Food packaging machines refer to machinery that can complete all or part of the product and food packaging process. The packing 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 measuring or stamping on the package. The use of mechanical packaging products can increase productivity, reduce labor intensity, meet the needs of large-scale production, and meet the requirements of cleanliness and sanitation.

1. What is the reason why the shrinking machine heats up slowly or cannot rise to a higher temperature (above 160 degrees Celsius)?

The circuit of the heater is that the main power line goes through a magnetic switch and then to the electric heating tube, so it is necessary to check 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 ammeter again to see if the ohm value of each phase is the same as that of the machine. If 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. When the equipment is working, the membrane material is easy to shift and cannot be fed normally. How to adjust?

If the film material is offset in the equipment, and the adjusted position of the film roll and the tension balance bar are invalid, the problem can be solved by adjusting the angle of the upper triangular plate. If the upper film material deviates from the clamping chain, the upper triangular plate can be adjusted clockwise; if the lower film material deviates from the clamping chain, the upper triangular plate can be adjusted counterclockwise. the

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 with new vacuum pump oil;

2. The exhaust time is too short, extend the exhaust time; the exhaust filter is blocked, clean or replace the exhaust filter;

3. If there is an air leak, turn off the power after evacuating, and check whether there is any air leak in the solenoid valve, pipe joint, suction valve of the vacuum pump and the gasket around the working room. the

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

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. the

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

7. If the heating strip is burnt out, replace the heating strip; if the heating time relay is burnt out, replace the time relay; if the heating wire is blown 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; for the AC contactor that controls heating Repair without reset (blow off foreign objects with airflow) or replace; if the heating transformer is damaged, replace it

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

9. The heating time and heating temperature have not been adjusted properly; there are attachments on the heating cloth and gently scrape off the attachments with your nails; the pressurized solenoid valve does not operate to clean or replace the solenoid valve; the airbag is damaged and the airbag is replaced; the pressurized air pipe is damaged Repair or replace; the cooling time relay is broken without deflation (in the electrical box) Replace the time relay; the circuit of the deflation valve is broken, find and connect it; the deflation valve is stuck or burnt out, removed, cleaned or replaced
