Why does the aluminum foil slitting machine adopt the upper and lower center surface winding?

What is an aluminum foil slitter?

According to the material, the slitter is divided into: film slitter, paper slitter, cloth slitter, leather slitter, copper and aluminum foil slitter, etc. Aluminum foil slitting machine is one of the material slitting machines, usually the most suitable for slitting thin paper, copper foil, aluminum foil, PVDC, breathable film.

Slitting machine is a kind of mechanical equipment that cuts wide paper, mica tape or film into multiple narrow-width 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. The slitting machine has a horizontal slitting machine and a vertical slitting machine, and the vertical slitting machine is faster than the horizontal slitting machine.

How does the aluminum foil slitter cut aluminum foil?

Aluminum foil needs to be slit on the slitting machine. Cut the semi-finished product in large rolls into the required specifications. The semi-finished product that is cut on the slitting machine is a process of unwinding and rewinding. This process includes the running speed control and tension control.

The so-called tension means that in order to pull the aluminum foil and wind it on the core according to the standard, a certain stretching and tensioning traction 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 emergency stop situations, it has the ability to guarantee that the aluminum foil will not be damaged in the slightest.

Slitting machine tension control is basically divided into manual tension control and automatic tension control.

Manual tension control means that during the winding or unwinding process, when the roll diameter changes to a certain stage, the operator adjusts the manual power supply device, so as to achieve the purpose of tension control.

Fully 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. By comparing this signal with the preset tension value of the controller, the control signal is calculated. The execution unit is automatically controlled to make the actual tension value equal to the preset tension value, so as to achieve the purpose of stabilizing the tension.

Automatic aluminum foil slitter

The setting of winding and unwinding tension of the equipment directly affects the yield of the product. If the tension is too high, the winding is too tight, and the aluminum foil is prone to wrinkles; If the tension is too small, it will cause a large swing between layers of aluminum foil on the unwinding shaft during slitting, which will affect the quality of slitting. So the slitting machine must have a good tension detection system.

To sum up, the aluminum foil slitting machine adopts the active winding method of the winding shaft, and the winding machine is divided into upper winding and lower winding to complete the winding of double-fold aluminum foil respectively, so that some aluminum foils will not be scratched. , making the material scrapped. Aluminum foil slitting machine is the finishing equipment in aluminum foil processing. In the global development of "finishing" equipment, it can be regarded as high-end and high-precision modern equipment. Since the aluminum foil slitter is an important post-process of aluminum foil production and has an important impact on the quality and yield of aluminum foil, the aluminum foil slitter is a must and key technical equipment for modern aluminum processing enterprises.
