Description

Technical Field

[0001] The present invention relates to the field of printing technology, in particular to a self-service device for printing test reports. Background Art

[0002] Self-service printing equipment can obtain paper information through manual input, scanning and other methods. When used in hospitals, the above-mentioned self-service printing equipment is generally used to print patients' medical records, test reports, registration forms, etc., which reduces the waiting time for manual registration, etc. and also improves the work efficiency of the hospital.

[0003] The existing Chinese patent with authorization announcement number CN213814866U discloses an artificial intelligence printing device for hospitals, including a cabinet, a touch screen installed on the cabinet door, a card reader, and a thermal printer arranged on the cabinet. The cabinet door is also provided with a thermal paper outlet of the thermal printer. An industrial computer is arranged in the cabinet, the industrial computer is connected to the main control computer, and the industrial computer is electrically connected to the thermal printer. When in use, the user inserts the medical insurance card into the medical insurance card reader, and triggers registration, payment and other operation instructions through the information displayed on the touch screen. The industrial computer receives the above instructions and controls the thermal printer to print, and outputs the printed registration form, payment form or other paper from the thermal paper outlet.

[0004] With respect to the above-mentioned related technologies, the inventors found that the thermal paper outlet for outputting printed paper is generally open. After long-term use, dust and other debris are easily accumulated on the inner wall of the outlet, which may cause subsequent paper to fail to be output smoothly, or cause subsequent output paper to be dirty or even jammed, so there is room for improvement. Summary of the invention

[0005] In order to ensure that clean printed paper can be smoothly output at the paper outlet of the printing device, the present application provides a self-service device for printing test reports.

[0006] This application provides a self-service device for printing test reports, which adopts the following technical solutions:

[0007] A self-service device for printing test reports comprises a cabinet and a printer body arranged in the cabinet, a paper outlet is formed through a side wall of the cabinet, a blocking block is arranged in the cabinet, the blocking block is inserted in the paper outlet and used to block the paper outlet, a connecting port is formed in the blocking block, the blocking block is rotatably connected to the paper outlet, and the connecting port can be connected to the paper outlet when the blocking block is rotated to a specified angle.

[0008] By adopting the above technical solution, when printing is not required, the blocking block can be turned to an angle where the connecting port and the paper outlet are not connected to each other. When printing is required, the blocking block is turned to a state where the paper outlet and the connecting port are connected. At this time, the paper output by the printer body can be output from the cabinet through the connecting port. Since the paper is output from the connecting port, even if dust is deposited on the inner wall of the paper outlet, when printing is not required, the connecting port and the paper outlet are in a state of being disconnected from each other, and the connecting port will not be affected by the settlement of dust. Only when printing is required, the connecting port will be connected to the paper outlet, that is, connected to the external environment. The above method reduces the possibility of the outlet for outputting paper (that is, the connecting port) being contaminated by dust, so that the paper can be output smoothly without being contaminated by dust.

[0009] Preferably, a cleaning scraper is also provided in the cabinet, the cleaning scraper is located in the paper outlet, and the cleaning scraper is located outside the blocking block, the cleaning scraper is attached to the outer surface of the blocking block, and the cleaning scraper is rotatably connected to the inner wall of the paper outlet; a cleaning mechanism is provided inside the cabinet, the cleaning mechanism is used to drive the cleaning scraper to rotate around the blocking block, and clean the outer surface of the blocking block during the rotation of the cleaning scraper.

[0010] By adopting the above technical solution, before the driving mechanism drives the blocking block to rotate so that the paper outlet is connected with the connecting port, the cleaning mechanism first drives the cleaning scraper to rotate with the blocking block as the center, and the outer surface of the blocking block is cleaned during the rotation of the cleaning scraper. After the cleaning is completed, the cleaning scraper is reset, thereby cleaning the paper outlet in the above manner and reducing dust in the paper outlet.

[0011] Preferably, a cavity is opened inside the cleaning scraper, and a dust suction port is opened on the side wall of the cleaning scraper facing the blocking block, and the dust suction port is connected with the cavity. The cleaning mechanism includes a suction fan, and the air inlet of the suction fan is connected with the cavity, and the air outlet of the suction fan is located outside the cavity.

[0012] By adopting the above technical solution, during the rotation of the cleaning scraper, the suction fan is started, and the cavity forms a negative pressure under the action of the suction fan. The dust attached to the outer surface of the blocking block will enter the cavity through the dust suction port under the action of suction, thereby achieving the dust removal effect of the blocking block by dust suction.

[0013] Preferably, the cleaning scraper includes two split plates symmetrically arranged in the paper outlet, the sealing block is located between the two split plates, and the cleaning mechanism includes a moving component for driving the two split plates to move away from or closer to each other, and a rotating component for driving the two split plates to rotate around the sealing block.

[0014] By adopting the above technical solution, before the outer surface of the blocking block is vacuumed by the vacuum fan, the two split plates are first driven to move in the direction of separation from each other by the moving component to form a gap between the split plates and the blocking block, and then the two split plates are driven to rotate with the blocking block as the center by the rotating component and vacuumed by the vacuum fan. The setting of the above moving component can optimize the vacuuming effect on the outer surface of the blocking block on the one hand, and prevent the blocking block from deflecting with the rotation of the split plates on the other hand.

[0015] Preferably, the cabinet body is provided with a clearance gap near the paper outlet, the clearance gap is located outside the paper outlet, the inner wall of the clearance gap is provided with an elastic cushion layer, and the side of the elastic cushion layer away from the inner wall of the clearance gap is connected to the side wall of the dividing panel.

[0016] By adopting the above technical solution, when the two sub-plates are close to each other to fit on the outer surface of the blocking block, the sub-plates are located in the paper outlet rather than in the clearance gap. In order to prevent the inside and outside of the cabinet from being connected due to the clearance gap, thereby preventing dust and debris outside the cabinet from entering the inside of the cabinet through the clearance gap, an elastic cushion layer is specially provided to fill the clearance gap. As the name implies, the elastic cushion layer is elastic. Therefore, when the two sub-plates are separated from each other, the elastic cushion layer is squeezed and compressed, and will not hinder the movement of the sub-plates.

[0017] Preferably, the moving assembly includes a moving sleeve, a push tube arranged on the side wall of each split plate, and a sliding member for driving the moving sleeve to slide along the height direction of the linkage frame; the rotating assembly includes a linkage frame rotatably connected to the inner wall of the paper outlet, a rack arranged on the end of the moving sleeve, and a gear set;

[0018] The movable sleeve is sleeved on the outside of the linkage frame, and a transition surface is provided at one end of the movable sleeve away from the sliding member, and the outer diameter of the movable sleeve located at the transition surface gradually increases toward the sliding member; the rack is provided at one end of the movable sleeve close to the transition surface, and the gear set is used to drive the linkage frame to rotate during the movement of the rack after contacting with the rack; each of the sub-plates is connected to the linkage frame, the push tube is sleeved on the linkage frame, and one end of the push tube is connected to the side wall of the corresponding sub-plate, and the other end is provided with a yield surface that abuts against the peripheral wall of the push tube.

[0019] By adopting the above technical solution, when the two sub-plates have not yet been separated, that is, when the side wall of the sub-plate is in contact with the outer surface of the blocking block, the push tube yielding surface is against the transition surface of the movable sleeve. At this time, the movable sleeve is driven to move through the sliding member so that the push tube yielding surface is in contact with the peripheral wall of the movable sleeve away from the transition surface. Since the outer diameter of the movable sleeve close to the transition surface is smaller than the outer diameter away from the transition surface, the push tube will be squeezed and pushed by the movable sleeve due to the increase in the outer diameter of the movable sleeve, and then the two sub-plates are pushed away from each other through the push tube. At this time, the telescopic member is stretched, and in the process of the movable sleeve continuing to move, the rack contacts the gear set, the gear drives the linkage frame to rotate, and the linkage frame drives the two sub-plates to rotate.

[0020] Preferably, the moving assembly also includes a telescopic sleeve arranged on the side wall of each sub-panel, and a reset spring arranged in the telescopic sleeve. The sub-panel is connected to the linkage frame through the telescopic sleeve. The telescopic direction of the telescopic sleeve and the telescopic direction of the reset spring are consistent with the direction in which the sub-panels separate or approach each other.

[0021] By adopting the above technical solution, the telescopic sleeve is arranged to not hinder the movement of the split plate when the push tube pushes against the split plate, and when the split plates move away from each other, the reset spring will be stretched. When the two split plates need to be restored to a state of being in contact with the blocking block, this can be achieved through the elastic action of the elastic cushion layer, that is, the split plates are driven closer to each other through the elastic force of the reset spring, so that the push tube is again against the transition surface, thereby achieving quick reset.

[0022] Preferably, the self-service test report printing device further comprises a linkage part, which is used to drive the blocking block to rotate after the dividing plate is rotated to a specified angle, so that the connecting port of the blocking block is connected to the paper outlet.

[0023] By adopting the above technical solution, a linkage is set up to drive the blocking block to rotate after the split plate rotates a specified angle. Therefore, before the printed paper material needs to be output, dust is first sucked by rotating the split plate, and then the blocking block is driven to rotate during the dust suction process.

[0024] Preferably, the linkage part includes an insertion block, a docking spring and a linkage rod; the insertion block is inserted into the bottom wall of one of the split panels, the docking spring is arranged between the bottom wall of the split panel and the insertion block, and the split panel with the insertion block and the other split panel are arranged sequentially along the rotation direction of the split panel; the linkage rod is arranged on the bottom wall of the blocking block, a rotating groove for the linkage rod to rotate is opened inside the cabinet, and a slot for the insertion of the insertion block is opened on the top of the linkage rod.

[0025] By adopting the above technical solution, the docking spring is always in a compressed state. When the dividing plate is rotated to a specified angle, the insert block is inserted into the slot. At this time, when the dividing plate continues to rotate, due to the setting of the insert block and the slot, the dividing plate can drive the blocking block to rotate with the blocking block as the center. When the connecting port is connected to the paper outlet, the sliding member can be used to stop the movement of the movable sleeve, thereby stopping the rotation of the dividing plate.

[0026] Preferably, the peripheral wall of the linkage rod and the peripheral wall of the insert block are both provided with magnet sheets, and the inner wall of the rotating groove and the inner wall of the slot are both provided with adsorption iron sheets that are magnetically attracted to the magnet sheets.

[0027] By adopting the above technical solution, the arrangement of the magnet sheet on the linkage rod can stop the linkage rod from rotating, thereby reducing the situation where the linkage rod rotates randomly under the influence of external vibration force. The arrangement of the magnet sheet on the plug block can achieve stable insertion of the plug block and the slot after the plug block is inserted into the slot, thereby reducing the situation where the plug block is separated from the slot when the split plate drives the blocking block to rotate.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. When printing is not required, the blocking block can be turned to an angle where the communication port and the paper outlet are not connected to each other. When printing is required, the blocking block is turned to a state where the paper outlet is connected to the communication port. At this time, the paper output by the printer body can be output from the cabinet through the communication port. Since the paper is output from the communication port, even if dust is deposited on the inner wall of the paper outlet, when printing is not required, the communication port and the paper outlet are not connected to each other, and the communication port will not be affected by dust settling. Only when printing is required, the communication port will be connected to the paper outlet, that is, connected to the external environment. The above method reduces the possibility that the outlet for outputting paper (that is, the communication port) is contaminated by dust, so that the paper can be output smoothly without being contaminated by dust.

[0030] 2. Before the driving mechanism drives the blocking block to rotate so that the paper outlet is connected with the connecting port, the cleaning mechanism drives the cleaning scraper to rotate around the blocking block, and the outer surface of the blocking block is cleaned during the rotation of the cleaning scraper. After the cleaning is completed, the cleaning scraper is reset, thereby cleaning the paper outlet and reducing dust in the paper outlet. BRIEF DESCRIPTION OF THE DRAWINGS

Each sub-plate 21 corresponds to a suction fan 31. A cavity 211 is opened inside each sub-plate 21. A dust suction port 212 is opened on the side wall of each sub-plate 21 facing the blocking block 13. The dust suction port 212 is connected with the cavity 211. The suction fan 31 is installed on the top of the corresponding sub-plate 21, and the inlet of the suction fan 31 is connected with the corresponding cavity 211. The air outlet of the suction fan 31 is connected with an air outlet duct, and the air outlet duct can pass through the cabinet 1 and be connected with the external space of the cabinet 1.

[0049] Reference Figure 5 , Figure 6 and Figure 7 The linkage member 22 includes an insert block 221, a docking spring 222 and a linkage rod 223, wherein a fixing groove 213 is opened on the bottom wall of one of the split plates 21, the insert block 221 and the docking spring 222 are both inserted into the fixing groove 213, and one end of the docking spring 222 is connected to the top wall of the fixing groove 213, and the other end is connected to the top wall of the insert block 221, and the docking spring 222 is always in a compressed state; when the movable sleeve 321 moves downward to make the linkage frame 331 rotate, the split plate 21 connected to the insert block 221 and the other split plate 21 are arranged sequentially along the rotation direction of the linkage frame 331.

[0050] Reference Figure 5 , Figure 6 and Figure 7 The linkage rod 223 is welded to the lower surface at the center of the blocking block 13, a rotation groove 132 is provided on the bottom wall of the paper outlet 11, the linkage rod 223 is "C"-shaped and inserted into the rotation groove 132; the rotation groove 132 is used for the linkage rod 223 to rotate when the linkage rod 223 rotates with the blocking block 13; a sliding hole is provided on the top wall of the paper outlet 11, the sliding hole is arc-shaped and communicated with the rotation groove 132, and one end of the linkage rod 223 away from the blocking block 13 is inserted into the sliding hole.

[0051] Reference Figure 5 , Figure 6 and Figure 7 A slot 2231 is provided on the upper surface of one end of the linkage rod 223 away from the blocking block 13, and the slot 2231 is located on the rotation path of the plug block 221, and when the split plate 21 rotates 90 degrees, the plug block 221 can be inserted into the slot 2231 driven by the docking spring 222, and the end face of the plug block 221 and the end wall of the linkage rod 223 near the notch of the slot 2231 are provided with an arc surface that is convenient for the plug block 221 to escape from the slot 2231; the outer surface of the linkage rod 223, the outer surface of the plug block 221 and the top peripheral wall of the linkage frame 331 are all welded with magnet sheets 23, and the inner wall of the rotating groove 223, the inner wall of the slot 2231 and the inner wall of the rotating connection between the cabinet 1 and the linkage frame 331 are all welded with adsorption iron sheets 24, and the adsorption iron sheets 24 are magnetically adsorbed to the magnet sheets 23 at the corresponding position.

[0052] The implementation principle of the self-service device for printing test reports in the embodiment of the present application is as follows: when there is no need to output the printed paper material, the connecting port 131 of the blocking block 13 can be turned to a state perpendicular to the length direction of the paper outlet 11 to reduce dust accumulation. When the printed paper material needs to be output, the blocking block 13 can be manually rotated by ninety degrees so that the connecting port 131 is connected to the paper outlet 11 to facilitate the output of the paper material. The blocking block 13 can also be rotated automatically. The specific operation is as follows:

[0053] After the thermal printer has finished printing, the cylinder and the suction fan 31 can be started by the industrial computer to control the movable sleeve 321 to move downward. During the downward movement of the movable sleeve 321, the two split plates 21 are first pushed away from each other by the push tube 322 to form a gap between the split plates 21 and the blocking block 13. At this time, the elastic cushion layer 121 is compressed and the telescopic sleeve 334 is stretched; then the movable sleeve 321 continues to move downward and makes the rack 332 contact with the gear set 333. At this time, the linkage frame 331 will drive the two split plates under the action of the gear set 333 and the rack 332 21 rotates. During the rotation of the dividing plate 21, the suction fan 31 sucks the dust on the outer surface of the blocking block 13 and the inner wall of the paper outlet 11 into the cavity 211 through the dust suction port 212 to achieve dust removal; when the dividing plate 21 rotates ninety degrees, the plug block 221 is inserted into the slot 2231. At this time, the dividing plate 21 continues to rotate, and the blocking block 13 rotates driven by the dividing plate 21 until the blocking block 13 stops when it rotates ninety degrees, so that the connecting port 131 is connected with the paper outlet 11, which is convenient for manual paper removal; the blocking block 13 can be controlled by the industrial computer to pause for a specified period of time after rotating ninety degrees and then reset.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
