Description

Technical Field

[0001] This utility model relates to the field of winding machine testing technology, specifically to a winding machine motor temperature monitoring device. Background Technology

[0002] An aluminum foil coiling machine is a specialized device used to combine two or more sheets of aluminum foil into one coil. Each coiling machine has one edge-breaking fan and one edge-suction fan. To reduce noise, the fans are installed underground in pits covered with sound-insulating panels. Due to limited underground space and the double-layered sound-insulating panels, heat dissipation is poor, making the motor highly susceptible to overheating and burning out, posing a significant safety hazard.

[0003] To ensure equipment safety, monitoring of motor temperature should be increased. Personnel should be able to obtain motor temperature information as they pass through inspection points, thus preventing equipment accidents. Summary of the Invention

[0004] To address the problem of difficulty in detecting fan temperature, this utility model proposes a winding machine motor temperature monitoring device. A detection module is installed on the mounting frame, and a temperature sensor is installed on the detection module to detect the motor temperature. Hardware circuitry is installed on the ground to complete signal processing. The fan temperature is digitally displayed by a controller and display module, which facilitates inspection by staff.

[0005] To achieve the above objectives, this utility model proposes a motor temperature monitoring device for a winding machine. The winding machine includes an edge-breaking fan and an edge-suction fan, both of which include motors. The edge-breaking fan and the edge-suction fan are installed underground, with a sound insulation board between them and the ground. The motor is equipped with a mounting bracket and feet, and the motor is fixed to the feet with bolts. The mounting bracket is a square frame structure, with the bottom end of the mounting bracket extending outward and having bolt holes.

[0006] Two crossbeams are provided on the upper surface of the mounting bracket. The base is fixed to the two crossbeams by bolts. A detection module is provided between the two crossbeams. The detection module includes a mounting beam and a connecting block. The two ends of the mounting beam are fixed to the crossbeams by screws. The connecting block is fixed on the mounting beam. The connecting block has a threaded hole. The direction of the threaded hole is perpendicular to the motor.

[0007] The detection module also includes a temperature sensor and hardware circuitry. The hardware circuitry includes a filter circuit, an amplifier circuit, a controller, and a display module. The temperature sensor includes a probe, which is fixed to a connecting block by threads. The probe is in contact with a motor. The output of the temperature sensor is connected to the filter circuit and then to the controller via the amplifier circuit. The output of the controller is connected to two display modules.

[0008] The hardware circuitry is located on the ground.

[0009] Furthermore, a corrugated tube is provided between the probe and the filter circuit, and the corrugated tube is sleeved on the wire between the probe and the filter circuit.

[0010] Corrugated conduits are used to protect the conductors.

[0011] Furthermore, the mounting beam includes a slide rail, and the connecting block includes a slider, which is slidably connected to the slide rail.

[0012] Because the bottom surface of the motor has an irregular shape with uneven surfaces, a sliding connection structure is adopted to facilitate the installation of the probe by placing the connecting block in a relatively flat position on the bottom of the motor, so that the probe and the motor housing can contact each other and improve the detection accuracy.

[0013] Furthermore, the filtering circuit includes an RC filtering circuit, the output of which is connected to an amplifier circuit, the amplifier circuit includes an LM358 module, and the output of which is connected to a controller.

[0014] The output signal of the temperature sensor is processed by setting up an RC filter circuit and an amplifier circuit to ensure the accuracy of long-distance signal transmission.

[0015] Furthermore, the display module includes an LED display, which is communicatively connected to the controller;

[0016] The controller is equipped with a reset circuit.

[0017] The LED display, controller, RC filter circuit, and amplifier circuit are combined using an embedded circuit structure, which simplifies circuit wiring and facilitates maintenance.

[0018] Furthermore, the hardware circuit also includes a power supply module.

[0019] Furthermore, the hardware circuit is provided with a housing, which is a square structure with flanges on both sides and bolt holes on each of the two flanges;

[0020] The bottom of the housing has a cable outlet, and the housing has a cover.

[0021] The housing has elongated windows corresponding to the two display modules.

[0022] The enclosure facilitates the installation of hardware circuitry.

[0023] The beneficial effects of this utility model through the above technical solution are as follows:

[0024] This invention enables temperature detection of the motor. A detection module is installed on the mounting bracket, equipped with a temperature sensor to directly detect the temperature of the motor housing. The hardware circuitry is placed on the ground, and the fan temperature is digitally displayed via a controller and display module. This greatly facilitates the intuitive and convenient acquisition of motor temperature data by personnel at inspection points, effectively avoiding the lack of motor temperature monitoring caused by the inconvenience of traditional detection methods, and providing strong protection for the safe operation of the equipment.

[0025] Considering the irregular shape of the motor's bottom surface, the mounting beam and connecting block adopt a sliding connection structure, which allows for flexible adjustment of the connecting block's position. This ensures that the probe is installed at a relatively flat location on the bottom of the motor, guaranteeing full contact between the probe and the motor housing, thereby significantly improving the accuracy of temperature detection.

[0026] The output of the temperature sensor is connected to a filter circuit and an amplifier circuit in sequence, which can effectively process the signal output by the temperature sensor and ensure accuracy during long-distance signal transmission. Attached Figure Description
