Description

Technical Field

[0001] This utility model relates to the technical field of stacking support frames, and more particularly to an anti-deformation stacking support frame for MDF stacking. Background Technology

[0002] Medium-density fiberboard (MDF) is a type of engineered wood product made from wood fibers or other plant fibers through a process of crushing, fiberizing, drying, gluing, and high-temperature, high-pressure pressing. It has a uniform structure, a smooth and flat surface, a dense and stable texture, is impact-resistant, and easy to process, making it suitable for cutting, drilling, and carving. It is widely used in furniture manufacturing, interior decoration, flooring substrates, door panels, and packaging. However, MDF has poor water resistance and is not suitable for use in humid environments. It also has relatively weak nail-holding power, requiring moisture-proofing measures during use.

[0003] Currently available anti-deformation stacking support frames for MDF (medium-density fiberboard) typically employ a top-down, unidirectional access method in their structural design. While this design ensures the stability of the MDF during stacking and prevents deformation caused by gravity or external forces, it has significant limitations in practical use. When it is necessary to prioritize accessing the MDF in the lower layers of the stack, all the upper layers must be removed one by one. This not only increases the number of steps and time costs but may also cause scratches on the surface or edge damage to the boards during repeated handling. Especially in scenarios involving frequent access in mass production or warehouse management, this unidirectional access method severely reduces work efficiency and fails to meet the actual needs for flexible access. Utility Model Content

[0004] In view of the fact that the existing technology cannot directly remove the lower layer without removing the upper layer, resulting in low access efficiency and cumbersome operation, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an anti-deformation stacking support frame for MDF stacking, which aims to solve the problem that the existing technology cannot directly remove the lower layer of board without removing the upper layer of board, resulting in low storage and retrieval efficiency and cumbersome operation.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a deformation-resistant stacking support frame for MDF stacking, including a main frame, a bearing mechanism, and a centering mechanism. The bearing mechanism includes a bearing plate movably installed inside the main frame. Slide rails are provided on both sides of the main frame. A fixing plate is fixedly installed inside the slide rail. Tooth blocks are fixedly installed on the surface of the fixing plate. Transmission gears are rotatably installed on both sides of the bearing plate via a rotating shaft. A handwheel is rotatably installed on one side of the bearing plate via a rotating rod. The centering mechanism includes centering plates that are movably mounted on both sides of the upper surface of the support plate.

[0007] As a preferred embodiment of the anti-deformation stacking support frame for MDF stacking described in this utility model, the upper surface of the bearing plate is provided with a T-shaped groove, and the rotating shaft and rotating rod are rotatably installed inside the T-shaped groove.

[0008] As a preferred embodiment of the anti-deformation stacking support frame for MDF stacking described in this utility model, the transmission gear meshes with the fixed plate through a toothed block.

[0009] As a preferred embodiment of the anti-deformation stacking support frame for MDF stacking described in this utility model, a first bevel gear is fixedly installed on the surface of the rotating shaft, and a second bevel gear is fixedly installed at one end of the rotating rod, with the first bevel gear and the second bevel gear meshing with each other.

[0010] As a preferred embodiment of the anti-deformation stacking support frame for MDF stacking described in this utility model, a limiting groove is formed on the inner surface of the bearing plate, and a limiting rod is fixedly installed inside the limiting groove.

[0011] As a preferred embodiment of the anti-deformation stacking support frame for MDF stacking described in this utility model, wherein: a limiting block is slidably installed on the surface of the limiting rod, a spring structure is installed between one side surface of the limiting block and the inner wall of the limiting groove, and the limiting block is fixedly installed on both sides of the centering plate.

[0012] As a preferred embodiment of the anti-deformation stacking support frame for MDF stacking described in this utility model, a number of ventilation holes are provided through the rear surface of the main frame.

[0013] As a preferred embodiment of the anti-deformation stacking support frame for MDF stacking described in this utility model, a sliding rod is fixedly installed on the inner surface of the main frame, and the bearing plate is slidably installed on the surface of the sliding rod.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model, through its designed support mechanism, allows for the removal of the lower-layer MDF from the main frame when the handwheel is turned. This causes the rotating rod to rotate, which in turn rotates the first bevel gear and the rotating shaft, ultimately causing the transmission gear to rotate. The transmission gear meshes with the toothed blocks on the surface of the fixed plate, thereby sliding the entire support plate outward and causing the MDF loaded on the surface of the support plate to slide outward from the main frame. This achieves the goal of directly storing and retrieving any layer of MDF without moving the upper layer of boards, greatly simplifying the operation process, significantly improving storage and retrieval efficiency, and effectively avoiding accidental damage to the boards during repeated handling.

[0015] 2. This utility model, through its centering mechanism, applies pressure to the limiting block towards the center when the MDF is stacked on the upper surface of the support plate. This pressure is applied by the spring structure, causing the centering plate to be squeezed towards the center, thus keeping the MDF stacked on the support plate in the center position. This ensures the neatness and stability of the stacked boards, effectively preventing the risk of tilting or collapse caused by eccentric placement. It provides a reliable guarantee for smooth sliding out and safe transportation, and improves the overall safety and convenience of use. Attached Figure Description

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0019] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a deformation-resistant stacking support frame for MDF stacking. The MDF stacking support frame includes a main frame 1, a bearing mechanism 2, and a centering mechanism 3. The bearing mechanism 2 includes a bearing plate 201 movably installed inside the main frame 1. Slide rails 202 are provided on both sides of the interior of the main frame 1. A fixing plate 203 is fixedly installed inside the slide rail 202. A toothed block 204 is fixedly installed on the surface of the fixing plate 203. Transmission gears 205 are rotatably installed on both sides of the bearing plate 201 through a rotating shaft 206. A handwheel 210 is rotatably installed on one side of the bearing plate 201 through a rotating rod 209.

[0020] The upper surface of the bearing plate 201 is provided with a T-slot, and the rotating shaft 206 and the rotating rod 209 are rotatably installed inside the T-slot.

[0021] The transmission gear 205 meshes with each other through the tooth block 204 and the fixed plate 203.

[0022] A first bevel gear 207 is fixedly mounted on the surface of the rotating shaft 206, and a second bevel gear 208 is fixedly mounted on one end of the rotating rod 209. The first bevel gear 207 and the second bevel gear 208 mesh with each other.

[0023] During use, when a specific layer of MDF needs to be removed, the operator turns the handwheel 210. The handwheel 210 drives the rotating rod 209 to rotate, and the second bevel gear 208 at the end of the rotating rod 209 rotates accordingly and meshes with the first bevel gear 207, transmitting power to the rotating shaft 206 perpendicular to it. The rotation of the rotating shaft 206 drives the transmission gears 205 at both ends to rotate synchronously. Since the transmission gears 205 mesh with the toothed blocks 204 fixed on the surface of the fixed plate 203 inside the slide rail 202 of the main frame 1, the rotational motion of the transmission gears 205 is converted into the linear translational motion of the bearing plate 201 along the slide rail 202. The bearing plate 201 is installed in the T-slot through the rotating shafts 206 and the rotating rod 209 on both sides, ensuring the stability and accuracy of the movement. Finally, the bearing plate 201 and the MDF stacked on it are smoothly slid out from inside the main frame 1 until they are completely exposed, making it convenient for the operator to take them directly. Example 2

[0024] Reference Figures 3-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the centering mechanism 3 includes centering plates 305 that are movably installed on both sides of the upper surface of the support plate 201.

[0025] A limiting groove 301 is formed on the inner surface of the bearing plate 201, and a limiting rod 302 is fixedly installed inside the limiting groove 301.

[0026] A limiting block 303 is slidably mounted on the surface of the limiting rod 302. A spring structure 304 is installed between one side surface of the limiting block 303 and the inner wall of the limiting groove 301. The limiting block 303 is fixedly mounted on both sides of the centering plate 305.

[0027] Several sets of ventilation holes 4 are provided through the rear surface of the main frame 1.

[0028] A slide bar 5 is fixedly installed on the inner surface of the main frame 1, and a bearing plate 201 is slidably installed on the surface of the slide bar 5.

[0029] During use, when the MDF is placed on the support plate 201, the centering mechanism 3 starts working. The operator pushes the board to one side of the support plate 201, and the centering plate 305 on that side pushes the limiting block 303 to slide on the limiting rod 302 in the limiting groove 301 and compresses the spring structure 304. Subsequently, when the board is pushed to the other side, the spring structure 304 on that side is also compressed. When the external force is removed, the elastic restoring force of the spring structures 304 on both sides will simultaneously push their respective limiting blocks 303 and centering plates 305 to move to the middle position, thereby automatically clamping and positioning the MDF in the center of the support plate 201. During the entire movement of the support plate 201, its bottom is slidably connected to the inner side of the main frame 1 through the slide rod 5, providing additional support and guidance to ensure the smoothness of the movement. At the same time, the ventilation hole 4 on the rear side of the main frame 1 ensures air circulation of the stacked boards, which helps to prevent moisture and deformation.

[0030] The remaining structure is the same as that in Example 1.

[0031] Based on embodiments 1-2, the working principle of this utility model is as follows: When the board is placed on the support plate 201, the spring structures 304 on both sides of the centering mechanism 3 push the centering plate 305 towards the center through the limiting blocks 303, automatically centering the MDF and ensuring neat and stable stacking, laying the foundation for subsequent operations. When it is necessary to remove any layer of MDF, the operator only needs to turn the handwheel 210, and the power is transmitted to the second bevel gear 208 through the rotating rod 209, which in turn meshes with the first bevel gear 207, causing the rotating shaft 206 connected to it to rotate. The rotation of the rotating shaft 206 drives the transmission gears 205 at both ends to rotate. The transmission gears 205 and the toothed blocks 205 fixed on the main frame 1 rotate together. 4. Engagement precisely converts the rotational motion into the linear translational motion of the support plate 201. During this process, the sliding rod 5 at the bottom of the support plate 201 slides inside the main frame 1, providing additional support and guidance, ensuring the smooth and reliable movement of the entire process. Finally, the support plate 201, along with the MDF board that has been centered on it, is smoothly slid out from inside the main frame 1, achieving the goal of direct access without moving the upper layer of boards. The entire process not only greatly improves the storage and retrieval efficiency and avoids damage to the boards during handling, but also ensures good ventilation of the stacked boards through the ventilation holes 4 on the rear side of the main frame 1, effectively preventing moisture deformation and comprehensively improving the convenience, safety, and practicality of the equipment.
