Double face planer for processing bamboo flattening board
Technical field
The present invention relates to a kind of device for processing bamboo flattening board, it is a kind of double face planer for processing bamboo flattening board.
Background technology
The reasons such as the groove produced during by the bamboo flattening board of bamboo unwinder expansion due to tubercle, the expansion of bamboo unwinder are caused
Bamboo flattening board surface irregularity, this uneven transverse direction for not only showing bamboo flattening board, along bamboo flattening board length direction,
Due to bamboo is grown up, the thickness from head to afterbody gradually increases;Further, since stress reason, bamboo flattening board both sides
Easily to curls inward, head is easily upwarped, and problem above causes very big difficulty to processing bamboo flattening board.
The Chinese patent of Application No. CN104526779 discloses a kind of automation bamboo flattening board and removes blue or green de-etiolation double surfacer
Machine, blue or green de-etiolation is gone for bamboo section flattening plate.The double surfacer machine of CN104526779 has three rotors, preceding rotor and middle rotor
The front and rear bamboo of planing twice is blue or green, tabasheer of rear rotor planing;Before, middle rotor top help plane.
There are following problems in prior art:In the prior art, because the head of bamboo flattening board is easily upwarped, during cutting, head
Portion can depart from planing tool cutting point;Because bamboo flattening board surface thickness is uneven, the compressing member of prior art is when bamboo flattening board is compressed
Not enough laminating bamboo flattening board surface, can produce bossing press excessively and sunk part at all pressing less than situation, this
Sample does not only result in charging and has some setbacks, and causes cutting output inconsistent yet;Prior art is only arranged above compression in rotor
Part, compresses dynamics inadequate;Roughing and finishing are not differentiated between in the prior art, and the upper surface of bamboo flattening board has only carried out one
Bamboo flattening board surface quality after secondary processing, thus processing is not high;Prior art can not control the cutting output of bamboo flattening board.
The content of the invention
