Technical Field

[0001] This utility model relates to the field of bulk material conveying machinery technology, specifically to an intelligent constant pressure belt cleaning device. Background Technology

[0002] The surface of the conveyor belt of a belt conveyor often has materials, impurities, and dust adhering to it, which requires the use of a cleaner to clean it.

[0003] Currently, existing sweepers, such as scraper-type and rotary sweepers, generally have the following defects:

[0004] 1) The cleaning pressure decreases as the blade wears down, resulting in a short-lasting effect;

[0005] 2) Excessive pressure or excessively hard blade material can easily damage the belt;

[0006] 3) The cleaning process can easily generate dust, which pollutes the environment.

[0007] Therefore, we propose an intelligent constant pressure belt cleaning device. Utility Model Content

[0008] The purpose of this invention is to provide an intelligent constant pressure belt cleaning device, which has the advantages of constant pressure, belt protection and environmental protection, and solves the common defects of existing cleaners.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an intelligent constant pressure belt cleaning device, comprising:

[0010] The casing frame, PLC controller, drive motor, adjusting sleeve, and belt rollers;

[0011] The lower end of the cover frame is provided with a discharge port, and the inner side of the discharge port is provided with a baffle plate. Dust collection ports are provided at both ends of one side of the cover frame.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] 1.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The components of this application, including the housing frame 1, dust collection port 101, discharge port 102, PLC controller 2, drive motor 3, rotating shaft 301, adjusting sleeve 4, swing arm 401, pressure sensor 402, composite corrosion-resistant blade 403, mounting block 5, connecting block 501, electric push rod 502, belt roller 6, and conveyor belt 601, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0032] Example 1

[0033] Please see Figures 1-4 As shown, this utility model provides a technical solution: an intelligent constant pressure belt cleaning device, comprising:

[0034] 1. Cover frame; 2. PLC controller; 3. Drive motor; 4. Adjusting sleeve; 6. Belt roller;

[0035] The lower end of the cover frame 1 is provided with a discharge port 102, and the inner side of the discharge port 102 is provided with a baffle plate. Dust collection ports 101 are provided at both ends of one side of the cover frame 1.

[0036] The PLC controller 2 is installed at the upper end of the housing frame 1;

[0037] Among them, the drive motor 3 is installed on the upper end of the cover frame 1, and the output end of the drive motor 3 is fixedly connected to the rotating shaft 301 located on the upper inner side of the cover frame 1.

[0038] Among them, the adjusting sleeve 4 is located on the outer surface of the rotating shaft 301, and the top of the adjusting sleeve 4 is fixed with a swing arm 401. One end of the swing arm 401 is provided with a composite corrosion-resistant blade 403, and a pressure sensor 402 is provided between the composite corrosion-resistant blade 403 and the swing arm 401.

[0039] The belt roller 6 has a conveyor belt 601 on its outer side, and the surface of the conveyor belt 601 is in contact with the cutting edge of the composite corrosion-resistant blade 403.

[0040] The output of PLC controller 2 is electrically connected to the input of drive motor 3 via a wire, and the output of pressure sensor 402 is electrically connected to the input of PLC controller 2 via a wire.

[0041] This technical solution involves: The casing frame 1 is securely installed at a suitable position on the return section of the conveyor belt, ensuring good contact between the composite corrosion-resistant blade 403 and the surface of the conveyor belt 601. The dust collection port 101 is reliably connected to the central dust removal system or an independent dust removal fan in the factory area via a pipeline, ensuring negative pressure suction capability. The PLC controller 2, drive motor 3, pressure sensor 402, and electric push rod 502 are correctly wired according to the electrical drawings and connected to the power supply. On the human-machine interface (such as a touch screen) of the PLC controller 2, the initial working parameters are set: Constant pressure value: Based on the belt material, running speed, and characteristics of the adhered material, an optimal cleaning pressure (e.g., 150-400N) is set. This is the feedback target value of the pressure sensor 402. The setting is also used to determine the range at which the drive motor 3 will start for angle fine-tuning to avoid frequent operation.

[0042] Next, the PLC controller 2 first controls the drive motor 3 to slowly rotate the swing arm 401, so that the composite corrosion-resistant blade 403 gradually contacts the conveyor belt 601. When the pressure value detected by the pressure sensor 402 reaches the preset constant pressure value, the PLC controller 2 locks the angle of the drive motor 3. During operation, the pressure sensor 402 continuously monitors the pressure. When it detects that the pressure is lower than the set value due to blade wear, the PLC immediately sends a signal to the drive motor 3, so that it rotates slightly by an angle, pushing the swing arm 401 to make the composite corrosion-resistant blade 403 further close to the conveyor belt 601 until the pressure returns to the set value, completing one automatic wear compensation. During the entire cleaning process, the negative pressure dust removal system works continuously, sucking away the dust in the cover frame 1 through the dust collection port 101.

[0043] Regularly (e.g., every shift or daily), check the pressure history curve and blade compensation count through the PLC monitoring interface to assess blade wear. Regularly (e.g., monthly), stop the machine to check the remaining thickness of the composite corrosion-resistant blade 403. Replace it before it wears to the safety limit (which can be done through the cumulative compensation stroke warning set by the PLC). Regularly clean the inside of the housing and check the lubrication of each moving part (e.g., the rotating shaft 301 and the electric push rod 502). If necessary, two or more sets of devices can be arranged to be used simultaneously on the surface of the conveyor belt 601. In this way, the device can be integrated into the belt conveyor as a highly intelligent, stable and reliable subsystem, providing a strong guarantee for continuous, efficient and clean production.

[0044] Example 2

[0045] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, the composite corrosion-resistant blade 403 is composed of a base layer, a reinforcing layer and a wear-resistant layer, wherein the base layer is a highly elastic polyurethane, the reinforcing layer is an aramid fiber fabric, and the wear-resistant layer is a polyurethane composite material containing silicon carbide particles.

[0046] This technical solution utilizes a composite corrosion-resistant blade (403) with a highly elastic polyurethane base layer that provides excellent cushioning and fit. The aramid fiber reinforcement layer ensures the blade remains resistant to deformation under constant pressure, maintaining a stable cleaning angle. The silicon carbide wear-resistant layer, while ensuring sharpness, is carefully designed with a hardness lower than the belt surface layer, creating a "soft contact, strong cleaning" effect. This dual protection significantly extends the service life of both the belt and the blade itself.

[0047] Example 3

[0048] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a connecting block 501 is fixed to one end of the outer surface of the adjusting sleeve 4, and a mounting block 5 is fixed to one end of the outer surface of the rotating shaft 301. An electric push rod 502 is mounted on one side of the mounting block 5, and the extended end of the electric push rod 502 is fixedly connected to the mounting block 5. At the same time, the input end of the electric push rod 502 is electrically connected to the output end of the PLC controller 2 through a wire.

[0049] This technical solution: By setting up the mounting block 5, the connecting block 501, and the electric push rod 502, the PLC controller 2 controls the electric push rod 502 to drive the adjusting sleeve 4, the swing arm 401, and the composite corrosion-resistant blade 403 to move laterally along the width direction of the conveyor belt 601. This ensures that the cleaning range covers the entire working surface of the conveyor belt 601. This design can adapt to belts of different widths and can compensate for uneven wear of the blades in the width direction, achieving cleaning without dead angles.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
