Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, specifically to an automatic metal honeycomb core forming conveyor. Background Technology

[0002] In high-speed automated production lines for honeycomb aluminum cores, aluminum coils are continuously slit into several narrow thin sheets by a slitting device. These sheets must then be immediately and precisely transferred to the feeding station of the honeycomb forming machine so that they can be simultaneously coated with adhesive, laminated, and hot-pressed with the next layer of aluminum foil. However, traditional methods generally involve manual material handling or simple conveyor belt transfer: the slit sheets are first fed longitudinally by a roller conveyor, and then lifted and transported laterally by the operator to the forming machine's material rack. This not only results in high labor intensity and limited cycle time, but also makes the thin sheets prone to surface scratches and edge warping due to repeated friction, bending, or positioning deviations, directly affecting the bonding strength and geometric accuracy of the honeycomb core. At the same time, manual intervention restricts the production line's cycle time to human labor, making it impossible to match the subsequent lamination actions that can easily reach dozens of times per minute, thus becoming a bottleneck in the efficiency of the entire production line. On the other hand, while existing general-purpose conveyors can achieve longitudinal conveying, they lack the composite function of "lifting-lateral translation-precise positioning" within the conveying plane. They cannot automatically convert longitudinal material intake to lateral feeding, and it is also difficult to synchronously limit the movement of multiple thin plates during the transfer process. This often results in misalignment and scattering of the plates, or even the plates being rolled into the subsequent rolling zone, causing equipment downtime. With the surge in demand for lightweight honeycomb structural components from aerospace, rail transportation, and new energy vehicles, aluminum honeycomb manufacturing is developing towards continuous, unmanned roll-to-roll production. The market urgently needs a dedicated transition conveying mechanism that integrates automatic material receiving, lifting and shifting, lateral stepping and pushing, and precise positioning between the aluminum coil slitting device and the honeycomb forming equipment. This mechanism would completely eliminate manual transfer links, improve the surface quality and geometric consistency of the plates, and achieve high-speed, stable, and unattended automated forming of the honeycomb core. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model relates to an automatic metal honeycomb core forming conveyor. This structure is simple and reliable, effectively solving the aforementioned technical problems and is suitable for widespread use. To achieve the above objectives, this utility model is implemented through the following technical solution: An automatic metal honeycomb core forming conveyor includes a roller conveyor line for longitudinally conveying sheet metal from an aluminum coil slitting device. The roller conveyor line has a frame with several cylinders evenly spaced longitudinally. A support plate is located inside the frame. A lifting cylinder is located at the bottom of the support plate, with its piston rod passing upwards through the support plate and connecting to a lifting plate.

The support plates are arranged laterally, with the support plates and cylinders interleaved. A transverse pushing mechanism is also provided on the lifting plate. The transverse pushing mechanism includes a movable plate that can reciprocate along a transverse straight line. Several push rods are provided on the movable plate, with the top of each push rod bent into an L-shape and located in the gap between the cylinder and the support plate.

The linear cylinder is arranged laterally on the lifting plate, and two guide rails are symmetrically arranged on both sides of the linear cylinder.

[0010] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0011] In the description of this utility model, it should be understood that the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0012] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0013] To solve the above technical problems, such as Figure 1-3As shown, this utility model designs an automatic metal honeycomb core forming conveyor, including a roller conveyor line 1. The roller conveyor line 1 is used to transport the sheet material from the aluminum coil slitting device along the longitudinal direction. The frame of the roller conveyor line 1 is provided with several cylinders 2 evenly spaced along the longitudinal direction. A support plate 3 is also provided on the inner side of the frame. A lifting cylinder is provided at the bottom of the support plate 3. The piston rod of the lifting cylinder passes upward through the support plate 3 and connects to a lifting plate 4. Horizontal plates 5 are symmetrically arranged on both sides of the lifting plate 4. One end of the two horizontal plates 5 is connected to a longitudinal plate 6. Several T-shaped positioning seats 7 are evenly spaced along the longitudinal direction on the longitudinal plate 6. A support plate 8 is provided on the top of each T-shaped positioning seat 7. The support plates 8 are arranged laterally, and several support plates 8 are staggered with several cylinders 2. The lifting plate 4 is also provided with a transverse pushing mechanism. The transverse pushing mechanism includes a movable plate 9 that can reciprocate along a transverse straight line. Several push rods 10 are provided on the movable plate 9. The top of each push rod 10 is bent into an L-shape. The push rod 10 is located in the gap between the cylinder 2 and the pallet 8. The movable plate 9 is driven by the lateral pushing mechanism to laterally push the plate lifted by the pallet 8 to the loading station of the honeycomb forming equipment. This solution integrates the original manual turning and lifting action into the frame through the three-linkage of "longitudinal feeding of the roller - lifting of the staggered pallet 8 - lateral movement of the L-shaped push rod 10". The staggered arrangement of the cylinder 2 and the pallet 8 allows the plate to be directly lifted on the original conveying surface, eliminating the need for an additional transition platform. The lifting cylinder can be activated in one operation. All strips are lifted off the roller simultaneously to avoid edge collisions caused by lifting them one by one. The push rod 10 is hidden in the gap between the cylinder 2 and the support plate 8. After being lifted, it is immediately pushed out laterally. The side of the plate is evenly stressed and will not slip or warp. The positioning accuracy is guaranteed by the mechanical stroke. The repeatability error is less than that of manual alignment. The entire process is completed within the original line width without increasing the footprint or requiring modification of the equipment before and after. The simple structure solves the three links of longitudinal material receiving, transverse transfer and precise material feeding in one go. The cycle time is synchronized with the forming machine, and the manual plate handling position is directly eliminated.

[0014] In this embodiment, it is further preferred that the lateral pushing mechanism includes a linear cylinder 11, a guide rail 12, a slider 13, and a pusher 14. The linear cylinder 11 is arranged laterally on the lifting plate 4. Two guide rails 12 are symmetrically arranged on both sides of the linear cylinder 11. The guide rails 12 are arranged parallel to the piston rod of the linear cylinder 11. The slider 13 cooperates with the guide rail 12 slider 13. The top of the slider 13 is fixedly connected to the movable plate 9. The pusher 14 is fixed in the middle of the movable plate 9. One end of the pusher 14 is fixedly cooperated with the piston rod of the linear cylinder 11. The structure of the linear cylinder 11 with double guide rails 12 and slider 13 distributes the lateral pushing force to the two guide rails 12. The movable plate 9 moves smoothly without shaking. When multiple thin plates are pushed out simultaneously, the edges remain in a straight line. The repeatability positioning accuracy is determined by the rigidity of the cylinder stroke. The manual alignment error is completely eliminated. In addition, the cylinder has a built-in speed regulating valve, which can steplessly adjust the pushing speed according to the length and weight of the plate, avoiding scratches on the plate surface caused by sudden stop and rebound.

[0015] In this embodiment, it is further preferred that each of the cylinders 2 has a drive shaft 15 at its center, and bearings are connected to both ends of the drive shaft 15. Each bearing is engaged with a bearing seat 16 on the frame of the roller conveyor line 1. The drive shaft 15 is also connected to a sprocket. Several sprockets are synchronously driven by a chain. The chain locks all the sprockets into one piece, and the rotation speed of all cylinders 2 is synchronized instantly. When the plate is fed longitudinally, the tension of each sprocket is completely consistent, thus preventing misalignment between plates caused by the difference in the speed of the rollers.

[0016] In this embodiment, it is further preferred that the base plate of the T-shaped positioning seat 7 is symmetrically provided with bolt holes on both sides. The base plate of the T-shaped positioning seat 7 is fixedly connected to the longitudinal plate 6 by bolt connection. The bolt connection ensures that the positioning seat is stable and does not loosen when bearing the weight of the plate and the thrust of the push rod 10, providing a solid support foundation for the entire lifting and pushing operation. It can be quickly replaced individually without scrapping the whole component, reducing the maintenance cost and time in the later stage.

[0017] In a further preferred embodiment, a positioning plate 18 is also included. A cover 17 is provided on one side of the frame. The cover 17 covers the sprocket drive structure inside, and can completely enclose the sprocket, chain and other transmission components, effectively preventing the operator's clothing or body parts from being caught. The positioning plate 18 is arranged longitudinally and located on one side of the roller. The bottom of the positioning plate 18 is provided with a limiting groove 19, which is adapted to the width of the pallet 8. The positioning plate 18 is fixed to the cover 17 by an adjusting plate. The positioning plate 18 provides a vertical limit for the lifting pallet 8 system.

[0018] In practice, the sheet material first enters the roller conveyor line 1 from the previous process. Driven by the synchronously driven cylinder 2, it is longitudinally fed into the equipment. When the sheet material reaches the predetermined position, the lifting cylinder is activated, pushing the lifting plate 4 and the entire lifting mechanism to rise. Several support plates 8 fixed on the longitudinal plate 6 smoothly push multiple sheets of material away from the roller through the staggered gaps. Then, the transverse pushing mechanism is activated. The linear cylinder 11 drives the movable plate 9, which drives the L-shaped push rod 10 hidden in the gap to move laterally in sync, pushing the lifted sheet material as a whole to the loading station of the honeycomb molding equipment. After loading is completed, the lifting cylinder descends, and the support plate 8 and push rod 10 return to below the gap of the cylinder 2. The equipment returns to standby mode, waiting for the next cycle.

[0019] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
