As shown in Figure 6 , the clamping piece 8 comprises a clamping frame 81, a first arc-shaped clamping plate 82 and a second arc-shaped clamping plate 83, and a driving piece.

[0057] As shown in Figure 6 , the clamping frame 81 is in an inverted U-shaped structure, comprising a horizontal plate 811, one vertical plate 812 is fixedly arranged at each end of the horizontal plate 811, and the horizontal plate 811 is fixedly connected with the second connecting plate 72.

[0058] The driving piece is used to drive the first arc-shaped clamping plate 82 and the second arc-shaped clamping plate 83 to move towards or away from each other. The driving piece is arranged on the clamping frame 81, and the output end of the driving piece is connected with the first arc-shaped clamping plate 82 and the second arc-shaped clamping plate 83. Specifically, the driving piece comprises a motor 9 and a bidirectional screw 10, the motor 9 is installed in a mounting frame 13 through a motor base, the mounting frame 13 is fixedly connected with the vertical plate 812 on the clamping frame 81, the axial direction of the bidirectional screw 10 extends along the X direction or the Y direction, in other words, the axial direction of the bidirectional screw 10 extends along the horizontal direction, and in the embodiment, the axial direction of the bidirectional screw 10 extends along the Y direction. The bidirectional screw 10 is connected with the output shaft of the motor 9, the bidirectional screw 10 penetrates through the two vertical plates 812 and is rotatably connected with the vertical plates 812 through bearings, and the bearings are arranged on the vertical plates 812. Figure 2 、 6Not shown. In order to enable the first curved splint 82 and the second curved splint 83 to slide axially along the bidirectional lead screw 10, a first movable rod 11 and a second movable rod 12 are threadedly sleeved on the bidirectional lead screw 10. The first movable rod 11 and the second movable rod 12 are located at positions on the bidirectional lead screw 10 that rotate in opposite directions. The first curved splint 82 is fixed to the bottom end of the first movable rod 11, and the second curved splint 83 is fixed to the bottom end of the second movable rod 12.

The top ends of the first movable rod 11 and the second movable rod 12 are inserted into the limiting groove. During operation, the motor 9 drives the bidirectional lead screw 10 to rotate. Since the first movable rod 11 and the second movable rod 12 are located at positions that rotate in opposite directions, the first movable rod 11 and the second movable rod 12 will move relative to or away from each other on the bidirectional lead screw 10, thereby causing the first curved splint 82 and the second curved splint 83 to move relative to or away from each other.

[0059] It should be noted that, in this embodiment, the driving member selects the motor 9 and the bidirectional screw 10 for use in combination.

Here, adaptation means that the curvature of the clamping surface of the first curved clamping plate 82 and the curvature of the clamping surface of the second curved clamping plate 83 are both equal to the curvature of the outer surface of the milk powder can. This structure can ensure that the first curved clamping plate 82 and the second curved clamping plate 83 are tightly fitted to the milk powder can and clamp the milk powder can. During operation, the motor 9 rotates, driving the bidirectional screw 10 to rotate, and the first curved clamping plate 82 and the second curved clamping plate 83 move relative to each other, thereby clamping the milk powder can. The motor 9 reverses, and the first curved clamping plate 82 and the second curved clamping plate 83 move away from each other, releasing the milk powder can.

[0061] When the embodiment is used, the X-direction moving assembly 5, the Y-direction moving assembly 4 and the Z-direction moving assembly 6 are adjusted to move the clamping mechanism to the milk powder can area and align the milk powder can, the motor 9 is started, the first arc-shaped clamping plate 82 and the second arc-shaped clamping plate 83 move oppositely to clamp the milk powder can, the moving mechanism is used to move the clamping mechanism clamping the milk powder can to the position of the packaging box, the motor 9 is reversed, the first arc-shaped clamping plate 82 and the second arc-shaped clamping plate 83 move oppositely to release the milk powder can, and the milk powder can falls into the packaging box.
