In the length of resistance arm 311, then the active force on power arm 310 is greater than the active force on resistance arm 311, thus can
Enough reduce resistance when lift actuator 1 drives 31 ascending motion of lever.
The interior angle angle that elevating lever 30 and lever 31 are flexibly connected in its natural state is 100 °~120 °, can increase thick stick
Activity space between bar 31 and elevating lever 30, then the section that lever 31 is swung becomes larger relatively, so as to make the lifting of pressboard 2
Height section becomes larger, and can be suitable for the larger paper of thickness drop and push away.
The outside of 31 power arm 310 of lever is equipped with spring 5, and one end of spring 5 is fixedly connected on workbench, and lifting is driven
Dynamic device 1 can inevitably bring certain vibration when driving 31 lifting and swinging of lever, spring 5 can eliminate shaking when lever 31 is swung
It is dynamic, ensure that the swing of lever 31 is more stablized.
Acrylic board 6 is installed, the body structure surface of acrylic board 6 is smooth, contacts paper in the platen plane of pressboard 2
Paper will not be worn, and the pressing effect of paper is more preferable when opening platen, the wear extent for a long time using rear own material is few, makes
With longer life expectancy, anti-impact force is strong, and often in compression environment when will not deform.
Lift actuator 1 is hydraulic cylinder, and the opposite side of lever 31 is movably connected on the piston rod of hydraulic cylinder, piston rod
Lever 31 is driven during rising, and around fulcrum ascending motion, electromagnetic valve device 4 connects hydraulic cylinder oil pocket, and hydraulic cylinder bears service load
Power is big, anti-Pi Laolao intensity and impact resistance, has the extraordinary working life of operation 6000 hours, elevating movement is steady, will not
The vibration and dislocation of making mistakes property.
