The first cutter part is located below the second cutter part and is inclined downward. Therefore, when cutting, the cutter punch moves relative to the cutter die. First, the first cutter part gradually contacts and cuts the corner of the packaging bag to cut the arc corner on the packaging bag, avoiding pulling the packaging bag damaged. Then, through the straight-edge cutter that matches the forming groove, that is, the second cutter part, two adjacent packaging bags are cut and separated at one time, so as to avoid the phenomenon of wire drawing or tearing when the packaging bag is cut and ensure the cutting quality.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0021] As Figure 1 、 Figure 2 and Figure 4 shown, the present invention provides a technical solution: a combined round corner cutter, including a base 1, guide posts 11 are installed on both sides of the top end of the base 1, a fixed seat 12 is installed at the top ends of the two groups of guide posts 11, a cylinder 2 is installed at the top end of the fixed seat 12, and the output end of the cylinder 2 penetrates through the fixed seat 12 and is installed with a mounting plate 21. A cutter assembly 3 is arranged at the bottom end of the mounting plate 21, and an adjusting mechanism for adjusting the cutter assembly 3 is arranged inside the mounting plate 21. The adjusting mechanism includes a moving component 4 and a driving component 5. The cutter assembly 3 includes a first cutter 31, and the first cutter 31 is installed at the bottom end of the mounting plate 21. A number of second cutters 32 are installed on both sides of the first cutter 31 through the moving component 4. This structure drives the mounting plate 21 to move downward by starting the cylinder 2. The mounting plate 21 drives the first cutter 31 and a number of second cutters 32 to move downward until the first cutter 31 and the second cutters 32 cut open two adjacent packaging bags and cut the corners into a circular arc shape, reducing the possibility of the sharp corners of the packaging bag stabbing the user and greatly increasing the safety of the packaging bag.
[0022] It should be noted that the first cutter 31 is linear and can cut open adjacent packaging bags, and the second cutter 32 is circular arc-shaped and can cut the sharp corners of the packaging bag into rounded corners.
[0023] As an implementation manner in this embodiment, as Figure 2 and Figure 3 shown, the moving component 4 includes an installation groove 41 which is opened inside the installation plate 21. Both sides of the installation groove 41 are slidably installed with screw sleeves 42 through driving components 5. Both sides of the outer wall of each group of screw sleeves 42 are connected with connecting blocks 43. Both sides of the inner wall of each screw sleeve 42 are provided with a first chute 44. The connecting blocks 43 slide in the first chute 44. The inner wall of each group of first chutes 44 is provided with a second chute 45. A slider 46 is slidably installed in each group of second chutes 45, and the slider 46 is connected with the connecting block 43. The tops of a number of second cutting knives 32 are fixedly connected to the corresponding sliders 46. The driving component 5 includes a double-headed motor 51 which is installed inside the installation groove 41. Both ends of the double-headed motor 51 are installed with screw rods 52. The screw sleeves 42 are threadedly sleeved on the surfaces of the screw rods 52. With this structure, by starting the double-headed motor 51 to drive the two screw rods 52 to rotate simultaneously, through screw rotation, the screw rods 52 drive the screw sleeves 42 to slide in the installation groove 41. The screw sleeves 42 drive the connecting blocks 43 to slide in the first chute 44. The connecting blocks 43 drive the sliders 46 to slide in the second chute 45. In this way, the slider 46 can drive the second cutting knife 32 to move until the second cutting knife 32 is adjusted to a suitable position, so that the device can be adjusted according to the width of the packaging bag to be cut, thus being applicable to more packaging bags with different widths, greatly increasing the practicability of the device.
[0024] As an implementation manner in this embodiment, as Figure 4 shown, both sides of the bottom end of the installation plate 21 are provided with pressing components 6. Each group of pressing components 6 includes a fixed rod 61. Each group of fixed rods 61 is fixedly connected to the bottom end of the installation plate 21. The bottom end of each group of fixed rods 61 is connected with a connecting plate 62. Both sides of the bottom end of each group of connecting plates 62 are installed with connecting rods 63. The bottom end of each group of connecting rods 63 is provided with a movable groove 64. The top end inside each group of movable grooves 64 is connected with a spring 65. A movable rod 66 is slidably installed at the lower opening of each group of movable grooves 64, and the top end of the movable rod 66 is connected with the spring 65. With this structure, when the installation plate 21 drives the fixed rod 61, the fixed rod 61 drives the connecting plate 62, and the connecting plate 62 drives the connecting rod 63 to move downward, the connecting rod 63 will slowly sleeved on the movable rod 66 downward, so that the movable rod 66 moves into the movable groove 64 to compress the spring 65. Through the restoring force of the spring 65, the movable rod 66 will be pushed downward, so that the movable rod 66 can press the packaging bag, making the packaging bag not easily shift during the cutting of the packaging bag, more stable, and thus making the cutting more accurate. At the same time, by the movable rod 66 sliding in the movable groove 64, it can be adjusted according to packaging bags with different thicknesses. A rubber pad 67 is glued to the bottom end of each group of movable rods 66, so that the friction between the movable rod 66 and the packaging bag can be increased, and in this way, the packaging bag can be pressed more firmly.
[0025] Working principle: If it is necessary to cut the packaging bag, just start the double-headed motor 51 first to drive the two groups of screws 52 to rotate at the same time. Through the rotation of the threads, the screw 52 drives the nut sleeve 42 to slide in the installation groove 41. The nut sleeve 42 drives the connecting block 43 to slide in the first chute 44, and the connecting block 43 drives the slider 46 to slide in the second chute 45. In this way, the slider 46 can drive the second cutting knife 32 to move until the second cutting knife 32 is adjusted to a suitable position, so that the device can be adjusted according to the width of the packaging bag to be cut, thus being applicable to more packaging bags of different widths and greatly increasing the practicability of the device;
[0026] Then convey the materials to the base 1, and make the four corners of two adjacent packaging bags correspond to several groups of second cutting knives 32 respectively. The cutting line between two adjacent packaging bags corresponds to the first cutting knife 31. In this way, the air cylinder 2 can be started. The air cylinder 2 drives the mounting plate 21 to move downward. The mounting plate 21 will drive the pressing component 6 to move downward. At this time, the movable rod 66 will drive the rubber pad 67 to first contact the packaging bag and press the packaging bag. When the mounting plate 21 drives the fixed rod 61, the fixed rod 61 drives the connecting plate 62, and the connecting plate 62 drives the connecting rod 63 to move downward, the connecting rod 63 will slowly move downward to sleeved the movable rod 66, so that the movable rod 66 moves into the movable groove 64 to compress the spring 65. Through the restoring force of the spring 65, the movable rod 66 will be pushed downward, so that the movable rod 66 can press the packaging bag, making the packaging bag not easy to shift and more stable when cutting the packaging bag, so that the cutting is more accurate. At the same time, the mounting plate 21 will also drive the first cutting knife 31 and several groups of second cutting knives 32 to move downward until the first cutting knife 31 and the second cutting knife 32 cut two adjacent packaging bags and cut the corners into an arc shape, reducing the possibility of the sharp corners of the packaging bag stabbing the user and greatly increasing the safety of the packaging bag.
[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
