Five, the specific embodiment:

Below in conjunction with accompanying drawing the present invention is further specified:

As shown in Figure 1, the present invention includes transport portion 1, cutting part 2, output 3, motor 4 and speed setting controller 5.The front end of the transport portion port of export 6 is provided with Cutting platform 7, and cutting part 2 is positioned at Cutting platform 7 tops, and output arrival end 8 is positioned at Cutting platform 7 belows.Said cutting part 2 comprises square knife rest 9 and is fixed on the cutting tool 10 on the square knife rest 9.Motor 4 is connected with square knife rest rotating shaft 17 through transmission device 18.The speed of speed setting controller 5 control motors 4 rotating speeds.

Motor 4 is connected with rotating shaft 17 on the square knife rest 9 through transmission device 18, like this, the rotation of the rotating band movable knife rack 9 of motor 4, the rotation of the rotation drive cutting tool 10 of knife rest 9 reaches the purpose of cutting veneer 16.Cutting tool 10 is in rotation process, and its rotation period is divided into cut length and non-cut length.Moment before the cutting, the contact point of cutting tool 10 and veneer 16 is positioned at the front portion at Cutting platform 7 edges, and preferably its contact point is positioned at from the nearer position of Cutting platform 7 edges.When cutting, cutting tool 10 begins to cut the veneer 16 that is positioned at Cutting platform 7 front portions from the contact point with veneer 16, and transport portion need not pause in cutting process; Cut veneer 16 Deng cutting tool 10; Cutting tool 10 is rotated further and gets into non-cut length because the speed of transport portion 1 transporting thin plank 16 is certain, cutting tool 10 rotate non-cut length during this period of time in; Transport portion 1 continues to the uncut veneer 16 of Cutting platform 7 anterior conveyings; When rotating to the contact point with veneer 16, get into the cut length of next round, by that analogy Deng cutting tool 10.Because in cut length and non-cut length process, transport portion 1 moves and do not stop always,, improved production efficiency so production line does not need to pause.

Speed setting controller 5 is controlled the rotating speed of knife rest 9 and cutting tool 10 through the rotating speed of control motor 4.Because transport portion 1 transfer rate confirms that veneer 16 just confirms also that through the speed of Cutting platform 7 rotating speed of controlling motors 4 through speed setting controller 5 just can cut out satisfactory veneer 16.For example: cut the length of veneer 16 if desired when longer, speed setting controller 5 is slow with the rotating speed control of motor 4, and the rotary speed of cutting tool 10 also just slowly, just can be cut the veneer 16 of length like this; If desired veneer 16 length of cutting more in short-term, speed setting controller 5 with the control of the rotating speed of motor 4 hurry up, the rotary speed of cutting tool 10 just can be cut the veneer 16 than weak point also just hurry up like this.

The transmission device 18 that connects motor 4 and square knife rest 9 can be that any transmission devices that can reach accurate transmission such as toothed timing belt, chain can.For example: if transmission device 18 employings is chain, knife rest rotating shaft 17 is provided with sprocket wheel, and an end of chain is connected with motor 4, and the other end is connected on the sprocket wheel, reaches to drive the purpose that cutting tool 10 rotates.If what transmission device 18 adopted is toothed timing belt, knife rest rotating shaft 17 is provided with toothed wheel, and an end of toothed timing belt is connected with motor 4, and the other end is connected on the toothed wheel, reaches to drive the purpose that cutting tool 10 rotates.The top of the transport portion port of export 6 also is provided with contact roller 14, and its effect is that the veneer that sends 16 is flattened, and prevents veneer 16 perks in cutting process simultaneously, is convenient to cutting tool 10 cuttings.

As shown in Figures 2 and 3, transport portion 1 with output 3 so long as can realize the device of continuous conveying and get final product, for example: ribbon conveyer, roller conveyor, chain transfer etc.Simple in structure and cost is lower because of ribbon conveyer, what general transport portion 1 and output 3 adopted is ribbon conveyer, and ribbon conveyer comprises driving wheel 11 respectively; 19,

follower

12,20 and be arranged on driving wheel and the follower outer surface on

conveyer belt

13,21; Driving wheel 11; 19 rotation drives the rotation of

follower

12,20 through conveyer belt 13,21.Transport portion 1 is sent to cutting part 2 through the veneer 16 that conveyer belt 13 will not meet dimensional requirement, and output 3 transfers out the cutting workspace through conveyer belt 21 with the veneer 16 of well cutting.

Like Fig. 4 and shown in Figure 5; Cutting part 2 comprises square knife rest 9 and is arranged on the cutting tool 10 on the square knife rest; Cutting tool 10 is through being bolted on the square knife rest 9; What adopt square knife rest 9 is for the ease of fixing cutting tool 10, and cutting tool 10 is not shifted in the rotation cutting.The wearing and tearing because cutting tool 10 deforms in long-time cutting process easily are close to veneer 16 in order to ensure blade and are cut, and the screw 15 on the square knife rest 9 is set to long looping pit, are convenient to regulate cutting tool 10 position on square knife rest 9.

Consider that the transport portion port of export 6 upper ends also are provided with a contact roller 14; When the ironed plank 16 of contact roller 14; Can give transport portion driving wheel 11 1 pressure, so transport portion driving wheel 11 is compared the diameter of contact roller 14 than big, to bear pressure with the diameter of follower 12.And 3 of outputs transmit veneer 16, and for reducing cost, the diameter of output driving wheel 19 and follower 20 is smaller with respect to the diameter of transport portion driving wheel 11 and follower 12.

During work; When the veneer 16 that the conveyer belt 13 of transport portion 1 will not meet size earlier is transported to the port of export 6; Contact roller 14 compresses the veneer that sends 16 and makes it smooth; The veneer 16 of compacted mistake is sent to Cutting platform 7 front ends, and the cutting tool 10 that is positioned at Cutting platform 7 tops is along with knife rest 9 rotations are cut veneer 16.The movement locus plane that cutting tool 10 rotates on knife rest 9 is vertical with Cutting platform 7, guarantees that like this 10 pairs of veneers of cutting tool 16 carry out perpendicular cuts, and it is identical to carry out the effect of perpendicular cuts with the hydraulic drive cutter in cutting effect and the prior art.Because knife rest 9 is continuous rotations together with cutting tool 10, thereby transport portion 1 does not need to pause in cutting process, has improved production efficiency.The veneer 16 of well cutting falls into output arrival end 8, cuts working regions by veneer 16 outputs that output conveyer belt 21 will cut.Whole device delivery part 1, cutting part 2, output 3 are mounted on the support.

The present invention mainly is matched in rotary-cut veneer processing machine and other veneer manufacturing machine, the veneer of producing is cut into the size that needs.This invention becomes the continous way cutting through improving cutting mode with original fluid pressure type plank cutting, has improved the production efficiency of such wood processing enterprise.
