V. Structure and PrincipleThe complete machine is composed of vacuum cover, vacuum work chamber, body,

electric section and vacuum system. The vacuum cover is equipped with a set of heating devices wherein the heating element is the nickel-chromium band installed on the heat sealing support. There is absolute insulation between the heating element and the vacuum chamber. The heat sealing support clings to the airbag. Prior to heat sealing, the air bag is in the state of low vacuum, during the course of heat sealing, the airbag connects to air gives rise to pressure difference via action of the heat-sealing electromagnetic valve YV1, which makes airbag volume become big and press down the ironing head (nickel-chromium band) for sealing and heating simultaneously, while the heating temperature and heating time can be adjusted. The vacuum work chamber is equipped with the heat pressing and sealing device to complete the packing coupled with the heat sealing support.

The power supply of this machine is three-phase four-wire system, inputting 380V, 50HZ AC power or 220V, 50HZ AC power in the form of center line. The vacuum machine motor: voltage: 220V/380V AC, 2X0.75KW power, 2800 rev./min. The heating system is of pressure regulating type, i.e. the elementary voltage of the heat sealing transformer AC 220V/380V, and secondary voltage thereof has three gears that can be adjusted via the shape on the panel. The optional voltages: 28V, 32V and 36V. The heat sealing temperature

the Packing List; whether the screw on each part of this machine is loosened or not; whether the organic glass cover of the single-chamber vacuum machine moves up and down flexibly or not; whether the vacuum cover of the double-chamber (plate) vacuum packing machine moves left and right flexibly or not.

2. All moving parts, oil holes, and oil nozzles shall be properly lubricated. According to the specifications of the vacuum pump instruction, the appropriate amount of vacuum oil is filled into the vacuum. And the vacuum oil filled via the oil inlet shall be 3/4 of oil window height, and the oil level during the pump running shall be not less than 1/4 of oil window height. The maximum oil quantity shall not exceed 3/4 of oil window height.

3. Adjustmenta. Adjustment of Vacuum Degree of Vacuum Chamber In light of the need of the packed articles, select the best suction time to obtain the

appropriate vacuum degree. The longer the suction time is, the higher the vacuum degree is.b. Adjustment of heat sealing temperature and heat sealing timeAccording to the different materials of the packing bag and the different packed articles,

optimally select the heat sealing temperature (1-3 gears adjustable) and the heat sealing time on the panel (0-9.9 sec.) to obtain the optimal sealing strength. Adjust the temperature low to high to make the desired appearance and the strength available for sealing

VIII. Operating Procedures1. Switch on: turn on the power switch, i.e. the power indicator is on. Set the air suction time,

heat sealing time, cooling time, and heat sealing temperature.2. Pack the articles into the packing bag (compound-plastic bag or compound-aluminum foil

bag), put the packing bag in any vacuum chamber, lift the batten, put the bag mouth evenly under the heat sealing support for arrangement, and then put down the batten.

3. Screw down the vacuum cover, i.e. the suction (vacuum) indicator on the panel is on. The vacuum machine starts suction to enable the machine cover to be automatically pulled. The pump down time can be adjusted appropriately according to the packing requirements.

4. When the suction reaches the set time (i.e. required vacuum degree), the suction will come to an end, and the indicator will be off and the heat sealing indicator will be on, in this case, the electromagnetic valve will act, thus the sealing procedure will begin. There is a heat sealing time button and a temperature adjusting button on the panel. Note that the time and temperature shall be adjusted according to the specifications of the packing bag.

5. When the set heat sealing time is reached, the heat sealing indicator will be off to end the heat sealing and complete the cooling procedure. In this case, the air-out electromagnetic valve will act, the air will enter the vacuum chamber, the vacuum cover will be lifted automatically, and thus the progress of the vacuum gas packing will come to an end, and the next packing cycle will get ready.

6. In case of the gas-filled vacuum packing machine, it is necessary to fill the required gas (nitrogen gas is selected in general) for heat sealing after finishing evacuating the vacuum chamber, then the residual gas (nitrogen) in the vacuum chamber must be extracted, finally, the air-out electromagnetic vale acts and the packing progress ends.
