Description

Technical Field

[0001] The invention belongs to the technical field of palletizing, and in particular relates to a core board blanking and palletizing device for plywood production. Background Art

[0002] Plywood is a composite material made of multiple layers of thin wood sheets bonded together with glue. The core of the plywood board is typically made of multiple layers of wood veneers bonded together with glue, creating a strong, lightweight composite material. Proper stacking of the core board improves logistics efficiency and reduces losses, making it an indispensable component of modern supply chain management.

[0003] In actual use, it was found that the unloading and palletizing operations rely on multiple drive sources to control different functional modules such as feeding, unloading, and height adjustment. This multi-drive source setup not only significantly increases the cost of the equipment, but also makes the coordinated operation of multiple drive sources prone to failure, greatly affecting the stability and reliability of the equipment operation. In addition, during the plywood stacking process, as the plywood is continuously unloaded and stacked on the pallet, the height of the plywood stack will continue to rise. When the plywood stacks are stacked too high, the stacking difficulty increases significantly, the operation is inconvenient for workers, and it is easy to cause uneven stacking. At the same time, the stability of the plywood stacks that are too high decreases, and there is a safety risk of collapse, which poses a great threat to production safety.

[0036] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0037] Example 1:

[0038] like Figures 1 to 8 As shown, a core board blanking and stacking device for plywood production includes a base plate 1, an operating plate 12, and two pairs of guide frames 11 installed on the base plate 1 at different heights.

[0039] A feeding assembly for conveying plywood is installed at the bottom of the operating panel 12. The feeding assembly includes an adjusting roller 2 with a combination groove 22 and a push plate 24 sliding on the combination groove 22. The combination groove 22 is composed of a feeding groove 221 and a discharge groove 222. The unique combination design of the feeding groove 221 and the discharge groove 222 enables the adjusting roller 2 to accurately control the movement trajectory of the push plate 24 during the rotation process, thereby realizing orderly feeding and unloading operations of the plywood.

[0040] A discharge assembly for unloading is installed on the adjusting roller 2, and the discharge assembly includes a turntable 3 installed on the adjusting roller 2 and a push rod 32 sliding on the bottom of the turntable 3. A notch 31 corresponding to the unloading trough 222 is opened on the surface of the turntable 3, and the top of the push rod 32 is connected to the bottom of the pushing plate 24; this structural design enables the plywood to be accurately unloaded by rotating the turntable 3 and utilizing the cooperation between the push rod 32 and the notch 31 when the plywood is transported to a specific position, thereby ensuring the accuracy and efficiency of the unloading process.

[0041] A downward movement assembly is mounted on the base plate 1. This assembly includes a screw shaft 4 that drives the plywood stack downward. A driven bevel gear 41 is mounted on the screw shaft 4. The sidewall of the driven bevel gear 41 meshes with a driving bevel gear 411 mounted at the rotation center of the adjustment roller 2. The driven bevel gear 41 is a half gear, and its teeth align with the feed trough 221. This design allows the screw shaft 4 to rotate simultaneously with the adjustment roller 2 to feed the plywood. This allows the height of the plywood stack to be automatically adjusted, facilitating subsequent stacking operations.

[0042] like Figures 1 to 8 As shown, in a specific embodiment, a pair of short guide frames 11 are equipped with guide plates 111 on top, and the guide plates 111 are in an inclined state. This inclined design can effectively guide the direction of the plywood during movement, ensuring that the plywood can move smoothly along the predetermined path when it is transferred from the push plate 24 to the guide frame 11, avoiding deviation or falling, and improving the stability of the feeding process. Four support legs 121 are installed at the bottom corners of the operating panel 12, and the bottoms of the four support legs 121 are welded to the surface of the base plate 1. The base plate 1 is in the shape of a "J", and mounting holes are provided on the base plate 1. The base plate 1 is in the shape of a "J", and this shape design not only enhances the overall stability of the device, but also provides a solid foundation for the installation of other components. At the same time, the mounting holes provided on the base plate 1 make it convenient to fix the device to a designated position in the production workshop through bolts and other connectors, ensuring that the device will not be displaced by external forces during the plywood unloading and stacking process.

[0043] Example 2:

[0044] The difference between Example 1 and this example is that: Figures 1 to 8As shown, a transmission shaft 211 is mounted at the center of rotation of the adjustment roller 2. A drive motor 21 is mounted at one end of the transmission shaft 211. The housing of the drive motor 21 is mounted at the bottom of the operating panel 12. A positioning seat 212 is rotatably mounted on the transmission shaft 211 and welded to the bottom of the operating panel 12. The end of the transmission shaft 211 is interconnected with the center of rotation of the drive bevel gear 411. The drive motor 21 provides the power source for the operation of the entire device, while the positioning seat 212 ensures the stability of the transmission shaft 211 during rotation, allowing the adjustment roller 2 to rotate smoothly and ensuring the precise execution of the feeding and unloading operations. Simultaneously, the power of the drive motor 21 is transmitted to the drive bevel gear 411 via the transmission shaft 211, enabling the coordinated operation of the feeding assembly and the lowering assembly.

[0045] like Figures 1 to 8 As shown, in a specific embodiment, the feed trough 221 is a spiral trough, the discharge trough 222 is a linear trough, a slide rod 234 is slidably provided inside the combined trough 22, a push block 23 is mounted on top of the slide rod 234, and the push block 23 is horizontally slidably provided in the operating panel 12. A through slot 231 is transversely provided inside the operating panel 12, and the push block 23 is slidably provided in the through slot 231. A guide rod 232 is movably provided inside the push block 23, and both ends of the guide rod 232 are mounted on the side walls of the through slot 231. A compression spring 233 is sleeved on the guide rod 232, and one end of the compression spring 233 is clamped to the side wall of the through slot 231, and the other end of the compression spring 233 is clamped to the side wall of the push block 23. The guide rod 232 provides a stable guide for the movement of the pushing block 23, ensuring that the sliding direction of the pushing block 23 in the through groove 231 is accurate to avoid deviation. The compression spring 233 plays a buffering and resetting role during the movement of the pushing block 23. When the pushing block 23 is pushed by an external force, the compression spring 233 is compressed to store energy. After the feeding action is completed, the compression spring 233 releases energy, pushing the pushing block 23 to reset and prepare for the next feeding.

[0046] like Figures 1 to 8 As shown, further, a synchronous bracket 246 is installed on the pushing block 23, and three pressure plates 245 are installed on the top of the synchronous bracket 246. The three pressure plates 245 are all movably penetrated and inserted with a positioning rod 242. Fixed platforms 243 are installed at both ends of the positioning rod 242. A fixed plate 241 is installed on the back of the fixed platform 243. The fixed plate 241 is welded and set on the pushing plate 24. A positioning spring 244 is sleeved on the positioning rod 242. One end of the positioning spring 244 is clamped on the pressure plate 245, and the other end of the positioning spring 244 is clamped on the fixed platform 243. The positioning spring 244 ensures that the pushing plate 24 always has a downward force.

[0047] Example 3:

[0048] The difference between Example 2 and this example is that: Figures 1 to 8 As shown, a mounting bracket 321 is fixedly provided on the push rod 32, and a guide wheel 322 is provided on the mounting bracket 321. The guide wheel 322 is attached to the surface of the turntable 3. The push rod 32 movably passes through the operating panel 12, and a slider 323 is installed on the top of the push rod 32. A synchronization rod 324 is movably installed inside the slider 323. Synchronization seats 325 are installed at both ends of the synchronization rod 324, and the synchronization seats 325 are welded to the bottom of the operating panel 12. The cooperation between the slider 323 and the synchronization rod 324 limits the movement direction of the push rod 32, so that it can only move up and down in the vertical direction, ensuring that the push plate 24 can descend vertically during the unloading process, avoiding the unloading of plywood caused by the deviation of the push rod 32.

[0049] like Figures 1 to 8 As shown, in a specific embodiment, a reset cover 33 is installed at the bottom of the operating panel 12, and the top rod 32 movably passes through the reset cover 33. A reset plate 331 is slidably provided inside the reset cover 33. The reset plate 331 and the top rod 32 are connected to each other, and a reset spring 332 is sleeved on the top rod 32. One end of the reset spring 332 is clamped on the bottom of the reset cover 33, and the other end of the reset spring 332 is clamped on the reset plate 331.

[0050] like Figures 1 to 8 As shown, the top of the screw shaft 4 is rotatably connected to the base plate 1, and a screw sleeve 42 is meshedly mounted on the screw shaft 4. A synchronization frame 43 is mounted on the side wall of the screw sleeve 42. A lifting platform 431 is mounted on the end of the synchronization frame 43. A tray 432 is overlapped on the top of the lifting platform 431, and the tray 432 slides on the inner walls of the two pairs of guide frames 11. A slide 421 is mounted on the side wall of the screw sleeve 42. A limit rod 422 is movably installed inside the slide 421. The bottom of the limit rod 422 is welded to the base plate 1, and the limit rod 422 and the screw shaft 4 are parallel to each other. A limit plate 423 is mounted on the top of the limit rod 422. The diameter of the limit plate 423 is larger than that of the limit rod 422. The meshing transmission between the screw shaft 4 and the screw sleeve 42 precisely controls the height of the pallet 432. As plywood sheets are continuously stacked on the pallet 432, the pallet 432 can be steadily lowered under the drive of the screw shaft 4, always maintaining the appropriate height, facilitating the subsequent plywood stacking operation. The cooperation between the slide plate 421 and the limit rod 422 provides a stable guide for the movement of the screw sleeve 42, preventing the screw sleeve 42 from rotating or deflecting during movement, ensuring that the pallet 432 can be raised and lowered vertically. The provision of the limit plate 423 prevents the screw sleeve 42 from disengaging from the screw shaft 4 due to excessive movement, ensuring the safety and stability of the device operation.

[0051] The implementation principle of the core board blanking and stacking device for plywood production of the present invention is as follows:

[0052] The plywood after production can be placed on the surface of the pushing plate 24, and then the operator can start the driving motor 21, which drives the transmission shaft 211 to rotate, thereby causing the adjusting roller 2 to start rotating. As the adjusting roller 2 rotates (in Figure 8 As a basis, the adjusting roller 2 rotates counterclockwise), the position of the combination groove 22 in the adjusting roller 2 changes, and then the position of the feeding groove 221 in the combination groove 22 changes, and at this time the slide bar 234 at the bottom of the pushing block 23 slides in the feeding groove 221, so when the position of the feeding groove 221 changes, the pushing block 23 can slide back and forth inside the through groove 231.

[0053] When the pushing block 23 slides, the pushing block 23 slides along the guide rod 232, and the guide rod 232 plays a guiding role. At the same time, the compression spring 233 is compressed synchronously, and the compression spring 233 facilitates the subsequent reset operation.

[0054] When the pushing block 23 slides, the pushing plate 24 is driven to slide by the synchronous bracket 246 and the fixed plate 241, and then the pushing plate 24 can drive the plywood on the surface to move. The plywood first moves from the top of the pair of guide frames 11 with a shorter height. The guide plate 111 installed on the top of the guide frame 11 is in an inclined state, which can guide the moving direction of the plywood and ensure that the plywood remains stable during the movement without tilting or offsetting. As the pushing plate 24 continues to move, the plywood can eventually be completely moved above the two pairs of guide frames 11.

[0055] During the movement of the above structure, the turntable 3 on the adjusting roller 2 also rotates synchronously. In the initial state, the guide wheel 322 on the mounting bracket 321 fixedly arranged at the bottom of the top rod 32 slides in the notch 31 of the turntable 3. When the cam 32 is in the process of being moved down, the cam 323 of the cam 32 is moved downwards, and the cam 324 of the cam 32 is in the process of being moved downwards, so that the cam 323 of the cam 32 can move downwards. When the pushing plate 24 returns to its initial position, the notch 31 on the turntable 3 can just correspond to the push rod 32 and the mounting bracket 321. At this time, the reset spring 332 rebounds quickly, pushing the reset plate 331 and the push rod 32 to return upward, thereby driving the pushing plate 24 to return to its initial height, ready to receive the next piece of plywood.

[0056] When the adjusting roller 2 is continuously rotating, the driving bevel gear 411 can rotate synchronously. When the feeding trough 221 drives the pushing block 23 and the pushing plate 24 to slide, the teeth of the driven bevel gear 41 begin to mesh with the driving bevel gear 411. Since the driven bevel gear 41 is a half gear and its teeth are adapted to the position of the feeding trough 221, during the meshing process, the screw shaft 4 begins to rotate. The top of the screw shaft 4 is installed with the base plate 1 through a rotational connection to ensure that the screw shaft 4 can rotate stably. The rotation of the screw shaft 4 drives the screw sleeve 42 engaged therewith to move downward along the axial direction of the screw shaft 4. The synchronous frame 43 installed on the side wall of the screw sleeve 42 will move downward synchronously with the movement of the screw sleeve 42. The lifting platform 431 installed at the end of the synchronous frame 43 drives the tray 432 to descend. As the number of plywood on the tray 432 continues to increase, the tray 432 continues to descend under the drive of the screw shaft 4, always maintaining a suitable height to facilitate the subsequent stacking of plywood.
