Description

Technical Field

[0001] The utility model relates to the field of tension detection devices, and particularly relates to a tension detection device for aluminum single plates. Background Technique

[0002] An aluminum single plate refers to a building decoration material formed by chromiumizing and other treatments and then processed by fluorocarbon spraying technology. The fluorocarbon coating mainly refers to polyvinylidene fluoride resin, which is divided into three types: primer, topcoat, and varnish. In the prior art, the Chinese utility model patent with the publication number CN212432772U discloses a device for detecting the surface tension strength of an aluminum single plate. In this device, the aluminum single plate to be detected is placed on two adjusting rollers on the detection conveying surface, and the tension roller can move towards the direction close to the detection conveying surface and press on the surface of the aluminum single plate. A pressure sensor is arranged on the tension roller, and the tension strength of the surface of the aluminum single plate can be obtained, so as to detect the surface tension strength of the aluminum single plate.

[0003] However, in this document, when the tension roller presses down on the surface of the aluminum single plate, there is no fixing structure at both sides of the aluminum single plate. When the aluminum single plate bends downwards, the plate bodies at both sides are easy to separate from the adjusting rollers, resulting in detection failure. When the aluminum plate separated from the adjusting roller rebounds, it is also easy to cause safety accidents to the surrounding staff. Therefore, improvement is needed.

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figure 1 shown, a tension detection device for aluminum single plates includes a bottom plate 1, a mounting frame 2 is fixedly connected to the bottom plate 1, a cylinder 3 is fixedly connected to the mounting frame 2, an output shaft of the cylinder 3 is fixedly connected to a pressure sensor 4, the pressure sensor 4 is fixedly connected to an extrusion head 5, a test plate 8 is movably installed below the extrusion head 5, a support roller 6 is movably installed above the bottom plate 1, both ends of the support roller 6 are fixedly connected to a support frame 7, the support frame 7 is fixedly connected to the bottom plate 1, the test plate 8 is movably installed on the support roller 6, and both ends of the test plate 8 are located within a clamping sleeve 911. The extrusion head 5 is pushed downward by the output shaft of the cylinder 3, so that the extrusion head 5 squeezes the test plate 8 downward, causing the middle position of the test plate 8 to bend, and observing whether the bent test plate 8 can be completely reset, thereby detecting the tension performance of the test plate 8.

[0022] As Figures 1 - 3 shown, fixing components 9 are movably installed on both sides of the test plate 8. The fixing component 9 includes a connecting frame 901, a connecting rod 904, a bearing 905, a mounting plate 906, a second sliding rod 909, a clamping sleeve 911 and a tightening bolt 913. The connecting frame 901 is movably installed on the bottom plate 1. Both sides of the mounting plate 906 are respectively fixedly connected to the connecting rod 904. The connecting rod 904 is movably installed on the connecting frame 901 through the bearing 905. The fixing component 9 further includes a first sliding hole 902 and a first sliding rod 908. The first sliding hole 902 is opened on the connecting frame 901. The first sliding rod 908 is fixedly connected to the bottom plate 1, and the first sliding rod 908 is movably installed in the first sliding hole 902 of the connecting frame 901. The fixing component 9 further includes a roller 903. The roller 903 is fixedly connected to the lower position of the connecting frame 901. The roller 903 is movably installed on the bottom plate 1. When the middle of the test plate 8 bends, both sides of the test plate 8 tilt upward, causing the connecting frame 901 to slide on the first sliding rod 908, and the bottom surface of the connecting frame 901 slides on the bottom plate 1 through the roller 903, so that when the test plate 8 bends, the connecting frame 901 slides toward each other on the first sliding rod 908.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the second slide bar 909 is movably installed on the mounting plate 906, the sleeve 911 is fixedly connected to the upper end position of the second slide bar 909, and the fastening bolt 913 is movably installed on the sleeve 911. The fixing component 9 also includes a sleeve 907 and a limiting rod 910. The sleeve 907 is fixedly connected to the mounting plate 906. The second slide bar 909 is movably installed in the sleeve 907. The limiting rod 910 is located at the lower position of the mounting plate 906, and the two ends of the limiting rod 910 are respectively fixedly connected to the second slide bar 909. The fixing component 9 also includes a No. 1 screw hole 912, the No. 1 screw hole 912 is opened on the sleeve 911, and the fastening bolt 913 is movably installed in the No. 1 screw hole 912. The test plate When the middle part of 8 is bent, the two sides are tilted and no longer remain in a horizontal state. Therefore, the mounting plate 906 is rotated on the connecting frame 901 through the connecting rod 904 and the bearing 905 to adjust the angle of the sleeve 911. The sleeve 911 drives the second slide bar 909 to move in the sleeve 907, thereby raising it upward to a suitable height, so that the sleeve 911 can be adapted to the situation after the test plate 8 is bent, and the positions of the two sides of the test plate 8 are restricted, so that the test plate 8 is not easy to separate from the supporting roller 6, thereby ensuring that the test plate 8 is tested normally during the test process and will not be terminated due to the separation of the test plate 8. In addition, it can avoid the potential safety hazards caused by the separation of the test plate 8 from the supporting roller 6 to the surrounding personnel, thereby improving safety.

[0024] It should be noted that the present utility model is an aluminum single plate tension detection device. The test plate 8 is placed on the support roller 6, and both sides of the test plate 8 are sequentially sleeved into the jacket 911. By screwing down the fastening bolt 913, the test plate 8 is fixedly connected in the jacket 911. The air cylinder 3 pushes the extrusion head 5 to move downward, so that the extrusion head 5 squeezes the middle position of the test plate 8, causing the test plate 8 to bend. The pressure sensor 4 displays the punching pressure generated by the extrusion head 5 in real time. When the punching pressure reaches the pre-defined value, the extrusion head 5 stops squeezing the test plate 8 downward, and the extrusion head 5 resets upward. Observe whether the bent test plate 8 can be completely reset and remain parallel again. Use external tools such as a spirit level and other structures to measure the reset situation of the test plate 8, so as to detect the tension performance of the test plate 8. When the middle position of the test plate 8 bends, the connecting frame 901 slides on the first sliding rod 908 through the first sliding hole 902, and the bottom surface of the connecting frame 901 moves on the bottom plate 1 through the roller 903, so that the two connecting frames 901 move towards each other. The mounting plate 906 rotates on the connecting frame 901 through the connecting rod 904 and the bearing 905, which is convenient for the jacket 911 to adapt to the angle after the test plate 8 bends. The jacket 911 drives the second sliding rod 909 to move upward in the sliding sleeve 907 of the mounting plate 906, so as to adapt to the height lifted upward after the test plate 8 bends, so that the jacket 911 can more accurately fit the shape of the test plate 8 after bending, avoiding the test plate 8 and the support roller 6 from separating from each other during the test process, resulting in the inability to continue the detection, and also avoiding the safety accidents caused to the surrounding staff after the test plate 8 and the support roller 6 are separated.
