Unwinder press arm device, Shanghai building material stamping
processing, Ruihui automatic feeder
Performance advantages of heavy material frame press arm device:
1. When the heavy material frame press arm is actuated, the
extension arm of the telescopic cylinder directly actuates the
pressure arm frame, which is directly actuated, which can reduce
the loss of its power, so its force is large.
2. The structural design of the heavy material frame press arm is directly locked on the frame without being restricted
by space, so the output angle is large, so the press arm frame is
not easy to shake.
3. The heavy-duty material frame press arm uses the telescopic
cylinder to directly actuate the pressure arm frame, without the
need to transmit through the other functions such as the key block,
so the strength of the transmission structure is better, and no
loose damage occurs.
4. The pressure roller can adjust the position by using the
adjusting bolt of the ring frame to ensure that the pressure roller
and the material roll can be flat to avoid the plate from being
misaligned during feeding.
