Description

Technical Field

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

[0002] Plywood is a composite material formed by bonding multiple thin wood boards with glue. The core board of plywood is the core part of plywood, usually formed by bonding multiple thin wood slices with glue to form a composite material with high strength and light weight. Reasonable palletizing of the core board can improve logistics efficiency and reduce losses, and is an indispensable part of modern supply chain management.

[0003] In actual use, it is found that the blanking and palletizing operation controls different functional modules such as feeding, discharging, and height adjustment through multiple drive sources respectively. This setting of multiple drive sources not only greatly increases the cost investment of the equipment, but also the coordinated operation of multiple drive sources is prone to failures, which greatly affects the stability and reliability of the equipment operation. And during the stacking process of plywood, as the plywood is continuously blanked and stacked on the pallet, the height of the plywood stack will continue to rise. When the plywood stack is stacked too high, the stacking difficulty increases significantly, it is inconvenient for workers to operate, and it is easy to cause uneven stacking; at the same time, the stability of the too-high plywood stack decreases, and there is a safety risk of collapse, which poses a great threat to production safety.

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0037] Embodiment 1:

[0038] As Figures 1 to 8 shown, a core board cutting and stacking device for plywood production includes a substrate 1, an operation plate 12, and two pairs of guide frames 11 with different heights installed on the substrate 1.

[0039] At the bottom of the operation panel 12, a feeding component for conveying plywood is installed. The feeding component includes an adjusting roller 2 with a combined groove 22 and a pushing plate 24 sliding on the combined groove 22. The combined groove 22 is composed of a feeding groove 221 and a discharging groove 222. The unique combined design of the feeding groove 221 and the discharging groove 222 enables the adjusting roller 2 to accurately control the movement trajectory of the pushing plate 24 during rotation, realizing the orderly feeding and discharging operations of plywood.

[0040] An unloading component for discharging materials is installed on the adjusting roller 2. The unloading component includes a turntable 3 installed on the adjusting roller 2 and a ejector rod 32 sliding at the bottom of the turntable 3. A notch 31 corresponding to the discharging groove 222 is opened on the surface of the turntable 3, and the top of the ejector rod 32 is connected to the bottom of the pushing plate 24. This structural design enables the plywood to be accurately discharged through the rotation of the turntable 3 and the cooperation of the ejector rod 32 and the notch 31 when the plywood is conveyed to a specific position, ensuring the accuracy and efficiency of the discharging process.

[0041] A downward movement component is installed on the base plate 1. The downward movement component includes a lead screw shaft 4 for driving the plywood stack to move downward. A driven bevel gear 41 is installed on the lead screw shaft 4, and the side wall of the driven bevel gear 41 meshes with a driving bevel gear 411 installed at the rotation center of the adjusting roller 2. The driven bevel gear 41 is a semi-gear and the teeth are adapted to the position of the feeding groove 221. Such a design enables the lead screw shaft 4 to be driven to rotate through the meshing relationship of the bevel gears while the adjusting roller 2 rotates for feeding, thereby realizing the automatic adjustment of the height of the plywood stack and facilitating the subsequent stacking operation of plywood.

[0042] As Figures 1 to 8 shown, in the specific implementation, guide plates 111 are installed at the tops of a pair of guide frames 11 with a lower height. 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 transferring from the pushing plate 24 to the guide frames 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 operation panel 12. The bottoms of the four support legs 121 are welded to the surface of the base plate 1. The base plate 1 is in a U-shape, and mounting holes are opened on the base plate 1. The U-shape of the base plate 1 not only enhances the overall stability of the device but also provides a stable foundation for the installation of other components. At the same time, the mounting holes opened on the base plate 1 facilitate the fixing of the device at a designated position in the production workshop through connecting parts such as bolts, ensuring that the device will not be displaced due to external forces during the plywood discharging and stacking process.

[0043] Embodiment 2:

[0044] Based on Embodiment 1, the difference from this embodiment is: As Figures 1 to 8As shown, a transmission shaft 211 is installed at the rotation center of the adjusting roller 2, a driving motor 21 is installed at one end of the transmission shaft 211, the housing of the driving motor 21 is installed at the bottom of the operating panel 12, a positioning seat 212 is rotatably installed on the transmission shaft 211, the positioning seat 212 is welded to the bottom of the operating panel 12, and the end of the transmission shaft 211 is connected to the rotation center of the driving bevel gear 411. The setting of the driving motor 21 provides a power source for the operation of the entire device, and the positioning seat 212 ensures the stability of the transmission shaft 211 during the rotation process, so that the adjusting roller 2 can rotate smoothly, ensuring the accurate execution of the feeding and unloading actions. At the same time, the power of the driving motor 21 is transmitted to the driving bevel gear 411 through the transmission shaft 211, realizing the coordinated work of the feeding component and the downward moving component.

[0045] like Figures 1 to 8 As shown, in a specific embodiment, the feed slot 221 is a spiral slot, the discharge slot 222 is a linear slot, a slide bar 234 is slidably arranged inside the combined slot 22, a push block 23 is installed on the top of the slide bar 234, and the push block 23 is horizontally slidably arranged in the operating panel 12. A through slot 231 is horizontally opened inside the operating panel 12, and the push block 23 is slidably arranged in the through slot 231. A guide rod 232 is movably installed inside the push block 23, and both ends of the guide rod 232 are installed on the side wall 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 on the side wall of the through slot 231, and the other end of the compression spring 233 is clamped on the side wall of the push block 23. The guide rod 232 provides a stable guiding effect for the movement of the push block 23, ensuring that the sliding direction of the push 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 push block 23. When the push 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 and pushes the push block 23 to reset, preparing 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 positioning rods 242. Fixed platforms 243 are installed at both ends of the positioning rods 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] Embodiment 3:

[0048] The difference between Example 2 and this example is that:Figures 1 to 8 As shown, an installation frame 321 is fixedly arranged on the ejector rod 32. A guide wheel 322 is arranged on the installation frame 321. The guide wheel 322 is attached to the surface of the turntable 3. The ejector rod 32 movably penetrates through the operation plate 12. A slider 323 is installed at the top of the ejector rod 32. A synchronizing rod 324 is movably penetrated through the slider 323. Synchronizing seats 325 are installed at both ends of the synchronizing rod 324. The synchronizing seats 325 are welded to the bottom of the operation plate 12. The cooperation between the slider 323 and the synchronizing rod 324 restricts the moving direction of the ejector rod 32, enabling it to move vertically up and down only, ensuring that during the unloading process, the pushing plate 24 can descend vertically, and avoiding the unsmooth unloading of the plywood due to the deviation of the ejector rod 32.

[0049] As Figures 1 to 8 shown, in the specific implementation, a reset cover 33 is installed at the bottom of the operation plate 12. The ejector rod 32 movably penetrates through the reset cover 33. A reset plate 331 is slidably arranged inside the reset cover 33. The reset plate 331 and the ejector rod 32 are connected to each other. A reset spring 332 is sleeved on the ejector rod 32. One end of the reset spring 332 is clamped at the bottom of the reset cover 33, and the other end of the reset spring 332 is clamped on the reset plate 331.

[0050] As Figures 1 to 8 shown, further, the top of the lead screw shaft 4 is rotatably connected to the base plate 1. A lead screw slider 42 is meshingly installed on the lead screw shaft 4. A synchronizing frame 43 is installed on the side wall of the lead screw slider 42. A lifting platform 431 is installed at the end of the synchronizing frame 43. A tray 432 is lapped on the top of the lifting platform 431. The tray 432 slides on the inner walls of two pairs of guide frames 11. A slide plate 421 is installed on the side wall of the lead screw slider 42. A limiting rod 422 is movably penetrated through the slide plate 421. The bottom of the limiting rod 422 is welded to the base plate 1. The limiting rod 422 is parallel to the lead screw shaft 4. A limiting plate 423 is installed at the top of the limiting rod 422. The diameter of the limiting plate 423 is larger than the diameter of the limiting rod 422. The meshing drive between the lead screw shaft 4 and the lead screw slider 42 can accurately control the lifting height of the tray 432. As the plywood is continuously stacked on the tray 432, the tray 432 can stably descend under the drive of the lead screw shaft 4, always maintaining a suitable height, facilitating the subsequent stacking operation of the plywood. The cooperation between the slide plate 421 and the limiting rod 422 provides stable guidance for the movement of the lead screw slider 42, preventing the lead screw slider 42 from rotating or deviating during the movement, ensuring that the tray 432 can lift and lower vertically. The setting of the limiting plate 423 avoids the lead screw slider 42 from detaching from the lead screw shaft 4 due to excessive movement, ensuring the safety and stability of the device operation.

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

[0052] After production, the plywood can be placed on the surface of the pushing plate 24. Then, the operator can start the driving motor 21. When the driving motor 21 operates, the transmission shaft 211 rotates, and then the adjusting roller 2 starts to rotate. As the adjusting roller 2 rotates (based on Figure 8 Figure 8 , the adjusting roller 2 rotates counterclockwise), at this time, 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. At this time, the sliding rod 234 at the bottom of the pushing block 23 slides in the feeding groove 221. Therefore, 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 guiding rod 232 at this time. The guiding rod 232 plays a guiding role. At the same time, the compression spring 233 is compressed synchronously at this time. The compression spring 233 facilitates the later reset operation.

[0054] When the pushing block 23 slides, the pushing plate 24 is driven to slide at this time through the synchronous support 246 and the fixing plate 241. Then, the pushing plate 24 can drive the plywood on its surface to move. The plywood first moves from the top of a pair of guiding frames 11 with a lower height. The guiding plate 111 installed at the top of the guiding frame 11 is in an inclined state, which can guide the moving direction of the plywood to ensure that the plywood remains stable during the movement and does not tilt or shift. As the pushing plate 24 continues to move, the plywood can finally be completely moved above the two pairs of guiding 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 ejector rod 32 slides in the notch 31 of the turntable 3. When the plywood completely moves between the two pairs of guide frames 11, as the turntable 3 rotates, the ejector rod 32 will separate from the notch 31. At this time, the mounting bracket 321 and the ejector rod 32 start to move downward. The slider 323 mounted on the top of the ejector rod 32 can only move along the vertical direction under the restriction of the synchronizing rod 324, ensuring the stable downward movement of the ejector rod 32. Since the top of the ejector rod 32 is slidably connected to the bottom of the pushing plate 24, the downward movement of the ejector rod 32 drives the pushing plate 24 to quickly descend. Then, the plywood on the top of the pushing plate 24 can slide between the two pairs of guide frames 11 at this time. Therefore, the plywood cannot slide horizontally at this time. So when the adjusting roller rotates continuously later and drives the pushing plate 24 to reset horizontally, the plywood on the pushing plate 24 is clamped between a pair of guide frames 11 at this time and will not reset, thus achieving the purpose of discharging. And the discharged plywood can fall onto the tray. When the pushing plate 24 returns to the initial position, the notch 31 on the turntable 3 can just correspond to the ejector rod 32 and the mounting bracket 321. At this time, the return spring 332 quickly rebounds, pushing the return plate 331 and the ejector rod 32 to reset upward, and then driving the pushing plate 24 to return to the initial height, preparing to receive the next piece of plywood.

[0056] During the continuous rotation of the adjusting roller 2, the driving bevel gear 411 can rotate synchronously. When the feeding groove 221 drives the pushing block 23 and the pushing plate 24 to slide, the teeth of the driven bevel gear 41 start to mesh with the driving bevel gear 411. Since the driven bevel gear 41 is a semi-gear and its teeth are adapted to the position of the feeding groove 221, during the meshing process, the lead screw shaft 4 starts to rotate. The top of the lead screw shaft 4 is installed on the base plate 1 by means of a rotational connection to ensure the stable rotation of the lead screw shaft 4. The rotation of the lead screw shaft 4 drives the lead screw sleeve 42 engaged with it to move downward along the axial direction of the lead screw shaft 4. The synchronizing frame 43 mounted on the side wall of the lead screw sleeve 42 will move downward synchronously with the movement of the lead screw sleeve 42. The lifting platform 431 mounted at the end of the synchronizing frame 43 drives the tray 432 to descend. As the number of plywood on the tray 432 continuously increases, the tray 432 continues to descend under the drive of the lead screw shaft 4, always maintaining an appropriate height for the convenient stacking of subsequent plywood.
