[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, the present invention proposes a ceramic roller surface flatness detection device, comprising a power assembly 1 and at least one set of test assemblies 2, wherein the test assembly 2 is arranged on the upper part of the power assembly 1; The power assembly 1 includes a motor, which is used to drive the ceramic roller 201 in the test assembly 2 to rotate; The test component 2 includes a sliding platform 202, an upper platform 209, two groups of rear movable columns 223 and a placement platform 225.

[0023] A set of placement platforms 225 is provided at the rear of each set of rear movable columns 223 , and the placement platforms 225 are used for placing paper.

[0024] like Figure 4 、 Figure 5 and Figure 6 As shown, the sliding platform 202 includes a first slide rail 203, a transverse sliding block 204, a second slide rail 205, a scale 206, a splint 207 and a probe 208. The first slide rail 203 is fixedly connected to the upper part of the sliding platform 202, the transverse sliding block 204 is movably connected to the upper part of the first slide rail 203, the upper part of the transverse sliding block 204 is fixedly connected to the second slide rail 205, the upper part of the second slide rail 205 is provided with a scale 206, the upper part of the second slide rail 205 is movably connected to the splint 207, and the front part of the splint 207 is detachably connected to the probe 208.

[0025] like Figure 4 、 Figure 5 、 Figure 6 and Figure 8 As shown, the upper platform 209 includes an observation port 210 , a lower hanging plate 211 , a roller 212 , a lower movable block 213 , a mounting hole 214 , a connecting column 215 , a spring 216 , a linkage plate 217 , and a placement port 218 .

[0026] like Figure 4 、 Figure 5 、 Figure 6 and Figure 8 As shown, the upper plate 209 is provided with an observation port 210, and the observation port 210 passes through the upper plate 209. A group of lower hanging plates 211 are fixedly connected to both sides of the upper plate 209. The front part of each group of the lower hanging plates 211 is rotatably connected to a roller 212, and the lower part of each group of the lower hanging plates 211 is provided with a group of linkage plates 217. The lower part of each group of the lower hanging plates 211 is provided with a group of lower movable blocks 213, and the upper part of each group of the lower movable blocks 213 is provided with a placement port 218, and the placement port 218 is used to place the ceramic roller 201. The rear part of each group of the lower movable blocks 213 is provided with two groups of mounting holes 214, and each group of the mounting holes 214 is provided with a group of connecting columns 215. The outside of each group of the connecting columns 215 is provided with a spring 216, and each group of the connecting columns 215 passes through the linkage plate 217.

[0027] like Figure 4 、 Figure 5 and Figure 6 As shown, the rear movable column 223 includes a transmission washer 219 , a movable column 220 , a movable rod 221 , a lower probe 222 and a movable connection block 224 .

[0028] like Figure 4 、 Figure 5 and Figure 6 As shown, the upper part of each group of the rear movable columns 223 is fixed with a movable connecting block 224, the middle part of each group of the movable connecting blocks 224 is rotatably connected to the movable rod 221, the rear part of each group of the movable rods 221 is detachably connected to the lower probe 222, the front part of the movable rod 221 is rotatably connected to the movable column 220, the lower part of the movable column 220 is fixed with a transmission gasket 219, and the transmission gasket 219 is placed on the upper platform 209.

[0029] In this embodiment, first, a V-shaped placement opening 218 is formed on the upper part of the lower movable block 213 through a grooving process. At this time, the ceramic roller 201 can be placed on the placement opening 218, and there is no other fixing device on the outside of the placement opening 218. At this time, if the ceramic roller 201 starts to rotate through external force, the ceramic roller 201 can rotate on the lower movable block 213.

[0030] At this time, the position of the lower movable block 213 in the power assembly 1 is taken as the origin, and then the position of the sliding platform 202 in the power assembly 1 is adjusted so that the sliding platform 202 is close to the lower movable block 213. Then, because the first slide rail 203 is fixed to the upper part of the sliding platform 202, the transverse sliding block 204 is movably connected to the upper part of the first slide rail 203. At this time, the transverse sliding block 204 can be pushed to make the transverse sliding block 204 slide along the first slide rail 203 on the sliding platform 202.

[0031] The upper part of the transverse sliding block 204 is fixedly connected to the second slide rail 205, and the upper part of the second slide rail 205 is movably connected to the splint 207. When the transverse sliding block 204 moves to a fixed position along the first slide rail 203, the splint 207 can be pushed to move along the second slide rail 205 on the transverse sliding block 204, and the front part of the splint 207 is fixedly connected to the probe 208. At this time, the splint 207 can be pushed to move the splint 207 with the probe 208 forward, and the front part of the probe 208 touches the ceramic roller 201.

[0032] A scale 206 is provided on the upper portion of the second slide rail 205. When the splint 207 moves forward with the probe 208 and the front portion of the probe 208 touches the ceramic roller 201, the reading of the scale 206 where the splint 207 is located can be checked and recorded.

[0033] If there is a defect in the middle of the ceramic roller 201, the position of the horizontal sliding block 204 and the splint 207 can be adjusted, and the front of the needle 208 on the front of the splint 207 can touch the ceramic roller 201. As the ceramic roller 201 rotates, the protrusion of the ceramic roller 201 will definitely touch the probe 208, and the probe 208 will retreat, driving the splint 207 to retreat. After retreating, the reading of the splint 207 on the scale 206 can be observed and compared with the previously recorded number. If the difference is large, it means that the ceramic roller 201 is unqualified.

[0034] If there are defects on both sides of the ceramic roller 201, the following detection process is performed: First, install the upper platen 209 on the upper part of the lower movable block 213, and then adjust the distance between the rear movable column 223 and the upper platen 209 so that the transmission gasket 219 at the front of the rear movable column 223 can be placed on the upper platen 209. Then start the power assembly 1 to make the power assembly 1 start to move, and the power assembly 1 provides power to make the ceramic roller 201 start to rotate.

[0035] At this time, if the cross-sectional radius of any side of the head and tail of the ceramic roller 201 is larger than the cross-sectional radius of the other side, or if there is a protrusion on the outer surface of any side, then when the ceramic roller 201 starts to rotate, it will move up and down. First, because the roller assembly 106 in the power assembly 1 is in a relatively stable motion state, the roller assembly 106 only rotates in the power assembly 1 without shaking up and down.

[0036] At this time, when the roller assembly 106 drives the ceramic roller 201 to rotate, as the ceramic roller 201 rotates, the roller assembly 106 will contact the part with a larger cross-sectional radius or the convex part of the outer surface, and because the roller assembly 106 always remains stationary in the horizontal direction, the ceramic roller 201 will be warped because the convex part contacts the roller assembly 106, causing the cross-sectional radius or the side with the convexity on the outer surface to rise.

[0037] A group of lower hanging plates 211 are fixedly connected to both sides of the upper plate 209, and the front part of each group of lower hanging plates 211 is rotatably connected to a roller 212. At this time, the roller 212 is located on the upper part of the ceramic roller 201 and contacts the ceramic roller 201. When the ceramic roller 201 rotates, due to the friction between the roller 212 and the ceramic roller 201, the roller 212 also starts to rotate. When the ceramic roller 201 is tilted on one side due to its own reasons during rotation, the other side will be pressed by the roller 212 to prevent the ceramic roller 201 from vibrating due to eccentricity during rotation, and eventually causing it to fall off.

[0038] When one side of the ceramic roller 201 is tilted up, the upper part of the ceramic roller 201 contacts the roller 212. At this time, the tilted ceramic roller 201 will drive the roller 212 to move upward, and the front part of the lower hanging plate 211 is rotatably connected to the roller 212. When the roller 212 moves upward, it will drive the lower hanging plate 211 on this side to move upward.

[0039] When the lower hanging plate 211 on this side moves upward, it will drive the upper platform 209 on this side to move upward. At this time, since a group of linkage plates 217 are provided at the lower part of the lower hanging plate 211, when the lower hanging plate 211 moves upward, the linkage plates 217 will also move upward. The connecting columns 215 all pass through the linkage plates 217, and the outside of the connecting columns 215 is provided with a spring 216, which means that the upper part of the spring 216 is connected to the linkage plate 217, and the lower part of the spring 216 is connected to the lower movable block 213.

[0040] When the linkage plate 217 is driven by the lower hanging plate 211 to move upward, the spring 216 below it will be pulled by the linkage plate 217, causing the spring 216 to accumulate elastic potential energy. When the ceramic roller 201 continues to rotate and there are no protrusions on its outer surface, the upper plate 209 on this side will not be lifted when the ceramic roller 201 contacts the ceramic roller 201. At this time, the spring 216 releases the accumulated elastic potential energy, pulling the linkage plate 217 connected to it to reset, and also the subsequent parts connected to the linkage plate 217 are reset.

[0041] The above movement will be repeated as the ceramic roller 201 continues to rotate. At this time, the transmission gasket 219 is placed on the upper platen 209. The continuous movement of the upper platen 209 will cause the transmission gasket 219 located thereon to move up and down repeatedly. The lower part of the movable column 220 is fixedly connected to the transmission gasket 219. At this time, driven by the transmission gasket 219 fixedly connected to the lower part of the movable column 220, the movable column 220 will move along with the movement of the transmission gasket 219.

[0042] The front part of the movable rod 221 is rotatably connected to the movable column 220. Driven by the movable column 220, the movable rod 221 will be lifted. At this time, the middle part of the movable connecting block 224 is rotatably connected to the movable rod 221. The rear part of the movable rod 221 is detachably connected to the lower probe 222. When the front part of the movable rod 221 is lifted, it is restricted by the movable connecting block 224, and the rear part of the movable rod 221 will drop. The drop of the rear part of the movable rod 221 will drive the lower probe 222 to drop.

[0043] Place paper on the placement platform 225 and color the lower probe 222. According to the above-mentioned movement principle, if there are colored spots on the paper on the placement platform 225, it means that the outer surface of the ceramic roller 201 is uneven, or there is an error in the diameter of its cross section. If there are no colored spots on the paper on the placement platform 225, it means that the surface of the ceramic roller 201 is smooth and can be used or sold directly.

[0044] As shown in FIG. 7 , the power assembly 1 includes a lifting assembly 101 , an external frame 102 , a lifting slide rail 103 , a sliding back plate 104 , a rotating frame 105 , a roller assembly 106 , a slide groove 107 and a limiter 108 .

[0045] As shown in Figure 7, a lifting assembly 101 is provided in the middle of the external frame 102, and a group of lifting slide rails 103 are provided on each side of the external frame 102. The sliding back plate 104 is movably connected to the front of the lifting slide rail 103. The front of the sliding back plate 104 is fixedly connected to a rotating frame 105. The internal rotation of the rotating frame 105 is connected to a roller assembly 106. A group of slide grooves 107 are provided on each side of the rotating frame 105, and the limiter 108 is provided on the upper part of any group of slide grooves 107.

[0046] like Figure 1 、 Figure 2 and Figure 3 As shown, the sliding platform 202 is movably connected to the upper part of the slide groove 107, and the upper part of each group of the slide grooves 107 is movably connected to a group of lower movable blocks 213, and the upper part of each group of the slide grooves 107 is movably connected to a group of rear movable columns 223.

[0047] In this embodiment, the lifting component 101 is connected to an external motor, so that the sliding back plate 104 can move up and down along the lifting rail 103 under the drive of the lifting component 101, and the sliding platform 202 is movably connected to the upper part of the slide groove 107, and the upper part of each group of slide grooves 107 is movably connected to a group of lower movable blocks 213, and the upper part of each group of slide grooves 107 is movably connected to a group of rear movable columns 223, so that the sliding platform 202, the lower movable blocks 213 and the rear movable columns 223 can be manually pushed.
