In the fields of new material industrial manufacturing, matting powder, as a key functional powder, is widely used in wood coatings, polyurethane coatings, coil coatings, UV coatings, automotive interior and exterior coatings and other industries. Similar light-weight powders include fumed silica, silicon dioxide, carbon black, pearlescent powder, transparent powder, flame retardants, ceramic raw materials, lithium battery raw materials, graphene, magnesium hydroxide, zinc oxide and magnesium oxide. These materials generally feature large bulk volume, good fluidity, high gas content, fine particle size, and easy moisture absorption and agglomeration, putting forward high requirements for the packaging process.
Aiming at the packaging difficulties of matting powder and various ultra-fine powders, the fully automatic powder heavy bag packaging machine series launched by Marchi Packaging Equipment provides technical support for chemical and new material manufacturers in packaging automation upgrading. As an influential original manufacturer with years of experience in powder packaging machinery, the equipment relies on fully automatic design, vacuum packaging technology and efficient system integration. With a nationwide service network, it is committed to helping manufacturers reduce costs and improve efficiency.
Core Equipment Advantages: Tailored for Powder Characteristics
The fully automatic powder heavy bag packaging machine is compatible with various packaging materials such as laminated kraft paper bags, woven bags and plastic bags, with a packaging weight range of 5 to 25 kilograms. Targeting the physical characteristics of matting powder and similar ultra-fine powders, the equipment offers support in the following aspects:
- Fully Automatic Operation: The equipment completes integrated packaging procedures including automatic metering, automatic bag feeding, automatic filling and automatic heat sealing and sewing. All links operate coordinately to reduce manual intervention and lower long-term labor investment.
- Precision Control: The weighing machine adopts a vertical screw feeding structure directly driven by a servo motor, with packaging accuracy up to ≤±0.1%～0.2%. The screw rotates for feeding according to control signals, and cooperates with high-precision weighing sensors and controllers to process data in real time and ensure accurate metering of each bag.
- Vacuum Packaging Design: Adopts vacuum negative pressure material suction mode, and draws materials into the packaging bag by using the pressure difference between the vacuum chamber and the feeding device. It effectively removes excess gas inside the powder, avoids bag bulging, and keeps finished packages compact and solid.
- Dust and Moisture Prevention: The whole equipment adopts a fully enclosed dustproof structure. The efficient vacuum system can quickly extract air and moisture inside the bag, greatly reducing the risk of dust overflow and environmental pollution, and solving the problem of decreased dispersibility of matting powder caused by moisture absorption.
- Intelligent Control System: Integrated with PLC program control and human-machine interface operation, operators can easily adjust packaging speed and metering parameters. The system has automatic protection functions for inverters, sensors and other components.
Packaging Process: Full-process Automation from Filling to Palletizing
The complete matting powder packaging process covers bag supply, bag picking, filling, vacuum sealing, inspection and final palletizing and warehousing, with all links connected in an orderly manner. The applicable bag length ranges from 500mm to 1000mm.
Step 1: Bag Supply and Bag Picking
The equipment is equipped with a bag storage warehouse for pre-storing an appropriate number of packaging bags. The bag picking and arranging device takes out bags one by one and performs centering positioning to ensure accurate bag position.
Step 2: Bag Feeding and Bag Opening
The bag is centered and positioned by the bag picking and arranging device, then conveyed to the bag clamping station by the mechanical arm. After the bag mouth is shaped and positioned by the guiding device, the pre-opening device assists in opening the bag mouth. The blade of the bag feeding manipulator inserts into the bag mouth, and air grippers clamp both sides of the bag mouth simultaneously.
Step 3: Bag Clamping, Discharging and Filling
After the bag clamping and discharging device firmly clamps the bag mouth, the vertical single screw feeding device starts feeding. An independent air extraction system is configured during discharging to solve the gas problem in powder packaging. The weighing sensor monitors the material weight inside the bag in real time and automatically stops feeding when reaching the preset value.
Step 4: Bag Pushing and Bag Mouth Guiding
After filling, the bag holding and pushing device smoothly transports the full material bag to the sealing station. The bag mouth guiding device arranges the bag mouth to eliminate wrinkles and skew, preparing for sealing.
Step 5: Vacuum Sealing
Vacuum pumping is completed in the vacuum chamber to remove air inside the bag. Subsequently, the equipment automatically completes integrated heat sealing and sewing to ensure tight sealing of packaging bags.
Step 6: Conveying and Palletizing
Sealed packaging bags enter the conveying system and are transported to the automatic palletizer via the belt conveyor. The palletizing manipulator stacks the packaging bags regularly on pallets according to set parameters, realizing full-process automation.
Common Customer Pain Points and Solutions
Pain Point 1: Unstable packaging accuracy leading to raw material waste
Solution: Marchi equipment adopts servo motor directly driven screw feeding, matched with high-precision weighing sensors, controlling packaging accuracy within ≤±0.1%～0.2%. Equipment parameters can be flexibly adjusted according to production needs, greatly reducing material loss.
Pain Point 2: Matting powder is easy to absorb moisture and agglomerate, affecting use effect
Solution: The equipment is equipped with an efficient vacuum system, which reduces the vacuum degree inside the packaging bag below -0.095MPa during packaging, effectively removing oxygen and moisture, maintaining the original dispersion performance of matting powder and avoiding agglomeration caused by moisture absorption.
Pain Point 3: Severe dust emission polluting the production environment
Solution: The whole equipment adopts a fully enclosed dustproof structure, and the whole process from bagging to sealing operates in a closed space. Meanwhile, it is equipped with an independent dust removal system to reduce material waste and environmental pollution.
Pain Point 4: Low manual packaging efficiency and high labor cost
Solution: The whole process including bag supply, bag feeding, filling, sealing and palletizing operates automatically. It saves labor expenditure, reduces long-term employment costs, and helps manufacturers steadily increase production capacity.
Pain Point 5: Loose sealing of packaging bags leading to easy damage during transportation
Solution: The equipment adopts integrated heat sealing and sewing design, with double sealing to ensure sealing effect. It is compatible with various bag materials such as laminated kraft paper bags, woven bags and plastic bags, featuring strong adaptability and firm sealing.
