valve bagging machine

The valve bagging machine is a professional automatic quantitative packaging device specially matched with dry mixed mortar production lines. It is designed for high-efficiency filling and weighing of dry powdery and fine granular building materials. Different from open-mouth bagging equipment, this machine is dedicated to sealed valve-port kraft bags and plastic valve bags, realizing automatic metering, dust-free filling, quantitative packaging and bag releasing.

It is widely applicable for finished dry mortar products such as tile adhesive, wall putty, plastering mortar, masonry mortar, waterproof mortar and thermal insulation mortar. With integrated weighing sensor and intelligent microcomputer control system, the machine completes accurate fixed-weight packaging in one single process. The fully enclosed filling structure effectively eliminates flying dust, improves workshop environment, and becomes the preferred packaging equipment for high-standard environmentally friendly dry mortar factories.

• 2.1 High-precision Quantitative Weighing

  Equipped with high-sensitivity load cell sensors and intelligent weighing controller, the machine adopts dual-speed coarse and fine feeding control. The weighing error is stably controlled within ±0.2%~±0.5%. Each bag of dry mortar maintains uniform net weight, ensuring standardized product delivery and avoiding customer complaints caused by weight deviation.

• 2.2 Fully Enclosed Dust-free Packaging

  The unique valve-bag closed filling structure avoids material overflow and dust diffusion during packaging. Cooperated with the centralized dust removal system of the dry mortar plant, it realizes almost dust-free operation. It reduces material waste, improves workshop working conditions and meets strict environmental protection production standards.

• 2.3 High Packaging Efficiency & Stable Operation

  Adopts impeller / screw / air-flow feeding structure according to material characteristics. It supports continuous cyclic filling and automatic bag dropping. The whole packaging process runs smoothly without blockage or material leakage. It perfectly matches the continuous output speed of automatic dry mortar production lines to improve overall factory throughput.

• 2.4 Intelligent & Simple Operation

  Equipped with PLC and touch screen HMI. Operators only need to sleeve the valve bag manually. The machine automatically completes weighing, filling, material stopping and bag falling. Multiple packaging formulas and weight parameters can be stored for one-click switching of different mortar products. Operation is intuitive and labor-saving.

• 2.5 Strong Material & Bag Compatibility

  It adapts to all kinds of dry flowing powder materials produced by dry mortar plants, including ordinary mortar powder, fine powder additives and superfine putty powder. It is fully compatible with standard valve-port kraft bags and plastic composite valve bags, with strong versatility.

• 2.6 Robust Structure & Low Maintenance Cost

  The whole machine adopts thickened wear-resistant steel structure and anti-blockage feeding design. It features stable operation, low noise and low failure rate. All vulnerable parts are standard universal accessories with low replacement cost and convenient daily maintenance.

• 2.7 Complete Safety Protection Mechanism

  Built-in bag-missing detection, overload alarm, material blockage protection and emergency stop function. The equipment automatically stops and alarms under abnormal working conditions to prevent equipment damage and operational safety risks.

• 4.1 Pre-operation Inspection & Calibration

  Before startup, check the power supply, pneumatic system, transmission components and weighing sensors. Ensure no foreign blocks or accumulated powder inside the feeding chamber. Calibrate the weighing system regularly to guarantee accurate metering. Confirm all safety protection devices and emergency stop functions are effective.

• 4.2 Standard Bagging Operation

  Use standard qualified valve bags for packaging; deformed or damaged bags are prohibited. Place the valve bag firmly on the filling nozzle. Do not touch the operating mechanism during equipment running. Strictly prevent hard sundries and iron blocks from entering the machine to avoid mechanical jamming and damage.

• 4.3 Real-time Operating Monitoring

  Monitor equipment running status continuously during production. Immediately stop the machine for troubleshooting in case of abnormal noise, vibration, material blockage, leakage or inaccurate weighing. It is forbidden to modify system parameters and weight data arbitrarily during normal production. Keep the dust removal pipeline unobstructed.

• 4.4 Daily Cleaning & Routine Maintenance

  After daily shutdown, clean residual powder inside the feeding impeller, screw and filling nozzle to prevent material caking and blockage. Regularly lubricate transmission bearings and movable parts. Inspect the wear of internal components, sealing parts and bagging accessories, and replace vulnerable parts timely. Clean dust removal accessories periodically.

• 4.5 Safety Operation Specifications

  All operators must receive professional pre-job training and wear standard labor protection equipment. Keep the electric control cabinet dry and ventilated to avoid electric faults. Completely cut off power and air sources during equipment maintenance and overhaul.

• 4.6 Long-term Shutdown Maintenance

  For long-term shutdown, thoroughly clean all residual materials inside the machine. Perform rust-proof, moisture-proof and dust-proof treatment on mechanical structures and electrical components to extend equipment service life.

• 5.1 Full-automatic Dry Mixed Mortar Production Line

  Special supporting packaging equipment for intelligent dry mortar plants, used for quantitative packaging of masonry mortar, plastering mortar, tile adhesive, anti-crack mortar and thermal insulation mortar.

• 5.2 High-standard Green Building Material Factories

  Suitable for environmentally friendly production workshops requiring low dust and closed operation, meeting high-standard factory environmental protection and sanitation requirements.

• 5.3 Fine Powder Building Material Production

  Ideal for packaging superfine putty powder, gypsum powder, high-grade bonding mortar and other fine powder materials with high fineness and easy dusting.

• 5.4 Industrial Powder Processing Industry

  Widely used for quantitative packaging of non-corrosive dry powder materials such as mineral powder and chemical powder with good fluidity.

• 5.5 Large-scale Commercial Mortar Batching Base

  Adapt to high-volume continuous packaging operation of large mortar production bases, improving packaging standardization and production efficiency.

• Q1: What kind of bags does the valve bagging machine use?

  A1: This machine is specially designed forvalve-port bags, including kraft paper valve bags and plastic composite valve bags. It is not applicable for open-mouth bags. The sealed valve bag packaging features neat bag shape, less dust and beautiful finished stacking effect.

• Q2: What dry mortar products can this machine pack?

  A2: It can pack all conventional dry mortar products produced by dry mixed mortar production lines, such as tile adhesive, wall putty, plastering mortar, masonry mortar, waterproof mortar, thermal insulation mortar and other powdery materials with good fluidity.

• Q3: Is the weighing accuracy stable?

  A3: Yes. Equipped with high-precision sensors and intelligent weighing system, it adopts dual-speed feeding correction technology. The long-term operating error is controlled within ±0.5%, ensuring stable and consistent bag weight.
