[0015] like Figure 1As shown, the annular material pushing guide includes a material pushing track changing assembly, which includes a track changing fork for the push plate roller 8 and the paper pushing roller 9 to pass through together and a track changing power source for driving the track changing fork to rotate. The track changing fork is driven by the track changing power source to rotate, thereby guiding the push plate roller 8 and the paper pushing roller 9 to the guide groove together.

[0016] The track-changing switch is arranged in the traveling guide groove 1, and a straight protection guide groove 2, a first oblique pushing guide groove 3 and a second oblique pushing guide groove 4 are branched out at one end of the traveling guide groove 1. The entrance of the straight protection guide groove 2, the entrance of the first oblique pushing guide groove 3 and the entrance of the second oblique pushing guide groove 4 are all located in front of the track-changing switch, and the exit of the straight protection guide groove 2, the exit of the first oblique pushing guide groove 3 and the exit of the second oblique pushing guide groove 4 converge at the other end of the traveling guide groove 1. In this way, the track-changing switch can guide the push plate roller 8 and the paper pushing roller 9 into the straight protection guide groove 2 and the first oblique pushing guide groove 3 at the same time, or into the first oblique pushing guide groove 3 and the second oblique pushing guide groove 4 at the same time, and then return to the traveling guide groove 1, and perform a cyclic motion. As for the function of each guide groove, it is described in detail below. As Figure 4 As shown, a first partition 6 is provided between the straight protection guide groove 2 and the first oblique material pushing guide groove 3 , and a second partition 7 is provided between the first oblique material pushing guide groove 3 and the second oblique material pushing guide groove 4 .

[0017] The paper pushing assembly includes a paper pushing head and a paper pushing roller 9, and the movement of the paper pushing head is controlled by guiding the paper pushing roller 9; the pushing plate assembly includes a pushing plate head and a pushing plate roller 8, and the movement of the pushing plate head is controlled by guiding the pushing plate roller 8. Under normal circumstances, when the pushing plate roller 8 and the paper pushing roller 9 move in the first oblique pushing guide groove 3 and the second oblique pushing guide groove 4 respectively (if the pushing plate roller 8 is in the first oblique pushing guide groove 3, the paper pushing roller 9 is in the second oblique pushing guide groove 4; if the pushing plate roller 8 is in the second oblique pushing guide groove 4, the paper pushing roller 9 is in the first oblique pushing guide groove 3), the pushing plate head can push out the medicine board, and the paper pushing head can push out the instruction manual; however, sometimes there is a problem with the placement of the medicine board, resulting in no medicine board in a certain grid in the medicine board conveying grid, and at this time, the pushing plate head does not need to push out; there is no medicine board and no instruction manual, so the paper pushing head does not need to push out. Of course, the plate pusher head and the paper pusher head can also be pushed out, but the process of pushing out is the process that the plate pusher roller 8 and the paper pusher roller 9 walk on the ramp, which will affect the life of the rollers.

[0018] The annular push guide rail of the present invention solves the problem that when the system detects that there is no medicine plate in a certain grid, Figure 2 and Figure 5As shown, the track change power source controls the rotation of the track change fork, controls the push plate roller 8 and the paper push roller 9 to enter the straight protection guide groove 2 and the first oblique material pushing guide groove 3 respectively. Since the push plate roller 8 and the paper push roller 9 have a height difference, assuming that the height of the paper push roller 9 is higher than that of the push plate roller 8, then the push plate roller 8 is located in the straight protection guide groove 2, and the paper push roller 9 is located above the first oblique material pushing guide groove 3. At this time, the push plate roller 8 walks in a straight line in the straight protection guide groove 2, and the paper push roller 9 can cross the first partition 6 and continue to move in a straight line. Since it does not enter the inclined road, but walks in a straight road, it will not affect the push plate roller 8 and the paper push roller 9, which can increase the life of the rollers and other parts. When normal pushing is required, such as Figure 3 and Figure 6 As shown, the track change power source controls the rotation of the track change fork, controls the push plate roller 8 and the paper push roller 9 to enter the first oblique material pushing guide groove 3 and the second oblique material pushing guide groove 4 respectively, and the push plate roller 8 runs an oblique line in the first oblique material pushing guide groove 3, thereby driving the push plate head to push the plate; and the paper push roller 9 runs an oblique line in the second oblique material pushing guide groove 4, thereby driving the paper push head to push the paper. Through this ingenious annular material pushing guide structure, the paper push guide function and the push plate guide function can be integrated together, and it also has the paper push protection function and the push plate protection function, which greatly reduces the control difficulty, reduces the equipment volume, reduces the manufacturing cost, and has a higher overall integration.

[0019] As described above, the paper pushing roller 9 can continue to move along a straight line beyond the first partition 6. In order to ensure that the paper pushing roller 9 moves stably along a straight line, the height of the second partition 7 is higher than the height of the first partition 6.

[0020] The present invention provides a side block 11 on the front side of the first partition 6, and a side walkway 10 is formed between the side block 11 and the upper surface of the first partition 6. The side walkway 10 and the entrance of the first oblique material pushing guide groove 3 are located on a straight line, and the side walkway 10 merges with the walking guide groove 1. After the paper pushing roller 9 comes over the first oblique material pushing guide groove 3, it passes over the first partition 6, and then comes to the side walkway 10 formed between the side block 11 and the upper surface of the first partition 6 along a straight line. With the assistance of the side block 11, the paper pushing roller 9 can stably move along a straight line, and finally enter the walking guide groove 1 again through the merge.

[0021] Based on such an annular pushing guide rail, the present invention also provides a pushing device for a cartoning machine. The pushing device for a cartoning machine includes a plurality of pushing units and the annular pushing guide rail described above; the pushing unit includes a pushing seat, a pushing plate assembly and a paper pushing assembly, the paper pushing assembly includes a paper pushing head and a paper pushing roller 9; the pushing plate assembly includes a pushing plate head and a pushing plate roller 8, the pushing plate roller 8 and the paper pushing roller 9 have a height difference, the higher roller can pass over the first partition 6, the higher roller can be in the second oblique pushing guide groove 4, the lower roller can be in the straight protection guide groove 2, and the lower roller can be in the first oblique pushing guide groove 3. The pushing principle and protection principle of the pushing device for a cartoning machine have been described in detail above, and will not be repeated here. By using this pushing device for a cartoning machine, the structure of the whole machine can be more compact, the procedure can be simpler, and the appearance can be more compact, which is very suitable for high-speed cartoning machines.
