What Is An Aluminum Foil Slitter?
According to the material, the slitting machine is divided into: film slitting machine, paper slitting machine, cloth slitting machine, leather slitting machine, copper and aluminum foil slitting machine, etc. Aluminum foil slitting machine is one of the material slitting machines, which is usually most suitable for the slitting of thin paper, copper foil, aluminum foil, PVDC, and breathable film.
Slitting machine is a kind of mechanical equipment that cuts wide paper, mica tape or film into multiple narrow materials. It is often used in papermaking machinery, wire and cable mica tape and printing and packaging machinery. The slitting machine we generally use can also be called a slitting machine or can be used for rewinding. There are horizontal slitting machines and vertical slitting machines, among which the vertical slitting machine is faster than the horizontal slitting machine.
How does the aluminum foil slitting machine slit the aluminum foil?
The aluminum foil needs to be cut on the slitting machine after printing, and the semi-finished products in large rolls are cut into the required specifications. There are two parts: running speed control and tension control.
The so-called tension is that in order to pull the aluminum foil and roll it to the core according to the standard, a certain stretching and tensioning force must be applied to the aluminum foil, and the tensioning force of the aluminum foil is the tension.
Tension control refers to the ability to well control the tension of the aluminum foil when it is conveyed on the equipment. This control must be effective for any running speed of the machine, including the acceleration, deceleration and uniform speed of the machine. Even in the event of an emergency stop, it has the ability to ensure that the aluminum foil is not damaged in the slightest.
The tension control of the slitting machine is basically divided into manual tension control and automatic tension control.
Manual tension control is that in the process of winding or unwinding, when the diameter of the roll changes to a certain stage, the operator adjusts the manual power supply device to achieve the purpose of controlling the tension.
The automatic tension control is to directly measure the actual tension value of the material belt by the tension sensor, and then convert the tension data into a tension signal and feed it back to the tension controller. Automatically control the execution unit to make the actual tension value equal to the preset tension value to achieve the purpose of stabilizing the tension.
The size of the tension setting of the rewinding and unwinding of the equipment directly affects the yield of the product. If the tension is too large, the rewinding is too tight, and the aluminum foil is prone to wrinkles; Unloading, and causing the unwinding shaft to swing greatly during slitting, which affects the quality of slitting, so the slitting machine must have a good tension detection system.
In summary, the aluminum foil slitting machine adopts the method of active winding by the winding shaft, and the coiler is divided into upper and lower winding, respectively, to complete the winding of the double-sided aluminum foil, so that some aluminum foils will not be scratched. , which makes the material scrapped. Aluminum foil slitting machine is a finishing equipment in aluminum foil processing. In the global development of "finishing" equipment, it can be regarded as a high-end and high-precision modern equipment. Since the aluminum foil slitting machine is an important post-process of aluminum foil production, it has an important impact on the quality and yield of the aluminum foil, so the aluminum foil slitting machine is a must and key technical equipment for modern aluminum processing enterprises.
