Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyor state detection, and particularly relates to a dust cleaning component of a belt tearing detection device. Background Art

[0002] Belt conveyors are currently widely used in various links of modern industrial production, such as packaging, transportation, etc. During the operation of the belt conveyor, due to factors such as aging and abnormal working conditions, the belt of the belt conveyor may have tearing problems. Specifically, belt tearing can be attributed to the following reasons: 1) Scratching by foreign objects; 2) Belt deviation; 3) Material jamming; 4) Improper installation of auxiliary equipment; 5) Tearing caused by blocked materials; 6) Tearing caused by the dropping of intermediate rollers; 7) Tearing at the head; 8) Tearing caused by faults of conveyor components. No matter what causes the belt to tear, it will eventually lead to material leakage, equipment damage, and even more serious safety accidents.

[0003] It is crucial for the safe operation of the belt conveyor system to detect the state of the belt of the belt conveyor in time to discover belt tearing problems and make timely shutdown treatments. In the prior art, belt tearing detection methods rely on manual inspections or contact sensors. The manual inspection method mainly relies on active observation, while contact sensors usually detect changes in the tension of the belt conveyor. The aforementioned detection means have problems such as untimely detection and low accuracy. Therefore, it is necessary to develop and design a new type of belt tearing detection means to solve the aforementioned technical problems. Projecting a "one"-shaped laser light band on the surface of the belt and photographing the position where the laser light band is located to obtain an image, and judging whether the belt has a tearing problem by whether the laser light band in the image remains straight is a potentially effective solution. This solution can solve the disadvantages of not being able to detect problems in time during manual inspections and the problem of inaccurate detection of contact sensors. However, the operating scenario of the belt conveyor is usually a multi-dust scenario, and the environment where the tearing detection device is located is relatively harsh. If the dust covering the detection device cannot be removed in time, the laser light band cannot be effectively projected and accurate images cannot be obtained.

[0004] In summary, it is necessary to develop and design a dust cleaning component of a belt tearing detection device, which acts on the detection component and ensures the projection effect of the laser light band and obtains accurate images by applying controllable dust cleaning operations.

[0016] In order to further understand the inventive content, features and effects of the present utility model, the following embodiments are given for detailed description.

[0017] Please refer to Figure 1 , the dust cleaning component of the belt tear detection device of the present utility model is applied to a belt tear detection device that projects a laser light band on the surface of the belt and determines whether the belt is torn by taking a picture of the belt image with the laser light band. The belt tear detection device includes a detection component 14 that is lifted and displaced by a lifting drive component. The detection component 14 is located below the return belt of the belt conveyor. The detection component 14 includes a housing, and a laser generator and a camera are installed inside the housing. The laser projection direction of the laser generator and the shooting direction of the camera both face upward. The laser generator projects a "one"-shaped laser light band on the surface of the return belt, and the camera obtains an image of the belt. It is determined whether the belt is torn according to whether the laser light band in the image remains "one"-shaped.

[0018] A transparent cover plate 13 is installed on the top of the detection component 14. The transparent cover plate 13 is selected as a tempered glass plate, which can ensure the structural strength while not affecting the projection of the laser beam and the taking of images. A cable interface is provided at the bottom of the housing for connecting the power supply cable and the signal cable. The laser generator and the camera of the detection component 14 are enclosed inside, so that it can provide a protective effect on the laser generator and the camera.

[0019] The detection component 14 is lifted and displaced by a lifting drive component, so that the height of the laser generator and the camera can be adjusted, that is, the distance between the laser generator and the camera and the return belt can be adjusted.

[0020] As shown in the figure, the lifting drive assembly includes a support column 3 with a guiding strip hole 1 on its side wall. An adjusting screw 5 is installed on the support column 3. An elevating base 4 is provided inside the support column 3. A threaded hole is provided in the middle of the elevating base 4 and the adjusting screw 5 is located in this threaded hole. A guiding screw 2 is also installed on the side of the elevating base 4 and the guiding screw 2 is located in the guiding strip hole 1. The housing of the detection assembly 14 is fixedly connected to the elevating base 4. The upper end of the adjusting screw 5 is provided with a rotating end head. Tools such as a wrench can be used to drive the adjusting screw 5 to rotate by turning the rotating end head. Correspondingly, the elevating base 4 drives the detection assembly 14 to move up or down. Through the cooperation of the guiding screw 2 and the guiding strip hole 1, the elevating base 4 can only move up and down without swinging left and right.

[0021] An installation base plate with installation holes is provided at the bottom of the support column 3. During installation, multiple such Figure 1 shown integral devices are installed and fixed on a bottom frame by bolts, and the bottom frame is installed and fixed on the equipment frame of the belt conveyor by bolts. Therefore, multiple detection devices equipped with dust cleaning components project laser light bands onto different positions on the surface of the upper return belt, and images of the belt surface with laser light bands at different positions are obtained by taking pictures.

[0022] The dust cleaning component acts on the transparent cover plate 13 at the top of the detection assembly 14, including a cleaning mechanism and a blowing mechanism, and is used to controllably provide a dust cleaning effect on the transparent cover plate 13, ensure the cleanliness of the transparent cover plate 13, ensure the projection effect of the laser light band, and obtain accurate detection images.

[0023] The cleaning mechanism includes a cleaning support 7 installed and fixed on the side of the detection assembly 14. A cleaning cylinder 6 is installed on the cleaning support 7. An elastic frame 9 is installed at the end of the piston rod of the cleaning cylinder 6. A cleaning scraper 8 is installed at the front of the elastic frame 9 and the bottom edge of the cleaning scraper 8 contacts the surface of the transparent cover plate 13.

[0024] In this embodiment, the cleaning support 7 is fixedly connected to the side of the detection assembly 14 by screws. The elastic frame 9 is made of an elastic metal plate, and its top is fixedly connected to the end of the piston rod of the cleaning cylinder 6. The cleaning scraper 8 is a strip-shaped rubber plate and is installed and fixed at the front of the elastic frame 9 by a clamping plate 10 and bolts. The elastic frame 9 made of elastic metal plate can generate deformation by itself, avoiding the problem of jamming of the cleaning scraper 8. After the cleaning scraper 8 is worn, it can be disassembled and replaced with a new one.

[0025] The blowing mechanism includes a uniform flow base 11 with an air passage and an air source interface. A uniform flow plate 12 with air jet holes is installed inside the uniform flow base 11, and the compressed air discharged from the air jet holes is directed towards the transparent cover plate 13.

[0026] In this embodiment, the bottom of the flow-equalizing base 11 is fixedly connected to the side of the detection component 14 by screws. The flow-equalizing base 11 has an inclined inner wall. The flow-equalizing plate 12 is fixedly connected to the flow-equalizing base 11 by a plurality of screws and the flow-equalizing plate 12 covers the inner end of the air duct. The compressed air pipeline is connected to the air source interface on the flow-equalizing base 11, and the on-off of the compressed air is controlled by an electromagnetic valve. When the air path is connected, the compressed air is ejected toward the transparent cover plate 13 through the air duct and the air ejection holes of the flow-equalizing plate 12 to blow the dust.

[0027] Generally, the action modes of the cleaning mechanism and the jetting mechanism are as follows: first, jetting cleaning is performed, and then scraping cleaning is performed. In the jetting cleaning stage, the compressed air jets to remove the surface floating dust and large particle materials on the transparent cover plate 13. In the scraping cleaning stage, the scraper further removes the stubborn dust on the transparent cover plate 13. After the two stages, the surface of the transparent cover plate 13 is restored to cleanliness, and then the operation of taking images is started. The dust cleaning operation can be manually triggered through the control of the host computer. After manual triggering, the above-mentioned process of first jetting cleaning and then scraping cleaning is executed. It is also possible to set the time interval of dust cleaning. When the time for the dust cleaning operation is reached, the above-mentioned process of first jetting cleaning and then scraping cleaning is automatically executed.
