Fully automatic weighing packaging machine

What is Fully automatic weighing packaging machine?

Fully automatic weighing packaging machine is a comprehensive packaging equipment that integrates automatic metering, filling, bag making, sealing, coding, and bag cutting. Through the preset program, the equipment can accurately complete the weighing and high-speed packaging of materials, and is widely used for materials such as granules, powders, flakes, blocks, such as rice, seeds, feed, washing powder, candy, seasonings, fertilizers, plastic granules, etc. The equipment consists of a material conveying system, a weighing system, a packaging host, a control system, and a finished product output system. It runs stably and is intelligently operated. Common models include WPM-500 (for 50g–500g), WPM-1000 (200g–1kg), WPM-5000 (1–5kg), etc., with a production range of 20 bags to 60 bags per minute. The price varies depending on the model and configuration, generally between USD $4,000–$15,000, and is suitable for the automated packaging upgrade needs of small and medium-sized enterprises to large production lines.

Working principle of Fully automatic weighing packaging machine

The core of Fully automatic weighing packaging machine lies in the deep integration of dynamic weighing and automated packaging. The workflow starts with the weighing system. The material enters the weighing hopper through the conveying equipment. The imported sensor measures the weight in real time and transmits the data to the PLC system. When approaching the preset weight, the system feeds slowly to reduce the error, with an accuracy of ±0.2%. After weighing, the material falls into the packaging container and then seals (supports hot, cold, and ultrasonic sealing). Finished products are output through the conveyor belt, and after metal detection and weight re-inspection, unqualified products are automatically rejected.

Structure of Fully automatic weighing packaging machine

Fully automatic weighing packaging machine adopts modular architecture, which consists of feeding unit, weighing unit, packaging execution unit, control system, auxiliary module and other components.

The feeding unit is composed of a screw conveyor or vibrating feeder driven by a servo motor, which can be frequency-controlled; for example, the automatic weighing packaging machine for powders adopts a double-screw feeding mode. The weighing unit is based on a high-precision weighing sensor and a dynamic compensation algorithm module, and some models have multi-head combination weighers. The packaging execution unit integrates a variety of devices, such as the pneumatic bag clamp of the fully automatic bagging packaging machine, which can adapt to the bag opening. The control system adopts Mitsubishi or Siemens controller and supports multiple languages. Auxiliary modules include dust removal, visual inspection and data acquisition terminals.

Advantages of Fully automatic weighing packaging machine

The efficiency advantage of Fully automatic weighing packaging machine is significant. Taking hourly production capacity as an example, a single device can complete 300-1200 bags of packaging, which is 3-5 times higher than that of semi-automatic models. In the chemical industry, after a company introduced a fully automatic ton bag packaging machine, the daily production capacity of a single line increased from 20 tons to 80 tons, and the labor cost was reduced by 75%. Cost optimization is reflected in three aspects:

Direct cost savings: The equipment supports 24-hour continuous operation and reduces manual intervention. For example, food companies save 2-3 operators on each production line through the automatic bagging function, saving more than 500,000 yuan in labor costs annually.

Reduced quality costs: The high-precision weighing system controls the product overweight rate within 0.5% to avoid waste of raw materials.

Implicit benefit improvement: The equipment integrates data traceability function, which can record the packaging time, weight, operator and other information of each batch, providing a basis for quality control. In addition, the modular design facilitates rapid changeover. A hardware company replaces the feeding components to achieve mixed loading of screws and gaskets, and the equipment utilization rate is increased by 40%.
