Technical Field
[0001] The utility model belongs to the technical field of static balance correction, in particular to a roller static balance correction device. Background Art
[0002] Roller balancing and correction is an indispensable step in the roller manufacturing process. The main purpose of roller balancing and correction is to improve the balance of the roller. The balance of the roller is directly related to the equipment operation efficiency, operation energy consumption, equipment life and product quality. In many industrial fields, especially in papermaking, printing, plastics and other processing industries, rollers are key transmission and processing components. The balance state of the rollers during rotation directly affects the stability of the production line and the quality of the products.
[0003] The existing static balancing multi-purpose guide rail static balancing frame has a relatively simple structure. Its main part is two parallel knife-edge guide rails installed on the same horizontal plane. This static balancing operation is complicated, and after pushing, it cannot ensure that the two ends of the roller remain consistent, thus affecting the accuracy of correction. Utility Model Content
[0004] The utility model aims to provide a roller static balance correction device to solve the existing problems.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model is a roller static balance correction device, including a base, characterized in that: the upper surface of the base is provided with a distance adjustment movable groove, the inner wall of the distance adjustment movable groove is rotatably connected to two distance adjustment screws, one end of the two distance adjustment screws is fixedly connected to a servo motor, one side of the servo motor is fixedly connected to the base, one side of the servo motor is fixedly connected to a positioning static balance frame, the upper end of the positioning static balance frame is fixedly connected to an electromagnetic sensor, one side of the positioning static balance frame is bolted to the base, and one side of the positioning static balance frame is bolted to an electronic digital According to the analysis board, a positioning bearing groove is provided at the upper end of the positioning static balancing frame, and two positioning support shafts are rotatably connected to the positioning bearing groove relative to the two inner walls, and the two positioning support shafts are rotatably connected to the peripheral sides with positioning rolling bearings, and the peripheral sides of the adjusting screw are threadedly connected to the limited position static balancing frame, and the upper end of the limited static balancing frame is fixedly connected with the right electromagnetic sensor, and a limiting bearing groove is provided at the upper end of the limiting static balancing frame, and two limiting support shafts are rotatably connected to the limiting bearing groove relative to the two inner walls, and the two limiting support shafts are rotatably connected to the peripheral sides with limiting rolling bearings.
[0007] Furthermore, the adjustable distance moving groove is a T-shaped structure, and the two adjustable distance screws are respectively located at opposite ends of the adjustable distance moving groove, and the two adjustable distance screws both penetrate the adjustable distance moving groove and extend to the outside of the base. The correction device is adjusted according to rollers of different lengths to ensure the correct positioning and weight distribution of the balancing block, which can more accurately compensate for the unbalanced mass and thereby improve the accuracy of the balancing correction.
[0008] Furthermore, the positioning bearing grooves extend to the outside through the positioning static balance frame on opposite sides, and rollers are arranged above the positioning rolling bearing and the limiting rolling bearing, and the positioning rolling bearing and the limiting rolling bearing are both rotatably connected to the rollers.
[0009] Furthermore, small steel balls are arranged inside the positioning rolling bearing and the limiting rolling bearing to roll between the inner and outer ring tracks, thereby ensuring the accuracy and stability of the correction device during operation, which is critical for accurately measuring and adjusting imbalance; since the structure of the positioning rolling bearing and the limiting rolling bearing is relatively simple, it is easy to inspect and maintain, and it is also relatively convenient to replace the bearings when necessary, which is conducive to maintaining the equipment in the best working condition.
[0010] Furthermore, the electromagnetic sensor on the left and the electromagnetic sensor on the right are both connected to the electronic data analysis board by signals, and the servo motor is connected to the electronic data analysis board by signals, wherein the electromagnetic sensor captures the vibration signal caused by the imbalance during rotation, because these sensors can sense extremely small magnetic field changes, and then convert them into electrical signals, accurately measuring the frequency and amplitude of the vibration, and then the data collected by the electromagnetic sensor is transmitted to the electronic data analysis board through signals, and the electronic data analysis adopts the Compact PCL model digital transmission circuit board. The electronic data analysis board separates the specific frequency vibration caused by the imbalance through special software analysis, and uses the spectrum analysis technology to accurately identify the place where the unbalanced mass is generated, and calculates the position and size of the unbalanced mass according to the analysis results. Further, the electronic data analysis board will guide the operator to add or adjust the balance block at the corresponding position until the ideal static balance state is achieved, thereby reducing manual intervention and greatly improving the detection accuracy and efficiency.
[0011] The utility model has the following beneficial effects:
[0012] The utility model installs a positioning rolling bearing and a limiting rolling bearing between the rotating part of the roller and the positioning support shaft and the limiting support shaft, and utilizes a spherical small steel ball to slide between the inner and outer ring tracks to replace the sliding friction of direct contact, thereby greatly reducing the friction force and making the correction process smoother. At the same time, the rolling bearing can provide stable radial and axial support, thereby ensuring the accuracy and stability of static balance correction.
[0013] The utility model collects data through electromagnetic sensors, and the electromagnetic sensors transmit the data to an electronic data analysis board through signals. After the electronic data analysis board analyzes the results according to the data, it will guide the operator to add or adjust the balancing block at the corresponding position until the ideal static balance state is achieved, thereby reducing manual intervention and greatly improving detection accuracy and efficiency.
[0014] The utility model drives the adjusting screw through the output end of the servo motor, and the rotation of the adjusting screw drives the limited static balancing frame to adjust the distance in the distance adjustment moving groove, so that the utility model can adapt to rollers of different lengths, increasing the versatility and flexibility of the utility model. At the same time, the device can be adjusted on-site to the most suitable current roller size, which can minimize the balancing error that may be introduced due to the mismatch between the device and the roller size, ensuring that the corrected roller can reach the best operating state.

[0026] Among them, the adjustable distance movable groove 2 is a T-shaped structure, and the two adjustable distance screws 3 are respectively located at the opposite ends of the adjustable distance movable groove 2. The two adjustable distance screws 3 both penetrate the adjustable distance movable groove 2 and extend to the outside of the base 1, so that the length of the device can be adjusted to adapt to rollers 16 of different lengths, which effectively improves the versatility and flexibility of the utility model and reduces the cost of enterprises to purchase a variety of special equipment. At the same time, adjusting the correction device according to the different lengths of rollers 16 can ensure the correct positioning and weight distribution of the balancing block, so that the unbalanced mass can be compensated more accurately, thereby improving the accuracy of the balance correction.
