Each inspection usually takes more than 1 hour to stop, which seriously affects production efficiency.

[0027] The controller body 30 is provided with a control center 40, and the control center 40 includes a reading module 41, a conversion module 42, a correction module 43 and a display module 44; the film probe 10 is provided with a piezoresistive sensor 11; the film connecting rod 20 is connected between the controller body 30 and the film probe 10, and is provided with a connection line for electrically connecting the piezoresistive sensor 11 and the control center 40;

[0028] The film probe 10 can be extended to and rolled between the two rollers, and the piezoresistive sensor 11 can generate resistance changes according to the pressure between the two rollers and output a voltage change signal to the reading module 41; the conversion module 42 can convert the voltage change signal into a pressure signal, and correct it through the correction module 43, and then display the pressure value through the display module 44.

[0029] In the utility model, the film probe 10 can be extended to and rolled between the two rollers, and rotated forward along the circumferential direction with the rotation of the rollers. In the process of rotating between the two rollers, the piezoresistor sensor 11 produces a resistance change according to the pressure between the two rollers, and outputs a voltage change signal to the reading module 41. The conversion module 42 can convert the voltage signal into a pressure signal, and then display the pressure value through the display module 44 after correction and adjustment by the correction module 43. During actual maintenance, the user can directly read the pressure value between each point of the two rollers in an intuitive and real-time manner. What you see is what you get. By comparing the test data of multiple points, the detection conclusion can be drawn, so as to calibrate and adjust the position of the rubber roller.

[0030] In this embodiment, in order to facilitate the film probe 10 and the film connecting rod 20 to extend and rotate with the rubber roller, the film connecting rod 20 and the film probe 10 are flat flexible film structures, and the connecting line is arranged inside the flexible film.

[0031] Specifically, the flexible film structure is formed by stacking two layers of flexible films, pressing and hot-melting the edges. The flexible film structure is formed by stacking two layers of flexible films, and the piezoresistive resistor sensor 11 and the connecting circuit are arranged between the two layers of flexible films and sealed by hot-melting the edges.

[0032] In this embodiment, the film connecting rod 20 is provided with a positive terminal and a negative terminal; the controller body 30 is provided with a positive connecting portion and a negative connecting portion; the positive terminal is detachably connected to the positive connecting portion; and the negative terminal is detachably connected to the negative connecting portion. This facilitates the separation and assembly of the film connecting rod 20 and the controller body 30, and facilitates placement and storage.

[0033] For example, in some embodiments, the positive terminal, the negative terminal, the positive connection portion, and the negative connection portion may be plug-in terminal structures.

[0034] For example, in some other embodiments, the positive terminal and the negative terminal are exposed connecting electrode sheets; the positive connecting portion and the negative connecting portion are compressible conductive locking blocks or pressure wheel structures, and the connecting electrode sheets extend into the conductive locking blocks or pressure wheel structures, and are pressed and locked to achieve electrical connection.

[0035] In this embodiment, in order to intuitively display the detected pressure value, the controller body 30 is provided with a display panel 31 .

[0036] In this embodiment, in order to facilitate the handheld carrying and use of the detection and calibration device, the controller body 30 is provided with a battery assembly 32 .

[0037] The two rollers are usually divided into active rollers and passive rollers in actual operation, wherein the active rollers are mostly metal rollers and the passive rollers are mostly rubber rollers. The detection method using the rubber roller pressure detection and verification device is as follows:

[0038] S1, measuring multiple pressure values ​​at the front end area, the middle area and the rear end area of ​​the gap between the two rollers by using a thin film probe 10;

[0039] S2, taking an average of multiple pressure values ​​in the front region, the middle region and the rear region, which correspond to the rubber roller pressures in the front region, the middle region and the rear region of the active roller respectively;

[0040] S3. By comparing the changes in the pressure values ​​of the rubber roller in the front area, the middle area and the rear area, it is determined whether the central axis of the rubber roller has an inclination or a swing, and the position of the active roller is corrected and checked.

[0041] S4, after calibration and verification, repeat steps S1 and S2 again to determine whether the rubber roller pressure in the front area, middle area and rear area of ​​the active roller after calibration is balanced;

[0042] If it is unbalanced, check the position of the active roller again; if it is balanced, complete the inspection and calibration of the rubber roller pressure.

[0043] Specifically, in order to improve the detection efficiency, in step S2, the pressure values ​​of three points are measured in the front area, the middle area and the rear end area respectively.

[0044] Among them, see Figure 2 In step S2, the pressure values ​​of the three points measured in the front area, the middle area and the rear area respectively can be used to draw a front equivalent circle (circle A), a middle equivalent circle (circle B) and a rear equivalent circle (circle C) along the axis of the active roller; the relative positions of the centers of the three equivalent circles and the axis of the active roller are the offset misalignment of the active roller in the front area, the middle area and the rear area.

[0045] For example, in Figure 2 In the method of determining a circle by three points, the front equivalent circle (circle A) is formed by measuring points A1, A2 and A3; the middle equivalent circle (circle B) is formed by measuring points B1, B2 and B3; the rear equivalent circle (circle C) is formed by measuring points C1, C2 and C3.

[0046] Specifically, in step S2, in order to improve the accuracy of measurement, the three points measured in the front area, the middle area and the rear end area are evenly distributed at an angle of 120 degrees on the periphery of the active roller.

These equivalent modifications and substitutions are all included in the scope defined by the claims of this application.
