Technical Field

[0001] The invention relates to the field of die-cutting machines, and in particular to a die-cutting and stretching integrated mechanism of a die-cutting machine. Background Art

[0002] Traditional die-cutting machines mainly include an upper template and a lower template. The upper template and the lower template die-cut passing paper, aluminum foil and other sheets through opening and closing actions to die-cut paper pieces to be formed. These paper pieces are then separated from waste paper and collected, and then sent to the forming machine again to form paper bowls, paper plates and other formed parts. These two processes require two devices to complete, which causes a waste of time in the paper transfer process and increases the labor intensity of workers. Summary of the invention

DETAILED DESCRIPTION

[0010] The present invention is specifically described below through examples, which are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention.

[0011] like Figure 1-Figure 4As shown, the present embodiment discloses a die-cutting and stretching forming integrated mechanism of a die-cutting machine, comprising an upper template 1 and a lower template 2 which are opened and closed up and down, the bottom surface of the upper template 1 is provided with a die-cutting upper die, the top surface of the lower template 2 is provided with a die-cutting lower die, the die-cutting between the upper template 1 and the lower template 2 is a flat-pressed flat die-cutting, the lower template 2 is driven by a lifting reciprocating mechanism 7, the upper template is fixedly arranged, so that the upper template and the lower template move up and down relative to each other during operation, the front side between the upper template 1 and the lower template 2 is a die-cutting forming area 3, the rear side is a stretching forming area 4, the die-cutting upper die and the die-cutting lower die are installed in the die-cutting forming area 3, and the die-cutting forming area 3 is installed with a die-cutting The upper die and the die-cutting lower die, of course, the die-cutting molding area 3 can also be installed with a laser knife die, the upper die plate 1 and the lower die plate 2 are respectively recessed upward and downward in the stretching molding area 3 to form upper and lower grooves 6, the upper groove is provided with a stretching molding upper die 52, and the lower groove is provided with a stretching molding lower die 51; when working, when the upper die plate 1 and the lower die plate 2 are closed, the die-cutting lower die and the die-cutting upper die perform a die-cutting action in the die-cutting molding area 3, and at the same time, the stretching molding upper die 52 and the stretching molding lower die 51 perform a stretching molding action on the die-cut finished product die-cut in the die-cutting area in the stretching molding area 4, and the upper end surface of the stretching molding lower die 51 is flush with the upper end surface of the lower die plate 2. Through this structure, the upper die plate 1 and the lower die plate 2 can realize the cutting and molding of multiple paper pieces with one opening and closing action, which further improves the work efficiency.

[0012] The stretching forming die 5 formed by the stretching forming upper die 52 and the stretching forming lower die 51 is one or more that are evenly distributed in sequence along the length of the upper and lower grooves.

[0013] The sheet is intermittently conveyed according to a certain stroke, and the molding position of the molding die 5 and the die-cutting position of the upper and lower templates are set to a multiple of the stroke to achieve accurate positioning of the die-cut product, improve the accuracy of stretching molding, and thus ensure the molding quality of the finished product.

[0014] Among them, the upper template 1 and the lower template 2 are installed in a casing, the upper template is fixed at the upper end of the casing, and the lower template is driven by a lifting reciprocating mechanism 7. The lifting reciprocating mechanism 7 includes a lifting plate 71 for installing the lower template, and the lifting plate 71 is guided up and down along the inner wall of the casing through a guide rail. A base 72 is arranged below the lifting plate 71, and first transmission shafts 73 are arranged on both sides of the interval between the base 72 and the lifting plate 71. A second transmission shaft 74 corresponding to the first transmission shaft 73 is arranged in the base 72. An upper connecting rod 75, a lower connecting rod 76 and a limiting connecting rod 77 are sleeved on the first transmission shaft 73. The movable end of the upper connecting rod 75 is movably connected to the lifting plate 71, and the lower end of the lower connecting rod 76 is sleeved on the second transmission shaft 74. The movable end of the limiting connecting rod 77 is movably connected to the end surface of the base 72, so that the lifting plate can be kept relative to the base. The vertical lifting activity in a flat state effectively improves the lifting stability of the lower template. It also includes a ball screw 8 and a servo motor 9. The ball screw 8 includes a nut sleeve 81 and a screw 82. The nut sleeve 81 is installed on the base 72. The screw 82 is threadedly connected to the nut sleeve 81. The screw 82 is rotatably installed on the lifting plate 71. The servo motor 9 is mounted on the lifting plate 71. The screw 82 is connected to the first belt 10 wheel. The output shaft of the servo motor 9 is connected to the second belt 10 wheel. The first belt 10 wheel and the second belt 10 wheel are connected by the belt 10 transmission. In this way, the screw can be driven to rotate forward and backward. Since the screw is threadedly connected to the nut sleeve on the base, the lifting plate can follow the screw to move up and down, thereby realizing the relative opening and closing of the stretch forming upper mold 52 and the stretch forming lower mold 51, and at the same time, it can achieve large tonnage and pressure holding effects.

[0015] By adopting the above technical scheme, after the sheet is fed between the upper template and the lower template and is die-cut in the die-cutting area, the die-cut product is die-cut and then enters between the forming dies in the forming area for pressing and forming. In this way, after die-cutting, the die-cut product is directly stretched and formed before it is separated from the waste paper, thereby improving work efficiency, thereby directly forming finished products such as paper bowls and paper plates, achieving the purpose of co-operating die-cutting and forming of the sheet and reducing the labor intensity of workers.
