[0028] The working principle of the magnetic core detection device with screening function disclosed in the present invention is as follows: when in use, the magnetic cores 4 are first placed on the conveyor belt 201 in sequence, and then the drive motor 204 is started. The output shaft of the drive motor 204 drives the hexagonal prism 217 to rotate, and the rotation of the hexagonal prism 217 drives the arc-shaped rack bracket 222 to rotate. It should be noted that the arc-shaped rack bracket 222 and the hexagonal prism 217 are spline-matched, and the rotation of the arc-shaped rack bracket 222 drives the protrusion 2221 to rotate together. At this time, the arc-shaped rack bracket 222 is located in the C-shaped frame 219, and the protrusion 2221 is in meshing state with the pit 2201, so the arc-shaped rack bracket 222 rotates and drives the intermittent gear 220 to rotate, the intermittent gear 220 rotates and drives the driving gear 203 to rotate, the driving gear 203 rotates and drives the conveyor pulley 202 to rotate, the conveyor pulley 202 rotates and drives the conveyor belt 201 to rotate, the conveyor belt 201 rotates and drives the magnetic core 4 to move, when the magnetic core 4 moves to the bottom of the electrode plate bracket 102, the arc-shaped rack bracket 222 rotates to the position as shown in FIG. Figure 7At the slope where the C-shaped frame 219 is set, the arc-shaped rack bracket 222 will rotate along the slope, and at this time the protrusion 2221 will separate from the pit 2201, so that the magnetic core 4 on the conveyor belt 201 will no longer move, and the arc-shaped rack 216 will mesh with the energy-applying gear 214, thereby driving the energy-applying gear 214 to rotate, and the rotation of the energy-applying gear 214 will drive the first pulley 211 to rotate through the first gearbox 212 and the first transmission belt 207, and the rotation of the first pulley 211 will drive the driving gear 209 to rotate, and the rotation of the driving gear 209 will drive the downward pressure rack 205 to move downward, and the downward pressure rack 205 The downward movement will drive the electrode plate bracket 102 to move downward, and the downward movement of the electrode plate bracket 102 will drive the electrode plate 109 to move downward. When the electrode plate 109 contacts the magnetic core 4, a loop will be formed between the electrode plate 109, the magnetic core 4 and the conveyor belt 201, thereby generating a corresponding current. The size of the resistance can be determined by the size of the current value. If the magnetic core 4 has a crack, the resistance value of the magnetic core 4 is relatively large. When the next magnetic core 4 moves to the bottom of the electrode plate bracket 102, the cylinder 105 is started to withdraw the magnetic core 4 from the conveyor belt 201, thereby screening out unqualified magnetic cores 4. When the arc-shaped rack 216 rotates to separate from the energy-applying gear 214, the downward pressure rack 205 will move upward under the action of the compression spring 104, and at the same time drive the driving gear 209 to rotate. The rotation of the driving gear 209 will drive the second pulley 210 to rotate, and the second pulley 210 drives the input shaft of the second gearbox 213 to rotate through the second transmission belt 208. At this time, the energy recovery gear 215 on the output shaft of the second gearbox 213 will rotate. At the same time, the arc-shaped rack 216 will rotate to the energy recovery gear 215 and mesh with the energy recovery gear 215. The rotating energy recovery gear 215 will drive the arc-shaped rack 216 to rotate. When the energy recovery gear 215 is separated from the arc-shaped rack 216, the arc-shaped rack bracket 222 rotates to a position where it falls into the gap of the C-shaped frame 219, and the pit 2201 and the protrusion 2221 are meshed again. It should be noted that if the angle between the energy applying gear 214 and the energy recovery gear 215 is 120°, the drive motor 204 can be in an idle state for one-third of the time, and the rotating energy recovery gear 215 can provide partial power for the drive motor 204 at this time.
