Description

The outer end of the abutting convex rod 35 abuts against the peripheral surface of the positioning disk 2. The rotating disk 1 rotates and drives a plurality of opening and closing clamping units 3 to rotate synchronously. When the outer end of the abutting convex rod 35 abuts against the convex arc surface section 21 of the positioning disk 2, the abutting convex rod 35 is pressed by the convex arc surface section 21 and rotates outward. The abutting convex rod 35 rotates and drives the driving rotating rod 31 and the driven rotating rod 32 to rotate relatively, and causes the driving clamping rod 33 and the driven clamping rod 34 to open. When the outer end of the abutting convex rod 35 abuts against the concave arc surface section 22 of the positioning disk 2, the abutting convex rod 35 rotates inward. The abutting convex rod 35 rotates and drives the driving rotating rod 31 and the driven rotating rod 32 to rotate relatively, and causes the driving clamping rod 33 and the driven clamping rod 34 to clamp.

[0022] As Figures 1 to 4 shown, in order to facilitate the relatively stable rotation of the driving rotating rod 31 and the driven rotating rod 32, further, a driving engaging block 311 is provided on the driving rotating rod 31. A driven engaging block 321 is provided on the driven rotating rod 32. The inner sides of the driving engaging block 311 and the driven engaging block 321 are rotationally connected by meshing with teeth.

[0023] As Figures 1 to 4 shown, in order for the driving rotating rod 31 and the driven rotating rod 32 to obtain an elastic restoring force for relatively stable rotation, further, a first torsion spring 4 and a second torsion spring 5 are respectively sleeved on the driving rotating rod 31 and the driven rotating rod 32. The inner ends of the first torsion spring 4 and the second torsion spring 5 are respectively fixed to the driving rotating rod 31 and the driven rotating rod 32. The outer ends of the first torsion spring 4 and the second torsion spring 5 are elastically connected by an elastic connecting rib 6.

[0024] As Figures 1 to 4As shown, in order to form a stable rotation and avoid collisions, further, a through slot 331 is provided on the active clamping rod 33; the driven clamping rod 34 is inserted through the through slot 331 of the active clamping rod 33 to form an X-shaped structure.

[0025] As Figures 1 to 4 As shown, in order to facilitate stable rod clamping, further, the inner side surface of the active clamping rod 33 is of an arc structure; an arc-shaped abutting block 341 is provided at the end of the driven clamping rod 34, and a rod clamping opening 342 is provided on the inner side of the arc-shaped abutting block 341; when the active clamping rod 33 and the driven clamping rod 34 are clamped, the arc-shaped abutting block 341 abuts against the inner side surface of the active clamping rod 33. Further, a rolling wheel 351 is provided at the outer end of the abutting convex rod 35; the rolling wheel 351 is in rolling connection with the peripheral surface of the positioning disk 2. Further, the peripheral surface of the positioning disk 2 is made of a wear-resistant material. Further, the outer convex arc surface section 21 and the inner concave arc surface section 22 on the positioning disk 2 are connected by a smooth arc surface in a transitional manner.

[0026] The present invention can form stable clamping and opening operations. The rotating disk 1 of the present invention rotates and drives a plurality of opening and closing clamping units 3 to rotate synchronously. The abutting convex rod 35 will sequentially abut against the outer convex arc surface section 21 and the inner concave arc surface section 22 on the peripheral surface of the positioning disk 2. When the abutting convex rod 35 abuts against the outer convex arc surface section 21 of the positioning disk 2, the abutting convex rod 35 is pressed by the outer convex arc surface section 21 and rotates outward. The abutting convex rod 35 rotates and drives the active rotating rod 31 and the driven rotating rod 32 to rotate relative to each other, and causes the active clamping rod 33 and the driven clamping rod 34 to move in an opening manner; when the abutting convex rod 35 abuts against the inner concave arc surface section 22 of the positioning disk 2, the abutting convex rod 35 rotates inward. The abutting convex rod 35 rotates and drives the active rotating rod 31 and the driven rotating rod 32 to rotate relative to each other, and causes the active clamping rod 33 and the driven clamping rod 34 to move in a clamping manner, so that stable operations can be achieved.

[0027] In the present invention, an active engagement block 311 is provided on the active rotating rod 31, and a driven engagement block 321 is provided on the driven rotating rod 32. The inner sides of the active engagement block 311 and the driven engagement block 321 are rotationally connected through meshing of teeth. In this way, the active rotating rod 31 and the driven rotating rod 32 can be relatively engaged and connected to achieve relative rotation. When the outer end of the abutting convex rod 35 abuts against the outer convex arc surface section 21 of the positioning disk 2, the abutting convex rod 35 is pressed by the outer convex arc surface section 21 and rotates outward. The abutting convex rod 35 drives the active rotating rod 31 to rotate. When the active rotating rod 31 rotates, it drives the driven rotating rod 32 to rotate relatively through meshing transmission. In this way, the active clamping rod 33 and the driven clamping rod 34 perform an opening movement; when the abutting convex rod 35 abuts against the inner concave arc surface section 22 of the positioning disk 2, the abutting convex rod 35 no longer receives the pressing of the outer convex arc surface section 21. The active rotating rod 31 and the driven rotating rod 32 can obtain a stable elastic restoring force for mutual rotational reset through the first torsion spring 4, the second torsion spring 5, and the elastic connecting rib 6, enabling the active clamping rod 33 and the driven clamping rod 34 to perform a more stable clamping movement. In this way, it is convenient to drive the opening and closing movements of the active clamping rod 33 and the driven clamping rod 34, achieving stable clamping and opening.

[0028] In the present invention, a section of outer convex arc surface section 21 and a section of inner concave arc surface section 22 are provided on the peripheral surface of the designed positioning disk 2. In this way, the active clamping rod 33 and the driven clamping rod 34 are kept open for a period of time and kept clamped for a period of time. In this way, stable and sufficient discharging can be achieved during opening, and stable clamping of the package can be achieved during clamping, and the structure is reliable.

[0029] A through slot 331 is provided on the active clamping rod 33 of the present invention. The driven clamping rod 34 is inserted through the through slot 331 of the active clamping rod 33 to form an X-shaped structure. Through the X-shaped cross-clamping structure and the relative rotation of the driven rotating rod 32 and the active rotating rod 31, when the driven clamping rod 34 and the active clamping rod 33 open, they are not easily collided with the driven clamping rods 34 and the active clamping rods 33 of other opening and closing clamping units 3. The structure is stable, and the driving process is simple and reliable.
