[0027] Reference Figure 1 and Figure 2 A rubber 30 thickness measuring device 10 is provided. The device 10 includes a thickness measuring mechanism 20, which is mounted on a frame 13 of the device 10. The thickness measuring mechanism 20 includes a movable frame 21, a detector 22, and an electric slide 23. The movable frame 21 is movably mounted on the frame 13 of the device 10. The movable frame 21 includes an upper bracket and a lower bracket. The rubber 30 is located in a gap between the upper bracket and the lower bracket. Figure 3 As shown; the detectors 22 are respectively mounted at the ends of the upper bracket and the lower bracket, and the detection directions of the two detectors are opposite to each other. The two detectors 22 are respectively located below and above the rubber 30 to detect the thickness of the lower and upper parts of the rubber 30, specifically the distance from the computing device 10 to the upper and lower surfaces of the rubber 30. The electric slide 23 is mounted on the frame 13, and the movable frame 21 is movably mounted on the electric slide 23. The electric slide 23 enables the movable frame 21 to move along the width direction of the rubber 30 so that the detection range can cover the rubber 30 as much as possible.

[0028] The present application has three embodiments for the arrangement of the detector 22 and the thickness measuring mechanism 20:

[0029] In the first embodiment, only one thickness measuring mechanism 20 is installed, and only two sensors are installed on the detector 22, specifically one sensor on the upper bracket and one sensor on the lower bracket, such as Figure 1 As shown, when the rubber 30 moves, the electric slide 23 drives the moving frame 21 to move back and forth along the width direction of the rubber 30, so as to detect the average thickness of the rubber 30. The detection path in this embodiment is as follows: Figure 6 As shown, the blue dotted line is the detection path. The detection path in the first embodiment is single, which can be applied to the situation where the uniformity of the thickness of the rubber 30 is not required to be high, which is conducive to improving production efficiency.

[0030] In the second embodiment, the thickness measuring mechanism 20 has two groups. The two groups of thickness measuring mechanisms 20 are installed on both sides of the rubber 30 along the central axis of the rubber 30. The two groups of thickness measuring mechanisms 20 are staggered. There are only two sensors installed on the detector 22, specifically one sensor on the upper bracket and one sensor on the lower bracket. The electric slide 23 drives the moving frame 21 to move back and forth along the width direction of the rubber 30 to detect the average thickness of the rubber 30. The detection path in this embodiment is as follows: Figure 7 As shown, the blue dotted line and the red dotted line are the detection paths of the two thickness measuring mechanisms 20 respectively, and the black dot is the intersection point of the detection paths of the two thickness measuring mechanisms 20. The portion of the rubber 30 at the intersection point will be detected twice, thereby improving the detection accuracy. At the same time, the two-way detection can obtain the thickness distribution of the rubber 30 through difference comparison, and can detect the thickness more accurately. It is suitable for situations where the uniformity of the thickness of the rubber 30 is required to be high. The production efficiency will be lower than that of the embodiment 1, but the accuracy will be higher than that of the embodiment 1.

[0031] In the third embodiment, the thickness measuring mechanism 20 has two groups, and the two groups of thickness measuring mechanisms 20 are installed on both sides of the rubber 30 along the central axis of the rubber 30. The two groups of thickness measuring mechanisms 20 are staggered and installed. The detector 22 includes a first sensor 221 and a second sensor 222. The first sensor 221 and the second sensor 222 are arranged side by side along the travel direction of the rubber 30. Specifically, there are two sensors on the upper bracket and two sensors on the upper bracket. The detection path in this embodiment is as follows: Figure 8 As shown, the blue dotted line and the red dotted line are the detection paths of the two thickness measuring mechanisms 20, respectively. There are two red dotted lines and two blue dotted lines, representing the detection paths of the first sensor 221 and the second sensor 222 on the same thickness measuring mechanism 20. The black dot is the intersection point of the detection paths of the two thickness measuring mechanisms 20. The portion of the rubber 30 at the intersection point will be detected twice, thereby improving the detection accuracy. Compared with the second embodiment, the black dots in the third embodiment are mostly distributed on both sides of the rubber 30, and the distribution is more even, resulting in higher detection accuracy.

[0032] It should be noted that the detection paths of the above three embodiments are all "Z"-shaped paths. In the actual production process, the moving speed of the movable frame 21 driven by the electric slide 23 can be increased so that the detection paths at the upper and lower ends of the "Z"-shaped path can be closer to improve the detection accuracy, and the above-mentioned sensors include infrared distance sensors.

[0033] As a further improvement of the above structure, the thickness measuring mechanism 20 further includes: a smoothing table 24, which is mounted on the frame 13, and the inspected part of the rubber 30 is located on the smoothing table 24; the edges of the smoothing table 24 close to and away from the traveling direction of the rubber 30 are provided with chamfered edges 241, and the part of the smoothing table 24 between the chamfered edges 241 is a smooth top surface 242. When the rubber 30 passes through the smoothing table 24, the chamfered edges 241 can enable the rubber 30 to pass smoothly through the edge of the smoothing table 24 and reach the top of the smoothing table 24, and the middle part of the smoothing table 24 has an extension channel 243, and the movable frame 21 can be embedded in the extension channel 243. The extension channel 243 is located below the inspected part to prevent the smoothing table 24 from affecting the movement of the movable frame 21. Figure 2 shown.

[0034] As a further improvement of the above structure, the device 10 further includes: a first guide roller group 11, mounted on the frame 13 and symmetrically mounted on both sides of the smoothing table 24; a second guide roller group 12, including a roller bracket 121 and a round rod 122 rotatably mounted on the roller bracket 121, and the support rod of the roller bracket 121 is rotatably connected to the frame 13; Figure 5 As shown, the rubber 30 passes from the top of the second guide roller group 12 through the bottom of the first guide roller group 11 and then enters the smoothing table 24. It should be noted that the height of the lower end of the first guide roller group 11 is lower than the height of the upper end of the smoothing table 24, so that when the rubber 30 passes through the equipment 10, the parts on both sides of the smoothing table 24 can be pushed downward by the first guide roller group 11, so that the part of the rubber 30 located on the smooth top surface 242 can be close to the smoothing table 24, avoiding fluctuations and improving the detection accuracy.

[0035] Further, such as Figure 4 As shown, the device 10 also includes: a support base 131, which is fixedly mounted on the part of the frame 13 below the support rod; a spring sheet 132, one end of which is fixedly mounted on the support base 131, and the middle part of the spring sheet 132 is against the bottom of the support rod. When other parts of the rubber 30 vibrate, the vibration of the rubber 30 will be transmitted to the round rod 122 of the second guide roller group 12, and the round rod 122 will transmit the vibration to the support rod. The spring sheet 132 can absorb the vibration of the support rod to prevent the vibration from being transmitted to the rubber 30 located on the smoothing table 24, resulting in errors in thickness detection.

[0037] Those skilled in the art will appreciate that the above embodiments are merely for the purpose of illustrating the present invention and are not intended to limit the scope of the present invention. Other variations or modifications may be made based on the above disclosure, and such variations or modifications are still within the scope of the present invention.
