Electric vacuum packing machine with external pumping
Electric vacuum packing machine is generally composed of vacuum pump, control panel, sealing components, electrical components and other components. All kinds of working parameters are controlled by computer board, vacuum pump is used for vacuuming, and hot melt seal is used by sealing components. The air nozzle is extended and retracted and the sealing strip is lifted and pressed down by motor control.
Actual operation, the computer board parameters such as the preset pumping air into vacuum state, sealing, cooling, gas nozzle placed in bags in advance, and then press, vacuum pump to start pumping air into vacuum state, after reaching the preset time, vacuum pump stopped pumping air into vacuum state, A motor mouth back to gas, sealing strip, in accordance with the default parameters for hot melt sealing, after reaching the preset value, stop the seal and layering continue to press for cooling, after reaching the preset value of cooling, machine B to raise layering, do A single cycle.
Pneumatic external pumping vacuum packaging machine
The structure and working mode of the pneumatic external pumping vacuum packaging machine are roughly the same as that of the electric machine. The difference is that it does not use a motor to control the exhaust nozzle and seal strip, but through the cylinder control. Cylinder, of course, so the machine needs external compressed air. But in terms of pressure and retraction speed, it is better than the electric series.
