Automatic Packing Machine With Weighing

What is Automatic Packing Machine With Weighing?

Automatic Packing Machine With Weighing is an intelligent device that integrates metering, filling and sealing. It is suitable for quantitative packaging of granules, powders, flakes and other materials. Through high-precision weighing sensors and PLC system control, accurate weighing and fast packaging of materials are achieved. The equipment is divided into granule, powder and liquid packaging machines according to the material type, with strong adaptability. The weighing range is 0.2kg to 50kg, the accuracy is ±0.2% to ±0.5%, and the speed can reach up to 40 bags/minute. The packaging process automatically completes the feeding, weighing, bag clamping, sealing and other links, with the advantages of high efficiency, accurate precision, simple operation, stable operation, etc., which significantly improves production efficiency.

Automatic Packing Machine With Weighing has the following advantages, integrating intelligence, high precision and multi-functions, providing strong guarantees for enterprises to achieve efficient, stable and low-cost packaging production:

High precision and stability: the introduction of imported sensors and intelligent algorithm control, small weighing error and stable performance.

Convenient operation: full touch interface, visual parameter setting, easy to learn and use, saving labor training costs.

Strong compatibility: adapt to a variety of bag types and materials, support customized design, and meet different process requirements.

High degree of automation: automatic bagging, weighing, filling and sealing are completed in one, effectively improving production efficiency.

What are the types of Automatic Packing Machine With Weighing?

Automatic Packing Machine With Weighing is mainly divided into two types: single-head weighing and multi-head weighing, suitable for quantitative packaging of granules, powders, flakes, blocks and other materials.

Single-head weighing packaging machine

Structure: storage bin, vibration/screw feeder, single weighing sensor, packaging sealing mechanism, control system.

Output: 5~20 bags/minute (depending on material characteristics).

Applicable materials: small particles (such as seeds, seasonings), fragile materials (such as potato chips, puffed foods), high-value products (such as medicines, health products).

Applicable fields: small batch, high-precision packaging, such as food processing, pharmaceuticals, boutique retail, etc.

Multi-head weighing packaging machine

Structure: main vibration plate, distributor, multiple groups of weighing sensors (8~16 heads), centralized control system, high-speed packaging machine.

Output: 50~200 bags/minute (high-speed models can reach more than 300 bags).

Applicable materials: regular particles (such as nuts, candies), dry powders (such as milk powder, coffee), materials with good fluidity (such as rice, feed).

Applicable fields: large-scale production lines, such as snack foods, quick-frozen products, agricultural product processing, etc.

Technical parameters of Automatic Packing Machine With Weighing

According to the different packaging materials, Automatic Packing Machine With Weighing is mainly divided into three categories: particle weighing packaging machine, powder weighing packaging machine, and liquid weighing packaging machine. The following are the specific technical parameters:

Particle weighing packaging machines are mostly used for quantitative packaging of materials such as rice, seeds, feed, nuts, etc., using vibration feeding or belt conveying. The following figure is a table of parameters for related models:

Powder weighing packaging machines are suitable for materials with poor fluidity such as flour, milk powder, and additives. They are usually equipped with a spiral feeding system to ensure metering accuracy. The following figure is a table of parameters for related models:

Liquid weighing packaging machines are aimed at oils, condiments, chemical liquids, etc., combined with filling and sealing devices to complete leak-free and efficient packaging operations. The following figure is a table of parameters for related models:

How does Automatic Packing Machine With Weighing work?

The structure of Automatic Packing Machine With Weighing includes a feeding system, a weighing system, a control system, and a packaging actuator. The feeding system transfers the material to the high-precision weighing unit by vibration feeding or spiral conveying. The imported sensor collects the weight data in real time and feeds it back to the PLC controller. The system dynamically adjusts the coarse/fine feeding speed through the PID algorithm, quickly fills the coarse feeding stage, and micro-compensates the fine feeding stage to ensure the packaging accuracy of ±0.1%-0.2%. After weighing, the packaging mechanism automatically completes the bag making (supports back sealing/three-side sealing), metering filling, hot melt sealing and date coding.

What are the applications of Automatic Packing Machine With Weighing?

Automatic Packing Machine With Weighing plays a key role in many industries. In the food industry, it is used for the rapid packaging of products such as rice, sugar, nuts, dried fruits, biscuits, etc.; in the chemical industry, it is suitable for the precise measurement of materials such as additives, granular fertilizers, calcium carbonate, resin powder, etc.; in the field of feed and agricultural product processing, it can efficiently package feed pellets, poultry premixes, grains, seeds, etc.; in the field of medicine, some models can also be used for the automatic packaging of small package materials such as herbal pellets and solid drinks. In addition, in emerging scenarios such as e-commerce, logistics packaging, and new retail, the equipment also demonstrates superior flexibility and intelligence, and is an important equipment for promoting industrial upgrading and production automation.

Automatic Packing Machine With Weighing Solution

Automatic Packing Machine With Weighing has a good application space in material property adaptation and industry fields.

Powder with poor fluidity (such as milk powder, additives): Use spiral feeding + vibration to assist in unloading to prevent bridging; the inner wall of the weighing hopper is coated with anti-static material.

Fragile particles (such as potato chips, puffed foods): Use multi-head combination weigher + free fall filling to reduce mechanical extrusion; add buffer baffles to the weighing hopper.

High-viscosity liquids (such as honey, sauces): Equipped with piston pumps or gear pumps, the weighing system uses gross weight mode to avoid wall sticking errors.

Food industry: Multi-head weighers are used for nut packaging (20kg/h, ±1g), and single-head weighers are used for condiments (5kg/bag, ±2g).

Chemical industry: Explosion-proof single-head scale for packaging carbon powder (25kg/bag, ±0.5%), using a sealed structure to avoid dust explosion.
