Mechanism is equipped with pushing mechanism.
The operation principle of this programme is:Placement mechanism is supported plank for placing plank in irregular shape.It pushes away
Motivation structure is for pushing plank to be moved on placement mechanism.Driving mechanism is for driving driven roller to rotate, because of driven roller and idler wheel
Friction is affixed, therefore when driven roller rotation, frictional force is generated between the roll surface and idler wheel of driven roller, driven roller is driven by frictional force
Idler wheel rotates on holder.When initial, the axis of driven roller and the axis of idler wheel are simultaneously not parallel, the axis of driven roller and idler wheel
Axis have certain angle, therefore driven roller by frictional force drive idler wheel rotate while, idler wheel exists towards its swaying direction
It moves axially, is moved along the axial direction of driven roller to move rotating mechanism by supporting band, on rotating mechanism in driven roller
Nozzle paints to plank.In the left and right moving process of rotating mechanism, driving lever can be with slip limiting plate or fixed limit
Plate offsets, when driving lever and slip limiting plate are either fixed driving lever when limiting plate offsets and limited in fixed limiting plate or sliding
Position plate drives swivel becket rotation, swivel becket to rotate certain angle under the action of offseting, driving lever follows swivel becket to swing, together
When, driving lever drives follower lever to swing by tension spring, and follower lever drives turn disc, rotating disc to drive holder pivots, to
So that the idler wheel on holder is followed holder pivots, change swaying direction of the idler wheel in driven roller, keeps idler wheel anti-in driven roller

The distance between slip limiting plate and fixed limiting plate, when driving lever offsets with slip limiting plate or fixed limiting plate, spray
The moving direction of head just starts to change, therefore nozzle moves between slip limiting plate and fixed limiting plate, makes nozzle to plank
The position of different in width is painted, and prevents the part width of plank excessive, and the part of plank is caused to spray less than paint,
Or the part width of plank is too small, and so that paint is sprayed onto on the outside of plank and cause paint waste.Front limit column and rear limited post
