Thermal shrink packaging machine

Abstract

A thermal shrink packaging machine is revealed. A receiving base is disposed on a machine plate. Two slide rails are respectively arranged at two sides of the receiving base while a slide unit is set between the two slide rails. A power source is arranged at the receiving base and an output shaft of the power source is connected to the slide unit. The slide unit is disposed with a cutter and a vacuum nozzle. A curved guiding piece is set on the machine plate. A tear part cutter is arranged over the cutter. Thereby a tear part is formed by the tear part cutter cutting correspondingly to a tear line of thermal shrink film when the cutter is cutting the thermal shrink film. Thus users can tear apart the thermal shrink film along the tear line easily by holding the tear part.

What is claimed is: 
     
         1 . A thermal shrink packaging machine comprising: a receiving base of a film extending and cutting unit disposed on a machine plate of a machine body; each of two sides of the receiving base arranged with a slide rail, a slide unit set between the two slide rails on the receiving base; a power source arranged at the receiving base and an output shaft of the power source connected to the slide unit; a cutter disposed on the slide unit and a vacuum nozzle corresponding to the cutter and arranged on bottom of the slide unit; and a curved guiding piece corresponding to the vacuum nozzle set on the machine plate;
 wherein the film extending and cutting unit includes a tear part cutter arranged over the cutter; the tear part cutter cuts correspondingly to a tear line of thermal shrink film to form a tear part on the thermal shrink film while the power source drives the cutter to cut the thermal shrink film.
