Description
Technical Field
[0001] The utility model relates to the technical field of pneumatic punching, in particular to a movable pneumatic punching machine capable of punching multiple rounded corners simultaneously. Background Art
[0002] The pneumatic punch utilizes air pressure as a power source, creating a sharp, cutting edge between the punch and the die. When air pressure is applied to the punch, it rapidly impacts the material, collaborating with the die to punch the hole. The entire punching process is controlled by a pre-set punching signal from the automated equipment, ensuring accurate placement of the holes.
[0003] The pneumatic punching machines on the market that can punch multiple rounded corners of food packaging bags at the same time are only capable of punching packaging bags of a single width. To punch packaging bags of different widths, the punching equipment must be replaced and a customized mold is required, which greatly increases production costs and is inefficient.
[0004] At present, there is still a lack of a pneumatic punching machine that can move and adjust the distance according to the size of the packaging bag and can punch packaging bags of different widths. Utility Model Content

The punches 23 come in a variety of sizes and models, allowing for the production of holes of varying shapes and sizes on packaging bags, making them easy to use. Adjacent punches 23 can be adjusted in both left-right and front-to-back distances, meeting the punching requirements for bags of varying widths.
[0026] The side plate 1 is connected to two first perforated cylinder brackets 8, one first perforated cylinder bracket 8 is connected to the corresponding cylinder 9, the two fixed die frame fine-tuning plates 7 are respectively connected to two second perforated cylinder brackets 14, the two second perforated cylinder brackets 14 are respectively connected to the corresponding cylinder 9, the two perforated rounded corner die frames 6 are respectively connected to the corresponding cylinder 9, the upper first perforated cylinder bracket 8, the upper two second perforated cylinder brackets 14 and the two perforated rounded corner die frames 6 are respectively connected to the upper die 16, the lower first perforated cylinder bracket 8, the lower two second perforated cylinder brackets 14 and the two perforated rounded corner die frames 6 are respectively connected to the lower die 15, and the upper die 16 and the lower die 15 are provided with perforations 17 corresponding to the punch 23. The piston rod of the middle cylinder 9 passes through the first perforated cylinder bracket 8 on the upper side. The piston rods of the two cylinders 9 pass through the corresponding second perforated cylinder bracket 14 on the upper side. Finally, the piston rods of the last two cylinders 9 pass through the corresponding perforated rounded corner mold base 6 and are connected to the upper mold 16. The upper mold 16 and the lower mold 15 facilitate the placement and punching of packaging bags.
[0027] The side plate 1 is connected to the mounting plate 2, and the mounting plate 2 is connected to two external screws 3. The two external screws 3 pass through the corresponding mold frame fixing connecting plate 22, and the two external screws 3 are respectively threadedly connected to the corresponding convex frame 5. The use of the external screws 3 facilitates the adjustment of the punches 23 at both ends.
[0028] The mounting plate 2 is connected to two inner screws 4 by bearings, and the two inner screws 4 are respectively threadedly connected to the sliders 11, and the two sliders 11 are respectively fixedly connected to the corresponding fixed die frame fine-tuning plates 7. By using the inner screws 4, it is convenient to adjust the distance between the two middle punches 23 and the middle punch 23.

[0031] The working principle of the movable pneumatic punching machine with multiple rounded corners and simultaneous punching provided by the utility model is as follows:
[0032] When adjusting the left and right spacing of the punches 23, first rotate the outer screw 3. The outer screw 3 drives the convex frame 5, the rounded corner die frame 6 with holes, the outer guide rod 18, the outer adjustment screw 19 and the corresponding cylinder 9, the lower die 15, the upper die 16 and the punch 23 to move. The convex frame 5 drives the outer slide 10 to move along the slide rail 13 to adjust the position of the punches 23 on both sides. Then rotate the inner screw 4.

The slide 11 drives the die frame fixed connecting plate 22, the fixed die frame fine-tuning plate 7, the second perforated cylinder bracket 14, the inner guide rod 20, the inner adjustment screw 21 and the corresponding cylinder 9, the lower die 15, the upper die 16 and the punch 23 to move. The die frame fixed connecting plate 22 drives the inner slide 12 to move along the slide rail 13 to adjust the position of the two middle punches 23.
[0033] Rotate the outer adjustment screw 19, which moves the perforated corner die set 6 along the outer guide rod 18. This in turn moves the corresponding cylinder 9, lower die 15, upper die 16, and punch 23. Rotate the inner adjustment screw 21, which simultaneously moves the fixed die set fine-adjustment plate 7 along the inner guide rod 20. This in turn moves the corresponding cylinder 9, lower die 15, upper die 16, and punch 23. This allows for the front-to-back position adjustment of adjacent punches 23.
[0034] The packaging bag is placed between the upper die 16 and the lower die 15, and the cylinder 9 is controlled to work to realize the movement of the punch 23 to realize the punching of the package.
