Description

Technical Field

[0001] This invention relates to the field of surface treatment of irregularly shaped bamboo and wood, and in particular to an integrated processing device for polishing and coating the surface of irregularly shaped bamboo and wood. Background Technology

[0002] Bamboo and wood materials, with their natural texture and environmentally friendly, renewable characteristics, are widely used in furniture manufacturing, handicrafts processing, decoration, and other fields. Among them, irregularly shaped bamboo and wood products, due to their unique aesthetic appeal, better meet the market's demand for personalized products, and their processing techniques have also received high attention within the industry.

[0003] Surface polishing and protective coating are key processes in the processing of irregularly shaped bamboo and wood products. The quality of polishing directly determines the smoothness and aesthetics of the bamboo and wood product surface, while the protective coating effectively improves the moisture resistance, insect resistance, and wear resistance of the bamboo and wood products, extending their service life. Currently, the industry typically uses a segmented processing technique when processing irregularly shaped bamboo and wood surfaces, that is, polishing is completed first, and then a protective coating is applied separately.

[0004] In the polishing process, existing technologies mostly employ a conveyor belt system combined with fixed polishing blocks. Specifically, irregularly shaped bamboo or wood is placed directly on the conveyor belt and continuously fed into the polishing machine. The machine contains pre-set top and bottom polishing blocks, which are used to polish the surface of the bamboo or wood by rotating or moving. However, this method has significant technical drawbacks: the irregular shape and varied curvature of the bamboo or wood mean that when placed directly on the conveyor belt, there is a lack of targeted fixing and limiting components. Under the combined forces of the conveyor belt and the polishing blocks, the bamboo or wood is prone to positional shifts, shaking, or even flipping. This shift leads to uneven contact between the polishing blocks and the surface of the bamboo or wood, and deviations from the preset polishing path. Consequently, the polishing precision is insufficient, resulting in problems such as over-polishing in some areas, under-polishing in others, and poor surface flatness, severely affecting the polishing quality. Subsequent additional polishing is required, increasing processing costs and time.

[0005] Meanwhile, in the existing processing mode, the polishing process and the protective coating application process are independent of each other, making it impossible to achieve integrated continuous processing. After the polishing operation is completed, the irregularly shaped bamboo and wood need to be manually removed from the conveyor belt and transferred to the coating machine for the application and curing of the protective coating. This segmented process not only increases the cost of manual transfer and reduces the overall processing efficiency, but also makes the polished bamboo and wood surface prone to dust and impurities or damage from bumps during the transfer process, affecting the uniformity and adhesion of the subsequent coating application, resulting in a decrease in the protective effect of the protective coating and further affecting the final quality of the irregularly shaped bamboo and wood products.

[0006] Furthermore, existing fixed sanding blocks struggle to achieve comprehensive sanding of all curved surfaces and edges of irregularly shaped bamboo and wood, often resulting in sanding dead spots. In segmented processing, the parameters for polishing and coating processes cannot be coordinated, making it difficult to guarantee consistent processing. As market demands for higher quality and processing efficiency of irregularly shaped bamboo and wood products continue to rise, existing processing equipment and processes can no longer meet industry needs. Developing an integrated processing device capable of precise positioning and polishing of irregularly shaped bamboo and wood, while also incorporating protective coating functions, has become a pressing technical challenge in the bamboo and wood processing industry.

Detailed Implementation

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0033] An integrated processing device for polishing and applying protective coating to irregularly shaped bamboo and wood surfaces, such as Figures 1-3 As shown, the device includes a base 1 and a rotating block 3. A first motor 2 is located on the front left side of the base 1. A rotating block 3 is fixedly connected to the top of the output shaft of the first motor 2. Two grinding blocks 4 are fixedly connected to the front side of the rotating block 3. Two sponge rods 5 are rotatably connected to the rear side of the rotating block 3. A second motor 6 is located in the middle of the base 1. A rotating component 7 is fixedly connected to the top of the output shaft of the second motor 6. Sliding grooves 8 are provided on the four sides (front, back, left, and right) of the upper part of the rotating component 7. Clamping blocks 9 are slidably connected to each sliding groove 8. A turntable 10 is rotatably connected to the upper part of the rotating component 7, and the turntable 10 is located below the sliding grooves 8. The turntable 10 has inclined grooves 11 on all four sides, front, back, left, and right. The inclined grooves 11 and the lower part of the clamping block 9 are slidably engaged. The rotating component 7 is provided with a drive assembly for driving the clamping block 9 to move. The drive assembly includes a first pulley 12, which is rotatably connected to the lower part of the turntable 10. A third motor 15 is provided at the upper front part of the rotating component 7. The bottom of the output shaft of the third motor 15 is connected to a second pulley 13. A first conveyor belt 14 is connected between the second pulley 13 and the first pulley 12. A torsion spring 16 is connected between the top of the first pulley 12 and the bottom of the turntable 10.

[0034] When using this integrated processing device for polishing and protective coating of irregularly shaped bamboo and wood surfaces, the irregularly shaped bamboo and wood are first placed between the outer sides of the clamping blocks 9. Then, the third motor 15 is turned on. The output shaft of the third motor 15 rotates, driving the torsion spring 16 to rotate via the second pulley 13, the first conveyor belt 14, and the first pulley 12. The rotation of the torsion spring 16 drives the turntable 10 to rotate, which in turn drives the inclined groove 11 to rotate. The rotation of the inclined groove 11 causes the clamping blocks 9 to move outward, clamping the irregularly shaped bamboo and wood in the middle. Subsequently, the first... Motor 2 controls the rotation of rotating block 3, which in turn drives the rotation of polishing block 4. When the two polishing blocks 4 reach the top and bottom positions of the irregularly shaped bamboo / wood, the second motor 6 is activated. The output shaft of the second motor 6 rotates, driving rotating component 7 to rotate. Rotating component 7 then drives all its components to rotate, simultaneously rotating the irregularly shaped bamboo / wood. As the bamboo / wood rotates, the polishing blocks 4 automatically polish it. During polishing, this device can be connected to an external water washing system, allowing water to be automatically sprayed onto the surface of the bamboo / wood. It can achieve a cooling effect and also wash irregularly shaped bamboo and wood. After polishing, the water flow is stopped, and the irregularly shaped bamboo and wood are allowed to dry. Then, the first motor 2 drives the rotating block 3 to rotate, causing the sponge rod 5 to rotate to the top and bottom surfaces of the irregularly shaped bamboo and wood. The sponge rod 5 is coated with paint, and as the irregularly shaped bamboo and wood rotate, the sponge rod 5 can evenly apply the coating to the surface of the irregularly shaped bamboo and wood to achieve a coating effect. After the coating is completed, the second motor 6 is turned off, and the first motor 2 controls the rotating block 3, polishing block 4, and sponge rod 5 to rotate and reset. Then, the third motor is controlled to... The output shaft of machine 15 reverses, driving turntable 10 to reverse through first pulley 12, second pulley 13, first conveyor belt 14, and torsion spring 16. Turntable 10 drives clamping block 9 to move inward through inclined groove 11 to reset and release the irregularly shaped bamboo and wood, allowing people to remove the irregularly shaped bamboo and wood. In summary, this device can not only clamp irregularly shaped bamboo and wood, thus restricting their position and preventing positional displacement, shaking, or even flipping during polishing, thereby improving polishing accuracy, but also enables the direct application of a protective coating after polishing, improving efficiency.

[0035] like Figures 2-3 As shown, it also includes a support plate 17, which is slidably connected to the upper part of the rotating part 7. The bottom front and rear sides of the support plate 17 and the rotating part 7 are connected to the first spring 21. The rotating part 7 is rotatably connected to the threaded rod 18. The lower part of the support plate 17 and the threaded rod 18 are threadedly connected. The lower part of the first pulley 12 is fixedly connected to the first block 19. The upper part of the threaded rod 18 is provided with the second block 20. The first block 19 and the second block 20 are pressed together.

[0036] During the process of clamping the inner side of the irregularly shaped bamboo and wood by moving the clamping block 9, people need to hold the irregularly shaped bamboo and wood with their hands the whole time, which is very strenuous. For this reason, this embodiment is provided with a support plate 17. People can place the irregularly shaped bamboo and wood flat on the top of the support plate 17. After the clamping block 9 clamps the inner side of the irregularly shaped bamboo and wood, since the support plate 17 supports the bottom of the irregularly shaped bamboo and wood, it is impossible to polish the bottom surface of the irregularly shaped bamboo and wood. Therefore, the support plate 17 needs to be removed after the irregularly shaped bamboo and wood is clamped. Therefore, the third motor 15 controls the first pulley 12 and the turntable 10 to rotate. The first pulley 12 also drives the first block 19 to rotate. When the turntable 10 rotates to its limit and the clamping block 9 has completely clamped the irregularly shaped bamboo and wood, the clamping block 9 can no longer move, and the turntable 10 can no longer rotate. At this time, the first block 19 and the second block 20 are just pressed together. The first pulley 12 continues to rotate, the torsion spring 16 is twisted, the first pulley 12 continues to drive the first block 19 to rotate, so that the first block 19 drives the second block 20 to rotate, the second block 20 rotates, and the threaded rod 18 rotates, the threaded rod 18 rotates and drives the support plate 17 to descend, the first spring 21 is compressed, the support plate 17 descends and can separate the irregular bamboo and wood, so as to facilitate subsequent polishing and coating work. After the polishing and coating work is completed, the third motor 15 controls the first pulley 12 to reverse, the first pulley 12 reverses and drives the first block 19 to reverse. After the first block 19 and the second block 20 are separated, the first spring 21 drives the support plate 17 to rise again to support the irregular bamboo and wood. After the clamping block 9 moves inward to release the irregular bamboo and wood, the irregular bamboo and wood will not fall directly onto the base 1.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a support frame 22. The symmetrically arranged support frames 22 are fixedly connected to the top of the base 1. The upper and lower sides of the support frame 22 are rotatably connected to the third pulleys 23. The third pulleys 23 and the support frame 22 are connected by a damping mechanism. Under the action of the damping mechanism, the third pulleys 23 can remain stationary without external forced drive. The third pulleys 23 on the same longitudinal side are wound with a second conveyor belt 24. The second conveyor belt 24 is fixedly connected to the outside of the second conveyor belt 24 with equally spaced guide blocks 25. The guide blocks 25 are rotatably connected to the rotating plates 26. The rotating plates 26 and the guide blocks 25 are connected to torsion springs 261. The guide blocks 25 are slidably connected to the abutments 27. The abutments 27 and the rotating plates 26 are pressed together. The abutments 27 and the second conveyor belt 24 are slidably connected. The abutments 27 and the second conveyor belt 24 are connected to the abutments 27 and the second conveyor belt 24. The second springs 28 are wound around the abutments 27.

[0038] like Figure 4As shown, it also includes a guide plate 29, which is fixedly connected inside the support frame 22. The guide plate 29 is located inside the second conveyor belt 24. The guide plate 29 and the abutment 27 are pressed together. The lower inner side of the guide plate 29 has a groove 30.

[0039] like Figure 1 and Figure 4 As shown, it also includes a one-way gear 31. The third pulley 23 below is fixedly connected to the one-way gear 31 on both the front and rear sides. The base 1 is slidably connected to the rack 32 on both the left and right sides. The rack 32 and the one-way gear 31 mesh.

[0040] As mentioned earlier, each time irregularly shaped bamboo or wood is polished, it needs to be placed manually, which is very troublesome. Therefore, this embodiment proposes an automatic feeding solution, as follows:

[0041] The irregularly shaped bamboo or wood can be placed between the rotating plates 26. A power-driven rack 32 rises, which in turn drives a one-way gear 31 to rotate. The rotation of the one-way gear 31 drives a third pulley 23 and a second conveyor belt 24 to rotate. The second conveyor belt 24 drives a guide block 25 and the rotating plates 26 to rotate. When the abutment 27 contacts the groove 30, the second spring 28 causes the adjacent abutment 27 to move outward. After the abutment 27 separates from the rotating plates 26, the irregularly shaped bamboo or wood will automatically fall due to gravity. The wood is pressed downward by the rotating plate 26, the torsion spring 261 is twisted, and the irregular bamboo and wood automatically fall onto the support plate 17. After the irregular bamboo and wood separate from the rotating plate 26, the torsion spring drives the rotating plate 26 to rotate and reset. When the abutment 27 moves away from the groove 30, the abutment 27 is moved inward, the second spring 28 is compressed, and the abutment 27 abuts against the bottom of the rotating plate 26 again. When the power source drives the rack 32 to descend, the descent of the rack 32 will drive the one-way gear 31 to rotate freely. At this time, the third pulley 23 and the second conveyor belt 24 will not reverse.

[0042] like Figures 6-8 As shown, it also includes a cylinder 34, which is symmetrically arranged and fixedly connected to the bottom of the support plate 17. A one-way air inlet is provided at the bottom of the cylinder 34. Hollow piston rods 35 are slidably connected inside the cylinder 34. A buffer plate 33 is connected between the top of the hollow piston rods 35. A plug 36 is slidably connected to the upper part of the hollow piston rods 35. The plug 36 blocks the hole above the hollow piston rods 35. A third spring 37 is connected between the plug 36 and the hollow piston rods 35.

[0043] like Figure 6As shown, it also includes cylinders 38. The symmetrically arranged cylinders 38 are fixedly connected to the top of the base 1. A lifting frame 39 is slidably connected between the top of the telescopic rod of the cylinder 38. A fourth spring 40 is connected between the bottom left and right sides of the lifting frame 39 and the telescopic rod of the cylinder 38. The telescopic rod of the cylinder 38 is fixedly connected to the rack 32.

[0044] like Figure 9 As shown, it also includes guide plates 41. The guide plates 41 are symmetrically arranged and fixedly connected to the front and rear sides of the top of the base 1. The upper part of the guide plates 41 is provided with parallelogram grooves 42. The lifting frame 39 is slidably connected to the front and rear sides with lifting plates 43. The bottom of the lifting plates 43 and the buffer plates 33 are pressed together, and the lifting plates 43 and the parallelogram grooves 42 are pressed together.

[0045] When irregularly shaped bamboo or wood falls onto the top of the support plate 17, it is prone to collision. Therefore, this embodiment is equipped with a cushioning mechanism, as follows:

[0046] When the irregularly shaped bamboo falls, it will land on top of the buffer plate 33. The irregularly shaped bamboo will first contact the plug 36, and the plug 36 will descend and open the hole. The third spring 37 will be compressed. At this time, the gas in the cylinder 34 will be discharged through the hole. At this time, the irregularly shaped bamboo will slowly drive the hollow piston rod 35 to descend due to gravity, and the gas will slowly degas. By slowly degassing, the irregularly shaped bamboo can slowly fall to the top of the support plate 17, which can achieve the purpose of buffering and avoid collision between the irregularly shaped bamboo and the support plate 17. After the irregularly shaped bamboo is polished and coated, and after the irregularly shaped bamboo is removed, the irregularly shaped bamboo and the plug 36 are separated. Under the action of the third spring 37, the plug 36 is driven to move upward and reset to re-block the hole.

[0047] When processing the next irregularly shaped bamboo or wood, the position of the buffer plate 33 needs to be restored. Therefore, the extension rod of the control cylinder 38 extends, simultaneously driving the rack 32 and the lifting frame 39 to rise. The rise of the lifting frame 39 drives the lifting plate 43 to rise. The top of the lifting plate 43 contacts the buffer plate 33 and pushes it to rise. The rise of the buffer plate 33 drives the hollow piston rod 35 to move upward. When the hollow piston rod 35 moves upward, under the action of the one-way air inlet, the gas will automatically enter the cylinder 34. When the lifting plate 43 rises along the inner groove of the parallelogram groove 42, it can push the buffer plate 33 to rise. When the lifting plate 43 moves up to the parallelogram groove... When the upper inclined groove 11 of 42 is reached, the lifting plate 43 will automatically move outward and separate from the buffer plate 33. In this way, the buffer plate 33 remains stationary. Then, the telescopic rod of the cylinder 38 continues to extend, while the lifting frame 39 stops moving. At this time, the fourth spring 40 is compressed, so the rack 32 rises and drives the one-way gear 31 to rotate, causing the next irregular bamboo or wood to fall down. Then, the telescopic rod of the control cylinder 38 retracts, which will drive the rack 32 to descend and reset. At the same time, the fourth spring 40 returns to its original position, and the lifting frame 39 and its components descend and reset. When the lifting plate 43 descends along the outer slot to the lower inclined groove 11, the lifting plate 43 will automatically move inward and reset.

[0048] like Figure 10 As shown, it also includes a storage tank 44, which is fixedly connected to the top left front side of the base 1. The top of the storage tank 44 is provided with an inlet pipe, and the bottom of the inlet pipe is connected to a perforated pipe 45 through a connecting pipe. The perforated pipe 45 is located inside the rotating block 3, and the perforated pipe 45 and the rotating block 3 are rotatably connected.

[0049] In order to add coating pigment to the sponge rod 5 in a timely manner, the feed pipe is connected to the external feeding device, so that the coating pigment is injected into the storage tank 44 through the feed pipe and enters the perforated pipe 45. When the rotating block 3 rotates and drives the sponge rod 5 to rotate to the surface of the irregular bamboo and wood, the sponge rod 5 is aligned with the hole of the perforated pipe 45, and the pigment will enter and permeate into the sponge rod 5 through the hole for filling. When the rotating block 3 reverses and drives the sponge rod 5 to rotate away from the surface of the irregular bamboo and wood, the sponge rod 5 and the hole of the perforated pipe 45 are misaligned, and the filling stops.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
