Automatic Packaging Machine With Weighing

What is an Automatic Packaging Machine with Weighing?

Automatic Packaging Machine With Weighing is a system that measures material mass and completes the packaging process. It uses sensors to monitor weight data in real-time, coordinated by PLC or microprocessor units. This equipment performs filling, sealing, and coding. It works with various product forms, including granules, powders, and liquids.The weighing range for this equipment typically spans from 5g to 5kg or 10kg to 50kg, with a margin of error between $\pm0.1\%$ and $\pm1\%$. It maintains uniform weight across bags. The system compatible with materials such as composite film, PE film, and aluminum foil. It supports bag types like stand-up pouches, back-seal bags, and 3-side seal bags.Operation speeds vary based on material properties and bag types. Standard models reach 20 to 120 bags per minute, while high-speed versions exceed 200 bags per minute. The sequence includes feeding, weighing, bag clamping, and sealing. This mechanical process replaces manual labor in industrial production lines.

Types of Automatic Packaging Machine With Weighing

Automatic weighing and packaging equipment is categorized into vertical and horizontal configurations based on mechanical structure. Vertical models require less floor space and process small-format packaging for materials with high flowability. Horizontal models handle complex shapes, such as bottles and large bags, facilitating integration into end-of-line production systems.

Vertical Automatic Weighing Packaging Machines

Classification based on material properties includes the following:

Auger Weighing Models: Used for powders or fine granules like coffee. These units employ screw rotation for quantitative filling, suitable for dust-prone environments.

Gravity Weighing Models: These rely on the mass of the material for measurement. This design suits granules or flakes with consistent flow, such as rice, seeds, and chips.

Liquid Weighing Models: Configured for liquids or pastes like sauces and oils. These systems use flow valves or pump controls with anti-drip components to manage cleanliness.

Multi-head Weighing Models: Applied to irregular granules, including frozen foods. This type uses multiple weighing buckets for combined measurement to achieve set mass targets.

Horizontal Automatic Weighing Packaging Machines

Horizontal systems are applied to products requiring lateral filling into bags or containers. Long conveyor belts facilitate the positioning of various packaging types.

Horizontal Weighing and Filling Machines: These follow a "weigh-then-fill" sequence, compatible with pillow bags and 4-side seal bags for items like bread or meat.

Horizontal Liquid Filling Units: These use flow meters or load cells to measure volumes for bottled beverages or drummed oils, connecting with capping and labeling processes.

Combined Horizontal Lines: These integrate weighing, sorting, and packaging for multi-stage processing of vegetables and seafood.

Stretch Film Weighing Systems: Used for boxed or tray-loaded goods. The system wraps film after weight verification to assist in logistics and storage.

How much does Automatic Packaging Machine with Weighing cost?

The following approximate price range for Automatic Packaging Machine with Weighing is for reference: Basic semi-automatic machines range from $2,000 to $7,000, suitable for small and medium-sized production operations. They require manual loading and typically have a weighing accuracy of ±1-5g. Fully automatic mid-range models range from $7,000 to $10,000, offering automatic weighing accuracy of ±0.1-1g and a relatively fast packaging speed of 20-60 packages/minute. They are suitable for industries such as food and chemicals. High-end intelligent production lines range from $10,000 to $15,000, featuring high accuracy of ±0.01g and a speed of 100+ packages/minute. They also feature integrated PLC control and data traceability, making them suitable for large-scale production.

What are the applications of Automatic Packaging Machine with Weighing?

Automatic Packaging Machine with Weighing plays a key role in various industries. In the food industry, it's used for rapid packaging of products such as rice, sugar, nuts, dried fruit, and biscuits. In the chemical industry, it's suitable for accurately measuring materials such as additives, granular fertilizers, calcium carbonate, and resin powder. In the feed and agricultural product processing sector, it can efficiently weigh and package feed pellets, livestock premixes, grains, and seeds. In the pharmaceutical industry, some models can also be used to automatically seal small packages of materials such as herbal granules and solid beverages.

How does Automatic Packaging Machine With Weighing work?

The Automatic Packaging Machine with Weighing operates as follows: After products enter the machine via a conveyor belt or hopper, a high-precision load cell monitors their weight in real time. The system then controls dual-speed feeding based on preset values: a fast coarse feed and a slow fine feed to ensure accuracy. When the weight reaches the target, the material door automatically closes, completing dynamic weighing. The product is then filled into pre-positioned bags, and sealing and coding processes are completed simultaneously. The entire process is coordinated by a PLC control system.

What are the structural components of Automatic Packaging Machine with Weighing?

Automatic packaging machines with weighing consist of several key components: a feeding system equipped with a hopper, vibrating feeder, or screw feeder, which evenly conveys materials to a weighing unit; a weighing system employing electronic load cells and a control module for high-precision weighing; a packaging system using a bag-making machine or pre-made bag clamping mechanism to pack the weighed materials into bags; a sealing device using heat or cold seals to ensure a tight seal; a conveyor system using conveyor belts or turntables to transport bags between process steps; a control system using a PLC and touch screen for automated control, parameter setting, and data logging; and a frame and protective devices to support various components and ensure safe operation.

Automatic Packaging Machine with Weighing Industrial Process

The Industrial Process of an Automatic Packaging Machine With Weighing involves a series of technical stages. Initially, Material Supply units, such as screw or belt conveyors, transport substances from mixers to a storage hopper monitored by level sensors. During Weighing and Measurement, load cells using strain gauge technology calculate the mass in net or gross weight modes, maintaining accuracy between $\pm0.1\%$ and $\pm0.5\%$. For flexible packaging, the Bag Forming system utilizes film rolls or mechanical arms for premade pouches. The Filling stage employs gravity, auger, or vibratory methods depending on material flow, often incorporating nitrogen flushing. Sealing is performed via thermal bars for plastic films or industrial sewing for woven bags. Finally, Coding and Labeling units apply batch data, verified by vision systems, before the Product Output phase where conveyors move finished units to palletizing stations while rejection systems remove non-compliant packages.
