DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , a technical solution provided by the utility model:

[0027] A gypsum board corner grinding device comprises a base 1, a first positioning plate 2 and a second positioning plate 3 are fixedly connected to the top of the base 1, and the first positioning plate 2 and the second positioning plate 3 are used to position two adjacent side walls of a gypsum board body 5. A grinding mechanism 4 is connected to the first positioning plate 2 and the second positioning plate 3.

[0028] Specifically, the grinding mechanism 4 in this embodiment includes a triangular plate 41 located above the base 1, and the two sides of the triangular plate 41 are fixedly connected to the first positioning plate 2 and the second positioning plate 3 through connecting columns 42. There is a certain distance between the bottom surface of the triangular plate 41 and the top surface of the base 1, and the gypsum board body 5 can be inserted between the two.

[0029] The top of the triangle plate 41 is fixedly connected to a support frame 48, a rotating motor 49 is fixedly mounted on the support frame 48, a rotating shaft 410 is fixedly connected to the output end of the rotating motor 49, and the bottom end of the rotating shaft 410 is rotatably connected to the triangle plate 41. A transmission rod 411 is fixedly connected to the surface of the rotating shaft 410, a connecting rod 44 is slidably connected to the surface of the transmission rod 411, a guide wheel 43 is rotatably connected to the surface of the connecting rod 44, and the outer peripheral wall of the guide wheel 43 contacts a side wall of the triangle plate 41. A connecting spring 412 is sleeved on the outside of the transmission rod 411, and the two ends of the connecting spring 412 are respectively connected to the connecting rod 44 and the rotating shaft 410, so that the rotating shaft 410 and the connecting rod 44 are elastically connected. When in use, the rotating motor 49 drives the rotating shaft 410 to rotate, and the rotating shaft 410 drives the connecting rod 44 to swing through the transmission rod 411. During the swinging process, the guide wheel 43 is restricted by the triangle plate 41 and cannot make circular motion. Therefore, it will drive the connecting rod 44 in the opposite direction to slide on the surface of the transmission rod 411, so that the connecting spring 412 is stretched. When the guide wheel 43 rotates to the corner of the triangle plate 41, the connecting spring 412 is stretched to the longest state. Then, as the rotating shaft 410 continues to rotate, the connecting rod 44 and the guide wheel 43 will automatically reset under the elastic force of the connecting spring 412.

[0030] The surface of the connecting rod 44 is rotatably connected to a connecting frame 45, and a grinding assembly 46 is provided on the connecting frame 45 for grinding the side walls of the gypsum board body 5. During the grinding process, the grinding assembly 46 will move synchronously with the connecting frame 45 and the guide wheel 43. When the guide wheel 43 moves around the two side walls of the triangular plate 41, the grinding assembly 46 will move around the two side walls of the gypsum board body 5, and then automatically grind the two adjacent side walls of the gypsum board body 5, without frequently adjusting the angle of the gypsum board body 5 or the grinding assembly 46, thereby improving the grinding efficiency. Guidance is achieved through the cooperation of the guide wheel 43 and the triangular plate 41, rather than directly through the cooperation of the grinding assembly 46 and the gypsum board body 5. The distance between the grinding assembly 46 and the gypsum board body 5 can be reasonably controlled to avoid excessive grinding of the gypsum board body 5 by the grinding assembly 46.

[0031] In this embodiment, the grinding assembly 46 includes a folding plate 461 fixedly connected to the connecting frame 45, and the folding plate 461 is fixedly installed with a grinding motor 462. The output end of the grinding motor 462 is fixedly connected with a grinding wheel 463. The outer peripheral wall of the grinding wheel 463 contacts the side wall of the gypsum board body 5 to grind it.

[0032] It is worth noting that two adjacent side walls of the base 1 are provided with L-shaped grooves 11 , and the grinding wheel 463 moves in the grooves 11 , which can prevent the grinding wheel 463 from contacting the base 1 and causing damage to the grinding wheel 463 and the base 1 .

[0033] In addition, a clamping assembly 47 is provided on the triangular plate 41 for limiting the position of the gypsum board body 5 to improve stability during grinding.

[0034] like Figure 4 As shown, the clamping assembly 47 includes a slide bar 471 slidably connected to the inner wall of the triangular plate 41, a pressing plate 472 is slidably connected to the surface of the slide bar 471, and the bottom end of the slide bar 471 penetrates the pressing plate 472 and is fixedly connected to the contact plate 473. The outer sleeve of the slide bar 471 is provided with a support spring 474, and the two ends of the support spring 474 are respectively connected to the contact plate 473 and the pressing plate 472. By providing the support spring 474 and the contact plate 473, it is possible to avoid excessive pressure and damage to the gypsum board body 5. A screw rod 475 is transmission-connected to the inner wall of the pressure plate 472, and the top of the screw rod 475 is fixedly connected to the bottom end of the rotating shaft 410. When the rotating shaft 410 rotates, the screw rod 475 can be synchronously driven to rotate. At this time, the pressure plate 472 is limited by the sliding rod 471 and cannot make circular motion. Therefore, a spiral transmission is generated between the pressure plate 472 and the screw rod 475, so that the pressure plate 472 moves along the axial direction of the screw rod 475, thereby automatically descending to press and limit the gypsum board body 5.

[0035] When the gypsum board corner grinding device of the utility model is used, the gypsum board body 5 to be ground is first placed between the base 1 and the contact plate 473, so that the two side walls of the gypsum board body 5 are respectively fitted with the first positioning plate 2 and the second positioning plate 3. Then the grinding motor 462 and the rotating motor 49 are started, and the output end of the grinding motor 462 drives the grinding wheel 463 to rotate to grind the side walls of the gypsum board body 5. During the grinding process, the output end of the rotating motor 49 drives the rotating shaft 410 to rotate, and the rotating shaft 410 synchronously drives the screw 475 and the transmission rod 411 to rotate. The screw 475 drives the pressing plate 472 to move downward through the spiral rotation, and the pressing plate 472 drives the contact plate 473 to move downward through the supporting spring 474. The bottom surface of the contact plate 473 contacts the gypsum board body 5, and the gypsum board body 5 is pressed tightly to improve the stability during the grinding process.

[0036] In addition, the transmission rod 411 drives the connecting rod 44 to swing, and the connecting rod 44 drives the connecting frame 45, the guide wheel 43 and the grinding assembly 46 to swing synchronously. During the swinging process, the guide wheel 43 is restricted by the triangle plate 41 and cannot make a standard circular motion. Therefore, the guide wheel 43 will move at right angles along the edge of the triangle plate 41 under the dual effects of the torsion provided by the transmission rod 411 and the tension provided by the connecting spring 412. When the guide wheel 43 moves, it will synchronously drive the grinding assembly 46 to move at right angles along the side wall of the gypsum board body 5 through the connecting frame 45. The movement trajectory of the grinding assembly 46 is parallel to the movement trajectory of the guide wheel 43. During the movement, the grinding wheel 463 can grind the two side walls and a corner of the gypsum board body 5 without adjusting the position of the grinding assembly 46 or the gypsum board body 5 in the middle, thereby improving the grinding efficiency.
