automatic cement packing machine

The automatic cement packing machine is a professional quantitative powder packaging equipment, specially designed for valve bag packaging of cement, dry mixed mortar, tile adhesive, wall putty, waterproof mortar and other powdery building materials. It is a core supporting device for dry mortar production lines and cement production plants.

Adopting advanced PLC intelligent control system and high-precision weighing sensors, the machine automatically completes material feeding, quantitative filling, weighing, bag sealing and bag dropping. It effectively replaces traditional manual packaging, realizes stable, high-efficiency and dust-free packaging operation, ensures uniform weight of finished bags, avoids material loss, and meets large-scale and standardized production requirements of modern building material factories.

• High Weighing Accuracy:Equipped with high-sensitivity digital weighing sensors, the machine features precise quantitative control. The packaging error is controlled within ±0.3kg, ensuring standard bag weight, effectively reducing material waste and unqualified products.
• High Packaging Efficiency:Optimized impeller feeding and fast filling structure, with stable continuous operation capacity. It greatly improves packaging speed and production throughput, effectively reducing manual labor intensity and production costs.
• Dust-Free & Eco-Friendly Operation:Built-in negative pressure dust removal interface and fully sealed filling structure, which effectively suppresses powder overflow during packaging. It improves workshop working environment and complies with international environmental protection emission standards.
• Intelligent & Easy Operation:Adopts PLC + touch screen integrated control system. Workers can set packaging weight, operating speed and other parameters visually. It supports automatic fault detection and alarm, with simple operation and stable running logic.
• Strong Material Compatibility:Suitable for all kinds of dry powdery building materials, including cement, ordinary dry mortar, tile adhesive, wall putty powder, thermal insulation mortar and mineral powder, with wide application range and strong universality.
• Durable & Stable Structure:The whole machine is made of thickened carbon steel, with wear-resistant treatment on feeding impeller and material channel. It features anti-abrasion, anti-corrosion and long service life, adapting to long-term continuous industrial operation.
• Low Maintenance Cost:Modular assembly design with standardized wearing parts. The structure is simple and reasonable, convenient for daily cleaning, inspection and parts replacement, greatly reducing later maintenance time and cost.

• Complete comprehensive pre-start inspection before operation. Check the tightness of machine fasteners, the flexibility of pneumatic components, the integrity of dust removal device and the sensitivity of weighing sensors. Remove foreign impurities inside the machine to avoid jamming and equipment failure.
• Ensure stable and dry compressed air supply. Filter moisture and impurities in the air source regularly to prevent pneumatic valve and cylinder failure, which may affect packaging accuracy.
• Set the standard packaging weight through the touch screen according to production requirements. Professional staff shall complete weight calibration regularly. It is forbidden for untrained personnel to modify system internal parameters arbitrarily.
• Keep raw materials clean and dry without hard blocks, sundries and large particles, so as to prevent blockage of the feeding nozzle and damage to the impeller structure.
• Operators must receive professional operation training before taking duty. Wear dust-proof masks and protective gloves during work. It is strictly prohibited to open protective covers or touch running parts during machine operation.
• Standard startup and shutdown procedures must be followed. Start the dust removal system first, then start the main machine for no-load pre-operation. Stop feeding first before shutdown, and stop the main machine after all materials are discharged completely.
• Clean residual powder and accumulated materials inside the machine thoroughly after daily work to avoid material caking, which will affect the next day’s packaging accuracy and filling smoothness.
• Carry out regular maintenance, including lubricating transmission parts, checking circuit stability and replacing worn nozzles and sealing parts. Cut off power and air supply completely before maintenance and overhaul.
• The production workshop shall be kept dry, ventilated and flat. Long-term humid environment is prohibited to prevent material moisture caking and internal electrical component damage.

• Dry Mortar Production Lines: Professional packaging for tile adhesive, plastering mortar, masonry mortar, waterproof mortar, self-leveling mortar and other dry-mixed products.
• Cement Plants & Cement Stations: Quantitative packaging of ordinary cement, composite cement and other cementitious powder materials.
• Building Material Factories: Suitable for packaging wall putty powder, mineral powder, building binder powder and other decorative building materials.
• Large Industrial Parks: Supporting continuous and automatic packaging production for large-scale building material batch production projects.
• New Material Enterprises: Applied for packaging various modified powder building materials and functional mortar products.

• Q1: What kind of packaging bags does this machine support? A1: This machine is specially designed for standard valve-port paper bags, which is the mainstream bag type for cement and dry mortar products. It does not support open-mouth bags without structural modification.
• Q2: What causes large weighing errors during packaging? A2: Common reasons include inaccurate sensor calibration, unstable air pressure, material bridging and caking in the silo, worn filling nozzle, or abnormal dust removal negative pressure. Recalibrate the weighing system, clean blocked materials and check pneumatic system to solve the problem.
• Q3: Can the machine pack different mortars such as tile adhesive and putty powder alternately? A3: Yes. The machine has strong material compatibility. When switching different products, thoroughly clean the silo, feeding pipeline and nozzle to avoid cross-contamination of different mortar formulas.
• Q4: How to solve serious dust overflow during working? A4: Check whether the matching dust collector works normally, ensure stable negative pressure, replace aging sealing gaskets, and check the tightness of the filling nozzle to effectively reduce dust leakage.
• Q5: How many workers are required for normal operation? A5: Only 1–2 workers are needed for bag sleeving and finished bag collection. The whole processes of quantitative filling, weighing and bag dropping are completed automatically by the machine.
• Q6: How to deal with nozzle blockage? A6: Immediately stop feeding and cut off power and air supply. Manually clean the caked materials inside the nozzle and impeller. Never clean the machine during operation to avoid safety accidents.
• Q7: What is the daily maintenance focus? A7: Daily maintenance focuses on cleaning residual powder, checking wearing parts and air pressure stability, calibrating weighing accuracy, and lubricating transmission components. Regular maintenance can ensure stable operation and extend equipment service life.
