[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Reference Figures 1-4 This embodiment is a novel plastic film punching device, including a punching frame 1, a feeding support roller 2, and a discharging support roller 3. The feeding support roller 2 is rotatably mounted on one end of the punching frame 1, and the discharging support roller 3 is rotatably mounted on the other end. One end of the discharging support roller 3 is connected to the output end of a servo motor to drive the discharging support roller 3 to rotate and wind up the punched plastic film. The winding process is intermittently paused, and the spacing between adjacent groups of holes on the plastic film is controlled by the pause time interval and the winding speed. A tension roller 4 is mounted above the feeding support roller 2. The tension roller 4 is connected to the punching frame 1 through a lifting component 6 to control the height of the tension roller 4. A punching groove 7 is opened on the top of the punching frame 1 between the feeding support roller 2 and the discharging support roller 3. A punching component 8 is mounted at the bottom of the punching groove 7 for punching. Guide rollers 5 are rotatably connected to the top surface of the punching frame 1 on both sides of the punching groove 7. The guide rollers 5 cooperate with the tension roller 4 to ensure that the plastic film can remain in a tense and open state when moving, ensuring the accuracy of punching.

[0019] In this embodiment, the punching assembly 8 includes a cutting box 81, a tube cutter connecting plate 82, a stamping tube cutter 83, a cutter head pad 84, and a fan 85. The cutting box 81 is located below the punching slot 7. Another lifting assembly 6 is located at the bottom of the cutting box 81 to control the up and down movement of the cutting box 81. During stamping, the lifting assembly 6 drives the cutting box 81 to move upward, thereby driving the stamping tube cutter 83 to stamp the plastic film. The tube cutter connecting plate 82 is detachably fixed on the top of the cutting box 81 to facilitate the replacement of the stamping tube cutter 83. Several stamping tube cutters 83 are fixed through the top of the tube cutter connecting plate 82. A cutter head pad 84 is provided on the punching frame 1 on the top surface of the punching slot 7. A fan 85 is provided on the side of the cutting box 81.

[0020] In this embodiment, the punching assembly 8 also includes a collection basket 86, a ventilation filter 87, and a sealing plate 88. The collection basket 86 with a top opening is inserted inside the cutting box 81. The ventilation filter 87 is fixed to the side of the collection basket 86 near the fan 85. The sealing plate 88 is fixed to the end of the collection basket 86 that extends to the outside of the cutting box 81. The sealing plate 88 is detachably fixed to the side wall of the cutting box 81 on both sides. Handles are symmetrically fixed to the outside of the sealing plate 88. When cleaning the collection basket 86, it is more convenient and less strenuous to pull the sealing plate 88.

[0021] In this embodiment, the width of the cutter head pad 84 is smaller than the width of the perforation groove 7, ensuring that the plastic film can pass through the perforation groove 7 from both sides of the cutter head pad 84. The outer diameter of the punching cylinder cutter 83 is smaller than the width of the perforation groove 7, allowing the punching cylinder cutter 83 to pass through the perforation groove 7 to cut the plastic film. The air inlet of the blower 85 is connected to the inside of the cutting box 81, and the air outlet of the blower 85 is located at the end away from the cutting box 81. When the blower 85 is running, it draws air from inside the collection basket 86. During cutting, a negative pressure can be generated inside the punching cylinder cutter 83 and the cutting box 81, which can suck the plastic film fragments into the collection basket 86.

[0022] In this embodiment, the lifting assembly 6 includes a support frame 61, a servo cylinder 62, and a lifting frame 63. Each set of two support frames 61 are fixed on the side wall of the punching machine frame 1. Each support frame 61 is fixedly mounted with a servo cylinder 62. The output end of each servo cylinder 62 is fixed on the lifting frame 63. The two lifting frames 63 are slidably connected to the inside of the punching machine frame 1 outside the tension roller 4 and the cutting box 81, respectively. The two ends of the tension roller 4 are rotatably connected to the inside of the lifting frame 63. The bottom surface of the cutting box 81 is fixed to the bottom surface inside the lifting frame 63.

[0023] The lifting assembly 6 also includes a slide rail 64 and a slider 65. Each lifting frame 63 has a slider 65 fixed on both sides. The slider 65 is slidably sleeved on the slide rail 64. Each slide rail 64 is fixedly installed on the support frame 61. When the servo cylinder 62 pushes the lifting frame 63 to move, the lifting frame 63 drives the slider 65 to slide on the slide rail 64.

[0024] Working principle: During stamping, first, according to the punching diameter and spacing, install the corresponding group of stamping cylinder cutters 83 on the cutting box 81. During installation, simply fix the cylinder cutter connecting plate 82 at the bottom of the group of stamping cylinder cutters 83 onto the cutting box 81. Then, one end of the plastic film passes sequentially through the gap between the tension roller 4, guide roller 5, the bottom of the cutter head pad 84, and another guide roller 5. The unloading support roller 3 rotates and winds the film. During the winding process, the height of the tension roller 4 is adjusted according to the tension of the plastic film. During adjustment, the servo cylinder 62 moves and pushes the lifting frame 63 to move, thereby driving the tension roller 4 to rise and fall, adjusting the tension of the plastic film during unwinding. After adjustment, the servo motor drives the plastic film winding to pause intermittently. During the pause, the servo cylinders 62 on both sides of the cutting box 81 move and drive the cutting box 81 to move upward. The cylinder cutter connecting plate 82 moves upward and drives the stamping cylinder cutters 83 to move upward. The plastic film on the bottom surface of the upper cutter head pad 84 is punched to complete the punching. During the punching process, the blower 85 runs and draws negative pressure into the collection basket 86 through the ventilation filter 87. Under negative pressure, the film fragments generated after punching pass through the punching cylinder 83 and fall into the collection basket 86. When the cutting box 81 moves down after punching, the blower 85 is turned off. At this time, the negative pressure inside the collection basket 86 is released, and the film fragments no longer adhere to the ventilation filter 87 and fall into the collection basket 86. The servo motor runs, driving the plastic film to move in preparation for the next punching. After all the holes are punched, the bolts are tightened to release the fixing between the sealing plate 88 and the cutting box 81. The collection basket 86 can then be pulled out, the film fragments inside the collection basket 86 can be emptied, and the cleaned collection basket 86 can be reinserted into the cutting box 81. The sealing plate 88 is then fixed to the cutting box 81.
