When the plate is used in a desk, several sections of the plate need to be arranged and welded on a plane, that is, the side plates 2 of two adjacent plates need to be fitted and welded. Some plates are made of stainless steel and have paint on the surface, so before welding, the paint on the opposite side of the two side plates 2 of the plate needs to be polished off to ensure the welding effect between the plates.

DETAILED DESCRIPTION
[0034] The following is combined with Figure 2-4 This application is described in further detail.
[0035] Example 1
[0036] The present application embodiment discloses a plate paint grinding mechanism. Figure 2 and Figure 3 The plate paint grinding machine 6 includes a first grinding device 3 and a second grinding device 4, the first grinding device 3 and the second grinding device 4 are arranged at intervals along the horizontal direction, and the arrangement direction of the first grinding device 3 and the second grinding device 4 is horizontally perpendicular to the plate conveying direction; the first grinding device 3 is used to grind one side plate 2, and the second grinding device 4 is used to grind the other side plate 2.
[0037] In some embodiments, at least two first grinding devices 3 are arranged at intervals along the conveying direction of the plate, and at least two second grinding devices 4 are also arranged at intervals along the conveying direction of the plate. In this embodiment, two first grinding devices 3 and two second grinding devices 4 are arranged, so multiple grinding can be performed in the moving direction of the side panel 2 to ensure the effect of paint grinding on the side panel 2.
[0038] Among them, the first grinding device 3 and the second grinding device 4 both include a frame 5, a grinder 6 and an elastic reset assembly 7. The grinder 6 is a prior art, and the grinder 6 is connected to the frame 5 in a sliding manner in the horizontal direction, and the sliding direction of the grinder 6 is perpendicular to the plate conveying direction. The grinder 6 includes a body 61 and a grinding wheel 62, and the grinding wheel 62 is rotatably connected to the body 61, and the grinding wheel 62 and the body 61 are detachably installed; the grinding wheel 62 is selected as a shutter grinding wheel, and the rotating shaft of the grinding wheel 62 is arranged in the vertical direction, and the outer side of the grinding wheel 62 is in contact with the opposite side of the two side plates 2. After the body 61 is powered on, it is used to drive the grinding wheel 62 to rotate, thereby realizing paint grinding on the opposite sides of the two side plates 2.
[0039] Reference Figure 3 and Figure 4 The frame 5 is rotatably connected to a limiting wheel 8 at the bottom. The limiting wheel 8 is horizontally arranged. The rotation axis of the limiting wheel 8 is vertically arranged and is its own axis. The limiting wheel 8 is located on one side of the conveying direction of the side plate 2. The outer side of the limiting wheel 8 abuts against the outer side surfaces of the two side plates 2 that are away from each other. The grinding wheel 62 is horizontally opposite to the limiting wheel 8. When the grinding wheel 62 grinds the side plate 2, the side plate 2 passes through the gap between the grinding wheel 62 and the limiting wheel 8. The limiting wheel 8 is used to support the outer side of the side plate 2 to reduce the deformation of the side plate 2.
[0040] The elastic reset assembly 7 is disposed on the frame 5 , and is used to drive the grinder 6 to move toward the direction of being attached to the side plate 2 , so that the grinding wheel 62 maintains elastic contact with the inner side of the side plate 2 . When the cam 72 is in the closed position, the spring 72 is in the closed position, and the spring 72 is in the closed position, so that the cam 72 can be easily moved after the cam 72 is in the closed position, and the cam 72 can be easily moved after the cam 72 is in the closed position.
[0041] In other solutions, the spring 72 can also be replaced by an elastic rubber sleeve. A washer 9 is sleeved on the connecting rod 74, and the washer 9 is located on the side of the fastening nut 73 close to the spring 72. The area of the washer 9 is larger than the area of the spring 72. When the side area of the fastening nut 73 is small, it is ensured that the end of the spring 72 away from the limit plate 71 can be stably blocked.
[0042] In some embodiments, a convex ring 10 is fixed around the lower end of the limiting wheel 8 , and the convex ring 10 is coaxially arranged with the limiting wheel 8 . The convex ring 10 supports the lower end of the side plate 2 and the lower surface of the bottom plate 1 close to the side plate 2 .
[0043] In some embodiments, the frame 5 is rotatably connected with a roller 11, which is arranged in the horizontal direction, and the upper side of the roller 11 is in the same plane as the upper surface of the convex ring 10, and the roller 11 is located between the first grinding device 3 and the second grinding device 4. The rollers 11 on the first grinding device 3 and the second grinding device 4 are staggered along the conveying direction of the plate, and the rollers 11 are supported on the lower side of the bottom plate 1. Since the plate has a certain width, when the plate is conveyed and polished, the rollers 11 further ensure the stability of the side plate 2 during conveying and polishing.
[0044] In some embodiments, the frame 5 is horizontally slidably connected with a slide 12, and the slide 12 includes a fixed portion 121 and a disassembly portion 122. The fixed portion 121 is slidably connected to the frame 5 by means of a slide rail, and the connecting rod 74 is fixed to one side of the fixed portion 121. The sliding direction of the fixed portion 121 is consistent with the length direction of the connecting rod 74. The disassembly portion 122 is detachably connected to the fixed portion 121, and the disassembly portion 122 is locked to the side of the fixed portion 121 away from the connecting rod 74 by a plurality of bolts. The main body is clamped between the fixed portion 121 and the disassembly portion 122 to achieve rapid disassembly of the grinder 6, and facilitate disassembly and replacement of the grinding wheel 62.
[0045] The implementation principle of a plate paint grinding mechanism in the embodiment of the present application is as follows: when working, the plate is transported in the horizontal direction, wherein the first grinding device 3 is used to grind one of the side plates 2, and the second grinding device 4 is used to grind the other side plate 2. By rotating the abutting nut 73, the compression amount of the spring 72 can be adjusted to ensure that the grinding wheel 62 has sufficient abutting force on the side plate 2 to grind off the paint. Since the elastic reset component 7 can drive the grinding wheel 62 to move in the direction of being fitted to the inner side of the side plate 2, and the grinding wheel 62 of the grinder 6 is worn, as long as the spring 72 is still in a compressed state, the grinding wheel 62 still maintains a certain pressure to fit the side plate 2, ensuring that the grinding wheel 62 is continuously used for grinding, and realizing the convenience of automatically adjusting the position of the grinder 6, so that the grinding wheel 62 keeps in contact with the side plate 2, and reduces the frequency of replacement of the grinding wheel 62, thereby improving the utilization rate of the grinding wheel 62.
[0046] When the grinding wheel 62 is gradually worn, the pressure between the grinding wheel 62 and the side plate 2 can be ensured by continuing to rotate the nut 73 to ensure the compression of the spring 72, and the adjustment is convenient and fast. Moreover, it can also be better suitable for grinding the side plate of the plate with gradually changing bottom plate width.
