open mouth bag packing machine

The open mouth bag packing machine is professional supporting packaging equipment specially designed and matched for dry mortar production lines. It is mainly used for quantitative weighing and automatic filling of powdered and granular building materials such as dry mortar, cement powder, fly ash, putty powder and tile adhesive. Adopting advanced suspended electronic weighing structure and dual-speed feeding control technology, the machine realizes automated procedures including bag clamping, quantitative filling, material buffering, bag releasing and conveyor output. Equipped with built-in arch breaking and dust removal interface, it effectively solves material bridging, blocking and dust overflow problems during powder packaging. Featuring semi-automatic operation mode with manual bagging and automatic metering filling, it is simple, stable and highly adaptable. It can perfectly connect with finished product silos and twin paddle mixers, becoming the standard packaging equipment for medium and large dry mortar production factories.

• High Weighing Precision & Stable Performance:Adopts high-precision weighing sensors and intelligent PLC weighing controller, with fast and slow dual-stage feeding. The weighing error is stably controlled within ±0.2%~±0.5%, ensuring uniform weight of each bag of mortar materials, effectively avoiding material waste and unqualified products.
• Dust-free & Environment-friendly Packaging:The fully sealed filling nozzle matches the supporting dust removal system interface, which can effectively collect overflowing powder during packaging. It realizes low-dust and clean operation, fully meeting factory environmental protection emission standards and improving workshop working environment.
• Anti-blocking & Continuous Feeding:Equipped with mechanical vibration arch breaking device inside the hopper, which can effectively break material bridging and caking caused by fine powder and fiber mortar, ensuring smooth and continuous material feeding without blockage.
• Wide Material & Bag Adaptability:It is compatible with all kinds of dry powder mortars and building powder materials, and supports multiple open-mouth packaging bags including PP woven bags, kraft paper bags and composite bags. It can be matched with conveyor and automatic bag sewing machine to form an integrated packaging station.
• Simple Operation & Labor Saving:Comes with English touch screen control system, intuitive operation and simple parameter adjustment. Only manual bag sleeving is required, while weighing, filling and bag dropping are fully automatic, greatly reducing manual labor intensity and improving packaging efficiency.
• Durable Structure & Low Maintenance:The whole machine adopts thickened carbon steel frame, and the material contact parts are made of wear-resistant materials. The modular structural design is convenient for daily cleaning, maintenance and replacement of vulnerable parts, with low failure rate and long service life.

• Complete pre-operation inspection before startup. Check the air pressure stability, sensor connection status, hopper interior cleanliness and sealing tightness. Remove all hard foreign objects inside the equipment to avoid mechanical damage. Never start the machine without calibration or with faulty parts.
• Follow standard operating procedures strictly. Only use qualified open-mouth bags and ensure the bag mouth is firmly clamped to prevent material leakage and dust overflow. Do not strike or shake the weighing frame and sensors during operation to avoid weighing deviation.
• Strictly abide by safety operation specifications. It is forbidden to place hands or tools under the filling nozzle and bag clamping mechanism during equipment operation. Immediately stop the machine and cut off the power once abnormal noise, vibration, excessive weighing error or material blockage occurs.
• Perform thorough cleaning after each working shift. Clean residual mortar powder and condensed materials inside the hopper and filling nozzle to prevent material moisture absorption, solidification and blockage, which may affect subsequent packaging accuracy and equipment operation.
• Carry out regular maintenance and calibration. Calibrate the weighing system periodically to ensure metering accuracy. Inspect pneumatic components, sealing parts and conveyor accessories regularly, and replace aging and worn parts in time.
• Keep the electrical control cabinet dry and dust-proof. Non-professional personnel are prohibited from disassembling electrical and control components without permission. Cut off the total power supply completely during equipment maintenance and overhaul.
• Ensure the supporting dust removal system operates normally during production. The equipment shall be installed on flat and hardened ground to keep the whole machine stable, avoiding operation in high humidity and harsh dusty environment for a long time.

• Dry Mortar Production Line Supporting:Special matching packaging equipment for fully automatic and semi-automatic dry mortar production lines, used for finished product packaging after mortar mixing and storage.
• Ordinary Construction Mortar Packaging:Suitable for quantitative packaging of masonry mortar, plastering mortar, bonding mortar and finishing mortar for construction and municipal projects.
• Special Functional Mortar Packaging:Widely used for packaging waterproof mortar, thermal insulation mortar, anti-crack mortar, self-leveling mortar, repair mortar and fiber modified mortar.
• Building Powder Material Processing:Applicable for packaging tile adhesive, wall putty powder, dry powder coating, gypsum powder, joint grout and various inorganic powder building materials.
• Industrial Batch Production:Ideal for standardized packaging operations in building material factories, mortar processing plants and large-scale powder production bases.
