[0032] like Figures 2 to 4 As shown, for the weak magnetic sheet discharging mechanism, the present invention provides a specific embodiment, in which the weak magnetic sheet discharging mechanism 30 includes a discharging turntable 301, a rotating motor 302, a pushing cylinder 303 and a discharging assembly 304; the discharging turntable 301 is fixed on the motor shaft of the rotating motor 302 and rotates by the rotating motor 302; the discharging turntable 301 is evenly distributed with a plurality of loading sleeves 305 along the circumferential direction, and each loading sleeve 305 is respectively provided with a discharging pipe 306 for holding weak magnetic sheets; the pushing cylinder 303 is arranged above the discharging turntable 301, and the pushing cylinder 303 is used to push out the weak magnetic sheets in the loading sleeve 305; the discharging assembly 304 is located on one side of the discharging turntable 301, and the discharging assembly 304 includes a discharging guide rail 3041 for receiving weak magnetic sheets.
[0033] In the above embodiment, a material tube limiting ring 3011 is fixedly provided above the discharge turntable 301, and the material tube limiting ring 3011 is provided with limiting spring pieces 3012 of the same number as the discharge tubes 306, and the discharge tubes 306 are stuck in the limiting spring pieces 3012; a plurality of support columns are provided between the material tube limiting ring 3011 and the discharge turntable 301.
[0034] In this embodiment, the discharging assembly 304 includes a discharging motor 3042, a synchronous belt 3043, a synchronous wheel 3044 and a weak magnetic sheet material transfer belt 3045; the discharging motor 3042 is fixed under the discharging guide rail 3041, and a driving wheel 3046 is installed on the output shaft of the discharging motor 3042.

[0035] In addition, a positioning column 3051 is provided inside the feeding sleeve 305, and a limit block 3052 connected thereto is provided below the positioning column 3051. The limit block 3052 drives the positioning column 3051 to move up and down inside the feeding sleeve 305. A telescopic spring is sleeved on the positioning column 3051, and the telescopic spring is used to keep the positioning column 3051 in an extended state.

[0036] Combined with the above structure, the working process of the present invention is described in detail.

The limiting spring sheet 3012 keeps the discharge pipe 306 in a detachable state. When the weak magnetic sheets in the discharge pipe 306 are loaded, the discharge pipe 306 can be replaced. During discharge, the weak magnetic sheet at the bottom of the discharge pipe 306 is located above the positioning column 3051 under the action of gravity, and the positioning is achieved by the positioning column 3051. When discharge is required, the positioning cylinder 3071 drives the lifting seat 3072 to move downward, pulls the limiting block 3052, and drives the positioning column 3051 to retract. Since the card slot of the lifting seat 3072 is in a through state, when the discharge turntable 301 rotates, the limiting block 3052 passes through the card slot, which can achieve the pulling of multiple limiting blocks 3052.

In the present embodiment, four loading sleeves 305 are evenly distributed on the discharge turntable 301; a sliding push slider 3014 and a push rod 3015 are provided in the push chute 3013, one end of the push rod 3015 is connected to the push slider 3014, and a push nut is fixedly installed on the push slider 3014; the top end of the cylinder rod of the push cylinder 303 is connected to a push clamp 3031, and the push clamp 3031 has an opening, and when the push chute 3013 is docked with the discharge assembly, the push nut is located in the opening of the push clamp 3031. When the cylinder of the push cylinder 303 extends, the push clamp and the push nut cooperate to drive the push slider 3014 and the ejector rod 3015 to move together, and the ejector rod 3015 pushes the weak magnetic sheet to the weak magnetic sheet conveying belt 3045, so as to realize the loading of the weak magnetic sheets one by one. The present invention can realize the automatic discharge of the weak magnetic sheets, improve the discharge efficiency, reduce the labor intensity, and has high discharge efficiency; the discharge pipe 306 can be replaced after the loading is completed, and the mechanism can run uninterruptedly, which greatly improves the discharge efficiency.
