Description
Technical field
The present invention relates to pulp and paper technology field, more particularly to the high-speed shaking case apparatus and amplitude of a kind of adjustable amplitude
Adjusting method.
Background technology
It is to cause the undesirable principal element of formation of sheet, and aligning for fourdrinier part fiber results in paper that fleeces is poly-
Aspect ratio and lateral shrinkage it is high, in wet end shake system, speed difference is generated with lower layer on the upper layer of slurry stream, carry out shearing and
Disturbance can effectively overcome fleeces poly-, alleviate aligning for fiber, improve the aspect ratio of evenness and paper.Common wet end
Shake system transmits vibrations to forming table by shaking box, and slurry is driven to generate vibration in the lateral of paper machine.But its vibration
Frequency and amplitude are all limited, centering, high-speed paper machine effect unobvious.But also vibration is generated in vertical direction, draw when serious
Take-off is starched.Mechanical wear is accelerated, and the fracture of rack, steel spring plate etc., even basic damage are easily caused.
In order to adapt to the requirement of middle and high fast paper machine, papermaker has researched and developed high-speed shaking box.High-speed shaking box is pressed
Physics centre-of-gravity principle works, and using several part mass moved in same system, the center of gravity for keeping its common is constant；Same
In gear mechanism housing, the arrangement of quality is to make center of gravity that can only be moved along breast roll axis direction, if vibrator quality turns
It is dynamic, then breast roll with a counter motion in response.Inertia force in kinematic system remains unchanged, and is only passed by shake bar
It passs.To reach the vibration frequency and amplitude that common vibrator is unable to reach.
Four pairs of gears and four eccentric blocks are installed, amplitude Principles of Regulation are to adjust the phase of two pairs of eccentric blocks in shaking box
Parallactic angle achievees the purpose that adjust shake amplitude so as to adjust the size of shake power produced by shaking box.
The mode of existing high-speed shaking box adjusting amplitude is divided into two kinds, and one is use two servo motors and a set of servo
Control system, each servo motor are connected with the driving gear in two pairs of gears, independent control and the position for adjusting each pair of eccentric block
It sets.Another kind is to use a servo motor, and two transmission shafts, two transmission shafts are connected with the driving gear of shaking box.Servo
Motor is connected with a transmission shaft therein, is connected again by comparing complicated geared system between two transmission shafts,
All there is respective deficiency in both above-mentioned control modes, in first way, mechanical structure is relatively easy, but
The amplitude of shaking box is adjusted to the phase angle of eccentric block in operational process stepless changing two, there are one each pair of eccentric block is intended to
Phase detector, while the phase to each pair of eccentric block being needed to control, this needs extremely complex control system, investment and
Maintenance cost is very high.Although the second way only with a servo motor, is equipped with a set of with servo motor transmission axis phase
Continued proportion more complex transmission device and amplitude regulating device.Therefore no matter which kind of mode, control system is all extremely complex, investment
It is very high with maintenance cost.
