[0002] The design of the whole-board tensile strength testing device for new material thermal insulation decorative panels is mainly aimed at testing the tensile properties of thermal insulation decorative panels by simulating the actual use environment.

[0003] The patent with patent announcement number CN221174176U relates to a U-shaped container bag tensile strength testing device, including a workbench, a clamping mechanism, a mounting plate and a force strength tester. The clamping mechanism is arranged at the upper end of the workbench, the mounting plate is fixedly installed on the upper end surface of the workbench, the force strength tester is installed at the upper end of the mounting plate, and a disassembly and assembly mechanism is connected between the mounting plate and the force strength tester; the disassembly and assembly mechanism includes a concave groove, a plug-in groove, and a plug-in block. This patent integrates the force strength tester and the clamping mechanism into an integrated design, and then hooks one end of the U-shaped container bag on the force strength tester, and clamps the other end through the clamping mechanism and automatically moves the clamping mechanism to quickly obtain the test results; during the period, the disassembly and assembly mechanism is combined to allow the force strength tester to be conveniently disassembled and assembled, thereby facilitating the replacement of different models, thereby improving the detection efficiency and convenience of use.

[0004] In the above patent, the test results can be quickly obtained by clamping and automatically moving the clamping mechanism; during the process, the disassembly and assembly mechanism is combined to allow the force strength tester to be conveniently disassembled and assembled, thereby facilitating the replacement of different models, thereby improving the detection efficiency and ease of use. However, due to the design of some decorative panels, the surface is relatively smooth, which makes it easy for the decorative panels to slip out during testing, resulting in the inability to test the tensile strength of the decorative panels. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a device for detecting the tensile strength of a whole-plate thermal insulation decorative panel made of a new material, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a device for detecting the tensile strength of a whole plate of a new material thermal insulation decorative plate, comprising a flat plate, a guide rod being fixedly mounted on the top of the flat plate; An operating table is slidably mounted on the top of the flat plate. The operating table slides through the circumferential surface of the guide rod. Two sets of operating tables are provided. A driving device is provided inside one set of operating tables. The driving device is used to drive one of the operating tables to slide on the top of the flat plate. The operating table is used to position and detect the decorative panel. A hydraulic rod is fixedly installed on the surface of the operating table, and a lower pressure plate is fixedly installed on the top of the output end of the hydraulic rod; A positioning rod, which is fixedly mounted on the inner wall of the lower pressing plate and is used to determine the position of the decorative panel and fix it. When the fixed end of the positioning rod contacts the decorative panel, the output end of the hydraulic rod stops moving, so that the fixed end of the positioning rod contacts the decorative panel and positions the decorative panel; A grinding plate is slidably installed on the top of the operating table, and a penetrating rod is slidably penetrated through the surface of the operating table. One end of the penetrating rod is fixedly connected to the grinding plate, and a roller is rotatably installed on the other end of the penetrating rod. A curved rod is fixedly installed on the bottom of the lower pressure plate. The grinding plate will move back and forth and slightly grind the bottom of the decorative plate, so that when the decorative plate is initially positioned at the top, the device will slightly grind the bottom of the decorative plate.

[0007] According to the above technical solution, a fixed vertical rod is slidably installed at the bottom of the arc rod, and the fixed vertical rod is fixedly installed on the surface of the operating table. A positioning device for limiting the decorative panel and a protective device for protecting the entire device are provided inside the operating table.

[0008] According to the above technical solution, a No. 1 spring is provided between the grinding plate and the operating table, and the arc rod is in contact with the roller. When the arc rod is no longer in contact with the roller, the No. 1 spring drives the grinding plate to reset.

[0009] The cam is fixedly mounted on the bottom of the inner wall of the operating table, and a square groove is provided inside the operating table. The sliding block is slidably mounted on the inner wall of the hollow box, and the arc block is fixedly mounted on the bottom of the sliding block. The penetrating sliding block slides through the inner and outer walls of the hollow box and the operating table. The sliding block contacts the bottom of the decorative plate when it moves, and the decorative plate is limited by the lower pressure plate through the contact of the sliding block with the decorative plate at the bottom. The circular rod is fixedly mounted on the inner wall of the hollow box, and the telescopic rod is fixedly mounted on the surface of the sliding block. The upper pressure plate is slidably mounted on the top of the free end of the telescopic rod. The upper pressure plate moves away from each other while moving toward the top, so that the squeezed part of the decorative plate that is positioned is driven to extend to both sides by the upper pressure plate.

[0010] According to the above technical solution, the through slide rod is in contact with the arc block, and a No. 2 spring is provided between the through slide rod and the operating table. The No. 2 spring drives the through slide rod to reset when the arc rod is no longer in contact with the through slide rod.

[0011] According to the above technical solution, a No. 3 spring is provided between the sliding block and the hollow box, the upper pressure plate contacts the circular rod, and the sliding block is driven to reset by the No. 3 spring.

[0012] According to the above technical solution, the protective device includes: a guide wheel, a connecting cross bar, a limit rod, a fixing part, a rotating shaft and a rotating rod, the guide wheel is rotatably installed on the inner wall of the operating table, the connecting cross bar is fixedly installed on the surface of the sliding bar, the limit rod is fixedly installed on the top of the connecting cross bar, the fixing part is fixedly installed on the top of the limit rod, the rotating shaft is fixedly installed on the side of the guide wheel close to the limit rod, and the rotating rod is rotatably installed on the circumferential surface of the rotating shaft. The tension of the decorative panel is released at the moment of breaking, and the operating table is driven to move by the driving device, so that the inertia of the decorative panel is large when it breaks. When the guide wheel rotates rapidly, it generates sufficient centrifugal force to drive the rotating rod to rotate in the direction of the limit rod. The rotating rod is blocked by the limit rod, so that the rotating rod can no longer continue to rotate, so that the guide wheel is limited at the moment of the decorative panel breaking.

[0013] According to the above technical solution, a torsion spring is provided between the rotating rod and the rotating shaft, and the limiting rod is in contact with the rotating rod. When the rotating shaft stops rotating, the torsion spring drives the rotating rod to reset.

[0014] The present invention provides a device for testing the tensile strength of a whole-plate thermal insulation decorative panel made of a new material. It has the following beneficial effects: (1) This invention stops the output end of the hydraulic rod from moving when the fixed end of the positioning rod contacts the decorative panel, so that the fixed end of the positioning rod contacts the decorative panel and positions the decorative panel. This allows the device to initially position and limit the decorative panel before testing, ensuring that the decorative panel will not be displaced during subsequent operations, facilitating subsequent operations and improving the comfort of using the device. The grinding plate moves back and forth and slightly grinds the bottom of the decorative panel, so that when the decorative panel is initially positioned at the top, the device slightly grinds the bottom of the decorative panel to prevent the decorative panel from being separated from the decorative panel during stretching due to its own smooth surface. This ensures that the device can complete testing when testing decorative panels made of various materials, thereby improving the reliability of the device.

[0015] (2) In this invention, the sliding block moves to contact the bottom of the decorative panel, and the sliding block contacts the decorative panel at the bottom and cooperates with the lower pressure plate to limit the decorative panel, so that the top and bottom of the decorative panel are limited, ensuring that the fracture of the decorative panel is close to the center during testing, ensuring the accuracy of measurement. The upper pressure plate moves away from each other while moving toward the top, so that the squeezed part of the decorative panel is driven by the upper pressure plate to stretch to both sides, preventing the squeezed part of the decorative panel from causing deformation and causing the measured data, thereby further ensuring the reliability of the measurement data of the device.

[0016] (3) This invention releases the tension of the decorative panel at the moment of its breaking, and the driving device drives the operating table to move, so that the decorative panel has a large inertia when it breaks. When the guide wheel rotates rapidly, it generates sufficient centrifugal force to drive the rotating rod to rotate in the direction of the limit rod. The rotating rod is blocked by the limit rod, so that the rotating rod can no longer rotate. At the moment of the decorative panel breaking, the guide wheel is limited, preventing the excessive inertia from causing damage to part of the device, thereby improving the service life of the device.

The operating platform 3 is used to position and detect the decorative panel. A hydraulic rod 4 is fixedly mounted on the surface of the operating table 3, and a lower pressing plate 5 is fixedly mounted on the top of the output end of the hydraulic rod 4; Positioning rod 6, the positioning rod 6 is fixedly installed on the inner wall of the lower pressing plate 5, and is used to determine the position of the decorative plate and fix it, so that the device can initially position and limit the decorative plate before testing, ensuring that the decorative plate will not be displaced during subsequent operations, facilitating subsequent operations and improving the comfort of using the device; A grinding plate 7 is slidably installed on the top of the operating table 3, and a penetrating rod 8 is slidably penetrated on the surface of the operating table 3. One end of the penetrating rod 8 is fixedly connected to the grinding plate 7, and a roller 9 is rotatably installed on the other end of the penetrating rod 8.

The interior of the operating table 3 is provided with a positioning device for limiting the decorative panel and a protective device for protecting the entire device.

[0022] A No. 1 spring 12 is provided between the grinding plate 7 and the operating table 3 , and the cambered rod 11 is in contact with the roller 9 . The No. 1 spring 12 drives the grinding plate 7 to reset when the cambered rod 11 is no longer in contact with the roller 9 .

[0023] When this embodiment is working: the decorative panel to be tested is placed on the top of the operating table 3, and then the hydraulic rod 4 is started.

[0027] The protective device includes: a guide wheel 141, a connecting cross bar 142, a limiting rod 143, a fixing member 144, a rotating shaft 145 and a rotating rod 146. The guide wheel 141 is rotatably mounted on the inner wall of the operating table 3, the connecting cross bar 142 is fixedly mounted on the surface of the sliding rod 134, the limiting rod 143 is fixedly mounted on the top of the connecting cross bar 142, the fixing member 144 is fixedly mounted on the top of the limiting rod 143, the rotating shaft 145 is fixedly mounted on a side of the guide wheel 141 close to the limiting rod 143, and the rotating rod 146 is rotatably mounted on the circumferential surface of the rotating shaft 145, so that at the moment the decorative panel breaks, the guide wheel 141 is limited to prevent damage to part of the device due to excessive inertia, thereby improving the service life of the device.

[0028] A torsion spring is provided between the rotating rod 146 and the rotating shaft 145 , and the limiting rod 143 is in contact with the rotating rod 146 . The torsion spring drives the rotating rod 146 to reset when the rotating shaft 145 stops rotating.

[0029] When this embodiment is working, the cambered rod 11 moves toward the bottom and contacts the through-slide rod 134. The movement of the cambered rod 11 drives the through-slide rod 134 to move toward the inside of the bottom operating table 3. The movement of the through-slide rod 134 contacts the arc block 133. The movement of the through-slide rod 134 drives the arc block 133 to move toward the top. The movement of the arc block 133 drives the sliding block 132 to move toward the top.

It is in a position close to the center to ensure the accuracy of measurement. The sliding block 132 moves toward the bottom, driving the telescopic rod 137 to move toward the top. The movement of the telescopic rod 137 drives the upper pressure plate 138 to move toward the top. The movement of the upper pressure plate 138 will contact the circular rod 136. The upper pressure plate 138 is blocked by the circular rod 136, so that the upper pressure plate 138 moves away from each other while moving toward the top, so that the decorative plate is driven by the upper pressure plate 138 to stretch to both sides when it is squeezed by the positioning, preventing the positioning part from being squeezed and causing part of the decorative plate to be deformed, resulting in the measured data, further ensuring the reliability of the measurement data of the device.

[0030] The movement of the sliding rod 134 drives the connecting cross bar 142 to move in the direction of the guide wheel 141, and the movement of the connecting cross bar 142 drives the limiting rod 143 to move in the direction of the guide wheel 141. After the decorative panel breaks, the driving device continues to drive the operating platform 3 to move after the device completes the test, and the movement of the operating platform 3 drives the guide wheel 141 to rotate. Since the tension of the decorative panel is released at the moment of breaking, and the driving device drives the operating platform 3 to move, the inertia of the decorative panel is large when it breaks, and when the guide wheel 141 rotates rapidly, it generates sufficient centrifugal force to drive the rotating rod 146 to rotate in the direction of the limiting rod 143. The rotating rod 146 is blocked by the limiting rod 143, so that the rotating rod 146 can no longer continue to rotate, so that at the moment the decorative panel breaks, the guide wheel 141 is limited to prevent excessive inertia from causing damage to part of the device, thereby improving the service life of the device.
