Description

Technical Field

[0001] The utility model relates to the technical field of film heat shrinkage equipment, in particular to a jet-type heat shrinkage packaging machine. Background Art

[0002] After some items are packed in the box, a film will be used to seal the outside of the box through a plastic sealing device, which can effectively prevent scratches, stains and other damage, thereby extending the service life of the box;

[0003] The heat shrink film uses the change in molecular arrangement when heated to reduce the film area and tightly adhere to the product surface to achieve the packaging purpose. The existing plastic sealing equipment generally uses a heating box directly, and after the article or packaging box enters the heating box, the heating component in the heating box is used to heat and shrink the plastic film wrapped around the outside of the article or packaging box. Therefore, this heat shrinking method requires continuous heating of the heating box. Since the heating box has a certain volume, if the set temperature is insufficient, the plastic film on the outside of the article or packaging box in the heating box cannot be shrunk by sufficient heat. Therefore, the heating temperature is generally directly increased to increase the temperature in the packaging heating box. This method will increase energy consumption and cause a certain amount of heat loss. Utility Model Content

[0024] like Figure 2-Figure 3 As shown, a fixing flange 14 is fixedly installed on the top of the second connecting pipe 9, a first internal thread seat 15 is fixedly installed at the lower position outside the second connecting pipe 9, and a fixing screw 16 is connected to the internal thread of the first internal thread seat 15, a vertical lifting pipe 17 is fixedly installed on the top of the shunt pipe 10, and a plurality of second internal thread seats 18 are fixedly installed on the top of the shunt pipe 10, and the vertical lifting pipe 17 is inserted and installed in the second connecting pipe 9 and fixed by the fixing screw 16. By inserting the vertical lifting pipe 17 in the second connecting pipe 9, the installation height of the shunt pipe 10 and the air outlet pipe 13 can be adjusted;

[0025] like Figure 3-Figure 5 As shown, a plurality of third internal thread seats 19 are fixedly installed on the top of the mounting plate 11, a sealing sheet 12 is movably installed on the top of the second connecting pipe 9, a connecting screw 22 is inserted and installed on the mounting plate 11 between the two third internal thread seats 19, the mounting plate 11 is inserted and installed in the mounting groove at the bottom of the shunt pipe 10, and the top of the connecting screw 22 is threadedly connected in the corresponding second internal thread seat 18, an annular grille 21 is fixedly installed at the bottom of the sealing sheet 12, a connecting ring 20 is fixedly installed at the bottom of the annular grille 21, and the annular grille 21 is inserted and installed in the third internal thread seat 19. With the arrangement of the mounting plate 11, the installation of the sealing sheet 12 is facilitated, and the arrangement of the sealing sheet 12, the connecting ring 20 and the annular grille 21 can seal the third internal thread seat 19 that is not installed with the outlet pipe 13;

[0026] like Figure 3 , Figure 5-Figure 6 As shown, a spiral tube 23 is fixedly installed on the top of the air outlet pipe 13, and an air jet groove 24 is opened in the air outlet pipe 13.
