The Best Plan for Paperboard Production--Three Elements of Paperboard Quality" (4)

For pneumatic brakes, the two pressure regulators on the air control cabinet must be adjusted for optimum tension. The pressure measured by the two sides of the paper is not necessarily equal, and it is generally adjusted between 0.055 Mpa and 0.4 Mpa. The tension of the paper roll also changes. The larger the paper roll, the tighter the brake. The smaller the brake, the looser. It is forbidden to cast oil on the brake block.

The operating switch box on the arm of the support arm is operated, and the clamping, releasing, moving left, right, and descending of the stand are controlled by the hydraulic pressure.

1) When the paper roll is set, press the ascending switch first to raise the arm, and then press the release switch to separate the arms. When the upper paper cart conveys the paper roll into place, press the lower switch to drop the arm (Note: Do not touch the paper roll on the top so as not to damage the machine and crush the paper roll). Make the top pair; pick the roller core hole, press the clamping switch, clamp the paper roller (clamping force can not be too large, need to clamp and then jog to relax the switch to prevent damage to the arm);

2) Adjust the brake on the arm to adjust the tension. For manual braking, the handle can be rotated to adjust the tightness of the brake, that is, adjust the tension.

For pneumatic brakes, two pressure regulators on the air control cabinet must be adjusted for optimum tension. The pressure measured by the paper edge is not necessarily the same, and it is generally adjusted between 0.05 MPa and 0.4 MPa. The tension of the paper roll also changes. The larger the paper roll, the tighter the brake. The smaller the brake, the looser. It is forbidden to cast oil on the brake block.
