[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1 As shown, the present invention proposes a pressing structure for a banknote lamination packaging machine, including: a banknote feeding platform 1, a banknote pressing component disposed above the banknote feeding platform 1, four sorting components disposed on both sides of the banknote feeding platform 1, and a control unit for controlling the pressing component and the four sorting components to perform pressing and sorting actions.

[0033] Among them, such as Figure 2 As shown, the banknote pressing component includes a pressing rod 3 located above the banknote dispensing platform 1, and an adjusting part 2 disposed at one axial end of the pressing rod 3, which can drive the pressing rod 3 to move up and down along the length direction parallel to the banknote dispensing platform 1. The adjusting part 2 includes a threaded rod 6 that is perpendicular to the axial direction of the pressing rod 3 and horizontally arranged, a mounting bracket 7 for supporting the threaded rod 6, and a first cylinder 8 disposed below the mounting bracket 7. The axial direction of the pressing rod 3 is parallel to the top surface of the banknote dispensing platform 1, and two pressing rods 3 can be provided, which are symmetrically arranged.

[0034] Among them, such as Figure 2As shown, the outer circumferential side of the threaded rod 6 on both axial sides is respectively provided with threads in opposite directions, the threaded rod 6 passes through the end of the corresponding end of the two banknote pressing rods 3 in turn, the corresponding ends of the two banknote pressing rods 3 are respectively threadedly connected with the threads on both sides of the threaded rod 6, and the two ends of the threaded rod 6 are respectively rotatably connected with the mounting frame 7; the bottom of the mounting frame 7 is fixedly connected with the output end of the first air cylinder 8, the first air cylinder 8 can be fixed on the banknote placing platform 1, the mounting frame 7 is driven to move up and down by the first air cylinder 8, and then the mounting frame 7 drives the threaded rod 6 and the banknote pressing rod 3 to move up and down, so as to realize the pressing and loosening of the banknote bundle 21. One end of the mounting frame 7 is fixedly provided with a stepping motor 9, and the motor shaft of the stepping motor 9 is fixedly connected with the corresponding end of the threaded rod 6 in the axial direction; for paper currency of different denominations, the distance between the two banknote pressing rods 3 can be adjusted according to the size of the paper currency, so that the banknote pressing rod 3 is pressed on the appropriate position of the banknote bundle 21. The two banknote pressing rods 3 have a distance therebetween, which is mainly used to wrap the pre-wrapping film 23 at the position after the paper currency is pressed, as shown in Figure 1 As shown, the pre-wrapping film 23 is pre-wrapped by the pre-wrapping mechanism in the prior art.

[0035] In addition, as shown in Figure 3 The side plate 10 is fixedly provided on the side of the banknote placing platform 1 close to the adjusting part, and a plurality of groups of limiting grooves 11 for placing the banknote pressing rods 3 are arranged at the upper part of the side plate 10 in a spaced manner. Each group of limiting grooves 11 is composed of two symmetrically arranged limiting grooves 11, and the two limiting grooves 11 in the same group are symmetrically arranged on both sides of the length direction of the side plate 10 and about the median line of the long side of the side plate 10. That is, the plurality of groups of limiting grooves 11 are arranged from the center of the side plate 10 to both sides in turn. The end of the banknote pressing rod 3 away from the threaded rod 6 passes through the corresponding limiting groove 11 and is slidably connected with the limiting groove 11, and the limiting groove 11 is mainly used to limit the position of the banknote pressing rod 3. The two ends of the mounting frame 7 are respectively slidably connected with the corresponding two ends of the side plate 10. Each group of limiting grooves 11 corresponds to paper currency of different denominations, and the distance between each group of limiting grooves 11 and the distance between adjacent two groups of limiting grooves 11 are designed according to the area or length of different paper currency in advance. For paper currency with smaller area or shorter length, the banknote pressing rod 3 can be located in the middle group of A and B limiting grooves 11; for paper currency with longer length, the banknote pressing rod 3 can be located in the C and D limiting grooves 11 which are only next to the outside of the A and B limiting grooves 11, or in the E and F limiting grooves 11 which are only next to the outside of the C and D limiting grooves 11; the specific number or distance of the limiting grooves 11 can be set according to the actual situation.

[0036] When different denominations of paper currency are replaced, the horizontal distance between the two banknote pressing rods 3 needs to be adjusted, and the mounting frame 7 is moved to above the top of the side plate 10, as shown in Figure 2As shown, at this time, the banknote pressing rods 3 are separated from the limiting grooves 11, and the threaded rods 6 can be driven to rotate by the stepping motor 9, so that the two banknote pressing rods 3 on the threaded rods 6 move in opposite directions, thereby adjusting the distance between the two banknote pressing rods 3.

[0037] As shown in Figure 1 , Figure 2 , Figure 8 and Figure 9 , the arranging and aligning component includes the arranging and aligning parts 4 symmetrically and slidingly arranged on both sides of the banknote placing platform 1, and a driving part arranged below the banknote placing platform 1 and driving the two arranging and aligning parts 4 to simultaneously move towards or away from the center of the banknote placing platform 1. The banknote pressing rods 3 are located in the middle of the two arranging and aligning parts 4.

[0038] Specifically, the arranging and aligning part 4 includes a sliding frame 12 arranged in parallel with the banknote pressing rods 3, and L-shaped frames 13 symmetrically arranged at both ends of the sliding frame 12. As shown in Figure 5 , Figure 6 , the L-shaped frame 13 is in the form of an L-shaped plate. As shown in Figure 4 and 5 in combination with Figure 6 , the bending part of the L-shaped frame 13 is a right angle, and the lengths of the two right-angle sides of the L-shaped frame 13 are equal. The bending part of the L-shaped frame 13 is rotationally connected to the sliding frame 12 through a connecting pin 25 arranged on the upper part thereof, and the free ends of the two right-angle sides of the L-shaped frame 13 are rotationally provided with aligning rods 14 perpendicular to the banknote placing platform 1, and the bottom of the aligning rod 14 is in contact with the surface of the banknote placing platform 1. In addition, as shown in Figure 4-7 , the top of the L-shaped frame 13 is further provided with an elastic mechanism for driving it to reset, which can be a spring 15. One end of the spring 15 can be fixed to a position (N position in Figure 6 ) on the outer side of the sliding frame 12 through a fixing column 24, and the other end can be fixed to a position (M position in Figure 6 ) on the inner side of the L-shaped frame 13 through a fixing column 24.

[0039] As shown in Figure 8 , Figure 9 , the driving part includes a rotating plate 16, rotating rods 17 rotationally arranged at both ends of the rotating plate 16, and a second air cylinder 18 arranged on the outer side of one of the sliding frames 12. The rotating plate 16 is arranged below the banknote placing platform 1 and located at the center of the two sliding frames 12, i.e., the rotating plate 16 is located at the center of the distance between the two sliding frames 12. The bottom of the banknote placing platform 1 is fixedly provided with a bottom plate 26, and the center of the rotating plate 16 is rotationally connected to the bottom plate 26 fixedly arranged on the bottom of the banknote placing platform 1. The ends of the two rotating rods 17 away from the rotating plate 16 are respectively rotationally connected to the sliding frames 12 on both sides through rotating shafts 19, and the output end of the second air cylinder 18 is fixedly connected to one of the sliding frames 12 on the corresponding side. As shown in Figure 2 , Figure 3 and Figure 4As shown, in the present embodiment, the rotation shaft 19 is perpendicular to the top surface of the banknote depositing platform 1, the number of the rotation shaft 19 is two, and the rotation shaft 19 is arranged at the center of the bottom of the sliding frame 12. The banknote depositing platform 1 is symmetrically provided with a long slot 20 penetrating the banknote depositing platform 1 at both sides of the banknote depositing platform 1, the long slot 20 is a through slot, and the lower end of the rotation shaft 19 of the two sliding frames 12 penetrates the corresponding long slot 20 and is rotationally connected with the end of the rotation rod 17 away from the rotation plate 16. In addition, the banknote depositing platform 1 is symmetrically provided with a sliding slot 22 at both sides, and each side of the sliding slot 22 is symmetrically provided with two sliding slots, and each sliding slot 22 is slidingly connected with the two ends of the corresponding sliding frame 12.

[0040] The specific working mode of the aligning component in the present embodiment is described as follows: first, as shown in Figure 6 , the piston rod end of the second cylinder 18 pushes one of the sliding frames 12, so that the sliding frame 12 moves to the center of the banknote depositing platform 1. When the sliding frame 12 moves to the center, the rotation rod 17 connected with the sliding frame 12 rotates, the rotation plate 16 rotates the other rotation rod 17, and the other rotation rod 17 drives the other sliding frame 12 to move to the center synchronously with the sliding frame 12. Thus, the two sliding frames 12 move to the center of the banknote depositing platform 1 synchronously, and the four L-shaped frames 13 on the two sliding frames 12 are located at the four corners of the banknote bundle 21. During the movement, the aligning rods 14 gradually approach the banknote bundle 21. After the aligning rods 14 contact the banknote bundle 21, the banknote bundle 21 is pushed to the center of the banknote depositing platform 1, and during the movement, the eight aligning rods 14 gradually contact the side walls of the banknote bundle 21 and gradually align the position of the banknote bundle 21.

[0041] The initial state of the two aligning rods 14 on each L-shaped frame 13 is as shown in Figure 6 . The L-shaped frames 13 on the two sliding frames 12 are symmetrical, that is, the right angles of the L-shaped frames 13 are both directed to the Figure 6 . This is because the spring 15 is arranged. One end of the spring 15 is fixed on the L-shaped frame 13 and at the inner side of the L-shaped frame 13 (the M position in Figure 6 ), and the other end of the spring 15 is fixed at the outer side of the sliding frame 12 (the N position in Figure 6 ). During the movement, the aligning rod 14 at the M position can first contact the banknote bundle 21 and then push the banknote bundle 21 inward. When the banknote bundle 21 gradually moves to the center of the banknote depositing platform 1, the two sides of the banknote bundle 21 are limited, at this time, the four L-shaped frames 13 interact with each other. During the pushing process, the aligning rod 14 at the M position exerts a force on the L-shaped frame 13, so that the L-shaped frame 13 rotates in the direction of the curved arrow in Figure 6 , and the spring 15 is stretched, so that the other aligning rod 14 of the same group contacts the other adjacent side wall of the banknote bundle 21. Thus, the two aligning rods 14 of the same group contact the adjacent two side walls of the banknote bundle 21, and the four groups of aligning rods 14 contact the corresponding side walls of the banknote bundle 21, so as to align the banknote bundle 21, as shown inFigure 7 as shown.

[0042] The control part is electrically connected with the driving part and the adjusting part 2, wherein the first cylinder 8, the second cylinder 18 and the stepping motor 9 are electrically connected with the control part, and the control part controls the opening and closing of the first cylinder 8, the second cylinder 18 and the stepping motor 9. The control part is controlled by programming, and the control mode does not belong to the protection scope of the present application, and is not described in detail here.

[0043] In the application, when the banknote bundle 21 is placed on the banknote placing platform 1, the control part controls the second cylinder 18 to open, the sliding frame 12 is moved by the second cylinder 18, the banknote bundle 21 is pushed to the center position of the banknote placing platform 1 by the arranging part 4, and the banknote bundle 21 is adjusted. Then, the control part adjusts the distance between the two banknote pressing rods 3 according to the area of the banknote, the stepping motor 9 is controlled to start, the threaded rod 6 is rotated, the distance between the two banknote pressing rods 3 is adjusted, and the banknote pressing rod 3 is located above the corresponding limiting groove 11. Then, the control part controls the first cylinder 8 to open, the mounting frame 7 is moved downward, the banknote pressing rod 3 is moved downward along the limiting groove 11, and the two ends of the banknote bundle 21 are pressed. Finally, the banknote bundle 21 is pre-wrapped by the film wrapping mechanism. The film wrapping mechanism is prior art, and is not described in detail here.

[0044] The arranging part is arranged in the application, the banknote bundle 21 can be moved to the center of the banknote placing platform 1 and adjusted before pre-wrapping. Then, the banknote bundle 21 is pressed by the banknote pressing part, so that the banknote bundle 21 is not damaged or the film is not damaged due to the improper position of the banknote bundle 21. The distance between the two pressing rods in the banknote pressing part can be adjusted according to different denominations of banknotes, and the banknotes of different sizes can be pressed in the most appropriate position.
