[0002] In powder screening workshops, ultrasonic vibrating screens are commonly used to screen powders. Due to various reasons, the transducers of the vibrating screen are prone to failure, causing the vibrating screen to lose its screening effect.

Moreover, it affects the production progress and is not easy to detect. Therefore, there is an urgent need for a technical solution that can prevent the accumulation of material in the screen body after the transducer fails. Utility Model Content

Detailed Implementation

[0047] To enhance understanding of this utility model, it will be described in further detail below with reference to the accompanying drawings and embodiments. These embodiments are only used to explain this utility model and do not limit the scope of protection of this utility model.

[0048] Please refer to Figures 1 to 4The present invention provides an ultrasonic transducer measurement and control module, comprising: a power socket 10, a power switch 11, a power module 12, a first current measuring and control meter 13, a first relay 14, a first socket 15, and a second socket 16.

[0049] The power socket 10 is electrically connected to the input terminal of the power switch 11;

[0050] The output terminal of the power switch 11 is electrically connected to the input terminal of the power module 12, the power terminal and signal detection input terminal of the first current measuring and control meter 13, and the first switch input terminal and the second switch input terminal of the first relay 14, respectively.

[0051] The first output terminal of the power module 12 is electrically connected to the first switch control terminal of the first current measuring and control meter 13, and its second output terminal is electrically connected to the control output terminal of the first relay 14.

[0052] The signal detection output terminal of the first current measuring and control meter 13 is electrically connected to the first switch input second terminal of the first relay 14, and its first switch control second terminal is electrically connected to the control input terminal of the first relay 14.

[0053] The first switch output terminal of the first relay 14 is electrically connected to the first socket 15, and its second switch output terminal is electrically connected to the second socket 16.

[0054] The first socket 15 is used to supply power to the first ultrasonic transducer control box;

[0055] The second socket 16 is used to supply power to the first material conveyor;

[0056] Wherein, after the power switch 11 is closed, the first current measuring and control meter 13 monitors the real-time operating current of the power line where the first ultrasonic transducer control box is located. When the real-time operating current is less than the preset threshold current, it controls the first switch to disconnect the first terminal and the second terminal so that the first relay 14 is de-energized for protection.

[0057] In this embodiment, both the power socket 10 and the power switch 11 can be conventional models. The power socket 10 includes a live wire (L) interface, a neutral wire (N) interface, and a ground wire interface, with the ground wire interface connected to the ground wire interfaces of the first socket 15 and the second socket 16. The power module 12 can be a conventional switching power supply (such as an AC220V to DC12V power supply), and its output terminals include a live wire (L) terminal and a neutral wire (N) terminal. The power module 12 provides operating voltage for the relay control circuit containing the control input and control output terminals of the first relay 14. The first current measuring and control meter 13 can be a smart current measuring and control meter of model CS7940T-N, which can both detect the current magnitude and provide an interface with on or off functions. The first switch control terminal and the second terminal of the first current measuring and control meter 13 have two states: on and off. The default is the on state, providing switch control for the relay control circuit of the first relay 14. The power terminal of the first current measuring and control meter 13 is used to connect to the working power supply, and its signal detection input and signal detection output terminals serve as signal detection terminals for detecting the current magnitude. The first relay 14 can be a conventional relay with multiple inputs and outputs, controlling whether the first socket 15 and the second socket 16 are powered. The first socket 15 and the second socket 16 can be conventional electrical sockets, such as three-prong sockets. The first ultrasonic transducer control box is a conventional ultrasonic transducer control box used to control the corresponding ultrasonic transducer. The first material conveyor is a conventional material conveyor. In one specific embodiment, when the corresponding ultrasonic transducer fails, the current of the first ultrasonic transducer control box is less than 0.2A. The first current meter 13 can be set to 0.2A as a preset threshold current. The first socket 15 is connected to the first ultrasonic transducer control box, and the second socket 16 is connected to the first material conveyor. The power socket 10 is connected to an AC 220V power supply. When the power switch 11 is closed, the first ultrasonic transducer control box and the first material conveyor are powered on. The first current meter 13 monitors the current of the first ultrasonic transducer control box; when the corresponding ultrasonic transducer fails, the current of the first ultrasonic transducer control box is below 0.2A. The first current measuring and control meter 13 detects a change in current, which is lower than the preset current value, i.e., the preset threshold current (0.2A). It outputs a control signal to drive the first relay 14 to cut off the power supply to the first ultrasonic transducer control box and the first material conveyor, thereby stopping the supply of materials to avoid damage to the screen.

[0058] In one possible implementation, a third socket 17 for powering the audible and visual alarm 23 is also included;

[0059] The second switch of the first current measuring and control meter 13 is electrically connected to the first output terminal of the power module 12, and its second switch is electrically connected to the first terminal of the third socket 17.

[0060] The second terminal of the third socket 17 is electrically connected to the second output terminal of the power module 12.

[0061] In this embodiment, the third socket 17 can be a conventional two-hole socket. The power module 12 provides power to the audible and visual alarm 23. In specific implementation, the first current measuring and control meter 13 detects a current change that is lower than the preset current value, i.e., the preset threshold current (0.2A), and outputs a control signal to start the audible and visual alarm 23, providing the staff with a sound and light fault notification signal. At the same time, the signal drives the first relay 14 to cut off the power to the first ultrasonic transducer control box and the first material conveyor, stopping the material supply to prevent damage to the screen. Upon receiving the audible and visual fault signal notification, the staff turns off the power switch 11 to deactivate the alarm and inspects the ultrasonic transducer until production is restored.

[0062] In one possible implementation, it also includes a second current measuring and control meter 18, a second relay 19, a fourth socket 20, and a fifth socket 21;

[0063] The output terminal of the power switch 11 is also electrically connected to the power terminal and signal detection input terminal of the second current measuring and control meter 18, and the first switch input terminal and the second switch input terminal of the second relay 19, respectively.

[0064] The first output terminal of the power module 12 is electrically connected to the first switch control terminal of the second current measuring and controlling meter 18, and its second output terminal is electrically connected to the control output terminal of the second relay 19.

[0065] The signal detection output terminal of the second current measuring and control meter 18 is electrically connected to the first switch input second terminal of the second relay 19, and its first switch control second terminal is electrically connected to the control input terminal of the second relay 19;

[0066] The first switch output terminal of the second relay 19 is electrically connected to the fourth socket 20, and its second switch output terminal is electrically connected to the fifth socket 21;

[0067] The fourth socket 20 is used to supply power to the second ultrasonic transducer control box.

[0068] The fifth socket 21 is used to supply power to the second material conveyor.

[0069] In this embodiment, the ground wire interface of the power socket 10 is connected to the ground wire interfaces of the fourth socket 20 and the fifth socket 21. The power module 12 provides operating voltage to the relay control circuit where the control input and control output terminals of the second relay 19 are located. The second current measuring and control meter 18 can be the same model as the first current measuring and control meter 13, such as a smart current measuring and control meter of model CS7940T-N, which can both detect the current magnitude and provide an interface with on or off functions. The first switch control terminal of the second current measuring and control meter 18 has two states: on and off, with the default being the on state, providing switch control for the relay control circuit of the second relay 19. The power supply terminal of the second current measuring and control meter 18 is used to connect to the working power supply, and its signal detection input terminal and signal detection output terminal serve as signal detection terminals for detecting the current magnitude. The second relay 19 can be the same model as the first relay 14, such as a conventional relay with multiple inputs and outputs, controlling whether the fourth socket 20 and the fifth socket 21 are powered. The fourth socket 20 and the fifth socket 21 can be conventional power sockets, such as three-prong sockets. The second ultrasonic transducer control box is a conventional ultrasonic transducer control box used to control the corresponding ultrasonic transducer. The second material conveyor is a conventional material conveyor. In one specific embodiment, when the corresponding ultrasonic transducer fails, the current of the second ultrasonic transducer control box is less than 0.2A. The second current meter 18 can be set to 0.2A as a preset threshold current. The fourth socket 20 is connected to the second ultrasonic transducer control box, and the fifth socket 21 is connected to the second material conveyor. When the power switch 11 is closed, the second ultrasonic transducer control box and the second material conveyor are powered on and working. The second current meter 18 monitors the current of the second ultrasonic transducer control box. When the corresponding ultrasonic transducer fails, the current of the second ultrasonic transducer control box is lower than 0.2A. The second current measuring and control meter 18 detects a change in current. When the current is lower than the preset current value, i.e. the preset threshold current (0.2A), it outputs a control signal to drive the second relay 19, which cuts off the power supply to the second ultrasonic transducer control box and the second material conveyor, stopping the supply of material to avoid damage to the screen. In this way, the two sets of powder screening equipment can be controlled simultaneously.

[0070] In one possible implementation, the second switch control first terminal of the second current meter 18 is electrically connected to the first output terminal of the power module 12, and its second switch control second terminal is electrically connected to the first terminal of the third socket 17.

[0071] In this embodiment, the second current measuring and control meter 18 can trigger the audible and visual alarm 23. In practice, when the second current measuring and control meter 18 detects a current change below a preset current value (i.e., a preset threshold current of 0.2A), it outputs a control signal, causing the audible and visual alarm 23 to activate. This provides the operator with a sound and light fault notification signal. Simultaneously, the signal drives the second relay 19 to cut off the power to the second ultrasonic transducer control box and the second material conveyor, stopping the material supply to prevent damage to the screen. Upon receiving the audible and visual fault signal, the operator turns off the power switch 11 to deactivate the alarm and inspects the corresponding ultrasonic transducer until production is restored.

[0072] This utility model also provides an ultrasonic transducer measurement and control box, including a box body 22 and an ultrasonic transducer measurement and control module as described above;
