[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0053] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0054] See also Figure 1 and Figure 2 The present invention provides a technical solution: a thickness detection device for building material detection, comprising a base 1, a conveying mechanism 2 for transporting building materials is arranged on the base 1, a bracket 5 is arranged above the base 1 and the conveying mechanism 2, the bracket 5 comprises two symmetrically arranged fixing plates 51, the tops of the two fixing plates 51 are commonly connected with a top plate 52, and a controller 53 is installed on the upper surface of the top plate 52;

[0055] A jumping mechanism 7 is arranged between the top plate 52 and the base 1, an auxiliary mechanism 6 is arranged on one side of the jumping mechanism 7, and an extension plate 8 is connected to the other side of the jumping mechanism 7 through a partition 77. A distance measuring component 78 is arranged on the partition 77, and a coating roller 9 is installed below the extension plate 8 through an adjusting component.

[0056] In the process of testing building materials, the plate to be tested is placed on the conveying mechanism 2 from one end of the base 1, and the conveying mechanism 2 will move the plate to the bracket 5 at the other end. When the plate moves to the bottom of the bracket 5, the roller 71 located under the jumping mechanism 7 contacts the plate, thereby driving the resistance value of the potentiometer 781 in the distance measuring component 78 to change. The thickness of the plate to be tested is calculated based on the functional relationship between the displacement and the resistance change.

[0057] The controller 53 is electrically connected to the first motor 24 and the second motor 63 respectively, and the telescopic end position of the hydraulic cylinder 76 can be adjusted by the controller 53 . In addition, the controller 53 can transmit a constant power supply voltage to the potentiometer 781 .

[0058] In this embodiment: refer to Figure 3 The base 1 includes two horizontal bars 11 arranged in opposite positions, and the two ends of the two horizontal bars 11 are respectively fixedly connected with vertical bars 12, and the conveying mechanism 2 is arranged in a frame composed of the two horizontal bars 11 and the two vertical bars 12;

[0059] A plurality of supporting legs 13 are respectively arranged at the bottom of the two vertical rods 12, and an adjusting foot 14 is installed at the bottom of each of the supporting legs 13;

[0060] Guide wheels 4 are respectively arranged on the upper surfaces of the two cross bars 11 .

[0061] It should be noted that the fixing rod at the top of the adjusting foot 14 is provided with an external thread, and matches the internal thread groove opened at the bottom of the supporting leg 13, so that the adjusting foot 14 can be directly screwed to adjust the height of the adjusting foot 14 at different positions to ensure that the base 1 remains level during the use of the device.

[0062] Furthermore, by arranging guide wheels 4 on the cross bars 11 on both sides of the base 1, in the process of conveying the plates to be inspected, plates that are smaller than the conveying interval of the base 1 may not be processed. When the width of the plates is similar to the width of the conveying mechanism 2, if the plates are tilted and offset during the conveying process, the edges of the plates will contact the guide wheels 4, and the guide wheels 4 will rotate and limit the plates to a certain extent, thereby preventing the plates from being unable to pass through the subsequent jumping mechanism 7 and the coating roller 9 smoothly due to excessive deviation angles during the conveying process.

[0063] In this embodiment: refer to Figure 3 The conveying mechanism 2 includes a plurality of conveyor belts 21 arranged at equal intervals, the plurality of conveyor belts 21 are arranged parallel to the crossbar 11, and both ends of the plurality of conveyor belts 21 are respectively penetrated and connected with a synchronous shaft 22;

[0064] The two ends of the synchronous shaft 22 on one side are respectively connected to the bearing seat 23, and the bottom of the bearing seat 23 is fixedly connected to the upper surface of the cross bar 11. The two ends of the synchronous shaft 22 on the other side are respectively connected to the bearing seat 23 and the first motor 24, and the first motor 24 is arranged in the installation groove opened on the cross bar 11.

[0065] Specifically, when the building board to be inspected is transported by the conveying mechanism 2, the first motor 24 can be started first. The output shaft of the first motor 24 will drive the synchronous shaft 22 on one side to rotate synchronously, and cooperate with the transmission connection of the synchronous shaft 22 on the other side. Multiple conveyor belts 21 can be operated at the same time, so that the board placed on the conveyor belt 21 is transported to the other end of the base 1 for thickness detection.

[0066] In this embodiment: refer to Figure 3 A connection mechanism 3 is provided on one side of the conveying mechanism 2, and the connection mechanism 3 includes a transmission rod 31, and a plurality of rotating wheels 32 are equidistantly provided on the transmission rod 31, and the plurality of rotating wheels 32 are rotatably connected to the transmission rod 31, and the top of the rotating wheel 32 is arranged on the same horizontal line as the top of the conveyor belt 21;

[0067] Brackets 33 are respectively installed at both ends of the transmission rod 31 , and the bottom of the bracket 33 is fixedly connected to the upper surface of the vertical rod 12 .

[0068] In order to improve the practicality and functionality of the device and facilitate the conveying mechanism 2 to convey the building board, when the board is placed on the conveyor belt 21, the lower surface of the board first contacts the rotating wheel 32. When detecting longer boards, the board is supported from the edge of the base 1 to avoid damage caused by friction between the lower surface of the board and the edge of the base 1.

[0069] In this embodiment: refer to Figure 4The auxiliary mechanism 6 includes a brush roller 61 which is inclined relative to the vertical rod 12, one end of the brush roller 61 is rotatably connected to a connecting rod 62, the top of the connecting rod 62 is fixedly connected to the top plate 52, and the other end of the brush roller 61 is connected to a second motor 63 through a coupling, and the second motor 63 is connected to the side wall of the fixed plate 51 through a mounting plate 64.

[0070] In the optimization and improvement of the above scheme, when the building board is transported to the bracket 5, the second motor 63 is started, and the output shaft of the second motor 63 will drive the brush roller 61 to rotate synchronously. The bristles arranged on the outer wall of the brush roller 61 can be used to sweep away dust and debris accumulated on the surface of the board, thereby avoiding affecting the detection results during subsequent measurements. Furthermore, by setting the brush rollers 61 on both sides to different inclination angles, the swept impurities can be directly pushed to the sides of the mixed vegetables during the process of sweeping away dust and debris, and finally fall from the edge of the board, thereby reducing the environmental pollution caused to the working area and facilitating the subsequent unified collection and cleaning of dust and debris.

[0071] In this embodiment: refer to Figure 5 , Figure 6 and Figure 7 The jumping mechanism 7 includes a roller 71, and both ends of the roller 71 are rotatably connected to an assembly seat 711, and the upper ends of the two assembly seats 711 are commonly connected to a hanging plate 712, and the side wall of the hanging plate 712 is fixedly connected to a guard plate 72, and the guard plate 72 is an arc-shaped plate;

[0072] Two springs 73 are symmetrically arranged on the top of the hanging plate 712, and the tops of the two springs 73 are commonly connected to a positioning plate 75;

[0073] A movable rod 74 is disposed between the two springs 73 , and the bottom of the movable rod 74 is fixedly connected to the hanging plate 712 , and the top of the movable rod 74 is slidably connected to the positioning plate 75 .

[0074] The plate moves smoothly on the conveyor belt 21 when it is transported to the bottom of the jumping mechanism 7. The guard plate 72 is arranged in cooperation. Since the guard plate 72 is an arc-shaped plate, it can slide when the guard plate 72 contacts the plate, so that the plate is guided to the bottom of the roller 71, and the outer wall of the roller 71 is protected to a certain extent, so as to avoid damage to the surface of the roller 71 caused by the friction generated when the roller 71 contacts the edge of the plate, thereby reducing the impact on the subsequent measurement accuracy. When the roller 71 moves to the upper surface of the plate, the spring 73 contracts, and the stored elastic potential energy can push the roller 71 to contact the plate closely. At the same time, the lifting plate 712 above the roller 71 drives the movable rod 74 to move synchronously. Furthermore, the through groove on the positioning plate 75 corresponding to the movable rod 74 can limit the movable rod 74 to ensure that the movable rod 74 always maintains vertical movement.

[0075] In this embodiment: refer to Figure 7 Two hydraulic cylinders 76 are symmetrically arranged above the positioning plate 75 , and the bases of the two hydraulic cylinders 76 are connected to the lower surface of the top plate 52 , and the telescopic ends of the two hydraulic cylinders 76 are fixedly connected to the upper surface of the positioning plate 75 .

[0076] In order to achieve accurate measurement of the thickness of the plate, the telescopic end of the hydraulic cylinder 76 can drive the positioning plate 75 to move downward. Since the roller 71 and the conveyor belt 21 are aligned, before the detection, the roller 71 is made to contact with the adjacent conveyor belts 21 respectively. At this time, the initial detection position can be calibrated to facilitate the subsequent calculation of the displacement of the roller 71.

[0077] In this embodiment: refer to Figure 8 and Fig. 9 The distance measuring component 78 includes a potentiometer 781 which is arranged on the partition 77, a resistor 782 is arranged on the potentiometer 781, a brush 783 is slidably arranged on the resistor 782, an insulating frame 784 is fixedly connected to the brush 783, and the end of the insulating frame 784 away from the brush 783 is fixedly connected to the top of the movable rod 74.

[0078] When in use, the top of the movable rod 74 drives the insulating frame 784 to move synchronously, thereby driving the insulating frame 784 to move away from the brush 783 on one side of the movable rod 74, so that the position of the brush 783 on the resistor 782 changes, thereby changing the resistance value between the two ends of the resistor 782, and the voltage drawn from the brush 783 and one end of the potentiometer 781 will also change accordingly. By measuring the difference before and after the output voltage and converting it through a functional relationship, the displacement of the top of the movable rod 74 can be obtained, thereby obtaining the thickness of the building board.

[0079] In this embodiment: refer to Fig.10 The adjustment assembly includes two threaded sleeves 81, and the two threaded sleeves 81 are arranged at both ends of the extension plate 8, and the two threaded sleeves 81 are respectively threadedly connected with threaded rods 82, and the tops of the two threaded rods 82 are fixedly connected with knobs 83, and the bottoms of the two threaded rods 82 are respectively rotatably connected with supports 84;

[0080] The coating roller 9 is disposed between the two supports 84, and both ends of the coating roller 9 are rotatably connected to the corresponding side walls of the supports 84;

[0081] The outer wall of the coating roller 9 is covered with a protective pad 91 . A plurality of grooves 92 are circumferentially formed on the outer surface of the protective pad 91 . The plurality of grooves 92 spirally extend from one end of the protective pad 91 to the other end of the protective pad 91 .

[0082] Specifically, after obtaining the thickness of the plate, the height of the coating roller 9 can be set at the elevation position, and the threaded rod 82 can be driven to rotate by respectively turning the knobs 83 on both sides. Under the limiting action of the threaded sleeve 81, the threaded rod 82 will move along the set direction, thereby adjusting the height of the two ends of the coating roller 9, so that the protective pad 91 coated on the coating roller 9 is in contact with the surface of the plate. While the plate is continuously conveyed, the coating roller 9 keeps rotating, so that the paint attached to the protective pad 91 is smeared on the surface of the plate. Relying on the intuitive display of the paint, the depressions on the plate can be marked, which is convenient for taking targeted measures to deal with the defects of the plate.

[0083] In addition, during the process of the coating roller 9 contacting and rotating with the plate, the protruding part of the plate can pass smoothly by relying on the deformation of the pad 91 itself. Furthermore, by opening a plurality of spiral grooves 92 circumferentially on the pad 91, relying on the concentration difference of the pigment in the grooves 92, the attached pigment can be guided to avoid water explosion that affects the pigment display effect.

[0084] In this embodiment: refer to Fig.11 A liquid storage tank 85 is fixedly mounted on the upper surface of the extension plate 8, and a box door is mounted on the top of the liquid storage tank 85 via a hinge. A hose 851 communicating with the interior of the liquid storage tank 85 is disposed at the bottom of the liquid storage tank 85. The hose 851 is embedded in the extension plate 8, and the hose 851 is arranged parallel to the axis of the coating roller 9.

[0085] The hose 851 is connected to a plurality of nozzles 852 , and the plurality of nozzles 852 are all disposed directly above the protective pad 91 , and the plurality of nozzles 852 are arranged at equal distances.

[0086] During use, an appropriate amount of aqueous pigment solution can be added to the liquid storage tank 85 for marking and to facilitate subsequent cleaning. During the coating process, the release of toxic gases to pollute the working area is avoided, and the marking layer formed after drying is relatively thin, which will not interfere with the detection of the thickness and flatness of the board surface. Furthermore, clean water can be directly added to the liquid storage tank 85. For building materials to be tested that have strong water absorption or require surface aesthetics, clean water can be applied to the surface of the building materials through the coating roller 9, which can display the markings more clearly, and no separate cleaning is required later, so as to avoid the incomplete cleaning of the pigment due to the water absorption characteristics of the material itself, affecting its use. Relying on the connected hose 851, the pigment solution in the liquid storage tank 85 can be sprayed out from the nozzle 852, and finally flow to the coating roller 9 below the nozzle 852, to ensure a uniform supply of pigment.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
