Description

Technical Field

[0001] This utility model relates to the field of aluminum plate thickness detection technology, and in particular to an automatic detection mechanism for the output thickness of a cold rolling mill. Background Technology

[0002] Cold rolling mills are essential equipment widely used in the metal processing industry, playing a crucial role, especially in the processing of materials such as copper busbars and steel plates. Through rolling processes, cold rolling mills transform raw materials into the required thickness to meet subsequent processing or usage needs. Traditional cold rolling mills typically rely on manual measurement of the output thickness using tools such as vernier calipers. This measurement method is not only time-consuming and labor-intensive but also susceptible to human error, leading to significant measurement errors and failing to meet the production requirements of high-precision products. Furthermore, because traditional cold rolling mills lack real-time thickness monitoring capabilities, operators cannot promptly understand thickness changes during the rolling process, making timely adjustments to rolling parameters difficult and impacting the stability and consistency of product quality. Utility Model Content

[0003] In view of the above situation and to overcome the defects of the prior art, this utility model provides an automatic detection mechanism for the output thickness of a cold rolling mill. This design effectively solves the problem that existing cold rolling mills do not have a thickness detection function during operation, requiring manual thickness testing and failing to provide real-time feedback on the thickness of the material plate, thus affecting the stability and consistency of product quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see the appendix Figure 1-6 This embodiment provides an automatic detection mechanism for the output thickness of a cold rolling mill: it includes a detection platform 1, a support rod 2 on the detection platform 1, a material conveying roller 3 on the side of the support rod 2, the material conveying roller 3 being rotatably connected to the detection platform 1, a detection rod 4 on the side of the material conveying roller 3, a rotating shaft 5 fixedly connected to the detection rod 4, detection feedback mechanisms 6 at both ends of the rotating shaft 5, and a pressure roller 7 on the side of the detection rod 4, the pressure roller 7 being mounted on the detection platform 1.

[0024] Support rod 2 is located on the left side of inspection table 1. Along the forward direction of the material plate, the material plate sequentially contacts support rod 2, material plate conveying roller 3, inspection rod 4, and pressure roller 7 on inspection table 1. The height of support rod 2 is higher than the height of material plate conveying roller 3. The conveyed material plate rests on top of support rod 2. Material plate conveying roller 3 is located below and to the right of support rod 2. Material plate conveying roller 3 exerts a rightward force on the material plate through rotation. Under the action of material plate conveying roller 3, the material plate continuously moves to the right on inspection table 1. Inspection rod 4 is located to the right of material plate conveying roller 3 and below the material plate. The inspection table 1 below inspection rod 4 is a horizontal plane. The material plate is located between inspection rod 4 and... Between the detection platforms 1, the detection rod 4 is rotatably connected to the detection platform 1 via the rotating shaft 5. When the thickness of the material plate changes, the angle between the detection plate and the detection platform 1 will also change accordingly. The change in the angle of the detection plate will drive the rotating shaft 5 to make a certain angle change. The detection feedback mechanism 6 on both sides of the rotating shaft 5 detects and provides feedback on the rotation of the rotating shaft 5. In production, the change in the thickness of the material plate is known through the detection feedback mechanism 6. The pressure roller 7 is located on the right side of the detection rod 4. The pressure roller 7 can ensure the flat contact between the material plate and the detection platform 1, avoid gaps between the material plate and the detection platform 1, and ensure the accuracy of the detection rod 4 in detecting the thickness of the material plate.

[0025] The detection feedback mechanism 6 includes an indicator disk 601 and an indicator block 602. The indicator disk 601 is mounted on one end of the rotating shaft 5 and is rotatably connected to the detection platform 1. The other end of the rotating shaft 5 is fixedly connected to a first connecting rod 603. The first connecting rod 603 is hinged to a second connecting rod 604. The second connecting rod 604 is hinged to the indicator block 602. The indicator block 602 is slidably connected to the detection platform 1. The detection platform 1 is provided with a display area 605 that cooperates with the indicator disk 601 and the indicator block 602.

[0026] The rotation of the detection rod 4 drives the rotation of the rotating shaft 5, which in turn drives the rear indicator disk 601 to rotate. Simultaneously, the rotation of the rotating shaft 5 also drives the rotation of the first connecting rod 603, which in turn drives the movement of the second connecting rod 604. The second connecting rod 604 then causes the indicator block 602 to slide left and right. Both the indicator block 602 and the indicator disk 601 have raised arrows that correspond to the display area 605 on the detection table 1. The display area 605 contains different marking lines. The thickness of the sheet metal is fed back through the raised arrows and their corresponding marking lines, providing more accurate thickness differences between sheet metals. To improve the feedback sensitivity of the indicator disk 601 and the indicator block 602, an acceleration gear set is installed between the indicator disk 601 and the rotating shaft 5, including a large acceleration gear 6. 07 is connected to the rotating shaft 5, the accelerating pinion 606 is connected to the indicator disk 601, and the accelerating gear 607 meshes with the accelerating pinion 606. At this time, the small-amplitude rotation of the rotating shaft 5, through the action of the accelerating gear set, causes the indicator disk 601 to rotate at a larger angle, making the feedback of the indicator disk 601 more sensitive. At the same time, in order to make the feedback of the indicator block 602 more sensitive, the length of the first connecting rod 603 is greater than the length of the detection rod 4. The longer the length of the first connecting rod 603, the greater the range of motion at the end of the first connecting rod 603. When the rotating shaft 5 rotates, the first connecting rod 603 drives the second connecting rod 604 to swing at a relatively large angle, so that the second connecting rod 604 drives the indicator block 602 to have a larger displacement distance, making the feedback display of the indicator block 602 to the detection rod 4 more intuitive and accurate.

[0027] The end of the detection rod 4 is connected to a pin, and a roller 608 is rotatably connected to the pin. The roller 608 contacts the upper surface of the material plate. The rolling connection between the roller 608 and the material plate replaces the sliding connection between the detection rod 4 and the material plate, reducing the coefficient of friction on the upper surface of the material plate and preventing scratches from appearing on the upper surface of the material plate.

[0028] The material conveying roller 3 is used for conveying the material plate. It works in conjunction with the first feeding roller 301 and the second feeding roller 302. There are three first feeding rollers 301 and two second feeding rollers 302. The three first feeding rollers 301 rotate synchronously in the same direction, while the second feeding rollers 302 rotate in the opposite direction. The connecting gear 305 on the second feeding roller 302 meshes with the drive gear 303 of the first feeding roller 301. The two second feeding rollers 302 are located and cooperate with the two first feeding rollers 301 on both sides. At the same time, in order to keep the first feeding rollers 301 rotating synchronously in the same direction, the reversing gear 304 cooperates between two adjacent drive gears 303. The drive gear 303, the reversing gear 304 and the connecting gear 305 have the same module. By working together, the first feeding rollers and the second feeding rollers 302 have the same rotation speed but opposite directions.

[0029] Furthermore, to ensure that there are no impurities on the surface of the material plate, a cleaning roller 307 is installed between the two second feeding rollers 302. The cleaning roller 307 is driven by a transmission gear 306, which meshes with a connecting gear 305, so that the cleaning roller 307 and the second conveying roller rotate in opposite directions. The cleaning roller 307 cleans the surface of the material plate to prevent debris from remaining on the material plate and affecting the detection rod 4's detection of the material plate thickness.

[0030] The two ends of the pressure roller 7 are connected to the support block 8 by pins, and the pins and the support block 8 are rotatably connected. The support block 8 supports and fixes the pressure roller 7, ensuring that the pressure roller 7 can rotate stably. The support block 8 is provided with a guide rod 9, which is fixed on the support plate 10. Under the action of the guide rod 9, the support block 8 has the freedom of vertical movement, so that the distance between the pressure roller 7 and the upper surface of the detection table 1 can be adjusted. A spring 11 is sleeved on the guide rod 9, and the spring 11 exerts a downward force on the support block 8. During the operation, the spring 11 can ensure that the pressure roller 7 presses the material plate on the detection table 1, avoiding gaps between the material plate and the detection table 1, ensuring the accuracy of thickness detection. At the same time, the pressure roller 7 can automatically adjust its horizontal height according to the thickness of the material plate, avoiding the problem of material plate deformation caused by excessive pressure from the pressure roller 7.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
