[0034] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0036] The waste storage box 33 is used to store waste from the conveyor belt body 2 after cutting and testing;

[0037] Also includes:

[0038] A temperature-controlled unwinding mechanism, on which a conveyor belt body 2 is wound;

[0039] See also Figure 1 , Figure 2 and Figure 3 As shown, the temperature-controlled unwinding mechanism includes a winding roller 9 rotatably connected to the frame 1, a winding motor 10 is installed on the side of the frame 1, the output shaft end of the winding motor 10 is fixedly connected to the winding roller 9, and the conveyor belt body 2 is wound on the winding roller 9;

[0041] When the conveyor belt body 2 is released, the conveyor belt body 2 can be heated by the setting of the electric heating plate 11, and the conveyor belt body 2 can be cooled by the setting of the semiconductor refrigerator 13;

[0042] By setting the electric heating plate 11 and the semiconductor refrigerator 13, the surface temperature of the conveyor belt body 2 during tear detection is controlled, and the tear resistance detection operation of the conveyor belt body 2 under different temperature conditions is realized by controlling the surface temperature of the conveyor belt body 2;

[0043] Furthermore, by setting the releasable structure of the conveyor belt body 2 with the winding roller 9, repeated detection of the longitudinal tear resistance detection and the transverse tear resistance detection of the conveyor belt body 2 can be realized. By realizing the repeated detection function, the detection device can obtain multiple sets of data during detection. By obtaining multiple sets of data, the detection accuracy of the detection device and the credibility of the detection data are effectively improved.

[0044] A cleaning brush member linked to the winding roller 9 is installed on the frame 1;

[0045] See also Figure 2 and Figure 3 As shown, the brush cleaning member includes a brush cleaning roller 15 rotatably connected to the frame 1, the brush cleaning roller 15 is connected to the winding roller 9 through a belt, a dust suction chamber is provided inside the brush cleaning roller 15, a plurality of dust suction strip holes 16 distributed in a circumferential array and connected to the dust suction chamber are provided on the brush cleaning roller 15, a group of rubber bristles 17 distributed in a circumferential array are installed on the brush cleaning roller 15, the rubber bristles 17 are in contact with the conveyor belt body 2, a negative pressure vacuum cleaner 18 is installed on the frame 1, and the dust suction end of the negative pressure vacuum cleaner 18 is connected to the dust suction chamber;

[0046] When the conveyor belt body 2 is released from the winding roller 9, the winding roller 9 rotates, and after the winding roller 9 rotates, it drives the cleaning brush roller 15 to rotate. After the cleaning brush roller 15 rotates, the surface of the conveyor belt body 2 is cleaned by the rubber brush 17.

The surface of the conveyor belt body 2 is physically and synchronously cleaned by negative pressure, thereby improving the cleanliness of the surface of the conveyor belt body 2 and reducing the dirt content on the surface of the conveyor belt body 2.

[0047] By improving the surface cleanliness of the conveyor belt body 2 and reducing the contamination rate of the conveyor belt body 2, the first optical camera 4 and the second optical camera 8 can effectively reduce the optical imaging detection error caused by debris and impurities on the surface of the conveyor belt body 2 when performing optical imaging detection intensity on the conveyor belt body 2, thereby effectively improving the optical detection accuracy of the device;

[0048] See also Figure 1 , Figure 4 As shown, two detection drive mechanisms are connected to two symmetrically arranged detection arms 3 with adjustable spacing, and the two-axis position and angle of the two detection arms 3 are adjustable;

[0050] The detection drive mechanism includes a rotating frame 21 and an axial linear transmission module 19 installed on the frame 1, and the axial linear transmission module 19 is transmission-connected with a moving seat 20, and the moving seat 20 is slidably connected to the frame 1;

[0051] An electric rotator 22 is installed on the top surface of the moving seat 20, and the rotating surface of the electric rotator 22 is fixedly connected to the rotating frame 21. A pitch-adjusting screw 23 driven by a motor is rotatably installed between the inner surfaces of the rotating frame 21.

The positive thread segment and the negative thread segment are respectively connected to the two detection arms 3 in a transmission manner. Both the two detection arms 3 are slidably connected to the rotating frame 21.

[0052] By setting the positive thread segment and the negative thread segment, the two detection arms 3 can be synchronously approached or synchronously moved away from each other. By the synchronous approaching or synchronously moving away from each other of the two detection arms 3, the distance between the two detection arms 3 is quickly changed. By changing the distance between the two detection arms 3, the clamping state of the detection arms 3 on the conveyor belt body 2 is controlled.

[0053] By means of the rotatable structure of the electric rotator 22 and the rotating frame 21, the detection device can be switched between the longitudinal tear resistance detection mode and the transverse tear resistance detection mode;

[0054] When the device performs the longitudinal tear resistance detection mode of the conveyor belt body 2, the first detection components on the two detection drive mechanisms are arranged opposite to each other.

[0058] The single chip computer 14 has an image detection and analysis module that cooperates with the first optical camera 4 and the second optical camera 8 built in. The image detection and analysis module is an image detection and analysis algorithm. The image detection and analysis module performs real-time imaging analysis on the image data collected by the first optical camera 4 and the second optical camera 8;

[0059] The first optical camera 4 and the second optical camera 8 can be customized or selected according to actual needs;

[0060] A double-axis driving platform 5, on which a pick-up platform 6 capable of double-axis movement is mounted;

[0061] The dual-axis driving platform 5 is a common component in the prior art and will not be described in detail here. The dual-axis driving platform 5 is used to drive the picking platform 6 to perform dual-axis movement;

[0062] See also Figure 4 and Figure 5As shown, the picking platform 6 is connected to two picking clamps 7 with adjustable spacing for picking up the conveyor belt body 2, and the inner wall of the picking platform 6 is installed with a group of double-headed push rods 32, and the two movable ends of the double-headed push rods 32 are respectively fixedly connected to the two picking clamps 7, and a second optical camera 8 is installed on the picking platform 6.

[0063] A single chip microcomputer 14 is installed on the frame 1 , and the data terminals of the temperature probe 12 , the first optical camera 4 and the second optical camera 8 are all data-connected to the single chip microcomputer 14 .

[0064] The first optical camera 4 and the second optical camera 8 are both arranged above the conveyor belt body 2, and the collection ends of the first optical camera 4 and the second optical camera 8 are both facing the conveyor belt body 2;

[0065] The first detection component includes a longitudinal clamp 24, which is slidably connected to the detection arm 3. A longitudinal pressure sensor 25 is installed on the detection arm 3 and corresponds to the positions on both sides of the longitudinal clamp 24. The data end of the longitudinal pressure sensor 25 is connected to the single-chip microcomputer 14.

[0066] The second detection component includes a transverse pulling clamp 26, and a group of T-shaped guide rods 27 are installed on the surface of the detection arm 3. Each T-shaped guide rod 27 is slidably connected to the transverse pulling clamp 26. An electric pull rod 28 is installed between the detection arm 3 and the transverse pulling clamp 26. A transmission ring 29 is installed on the electric pull rod 28 and at the position corresponding to the two sides of the transverse pulling clamp 26. A transverse pressure sensor 30 is installed on the surface of the transverse pulling clamp 26. The data end of the transverse pressure sensor 30 is connected to the data of the single-chip computer 14. A cutting knife 31 is installed on the surface of the transverse pulling clamp 26.

[0067] The cross section of the cutting knife 31 is a right triangle, and the length of the cutting edge of the cutting knife 31 is 1.2 times the width of the conveyor belt body 2 .

[0068] The working principle of the present invention is: by setting the electric heating plate 11 and the semiconductor refrigerator 13, the surface temperature of the conveyor belt body 2 during tear detection is controlled, and the surface temperature of the conveyor belt body 2 is controlled to realize the tear resistance detection operation of the conveyor belt body 2 under different temperature conditions, and the releasable structure setting of the conveyor belt body 2 by the roller 9 can realize repeated detection of the longitudinal tear resistance detection and the transverse tear resistance detection of the conveyor belt body 2. By realizing the repeated detection function, the detection device can obtain multiple sets of data during detection. By obtaining multiple sets of data, the detection accuracy of the detection device and the credibility of the detection data are effectively improved. When the device performs the longitudinal tear resistance detection mode, the first optical camera 4 performs real-time imaging detection on the conveyor belt body 2, and detects the surface imaging changes of the conveyor belt body 2 when the conveyor belt body 2 performs the longitudinal tear resistance detection mode and the actual machine and surface cracks of the conveyor belt body 2 when the conveyor belt body 2 is torn. The generation position and distribution law of the device, at the same time, when the device performs the longitudinal tear resistance detection mode, the two first detection components are arranged relative to each other. After the two first detection components are arranged relative to each other, the two longitudinal clamps 24 on each detection drive mechanism clamp the conveyor belt body 2. When the longitudinal clamps 24 on the two detection drive mechanisms clamp the conveyor belt body 2, the detection length of the conveyor belt body 2 when the conveyor belt body 2 performs the longitudinal tear resistance detection mode can be controlled by setting the two axial linear transmission modules 19. After the above-mentioned adjustment and setting are completed, the conveyor belt body 2 is kept in a fully relaxed state through the setting of the roller 9, and the two picking clamps 7 softly clamp the relaxed conveyor belt body 2. Subsequently, the two rotating frames 21 are sufficiently separated by the setting of the two axial linear transmission modules 19. After the two rotating frames 21 are sufficiently separated, the longitudinal pressure sensor 25 generates data feedback, and finally the tear resistance of the conveyor belt body 2 in the longitudinal direction is measured;

[0069] When it is necessary to repeat the longitudinal tear resistance detection mode of the conveyor belt body 2, the material picking clamp 7 cooperates with the winding roller 9, so that the conveyor belt body 2 to be detected re-enters the clamping area of ​​the longitudinal clamps 24 on the two detection drive mechanisms, and then the conveyor belt body 2 is repeatedly tested in the longitudinal tear resistance mode;

[0070] When the transverse tear resistance detection mode of the conveyor belt body 2 is performed, the second detection components on the two detection drive mechanisms are arranged relative to each other. After the two second detection components are arranged relative to each other, the second detection components clamp the conveyor belt body 2, and the conveyor belt body 2 is kept in a fully relaxed state through the setting of the roller 9. The two picking clamps 7 softly clamp the conveyor belt body 2 in the relaxed state. After the two picking clamps 7 softly clamp the conveyor belt body 2 in the relaxed state, the cutting knife 31 applies sufficient force to the conveyor belt body 2, and completes the cutting and segmenting of the conveyor belt body 2 to be detected from the entire conveyor belt body 2. The cut and segmented conveyor belt body 2 is clamped by the transverse pulling clamp 26. After clamping, the transverse tear resistance detection of the conveyor belt body 2 can be realized through the setting of the electric pull rod 28.

[0071] When it is necessary to repeat the transverse tear resistance test of the conveyor belt body 2, the picking clamp 7 cooperates with the winding roller 9 so that the conveyor belt body 2 to be tested re-enters the clamping area of ​​the transverse pulling clamp 26 on the two detection drive mechanisms, thereby realizing repeated transverse tear resistance test of the conveyor belt body 2.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
