Description

Technical Field

[0001] This utility model relates to the field of rubber roller testing technology, specifically a device that can quickly measure the surface parameters of rubber rollers. Background Technology

[0002] Rubber rollers are used in the optical film coating process, serving as both master film rollers and gap rollers. However, due to variations in roller length, diameter, and hardness, effective surface inspection of the processed rubber rollers is impossible within the optical film factory. This lack of pre-processing inspection leads to rollers failing to meet current requirements, resulting in significant time wasted on continuous roller replacements. Using traditional dial indicators or micrometers to measure the roller surface can damage the surface, and measuring the central areas is difficult.

[0003] A search revealed a Chinese patent with publication number CN210089671U, which discloses a measuring device for rubber rollers. The device includes a frame with a clamp for fixing the rubber roller rotatably mounted on it. At least two radial measuring heads are movably mounted on the frame. Each radial measuring head includes a fixed cylinder and a movable head movably mounted within the fixed cylinder. The distance the movable head moves inward is displayed on a screen fixed to the frame. The advantages of this technical solution are: the clamp can fix the rubber roller and rotate it during testing, allowing the entire circumference of the roller to be detected; the radial measuring heads are movable, enabling testing at any position on the roller. In practical use, the testing point can be selected according to the actual situation, making the testing more flexible and the results more accurate. However, existing technologies cannot guarantee measurement accuracy while avoiding scratches or indentations on the surface of the flexible rubber roller. This results in the roller failing to meet the micron-level precision requirements for optical film production after being installed on the machine, and may even lead to the roller being scrapped. In addition, existing technologies cannot conveniently and effectively measure the middle area of ​​the rubber roller, resulting in incomplete and inaccurate detection of key parameters such as the straightness and roundness of the roller.

[0004] Therefore, based on the above-mentioned search and combined with existing technology, a device for rapidly measuring the surface parameters of rubber rollers is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0015] 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.

[0016] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "top", "bottom", "side", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] In one typical implementation of this application, please refer to Figures 1-5 As shown, a device for rapidly measuring the surface parameters of a rubber roller includes: a support frame assembly, a detection assembly, and an electrostatic elimination assembly.

[0018] The support frame assembly constitutes the basic motion and support structure of the device. This assembly includes two parallel bases 1, with a roller 2 rotatably connected between them via bearings. The roller 2 allows the entire device to roll smoothly along the surface of the rubber roller. A sleeve rod 3 is fixedly mounted above the roller 2 between the two bases 1. A detachable connecting column 4 is slidably mounted on the sleeve rod 3, and a bracket 5 is fixedly mounted on the outer surface of the connecting column 4. A handle 6 is fixedly mounted on the top surface of the bracket 5 for easy gripping and pushing of the device by the operator.

[0019] The detection component, serving as the core measuring unit, is mounted on the bracket 5. Specifically, a mounting groove 7 is formed on the top surface of the end of the bracket 5, and the dial indicator 8 is fixedly mounted in the side wall of the mounting groove 7. A mounting bracket 9 is fixedly mounted on the end of the measuring rod of the dial indicator 8, and a measuring wheel 10 is rotatably connected to the mounting bracket 9 via a rotating shaft and bearings. The measuring wheel 10 is preferably made of engineering plastic or a smooth-surfaced soft metal to ensure that it forms rolling contact with the surface of the rubber roller.

[0020] An electrostatic elimination assembly is integrated into the bracket 5 to automatically eliminate static electricity on the surface of the rubber roller before measurement. This assembly includes a connecting plate 11 fixedly mounted on the bottom surface of the bracket 5, with a fixing block 12 fixedly mounted on the bottom surface of the connecting plate 11. A sliding groove 13 is formed on the side wall of the fixing block 12. The electrostatic elimination assembly also includes: a limiting rod 14 fixedly mounted in the inner wall of the sliding groove 13; a sliding block 15 slidably fitted onto the outer surface of the limiting rod 14; and an electrostatic induction plate 16 fixedly mounted on the side wall of the sliding block 15. A spring 17, fitted onto the outer surface of the limiting rod 14, has one end connected to the side wall of the sliding groove 13 and the other end connected to the side wall of the sliding block 15, providing an elastic preload force towards the surface of the rubber roller for the sliding block 15 and the electrostatic induction plate 16. A micro switch 18 is fixedly mounted on the side wall of the sliding groove 13 facing the sliding block 15. An ion gun 19 is fixedly mounted on the top surface of the connecting plate 11 and is electrically connected to the micro switch 18.

[0021] Based on the above features, when the operator holds the handle 6 and places the device on the rubber roller, the electrostatic induction plate 16 at the front end makes slight contact with the surface of the rubber roller under the action of the spring 17. If there is significant static electricity on the surface of the rubber roller, the electrostatic attraction force will overcome the elastic force of the spring 17, attracting the electrostatic induction plate 16 and the sliding block 15 to move into the sliding groove 13, thereby triggering the micro switch 18. After the micro switch 18 is triggered, the ion gun 19 is immediately activated. The positive and negative ion streams generated by the ion gun 19 are blown onto the surface of the rubber roller, quickly neutralizing the static charge on it. After the static electricity is eliminated, the operator smoothly pushes the device, the roller 2 ensures smooth movement, and the measuring wheel 10 converts the micro-undulations (such as roundness or straightness errors) on the surface of the rubber roller into accurate readings of the dial indicator 8, thereby achieving fast and non-destructive measurement.

[0022] It is worth mentioning that the sliding fit structure between the connecting column 4 and the sleeve rod 3 allows for stepless adjustment of the position of the detection component over a wide range. This design enables the device to measure not only standard-sized rubber rollers, but also easily handle ultra-large diameter rollers or rollers requiring measurement of specific axial positions (such as the middle area of ​​the roller, which is difficult to reach using traditional methods), greatly expanding the device's applicability. By precisely moving the measuring wheel 10 to the area to be measured through the sliding connecting column 4, and adjusting and locking the angle of the bracket 5, measurement can begin, effectively solving the pain point of difficulty in measuring the middle position of the rubber roller in the prior art.

[0023] Furthermore, the electrostatic elimination component constitutes an intelligent closed-loop control system. It directly senses the presence of electrostatic force through a mechanical structure (spring 17, sliding block 15, and electrostatic induction plate 16) and converts it into a trigger signal (microswitch 18 actuates), automatically activating the ion gun 19. This combination of pure mechanical sensing and electrical actuation eliminates the need for complex electronic sensors and controllers, ensuring reliability while reducing manufacturing costs, making it highly suitable for industrial environments.

[0024] The support frame assembly is manually driven; the operator applies force via handle 6 to make roller 2 roll on the rubber roller surface. This manual drive method is simple in structure, flexible in operation, and requires no electricity, making it particularly suitable for rapid and frequent testing operations in the workshop.

[0025] The bracket 5 and the connecting column 4 can be fixed at a relative angle using locking screws (not shown in the figure), so that the measuring wheel 10 can contact the rubber roller surface with different curvatures at the optimal angle, ensuring the accuracy of the measurement data.

[0026] The material of the measuring wheel 10 is not limited to the aforementioned materials. It can also be made of materials with low friction coefficient and non-stick properties, such as polyurethane and Teflon, to further protect the surface of the rubber roller and adapt to different industrial environments.

[0027] Working principle: In use, the operator gently places the entire device onto the surface of the rubber roller to be tested using handle 6. The roller 2 at the bottom of the device contacts the surface of the rubber roller, forming a stable rolling support.

[0028] First, the static elimination component located at the front of the device begins to operate. Under the preload of spring 17, the electrostatic induction plate 16 maintains slight contact with the surface of the rubber roller. When there is a significant static charge on the surface of the rubber roller, the resulting electrostatic attraction force overcomes the elastic force of spring 17, attracting the electrostatic induction plate 16 and the connected sliding block 15 to move along the limiting rod 14 into the sliding groove 13. This movement ultimately triggers the micro switch 18 fixed in the groove. The micro switch 18 then connects the circuit, activating the ion gun 19. The ion gun 19 sprays positive and negative ion streams to neutralize the static electricity on the surface of the rubber roller, effectively eliminating the interference of static electricity on subsequent precision measurements and preventing dust adsorption.

[0029] After static electricity is eliminated, the operator smoothly pushes handle 6, causing the device to move along the axial direction of the rubber roller via roller 2 for measuring straightness or circumferentially for measuring roundness. During this process, the modified detection component performs its core measurement function: the measuring wheel 10 rolls on the surface of the rubber roller, converting the micro-undulations on the roller surface, i.e., roundness or straightness errors, into its own vertical displacement; this displacement is precisely transmitted to the detection rod of dial indicator 8, and the reading is displayed in real time on the dial or digital display screen of dial indicator 8. The operator records the changes in readings throughout the process, and can then calculate the various key form and position tolerances of the rubber roller.

[0030] It is worth mentioning that the lateral position of the entire detection assembly relative to the base 1 can be easily adjusted by sliding the connecting column 4 on the sleeve rod 3. This design allows the measuring wheel 10 to be accurately and conveniently positioned at any axial measuring point of the rubber roller, especially the middle area of ​​the rubber roller that is difficult to reach by traditional methods, thereby realizing rapid and non-destructive testing of long, large-diameter rubber rollers across the entire range.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
