Description

Technical Field

[0001] This utility model relates to the field of belt detection technology, and more specifically, to a belt tear detection device. Background Technology

[0002] The main purpose of belt tear detection is to detect and address belt tears in a timely manner to prevent safety accidents and reduce production losses. Belt tear detection includes real-time monitoring of the belt's operating status and periodic monitoring of the belt's condition. Once a belt tear is detected, it ensures that relevant personnel can handle the situation promptly, thereby preventing the accident from escalating further.

[0003] Existing belt tear detection devices need to be installed on belt conveyor equipment, which is quite cumbersome. When testing different belt conveyor equipment, the device needs to be constantly disassembled and moved. In actual use, the detection efficiency is low, which is not as efficient as removing the belt and placing it on the device for testing.

[0004] Therefore, a belt tear detection device is proposed to address the above problems. Utility Model Content

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] This solution achieves rapid fixing of belts of different widths and lengths through the cooperation of the adjustment mechanism and adjustment components. Utilizing a two-way motor to drive the rotation of a bidirectional lead screw, it synchronously moves the positioning rollers on both sides, adapting to belts of various sizes and significantly improving inspection efficiency. The non-contact inspection design using a laser and industrial camera enhances inspection accuracy and real-time performance. The laser projects a laser line onto the belt surface, and the industrial camera captures the laser line deformation in real time. When the belt tears, the change in laser line shape can be quickly identified. The anti-slip burr design on the surface of the positioning rollers solves the problem of belt misalignment. The positioning rollers are linked to the drive shaft, driving the belt to rotate stably under the drive of a motor, ensuring controllable belt position during inspection, reducing the risk of false positives and missed negatives, and improving the practicality of the device.

[0028] Example:

[0029] Please see Figure 1-5A belt tear detection device includes a base plate 1, an adjustment mechanism 5 fixedly connected to the upper end of the base plate 1, a positioning plate 2 fixedly connected to the upper part of the adjustment mechanism 5, a detection mechanism 4 fixedly connected to the upper end of the positioning plate 2, four reinforcing plates 3 fixedly connected to the upper part of the adjustment mechanism 5, and the ends of the four reinforcing plates 3 that are close to each other are respectively fixedly connected to the left and right ends of the positioning plate 2. The adjustment mechanism 5 includes a support plate 51, a motor 52 fixedly connected to the upper end of the support plate 51, a positioning component 54 fixedly connected to the output end of a slider 53 through a coupling, an adjustment component 55 slidably connected to the outside of the positioning component 54, and a slider 53 fixedly connected to the lower end of the support plate 51. The inner surface of the slider 53 is slidably connected to the outer surface of the guide rod 555 located on the rear side.

[0030] This solution uses four reinforcing plates 3 to ensure the stability of the connection between the positioning plate 2 and the adjustment mechanism 5. The adjustment mechanism 5 is used to facilitate the positioning of belts of different sizes and drive the belt to rotate. During the rotation of the belt, the detection mechanism 4 can accurately detect the tear on the belt, making it easy to detect the tear in time.

[0031] Please see Figure 2-5 The testing mechanism 4 includes a testing box 41, the lower end of which is fixedly connected to the upper end of the positioning plate 2, a laser 42 fixedly connected to the lower end of the testing box 41, and an industrial camera 43 fixedly connected to the lower end of the testing box 41.

[0032] The adjustment assembly 55 includes a baffle 551, the lower end of which is fixedly connected to the upper end of the base plate 1. A guide groove 552 is provided at the front end of the baffle 551. A second motor 553 is fixedly connected to the right end of the baffle 551. A two-way lead screw 554 is fixedly connected to the output end of the second motor 553 through a coupling. Two guide rods 555 are fixedly connected to the left and right walls of the inner cavity of the baffle 551.

[0033] The positioning component 54 includes two movable blocks 541. The inner surfaces of the two movable blocks 541 are threaded to the outer surface of the bidirectional lead screw 554. The rear end of the movable block 541 on the left side is fixedly connected to the front end of the support plate 51. A second slider 542 is fixedly connected to the lower end of the movable block 541. The inner surfaces of the two second sliders 542 are slidably connected to the outer surface of the guide rod 555 on the front side. A positioning tube 543 is fixedly connected to the upper end of the second slider 542. A drive shaft 544 is rotatably connected to the inner surface of the positioning tube 543. A sliding block 545 is fixedly connected to the outer surface of the drive shaft 544. The outer surfaces of the two sliding blocks 545 are slidably connected to the inner surface of the guide groove 552. A positioning roller 546 is fixedly connected to the outer surface of the drive shaft 544.

[0034] This solution uses motor 553 to rotate the bidirectional lead screw 554. Since the two sections of threads on the outer surface of the bidirectional lead screw 554 are opposite, when the bidirectional lead screw 554 rotates, it drives the two moving blocks 541 to move to both sides simultaneously along the outer surface of the guide rod 555 located on the front side, with the cooperation of the two sliders 542. This allows the two positioning rollers 546 to also move to both sides with the cooperation of the two sliding blocks 545 and the guide groove 552, supporting the belt and facilitating the detection of belts of different lengths. At the same time, the small protrusions on the outer surface of the two positioning rollers 546 facilitate the positioning of the belt, preventing the belt from deviating during the detection process, and making it easier for the device to detect belts of different widths.

[0035] Start motor 52 to rotate drive shaft 544 connected to motor 52. Drive shaft 544 will drive positioning roller 546 located on its outer surface to rotate, so that the belt will rotate under the joint action of the two positioning rollers 546. At this time, a laser line is formed on the belt by the action of laser 42. The image of the laser-irradiated area is captured by industrial camera 43. When the belt is torn, the shape of the laser line will change. This change can be captured by industrial camera 43, thereby realizing accurate detection of belt tear.

[0036] It should be noted that the specific installation methods, circuit connection methods, and control methods of the laser 42, industrial camera 43, motor 2 553, and motor 1 52 in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0037] Working principle: When the device is needed to perform tear detection on a belt, the belt to be tested can be placed on two positioning rollers 546. The small protrusions on the outer surface of the two positioning rollers 546 facilitate the positioning of the belt, preventing the belt from deviating during the test. It also facilitates the testing of belts of different widths. The second motor 553 is started, causing the bidirectional lead screw 554 to rotate under the action of the second motor 553. When the bidirectional lead screw 554 rotates, it drives the two moving blocks 541 to move to both sides simultaneously along the outer surface of the guide rod 555 located on the front side, with the cooperation of the two sliders 542. This allows the two positioning rollers 546 to also move to both sides with the cooperation of the two sliding blocks 545 and the guide groove 552, supporting the belt and facilitating the testing of belts of different lengths.

[0038] The motor 52 located at the upper end of the pallet 51 will also slide to the left along the outer surface of the guide rod 555 located on the rear side with the cooperation of the slider 53. When the belt is supported, the motor 52 is started, which makes the transmission shaft 544 connected to the motor 52 rotate. The transmission shaft 544 will drive the positioning roller 546 located on its outer surface to rotate, so that the belt rotates under the cooperation of the two positioning rollers 546. At this time, a laser line is formed on the belt by the action of the laser 42. The image of the laser-irradiated area is captured by the industrial camera 43. When the belt is torn, the shape of the laser line will change. This change can be captured by the industrial camera 43, thereby realizing the accurate detection of belt tear.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
