[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 5 The integrated device for printing and forming air holes of packaging bags in this embodiment mainly includes a mounting frame 1, a winding roller 2, a parallel feeding roller 3, a feeding assembly, a punching seat 8, a hydraulic push rod 10, a punching head 11, a detection sensor 15, and a printing machine 14.

[0025] Mounting frame 1 serves as the supporting structure for the entire device. It is made of high-strength metal materials, such as stainless steel, and has good stability and load-bearing capacity. It can withstand various forces generated during the operation of the device. Its shape is a rectangular frame structure, and its size is designed according to actual production needs to ensure that each component can be installed and operated reasonably.

[0026] Multiple winding rollers 2 are rotatably connected to the mounting frame 1. The number of winding rollers 2 is set according to the actual use, and can be 4-10. They are made of metal with a smooth surface to reduce friction on the coil 6. The function of the winding rollers 2 is to guide and initially support the coil 6 so that the coil 6 can be transported along a predetermined path. The parallel feed rollers 3 are rotatably connected to the mounting frame 1 and are located above the winding rollers 2. They are also made of metal and cooperate with the winding rollers 2 to ensure that the coil 6 remains parallel during the transport process and that the coil 6 can accurately pass through the material through hole 9 on the punch seat 8.

[0027] The feeding assembly is located at the rear end of the mounting frame 1 and includes a drive motor 4, a feeding roller 5, and a locking sleeve 16. The drive motor 4 is a stepper motor with appropriate power, which is fixed to the rear side of the mounting frame 1 by bolts. It can accurately control the feeding speed and feeding amount. The feeding roller 5 is connected and fixed to the output end of the drive motor 4. It is made of metal and the surface is smoothed. The coil 6 passes through the feeding roller 5 and is locked and fixed by the locking sleeve 16. The locking sleeve 16 is threaded to the outside of the coil 6. The locking sleeve 16 is made of elastic material, such as rubber. Through its elastic deformation, it tightly fixes the coil 6 to the feeding roller 5 to prevent the coil 6 from loosening or slipping during the feeding process.

[0028] The punching seat 8 is fixed to the upper rear side of the mounting bracket 1. It is made of metal material and has high strength and hardness. The punching seat 8 has a material passage hole 9. The size of the material passage hole 9 is designed according to the width of the coil material 6 and the punching requirements to ensure that the coil material 6 can pass through smoothly. A pair of hydraulic push rods 10 are provided at the upper end of the material passage hole 9. The hydraulic push rods 10 are fixed to the punching seat 8 by bolts. A punching head 11 is fixed at the push rod. The punching head 11 is made of high hardness alloy material and its shape is designed according to the shape of the required punching, such as round or square. The punching head 11 passes through the punching seat 8 and is located in the material passage hole 9. Under the push of the hydraulic push rods 10, the coil material 6 in the material passage hole 9 can be punched. The bottom wall of the punching seat 8 has a punching groove for the punching head 11 to be inserted. The punching groove is connected to the material passage hole 9. The punching head 11 moves down and is inserted into the punching groove to complete the punching work of the coil material 6, ensuring the accuracy and quality of the punching.

[0029] Multiple equally spaced marking stickers 7 are adhered to the roll material 6. The number of marking stickers 7 is set according to the actual situation. The marking stickers 7 are made of special materials with good reflective properties or magnetism so that the detection sensor 15 can detect them accurately. The marking stickers 7 correspond to the size of the roll material 6 required for each packaging bag preparation and serve as positioning marks for punching and coding.

[0030] The detection sensor 15 is fixedly installed on the front surface of the mounting bracket 1, and is set parallel to the roll 6 on the side facing the roll 6 to ensure accurate detection of the marking sticker 7. The detection sensor 15 is selected from photoelectric sensors or magnetic sensors according to the characteristics of the marking sticker 7. When the marking sticker 7 is detected, it can transmit a signal to the controller to trigger subsequent punching and coding operations.

[0031] The inkjet printer 14 is mounted on the mounting frame 1 and is used to encode and print on the surface of the roll material 6. The inkjet printer 14 includes a pair of guide rods 12, a sliding seat 13, and an inkjet head 14. The guide rods 12 are made of metal and are fixed parallel to each other on the left side of the mounting frame 1 by bolts. The sliding seat 13 is slidably mounted between the guide rods 12 and has a groove inside that cooperates with the guide rods 12 to ensure that the sliding seat 13 can slide smoothly on the guide rods 12. The inkjet head 14, located behind the roll material 6, is fixed on the right side of the sliding seat 13. The inkjet head 14 is fixed to the sliding seat 13 by bolts and can adjust the printing position and angle as needed. The sliding seat 13 is locked to the guide rods 12 by a threaded locking screw. After the position of the inkjet head 14 is adjusted, the locking screw is tightened to fix the sliding seat 13 to the guide rods 12, preventing it from moving during the printing process and ensuring the accuracy and quality of the printing.

[0032] This device is equipped with a controller, which is a programmable logic controller (PLC) or a microcontroller. It is electrically connected to components such as the drive motor 4, hydraulic push rod 10, detection sensor 15, and inkjet printer 14. The controller can receive signals from the detection sensor 15 and control the start, stop, and speed of the drive motor 4, the extension and retraction of the hydraulic push rod 10, and the printing operation of the inkjet printer 14 according to the preset program, so as to realize the automated operation of the entire device.

[0033] When in use, place the roll 6 on the unloading roller 5.

[0034] Start the drive motor 4 and begin feeding. Under the guidance of the winding roller 2 and the parallel feeding roller 3, the coiled material 6 smoothly passes through the feeding hole 9.

[0035] When the marker sticker 7 on the roll 6 moves to the detection sensor 15, the detection sensor 15 detects the marker sticker 7 and transmits a signal to the controller.

[0036] After receiving the signal, the controller simultaneously controls the hydraulic push rod 10 and the inkjet printer 14 to work. The hydraulic push rod 10 pushes the punching head 11 to move downward and insert it into the punching slot to punch the roll material 6. At the same time, the inkjet printer head 14 encodes and prints on the surface of the roll material 6.

[0037] After punching and printing are completed, roll 6 continues to be conveyed for the processing of the next packaging bag, and so on, to achieve continuous production.

[0038] Principles and beneficial effects

[0039] Working principle
