Description

Technical Field

[0001] The utility model relates to the technical field of deburring structures, in particular to a grinding and deburring structure for furniture solid wood panels. Background Art

[0002] In the process of producing and processing wood materials, removing burrs is an indispensable step. Burrs are tiny fibers, chips or partially separated wood caused by processes such as sawing, planing or grinding. The presence of burrs not only affects the appearance quality and smoothness of the wood board, but may also pose potential safety risks to processors or end users in subsequent applications, such as causing scratches.

[0003] According to the board deburring device proposed by Chinese patent announcement No. CN221792086U, by starting the fourth driving device, the fourth driving device drives the grinding wheel to rotate at high speed, and then deburrs the surface of the wooden board. By starting the first driving device to drive the grinding roller to rotate at high speed, the grinding roller can perform deburring on the side of the wooden board. Therefore, the surface and side of the wooden board can be deburred synchronously, thereby improving production efficiency, reducing equipment costs, and reducing equipment space. During use, the application document can grind and deburr the sides and surface of the board. However, in actual use, general boards mostly need to be grinded and deburred on both sides of the board during the deburring process, while the application document can only process one side of the board at a time. When grinding and deburring the other side, the wood needs to be turned over and reprocessed after entering the site. The operation is relatively cumbersome and reduces the efficiency of board deburring. Therefore, a furniture solid wood board grinding and deburring structure is proposed to solve the above problems.

For those skilled in the art, the specific meanings of the above terms in this utility model can be understood by those skilled in the art in specific circumstances.

[0025] like Figure 1-5As shown, the utility model proposes a furniture solid wood board grinding and deburring structure, including a base plate 1, a conveyor belt 2 is provided on the top of the base plate 1, two sets of side deburring mechanisms 3 are provided on the top of the base plate 1, and the two sets of side deburring mechanisms 3 are respectively located on the front and back sides of the conveyor belt 2, a gantry support frame 5 is provided on the top of the base plate 1, and a double-sided deburring mechanism 4 is provided on the top of the base plate 1 and located inside the gantry support frame 5.

[0026] In the present invention, solid wood boards can be transported by the conveyor belt 2, and the two sides of the boards can be polished and deburred during the board transportation process by the two sets of side deburring mechanisms 3, and the top and bottom of the boards can be polished and deburred by the gantry support frame 5 and the double-sided deburring mechanism 4. The side deburring mechanism 3 and the double-sided deburring mechanism 4 can polish and deburr both sides and both sides of the boards, which greatly improves the polishing and deburring efficiency of the boards.

[0027] In an optional embodiment, the double-sided deburring mechanism 4 includes a bottom surface grinding assembly 41, a fixed box 42, a lifting plate 43, a threaded sleeve 44, a threaded rod 45, a driving assembly 46, a limiting assembly 47, two guide rods 48 and a top surface grinding assembly 49. The bottom surface grinding assembly 41 is arranged on the top of the base plate 1, the fixed box 42 is arranged on the top of the gantry support frame 5, the lifting plate 43 is slidably connected to the inside of the gantry support frame 5, the threaded sleeve 44 is rotatably connected to the inner top wall of the fixed box 42 and extends to the inside of the gantry support frame 5, and the threaded rod 45 is screwed.

[0028] It should be noted that the bottom of the plate can be polished by the bottom surface polishing assembly 41, and the threaded sleeve 44 can be driven to rotate by the driving assembly 46. Under the action of the limit assembly 47 and the two guide rods 48, the lifting plate 43 will not rotate, so that the threaded rod 45 will not rotate. Therefore, when the threaded sleeve 44 rotates, under the action of the threaded thrust, the threaded rod 45 will move downward or upward, and the threaded rod 45 will drive the lifting plate 43 to move downward or upward, and the lifting plate 43 will drive the top surface polishing assembly 49 to move downward or upward. When the top surface polishing assembly 49 is in contact with the top of the plate, the top of the plate is polished and deburred by the top surface polishing assembly 49.

[0029] Specifically, the top and bottom surfaces of the plate can be fully polished and deburred through the bottom surface polishing component 41 and the top surface polishing component 49, which greatly improves the efficiency of polishing and deburring the plate.

[0031] It should be noted that when the plate is conveyed by the conveyor belt 2, the plate will move to the top of the lower grinding roller 414, and the bottom surface of the plate will contact the outer side of the lower grinding roller 414. At the same time, the first DC motor 412 is started, and the output shaft of the first DC motor 412 will drive the first rotating shaft 413 to rotate, and the first rotating shaft 413 will drive the lower grinding roller 414 to rotate. The rotation of the lower grinding roller 414 can fully grind and remove burrs on the bottom of the plate.

[0032] In an optional embodiment, the top surface grinding assembly 49 includes two second ear plates 491, a second DC motor 492, a second rotating shaft 493 and an upper grinding roller 494. The two second ear plates 491 are both arranged at the bottom of the lifting plate 43, the second DC motor 492 is arranged on the back side of the second ear plate 491 on the back side, the second rotating shaft 493 is arranged on the output shaft of the second DC motor 492, the second rotating shaft 493 extends to the front side of the second ear plate 491 on the back side and is rotatably connected to the back side of the second ear plate 491 on the front side, and the upper grinding roller 494 is arranged on the outside of the second rotating shaft 493.

[0033] It should be noted that, according to the thickness of the plate, the top surface grinding assembly 49 is driven downward by the driving assembly 46, so that when the bottom surface of the plate contacts the outer side of the lower grinding roller 414, the top of the plate will simultaneously contact the outer side of the upper grinding roller 494, and then the second DC motor 492 is started, and the output shaft of the second DC motor 492 will drive the second rotating shaft 493 to rotate, and the second rotating shaft 493 will drive the upper grinding roller 494 to rotate, and the top surface of the plate can be ground and deburred by the upper grinding roller 494.

[0034] In an optional embodiment, the drive assembly 46 includes a servo motor 461, a rotating rod 462, a worm 463 and a worm wheel 464. The servo motor 461 is arranged on the back of the fixed box 42, the rotating rod 462 is arranged on the output shaft of the servo motor 461 and extends to the interior of the fixed box 42, the worm 463 is arranged on the outside of the rotating rod 462, and the worm wheel 464 is arranged on the outside of the threaded sleeve 44, and the worm 463 is engaged with the worm wheel 464.

The two limit blocks 471 are respectively slidably connected to the two limit slots 472.

[0037] It should be noted that the lifting plate 43 can be guided by two guide rods 48 to ensure the stability of the movement of the lifting plate 43 and prevent the lifting plate 43 from rotating. During the movement of the lifting plate 43, the lifting plate 43 can be limited by two limit blocks 471 and two limit grooves 472 to avoid the lower grinding roller 414 and the upper grinding roller 494 from being limited.

[0038] In an optional embodiment, a support block 6 is provided on the top of the base plate 1 , the top of the support block 6 corresponds to the top position of the conveyor belt 2 , and a controller 7 is provided on the front of the gantry support frame 5 .

[0039] It should be noted that the support block 6 can support the deburred plate to prevent the plate from being in too close contact with the lower grinding roller 414, which would affect the normal transmission of the plate and thus affect the grinding and deburring effect of the plate.
