Stretch film
packaging machine how to achieve ideal vacuum?
Stretch film packaging machine's main working principle is through the vacuum of packaging work, in order to prolong the shelf-life of the food packaging and storage effect.
Different packaging for vacuum degree also have different requirements, some of the strict in air cargo, big capability in pump pumping air.
But there are customers reflect, original vacuum force a lot of stretch film automatic vacuum packaging machine, used for a period of time was less than the original vacuum degree, this is what causes and how to deal with?
Below I to teach you a few action:
stretch film packaging machine how to achieve ideal vacuum?
1, the possible reason was that the vacuum
packing machine pumps, long time no oil change or packaging goods containing moisture for a long time, causing a small amount of water into the oil pollution, resulting in the vacuum pump can not work normally, can not meet the requirements of the vacuum degree.
Please replace the vacuum pump oil.
(
Such as import pump need to find the special oil pump manufacturers, domestic pump shell can be used)
。
Vacuum
packing machine price is different depending on the configuration and prices.
Stretch film packaging machinery packaging machine belongs to automation equipment, work efficiency is relatively high some.

2, vacuum packaging machine sealing is not good, such as small single chamber vacuum packaging equipment and external type vacuum machine is made of sponge gasket, these parts are need to regularly check, problems will also be short of packing materials required by the vacuum.
Please replace the sponge gasket or silica gel sealing strip.

Vacuum packing machine is in use process will encounter all sorts of practical production situation of challenge, is likely to vacuum packaging equipment manufacturers pay big money to buy, but because of the production of a slight change by using limitations, this needs us in the original equipment to make some changes, on the basis of the common is to adjust the vacuum time the number of seconds.
Generally speaking, the vacuum machine in the factory when the vacuum time has a fixed value, or more than the short of this scope, it needs to adjust the vacuum packaging machine control panel, the existing two methods as follows:
stretch film packaging machine how to achieve ideal vacuum?
1, change the original computer board control system, this has the advantage of simple and convenient, you just need to let the computer manufacturer to the board sent, but there are shortcomings: one, change the computer board vacuum time is limited, if the existing on the control panel to adjust vacuum time, can only guarantee at 0.
1 -
9.
9 seconds this range;
Second, vacuum packaging machine heating will be affected, when the time is too short, vacuum in the vacuum chamber will be saved a lot of air, and the sealing air pressure difference is too small can't completely open, causing unqualified bags sealing.
In addition, the vacuum room too much oxygen can lead to vacuum machine and tropical prone to oxidation, increasing failure rate.

2, adjust the vacuum packaging machine control panel method is changed to automatic vacuum machine, the advantage is fully automatic computer plate wider adjustable range, from 0.
1 -
99.
9 seconds, can satisfy all kinds of vacuum degree requirements.
Deficiency is that if the existing machines for replacement, will increase the cost of capital, equipment and as vacuum machine for automatic control panel, vacuum packaging machine corresponding lines need to reconfigure and specifications of different computer board also decided to vacuum packaging equipment appearance is different, need to send to manufacturers for extensive changes.
above about stretch film packaging machine is how to achieve the ideal vacuum degree, if your packing machine in the same condition, eliminate the solution or not, please contact a manufacturer of vacuum packaging machine, so as not to delay the production.
