Description

Technical Field

[0001] This utility model belongs to the field of material frame stacking equipment, and specifically relates to an underground material frame stacking equipment. Background Technology

[0002] Currently, the production and processing of aluminum materials generally adopts extrusion molding. When using this extrusion molding process to produce aluminum materials, the raw materials (usually aluminum rods or ingots, etc.) softened at high temperature are first placed in an extruder, and then extruded through an aluminum extrusion die under strong pressure to form a shape that meets the design requirements. Subsequently, after extrusion molding is completed, the aluminum material needs to be cut into specific lengths and then proceed to subsequent processes such as aging treatment and coating.

[0003] Furthermore, during the transfer of aluminum materials, which are relatively soft and prone to deformation, they need to be placed in a pallet crate for protection. Simultaneously, to reduce the labor intensity of workers and improve the efficiency of pallet stacking, existing aluminum processing production lines are gradually adopting various types of stacking machines to automate the stacking of pallets. For example, Chinese patent CN113955503A discloses an automatic pallet conveying and stacking machine.

[0004] However, since most existing stacking machines use a chain structure at each of the four corners of the lifting frame, the lifting frame is prone to shaking, tilting, or even chain breakage during the lifting process. This can easily cause scratches and other damage to the aluminum material stored in the frame, posing certain safety hazards. This risk is even more pronounced when lifting heavy or large frames. Utility Model Content

[0005] The technical problem solved by this utility model is to provide an underground material frame stacking device that can not only realize the material frame stacking action, but also has the advantages of large load-bearing capacity, high safety and strong stability.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: an underground material frame stacking device, comprising a device base, with at least one stacking module disposed on the upper end of the device base; the stacking module includes a lifting mechanism and a support frame, the lower end of the lifting mechanism is mounted on the device base, and the upper end of the lifting mechanism is provided with a lifting platform; the support frame covers the lifting mechanism, and a rotating support mechanism is disposed in the middle of the support frame. When using this utility model to stack material frames, the lifting platform can first be lowered to a certain height and aligned with the material frame conveying mechanism in the production line, and then the conveying mechanism in the production line can be used to transport the material frame above the lifting platform; then the lifting mechanism can be controlled to raise the lifting platform to a certain height until the material frame reaches the specified stacking height, at which point the rotating support mechanism can be controlled to support the material frame, thereby completing the stacking operation; conversely, when it is necessary to output the stacked material frame, the rotating support mechanism can be controlled to rotate first to release the support of the material frame, and then the conveying mechanism in the production line can be used to output the material frame. Moreover, throughout the process, since this utility model uses a lifting structure to raise and lower the material frame, it has advantages such as high load-bearing capacity, high safety, and strong stability. It is also less prone to shaking during the conveying process, thus effectively preventing the aluminum material from colliding and scratching inside the material frame.

[0007] Furthermore, the support frame includes two columns located in front of the lifting mechanism and two columns located behind the lifting mechanism. Each column is equipped with a rotating support mechanism in the middle, which can both support the material frame and avoid it.

[0008] Furthermore, the rotating support mechanism includes a vertically arranged rotating rod, which is rotatably mounted on the column near the material to be lifted via bearings. At least one material support block is provided in the middle of the rotating rod along the height direction. The end of the rotating rod is connected to a rotating drive mechanism, which controls the rotating rod to rotate, thereby changing the working state of the rotating support mechanism.

[0009] Furthermore, a first crossbeam is connected between the two columns on the right side of the lifting mechanism, and a second crossbeam is connected between the two columns on the left side of the lifting mechanism. The upper end of the rotating rod is rotatably mounted on the corresponding crossbeam. The rotary drive mechanism includes a second power cylinder, the cylinder body of which is mounted on the corresponding crossbeam. A rocker arm is connected to the piston rod end of the second power cylinder. The end of the rocker arm is fixedly connected to the end of the rotating rod and controls the rotating rod in the rotary support mechanism to rotate.

[0010] Alternatively, a first crossbeam is connected between the two columns located on the front side of the lifting mechanism, and a second crossbeam is connected between the two columns located on the rear side of the lifting mechanism. The upper end of the rotating rod is rotatably mounted on the corresponding crossbeam. The rotary drive mechanism includes a second power cylinder, the cylinder body of which is mounted on the corresponding crossbeam. A rocker arm is connected to the piston rod end of the second power cylinder. The end of the rocker arm is fixedly connected to the end of the rotating rod and controls the rotating rod in the rotary support mechanism to rotate.

[0011] Furthermore, the lifting mechanism includes a fixed frame fixedly installed on the equipment base, a top plate is provided above the fixed frame, a scissor lift assembly is provided between the lower end of the top plate and the upper end of the fixed frame, the upper end of the top plate is fixedly connected to the lifting platform, and the top plate and the lifting platform can be controlled to move up and down under the action of the scissor lift assembly.

[0012] Furthermore, the scissor lift assembly includes two parallel scissor arms (II) and two parallel scissor arms (I). The lower ends of the two scissor arms (II) are horizontally slidably mounted on the upper end of the fixed frame, while the lower ends of the two scissor arms (I) are rotatably mounted on the upper end of the fixed frame. A first connecting rod connects the lower ends of the two scissor arms (II) and a second connecting rod connects the lower ends of the two scissor arms (I). The upper ends of the two scissor arms (II) are horizontally slidably mounted on the lower end of the top plate, while the upper ends of the two scissor arms (I) are rotatably mounted on the lower end of the top plate. A third connecting rod connects the upper ends of the two scissor arms (II) and a fourth connecting rod connects the upper ends of the two scissor arms (I). A rotating shaft is rotatably connected to the middle portions of both scissor arms (II) and both scissor arms (I). A first power cylinder connects the third connecting rod and the second connecting rod. Thus, this invention can change the included angle between the two scissor arms (II) and the two scissor arms (I) by the action of the first power cylinder, thereby achieving the purpose of changing the height of the lifting platform.

[0013] Furthermore, a horizontal conveying mechanism is provided at the upper end of the top plate. The horizontal conveying mechanism can contact the material above the lifting platform and convey the material frame horizontally through the horizontal conveying mechanism to adjust the position of the material frame above the lifting platform.

[0014] Furthermore, the horizontal conveying mechanism includes at least two driven shafts arranged parallel to each other along the material conveying direction. All driven shafts are rotatably mounted on the upper end of the top plate. All driven shafts are connected by a transmission assembly, and one of the driven shafts is connected to a drive motor. Each driven shaft has conveying rollers installed at both ends. The conveying rollers extend out of the lifting platform through a conveying window opened on the surface of the lifting platform and can contact the material frame, thereby conveying the material frame horizontally.

[0015] Furthermore, a height limiting post is provided at the upper end of the fixed frame. The upper end of the height limiting post can abut against the lower end of the top plate and limit the minimum height of the top plate and the lifting platform.

[0016] Furthermore, the upper surface of the equipment base is provided with an installation groove, and the lifting mechanism is installed in the installation groove. The lifting platform can be flush with the upper surface of the equipment base under the action of the lifting mechanism, so as to ensure that the material frame can be moved smoothly to the top of the lifting platform; and it can also be higher than the upper surface of the equipment base under the action of the lifting mechanism, so as to achieve the function of lifting the material frame.

[0017] As can be seen from the above technical solutions, this utility model has the following advantages: Compared with existing stacking machines, the underground material frame stacking equipment provided by this utility model can not only realize the stacking action of material frames, but also has the advantages of large load-bearing capacity, high safety and strong stability. Thus, it can ensure the stability of the material frame during the conveying process, making it less prone to shaking, thereby effectively avoiding collision and scratches of aluminum materials in the material frame and ensuring the quality of the conveyed aluminum materials.

[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0025] like Figures 1 to 4 This utility model provides an underground material frame stacking device, which includes a device base 1. The device base 1 is installed inside a foundation, and the upper end of the device base 1 is flush with the foundation. Simultaneously, this utility model provides a mounting groove on the upper surface of the device base 1, and at least one stacking module is disposed within the mounting groove.

[0026] The stacking module includes a lifting mechanism 2 and a support frame 5. The lifting mechanism 2 includes a fixed frame 7 fixedly installed in the mounting groove of the equipment base 1. A top plate 8 is provided above the fixed frame 7, and a scissor lift assembly is provided between the lower end of the top plate 8 and the upper end of the fixed frame 7. A lifting platform 9 is provided at the upper end of the top plate 8, and the top plate 8 and the lifting platform 9 can be controlled to move up and down under the action of the scissor lift assembly.

[0027] Specifically, such as Figure 2 , Figure 3 As shown, the scissor lift assembly includes two parallel scissor arms 10 and two parallel scissor arms 11. The lower ends of the two scissor arms 10 are horizontally slidably mounted on the upper end of the fixed frame 7, and the lower ends of the two scissor arms 11 are rotatably mounted on the upper end of the fixed frame 7. A first connecting rod connects the lower ends of the two scissor arms 10, and a second connecting rod connects the lower ends of the two scissor arms 11. The upper ends of the two scissor arms 10 are horizontally slidably mounted on the lower end of the top plate 8, and the upper ends of the two scissor arms 11 are rotatably mounted on the lower end of the top plate 8. A third connecting rod connects the upper ends of the two scissor arms 10, and a fourth connecting rod connects the upper ends of the two scissor arms 11. Rotating shafts are rotatably connected to the middle portions of both the two scissor arms 10 and the two scissor arms 11. A first power cylinder 13 connects the third connecting rod and the second connecting rod. In this way, the present invention can change the included angle between the two scissor arms 10 and the two scissor arms 11 by the action of the first power cylinder 13, thereby achieving the purpose of changing the height of the lifting platform 9.

[0028] A horizontal conveying mechanism is provided between the upper end of the top plate 8 and the lower end of the lifting platform 9. The horizontal conveying mechanism includes at least two driven shafts arranged parallel to each other along the material conveying direction. All driven shafts are rotatably mounted on the upper end of the top plate 8, and all driven shafts 14 are connected by transmission components 15 such as chain drive structure and belt drive structure. One of the driven shafts 14 is connected to a drive motor. Each driven shaft 14 has a conveying roller 16 installed at both ends. The conveying roller 16 extends out of the lifting platform 9 through a conveying window opened on the surface of the lifting platform 9 and can contact the material frame 3, thereby conveying the material frame 3 horizontally to adjust the position of the material frame 3 above the lifting platform 9.

[0029] Meanwhile, as a preferred embodiment, the present invention may also provide a height limiting post 12 at the upper end of the fixed frame 7. The upper end of the height limiting post 12 can abut against the lower end of the top plate 8 and limit the minimum height of the top plate 8 and the lifting platform 9.

[0030] like Figure 1 , Figure 4 As shown, the support frame 5 is installed above the lifting mechanism 2, and the support frame 5 includes two columns located in front of the lifting mechanism 2 and two columns located behind the lifting mechanism 2. A first crossbeam is connected between the two columns located on the right side of the lifting mechanism 2, and a second crossbeam is connected between the two columns located on the left side of the lifting mechanism 2. A rotating support mechanism is provided in the middle of each column, so as to support the material frame 3 during the stacking process and avoid the material frame 3 during the conveying process.

[0031] Specifically, the rotating support mechanism includes a vertically arranged rotating rod 20, which is rotatably mounted on a column near the material to be lifted via bearings. At least one material support block 19 is provided along the height direction at the middle of the rotating rod 20. The end of the rotating rod 20 is rotatably mounted on a crossbeam via a bearing seat 18, and the end of the rotating rod 20 passes through the corresponding crossbeam and is connected to a rotating drive mechanism 6. The rotating drive mechanism 6 includes a second power cylinder 17, the cylinder body of which is mounted on the corresponding crossbeam. A rocker arm is connected to the piston rod end of the second power cylinder 17, and the end of the rocker arm is fixedly connected to the end of the rotating rod 20. The second power cylinder 17 controls the rotation of the rocker arm and the rotating rod 20 to change the working state of the rotating support mechanism.

[0032] In addition to the above structure, the two crossbeams can also be set between the two columns located in front of the lifting mechanism 2 and between the two columns located behind the lifting mechanism 2, which can also meet the above working requirements.

[0033] Based on this, when using this utility model to stack the material frame 3, the lifting platform 9 can be lowered to a certain height and aligned with the material frame 3 conveying mechanism in the production line. Then, the material frame 3 is conveyed to the top of the lifting platform 9 using the conveying mechanism in the production line and the horizontal conveying mechanism provided at the lifting platform 9. Next, the lifting mechanism 2 is controlled to raise the lifting platform 9 to a certain height until the material frame 3 reaches the specified stacking height. Then, the rotating support mechanism can be controlled to support the material frame 3, thereby completing the stacking operation of the material frame 3. Conversely, when it is necessary to output the stacked material frame 3, the rotating support mechanism can be controlled to rotate first to release the support of the material frame 3, and then the material frame 3 can be output using the horizontal conveying mechanism provided at the lifting platform 9 and the conveying mechanism in the production line.
