Application of frequency converter in cosmetics assembly line

The cosmetics assembly line dedicated frequency converter is a high-performance electrical energy control equipment developed specifically for the cosmetics production industry. It achieves automation, flexibility, and efficiency in the production process by intelligently adjusting the motor speed, torque, and power output, accurately matching the process requirements of various links in cosmetics production (such as mixing, filling, sealing, packaging, etc.). This frequency converter adopts industrial grade design, with strong anti-interference ability, adaptability to harsh environments, and long-term stable operation. It is an ideal choice for cosmetics enterprises to improve production efficiency, reduce energy consumption, and ensure product quality.

Mixing process

Demand: cosmetics raw materials (such as lotion and cream) should be mixed evenly to avoid caking or layering.
Function of frequency converter: Through vector control, it achieves low-speed and high torque output, accurately adjusts the speed of the mixing motor, adapts to the mixing needs of different viscosity raw materials, and ensures stable product quality.

Filling process

Requirement: The filling speed should be synchronized with the rhythm of bottle conveying to prevent liquid splashing or insufficient filling.

Function of frequency converter: In conjunction with PID closed-loop control, it adjusts the filling pump speed in real time to achieve high-speed and precise filling, improve production efficiency, and reduce raw material waste.

Sealing/capping process

Requirement: The sealing machine or capping machine needs to operate stably to avoid loose sealing or damaged lids.
Function of frequency converter: Control the operating speed of equipment through speed regulation function, ensure uniform sealing force, and improve product qualification rate.

Labeling/packaging process

Requirement: The labeling machine and packing machine need to operate synchronously with the production line to avoid material accumulation or interruption.

Function of frequency converter: Adjust the speed of the conveyor belt, achieve overall coordinated operation of the production line, and improve packaging efficiency.

Conveyor line control

Requirement: The conveyor belt needs to dynamically adjust its speed according to the production rhythm to avoid material congestion or idling.

Function of frequency converter: By synchronously controlling multiple motors, it ensures stable operation of the conveyor line and reduces manual intervention.

Efficient and energy-saving, reducing operating costs

Soft start function: reduces the starting current of the motor, avoids impact on the power grid, and extends the service life of the equipment.
Speed regulation and energy saving: dynamically adjust the motor speed according to the load demand to reduce energy consumption. For example, after adopting variable frequency speed regulation, the energy-saving rate of fans and pumps can reach 20% to 60%.
Regenerative braking: Recovering energy during deceleration or shutdown to further save electrical energy.

Stable and reliable, adaptable to harsh environments

Industrial grade design: with a protection level of IP55 or above, dustproof and waterproof, suitable for humid and dusty environments in cosmetics production workshops.
Strong anti-interference ability: adopting EMC filtering design, effectively suppressing electromagnetic interference and ensuring stable operation of the equipment.
Multiple protection functions: including overcurrent, overvoltage, undervoltage, overheating, short circuit, etc., to prevent equipment damage and reduce the risk of shutdown.

Precise control to improve product quality

Multi control modes: support V/F control, vector control (SVC/FVC), PID closed-loop control, etc., to meet different process requirements.
High speed response capability: response time ≤ 10ms, suitable for the process requirements of rapid switching in cosmetics production.
Modular design: facilitates quick replacement of faulty modules, shortens maintenance time, and reduces downtime losses.

Taking the transformation of a 20 meter automatic cutting production line in a cosmetics manufacturing enterprise as an example:

• • Before the renovation, traditional speed regulation methods were used, which resulted in high starting current of the equipment, severe impact on the power grid, and inflexible speed regulation, leading to low production efficiency.
  • After renovation: Mitsubishi frequency converter and PLC control system are introduced to achieve the following optimizations:

High speed/low-speed control of the feeding motor: automatically adjust the conveying speed according to the specifications of the iron plate, saving time.
Dynamic adjustment of ruler position: By using the front ruler solenoid valve and the moving motor, the cutting position is precisely controlled to improve the product qualification rate.
Significant energy-saving effect: After the renovation, the energy consumption of the equipment decreased by 20%, and the production efficiency increased by 15%.
Stability enhancement: The frequency converter has multiple protection functions to reduce equipment failures, and has operated for one year without major shutdown accidents.
