Multi-Lane Powder Stick Pack Machine

Product Overview

This multi-lane powder stick pack machine is designed for producing several narrow back-sealed sachets from one roll of packaging film. Depending on the selected machine width and sachet dimensions, the system can be configured with different lane quantities for various production requirements.

Dry powder is supplied to the upper feeding and dosing section. Each packaging lane is equipped with a corresponding auger-dosing path that measures and releases the preset portion into the formed sachet. The packaging film is unwound, aligned, divided into multiple lanes, and pulled downward by a servo-controlled film system.

Each lane then completes bag forming, powder filling, longitudinal back sealing, horizontal sealing, cutting, and finished-sachet discharge. Long augers, short augers, or short-auger-and-cup configurations are listed for different product and portion requirements.

The machine is suitable for dairy-product manufacturers, beverage-powder factories, seasoning producers, nutritional-product companies, coffee processors, flour and starch packers, and contract packaging businesses. Final suitability depends on powder flowability, bulk density, moisture absorption, dust generation, target dose, sachet width, and packaging-film performance.

Applications

This machine is suitable for dry powders that can be consistently transferred and dosed by an auger system. The auger design and hopper configuration should be selected according to powder density, flowability, moisture sensitivity, dust level, and required portion size.

This machine is suitable for:

• Milk powder
• Protein powder
• Coffee powder
• Cocoa powder
• Flour
• Starch
• Seasoning powder
• Chili powder
• Matcha powder
• Instant beverage powder
• Powdered sugar
• Baking powder
• Nutritional powder
• Herbal powder
• Plant extract powder

A material test is recommended for powders with high moisture content, strong oil content, poor flowability, severe dust generation, large fibers, irregular particles, or a tendency to bridge or compact inside the hopper.

Main Features

1. Flexible Multi-Lane Configuration

The series supports different lane quantities according to the selected machine width, sachet width, film width, required output, and powder-dosing arrangement.

2. Parallel Sachet Production

All configured lanes perform dosing, filling, forming, sealing, and cutting simultaneously, increasing total output without requiring several separate packaging machines.

3. Auger Powder Dosing

Long-auger, short-auger, and short-auger-with-cup configurations are available for powders with different flow characteristics, portion volumes, and packaging requirements.

4. Narrow Back-Sealed Sachets

Each lane produces a slim sachet with a longitudinal back seal, suitable for single-use portions of beverage powder, seasonings, nutritional powder, coffee, and similar products.

5. Servo Film-Pulling System

The servo-driven film mechanism advances the packaging material according to the preset bag length and coordinates film movement across all active packaging lanes.

6. Adjustable Bag Length

The documented bag-length range is 50–180 mm. Sachet width is determined by the selected model, lane arrangement, and forming components.

7. PLC and Touch-Screen Control

The control system coordinates powder dosing, film movement, sealing temperature, cutting, and machine operation through a centralized touch-screen interface.

8. Film Alignment and Monitoring

The documented film-correction and film-break detection functions help maintain roll-film alignment and can trigger an alarm or machine stop when abnormal film movement is detected.

9. Multiple Cutting Styles

Straight cutting, zigzag cutting, rounded cutting, and die-cut formats can be configured according to the required sachet edge and opening method.

10. Stainless-Steel Machine Structure

The supplied product information describes a 304 stainless-steel machine structure designed for cleaner powder-packaging environments and routine production-area maintenance.

Working Principle

Powder is supplied to the upper hopper, where it enters the selected auger-dosing system. Each packaging lane has a corresponding dosing path that measures and releases the required powder portion.

Roll-fed packaging film is unwound and guided through the film-alignment system. The film is divided according to the selected lane quantity and directed into the individual bag-forming units. A servo-driven mechanism pulls the film downward to the preset sachet length.

Each forming unit shapes the film around its filling tube. The longitudinal sealing section creates the back seam, and the measured powder is discharged into the partially formed sachet. The horizontal sealing system then closes the sachet ends.

Finally, the cutting mechanism separates or shapes the completed sachets according to the selected cutting style. Finished packages fall from the machine for collection or transfer to downstream equipment.

Process Flow:

Powder Feeding → Multi-Lane Distribution → Auger Dosing → Film Unwinding → Film Alignment → Film Splitting → Sachet Forming → Filling → Back Sealing → Horizontal Sealing → Cutting → Discharge

Machine Details

1. Powder Feeding Hopper

The upper hopper receives dry powder and supplies it to the multi-lane dosing section. Hopper and feeding arrangements should be matched to powder flowability and dust characteristics.

2. Multi-Lane Auger Dosing System

Each lane uses a corresponding auger-dosing path to control powder discharge. Auger design should be selected according to product density, target portion, and feeding performance.

3. Film Unwinding Assembly

The film holder supports the roll material and feeds it continuously through the guide rollers toward the film-alignment and bag-forming sections.

4. Film Correction System

The alignment mechanism helps maintain the correct lateral position of the film as it moves through the multi-lane packaging process.

5. Servo Film-Pulling Mechanism

The servo-driven pulling system advances the film according to the selected sachet length and synchronizes movement with sealing and cutting operations.

6. Multi-Lane Bag Formers

The forming units convert the divided film into multiple narrow packaging lanes and guide each film section around its corresponding filling tube.

7. Longitudinal Back-Sealing Units

Each packaging lane has a vertical sealing position that closes the rear seam after the film has been shaped around the filling tube.

8. Horizontal Sealing Unit

The horizontal jaws close the upper and lower ends of the sachets and separate consecutive filling cycles.

9. Cutting System

The cutting section creates straight, zigzag, rounded, or specially shaped sachet edges according to the selected machine configuration.

10. Touch-Screen Control Panel

The operator interface provides access to bag length, temperature settings, operating speed, dosing controls, alarms, and machine start or stop functions.

Technical Parameters

Packaging & Shipping

The final packing method, shipping dimensions, gross weight, and number of shipping cases depend on the selected machine model, lane quantity, auger-dosing configuration, feeding system, discharge conveyor, and other accessories.

Before shipment, the machine should be tested using the buyer’s approved powder, target dose, sachet dimensions, packaging film, printed artwork, and cutting requirements. The auger-dosing units, film alignment, servo pulling system, sealing temperatures, cutting positions, alarms, and control functions should be checked against the confirmed order.

Powder-contact sections should be cleaned before packing, and moving components should be secured against movement during transportation. Moisture protection should be arranged according to the final shipping plan.

The final packing method, shipping dimensions, and gross weight will be confirmed according to the selected machine configuration.
