DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0021] As Figures 1 to 9As shown, a kind of visual detection device for conveying belt anti-tearing, including visual detector body 1, transparent shield 2 connected on visual detector body 1 and control center 18 connected on visual detector body 1, U-shaped support 3 is fixed on visual detector body 1, guide groove 8 is set in U-shaped support 3, driving element is installed on U-shaped support 3, rectangular block 6 is slidably connected in guide groove 8, rotation slot 11 is set in rectangular block 6, rotation shaft 13 is rotatably connected in rotation slot 11, input end of rotation shaft 13 is installed with servo motor 12, a plurality of sliding grooves 14 are set on the outer wall of rotation shaft 13, connecting block 16 is slidably connected in sliding groove 14, wiping element 17 is installed on connecting block 16.

[0022] As Figure 1 shown, the visual detection device for conveying belt anti-tearing in the utility model is similar in structure to the existing visual tearing and damage detection device, and a visual tearing and damage detection device is disclosed in the patent with publication number CN219891116U.The main improvement of the utility model is that new wiping element can be switched to ensure cleaning efficiency after the wiping element accumulates dirt, as Figures 1 to 8 shown, the visual detection device for conveying belt anti-tearing in the utility model is similar in structure to the existing visual tearing and damage detection device, and a visual tearing and damage detection device is disclosed in the patent with publication number CN219891116U.The main improvement of the utility model is that new wiping element can be switched to ensure cleaning efficiency after the wiping element accumulates dirt, as

[0023] As Figure 1 and Figure 2 shown, driving element includes motor 4 and threaded rod 5, motor 4 is fixedly connected on U-shaped support 3, the output end of motor 4 is connected with the input end of threaded rod 5 through coupling, rectangular block 6 moves by being connected on threaded rod 5 by screw thread.

[0024] Specifically, when the device needs to be cleaned, the user can send an instruction to the control center 18 through the computer terminal, and the control center 18 will control the motor 4 to perform a forward and reverse operation, thereby driving the threaded rod 5 to rotate smoothly. With the rotation of the threaded rod 5, the wiping member 17 is effectively driven to move linearly in the left-right direction. This movement trajectory ensures that the wiping member 17 can thoroughly clean the surface of the transparent protective cover 2, thereby maintaining its cleanliness and providing a clear and accurate field of view for visual inspection. It is worth noting that the control center 18, the motor 4 and the servo motor 12 are all existing technologies, so they will not be described in detail here.

[0025] As shown in Figures 1-9 The outer wall of the rectangular block 6 is provided with a protective tube 7, and the lower end of the protective tube 7 is provided with a through hole 9 communicating with the internal space. One section of the inner wall of the through hole 9 is fixedly connected with an arc-shaped guide plate 10. The sliding groove 14 is fixedly connected with a reset spring 15, and the other end of the reset spring 15 is fixedly connected with the connecting block 16.

[0026] Specifically, when the wiping member 17 moves to the position of the through hole 9, it will be quickly and smoothly ejected from the protective tube 7 under the action of the reaction force provided by the return spring 15. At this time, the clean and ready wiping member 17 will replace the previous contaminated wiping member 17 and continue to clean the transparent protective cover 2 efficiently. When the contaminated wiping member 17 continues to rotate and reaches the area of the arc-shaped guide plate 10, it will be gradually compressed and returned to the inside of the protective tube 7 under the extrusion of the arc-shaped guide plate 10. This process ensures the smooth replacement of the wiping member 17 and the effective recovery of the contaminated wiping member 17, thereby ensuring the continuity and efficiency of the entire cleaning process. In addition, the design of the return spring 15 plays a great role in the replacement and recovery process of the wiping member 17. When switching to a new wiping member 17, it not only enables it to be easily and quickly ejected to clean the transparent protective cover 2 efficiently, but also smoothly compresses the wiping member 17 back into the protective tube 7 with the assistance of the arc-shaped guide plate 10 when recovering the contaminated wiping member 17. This design not only improves the smoothness of the replacement of the wiping member 17, but also effectively avoids damage or scratches to the transparent protective cover 2 caused by the wiping member 17 during cleaning, thereby ensuring the quality and safety of the cleaning work. In addition, when the return spring 15 is fully extended, the top end of the connecting block 16 remains in the internal position of the sliding groove 14. At the same time, the tapered design of the arc-shaped guide plate guides the contaminated wiping member to smoothly return to the protective tube, avoiding interference with the standby wiping member. It is worth noting that the rectangular block 6 and the protective tube 7, as well as the wiping member 17 and the connecting block 16, are detachably fixed by fastening bolts. The fastening bolts are common fastening structures, so they are not shown in the figure. In addition, multiple wiping members 17 are evenly distributed, with the following distribution rule: whenever a contaminated wiping member 17 is completely recovered into the protective tube 7, the next standby wiping member 17 can be timely ejected from the through hole 9 to seamlessly connect the cleaning work. This ingenious layout not only improves the efficiency of the replacement of the wiping member 17, but also ensures the continuity and stability of the entire cleaning process.

[0027] As shown in Figure 3 , Figure 5 , Figure 6 , Figure 8 and Figure 9 , the circular arc trajectory of the arc-shaped guide plate 10 is larger than the movement trajectory of the wiping member 17, and its end abuts against the inner wall of the protective tube 7. The circular arc trajectory of the arc-shaped guide plate 10 gradually decreases from large to small until it is consistent with the circumference of the inner wall of the protective tube 7, which can effectively guide the wiping member 17 to be smoothly and orderly returned to the inside of the protective tube 7.

[0028] As shown in Figure 5 , Figure 8 and Figure 9As shown in the drawings, the wiping member 17 can be one of a wiping sponge, a microfiber cloth, a non-woven fabric, etc., all of which have excellent water absorption and dust absorption capabilities, and can effectively remove stains, dust and residues on the transparent protective cover 2, ensuring the clarity and accuracy of the visual detector. Secondly, they will not scratch or damage the surface of the transparent protective cover 2, helping to prolong its service life.

[0029] As shown in the drawings, Figure 1 , Figure 2 , Figure 5 , Figure 8 and Figure 9 , the contact surface of the wiping member 17 with the transparent protective cover 2 is provided as a circular arc surface, which can improve the wiping effect, reduce friction and wear, enhance adaptability and avoid scratching the cover.

[0030] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement for part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model shall be included in the protection scope of the utility model.
