HD50/HD30 assisted paper mill to develop a new production line
Recently, the high-efficiency laminating machine developed by a company in Wuxi, Jiangsu Province was successfully applied to Dongguan Lee & Man ꦇChemical Limited, and the inverters in the core control part of th𒀰e laminating machine were all selected from Hpmont.
The new production line of Lee & Man Paper Mill i🐓s for the lamination of kraft paper, thereby reducing production costs and improving efficiency. Previously, the finished kra🦂ft paper was processed out for lamination.
The selection of inverters by Lee & Man Paper Mill has 🗹always been strict. All the inverters used before were imported brands. The successful application of Hpmont inverter in this company also proves the strength of Hpmont.
Application requirements:
Winding part (without tension fee🌊dba൲ck torque control)
Constant tension control, maintaining a constant tension throughout the winding𓆏 process;
Fast torque response, timely response to acceleration and deceleration comman♛ds, and constant tension;
Good winding and forming effect
High-speed and non-stop automatic roll change
Unwinding section (with tension feedback speed contr💟ol):
High-precision speed control, dynamically adjust t💎he motor speed in real time, keep the tension constant throughoutꦯ the unwinding process
Powerful PID func🌼tion, s🌸table tension pendulum throughout the winding process;
High-speed and non-stop automatic roll change
Application
The seven inverters on the core of the laminating machine are all equipped with Hpmont🤪 invert♑ers.
The host uses an 11kW HD30 inverter;
Rear traction 🔴uses a 7.5kW HD50 driver that achieves constꦚant local tension for different materials;
The laminating part uses a 55kW HD30 inverter for the extruder section;
The winding se🃏ction uses two 22kW HD50 drivers with tension-free feedback torquꦗe control;
The unwinding part uses two 22kW HD50 drivers with tension ꩵfeedback speed con💟trol;
Winding and 𝔉unwinding must realize high-speed and non-stop automatic roll change
HD50 drive tension control features
The Hepmont HD50 high-performance vector control driver has built-in powerful tension control function. The good performance and the nu𝔉ance of the ten💃sion control enable constant tension control in different applications, different materials and different control modes.
Main features
A variety of control modes, such as tension-free feedback torque control, tens💃ion feedback torque control, tension feedback speed control, constant linear velocity control, etc., can meet different needs of customers🎐;
Built-in roll diameter calculation module, which can automatically calculate the current r𒉰oll diam༒eter;
High🐽-precision PꦰID control module for precise control of the tension pendulum;
Perfect pre-drive functi🃏on, which can realize automatic rolღl change at high speed without stopping under various control modes;
A variety of multi-stage tensio𝄹n taper function, can achieve good winding for♏ming effect after adjustment;
A variety of compensation methods 🐠to achieve smooth tension control under various conditions
