In the utility model, when the punching mechanism 2 punches holes in the packaging bag, the packaging bag is flattened by the flattening mechanism 3 to avoid wrinkles in the packaging bag, which causes the holes to turn outward and affects the quality and appearance of the punching. The position of the punching hole of the packaging bag is limited by the limiting component 4 to prevent the inaccurate position of the hole due to the displacement of the packaging bag position;

[0025] The punching mechanism 2 includes a punching cylinder 21, the telescopic end of the punching cylinder 21 is fixedly connected to a connecting head 22, a T-shaped slide 23 is provided at one end of the connecting head 22, a T-shaped slider 24 is slidably connected to the T-shaped slide 23, a punch 25 is fixedly connected to the lower end of the T-shaped slider 24, and the T-shaped slider 24 is fixedly connected to the T-shaped slide 23 by a fixing mechanism 26. In the utility model, the fixing mechanism 26 can be used to realize the rapid replacement of the punch 25, thereby reducing the replacement time and improving the work efficiency, and facilitating the replacement of different types of punches 25.

[0026] Furthermore, the fixing mechanism 26 includes a fixing block 261, and a mounting groove 262 is provided on the connecting head 22, and the mounting groove 262 is communicated with the T-shaped slide groove 23, and the fixing block 261 is slidably connected with the mounting groove 262, and one side of the fixing block 261 is in conflict with the T-shaped slider 24, and a spring 263 is provided in the mounting groove 262, and one side of the mounting groove 262 is provided with a straight groove and passes through the connecting head 22, and one side of the fixing block 261 is provided with a shifting block 264, and the shifting block 264 is located in the straight groove. In the utility model, the fixing block 261 is pushed by the elastic force of the spring 263 to tightly fix the T-shaped slider 24. When the punch 25 needs to be replaced, the operator pulls the shifting block 264, thereby driving the fixing block 261 to move, separate it from the T-shaped slider 24, and release the punch 25, so that it can be easily taken out and replaced.

[0027] Furthermore, the flattening mechanism 3 includes a mounting plate 31, which is fixedly connected to the connecting head 22, and connecting rods 32 are arranged on both sides of the mounting plate 31. There are four connecting rods 32 and they are symmetrically placed. One end of the connecting rod 32 is pinned to the mounting plate 31, and a pressure roller 33 is rotatably connected between two symmetrical connecting rods 32. A return spring 34 is arranged between two adjacent connecting rods 32. In the utility model, when the punching cylinder 21 starts working, it will push the connecting head 22 to move downward, and the connecting head 22 will then drive the mounting plate 31 to move downward. The movement of the mounting plate 31 will be transmitted to the pressure roller 33 through the connecting rod 32, causing it to move downward as well. When the pressure roller 33 contacts the packaging bag, the two pressure rollers 33 will move outward to apply pressure to the packaging bag, thereby flattening the packaging bag and avoiding wrinkles in the packaging bag, which will cause the holes to turn outward and affect the quality and appearance of the punching.

[0028] Among them, the limiting component 4 includes a mounting seat 41, and there are at least two mounting seats 41, which are fixedly connected to the punching table 12. A screw 42 is threadedly connected to one of the mounting seats 41, and a slide rod 43 is slidably connected to the other mounting seat 41. A limiting baffle 44 is arranged at one end of the screw 42 and the slide rod 43, and the screw 42 is rotatably connected to the limiting baffle 44. The limiting baffle 44 in the utility model functions to limit the packaging bag. The limiting baffle 44 can be driven to move by rotating the screw 42, and the position of the limiting baffle 44 can be adjusted to adapt to packaging bags of different sizes or adjust the position of the packaging bag during the punching process, so as to achieve fast and accurate positioning of the packaging bag and improve the efficiency and accuracy of the punching operation.

[0029] In addition, a pressure groove is provided on one side of the limit baffle 44, and a pressure block 45 is rotatably connected to the pressure groove via a rotating shaft. A torsion spring is provided on the rotating shaft, and both ends of the torsion spring are respectively fixedly connected to one end of the pressure block and the limit baffle 44. In the utility model, when the packaging bag is placed on the limit baffle 44, the pressure block 45 will apply pressure to the packaging bag under the action of the torsion spring, ensuring that the packaging bag maintains a fixed position during the punching process to prevent movement.

[0030] In addition, an avoidance hole 13 is provided on the punching table 12, and a material receiving port 14 is provided on one side of the C-shaped bracket 11. The material receiving port 14 is connected to the avoidance hole 13, and a drawer 15 is slidably connected to the material receiving port 14. The drawer 15 in the utility model is convenient for collecting and removing waste during the punching operation. When the drawer 15 is full, it can be easily pulled out, the waste can be poured out, and then it can be slid back into the position below the material receiving port 14 to continue collecting waste.

[0031] Working method: When working, place the packaging bag on the limit baffle 44, and the pressure block 45 will apply pressure to the packaging bag under the action of the torsion spring to ensure that the packaging bag remains in a fixed position during the punching process to prevent movement. The limit baffle 44 is driven to move by rotating the screw 42. The position of the limit baffle 44 can be adjusted to accommodate packaging bags of different sizes or to adjust the position of the packaging bag during the punching process. When the punching cylinder 21 starts working, it will push the connecting head 22 to move downward, and the connecting head 22 will then drive the mounting plate 31 to move The movement of the mounting plate 31 will be transmitted to the pressure roller 33 through the connecting rod 32, causing it to move downward as well. When the pressure roller 33 contacts the packaging bag, the two pressure rollers 33 will move outward to apply pressure to the packaging bag, thereby flattening the packaging bag and avoiding wrinkles in the packaging bag, which will cause the holes to turn outward and affect the quality and appearance of the punching. When the punch 25 needs to be replaced, the operator pulls the shift block 264, thereby driving the fixed block 261 to move, separate it from the T-shaped slider 24, and release the punch 25, so that it can be easily taken out and replaced.
