[0003] The existing patent for a punching device (publication number: CN214983623U) describes a punching device for processing food packaging bags. It solves the problems of low efficiency and high labor intensity due to the inability to punch continuously and automatically, which is not conducive to saving processing costs and improving production efficiency. However, the position of the punching head of this punching device cannot be adjusted. When there is a deviation after the position of the packaging bag is fixed, the packaging bag can only be unfixed, and then the position can be adjusted and fixed again, which is very troublesome. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a punching device for processing packaging bags, which effectively solves the problem that the position of the punching head of the punching device cannot be adjusted. When there is a deviation after the position of the packaging bag is fixed, the packaging bag can only be unfixed, and then the position can be adjusted and fixed again, which is very troublesome.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a punching device for processing packaging bags, including a workbench, with support legs fixedly installed at the four corners of the bottom of the workbench, a support frame fixedly installed on the upper part of the workbench, a drill groove opened on one side of the upper surface of the workbench, insertion holes opened at both ends of the top of the workbench, an electric push rod fixedly installed on the inner top of the workbench, a support arm fixedly installed on the transmission end of the electric push rod, insertion rods fixedly installed at both ends of the upper part of the support arm, two insertion rods inserted into the two insertion holes, a connecting strip fixedly installed on the top of the two insertion rods, and a clamping strip fixedly installed at one end of the lower part of the two connecting strips;

[0006] An opening is provided in the middle of the support frame, and a movable platform is slidably mounted in the middle of the opening via a sliding component. A cylinder is fixedly mounted on the top of the movable platform, and the transmission end of the cylinder moves downward through the movable platform and is fixedly mounted with an installation head. A drilling head is fixedly mounted at the bottom of the installation head. A servo motor is fixedly mounted on one side of the support frame via a connecting bracket. The output end of the servo motor is equipped with a transmission component, which is connected to the movable platform. When the servo motor is running, it outputs power to the movable platform through the transmission component, causing the movable platform to drive the drilling head to adjust its position.

[0007] Preferably, the sliding member includes two sliders, which are fixedly installed on the front and rear sides of the moving platform. The inner walls on both sides of the opening are provided with grooves, and the two sliders are slidably installed inside the two grooves.

[0008] Preferably, slide rods are fixedly installed on both sides of the top of the mounting head, and slide sleeves are fitted on the surface of both slide rods. The two slide sleeves are fixedly installed on the left and right sides of the moving platform.

[0009] Preferably, the transmission assembly includes a shaft, which is fixedly installed at the output end of the servo motor. A bearing seat is rotatably installed on the surface of the shaft, and the lower part of the bearing seat is fixedly connected to the top of the support frame. A transmission bar is fixedly installed at one end of the shaft, and a pin is rotatably installed at the upper end of one side of the transmission bar. A hollow strip is sleeved on the surface of the pin, and the hollow strip is fixedly connected to one side of the top of the moving platform.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator places the packaging bag on the top of the workbench and aligns the position to be drilled with the drill groove. Then, the electric push rod is activated to drive the support arm to move down. The support arm drives the two insert rods to move down along the inside of the two insert holes. When the two insert rods move down, the two connecting strips drive the two clamping strips to move down and clamp the packaging bag to fix it.

[0011] When the fixed position of the packaging bag deviates, the operator's servo motor drives the shaft to rotate inside the bearing seat. The shaft rotation drives the pin to rotate via the transmission bar, and the pin rotation drives the moving table to move via the hollow bar. The moving table moves the two sliders within the two sliding grooves, increasing the stability of the moving table. The moving table can also move the punching head to adjust the punching position. Next, the operator activates the cylinder to move the mounting head and punching head downwards. The downward movement of the mounting head causes the two sliding rods to slide within the two sliding sleeves, increasing the stability of the punching head. The punching head punches holes in the packaging bag as it moves downwards. This allows for convenient adjustment of the punching head position. When the fixed position of the packaging bag deviates, the punching head position can be directly adjusted, making adjustment very convenient. Attached Figure Description

The surface of the two sliding rods 25 is covered with sliding sleeves 26, and the two sliding sleeves 26 are fixedly installed on the left and right sides of the moving platform 12.

[0026] When the moving stage 12 moves, it causes the two sliders 22 to slide inside the two sliding grooves 23, which increases the stability of the moving stage 12 when it moves; when the mounting head 24 moves down, it causes the two sliding rods 25 to slide inside the two sliding sleeves 26, which increases the stability of the drilling head 11 when it moves.

[0027] The transmission assembly includes a shaft 17, which is fixedly installed at the output end of the servo motor 16. A bearing seat 18 is rotatably mounted on the surface of the shaft 17. The lower part of the bearing seat 18 is fixedly connected to the top of the support frame 3. A transmission bar 19 is fixedly installed at one end of the shaft 17. A pin 20 is rotatably installed at the upper end of one side of the transmission bar 19. A hollow strip 21 is sleeved on the surface of the pin 20. The hollow strip 21 is fixedly connected to one side of the top of the moving table 12.

[0028] The operator servo motor 16 drives the shaft 17 to rotate inside the bearing 18. When the shaft 17 rotates, it drives the pin 20 to rotate through the transmission bar 19. When the pin 20 rotates, it drives the moving table 12 to move through the hollow bar 21. When the moving table 12 moves, it can drive the punching head 11 to move and adjust the punching position.
