[0002] Aluminium alloy strip is one of the most widely used non-ferrous structural materials in the industrial field, and has been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding and chemical industry and other fields. Its raw materials mainly include pure aluminum, hot-rolled aluminum coil and aluminum alloy cast-rolled aluminum coil. By placing these raw materials in the cold rolling mill, aluminum coil of different thickness and width can be produced. Then, the aluminum coil is sent to the longitudinal cutting machine for longitudinal cutting, so as to obtain aluminum strips of different widths, which can play their respective unique roles in practical application.
[0003] The thickness detection of aluminium alloy strip involves the use of specific measuring tools and methods, such as micrometer, vernier caliper, etc., to ensure the accuracy of measurement.

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative efforts fall within the protection scope of the utility model.
[0024] In the description of the utility model, please note that the orientation terms such as "up", "down", "front", "back", "left", "right", "top", "bottom", "inner", "outer" are described based on the position relation shown in the drawing, and are aimed at simplifying the description and facilitating understanding, and not the actual orientation, structure or operation mode of the device or element, so should not be regarded as the constraint of the utility model.
[0025] Please refer to Figure 1 ,Figure 2 The aluminum alloy strip thickness detection device is similar in structure design to the device in the prior art and mainly consists of a support frame 3. The support frame 3 consists of two front and rear arranged I-shaped steel frames. This structure design makes the device have higher stability and carrying capacity. It is particularly worth noting that, in actual application, the lower sides of the two I-shaped steel frames are usually equipped with corresponding supporting legs or workbench surfaces for the purpose of simplifying display, but in the present application, these related components are omitted.
[0026] Therefore, a plurality of supporting rollers 15 are sequentially arranged on the support frame 3 from left to right, and the supporting rollers 15 are embedded into the inner sides of the two I-shaped steel frames near the end portions. The supporting rollers 15 are rotationally connected to the support frame 3 through bearings. This design enables the aluminum alloy strip 1 to be stably placed above the plurality of supporting rollers 15, thereby ensuring the stability of the aluminum alloy strip 1 during the detection process.
[0027] Further, in order to ensure the accurate position of the aluminum alloy strip 1 during the detection process, a plurality of positioning plates 2 are arranged on the upper sides of the two ends of the support frame 3, as shown in Figure 2 The vertical part of the positioning plate 2 is in L-shaped structure, and the horizontal part of the positioning plate 2 is fixed to the upper end of the support frame 3 through corresponding bolts. This structure design enables the positioning plate 2 to accurately limit the aluminum alloy strip 1, ensuring that it is accurately positioned between the positioning plates 2, thereby improving the accuracy of detection.
[0028] Compared with the prior art, the present device is specially provided with a mounting frame 6 in inverted L-shaped structure, as shown in Figure 2 The vertical section of the mounting frame 6 is detachably fixedly connected to the support frame 3 through a butterfly bolt, and the support frame 3 is also provided with a mounting hole matched with the butterfly bolt to ensure that the positioning of the mounting frame 6 accurately meets the expected requirements, thereby improving the flexibility and adaptability of the device.
[0029] It is particularly worth noting that, as shown in Figure 1 The focus of the present application is on the aluminum alloy strip 1 at the junction of the two processing steps during the conveying process. Therefore, the position set by the present application must ensure that it does not interfere with the normal processing flow and as far as possible avoids affecting other components and operating personnel. Based on this, the detachable connection design between the mounting frame 6 and the support frame 3 enables the present device to flexibly determine the layout position of the mounting frame 6 according to the actual site conditions, thereby improving the applicability of the device.
[0030] Please refer to Figure 2 、 Figure 3 、 Figure 4, specifically, the horizontal portion of the mounting frame 6 is arranged on the upper side of the aluminum alloy strip 1. A through hole is provided on the horizontal portion of the mounting frame 6, and a follower rod 19 is embedded in the through hole. The follower rod 19 tends to move downward due to its own weight, so in actual operation, the lower end of the follower rod 19 will be in contact with the mounting frame 6. At this time, any change in the thickness of the aluminum alloy strip 1 will directly affect the vertical displacement of the follower rod 19, which accurately reflects the thickness change of the surface of the aluminum alloy strip 1, thereby improving the accuracy of the detection.
[0031] Therefore, the device has a front and rear axial drawing pen 8 fixedly connected to the upper end of the follower rod 19, and a drawing paper 10 movably connected to the upper side of the horizontal portion of the mounting frame 6. By ensuring that the drawing end of the drawing pen 8 is in contact with the drawing paper 10, the height change of the follower rod 19, which is the detection data, can be accurately recorded, thereby improving the accuracy of data recording.
[0032] Further, in order to ensure that the follower rod 19 always closely adheres to the upper end surface of the aluminum alloy strip 1 and prevent the follower rod 19 from separating from the aluminum alloy strip 1 due to inertia, the device is provided with a limiting ring 17 outside the follower rod 19. The limiting ring 17 is constrained on the lower side of the horizontal portion of the mounting frame 6, and a compression spring 18 is arranged between the mounting frame 6 and the limiting ring 17. The two ends of the compression spring 18 are in contact with the follower rod 19 and the mounting frame 6, respectively, and the elastic force provided by the compression spring 18 makes the follower rod 19 have a stronger downward movement tendency, thereby effectively shortening the time of inertia effect and enhancing the stability of the detection.
[0033] In addition, the device is provided with a left and right axial rotatingly connected roller 16 at the lower end of the follower rod 19, and the lower end surface of the roller 16 is in contact with the aluminum alloy strip 1. This design can prevent sliding friction between the follower rod 19 and the aluminum alloy strip 1, avoid scratches on the surface of the aluminum alloy strip 1, ensure smooth subsequent processing, and improve the protection performance of the device.
[0034] Specifically, in order to ensure that the lines drawn on the surface of the drawing paper 10 can accurately reflect the thickness change of the aluminum alloy strip 1 at the detection position, the device is provided with a driving mechanism at one end of the drawing paper 10. The driving mechanism ensures that the drawing paper 10 moves synchronously with the aluminum alloy strip 1, guarantees the continuity and completeness of the detection data, and improves the accuracy of data recording.
[0035] Referring to Figure 1 , Figure 2 , Figure 4 , the driving mechanism includes a spring clamp 12 movably connected with the end of the drawing paper 10. This design utilizes the detachable connection between the drawing paper 10 and the spring clamp 12, which not only ensures the synchronization of movement, but also facilitates the replacement of the drawing paper 10, thereby enhancing the maintainability of the device.
[0036] Therefore, the device is provided with the suction cup 4 on the upper side of the aluminum alloy belt 1, and the synchronous movement of the suction cup 4 and the aluminum alloy belt 1 at the detection position is ensured through the negative pressure effect.
[0037] Further, the device is fixedly connected with the support 13 on the upper side of the horizontal section of the mounting frame 6, and the upper end of the support 13 is rotatably connected with the positioning shaft 9.
[0038] In addition, the support 13 is designed with the limiting hole 14 penetrating left and right, and the limiting rod 7 is inserted into the hole, which can effectively constrain the movement range of the drawing paper 10 and avoid the conflict with the support 13 when the drawing paper 10 moves downward, thereby enhancing the safety of the device.
[0039] Therefore, the limiting rod 7 and the spring clamp 12 are movably connected through the pull rope 5, and the movement range of the drawing paper 10 is further limited through the limiting rod 7, so as to prevent unnecessary contact with the support 13 and improve the safety of the device again.
[0040] Further, the drawing board 11 is fixedly connected to the upper end of the support 13, and the drawing board 11 and the drawing pen 8 are in the same vertical plane, so as to ensure the stability of the drawing pen 8 during the drawing process.
[0041] In the actual application process of the device:
[0042] Firstly, the operator fixes the mounting frame 6 on one side of the support frame 3, at this time, the roller 16 naturally falls and contacts the upper side of the aluminum alloy belt 1;
[0043] Then, the operator selects a drawing paper 10 which has not been used before and inserts it outside the positioning shaft 9;
[0044] Subsequently, the operator pulls out the outer end of the drawing paper 10, clamps the spring clamp 12 on the outer end of the drawing paper 10, and inserts the limiting rod 7 into the limiting hole 14, thereby completing the cooperation between the limiting rod 7 and the spring clamp 12.
[0045] Afterwards, the position of the drawing pen 8 is adjusted to ensure that both ends of the drawing paper 10 are clamped and fixed by the drawing pen 8 and the drawing board 11, and in the process, the suction cup 4 is adhered to the upper end of the aluminum alloy strip 1 by using the negative pressure effect.
[0046] Finally, as the aluminum alloy strip 1 continuously moves in one direction, the drawing pen 8 draws continuous and undulating lines on the drawing paper 10.
[0047] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
