The 500 wide 7-ton uncoiler is an industrial machinery equipment used for metal coil processing, which can perform operations such as opening, leveling, and winding of coil materials. This type of uncoiler is usually suitable for leveling lines of steel plates and uneven plates, and can be used to form production lines for sheet products such as uncoiling, leveling, and cutting according to relevant configurations. The performance of the uncoiler is crucial for the smooth operation of the entire production line, especially in the welded pipe production line. The uncoiler not only needs to support the tension of the steel coil, but also needs to rotate the steel mobilization part in conjunction with the straightening machine to feed it into the straightening machine.
Working principle and functional characteristics
The working principle of the 500 wide 7-ton unwinding machine is 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 induction frame. The main shaft of the uncoiler has two functions: driving the rotation of the steel coil and supporting the tension of the steel coil. The implementation of tightening is usually achieved by using an oil cylinder or air cylinder installed on the spindle to push the inclined slider, while rotation is achieved by the motor driving the spindle through a reducer.
One of the functions of the uncoiler is to unwind the strip steel under tension while maintaining it, and another important function is to achieve automatic alignment of the strip steel under intermediate control. The traditional continuous winding and color coating unit is equipped with two uncoiler machines, which work alternately to create conditions for the continuous production of subsequent equipment in the unit.
Application industry
The 500 wide 7-ton uncoiler is widely used in industries such as machinery, vehicles, construction, home appliances, steel structures, and decoration. It is an important supporting equipment for production lines such as steel plate leveling line, embossing machine, laser cutting and cutting machine, which has a significant impact on the overall operation of the production line.
Maintenance and operation precautions
When using a 500 wide 7-ton uncoiler, regular maintenance should be carried out, such as checking the machine's fasteners and bearing seats, confirming that the screws are not loose, and operating according to the manufacturer's instruction manual. In addition, overloading of equipment should be avoided to ensure the long-term stable operation of the machine and the safety of the operators.
