Description

Technical Field

[0001] This utility model relates to the field of wood-plastic composite processing technology, and in particular to a surface smoothing device for wood-plastic composite processing. Background Technology

[0002] Wood-plastic composites (WPC) are a new type of environmentally friendly material, mainly composed of wood fibers (or wood chips) and plastics (such as polyethylene and polypropylene), possessing excellent physical and chemical properties. WPC is not easily affected by moisture or insects, making it suitable for outdoor environments. However, after molding, WPC products often have defects such as burrs, unevenness, and scratches on their surface. These surface defects not only affect the appearance but may also affect subsequent coating and bonding processes. Therefore, surface treatment is particularly important.

[0003] For example, Chinese patent CN210968150U discloses a surface smoothing device for processing wood-plastic composite products, including a shock-absorbing sleeve, a base, a limiting plate, and a frame. The base has shock-absorbing sleeves fixed at each of its four corners, and a groove at its top. A first rotating rod is located at one end of the groove, and a second rotating rod is located at the other end. The second rotating rod is connected to the first rotating rod via a pulley mechanism. A third motor is fixed to one end of the groove, and its output is connected to the second rotating rod. A second motor is fixed to one end of the frame, and its output is connected to a threaded screw via a pulley mechanism. This invention, by installing a base, frame, electric slide rail, sliding sleeve, threaded screw, drive block, hydraulic telescopic rod, first motor, polishing disc, and second motor, facilitates continuous polishing of wood-plastic composite boards. It has a high degree of intelligence, is easy to operate, and saves time and effort.

[0004] However, although the aforementioned patent can achieve surface smoothing of wood-plastic composite products, its device can only smooth one side of the wood-plastic composite product and cannot smooth the other side. If the other side needs to be processed, the processed part needs to be manually disassembled and then flipped over, which is time-consuming and labor-intensive. In addition, the waste generated during the sanding process is easy to fly everywhere. If it is not handled in time, it may endanger the health of the workers and also affect the operation of the machine, creating potential hazards to equipment safety and physical health.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-5This utility model provides a surface smoothing device for processing wood-plastic composite products: It includes a support frame 1, with two rotating shafts 2 rotatably connected to the inner wall of the support frame 1. Each rotating shaft 2 has a clamping plate 3 fixedly connected to its opposite end. A clamping assembly is provided on the clamping plate 3, consisting of a clamping screw 4 and a rubber pad 5, with the screw 4 and pad 5 respectively mounted on the clamping plate 3. A flipping assembly is provided on the rotating shafts 2. A threaded rod 6 is rotatably connected to the inner wall of the support frame 1, and a threaded block 7 is fitted onto the outer wall of the threaded rod 6. A groove 8 is formed at the bottom of the threaded block 7, and a servo motor 9 is fixedly installed within the groove 8. The output end of the servo motor 9 is fixedly connected to a threaded rod 10. A threaded block 11 is fitted on the outer wall of the threaded rod 10. A grinding component is provided at the bottom of the threaded block 11. A dust collection component is provided on the outer wall of the support frame 1. Through the coordinated use of the grinding disc 18, dust collection hole 19, outer shell 20 and dust collection component, the grinding debris can be absorbed during the leveling process, thereby reducing dust pollution, protecting respiratory health, maintaining a clean working environment, avoiding machine malfunctions due to flying debris, extending machine life, and helping to maintain the normal operation and performance of the equipment.

[0031] The flipping assembly includes a cylinder 12 fixedly installed on the upper part of the inner wall of the support frame 1. A push block 13 is fixedly connected to the telescopic end of the cylinder 12. A rack 14 is fixedly connected to one side of the push block 13. A gear 15 is meshed with the bottom of the rack 14. The gear 15 is fixedly connected to the outer wall of one of the rotating shafts 2. The grinding assembly includes a cylinder 16 fixedly installed at the bottom of the threaded block 11. A drive motor 17 is fixedly connected to the telescopic end of the cylinder 16. A grinding disc 18 is fixedly connected to the output end of the drive motor 17. A dust suction hole 19 is opened at the bottom of the grinding disc 18. A housing 20 is fixedly connected to the bottom of the drive motor 17. The housing 20 is rotatably connected to the grinding disc 18.

[0032] The vacuuming assembly includes a collection box 21 fixedly mounted on the outer wall of a support frame 1. A collection tray 22 is slidably connected inside the collection box 21. A second drive motor 23 is fixedly connected to the top of the collection box 21. An exhaust fan 24 is fixedly connected to the output end of the second drive motor 23. An exhaust shell 25 is fixedly connected to the outer wall of the second drive motor 23. A filter screen 26 is fixedly connected to the inner wall of the exhaust shell 25. Multiple exhaust holes 27 are provided on the outer wall of the exhaust shell 25. A vacuum hose 28 is fixedly connected to one side of the outer wall of the exhaust shell 25. 28 is fixedly connected to the outer shell 20. A fixing buckle 29 is snapped into the center of the outer wall of the vacuum hose 28. By setting the vacuum hose 28, the device can work normally during the movement of the device. The fixing buckle 29 can prevent the vacuum hose 28 from falling off due to being too long and affecting the polishing, thus avoiding safety hazards. A guide rod 30 is slidably connected to the outer wall of one end of the threaded block 7. A drive motor 31 is fixedly connected to one end of the threaded rod 6. The threaded rod 20 is rotatably connected to the inner wall of the threaded block 21.

[0033] Working principle: First, place the wood-plastic product to be flattened between two clamping plates 3. Then, by turning the clamping screw 4, the wood-plastic product is clamped. Then, the drive motor 31 is started, and the output end drives the threaded rod 6 to rotate, so that the threaded block 7 moves along the guide rod 30, thereby enabling the device to move laterally. Then, the servo motor 9 in the groove 8 at the bottom of the threaded block 7 is started, and the output end drives the threaded rod 10 to rotate, so that the threaded block 11 moves, thereby enabling the device to move vertically. Then, the cylinder 16 at the bottom of the threaded block 11 is started, so that the telescopic end extends and retracts, driving the drive motor at the bottom to move up and down. Then, the rotation of the output end of the servo motor 9 causes the grinding disc 18 to rotate, thereby enabling flexible control of the device, allowing the user to flexibly control the grinding position and make the surface flatter.

[0034] Then, during the smoothing process, the drive motor 23 can be started, and the output end drives the suction fan 24 to rotate, so that the grinding debris enters the outer casing 20 through the dust suction hole 19. Then, under the action of the suction airflow, it enters the dust suction hose 28. Then, under the blocking action of the filter screen 26, the debris enters the collection box 21 at the bottom. By pulling out the collection box 22, the debris generated by the device can be easily cleaned up, thus enabling more comprehensive cleaning of the debris generated during the smoothing process, avoiding debris splashing during the smoothing process, improving equipment safety, and protecting the health of the staff.

[0035] After one side is leveled, the cylinder 12 is activated, and the telescopic end drives the push block 13 to move, thereby causing the rack 14 to move synchronously. The rack 14 meshes with the gear 15, causing the gear 15 to rotate, which in turn drives the two rotating shafts 2 to rotate. After completing a 180-degree rotation, the wood-plastic product can be flipped over, thus avoiding manual flipping by workers, reducing labor intensity, speeding up production, improving work efficiency, and also improving safety in the production process and reducing the risk of work-related injuries.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
