How to do trouble shooting for VFFS vertical packaging machine

Automatic packaging machines are the most commonly used and indispensable special packaging equipment in the production process in the factory. During long-term operation, if there is the failure and abnormal shutdown, it will cause losses to the manufacturer. For this reason, the user's on-site operators , Maintenance personnel should be familiar with the correct operating procedures of the packaging machine in order to avoid damage of the wrong operation to the machine; At the same time is is a must to know how to regularly maintain and repair the mechanical and electrical parts of the equipment. Users can refer to the common faults of the automatic packaging machine and the corresponding repair solutions to repair the equipment.

Common faults and maintenance solutions of automatic packaging machines

        1. The seal of the horizontal or vertical seal is damaged
Check whether the setting temperature is too high, or the packaging speed is too slow, and the sealing time is too long, which will cause the film to burn. The temperature should not be too high when the sealing is intact. If the sealing part is still not stretched or wrinkled after repeated attempts, the material of the packaging film itself should be considered.

        2. The length of the packaging bag destroys the printed pattern
The cross-sealing cutter is sealed and cut off at the color code to ensure that the packaging film that is too light in the color of the non-color code block is driven to slip. After this situation is eliminated, the photoelectric eye color code recognition sensitivity should be adjusted, and the color code tracking is started in the device function menu. Adjust according to the color code debugging method guided by the technical engineer.
         3. Unable to seal or the seal is not firm
First, rule out whether the horizontal sealing temperature setting is too low, and increase the sealing temperature setting appropriately. If the sealing still leaks, you need to consider abnormal conditions such as solid-state circuit breaker, temperature control module, thermocouple damage, etc., and gradually check and confirm which link has the problem, and timely Replace damaged parts. If the packaging speed is set too fast, it will also cause sealing problems. At this time, the packaging speed should be appropriately reduced.

The packaging machine troubleshooting  

▶Packing machine fault phenomenon Packing equipment fault diagnosis Packing machine repair fault solution

▶There is no response after starting the machine and the machine cannot be turned on. Check whether the emergency stop switch is reset. Reset the emergency stop switch.
Turn off the main power and turn it on again after 20 seconds
▶Leakage switch tripped, heating tube and other electrical equipment leakage, check each electrical appliance one by one
▶The sealing temperature cannot rise up. The power-off protector has tripped. Check and remove the short circuit, then close it again.
▶The heating tube is burned out. Replace the heating tube.
▶The temperature control meter is damaged. Replace the temperature control meter.
▶The temperature of the temperature control meter repeatedly bounces. The thermocouple is loose or damaged. Tighten or replace the thermocouple.
▶The temperature is normal when the machine is stopped but the temperature drops after the machine is turned on. The low voltage causes the power of the heating tube to decrease. Reduce the packaging speed or increase the voltage stabilizing device
▶The power of the heating tube is too small. Replace the high-power heating tube.
▶The seal of the packaging bag leaks and the temperature is not enough. Increase the temperature appropriately
▶Insufficient pressure Check whether the total pressure is 6.5 kg
▶The sealing time is too short Increase the sealing time parameter appropriately
▶The front and rear horizontal sealing rollers are not flat. Carefully adjust the sealing parallelism of the horizontal sealing rollers.
▶Clamping adjust the blanking time or inflation delay
▶Unable to control the cut point or half point. Wrinkles on the edge of the packaging film or optical path quality problems cause photoelectric malfunction. Replace the packaging film.
▶The sensitivity of the photoelectric eye has not been adjusted properly. Re-adjust the photoelectric sensitivity
▶Setting the bag length is not enough to cause the length of the bag. Increase the bag length
▶Abnormal film pulling The pressure of the film transport cylinder is not enough or too large. Check whether the pressure of the film transport is 2.5 kg.
▶Belt slippage or damage Use a saw blade to scrape the surface of the fur belt or replace the belt
▶The packaging film has too much static electricity. Replace the packaging film.

Clear bottles and containers offer consumers a sneak peak at a product, but at the same time create a unique challenge when it comes to packaging. While clear bottles can create a dynamic shelf impact, imagine a product in a clear bottle, on a shelf, in which every single bottle is filled to a different level. The impact might still be termed dynamic, but the effect would likely be the reverse of what was intended. To create an aesthetically pleasing look, the packager must assure that each and every clear bottle is filled to the same level.

While this may sound like an onerous task, the truth is, a filling machine exists to achieve just such a task.

The overflow filling machine uses an overflow principle to ensure that each and every bottle (whether clear or not) will be filled to the same level. This is true even if the bottles do not have the same exact interior volume. For example, a 500 ml (or 16.9 ounce) bottle of water is a fairly common site, whether purchased as a single serving or bought in a pack of 12, 24 or 36. Though they may be termed 500 ml bottles, the interior volume of each 500 ml bottle may actually vary slightly because of the manufacturing process used to make the bottles. The difference will likely not be noticeable to the human eye, but there will be differences. However, using the overflow filler, each of these bottles can still be filled to a consistent level, achieving the intended shelf appearance.

To understand how the overflow filler achieves the level fill, you really need to understand the nozzles used on the overflow machine. Once bottles are in place for the filling to begin, the overflow nozzles will descend and actually enter the bottle. As the nozzles enter the bottle, a foam or rubber seal covers the bottle opening and a spring causes the nozzles to compress. The compression opens the nozzles at the tips and product is released into the bottle. Once the product hits the desired, and pre-set, level, excess product is forced through a return port back to the product supply tank of the filling machine. Once the fill time has elapsed and the excess product has returned to the filling machine supply tank, the seals will release from the bottle opening and the fill nozzles will exit the bottles, leaving each bottle with an even, level fill.

The overflow filler can also work with nearly any level of production, making the machine that much more popular. Overflow fillers can be manufactured as tabletop packaging machines, semi-automatic fillers or even fully automatic filling machines. These machines may be used to fill product on a rotary fill line or an inline packaging system. The overflow filler is truly a versatile piece of packaging equipment, however, it does have its limitations. Overflow filling machines work best with thin, free-flowing liquids that move easily through the product pathway. Products with higher viscosities may not be suitable for the overflow filling technique. High viscosity products, such as honey, toothpaste and similar products, will not be as easy to push through the return port and back to the supply tank. In products with high viscosity, using the overflow principle could lead to lengthy fill times, clogged tubes and inconsistent fills from one cycle, or even bottle, to the next. But for those bottling water, window cleaner and other free-flowing products in a clear container, the overflow filler will almost always be the ideal choice for any packaging line.
