[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0016] like Figure 1-4 As shown, a food packaging bag punching and conveying device with waste recycling function includes: a mounting frame 1, a support frame 2, a telescopic cylinder 3, a punching assembly, a pad block 5, and a recycling box 7. The support frame 2 is disposed on both sides of the mounting frame 1 to support the mounting frame 1. The telescopic cylinder 3 is disposed on the top of the mounting frame 1. The drilling assembly is disposed in the inner cavity of the mounting frame 1. The telescopic cylinder 3 is used to drive the drilling assembly to move up and down in the inner cavity of the mounting frame 1. The pad 5 is disposed below the mounting frame 1 and cooperates with the drilling assembly. The recycling box 7 is disposed on the rear side of the mounting frame 1 to recycle the waste generated by the drilling assembly.

[0017] The perforation operation of food packaging bags is achieved through the coordinated work of telescopic cylinder 3, perforation assembly, and pad block 5. Telescopic cylinder 3 can drive the perforation assembly to move up and down in the inner cavity of mounting frame 1. When the perforation assembly moves down to cooperate with pad block 5, it can perforate the food packaging bag located between the two, thus meeting the perforation requirements of food packaging bags in the production process. The recycling box 7 is located at the rear of the mounting frame 1 and can effectively recycle waste generated by the punching assembly. During the punching process, waste cut from food packaging bags can be recycled through the recycling box 7, preventing waste from being scattered and polluting the production environment. It also facilitates centralized waste treatment, allowing for secondary utilization or environmentally friendly processing, thus improving resource utilization and the environmental friendliness of production.

[0018] like Figure 3 As shown, the punching assembly includes: a punching blade 4 and a connecting sleeve 8, wherein the connecting sleeve 8 is used to connect the extended end of the telescopic cylinder 3 and the punching blade 4; The lower middle part of the mounting bracket 1 is provided with an extension channel 101 that cooperates with the punching knife 4, and the upper middle part of the mounting bracket 1 is provided with a first mating cavity 104 that cooperates with the connecting sleeve 8. The lower part of the connecting sleeve 8 is provided with a second mating cavity 801 that mates with the punching knife 4, and the upper part of the connecting sleeve 8 is provided with a third mating cavity 802 that mates with the extended end of the telescopic cylinder 3.

[0019] The connecting sleeve 8 serves as a connection and transmission mechanism, stably connecting the extended end of the telescopic cylinder 3 and the punch 4 together. This connection method ensures that the driving force of the telescopic cylinder 3 can be effectively transmitted to the punch 4, preventing loosening or detachment during the punching process and guaranteeing the continuity and stability of the punching operation. Furthermore, the cooperation between the connecting sleeve 8, the extended end of the telescopic cylinder 3, and the punch 4 precisely converts the linear motion of the telescopic cylinder 3 into the up-and-down motion of the punch 4, achieving efficient force transmission and motion conversion. Specifically, the connecting sleeve 8 is fixedly connected to the extended end of the telescopic cylinder 3 using a pin.

[0020] The second mating cavity 801 at the lower part of the connecting sleeve 8 mates with the punching tool 4. This detachable connection makes replacing the punching tool 4 very convenient. When the punching tool 4 wears or is damaged due to long-term use, the operator only needs to remove the punching tool 4 from the second mating cavity 801 of the connecting sleeve 8 and replace it with a new punching tool. There is no need for large-scale disassembly and reassembly of the entire punching assembly, which greatly shortens the equipment maintenance time and improves production efficiency.

[0021] like Figure 3 As shown, the punching knife 4 has an internal receiving cavity 401, which extends to the lower end of the punching knife 4. The lower end of the punching knife 4 is provided with a cutting edge 402. The side wall of the punching knife 4 is provided with a first discharge port 404 that communicates with the receiving cavity 401. The upper end of the receiving cavity 401 is provided with a guide slope 403. The lower part of the mounting frame 1 is provided with a second discharge port 102 that cooperates with the first discharge port 404.

[0022] The receiving cavity 401 inside the punching blade 4 extends to its lower end. During the punching process, waste material punched from the food packaging bag directly enters the receiving cavity 401. This prevents waste material from accumulating around the punching area, reduces interference with subsequent punching operations, ensures the continuity and smoothness of punching, and improves production efficiency. The guide slope 403 at the upper end of the receiving cavity 401 plays an important guiding role. When the waste material inside the receiving cavity 401 accumulates to a certain level, the guide slope 403 can guide the waste material in the receiving cavity 401 towards the first discharge port 404, making it easier for the waste material to be discharged from the punching blade 4 and improving the efficiency of waste material discharge. The first discharge port 404 on the side wall of the punching knife 4 cooperates with the second discharge port 102 on the lower part of the mounting frame 1. When the punching knife 4 moves upward to a certain position, the first discharge port 404 and the second discharge port 102 connect, and the waste in the receiving cavity 401 can be discharged into the recycling box through these two discharge ports. This design allows the waste to be smoothly transferred from the punching knife 4 to the recycling box 7, realizing the effective collection and treatment of waste and maintaining the cleanliness of the production environment.

[0023] like Figure 3 As shown, a pressure block 803 is slidably connected inside the connecting sleeve 8. The lower surface of the pressure block 803 abuts against the upper end of the punching knife 4. A spring 804 is provided between the upper surface of the pressure block 803 and the connecting sleeve 8. The side wall of the second mating cavity 801 is provided with a limiting pin 805, and the side wall of the punching tool 4 is provided with a sliding groove 405 for engaging with the limiting pin 805.

[0024] The lower surface of the pressure block 803, which is slidably connected inside the connecting sleeve 8, abuts against the upper end of the punching knife 4, and a spring 804 is installed between the upper surface of the pressure block 803 and the connecting sleeve 8. When the telescopic cylinder drives the punching knife 4 downward to punch a hole, the spring 804 is compressed, providing a stable and buffering pressure for the punching knife 4. This avoids the punching knife 4 being subjected to excessive impact force instantaneously, reduces damage to the cutting edge 402 of the punching knife 4, and extends the service life of the punching knife 4. It ensures that the punching knife 4 always applies appropriate and stable pressure to the food packaging bag during the punching process, ensuring uniform punching quality and depth, and improving the product qualification rate. The elasticity of the spring 804 can be selected and adjusted according to actual needs. Food packaging bags of different materials and thicknesses may require different punching pressures. By replacing the spring 804 with a different elastic coefficient or adjusting the preload of the spring 804, different punching requirements can be met, enhancing the versatility and adaptability of the equipment.

[0025] like Figure 2-3As shown, a slot 103 is provided at the lower part of the second discharge port 102, which is used to engage the recycling box 7. The slot 103 provides a simple and reliable connection method. When installing the recycling box 7, the worker only needs to align the recycling box with the slot 103 and insert it. When the recycling box 7 is full of waste and needs to be cleaned, the recycling box can be easily removed from the slot 103. This convenient installation and disassembly method saves time and labor costs and improves production efficiency.

[0026] like Figure 1 As shown, the mounting frame 1 has connecting plates 105 on both sides, and the connecting plates 105 are fixedly connected to the support frame 2 by bolts.

[0027] like Figure 1-2 As shown, a rubber pad 6 is provided on the upper surface of the pad 5. The elasticity of the rubber pad 6 allows the food packaging bag to better fit the blade 402 of the punching knife 4 during the punching process. During punching, the rubber pad 6 is compressed to a certain extent, thereby ensuring close contact between the packaging bag and the blade, ensuring more precise and neat punching, reducing the possibility of defects such as burrs and tears at the punched edges, and improving the quality and effect of punching.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
