The 5-ton unwinding and rewinding machine with loading trolley is an automated equipment used for metal coil materials. Its main functions include carrying and discharging materials, unfolding coils, and rewinding. These machines are widely used in the metal processing and manufacturing industry, such as stamping, laser cutting, cold bending and other production lines. The uncoiler can be divided into various types based on different material characteristics and production needs, such as heavy-duty uncoiler, hydraulic uncoiler, double head uncoiler, lightweight uncoiler, and disc horizontal uncoiler.
The working principle of the unwinding machine is usually based on the vertical expansion and contraction unwinding method. The coil material is vertically placed on the expansion and contraction drum, and after being tensioned by the drum, the motor drives the expansion and contraction drum to rotate, driving the material coil to unwind. After the material strip is uncoiled, it naturally droops and automatically stops when it comes into contact with the sensing frame. During the process of material uncoiling, when the length of the uncoiled material reaches the stamping condition, the uncoiler will automatically stop working.
Application and Operation of Uncoiler
Uncoiler is usually used in conjunction with various processing machines, such as punch presses, laser cutting machines, etc., for the feeding or winding of metal coils. Operators need to perform corresponding operations based on specific machine models and job requirements, including placing rolls, adjusting machine settings, monitoring the unwinding process, etc. When choosing an uncoiler, it is necessary to consider the width, thickness, load capacity, inner and outer diameter requirements of the metal coil material, as well as the speed of discharge and the degree of automation of the operation.
Maintenance of the unwinding machine
Regular maintenance is crucial for confirming the normal operation of the uncoiler and extending its lifespan. Maintenance work includes checking the fasteners, bearing seats, and screws of the machine for looseness, as well as regularly lubricating the spindle bearings and replacing the gearbox oil. In addition, regular maintenance and inspection should be carried out according to the manufacturer's instruction manual.
