valve bag packing machine

The valve bag packing machine is a professional automatic quantitative packaging unit specially configured for dry mixed mortar production lines. Designed for valve-port bag packaging, it is dedicated to dust-free, high-precision filling of dry powdery and fine granular building materials. Common applicable materials include ordinary dry mixed mortar, tile adhesive, wall putty, gypsum powder, waterproof mortar and thermal insulation mortar.

Equipped with industrial-grade weighing sensors and intelligent microcomputer controller, the machine adopts dual-speed coarse and fine feeding control. The weighing error is strictly controlled within ±0.5%. Fixed weight parameters can be stored and recalled with one click, ensuring uniform net weight of each mortar bag and standardized finished product quality.

Unique closed valve-port filling design avoids material splashing and floating dust overflow during packaging. Reserved dust removal interface can be connected with the plant’s centralized dust removal system, realizing almost zero-dust operation. It effectively reduces material waste, improves workshop working environment and meets strict environmental protection production standards.

Optional pneumatic, impeller and screw feeding structures adapt to different fluidity mortar materials, from coarse ordinary mortar powder to superfine putty powder. It solves common problems such as material blockage, uneven feeding and unstable weighing of traditional packaging machines.

Adopts PLC + touch screen intelligent control system. The whole process including automatic induction filling, quantitative material stopping and automatic bag dropping is unmanned except simple manual bag sleeving. Multiple product formulas can be stored for fast switching, greatly reducing labor intensity and production cost.

The machine features compact layout, small floor space and flexible installation. It can be used independently or perfectly integrated into full-automatic dry mortar production lines, seamlessly docking with automated pallet conveyors and palletizing systems to realize full-process intelligent production.

Key contact parts are made of wear-resistant materials. The whole machine adopts thickened steel frame with stable operation and low failure rate. All vulnerable parts are standard universal accessories with low replacement cost and convenient daily maintenance, ensuring long-term stable and low-cost operation.

Built-in bag-missing detection, overload protection, blockage alarm and emergency stop functions. The equipment automatically alarms and stops under abnormal conditions to avoid material overflow, equipment damage and safety accidents, ensuring safe and standardized production.

Before startup, fully inspect the power supply, pneumatic system, transmission components and weighing sensors. Remove foreign sundries and accumulated powder inside the feeding cavity and filling nozzle. Calibrate the weighing system regularly to ensure accurate metering. Confirm all safety protection devices and emergency stop functions work normally.

Use qualified standard valve bags; damaged or deformed bags are prohibited. Ensure stable and firm bag sleeving to avoid bag falling during filling. It is forbidden to put hands or tools near the filling nozzle during operation. Hard impurities and iron blocks are strictly prohibited from entering the machine to prevent equipment jamming and damage.

Monitor equipment running status continuously during production. Stop the machine immediately for troubleshooting in case of abnormal noise, vibration, material leakage, blockage or inaccurate weighing. Do not modify system parameters and formula data arbitrarily during normal operation. Keep the dust removal pipeline unobstructed.

Clean residual powder inside the feeding system and filling mouth thoroughly after daily shutdown to prevent material caking and blockage. Regularly lubricate transmission bearings and movable parts. Inspect the wear of internal blades, sealing rings and vulnerable parts, and replace damaged accessories timely. Clean dust removal accessories periodically to maintain stable dust removal effect.

All operators must complete professional pre-job training and wear standard labor protection equipment. Keep the electric control cabinet dry and ventilated to avoid electric leakage and short circuit faults. Completely cut off power and air sources before equipment maintenance and overhaul.

For long-term shutdown, thoroughly clean all residual materials inside the machine. Perform professional rust-proof, moisture-proof and dust-proof treatment on mechanical and electrical components to extend equipment service life.

Standard supporting packaging equipment for intelligent dry mortar plants, used for quantitative packaging of masonry mortar, plastering mortar, tile adhesive, anti-crack mortar, self-leveling mortar and thermal insulation mortar.

Suitable for dust-free and closed production workshops, meeting high environmental protection standards and solving the dust pollution problem of traditional open-mouth packaging machines.

Ideal for packaging superfine putty powder, high-grade gypsum powder, fine bonding mortar and other easy-dusting fine powder materials with high packaging requirements.

Adapt to high-volume and continuous packaging operation of large mortar production bases, supporting high-efficiency mass production and standardized finished product stacking.

Perfectly matched with automated pallet conveyors and palletizers to form an integrated packaging and palletizing production line, realizing full-process unmanned intelligent logistics operation.
