Description

Technical Field

[0001] The utility model relates to the technical field of magnetic core production, in particular to a centrifugal feeding device for a magnetic core detection device. Background Technique

[0002] Magnetic cores are produced through a sintering process. Inductors are made by winding electrical conductors around the magnetic cores and are the main materials of transformers. During the production of magnetic cores, the divided magnetic cores usually need to be detected. They are conveyed by a conveyor belt and pass through a detection mechanism to detect the magnetic flux of the magnetic cores and screen out the complete magnetic cores that meet the production requirements in terms of quality.

[0003] Before the magnetic cores enter the detection mechanism, they are stacked and scattered on the conveyor belt, which cannot guarantee the subsequent detection effect. Some manufacturers set up workstations on one side of the conveyor belt and manually arrange the magnetic cores in a single row, which not only has low efficiency but also increases the labor cost. Content of the Utility Model

[0004] In order to improve the problems of the magnetic cores before detection in the above background technique, the utility model provides a centrifugal feeding device for a magnetic core detection device.

[0005] The centrifugal feeding device for a magnetic core detection device provided by the utility model adopts the following technical scheme:

[0006] A centrifugal feeding device for a magnetic core detection device includes a rotating bin. A hopper is arranged above the rotating bin, and the discharging end of the rotating bin is connected to a conveyor belt. The rotating bin includes a centrifugal turntable. A feeding track is fixedly arranged around the edge of the centrifugal turntable, and a baffle is arranged outside the feeding track.

[0007] Preferably, the centrifugal turntable is driven by a rotating motor arranged inside the rotating bin. An air duct is arranged inside the centrifugal turntable, and uniformly arranged air holes are opened on the surface of the centrifugal turntable. The air duct is connected to an air pump.

[0008] Preferably, a stop bar is installed at the discharging end of the rotating bin, and a single magnetic core can pass through between the stop bar and the baffle.

[0009] Preferably, the conveyor belt is arranged obliquely downward. After the magnetic cores fall onto the conveyor belt, they are fed along the conveyor belt under the action of their own weight.

[0010] Preferably, a vertical support column is installed on one side of the rotating bin. A chute is opened in the vertical direction of the support column and is slidably connected to a support arm. The end of the support arm is connected to a limiting plate, and the lower end of the limiting plate is close to the surface of the centrifugal turntable.

[0011] Preferably, the outer edge of the baffle is inclined inward to prevent the magnetic cores from falling on the feeding track under the action of centrifugal force.

[0012] Preferably, the rotary bin is installed on the workbench, and a damping block is arranged at the connection position between the workbench and the rotary bin.

[0013] In summary, the utility model has the following beneficial technical effects:

[0014] 1. The magnetic cores enter the rotary bin along the hopper, rotate with the centrifugal turntable and fall into the edge conveying track under the centrifugal force, and are blocked by the baffle and the retaining strip to form a queue, so that the single magnetic core passes through the discharge end of the rotary bin and is conveyed along the conveyor belt, which is convenient for subsequent detection of the magnetic cores, improves the efficiency, and at the same time eliminates the need for manual operation, reducing the labor cost.

[0015] 2. An air duct is arranged in the centrifugal turntable, and the air duct is connected to an air pump. The gas is ejected from the air holes on the surface of the centrifugal turntable to form an air film on the surface of the centrifugal turntable, reducing the friction with the magnetic cores and preventing the magnetic cores from accumulating and falling on the surface of the centrifugal turntable.
