Automatic Packaging Machine with Weighing Structure

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.

What are the types of automatic packaging machines with weighing?

Automatic packaging machines with weighing can be categorized into two main types based on their structural design: vertical and horizontal. Vertical models save space and are suitable for small packages, high-speed processing, and materials with good flowability. Horizontal machines can handle complex shapes (such as bottles and large bags) and are suitable for integration into back-end production lines.

Vertical automatic weighing and packaging machines typically occupy a small footprint and are suitable for materials with good flowability, such as granules, powders, and liquids. They use a top-down filling process.

Vertical screw weighing and packaging machines are suitable for materials such as powders (such as milk powder and seasonings) and fine particles (such as sugar and coffee powder). They use the rotation of the screw to achieve quantitative filling, resulting in high accuracy and are particularly suitable for materials prone to dust emission.

Vertical gravity weighing and packaging machines are primarily suitable for granules with good flowability (such as rice and seeds) and flakes (such as potato chips). They rely on the material's own weight to drop, offering high speed and a simple structure.

Vertical liquid weighing and packaging machines are suitable for liquid or paste materials such as sauces, oils, and detergents. They are equipped with flow valves or pump control systems and feature anti-drip designs.

Vertical multi-head weighing and packaging machines are suitable for materials with irregular granules (such as snacks and frozen foods). It utilizes multiple weighing heads for combined calculations, achieving extremely high accuracy and rapid packaging efficiency.

Horizontal automatic weighing and packaging machines typically have long conveyor belts and are suitable for products requiring horizontal filling, such as bulk, bagged, and bottled items.

Horizontal weighing and filling packaging machines are suitable for bulk foods (such as bread and meat) and pre-packaged items (such as puffed foods). They utilize a weigh-before-filling process and are compatible with a variety of bag types, including pillow bags and four-side-seal bags, to meet diverse packaging needs.

Horizontal liquid filling and weighing machines are primarily used for filling and weighing bottled beverages and barreled liquids (such as mineral water and cooking oil). They utilize flow meters or load cells for precise measurement and can be integrated with processes such as capping and labeling to improve production efficiency.

Horizontal combination weighing and packaging lines are suitable for products requiring multi-station processing, such as vegetables and seafood. They integrate weighing, sorting, and packaging, adapting to the needs of automated production lines and achieving efficient and accurate packaging.

Horizontal stretch film weighing and packaging machines are primarily used for weighing and packaging boxed and palletized goods (such as parcels). After weighing, they automatically apply film, facilitating logistics and warehousing processes while protecting goods from damage.

Automatic Packaging Machine with Weighing Price

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.

Automatic Packaging Machine with Weighing Industrial Process

The industrial process of an automatic packaging machine with weighing can generally be divided into the following main stages. Each stage may vary slightly depending on the industry, such as food, chemical, or hardware, and the specific model, but the core steps are similar:

Material Supply: Materials are transported from upstream equipment (such as mixers and grinders) to the packaging machine's storage silo via a vibrating feeder, screw conveyor, belt conveyor, or gravity feed system. The silo is equipped with a level sensor to ensure a continuous supply of material and prevent material shortages or overflows.

Weighing and Metering: The core equipment is a high-precision load cell (such as a strain gauge or electromagnetic force compensation type), operating in two modes: net and gross. Net weighing involves weighing the material directly in the weighing hopper, stopping feeding when the target value is reached; gross weighing involves weighing both the material and the packaging container (such as a bag or can). Accuracy typically reaches ±0.1% to ±0.5%. High-speed machines utilize multi-head combination weighers (such as 14-head computer combination weighers) to improve efficiency.

Packaging (flexible packaging only): Bag-making machines utilize roll film (such as PE/PP composite film) folded into bags by a former and heat-sealed at the bottom. Pre-made bagging machines use a robotic arm to grasp and open pre-made bags (such as paper or aluminum foil bags).

Filling: Various filling methods are available, including gravity feeding for granules and powders (such as rice and milk powder); spiral filling for viscous materials (such as sauces and oils); and vibration-assisted filling for easily agglomerated materials (such as sugar and additives). They also feature dust-proof designs and are equipped with vacuum ports or nitrogen flushing systems (e.g., in the pharmaceutical and lithium battery material sectors).

Sealing: Heat-sealing technology is suitable for plastic films, with temperature control to prevent burn-through. Woven bags (e.g., fertilizer) are sewn using industrial sewing machines. Metal cans (e.g., paint) require crimping and are sealed using crimping technology. Additional features such as nitrogen filling for freshness preservation and vacuum sealing are also available (e.g., for coffee and meat packaging).

Labeling and Coding: Information such as the production date, batch number, and barcode are added using an inkjet printer or labeler, with vision systems verifying label placement and content accuracy.

Product Output: Packages are transported to the next station (e.g., case packer or palletizer) via a conveyor belt, roller line, or robotic arm. A rejection system is also included to automatically reject packages that fail weight requirements or have incorrect labels.
