The modified atmosphere packaging machine is a combination of pneumatic components and mechanical devices, and automatic packaging equipment controlled by PLC and other peripheral circuits. The actuator of the device is a cylinder, which is controlled by the two-position five-way solenoid valve to advance and retreat. The working position of the cylinder is detected by the magnetic switch and the proximity switch and fed back to the PLC. The PLC sends a control command to the solenoid valve of the corresponding cylinder through the program. , thereby controlling the movement of the cylinder.
Regarding the operation instructions of the modified atmosphere packaging machine , I believe that many customers are not very familiar with it, so Shanghai Guangzhi Instrument Equipment Co., Ltd. Xiaobian hereby introduces in detail how to operate the modified atmosphere packaging machine correctly:
1. Close the left power switch;
2. Close the side thermal switch and adjust the side thermal knob to about 4-5 gears;
3. Combine the upper and lower thermal switches, adjust the lower hot knob to about 4-5 gears;
4. Close the conveyor switch and adjust the conveying knob to about 4-5 gears;
5. Adjust the heating temperature (can be set at about 130 °C first);
6. After the above operation is completed, let the machine run for about 3 minutes and then close the hot air switch (the hot air switch can also be turned off during actual operation);
7. Put the item with the shrink film installed, then shrink packaging;
8. In the actual situation, if there are too many wrinkles after shrinkage, the conveying speed can be reduced or the heating temperature can be increased. Conversely, if the shrinkage phenomenon occurs, the temperature can be lowered;
9. After the packaging is finished, first turn off the three-stage heating switch, but the conveying motor and the hot air motor continue to run for about 10 minutes, and then cut off the entire power supply.
Attention should be paid to the operation of the modified atmosphere packaging machine :
1. It is a (220v/380v voltage) single-phase/three-phase four-wire system, in which the neutral line must be connected to the machine, otherwise the machine cannot operate normally;
2. This machine has stainless steel heating tube, installed on both sides, it is very bright when heated;
3. Note that the temperature of the shrinkage chamber should be controlled below 230 °C (sixth gear). If it is operated at over temperature, it will lead to premature aging of the circuit and decrease the life of electrical components.
4. When using for more than three months, the aging of the wires in the shrinkage room should be checked and replaced as appropriate.
