Description

Technical Field

[0001] This utility model belongs to the field of financial equipment technology, specifically a banknote bundling machine. Background Technology

[0002] In existing banknote bundling machines, the internal heating head typically employs a fast-heating soldering iron structure. This structure uses a nickel-chromium alloy within the heating head that is electrically heated. The control principle involves adjusting the heating element's temperature by controlling the energizing time or current. The temperature rises rapidly over a short period, and if the temperature is insufficient, the bond may be weak. Conversely, if the temperature exceeds the material's bonding temperature, it can lead to over-melting. Utility Model Content

[0051] The following is in conjunction with the appendix Figure 1-20 The present invention will be described in further detail.

[0052] A type of banknote bundling machine, such as Figure 1-20 As shown, this embodiment includes a base plate 001, a pressing structure, a hot-stick cutting structure, and a guide structure. The pressing structure is mounted on the base plate 001, and the hot-stick cutting structure and guide structure are respectively connected to the pressing structure. The hot-stick cutting structure includes an upper heating head 1, a first pressing foot 002, a rear pressing foot 003, a cutter 004, and a hot-stick cutting drive mechanism 005 for driving the upper heating head 1, the first pressing foot 002, the rear pressing foot 003, and the cutter 004. The overall structure of the hot-stick cutting drive mechanism 005 itself, and the connection structure between the hot-stick cutting drive mechanism 005 and the upper heating head 1, the first pressing foot 002, the rear pressing foot 003, and the cutter 004, all adopt existing technologies. The overall structure of the hot-stick cutting drive mechanism 005 itself can adopt existing methods including a horizontal binding assembly for the cutter holder, a vertical binding assembly for the cutter holder, a tension spring fixing bracket, a motor, a camshaft fixing bracket, a horizontal binding cam group, a vertical binding cam group, a gear group, and tension springs. In this embodiment, the hot-sticking and cutting drive mechanism 005 drives the entire assembly consisting of three sets of hot-sticking heads 1, a first presser foot 002, a rear presser foot 003, and a cutter 004 to process the three points of the binding strap located above the banknote stack 006. The first presser foot 002 and the rear presser foot 003 are used to press down on the corresponding binding straps, the hot-sticking head 1 hot-sticks the corresponding positions, and then the cutter 004 cuts the completed binding strap.

[0053] In this embodiment, the heating head 1 includes a heating head base 101, a heating element 102, a temperature sensor 103, and a ceramic heating element 104. The upper end of the heating head base 101 is connected to the heating and adhesive tape cutting drive mechanism 005. A through-hole for the heating element is formed inside the heating head base 101. The heating element 102 is embedded in the lower opening of the heating element mounting hole, and its upper part extends into the heating element mounting hole. The temperature sensor 103 and the ceramic heating element 104 are respectively embedded from the upper part of the heating element 102. Both the temperature sensor 103 and the ceramic heating element 104 are commercially available products and are connected to the controller of the banknote binding machine via wires. The heating element mounting hole is also used for passage. In this embodiment, the heating element 102 is an integral component made of copper, which has good thermal conductivity. The fixed connection between it and the heating head base 101 also adopts existing technology. The upper heating head 1, with its structure of temperature sensor 103 and ceramic heating element 104, features a relatively slow initial heating speed of ceramic heating element 104. Temperature sensor 103 can monitor the temperature of heating element 102 in real time and communicate with the controller of the banknote bundling machine to achieve controllable closed-loop temperature control, ensuring that heating element 102 is always in the most suitable temperature range for bonding and effectively improving the bonding effect.

[0054] Specifically, such as Figure 1-4 As shown, the clamping structure in this embodiment includes a lower fixed plate 2, an upper fixed plate 3, a clamping drive component 4, and an upward coin-pushing plate 5. The lower fixed plate 2 is mounted on the base plate 001 via several support columns A 6, and the upper fixed plate 3 is mounted on the lower fixed plate 2 via several support columns B 7. Two lead screws 8 are rotatably mounted between the lower fixed plate 2 and the upper fixed plate 3. The upward coin-pushing plate 5 is located between the lower fixed plate 2 and the upper fixed plate 3. Nuts are provided on the upward coin-pushing plate 5 at positions corresponding to each lead screw 8. Each lead screw 8 is threadedly connected to its corresponding nut. The lower end of each lead screw 8 extends to the lower side of the lower fixed plate 2. The housing of the clamping drive component 4 is mounted on the lower fixed plate 2, and the drive end of the clamping drive component 4 is connected to the lower end of each lead screw 8 via a synchronous belt assembly 9. In this embodiment, the clamping drive component 4 uses a prior art motor reducer assembly, and its operation is controlled by the controller of the banknote bundling machine. The synchronous belt assembly 9 is configured in a prior art manner. The control clamping drive 4 moves, thereby driving the upward pushing coin plate 5 to rise and fall, so that the banknote stack 006 on the upward pushing coin plate 5 is clamped and fixed by the upward pushing coin plate 5 and the upper fixing plate 3 for subsequent bundling.

[0055] Specifically, the banknote bundling machine in this embodiment also includes an outer casing and a security door structure. The outer casing is mounted on the base plate 001 and is used to cover the internal structure of the entire machine. A banknote inlet / outlet is provided on the side of the outer casing near the upward-pushing coin plate 5. Figure 7As shown, the security door structure includes a door panel 10 and a door panel translation drive assembly 11, which is mounted on the lower fixed plate 2. The door panel translation drive assembly 11 drives the door panel 10 to move horizontally, opening or closing the banknote inlet / outlet of the outer shell. In this embodiment, the door panel translation drive assembly 11 is also configured using existing technology, for example, a structure composed of a motor reducer assembly, a synchronous belt, a guide rod, and a guide sleeve. After the door panel 10 is opened, the bundled banknote stack 006 is placed on the upward pushing banknote plate 5. Then the door panel 10 closes, and the pressing drive component 4 presses the banknote stack 006. After the bundling is completed, the pressing structure reverses its action, and the bundled banknote stack 006 can be removed after the door panel 10 is opened.

[0056] Specifically, such as Figure 8-20As shown, in this embodiment, the hot-stick cutting structure is mounted on the upper fixed plate 3, and one longitudinal feed and take-up assembly 12 and two transverse feed and take-up assemblies 13 are respectively installed on the upper fixed plate 3. In this embodiment, the specific structure of the longitudinal feed and take-up assembly 12 and the two transverse feed and take-up assemblies 13 are both in the form of existing technology consisting of a motor, a pressure wheel, and a feed and take-up assembly housing, etc., and are used for the release and rewinding of the strapping tape; the longitudinal feed and take-up assembly 12 and the two transverse feed and take-up assemblies 13 are respectively controlled by the controller of the banknote bundling machine. A guide groove A14 is installed on the lower side of the longitudinal feed and take-up assembly 12, and a guide groove B15 is installed on the lower side of each transverse feed and take-up assembly 13. The guide groove A14 is located on one side of the upward push coin plate 5 in the width direction. A guide groove C16 is provided on the lower side of the upper fixed plate 3 at the corresponding position of the guide groove A14. The guide groove C16 is located on the other side of the upward push coin plate 5 in the width direction. The two transverse feed and take-up assemblies 13 and the two guide grooves B15 are all located on the side of the upward push coin plate 5 away from the door plate 10. The door plate 10 is provided with a guide groove D17 that works in conjunction with the two guide grooves B15. The lower surface of the upper fixed plate 3 has a longitudinal conveyor channel A 301 and two transverse conveyor channels A 302. The upper surface of the upward-pushing coin plate 5 has a longitudinal conveyor channel B 501 and two transverse conveyor channels B 502. The longitudinal conveyor channel A 301 intersects with the two transverse conveyor channels A 302, and the longitudinal conveyor channel B 501 intersects with the two transverse conveyor channels B 502. Guide grooves are respectively formed on the guide grooves A14, C16, B15, and D17, which together form the guide structure of the banknote bundling machine. The specific design forms of the longitudinal conveyor channel A 301 and the two transverse conveyor channels A 302, as well as the design forms of the guide grooves, all adopt existing technologies. After the door panel 10 is closed and the banknote stack 006 is pressed, the binding straps are released longitudinally and laterally. The binding strap reel of the banknote binding machine can be installed on the outside of the lower fixed plate 2 and the upper fixed plate 3 through the bracket, and the installation method adopts existing technology.

[0057] The strapping tape output from the longitudinal feed and take-up assembly 12 first passes through the longitudinal conveyor channel A 301, then sequentially passes through the guide groove on the guide trough C16, the longitudinal conveyor channel B 501 on the upward pushing coin plate 5, and the guide groove on the guide trough A 14, before returning to the longitudinal conveyor channel A 301. The portion of the strapping tape that returns to the longitudinal conveyor channel A 301 is located below the portion of the strapping tape that first enters the longitudinal conveyor channel A 301.

[0058] The strapping tape output from each lateral feed assembly 13 first passes through the corresponding lateral feed channel A 302, then sequentially passes through the guide groove on the corresponding guide slot D 17, the corresponding lateral feed channel B 502 on the upward-pushing coin plate 5, and the guide groove on the corresponding guide slot B 15, before returning to the corresponding lateral feed channel A 302. The portion of the strapping tape returning to the lateral feed channel A 302 is located below the portion of the strapping tape that first enters the lateral feed channel A 302. The guide slot D 17 of the door panel 10 cannot allow the strapping tape to pass through when the door panel 10 is open.

[0059] like Figure 15-18 As shown, in this embodiment, the guide belt grooves A14, B15, C16, and D17 are all equipped with retractable spring baffle assemblies A18 for temporarily blocking the strapping tape in the guide belt grooves. The upward-pushing coin plate 5 is equipped with retractable spring baffle assemblies B19 for temporarily blocking the strapping tape in the longitudinal conveyor channel B501 and the two transverse conveyor channels B502.

[0060] A fixed partition plate A 20 is provided near the longitudinal feed and take-up assembly 12 in the longitudinal feed and take-up channel A 301 of the upper fixed plate 3 by screws. The fixed partition plate A 20 is used to separate the part of the strapping that is put back into the longitudinal feed and take-up channel A 301 from the part of the strapping that is put into the longitudinal feed and take-up channel A 301 for the first time.

[0061] A retractable spring baffle assembly C 21 is provided in the longitudinal conveyor channel A 301 of the upper fixed plate 3 at a distance away from the longitudinal feed and take-up assembly 12. The retractable spring baffle assembly C 21 is used to temporarily separate the portion of the strapping that is re-entered into the longitudinal conveyor channel A 301 from the portion of the strapping that is subsequently inserted into the longitudinal conveyor channel A 301 for the first time.

[0062] In each transverse conveyor channel A 302 of the upper fixed plate 3, a retractable spring baffle assembly D 22 is provided at a distance away from the corresponding transverse infeed assembly 13. The retractable spring baffle assembly D 22 is used to temporarily separate the portion of the strapping that is re-entered into the transverse conveyor channel A 302 from the portion of the strapping that is subsequently first inserted into the transverse conveyor channel A 302.

[0063] In each transverse conveyor channel A 302 of the upper fixed plate 3, near the corresponding transverse infeed assembly 13, there is a fixed partition plate B 23 and a retractable spring baffle assembly E 24. The fixed partition plate B 23 is located on the upper side of the retractable spring baffle assembly E 24. The fixed partition plate B 23 is used to separate the part of the strapping that returns to the transverse conveyor channel A 302 from the part of the strapping that enters the transverse conveyor channel A 302 for the first time. The retractable spring baffle assembly E 24 is used to temporarily block the part of the strapping that returns to the transverse conveyor channel A 302.

[0064] In this embodiment, the retractable spring baffle assemblies A18, B19, C21, D22, and E24 are arranged in basically the same or similar ways, and as follows: Figure 18 As shown, spring mounting slots are respectively opened on one or both sides of the conveyor channel or guide groove on the corresponding parts. A spring 34 and one end of a baffle 35 with an L-shaped axial cross-section are installed in the spring mounting slot. The spring mounting slot is covered by a pressure plate 36, and the other end of the baffle 35 extends to the inner side of the corresponding conveyor channel or guide groove. Normally, the other end of the baffle 35 remains extended under the elastic force of the spring 34 to block the strapping. When the strapping is tightened, the strapping exerts a pushing force on the baffle 35, causing the baffle 35 to retract into the spring mounting slot, thereby allowing the strapping to disengage from the conveyor channel or guide groove.

[0065] like Figure 10 , Figure 12 , Figure 19 and Figure 20 As shown, in this embodiment, the upper fixed plate 3 is also provided with a movable guide pad structure. The movable guide pad structure includes a guide block pad integral part 25, a gear and rack transmission assembly, and a gear and rack drive part 26. The gear and rack drive part 26 adopts a motor reducer assembly of existing technology and is controlled by the controller of the banknote bundling machine. The housing of the gear and rack drive part 26 is mounted on the upper fixed plate 3 through the gear and rack drive part mounting bracket 37. There are three guide block pad integral parts 25. One guide block pad integral part 25 corresponds to the passage of the hot-sticking and cutting strip structure in the longitudinal conveyor channel A 301, and the other two guide block pad integral parts 25 correspond to the passage of the hot-sticking and cutting strip structure in each transverse conveyor channel A 302, respectively.

[0066] like Figure 19 and Figure 20As shown, each guide block pad integral component 25 is divided into a connecting head 2501, a guide groove head 2502, and a pad portion 2503 connected together. The connecting head 2501 of each guide block pad integral component 25 is used to connect with the gear and rack transmission assembly. The guide groove head 2502 of each guide block pad integral component 25 is provided with a guide through groove 2504, which is used for the binding strap that first enters the longitudinal conveyor channel A 301 or the transverse conveyor channel A 302 to pass through. The pad portion 2503 of each guide block pad integral component 25 is used to move to the underside of the binding strap that re-enters the longitudinal conveyor channel A 301 or the transverse conveyor channel A 302, and is used to pad between the binding strap and the banknote when the hot-press cutting structure is working. When the strapping is released, the rack and pinion drive 26 actuates, moving the guide block pad 25 so that the strapping initially entering the longitudinal or transverse strapping channel A 301 or A 302 can pass through the corresponding guide slots 2504. When heat bonding is required, the rack and pinion drive 26 actuates again, moving the guide block pad 25. The pad portion 2503 of each guide block pad 25 moves to the underside of the strapping that has returned to the longitudinal or transverse strapping channel A 301 or A 302, and is used to pad between the strapping and the banknote during the heat bonding and cutting structure operation. Each heat-sealing head 1 presses the strapping to be heat-bonded onto the pad portion 2503 of the corresponding guide block pad 25, preventing excessive heat from the heat-sealing head 1 from being directly transferred to the banknote. This is especially suitable for bundling plastic banknotes, effectively preventing the plastic banknotes from melting due to excessive temperature during heat bonding.

[0067] In this embodiment, the driving end of the gear and rack drive 26 is connected to the gear and rack transmission assembly, thereby driving the movement of each guide block pad integral part 25. The gear and rack transmission assembly includes a driving gear 27, a driven gear 28, a transverse moving frame 29, and a longitudinal moving frame 30. The driving gear 27 and the driven gear 28 are rotatably mounted on the upper fixed plate 3. A transverse moving frame 29 is provided parallel to the width direction of the upper fixed plate 3, and two transverse moving frames 29 are provided parallel to the length direction of the upper fixed plate 3. One end of the transverse moving frame 29 is provided with a rack part A, and the other end is provided with a rack part B. One end of each longitudinal moving frame 30 is provided with a rack part C. The rack part B of the transverse moving frame 29 and the rack parts C of the two longitudinal moving frames 30 are respectively meshed with the driven gear 28. The rack part A of the transverse moving frame 29 is meshed with the driving gear 27. The driving gear 27 is connected to the driving end of the gear and rack drive 26. In this embodiment, the upper fixed plate 3 is provided with corresponding limiting grooves that cooperate with the two transverse moving frames 29 and the longitudinal moving frame 30 respectively, which can ensure that the transverse moving frame 29 and the longitudinal moving frame 30 move accurately and stably, and the overall structure is compact.

[0068] Specifically, such as Figure 13 and Figure 14 As shown, in this embodiment, the bottom surface of the upward-pushing coin plate 5 has a lower heating head through-hole at the intersection of the longitudinal conveyor channel B 501 and the two transverse conveyor channels B 502. Electromagnets 31 are mounted on the bottom surface of the upward-pushing coin plate 5 at the corresponding locations of each lower heating head through-hole via electromagnet mounting brackets 33. Each electromagnet 31 has a vertically upward-facing retractable drive end, and each drive end of the electromagnet 31 is connected to a lower heating head 32. Each lower heating head 32 is used to heat and adhere the binding strap at the intersection of the longitudinal conveyor channel B 501 and the two transverse conveyor channels B 502, i.e., the binding strap below the banknote stack 006. The electromagnets 31 are commercially available products. The specific structure of the lower heating head 32 can be basically the same as that of the upper heating head 1, and their actions are controlled by the controller of the banknote bundling machine. A structure similar to the movable guide pad structure on the upper fixed plate 3 can also be provided on the upward-pushing coin plate 5, and used in conjunction with the lower heating head 32, thus better suited for bundling plastic banknotes.
