[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] The purpose of this invention is to provide a marking device for the top of a large-diameter roller to solve the problems existing in the prior art. It has a simple structure, is practical and convenient, effectively improves the accuracy of marking the top surface of a large-diameter roller, and effectively improves the efficiency of maintenance work.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model provides a large-diameter roller top marking device, such as Figures 1-3 As shown, the device includes a frame 1, a level 2, and a marking medium 3. The frame 1 has a first reference plane 11 and a second reference plane 12 arranged in parallel. The second reference plane 12 is used to contact the surface of the large-diameter roller that needs to be marked. The level 2 is fixedly connected to the first reference plane 11 to indicate the relative relationship between the first reference plane 11 and the horizontal plane. The marking medium 3 is detachably fixedly connected to the frame 1 and can mark the surface of the large-diameter roller measured by the first reference plane 11 when the level 2 shows that the first reference plane 11 is parallel to the horizontal plane. Setting the first reference plane 11 and the second reference plane 12 in parallel provides a stable and clear reference for the use of the device. The contact between the second reference plane 12 and the surface of the large-diameter roller makes the device stable. The level 2 is fixed to the first reference plane 11 and can accurately indicate the relationship between the plane and the horizontal plane. Only when the first reference plane 11 is parallel to the horizontal plane can the highest point of the large-diameter roller be accurately determined. The detachably connected marking medium 3 is easy to replace, ensuring that the marking medium 3 can be adjusted in time under different working scenarios to achieve accurate marking of the surface of the large-diameter roller, improving the versatility and accuracy of the device.

[0025] In a preferred embodiment, the frame 1 is provided with a leveling cavity 13 for mounting the level 2. The bottom surface of the leveling cavity 13 forms a first reference plane 11. The leveling cavity 13 provides a dedicated mounting position for the level 2, making the level 2 more securely mounted. Using the bottom surface of the leveling cavity 13 as the first reference plane 11 ensures the flatness and stability of the first reference plane 11, thereby improving the accuracy of the level measurement and enabling more precise indication of whether the device is level.

[0026] In a preferred embodiment, the bottom surface of the frame 1 is a second reference plane 12, and a marking medium receiving cavity 14 is provided in the middle of the second reference plane 12. The marking medium 3 is used to be housed in the marking medium receiving cavity 14, and the marking end of the marking medium 3 is close to the second reference plane 12. The bottom surface of the frame 1 serving as the second reference plane 12 ensures the stability of the contact between the device and the surface of the large-diameter roller. The marking medium receiving cavity 14 is located in the middle of the second reference plane 12, so that the marking medium 3 can mark the surface of the large-diameter roller at the center position after installation, improving the accuracy and consistency of marking. The marking end of the marking medium 3 is close to the second reference plane 12, which enables timely and accurate marking of the surface of the large-diameter roller when the device is in a horizontal state, avoiding marking deviation.

[0027] In a preferred embodiment, the bottom surface of the marking medium receiving cavity 14 is higher than the second reference plane 12, so that the marking medium 3 can protrude from the marking medium receiving cavity 14. This allows for better contact with the surface of the large-diameter roller during marking, ensuring clear and accurate marking results and effectively avoiding problems such as unclear or unmarkable markings due to the concavity of the marking medium 3.

[0028] In a preferred embodiment, an elastic element 4 is also included. One end of the elastic element 4 is fixedly connected to the inner wall of the marking medium receiving cavity 14, and the other end is used to press the marking medium 3 tightly. The elastic element 4 can generate a continuous pressing force on the marking medium 3, ensuring that the marking medium 3 always maintains good contact with the surface of the large-diameter roller during the use of the device, avoiding the marking medium 3 from loosening or shifting due to vibration or other factors, thereby ensuring the continuity and stability of the marking work and reliably guaranteeing the marking quality.

[0029] In a preferred embodiment, the elastic element 4 is a spring. As an elastic element 4, the spring has good elasticity and restoring performance, which can stably maintain the pressing force on the marking medium 3. At the same time, when the marking medium 3 is consumed or replaced, it can rely on its own elasticity to restore its original state, which facilitates the maintenance and adjustment of the device.

[0030] In a preferred embodiment, the marking medium 3 is a solid pigment block, and the bottom surface of the solid pigment block is flush with the second reference plane 12. Using a solid pigment block as the marking medium 3 is convenient for storage and use, less prone to leakage, and durable. The fact that the bottom surface of the solid pigment block is flush with the second reference plane 12 ensures that the pigment block can stably contact the roller surface when the device is placed horizontally on the surface of a large-diameter roller, thereby improving the marking effect.

[0031] In a preferred embodiment, the level 2 is fixed to the frame 1 by adhesive bonding. The adhesive bonding method forms a stable connection between the level 2 and the frame 1, reducing the measurement error caused by the shaking or displacement of the level 2, and reliably maintaining the position of the level 2 on the frame 1, thereby continuously and accurately indicating the relationship between the first reference plane 11 and the horizontal plane.

[0032] The following is the usage method of the aforementioned patented large-diameter roller top marking device:

[0033] 1. Preparation

[0034] Check the integrity of the device: Carefully inspect all components, including frame 1, level 2, marking medium 3, and elastic element 4, to ensure they are complete and undamaged. Pay particular attention to whether level 2 is indicating correctly and whether marking medium 3 is intact, free from moisture or damage.

[0035] Install level 2: Since level 2 is fixed to frame 1 by adhesive bonding, this step has been completed when the device leaves the factory. Therefore, it is only necessary to confirm that level 2 is firmly connected to frame 1 and that there are no signs of loosening at the adhesive joint.

[0036] Installing Marking Medium 3: Place the solid pigment block into the marking medium receiving cavity 14, making the bottom surface of the solid pigment block flush with the second reference plane 12. During placement, ensure that one end of the pigment block is in contact with the elastic element 4 (spring). The spring will automatically apply a tightening force to ensure that the pigment block is securely located in the receiving cavity and that the marking end is close to the second reference plane 12.

[0037] 2. Placement and leveling of the device

[0038] Placement device: Place the second reference plane 12 (bottom surface of frame 1) of the device on the surface of the large-diameter roller that needs to be marked, ensuring smooth contact.

[0039] Leveling operation: Observe the level 2 fixed on the first reference plane 11 (bottom surface of the leveling cavity 13). Slowly adjust the position of the device on the surface of the large-diameter roller so that the level 2 indicates that the first reference plane 11 is parallel to the horizontal plane. At this time, the device is in the correct marked position, which can ensure the accuracy of the measurement results and determine the position of the highest point of the large-diameter roller.

[0040] 3. Marking operation

[0041] Once the level 2 indicates that the first reference plane 11 is parallel to the horizontal plane, the marking operation can begin. The device is moved slowly. Because the bottom surface of the marking medium receiving cavity 14 is higher than the second reference plane 12 and the solid pigment block protrudes from the marking medium receiving cavity 14, the protruding solid pigment block contacts and rubs against the surface of the large-diameter roller, thus leaving clear and accurate marking marks on the roller surface, achieving the marking work on the top surface of the large-diameter roller.

[0042] 4. Termination and Maintenance

[0043] End of marking work: After marking is completed, remove the device from the surface of the large-diameter roller to end the operation.

[0044] Maintenance procedures: Check the consumption of marking medium 3. If the amount of solid pigment block remaining is insufficient, remove and replace it with a new solid pigment block. Check all parts of the device for wear or damage. If necessary, repair or replace them in time. Clean the device regularly, especially the marking medium receiving cavity 14 and the parts of the device that come into contact with the surface of the large-diameter roller, to keep the device clean and tidy for the next use.
