The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0017] Embodiments of the present utility model: Figure 1-Figure 4 As shown, an auxiliary tooling for rotating the conjugate cam of a packaging machine includes a support plate 1, which is a rectangular plate. A circular hole 2 is opened at one end of the support plate 1, and a plurality of mounting holes 3 are opened around the circular hole 2. A shell 4 is installed on the support plate 1, and a rotating shaft 5 and a reduction gear set are arranged in the shell 4. The rotating shaft 5 is connected to the reduction gear set, and a retractable connecting block 6 is installed in the rotating shaft 5. A driving handle 7 is installed on the reduction gear set.

[0018] The connecting block 6 is used to connect with the notch on the conjugate cam shaft coupling, so as to drive the conjugate cam shaft to rotate through the shaft 5, and the setting of the reduction gear group can realize the manual easy driving of the conjugate cam shaft to rotate, thereby solving the problem in the prior art that it is difficult to manually rotate the conjugate cam shaft.

[0019] In a specific embodiment, the housing 4 includes a gear set housing 8 and a shaft housing 9, and the shaft housing 9 is connected to the inside of the gear set housing 8, and the two are integrally formed. The gear set housing 8 is used to install the reduction gear set. In this embodiment, a gourd-shaped gear installation bin 21 is formed in the gear set housing 8, and the gourd-shaped gear installation bin 21 is covered by a bin cover 22, and the bin cover 22 is also gourd-shaped. The shaft housing 9 is used to install the shaft 5.

[0020] Furthermore, the reduction gear set includes a driving gear 10 and a driven gear 11, the diameter of the driving gear 10 is smaller than the diameter of the driven gear 11, one end of the rotating shaft 5 is fixedly connected to the driven gear 11, and the rotating shaft 5 is coaxial with the driven gear 11, the driving gear 10 is rotatably installed in the smaller bin body in the gourd-shaped gear mounting bin 21 through the rotating shaft, and the driven gear 11 is installed in the larger bin body in the gourd-shaped gear mounting bin 21, and the driving gear 10 is meshed with the driven gear 11.

[0021] The driving gear 10 uses a gear with a smaller diameter, which can reduce speed and save effort. By driving the driving handle 7 to rotate the driving gear 10, the driven gear 11 can be easily driven to rotate, thereby rotating the conjugate cam shaft through the shaft 5 and the connecting block 6.

[0022] Furthermore, a bearing 12 is provided in the shaft housing 9, and the outer ring surface of the bearing 12 is interference fit with the inner wall of the shaft housing 9, and the outer wall of the shaft 5 is interference fit with the inner ring surface of the bearing 12. The arrangement of the bearing 12 can make the shaft 5 and the driven gear 11 rotate easily, reducing friction.

[0023] Furthermore, a rectangular hole 13 is opened in the rotating shaft 5, and a circular hole 14 is opened at the center position of the driven gear 11. The rectangular hole 13 is connected to the circular hole 14, and the connecting block 6 is plugged into and slidably matched with the rectangular hole 13. An end plate 15 is fixedly provided at one end of the connecting block 6 located in the circular hole 14, and a spring 16 and an end cover 17 are also provided in the circular hole 14.

[0024] The end cover 17 is threadedly connected to the circular hole 14 , and the spring 16 is used to provide elastic force so that the end of the connecting block 6 extends out of the rotating shaft 5 . At the same time, the spring 16 is provided so that the connecting block 6 has a telescopic function.

[0025] Furthermore, a hexagonal groove 18 is axially provided on the rotating shaft of the driving gear 10 , the driving handle 7 is in a "Z" shape, and a hexagonal rod 19 is provided at the end of the driving handle 7 , and the hexagonal rod 19 is plugged into and matched with the hexagonal groove 18 .

[0026] The working principle of the utility model is as follows: when in use, one end of the support plate 1 is fixed on the vise, and then the rear seat of the No. 1 wheel is placed on one side of the support plate 1, and the housing 4 is placed on the other side of the support plate 1, and four bolts 20 are used to pass through the four second mounting holes 23 on the housing 4 and the four mounting holes 3 on the support plate 1 and then connected with the four threaded holes on the rear seat of the No. 1 building. Use the driving handle 7 to adjust the angle of the connecting block 6 so that it is roughly aligned with the notch on the conjugate cam shaft coupling, and then tighten the four bolts 20. At this time, there are two situations, one is that the connecting block 6 is directly inserted into the notch on the conjugate cam shaft coupling to achieve effective connection, and the other is that the connecting block 6 is not aligned with the notch. In this case, due to the setting of the spring 16, the connecting block 6 compresses the spring and moves in the direction close to the end cover 17. When the driving handle 7 is turned, the shaft 5 rotates slowly. When the connecting block 6 is aligned with the notch, the connecting block 6 will automatically be inserted into the notch under the action of the spring 16 to achieve effective connection with the notch.

[0027] Insert the hexagonal rod 19 on the driving handle 7 into the hexagonal groove 18, and rotate the driving gear 10 through the driving handle 7, which drives the driven gear 11 to rotate, and the driven gear 11 rotates the shaft 5, and the shaft 5 rotates with the conjugate cam shaft and the coupling thereon through the connecting block 6. The conjugate cam shaft cooperates with the 8 cam shafts in the first wheel to drive the four cigarette clamps to open and close. At this time, the staff can use the cigarette clamp adjustment tool of the packaging machine to adjust the cigarette clamp. This greatly improves the adjustment efficiency.

[0028] The above describes in detail the structure, features and effects of the utility model based on the embodiments shown in the drawings. The above is only a preferred embodiment of the utility model, but the utility model is not limited to the scope of implementation shown in the drawings. Any changes made in accordance with the concept of the utility model, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and the drawings, should be within the protection scope of the utility model.
