Problems solved by technology

The result is: the positioning accuracy is extremely high, and a slight deviation will cause "burrs". figure 2 indicated by the circle
Seriously affect the quality of the product. If the "burrs" are manually removed, the labor cost will be increased and the aesthetics will be affected; the bag-making speed is mostly 30-120 pieces / min (<10m / min), which is slow and the production efficiency is low. , with the rise of labor costs, it has seriously affected the profitability of the enterprise and put a lot of pressure on the survival and development of the enterprise; the size of the equipment is very long and takes up a lot of space

Embodiment 1

[0038] This embodiment provides a shearing device, such as Figure 4 As shown, the shearing device includes an integrated die-cutting roller 26 and a die-cutting pressure roller 33 that are all cylindrical; the integrated die-cutting roller 26 is provided with at least one cutting knife, and the shape of the cutting knife is Cut the bag shape, such as Figure 5 As shown; the cutting knife is higher than the surface of the integrated die-cutting roller 26, and the die-cutting pressure roller 26 is provided with a groove, and the part of the cutting knife higher than the surface of the integrated die-cutting roller 26 can be placed in the groove Inside, the depth of the groove is greater than or equal to 1 / 2 of the thickness of the packaging bag; the integrated die-cutting roller 26 and the die-cutting pressure roller 33 are placed in parallel, and the outer diameter of the die-cutting pressure roller 33 is greater than or equal to the outer diameter of the integrated die-cuttin...

Embodiment 2

[0047] This embodiment is different from Embodiment 1 in that the integrated die-cutting roller 26 is provided with a magnetic roller core, and the cutter is made of steel or magnetic material. Utilize the magnetism of the magnet, set the cutting knife as steel material or magnetic material, the cutting knife can be directly adsorbed and pasted on the integrated die-cutting roller 26, when replacing the cutting knife, directly attach the cutting knife on the integrated die-cutting roller 26 Just pull it out, easy to install and remove.

Embodiment 3

[0049] Such as image 3 As shown, this embodiment provides a bag making machine, including the shearing device described in Embodiment 1, and also includes a cylindrical heat-press sealing roller 19 and a heat-press pressure roller 20; the heat-press sealing roller Two annular electric heating ceramic blocks 45 are fixed on the 29, two cuboid middle electric heating ceramic blocks 18 are installed between the annular electric heating ceramic blocks 45, adjacent two intermediate electric heating ceramic blocks 18 and adjacent two annular electric heating ceramic blocks 45 heat press to form two packaging bags, such as Figure 6 Shown; The hot-press sealing roller 19 and the hot-press pressing roller 20 are placed in parallel, and the outer diameter of the hot-press pressing roller 20 is greater than or equal to the outer diameter of the hot-press sealing roller 19, and the hot-press sealing roller 19 and the hot-press pressing roller 20 Do opposite rotation.

Abstract

The invention discloses a cutting device and a bag making machine. The cutting device comprises an integrated die-cutting roller and a die-cutting pressing roller, wherein the integrated die-cutting roller and the die-cutting pressing roller are each in a cylindrical shape. The integrated die-cutting roller is provided with one or more cutters. Each cutter is in a shape the same as that of a cut packaging bag. The cutters are higher than the surface of the integrated die-cutting roller. The die-cutting pressing roller is provided with a groove, and the integrated die-cutting roller and the die-cutting pressing roller move in a face-to-face manner. The bag making machine comprises the cutting device, a hot-press sealing roller and a hot-press pressing roller. Electric heating ceramic blocksare fixed to the hot-press sealing roller. By means of the bag making machine, heat sealing, hole tearing, arc-shaped side corner cutting, arc-shaped corner central corner cutting and longitudinal and transverse slitting are integrated onto the cylindrical hot-press sealing roller and the integrated die-cutting roller to be completed; the original mode of pressing a flat object into a flat objectis changed into the mode of pressing a round object into a round object; and the bag making machine carries out actions without stopping and has the beneficial effects of being compact in structure,small in occupied area, high in bag making speed and high in splitting quality.

Description

technical field [0001] The invention relates to the technical field of bag sealing machines, and more specifically, to a shearing device and a bag making machine. Background technique [0002] With the development and progress of society, food, medicine and washing products are packaged into bags, and the amount of three-side sealed packaging bags is huge. At present, the domestic automatic three-side sealing bag-making packaging machine seals the bottom edge, seals the side, opens the tear, cuts the arc-shaped corners and central corners, and cuts are completed step by step by an independent mechanism. Actions such as tearing, cutting arc-shaped corners and central corners, and slitting are carried out by a reciprocating mechanism of flattening and flattening. figure 1 shown. The result is: the positioning accuracy is extremely high, and a slight deviation will cause "burrs". figure 2 indicated by the circle. Seriously affect the quality of the product. If the "burrs" ...
