The planetary gear assembly 1 includes a drive motor (not shown), a first gear set 11 and a second gear set 12, the first gear set 11 including a carrier 111 and an internal gear 112 and a first gear shaft 113 meshed with each other, the axial direction of the internal gear 112 being perpendicular to the first plane. The driving motor is connected to the planet carrier 111 in a transmission way, the planet carrier 111 is used for driving the first gear shaft 113 to rotate around the axial direction of the internal gear 112 and rotate around the axial direction of the internal gear, the input end of the second gear set 12 is connected to the first gear set 11 in a transmission way, the output end of the second gear set 12 is connected to the connecting piece 22, and the first gear set 11 is used for driving the second gear set 12 to act, so that the pushing surface 211 is always parallel to the first direction, that is, the pushing piece 21 is always kept in a vertical state, and therefore the surface contact with the cigarette packet 10 can be achieved. The axial direction of the connecting member 22 and the axial direction of the first gear shaft 113 are parallel to each other and are not collinear, the axial direction of the connecting member 22 is perpendicular to the first plane, when the first gear shaft 113 rotates around the axial direction of the internal gear 112, the connecting member 22 moves in the first plane along the third direction to push the tobacco bale 10 on the first conveying line 100 to the second conveying line 200, and the third direction, the first direction and the second direction are all arranged at an included angle.
According to the box body pushing device, the connecting piece 22 moves in the first plane along the third direction, and because the third direction and the first direction and the second direction are both arranged in an included angle, the movement of the connecting piece 22 has a split speed in the first direction and the second direction, the split speed in the first direction enables the pushing piece 21 to follow the tobacco bale 10 on the first conveying line 100 in the first direction, the position of the pushing surface 211 is matched with that of the tobacco bale 10, the pushing surface 211 and the tobacco bale 10 are approximately static in the first direction, the vertical friction force between the pushing piece 21 and the tobacco bale 10 is avoided, and the split speed in the second direction enables the pushing piece 21 to smoothly push the tobacco bale 10 to the second conveying line 200.

In order to achieve a driving connection between the first gear set 11 and the second gear set 12, the first gear set 11 further comprises a follower rod 114 (see fig. 3 and 4), the planet carrier 111 and the annulus gear 112 being coaxially arranged. One end of the follower rod 114 is fixedly connected to the planet carrier 111, the first gear shaft 113 is hinged to the planet carrier 111, and the follower rod 114 and the first gear shaft 113 are coaxially arranged. The second gear set 12 includes a follower wheel 121, a first transfer gear 122, and a second gear shaft 123, and the follower wheel 121 is fixedly connected to the output shaft of the first gear shaft 113, and moves along with the first gear shaft 113, that is, simultaneously rotates around itself in the axial direction and revolves around the internal gear 112 in the axial direction. The first transmission gear 122 and the second gear shaft 123 are both hinged to the follower wheel 121, and the first transmission gear 122 is fixedly connected to the other end, far away from the planet carrier 111, of the follower rod 114, and the first transmission gear 122 follows the follower rod 114 to revolve around the inner gear 112 in the axial direction. The second gear shaft 123 is fixedly connected to the connecting piece 22, the first transmission gear 122 is in transmission connection with the second gear shaft 123, and the second gear shaft 123 is fixedly connected with the connecting piece 22, so that when the follower 121 rotates around the axial direction of the inner gear 112, the planet carrier 111 drives the first gear shaft 113 at the same time, and further the first transmission gear 122 drives the second gear shaft 123 to rotate, and because the second gear shaft 123 simultaneously revolves around the axial direction of the inner gear 112 along with the follower 121, relative to the axial direction of the inner gear 112, the angular speed of the second gear shaft 123 is always zero, and further the angular speed of the connecting piece 22 is always zero, the pushing piece 21 always keeps a vertical state, and the pushing surface 211 is always parallel to the first direction.
In the above structure, the gear ratio of the first transfer gear 122 and the second gear shaft 123 is 2:3, and the gear ratio of the internal gear 112 and the first gear shaft 113 is 3:1.
The calculation process is as follows:
The transmission ratio is calculated by adopting a conversion mechanism method, and when the follower wheel 121 is fixed, the transmission ratio from the first transmission gear 122 to the second gear shaft 123 is as follows:
In the above formula, since the follower wheel 121 and the first gear shaft 113 are fixedly connected, the first transfer gear 122 is fixedly connected to the carrier 111 through the follower rod 114, and thus ω 121＝ω113,ω122＝ω111. In operation of the first gear set 11, ω 113＝-2ω111 is provided when the tooth ratio of the internal gear 112 and the first gear shaft 113 is 3:1. The requirement to achieve ω 123 =0 can be derived 123 =3/2. That is, the gear ratio of the first transmission gear 122 and the second gear shaft 123 is 2:3, and the rotation directions of the first transmission gear 122 and the second gear shaft 123 are the same.
In order to achieve the same rotation direction of the first transmission gear 122 and the second gear shaft 123, the second gear set 12 further includes a second transmission gear 124, and the second transmission gear 124 is hinged to the follower wheel 121. The second transmission gear 124 is simultaneously engaged with the first transmission gear 122 and the second gear shaft 123, and the first transmission gear 122 and the second gear shaft 123 are identical in steering through intermediate transmission of the second transmission gear 124.
As shown in fig. 5, in operation of the first gear set 11, the first gear set 11 is a planetary gear train composed of a carrier 111, an internal gear 112, and a first gear shaft 113. Since the follower wheel 121 is fixedly connected to the output shaft of the first gear shaft 113, and the second gear shaft 123 is hinged to the follower wheel 121, the position of the center of the second gear shaft 123 can be simplified to be a certain point M on the first gear shaft 113, in fig. 5, a represents the axis of the internal gear 112, B represents the axis of the first gear shaft 113, and M is eccentrically disposed with respect to the axial direction of the first gear shaft 113. The first gear shaft 113 serves as a planetary gear, and the movement trace of a certain point M thereon is a regular polygon. When the gear ratio of the internal gear 112 to the first gear shaft 113 is 3:1, the movement locus of M is approximately triangular, that is, the movement locus of the connecting member 22 in the first plane is approximately triangular. In order to match the mutually perpendicular positional relationship of the first conveying line 100 and the second conveying line 200, the position of the point M relative to the point B is adaptively adjusted, so that on one hand, the movement track of the point M is approximately equilateral triangle, and on the other hand, the positions of the approximately equilateral triangle on the first plane relative to the first conveying line 100 and the second conveying line 200 are changed, so that when the connecting piece 22 moves along the side length of the approximately equilateral triangle, the positions and the conveying speeds of the first conveying line 100 and the second conveying line 200 can be matched.
Specifically, as shown in fig. 6, the movement track of the connecting member 22 in the first plane is an approximately equilateral triangle, which includes a first side 221, a second side 222, and an included angle between the first side 221 and the second side 222, and the position of the point M relative to the point B is adjusted so that the included angle faces the second conveying line 200. The arrow in fig. 6 indicates the direction of movement of the connecting element 22, which, when the connecting element 22 is moved along the first edge 221 to move the pushing element 21 towards the direction towards the second conveyor line 200, is brought into abutment with the packets 10 on the first conveyor line 100 and pushes the packets 10 to the second conveyor line 200 during the movement of the connecting element 22 along the first edge 221. When the connecting member 22 moves along the second edge 222, the pushing member 21 moves away from the second conveying line 200, and a pushing action is completed. The link 22 is cyclically moved along the approximately equilateral triangle and the next pushing action is effected during the next movement along the first side 221.
In one embodiment, the first gear set 11 further includes a frame 115 and a first cover 116. The frame 115 has a first side board 1151, the internal gear 112 is connected to the frame 115, the first side board 1151 is enclosed on the peripheral side of the internal gear 112, a first mounting hole is formed on the first cover board 116, the first cover board 116 is rotatably covered on the first side board 1151, and a first shaft end 1131 of the first gear shaft 113 passes through the first mounting hole to connect with an input end of the second gear set 12. In the rotation and revolution process of the first gear shaft 113, the first cover plate 116 is always covered on the first side coaming 1151, so as to provide protection, and prevent dust and impurities from entering the first gear set 11 to affect the transmission precision.
Likewise, the perimeter of follower wheel 121 has a second surrounding plate 1211 and second gear set 12 further includes a second cover plate 125. The second cover plate 125 is provided with a second mounting hole, the second cover plate 125 is covered on the second side wall plate 1211, and the connecting piece 22 passes through the second mounting hole to be connected to the second shaft end 1231 of the second gear shaft 123. While the connecting piece 22 rotates along with the second gear shaft 123, the second cover plate 125 is always covered on the second side wall 1211, so that dust and impurities are prevented from entering the second gear set 12 to affect the transmission precision.
As shown in fig. 2, the first gear shaft 113, the second gear set 12 and the pushing assembly 2 are all provided with two groups, the planet carrier 111 extends along the radial direction of the internal gear 112, the two first gear shafts 113 are symmetrically hinged at two ends of the planet carrier 111, and the two groups of the second gear set 12 and the two groups of the pushing assembly 2 respectively correspond to the two first gear shafts 113. Thus, through the action of the planet carrier 111, the motion control of the two groups of pushing assemblies 2 can be simultaneously realized, and the two pushing members 21 of the two groups of pushing assemblies 2 are arranged along the circumferential direction of the inner gear 112 at intervals and sequentially push the adjacent cigarette packets 10 on the first conveying line 100 respectively, so that the pushing efficiency is further improved.
