Description

Technical Field

[0001] This application relates to the field of medical printers, and more particularly to a medical self-service receipt dispensing machine. Background Technology

[0002] With the development of advanced medical technology and medical imaging, patients in hospitals often use self-service document retrieval machines to obtain their diagnostic and laboratory test results as needed. These machines are frequently used in hospitals, and when they malfunction or other issues arise with the display, barcode scanning, or card reading modules, the cabinet needs to be opened for replacement or repair. In contrast, with existing self-service document retrieval machines, if the printer malfunctions or the display, barcode scanning, or card reading modules fail, the entire cabinet needs to be moved out and the rear panel opened before maintenance can be performed, making the maintenance process inconvenient.

[0003] To address the aforementioned issues, Chinese Patent No. CN207190567U discloses a medical self-service receipt dispensing machine. The machine comprises a cabinet containing a printer. A front cover is located at the upper front of the cabinet, with a touch-screen LCD display in the center. A front door is located at the lower front of the cabinet, with one side hinged to one side panel of the lower cabinet and the other side locked to the other side panel. A tray is located in the lower part of the cabinet. Side sliding grooves are located on the inner sides of the two side panels of the lower cabinet. Side sliding rails are fixedly connected to the two sides of the tray, guiding the side sliding grooves forward and backward. The printer is placed on the tray. A support baffle is located at the front of the tray, with one end hinged to the center of the front of the tray via a hinge pin, and the other end hanging above the tray on one side of the front of the cabinet.

[0004] When the printer inside the cabinet needs maintenance, the tray is pulled forward smoothly and reliably due to the cooperation of the side guide groove and side guide rail. When it is pulled to the rear end of the side guide rail, it is supported on the ground by the support baffle. The upper end of the support baffle is hinged to the front end of the tray. When the tray is inside the cabinet, the support baffle can be rotated around the hinge point and hung in the hanging hole at the lower front of the cabinet for easy maintenance.

[0005] The aforementioned technologies have the following drawbacks: when self-service order dispensing machines are placed in hospitals, the daily order volume is large, but the printer itself can only store a limited amount of paper. Therefore, it is necessary to repeatedly open the front door to place the paper into the printer, which is cumbersome and needs to be improved. Summary of the Invention

[0006] To address the inconvenience of refilling paper into a printer, this application provides a medical self-service paper dispensing machine.

[0007] The technical solution of the medical self-service receipt dispensing machine provided in this application is as follows:

[0008] A medical self-service paper dispensing machine includes a cabinet with a printer inside. A paper storage box is slidably connected inside the printer. A connection hole is provided through the side wall of the cabinet. A replenishment box for replenishing paper into the paper storage box is provided on the side wall of the cabinet. A support block for supporting the paper is slidably connected in the replenishment box. The paper storage box and the replenishment box are connected through the connection hole. The side of the paper storage box near the replenishment box abuts against the side wall of the support block. The printer is provided with a moving mechanism for driving the paper storage box to move. The moving mechanism includes a rotating component and a moving component. Both the rotating component and the moving component are connected to the printer. The rotating component is connected to the moving component via a connecting conveyor belt. The paper storage box is connected to the moving component. When the rotating component rotates, it drives the connecting conveyor belt to drive the moving component to rotate, thereby driving the paper storage box to insert into or remove from the replenishment box.

[0009] By employing the above technical solution, when the paper in the paper tray is low, rotating the rotating component causes the connecting conveyor belt to rotate, which in turn drives the moving component to rotate, moving the paper tray closer to the refill box. During this movement, the paper tray pushes the support block away from the printer until the paper tray is inserted into the refill box. This causes the paper that was initially in contact with the support block to fall onto the paper tray under gravity. Then, the support block is moved closer to the printer, simultaneously pushing the paper tray and the paper on it out of the refill box until the paper tray, along with the paper on it, is back in the printer. This eliminates the need for manual opening of the printer for frequent, small-volume paper refills, making the operation convenient.

[0010] Optionally, the rotating assembly includes a rotating conveyor belt, a rotating rod, and two rotating blocks. The rotating conveyor belt is rotatably connected to the printer. The two rotating blocks are evenly distributed on the rotating conveyor belt and are fixed to the outer side wall of the rotating conveyor belt. The rotating rod is rotatably connected to the printer and is parallel to the rotating conveyor belt. A rotating groove is provided on the side wall of the rotating rod. When the rotating block is inserted into the rotating groove and slides in the rotating groove, it drives the rotating rod to rotate. The drive wheel connected to the conveyor belt is coaxially fixed with the rotating rod.

[0011] By adopting the above technical solution, when there is little paper in the paper tray, the rotating conveyor belt is rotated, causing the rotating block to move along the length of the conveyor belt. This allows the rotating block to be inserted into the rotating groove from one end. The rotating conveyor belt continues to rotate, causing the rotating block to slide within the rotating groove. The inner wall of the rotating groove abuts against the side wall of the rotating block, guiding the rotating block so that it can only move along the trajectory of the rotating groove. This causes the rotating rod to rotate around its central axis, driving the connecting conveyor belt to rotate. This causes the moving component to rotate, thus moving the paper tray closer to the replenishment box until the paper tray pushes the support block to separate from the paper and is fully inserted into the replenishment box. This allows the paper in the replenishment box to fall onto the paper tray. The paper tray is then inserted back into the printer, achieving paper replenishment from the paper tray. The operation is convenient.

[0012] Optionally, the moving component includes a moving rod and a moving block. The moving rod is rotatably connected to the printer and coaxially fixed to the driven wheel of the connecting conveyor belt. The moving block is threaded onto the moving rod, and the paper storage box is fixed to the moving block.

[0013] By adopting the above technical solution, when the rotating conveyor belt drives the rotating block to move in the rotating groove, the rotating rod rotates, which in turn causes the connecting conveyor belt to rotate, driving the moving rod to rotate. Because the moving block and the moving rod are threaded together, the moving block moves along the length of the moving rod, thus realizing the movement of the paper tray. This allows the paper tray to be inserted into the refill box to replenish paper, and it can also be removed from the refill box and inserted back into the printer, enabling normal printer operation.

[0014] Optionally, the rotating conveyor belt is provided with a drive mechanism for driving the rotating conveyor belt to rotate. The drive mechanism includes a drive component and a rotating component. The drive component is connected to the paper storage box, and the rotating component is connected to the printer. The rotating component is connected to the drive wheel of the rotating conveyor belt through a pre-compression component. When the paper in the paper storage box decreases, the drive component drives the rotating component to rotate, which in turn drives the pre-compression component to rotate, causing the rotating conveyor belt to rotate and insert the paper storage box into the replenishment box. The replenishment box is provided with a reset component for pushing the paper storage box out of the replenishment box.

[0015] By adopting the above technical solution, when the paper in the paper tray decreases, the drive component moves, driving the rotating component to rotate, which in turn causes the pre-compression component to rotate, thus twisting and deforming the pre-compression component. When the paper in the paper tray decreases to a certain level, the pre-compression component loses its torsional force, recovers its deformation, and reverses direction, driving the rotating conveyor belt to rotate, causing the paper tray to insert into the replenishment box. After the paper tray is replenished with paper in the replenishment box, the reset component moves the paper tray closer to the printer until it is removed from the replenishment box. At this time, the support block re-inserts into the replenishment box and supports the paper inside, realizing automatic paper replenishment from the paper tray, which is convenient to operate.

[0016] Optionally, the driving assembly includes a driving block, a driving spring, a driving rack, and a driving gear. The driving block is slidably connected to the paper storage box, and the driving spring is disposed on the paper storage box to push the driving block away from the paper storage box. The driving block abuts against the paper on the paper storage box. The driving rack is fixed to the driving block. The driving gear is rotatably connected to the printer. The driving rack can mesh with the driving gear. The rotating assembly is fixed to the driving gear.

[0017] By adopting the above technical solution, when the paper in the paper tray of the printer decreases, the downward pressure on the drive block decreases. Under the action of the drive spring, the drive block moves continuously away from the ground, causing the drive rack to go from a state of separation from the drive gear to a state of engagement, and driving the drive gear to rotate. This, in turn, drives the rotating component to rotate, thus achieving the torsion of the pre-compression component. When the paper in the paper tray decreases to a certain amount, the drive rack moves to separate from the drive gear, the pre-compression component loses its torsional force, and returns to its original deformation, causing the rotating component and drive gear to reverse. At the same time, the pre-compression component comes into contact with the drive wheel of the rotating conveyor belt, driving the drive wheel of the rotating conveyor belt to rotate, thus achieving the rotation of the rotating conveyor belt. This transports the paper tray to the replenishment box, achieving automatic paper replenishment of the paper tray without the need for manual judgment of the amount of paper in the paper tray, making operation convenient.

[0018] Optionally, the rotating assembly includes a rotating bevel gear and a transmission bevel gear. The rotating bevel gear is coaxially fixed with the drive gear, and the transmission bevel gear meshes with the rotating bevel gear. The transmission bevel gear is connected to the drive wheel of the rotating conveyor belt through the preload assembly.

[0019] By adopting the above technical solution, when the drive rack moves to mesh with the drive gear and drives the drive gear to rotate, the rotating bevel gear drives the transmission bevel gear to rotate, thereby causing the pre-compression component to be twisted and deformed. When the drive rack moves to separate from the drive gear again, the pre-compression component restores its deformation, drives the rotating conveyor belt to rotate, and realizes the movement of the paper storage box.

[0020] Optionally, the preload assembly includes a rotating rod, a preload torsion spring, a ratchet, and a pawl. The rotating rod is fixed to the rotating assembly. One end of the preload torsion spring is connected to the rotating rod, and the other end is connected to the printer. The ratchet is coaxially fixed to the rotating rod. A rotating hole is provided through the side wall of the drive wheel of the rotating conveyor belt. The inner wall of the rotating hole is connected to the pawl through a reset torsion spring. The pawl is located between adjacent teeth on the ratchet.

[0021] By adopting the above technical solution, when the drive rack drives the drive gear to mesh and rotate, the transmission bevel gear drives the rotating rod to rotate, torsioning the preload torsion spring and causing it to deform. Simultaneously, the rotating rod drives the ratchet to rotate. During the ratchet's rotation, the sidewall of the ratchet teeth abuts against the sidewall of the pawl. The sidewall of the ratchet teeth acts as a guide, causing the reset torsion spring to deform and moving the pawl along the trajectory of the ratchet teeth's sidewall to the sidewall of the adjacent tooth on the ratchet. In other words, the pawl does not interfere with the rotation of the ratchet's torsion spring. When the drive rack moves to the point of disengagement from the drive gear, the drive gear loses its meshing locking force, causing the preload torsion spring to lose its torsional force and return to its original deformation. This causes the ratchet to reverse. At this time, the pawl abuts against the other side of the upper teeth of the ratchet. Under the action of the return torsion spring, the pawl is kept in contact with the side wall of the upper teeth of the ratchet. This causes the ratchet to reverse while driving the pawl to rotate, which in turn causes the conveyor belt to rotate, realizing the stored paper box's stored paper box to move with stored power. This eliminates the need for manual judgment of the amount of paper in the stored paper box, enabling automatic paper replenishment and making operation convenient.

[0022] Optionally, the reset assembly includes a reset drive and a reset button for controlling the opening and closing of the reset drive. The reset drive is fixed on the refill box, and the output end of the reset drive abuts against the side wall of the support block to push the support block toward the printer. The reset button is installed on the printer and is electrically connected to the reset drive. When the paper tray is inserted into the refill box, the drive rack is located directly above the reset button.

[0023] By adopting the above technical solution, after the paper tray is inserted into the refill box to replenish paper, the paper accumulates on the paper tray, applying downward pressure to the drive block, compressing the drive spring, and causing the drive rack to move downward until it abuts against the button. At this time, the reset drive is activated, and the drive support block pushes the paper tray towards the printer, thereby causing the paper tray to be pulled out of the refill box and reinserted into the printer, realizing the reset of the paper tray and completing the replenishment of paper on the paper tray. The operation is convenient.

[0024] Optionally, two support plates are rotatably connected to the inner wall of the supply box. The two support plates are symmetrical about the central axis of the supply box. A guide surface is provided on the side of the support plate away from the central axis of the supply box. The guide surface is connected to the side of the support plate away from the printer. The end of the guide surface near the support block is inclined towards the central axis of the supply box. Two abutment plates are provided on the support block. The two abutment plates are symmetrical about the central axis of the support block. The abutment plates abut against the side of the support plate away from the central axis of the supply box. The end of the support plate near the support block is inclined towards the central axis of the supply box.

[0025] By adopting the above technical solution, when the paper tray pushes the support block to move away from the printer, the abutment plate slides on the side of the support plate away from the central axis of the feed box, providing support for the support plate. This ensures that the support plate remains tilted towards the central axis of the feed box, supporting the paper inside the feed box. This reduces the possibility that some of the paper supported above the support block will lose support and fall during the movement of the support block, causing the paper inside the feed box to tilt. When the abutment plate separates from the support plate, i.e., when the paper tray is inserted into the feed box, the support plate loses its supporting force and naturally rotates downwards. This causes the paper above the support block in the feed box to simultaneously lose support and fall vertically onto the paper tray, increasing the neatness of the paper's descent and facilitating subsequent use of the paper on the paper tray.

[0026] After the paper in the paper tray is replenished, the reset drive moves the support block closer to the printer. The abutment plate abuts against the guide surface, which guides the paper. This causes the support plate to rotate about the axis of the connection between the support plate and the inner wall of the replenishment box, thus supporting the paper above the support block and separating the paper in the paper tray from the paper in the replenishment box. This makes it easier for the paper tray to move out of the replenishment box and is less affected by the pressure of the remaining paper in the replenishment box.

[0027] Optionally, the drive block is connected to the drive rack via a connecting rod, and the paper storage box is provided with a guide groove for the connecting rod to be inserted. The connecting rod is adapted to be inserted into the guide groove and slides in the guide groove.

[0028] By adopting the above technical solution, the guide groove abuts against the side wall of the connecting rod, which restricts the connecting rod and makes it less likely to deviate when the drive block moves the connecting rod. This allows the drive rack to move only in the vertical direction. That is, when the paper tray is inside the printer, the drive rack can mesh with the drive gear during its upward movement, increasing the accuracy of the meshing between the drive rack and the drive gear.

[0029] In summary, this application includes at least one of the following beneficial effects:

[0030] 1. When the paper tray has a low paper level, rotating the rotating assembly causes the connecting conveyor belt to rotate, which in turn rotates the moving assembly, moving the paper tray closer to the refill box. During this movement, the paper tray pushes the support block away from the printer until it inserts into the refill box. This causes the paper that was initially in contact with the support block to fall onto the paper tray under gravity. Then, the support block is moved closer to the printer, simultaneously pushing the paper tray and the paper on it out of the refill box until the paper tray and the paper on it are back in the printer. This eliminates the need for manual refilling of small amounts of paper multiple times, making the operation convenient.

[0031] 2. When the paper in the paper tray decreases, the drive component moves, causing the rotating component to rotate, which in turn causes the pre-compression component to rotate, resulting in its torsional deformation. When the paper in the paper tray reaches a certain level, the pre-compression component loses its torsional force, returns to its original deformation, and reverses direction, driving the rotating conveyor belt to rotate, causing the paper tray to insert into the replenishment box. After the paper tray is replenished with paper in the replenishment box, the reset component moves the paper tray closer to the printer until it is removed from the replenishment box. At this point, the support block re-inserts into the replenishment box and supports the paper inside, achieving automatic paper replenishment from the paper tray, which is convenient to operate.

Detailed Implementation

[0042] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0043] This application discloses a medical self-service receipt dispensing machine. (Refer to...) Figure 1 and Figure 2 The medical self-service paper dispensing machine includes a cabinet 1. A printer 2 is housed within the cabinet 1, and a paper storage box 3 is inserted into the printer 2, slidably connected to it. A supply box 4 is fixedly connected to the side wall of the printer 2, and the supply box 4 can hold a sufficient amount of paper for one day's hospital use.

[0044] Reference Figure 3 and Figure 4 A support block 401 is slidably connected inside the supply box 4, and the support block 401 is in the same direction of movement as the paper storage box 3. A connection hole 101 is provided through the side wall of the cabinet 1. The side of the support block 401 near the printer 2 passes through the connection hole 101 and abuts against the side wall of the paper storage box 3. The side of the support block 401 away from the ground is higher than the side of the paper storage box 3 away from the ground.

[0045] Reference Figure 3 and Figure 5In order to facilitate the movement of the paper storage box 3 in the printer 2 to the replenishment box 4 to replenish the paper on the paper storage box 3, a moving mechanism 5 is provided on the printer 2. The moving mechanism 5 includes a rotating component 501 and a moving component 502. The rotating component 501 is connected to the printer 2, and the moving component 502 is connected to the paper storage box 3. The rotating component 501 is connected to the moving component 502 through a connecting conveyor belt 6.

[0046] Reference Figure 5 and Figure 6 The rotating component 501 is provided with a driving mechanism 7, which includes a driving component 701 and a rotating component 702. The driving component 701 is connected to the paper storage box 3, and the rotating component 702 is connected to the printer 2. A pre-pressure component 8 is connected to the driving component 701, and the pre-pressure component 8 abuts against the rotating component 702.

[0047] When the paper in the paper tray 3 decreases, the drive assembly 701 moves away from the ground, causing the rotating assembly 702 to rotate, thereby twisting the pre-compression assembly 8 and giving it elastic potential energy. After the assembly moves up a certain distance, the drive assembly 701 separates from the rotating assembly 702, and the pre-compression assembly 8 loses its torsional force. During the reset process, the rotating assembly 702 reverses and comes into contact with the rotating assembly 501, causing the rotating assembly 501 to rotate. Under the transmission of the connecting conveyor belt 6, the moving assembly 502 rotates, thereby causing the paper tray 3 to push the support block 401 away from the printer 2 and insert it into the replenishment box 4. The paper in the replenishment box 4 above the support block 401 loses the support of the support block 401 and falls onto the paper tray 3, thus replenishing the paper in the paper tray 3.

[0048] Reference Figure 7 and Figure 8 To achieve the reset of the paper tray 3, a reset component 9 is provided on the refill box. After the paper tray 3 is inserted into the refill box 4 and the paper is refilled, the reset component 9 pushes the support block 401 to move closer to the printer 2, thereby pushing the refilled paper tray 3 to be reinserted into the printer 2. At this time, the support block 401 is also back in the refill box 4, supporting the paper in the refill box 4, realizing automatic paper refilling on the paper tray 3 in the printer 2, without the need for manual opening of the printer 2 to refill small amounts of paper multiple times.

[0049] Reference Figure 3 and Figure 5The rotating assembly 501 includes a rotating conveyor belt 5011, a rotating rod 5012, and two rotating blocks 5013. The rotating conveyor belt 5011 is arranged along the moving direction of the paper storage box 3 and is rotatably connected to the printer 2. The two rotating blocks 5013 are evenly distributed on the rotating conveyor belt 5011 and are glued to the outer side wall of the rotating conveyor belt 5011. The rotating rod 5012 is rotatably connected to the printer 2 and is parallel to the rotating conveyor belt 5011. A rotating groove 50121 is provided on the side wall of the rotating rod 5012. The rotating groove 50121 is spirally opened along the circumferential side wall of the rotating rod 5012. When the rotating blocks 5013 are inserted into the rotating groove 50121 and slide in the rotating groove 50121, the rotating rod 5012 is driven to rotate. The drive wheel of the connecting conveyor belt 6 is coaxially fixed with the rotating rod 5012.

[0050] When the paper in the paper storage box 3 is low, the rotating conveyor belt 5011 is rotated, causing the rotating block 5013 to move along the length of the rotating conveyor belt 5011. This allows the rotating block 5013 to be inserted into the rotating groove 50121 from one end. The rotating conveyor belt 5011 continues to rotate, causing the rotating block 5013 to slide within the rotating groove 50121. The inner wall of the rotating groove 50121 abuts against the side wall of the rotating block 5013, guiding the rotating block 5013. 5013 can only move along the trajectory of the rotating groove 50121, so that the rotating rod 5012 rotates around the central axis of the rotating rod 5012, driving the connecting conveyor belt 6 to rotate, causing the moving component 502 to rotate, thereby driving the paper storage box 3 to move towards the replenishment box 4, until the paper storage box 3 pushes the support block 401 to separate from the paper and is fully inserted into the replenishment box 4, so that the paper in the replenishment box 4 falls onto the paper storage box 3, and then the paper storage box 3 is inserted back into the printer 2 to realize the replenishment of paper on the paper storage box 3.

[0051] Reference Figure 3 and Figure 5 The moving component 502 includes a moving rod 5021 and a moving block 5022. The moving rod 5021 is rotatably connected to the printer 2 and parallel to the rotating rod 5012. The moving rod 5021 is coaxially fixed to the driven wheel of the connecting conveyor belt 6. The moving block 5022 is threaded onto the moving rod 5021. The side of the paper tray 3 closest to the ground is welded to the moving block 5022. When the rotating rod 5012 rotates, the connecting conveyor belt 6 rotates, causing the moving rod 5021 to rotate. Because the moving block 5022 is threaded onto the moving rod 5021, the moving block 5022 moves along the length of the moving rod 5021, thereby moving the paper tray 3. This allows the paper tray 3 to be inserted into the refill box 4 to refill paper, and it can also be removed from the refill box 4 and inserted back into the printer 2, enabling the printer 2 to operate normally.

[0052] Reference Figure 5and Figure 6 The drive assembly 701 includes a drive block 7011, a drive spring 7012, a drive rack 7013, and a drive gear 7014. A drive hole 301 is provided on the side of the paper tray 3 away from the ground. The drive block 7011 is inserted into the drive hole 301 and slides within it. The drive spring 7012 is located between the drive block 7011 and the inner wall of the drive hole 301 on the side closest to the ground, and is used to push the drive block 7011 away from the paper tray 3. The side of the drive block 7011 away from the ground abuts against the paper on the paper tray 3. The drive block 7011 is connected to the drive rack 7013. The drive gear 7014 is rotatably connected to the printer 2, and the drive rack 7013 can mesh with the drive gear 7014. The rotating assembly 702 is connected to the drive gear 7014.

[0053] When the amount of paper in the paper tray 3 of printer 2 decreases, the downward pressure on the drive block 7011 decreases. Under the action of the drive spring 7012, the drive block 7011 moves continuously away from the ground, causing the drive rack 7013 to move from a state of disengagement from the drive gear 7014 to a state of engagement, and driving the drive gear 7014 to rotate. This, in turn, drives the rotating component 702 to rotate, thus achieving the torsion of the pre-pressure component 8. When the amount of paper in the paper tray 3 decreases to a certain level, the drive rack 7013 moves to disengage from the drive gear 7014, the pre-pressure component 8 loses its torsional force, and returns to its original deformation, causing the rotating component 702 and the drive gear 7014 to reverse. As the pre-pressure component 8 reverses, it comes into contact with the drive wheel of the rotating conveyor belt 5011, driving the drive wheel of the rotating conveyor belt 5011 to rotate, thus achieving the rotation of the rotating conveyor belt 5011 and transporting the paper tray 3 to the replenishment box 4.

[0054] Reference Figure 5 To ensure the stability of the drive rack 7013's up-and-down movement, a connecting rod 13 is welded to the drive block 7011. The end of the connecting rod 13 away from the drive block 7011 is fixed to the drive rack 7013. A guide groove 302 is provided on the drive block 7011 along the vertical direction. The guide groove 302 is connected to the drive hole 301. The connecting rod 13 is adapted to be inserted into the guide groove 302 and slides in the guide groove 302.

[0055] The guide groove 302 abuts against the side wall of the connecting rod 13, which restricts the connecting rod 13 so that it is not easy to deviate when the driving block 7011 drives the connecting rod 13 to move. This allows the driving rack 7013 to move only in the vertical direction. That is, when the paper storage box 3 is located inside the printer 2, the driving rack 7013 can mesh with the driving gear 7014 during the upward movement.

[0056] Reference Figure 6The rotating assembly 702 includes a rotating bevel gear 7021 and a transmission bevel gear 7022. The rotating bevel gear 7021 is coaxially fixed with the drive gear 7014, and the transmission bevel gear 7022 meshes with the rotating bevel gear 7021. The transmission bevel gear 7022 is connected to the drive wheel of the rotating conveyor belt 5011 via the preload assembly 8.

[0057] When the drive rack 7013 moves to mesh with the drive gear 7014 and drives the drive gear 7014 to rotate, the rotating bevel gear 7021 drives the transmission bevel gear to rotate, thereby causing the pre-compression component 8 to be twisted and deformed. When the drive rack 7013 moves to separate from the drive gear 7014 again, the pre-compression component 8 recovers its deformation and drives the rotating conveyor belt 5011 to rotate, thereby realizing the movement of the paper storage box 3.

[0058] Reference Figure 4 and Figure 6 The preload assembly 8 includes a rotating rod 801, a preload torsion spring 802, a ratchet 803, and a pawl 804. The rotating rod 801 is fixed to the rotating assembly 702. The preload torsion spring 802 is sleeved on the rotating rod 801, with one end of the preload torsion spring 802 abutting and fixed to the rotating rod 801 and the other end abutting and fixed to the printer 2. The ratchet 803 is coaxially fixed to the rotating rod 801. The end wall of the drive wheel of the rotating conveyor belt 5011 has a through-hole. A rotating rod is fixed on the inner wall of the rotating hole. A reset torsion spring 10 is sleeved on the rotating rod. One end of the reset torsion spring 10 is fixed to the inner wall of the rotating hole, and the other end is fixed to the pawl 804. The pawl 804 is located between adjacent teeth on the ratchet 803.

[0059] When the drive rack 7013 drives the drive gear 7014 to mesh and rotate, the transmission bevel gear 7022 drives the rotating rod 801 to rotate, torsioning the preloaded torsion spring 802, causing the preloaded torsion spring 802 to deform. Simultaneously, the rotating rod 801 drives the ratchet 803 to rotate. During the rotation of the ratchet 803, the sidewall of the upper teeth of the ratchet 803 abuts against the sidewall of the pawl 804. The sidewall of the upper teeth of the ratchet 803 acts as a guide, causing the reset torsion spring 10 to deform and driving the pawl 804 to move along the trajectory of the sidewall of the upper teeth of the ratchet 803 to the sidewall of the adjacent tooth on the ratchet 803. In other words, the pawl 804 does not interfere with the rotation of the ratchet 803 torsion spring 802.

[0060] When the drive rack 7013 moves to the point of disengagement from the drive gear 7014, the drive gear 7014 loses its meshing locking force, causing the preload torsion spring 802 to lose its torsional force and recover its deformation, driving the ratchet 803 to reverse. At this time, the pawl 804 abuts against the other side of the upper tooth of the ratchet 803. Under the action of the reset torsion spring 10, the pawl 804 is kept in contact with the side wall of the upper tooth of the ratchet 803, so that the ratchet 803 reverses and drives the pawl 804 to rotate, thereby causing the rotating conveyor belt 5011 to rotate, realizing the stored paper box 3 to move with stored power. The paper in the stored paper box 3 can be automatically replenished without the need for manual judgment of the amount of paper in the stored paper box 3, which is convenient to operate.

[0061] Reference Figure 7 and Figure 8 The reset assembly 9 includes a reset drive 901 and a reset button 902 for controlling the opening and closing of the reset drive 901. In this embodiment, the reset drive 901 is a cylinder, and is fixedly mounted on the supply box 4 by bolts. The output end of the reset drive 901 abuts against the side wall of the support block 401, for pushing the support block 401 toward the printer 2. The reset button 902 is mounted on the printer 2 and is electrically connected to the reset drive 901. When the paper tray 3 is inserted into the supply box 4, the drive rack 7013 is located directly above the reset button 902.

[0062] After the paper tray 3 is inserted into the refill box 4 to refill paper, the paper accumulates on the paper tray 3, applying downward pressure to the drive block 7011 and compressing the drive spring 7012. This causes the drive rack 7013 to move downward until it abuts against the button. At this time, the reset drive 901 is activated, and the drive support block 401 pushes the paper tray 3 towards the printer 2. At this time, the rotating block 5013 is in the state of being withdrawn from the rotating slot 50121, so that the movement of the paper tray 3 drives the moving rod 5021 to rotate while driving the rotating rod 5012 to rotate, but does not drive the rotating conveyor belt 5011 to rotate. That is, the pre-compression torsion spring 802 will not be torn, so that the paper tray 3 is finally withdrawn from the refill box 4 and reinserted into the printer 2, realizing the reset of the paper tray 3 and completing the refilling of paper on the paper tray 3.

[0063] Reference Figure 7 and Figure 9To prevent the paper in the supply box 4 from tilting and falling during the movement of the support block 401, two support plates 11 are rotatably connected to the inner wall of the supply box 4. The two support plates 11 are symmetrical about the central axis of the supply box 4. A guide surface 1101 is cut on the side of the support plate 11 away from the central axis of the supply box 4. The guide surface 1101 is connected to the side of the support plate 11 away from the printer 2. The end of the guide surface 1101 near the support block 401 is inclined towards the central axis of the supply box 4. Two abutment plates 12 are welded on the support block 401. The abutment plates 12 are parallel to the support plate 11. The two abutment plates 12 are symmetrical about the central axis of the support block 401. When the abutment plate 12 abuts against the side of the support plate 11 away from the central axis of the supply box 4, the end of the support plate 11 near the support block 401 is inclined towards the central axis of the supply box 4.

[0064] When the paper tray 3 pushes the support block 401 to move away from the printer 2, the abutment plate 12 slides on the side of the support plate away from the central axis of the supply box 4, supporting the support plate 11. This keeps the support plate 11 tilted towards the central axis of the supply box 4, supporting the paper inside the supply box 4. This prevents the unsupported portion of the paper from tilting and falling during the movement of the support block 401. When the abutment plate 12 separates from the support plate 11, i.e., when the paper tray 3 is inserted into the supply box 4, the support plate 11 loses its support and rotates downwards. This causes the paper above the support block 401 in the supply box 4 to lose its support and fall vertically onto the paper tray 3, increasing the uniformity of the paper's downward movement within the supply box 4.

[0065] After the paper in the paper tray 3 is replenished, the reset drive 901 drives the support block 401 to move closer to the printer 2. The abutment plate 12 abuts against the guide surface 1101, which acts as a guide, causing the support plate 11 to rotate about the connection between the support plate 11 and the inner wall of the replenishment box 4, towards the central axis of the replenishment box 4. During the rotation, the edges of some paper may be bent, but this will not affect the normal use of the paper. When the support block 401 is tilted, it supports the paper above the support block 401, separating the paper in the paper tray 3 and the replenishment box 4, making it easier for the paper tray 3 to move out of the replenishment box 4 and less susceptible to pressure from the remaining paper in the replenishment box 4.

[0066] The implementation principle of a medical self-service receipt dispensing machine according to an embodiment of this application is as follows: When there is little paper in the paper storage box 3, the rotating conveyor belt 5011 is rotated, causing the rotating block 5013 to move along the length of the rotating conveyor belt 5011. This allows the rotating block 5013 to be inserted into the rotating groove 50121 from one end. The rotating conveyor belt 5011 continues to rotate, causing the rotating block 5013 to slide within the rotating groove 50121. The inner wall of the rotating groove 50121 abuts against the side wall of the rotating block 5013, guiding the rotating block 5013. 013 can only move along the trajectory of the rotating groove 50121, causing the rotating rod 5012 to rotate around its central axis, driving the connecting conveyor belt 6 to rotate, which in turn causes the moving rod 5021 to rotate. Because the moving block 5022 is threadedly engaged with the moving rod 5021, the moving block 5022 moves along the length of the moving rod 5021, causing the paper tray 3 to push the support block 401 away from the printer 2 until the paper tray 3 is inserted into the replenishment box 4. This causes the paper, which was originally in contact with the support block 401, to fall onto the paper tray 3 under gravity. Then, the support block 401 is moved closer to the printer 2, simultaneously pushing the paper tray 3 and the paper on it out of the replenishment box 4 until the paper tray 3 and the paper on it are back in the printer 2. This eliminates the need for manual opening of the printer 2 for frequent, small-volume paper replenishment, making operation convenient.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
