Description

Technical Field

[0001] This utility model relates to the technical field of roller compensation devices, specifically a roller compensation device for online monitoring of the thickness of rolled materials. Background Technology

[0002] Roller compensation devices are auxiliary components used in industry to correct roller misalignment. They can compensate for positional deviations caused by uneven force, temperature deformation, or uneven material loading. They typically use elastic elements such as springs or cylinders, or simple mechanical structures, to adjust the roller position in real time. This is used to prevent conveyor belt misalignment, ensure uniform thickness of rolled parts, and ultimately make equipment operation more stable and precise. They are commonly found in mining, logistics, and metallurgy industries.

[0003] In existing technologies, roller compensation devices are implemented using a manually operated mechanical adjustment system. Operators must periodically use thickness measuring tools to sample and measure the thickness of the calendered material. When the material thickness exceeds the allowable error range, the operator manually rotates the adjusting screws on both sides of the rollers, using the screw's thread transmission to change the lifting height of the upper roller, thereby adjusting the distance between the rollers. During the adjustment process, the machine must be stopped multiple times to remeasure the material thickness until the roller spacing is adjusted to meet the required material thickness, thus achieving roller spacing compensation and ensuring the thickness of the calendered material remains within a certain range.

[0004] This roller compensation method requires manual sampling and inspection, and machine stoppage adjustment. It has a significant lag in response to thickness anomalies, which easily produces a large number of defective products. Frequent machine stoppages severely reduce production efficiency, and the machine stoppage adjustment method disrupts the continuity of production. Especially in large-scale continuous production scenarios, it will cause production process interruption, affect overall capacity, and make it impossible to achieve rapid adjustment of roller gap. To address the above problems, a roller compensation device for online monitoring of calender thickness is proposed. Utility Model Content

[0017] By adopting the above technical solution, a filter screen is installed at the input end of the exhaust fan to prevent dust from entering the exhaust fan and causing damage to it.

This utility model provides an online monitoring roller compensation device for calendered material thickness. First, it uses an infrared detector to detect the material thickness in real time, which can quickly capture thickness anomalies. With the drive of a hydraulic cylinder, the frame can drive the roller assembly to quickly and accurately adjust the roller gap, thereby controlling the material thickness within a very small error range to meet the needs of high-precision production. For example, in the fields of precision metal foil and high-end papermaking, it can effectively improve product consistency. The entire adjustment process is driven by automated components such as servo motors and hydraulic cylinders, realizing the automation and real-time performance of roller gap adjustment. When the material thickness fluctuates, the system can respond immediately and complete the adjustment, avoiding material waste and production stagnation caused by the lag of manual adjustment, and significantly improving production efficiency.

[0023] 2. This utility model provides an online thickness monitoring roller compensation device for calendered materials. By utilizing gear meshing transmission, the rotation direction of the brush is opposite to that of the roller. The brush can thoroughly wipe the roller surface in reverse, effectively removing residual materials, dust, impurities, etc., ensuring the roller surface is clean and avoiding the impact of impurities on the quality of subsequent material processing, such as preventing defects such as indentations and stains on the material surface. Regular cleaning can reduce wear and corrosion on the roller surface, extend the service life of the roller, avoid equipment failure caused by long-term accumulation of impurities on the roller surface, and reduce the frequency of equipment maintenance and repair costs.

An upper roller 11 is rotatably connected through and to the bottom of the inner wall of the frame 6. A driven bevel gear 8 is fixedly connected to one end of the upper roller 11. The top and The driven bevel gear 8 at the bottom drives the upper roller 11 or the lower roller to rotate. The other end of the upper roller 11 is fixedly connected to the first gear 12.

A cleaning component is provided on the top of the inner wall of the frame 6.

[0030] Reference Figure 3The cleaning assembly includes a rotating roller 14, which is rotatably connected to the top of the inner wall of the frame 6. A second gear 15 is fixedly connected to the other end of the outer ring of the rotating roller 14.

The input end of the exhaust fan 19 is fixedly connected through the collection box 18.

[0031] Working principle: First, the servo motor 4 drives the limit rod 5 to rotate. The rotation of the limit rod 5 drives the top and bottom drive bevel gears 10 to rotate synchronously. Through the meshing between the bevel gears, the upper roller 11 and the lower roller rotate in opposite directions. When the infrared detector 23 detects an abnormality in the material thickness, the hydraulic cylinder 21 is driven to move the frame 6 up or down. During the movement, the frame 6 moves the outer shell 7, which in turn drives the rotating shaft 9 to move synchronously. This causes the rotating shaft 9 to slide up and down on the outer ring of the limit rod 5, and the rollers are always... In operation, the rollers adjust the distance between them and monitor the material thickness in real time. As the rollers rotate, the corresponding first gear 12 rotates. The rotating roller 14 rotates through the meshing of the gears, and the direction of rotation is opposite to that of the corresponding roller. This causes the brush 16 to wipe the surface of the rollers. The vacuum fan 19 draws out the negative pressure in the collection box 18, and then through the hose 20 and the bottom rotating roller 14, the dust suction port 17 draws out and rolls the dust or impurities into the collection box 18, thereby cleaning the rollers.
