Example Embodiment
[0043] Example 1
[0044] Such as figure 1 As shown, figure 2 As shown, the device for on-line automatic thickness detection of rubber-plastic coils includes a base 1, a guide roller 2, a reference roller 3, and a beam 5 provided on the base 1, and a sliding fixed plate 4 provided on the beam 5; The sliding fixing plate 4 is slidingly connected with the cross beam 5;
[0045] There is a groove on the sliding and fixing plate 4, and the reference roller 3 is arranged directly below the groove; a light source 41 is horizontally arranged on the inner side of the groove, and an image is arranged horizontally on the surface opposite to the light source 41 Sensor 42;
[0046] An eddy current sensor 43 is arranged on the groove, and the eddy current sensor 43 is located directly above the reference roller 3; the bottom surface of the probe of the eddy current sensor 43 is arranged directly opposite to the reference roller 3;
[0047] The bottom surface of the probe of the eddy current sens...
Example Embodiment
[0058] Example 2
[0059] More specifically, on the basis of Example 1, such as image 3 As shown, the method for on-line automatic thickness detection of rubber-plastic coils includes the following steps:
[0060] S1: Correct the device;
[0061] S2: The material 6 to be measured is guided by the traction guide roller 21, and the material 6 to be measured is guided away by the separation guide roller 22 after bypassing the reference roller 3;
[0062] S3: The CCD measuring instrument measures the distance between the surface of the measured material and the bottom surface of the eddy current sensor 43 to obtain a CCD measurement value of 7;
[0063] S4: The eddy current sensor 43 measures the distance between the bottom surface of the eddy current sensor 43 and the top surface of the reference roller 3 to obtain the eddy current sensor measurement value 8;
[0064] S5: Obtain the thickness of the measured material 6 according to the CCD measurement value 7 and the eddy current sensor m...

Abstract
The invention provides a device for on-line automatic thickness detection of a rubber and plastic coiled material. The device comprises a base, a guide roller, a reference roller, a cross beam and a sliding fixing plate, wherein the guide roller, the reference roller and the cross beam are arranged on the base; the sliding fixing plate is arranged on the cross beam and is connected to the cross beam in a sliding manner; a groove is arranged in the sliding fixing plate, and the reference roller is arranged right below the groove; a light source is horizontally arranged on one side of the innerside of the groove, and an image sensor is horizontally arranged on the surface opposite to the light source; an eddy current sensor is arranged in the groove, and the eddy current sensor is arrangedright above the reference roller; an eddy current sensor probe directly faces the reference roller; and the eddy current sensor probe is arranged below the horizontal light emitted by the light source. The invention further provides a method for on-line automatic thickness detection of the rubber and plastic coiled material. Through the arrangement of the reference roller and the sliding fixing plate, the thickness of the measured material is measured through the eddy current sensor and the image sensor, the real-time and nondestructive detection is realized, on the one hand, the waste of themeasured sample is avoided, and on the other hand, the measurement is comprehensive, and the precision of the data obtained through measurement is high.
Description
technical field [0001] The invention relates to the technical field of coil thickness measurement, and more specifically, relates to a device for automatically detecting the thickness of rubber and plastic coils online, and also relates to a method for automatically detecting the thickness of rubber and plastic coils online. Background technique [0002] Non-conductive rubber and plastic materials such as laminated materials, artificial leather with base cloth, coating materials, foamed materials, embossed materials, calendered sheets, rubber and plastic coils, extruded sheets, non-woven fabrics and composite materials are mainly Used in industrial production and daily life. In the production process, due to the complexity of the production process, the produced material will have uneven thickness. Because of the uneven density inside the material, it is impossible to accurately measure the thickness value using penetrating sensors such as X-rays or K85 rays. [0003] At p...
