Step 2：Control unit control is stirred motor 8 and is rotated with the speed of 120-140r/min, and makes Shifting rack 6 with 1.1-
The speed of 1.3cm/s is close to along guide rail 7 is stirred to clamping joint 3；Meanwhile, control unit controls the velocity of rotation of power transmission shaft 1 with 100-
The speed of 110r/min drops to 200-230 r/min；
Step 3：After 4s, control unit control control Shifting rack 6 is stirred guide rail 7 and is leaned on to clamping joint 3 with the speed edge of 5-5.5m/s
Closely, clamping tooth is made to coordinate clamping with clamping joint 3, meanwhile, when the pressure value of control unit detection pressure sensor is higher than 200pa,
Motor 8 is stirred in closing；
Step 4：The control unit control velocity of rotation of power transmission shaft 1 rises to 550-600 r/ with the speed of 180-190r/min
min；
Step 5：When need eccentric wheel 2 depart from when, control unit control power transmission shaft 1 turn with the speed of 100-110r/min
It is down to 200-230 r/min；
Step 6：Control unit control control Shifting rack 6 stirs guide rail 7 away from clamping joint 3 with the speed edge of 10-12m/s；
Step 7：After 0.2s, control unit controls Shifting rack 6 to stir guide rail 7 away from clamping joint with the speed edge of 0.3-0.5cm/s
3；Meanwhile, the rotating speed of control unit control power transmission shaft 1 rises to setting value with the speed of 50-80r/min；
Step 8：Deflecting wheel edge is stirred guide rail 7 and is moved at contact-making switch away from clamping joint 3, deflecting wheel is reached apart from clamping joint
Motor 8 is stirred in the initial position of 35-10cm, closing.
The above method can realize that the working condition of eccentric wheel 2 is accessed and exited, and improve the continuity of vibrator, effectively protect
The normal work effect of card equipment, the quick vibratory output for changing vibrator, it is ensured that equipment is strong in the design of the structure of Common Steels
Under degree, most fast add eccentric wheel 2 runs and adjusts vibratory output, it is to avoid the excessive destruction caused to equipment of momentum in itself, leads to
Cross reduction of speed and access the mode that enters compared to non-deceleration splice, its impact to structure and the impact reduction by 80% to motor and its circuit
More than, the Based Intelligent Control and intelligence for being more beneficial for equipment are added；By the instantaneous disengaging and access of eccentric wheel 2, eccentric wheel 2 is improved
Disengaging efficiency, in the effective life-span for improving equipment, by the control to toggle mechanism, can realize that the quick of eccentric wheel 2 pushes away
Go out operation, the control eccentric 2 that is designed to of contact-making switch reaches initial position and ensure that the normal of equipment is used, it is to avoid
Other eccentric wheels 2 are impacted around eccentric wheel 2 pairs..
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Any modification, equivalent and improvement made within god and principle etc., should be included within the scope of the present invention.
