[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] A gypsum board dimension online monitoring device, such as Figure 1 As shown, the monitoring device includes a conveying platform 1, which is located on the gypsum board production line and is used to receive the gypsum boards produced and to perform online dimensional inspection of the gypsum boards to control the product quality of the gypsum board production line. A top frame 2 is fixedly installed on the conveying platform 1, and a detection component 3 is fixedly installed on one side of the top frame 2. A sorting component 4 is fixedly connected to one side of the detection component 3, and the detection component 3 is located between the top frame 2 and the sorting component 4.

[0048] like Figure 2 , Figure 3As shown, a discharge rack 12 is fixedly installed at one end of the feeding platform 1, and symmetrically distributed side blocks 11 are fixedly installed at the other end. A guide rod 111 is slidably installed on the side block 11. A guide groove 112 is opened on the side of the guide rod 111. The guide groove 112 is slidably connected to the side block 11 and is used to guide the horizontal movement of the guide rod 111. An external thread 113 is opened at one end of the guide rod 111, and a guide frame is fixedly connected to the other end. A vertically arranged side roller 117 is rotatably installed inside the guide frame.

[0049] A rotating block 114 is rotatably provided on the side of the side block 11 away from the guide frame. The rotating block 114 is rotatably disposed on the outside of the side block 11 and is threadedly engaged with the external thread 113. During the continuous rotation of the rotating block 114, the guide rod 111 is controlled to move horizontally on the side block 11, so as to realize that the two side rollers 117 on the material conveying table 1 move towards or away from each other, so that the side rollers 117 move closer to or away from the side of the gypsum board.

[0050] A gear 116 is rotatably mounted on one side of the side block 11, and a motor is fixedly mounted on the other side. The output end of the motor is fixedly connected to the shaft of the gear 116 to drive the gear 116 to rotate. A gear ring 115 is fixedly mounted on the side of the rotating block 114. The gear ring 115 is located on one side of the gear 116 and meshes with the gear 116 so that the motor controls the rotation of the gear ring 115.

[0051] The conveying platform 1 is equipped with an array of conveying rollers 13. The conveying rollers 13 located below the detection component 3 and the sorting component 4 have annular grooves 14 at both ends. A rotating shaft 16 is mounted on the discharge rack 12. Symmetrically distributed side plates 15 are fixedly connected to the rotating shaft 16. Conveying rollers 13 are also rotatably mounted between the two side plates 15. A second motor 17 is fixedly mounted on one side of the discharge rack 12. The output end of the second motor 17 is fixedly connected to one end of the rotating shaft 16.

[0052] When the gypsum board is fed into the feeding table 1, the side roller 117 is used to move and guide the side of the gypsum board to ensure that the gypsum board is stably fed on the feeding roller 13. After the gypsum board is processed by the inspection piece 3 and the sorting piece 4, the gypsum board that meets the production size is fed out from the discharge rack 12 for subsequent board cutting. If the gypsum board does not meet the requirements, the side plate 15 is driven to rotate by the motor 17, and then the side plate 15 is controlled to flip upward to transport the gypsum board that does not meet the size requirements to the bottom of the discharge rack 12 for centralized collection of waste materials, which is convenient for recycling and reuse.

[0053] A hydraulic rod 19 is fixedly installed on the material conveying platform 1. The output end of the hydraulic rod 19 is fixedly connected to a support plate 18, which is used to lift up unqualified gypsum boards.

[0054] like Figure 4 , Figure 5As shown, the top frame 2 includes a top frame body 21, a slide table 1 is fixedly mounted on the top frame body 21, a slide seat 22 is slidably mounted on the slide table 1, the slide seat 22 moves horizontally under the drive of the slide table 1, the position of the slide seat 22 is adjusted, and symmetrically distributed fixing blocks 23 are fixedly mounted on the slide seat 22. The fixing blocks 23 include two connecting claws, and an annular rod 25 is rotatably mounted on the fixing blocks 23 and located between the two connecting claws. The ends of the connecting claws are provided with through grooves 24.

[0055] An arc-shaped rod 26 is slidably provided below the fixed block 23. Both ends of the arc-shaped rod 26 are rotatably mounted with limit wheels 20. The limit wheels 20 abut against the upper surface of the gypsum board, so that the gypsum board fits against the conveying roller 13 for conveying, avoiding deformation of the gypsum board surface and improving the accuracy of subsequent dimensional measurements. The arc-shaped rod 26 is provided with symmetrically distributed arc-shaped grooves 28.

[0056] A support shaft 29 is fixedly installed inside the through groove 24. The support shaft 29 is slidably connected to the arc groove 28 to support the arc rod 26. The arc groove 28 and the arc rod 26 are coaxial. An opening groove 27 is opened on the arc rod 26. The opening groove 27 is located between the two arc grooves 28. The ring rod 25 cooperates with the opening groove 27. During the rotation or swing of the arc rod 26, the ring rod 25 is movably connected to the opening groove 27, which can restrict the movement of the arc rod 26 and prevent the limiting wheel 20 on the arc rod 26 from colliding with the corner of the gypsum board and causing damage to the corner of the gypsum board.

[0057] In this embodiment, when the gypsum board moves under the limiting wheel 20, the annular rod 25 positions the opening slot 27 in the middle of the two connecting claws. At this time, the two limiting wheels 20 of the arc rod 26 are located on the same plane, and the force applied to the gypsum board surface is the same, avoiding excessive pressure from a single limiting wheel 20 and causing damage to the gypsum board surface, thus ensuring the safety of transporting the gypsum board.

[0058] like Figures 6-9 As shown, the testing component 3 includes a top plate 31, a base 32 is fixedly connected to the bottom of the top plate 31, and side frames 33 are fixedly connected to both ends of the base 32. The top of the side frames 33 is fixedly connected to the end of the top plate 31 to connect the base 32 and the top plate 31. The side frames 33 are provided with symmetrically distributed sliding grooves 34. A U-shaped frame 36 is slidably installed in the sliding grooves 34. A spring 35 is fixedly connected to one end of the U-shaped frame 36. The spring 35 is fixedly connected to the sliding grooves 34 to connect and support the U-shaped frame 36.

[0059] A laser rangefinder 30 is fixedly installed on one side of the U-shaped frame 36 to measure the distance between the U-shaped frame 36 and the side of the gypsum board. The laser rangefinder 30 is also fixedly installed on the top plate 31 and the base 32 to measure the distance between the top plate 31 and the upper surface of the gypsum board and the distance between the base 32 and the lower surface of the gypsum board, so as to comprehensively inspect the dimensions of the gypsum board and monitor the dimensions of the produced gypsum board online.

[0060] A cam 37 is rotatably mounted on the outer side of the side frame 33. A shaft 370 is fixedly connected to the cam 37. A telescopic rod 371 is slidably mounted on one end of the shaft 370. The telescopic rod 371 rotates synchronously with the shaft 370. A pin 372 is fixedly connected to one end of the telescopic rod 371. A limit plate 331 is fixedly mounted on the side frame 33. The shaft 370 is rotatably connected to the limit plate 331. The limit plate 331 has an array of pin holes 332.

[0061] The pin hole 332 is inserted into the pin rod 372 to fix the position of the cam 37. The cam 37 abuts against the lower end of the U-shaped frame 36 to support and control the up and down movement of the U-shaped frame 36. The side frame 33 has a through groove 330, which is snapped into the side plate of the conveyor table 1.

[0062] A cylinder 38 is fixedly installed on the top plate 31. Two driving rods 381 are rotatably installed at the output end of the cylinder 38. A symmetrically distributed bracket 311 is fixedly connected to the top plate 31. A driven rod 312 is rotatably installed on the bracket 311. One end of the driving rod 381 is rotatably connected to the driven rod 312. A straight groove 39 is opened at the other end of the driven rod 312.

[0063] like Figures 10-12 As shown, the sorting component 4 includes two guide rails 41. A first movable seat 42 and a second movable seat 40 are slidably mounted on the guide rails 41. A movable groove 421 is provided on the first movable seat 42. A movable plate 423 is slidably mounted on the movable groove 421. A vertical plate 424 is fixedly connected to the movable plate 423. A guide post 43 is fixedly connected to one side of the vertical plate 424. A plurality of positioning holes 431 are provided on the guide post 43.

[0064] One end of the movable plate 423 is fixedly connected to the mounting frame 44. The mounting frame 44 is fixedly provided with a slide table 441. The mounting plate 45 is slidably provided on the slide table 441. The mounting frame 44 is fixedly installed with a cylinder 442. The output end of the cylinder 442 is fixedly connected to the top of the mounting plate 45. A pneumatic clamp 46 is installed on one side of the mounting plate 45. The mounting plate 45 moves horizontally on the annular groove 14. The mounting plates 45 on both sides of the gypsum board move towards each other. The pneumatic clamp 46 clamps the side of the gypsum board. After the first movable seat 42 is clamped and fixed to the gypsum board, the first movable seat 42 moves synchronously with the gypsum board, which facilitates the cutting of the gypsum board.

[0065] A top rod 451 is slidably provided on the mounting plate 45. One end of the top rod 451 is fixedly connected to a round block 452, and the other end is fixedly provided with a spring 453. One end of the spring 453 is fixedly connected to the mounting plate 45 so that the top rod 451 fits against the side of the gypsum board and the round block 452 abuts against the side of the gypsum board, ensuring the stability of the gypsum board and facilitating the pneumatic clamp 46 to clamp the gypsum board.

[0066] A slide table 48 is fixedly connected between the two first movable seats 42. A cutter 47 is slidably installed on the slide table 48 to cut gypsum boards that do not meet the required dimensions. The system monitors the process online and rejects defective products online.

[0067] The second movable seat 40 has the same structure as the first movable seat 42. The difference is that the upright plate 424 on the second movable seat 40 is slidably connected to the guide post 43 on the corresponding position of the first movable seat 42, and the top of the upright plate 424 is fixedly provided with a cylinder 401. When the output end of the cylinder 401 is engaged with the positioning hole 431, the guide post 43 can be fixed.

[0068] A slide table 3 48 is also fixedly installed between the two second movable seats 40. A cutter 47 is installed on the slide table 3 48. The cutter 47 cuts the unqualified gypsum board products, removes the defective products in time, and automatically sorts them. The guide column 43 is slidably connected to the straight groove 39. The two guide columns 43 are controlled to move towards or away from each other by moving the driven rod 312, thereby realizing the translational movement of the mounting plate 45 towards or away from the side of the gypsum board.

[0069] A cylinder four is fixedly installed at the end of the guide rail 41 away from the detection piece 3. The cylinder four is not shown in the figure. The output end of the cylinder four faces the first moving seat 42. When the output end of the cylinder four contacts the first moving seat 42, the cylinder four pushes the first moving seat 42 to move towards the second moving seat 40 until the first moving seat 42 and the second moving seat 40 move and reset.

[0070] The working principle is as follows:

[0071] A feeding platform 1 is installed on the gypsum board production line to guide the gypsum board produced. The gypsum board then passes between two side blocks 11. Under the guidance of the side rollers 117 on the side blocks 11, the gypsum board can be controlled to be positioned between the two side rollers 117. The side rollers 117 can be adjusted to match gypsum boards of different widths.

[0072] After the gypsum board is formed, it cannot be completely attached to the conveying roller 13. At this time, the limiting wheel 20 on the arc rod 26 is attached to the surface of the gypsum board, and the gypsum board is further compacted during the conveying process, and the gypsum board is stably conveyed to the test piece 3, thereby improving the test accuracy of the gypsum board.

[0073] The gypsum board is located at the testing component 3. The laser rangefinder 30 arranged on the testing component 3 monitors the width and thickness of the gypsum board online. With the auxiliary guidance of the limiting wheel 20 and the side roller 117, the accuracy of the gypsum board size measurement is ensured.

[0074] When the measured dimensions of the gypsum board are not up to standard, the output end of cylinder 38 controls the movement of the drive rod 381. The driven rod 312 moves with the drive rod 381 and drives the first moving seat 42 and the second moving seat 40 to approach the gypsum board. When the gypsum board is not up to standard, it reaches the pneumatic clamp 46 of the first moving seat 42. The pneumatic clamp 46 clamps and fixes the gypsum board. Then, if the gypsum board continues to be conveyed, the gypsum board will drive the first moving seat 42 to move horizontally.

[0075] After the subsequent gypsum board dimensions are verified to be acceptable, the pneumatic clamp 46 on the second movable seat 40 clamps the gypsum board, and the two cutters 47 cut the unacceptable sections of the gypsum board. Then, the acceptable gypsum board is conveyed out from the top of the discharge rack 12, and the unacceptable gypsum board is flipped upward by the side plate 15, and the support plate 18 lifts one end of the gypsum board, so that the gypsum board is conveyed downward by the discharge rack 12, thereby achieving material separation.

[0076] In this embodiment, the size laser measurement and quality control are completed during the production and transportation process, reducing subsequent quality inspection procedures and improving production efficiency. Furthermore, the laser rangefinder 30 is used to measure the size of the gypsum board online with high accuracy and simple measurement operation.
