In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0045] The present invention provides a tax ticket taking mechanism and a tax ticket sticking machine, such as Figure 1-7As shown, the tax invoice taking mechanism includes a ticket warehouse 1, a first driving member, a first planetary gear train and a suction nozzle 3. The ticket warehouse 1 is used to provide tax invoices; the first planetary gear train includes a fixed first internal gear 21, a first planetary carrier 23 and a plurality of planetary assemblies 22, each planetary assembly 22 includes a first planetary gear 221, a roller shaft 222 and a roller 223, the first planetary gear 221 is meshed with the first internal gear 21, and the first driving member can drive the first planetary gear 221 to rotate around the first internal gear 21; the roller shaft 222 is fixedly connected to the pitch circle of the first planetary gear 221, the roller 223 is rotatably connected to the roller shaft 222, the first planetary carrier 23 is radially provided with a slot 231, and the roller 223 is rotatably located in the slot 231; the first planetary carrier 23 can drive the suction nozzle 3 to rotate, and the suction nozzle 3 is used to absorb the tax invoice provided by the ticket warehouse 1. The tax ticket taking mechanism drives the first planetary gear 221 to rotate around the first internal gear 21 through the first driving member, the roller shaft 222 is fixedly connected to the pitch circle of the first planetary gear 221, the roller 223 is rotatably connected to the roller shaft 222, the first planetary carrier 23 is provided with a slot 231 in the radial direction, the first planetary gear 221 drives the roller 223 to rotate along the radial direction of the slot 231 and is located in the slot 231, so that when the first planetary gear 221 rotates around the first internal gear 21, the roller 223 rotates along the slot 231 with the first planetary gear 221 and makes a linear motion along the slot 231, so that the first planetary gear 221 rotates around the first internal gear 21 every time the first planetary gear 221 rotates. There is a state of near stop once in one rotation, and the first planetary carrier 23 can drive the suction nozzle 3 to rotate. When the first planetary gear 221 moves to a state of near stop, the suction nozzle 3 smoothly absorbs the tax ticket from the ticket library 1. Compared with the cam-gear-pinion bar combination transmission, there is no sudden change in the output speed and output acceleration of the first planetary gear 221, which can ensure that the suction nozzle 3 can smoothly absorb the tax ticket, with a simple structure, convenient maintenance, low production cost and high work efficiency. In addition, compared with the gear-rack combination transmission in the prior art, it can reduce the impact and wear of the gear on the gear caused by the tooth side clearance at the gear meshing point, and reduce the noise of the tax ticket taking mechanism.

[0046] Alternatively, if Figure 1-7As shown, the tax invoice taking mechanism also includes a second planetary gear train, which includes a first gear 41, a second planetary gear 42, a fixed second internal gear 43 and a second planetary carrier 44. The first planetary carrier 23 is fixed with a second gear 232, the second gear 232 is meshed with the first gear 41, the second planetary carrier 44 includes a first shaft 441 and a second shaft 442 connected to each other, the first gear 41 is fixed to the first shaft 441, the second planetary gear 42 is rotatably arranged on the second shaft 442, the second planetary gear 42 is meshed with the second internal gear 43, the central axis of the first shaft 441 and the central axis of the second shaft 442 are spaced apart, and the suction nozzle 3 is fixedly connected to one side of the second planetary gear 42. By fixing the second gear 232 on the first planetary carrier 23 and fixing the first gear 41 on the first shaft 441, the first driving member drives the first planetary gear 221 to rotate around the first internal gear 21, the roller shaft 222 is fixedly connected to the first planetary gear 221, and the roller 223 is rotatably connected to the roller shaft 222, so that the roller 223 rotates around the first internal gear 21 with the first planetary gear 221 and moves linearly along the radial direction of the slot 231, so as to drive the first planetary carrier 23 to rotate, and the second gear 232 is fixed to the first planetary carrier 23 to drive the second gear 232 to rotate. The second gear 232 is meshed with the first gear 41, and the second planetary gear 42 is rotatably connected to the second shaft 442, thereby driving the second planetary gear 42 to rotate around the second internal gear 43, wherein the second planetary carrier 44 is rotatably connected to the frame 10. It can be understood that the central axis of the first gear 41 and the central axis of the second planetary gear 42 are spaced apart, the second planetary gear 42 is meshed with the second internal gear 43, and the suction nozzle 3 is fixedly connected to one side of the second planetary gear 42 so that the suction nozzle 3 can be aligned with the ticket warehouse 1 and absorb the tax ticket, and the suction nozzle 3 is away from the first gear 41 relative to the second planetary gear 42.

[0047] A tax stamp machine, such as Figure 1 As shown, it includes the above-mentioned tax invoice taking mechanism, and the tax invoice sticking machine also includes a second driving member, a first rotating shaft 51 and a posting wheel 511 fixedly connected to the first rotating shaft 51, the second driving member is drivingly connected to the first rotating shaft 51, and the suction nozzle 3 can transfer the tax invoice to the posting wheel 511. By setting the posting wheel 511, the second driving member is drivingly connected to the first rotating shaft 51, and the posting wheel 511 is fixedly connected to the first rotating shaft 51, so that the second driving member drives the posting wheel 511 to rotate and be tangent to the suction nozzle 3, so as to transfer the tax invoice to the posting wheel 511. Among them, after the suction nozzle 3 sucks the tax invoice, the suction nozzle 3 continues to rotate and transfers the tax invoice to the posting wheel 511. At this time, the rotation speed of the suction nozzle 3 is between two approximately resting states. By setting the rotation radius of the posting wheel 511, the rotation speed of the suction nozzle 3 can be close to or even the same as the rotation speed of the posting wheel 511, so as to realize the smooth transfer of the tax invoice to the posting wheel 511.

[0048] Alternatively, if Figure 1As shown, the tax stamp pasting machine includes a third driving member, a second rotating shaft 61 and a flattening wheel 611 fixedly connected to the second rotating shaft 61, and the third driving member is connected to the second rotating shaft 61 in a transmission manner to drive the flattening wheel 611 to rotate tangentially to the pasting wheel 511. By providing the flattening wheel 611, the third driving member drives the second rotating shaft 61 to rotate, so as to drive the flattening wheel 611 fixedly connected to the second rotating shaft 61 to rotate tangentially to the pasting wheel 511, so as to flatten the tax stamp. The flattening wheel 611 can also be used to emboss the tax stamp with patterns or the like.

[0049] Alternatively, if Figure 1 As shown, multiple protrusions 5111 are evenly spaced on the outer circumference of the posting wheel 511, and multiple negative pressure ports for receiving tax bills are provided on each protrusion 5111, and the flattening wheel 611 can rotate tangent to the protrusions 5111. By evenly spaced multiple protrusions 5111 on the outer circumference of the posting wheel 511, and multiple negative pressure ports are provided on each protrusion 5111, it is convenient to suck the tax bills on the protrusions 5111 transferred from the suction nozzle 3 to the posting wheel 511, thereby preventing the tax bills from being separated from the posting wheel 511. When the flattening wheel 611 is tangent to the protrusions 5111 of the posting wheel 511, the flattening wheel 611 and the posting wheel 511 realize flattening of the tax bills, thereby facilitating the glue spraying machine 7 to spray glue on the tax bills.

[0050] Alternatively, if Figure 1 As shown, the tax invoice sticking machine includes a glue sprayer 7, which is used to spray glue on the tax invoice passing through the flattening wheel 611. By setting the glue sprayer 7, when the tax invoice is flattened by the flattening wheel 611, the glue sprayer 7 sprays glue on the tax invoice. After the glue spraying is completed, the posting wheel 511 drives the tax invoice to continue rotating, so as to attach the tax invoice to the object. Specifically, the glue sprayer 7 is fixedly arranged on the frame 10, and the tax invoice sticking machine also includes a belt rotatably arranged on the frame 10. When the glue sprayer 7 finishes spraying glue on the tax invoice, the pressure of the negative pressure port on the posting wheel 511 is converted into positive pressure, and the tax invoice is posted on the object. The belt drives the object with the tax invoice posted away from the posting wheel 511. It can be understood that the relative movement speed of the belt and the posting wheel 511 is the same or similar, so as to facilitate the posting of the tax invoice on the object.

[0051] Alternatively, if Figure 1 , Figure 2 and Figure 5-7As shown, the first driving member, the second driving member and the third driving member are the same driving motor 8, the tax stamp machine also includes a transmission mechanism, the transmission mechanism includes a transmission belt 91, a first pulley 92, a second pulley 93 and a third pulley 94, the tax stamp machine also includes an input shaft, the input shaft includes a third shaft and a fourth shaft connected to each other, the driving motor 8 is transmission-connected to the third shaft, the first pulley 92 is fixedly connected to the third shaft, the first planetary gear 221 is rotationally connected to the fourth shaft, the second pulley 93 is fixedly arranged on the first rotating shaft 51, and is spaced apart from the posting wheel 511 on the first rotating shaft 51, the third pulley 94 is fixedly arranged on the second rotating shaft 61, and is spaced apart from the flattening wheel 611 on the second rotating shaft 61, and the transmission belt 91 is sequentially wound around the first pulley 92, the second pulley 93 and the third pulley 94. By setting the first driving member, the second driving member and the third driving member as the same driving motor 8, the output shaft of the driving motor 8 is connected to the third shaft of the input shaft, the first pulley 92 is fixedly connected to the third shaft, the first planetary wheel 221 is rotatably connected to the fourth shaft, the second pulley 93 is fixedly connected to the first rotating shaft 51 and is spaced apart from the posting wheel 511 on the first rotating shaft 51, the third pulley 94 is fixedly connected to the second rotating shaft 61 and is spaced apart from the flattening wheel 611 on the second rotating shaft 61, when the driving motor 8 drives the first pulley 92 to rotate, the first pulley 92 is connected to the second pulley 93 and the third pulley 94 through the transmission belt 91 to drive the second pulley 93 and the third pulley 94 to rotate, thereby driving the first planetary wheel 221, the posting wheel 511 and the flattening wheel 611 to rotate, so as to realize taking the tax invoice from the ticket library 1 and posting the tax invoice on the object. Among them, the input shaft, the first rotating shaft 51 and the second rotating shaft 61 are all rotatably set on the frame 10 through bearings. In other embodiments, the first driving member, the second driving member, and the third driving member may also be three independently arranged motors.

[0052] Alternatively, if Figure 6 As shown, the transmission mechanism also includes a tensioning wheel 95, which is used to tension the transmission belt 91. By setting the tensioning wheel 95, the tensioning wheel 95 is used to adjust the tension of the conveyor belt to ensure that the transmission mechanism works effectively. Wherein, the tensioning wheel 95 is rotatably arranged on the frame 10.

[0053] Optionally, the gear ratio between the first internal gear 21 and the first planetary gear 221 and the gear ratio between the second gear 232 and the first gear 41 are both n:1, wherein the value range of n is 3-5.

[0054] In this embodiment, n=3, then the gear ratio of the first internal gear 21 to the first planetary gear 221 and the gear ratio of the second gear 232 to the first gear 41 are both 3:1. Figure 1-3 As shown, three planetary assemblies 22 are arranged in the first planetary gear system, three protrusions 5111 are evenly arranged on the outer circumference of the posting wheel 511, and three slots 231 are evenly spaced along the circumferential direction of the first planetary carrier 23.

[0055] like Figure 1-7 As shown, each planetary assembly 22 includes a first planetary gear 221, a roller 223 and a roller shaft 222. The driving motor 8 drives the first planetary gear 221 to rotate around the first internal gear 21. The roller shaft 222 is fixedly connected to the pitch circle of the first planetary gear 221. The roller 223 is rotatably connected to the roller shaft 222, so that the first planetary gear 221 drives the roller 223 to rotate in the slot 231 of the first planetary carrier 23. When the first planetary gear 221 rotates around the first planetary carrier 23, the roller 223 rotates around the first internal gear 21 along with the first planetary gear 221. While moving, it makes a linear motion along the slot 231, so that the first planetary gear 221 has a state of nearly stopping speed every time it rotates one circle. The first planetary carrier 23 is fixedly provided with a second gear 232, and the second planetary carrier 44 is fixedly provided with a first gear 41. The first gear 41 is engaged with the second gear 232 to drive the second gear 232 to rotate. The first gear 41 is fixedly provided on the first shaft 441 of the second planetary carrier 44, and the second planetary gear 42 is rotatably provided on the second shaft 442 to drive the second planetary gear 42 to rotate around the second internal gear 43, thereby driving the suction nozzle 3 to rotate.

[0056] The gear ratio of the first internal gear 21 to the first planetary gear 221 is 3:1, and the gear ratio of the second gear 232 to the first gear 41 is 3:1. Figure 1-5 As shown, when the first planetary gear 221 rotates around the first internal gear 21 once, the first planetary gear 221 rotates three times, and the first planetary gear 221 drives the roller 223 to rotate in the slot 231, so that the first planetary carrier 23 has three approximate stop states, thereby making the second gear 232 have three approximate stop states, the second gear 232 is engaged with the first gear 41, the first gear 41 is fixedly mounted on the first shaft 441 of the second planetary carrier 44, the second planetary gear 42 is rotatably mounted on the second shaft 442, and the suction nozzle 3 is fixedly connected to the second planetary gear 42, so that the suction nozzle 3 has three approximate stop states to absorb the tax invoice.

[0057] Among them, Figure 1-5 As shown, by fixing the roller shaft 222 on the pitch circle of the first planetary gear 221, the first planetary gear 221 drives the roller 223 to rotate around the first internal gear 21 and move linearly along the slot 231, so that the movement trajectory of the roller 223 is as shown in FIG. Figure 7 As shown, the motion law of the second planet carrier 44 is obtained as follows: Figure 8 and Fig. 9 ,like Figure 8 As shown, in each approximate rest state, the rotation angle of the second gear 232 is about 50°. At this time, the suction nozzle 3 is in an approximate rest state, so that the suction nozzle 3 can smoothly suck the tax bill from the bill bank 1; Fig. 9As shown, the acceleration of the second planetary carrier 44 changes continuously, so the second planetary carrier 44 does not have a sudden change in speed and acceleration, and the suction nozzle 3 does not have a sudden change in speed and acceleration during the process of sucking and transferring the tax invoice, wherein the first planetary gear train and the second planetary gear train make unidirectional rotational motion driven by the drive motor 8, so the gears of the first planetary gear train and the second planetary gear train are in single-sided contact during the transmission process, which can effectively reduce the wear and impact of the gears on the gears caused by the tooth side clearance at the gear meshing point, thereby ensuring the smooth operation of the suction nozzle 3.

[0058] By setting the gear ratio of the second internal gear 43 to the second planetary gear 42 to be 2:1, the first planetary gear 221 rotates once, driving the second planetary gear 42 to rotate once around the second internal gear 43, and the suction nozzle 3 completes one ticket suction and ticket sticking.

[0059] like Figure 1-7 As shown, by evenly arranging three protrusions 5111 on the outer circumference of the posting wheel 511, when the first planetary wheel 221 rotates around the first planetary frame 23, the first planetary wheel 221 rotates three times, driving the second planetary wheel 42 to rotate three times around the second planetary frame 44, and the suction nozzle 3 completes three times of sucking and pasting tickets. During the three ticket pasting processes, the tax bills are successively adsorbed on the negative pressure ports of the three protrusions 5111 of the posting wheel 511, and then the flattening wheel 611 rotates tangent to the protrusions 5111 on the posting wheel 511 to flatten the tax bills. After flattening, the glue sprayer 7 is used to spray glue on the flattened tax bills. Finally, the posting wheel 511 drives the glued tax bills to continue to rotate so that the tax bills are tangent to the objects, and the negative pressure ports on the protrusions 5111 are converted into positive pressure to post the tax bills on the objects. It can be understood that the rotation ratio of the first pulley 92, the second pulley 93 and the third pulley 94 is 3:1:3, so that when the posting wheel 511 rotates one circle, the rolling wheel 611 rotates three circles, completing three times of rolling. Among them, the negative pressure port of the posting wheel 511 and the pneumatic system that provides positive and negative pressure air sources for the suction nozzle 3, the oil supply system that provides lubricating oil for each gear, and other necessary auxiliary systems of the tax stamp machine do not belong to the core content of the present invention, so they are briefly described.
