[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.
[0025] Reference Figures 1-6 As shown: A fully automatic egg carton punching machine includes a frame 1, on which a feeding mechanism 2 and a punching mechanism 3 are mounted. A transfer mechanism 4 is provided between the feeding mechanism 2 and the punching mechanism 3. The punching mechanism 3 includes a lower mold 31 and an upper mold 32. The lower mold 31 is equipped with a punch, and the upper mold 32 has a clearance groove adapted to the punch. A motor is mounted on the top of the frame 1, and the output shaft of the motor is connected to the upper mold 32. Multiple guide holes are provided on the top of the frame 1, and guide rods are slidably connected in the guide holes. The guide rods are fixedly connected to the upper mold 32. The transfer mechanism 4 includes a mounting bracket 41, on which a mounting base 42 is slidably connected. A moving block 43 is slidably connected to the mounting base 42, and two sets of suction cup assemblies 44 are mounted on the moving block 43. When one set of suction cup assemblies 44 adsorbs an egg carton on the conveying mechanism, the other set of suction cup assemblies 44 adsorbs an egg carton on the lower mold 31.
[0026] In existing technologies, each time a punching machine completes a punching operation, a new egg carton needs to be manually placed, which is time-consuming and labor-intensive. To solve this problem, this device completes the continuous punching operation of egg cartons through the coordinated operation of the feeding mechanism 2, the transfer mechanism 4, and the punching mechanism 3. After the feeding mechanism 2 transports the egg carton to be processed to the designated position, the mounting bracket 41 of the transfer mechanism 4 drives the mounting base 42 and the moving block 43 to slide to the corresponding workstation. The two sets of suction cup components 44 on the moving block 43 operate alternately: one set of suction cup components 44 uses negative pressure to adsorb the unprocessed egg carton on the feeding mechanism 2, while the other set of suction cup components 44 adsorbs the egg carton on the surface of the punched lower mold 31. When the motor starts, the output shaft drives the upper mold 32 to press vertically downward along the guide rod under the guidance of the guide hole, so that the punch of the lower mold 31 accurately passes through the egg carton and enters the clearance groove of the upper mold 32 to complete the punching. After punching is completed, the upper mold 32 resets, and the transfer mechanism 4 simultaneously performs the exchange action—the suction cup assembly 44, which adsorbs the new egg carton, transfers the egg carton to the lower mold 31 for positioning, while another set of suction cup assemblies 44 moves the punched egg carton to the unloading area, forming a cyclical operation process. The sliding cooperation between the guide rod and the guide hole effectively ensures the vertical accuracy of the movement trajectory of the upper mold 32, while the alternating operation of the two sets of suction cup assemblies 44 realizes continuous and uninterrupted material transfer.
[0027] Reference Figures 1-5 As shown: The suction cup assembly 44 includes a support frame mounted on the movable block 43, a plurality of suction cups are mounted on the support frame, the plurality of suction cups are connected by air pipes, and a fan is mounted on the support frame and connected to the air pipes.
[0028] The suction cup assembly 44 of the fully automatic egg carton punching machine achieves spatial positioning through a sliding connection between the support frame and the moving block 43. When the blower is started, multiple suction cups distributed on the support frame form a negative pressure suction force through the air pipe, simultaneously adsorbing the surface of the egg carton. When the moving block 43 slides to the corresponding station of the feeding mechanism 2 or the lower mold 31, the blower starts to create a vacuum inside the suction cups. Through the air pipe, multiple suction cups apply force evenly to firmly grasp the egg carton. After adsorption is completed, the moving block 43 moves to the target position along with the mounting base 42 and the mounting bracket 41. After the blower stops running, the negative pressure is released, and the suction cups release the egg carton.
[0029] Reference Figure 1 and Figure 2 As shown: A storage box 5 is provided at the end of the frame 1 away from the feeding mechanism 2 and the punching mechanism 3.
[0030] After the suction cup assembly 44 of the transfer mechanism 4 adsorbs the perforated egg carton from the surface of the lower mold 31, the moving block 43 slides with the mounting base 42 to the end away from the processing area. At this time, the suction cup assembly 44 releases negative pressure under the control of the fan, and the egg carton falls smoothly into the storage box 5 under gravity or a slight pushing action. The storage box 5 avoids frequent manual intervention by centrally receiving and storing finished egg cartons. At the same time, its position layout matches the transfer path, ensuring that the egg cartons directly enter the storage stage after perforation, transfer, and release, forming a closed-loop production process.
[0031] Reference Figure 1 and Figure 2 As shown: The feeding mechanism 2 includes a guide rail 11 mounted on the frame 1, and an installation platform 12 is slidably connected to the guide rail 11. The bottom of the installation platform 12 is provided with a guide groove that is adapted to the guide rail 11.
[0032] The guide rail 11 is fixed on the frame 1, and the guide groove at the bottom of the mounting platform 12 is embedded in the guide rail 11 to form a limiting sliding structure, ensuring that the mounting platform 12 moves smoothly along the preset straight path.
[0033] Reference Figure 1 and Figure 2 As shown: The four corners of the mounting platform 12 are provided with threaded holes, and the mounting platform 12 is provided with a boss that matches the groove of the egg box. The boss is provided with a mounting hole that matches the threaded hole.
[0034] When the mounting platform 12 slides along the guide rail 11 to the feeding station, the boss is embedded in the groove through its geometric fit with the bottom groove of the egg box, forming a physical limit to ensure that the egg box does not deviate during the conveying process.
[0035] Reference Figure 3 and Figure 4 As shown: The mounting bracket 41 is provided with a guide block, and the mounting base 42 is provided with a through groove that matches the guide block.
[0036] The guide block on the mounting bracket 41 is embedded in the through groove of the mounting base 42 to form a sliding pair structure, which restricts the mounting base 42 to move horizontally only along the straight trajectory defined by the guide block.
[0037] The mounting platform 12 is driven by a servo motor.
[0038] The mounting platform 12 of the fully automatic egg carton punching machine is driven by a servo motor to achieve high-precision, programmable feeding control.
[0039] Reference Figures 3-5 As shown: The support frame has multiple through holes, the upper end of the suction cup has threads, and the suction cup is installed on the support frame by bolts.
[0040] After the threaded part at the upper end of the suction cup passes through the through hole of the support frame, it is screwed into the threaded section by a bolt and tightened to form a rigid connection, ensuring that the suction cup remains stable when subjected to vertical tension and lateral inertial force when adsorbing the egg box.
[0041] Working principle: When the equipment starts, the guide rail 11 of the feeding mechanism 2 and the mounting platform 12 form a precision conveying system. Driven by a servo motor, the mounting platform 12 moves linearly along the guide rail 11, and the guide groove at its bottom cooperates with the guide rail 11 to ensure motion stability. The bosses on the platform match the grooves at the bottom of the egg cartons through their geometric shapes, achieving precise positioning of the egg cartons and preventing deviation during conveying. After the egg cartons to be processed are conveyed to the designated workstation, the transfer mechanism 4 begins operation.
[0042] The transfer mechanism 4 consists of a sliding assembly formed by the mounting bracket 41 and the mounting base 42. A guide block on the mounting bracket 41 is embedded in a through groove in the mounting base 42, creating a linear motion constraint. The moving block 43 mounted on the mounting base 42 alternately performs adsorption tasks via two sets of suction cup assemblies 44: one set of suction cups generates negative pressure through a fan on the support frame to firmly grip the unprocessed egg cartons on the feeding platform; simultaneously, the other set of suction cups adsorbs the perforated egg cartons on the lower mold 31. This alternating operation mechanism eliminates operational interruptions, enabling continuous material flow transfer.
[0043] The punching mechanism 3 consists of a precision punching system composed of upper and lower molds 31. The lower mold 31 holds the punch, while the upper mold 32 has a corresponding clearance groove. A motor drives the upper mold 32 to move vertically along a guide rod within a guide hole at the top of the frame 1, ensuring precise alignment of the punch and the clearance groove. When the suction cup assembly 44 places a new egg carton onto the lower mold 31, the motor starts, causing the upper mold 32 to press down, and the punch penetrates the egg carton into the clearance groove to complete the punching. The sliding fit between the guide rod and the guide hole ensures the verticality of the upper mold 32's movement, guaranteeing punching accuracy.
[0044] After punching, the upper mold 32 resets under motor drive, and the transfer mechanism 4 simultaneously performs the exchange action. The suction cup assembly 44, which adsorbs new egg cartons, transfers them to the lower mold 31 for positioning, while another set of suction cup assemblies 44 moves the punched egg cartons to the storage box 5 at the end of the frame 1. The position layout of the storage box 5 is optimized and matched with the transfer path, and the egg cartons naturally fall into the box under gravity or slight vibration, achieving centralized storage of finished products. Throughout the process, the support frame of the suction cup assembly 44 is fixed to the suction cups with bolts to ensure that they can withstand vertical tension and lateral force during adsorption, while the fan achieves synchronous negative pressure control of multiple suction cups through the air pipe network.
[0045] This equipment achieves full automation from raw material supply to finished product output through precise conveying by the feeding mechanism 2, alternating adsorption by the transfer mechanism 4, vertical punching by the punching mechanism 3, and automatic material collection by the storage box 5. The timing coordination and mechanical linkage between the modules completely eliminate the need for manual intervention, significantly improving production efficiency and operational accuracy.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
