Description

Technical Field

[0001] This utility model relates to the field of automatic material stop and machine shutdown technology, specifically to an automatic material stop and machine shutdown device. Background Technology

[0002] A conveyor is a highly efficient and continuous mechanical device for transporting materials. It is widely used in industrial production and logistics. It drives components such as conveyor belts, chains, or rollers to circulate through a transmission device, realizing the directional movement of bulk materials or packaged goods. Its core advantages are high degree of automation, large transport capacity, stable operation, and strong adaptability. It can be designed as a horizontal, inclined, or vertical layout according to needs and is equipped with sorting, weighing, and other modules. It is a key piece of equipment in modern assembly line operations and intelligent warehousing systems, effectively improving material flow efficiency and production flexibility.

[0003] However, in the current non-metallic mineral storage and transportation system, the start-up and shutdown operations rely on manual judgment and linkage with the DCS system. The shutdown sequence of upstream and downstream equipment depends on manual setting. Once an execution error occurs, it will lead to material accumulation or equipment idling. The "stop when material is empty" control mechanism is imperfect. Long conveyor belts are not equipped with detection devices, resulting in large signal fluctuations and unreasonable shutdown time settings. It is impossible to automatically trigger shutdown according to the target tonnage of the ship, requiring manual intervention, which is labor-intensive and has a low fault tolerance rate. Therefore, we need an automatic material stop shutdown device. Utility Model Content

[0008] Preferably, the first hinge plate and the second hinge plate form a hinge structure through a hinge shaft, and one end of the hinge shaft passes through the inner wall at the intersection of the first hinge plate and the second hinge plate.

[0009] Preferably, the transmission component includes a motor, which is disposed on one side of the fixed frame. The output shaft of the motor is fixedly connected to a first belt shaft via a coupling. A second belt shaft is rotatably connected to the inner wall of the fixed frame. A first pulley is fixedly connected to one end of the second belt shaft. A synchronous belt is wound around the outer wall of the first pulley. A third belt shaft is rotatably connected inside the transmission device. A second pulley is fixedly connected to one end of the third belt shaft.

[0010] Preferably, the motor forms a transmission structure with the main conveyor belt through the first belt shaft, and the output shaft of the motor passes through one side of the fixed frame and is fixedly connected to one end of the first belt shaft, and the outer wall of the first belt shaft is connected to the inner wall of the main conveyor belt.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the scheme of this application:

[0015] 1. To address the issues of manual intervention required for start / stop when materials accumulate on the main conveyor belt in existing technologies, and the lack of automatic detection and protection mechanisms, this application proposes a mechanical pressure sensing device consisting of a fixed plate, a hinge shaft, a slider, and a spring. When materials accumulate, the fixed plate is pressed down, and the hinge shaft drives the first and second hinge plates to move in opposite directions, causing the slider to compress the spring along the guide protrusion. Finally, the automatic stop is achieved by triggering the button via the push rod. When the material is uniform, the spring resets, causing all components to return to their initial state, thus realizing real-time monitoring of material accumulation and one-button start / stop linkage.

[0016] 2. To address the problem in existing technologies where material accumulation or transmission interruption occurs when one conveyor stops due to the lack of a synchronous linkage mechanism, this application proposes a core transmission structure that drives the main conveyor belt with a motor. This structure utilizes the first and second belt shafts to achieve linear power transmission. Simultaneously, a synchronous belt connects the first and second pulleys, forming a single-motor, multi-stage linkage system. This design ensures that the main conveyor belt and the conveying device operate synchronously during start-up and shutdown, preventing material jamming caused by power delays or interruptions, and significantly improving transmission stability and efficiency.

A protrusion 402 is fixedly connected to the top of the positioning frame 401, a button 403 is fixedly connected to the top of the positioning frame 401, a fixing block 404 is fixedly connected to the top of the fixed frame 1, a spring 405 is fixedly connected to one side of the fixing block 404, a slider 406 is fixedly connected to one end of the spring 405, a first hinge plate 407 is hinged to the top of the slider 406, a hinge shaft 408 is movably connected to the inner wall of the first hinge plate 407, a second hinge plate 409 is movably connected to the outer wall of the hinge shaft 408, and a connecting block is fixedly connected to the outer wall of the hinge shaft 408. 410. A fixed plate 411 is fixedly connected to the top of the connecting block 410, and a top rod 412 is fixedly connected to the bottom of the connecting block 410. When material accumulates on the main conveyor belt 2, it applies downward pressure to the fixed plate 411, which pushes the connecting block 410 downward. This causes the connecting block 410 to move the hinge shaft 408 downward. When the hinge shaft 408 moves downward, it pushes the slider 406 by moving the first hinge plate 407 and the second hinge plate 409 in opposite directions. The slider 406 moves under the guidance of the protrusion 402. When the slider 406 moves, it squeezes the spring 405, which causes the connecting block 410 to move the top rod 412 downward. When the top rod 412 moves downward, it pushes the button 403 to achieve one-button start and stop. When the material on the main conveyor belt 2 is uniform, the spring 405 resets and pushes the slider 406 back to its initial position.

[0025] Further as Figure 3 As shown, the slider 406 forms an elastic structure with the fixed block 404 via the spring 405, and the spring 405 is disposed between the slider 406 and the fixed block 404. The slider 406 can compress the spring 405 when it moves.

The inner diameter of the groove at the bottom of the slider 406 matches the outer diameter of the protrusion 402. The inner wall of the groove at the bottom of the slider 406 fits against the outer wall of the protrusion 402.

Through the hinge shaft 408, when the hinge shaft 408 moves downward, it can push the slider 406 to move in opposite directions to the first hinge plate 407 and the second hinge plate 409.

By starting the motor 501, materials are fed to the loading point 3 via external equipment. By starting the motor 501, the output shaft of the motor 501 rotates, which drives the first belt shaft 502 to rotate. When the first belt shaft 502 rotates, it drives the main conveyor belt 2 to rotate. When the main conveyor belt 2 rotates, it drives the second belt shaft 503 to rotate. When the second belt shaft 503 rotates, it drives the first pulley 504 to rotate. When the first pulley 504 rotates, it drives the second pulley 506 via the synchronous belt 505. When the second pulley 506 rotates, it drives the third belt shaft 507 to rotate. The third belt shaft 507 drives the conveyor device 6 to perform transmission work.

[0029] Further as Figure 5 As shown, the motor 501 forms a transmission structure with the main conveyor belt 2 through the first belt shaft 502, and the output shaft of the motor 501 passes through one side of the fixed frame 1 and is fixedly connected to one end of the first belt shaft 502. The outer wall of the first belt shaft 502 is connected to the inner wall of the main conveyor belt 2.

By means of the second pulley 506, when the second pulley 506 rotates, it drives the third belt shaft 507 to rotate, which in turn drives the transmission device 6 to perform transmission work.

[0032] Working principle: Material is fed into the feeding point 3 by external equipment. Starting the motor 501 causes its output shaft to rotate, driving the first belt shaft 502 to rotate. The rotation of the first belt shaft 502 drives the main conveyor belt 2 to rotate, which in turn drives the second belt shaft 503 to rotate. The rotation of the second belt shaft 503 drives the first pulley 504 to rotate. The rotation of the first pulley 504, via the synchronous belt 505, drives the second pulley 506. The rotation of the second pulley 506 drives the third belt shaft 507 to rotate, which in turn drives the conveying device 6 for transmission. When the material on the main conveyor belt 2... When materials accumulate, applying downward pressure to the fixed plate 411 causes the fixed plate 411 to push the connecting block 410 downward, which in turn causes the connecting block 410 to drive the hinge shaft 408 downward. When the hinge shaft 408 moves downward, it causes the first hinge plate 407 and the second hinge plate 409 to move in opposite directions, pushing the slider 406. The slider 406 moves under the guidance of the protrusion 402. When the slider 406 moves, it compresses the spring 405, which causes the connecting block 410 to drive the top rod 412 downward. When the top rod 412 moves downward, it pushes the button 403 to achieve one-button start and stop. When the material on the main conveyor belt 2 is uniform, the spring 405 resets and pushes the slider 406 back to its initial position.
