Heavy-duty uncoiler: This unique piece of equipment is used to level steel plates and other types of uneven metal plates. Depending on the configurations necessary, it may be made up of manufacturing lines for uncoiling, leveling, shearing, and other plate products. It is appropriate for usage in a variety of sectors, including those that produce steel buildings, metal goods, home appliances, and decorating. The uncoiler’s main source of power comes from the reel shaft, which is driven by the machine’s variable-frequency speed-regulating motor after it has been decelerated by the gearbox.
The uncoiler of the welded pipe unit may prevent the unwinding of the strip after the strap of the coil is opened by avoiding the loose coil created by the unwinding of the strip during uncoiling and by adjusting the back tension provided to the strip. Before the next gadget bites the skull, the head bounces.
How to adjust the brake of heavy uncoiler
- Make sure that the brake pads are installed horizontally and the brake lever is in a vertical position.
- Tighten the adjusting bolt with a screwdriver to compress the brake pads. The brake pads should fully contact the surface of the brake bowl.
- Gradually increase the slack of the brake lever, and adjust the bolts to increase the contact area of the brake pad to ensure stable braking performance.
- Start the machine and move the side panels under normal conditions to ensure that the machine can start and run normally.
How is the tension of the heavy uncoiler controlled?
nk is the rated speed of the uncoiler; v is the linear speed of the steel strip m/min; i is the speed ratio of the traditional system; D is the diameter of the steel coil, and ne is the rated speed of the uncoiler motor r/min. The torque setting of the uncoiler is the percentage of the actual torque and the rated torque, calculated from the tension of the steel strip, as follows: In the formula, TR is the torque setting of the uncoiler, %; T is the tension of the steel strip, N ; Te is the rated torque of the decoiler motor, N m. The torque compensation of the uncoiler includes no-load torque and dynamic torque during acceleration, which can be obtained by actual measurement. It is worth mentioning that the above calculations are all related to the roll diameter, but the roll diameter is constantly changing in actual operation, so a special calculation must be used.
