[0018] See Figure 1-3 The diagram shows a rotating box-opening mechanism, including a vertically mounted wall panel 1. A first servo motor 2 is vertically mounted on the upper part of one side of the wall panel 1. The output end of the first servo motor 2 is connected to a first synchronous pulley 3. The first synchronous pulley 3 is connected to a pulley at the end of a cam disc shaft 5 via a first synchronous belt 4. After the cam disc shaft 5 passes through the wall panel 1, a cam disc 6 is fixedly mounted on its other end. An arc-shaped sliding groove 7 is provided on the cam disc 6 along the circumferential direction. A second servo motor 8 is mounted below the first servo motor 2. The output end of the second servo motor 8 is connected to a second synchronous pulley 9. The second synchronous pulley 9 is connected to a pulley at the end of a large turntable shaft 11 via a second synchronous belt 10. The large turntable shaft 11... It has a tubular structure. The large turntable shaft 11 is sleeved on the cam disk shaft 6. One end of the large turntable shaft 11 passes through the wall panel 1 and the rear end is installed with the large turntable 12. The large turntable 12 is sleeved on the outer ring of the cam disk 6. A fixing groove 13 is opened on the large turntable 12 along the circumferential direction. An installation block 14 is set in the fixing groove 13. A guide rail 15 is slidably set on the upper end of the installation block 14. A guide rail seat 16 is set on the end of the guide rail 15 near the center of the cam disk 6. A connecting rod is set on the lower end of the guide rail seat 16. A needle roller bearing 17 is sleeved on the end of the connecting rod and then embedded in the arc-shaped sliding groove 7. A suction cup seat 18 is installed on the end of the guide rail 15 away from the center of the cam disk 6. An elliptical suction cup 19 is set on one side of the suction cup seat 18.
[0019] The large turntable shaft 11 is fitted with a bearing seat 20 on its outer side. An air passage plate 21 is fixed to the end of the bearing seat 20. Several air source interfaces are formed along the circumferential direction on the air passage plate 21, and these interfaces are connected to the suction cup seat 18 via air pipes. A compression spring 22 is also provided on one side of the air passage plate 21, and the compression spring 22 is fitted onto the outer wall of the bearing seat 20.

[0020] The rotary box-opening mechanism of this application consists of four sets of elliptical suction cups 19 forming a material handling unit. The elliptical suction cups 19 are assembled at 90° intervals on the cam disk 6 through suction cup bases 18, guide rails 15, and other components. Relying on the rotation of the cam disk 6 and the guidance of the guide rails 15, the reciprocating material handling action is completed. The first servo motor 2 serves as the power source, transmitting power through the first synchronous belt 4 and the first synchronous pulley 3 to drive the cam disk 6 to rotate. In conjunction with components such as the needle roller bearing 17, stable motion transmission is ensured, achieving a precise 90-degree rotation cycle of the cam disk 6.

[0021] The working principle of this rotating box-opening mechanism is as follows:
[0022] The first servo motor 6 starts, driving the cam disk 6 to rotate via the transmission system. Every 90° rotation, the cam disk 6 drives the elliptical suction cup 19 to reciprocate along the guide rail 15. It precisely retrieves the inner-clamp paper card from the cardboard box hopper and transfers it to the forming station for unloading, completing one round of material handling. This continuous cycle, in conjunction with the forming mechanism, achieves efficient box opening, and the material handling and box opening speed is compatible with the preceding equipment, ensuring seamless production continuity.
[0023] This application has the following advantages over traditional box-opening mechanisms:
[0024] The rotary box opening method adopted in this application significantly shortens the box opening operation time and greatly improves production efficiency through simpler control methods. Through the optimized design of the rotary mechanism, mechanical wear is effectively reduced, the service life of the equipment is extended, and maintenance costs are significantly reduced. It not only enhances the stability and reliability of the equipment, but also provides a solid guarantee for the optimization of subsequent production processes and effectively solves the problems encountered when docking with upstream equipment.
