Programmable quantitative sealing machineIt is an efficient device that achieves precise sealing through program control, widely used in industries such as food, medicine, and daily chemical. This guide provides full process guidance from pre operation preparation, equipment setup, operation monitoring to maintenance, ensuring safe and efficient use.

1、 Preparation before operation: Ensure that the equipment and materials are compatible

Equipment inspection

Power and grounding: Confirm that the equipment is connected to a 220V/50Hz power supply, and the three core grounding wire is firmly connected to avoid the risk of leakage.

Sealing component inspection: Check whether the heating strip (such as silicone strip, PTFE coated strip) is intact, without cracks or aging; The sealing mold (such as customized grooves) matches the size of the packaging material.

Air source connection (if required): If the equipment is equipped with a pneumatic compression device, check if the air pipe connection is tight and adjust the air pressure to 0.4-0.6MPa.

Material preparation

Packaging material selection: Choose compatible materials based on material characteristics (such as aluminum foil composite film, PE/PP plastic film), with a recommended thickness of 0.08-0.3mm.

Material filling: Ensure that the amount of material inside the packaging meets the design range (such as a solid particle filling error of ≤± 2%), and avoid expansion or leakage during sealing.

Environmental Requirements

Temperature: 10-35 ℃ (to avoid material deformation caused by high temperature); Humidity: ≤ 70% (to prevent electrical components from getting damp).

The workbench is flat and free from interference from vibration sources.

2、 Equipment settings: Accurate parameter matching requirements

Program selection and editing

Preset program call: Select a stored program (such as "drug aluminum foil sealing" or "food plastic bag sealing") through the touch screen.

Custom program settings:

Temperature: Set according to the melting point of the material (e.g. PE film 120-140 ℃, aluminum foil composite film 160-180 ℃).

Time: Sealing time 0.5-3 seconds (short time for thin materials, long time for thick materials).

Pressure: Pneumatic compression pressure of 0.2-0.5MPa (low pressure for soft materials, high pressure for hard materials).

Cooling time: Cool for 0.5-2 seconds after sealing to prevent material adhesion.

Installation of sealing mold

Loosen the fixing screws of the mold, align the customized mold (such as circular or square grooves) with the heating bar position, tighten the screws and test the flatness of the press fit.

parameter calibration

Use standard samples (such as 0.1mm thick PE film) for sealing, check the sealing strength (tensile force ≥ 5N/15mm width) and sealing performance (no bubbles or leakage).

Adjust the parameters to the qualified range and save the program.

3、 Operation: Standardize processes to prevent risks

Startup steps

Turn on the power switch and perform a self-test on the device (displaying "standby" status).

Place packaging materials at the feeding port, ensuring alignment with the sealing line.

Press the 'Start' button, and the device will automatically complete the sealing, cooling, and discharging processes.

operation monitoring

Temperature monitoring: Real time display of heating strip temperature through infrared sensors, automatic alarm and pause when exceeding the limit (such as ± 5 ℃).

Sealing quality inspection: 3-5 samples are randomly selected from each batch to check the width of the sealing line (recommended 2-5mm) and ensure there are no wrinkles or burns.

Exception handling:

Poor sealing: Increase temperature or pressure and check if the heating strip is oxidized.

Material card machine: Stop immediately and clean the residue at the feed inlet.

Alarm code: Refer to the manual (e.g. E01 indicates a temperature sensor malfunction and needs to be replaced).

Shutdown operation

After sealing, press the "stop" button to enter standby mode of the device.

Turn off the power switch and disconnect the air source (if applicable).

Clean the sealing mold and heating strip residue to prevent adhesion.

4、 Maintenance and upkeep: Extend equipment lifespan

Daily cleaning

After sealing, wipe the heating strip and mold with a soft cloth to avoid residue carbonization.

Clean the debris at the inlet and outlet to prevent blockage.

Weekly maintenance

Check if the connecting wire of the heating strip is loose, and use a multimeter to test the resistance value (refer to the equipment manual for the normal range).

Lubricate pneumatic components (such as cylinder pistons) using specialized lubricating oil.

Monthly maintenance

Replace the aging heating strip (such as blackening or cracking on the surface).

Verify the accuracy of the temperature sensor (± 2 ℃), and replace it if it exceeds the tolerance.

Check the sensitivity of the touch screen and clean the touch panel.

Annual major overhaul

Disassemble the equipment, clean the internal dust, and check if the solder joints on the circuit board have fallen off.

Replace vulnerable parts such as sealing rings and O-rings.

Conduct safety testing on the equipment (such as insulation resistance ≥ 1M Ω).

5、 Safety precautions: Avoid operational risks

personal protection

Wear insulated gloves (to prevent burns from heating strips) and goggles (to prevent debris splashing) during operation.

Long hair should be tied up to avoid getting caught up in transmission components.

Equipment safety

Do not touch the heating strip or mold while the device is running.

Modifying parameters requires stopping the operation to avoid accidental triggering that may cause parameter mutations.

If any odor, abnormal noise or smoke is detected, immediately stop the machine and cut off the power for inspection.

emergency response

Fire: Cut off the power supply, use dry powder fire extinguishers to extinguish the fire, and strictly prohibit using water.

Electric shock: Use an insulated rod to open the wire, perform cardiopulmonary resuscitation on the injured person, and call 120.

Mechanical stuck: Press the emergency stop button, manually release the pressure, and perform maintenance.
