[0033] like Figure 1-Figure 5 As shown, the pushing device of the blister cartoning machine includes a chain 1, a sprocket (not shown), an annular push plate guide 4, an annular paper push guide and a plurality of pushing units 2. Each pushing unit 2 includes a pushing seat 20, a push plate assembly 21 and a paper push assembly 22. The push plate assembly 21 and the paper push assembly 22 are both mounted on the pushing seat 20, and the pushing seat 20 is connected to the chain 1, and the chain 1 is wound around the sprocket. Through the transmission of the main power source, the sprocket drives the chain 1 to rotate, and the chain 1 drives the pushing unit 2 to make an annular motion. In order to reduce the load of the chain 1, the present invention is provided with annular guide rails 3 on both sides of the annular push plate guide 4, and both ends of the pushing seat 20 are provided with movable slides 23, and the movable slides 23 are arranged on the annular guide rails 3 in a sliding manner. The "sliding in a sliding manner" here means that the movable slide 23 can make an annular motion on the annular guide rail 3. Through this structure, the weight of the entire pusher unit 2 acts on the annular guide rail 3. In other words, the annular guide rail 3 bears the weight of the entire pusher unit 2, and the chain 1 only needs to pull the entire pusher unit 2 to perform annular motion. Therefore, the noise of the entire system is significantly reduced, and the service life of the chain 1 is greatly extended.

[0034] There are two types of annular guide rails 3, and correspondingly, there are two types of structures of movable slide seat 23. Two specific embodiments are given below.

[0035] The first type: the annular guide rail 3 can be in the form of a groove. In this case, the movable slide 23 can be only a roller, allowing a roller to roll in the annular groove. The groove is preferably located on the side, allowing the roller to enter the groove from the side. This structure can also enable the movable slide 23 to slide on the annular guide rail 3 to achieve the same technical effect.

[0036] The second type: the annular guide rail 3 is in a strip shape. In this case, the movable slide 23 includes an upper roller 230 and a lower roller 231. Figure 5 and 9As shown, the lower roller 231 and the upper roller 230 hold the annular guide rail 3 inside and outside, that is, the lower roller 231 acts on the inner ring of the annular guide rail 3, and the upper roller 230 acts on the outer ring of the annular guide rail 3, so that the movable slide 23 will not move inside or outside; and the movable slide 23 at one end also includes a left roller and a right roller 232, and the left roller and the right roller 232 hold the annular guide rail 3 from left to right, that is, the left roller acts on the left side of the annular guide rail 3, and the right roller 232 acts on the right side of the annular guide rail 3, so that the movable slide 23 will not move left to right. This structure can also make the movable slide 23 cooperate with the sliding arrangement on the annular guide rail 3 to achieve the same technical effect.

[0037] On the basis of the second annular guide rail 3, in order to improve the stability of the engagement between the movable slide 23 and the annular guide rail 3, the annular guide rail 3 of the present invention has two annular guide rails 3 arranged side by side, such as Figure 8 The movable slide 23 has two upper rollers 230 disposed front and rear, as shown Fig. 9 As shown, the two upper rollers 230 act on the two annular guide rails 3, one on the left and one on the right. Figure 5 As shown, two upper rollers 230 and one lower roller 231 form a triangle when viewed from the side. The advantages of this structure of the movable slide 23 are: 1. The two upper rollers 230 can increase the contact area between the movable slide 23 and the annular guide rail 3, so that the force borne by each upper roller 230 can be shared, thereby reducing the friction between each upper roller 230 and the annular guide rail 3, and finally reducing the system noise and improving the life of the movable slide 23; 2. The two upper rollers 230 are arranged front and back so that the movable slide 23 can hold the annular guide rail 3 in the form of a triangle, and the three points form a surface, so that the movable slide 23 can more stably realize turning in the arc section of the annular guide rail 3. Based on the movable slide 23 of the above structure, according to the conjugate cam principle, in order to enable the movable slide 23 to realize smooth turning (that is, in the turning section, the two upper rollers 230 and the one lower roller 231 are always in contact with the annular guide rail 3), the surfaces of the turning transition sections 30 of the two annular guide rails 3 have a height difference. Through this structure, the movable slide 23 always holds the annular guide rail 3 in the turning section, so that the movement trajectory of the center point of the movable slide 23 in the turning section is infinitely close to a semicircle, so that the movement trajectory of the pusher unit 2 is infinitely close to a runway type, ultimately ensuring the stable operation of the pusher unit 2.

[0038] As described above, the chain 1 pulls the pusher unit 2 to move. However, as time goes by, the chain 1 will be slowly stretched. As the chain 1 stretches, the chain 1 will not be able to push the pusher unit 2 to work normally. In order to solve this problem, Figure 6As shown, the pusher seat 20 is connected to the chain 1 through the adaptive member 11, one end of the adaptive member 11 is hinged to the axle pin 10 of the chain 1, and the other end of the adaptive member 11 is hinged to the pusher seat 20 (including direct hinge or indirect hinge, Figure 6 The middle picture is hinged on a connecting seat, and the connecting seat is connected to the pusher seat 20). The advantage of this structure is that even if the chain 1 has a certain stretch, since the pusher seat 20 is limited on the annular guide rail 3, the pusher seat 20 can pull the adaptive member 11, and the adaptive member 11 pulls the chain 1, thereby ensuring that the chain 1 can normally push the pusher unit 2 to work, and finally ensuring that the pusher plate roller 44 will not fall off the annular pusher plate guide rail 4 when turning.

[0039] At present, when the pusher device of the mainstream blister cartoning machine on the market changes specifications (the heights of blister plates of different specifications will be different), the height of the paper pusher for pushing the instruction manual must also change accordingly. The existing structure can only support the adjustment or replacement of a single paper pusher assembly 22 one by one, which is time-consuming and labor-intensive, and it is difficult to unify the adjustment height, which in turn affects the pushing of materials into the box.

[0040] In order to solve this problem, the present invention provides a guide groove frame 5 on the periphery of the annular push plate guide rail 4, such as 1 and Figure 2 As shown, the guide groove frame 5 is provided with an annular paper pushing guide groove 52 and an annular lifting guide groove 53. Fig.11 As shown, the guide groove frame 5 is assembled by an upper guide groove frame 50 and a lower guide groove frame 51, and the upper guide groove frame 50 is installed on the lower guide groove frame 51 in a manner that it can be raised and lowered. The upper guide groove frame 50 has an annular paper pushing guide groove upper section 521 and an annular lifting guide groove upper section 531, and the lower guide groove frame 51 has an annular paper pushing guide groove lower section 522 and an annular lifting guide groove lower section 532. The annular paper pushing guide groove upper section 521 and the annular paper pushing guide groove lower section 522 can be extended and connected, and the annular lifting guide groove upper section 531 and the annular lifting guide groove lower section 532 can be extended and connected: that is, when the upper guide groove frame 50 is raised and lowered, the distance between the annular paper pushing guide groove upper section 521 and the annular paper pushing guide groove lower section 522 changes, but the two still form a closed loop, and the same is true for the annular lifting guide groove upper section 531 and the annular lifting guide groove lower section 532.

[0041] After adopting the above-mentioned guide groove frame 5 structure, in order to enable the paper pushing assembly 22 to adapt to the guide groove frame 5, the structure of the pushing unit 2 should also be improved accordingly. The specific improvements are as follows: Fig. 9 As shown, a lifting guide rail 24 is installed on the pusher seat 20. Fig.10As shown, a positioning slider 25 is slidably provided on the lifting guide rail 24, and a lifting roller 26 and a positioning guide groove 27 are installed on the positioning slider 25, and the lifting roller 26 is arranged in the annular lifting guide groove 53; the paper pushing assembly 22 includes a paper pushing board 220 and a paper pushing guide rod 221, one end of the paper pushing guide rod 221 is connected to the paper pushing board 220, and the other end of the paper pushing guide rod 221 is connected to the paper pushing roller 222, the paper pushing guide rod 221 is arranged in the positioning guide groove 27, and the positioning guide groove 27 guides the paper pushing guide rod 221, and the paper pushing roller 222 is arranged in the annular paper pushing guide groove 52.

[0042] The height adjustment principle of the push paper board 220 is as follows: when the height of the medicine board increases, the height of the push paper board 220 also increases accordingly. When adjusting, the upper guide slot frame 50 is raised, and the annular paper push guide slot upper section 521 and the annular lifting guide slot upper section 531 are raised at the same time. Since the lifting roller 26 is in the annular lifting guide slot 53, the positioning slider 25 moves and rises on the lifting guide rail 24, and the positioning guide slot 27 is also raised at the same time. Since the paper push roller 222 is arranged in the annular paper push guide slot 52, the paper push guide rod 221 and the push paper board 220 are also raised at the same time, so that the paper push guide rod 221 is still in the positioning guide slot 27, and the push paper board 220 can adapt to the height of the medicine board after being raised. In this way, it is very simple to adjust the height of the push paper board 220, as long as the height of the upper guide slot frame 50 is adjusted, thereby reducing the difficulty of adjusting the equipment after changing the specifications of the medicine board and improving production efficiency.

[0043] The extendable connection between the upper section 521 of the annular paper pushing guide groove and the lower section 522 of the annular paper pushing guide groove can adopt a variety of structures, such as a stretchable extension guide groove, which is used to connect the upper and lower sections. The present invention provides a more convenient connection method: Fig.11 As shown, the end of the annular paper pushing guide groove upper section 521 has a vertical guide groove extension 54, and the end of the annular paper pushing guide groove lower section 522 has a vertical connection adjustment groove 55, and the guide groove extension 54 is arranged in the connection adjustment groove 55 in a manner that it can be raised and lowered. When the height of the upper guide groove frame 50 is adjusted, the guide groove extension 54 on the upper guide groove frame 50 moves vertically up and down in the connection adjustment groove 55 on the lower guide groove frame 51, while the annular paper pushing guide groove 52 is still a closed guide groove.

[0044] Similarly, the extendable connection between the upper section 531 of the annular lifting guide groove and the lower section 532 of the annular lifting guide groove can adopt a variety of structures. Since the annular lifting guide groove 53 is slotted along the horizontal direction, an extension block that can move up and down can be used on the side to connect the upper and lower sections through the extension block; the present invention provides a more convenient connection method: Fig.11 and Fig.12As shown, the end of the annular lifting guide groove upper section 531 has a vertical upper guide groove side wall 533, and the end of the annular lifting guide groove lower section 532 has a vertical lower guide groove side wall 534, and the lower guide groove side wall 534 is aligned with the upper guide groove side wall 533. When the height of the upper guide groove frame 50 is adjusted, although the upper guide groove side wall 533 on the upper guide groove frame 50 and the lower guide groove side wall 534 on the lower guide groove frame 51 are changed in vertical distance, the two are still attached together, and the lifting roller can still be on the upper guide groove side wall 533 or the lower guide groove side wall 534, that is, the annular lifting guide groove 53 is still a closed guide groove.

[0045] In order to more stably adjust the position of the upper guide slot frame 50, the present invention installs a lifting slider seat 511 on the lower guide slot frame 51, the upper guide slot frame 50 is installed with a linear guide rail 501, and the lifting slider seat 511 is slidably arranged on the linear guide rail 501, and an adjusting screw 58 is also installed on the lower guide slot frame 51, and the adjusting screw 58 is threadedly connected with the upper guide slot frame 50. When the position of the upper guide slot frame 50 needs to be adjusted, the upper guide slot frame 50 is moved up and down through the linear guide rail 501 by rotating the adjusting screw 58 (either manually or by a motor), thereby achieving smooth adjustment.

[0046] Of course, the push plate assembly 21 includes a push plate head 210, a push plate roller 212 and a push plate slider 211. Fig. 9 As shown, the push plate roller 212 and the push plate head 210 are both connected to the push plate slider 211, the push plate roller 212 is located in the annular push plate guide rail 4, the push plate seat 20 is provided with a positioning guide rail 28, and the push plate slider 211 is slidably arranged on the positioning guide rail 28. As the push plate seat 20 makes an annular motion, the push plate roller 212 moves on the annular push plate guide rail 4, and under the guidance of the annular push plate guide rail 4, the push plate slider 211 moves on the positioning guide rail 28, so that the push plate head 210 realizes the action of pushing the medicine plate.

[0047] like Figure 7 and Fig.13As shown, under normal circumstances, the push plate roller moves along the path of the annular push plate guide rail 4. When the push plate roller 212 moves along the path, the push plate head 210 can push the medicine plate out normally; however, sometimes there is a problem with the placement of the medicine plate, resulting in no medicine plate in a certain grid in the medicine plate conveying grid. At this time, the push plate head 210 does not need to push it out. Of course, the push plate head 210 can also push it out, but since the process of pushing the push plate head 210 is the process of the push plate roller 212 walking on the ramp, this will affect the roller life. In order to solve this problem, a push plate protection guide groove 40 is provided on one side of the annular push plate guide rail 4, and both ends of the push plate protection guide groove 40 are connected to the annular push plate guide rail 4. A push plate track change assembly is provided at the connection between the push plate protection guide groove 40 and the upper end of the annular push plate guide rail 4. The push plate track change assembly includes a push plate track change branch 41 and a push plate track change power source that drives the push plate track change branch 41 to rotate. When the system detects that there is no medicine plate in a certain grid, the push plate track changing power source controls the push plate track changing fork 41 to rotate, so that the corresponding push plate roller 210 no longer enters the annular push plate guide rail 4, but enters the push plate protection guide groove 40. Since the push plate protection guide groove 40 has no ramp, it will not affect the push plate roller 210, thereby increasing the life of parts such as the roller.

[0048] Similarly, in order to extend the life of the paper pushing roller, a paper pushing protection guide groove 59 is provided on one side of the annular paper pushing guide groove 52. Fig.15 As shown, both ends of the paper pushing protection guide groove 59 are connected to the annular paper pushing guide groove 52, and a paper pushing track changing component is provided at the connection between the upper end of the paper pushing protection guide groove 59 and the annular paper pushing guide groove 59. Fig.14 As shown, the paper push track changing assembly includes a paper push track changing fork 590 and a paper push track changing power source for driving the paper push track changing fork 590 to rotate. Its principle is the same as the track changing of the above-mentioned push plate roller, and will not be repeated here.

[0049] According to a blister cartoning machine pushing device provided by the present invention, annular guide rails 3 are arranged on both sides of annular push plate guide rail 4, and movable slides 23 at both ends of a pushing seat 20 are slidably arranged on the annular guide rails 3, so that the annular guide rails 3 bear the weight of the entire pushing unit 2, and the chain 1 is only responsible for pulling the entire pushing unit 2 to move, so that the noise of the entire system is greatly reduced and the service life of the chain is extended.
