Bag-feeding powder packaging machine

What is bag-feeding powder packaging machine?

Bag-feeding powder packaging machine often use screw metering, which reduces spillage of materials such as flour, coffee powder, milk powder, and laundry detergent. The metering error is typically controlled within ±1%.

Parts of the bag-feeding powder packaging machine that come into contact with the material are typically made of 304 or 316 stainless steel, making them durable and corrosion-resistant. The packaging speed typically ranges from 15 to 80 bags per minute. It supports three-side seal bags, four-side seal bags, stand-up pouches, and flat bags, meeting the packaging needs of various powder products.

What are the structural components of a bag-feeding powder packaging machine?

The bag-feeding powder packaging machine primarily consists of the following components: an automatic bag loading device, a bag storage system, a bag opening mechanism, a metering and filling system, an exhaust system, a heat sealing mechanism, a transmission system, and a control system.

The operating principle is as follows: The control system issues a command, and the transmission system transports empty bags to the workstation. Subsequently, the automatic bag loading device retrieves a bag from the bag storage, and the bag opening mechanism precisely opens the bag using a suction cup. The metering and filling system immediately pours a precisely measured amount of powder into the bag, while the exhaust system removes air from the bag to prevent splashing. After filling, the bag is transported to the heat sealing mechanism for heat sealing. Finally, the finished bag is delivered by the transmission system.

What are the advantages of a bag-feeding powder packaging machine?

Bag-feeding powder packaging machines offer significant advantages: significantly improved production efficiency, with automated operation speeds reaching 5-10 times that of manual operation. High metering accuracy reduces material waste and lowers costs. The enclosed design offers easy cleaning and superior hygiene, meeting food and pharmaceutical requirements. High flexibility allows adaptation to various bag types and materials by changing molds and adjusting parameters. Reliable operation, equipped with an advanced control system and fault alarms, ensures stable production. Integrated inkjet traceability supports batch numbers and dates, meeting quality management requirements.

What types of bag-feeding powder packaging machines are there?

Bag-feeding powder packaging machines primarily include vertical, spiral vertical, multi-lane, and large bag models. These machines differ in their structure, metering method, station, and capacity, meeting diverse packaging needs for small bags at high speed and high precision, medium-volume packaging, and large bags with heavy loads.

Vertical powder packaging machine: Utilizing roll film for on-site bag making, this machine integrates bag making, metering, filling, and sealing. It features a compact structure, small footprint, and quick and convenient material and size changes. This equipment is suitable for various bag types, including three-side seal bags, back seal bags, and gusseted stand-up pouches. Its packaging speed is typically low to medium, approximately 20-50 bags/minute, suitable for small-batch packaging, typically ranging from 1 gram to 1000 grams.

Vertical Screw Conveyor Powder Packaging Machine: This machine features a vertical design and utilizes a screw-type metering mechanism, making it an ideal metering method for powder packaging. It boasts extremely high metering accuracy, effectively handles powders with varying flowability, and offers excellent dustproof performance. This equipment is suitable for various bag types, including three-side seal bags, back seal bags, and stand-up pouches. Packaging speed varies depending on material characteristics and accuracy requirements, typically ranging from 15 to 45 bags per minute. This equipment is suitable for small to medium batch packaging, with typical packaging capacities ranging from 5 grams to 5000 grams.

Multi-lane bag-feeding powder packaging machine: This machine consists of multiple vertical machines (typically 2-14 lanes) connected in parallel, operating synchronously. This is equivalent to running multiple production lines in parallel, offering extremely high production efficiency and is ideal for large-volume production.This machine is designed for small-sized three-side-seal and back-seal bags. It boasts extremely high packaging speeds, reaching hundreds of bags per minute. It's ideal for small-volume packaging, typically ranging from 1g to 100g. Typical applications include stick packs of seasonings, ground coffee, and other products.

Large Bag Bag-feeding powder packaging machine: Designed for large, heavy-duty packaging. Featuring a robust structure, it typically features a high-capacity screw or gravity-feeding system and a high degree of automation, often integrating automatic bag loading and robotic palletizing.This machine is used for pre-formed large, open-top bags, such as valve bags, PE bags, and woven bags. While packaging speeds are slower, it prioritizes precision and stability, typically running 2-10 bags per minute. It's suitable for large-volume packaging applications, ranging from 5kg to 50kg or even higher.

Bag-feeding Powder Packaging Machine Price

Semi-automatic bag-feeding powder packaging machines offer basic functionality, primarily performing basic operations such as metering, filling, and bag sealing. They are relatively affordable, typically ranging from $3,000 to $10,000, making them suitable for small-scale production or startups with limited budgets. Fully automatic bag-feeding powder packaging machines are the most common type. They offer comprehensive functionality, automating the entire bag-making, metering, filling, sealing, coding, and counting processes. Optional features include nitrogen filling for freshness preservation, weight rejection, and material level detection. Prices range from approximately $10,000 to $20,000, increasing depending on the number of filling heads, accuracy, and optional features. Fully automatic rotary bag-feeding powder packaging machines, suitable for ultra-large-scale production, integrate the highest levels of automation and intelligence. They feature dozens of workstations and incorporate advanced features such as high-precision weighing, visual inspection, and robotic palletizing to maximize production capacity. Consequently, they command the highest prices, typically starting at over $20,000.

What are the features of bag-feeding powder packaging machines?

The bag-feeding powder packaging machine can automatically grasp and precisely open pre-made bags made of various materials and specifications, such as composite film and aluminum foil bags, without manual intervention. Using a screw or weighing system, it precisely controls the filling volume of materials such as flour, milk powder, and seasoning powder, ensuring consistent weight per bag and minimizing waste. After filling, the bag is automatically heat-sealed (some models support vacuum sealing), and trimming and embossing are also available as needed to prevent moisture and leakage. The finished packages are automatically transported to the next stage. High-end models also feature integrated weight detection and leak detection to automatically reject defective products. The machine supports a variety of powder materials, such as those that are prone to moisture absorption and dust generation. Parameters such as fill volume and sealing temperature can be quickly adjusted via the touchscreen, making it suitable for small-batch, multi-product production.

What powder materials are suitable for the bag-feeding powder packaging machine?

Bag-feeding powder packaging machine is used for powder materials in many industries such as milk powder, protein powder, seasoning, flour, powdered sugar, dye, coating, plastic powder, detergent, pharmaceutical powder, traditional Chinese medicine powder, health care products, fertilizer, seed treatment agent and metal powder.
