[0044] The conveying mechanism 7 includes an inclined rod 71, which can transmit the tooth plate 72. The top of the inclined rod 71 is connected to the bottom of the trapezoidal filter plate 61 through a hinge. The bottom of the inclined rod 71 is connected to the tooth plate 72 through a hinge. The outside of the tooth plate 72 is connected to the inside of the material box 1. The material box 1 can guide the tooth plate 72, thereby making the tooth plate 72 move linearly.

[0045] The back of the toothed plate 72 is meshingly connected with a gear 73, which can transmit the power to the pawl 74. The bottom of the gear 73 is connected with a spherical bearing 731 with a seat, which is connected to the material box 1 through a connecting arm, and the spherical bearing 731 with a seat can support the gear 73.

[0046] The interior of the gear 73 is connected to a pawl 74 via a spring hinge, and the exterior of the pawl 74 is meshedly connected to a ratchet 75.

One end of the pushing plate 81 close to the inner wall of the material box 1 is connected to a sliding rod 812, and the outer sliding connection of the sliding rod 812 is connected to a sleeve 811, which is connected to the material box 1. The sliding rod 812 cooperates with the sleeve 811 to guide the pushing plate 81, so that the pushing plate 81 can move in a straight line.

The highly conductive filler is guided by the guide plate 11, and the grinding unit 4 is started to grind the highly conductive filler. After being ground step by step by multiple groups of grinding units 4, the highly conductive filler falls on the top of the trapezoidal filter plate 61. The cam motor 5 is started to drive, and then the trapezoidal filter plate 61 is driven to move up and down. The moving trapezoidal filter plate 61 screens the highly conductive filler.

[0053] When the tooth plate 72 moves, it automatically drives the short-circuit arm 82 to transmit, and then drives the push plate 81 to move. The moving push plate 81 drives the high-conductive filler at the bottom of the material box 1, so that the high-conductive filler is discharged through the discharging mechanism 3. Through the added pushing mechanism 8, when the conveying mechanism 7 drives the high-conductive filler to move, the high-conductive filler is automatically scraped and discharged to avoid the high-conductive filler from being retained at the bottom of the material box 1, thereby preventing the high-conductive filler from being unable to be discharged normally.
