Description

Technical Field

[0001] This invention relates to the field of composite flooring processing technology, specifically a surface treatment machine for composite flooring production and processing. Background Technology

[0002] Composite flooring, also known as three-layer laminated wood flooring, three-layer dust-free wood flooring, or pre-finished painted three-layer wood flooring, is a new type of decorative material. It is mainly used for interior flooring and wall decoration in buildings, vehicles, and ships. Relying on standardized production, it achieves efficient resource utilization and environmental safety control, ultimately making composite flooring a modern flooring material that combines aesthetics, durability, economy, and convenient installation.

[0003] Composite flooring processing refers to the process of processing raw materials through a series of processes to finally produce composite flooring products that can be used for indoor floor decoration. This process not only gives the flooring a beautiful decorative effect, but also significantly improves its physical properties and service life. The smoothness of its surface, the flatness and smoothness of its edges are key indicators that determine the quality and appearance of the product. In order to polish the burrs on the composite flooring, surface treatment machines are required.

[0004] In actual use, traditional polishing methods usually rely on multiple independent polishing stations or manual adjustment of the composite flooring position. For example, operators need to first send the composite flooring into a double-sided polishing machine for processing, then take it out and reposition the composite flooring to polish the edges. This multi-process polishing method requires frequent manual intervention and material turnover, which affects the working efficiency of the surface treatment machine. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-11 As shown, the present invention is a composite flooring production and processing surface treatment machine, including a machine body 1, a first driving device 2 and a second driving device 4 fixedly connected to the upper side of the machine body 1 respectively, an edge grinding mechanism is provided above the machine body 1, a U-shaped frame 5 is provided above the first driving device 2, two first rotating shafts 6 are rotatably connected to the inner side of the U-shaped frame 5, and a U-shaped plate 7 is fixedly connected between the two first rotating shafts 6. Two support plates 8 are fixedly connected to both ends of the U-shaped plate 7. A round rod 9 is fixedly connected between the two sets of support plates 8. Two first polishing blocks 10 are slidably connected to the outer surfaces of the two round rods 9. Two first springs 11 are fixedly connected between the two first polishing blocks 10. Two second polishing blocks 31 are provided on one side of the second driving device 4.

The clamping and positioning mechanism is used to fix the composite floor. A side plate 12 is fixedly connected to one side of the U-shaped frame 5, and an arc block 13 is fixedly connected to one side of the side plate 12. The arc block 13 is used to drive the clamping and positioning mechanism to move upward.

[0025] A first L-shaped plate 21 is fixedly connected to the upper side of the U-shaped plate 7. A first electric push rod 22 is fixedly connected to one side of the first L-shaped plate 21. A lifting frame 23 is fixedly connected to the output end of the first electric push rod 22. A connecting plate 24 is fixedly connected to the lower side of the lifting frame 23. The connecting plate 24 is used to drive the composite floor to move. A horizontal plate 56 is fixedly connected to one side of the machine body 1. A cam groove 57 is opened on one side of the horizontal plate 56. One side of the first rotating shaft 6 passes through the U-shaped frame 5 and extends to one end of the U-shaped frame 5. A connecting piece 58 is fixedly connected to one side of the first rotating shaft 6. A guide wheel 59 is fixedly connected to one side of the connecting piece 58, and the guide wheel 59 is located inside the cam groove 57. The guide wheel 59 can move within the cam groove 57 through the installation and use of the cam groove 57. When the guide wheel 59 moves towards the upward inclined trajectory, the connecting piece 58 can drive the U-shaped plate 7 to rotate slowly. Subsequently, when the guide wheel 59 enters the horizontal trajectory, the U-shaped plate 7 can complete a 90-degree automatic rotation, saving resources and eliminating the need for an additional motor drive. The first drive device 2 is a screw transmission mechanism, which drives the screw to rotate by the output shaft of the servo motor. A displacement plate is threaded onto the screw, and the displacement plate is fastened to the U-shaped frame 5, thus allowing the U-shaped frame 5 to move and adjust. The first drive device 2 is existing technology and is not limited thereto.

[0026] The first driving device 2 is used to drive the U-shaped frame 5 to move, and the second driving device 4 is used to drive the two second polishing blocks 31 to move synchronously. The two second polishing blocks 31 are used for double-sided polishing of the composite floor. In addition, the second driving device 4 is a bidirectional screw transmission mechanism, which drives the bidirectional threaded screw to rotate by the output shaft of the servo motor. Two displacement plates are symmetrically arranged and threaded on the bidirectional threaded screw. The two second polishing blocks 31 are respectively fastened to the two displacement plates, so that the two second polishing blocks 31 can move towards each other or relative to each other. The second driving device 4 is prior art and is not limited thereto.

[0027] The edge grinding mechanism includes a mounting bracket 3 fixed on the upper side of the machine body 1. A second rotating shaft 33 is rotatably connected to one side of the mounting bracket 3. A gear 34 is fixedly connected to the lower side of the second rotating shaft 33. T-slots 35 are provided at both ends of the mounting bracket 3. Slider 36 is slidably connected inside the two T-slots 35. A rack 37 that meshes with the gear 34 is fixedly connected to the lower side of the two sliders 36. Two L-shaped plates 38 are fixedly connected to the outer sides of each of the two racks 37. A second electric push rod 39 is fixedly connected to one side of each of the two second L-shaped plates 38. A third polishing block 40 for polishing the composite flooring is fixedly connected to the output end of each of the two second electric push rods 39. The two third polishing blocks 40 are symmetrically arranged. Through the arrangement of T-slots 35 and sliders 36, the two sliders 36 can move and adjust within the two T-slots 35. This allows the two racks 37 to move smoothly relative to each other or towards each other, enabling the two third polishing blocks 40 to reliably and stably polish the edges of the composite flooring. The grinding and polishing process yields excellent results. A third servo motor is fixedly connected to the other side of the mounting bracket 3, and the output shaft of the third servo motor is tightly connected to the second rotating shaft 33. The symmetrical reciprocating grinding mechanism driven by the rotatable processing table 14, gear 34, and rack 37 can automatically complete the fine grinding of the four sides of the floor, ensuring that the processing benchmark of each side is consistent, eliminating the positioning error caused by traditional multi-process, and making the edge treatment more uniform and thorough. At the same time, the entire system has a compact structure and smooth process connection, achieving efficient and continuous automated production while ensuring high processing accuracy.

[0028] A top frame 55 is fixedly connected to the upper side of the machine body 1. The top frame 55 is located below the edge grinding mechanism. A third rotating shaft 41 is rotatably connected to the upper side of the top frame 55. A top plate 54 is fixedly connected to the upper side of the third rotating shaft 41. The lower side of the processing table 14 is fastened to the upper side of the top plate 54. A rubber pad 43 is fixedly connected to the upper side of the processing table 14. By setting the rubber pad 43, the rubber pad 43 above the processing table 14 can increase the friction with the composite floor, so that the composite floor can be placed stably, which is convenient for subsequent stable and reliable grinding and polishing. A fourth servo motor is fixedly connected to the bottom of the top frame 55. The output shaft of the fourth servo motor is fastened to the third rotating shaft 41.

[0029] The clamping and positioning machine includes a groove 44 formed on both the processing table 14 and the rubber pad 43. A second slide rod 46 is slidably connected to the bottom of the groove 44. A suction cup 45 is fixedly connected to the upper side of the second slide rod 46. The lower side of the second slide rod 46 passes through the processing table 14 and extends to the lower side of the processing table 14. A conical block 47 is fixedly connected to the lower side of the second slide rod 46. A third spring 48 is fixedly connected between the conical block 47 and the processing table 14. The arc block 13 and the conical block 47 are in contact. When the first drive device 2 drives the U-shaped frame 5 away from the edge grinding and polishing position, the arc block 13 can release the pressure on the conical block 47. Then, the two second electric push rods 39 drive the two third grinding blocks 40 to move relative to each other and away from the composite floor. Then, the composite floor held by the suction cup 45 is removed to complete the polishing work of the composite floor.

[0030] A third L-shaped plate 49 is fixedly connected to one side of the mounting bracket 3. A third slide rod 50 is slidably connected to one side of the third L-shaped plate 49. A pressure block 51 is fixedly connected to one side of the third slide rod 50. An upper inclined block 32 is fixedly connected to the outer surface of the pressure block 51. The other side of the third slide rod 50 passes through the third L-shaped plate 49 and extends to the other side of the third L-shaped plate 49. A second mounting block 52 is fixedly connected to the other side of the third slide rod 50. A fourth spring 53 is fixedly connected between the second mounting block 52 and the third L-shaped plate 49.

[0031] The U-shaped plate 7 is internally connected to a bidirectional threaded rotating rod 15, and internally fixedly connected to a connecting rod 17. Two symmetrically arranged vertical plates 19 are threaded onto the bidirectional threaded rotating rod 15. The connecting rod 17 limits and guides the movement of the two vertical plates 19, ensuring smooth back-and-forth movement to clamp composite flooring of different sizes, thus improving the applicability of the surface treatment machine. The inner sides of both vertical plates 19 are rotatably connected to an array of rollers 20. The two sets of rollers 20... 0 is used to clamp the composite flooring. A second servo motor is fixedly connected to one side of the U-shaped plate 7. The output shaft of the second servo motor is fastened to the bidirectional threaded rotating rod 15. During the polishing process, the composite flooring is smoothly and accurately transferred from the conveying station to the polishing station through the clamping of the roller 20 and the coordination of the first electric push rod 22. This ensures that the board enters the polishing area in a horizontal state, avoiding jamming and impact. Furthermore, the double polishing design of the first polishing block 10 and the second polishing block 31 on both sides significantly improves the surface smoothness and consistency.

[0032] Two vertical plates 19 are fixedly connected to the outer sides of a fixed plate 25. A first sliding rod 26 is slidably connected to one side of each fixed plate 25. One side of the first sliding rod 26 passes through the fixed plate 25 and extends to the other side. A wedge-shaped block 29 for supporting the composite flooring is fixedly connected to one side of each first sliding rod 26. A second spring 28 is fixedly connected between each wedge-shaped block 29 and the fixed plate 25. A first mounting block 27 is fixedly connected to the other side of each first sliding rod 26. A baffle 30 for limiting the composite flooring is fixedly connected to both ends of each wedge-shaped block 29. The wedge-shaped blocks 29 support the vertically upward-pointing composite flooring. When the output end of the first electric push rod 22 extends the connecting plate 24, the composite flooring compresses the two elastic wedge-shaped blocks 29, causing them to move relative to each other. This releases the limitation on the composite flooring, allowing it to proceed to the edge grinding and polishing process, making it convenient to use.

[0033] The processing table 14 is provided with inclined guide surfaces 42 around its perimeter. An inclined slide 16 is fixedly connected to one side of the first drive device 2. Four collection boxes 18 are fixedly connected to the upper side of the machine body 1. One side of the inclined slide 16 is located inside one of the collection boxes 18.

[0034] In use, the composite flooring is vertically placed onto two wedge-shaped blocks 29. At this point, the two wedge-shaped blocks 29 can initially support the composite flooring. Simultaneously, the two elastic first polishing blocks 10 also clamp and limit the composite flooring. Then, the second servo motor is activated, causing its output shaft to drive the bidirectional threaded rotor 15 to rotate. This allows the two vertical plates 19 on the bidirectional threaded rotor 15 to move towards each other, enabling the two sets of rollers 20 on the two vertical plates 19 to clamp the left and right ends of the composite flooring. This allows for clamping and positioning composite flooring of different sizes, and also enables polishing of different sizes. The composite flooring of the specified size is then moved by the first drive device 2, which drives the entire U-shaped frame 5 towards the mounting frame 3. At the same time, as the U-shaped frame 5 moves to a certain position, the coaxial connector 58 and guide wheel 59 of the first rotating shaft 6 can move along the trajectory of the cam groove 57, thereby realizing the automatic 90-degree flip of the U-shaped plate 7. At this time, the composite flooring changes from a vertical state to a horizontal state, and the two wedge blocks 29 face the mounting frame 3. This facilitates the subsequent comprehensive grinding and polishing of the two sides and four edges of the composite flooring by the surface treatment machine, improving the production efficiency of the surface treatment machine. By activating the second drive device 4, the two second polishing blocks 31 are driven to move towards each other, so that the distance between the two second polishing blocks 31 is adjusted to the thickness of the composite floor, so that the two sides of the composite floor can be polished in the future. Then, when the composite floor on the U-shaped frame 5 moves in front of the two second polishing blocks 31, the first drive device 2 is stopped. At this time, the second servo motor is activated, so that the output shaft of the second servo motor drives the bidirectional threaded rod 15 to reverse. In this way, the two vertical plates 19 on the bidirectional threaded rod 15 can move relative to each other, so that the two sets of rollers 20 change to a close but not clamped state. Then, the first electric push rod 22 is activated, so that the output end of the first electric push rod 22 drives the lifting frame 23 to move. In this way, the connecting plate 24 on one side of the lifting frame 23 can push the composite floor towards the two second polishing blocks 31. At the same time, the composite floor can pass through the position between the two first polishing blocks 10 and the two second polishing blocks 31 in sequence, so that the two sides of the composite floor can be polished. Finally, the connecting plate 24 can push the composite floor completely onto the rubber pad 43 above the processing table 14. Then, activate the two second electric actuators 39, causing their output ends to drive the third grinding blocks 40 closer to both ends of the composite flooring. Next, activate the third servo motor, causing its output shaft to drive the gear 34 below the second rotating shaft 33 to rotate clockwise or counterclockwise. At this time, the gear 34 can drive the two racks 37 to move towards each other or relative to each other. In this way, the two third grinding blocks 40 can grind and polish the edge burrs of the composite flooring back and forth. Then, activate the output shafts of the two second electric actuators 39 to drive the two third grinding blocks 40 away from the composite flooring. Finally, activate the fourth servo motor, causing its output shaft to drive... The top plate 54 above the third rotating shaft 41 rotates 90 degrees, adjusting the unpolished edge of the composite floor to the polishing area. At the same time, the output ends of the two second electric push rods 39 drive the third polishing blocks 40 to approach the two ends of the composite floor. Simultaneously, the two third polishing blocks 40 can grind and polish the edge of the composite floor back and forth, which is beneficial for polishing the entire composite floor from all angles. The entire polishing process does not require manual intervention, has a high degree of automation, improves the working efficiency of the surface treatment machine, and the double polishing and reciprocating polishing methods can improve the processing quality of the surface treatment machine. When the composite flooring is pushed into the rubber pad 43 using the connecting plate 24, the edge of the composite flooring will first contact the inclined surface below the upper inclined block 32. This allows the composite flooring to press the upper inclined block 32 upward, so that the composite flooring fits into the underside of the pressure block 51. Then, the elastic pressure block 51 can clamp and position the composite flooring above it. Subsequently, the first drive device 2 drives the U-shaped frame 5 to continue moving, so that the arc block 13 presses the elastic conical block 47. When the pressing is in place, the first drive device 2 can be stopped, allowing the conical block 47 to drive the suction cup 45 to move upward. This allows the suction cup 45 to adhere to the underside of the composite flooring, which helps to stably position the composite flooring and ensures the stability of the composite flooring during sanding and polishing, preventing it from shaking. At the same time, the inclined guide surface 42 and the inclined slide 16 around the processing table 14 allow the polishing debris to flow down and automatically flow into the collection box 18 to collect the debris and prevent debris accumulation.
