How to solve the common problems of vacuum packaging machine
How to solve the common problems of vacuum packaging machine
1. Low vacuum, pump oil pollution, too little or too thin, clean the vacuum pump, replace with new vacuum pump oil, The pumping time is too short, extend the pumping time, the suction filter is blocked, clean or replace the exhaust filter, if there is a leak, turn off the power after pumping down, check the solenoid valve, pipe joints, vacuum pump suction valve and the surrounding of the studio Whether the gasket is leaking.
2. Loud noise. The vacuum pump coupling is worn or broken and replaced, the exhaust filter is blocked or the installation position is incorrect, clean or replace the exhaust filter and install it correctly, check the solenoid valve for leaks and eliminate them.
3. Vacuum pump oily smoke. The suction filter is blocked or contaminated. Clean or replace the exhaust filter. The pump oil is contaminated. Replace with new oil. The oil return valve is blocked. Clean the oil return valve.
4. No heating. The heating bar is burned out, replace the heating bar, and the heating time relay is burned out (the two lights are on at the same time when the machine is turned on, and the OMRON light is yellow). Replace the time relay, the heating wire is burned, replace the heating wire, and install it firmly to control the heating temperature The band switch is in poor contact, repair or replace, the AC contactor that controls the heating is not reset, repair (blow off foreign objects with airflow) or replace, and the heating transformer is broken and replaced.
5. Heating does not stop. If the heating time relay is in poor contact or burned out, adjust the time relay to contact or replace the socket, and control the heating AC contactor not to reset, repair or replace.
6. The vacuum pump sprays oil, the O-ring of the suction valve falls off and pulls out the pump nozzle Remove the suction nozzle, take out the compression spring and suction valve, gently stretch the O-ring several times, reinsert it into the groove, and install it again. The rotor is worn out and the rotor is replaced.
7. The vacuum pump leaks oil. If the oil return valve is blocked, remove the oil return valve and clean it (see instructions 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 packaging machine market has unlimited business opportunities
With the development of the times, China’s packaging industry is also constantly changing , Packaging machine equipment is gradually developing towards standardization and regularization. Especially in recent years, the domestic packaging machine industry has made considerable progress. The company continues to grow and expand, and the production demand is gradually expanding. This all depends on the characteristics of high production efficiency, high degree of automation, and complete supporting equipment of the new packaging machine. The future packaging machine equipment will also cooperate with the industry's automation development trend, so that the packaging machine equipment has a better development.
When considering the pricing of VFFS machines, it is necessary to see more than just the purchase price. The appropriate investment provides reliable performance, efficiency and long-term value, rather than a reduced price.
The selection of the appropriate sauce pouch packing machine is a matter of matching your product, the type of pouch and your production objectives. The right system enhances efficiency, less wastage and uniformity in performance.
Operating a noodles packing machine successfully requires consistent preparation, correct parameter control, and disciplined quality checks. However, long-term stable output also depends on choosing equipment built for speed, accuracy, and fragile product handling.
