[0028] Please see Figure 1-5 This utility model provides a technical solution:

[0029] A plastic bag punching forming machine includes a base 1, a groove 3 on the upper front end of the base 1, a rotating mechanism 2 fixedly connected to the upper right side of the groove 3, support columns 5 fixedly connected to all four sides of the upper end of the base 1, a connecting plate 7 fixedly connected to the upper end of the four support columns 5, a punching mechanism 6 fixedly connected to the upper rear end of the base 1, and a power supply box 4 fixedly connected to the front right side of the base 1.

[0030] In this embodiment, the punching mechanism 6 includes a rear support plate 61, a first cylinder 62, and a second cylinder 64. The output end of the first cylinder 62 passes through the upper front part of the rear support plate 61 and is fixedly connected to a punching tool frame 63. The output end of the second cylinder 64 passes through the upper middle part of the first cylinder 62 and is fixedly connected to an H-shaped fixing rubber plate 65. An infrared sensor 66 is provided on the front part of the upper wall of the rear support plate 61. The infrared sensor 66 is fixedly connected to the upper rear part of the base 1. The position and size of the first cylinder 62 are adapted to the position and size of the punching groove 29. The H-shaped fixing rubber plate 65 does not contact the punching tool frame 63 and has an H-shaped structure. The detection end of the infrared sensor 66 faces the placement groove 28 of the processing table 27 and the installation height of the infrared sensor 66 is higher than the upper limit position of the punching tool frame 63. The output end of the power supply box 4 is electrically connected to the input end of the drive motor 21, the first cylinder 62, the second cylinder 64, and the infrared sensor 66 through a line.

[0031] With the above scheme: the rear support plate 61 of the punching mechanism 6 is fixed to the upper rear part of the base 1; the output end of the first cylinder 62 passes through the rear support plate 61 and connects to the punching blade frame 63; the output end of the second cylinder 64 passes through the first cylinder 62 and connects to the H-shaped fixing rubber plate 65; the infrared sensor 66, model E3F-DS10C4, is fixed to the upper rear part of the base 1 with its detection end facing above the placement slot 28 of the processing table 27, and its installation height is higher than the upper limit position of the punching blade frame 63; the power supply box 4 supplies power to the drive motor 21, the first cylinder 62, the second cylinder 64, and the infrared sensor 66 through wiring; when the placement slot 28 of the processing table 27 rotates to below the punching mechanism 6, the infrared sensor 66 detects the plastic bag. The first cylinder 62 drives the punching blade frame 63 to punch along the punching groove 29. At the same time, the second cylinder 64 drives the H-shaped fixing rubber plate 65 to move down and fix the plastic bag. Since the H-shaped fixing rubber plate 65 does not contact the punching blade frame 63, interference is avoided. After punching is completed, the first cylinder 62 and the second cylinder 64 reset. This scheme achieves precise punching through the matching design of the first cylinder 62 and the punching groove 29. The structure of the H-shaped fixing rubber plate 65 ensures that the plastic bag is fixed stably. The position design of the infrared sensor 66 (model E3F-DS10C4) ensures the reliability of detection, thereby improving the punching efficiency and accuracy. Waste can fall into the collection drawer 211 for easy cleaning. The support column 5 and the connecting plate 7 ensure the stability of the overall structure.

[0032] In this embodiment, the rotating mechanism 2 includes a drive motor 21 and an intermittent turntable 25. The output end of the drive motor 21 passes through the base 1 and is fixedly connected to an intermittent semi-arc block 22. An extension plate 23 is fixedly connected to one side of the bottom of the intermittent semi-arc block 22. An eccentric shaft 24 is fixedly connected to the upper end of the extension plate 23 away from the intermittent semi-arc block 22. The outer surface of the intermittent turntable 25 has six intermittent grooves 213 and six arc grooves 212 respectively. A rotating column 26 is fixedly connected to the middle of the upper end of the intermittent turntable 25. A processing table 27 is fixedly connected to the upper end of the rotating column 26. Six placement slots 212 are opened around the upper end of the processing table 27. 8. A punched groove 29 is opened on one side of the lower groove wall of the placement groove 28. Six slots 210 are opened on the outer surface of the processing table 27. Each slot 210 is fitted with a collection drawer 211. An arc groove 212 on one side fits against the outer arc surface of the intermittent semi-arc block 22. The drive motor 21 is fixedly connected to the right side of the upper groove wall of the groove 3. The lower end of the rotating column 26 is movably connected to the middle of the lower groove wall of the groove 3 through a bearing. The middle of the outer surface of the rotating column 26 is interlaced and movably connected to the connecting plate 7. The arc groove 212 and the six intermittent grooves 213 are distributed equidistantly in a ring. The six collection drawers 211 are distributed equidistantly in a ring with the processing table 27 as the center.

[0033] Through the above scheme: During operation, the drive motor 21 drives the intermittent semi-arc block 22 to rotate, and its outer arc surface fits into the arc groove 212 of the intermittent turntable 25. Through the cooperation of the eccentric shaft 24 on the extension plate 23 and the intermittent groove 213, the intermittent turntable 25 drives the rotating column 26 and the processing table 27 to rotate intermittently. The six placement slots 28 rotate sequentially to the bottom of the punching mechanism 6, and the waste generated by punching falls into the collection drawer 211. This scheme, through the transmission of the drive motor 21 and the intermittent semi-arc block 22, combined with the structural design of the intermittent groove 213 and the arc groove 212, realizes the intermittent rotation positioning of the processing table 27, ensuring accurate switching of the punching station. The circular distribution of the six placement slots 28 improves processing efficiency. The circular equidistant arrangement of the collection drawer 211 facilitates the centralized collection of waste. The connection between the rotating column 26 and the bearing and connecting plate 7 ensures rotational stability.

[0034] It should be noted that this utility model is a plastic bag punching and forming machine. When the plastic bag punching and forming machine is working, the power supply box 4 supplies power to the drive motor 21, the first cylinder 62, the second cylinder 64 and the infrared sensor 66. The output end of the drive motor 21 drives the intermittent semi-arc block 22 to rotate. Its outer arc surface fits with the arc groove 212 of the intermittent turntable 25. Through the cooperation of the eccentric shaft 24 on the extension plate 23 and the intermittent groove 213, the intermittent turntable 25 drives the rotating column 26 and the processing table 27 to rotate intermittently. The six placement grooves 28 around the upper part of the processing table 27 rotate sequentially to the bottom of the punching mechanism 6. The punching groove 29 on one side of the lower groove wall of the placement groove 28 is adapted to the position and size of the first cylinder 62. When the plastic bag is placed in the placement groove After 28, the infrared sensor 66's detection end faces upwards from the placement slot 28, and its installation height is higher than the upper limit position of the punching frame 63. After detecting the plastic bag, the output end of the first cylinder 62 passes through the rear support plate 61 to drive the punching frame 63 downwards for punching. At the same time, the output end of the second cylinder 64 passes through the first cylinder 62 to drive the H-shaped fixing rubber plate 65 downwards to fix the plastic bag. After punching is completed, the first cylinder 62 and the second cylinder 64 reset, and the processing table 27 continues to rotate intermittently. The waste generated by punching falls into the collection drawer 211. The collection drawer 211 is snapped into the slot 210 on the outer surface of the processing table 27, and is distributed in a ring at equal intervals around the processing table 27. The support columns 5 around the upper end of the base 1 support the connecting plate 7 to ensure structural stability.
