The upper mold module and the lower mold module can be slidably combined by a plurality of guide pillars, for example, disposed adjacent to the four corners.

The upper pad 12 is disposed on one side of the upper die holder 11 . The upper clamping plate 13 is disposed on one surface of the upper pad 12, and a template knife 131 is disposed on one surface of the upper clamping plate 13 opposite to the upper pad 12, and the periphery of the template blade 131 is configured as a zigzag structure. That is, the template knife 131 and the upper pad 12 are respectively located on both sides of the upper plate 13.

Further, the stripper plate 14 is disposed on one side of the upper plate 13 having the stencil blade 131, that is, the stripper plate 14 and the upper pad plate 12 are respectively located on both sides of the upper platen 13. The stripping plate 14 has a first hollow portion 141 corresponding to the template knife 131, and the first hollow portion 141 has a zigzag structure corresponding to the template knife 131, so that the template knife 131 can be disposed through the first hollow portion 141.

The second flap 19 is oppositely disposed with a bearing portion 191, and the bearing portion 191 has a sawtooth structure corresponding to the template cutter 131.

Therefore, when the blade material conveying device 30 conveys the blade material sheet 31 between the upper mold module and the lower mold module, and the carton material conveying device 40 conveys the paper feed tray 41 to the gap G (the paper feed plate) When the position of 41 corresponds to the template blade 131), the blade is punched out by the blade material plate 31 by the template blade 131 and fixed to the carton material sheet 41.

Incidentally, a movable combination can also be achieved between the upper clamping plate 13 and the stripping plate 14 by a plurality of guiding columns.

The upper clamping plate 13 is provided with a plurality of punching units 132 at a predetermined distance from the template knife 131, and a plurality of punching units 132 are spaced apart along the longitudinal direction of the template knife 131, and a plurality of punching units 132 are worn through the stripping unit 132. The sheet 14 is directed to the underside of the stripper plate 14. In addition, the stripper plate 14 is provided with a plurality of positioning units 142, and the plurality of positioning units 142 are located between the template knife 131 and the plurality of punching units 132, and are spaced apart along the longitudinal direction of the template knife 131.

It is worth mentioning that the length of the stencil 131 is greater than or equal to the width of the blade 31. Incidentally, the predetermined distance can be set according to the actual application, for example, corresponding to the distance that the template knife 131 can properly bear when the die cutting plate 41 is punched, or between the components to avoid interference. The distance produced. In addition, the punch of the punching unit 132 may be provided as a pentagonal tapered structure. In addition, a plurality of springs may be evenly disposed between the upper pad 12, the upper plate 13 or the stripper plate 14, so that the punching force of the punching unit 132 may be increased, and also when the stripper plate 14 is reset. Resilience.

For practical use, the blade material conveying device 30 can push the blade material sheet 31 toward the plastic wrap knife edge forming device 10 in a predetermined length (either manually or automatically), and each push stroke is performed. When the driving unit 20 drives the upper mold module to the lower mold module, the punching unit 132 forms a riveting hole on the blade material 31, and the positioning unit 142 is inserted into the formed riveting hole for performing. Positioning, and the stencil 131 also punches the blade 31. Therefore, when the squeegee blade 131 punches the blade edge plate 31, the die-cut blade is pushed against the carton material sheet 41, so that the blade edge can be fixed to the carton material sheet 41 by the rivet hole.

Due to the limitation of the structure, in the first few strokes, the blade cut by the stencil 131 does not have a rivet hole, so the blade cut by the first few strokes can only be used as scrap; In the subsequent process, since the length of the stencil blade 131 is greater than or equal to the width of the blade material plate 31, and the periphery of the stencil blade 131, for example, the front and rear sides of the blade blade 31 are provided with a zigzag structure, the blade edge is provided. The portion of the blank 31 that is die cut can be used as a blade. In addition, the arrangement of the abutment portion 191 allows the blade material 31 to be properly biased when being cut to achieve a complete blade profile.

That is to say, in addition to the waste generated in the previous itinerary, it can be called zero waste in the subsequent process. Therefore, the fresh-keeping bellows forming device and the wrap-box cutting edge forming device of the present invention can effectively reduce the generation of waste, and can cut the cutting edge once and cut the blade, and the blade can be set on the carton board.

Further, the blade material sheet 31 is made of a degradable plastic or metal material. Among them, the degradable plastic can be, for example, a plastic made of a material such as corn. When the blade material sheet 31 is made of a degradable plastic material, the plastic wrap molding apparatus 100 further includes a heat pressing device 50. Alternatively, the plastic wrap forming apparatus 100 may include the hot press device 50, and the hot stamping device 50 is not used when the blade material 31 is made of a metal material, and the degradable plastic material is used in the blade material 31. A hot press device 50 is used in the production. Wherein, the hot pressing device 50 is disposed at a distance of one side of the wrapper blade forming device 10, and the carton material conveying device 40 is a carton board having a cutting edge (the blade is made of a degradable plastic material) The 41 is conveyed to the hot press device 50 so that the blade is more firmly fixed to the carton board 41 via the hot press method.

Further, as shown in FIG. 5, the hot press device 50 includes a main body 51, a two-wheel set 52, two heating blocks 53, and two heat-resistant rubber wheels 54. The wheel set 52 and the heating block 53 are disposed on the main body 51. Of course, the main body 51 may be provided with components such as auxiliary wheels, for example, so that the carton material sheet 41 can be smoothly pressed. Each of the wheel sets 52 includes a two-wheel body 521 and a belt body 522. The two wheel bodies 521 are spaced apart from each other, and the belt body 522 is wound around the two wheel bodies 521. The two heating blocks 53 are respectively disposed in the wheel set 52 and are disposed between the two wheel bodies 521, and the two heat resistant rubber wheels 54 are disposed at one end of the adjacent two wheel sets 52. Therefore, when the carton tray conveying device 40 conveys the carton tray 41 having the blade edge to the second belt set 52, it can be driven by the belt set 52 or the carton tray conveying device 40. The two belt sets 52 are moved between each other so as to be heated by the two heating blocks 53 and heat-bonded by the heat-resistant rubber wheel 54. The distance between the two belt sets 52 corresponds to the thickness of the carton board 41, that is, the distance between the two belt sets 52 can be equal to (or slightly smaller than) the thickness of the carton board 41, or the carton board 41. Plus the thickness of the blade. At this time, the thickness of the paper feeding plate 41 plus the cutting edge is greater than the distance between the two wheel sets 52, and the compression of the spring 531 disposed by the heating block 53 can be used to achieve the matching pitch for the adhesion conduction heating. efficacy.

Incidentally, the strip body 522 is preferably made of a high temperature resistant material, and the material of the heating block 53 may be copper, and the number thereof may be one in actual use, so it is not possible to use only the above. Good implementation as a limitation.
