[0002] Material suction machine is widely used in industrial automation field, especially in material conveying, processing and production line automation. As an important part of material suction machine, blanking detection is widely used in material proportioning and conveying, warehouse management and production line automation operation.

[0003] In the blanking work of material suction machine, it is required to accurately judge whether the material reaches the specified position or whether the blockage occurs, and the change of the material can be quickly responded, and the alarm or control signal is sent in time, so that the photoelectric eye detection mode is often used in the material suction machine, which is a kind of non-contact sensor technology, using light source emitter (such as light emitting diode LED) to emit light beam, the light beam is focused through lens system and projected on the detected object. When the material falls and blocks the light beam, the light is blocked, resulting in the decrease or disappearance of the light intensity received by the receiver (such as photoresistor, photodiode or phototransistor). According to the change of the light signal received by the receiver, the photoelectric eye can judge whether the material exists or whether it reaches the predetermined position, so as to trigger the corresponding control signal. Although the photoelectric eye detection mode can complete the detection of blanking, when the material color is dark or the surface is reflective, the change of the light intensity received by the receiver may not be obvious, thereby affecting the accuracy of detection. And because the photoelectric eye is exposed to harsh working environment for a long time, its light source emitter and receiver are easy to be contaminated and damaged. Therefore, the photoelectric eye needs to be cleaned and maintained regularly, which increases the maintenance cost of the equipment. CONTENT OF THE UTILITY MODEL

[0026] In order to further understand the characteristics, technical means and specific purposes and functions achieved by the utility model, the utility model will be described in further detail below in combination with the drawings and specific embodiments.

[0027] Example one: please refer to Figures 1-5The utility model provides a technical scheme: a magnetic ring induction blanking port for blanking detection of a vacuum material suction machine body 2, comprising a material receiving hopper 1 and its external auxiliary feeding equipment 4, and the vacuum material suction machine body 2 is provided with a magnetic ring induction mechanism 3 for detecting blanking.

[0028] The magnetic ring induction mechanism 3 comprises a material discharging assembly 31 for discharging material in the vacuum material suction machine body 2 and an induction assembly 32 for detecting blanking.

[0029] The material discharging assembly 31 comprises a material shielding plate 313 movably arranged in the material receiving hopper 1, and the material shielding plate 313 is externally provided with a magnetic ring switch 314.

The rotation design of the material shielding plate 313 in the connecting seat 312 enables the material shielding plate 313 to quickly respond to the blanking and change the magnetic field state, thereby improving the sensitivity and real-time performance of the detection. At the same time, this design also facilitates the maintenance and replacement of the material shielding plate 313, thereby reducing the maintenance cost of the equipment.

[0032] Further, the magnetic ring switch 314 is specifically arranged on the side of the material shielding plate 313 close to the connecting seat 312. The close cooperation between the magnetic ring switch 314 and the material shielding plate 313 ensures that the magnetic field change can accurately reflect the rotation state of the material shielding plate 313, thereby improving the accuracy and reliability of the detection. This layout also reduces the misjudgment caused by magnetic field interference, thereby improving the overall performance of the equipment.

[0033] Further, the magnetic ring switch 314 is provided with a first magnet block 315 capable of generating a stable magnetic field. The stable magnetic field provided by the first magnet block provides a reliable detection reference for the Hall sensor body 327, thereby ensuring the accuracy of the magnetic field change. This design not only improves the detection precision, but also enhances the stability and anti-interference ability of the equipment.

[0034] Embodiment two: please refer to Figures 1-6And combined with embodiment one, further get, induction assembly 32 further includes the first annular plate 321 arranged outside the material receiving hopper 1, the top end of the first annular plate 321 is provided with a support column 322, the top end of the support column 322 is provided with a second annular plate 323, the support column 322 is provided with a connecting frame 324 outside, the connecting frame 324 is movably provided with an adjusting screw 325, the adjusting screw 325 is externally threadedly connected with a connecting plate 326, and the Hall sensor body 327 is arranged outside the connecting plate 326. Through the combination of the adjusting screw 325 and the connecting plate 326, the position of the Hall sensor body 327 is flexibly adjusted, so that the detection requirements of different materials and material falling speeds can be adapted. This design not only improves the flexibility and applicability of the equipment, but also reduces the adjustment cost of the equipment caused by material changes.

[0035] Further, the connecting plate 326 is provided with a second magnet block 328 close to one side of the first magnet block 315. The interaction between the second magnet block 328 and the first magnet block 315 enhances the change amplitude of the magnetic field, and improves the sensitivity of the Hall sensor body 327 to the change of the magnetic field.

[0036] Further, the connecting frame 324 is provided with a sliding groove for sliding the adjusting screw 325 to adjust the transverse position of the connecting plate 326. The design of the sliding groove enables the adjusting screw 325 to slide smoothly, so that the position of the Hall sensor body 327 can be quickly and accurately adjusted.

Then, rotate the connecting plate 326, so that it rotates outside the adjusting screw 325, thereby locking the position of the adjusting screw 325.

[0039] Subsequently, the vacuum suction machine body 2 starts to suck the material and release the material to the surface of the material cover plate 313. Under the action of the gravity of the material, the material cover plate 313 rotates in the connecting seat 312. This rotating action changes the magnetic field formed by the magnetic ring switch 314, the first magnetic block 315 and the second magnetic block 328. The Hall sensor body 327 can monitor the change of the magnetic field and transmit the corresponding signal to the external control device.

[0040] When the material falling process is completed, the position of the material cover plate 313 changes due to the loss of the gravity of the material, thereby changing the magnetic field formed between the first magnetic block 315 and the second magnetic block 328. This change of the magnetic field is also captured by the Hall sensor body 327 and a signal is generated, thereby completing the detection of the whole material falling process.
