Packing machine for data line heat shrink film

The utility model discloses a packaging machine for a data line heat shrinkage film. The packaging machine comprises a machine body, a ventilation pipe is installed on the inner side of the top end of the machine body, a dustproof net is installed on the inner side of the top end of the ventilation pipe, a filter plate is distributed below the dustproof net, an adsorption plate is distributed below the filter plate, and a guide structure is installed on one side of the filter plate. Through combined use of an air heater, a filter plate, an adsorption plate and a first spring, air sucked into the inner side of the machine body can be effectively filtered and purified, and therefore it can be prevented that too many impurities are doped in the air, and subsequent packaging treatment on the data line is affected; when the air heater works to generate wind power, the filter plate and the adsorption plate can move longitudinally, the first spring deforms along with the longitudinal movement, and the longitudinal r
