Fully automatic packaging machine

The fully automatic packaging machine is an intelligent packaging equipment that integrates automatic feeding, metering, filling, sealing, cutting, printing and conveying, and is widely used in multiple industries. Compared with traditional semi-automatic equipment, it can realize unmanned operation throughout the whole process, greatly improve production efficiency, reduce labor costs, and ensure packaging consistency and product qualification rate. The equipment is suitable for a variety of materials such as powders, granules, liquids, pastes, etc., and is compatible with a variety of packaging forms such as bags, bottles, and boxes to meet the packaging needs of different products.

 

1. How does the fully automatic packaging machine work?

The operation of the fully automatic packaging machine relies on the motor to drive the main shaft, and the transmission mechanism drives the feeding, metering, forming, filling, sealing, cutting and other modules to work together. PLC (programmable logic controller) is the core control system, which coordinates the actions of various components in real time, and cooperates with feedback devices such as photoelectric detectors and sensors to ensure packaging accuracy and continuity. For example, when the packaging film or container is detected to be in place, the equipment automatically completes the filling and sealing actions to achieve full process automation.

2. The fully automatic packaging process mainly includes the following steps:

Automatic feeding: materials enter the metering unit through conveying equipment (such as screw feeder, vibrating hopper);

Precise metering: automatic measurement of material weight or volume according to set parameters;

Forming and positioning: the packaging film is made into a bag shape or aligned with the packaging container by a former or positioning system;

Filling material: the material is filled into the package according to the set amount;

Sealing and cutting: heat sealing or cold sealing technology is used for sealing, and cutting or coding according to size;

Finished product transportation: after packaging is completed, it is automatically transported to the next process or packing area.

This process is fully automatic and efficient, especially suitable for large-scale and continuous production scenarios.

3. Technical parameter reference

The main technical parameters of the fully automatic packaging machine vary according to its purpose and structure:

Packaging speed: 30-100 bags/minute (high-end can reach 200 bags/minute);

Measuring accuracy: ±0.2-1.0g, depending on the material and system;

Bag size: 50-300mm long, 40-200mm wide (customizable);

Power supply and power: AC220V/380V, power 1.5-5kW;

Air source requirements: pressure 0.4-0.8MPa, consumption about 200-500L/min;

Applicable materials: composite film, aluminum foil, paper-plastic film, stretch film, etc.

Users can select the model according to actual needs to ensure the balance between efficiency and cost.

4. The role of PLC in packaging machine

PLC plays the role of "central nervous system" in automatic packaging machine, responsible for the logical judgment, operation control and safety protection of the overall process. Common brands include Siemens, Mitsubishi, Omron, Delta, etc. High-end equipment is often equipped with models such as Siemens S7-1200 and Mitsubishi FX, which support high-speed data processing, rich I/O interfaces, touch screen HMI and communication expansion, and can be linked with servo systems, weighing modules, and visual systems to ensure that the packaging process is accurate, efficient, and stable. PLC performance directly affects the response speed and control accuracy of the equipment, and is one of the core elements to ensure equipment performance.

Fully automatic packaging machines have become an indispensable key equipment for modern industrial packaging due to their high efficiency, precise control and intelligence. It not only improves the level of production automation, but also ensures the beauty and consistency of product packaging. Through flexible technical parameter settings and high-performance PLC system integration, the equipment can adapt to diverse material and packaging needs.
