valve bag filling machine

The mortar valve bag filling machine is a professional automatic quantitative filling equipment customized for powdery and granular mortar materials, including dry powder mortar, bonding mortar, waterproof mortar, thermal insulation mortar, and putty powder. Adopting a closed valve bag filling process, it is perfectly matched with large-scale industrial mortar production lines.
Integrated with intelligent weighing, pneumatic feeding, automatic dust removal and quantitative start-stop functions, the machine solves the common problems of traditional open filling such as serious dust emission, inaccurate metering and cumbersome bagging. It can automatically complete the whole process of bag sleeving, feeding and filling, precise weighing and automatic bag dropping.
With a modular structure design, the machine features strong compatibility and supports valve bag packaging specifications from 10kg to 50kg. As the core supporting equipment for dry mortar production lines, it greatly improves the automation level and production efficiency of mortar packaging and reduces labor and production costs.

• High Precision & Low Error: Equipped with high-precision intelligent weighing sensors and variable-frequency speed regulation feeding technology, the filling metering accuracy is controlled within ±0.2%-±0.4% with a single bag qualification rate over 95%. It effectively avoids over-filling or under-filling of mortar materials, ensures standardized factory quality and reduces material loss.
• Dust-Free & Environment-Friendly Operation: Closed filling structure matches the professional dust removal system, which effectively suppresses flying dust during the mortar packaging process. It improves the on-site working environment, meets industrial environmental protection standards, and reduces material waste caused by dust dispersion.
• High Efficiency & Labor Saving: Realizes semi-automatic and automatic cyclic filling operation. Workers only need to finish bag sleeving, and the machine automatically completes weighing, filling and bag dropping. It greatly saves labor costs, improves packaging speed, and is suitable for mass continuous production.
• Wide Compatibility & Strong Stability: Adaptable to various dry mortar materials with different fineness and fluidity. The whole machine adopts thickened industrial steel structure, with anti-corrosion and wear-resistant parts, stable operation, low failure rate and long service life.
• Intelligent & Easy Operation: Equipped with an intelligent touch control panel, supporting parameter setting of weighing value, filling speed and delay time. It features simple operation, clear data display and convenient daily adjustment and maintenance.

• Pre-Operation Inspection: Check the air pressure, power supply and circuit before starting the machine. Confirm that all connecting parts, fasteners and sealing components are firm and intact, and no foreign matters are left inside the feeding cavity.
• Standard Operation: Operators must receive professional training before working. It is forbidden to put hands or tools into the filling port during machine operation to avoid safety accidents.
• Material Requirements: It is strictly prohibited to fill mortar materials mixed with large impurities, hard blocks or iron sundries to prevent blocking the machine or damaging the feeding and weighing system.
• Environment Requirements: The equipment shall be placed on a flat and solid cement ground. The working environment shall be dry, ventilated and dust-proof, avoiding long-term operation in humid and corrosive environments.
• Daily Maintenance: Clean the residual mortar dust inside and outside the machine after daily work. Regularly lubricate moving parts, check sensor sensitivity and air circuit tightness to ensure stable operation.
• Failure Handling: In case of abnormal noise, blocked feeding or inaccurate weighing, stop the machine immediately for inspection. It is forbidden to disassemble and repair the machine with electricity and air pressure on.
• Power Off Protection: Cut off the power supply and air source completely when the machine is not in use for a long time or during equipment maintenance.

• Dry Mortar Production Plants: Special packaging for ordinary dry mixed mortar, masonry mortar, plastering mortar and floor mortar.
• Special Building Material Factories: Suitable for packaging of waterproof mortar, thermal insulation mortar, repair mortar, adhesive mortar and other functional mortar products.
• Putty & Powder Coating Industry: Applicable for quantitative packaging of interior and exterior wall putty powder, building talc powder and other powdery building materials.
• Small & Medium-Sized Packaging Production Lines: Ideal for semi-automatic and full-automatic matching production lines of building powder materials, supporting batch standardized packaging operations.

• Q1: What types of mortar materials can this machine pack? A1: It is mainly suitable for all kinds of dry powdery and fine granular mortar materials, including dry powder mortar, waterproof mortar, thermal insulation mortar, bonding mortar, wall putty powder and other building powdery materials. It is not applicable for wet mortar or materials with large particles.
• Q2: What is the weighing accuracy of the equipment? A2: The standard metering accuracy is ±0.2%-±0.4%. The accuracy is stable for long-term continuous operation, which can meet the national industrial packaging standard requirements and effectively control product weight error.
• Q3: Can the filling weight be adjusted arbitrarily? A3: Yes. The equipment supports free adjustment within the range of 10-50kg. Users can set the target weight, fast and slow feeding parameters through the touch screen according to production needs.
• Q4: Why does the machine have inaccurate weighing during operation? A4: Common reasons include dust accumulation on the weighing sensor, unstable air pressure, blocked feeding port, or uneven material fluidity. It can be solved by cleaning the sensor, adjusting air pressure and sorting out material impurities.
• Q5: Is the machine easy to cause dust leakage? A5: No. The machine adopts closed valve bag filling design, matched with a special dust removal interface and dust removal system. The whole filling process is sealed with little dust, which meets environmental protection production requirements.
• Q6: What is the daily maintenance work of the equipment? A6: It is necessary to clean surface and internal dust after work, check air circuit and circuit regularly, lubricate moving parts, and calibrate the weighing system regularly to ensure long-term stable operation of the equipment.
