As shown in Figure 5, sprocket wheel 7 in described two chain wheel driving mechanisms 5 is respectively drive sprocket 8 and by movable sprocket 9, described drive sprocket 8 is at the same end of two chain wheel driving mechanisms 5, drive sprocket axle 10 lower ends of two drive sprocket 8 respectively are provided with a speed governing synchronous motor 23, establish motor speed sensor 24 on the axle of speed governing synchronous motor 23.
When device start, regulate the rotating speed of speed governing synchronous motor 23, realize rotation synchronously; In operation process, if asynchronous, motor speed sensor 24 will send signal, two speed governing synchronous motors 23 can automatically be adjusted rotating speed separately, achieve synchronously.
Embodiment six
Another major issue among the present invention is processed timber 4 must be clamped solid and reliablely, and the mode that present embodiment provides is:
As shown in Figure 3, Chain plate on the described chain 6 and the side that processed timber 4 contacts are provided with zigzag, and zigzag straight flange, towards the feed direction of processed timber 4.
Adopt profile of tooth on the side that chain 6 is contacted with timber, make profile of tooth can embed processed timber 4, it is clamped securely, and can produce the power of feeding, be unlikely making chain 6 on processed timber 4, produce slip.
Embodiment seven:
The purpose identical with embodiment five must make the processed timber 4 of chain 6 firm grip, and present embodiment is by the structure of chain push pedal.Specific practice is:
On described chain wheel driving mechanism 5, its chain 6 and the opposite side of processed timber 4 contacts are provided with chain push pedal 13, with chain 6 parallel and contacts, in the back of chain push pedal 13, establish the push pedal cylinder 14 that is fastenedly connected with feed system backbar 1.
At each chain wheel driving mechanism 5 a plurality of chain push pedals 13 can be set; The back of each chain push pedal 13 can be provided with the two ends of two push pedal cylinders 14 and close each chain push pedal 13 in daytime; Adopt push pedal connector 20 to be articulated and connected between the chain push pedal 13.Push pedal connector 20 guarantees slip smooth-going of chains 6, is unlikely in the junction of two chain push pedals 13 and produces stuck phenomenon.
Near the drive sprocket 8 on the chain wheel driving mechanism 5 with by chain push pedal 13 ends of movable sprocket 9, respectively be provided with supporting roller 19, make chain 6 turning to when beginning to touch the position of chain push pedal 13, be unlikely by chain push pedal 13 ends and block.
Owing to adopted said structure, so under machining state, the piston rod in the described push pedal cylinder 14 is pushed chain push pedal 13 to chain 6, chain 6 is closely contacted with processed timber 4, make the processed timber 4 can be along with chain 6 one motion.
Utilize the advantage of push pedal cylinder 14 to be: can realize overload protection; The size control and regulation of motive force are convenient; Each push pedal cylinder 14 action all can be harmonious.
Certainly, push pedal cylinder 14 also can make hydraulic cylinder into.Accompanying drawing has only been expressed the structure that adopts push pedal cylinder 14.It is similar adopting the structure of hydraulic cylinder.
No matter adopt Pneumatic Transmission still to adopt hydraulic drive, all corresponding power source to be arranged, promptly air pump or hydraulic pump also will have corresponding pipeline and control element, make it constitute air pressure or hydraulic control circuit and control system.
Embodiment eight:
Present embodiment guarantees chain push pedal 13 when being subjected to the impetus of push pedal cylinder 14 or hydraulic cylinder, and its motion is to guarantee to make chain 6 to press processed timber 4, and present embodiment has adopted guide rail structure, and concrete mode is:
Push pedal guide rail 15 is established in described chain push pedal 13 belows, and described push pedal guide rail 15 is vertical with chain push pedal 13, and described chain push pedal 13 bottoms form guide rail with push pedal guide rail 15 and cooperate, and the motion of chain push pedal 13 is subjected to the constraint of push pedal guide rail 15.
Embodiment nine:
Present embodiment is the exemplifying embodiment different with embodiment six and embodiment seven.Present embodiment adopts the mode of sprocket wheel pushing tow chain, reduces the wearing and tearing of chain 6 and chain push pedal 13.As shown in Figure 4, its structure is:
On described chain wheel driving mechanism 5, its chain 6 and the opposite side of processed timber 4 contacts, if clamping sprocket wheel 16 with chain 6 engagements, if hold out against cylinder 17, the axle of described clamping sprocket wheel 16 is fixed on the piston rod that holds out against cylinder 17, under machining state, the described piston rod that holds out against in the cylinder 17 will clamp sprocket wheel 16 and push chain 6 to, and chain 6 is closely contacted with processed timber 4.
Certainly, identical with embodiment six, hold out against cylinder 17 and also can change hydraulic cylinder into.Advantage and effect are referring to embodiment six.The side of piston rod should be provided with block, prevents that it is subjected to cross force and bending.
Embodiment ten:
Drive sprocket 8 in described two chain wheel driving mechanisms 5 all is located at the end of chain wheel driving mechanism 5 feeding directions of feed.
Like this, as long as drive sprocket 8 rotates, clamp the chain 6 of processed timber 4 one sides, what necessarily be subjected to is pulling force, makes clamping force that produces on the chain wheel driving mechanism 5 and the power of sending to forward be delivered to processed timber 4 better and gets on.
In conjunction with the accompanying drawings the present invention has been carried out exemplary description above; obviously specific implementation of the present invention is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or design of the present invention and technical scheme are directly applied to other occasion without improving, all within protection scope of the present invention.
