Solutions to common problems of food packaging machines?

Food packaging machine refers to machinery that can complete all or part of the product and food packaging process. The packaging process includes main processes such as filling, wrapping, and sealing, as well as related pre- and post-processes, such as cleaning, stacking, and disassembly. In addition, packaging also includes processes such as metering or stamping on the package. The use of mechanical packaging products can improve productivity, reduce labor intensity, meet the needs of large-scale production, and meet the requirements of cleanliness.

1. What is the reason for the slow heating of the shrinking machine or the inability to rise to a higher temperature (above 160 degrees Celsius)?

The line of the heater is that the main power line passes through a magnetic switch and then to the electric heating tube, so it should be checked whether the contacts of the magnetic switch are normal. If the line does not pass through one of the phases, the above phenomenon will occur. If the magnetic switch is normal, you can check the meter again to see if the ohm value of each phase is the same as that of the machine. If it is normal, it should be a short circuit. If all phases are connected but the circuit or electric heating tube is still abnormal, the heater needs to be replaced.

2. How to adjust the film material that is easy to shift and cannot be fed normally when the equipment is working?

If the film material is offset in the equipment, and the adjustment of the film roll position and the tension balance bar is ineffective, this problem can be solved by adjusting the angle of the upper triangle plate. If the upper film material deviates from the clamping chain, the upper triangle plate can be adjusted clockwise; the lower film material deviates from the clamping chain, and the upper triangle plate can be adjusted counterclockwise.​​

Common troubleshooting methods and steps of vacuum packaging machine:

1: The pump oil is polluted, too little or too thin Clean the vacuum pump and replace it with new vacuum pump oil;

2. The extraction time is too short. Extend the extraction time. The extraction filter is blocked. Clean or replace the exhaust filter.

3. If there is air leakage, turn off the power after evacuation, and check the solenoid valve, pipe joint, vacuum pump suction valve and the sealing gasket around the studio for air leakage.​​

4. The O-ring of the suction valve falls off, pull out the vacuum tube on the pump nozzle, remove the suction nozzle, take out the compression spring and the suction valve, gently stretch the O-ring several times, re-insert it into the groove, and then It can be installed; if the rotary vane is worn out, replace the rotary vane.​​

5. The oil return valve is blocked. Remove the oil return valve and clean it (see the manual for details). The oil window is loose. After draining the oil, remove the oil window and wrap it with raw material tape or thin plastic film.​​

6. The suction filter is blocked or polluted. Clean or replace the exhaust filter; if the pump oil is polluted, replace it with new oil; if the oil return valve is blocked, clean the oil return valve.

7. If the heating strip is burned out, replace the heating strip; if the heating time relay is burned out, replace the time relay; if the heating wire is burned out, replace the heating wire and install it firmly; if the switch for controlling the heating temperature band is in poor contact, repair or replace it; Repair without reset (blow off foreign objects with airflow) or replace; heating transformer is damaged and replaced

8. The heating time relay is in poor contact or burned out, adjust the time relay to contact or replace the socket; the control heating AC contactor does not reset, repair or replace

9. The heating time and heating temperature are not adjusted properly; there are attachments on the heating cloth, gently scrape the attachments with a fingernail; the pressure solenoid valve does not move to clean or replace the solenoid valve; the airbag is damaged and the airbag is replaced; the pressurized trachea is damaged Repair or replace; the cooling time relay is broken without air release (in the electrical box) Replace the time relay; the air release valve circuit is broken and found and connected; the air release valve is stuck or burned out, remove it for cleaning or replace it
