Working principle and matching device of uncoiler
2024.08.22
Uncoiling machine is a kind of machine equipment for winding or unwinding sheet metal, its working principle is through the motor to drive the expansion drum rotation, control the curling or unwinding degree of sheet metal, so as to achieve the function of winding or unwinding.
When the uncoiler actually works, the process is as follows:
1. First place the metal coil on the expansion reel of the uncoiler.
2, the unwinding machine through the motor to drive the expansion drum rotation, so that the metal sheet began to curl or unfold.
3. In the process of curling or unfolding, the unwinding machine controls the curling or unfolding degree of the metal sheet by adjusting the speed and tension of the expanding drum.
4. When the metal sheet is curled or unfolded to the required length, the unwinding machine will contact the induction frame, thus stopping the operation and completing the work of winding or unfolding.
The optional devices of the uncoiler include frequency converter, press arm, photoelectric protection device, hydraulic expansion, loading trolley, film receiving device, etc. The functions of the optional device are as follows:
1, the frequency converter is used to adjust the discharge speed, so that the discharge or receipt of materials is more stable;
2, the press arm is used to press the outer edge of the material to avoid the loose material problem when the material thickness exceeds 2.0mm;
3. The photoelectric protection device is used to replace the traditional contact sensor frame, which can control the start and stop of the uncoiler without touching the material;
4, hydraulic expansion is used to replace the traditional hand expansion, so that the material roll can be tensioned when more than 2 tons;
5, the loading trolley is used to assist the loading, reduce the downtime refuelling time;
6. The film receiving device is used to collect the film or paper tape on the outer surface of the roll material.
