Likewise, the length of the outer slope 8b is greater than the length of the inner slope 7b in the vertical direction.

The fixed grabbing component comprises a vertical shaft 9 welded at the bottom of the suspender 6; three auxiliary rods 10 are welded in the middle of the vertical shaft 9, a fixed disc 11 is welded at the bottom of the vertical shaft 9, and three dovetail grooves 11a are formed in the fixed disc 11.

The movable grabbing component comprises a movable disc 12 vertically matched with the upper part of the vertical shaft 9 in a sliding manner, and an extension rod 12a supported at the upper end of the outer support frame 8 is welded on the arc surface of the movable disc 12.

The bottom of the movable disc 12 is provided with three sub-grooves 12b, each sub-groove 12b is slidably provided with an upper driving rod 13, and the upper part of each upper driving rod 13 is provided with an inclined groove 13a which is in sliding fit with the corresponding auxiliary rod 10.

The movable grabbing assembly further comprises three lower driving rods 14 in sliding fit with the corresponding dovetail grooves 11a, and a clamping groove 14a for vertically and slidably mounting the lower portion of the corresponding upper driving rod 13 is formed in the upper portion of each lower driving rod 14. The bottom of each lower driving rod 14 is provided with a bayonet 14 b.

Each inclined groove 13a forms an angle of 45 degrees with the horizontal plane.

In the present invention, the cross section of the upper part of the central shaft 2 is square. The pitch angle between each adjacent two lower drive rods 14 may be set to 120 degrees. The inner straight slope 7a and the outer straight slope 8a correspond in position. The three sub-grooves 12b correspond to the three positions having the dovetail grooves 11 a. The inner supporting frame 7 and the outer supporting frame 8 are concentric and the position of the center of the circle corresponds to the position of the central shaft 2.

Before specific use, the stamping device is arranged on the ground base plate 1 and located at the left side between the inner support frame 7 and the outer support frame 8, and the storage box shown in fig. 8 and 9 is arranged on the ground base plate 1 and located at the right side between the inner support frame 7 and the outer support frame 8.

Wherein, the storage box is formed by integrating a box body 15 and an L-shaped upper cover 16; the bottom of the box body 15 is provided with a spring 17, and the spring 17 is connected with a bearing plate 18 which is vertically and slidably arranged in the box body 15. The circular plates as shown in fig. 7 are vertically stacked on the supporting plate 18, and the uppermost circular plate is pressed against the upper cover 16 by the elastic force of the spring 17. In addition, in order to reduce friction, rollers are provided at the portion where the boom 6 is supported at the upper end of the inner support frame 7 and the portion where the extension bar 12a is supported at the upper end of the outer support frame 8.

When the gear tooth type rotary kiln is used specifically, the motor 3 drives the incomplete gear 5 to rotate, and under the transmission action of the gear teeth, the central shaft 2 and the axis of the central shaft 2 around which the suspender 6 can rotate clockwise. During the rotation, when the boom 6 rotates to just cross the inner straight slope 7a, the incomplete gear 5 is disengaged from the output gear 4 and the extension rod 12a rotates just to cross the outer straight slope 8a, i.e. under the action of gravity, the boom 6, the fixed grabbing component and the movable grabbing component all move downwards, and the auxiliary rod 10 and the upper driving rod 13 descend together. When the hanging rod 6 and the fixed grabbing component fall to the lower part of the inner straight slope 7a and cause the auxiliary rod 10 to fall and stop, at this time, the three bayonets 14b fall to the same height as the topmost round plate, but because the movable grabbing component does not fall to the bottom of the outer straight slope 8a yet, the upper driving rod 13 continues to fall, i.e. the auxiliary rod 10 slides upwards relatively in the corresponding inclined groove 13a, and all the upper driving rod 13 and the lower driving rod 14 respectively slide to the radial inner side of the fixed disc 11 along the track of the sub-groove 12b and the track of the dovetail groove 11a through the extrusion of the auxiliary rod 10 to the inner side wall of the inclined groove 13a in the sliding process, i.e. the movement of the three clamping grooves 14b can carry out spacing type clamping on the topmost round plate, so when the incomplete gear 5 and the output gear 4 resume rotating and meshing transmission, the circular plate can rotate together with the hanger rod 6, and the circular plate can be conveyed in a rotating mode.

When the hanger rod 6 rotates and climbs over the inner slope 7b, the extension rod 12a climbs over the outer slope 8b, so that the hanger rod 6, the fixed grabbing component and the movable grabbing component all move upwards, the auxiliary rod 10 and the upper driving rod 13 ascend together, and in the whole ascending process, the ascending speed of the auxiliary rod 10 is slower than that of the upper driving rod 13, so that the auxiliary rod 10 slides downwards in the corresponding inclined groove 13a relatively, all the upper driving rod 13 and the lower driving rod 14 slide outwards in the radial direction of the fixed disc 11 correspondingly along the track of the sub-groove 12b and the track of the dovetail groove 11a, and the three bayonets 14b move outwards in the radial direction to release the limiting clamping of the transported circular plate, namely, the circular plate is released to a stamping device, and one-time automatic feeding is realized.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
