Description

Technical Field

[0001] The utility model relates to the field of furniture plate processing, in particular to a plate surface grinding device. Background Art

[0002] Furniture boards are usually fixed on indoor walls to protect and decorate the walls. During the processing of furniture boards, the surface of the raw materials of the furniture boards must first be polished, and then subsequent processing such as painting and laminating can be carried out after polishing. Different furniture boards have different widths, but the adjustable range of the board fixing mechanism of the existing polishing device is small, resulting in instability when fixing narrower board materials, or even inability to fix, thereby affecting the polishing effect of the surface of the board material. The traditional way to increase the fixing range is to increase the length of the fixing mechanism, but this will increase the width of the polishing device, resulting in an increase in floor space.

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] In the drawings, the same reference numerals all refer to the same components.

[0021] like Figure 1-4 As shown, the utility model provides a plate surface grinding device, including a frame 1, a gantry 5 and an electric grinding disc 6, linear guide rails 7 are respectively provided on both sides of the frame 1, and both sides of the gantry 5 are respectively arranged on the sliding seats of the two linear guide rails 7, a translation component 2 is provided on the gantry 5, the electric grinding disc 6 is arranged below the gantry 5 and connected to the sliding part of the translation component 2, a roller conveying mechanism 8 is provided in the frame 1, two groups of first fixed components 3 are provided on the top of the frame 1, and the two groups of first fixed components 3 are respectively located on both sides of the gantry 5, and two groups of second fixed components 4 are provided in the frame 1 and are located below the roller conveying mechanism 8, and the positions of the two groups of second fixed components 4 correspond to the positions of the two groups of first fixed components 3.

[0022] In this embodiment, the plate material with grinding is transported by a roller conveyor mechanism 8 using the prior art in the frame 1, and stops when the plate material is transported to the bottom of the gantry 5;

[0023] When the width of the plate material is large, two sets of first fixing components 3 are used to fix the two sides of the plate material, and then the height of the electric grinding disc 6 using the prior art is adjusted so that the electric grinding disc 6 contacts the surface of the plate material and then starts grinding. The gantry 5 is driven to move along the length direction of the frame 1 by using the linear guide rail 7 of the prior art, and the electric grinding disc 6 is driven to move along the width direction of the frame 1 by the translation component 2, so that the electric grinding disc 6 can move on the surface of the plate material and grind;

[0024] When the width of the plate material is small, the two sides of the plate material are fixed respectively by one side of two groups of first fixing components 3 and two groups of second fixing components 4, and then the height of the electric grinding disc 6 using the prior art is adjusted so that the electric grinding disc 6 contacts the surface of the plate material and then starts grinding. The gantry 5 is driven to move along the length direction of the frame 1 by using the linear guide rail 7 of the prior art, and the electric grinding disc 6 is driven to move along the width direction of the frame 1 by the translation component 2, so that the electric grinding disc 6 can move and grind on the surface of the plate material.

[0025] Furthermore, the translation assembly 2 includes a screw rod 21, a motor 22 and a slider 23. A through groove is opened at the top of the gantry 5. The screw rod 21 is horizontally arranged in the through groove, and its two ends are rotatably connected to the inner wall of the through groove through bearings. The slider 23 is arranged in the through groove and is threadedly connected to the screw rod 21. The motor 22 is arranged on the outer wall of the gantry 5, and its output shaft is transmission-connected to the screw rod 21. The bottom end of the slider 23 is provided with a first electric cylinder 24 facing vertically downward, and the electric grinding disc 6 is horizontally arranged at the end of the piston rod of the first electric cylinder 24.

[0026] In this embodiment, the motor 22 drives the screw rod 21 to rotate in the through groove, and drives the slider 23 to translate in the through groove, thereby driving the electric grinding disc 6 to move horizontally along the width direction of the frame 1. The height of the electric grinding disc 6 can be adjusted by the first electric cylinder 24 to adapt to plate materials of different thicknesses.

[0027] Furthermore, the translation assembly 2 also includes two optical axes 25, which are horizontally arranged in the through groove, and both ends of the two optical axes 25 are fixedly connected to the inner wall of the through groove and are respectively located on both sides of the screw rod 21, and the slider 23 is slidably connected to the two optical axes 25.

[0028] In this embodiment, the two optical axes 25 can increase the sliding stability of the slider 23 in the through groove.

[0029] Furthermore, the first fixing assembly 3 includes two first cylinders 31, and the two first cylinders 31 are respectively arranged on both sides of the top of the frame 1, and the piston rods of both are horizontally arranged toward the inner side of the frame 1. The end of the piston rod of each first cylinder 31 is vertically fixed with a first fixing plate 32, and the two first fixing plates 32 are both located in the gap between adjacent rollers of the roller conveyor mechanism 8.

[0030] In this embodiment, when the piston rod of the first cylinder 31 is retracted, it is convenient to transport the sheet material on the roller conveyor mechanism 8. When the piston rod of the first cylinder 31 is extended, it is possible to drive the corresponding first fixing plate 32 to contact the side of the sheet material, thereby fixing the sheet material.

[0031] The first fixing plate 32 is located at the gap between two adjacent rollers of the roller conveying mechanism 8 , so that the first fixing plate 32 can fix the plate material conveniently.

[0032] Furthermore, the second fixed assembly 4 includes a support plate 41, a second cylinder 42, a second fixed plate 43 and two second electric cylinders 44. The two second electric cylinders 44 are arranged on the bottom wall of the frame 1, and the piston rods of both are arranged vertically upward. The support plate 41 is arranged at the ends of the piston rods of the two second electric cylinders 44. The second cylinder 42 is horizontally arranged at the top of the support plate 41, and its piston rod is arranged toward the side wall of the frame 1. The second fixed plate 43 is vertically arranged at the ends of the piston rods of the second cylinders 42, and it is located at the gap between the rollers corresponding to the first fixed plate 32.

[0033] In this embodiment, when fixing a sheet material with a larger width, the second fixing assembly 4 is not required to participate, so the piston rods of the two second electric cylinders 44 are retracted, so that the top end of the second fixing plate 43 is located below the top end of the circumferential surface of the roller of the roller conveying mechanism 8 to avoid contact with the sheet material;

[0034] When fixing a sheet material with a smaller width, the second electric cylinder 44 drives the support plate 41 to lift, and makes the top end of the second fixed plate 43 extend out of the top end of the circumferential surface of the roller of the roller conveyor mechanism 8, and then the second fixed plate 43 is driven by the second cylinder 42 to move toward the side wall of the sheet material. At the same time, the first cylinder 31 on one side of the first fixing component 3 drives the first fixed plate 32 to move toward the side wall of the sheet material, and the two sides of the sheet material with a smaller width are fixed respectively by the first fixed plate 32 and the second fixed plate 43.

[0035] Furthermore, a supporting plate 9 is provided at the top of the second fixed plate 43 and the bottom of each first fixed plate 32 , and the top surface of the supporting plate 9 is flush with the upper end of the circumferential surface of the roller of the roller conveying mechanism 8 .

[0036] In this embodiment, when the first fixing plate 32 or the second fixing plate 43 fixes the plate material, the supporting plate 9 can play a certain supporting role on the bottom end of the plate material to increase stability during grinding.

[0037] The utility model relates to a plate surface grinding device. When grinding a plate material with a larger width, the device fixes the plate material through two groups of first fixing components. When grinding a plate material with a smaller width, two groups of second fixing components extend from between rollers through second electric push rods and cooperate with one side of the first fixing components to fix the plate material. Thus, the device can adapt to plate materials of different widths without increasing the width of the grinding device.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
