The open mouth bagging machine is a special automatic quantitative packaging equipment tailored for dry mix mortar production lines. It is mainly used for quantitative weighing, filling, conveying and sealing of powdery and granular materials such as dry mix mortar, putty powder, gypsum powder and building admixtures. Adopting screw or gravity feeding and high-precision sensor weighing system, the equipment realizes automatic bag clamping, continuous filling, accurate metering and automatic bag delivery for open-mouth woven bags, paper-plastic bags and kraft paper bags.
Matching perfectly with dry mortar mixing systems and conveyor sewing equipment, it realizes streamlined packaging operation from finished material storage to finished bag products. It effectively solves the problems of low manual packaging efficiency, large weighing error and serious dust overflow, greatly improves the finished product packaging standardization of mortar factories, and is an indispensable core supporting equipment for automated dry mix mortar production lines.
Equipped with high-sensitivity load cell weighing sensors and intelligent microcomputer weighing controller. It supports dynamic real-time weighing and automatic fine feeding correction. The weighing error is controlled within ±0.5%, ensuring uniform net weight of each bag of mortar materials and consistent product quality.
The optimized feeding structure and mechanical bag clamping mechanism enable continuous circulating bagging. It cooperates with automatic conveyor and bag sewing machine to complete filling, conveying and sealing in one process. The packaging speed is stable and efficient, which fully meets the continuous production demand of large-scale dry mix mortar factories.
A reserved dust removal interface is designed at the filling port, which can be connected with the centralized dust removal system of the mortar production line. It effectively absorbs floating dust generated during material filling, avoids dust diffusion in the workshop, reduces material waste, and meets environmental protection production standards.
Adopts PLC + touch screen integrated control system, with simple and intuitive operation. Users can freely set packaging weight, feeding speed and delay parameters, and store multiple parameter formulas. The equipment is compatible with various common open-mouth packaging bags and suitable for multiple types of mortar powder materials.
The whole machine adopts thickened steel frame and anti-wear feeding structure, with stable operation and low failure rate. Key vulnerable parts are standardized and modularized, which are convenient for quick disassembly, replacement and daily maintenance, effectively reducing later operation and maintenance costs.
Built-in bag missing detection, overload alarm, material blockage protection and emergency stop functions. The equipment will automatically alarm and stop working in case of abnormal conditions to prevent material overflow, equipment damage and operational safety accidents.

Check the power supply, air pressure circuit and mechanical fastening parts before starting the machine. Ensure there are no foreign objects or material blockages inside the feeding barrel and filling nozzle. Calibrate the weighing system regularly to ensure metering accuracy. Verify that all safety protection devices and emergency stop buttons are in normal working condition.
Only qualified dry powdery materials can be put into use; hard blocks, iron impurities and foreign sundries are strictly prohibited from entering the equipment to avoid damage to the screw and weighing structure. Place the open-mouth bag stably on the bag clamping position. It is strictly forbidden to stretch hands or tools into the filling port during equipment operation.
Observe the equipment operation status in real time during working. Once abnormal noise, severe vibration, material leakage, overweight or underweight alarm occurs, press the emergency stop button immediately to shut down and troubleshoot. It is forbidden to modify system parameters and weighing data arbitrarily during normal operation. Keep the dust removal pipeline unobstructed to ensure dust collection effect.
After daily shutdown, thoroughly clean the residual mortar powder in the hopper, feeding screw and filling nozzle to prevent material caking and blockage. Regularly lubricate transmission bearings and moving parts. Check the wear of screw blades, sealing rings and bag clamping components, and replace vulnerable parts in a timely manner. Clean the dust filter accessories regularly to maintain stable equipment performance.
Operators must receive professional operation training before taking post and wear corresponding labor protection supplies. Keep the electrical control box dry and ventilated to avoid electric leakage and short circuit. Cut off the power supply and air source completely during equipment maintenance and overhaul to ensure construction safety.
If the equipment is shut down for a long time, completely clean all residual materials, do a good job of rust prevention and moisture-proof treatment for metal parts and electrical components, and cover the equipment with dust-proof protective tools.
Special packaging equipment for automatic production lines of masonry mortar, plastering mortar, tile adhesive, anti-crack mortar and thermal insulation mortar, realizing standardized finished product packaging.
Suitable for quantitative packaging of putty powder, gypsum powder, cement powder, mineral powder and various building powder admixtures.
Applicable for packaging of non-corrosive dry powdery materials with good fluidity, meeting the packaging needs of various industrial powder products.
Support on-site centralized mortar production and automatic bagging for large engineering projects, improving on-site construction efficiency and material management standardization.
Matching production and packaging of energy-saving and environment-friendly building materials such as waterproof mortar and thermal insulation mortar, adapting to green building production standards.
A1: It is mainly applicable to dry powdery materials such as all kinds of dry mix mortar, putty powder and gypsum powder. It matches all conventional open-mouth packaging bags including woven bags, paper-plastic composite bags and kraft paper bags, not applicable for valve bags.
A2: Yes. The packaging weight can be freely set within the standard 20–50kg range via the touch screen. The feeding speed and packaging cycle can also be adjusted according to material fluidity and production demands to achieve optimal packaging efficiency.
A3: Common reasons include uncalibrated weighing system, unstable material fluidity, blocked feeding screw, damaged sensor or loose mechanical parts. Regular calibration, residual material cleaning and equipment inspection can effectively solve weighing deviation problems.
A4: The machine is designed with a special dust removal interface. When connected with the mortar line’s dust collector, it can effectively suppress flying dust with almost no dust overflow. Without dust removal equipment, a small amount of floating dust will be generated during high-speed filling.
A5: The equipment adopts intelligent touch screen control with simple operation logic. Ordinary workers can master daily operation, parameter setting and start-stop work after simple training. Professional maintenance personnel are only required for equipment calibration and fault maintenance.
A6: It supports both independent stand-alone operation and integrated matching with full dry mix mortar production lines. It can be equipped with a separate storage silo for independent packaging work, with strong flexibility.
A7: The main vulnerable parts include screw blades, sealing rings, bag clamping accessories and sewing machine needles. All parts are standard accessories with low cost and convenient replacement, bringing low daily operation cost.
