Workflow explanation of rolling vacuum packaging machine
Rolling vacuum packaging machine is a kind of machine with high degree of automation and high production efficiency. It consists of transmission system, vacuum chamber, inflation system, electrical system, water cooling and water washing device, conveyor belt and fuselage. The vacuum pump is installed outside the machine, and the transmission system and electrical system are inside the cabinet on both sides of the fuselage.
During operation, the packaged items can be automatically discharged by bagging on the conveyor belt. The air pumping, inflation, sealing, cooling time and sealing temperature can be pre-selected. It can be operated automatically according to the program or single cycle operation. . In order to complete the packaging work under the inclined state, the conveyor belt can be adjusted at a certain angle, and the packaged juice is not easy to overflow outside the bag under the inclined state, and is especially suitable for the vacuum of powdery, paste and liquid juice articles. package.
The rolling vacuum packaging machine has only one vacuum chamber, but the vacuum chamber can be made larger and the heat sealing strip is also longer in size, so it can be used to package large-sized items, and is also suitable for large-sized packaging operations of small bags. The vacuum packaging machine can be put into several bags at the same time to vacuum and heat seal. The sealing device is cooled by internal water, the sealing is flat and firm, the cooling is fast, and the spray water pipe is provided for easy cleaning. The heat sealing quality is usually better than the room type. Vacuum packaging machine.
The vacuum system and heat sealing principle of the rolling vacuum packaging machine are the same as the chamber vacuum packaging machine, but the opening and closing of the vacuum cover of this model does not require manual operation, and can be automatically opened and closed, the working cycle is faster, and the cycle is shorter. The working cycle is 128~303, so the production efficiency is higher.
With the widespread use of vacuum packaging machines on the market, the number of operators of vacuum packaging machines is also increasing. It is necessary for operators to understand and master the operating rules and procedures of vacuum packaging machines because The familiar use of vacuum packaging machines not only improves the efficiency of the equipment, but also makes the equipment longer.
*: Vacuum-packing the package to a predetermined vacuum: put the vacuum packaging bag with the package into the vacuum chamber, then close the vacuum cover, the vacuum pump starts working, and the vacuum chamber is pumped. The vacuum condition will be reached in the bag at the same time, the vacuum gauge pointer will rise, and the predetermined vacuum degree will be reached. The time control is realized by the time relay ISJ. After the pumping is completed, the vacuum pump automatically stops working. At the same time as the vacuum packaging machine is working, the two-position three-way solenoid valve IDT starts to work, the air bag maintains the vacuum, and the heat sealing pressure frame remains in place.
Second: heat-sealing the package: After the solenoid valve IDT is disconnected, the outside atmosphere enters the inside of the airbag through the upper air intake hole, and the airbag is inflated and expanded by the pressure difference between the inside of the vacuum chamber and the airbag, so that the heat-sealing pressure frame Jack up and press the pocket. At the same time, the transformer is heat sealed and the sealing is started. At the same time, the time relay ISJ starts to work, the work is completed in a few seconds, and the heat seal ends.
Third: vacuum chamber air intake: 2/2-way solenoid valve 2DT is opened, the atmosphere enters the vacuum chamber, the pointer of the vacuum packaging machine returns to the zero position, the heat sealing pressure frame is reset by the return spring, and the upper cover of the vacuum packaging machine is opened. 4. Cycling operation: The double chamber vacuum packaging machine moves the vacuum chamber to another vacuum chamber according to the program steps, and enters the next working cycle. The left and right chambers alternately work and reciprocate.
