How to Use Cosmetic Filling and Sealing Machines

Introduction

The filling and sealing system for cosmetics is a machine used for various processes, such as filling, sealing, and drying cosmetics. The system essentially consists of three parts: mechanical, electrical, and control systems. This article provides a detailed overview of the operating principle of the automatic filling and sealing system for cosmetics.

Here's How to Understand Some of the Cosmetic Filling and Sealing Equipment

Mechanical Section

The mechanical components of the automatic filling and capping machine for cosmetics include a bottle feeding section, a filling section, a capping section, a drying section, etc.
Bottle/Tube Feeding Unit
The bottle feeding section consists mainly of a conveyor belt, a bottle position detection system, a quantitative feeder, etc. The conveyor belt is driven by a motor to transport the empty bottles to the filling section at specific intervals.
Filling section
The filling unit consists mainly of a filler, an electric pneumatic valve, etc. Set the filling volume according to the requirements and fill the bottle with powder or liquid material through the filler. As soon as the bottle is inserted, the electric pneumatic valve opens and the material flows out. Once a specific fill volume is reached, the process stops automatically.
Seal component
The sealing unit consists mainly of a sealing machine and a heating element. After filling, the bottle is fed into the sealing machine for sealing. The heating unit transfers heat to the sealing section via an electric heater, heats and melts the material at the sealing section, and fuses it to the bottle’s sealing section.
Drying Section
The drying section consists mainly of a heater. After capping, the bottle is sent to the heater for drying. The heater uses electric heating to evaporate the moisture on the bottle's surface in order to dry the bottle opening.

Electrical Components

The electrical components of the automatic filling and capping machine equipment for the cosmetics filling and capping machine consist mainly of various sensors, pneumatic components, temperature controllers, motors, and PLC controls.

Control System

The control system of the automatic filling and capping machine for cosmetics consists primarily of a PLC and a human-machine interface. The PLC is responsible for controlling the entire system, while the human-machine interface is responsible for monitoring and operating the system.

How to Use Automatic Filling and Sealing Machines

The steps for using the automatic filling and capping machine for cosmetics are as follows:

• Place the material to be filled into the device's material hopper.
• Place the cosmetic bottles to be filled on the conveyor belt and set the fill volume for each bottle as needed.
• Turn on the power to the machine, start it up, and let the conveyor belt automatically transport the bottles to the filling, sealing, drying, and other stations.
• After waiting for the machine to complete all processes, remove the filled, sealed, and dried cosmetic bottles and pack them.

Graduation

The operating principle of the automatic filling and capping machine for cosmetics essentially consists of three parts: mechanical, electrical, and control systems. The system can perform multiple processes—such as filling, capping, and drying cosmetics—simultaneously, which improves automation and production efficiency in cosmetics manufacturing and reduces production costs.
