[0002] Pulp molded products (such as closable lunch boxes) are widely used in the food packaging industry due to their environmentally friendly characteristics. Taking pulp lock boxes as an example, their structure adopts a linkage design of pre-drilled holes in the bottom shell and a rotatable top cover. By rotating the top cover, it can form a snap-fit ​​seal with the holes in the bottom shell. However, the current production process has significant shortcomings: the products must first be molded, and then the transfer and punching processes must be completed manually in steps, resulting in a fragmented production process and redundant steps. This traditional model, which relies on manual labor, not only increases labor costs but also restricts overall production capacity due to low operational efficiency, making automation upgrades urgently needed.

Punching mechanism 6 is used to punch side holes on the workpiece on side hole punching positioning fixture 4.

[0022] The lock box online side-hole punching machine 100 of this utility model can be connected to the front-end equipment through the material receiving and transfer mechanism 2. After the material receiving and transfer mechanism 2 receives the workpiece at the material receiving station 11, it can transport the workpiece to the material loading station 12. Then, the material loading robot 5 transports the workpiece on the material receiving and transfer mechanism 2 to the side-hole punching contour positioning fixture 4 to position the workpiece. Then, the punching mechanism 6 punches side holes on the workpiece on the side-hole punching contour positioning fixture 4 to complete the side-hole punching process of the workpiece.

[0023] Please see Figures 1 to 3In one embodiment, the receiving and transfer mechanism 2 includes a receiving moving drive mechanism 21 and a receiving contour positioning fixture 22. The receiving moving drive mechanism 21 is disposed on the frame 1, and the receiving contour positioning fixture 22 is disposed on the receiving moving drive mechanism 21. The receiving contour positioning fixture 22 is used to receive and position the workpiece, and the receiving moving drive mechanism 21 is used to drive the receiving contour positioning fixture 22 to move back and forth between the receiving station 11 and the loading station 12. The receiving and moving drive mechanism 21 can be structured with a receiving drive motor 211, a receiving drive wheel 212, a receiving driven wheel 213, and a receiving synchronous transmission component 214. The receiving drive motor 211 is mounted on the frame 1, and its output end is connected to the receiving drive wheel 212. The receiving driven wheel 213 is rotatably connected to the frame 1. The receiving synchronous transmission component 214 is wound around the receiving drive wheel 212 and the receiving driven wheel 213. The receiving contour positioning fixture 22 is fixedly connected to the receiving synchronous transmission component 214 and slides on the frame 1. The receiving drive motor 211 drives the receiving drive wheel 212 to rotate in both directions, which in turn drives the receiving synchronous transmission component 214 to rotate via the receiving driven wheel 213, thereby driving the receiving contour positioning fixture 22 to move back and forth between the receiving station 11 and the loading station 12. However, the structure of the receiving moving drive mechanism 21 is not limited to this. For example, the receiving moving drive mechanism 21 can also adopt the existing structure of motor and lead screw mechanism, and drive the lead screw mechanism to move the receiving contour positioning fixture 22 back and forth between the receiving station 11 and the loading station 12 by the motor driving the lead screw mechanism to move back and forth.

[0024] Specifically, the receiving and contouring positioning fixture 22 includes a receiving fixture base 221 and a receiving and contouring positioning part 222. Several receiving and contouring positioning parts 222 are arranged at intervals on the receiving fixture base 221. The receiving and contouring positioning parts 222 are used to position the workpiece. The frame 1 is provided with a receiving slide rail 3. The receiving fixture base 221 is slidably mounted on the receiving slide rail 3. The receiving and moving drive mechanism 21 is connected to the receiving fixture base 221.

[0025] Please see Figure 1 and Figure 4 In one embodiment, the punching side hole contour positioning fixture 4 includes a punching side hole fixture base 41 and a punching side hole contour positioning part 42. The punching side hole fixture base 41 is disposed on the frame 1, and a plurality of punching side hole contour positioning parts 42 are disposed at intervals on the punching side hole fixture base 41. The punching side hole contour positioning parts 42 are used to position the workpiece.

[0026] Furthermore, the side hole punching and positioning part 42 is provided with a waste channel 421. The waste channel 421 has a waste collection inlet 422 on the side of the side hole punching and positioning part 42. The punching mechanism 6 is arranged at a position directly opposite to the waste collection inlet 422. When punching side holes in the workpiece, the punching mechanism 6 can push the generated waste into the waste collection inlet 422.

[0027] Furthermore, the online side-hole punching machine 100 of this utility model also includes a waste collection box 7. The waste collection box 7 is set on the frame 1 and located below the side-hole punching contour positioning fixture 4. The waste collection box 7 is used to collect waste materials falling from the waste channel 421. When punching side holes in the workpiece, the punching mechanism 6 can push the generated waste materials into the waste collection inlet 422, so that the waste materials enter the waste channel 421 and then fall into the waste collection box 7 from the waste channel 421, thereby collecting the waste materials and preventing the generated waste materials from accumulating on the frame 1, ensuring the cleanliness of the equipment. Specifically, the bottom of the side-hole punching fixture base 41 is provided with a waste guide enclosure 411 that communicates with each waste channel 421. The waste collection box 7 is located below the waste guide enclosure 411 and communicates with the waste guide enclosure 411. By setting up a waste guide barrier 411, the waste falling from the waste channel 421 is guided and limited to ensure that the waste effectively falls into the waste collection box 7 and prevents the waste from falling to other locations.

[0028] Please see Figures 1 to 3 In one embodiment, the loading robot 5 includes a loading transverse drive mechanism 51, a loading transverse frame 52, a loading lifting drive mechanism 53, and a loading suction cup module 54. The loading transverse drive mechanism 51 is mounted on the frame 1 and connected to the loading transverse frame 52. The frame 1 is provided with a guide rail 14, and the loading transverse frame 52 slides on the guide rail 14. The loading lifting drive mechanism 53 is mounted on the loading transverse frame 52, and the loading suction cup module 54 is mounted on the loading lifting drive mechanism 53. The loading transverse drive mechanism 51 drives the loading transverse frame 52 to move transversely, and the loading lifting drive mechanism 53 drives the loading suction cup module 54 to move up and down, so that the loading suction cup module 54 picks up the workpiece on the receiving and transfer mechanism 2 and transports it to the punching side hole contour positioning fixture 4. Among them, the feeding transverse drive mechanism 51 and the feeding lifting drive mechanism 53 can adopt the same principle as the receiving moving drive mechanism 21, that is, the drive is achieved by using a drive motor, driving wheel, driven wheel and synchronous transmission component. However, it is not limited to this. For example, the feeding transverse drive mechanism 51 and the feeding lifting drive mechanism 53 can also adopt the existing structure of motor and lead screw mechanism to achieve the drive.

[0029] Please see Figure 1 and Figure 4 In one embodiment, the punching mechanism 6 includes a punching movement drive module 61 and a punching cutter 62. The punching movement drive module 61 is mounted on the frame 1, and its output end is connected to the punching cutter 62. The punching movement drive module 61 drives the punching cutter 62 to move, so that the punching cutter 62 punches side holes in the workpiece on the side hole contour positioning fixture 4. The punching movement drive module 61 can adopt an existing cylinder drive structure, but is not limited thereto.

[0030] Please see Figures 1 to 3 In one embodiment, the online side-hole punching machine 100 of the present invention further includes a material unloading robot 8, which is mounted on the frame 1. The material unloading robot 8 is used to press down on the workpiece when the punching mechanism 6 punches side holes in the workpiece and to transport and unload the workpiece after the side holes are punched. Specifically, the material unloading robot 8 includes a material unloading traverse drive mechanism 81, a material unloading traverse frame 82, a material unloading lifting drive mechanism 83, and a material unloading suction cup module 84. The material unloading traverse drive mechanism 81 is mounted on the frame 1 and connected to the material unloading traverse frame 82. The material unloading traverse frame 82 is slidably mounted on the guide rail 14. The material unloading lifting drive mechanism 83 is mounted on the material unloading traverse frame 82, and the material unloading suction cup module 84 is mounted on the material unloading lifting drive mechanism 83. 3. When the punching mechanism 6 punches side holes in the workpiece, the unloading lifting drive mechanism 83 drives the unloading suction cup module 84 to press down on the workpiece on the punching side hole contour positioning fixture 4, preventing the workpiece from being squeezed and deformed during punching. After the workpiece has completed punching the side holes, the unloading lateral movement drive mechanism 81 drives the unloading lateral movement frame 82 to move laterally, and the unloading lifting drive mechanism 83 drives the unloading suction cup module 84 to lift up and down, so that the unloading suction cup module 84 can transport and unload the workpiece. In this embodiment, the unloading robot 8 can both press down on the workpiece when the punching mechanism 6 punches side holes in the workpiece, and transport and unload the workpiece after the side holes have been punched. One robot can perform both pressing and unloading functions, eliminating the need for two robots and effectively reducing costs. Among them, the unloading transverse drive mechanism 81 and the unloading lifting drive mechanism 83 can adopt the same principle as the receiving moving drive mechanism 21, that is, the drive is achieved by using a drive motor, driving wheel, driven wheel and synchronous transmission component. However, it is not limited to this. For example, the loading transverse drive mechanism 51 and the loading lifting drive mechanism 53 can also adopt the existing structure of motor and lead screw mechanism.

[0031] Please see Figure 1 In one embodiment, the online side-hole punching machine 100 of the present invention further includes a discharge conveyor belt 9, which is disposed on one side of the side-hole punching contour positioning fixture 4. The unloading robot 8 can transport the workpiece to the discharge conveyor belt 9, which is used to transport the workpiece out.

[0032] Combination Figures 1 to 4 The specific working principle of the lock box online side hole punching machine 100 of this utility model is as follows:

[0033] After the receiving and transfer mechanism 2 receives the workpiece at the receiving station 11, the receiving and transfer fixture 22 is driven by the receiving and transfer drive mechanism 21 to move to the loading station 12. Then, the loading robot 5 is driven by the loading lateral movement drive mechanism 51 to move the loading lateral movement frame 52 laterally, and the loading lifting drive mechanism 53 drives the loading suction cup module 54 to lift and lower, so that the loading suction cup module 54 picks up the workpiece on the receiving and transfer fixture 22 and transports the workpiece to the punching side hole contouring fixture 4 for positioning. Then, the punching mechanism 6 punches side holes on the workpiece on the side hole profiling positioning fixture 4. While the punching mechanism 6 is punching side holes on the workpiece, the unloading robot 8's unloading lifting drive mechanism 83 drives the unloading suction cup module 84 to descend, so that the unloading suction cup module 84 presses down on the workpiece on the side hole profiling positioning fixture 4 to prevent the workpiece from being squeezed and deformed during the punching of side holes. After the workpiece has completed the punching of side holes, the unloading robot 8's unloading lateral movement drive mechanism 81 drives the unloading lateral movement frame 82 to move laterally, and the unloading lifting drive mechanism 83 drives the unloading suction cup module 84 to rise and fall, so that the unloading suction cup module 84 transports the workpiece to the discharge conveyor belt 9 to transport the workpiece and discharge it.

[0034] In summary, the lock box online side-hole punching machine 100 of this utility model can automatically punch side holes in lock boxes, and the workpiece receiving, feeding, punching and conveying are all automated operations. It is suitable for automated production lines, which greatly improves production efficiency, is safe and reliable, and can effectively reduce labor costs.
