Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] refer to Figure 1-6An automatic cartoning machine for injectable drug production is shown, comprising a conveyor base plate 2 and an inner tray conveyor belt 13. Multiple sets of conveyor base plates 2 are provided, and adjacent conveyor base plates 2 are connected by cartoning conveyor belts 3. The conveyor base plates 2 are fixed by support legs 1. A drive motor 5 for driving the cartoning conveyor belts 3 is also provided on the conveyor base plate 2. The conveyor base plate 2 has a partition plate with the same shape as the cartoning conveyor belt 3 and slides on the surface of the cartoning conveyor belt 3. The partition plate divides the cartoning conveyor belt 3 into two parts: one side for conveying medicine boxes and the other side for conveying inner trays. The conveyor base plate 2 and the inner tray conveyor belt 13 are connected by a mounting plate 12. The conveyor base plate 2 is equipped with a transfer mechanism for transferring the inner tray containing the injection vial from the inner tray conveyor belt 13 to the carton conveyor belt 3. The conveyor base plate 2 also has a medicine box loading port 6 for rapid loading of medicine boxes. The medicine box loading port 6 is located above the side of the carton conveyor belt 3 that carries the medicine boxes. To accommodate medicine boxes and inner trays of different sizes, the conveyor base plate 2 has triangular blocks 8 and opening mechanisms 15 on both sides. The opening mechanisms 15 correspond to the positions of the medicine box loading port 6, and the triangular blocks 8 correspond to the positions of the transfer mechanism. The partition plate has centering mechanisms 4 on both sides facing opposite directions. Both the triangular blocks 8 and the opening mechanisms 15 are used to open the centering mechanisms 4. The centering mechanism 4 has multiple sets, which are equidistantly arranged on the boxing conveyor belt 3. The centering mechanism 4 also includes a medicine box baffle 41, a clamping plate 42, and a spring telescopic rod 44. The clamping plate 42 has multiple sets and is located on both sides of the medicine box baffle 41. The fixed end of the spring telescopic rod 44 is installed in the medicine box baffle 41, and the output end of the spring telescopic rod 44 is connected to the clamping plate 42. The clamping plate 42 is connected to a connecting rod 43. The connecting rods 43 on both sides of the partition plate correspond to the positions of the triangular block 8 and the opening mechanism 15, respectively. In order to avoid the spring telescopic rod 44 from damaging the inner tray or medicine box due to excessive force, the spring telescopic rod 44 uses a spring with low elasticity. The conveyor base plate 2 is also equipped with The inner tray is pushed by an inner tray propulsion mechanism 14, which is located on the same side of the conveyor base plate 2 as the triangular block 8. In order to facilitate and stabilize the transfer of the inner tray from the inner tray conveyor belt 13 to the carton conveyor belt 3, the transfer mechanism also includes a rotating arm 7. The mounting plate 12 is connected to a fixed plate through the rotating arm 7. The mounting plate 12 is connected to a feeding motor 9 for driving the rotating arm 7. The fixed plate is provided with a control cylinder 10. The control cylinder 10 passes through the fixed plate and is connected to a gripper 11, so that the equipment can control the gripper 11 to hold the inner tray through the control cylinder 10. The rotating arm 7 is driven by the feeding motor 9, so that the gripper 11 moves between the carton conveyor belt 3 and the inner tray conveyor belt 13.

[0024] As one embodiment of this invention, to facilitate feeding when the medicine box is clamped and fixed by the centering mechanism 4, the opening mechanism 15 further includes a third electric push rod 151 and a lever 153. The lever 153 is rotatably connected to the conveying base plate 2. The bottom of the lever 153 has teeth, and a rack 152 meshes with the bottom of the lever 153. The rack 152 is connected to the telescopic end of the third electric push rod 151. The third electric push rod 151 is mounted on the conveying base plate 2, so that the device can push or pull the rack 152 through the third electric push rod 151. The two sets of third electric push rods 151 respectively drive the lever 153 meshing with the corresponding rack 152 to rotate, so that the lever 153 will center. In mechanism 4, the connecting rod 43 moves, and multiple sets of levers 153 are provided. The distance between adjacent levers 153 is the same as the distance between the two sets of centering mechanisms 4. The positions of levers 153 and connecting rods 43 are corresponding. The levers 153 between the two sets of centering mechanisms 4 are set facing each other. The two sets of levers 153 separate the connecting rods 43 to both sides, so that the medicine box can be placed more conveniently between the centering mechanisms 4. Similarly, multiple sets of triangular blocks 8 are provided on the other side of the conveying base plate 2. The position and size of the triangular blocks 8 are adapted to the gripper 11. The triangular blocks 8 are connected to the first electric push rod 81 through the sliding block 82. The first electric push rod 81 is installed on the conveying base plate 2, so that the inner tray can be placed more conveniently between the centering mechanisms 4.

[0025] As one embodiment of this invention, in order to allow the inner tray to be more accurately inserted into the inner tray pushing mechanism 14, an L-shaped plate 141 and a second electric push rod 143 are also included. The second electric push rod 143 is mounted on the conveying base plate 2 through the L-shaped plate 141. The output end of the L-shaped plate 141 passes through the L-shaped plate 141 and is connected to a locking block 144. The top plate 142 has a through hole that matches the size of the second electric push rod 143. The top plate 142 is slidably connected to the second electric push rod 143. The top plate 142 has a groove that matches the locking block 144. The top plate 142 is connected to the L-shaped plate 141 through an elastic telescopic rod. The top plate 142 is provided with a magnet for connecting with the locking block 144. Both the top plate 142 and the clamping plate 42 are provided with anti-slip textures to prevent interference from the centering mechanism 4 when the second electric push rod 143 is retracted.

[0026] The working principle of this product is as follows: During the cartoning process of the injection solution, the worker or other equipment fills the injection solution into the plastic inner tray. Then, the inner tray is conveyed to the transfer mechanism by the inner tray conveyor belt 13. The control cylinder 10 in the transfer mechanism drives the gripper 11 to clamp the inner tray. Then, the feeding motor 9 is started, which drives the rotating arm 7 to move, causing the gripper 11 to transfer the inner tray from the inner tray conveyor belt 13 to the cartoning conveyor belt 3. During the transfer, the servo motor installed on the rotating arm 7 in the transfer mechanism controls the fixing plate to maintain balance, so that the inner tray is smoothly transferred from the inner tray conveyor belt 13. The contents are transported to the cartoning conveyor belt 3. Then, the first electric push rod 81 is activated, pushing the sliding block 82 upward. This causes the triangular block 8 on the sliding block 82 to contact the centering mechanism 4 on the cartoning conveyor belt 3. The triangular block 8 presses the connecting rod 43 towards the medicine box baffle 41. The connecting rod 43 drives the clamping plate 42 to move, allowing the inner tray to be easily transferred between two adjacent centering mechanisms 4 via the transfer mechanism. After the transfer is completed, the first electric push rod 81 is driven in the reverse direction to reset the triangular block 8 via the sliding block 82. At the same time as transferring the inner tray, the medicine box is fed from the medicine box loading port 6. The medicine box is placed in the equipment, allowing it to fall onto the boxing conveyor belt 3 under gravity. Simultaneously, the third electric push rod 151 drives the rack 152 to rotate the lever 153, pressing the connecting rod 43 in the centering mechanism 4 towards the medicine box baffle 41. Both sets of third electric push rods 151 operate simultaneously, moving the connecting rods 43 of adjacent centering mechanisms 4 in opposite directions, allowing the medicine box to easily fall between the centering mechanisms 4. The lever 153 is then reset by reversing the third electric push rod 151. Afterward, the medicine box and inner tray are moved by the boxing conveyor belt 3. The contents are delivered to the inner tray propulsion mechanism 14, and the second electric push rod 143 is activated to push the locking block 144 to move. The top plate 142, which is connected to the locking block 144 by a magnet, moves synchronously. The locking block 144 pushes the inner tray held between the two sets of centering mechanisms 4 into the medicine box. At the same time, the top plate 142 comes into contact with the clamping plate 42. Because both the top plate 142 and the clamping plate 42 are provided with anti-slip textures, the position of the clamping plate 42 is easily fixed and will not interfere with the locking block 144 when returning, thus avoiding the problem of jamming. After that, the medicine box after filling is output through the boxing conveyor belt 3.
