An automatic conveying packaging machine is industrial-grade equipment designed to fill, weigh, seal, and discharge dry powder or granular materials into bags automatically with minimal human intervention. These machines are widely used in construction materials, building chemicals, mining, and dry mortar industries for packaging products like putty powder, gypsum, cement, fly ash, and silicon powder with precision and speed.

What Is an Automatic Conveying Packaging Machine?

An automatic conveying packaging machine integrates a conveying system with a quantitative filling and sealing unit. It automatically handles the complete bagging process from material feeding to bag discharge. Depending on the material type, fluidity, particle size, and bag format, the machine uses different valve port configurations and opening mechanisms to ensure accurate, dust-free, and efficient packaging.

These machines are built for high-volume production environments where consistency, speed, and low maintenance downtime are critical requirements. They replace manual bagging labor, reduce product waste, and improve weighing accuracy across every shift.

Core Product Range

The product lineup covers a comprehensive range of automatic and semi-automatic packaging equipment designed for different material types and production scales:

1. Putty powder packaging machine – Engineered specifically for wall putty, dry mortar, and similar fine construction powders requiring precise dosing and hermetic sealing
2. Fillet bag packaging machine – Designed to handle corner-sealed bag formats used in specialty chemical and construction product packaging
3. Semi-automatic packaging machine – Suited for medium-scale operations that require human bag placement with automated weighing and filling
4. Single-bucket gravity packaging machine – Uses gravity-assisted flow for free-flowing granular or coarse powder materials at a cost-effective operational level
5. Piston packaging machine – Applies mechanical piston action to meter viscous, semi-liquid, or paste-type materials with high accuracy

Valve Port and Opening Types: Choosing the Right Configuration

Different powder materials behave differently during packaging. Fluidity, particle size, moisture sensitivity, and bulk density all determine which valve port or opening mechanism delivers the best filling speed, accuracy, and seal quality. The following configurations are available:

Valve Port Options:

• 空気弁ポート – Uses controlled air pressure to assist filling of ultra-fine, aerated powders. Ideal for materials prone to dusting and clumping, ensuring clean, low-emission bag filling
• 超音波シールバルブポート – Applies high-frequency ultrasonic energy to create an airtight, hermetic seal at the bag mouth. Recommended for moisture-sensitive powders such as dry mortar, gypsum, and specialty construction chemicals
• Impeller type – A rotating mechanical impeller pushes dense or semi-granular materials into the valve bag at high speed. Delivers fast fill rates and firm bag compaction, commonly used for putty powder, cement, and mineral powder
• Air floatation type – Fluidizes fine powders using air pressure, allowing smooth gravity-assisted flow into the bag. Best suited for ultra-light or highly aerated powder materials
• スパイラルバルブ – A screw-driven spiral mechanism provides gentle, metered material flow. Preferred for fluffy, lightweight, or dust-prone powders to minimize air entrapment and product loss
• Gravity valve port – A straightforward gravity-fed valve system that allows free-flowing materials to fall into the bag under their own weight. Low energy consumption, low maintenance, and easy to operate

Opening Mechanism Options:

• Screw opening – A mechanical screw controls the rate and volume of material discharge, delivering precise metered filling for powders with variable fluidity
• Gravity opening – Relies on material weight and gravity to release product into the bag, suitable for coarse or free-flowing granular materials
• ベルト式開口部 – A belt-driven mechanism manages bag mouth opening and material flow in coordinated sequence, often used in high-speed automated lines
• Big bag (FIBC) option – Supports jumbo bag or bulk bag filling for large-volume shipments, typically ranging from 500KG to 1500KG per bag

Why Selecting the Right Machine Type Matters

Choosing the wrong packaging machine for a given material leads to weighing inaccuracies, bag sealing failures, excessive dust emissions, and increased machine downtime. Each material category requires a matched combination of feeding mechanism and valve port type:

• Fine construction powders like putty and dry mortar perform best with impeller type or ultrasonic sealing configurations
• Coarse or granular materials such as quartz sand or compound fertilizer work efficiently with gravity valve or belt type setups
• Ultra-light or aerated materials like micro-silicon powder require air floatation or spiral valve port designs
• Moisture-sensitive or hygroscopic products need ultrasonic sealed valve bag packaging to maintain shelf stability

よくある質問

What is the difference between impeller type and air floatation type packaging machines? The impeller type uses a mechanical rotating blade to push material into the bag, making it ideal for dense, semi-granular, or abrasive powders. The air floatation type uses pressurized air to fluidize and flow fine, lightweight powders smoothly into the bag without mechanical contact, reducing wear on the machine and the material.

How often should a putty powder packaging machine be serviced? Daily cleaning and inspection, weekly lubrication, monthly weighing calibration, and quarterly mechanical inspection are the recommended intervals. High-output production lines may require more frequent maintenance cycles.

Which packaging machine is suitable for micro-silicon powder? The 210L micro-silicon powder packaging machine with air floatation valve port configuration is specifically designed for ultra-fine, low-density silicon powder, ensuring controlled, dust-free filling with high accuracy.

Can one machine handle multiple types of powder materials? Yes. Many automatic conveying packaging machines support configurable valve port and opening options. However, the optimal configuration depends on the specific material properties. Contacting the technical sales team helps identify which machine model and port type are correct for your materials.
