The principle of desktop vacuum packaging is based on plastic composite film or plastic aluminum foil composite film as the packaging material.Rare metals and other vacuum packaging or vacuum inflatable packaging.Lets introduce it below!
The characteristics of vacuum packaging machine
1. For liquid and high -viscosity materials, it can be filled and packaged at high precision at high temperature.(Suitable for using external pump vacuum packaging machines)
2. Use squeezing and exhaust packaging.(Internal pumping vacuum packaging machine)
3. The material is strong and corrosive, and it fully meets the food hygiene anticorrosive requirements.
4. The host structure is firm, the human -machine interface corresponding to a variety of text, and the operation is simple to operate the Atlas air compressor accessories.
5. The optimal combination can be performed with various forms of filling systems to obtain the best packaging effect.
Precautions for buying a vacuum packaging machine
1. The vacuum pump is the core. Pay attention to the core of quality and brand vacuum pump as a vacuum packaging machine. When choosing, be cautious and cautious.Whether it is large or small vacuum packaging machine pumps, the first thing we pay attention to is its price.In addition, you must also pay attention to the ability of vacuum pumps to draw vacuum. Generally, it is expressed in cubic meters/hour, but it is not bigger, the better, as long as it matches the work speed of the whole machine.
2. The principle of controlling the control of the quality of regular manufacturers is to ensure automatic and semi -automated packaging machines. The principle of controlling electrical components is used. Only electronic components of regular manufacturers can ensure durability, reliability, and safe accessories.Otherwise, it is easy to aging and may often have problems.The electrical control devices of vacuum packaging machines, packaging machines, filling machines, and three -dimensional packaging machines produced by regular manufacturers are all cited the world -famous technology technology. The quality is guaranteed and trustworthy.
3. Lightly look at fake stainless steel. Generally, regular vacuum packaging machine manufacturers are selected. Really stainless steel, such as 304 brands, is a special steel for equipment.Some small manufacturers like to use alternatives, and the thickness of the board is relatively thin.The author recommends that the product is 3mm thick steel with a type 600, while the 4mm thick steel is more than 600.
4. Choose powerful packaging machine suppliers to verify the manufacturers technical capabilities and after -sales service capabilities.Generally, you can have a general understanding through telephone communication and patronize manufacturers websites (do not buy by manufacturers without your own website). Any product is not perfect. Only manufacturers with timely and thoughtful after -sales service will not cause trouble to users oraffect production.
Vacuum packaging operating process
1. Vacuum: Vacuum room cover, vacuum pump work, vacuum room began to pump vacuum, the packaging bag was vacuum at the same time, and the vacuum sheet pointer rose to reach the rated vacuum (controlled by time relay ISJ) to stop working.While working in a vacuum, the two -way three -way solenoid valve IDT work, the hot -sealed gas room vacuum, and the thermal pressure rack is maintained in place.
2. Hot seal: IDT is broken. The external atmosphere enters the thermal chamber through its upper airing hole, and uses the pressure difference between the vacuum room and the heat -sealing gas chamber.Move and press the mouth of the bag; at the same time, the heat -seal transformer work and start sealing; at the same time, the time relay 2SJ works, the action is done a few seconds, and the thermal seal ends.
3. Elapse: Two -bit two -way solenoid valve 2DT, the atmosphere enters the vacuum chamber, the vacuum sheet pointer returns to zero, the thermal pressure rack relies on the reset spring to reset, and the vacuum chamber is opened.
4. Circulation: Move the above vacuum chamber to another vacuum chamber, that is, enter the next work process, alternate work in the left and right rooms, and reciprocate.
