[0002] In the field of construction engineering, the strength of building panels is a key indicator that determines the quality and safety of the project, and the accuracy and efficiency of its detection are crucial.

[0003] At present, there are many defects in traditional building board strength testing devices. On the one hand, most devices rely on manual feeding, which not only consumes a lot of manpower, but also has a slow feeding speed and low efficiency, making it difficult to meet the testing needs of large-scale production. At the same time, manual operation is prone to introduce subjective errors, affecting the reliability of the test results. On the other hand, the existing devices have a single way of fixing the board, and are unable to accurately fix the board in the horizontal and vertical directions at the same time. During the strength test process, the board is prone to displacement or shaking, resulting in inaccurate test data and an inability to truly reflect the strength performance of the board.

[0027] Example 1

[0028] See also Figure 1-3 , a building board strength testing device includes a supporting base 1, an automatic feeding assembly 2 and a detection assembly 3, wherein the automatic feeding assembly 2 and the detection assembly 3 are both connected to the supporting base 1; the automatic feeding assembly 2 includes a pushing part and a feeding part, and the pushing part includes a pushing vertical rod 211, which continuously pushes the board to be tested to the testing station of the detection assembly 3 through the left and right reciprocating linear motion of the pushing vertical rod 211; the detection assembly 3 includes a clamping part and a detection part. During the pushing process of the pushing vertical rod 211, the clamping part synchronously positions the horizontal and vertical edges of the board through a transmission mechanism, and the pressure sensor 330 of the detection part presses down to perform a strength test; when the pushing vertical rod 211 is reset, the clamping part releases the board, and the pressure sensor 330 is lifted up to reset

[0029] The automatic feeding assembly 2 also includes an installation vertical plate 201, an installation frame 202, a material discharge horizontal plate 203, a material limiting vertical plate 204 and an installation cross bar 205. The front and rear sides of the support base 1 are fixedly connected with the installation vertical plates 201, and the installation cross bar 205 is rotatably connected between the installation vertical plates 201. The installation frame 202 is fixedly connected to the installation vertical plate 201, and the material discharge horizontal plate 203 is fixedly connected to the side of the installation frame 202. The four corners of the top surface of the material discharge cross bar are fixedly connected to the material limiting vertical plate 204 to form a plate stacking and placement area.

[0030] The pushing part includes a pushing trough 206, a pushing slide rail 207, a pushing slider 208, a connecting cross bar 209, a connecting cross plate 210, a pushing vertical rod 211, an installation bottom block 212, a pushing vertical plate 213, a pushing chute 214, a reset vertical plate 215, a reset spring 216, a pushing wheel 217 and a half-moon wheel 218. The discharging cross plate 203 is provided with a pushing trough 206, and the bottom surface of the discharging cross plate 203 is fixedly connected with two groups of pushing slide rails 207 symmetrically arranged on both sides of the pushing trough 206. The pushing slide rails 207 are slidably connected with the pushing sliders 208. The two groups of pushing sliders 208 are fixedly connected by the connecting cross bar 209. The top surface of the pushing slider 208 is fixedly connected with the connecting cross plate 210. The top surface of the connecting cross plate 210 is fixedly connected. It is connected to a pushing vertical rod 211, the upper end of the pushing vertical rod 211 passes through the pushing groove 206, and the supporting base 1 is fixedly connected to a mounting bottom block 212, and the front side of the mounting bottom block 212 is rotatably connected to a pushing vertical plate 213, and a pushing chute 214 is provided on the pushing vertical plate 213. The connecting cross bar 209 is slidably connected to the pushing chute 214, and the bottom surface of the discharging cross plate 203 is fixedly connected to a reset vertical plate 215, and the side of the reset vertical plate 215 is fixedly connected to a reset spring 216, and the other end of the reset spring 216 is fixedly connected to the side of the pushing vertical plate 213, and the front side of the pushing vertical plate 213 is fixedly connected to a pushing wheel 217, and a half-moon wheel 218 is fixedly connected to the mounting cross bar 205, and the outer edge of the pushing wheel 217 abuts against the outer edge of the half-moon wheel 218.

[0031] The feeding part includes an upper feeding block 219, a lower feeding block 220, a limit block 221, a telescopic rod 222, a plate spring 223, a feeding cross bar 224 and a feeding roller 225. The bottom surface of the inner part of the mounting frame 202 is fixedly connected to the lower feeding block 220, and the top surface of the lower feeding block 220 is fixedly connected to the limit block 221. The top surface of the inner part of the mounting frame 202 is fixedly connected to the telescopic rod 222 and the plate spring 223. The lower ends of the telescopic rod 222 and the plate spring 223 are fixedly connected to the upper feeding block 219. The feeding cross bar 224 is rotatably connected between the upper feeding block 219 and the lower feeding block 220, and the feeding roller 225 is fixedly connected to the feeding cross bar 224.

[0032] The automatic feeding assembly 2 also includes a driving wheel 226, a reduction wheel 227 and a reduction belt 228. One end of the feeding cross bar 224 rotatably connected to the lower feeding block 220 passes through the lower feeding block 220 and is fixedly connected to the driving wheel 226. One end of the mounting cross bar 205 passes through the mounting vertical plate 201 and is fixedly connected to the reduction wheel 227. The driving wheel 226 and the reduction wheel 227 are connected by a reduction belt 228.

[0033] When the drive power is activated, it drives the feed bar 224, which is rotatably connected to the lower feed block 220, to rotate. The feed bar 224 transmits power to the mounting bar 205 via the drive wheel 226, speed reduction belt 228, and speed reduction wheel 227, causing the mounting bar 205 to begin rotating. The mounting bar 205 then drives the semi-moon wheel 218 fixed to it to rotate as well.

[0034] When the half-moon wheel 218 rotates with the mounting crossbar 205, its unique semicircular profile contacts the outer edge of the pusher wheel 217 on the front side of the pusher vertical plate 213. As the half-moon wheel 218 rotates, the gradually increasing radius of the half-moon wheel 218 pushes the pusher wheel 217, thereby causing the pusher vertical plate 213 to rotate around the mounting base 212. When the pusher vertical plate 213 rotates, the pusher chute 214 provided thereon and the connecting crossbar 209 slide relative to each other. Because the two sets of pusher slides 208 are fixedly connected by the connecting crossbar 209 and the pusher slides 208 slide in conjunction with the pusher rail 207, this relative sliding causes the pusher slides 208 to perform linear motion on the pusher rail 207. The connecting crossbar 210 and the pusher vertical rod 211, which are fixedly connected to the top surface of the pusher slide 208, also move synchronously, causing the pusher vertical rod 211 to perform linear motion within the pusher chute 206 from its initial position toward the detection component 3. As the pushing vertical rod 211 moves forward, its upper end will contact the plates stacked on the discharge horizontal plate 203, and relying on its own thrust, it will push the frontmost plate along the feeding direction to the receiving horizontal plate 302 of the detection component 3, completing a plate pushing action.

[0035] As the half-moon wheel 218 continues to rotate, the radius of the portion in contact with the pusher wheel 217 gradually decreases, and the thrust on the pusher wheel 217 also weakens. At this time, the reset spring 216, which is pre-connected between the reset vertical plate 215 on the bottom surface of the discharge horizontal plate 203 and the pusher vertical plate 213, releases its elastic potential energy due to elastic deformation caused by the stretching during the previous pushing process. Under the pulling force of the reset spring 216, the pusher vertical plate 213 rotates in the opposite direction around the mounting base 212. The pusher chute 214 drives the pusher slider 208 to slide to its initial position on the pusher rail 207 through the connecting crossbar 209. After the pusher vertical rod 211 is reset, it waits for the next rotation of the half-moon wheel 218 to enter the next pushing cycle, thereby achieving continuous and automatic pushing of the plates to be inspected.

[0036] When the feed crossbar 224 rotates, the feed roller 225 fixed to it rotates synchronously. The telescopic rod 222 and the plate spring 223, fixedly connected to the top surface of the mounting frame 202, are connected at their lower ends to the upper feed block 219, forming an adaptive adjustment structure. When plates of different thicknesses are placed on the feed roller 225, they exert pressure on the upper feed block 219 above. Thicker plates compress the telescopic rod 222, causing the plate spring 223 to deform under force, moving the upper feed block 219 upward and increasing the height of the feed channel. Thinner plates cause the upper feed block 219 to move downward under the elastic force of the plate spring 223, reducing the height of the feed channel.

[0037] Example 2

[0038] The present embodiment further adds the following improvements on the basis of the embodiment 1: the detection component 3 also includes a fixed vertical rod 301, a material receiving horizontal plate 302, a fixed vertical plate 303, a fixed frame 304, a horizontal slide 305, a longitudinal slide 306, a transmission wheel 307, a driven wheel 308, a transmission belt 309, a transmission horizontal rod 310, a limiting vertical rod 311, a driving horizontal plate 312, a driving disc 313 and a top plate 314, the four corners of the bottom surface of the material receiving horizontal plate 302 are fixedly connected to the fixed vertical rod 301, the lower end of the fixed vertical rod 301 is fixedly connected to the support base 1, the four corners of the material receiving horizontal plate 302 are provided with longitudinal slides 306, and horizontal slides 305 are provided on the left and right sides, the material receiving horizontal plate 302 is fixedly connected to The fixing frame 304 and the supporting base 1 are fixedly connected with two groups of fixed vertical plates 303 and two groups of limiting vertical rods 311, and the limiting vertical rods 311 are slidably connected with a driving cross plate 312. A transmission cross bar 310 is rotatably connected between the fixed vertical plates 303. The other end of the mounting cross bar 205 passes through the mounting vertical plate 201 and is fixedly connected to a transmission wheel 307. One end of the transmission cross bar 310 passes through the fixed vertical plate 303 and is fixedly connected to a driven wheel 308. The driven wheel 308 and the transmission wheel 307 are connected by a transmission belt 309. A driving disc 313 is fixedly connected to the transmission cross bar 310, and a top plate 314 is fixedly connected to the outer edge of the driving disc 313. The top plate 314 abuts against the bottom surface of the driving cross plate 312.

[0039] When the push rod 211 of the automatic feeding assembly 2 pushes the sheet material to the receiving horizontal plate 302, the mounting crossbar 205, driven by the feeding unit, continues to rotate, transmitting the rotational power to the transmission crossbar 310 via the transmission wheel 307, the transmission belt 309, and the driven wheel 308. The transmission crossbar 310 drives the driving disc 313 and the incomplete gear 326 to rotate, providing power to the clamping unit and the detection unit respectively.

[0040] The clamping part includes a first fixed seat 315, a push plate wheel 316, a second fixed seat 317, a longitudinal cross bar 318, a longitudinal spring 319, a longitudinal vertical rod 320, a longitudinal splint 321, a longitudinal connecting plate 322, a longitudinal inclined plate 323 and a transverse positioning plate 324. The four corners of the top surface of the driving cross bar are fixedly connected to the first fixed seat 315, and the transverse positioning plates 324 are fixedly connected to the left and right sides of the top surface. The inner side of the first fixed seat 315 is fixedly connected to the push plate wheel 316, and the longitudinal vertical rod 320 is slidably connected in the longitudinal slot 306. The upper end of the longitudinal vertical rod 320 passes through the longitudinal slot 306 and is fixedly connected to the longitudinal splint 321. The lower end of the longitudinal vertical rod 320 located on the same side passes through the longitudinal slide groove 306 and is fixedly connected to the longitudinal connecting plate 322. The left and right sides of the bottom surface of the longitudinal connecting plate 322 are fixedly connected to the longitudinal inclined plates 323 that are retracted toward the middle. The bottom surface of the longitudinal inclined plates 323 is connected to the push plate wheel 316. The bottom surface of the material receiving cross plate 302 is fixedly connected to two groups of second fixed seats 317. The second fixed seats 317 are fixedly connected to the longitudinal cross rod 318 and the longitudinal spring 319. The end of the longitudinal cross rod 318 passes through the longitudinal connecting plate 322 and is slidably connected to the longitudinal connecting plate 322. The other end of the longitudinal spring 319 is fixedly connected to the longitudinal connecting plate 322.

[0041] The transmission crossbar 310 rotates the drive disc 313. When the top plate 314 on the outer edge of the drive disc 313 rotates until it contacts the bottom surface of the drive cross plate 312, pushing the drive cross plate 312 upward, the clamping mechanism begins to operate. The drive cross plate 312 rises, driving the first fixed seats 315 at the four corners of the top surface and the inner push plate wheels 316 to move upward synchronously. After the push plate wheels 316 contact the longitudinal inclined plates 323 on the bottom surface of the longitudinal connecting plate 322, as the drive cross plate 312 continues to rise, the push plate wheels 316 roll along the inclined surface, generating a horizontal force component that pushes the longitudinal connecting plate 322 toward the plate. The longitudinal connecting plate 322 drives the longitudinal vertical rod 320 to slide in the longitudinal slide groove 306, so that the longitudinal clamping plate 321 tightly clamps the front and rear sides of the plate; in the process of driving the horizontal plate 312 to rise, the horizontal positioning plates 324 on the left and right sides of its top surface pass through the horizontal slide groove 305 of the material receiving horizontal plate 302, rise to contact and position with the left and right ends of the plate, and cooperate with the longitudinal clamping plate 321 to firmly fix the plate in the inspection station from both horizontal and vertical dimensions.

[0042] The detection part includes a fixed horizontal plate 325, an incomplete gear 326, a detection rack 327, a detection horizontal bar 328, a detection vertical bar 329 and a pressure sensor 330. The support base 1 is fixedly connected to the fixed horizontal plate 325, and the fixed horizontal plate 325 is elastically connected to the detection rack 327 set in a vertical direction. The other end of the transmission horizontal bar 310 passes through the mounting vertical plate 201 and is fixedly connected to the incomplete gear 326. The incomplete gear 326 is meshed with the detection rack 327. The upper end of the detection rack 327 is fixedly connected to the detection horizontal bar 328, and the end of the detection horizontal bar 328 is fixedly connected to the detection vertical bar 329. The lower end of the detection vertical bar 329 passes through the fixed frame 304 and is fixedly connected to the pressure sensor 330.

[0043] As the transmission crossbar 310 rotates, the partially enclosed gear 326 affixed thereto rotates synchronously. When partially enclosed gear 326 engages with the detection rack 327, the rotation of partially enclosed gear 326 drives the detection rack 327 downward in a vertical direction. The detection rack 327, through the detection crossbar 328 and the detection vertical rod 329, drives the pressure sensor 330 downward, applying pressure to the fixed plate to perform a strength test.

[0044] When the incomplete gear 326 rotates to a position where it is disengaged from the detection rack 327, the detection rack 327, due to its elastic connection with the fixed cross plate 325, automatically resets upward under the action of the elastic force, driving the pressure sensor 330 to lift up, completing a detection action. At the same time, the drive disc 313 continues to rotate, and the top plate 314 no longer supports the drive cross plate 312. The drive cross plate 312 moves downward and resets under the action of its own gravity. During the reset process of the drive cross plate 312, the push plate wheel 316 disengages from the longitudinal inclined plate 323, and the longitudinal spring 319 releases its elastic potential energy, driving the longitudinal connecting plate 322 and the longitudinal clamping plate 321 to reset, loosening the clamping of the plate; the horizontal positioning plate 324 descends with the drive cross plate 312, exits the horizontal chute 305, and releases the horizontal positioning of the plate. At this point, the detection component 3 completes a complete detection cycle and waits for the next plate to enter the detection station.

[0045] How it works

[0046] When the drive power is activated, it drives the feed bar 224, which is rotatably connected to the lower feed block 220, to rotate. The feed bar 224 transmits power to the mounting bar 205 via the drive wheel 226, speed reduction belt 228, and speed reduction wheel 227, causing the mounting bar 205 to begin rotating. The mounting bar 205 then drives the semi-moon wheel 218 fixed to it to rotate as well.

[0047] When the half-moon wheel 218 rotates with the mounting crossbar 205, its unique semicircular profile contacts the outer edge of the pusher wheel 217 on the front side of the pusher vertical plate 213. As the half-moon wheel 218 rotates, the gradually increasing radius of the half-moon wheel 218 pushes the pusher wheel 217, thereby causing the pusher vertical plate 213 to rotate around the mounting base 212. When the pusher vertical plate 213 rotates, the pusher chute 214 provided thereon and the connecting crossbar 209 slide relative to each other. Because the two sets of pusher slides 208 are fixedly connected by the connecting crossbar 209 and the pusher slides 208 slide in conjunction with the pusher rail 207, this relative sliding causes the pusher slides 208 to perform linear motion on the pusher rail 207. The connecting crossbar 210 and the pusher vertical rod 211, which are fixedly connected to the top surface of the pusher slide 208, also move synchronously, causing the pusher vertical rod 211 to perform linear motion within the pusher chute 206 from its initial position toward the detection component 3. As the pushing vertical rod 211 moves forward, its upper end will contact the plates stacked on the discharge horizontal plate 203, and relying on its own thrust, it will push the frontmost plate along the feeding direction to the receiving horizontal plate 302 of the detection component 3, completing a plate pushing action.

[0048] As the half-moon wheel 218 continues to rotate, the radius of the portion in contact with the pusher wheel 217 gradually decreases, and the thrust on the pusher wheel 217 also weakens. At this time, the reset spring 216, which is pre-connected between the reset vertical plate 215 on the bottom surface of the discharge horizontal plate 203 and the pusher vertical plate 213, releases its elastic potential energy due to elastic deformation caused by the stretching during the previous pushing process. Under the pulling force of the reset spring 216, the pusher vertical plate 213 rotates in the opposite direction around the mounting base 212. The pusher chute 214 drives the pusher slider 208 to slide to its initial position on the pusher rail 207 through the connecting crossbar 209. After the pusher vertical rod 211 is reset, it waits for the next rotation of the half-moon wheel 218 to enter the next pushing cycle, thereby achieving continuous and automatic pushing of the plates to be inspected.

[0049] When the feed crossbar 224 rotates, the feed roller 225 fixed to it rotates synchronously. The telescopic rod 222 and the plate spring 223, fixedly connected to the top surface of the mounting frame 202, are connected at their lower ends to the upper feed block 219, forming an adaptive adjustment structure. When plates of different thicknesses are placed on the feed roller 225, they exert pressure on the upper feed block 219 above. Thicker plates compress the telescopic rod 222, causing the plate spring 223 to deform under force, moving the upper feed block 219 upward and increasing the height of the feed channel. Thinner plates cause the upper feed block 219 to move downward under the elastic force of the plate spring 223, reducing the height of the feed channel.

[0050] When the push rod 211 of the automatic feeding assembly 2 pushes the sheet material to the receiving horizontal plate 302, the mounting crossbar 205, driven by the feeding unit, continues to rotate, transmitting the rotational power to the transmission crossbar 310 via the transmission wheel 307, the transmission belt 309, and the driven wheel 308. The transmission crossbar 310 drives the driving disc 313 and the incomplete gear 326 to rotate, providing power to the clamping unit and the detection unit respectively.

[0051] The transmission crossbar 310 rotates the drive disc 313. When the top plate 314 on the outer edge of the drive disc 313 rotates until it contacts the bottom surface of the drive cross plate 312, pushing the drive cross plate 312 upward, the clamping mechanism begins to operate. The drive cross plate 312 rises, driving the first fixed seats 315 at the four corners of the top surface and the inner push plate wheels 316 to move upward synchronously. After the push plate wheels 316 contact the longitudinal inclined plates 323 on the bottom surface of the longitudinal connecting plate 322, as the drive cross plate 312 continues to rise, the push plate wheels 316 roll along the inclined surface, generating a horizontal force component that pushes the longitudinal connecting plate 322 toward the plate. The longitudinal connecting plate 322 drives the longitudinal vertical rod 320 to slide in the longitudinal slide groove 306, so that the longitudinal clamping plate 321 tightly clamps the front and rear sides of the plate; in the process of driving the horizontal plate 312 to rise, the horizontal positioning plates 324 on the left and right sides of its top surface pass through the horizontal slide groove 305 of the material receiving horizontal plate 302, rise to contact and position with the left and right ends of the plate, and cooperate with the longitudinal clamping plate 321 to firmly fix the plate in the inspection station from both horizontal and vertical dimensions.

[0052] As the transmission crossbar 310 rotates, the partially enclosed gear 326 affixed thereto rotates synchronously. When partially enclosed gear 326 engages with the detection rack 327, the rotation of partially enclosed gear 326 drives the detection rack 327 downward in a vertical direction. The detection rack 327, through the detection crossbar 328 and the detection vertical rod 329, drives the pressure sensor 330 downward, applying pressure to the fixed plate to perform a strength test.

[0053] When the incomplete gear 326 rotates to a position where it is disengaged from the detection rack 327, the detection rack 327, due to its elastic connection with the fixed cross plate 325, automatically resets upward under the action of the elastic force, driving the pressure sensor 330 to lift up, completing a detection action. At the same time, the drive disc 313 continues to rotate, and the top plate 314 no longer supports the drive cross plate 312. The drive cross plate 312 moves downward and resets under the action of its own gravity. During the reset process of the drive cross plate 312, the push plate wheel 316 disengages from the longitudinal inclined plate 323, and the longitudinal spring 319 releases its elastic potential energy, driving the longitudinal connecting plate 322 and the longitudinal clamping plate 321 to reset, loosening the clamping of the plate; the horizontal positioning plate 324 descends with the drive cross plate 312, exits the horizontal chute 305, and releases the horizontal positioning of the plate. At this point, the detection component 3 completes a complete detection cycle and waits for the next plate to enter the detection station.
