Description

Technical Field

[0001] The present application relates to the technical field of electromagnetic vibrating feeders, and more specifically, to a resonance adjustment structure of an electromagnetic vibrating feeder. Background Art

[0002] Electromagnetic vibrating feeder is a kind of machine which realizes continuous and uniform conveying of materials through high-frequency vibration of electromagnetic vibrator. In order to ensure the stable and efficient operation of electromagnetic vibrating feeder, it is necessary to control the resonance adjustment structure on the electromagnetic vibrating feeder to avoid the increase of current and decrease of amplitude during the actual operation of the electromagnetic vibrating feeder, which will lead to a significant decrease in working efficiency, increase in energy consumption and unstable material transportation.

[0003] After searching the announcement number: CN218167321U, a resonance adjustment structure of an electromagnetic vibrating feeder is disclosed, which includes a driver and a feeding trough. An electromagnet is fixedly provided at the bottom of the driver housing, and a connecting fork is fixedly provided at the bottom of the feeding trough. The connecting fork is connected to the driver housing through a leaf spring group; an armature is fixedly provided at the bottom of the connecting fork, which can adjust the resonance index of the electromagnetic vibrating feeder by adjusting the distance of the magnetic spring pairs or adjusting the magnetic field strength between the magnetic spring pairs.

[0004] In actual use, the resonance index is adjusted by controlling the rotation of the magnet fixing seat to adjust the distance between permanent magnet B and permanent magnet A. When the electromagnet stops supplying power, the leaf spring group provides support for the feed trough. If there is too much material in the feed trough, the overall weight of the feed trough is too large, which may easily cause the leaf spring group to bear too much pressure due to the weight of the feed trough after the electromagnet stops supplying power, resulting in metal fatigue or even breakage.

[0005] In order to solve the above problems, the present application provides a resonance adjustment structure of an electromagnetic vibrating feeder. Utility Model Content

[0013] Furthermore, a spring is fixedly installed at the bottom end of the lifting block, and the bottom end of the spring is fixedly connected to the bottom inner wall of the lifting slot.

[0014] The above technical solution can facilitate the guarantee that the lifting block can provide buffering through the spring during the descending process.

[0015] Furthermore, four plug holes are provided on the bottom plate of the feed trough, and the diameter of the plug holes is the same as the diameter of the lifting rod.

[0016] The above technical solution can facilitate the guarantee that the feed trough can move vertically and downward synchronously with the lifting rod.

[0017] Furthermore, the connection plate is connected to the lifting plate and the armature through a threaded rod, and the lifting plate and the armature are provided with threaded grooves matching the threaded rod.

[0018] The above technical solution makes it easy to dismantle the armature for maintenance at a later stage.

[0019] In summary, this application includes the following beneficial technical effects:

When the feed trough is not in use, the feed trough falls downward and is supported by the leaf spring assembly for buffering, and can directly contact the fixed plate to avoid excessive load on the leaf spring assembly.
