cement bag packing machine

The cement bag packing machine is a fully automatic quantitative powder packaging device, specially customized for dry mortar and cement production supporting equipment. It is mainly used for quantitative bag filling of various powdery building materials, including cement, tile adhesive, dry mixed plastering mortar, masonry mortar, wall putty powder and waterproof mortar.

Equipped with high-precision weighing sensors and mature PLC control system, the machine realizes automatic bag sleeving, quantitative feeding, precise weighing, automatic bag dropping and fault self-checking. Compared with traditional manual packing equipment, this machine features higher efficiency, stable weighing accuracy and closed dust-proof structure. It effectively solves the problems of large weight deviation, serious dust pollution and high labor cost in traditional packaging work. It is essential standard supporting equipment for standardized and large-scale production of modern dry mortar factories.

• Precise Quantitative Weighing:Adopts high-sensitivity digital weighing sensing module with intelligent weight compensation function. The packaging weight error is strictly controlled within ±0.3kg. It ensures uniform net weight of each bag of mortar and cement products, effectively avoids unqualified products and material waste, and meets international sales weight standards.
• High Packaging Efficiency:Optimized impeller forced feeding structure with fast and stable discharging speed. The continuous hourly packaging capacity reaches 150–300 bags, which greatly improves the overall production efficiency of the dry mortar production line and reduces manual operation pressure.
• Closed Dust Removal & Environmental Protection:Integrated negative pressure dust removal design with fully sealed filling channel. It can effectively absorb floating dust generated during the packaging process, keep the workshop clean, reduce material flying loss, and meet global environmental protection production requirements.
• Intelligent Humanized Operation:Adopts PLC + touch screen integrated intelligent control system. All parameters such as packaging weight and running speed can be set and adjusted intuitively. It supports automatic alarm for abnormal weighing, blockage and equipment faults, with simple operation and low technical threshold for workers.
• Wide Material Adaptability:Compatible with all kinds of dry powdery building materials produced by dry mortar production lines, including tile adhesive, cement, putty powder, thermal insulation mortar, repair mortar and mineral powder. It supports multi-product switching production with strong versatility.
• Sturdy & Wear-resistant Structure:The whole machine adopts thickened carbon steel welding structure. The feeding impeller and material contact parts are specially treated with wear resistance and anti-corrosion. It can adapt to long-term uninterrupted industrial operation with low failure rate and long service life.
• Low Operation & Maintenance Cost:Modular integrated design with standardized general wearing parts. The internal structure is simple and reasonable, convenient for daily cleaning of residual materials and quick replacement of accessories, which greatly reduces daily maintenance time and later operating costs.

• Perform a full pre-operation inspection before startup. Check the firmness of machine fasteners, the flexibility of pneumatic components, the normal operation of dust removal system and the sensitivity of weighing sensors. Remove foreign matters inside the machine to avoid equipment jamming and operational failure.
• Provide stable and dry compressed air for the equipment. Regularly drain water and filter impurities in the air source to prevent pneumatic component failure and ensure stable weighing and packaging accuracy.
• Set the standard packaging weight and operating parameters through the touch screen according to production requirements. Only professional technicians are allowed to calibrate the weighing system; unauthorized modification of internal system parameters is prohibited.
• Ensure that the raw materials such as tile adhesive and cement mortar are dry and free of hard blocks, agglomerations and sundries to prevent blockage of the feeding nozzle and damage to the impeller.
• All operators must receive professional safety and operation training before taking post. Wear dust-proof masks and protective gloves during operation. It is strictly forbidden to open protective covers or touch running components during machine operation.
• Follow the standard startup and shutdown sequence. Start the dust removal system first, then run the main machine with no-load pre-operation. Stop feeding first when shutting down, and turn off the main machine after all materials are completely discharged.
• Thoroughly clean residual powder and accumulated materials inside the machine after daily shutdown to prevent material caking, which may affect the filling smoothness and weighing accuracy of the next operation.
• Carry out regular equipment maintenance, including lubricating transmission parts, detecting circuit stability, and replacing worn nozzles and sealing parts. Cut off all power and air supply before maintenance and overhaul.
• Keep the production workshop dry, ventilated and flat. Long-term humid and dusty environment is prohibited to avoid material moisture caking and damage to electrical components.

• Dry Mortar Production Lines:Special automatic packaging for tile adhesive, plastering mortar, masonry mortar, waterproof mortar, self-leveling mortar and other dry mortar finished products.
• Cement Production Plants & Distribution Stations:Quantitative packaging of ordinary cement, composite cement and other cementitious powder materials.
• Building Material Manufacturing Factories:Suitable for packaging wall putty powder, mineral powder, building adhesive powder and other decorative building powder materials.
• Large Building Material Industrial Parks:Supporting continuous, high-efficiency and standardized packaging operation for large-scale batch production projects.
• New Functional Mortar Enterprises:Applicable for packaging various customized functional dry powder mortars and building powder materials.

• Q1: What kind of bags does the cement bag packing machine support? A1: This machine is specially designed for standard valve-port paper bags, which is the mainstream packaging bag for cement and dry mortar products. It cannot pack open-mouth bags without professional structural modification.
• Q2: What causes unstable weighing and large weight errors? A2: The main causes include uncalibrated weighing system, unstable air pressure, material bridging and caking in the silo, worn filling nozzle, and abnormal dust removal negative pressure. Regular calibration, material cleaning and pneumatic system inspection can solve the problem effectively.
• Q3: Can the machine pack different products like tile adhesive and putty powder alternately? A3: Yes, the machine has strong material compatibility. When switching different mortar products, thoroughly clean the silo, feeding pipeline and nozzle to avoid cross-contamination of different formulas.
• Q4: How to solve serious dust leakage during packaging? A4: Check whether the matching dust collector works normally and maintains stable negative pressure. Replace aging sealing gaskets and check the tightness of the filling nozzle to eliminate dust overflow.
• Q5: How many workers are needed for normal operation? A5: Only 1 to 2 workers are required for bag sleeving and finished bag collection. The whole processes of quantitative filling, precise weighing and automatic bag dropping are completed automatically by the machine.
• Q6: How to handle nozzle blockage during operation? A6: Immediately stop feeding, cut off the power and air supply, then manually clean the caked materials inside the nozzle and impeller. Never clean the machine during operation to avoid safety accidents.
• Q7: What are the key points of daily equipment maintenance? A7: Daily maintenance focuses on cleaning residual powder, checking wearing parts and air pressure stability, calibrating weighing accuracy regularly, and lubricating transmission components. Standard daily maintenance can stabilize operation efficiency and extend equipment service life.
