Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of length measuring devices, specifically a device for measuring the length of O-state material plates. Background Technology
[0002] Currently, some high-end aluminum plate customers frequently process O-state aluminum sheets. These are products that have undergone full annealing to achieve their minimum strength, resulting in a soft texture. Currently, a measuring wheel connected to an encoder is used to measure the sheet length. The sheet is placed on the measuring wheel, and a pressure roller presses down on the surface to maintain contact. As the sheet moves, it drives the measuring wheel to rotate, allowing the encoder to determine the length. However, due to the softness of O-state aluminum, traditional metal measuring wheels easily scratch or deform the sheet. Furthermore, if the measuring wheel is covered with soft rubber, severe deformation under pressure can cause measurement errors and inaccurate results. Utility Model Content
[0003] To address the problem that excessive deformation of existing rubber-coated measuring wheels under pressure can cause measurement errors, this invention provides a device for measuring the length of O-state material sheets. This device not only prevents scratches on the sheet during measurement but also ensures measurement accuracy.
[0004] The technical solution is as follows: A device for measuring the length of O-state material sheet, comprising a measuring component, a pressing component, and a supporting component. The measuring component and the supporting component are located below the O-state material sheet, and the pressing component is located above the O-state material sheet. The pressing component includes a pressing element, and the measuring component includes a measuring wheel with an external rubber coating. The supporting component includes supporting wheels disposed on both sides of the measuring component. The pressing element is located directly above the supporting wheel and the measuring wheel, and its bottom contact surface is at the same height. The supporting wheel is connected to a deformation buffer structure. The top of the supporting wheel contacts the bottom of the O-state material sheet, and the top of the supporting wheel is higher than the top of the measuring wheel. When the pressing element applies pressure to the supporting wheel, the deformation buffer structure can undergo elastic deformation, causing the top of the supporting wheel to drop to be flush with the top of the measuring wheel.
[0005] Furthermore, the load-bearing component includes a mounting bracket, which is mounted on the load-bearing platform and located on both sides of the load-bearing wheel and connected to the load-bearing wheel via bearings.
[0006] Furthermore, the deformation buffer structure includes a mounting groove and a buffer spring. The mounting groove is provided on the top of the bearing platform. The bottom of the mounting bracket is slidably connected to the bearing platform and extends into the mounting groove. The buffer spring is provided in the mounting groove, and the bottom of the mounting bracket is in contact with the buffer spring.
[0007] Furthermore, the deformation buffer structure is a soft rubber layer covering the outer periphery of the bearing wheel.
[0008] Furthermore, the pressing assembly also includes a connecting beam, a guide frame cylinder, and a pressing platform. The guide frame cylinder is fixedly installed on the beam. The pressing platform is connected to the guide frame cylinder and is driven to move up and down by the guide frame cylinder. The pressing component is connected below the pressing platform.
[0009] Furthermore, the pressing component consists of multiple pressing rollers, with the bottom of each roller at the same height.
[0010] Furthermore, the pressing component is a horizontally arranged pressure roller.
[0011] Furthermore, the measuring wheel has an external rubber coating with a hardness of HS120A and a thickness of 2mm.
[0012] Beneficial effects: By setting a bearing wheel with its top higher than the measuring wheel, the pressing component first presses onto the bearing wheel when pressed down. Then, relying on the deformation generated by the deformation buffer structure, the O-state material sheet gradually descends until it contacts the measuring wheel. The bearing wheel and deformation buffer structure not only buffer the impact of the pressing component, preventing severe deformation of the measuring wheel's outer rubber coating due to large impacts, but also distribute the weight of the O-state material sheet. The measuring wheel only needs to bear a portion of the pressure, further reducing deformation and ensuring measurement accuracy. In addition, by making the outer rubber coating of the measuring wheel HS120A with a thickness of 2mm, not only can scratches on the O-state material sheet be avoided, but sufficient hardness can also further prevent deformation of the rubber layer.

[0014] Figure 2 This is a structural schematic diagram of Embodiment 2 of the present invention;
[0015] Figure 3 for Figure 2 Enlarged diagram of point A in the middle. Detailed Implementation
[0016] Example 1: As Figure 1The device shown is for measuring the length of O-state material sheet. It includes a measuring component, a pressing component, and a bearing component. The measuring component and the bearing component are located below the O-state material sheet, and the pressing component is located above the O-state material sheet. The pressing component includes a pressing element 1. The measuring component includes a measuring wheel 2 with external rubber coating. The bearing component includes bearing wheels 3 located on both sides of the measuring component. The pressing element 1 is located directly above the bearing wheel 3 and the measuring wheel 2, and its bottom contact surface is at the same height. The bearing wheel 3 is connected to a deformation buffer structure. The top of the bearing wheel 3 contacts the bottom of the O-state material sheet, and the top of the bearing wheel 3 is higher than the top of the measuring wheel 2. When the pressing element 1 applies pressure to the bearing wheel 3, the deformation buffer structure can undergo elastic deformation and lower the top of the bearing wheel 3 to be flush with the top of the measuring wheel 2.
[0017] Specifically, the load-bearing assembly includes a mounting bracket 4, which is mounted on the load-bearing platform 5. The mounting bracket 4 is located on both sides of the load-bearing wheel 3 and connected to the load-bearing wheel 3 via bearings. The pressing assembly also includes a connecting beam 6, a guide frame cylinder 7, and a pressing platform 8. The guide frame cylinder 7 is fixedly mounted on the beam 6. The pressing platform 8 is connected to the guide frame cylinder 7 and is driven to move up and down by the guide frame cylinder 7. The pressing component 1 is connected below the pressing platform 8.
[0018] In this embodiment, the deformation buffer structure is a soft rubber layer 300 covering the outer periphery of the bearing wheel 3. When the pressing component is pressed down, the soft rubber layer 300 can cause the top of the bearing wheel 3 to drop through its own deformation. Meanwhile, in this embodiment, the pressing component 1 consists of multiple rubber-coated pressure rollers, with the bottom of each roller at the same height.
[0019] Example 2:
[0020] The deformation buffer structure and pressure-covering component 1 differ from those in Embodiment 1, such as... Figure 2 , Figure 3 As shown, the pressing component is a horizontally arranged rubber-coated pressure roller. The deformation buffer structure includes a mounting groove 9 and a buffer spring 10. The top of the bearing platform 5 is provided with the mounting groove 9. The bottom of the mounting bracket 4 is slidably connected to the bearing platform 5 and extends into the mounting groove 9. The buffer spring 10 is provided in the mounting groove 9. The bottom of the mounting bracket 4 contacts the buffer spring 10. When the top of the bearing wheel 3 is compressed, the top of the bearing wheel 3 can be lowered by the compression of the buffer spring 10.
[0021] With the above structure, when the pressure roller or pressure wheel of the pressing component 1 descends, the top of the bearing roller 3, which is higher than the measuring roller 2, is the first to be subjected to force. This allows the impact generated by the contact to be buffered by the deformation buffer structure of the bearing roller 3. As the pressing component 1 continues to descend, the deformation buffer structure deforms, causing the bearing roller 3 to descend further until the top of the bearing roller 3 is flush with the top of the measuring roller 2. At this time, the O-state material plate can contact the measuring roller 2, causing the measuring roller 2 to rotate with the movement of the plate, thereby driving the encoder connected to the measuring roller 2 to count. During this process, since the pressure and the weight of the plate are distributed by the two bearing rollers, the deformation of the adhesive layer on the surface of the measuring roller 2 can be reduced, ensuring measurement accuracy. In addition, by placing the pressing component 1 above the measuring roller 2 and the bearing roller 3 and having the bottom contact surface at the same height, the contact surface between the pressing component 1 and the plate is always in a horizontal state, avoiding bending the plate.
[0022] In addition, as a preferred embodiment, the measuring wheel 2 spindle is made of 40Cr material, and the main body of the measuring wheel is made of aluminum alloy, which reduces the overall weight, reduces inertia, and improves measurement accuracy. The outer rubber coating is only about 2mm thick, and the hardness of the rubber is HS (Shore Hardness) 120A. This is much thinner and much harder than the existing ordinary rubber-coated measuring wheels, so that the diameter of the measuring wheel changes very little with temperature and pressure changes during use, further improving the accuracy of the measuring wheel.
[0023] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
