MW-STB2000 （Three motor）automatic high speed slitting machine

Basic parameter

Function description

Unwinding part

＞Unwinding method:The material roll adopts a shaftless cone top head. Feeding width can be adjusted by unwinding width motor.Adopting hydraulic method to swing mechanism up and down can reach automatic roll-up and reduce labour intensity.

＞Unwinding correction:The machine uses analog correction system to track material edges or printing lines.

＞Deviation adjustment device:The unwinding aluminum guide roller has a longitudinal deviation adjustment device, allowing the material to run parallel to the guide roller to the maximum extent and ensuring rewinding precision and quality.

＞Unwinding tention detection :Two tension sensors cooperate with two pneumatic brakes to realize unwinding tension. By tension sensors, we can calculate output torque and make the material film produce a certain tension so that ensure the tension of the material film.

＞Unwinding control:。The machine has functions of starting, stopping, speed regulation, unwinding residual material reminding, unwinding tension adjustment and so on, synchronizing with the rewinding. Host can display speed and unwinding tension.

＞Unwinding receiving table:This machine is designed with a humanized inclined plane air pressure receiving platform device to facilitate quick docking of materials when changing rolls and improve efficiency.

Traction device

＞Traction drive:The traction roller is independently driven by an asynchronous high-precision servo motor.Circle-arc tooth keeps pace with belt wheel to transmit torque. The characteristic is that transmission noise is small during circle-arc tooth keeps pace with belt wheel, the transmission torque is large and power loss is small.

＞Traction roller:The traction roller has undergone dynamic and static balance correction,operates stably, has no vibration source and is suitable for a wider range of materials and high-speed applications.

＞Traction press roller:Traction press roller is made of rubber roller, which has undergone dynamic and static balance correction. The rise and fall of  traction press roller is  pneumatic control and pressure is adjustable.

＞Count meter：The motor encoder is used to detect the working length, which has the advantages of high precision and high resolution.Considering the requirement of production and craft, the program is designed with functions such as cumulative meter counting and automatic shutdown when the number is reached.

Slitting device

＞Slitting method:Round knife is used to slit.

＞Knife rest quantity: The standard number of knife rest for round knife is 30 pieces.

＞Transition guide roller:Transition drive aluminum roller has a diamond-shaped cross line on the surface,which makes the material more smooth during high-speed operation.

Waste device

＞Scrap disposal:The waste separation method of this machine adopts the suction form. When scrap is separated from the slitting knife,the guide wheel separates scrap from inside of machine to outside. And position of scrap will be on right side of machine.

Rewinding device

＞Rewinding method:3 inch  air expansion shaft achieves automatic control of tension.

＞Rewinding drive:The rewinding is driven by an asynchronous high-precision variable frequency motor.Circle-arc tooth keeps pace with belt wheel to transmit torque. The characteristic is that the transmission noise is small during circle-arc tooth keeps pace with belt wheel, transmission torque is large and power loss is small.

＞Back press roller:It’s controlled by air cylinder when contacting press roller in rewinding.The pressure is controlled by a precision pressure regulating valve. The contact press roller is rubber roller structure,can adjust air pressure according to rewinding requirement.The length of the press roller is 2000MM.

Electrical and pneumatic device

＞Drive：The drive part adopts a high-performance asynchronous servo motor drive,combined with variable frequency controller to achieve high-precision speed.

＞Control：Host is controlled by PLC program. Human-computer Interface sets operating parameter and monitors operating status.

＞Interface：Touch screen human-computer interface  is used.

＞Line layout:All circuits and gas paths of this machine adopt closed arrangemen to reduce the faults caused by human factors.

＞Pneumatic components:This machine has more automatic control in terms of functions, so it is more comprehensive in the selection and design of pneumatic components.The electrical components of the whole machine are all famous brands at home and abroad.

Other configuration

＞This machine uses high-strength, low-stress steel wall panels with a thickness of 50mm.Wall panel is relieved of secondary stress and has good stability.

＞All rotating parts of this machine adopt bearings imported from Japan.

＞The mechanical parts of this machine are all processed by machining center and numerically-controlled machine tool.

＞Emergency stop buttons and emergency pull-wire switches are installed in the operation of the machine.
