on the support 1 drives belt pulley 5, and after belt pulley rotated, the feeding rod 4 in the belt pulley was screw rods, feeding spiro rod is done forward and backward motion, promotion timber advances, and send the distance of timber, is limited the stroke of feeding rod by feeding start-stop lock 3.Ground of timber is sent to anchor clamps 13, run into length adjuster 15 after, the lathe tool in the knife rest 14 under the transmission of cutting motor 21, the cutting timber.Length adjuster 15 is to be determined by limit switch 16 and handwheel 17 according to the difference of timber length.

Below introduce the course of work of each mechanism by electrical equipment control:

After timber 6 was put into feed hopper 7, the K that closes a switch connected power supply, presses firing switch (normal open switch) STA, and circuit control path is (as shown in Figure 2): first → SLC → STA → SQA → second, SLC adhesive, SLC ₄Self-locking, SLC ₃Relay switch is connected, and Che Muzhu motor 23 is just changeing.

SLC is a relay; SQA is shutdown switch (the total guard's valve of control power supply); SLC ₄Be the relay normally open switch; SLC ₃Be the relay normally open switch.

Connecing above-mentioned automatically-controlled continuous circuit paths is: first → EB ₄→ EQA → YC ₄→ ELC → third → SLC ₄→ SQA → second, ELC adhesive, ELC ₃Relay switch is connected, and feeding motor 2 is just passing on material, when timber 6 is delivered to length adjuster switch YXK ₂Till the adhesive.

EB ₄Be the relay normally closed switch; EQA is travel switch (feeding rod fall back starting brake); YC ₄Be the relay normally closed switch; ELC is that the feeding motor is just changeing relay.

Connecing above-mentioned automatically-controlled continuous circuit paths is: first → YXK ₁→ YXK ₂→ YC → third → SLC ₄→ SQA → second, YC ₂Adhesive, YC ₅Self-locking, clutch 12 adhesives, YC ₁Closure, YC ₄Disconnect, feeding motor 2 stops feeding.

YXK ₁Be travel switch, when feeding, electromagnet 11, cutting motor 21 suspend (normally closed); YXK ₂Be travel switch, length adjustment, electromagnet, cutting motor, firing switch (often opening); YC is that clutch 12 absorbs relay; YC ₂Be the clutch normal open switch; YC ₅Be the relay normally open switch; YC ₁The relay normally open switch.

Connecing above-mentioned automatically-controlled continuous circuit paths is: first → ZC → FC ₁→ FXK ₂→ YC ₁→ the third → SLC ₄→ SQA → second, cutting motor 21 is just changeing, and knot advances beginning, car wood cutting forming, car proceeds to by-pass cock FXK ₂Disconnect FXK ₁Till the closure.

ZC is that cutting motor is just changeing relay; FC ₁Be the normally closed office of relay; FXK ₂For cutting motor feeds limit switches; YC ₁Be the relay normally open switch.

Connecing above-mentioned automatically-controlled continuous circuit paths is: first → FC → ZC ₁→ ZXK ₁→ FXK ₁→ the third → SLC ₄→ SQA → second.FC ₁Self-locking, the cutting motor counter-rotating falls back, and falls back on by-pass cock ZXK ₁Till the disconnection, FC decontrols, (FXK ₁, FXK ₂With ZXK ₁Switch lacks different adjustment greatly according to process).FC is a cutting motor counter-rotating relay; ZC ₁Be the relay normally closed switch; ZXK ₁Be the cutting motor limit switches that fall back; FXK ₁For cutting motor feeds limit switches.

Connecing above-mentioned automatically-controlled continuous circuit paths is: first → ZC → FC ₁→ FXK ₂→ YC ₁→ the third → SLC ₄→ SQA → second, lathe tool feeds, and row partways, and just cutter is in the both sides of car timber, by mechanical feed separator 18 and feeding pause switch YXK ₁Contact disconnects, and clutch 12 is put, and cutting motor 21 begins to continue to feed car wood.

If one of timber has sent, stop by the tail end of feeding rod 4 and feeding that lock contacts EQA, ETA, ELC stops, the control circuit path is: first → ETA → EQA → ELB → third → SLC ₄→ SQA → second.EB ₄Separate EB ₅Self-locking, the counter-rotating of feeding motor, feeding rod falls back, and falls back on the starting point end of feeding rod, and EQB disconnects, and the counter-rotating of feeding motor stops.

ETA is the feeding rod firing switch that falls back; EQB is the feeding rod limit switches that fall back; ELB is feeding motor counter-rotating relay; EB ₅Be the relay normally open switch.

Connecing above-mentioned automatically-controlled continuous circuit paths is: first → EB ₄→ EQA → YC ₄→ ELC → third → SLC ₄→ SQA → second.The feeding motor just changes, and begins to continue feeding, and periodic duty has so again and again just realized from motor-car wood.
