Abstract
Description
Technical Field
[0001] The utility model relates to packaging equipment, in particular to a medicine plate pushing mechanism of a blister packaging machine. Background Art
[0002] Blister packaging machine is a common packaging equipment. The medicine can be packaged in the formed blister medicine plate, and then the medicine plate is boxed to complete the entire packaging operation. After the medicine plate is loaded with medicine, it needs to be pushed into the boxing station for boxing through a pushing mechanism. The traditional pushing mechanism generally includes a transmission belt, a mounting seat is arranged on the transmission belt, and a push plate is set on the mounting seat. By controlling the movement of the transmission belt, the mounting seat and the pushing action can be driven to realize the pushing of the medicine plate. However, in actual use, the transmission belt will drive the mounting seat and the push plate to move in an arc when passing around the transmission wheel. This causes the pushing direction of the push plate and the contact surface with the medicine plate to change during this process, causing the medicine plate to be pushed and offset. The stability and accuracy of the pushing of the medicine plate are not good, affecting the subsequent boxing operation. Utility Model Content

[0006] A connecting shaft is extended from one end of the main swing arm, and the connecting shaft is rotatably set in a connecting seat. The connecting shaft is connected to the auxiliary swing arm, and a push plate is also installed on the auxiliary swing arm. A second guide member is installed at one end of the connecting shaft, and the second guide member is located in a second guide groove on the second frame plate. The trajectory of the second guide groove is set to be consistent with the moving trajectory of the transmission belt.

[0017] As shown in the figure, the medicine plate pushing mechanism of the blister packaging machine disclosed by the utility model includes a transmission belt 2, which is passed around the main transmission wheel 15. A connecting seat 9 is arranged and installed on the transmission belt 2. The connecting seat 9 is rotatably connected to one end of the main swing arm 6. The other end of the main swing arm 6 is provided with a first guide member 5, and the first guide member 5 is arranged in a first guide groove 4 on the first frame plate 3. A push plate 7 is installed on the main swing arm 6. The first guide groove 4 can guide the movement of the first guide member 5, drive the main swing arm 6 to swing, so that the push plate 7 always remains in a vertical state. Furthermore, a connecting shaft 8 is extended from one end of the main swing arm 6, and the connecting shaft 8 is rotatably set in the connecting seat 9. The connecting shaft 8 is connected to the auxiliary swing arm 10, and a push plate 7 is also installed on the auxiliary swing arm 10. A second guide member 12 is installed at one end of the connecting shaft 8. The second guide member 12 is located in the second guide groove 11 on the second frame plate 1. The trajectory setting of the second guide groove 11 is consistent with the moving trajectory of the transmission belt 2, which guides the connecting shaft 8 and further improves the stability of the entire mechanism. In this embodiment, the first guide member 5 and the second guide member 12 are both rollers to improve the smoothness of their movement in the guide groove. The main transmission wheel 15 is key-connected with the driving shaft 14, and the driving shaft 14 is transmission-connected with the active motor. The transmission belt 2 also passes around the auxiliary transmission wheel 16, and the support shaft 17 rotationally supports the auxiliary transmission wheel 16. One end of the support shaft 17 is fixedly connected to the first frame plate 3, and the other end is fixedly connected to the second frame plate 1. The second frame plate 1 is screwed with the adjusting screw 13. Guide columns are provided on the first and second frames. By controlling the rotation of the adjusting screw 13, the horizontal position of the entire pushing mechanism can be driven to adjust, which is adapted to the layout of the medicine plate pushing track.
[0018] The working principle of the utility model is: by driving the transmission belt 2 to move, the connecting seat 9 is driven to move, which can drive the push plate 7 to move and then push the medicine plate. When the connecting seat 9 moves to the main and auxiliary transmission wheels, the first guide groove 4 will transmit the first guide member 5 to move, and then drive the main swing arm 6 to swing, so that the push plate on the main swing arm 6 always remains in a vertical state, and when the main swing arm 6 swings, it will drive the connecting shaft 8 to rotate, and then drive the auxiliary swing arm 10 to swing synchronously, so that the push plate on the auxiliary swing arm 10 also remains in a vertical state, and the medicine plate is stably pushed to the boxing station of the packaging machine.
[0019] The structure of the utility model, by hingedly installing a swing arm with a push plate on a connecting seat, and cooperating with a first guide groove to guide the swing of the swing arm, enables the push plate to always maintain a vertical state, ensures that the push plate pushes and contacts the medicine plate in a consistent direction, and effectively improves the stability and accuracy of pushing the medicine plate.
