[0019] Reference Figure 1-3 As shown, this utility model provides a technical solution: a side punching device for a tableware box, including a machine tool 1. The top of the machine tool 1 is provided with four sliding grooves 11. The middle part of the machine tool 1 is provided with a transmission structure for conveying plastic lunch boxes 13. The transmission structure includes a motor 2 installed on the side wall of the machine tool 1. The two sides of the machine tool 1 are connected to transmission rollers 21 through bearing components. A conveyor belt 22 is connected between the outer surfaces of the two transmission rollers 21. The output shaft of the motor 2 is fixedly connected to the transmission roller 21 on one side of the machine tool 1. When the plastic lunch box 13 is placed on the conveyor belt 22, the motor 2 is started. Motor 2 drives the conveyor roller to rotate, which in turn drives the conveyor belt 22 to transport the plastic lunch box 13. Two sliding grooves 11 are connected to the first operating plate 3 and the second operating plate 4 respectively. The top of the machine tool 1 is equipped with a bidirectional threaded rod 5 with opposite threads that is connected to the internal threads of the first operating plate 3 and the second operating plate 4. Rotating the bidirectional threaded rod 5 moves the first operating plate 3 and the second operating plate 4 to a distance that matches the conveyor belt 22, which facilitates punching and positioning of the plastic lunch box 13. A feeding channel 8 is opened on the outer surface of the machine tool 1 near the second operating plate 4. A guide plate 41 is fixed on the side of the second operating plate 4 near the feeding channel 8. A second sliding groove 12 is opened at the bottom of the machine tool 1. A waste bin 9 is slidably connected to the inner wall of the second sliding groove 12. The waste bin 9 is located below the feeding channel 8.

[0020] Reference Figure 1 and Figure 3As shown, specifically, the top of the second operation panel 4 is equipped with a punching and waste collection device 6, which includes a motor 61. The motor 61 is fixedly mounted on the top of the second operation panel 4 via a mounting base. The output shaft of the motor 61 is fixedly connected to an output rod 611. A half gear 612 is fixedly connected to the end of the output rod 611 away from the motor 61. The half gear 612 is designed so that the rack 65 can mesh with the half gear 612 at intervals, thereby causing the rack 65 to drive the arc-shaped cutter 66 to punch holes in the side wall of each plastic lunch box 13 at intervals. When the motor 61 is started, the motor drives the output rod 611 to rotate. 11 drives the half gear 612 to rotate, and the half gear 612 meshes with the rack 65. The top of the second operation plate 4 is fixedly connected to the limit block 62. The inner wall of the limit block 62 is slidably connected to the guide rod 63. One end of the guide rod 63 is fixedly connected to the rack 65. The outer surface of the end of the guide rod 63 located between the rack 65 and the limit block 62 is fitted with a spring 64. The two ends of the spring 64 are respectively connected to the outer surfaces of the limit block 62 and the rack 65. One end of the rack 65 is fixedly connected to the arc-shaped cutter 66 through a connector. The rack 65 slides along the inner wall of the limit block 62 through the guide rod 63, driving the arc-shaped cutter 66 to move to the plastic lunch box 13 limited by the positioning rod 77, and cuts the plastic... The side wall of the lunch box 13 is perforated. A connecting plate 67 is provided on the top of the second operating plate 4. A rocker plate 68 is rotatably connected to the middle of the connecting plate 67 via a shaft. A piston rod 6101 is slidably connected inside the sealing box 69 on the top of the second operating plate 4. When the half gear 612 is not engaged with the rack 65, the elastic force of the spring 64 causes the guide rod 63 to move along the inner wall of the limiting block 62, driving the rack 65 to reset. When the guide rod 63 moves, it drives the rocker plate 68 to move. The rocker plate 68 is limited by the shaft, so that the other end of the rocker plate 68 presses against the piston rod 6101. The inside of the sealing box 69 is connected to the air outlet pipe 6102. One end of the rocker plate 68 is connected to the guide rod 63. One end of the limiting block 62 is hinged by a hinge, and the other end of the rocker 68 is hinged to the end of the piston rod 6101 away from the sealing box 69 by a hinge. The top of the second operating plate 4 is provided with a support base 6103. The support base 6103 is connected to a support rod through a connecting plug. One end of the support rod is provided with a nozzle 6104. The end of the air outlet pipe 6102 away from the sealing box 69 is connected to the nozzle 6104. The piston of the piston rod 6101 moves along the inner wall of the sealing box 69, so that the gas inside the sealing box 69 is discharged through the air outlet pipe 6102, so that the nozzle 6104 blows air towards the punching place of the arc-shaped cutter 66, so that the punched waste disc is blown away and falls into the feeding channel 8.

[0021] Reference Figure 1 and Figure 2As shown in this embodiment: a limiting structure 7 is provided on the top of the first operation plate 3. The limiting structure 7 includes a second motor 71. The first operation plate 3 is fixedly connected to the second motor 71 via a mounting base. A rotating rod 73 is rotatably connected to the top of the first operation plate 3 via a bearing. When the second motor 71 is started, it drives the rotating rod 73 to rotate, causing the rotating rod 73 to drive the bearing rod 72 to rotate. At this time, the positioning rod 77 descends into the interior of the plastic lunch box 13. The bearing rod 72 is symmetrically fixedly connected to the outer surface of the rotating rod 73. A sliding frame 74 is slidably connected to the outer surface of the bearing rod 72. The output shaft of the second motor 71 is fixedly connected to the rotating rod 73. An electric telescopic rod 75 is provided on the outer surface of the support rod 72. The output end of the electric telescopic rod 75 is fixedly connected to the sliding frame 74. A connecting rod 76 is fixedly connected to one end of the outer surface of the sliding frame 74. Two V-shaped positioning rods 77 are fixedly connected to the bottom of the connecting rod 76 by bolts. When the electric telescopic rod 75 is activated, it causes the sliding frame 74 to slide along the outer surface of the support rod 72. At this time, the sliding frame 74 moves the positioning rods 77 through the connecting rod 76, so that the positioning rods 77 abut against the plastic lunch box 13. The plastic lunch box 13 is conveyed on the conveyor belt 22. The side wall of the plastic lunch box 13 has holes opened by the arc-shaped cutter 66.

[0022] Working principle: When it is necessary to punch holes in the side wall of the plastic lunch box 13, first adjust the bolts according to the size of the plastic lunch box 13 so that the support between the two positioning rods 77 is exactly against the inner wall of the plastic lunch box 13. At the same time, rotate the double threaded rod 5 so that the first operating plate 3 and the second operating plate 4 move to a distance that matches the conveyor belt 22, which facilitates punching and limiting the plastic lunch box 13. Place the plastic lunch box 13 on the conveyor belt 22, and then start the motor 2.Motor 2 drives the conveyor roller to rotate, which in turn drives the conveyor belt 22 to transport the plastic lunch box 13. When the plastic lunch box 13 is near the limiting structure 7, motor 2 71 is started. Motor 2 71 drives the rotating rod 73 to rotate, which in turn drives the bearing rod 72 to rotate. At this time, the positioning rod 77 descends into the plastic lunch box 13. Then, the electric telescopic rod 75 is started, which drives the sliding frame 74 to slide along the outer surface of the bearing rod 72. The sliding frame 74 drives the positioning rod 77 to move through the connecting rod 76, so that the positioning rod 77 abuts against the plastic lunch box 13. Motor 1 61 is started, which drives the output rod 611 to rotate, and the output rod 611 rotates. The lever 611 drives the half gear 612 to rotate, and the half gear 612 meshes with the rack 65. The design of the half gear 612 allows the rack 65 to mesh with the half gear 612 intermittently, causing the rack 65 to drive the arc-shaped cutter 66 to punch holes in the side wall of each plastic lunch box 13 at intervals. The rack 65 slides along the inner wall of the limiting block 62 via the guide rod 63, driving the arc-shaped cutter 66 to move to the plastic lunch box 13 limited by the positioning rod 77 and punch holes in the side wall of the plastic lunch box 13. At this time, the spring 64 is stretched. When the punching is finished and the half gear 612 is no longer meshing with the rack 65, the elastic force of the spring 64 causes the guide rod 63 to move along the inner wall of the limiting block 62. As the limit block 62 moves along the inner wall, it causes the rack 65 to reset. When the guide rod 63 moves, it causes the rocker arm 68 to move. The rocker arm 68 is limited by the shaft, causing its other end to press against the piston rod 6101. This causes the piston of the piston rod 6101 to move along the inner wall of the sealing box 69, allowing the gas inside the sealing box 69 to be discharged through the vent pipe 6102. This causes the nozzle 6104 to blow air towards the punching area of ​​the arc-shaped cutter 66, blowing away the punched waste discs. These discs fall into the discharge channel 8 and are collected in the waste bin 9. Alternatively, they may be blown onto the guide plate 41, where they are blocked and fall down the discharge channel to be collected in the waste bin 9. At this point, the process is initiated. The electric telescopic rod 75 drives the sliding frame 74 to move back, so that the positioning rod 77 is no longer in contact with the inner wall of the plastic lunch box 13. At this time, the motor 71 starts, causing the positioning rod 77 to disengage from the inside of the plastic lunch box 13. The plastic lunch box 13 is then conveyed away by the conveyor belt 22. At this time, the second plastic lunch box 13 to be punched moves to the vicinity of the limiting structure 7, and the above operation is repeated for punching. By setting up a punching collection device, the efficiency of punching is increased through mechanized punching. At the same time, by designing an auxiliary waste collection structure based on the movement trajectory of the arc-shaped cutter 66, the waste collection is automated, which improves production capacity and reduces the labor intensity of workers in the later cleaning, making the device practical.
