[0023] like Figure 1 As shown, the pushing device of the cartoning machine includes a support 1, a racetrack guide rail 2, a transmission mechanism 3 and a plurality of pushing units 4. The plurality of pushing units 4 are driven by the transmission mechanism 3 and guided by the racetrack guide rail 2 to push the instruction sheet and the medicine plate into the medicine box.

[0024] like Figure 4 As shown, the transmission mechanism 3 includes a chain 30, a sprocket and a power source (the sprocket and the power source are not shown). The chain 30 is wound around the sprocket, and the sprocket is driven by the power source to move. Figure 2 As shown, the pusher unit 4 includes a pusher seat 4A and a pusher plate assembly, the pusher plate assembly includes a pusher plate slide 42, a pusher plate head 43 and a pusher plate guide wheel 420, the pusher plate head 43 and the pusher plate guide wheel 420 are both mounted on the pusher plate slide 42, and the pusher plate slide 42 is slidably arranged on the pusher seat 4A; both ends of the pusher seat 4A have connecting blocks 40, and the inner side surface of the connecting block 40 has a groove, such as Figure 5 As shown, a swing block 48 with adjustable swing is provided in the groove. Figure 8 As shown, a compression spring 404 is provided in the connecting block 40, and the compression spring 404 presses on the swing block 48 from above or below, and the compression spring 404 can make the swing block 48 realize elastic swing, as shown in FIG. Figure 4 As shown, the chain 30 is connected to the swing block 48 via a chain pin.

[0025] The principle of the transmission mechanism 3 driving the pusher unit 4 to move is as follows: the power source drives the sprocket to rotate, and the sprocket drives the chain 30 to move. Since the chain 30 is connected to the swing block 48, and the swing block 48 is connected to the connecting block 40 of the pusher unit 4, when the chain 30 moves, it can drive the pusher unit 4 to move; when the pusher unit 4 comes to the turning point of the runway-type guide rail 2, since the swing block 48 has swinging space in the groove of the connecting block 40, the chain 30 can have a certain floating space relative to the connecting block 40 of the pusher unit 4, thereby ensuring that the connection relationship between the chain 30 and the connecting block 40 is not prone to failure, making the movement of the chain 30 more stable and the service life more lasting.

[0026] like Figure 6 and Figure 7As shown, the outer side of the swing block 48 is provided with a rotation pin 480, and the rotation pin 480 is rotatably arranged on the connecting block 40. The swing block 48 is rotated by the rotation pin 480.

[0027] like Figure 8 As shown, the connection block 40 comprises an upper connection block 401 and a lower connection block 402, the groove is located on the lower connection block 402, the bottom of the upper connection block 401 comprises a compression spring groove 403 for placing a compression spring 404, the lower connection block 402 comprises a through hole 405 for allowing the compression spring 404 to pass through, and the upper connection block 401 and the lower connection block 402 are connected by bolts. Dividing the connection block 400 into the upper connection block 401 and the lower connection block 402 can facilitate the installation of the compression spring 404 and the processing of the compression spring groove 403.

[0028] like Figure 2 As shown, the pusher seat 4A further includes two parallel guide rods 41 , and the push plate slide 42 is slidably disposed on the two guide rods 41 , and the guide rods 41 are connected to the upper connecting block 401 .

[0029] like Fig. 9 As shown, the inner side of the support 1 has a racetrack-shaped groove 10, and the connecting block 40 of the pusher seat 4A is connected with two rollers 46, and the rollers 46 are located in the racetrack-shaped groove 10. When the chain 30 drives the pusher unit 4 to move, the two rollers 4 move in the racetrack-shaped groove 10 of the support 1, so that the pusher unit 4 can stably move along the racetrack-shaped track. It is worth mentioning here that since the position of the chain 30 is fixed (because the chain 30 is wound around the sprocket), the chain 30 floats the connecting block 40 through the swing block 48 and the compression spring 404, so that the two rollers 46 on the connecting block 40 can move closely on the top surface of the racetrack-shaped groove 10 (just like the wheels of a car walking closely on the ground), and will not move up and down in the racetrack-shaped groove 10 and shake, so that the pusher unit 4 moves more smoothly and with lower noise.

[0030] like Figure 2 and Figure 3 As shown, the material pushing unit 4 includes a paper pushing assembly, which includes a paper pushing slide 44, a paper pushing head 45 and a paper pushing guide wheel 440. The paper pushing head 45 and the paper pushing guide wheel 440 are both installed on the paper pushing slide 44, and the paper pushing slide 44 is slidably arranged on the material pushing seat 4A. The working principle of the paper pushing assembly is the same as that of the push plate assembly: Fig.10As shown, when the pushing unit 4 moves, the paper pushing guide wheel 440 moves in the paper pushing guide groove 21 of the racetrack guide rail 2, and the push plate guide wheel 420 moves in the push plate guide groove 20 of the racetrack guide rail 2; thus, the paper pushing slide 44 can slide on the guide rod 41, so that the paper pushing head 45 pushes the instruction sheet forward, and the push plate slide 42 also slides on the guide rod 41, so that the push plate head 43 pushes the medicine sheet forward. Of course, some paper boxes do not need to place the instruction sheet, so the paper pushing assembly may not be needed.

[0031] In order to prevent the medicine plate from bending when being pushed forward (during the pushing process, the front end of the medicine plate will be resisted by the paper box and the instruction manual), the paper pushing head 45 is connected to the front end of the swing rod 441, the middle part of the swing rod 441 is hinged on the paper pushing slide 44, and the rear end of the swing rod 441 is connected to the material pressing guide wheel 47; the support 1 is connected to the material pressing guide plate 5, and the material pressing guide plate 5 is located above the material pushing unit 4. When the material pressing guide wheel 47 passes under the material pressing guide plate 5, the front end of the swing rod 441 can be swung up, and the paper pushing slide 44 is provided with a spring 442 for returning the front end of the swing rod 441 to the downward swing. When the paper pushing head 45 and the plate pushing head 43 start to push the material forward, the pressing guide wheel 47 passes under the pressing guide plate 5. At this time, the paper pushing head 45 is in an upward swing state. When the paper pushing head 45 and the plate pushing head 43 are pushed to a certain distance, the pressing guide wheel 47 is no longer restricted by the pressing guide plate 5. In this way, under the action of the spring 442, the paper pushing head 45 swings down and presses onto the medicine plate to prevent the medicine plate from bending when being pushed forward, thereby ensuring the quality of the medicine plate.

[0032] Finally, it is worth mentioning that there are two compression springs 404, and both compression springs 404 are pressed on the swing block 48 from above or below. The two compression springs 404 can give twice the elastic force, which can make the two rollers 46 on the connecting block 40 tightly attached to the top surface in the racetrack groove 10.
