The sealing and cutting portion 92 includes two heat sealing blocks 921 and all the knives 922 and the slits 923. The two heat sealing blocks 921 are respectively disposed on the opposite positions of the two sealing cutting wheels 91, so that the two sealing cutting wheels 91 rotate one turn. The two heat seal blocks 921 are touched once, and the cutters 922 and the slits 923 are respectively disposed at the center of the heat seal block 921 of one of the cutting wheels 91. When the heat seal block 921 corresponds, the cutter 922 The cutting block 922 and the slit 923 separate the two heat seal blocks 921 into an upper heat seal block 9211 and a lower heat seal block 9212.

As shown in FIG. 3 and FIG. 5, when the packaging is started, the feeding device 60 takes out the annularly arranged object to be packaged from an injection machine (not shown), which is a fork S in this embodiment. The forks S are placed in the through slots 631 above the turntable 63, and the ends of the forks S will be supported on the support rings 632, so that the forks S will form a slanted arrangement. This ensures that the fork S falls with the head down and falls smoothly. When a slot 631 of the dial 63 coincides with the opening 611 of the base 61, the fork S in the slot 631 is dropped into the feed passage 62 by the opening 611, and is sent to the guide through the feed passage 62. The position of the inlet section 51 of the index unit 50; the turntable 63 rotates at a fixed speed, so that the fork S can fall into the opening of the inlet section 51 and fall out from the opening of the outlet section 52, except for the feeding device 60. In addition to the aspect of the embodiment, it is also possible to carry out the feeding operation using a conventional feeding method such as manual feeding or other conveyor belt.

Referring to FIG. 6 to FIG. 8 , the film 42 on the rotating rod 41 of the film placing mechanism 40 is first wrapped around the conveying roller set 43 to make the film. The 421 can be inserted into the guiding layer 53 by the inlet section 51 of the guiding unit 50. The film 421 is restricted by the pressing block 531 and the limiting arc 532, and can be slidably disposed on the guiding layer. The surface of the layer 53 is formed, and the film 421 is originally in the form of a sheet at the inlet portion 51 of the guiding layer 53. At the position of the outlet portion 52, it is bundled to form a cylindrical shape, and the film 421 is a convex piece 4211 is formed on each side;

Referring to FIG. 6 to FIG. 8 , the protruding piece 4211 of the film 421 is clamped by the traction wheel 71 of the traction device 70 outside the guiding unit 50, so that the film 421 can be continuously scrolled, and then the film 421 can be continuously scrolled. The protruding piece 4211 is subjected to hot pressing of the hot pressing wheel 81 of the hot pressing device 80, so that the protruding piece 4211 is positioned to form the first hot pressing portion 422; then, the film having the first hot pressing portion 422 is formed. The 421 forms a cylindrical structure. When the film 421 is moved downward again, the fork S will fall into the inner space of the film 421 from the opening of the outlet section 52 of the guiding unit 50; please refer to FIGS. 9 and 10 It is shown that when the two sealing cutters 91 of the sealing and cutting device 90 rotate one turn, which is exactly the length of one package, when the sealing and cutting portions 92 on the two sealing cutting wheels 91 are opposite, the heat sealing block 921 is above the heat sealing block 9211 and the lower portion. The heat seal block 9212 can simultaneously form a second hot pressing portion 423 and a third hot pressing portion 424 on the film 421, and the second hot pressing portion 423 and the third hot pressing portion 424 are separated by the cutter. The 922 and the slit 923 form a barrier and a cut, so that the adhesive film 421 forms a heat seal on the bottom and the top of the fork S, and because the hot press device 80 of the hot press device 80 The connection position is coincident with the center of the sealing and cutting wheel 91 of the sealing and cutting device 90, so that the first hot pressing portion 422 is formed on the back surface of the whole package to form a central back sealing effect; see FIG. 11 as a package. The finished film P, the film 421 can be formed into a cylindrical three-side seal (back seal) heat-sealed packaged product P. In this embodiment, the sealing and cutting device 90 is formed with the hot pressing device 80. The first hot pressing portion 422 is vertically staggered with the hot pressing portion of the second hot pressing portion 423 or the third hot pressing portion 424, and the upper and lower ends of the first hot pressing portion 422 are at the second hot pressing. The hot pressing area 4221 is formed on the portion 423 and the third hot pressing portion 424, and the hot pressing portion 4221 of the first hot pressing portion 422 is subjected to the hot pressing of the second hot pressing portion 423 and the third hot pressing portion 424. The first hot pressing portion 422 is flattened on the adhesive film 421 and located at the center of the back surface of the integrally packaged product P. In addition, the setting of the sealing and cutting device 90 can adjust its orientation as the package seal is required.

Referring to FIG. 11, the packaged product P completed in the present embodiment is shown, and the first hot pressing portion 422 is located on the back surface of the packaged product P to be a package for back sealing (back sealing). From the front side of the packaged product P, the packaged object (fork S) can cover the first hot pressing portion 422, and the second hot pressing portion 423 and the third hot pressing portion 424 are located above and below the packaged product P. Both ends; the overall packaging effect is beautiful and simple, and the film 421 can be printed on the front side of the packaged product P with drawings and product descriptions, etc., without being affected by the hot pressing portion.

In addition, as shown in FIGS. 3 and 9, after the three-side heat-sealed finished product P is cut, it is transported by the conveyor T to the outside of the machine 30 for collection. The finished product P can also be directly under the sealing and cutting device 90 of the machine 30. Set up a collection basket to collect the action directly.

Compared with the conventional packaging machine, the three-side sealing (back sealing) packaging machine provided by the present invention has the advantage that the packaging operation can be performed only by using a single film, and the time for replacing the film can be reduced, thereby avoiding unnecessary downtime. The replacement action can improve the efficiency; furthermore, the annular design formed by the guiding device can increase the applicable range of the object to be packaged, and can be packaged as long as it can be under the exit section of the guiding unit.
