Description
Technical field
The present invention relates to woodworking machinery, specifically a kind of device for preventing bending of numerical control hydraulic double-chucking shaft rotary cutter.
Background technology
It is well known that numerical control hydraulic double-chucking shaft rotary cutter is in rotary cut venner, it is equal in order to ensure the veneer thickness that rotary-cut goes out
Even, plate face is not broken, and device for preventing bending of numerical control hydraulic double-chucking shaft rotary cutter is generally provided with body, and it includes lifting bracket, returns
Rotating shaft, rotary support, lift cylinder, upper anti-roller and lower anti-roller,
Lifting bracket is located at body top, and lifting bracket is provided with gyroaxis, and gyroaxis is provided with rotary support, on rotary support
Anti- roller and lower anti-roller are provided with, gyroaxis one end is provided with, lift cylinder drives gyroaxis motion, in driving anti-bending roll-in to lean on
On reel, reel is rotated and drives anti-bending roller to rotate, and prevents reel from bending, and the substantive deficiency of this structure is：Due to anti-roller
Adjust automatically angle can not be gradually reduced according to reel diameter, and anti-roller contacts uneven with reel, anti-bending poor performance, prevents
Roller and reel frictional force are big, and rotary resistance is big, when reel diameter very little or reel surface nodosity, the easily stalling of anti-roller or
Lifts, the veneer that rotary-cut goes out tears because of external force, therefore, Veneer quality is poor, and timber utilization rate is low.
In order to solve the above-mentioned technical problem, the applicant has applied for the patent No. on 27th in August in 2008 to Patent Office of the People's Republic of China
It is 200820027355X, patent name is the patent of invention of device for preventing bending of numerical control hydraulic double-chucking shaft rotary cutter, is using process
In, the substantive deficiency of this structure is：One is during rotary-cut, because upper anti-roller and lower anti-roller are in reel
Heart surface carries out auxiliary pressing, it is difficult to control the radial run-out of reel；Two is bend preventing device complex structure, also, is pressed against wood
Pressure during core is difficult to calculate accurately, when pressure be less than reel rotary course in centrifugal force when, reel center will from
It is raised in the presence of mental and physical efforts, cause Veneer Cutting plate face gage distortion, Veneer quality is poor, or disconnected plate phenomenon is serious, works as pressure
During more than centrifugal force in reel rotary course, reel center will be pressed, and can similarly cause Veneer Cutting of poor quality, or
Disconnected plate.
