DETAILED DESCRIPTION

[0040] The following will be combined with the attached Figure 1-10 , the technical solutions in the embodiments of the present invention are clearly and completely described. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0041] The inventor of this application found that with the rapid economic growth in recent years, the money supply has continued to increase, and banks are facing huge pressure on cash circulation. In order to solve this problem, a sealing and cutting device for banknote packaging came into being. To this end, this application mainly adopts the following methods to achieve accurate sealing and cutting of plastic sealing film and efficient and neat packaging of money bundles, ensuring that the hot sealing line of the plastic sealing film is located at the midline of the money bundle, so that the money bundle is not easy to fall apart when falling from a high altitude, and can adaptively level the cutter during the sealing and cutting process to ensure the sealing and cutting effect.

[0042] Reference Figure 1 and Figure 2The banknote film wrapping and sealing device provided in the embodiment of the present application includes a box body 10 and a film separation assembly 20, a coin support assembly 30, a film wrapping and sealing mechanism and a transmission assembly 70 installed in the box body 10, wherein the film wrapping and sealing mechanism includes a cutter assembly 40, a sealing and cutting support assembly 50 and a driving assembly 60, which achieves the sealing and cutting of a plastic film (not shown in the figure) and ensures that the hot sealing line of the plastic film is located at the midline of the money bundle, thereby improving the appearance quality and practicality of the sealing and cutting.

[0043] Reference Figure 1 and Figure 3 Specifically, the film separation assembly 20 includes a film separation plate 21. In this embodiment, the film separation plate 21 is arranged in a V-shaped plate, and a first flap 22 and a second flap 23 are hinged on the upper and lower sides away from the feed end, respectively. The plastic film 100 is sleeved on the outer sides of the film separation plate 21, the first flap 22 and the second flap 23 to form a U-shaped film. The side of the U-shaped film away from the feed end is a hot-sealed closed end 102, so that the plastic film 100 has only two sides with open ends 101. When sealing and cutting the plastic film 100, the open ends 101 only need to be sealed.

[0044] Among them, a banknote entrance 210 is provided on one side of the film separation plate 21 corresponding to the open end 101, so that the banknote 200 can enter the inner side of the film separation assembly 20. An entrance coin pusher assembly 24 is provided at the banknote entrance 210, and the entrance coin pusher assembly 24 includes a push rod and a push rod driving assembly for driving the push rod to move. One side of the film separation plate 21 extends out of the outer side of the film separation plate 21, and the push rod is slidably connected with the film separation plate 21. The banknote 200 can be placed on the top surface of the film separation plate 21, and the banknote 200 is pushed to the inner side of the film separation plate 21 by the push rod. In this embodiment, the push rod driving assembly 60 is a gear rack mechanism.

[0045] Reference Figure 2 and Figure 3 After the banknote 200 is pushed to the inner side of the film separation plate 21, it is necessary to transfer the banknote 200 to the coin support assembly 30. Therefore, a sealing and cutting coin pusher assembly 25 is provided on the inner side of the film separation plate 21. The sealing and cutting coin pusher assembly 25 can also be a scheme of a gear rack mechanism combined with a pusher plate. When the banknote 200 enters the inner side of the film separation plate 21, the sealing and cutting coin pusher assembly 25 is used to push it to the coin support assembly 30. During the pushing process, the banknote 200 abuts against the inner side of the hot-sealed closed end 102 of the plastic film 100 to pull the plastic film 100 to the position of the coin support assembly 30.

[0046] Reference Figure 2The coin holding assembly 30 is arranged at the discharge end of the film separation assembly 20. In this embodiment, the coin holding assembly 30 includes a coin holding base 31, a coin holding conveyor belt 32 and a coin holding lifting mechanism. The coin holding conveyor belt 32 is arranged on the coin holding base 31, and the banknotes 200 can be conveyed to the coin holding conveyor belt 32. The coin holding lifting mechanism is arranged below the coin holding base 31, and is used to drive the coin holding conveyor belt 32 to rise and fall. The coin holding lifting mechanism can be a screw lifting mechanism or a cylinder driving mechanism. After the sealing and cutting is completed, the banknotes 200 can be quickly transferred out through the coin holding assembly 30.

[0047] Reference Figure 4 and Figure 5 The cutter assembly 40 mainly includes a cutter support 41, a cutter base 42, a cutter 43 and a protective cover 44. Figure 4 and Figure 6 The sealing and cutting support assembly 50 includes a sealing and cutting bracket 51 , a sealing and cutting base 52 , a heat insulation plate 53 , a sealing and cutting adaptive guide shaft 54 ​​and a sealing and cutting adaptive elastic member 55 .

[0048] Reference Figure 4 The cutter bracket 41 and the sealing and cutting bracket 51 are offset up and down and are slidably connected through a guide rod. The driving assembly 60 is a bidirectional screw assembly. The output end of the bidirectional screw assembly is connected to the middle of the cutter bracket 41 and the sealing and cutting bracket 51, so that the center of gravity of the cutter bracket 41 and the sealing and cutting bracket 51 coincides with the center of gravity of the bidirectional screw assembly as much as possible, avoiding the increase of the radial force of the screw due to the misalignment of the center of gravity, thereby accelerating the wear of the screw nut.

[0049] In a preferred embodiment, the bidirectional screw assembly includes a trapezoidal screw, and a thrust ball bearing is provided between the trapezoidal screw and the cutter bracket 41 and the sealing and cutting bracket 51 to effectively bear the gravity load. In addition, the lead angle of the trapezoidal screw thread needs to be specially designed to achieve the self-locking function between the trapezoidal screw and the cutter bracket 41 and the sealing and cutting bracket 51, and to ensure the stability of the cutter bracket 41 and the sealing and cutting bracket 51 after relative movement.

[0050] Reference Figure 4The cutter base 42 is fixed to the top of the cutter bracket 41, the cutter base 42 is frame-shaped, and the cutter 43 is installed on the bottom side of the cutter base 42; the sealing and cutting base 52 is installed on the top of the sealing and cutting bracket 51, the sealing and cutting adaptive guide shaft 54 ​​is fixed on the sealing and cutting base 52, the sealing and cutting adaptive guide shaft 54 ​​slides through the insulation board 53, and the sealing and cutting adaptive elastic member 55 is arranged between the insulation board 53 and the sealing and cutting base 52. Optionally, the sealing and cutting adaptive elastic member 55 is a telescopic spring. The cutter assembly 40 and the sealing and cutting support assembly 50 can be close to each other, and the abutment between the cutter 43 and the insulation board 53 enables the cutter 43 to be in parallel contact with the insulation board 53 and seal and cut it. The insulation board 53 is automatically leveled by the sealing and cutting adaptive elastic member 55, so that the cutter 43 can fully contact with the insulation board 53 during the sealing and cutting process, ensuring that the plastic film 100 is completely burned off and sealed, eliminating the parallelism requirement of the cutter 43 and the insulation board 53, reducing the assembly accuracy requirement, and thus reducing costs.

[0051] Reference Figure 4 and Figure 7 Specifically, the cutter 43 includes a heating portion 431 and a blade 432 fixed to the heating portion 431. A heating groove 433 is provided in the heating portion 431, and the heating groove 433 extends along the length direction of the cutter 43. A heating wire (not shown in the figure) is provided in the heating groove 433. A thermometer 434 is provided inside the heating portion 431, and the thermometer 434 is electrically connected to the heating wire. The heating wire in the heating portion 431 can evenly heat the blade 432 to ensure that the plastic film 100 is fully ironed during sealing and cutting. At the same time, the thermometer 434 is electrically connected to the heating wire to form a closed-loop control system to ensure that the temperature of the cutter 43 is constant, and to avoid the problem of poor ironing of the plastic film 100 due to temperature fluctuations during the sealing and cutting process.

[0052] Preferably, the heating wire is made of nickel-chromium alloy, which is widely used in resistance wires and heating elements because of its advantages of high resistivity, thermal fatigue resistance, oxidation resistance and high temperature stability. The temperature detector 434 is a K-type thermocouple. The angle of the blade 432 is 90°, which can prevent the hot-sealing line from being too thin and easy to crack, and can also prevent the wire drawing phenomenon after cutting the film, which affects the sealing effect.

[0053] Among them, a heat-conducting insulating sheet (not shown in the figure) is arranged between the heating groove 433 and the heating wire. The heat-conducting insulating sheet can be a mica sheet. The mica sheet has good thermal conductivity and insulation, ensuring good thermal conductivity and no electricity on the blade 432. In addition, a polytetrafluoroethylene adapter plate is arranged between the cutter 43 and the cutter base 42, so as to better isolate the heat of the cutter 43 and avoid temperature loss.

[0054] Reference Figure 4, the protective cover 44 is arranged on the peripheral side of the cutter 43 to further isolate the heat loss. In this embodiment, a protective guide shaft 441 is fixed on the cutter base 42, the protective cover 44 is slidably connected to the protective guide shaft 441, a protective reset elastic member 442 is sleeved on the outer periphery of the protective guide shaft 441, and the protective reset elastic member 442 can be a telescopic spring. The protective cover 44 is slidably connected to the cutter base 42 through the protective reset elastic member 442 and the protective guide shaft 441, and a cutter hole 443 for the cutter 43 to move in or out is opened on the bottom side of the protective cover 44, and the outer wall of the protective cover 44 can abut against the heat insulation board 53.

[0055] Under the action of the protective reset elastic member 442, the cutter 43 is normally located in the protective cover 44. When the cutter 43 and the heat insulation board 53 are close to each other, the protective cover 44 first abuts against the heat insulation board 53, and then the protective cover 44 moves up, and the cutter 43 abuts against the heat insulation board 53 to achieve sealing and cutting of the plastic film 100. The design of the outer wall of the protective cover 44 abutting against the heat insulation board 53 can ensure that the cutter 43 is in full contact with the heat insulation board 53, thereby improving the stability and sealing quality during the sealing and cutting process.

[0056] Reference Figure 8 Preferably, the bottom side of the protective cover 44 is provided with an exhaust nail 45, and the exhaust nail 45 is arranged along the length direction of the cutter 43. The exhaust nail 45 can pierce the plastic film 100 during the sealing and cutting process, so as to discharge the air in the film during the sealing and cutting process, ensure that there are no bubbles in the plastic film 100 after sealing and cutting, and improve the sealing and cutting quality of the plastic film 100. At the same time, the design of the exhaust nail 45 can avoid the problem of poor sealing and cutting caused by the accumulation of air in the film.

[0057] Reference Fig. 9 and Fig.10 The transmission assembly 70 includes a shift shaft 71 and a shift plate 72, which are used to connect the movement between the cutter assembly 40 and the first flap 22, and the sealing and cutting support assembly 50 and the second flap 23.

[0058] In this embodiment, the shift shaft 71 is fixed to the side of the cutter base 42, the shift shaft 71 is located above the first flap 22, the shift plate 72 is installed on the side of the heat insulation plate 53, and the shift plate 72 is located below the second flap 23. The first flap 22 is connected to the side of the transmission plate 73, and the transmission plate 73 is provided with a shift hole 731. The shift hole 731 can be designed as a rectangular hole. The size of the shift hole 731 is larger than the size of the shift shaft 71. The shift shaft 71 passes through the shift hole 731 and can move freely in the shift hole 731 to push the first flap 22 to rotate. The top side of the shift plate 72 is in sliding contact with the bottom side of the second flap 23, so that the sealing and cutting support assembly 50 can directly push the second flap 23 to flip when it moves.

[0059] Reference Fig.10When the cutter assembly 40 and the sealing and cutting support assembly 50 are close to each other, the first flap 22 and the second flap 23 are driven to be close to each other, so that the open end 101 of the U-shaped film is in a state more conducive to sealing and cutting, and the quality of the hot-sealing line after sealing and cutting is improved. The present application solution can quickly adjust the hot-sealing line position by adjusting the position of the coin support assembly 30 and the sealing and cutting position of the cutter assembly 40 and the sealing and cutting support assembly 50, which is convenient to adjust and has high sealing and cutting efficiency.

[0060] The implementation principle of this embodiment is: by accurately controlling the motion relationship between the film separation component 20, the coin support component 30, the film wrapping sealing and cutting mechanism and the transmission component 70, the plastic film 100 is accurately sealed and cut and the money bundles are efficiently and neatly packed. The device not only improves the sealing and cutting efficiency and reliability, but also provides good conditions for subsequent heat shrink exhaust through the design of the adaptive anti-scalding protection plate and the exhaust nail 45, ensuring that the final product has a beautiful appearance and stable quality. Compared with the prior art, the present invention optimizes the functionality and user experience of the overall equipment by integrating multiple structural innovations, and is suitable for widespread promotion and use in the banking and financial industries.
