valve type bag filling machine

1. Product Introduction

The valve type bag filling machine is dedicated automatic packaging equipment supporting full-automatic and semi-automatic dry mortar production lines. It is designed for quantitative filling of dry powder and fine granular building materials into valve-port bags. Adopting screw or pneumatic feeding and fully sealed valve-port filling technology, the machine automatically completes weighing, constant-volume filling, material cutoff and bag dropping procedures. Different from open-mouth packaging equipment, it realizes closed dust-free operation without subsequent bag sewing, solving common industry problems such as dust overflow, low metering accuracy and irregular finished bags. Featuring intelligent PLC control, compact modular structure and stable continuous operation, it is the ideal high-end packaging solution for standardized dry mortar factories and building material production enterprises.

2. Core Advantages

High-precision Weighing & Stable Batch Quality Equipped with high-sensitivity load cells and intelligent dual-speed feeding control system, the equipment maintains stable weighing accuracy within ±0.2%~±0.5%. It ensures consistent net weight for every bag, effectively avoiding material waste and unqualified products, and guaranteeing uniform batch quality.
Fully Sealed Dust-free Operation The unique valve-port closed filling structure prevents powder leakage during the whole packaging process. With zero floating dust, it greatly improves workshop working conditions and fully meets modern environmental protection production standards for dry mortar plants.
High Production Efficiency & Labor Saving Only manual bag hanging is required during operation. Weighing, filling and bag releasing are fully automated. Featuring short packaging cycle and high hourly output, it effectively reduces labor intensity and improves overall line production efficiency.
Strong Material Adaptability It is widely applicable for various dry mortar products and building powder materials, including ordinary construction mortar, functional mortar, fiber-modified mortar, tile adhesive, wall putty powder and gypsum powder. It stably adapts to materials with different fineness and fluidity.
Integrated Modular & Space-saving Design Adopting compact integrated structure, the machine covers small floor area and allows quick installation and commissioning. It can be seamlessly connected with finished product silos to form a continuous automatic production flow.
Durable Structure & Low Maintenance Cost Material contact parts adopt high wear-resistant treatment for long service life. The whole machine runs stably with low failure rate. The humanized structural design facilitates daily cleaning and replacement of vulnerable parts, reducing long-term operation costs.

4. Operation Precautions

Perform comprehensive pre-start inspection before production. Check the firmness of connecting components, sensor sensitivity, air pressure stability and filling nozzle sealing condition. Remove foreign hard impurities inside the machine to avoid jamming and mechanical damage.
Use standard qualified valve-port bags and ensure each bag is firmly sleeved on the filling nozzle to prevent material leakage and weighing deviation. Do not strike or shake the weighing platform during running status.
Operate in strict accordance with production specifications. Hard impurities are prohibited from entering the filling system to protect the screw and nozzle. For damp, caking and fiber-containing mortar materials, maintain stable and uniform feeding speed to avoid blockage.
Strictly implement safety operation regulations. It is forbidden to place hands or tools near the filling nozzle during operation. Immediately stop the machine and cut off the power supply for troubleshooting if abnormal noise, vibration, blockage or excessive weighing error occurs.
Thoroughly clean residual powder and condensed materials inside the machine after each working shift. Prevent material moisture absorption and solidification to ensure packaging accuracy and extend equipment service life.
Carry out regular maintenance and systematic calibration. Periodically calibrate the weighing system to guarantee metering precision. Timely replace worn nozzles, sealing parts and vulnerable accessories to maintain stable mechanical performance.
Keep the electrical control cabinet dry and dust-proof with reliable grounding protection. Only professional technicians are allowed to maintain electrical components. Always cut off the total power supply before equipment maintenance and overhaul.

6. FAQ

Q1: What is the difference between a valve type bag filling machine and an open mouth bag packing machine?

A: The valve type filling machine adopts fully sealed closed filling without bag sewing procedure, featuring zero dust leakage, neat bag shape and higher finished product grade. It is more suitable for fine powder and high-end mortar products. The open-mouth machine has wider material adaptability but generates more dust and requires manual bag sealing. Valve type machines are the preferred choice for modern standardized dry mortar plants.

Q2: What causes unstable weighing accuracy during operation?

A: Common causes include uncalibrated weighing sensors, unstable air pressure, blocked filling nozzles, residual caking materials and improperly installed bags. Users can solve the problem by recalibrating the weighing system, stabilizing air pressure, cleaning internal blockages and standardizing bag hanging operations.

Q3: How to solve material blockage during packaging?

A: Material blockage is mainly caused by damp raw materials, powder agglomeration and uneven feeding speed. Keeping raw materials dry, maintaining stable feeding volume and cleaning the machine thoroughly after each shift can effectively avoid blockage.

Q4: Can this machine pack fiber-modified dry mortar?

A: Yes. The optimized anti-blocking feeding structure effectively prevents fiber winding and material accumulation. It can stably and efficiently package various fiber-containing mortars and fine powder building materials.

Q5: Is equipment customization supported?

A: Full customization is available. We can adjust packaging weight range, feeding speed, equipment size and supporting configurations according to customer output demand, material characteristics and workshop layout.

Q6: What are the core advantages of valve-port packaging for dry mortar?

A: Valve-port packaging features dust-free operation, beautiful bag molding, low bag cost and no secondary sewing required. It meets environmental protection production standards, improves workshop cleanliness and greatly enhances the market competitiveness of finished mortar products.
