Description

Technical Field

[0001] This utility model relates to the field of monitoring device technology, and in particular to an online spectral monitoring device for elements in a conveyor belt. Background Technology

[0002] The online elemental spectral monitoring device for conveyor belts is a device used for elemental analysis of materials on conveyor belts. Among them, the infrared online moisture monitor is a type of online spectral monitoring equipment. The infrared online moisture monitor measures moisture content by utilizing the absorption characteristics of infrared light by substances, and has the following structure:

[0003] 1. Near-infrared probe, used to emit and receive near-infrared light, and to determine moisture content by analyzing the absorption characteristics of infrared light by materials;

[0004] 2. Host monitor, used to display test results and provide a human-machine interface.

[0005] The probe is fixed above the conveyor belt and begins to collect the spectral data of the material on the conveyor belt in real time. Through spectral analysis, the material composition can be monitored in real time to ensure quality control during the production process. As the conveyor belt moves, if the material on the belt accumulates too high, the material is prone to colliding with the probe, which can damage the probe and affect the service life of the equipment. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an online elemental spectral monitoring device for conveyor belts, which solves the technical problem that if the material on the belt accumulates too high, it is easy for the material to collide with the probe, causing damage to the probe and affecting the service life of the equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An online spectral monitoring device for material conveyor belts includes a probe and a main unit display. Below the probe is a limiting mechanism to restrict the height of material on the conveyor belt. The limiting mechanism includes a vertical plate and a scraper plate. The vertical plate is fixedly installed on the lower surface of the probe, and the scraper plate is located at the lower end of the vertical plate. A square nut is provided on the side of the vertical plate near the scraper plate, and a screw is threaded into the internal part of the square nut. The screw is fixedly installed on the outside of the scraper plate. A fixing mechanism for restricting the rotation of the scraper plate is provided on the outside of the vertical plate. The fixing mechanism includes a moving groove, a limiting plate, and a limiting groove. The moving groove is located on the outside of the vertical plate. One end of the limiting plate is slidably connected to the inside of the moving groove, and the limiting groove is located on the outside of the scraper plate. The other end of the limiting plate is engaged with the inside of the limiting groove to restrict the rotation of the scraper plate.

[0009] The scraper plate has a mounting groove on one side corresponding to the square nut, and the square nut is snapped into the inside of the mounting groove. The lower surface of the scraper plate has a through hole, and the screw is connected to the square nut through the through hole.

[0010] Preferably, a threaded rod is fixedly installed inside the movable groove, a threaded sleeve is threadedly connected to the outside of the threaded rod, a limiting plate is slidably connected to the outside of the threaded rod, and a washer is movably sleeved on the outside of the threaded rod, with the washer located between the threaded sleeve and the limiting plate.

[0011] Preferably, the threaded sleeve has a handle on its exterior, and several protrusions are fixedly installed on the exterior of the threaded sleeve, with the handle snapped onto the exterior of the protrusions.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The scraper plate is connected to the vertical plate via a screw and a square nut. The detachable connection facilitates the installation of scraper plates of different lengths to accommodate conveyor belts of different widths. The scraper plate is used to level materials and, in conjunction with the vertical plate, limits the material accumulation height, ensuring that the material plane passing under the probe is always directly below the probe. This prevents the material from being too high and directly contacting the probe, thus preventing collisions when the material accumulates too high and avoiding damage to the probe due to external forces, thereby extending the probe's service life.

[0014] Second, the threaded rod, threaded sleeve, and washer can restrict the upward movement of the limiting plate, thereby ensuring the stability of the connection between the limiting plate and the limiting groove, and thus ensuring the stability of the connection between the scraper plate and the vertical plate.

[0021] This application provides an online elemental spectral monitoring device for conveyor belts, which effectively solves the technical problem that when the material on the belt is piled up too high, the material is prone to colliding with the probe, causing damage to the probe and affecting the service life of the equipment.

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that if the material on the belt accumulates too high, the material is prone to colliding with the probe, causing damage to the probe and affecting the service life of the equipment. The overall idea is as follows:

[0024] To address the problems existing in the prior art, this utility model provides an online spectral monitoring device for material conveyor belts, including a probe 1 and a main display 16. The probe 1 is the core component of the spectral monitoring device, responsible for real-time acquisition of the spectral data of the material on the conveyor belt. A limiting mechanism for restricting the height of the material on the conveyor belt is provided below the probe 1. The limiting mechanism includes a vertical plate 2 and a scraper plate 3. The vertical plate 2 is fixedly installed on the lower surface of the probe 1, and the scraper plate 3 is located at the lower end of the vertical plate 2. A square nut 4 is provided on the side of the vertical plate 2 near the scraper plate 3. A screw rod 5 is connected to the internal thread of the square nut 4 and is fixedly installed on the outside of the scraper plate 3.

[0025] The vertical plate 2 is provided with a fixing mechanism for limiting the rotation of the scraper plate 3. The fixing mechanism includes a moving groove 6, a limiting plate 7 and a limiting groove 8. The moving groove 6 is opened on the outside of the vertical plate 2. One end of the limiting plate 7 is slidably connected to the inside of the moving groove 6. The limiting plate 7 is L-shaped. The limiting groove 8 is opened on the outside of the scraper plate 3. The other end of the limiting plate 7 is engaged in the inside of the limiting groove 8 and is used to limit the rotation of the scraper plate 3.

[0026] The scraper plate 3 has a mounting groove 9 on one side corresponding to the square nut 4. The square nut 4 is snapped into the inside of the mounting groove 9. The square nut 4 is detachable for easy replacement. The lower surface of the scraper plate 3 has a through hole 10, which communicates with the inside of the mounting groove 9. The screw 5 is connected to the square nut 4 through the through hole 10.

[0027] A threaded rod 11 is fixedly installed inside the movable groove 6, and a limiting plate 7 is slidably connected to the outside of the threaded rod 11. A threaded sleeve 12 is threadedly connected to the outside of the threaded rod 11.

[0028] A washer 13 is movably fitted onto the outside of the threaded rod 11. The washer 13 is located between the threaded sleeve 12 and the limiting plate 7. The washer 13 increases the contact area and reduces the probability of the threaded sleeve 12 rotating. A handle 14 is provided on the outside of the threaded sleeve 12. The handle 14 is composed of a cuboid plate and a concave plate. Several protrusions 15 are fixedly installed on the outside of the threaded sleeve 12. The handle 14 is snapped onto the outside of the protrusions 15. The handle 14 is used to rotate the threaded sleeve 12, improving the convenience of operation. After rotation, the connection between the handle 14 and the protrusions 15 is released.

[0029] Scraper plate 3 and vertical plate 2: Scraper plate 3 is used to scrape the material and, in cooperation with vertical plate 2, limits the material accumulation height, ensuring that the material plane passing under probe 1 is always directly below probe 1, avoiding direct contact between the material and probe 1 when the material is too high, preventing collision with probe 1 when the material is too high, avoiding damage to probe 1 due to external force, and extending the service life of probe 1.

[0030] Screw 5 and square nut 4: The scraper plate 3 is connected to the screw 5 and the square nut 4 on the vertical plate 2. The detachable connection makes it easy to install scraper plates 3 of different lengths to adapt to conveyor belts of different widths.

[0031] Limiting plate 7 and limiting groove 8: The connection between limiting plate 7 and limiting groove 8 effectively prevents the rotation of scraper plate 3, thereby ensuring the scraping effect of scraper plate 3.

[0032] Threaded rod 11, threaded sleeve 12 and washer 13: Threaded rod 11, threaded sleeve 12 and washer 13 can restrict the upward movement of the limiting plate 7, thereby ensuring the stability of the connection between the limiting plate 7 and the limiting groove 8, and thus ensuring the stability of the connection between the scraper plate 3 and the vertical plate 2.

[0033] Working principle:

[0034] First, before the probe 1 is installed above the conveyor belt, insert the square nut 4 into the installation groove 9, and then thread the screw 5 on the outside of the scraper plate 3 to the square nut 4 through the through hole 10 until the scraper plate 3 is in contact with the lower surface of the vertical plate 2. At this time, move the limiting plate 7 downward so that one end of the limiting plate 7 is inserted into the limiting groove 8 to restrict the rotation of the scraper plate 3.

[0035] In the second step, the handle 14 is engaged with the corresponding protrusion 15 to rotate the threaded sleeve 12, causing the threaded sleeve 12 to move downwards until it pushes the washer 13 to fit tightly against the upper surface of the limiting plate 7. At this point, the limiting plate 7 is fixed and cannot move. The probe 1 is then fixed above the conveyor belt, and the material spectral data on the conveyor belt is collected in real time. Through spectral analysis, the material composition can be monitored in real time to ensure quality control during the production process. As the conveyor belt moves, the scraper plate 3 can scrape the material to ensure that the material plane passing under the probe 1 is always directly below the probe 1, avoiding direct contact between the material and the probe 1 when the material is too high, and preventing collision with the probe 1 when the material is piled up too high.

[0036] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
