Description

Technical Field

[0001] This utility model relates to the technical field of aluminum foil lunch boxes, and in particular to a fully automatic aluminum foil lunch box stacking machine. Background Technology

[0002] To facilitate the stacking of aluminum foil lunch boxes, fully automatic stacker machines are used. Currently, there is an automated palletizing machine for aluminum foil packaging lunch boxes (authorization announcement number: CN220975826U). Through a stacking structure, the produced lunch boxes are placed on a conveyor assembly via a feeding plate. The conveyor assembly then transfers the lunch boxes to a stacking plate for stacking. When a certain number of boxes are stacked, a servo motor drives a rotating rod to rotate a wheel, which in turn rotates a belt, causing the stacking plate to descend for workers to collect the lunch boxes. Simultaneously, a servo motor drives a gear to rotate. Since the gear meshes with two rack plates, its rotation causes two moving plates to move inwards, thus supporting the lunch boxes conveyed by the conveyor assembly.

[0003] While existing stacker cranes can easily stack aluminum foil food containers, their mechanical structure and control systems are optimized for specific container sizes, making it difficult to flexibly adapt to stacking requirements for containers of different sizes and shapes. When container specifications change, complex adjustments to the equipment or replacement of parts may be required to perform the corresponding stacking operation, increasing production changeover costs and time. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fully automatic aluminum foil food box stacking machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic aluminum foil food box stacking machine includes a conveyor, with screws rotatably connected to one end and the other end of the conveyor. Threaded cylinders are threadedly connected to both sets of screws. Side plates are connected to multiple sets of threaded cylinders. Platforms are connected to multiple sets of side plates. Push rods are installed on multiple sets of side plates. Support plates are installed on multiple sets of push rods.

[0007] Preferably, multiple sets of ball bearings are movably connected to the multiple sets of side plates and the platform.

[0008] Preferably, the two sets of trays are placed crosswise.

[0009] Preferably, multiple sets of sliding grooves are provided at each of the multiple sets of side plates, and the multiple sets of sliding grooves are slidably connected to the corresponding support plates.

[0010] Preferably, multiple sets of telescopic rods are installed at the conveyor, and each set of telescopic rods is connected to a corresponding side plate.

[0011] Preferably, a dual-axis motor is installed at the conveyor, with one end of the dual-axis motor and the other end connected to the corresponding screw.

[0012] Preferably, the conveyor is connected to a base at each of its four corners.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By coordinating the conveyor, screw, threaded cylinder, side plates, push rod, and pallet, the rotation of two sets of screws drives the corresponding side plates of two sets of threaded cylinders to move away from or closer to the conveyor, thus adjusting the spacing between the two sets of side plates. This not only works with the conveyor to transport and guide aluminum foil lunch boxes of various sizes for stacking, but the two pallets on which the aluminum foil lunch boxes are placed also expand adaptively due to the adjustment of the side plates to accommodate larger aluminum foil lunch boxes. Therefore, when the lunch box specifications change, there is no need for complex adjustments to the equipment or replacement of parts; the adjustment of the spacing between the two sets of side plates by rotating the screws can complete the adjustment, saving the cost and time incurred by replacing parts. For manufacturing companies that frequently change product specifications, this can effectively improve production efficiency, reduce equipment downtime, and thus reduce production costs.

[0015] 2. Through the cooperation between the side plates, the platform, and the ball bearings, when the spacing between the two sets of side plates is adjusted, the aluminum foil lunch boxes are continuously conveyed by the conveyor. With the ball bearings installed on both the side plates and the platform, the aluminum foil lunch boxes are guided and supported at one and the other ends of the bottom by the ball bearings on the platform, and the sides of the aluminum foil lunch boxes are guided by the ball bearings on the side plates. This ensures stable conveying during the stacking and conveying of aluminum foil lunch boxes of different sizes. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figures 1 to 5 An automated aluminum foil food container stacking machine includes a conveyor 1. A laser rangefinder or vision sensor can be installed on the conveyor 1 to detect the dimensions of the aluminum foil food containers. The sensor transmits the detected container dimensions to the control system, which automatically calculates and adjusts the spacing of the side plates 4 and the position of the pallet 7 based on the container dimensions, enabling the machine to automatically adapt to different container sizes. This further enhances the machine's intelligence, reduces manual intervention, and improves production efficiency and stacking accuracy. Both ends of the conveyor 1 are rotatably connected to screws 2, and both sets of screws 2 are threadedly connected to threaded cylinders 3. The screws 2 and threaded cylinders 3 can be made of wear-resistant materials such as high-strength alloy steel, effectively improving their wear resistance and extending their service life. For example, using heat-treated 40Cr alloy steel significantly improves hardness and wear resistance compared to ordinary steel, ensuring good thread fit accuracy during long-term operation and reducing adjustment errors caused by wear. Multiple sets of threaded cylinders 3 are connected to side plates 4, multiple sets of side plates 4 are connected to a platform 5, multiple sets of side plates 4 are equipped with push rods 6, and multiple sets of push rods 6 are equipped with support plates 7. By using the push rods 6 to move the support plates 7, the aluminum foil lunch boxes continuously conveyed by the conveyor 1 can be easily stacked. By rotating the screw 2, the spacing between the side plates 4 and the space formed by the multiple support plates 7 can be adjusted, making the equipment operation more intuitive and convenient. For example, during production, when it is necessary to change the lunch box specifications, on-site operators can quickly make adjustments, reducing production delays caused by equipment adjustments.

[0024] In this embodiment, multiple sets of ball bearings 8 are movably connected to multiple sets of side plates 4 and platform 5. Two sets of trays 7 are placed crosswise, so that when the spacing between the two sets of trays 7 is adjusted and expanded with the side plates 4, there is still a point of contact between them to ensure the stability of the aluminum foil lunch box. Multiple sets of sliding grooves 10 are opened on multiple sets of side plates 4, and the multiple sets of sliding grooves 10 are slidably connected to the corresponding trays 7, which can increase the stability of the lifting and moving of the trays 7. Multiple sets of telescopic rods 9 are installed at the conveyor 1, which can increase the lateral movement stability of the side plates 4. The multiple sets of telescopic rods 9 are connected to the corresponding side plates 4. A dual-axis motor 11 is installed at the conveyor 1. One end of the dual-axis motor 11 and the other end are connected to the corresponding screws 2. The model of the dual-axis motor 11 is selected according to the actual working requirements. An encoder can be installed on the dual-axis motor 11 to monitor the motor speed, direction and rotation angle in real time. Based on the signals fed back from the encoder, the control system can precisely control the operation of the motor, achieving accurate positioning of the screw 2's rotation, thereby accurately adjusting the spacing of the side plates 4. For example, when it is necessary to adjust the spacing of the side plates 4 to a specific size, the control system precisely controls the amount of motor rotation based on the preset value and the motor position information fed back from the encoder, ensuring that the adjustment error of the side plate 4 spacing is controlled within a very small range, improving the equipment's adaptability to aluminum foil lunch boxes of different sizes. Each of the four corners of the conveyor 1 is connected to a base 12.

[0025] The working principle of this embodiment is as follows: In use, the dual-axis motor 11 drives two sets of screws 2 to rotate synchronously according to the actual size of the aluminum foil lunch box. In this way, multiple sets of screws 2 can drive the corresponding threaded cylinders 3 to move the two sets of side plates 4 synchronously away from the conveyor 1 to adjust the distance between the two sets of side plates 4. At the same time, the two sets of pallets 7 can also be expanded accordingly. After the adjustment is completed, the conveyor 1 is used for transportation. When the conveyor 1 is transporting the aluminum foil lunch box, due to the adjustment of the distance between the two sets of side plates 4, one side and the other side of the aluminum foil lunch box can contact the ball bearings 8 at the two sets of side plates 4. One bottom end and the other end of the aluminum foil lunch box can contact the ball bearings 8 at the two platform bodies 5. In this way, aluminum foil lunch boxes of different sizes can be transported stably. When the aluminum foil lunch boxes move continuously to the two sets of pallets 7, the push rod 6 drives the pallets 7 to move down, which can realize the stacking work when the aluminum foil lunch boxes fall continuously to the pallets 7.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
