Tunnel type heat shrinking machine
Fill the water tank with an appropriate amount of water, set the heating temperature and frame immersion
time in advance and the interval between each work. When the set temperature is reached, start the machine,
and the conveyor motor drives the rotating parts of the conveyor line to transport the packaged items into
the tunnel. The lifting motor starts and the frame descends at the same time. The packages are immersed in
hot water along with the frame. The switch piece touches the down travel switch, and the frame Stop
falling. The packaging is sterilized and shrunk in hot water. When the preset immersion time is up, the
lifting motor starts again to drive the chain to reverse, and the frame rises so that the switch piece touches
the up travel switch, and the frame stops rising. The conveyor motor drives the conveyor line to convey the
packages out of the tunnel. The job is done. In the automatic control mode, the interval time is preset. After
the frame rises to the set time, the machine starts again and works in a cycle according to the last set time.
