Description

Technical Field

[0001] The invention relates to the technical field of grinding and polishing, in particular to a grinding and polishing machine for manufacturing wooden products. Background Art

[0002] When manufacturing wood products, in order to remove burrs and uneven defects on the surface of the wood products, it is usually necessary to grind and polish the wood products to improve the surface quality of the wood products and improve the subsequent coating quality of the wood products.

[0003] The surface shapes of wooden products are varied. When grinding and polishing unconventional shaped wooden products, in order to ensure the grinding and polishing effect of the wooden products and avoid grinding dead angles, the polishing wheel needs to always fit the surface of the wooden products. During this process, the staff needs to adjust the position of the wooden products many times, which increases the complexity of the operation. In addition, during manual adjustment, each position adjustment will introduce new errors due to the staff's operation, resulting in uneven grinding and polishing, thereby affecting the final quality of the wooden products.

[0004] When grinding and polishing wood products, a large amount of heat will be generated and the surface of the wood products will be damaged due to the high-speed rotation of the polishing wheel and its friction with the surface of the wood products. Therefore, the wood products need to be pretreated before grinding and polishing. In the process of traditional wood product grinding and polishing, the pretreatment agent is manually applied to the surface of the wood products, which not only increases the labor intensity of the staff, but also reduces the work efficiency. At the same time, due to the limitation of the surface shape of the wood products, dead angles will appear in the application, which will affect the protective effect of the pretreatment agent on the wood products, and then affect the effect of grinding and polishing.

[0005] For this reason, a grinding and polishing machine for manufacturing wood products is proposed. Summary of the invention

[0037] The above implementation works as follows:

[0038] The initialization steps are as follows:

[0039] The staff puts the pretreatment agent into the sprayer 321 . In the initial state, the sliding bracket 32 ​​is located on the top of the workbench body 1 and away from the top bracket 21 .

[0040] The working steps are as follows:

[0041] The following is an explanation of the process of spraying the pretreatment agent onto the surface of the wood product by the spraying component:

[0042] like Figures 4 to 8 As shown, the staff places the wooden product that needs to be ground and polished on the top of the placement plate 35, and then the electric telescopic rod 34 is powered on and starts to extend downward, and the rotating seat at the bottom of the electric telescopic rod 34 conflicts with the wooden product, so that the wooden product can be fixed under the mutual cooperation of the rotating seat and the placement plate 35. After the wooden product is fixed, the external drive device of the placement plate 35 is started to drive the placement plate 35 to start rotating. At the same time, the staff holds the handle 33 and pushes the sliding bracket 32 ​​toward the top bracket 21. The sliding bracket 32 ​​slides along the fixed track 31 toward the top bracket 21. The sliding of the sliding bracket 32 ​​drives the gear rod 317 fixedly connected to it to move synchronously. Because the linkage gear 320 is located on the moving path of the gear rod 317, when the gear rod When gear rod 317 moves to mesh with linkage gear 320, the movement of gear rod 317 drives linkage gear 320 to rotate, and the rotation of linkage gear 320 drives the connecting rotating rod 318 fixedly connected thereto to rotate synchronously, and the rotation of connecting rotating rod 318 drives the control slot rod 319 fixedly connected thereto to rotate synchronously, and the rotation of control slot rod 319 causes the end of control switch 322 away from sprayer 321 to slide in its arc groove, and when control switch 322 slides to conflict with the inner wall of control slot rod 319, the rotation of control slot rod 319 causes its inner wall to push control switch 322 to rotate inside sprayer 321, and at this time sprayer 321 is turned on, and pretreatment agent enters the interior of connecting pipe 323 and is sprayed out by nozzle 316.

[0043] At the same time, the rotation of the placement plate 35 drives the active belt shaft bevel gear 37 to rotate inside the fixed support plate 36 through the connecting belt 38 connected to it for transmission. The rotation of the active belt shaft bevel gear 37 drives the driven belt shaft bevel gear 39 meshing with it to rotate inside the sliding bracket 32. The rotation of the driven belt shaft bevel gear 39 drives the linkage rotating rod 310 fixedly connected to it to rotate synchronously. The rotation of the linkage rotating rod 310 drives the sliding rod 311 to rotate around the driven belt shaft bevel gear 39. During the rotation of the sliding rod 311, the sliding rod 311 will rotate around the driven belt shaft bevel gear 39. The surface of the connecting rod 314 slides and pushes the connecting rod 314 to swing back and forth. The up and down reciprocating swing of the connecting rod 314 drives the rotating connecting plate 313 to swing back and forth. The reciprocating swing of the rotating connecting plate 313 drives the spray head 316 to swing back and forth synchronously through the connecting bracket 315. The pretreatment agent can be evenly and comprehensively sprayed on the surface of the wood product through the up and down swing of the spray head 316 and the rotation of the wood product, thereby reducing the influence of the heat and friction generated during grinding and polishing on the wood product, and better protecting the surface of the wood product.

[0044] Since the operation time of the sprayer 321 is the built-in operation time, the sprayer 321 will automatically shut down after running for a period of time, and the nozzle 316 will no longer spray the pretreatment agent outward.

[0045] The following is an explanation of the process of fixing the sliding bracket 32 ​​by the fixing component:

[0046] like Figures 5 to 7 As shown, the sliding of the sliding bracket 32 ​​toward the top bracket 21 drives the clamping rod 47 fixedly connected thereto to move synchronously. When the clamping rod 47 moves to enter the interior of the fixed shell 41, the clamping rod 47 will contact the inclined surface of the clamping block 46 close to the connecting block 43 to make the clamping block 46 rotate around the fixed axis 45, and the clamping rod 47 continues to move toward the top bracket 21 inside the fixed shell 41. The movement of the clamping rod 47 will push the connecting block 43 to slide toward the top bracket 21 and compress the fixing spring 42. When the movement of the clamping rod 47 makes the clamping groove on the clamping rod 47 correspond to the end of the clamping block 46 close to the connecting block 43, the end of the clamping block 46 close to the connecting block 43 enters the interior of the clamping groove. At this time, the clamping block 46 is clamped with the clamping rod 47, and then the position of the sliding bracket 32 ​​can be fixed to prevent the wood product from accidentally moving during the grinding and polishing process. At this time, the surface of the wood product and the polishing wheel 25 are in contact with each other.

[0047] The following is an explanation of the process of grinding and polishing wood products by the polishing component:

[0048] like Figures 1 to 3As shown, the motor 29 is powered on and starts to drive the fixed universal joint 28 to start rotating. The rotation of the fixed universal joint 28 drives the connecting universal joint 27 to rotate synchronously. The rotation of the connecting universal joint 27 drives the starting universal joint 26 to rotate. The rotation of the starting universal joint 26 drives the polishing wheel 25 to rotate synchronously. The rotation of the polishing wheel 25 enables it to grind and polish the side of the wooden product. At the same time, during the grinding and polishing process, the rotation of the placement plate 35 drives the wooden product fixed thereon to rotate synchronously. For special-shaped wooden products, when the side protrusions of the wooden products collide with the polishing wheel 25 during its rotation, the side of the wooden product will The polishing wheel 25 is pushed to move away from the sliding bracket 32. The movement of the polishing wheel 25 drives the connecting slider 23 to slide inside the sliding groove 22 away from the sliding bracket 32 ​​and compress the reset spring 24. The sliding of the connecting slider 23 drives the starting universal joint 26 to rotate inside the connecting universal joint 27. The rotation of the starting universal joint 26 drives the connecting universal joint 27 to rotate inside the fixed universal joint 28. At this time, the rotation of the fixed universal joint 28 will still drive the starting universal joint 26 to rotate through the connecting universal joint 27. The rotation of the starting universal joint 26 drives the polishing wheel 25 to rotate to grind and polish the wooden products.

[0049] When the raised part of the side of the wooden product no longer conflicts with the polishing wheel 25, under the elastic stretching action of the reset spring 24, the polishing wheel 25 slides in the sliding groove 22 toward the sliding bracket 32 ​​until it fits with the side of the wooden product, and then the polishing wheel 25 can synchronously slide in the sliding groove 22 as the surface shape of the wooden product changes, so that the polishing wheel 25 can dynamically change with the surface shape of the wooden product and always fits with the surface of the wooden product. This dynamic adaptability makes the polishing component no longer limited to the fixed shape of the wooden product. Compared with the existing grinding and polishing device for polishing special-shaped wooden products, the polishing wheel 25 cannot fully fit with the surface of the special-shaped wooden product and needs to be manually adjusted for multiple times. During the rotation of the special-shaped wooden product, the polishing wheel 25 can perform fully fitting and adaptive grinding and polishing on the special-shaped wooden product, avoiding polishing dead angles, thereby improving the adaptability and flexibility of the polishing component.

[0050] The following is a description of the process of releasing the sliding bracket 32:

[0051] like Figures 4 to 8As shown, when the grinding and polishing of the wood product is completed, the motor 29 is powered off, the polishing wheel 25 no longer rotates, the external drive device of the placement plate 35 is powered off, and the placement plate 35 no longer rotates. Then the staff presses the clamping block 46 away from one end of the clamping spring 44. At this time, the clamping block 46 close to the end of the clamping spring 44 slides toward the top bracket 21 and compresses the clamping spring 44. At the same time, the clamping block 46 rotates around the fixed shaft 45 as the axis, and the end of the clamping block 46 located inside the clamping groove on the clamping rod 47 rotates to leave the inside of the clamping groove. At this time, the clamping block 46 is no longer clamped with the clamping rod 47. Under the elastic extension action of the fixed spring 42, the connecting block 43 will push the clamping rod 47 to slide away from the top bracket 21. The staff can hold the handle 33 to pull the sliding bracket 32 ​​to move away from the top bracket 21. The clamping rod 47 leaves the inside of the fixed shell 41, and the clamping block 46 slides and resets under the elastic extension action of the clamping spring 44.

[0052] When the sliding bracket 32 ​​moves away from the top bracket 21, the movement of the sliding bracket 32 ​​drives the gear rod 317 to move synchronously. When the gear rod 317 and the linkage gear 320 are meshed with each other, the movement of the gear rod 317 will drive the linkage gear 320 to rotate in the opposite direction. The opposite rotation of the linkage gear 320 drives the connecting rotating rod 318 fixedly connected thereto to rotate in the opposite direction. The opposite rotation of the connecting rotating rod 318 drives the control slot rod 319 to rotate in the opposite direction. When the control slot rod 319 rotates, the end of the control switch 322 away from the sprayer 321 slides in the arc groove of the control slot rod 319. When the control slot rod 319 slides to conflict with the inner wall of the control slot rod 319, the opposite rotation of the control slot rod 319 pushes the control switch 322 to rotate in the opposite direction inside the sprayer 321 and reset.

[0053] When the sliding bracket 32 ​​moves to the initial position, the electric telescopic rod 34 is energized to retract upward and no longer fix the wooden product. At this time, the staff can remove the ground and polished wooden product to proceed to the next step.
