[0025] Specifically, first, place the hot pot base material packaging bag that needs to be sealed and cut on the rectangular through hole on the specially designed workbench 1 to ensure that the packaging bag can be placed firmly and facilitate subsequent sealing and cutting operations. Next, start the motor 2, and the output end of the motor 2 is tightly connected to the driving wheel 3. When the motor 2 is started, it will drive the driving wheel 3 to start rotating. The driving wheel 3 and the driven wheel 4 are engaged by gears. Therefore, when the driving wheel 3 rotates, the driven wheel 4 will also rotate synchronously. The rotation of the driven wheel 4 further drives the connecting rod 1 5 and the connecting rod 2 7 on both sides to move synchronously to achieve precise control. One end of the connecting rod 1 5 is connected to the sliding plate 1 6. When the connecting rod 1 5 moves, it will guide the sliding plate 1 6 in the guide The guide rod 11 provides a stable moving path for the sliding plate 6 to ensure that it will not deviate from the direction during the movement. Similarly, one end of the connecting rod 2 7 is connected to the connecting rod 8 and the slider 12. When the connecting rod 2 7 moves, it will drive the connecting rod 8 and the slider 12 to slide on the guide rod 11. The design of the connecting rod 8 enables it to drive the sliding plate 2 9 to move in a special way. As the sliding plates 1 6 and 2 9 move, their relative positions change. During this relative movement, the internal heat sealing plate 10 and the cutting knife 15 will begin to contact the hot pot base packaging bag. The heat sealing plate 10 seals the packaging bag by heating, and the cutting knife 15 is responsible for cutting the packaging bag after sealing.
[0026] Reference Figure 1 and Figure 4 The outer wall of the cutting knife 15 is fixedly connected to the inside of the sliding plate 6, the inside of the slider 12 is slidably connected to the guide rod 11, the outer wall of the guide rod 11 is fixedly connected to the inside of the workbench 1, the insides of the sliding plate 6 and the sliding plate 29 are fixedly connected to the telescopic rod 13, one end of the telescopic rod 13 is fixedly connected to the outer wall of the heat sealing plate 10, the outer wall of the telescopic rod 13 is sleeved with a spring 14, one end of the spring 14 is respectively fixedly connected to the inside of the sliding plate 6 and the sliding plate 29, and the other end of the spring 14 is fixedly connected to the outer wall of the heat sealing plate 10, The outer walls of the sliding plate 16 and the sliding plate 2 9 are both fixedly connected with a fixed plate 16, the outer wall of the fixed plate 16 is slidably connected to the inside of the workbench 1, the outer wall of the workbench 1 is fixedly connected with a bracket 20, the inside of the fixed plate 16 is fixedly connected with a telescopic rod 2 17, one end of the telescopic rod 2 17 is fixedly connected with a clamping plate 19, the outer wall of the clamping plate 19 is slidably connected to the inside of the fixed plate 16, the outer wall of the telescopic rod 2 17 is sleeved with a spring 2 18, one end of the spring 2 18 is fixedly connected to the outer wall of the clamping plate 19, and the other end of the spring 2 18 is fixed to the inside of the fixed plate 16;
[0027] Specifically, the heat sealing plate 10, under the precise drive of the motor 2, will slide inside the sliding plate 1 6 and the sliding plate 2 9, which will not only cause the internal spring 14 to contract and generate the necessary force to drive the next steps, but also the cutting knife 15 will gradually slide out from the inside of the heat sealing plate 10, achieving sealing and cutting at the same time, thereby improving the overall work efficiency. Moreover, the movement of the sliding plate 1 6 and the sliding plate 2 9 is not only to drive the cutting knife 15, but also drives the splints 19 on both sides to move relative to each other. Driven by the spring 2 18, the splint 19 will tightly press the hot pot base packaging bag, ensuring that the hot pot base packaging bag will not be wrinkled during the sealing and cutting process, thereby achieving stable and accurate sealing and cutting of the hot pot base packaging bag.
[0028] Working principle: when the sealing and cutting device of the food packaging bag is needed, first place the hot pot base material packaging bag to be sealed and cut on the rectangular through hole on the workbench 1, and then start the motor 2. The output end of the motor 2 will drive the driving wheel 3 to rotate, and the rotation of the driving wheel 3 will synchronously drive the driven wheel 4 to rotate, and further drive the connecting rod 1 5 and the connecting rod 2 7 on both sides to move synchronously. One end of the connecting rod 1 5 will guide the sliding plate 1 6 to slide on the guide rod 11, and one end of the connecting rod 2 7 will drive the connecting rod 8 and the slider 12 to slide on the guide rod 11. One end of the connecting rod 8 will drive the sliding plate 2 9 to move relative to the sliding plate 1 6, thereby clamping the hot pot base material packaging bag. As the sliding plate 1 6 and As the sliding plate 29 moves, the internal heat sealing plate 10 and the cutting knife 15 will begin to seal and cut the hot pot base material packaging bag. During this process, the heat sealing plate 10 will be driven by the motor 2 to slide inside the sliding plate 16 and the sliding plate 29 respectively, so that the internal spring 14 will contract. At the same time, the cutting knife 15 will gradually slide out from the inside of the heat sealing plate 10 to achieve sealing and cutting at the same time. In addition, the movement of the sliding plate 16 and the sliding plate 29 will also drive the clamping plates 19 on both sides to move relative to each other. Under the push of the spring 2 18, the clamping plate 19 will press the hot pot base material packaging bag to ensure that no wrinkles appear during the sealing process, thereby achieving stable and accurate sealing and cutting of the hot pot base material packaging bag.
