Four-lanes liquid Packing Machine manufacturer

Confirm that all fasteners (screws, nuts) are tight and that the drive belt/chain tension is appropriate.

Check the lubrication system and add lubricating oil to the guide rails, bearings, etc., as required by the instruction manual.

Clean the hopper, pipes, and filling head to ensure there is no residual material or impurities.

The packaging film (roll film) must meet specifications (width, thickness, material). Pay attention to tension adjustment during installation to prevent film misalignment or breakage.

Confirm that the viscosity, pH, temperature, and other parameters of the liquid material meet the equipment requirements (especially for corrosive liquids, a corrosion-resistant filling system must be selected).

Check that the protective cover, emergency stop button, safety door, and other safety devices are intact and effective.

Ensure the equipment is properly grounded to prevent static electricity or leakage.

Precisely adjust parameters such as filling volume, heat sealing temperature, and cutter position according to the packaging specifications (capacity, speed). Initial operation requires trial packaging to test sealing and filling accuracy.

Pay attention to temperature control: Too low a sealing temperature may result in a weak seal, while too high a temperature may burn through the film material.

Observe the filling head for leaks; if any are found, adjust the valves or clean the seals.

Monitor liquid level stability and maintain constant pressure in the feeding system (if using a pump).

Ensure the packaging film is flat and wrinkle-free on the forming device, with accurate photoelectric tracking (color mark) to avoid pattern misalignment.

Adjust the film pulling mechanism to synchronize the film feeding speed with the filling rhythm, preventing excessive or insufficient film pulling.

Regularly check for uniform sealing, absence of air bubbles, and neat edges. Adjust heat sealing pressure and time.

Promptly clean residual film debris from the cutter to prevent jamming or product contamination.

Thoroughly clean the hopper, pipes, and filling nozzles to prevent material condensation and blockage (especially for syrups and oily liquids).

Clean the heat-sealing block, cutter, and other components to prevent adhesion that could affect the seal.

Drain condensate from the air lines (if using pneumatic components).

Check the operating status of pneumatic/hydraulic components such as pumps, cylinders, and solenoid valves.

Calibrate the metering system (e.g., peristaltic pump, servo filling) to ensure filling accuracy.

Lubricate and maintain transmission components (gears, bearings).

Check for air bubbles or sediment in the material; adjust the liquid temperature or stirring speed.

Check the sealing of the metering pump or valves; replace worn parts.

Adjust the heat-sealing temperature, pressure, and time; ensure the sealing area is clean.

Check the suitability of the packaging film material (e.g., heat resistance, composite layer uniformity).

Immediately stop the liquid packing machine and inspect it. It may be due to loose mechanical parts, damaged bearings, or transmission misalignment.

Must be professionally trained and familiar with the equipment's emergency stop, manual operation, and other basic functions.

Long hair and loose clothing must be tied up to avoid getting caught in transmission parts.

Never reach into the forming or cutting area while the machine is running.

Non-professionals should not disassemble the electrical cabinet. Power and gas must be disconnected during maintenance.

High-temperature components (heat-sealing blocks) must be cooled before contact to prevent burns.

Corrosive and flammable liquids require explosion-proof and leak-proof measures, and equipment made of corresponding corrosion-resistant materials (such as 316L stainless steel, food-grade silicone tubing).

Keep the workshop environment dry and clean to avoid dust affecting the sensitivity of photoelectric sensors.

Record daily operating parameters, fault conditions, and maintenance details for traceability and optimization.
