Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to a printer paper feeder. Background Technology

[0002] With the development of digitalization and informatization in various industries, intelligent service solutions have been widely used, such as smart healthcare, smart banking, and smart government. These intelligent services all rely on intelligent self-service equipment. Among these self-service devices, printing devices are well-known as a widely used device. In existing self-service printers, there is a paper dispensing slot on the machine body and a printing device inside the mechanism. However, there is a certain distance between the paper output slot and the paper dispensing slot of the printing device, which requires a paper feeder to assist in the paper delivery.

[0003] However, printers do not always print on the same size of paper. For example, when the printer prints on large-sized paper (such as A4), the printed paper may be fed directly out of the paper tray by the paper feeder, causing the printed paper to fall to the ground, which is not practical. Utility Model Content

[0004] The main purpose of this invention is to provide a printer paper feeder that addresses the issue of large-sized paper easily falling to the ground after entering the paper feeding channel and being transported by the paper feeder.

[0005] To achieve the above objectives, the printer paper feeder proposed in this utility model includes:

[0006] The mounting housing has a paper feeding channel, in which a first paper feeding area and a second paper feeding area are provided. The second paper feeding area covers the first paper feeding area, and the width of the second paper feeding area is greater than the width of the first paper feeding area.

[0007] The control module is located in the mounting housing;

[0008] A paper feeding structure, disposed within the paper feeding channel and electrically connected to the control module, is used to feed printed paper that has entered the paper feeding channel out from the output end of the output channel; and

[0009] A first sensor is located in the first paper feeding area and is electrically connected to the control module. The first sensor is used to detect whether printed paper has entered the paper feeding channel.

[0010] The second sensor is located in the second paper feeding area and outside the first paper feeding area. The second sensor and the first sensor are spaced apart in the width direction of the paper feeding channel. The second sensor is electrically connected to the control module. The second sensor is used to detect whether there is a printed sheet of paper entering the paper feeding channel.

[0011] The control module is configured to control the paper feeding structure to start feeding when it receives an electrical signal from the first sensor, and the control module is also configured to control the paper feeding structure to stop feeding when it receives electrical signals from both the first sensor and the second sensor at the same time.

[0012] Optionally, the first paper feeding area is located in the middle of the second paper feeding area.

[0013] Optionally, the sensor is an infrared diffuse reflection sensor.

[0014] Optionally, the paper feeding structure includes a drive motor, a drive gear, multiple driven gears, and multiple transmission rollers. The drive motor is located on the mounting housing, the drive gear is located on the output shaft of the drive motor, and the multiple driven gears are respectively located on two opposite side walls of the paper feeding channel and arranged along the length of the paper feeding channel. Adjacent driven gears mesh with each other, and each transmission roller is correspondingly installed between two driven gears. The multiple driven gears transmit power between the drive gear and the multiple transmission rollers.

[0015] Optionally, the sidewall of the paper feeding channel is provided with a blocking part, which is located above the driven gear and the driving gear and spaced apart from the driven gear and the driving gear, and the blocking part blocks the driven gear and the driving gear.

[0016] Optionally, the blocking part includes an integrally formed first blocking section and second blocking sections located at both ends of the first blocking section. The first blocking section is located above the driven gear and the driving gear, and both second blocking sections extend toward the bottom wall of the paper feeding channel and are spaced apart from the bottom wall of the paper feeding channel.

[0017] Optionally, the mounting housing includes a base plate and mounting plates located on opposite sides of the base plate, forming the paper feeding channel between the base plate and the two mounting plates, and both the first sensor and the second sensor are mounted on the base plate.

[0018] This utility model also proposes a self-service printer, characterized in that it includes a cabinet, a printing control device, a printing device, and a printer paper feeder as described above. The cabinet is provided with a paper pick-up port, which is connected to the interior of the cabinet. The printing control device is installed in the cabinet, and the printing device is installed inside the cabinet and electrically connected to the printing control device. The receiving end of the printer paper feeder corresponds to the paper output port of the printing device, and the feeding end of the printer paper feeder corresponds to the paper pick-up port.

[0019] Optionally, the printing device has a paper output channel and a paper output port communicating with the paper output channel, the receiving end of the printer paper feeder is inserted into the paper output channel, and the outer wall of the printer paper feeder abuts against the channel wall of the paper output channel.

[0020] Optionally, the self-service printer further includes a paper storage structure with a paper storage channel. The receiving end of the paper storage channel corresponds to the feeding end of the printer's paper feeder, and the feeding end of the paper storage structure corresponds to the paper dispensing port.

[0021] Optionally, the self-service printer further includes a baffle located at the paper dispensing slot for opening and closing the paper dispensing slot.

[0022] This utility model's technical solution includes a paper feeding channel within a mounting housing, comprising a first paper feeding area and a second paper feeding area. The second paper feeding area covers the first paper feeding area, and the width of the second paper feeding area is greater than that of the first paper feeding area. A control module is located within the mounting housing, and a paper feeding structure is positioned within the paper feeding channel to feed printed paper from the output end of the output channel. A first sensor is located in the first paper feeding area and electrically connected to the control module, detecting whether printed paper has entered the paper feeding channel. A second sensor is located in the second paper feeding area, outside the first paper feeding area, and electrically connected to the control module, also detecting whether printed paper has entered the paper feeding channel. The control module is configured to start the paper feeding structure when it receives an electrical signal from the first sensor, and to stop the paper feeding structure when it simultaneously receives electrical signals from both the first and second sensors. When printing on small-sized paper (e.g., photo paper), the printed paper enters the paper feed channel from the receiving end and is located in the first paper feed area. The first sensor detects this and sends an electrical signal to the control module. Upon receiving this signal, the control module activates the paper feed mechanism to move the printed paper from the output end of the paper feed channel to the paper pick-up point. When printing on large-sized paper (e.g., A4), the paper enters the paper feed channel from the receiving end and simultaneously covers both the first and second paper feed areas. Both sensors detect this and simultaneously send electrical signals to the control module. Upon receiving these signals, the control module stops the paper feed mechanism, allowing the printed paper to automatically slide to the paper pick-up point. This prevents large-sized printed papers from falling to the bottom after entering the paper feeding channel, thus improving the practicality of the printer's paper feeder.

[0037] This utility model proposes a printer paper feeder.

[0038] In the embodiments of this utility model, such as Figures 1 to 2 As shown, the printer paper feeder includes a mounting housing 10, a control module, a paper feeding structure 20, and two sensors.

[0039] Specifically, the mounting housing 10 has a paper feeding channel 11, within which are a first paper feeding area 111 and a second paper feeding area 112. The second paper feeding area 112 covers the first paper feeding area 111, and the width of the second paper feeding area 112 is greater than the width of the first paper feeding area 111. That is, when the printing device 60 prints small-sized paper (e.g., photo paper), the printed paper is transported within the first paper feeding area 111. When the printing device 60 prints large-sized paper (e.g., A4), the printed paper can cover the entire second paper feeding area 112, meaning the printed paper simultaneously covers both the first and second paper feeding areas 111 and 112. Optionally, the first paper feeding area 111 is located in the middle of the second paper feeding area 112.

[0040] The control module is located in the mounting housing 10; the paper feeding structure 20 is located in the paper feeding channel 11 and is electrically connected to the control module. The paper feeding structure 20 is used to feed the paper that has been printed in the paper feeding channel 11 out from the output end of the paper feeding channel 11.

[0041] The first sensor 30 is located in the first paper feeding area 111 and is electrically connected to the control module. The first sensor 30 is used to detect whether there is a printed paper entering the paper feeding channel 11, and sends an electrical signal to the control module when it detects that paper has entered the paper feeding channel 11.

[0042] The second sensor 40 is located in the second paper feeding area 112 and outside the first paper feeding area 111. That is, the second sensor 40 and the first sensor 30 are spaced apart in the width direction of the paper feeding channel 11. The second sensor 40 is electrically connected to the control module. The second sensor 40 is used to detect whether there is a printed sheet of paper entering the paper feeding channel 11, and sends an electrical signal to the control module when it detects that a sheet of paper has entered the paper feeding channel 11.

[0043] The control module is configured to start the paper feeding structure 20 to feed when it receives an electrical signal from the first sensor 30, and is also configured to stop the paper feeding structure 20 to feed when it receives electrical signals from both the first sensor 30 and the second sensor 40 at the same time.

[0044] When the control module receives an electrical signal from the first sensor 30, it means that a printed sheet has entered the first paper feeding area 111 of the paper feeding channel 11. At this time, the control module will control the paper feeding structure 20 to start working and start the conveying of the printed sheet to send the printed sheet from the feed end of the paper feeding channel 11 to the paper pick-up port.

[0045] When the control module receives electrical signals from the first sensor 30 and the second sensor 40 at the same time, it indicates that printed paper has entered the paper feeding channel 11 and simultaneously covers the first paper feeding area 111 and the second paper feeding area 112. At this time, the control module will control the paper feeding structure 20 to stop feeding.

[0046] Specifically, when the printing device 60 finishes printing small-sized paper (e.g., photo paper), the printed paper enters the paper feeding channel 11 from the receiving end of the paper feeding channel 11. At this time, the printed paper is located in the first paper feeding area 111. After the first sensor 30 detects the printed paper located in the first paper feeding area 111, it sends an electrical signal to the control module. When the control module receives the electrical signal sent by the first sensor 30, it controls the paper feeding structure 20 to start working and starts the conveying operation of the printed paper to send the printed paper from the output end of the paper feeding channel 11 to the paper pick-up port.

[0047] When the printing device 60 finishes printing a large-size sheet of paper (e.g., A4), the paper enters the paper feeding channel 11 from the receiving end of the paper feeding channel 11 and simultaneously covers the first paper feeding area 111 and the second paper feeding area 112. Thus, it is simultaneously detected by the first sensor 30 and the second sensor 40. When the first sensor 30 and the second sensor 40 simultaneously detect the finished paper, the first sensor 30 and the second sensor 40 will simultaneously send electrical signals to the control module. When the control module simultaneously receives the electrical signals sent by the first sensor 30 and the second sensor 40, it will control the paper feeding structure 20 to stop feeding, so that the finished paper automatically slides to the paper pick-up port.

[0048] This utility model's technical solution includes a paper feeding channel 11 within the mounting housing 10, and a first paper feeding area 111 and a second paper feeding area 112 within the paper feeding channel 11. The second paper feeding area 112 covers the first paper feeding area 111, and the width of the second paper feeding area 112 is greater than the width of the first paper feeding area 111. A control module is located within the mounting housing 10. A paper feeding structure 20 is located within the paper feeding channel 11 to feed the printed paper from the output end of the output channel. A first sensor 30 is located in the first paper feeding area 111 and is electrically connected to the control module. Next, the first sensor 30 is used to detect whether printed paper has entered the paper feeding channel 11. The second sensor 40 is set in the second paper feeding area 112 and located outside the first paper feeding area 111. The second sensor 40 is electrically connected to the control module. The second sensor 40 is used to detect whether printed paper has entered the paper feeding channel 11. The control module is set to control the paper feeding structure 20 to start feeding when it receives an electrical signal sent by the first sensor 30, and to control the paper feeding structure 20 to stop feeding when it receives electrical signals sent by both the first sensor 30 and the second sensor 40. When the printed paper is small (e.g., photo paper), when the printed paper enters the paper feeding channel 11 from the receiving end, the printed paper is located in the first paper feeding area 111. After the first sensor 30 detects the printed paper located in the first paper feeding area 111, it sends an electrical signal to the control module. When the control module receives the electrical signal sent by the first sensor 30, it controls the paper feeding structure 20 to start working, so as to feed the printed paper from the output end of the paper feeding channel 11 to the paper pick-up port. When the printing device 60 finishes printing a large-sized sheet of paper (e.g., A4), as the paper enters the paper feeding channel 11 from the receiving end, it simultaneously covers the first paper feeding area 111 and the second paper feeding area 112. The first sensor 30 and the second sensor 40 simultaneously detect the printed paper and send electrical signals to the control module. When the control module receives these signals, it stops the paper feeding structure 20, allowing the printed paper to automatically slide to the paper pick-up point. This prevents large-sized printed paper from falling to the bottom surface after entering the paper feeding channel 11, thus improving the practicality of the printer's paper feeder.

[0049] In some embodiments, the first sensor 30 is an infrared diffuse reflection type sensor. Specifically, infrared diffuse reflection type sensors have advantages such as fast response speed, strong anti-interference ability, and convenient installation. When applied in this solution, they are beneficial to improving detection stability and detection speed. The infrared sensor model can be ITR001 infrared reflective photoelectric sensor, GP2AP002S00F infrared proximity sensor, LTH-1550-01 reflective photoelectric sensor, etc.

[0050] In some embodiments, the second sensor 40 is an infrared diffuse reflection sensor. Infrared diffuse reflection sensors have advantages such as fast response speed, strong anti-interference capability, and convenient installation. When applied in this solution, they help improve detection stability and detection speed. The infrared sensor model can be ITR001 infrared reflective photoelectric sensor, GP2AP002S00F infrared proximity sensor, LTH-1550-01 reflective photoelectric sensor, etc.

[0051] In some embodiments, the paper feeding structure 20 includes a drive motor 21, a drive gear 22, a plurality of driven gears 23, and a plurality of transmission rollers 24. The drive motor 21 is disposed on the mounting housing 10. The drive gear 22 is provided with the output shaft of the drive motor 21. The plurality of driven gears 23 are disposed on two opposite side walls of the paper feeding channel 11 and arranged along the length direction of the paper feeding channel 11. Adjacent gears mesh with each other. Each transmission roller 24 is correspondingly installed between two driven gears 23. The plurality of driven gears 23 transmit power between the drive gear 22 and the plurality of transmission rollers 24.

[0052] Specifically, gear transmission has strong stability. When applied to this solution, the driving gear 22 is driven to rotate, which in turn drives the driven gear 23 to rotate. The rotation of the driven gear 23 drives the transmission roller 24 to rotate, which helps to improve the working stability of the paper feeding structure 20, that is, to improve the paper conveying stability.

[0053] In other embodiments, the paper feeding structure 20 includes a drive motor 21, a drive roller, a driven roller, and a conveyor belt. The drive motor 21 is mounted on the mounting housing 10. The drive roller and the driven roller are rotatably mounted between two opposite channel walls of the paper feeding channel 11 and are spaced apart from each other. The drive roller is connected to the output shaft of the drive motor 21, and the conveyor belt is sleeved between the drive roller and the driven roller.

[0054] In some embodiments, the sidewall of the paper feed channel 11 is provided with a blocking portion 14. The blocking portion 14 is located above and spaced apart from the driven gear 23 and the driving gear 22, thus blocking the driven gear 23 and the driving gear 22. Specifically, the blocking portion 14 is opposite to the bottom wall of the paper feed channel 11, that is, the driven gear 23 and the driving gear 22 are located between the bottom wall of the paper feed channel 11 and the blocking portion 14. The blocking portion 14 forms a barrier above the driven gear 23 and the driving gear 22, preventing objects from falling between two adjacent gears and affecting the rotation of the gears, which helps to improve the stability of the paper feed structure 20. In addition, in other embodiments, the sidewall of the paper feed channel 11 is not provided with a blocking portion 14.

[0055] In some embodiments, the blocking portion 14 includes an integrally formed first blocking section 141 and second blocking sections 142 located at both ends of the first blocking section 141. The first blocking section 141 is located above the driven gear 23 and the driving gear 22. Both second blocking sections 142 extend toward the bottom wall of the paper feeding channel 11 and are spaced apart from the bottom wall of the paper feeding channel 11. Specifically, the two second blocking sections 142 are used to form blocking on the front and rear sides of the gear, respectively. The two second blocking sections 142 are used to prevent the printed paper from getting caught in the gear and to prevent the user's hand from contacting the gear when picking up the printed paper, thereby improving the stability of the printed paper feeding.

[0056] In some embodiments, the mounting housing 10 includes a base plate 12 and mounting plates 13 located on opposite sides of the base plate 12, forming a paper feeding channel 11 between the base plate 12 and the two mounting plates 13. The first sensor 30 and the second sensor 40 are both mounted on the base plate 12. Specifically, the arrangement of the base plate 12 and the two mounting plates 13 simplifies the structure of the mounting housing 10, making it easier to manufacture and assemble. Mounting the first sensor 30 and the second sensor 40 on the base plate 12 reduces the installation difficulty of the first sensor 30 and the second sensor 40. Optionally, the base plate 12 and the two mounting plates 13 are integrally formed.

[0057] This utility model also proposes a self-service printer, such as... Figures 3 to 7 As shown, the self-service printer includes a cabinet 50, a printing control device, a printing device 60, and a printer paper feeder. The specific structure of the printer paper feeder is as described in the above embodiments. Since this self-service printer adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0058] The cabinet 50 has a mounting cavity 51, and a paper feed port is located on one side of the cabinet 50, which is connected to the mounting cavity 51. A printing control device is installed in the cabinet 50, and a printing device 60 is installed inside the cabinet 50 and electrically connected to the printing control device. As we know, the printing device 60 is a machine used for printing documents or photos. Since the printing device 60 is a very mature technology and has been widely used in the market, this application will not elaborate further on the technical principles and detailed structure of the printing device 60; for details, please refer to existing technologies.

[0059] The printing device 60 can be a color inkjet printer 60 or a color laser printer 60, etc. Of course, it can also be a regular black and white printer 60. The specific configuration can be set according to actual needs, and this application does not impose any specific restrictions on it.

[0060] The receiving end of the printer paper feeder corresponds to the paper output port 61 of the printing device 60, and the feeding end of the printer paper feeder corresponds to the paper take-up port. Specifically, after the printed paper comes out of the paper output port 61 of the printing device 60, it enters the paper feeding channel 11 of the printer paper feeder through the receiving end of the printer paper feeder. The paper feeding structure 20 then feeds the printed paper from the feeding end of the printer paper feeder to the paper take-up port for the user to pick up.

[0061] In some embodiments, the printing device 60 has a paper output channel and a paper output port 61 communicating with the paper output channel. The receiving end of the printer paper feeder is inserted into the paper output channel, and the outer wall of the printer paper feeder abuts against the channel wall of the paper output channel. Specifically, at least the shape of the receiving end of the printer paper feeder is adapted to the shape of the paper output channel of the printing device 60, so that when the receiving end of the printer paper feeder is inserted into the paper output channel of the printing device 60, the outer wall of the printer paper feeder abuts against the channel wall of the paper output channel of the printing device 60, thereby enabling the printer paper feeder to be inserted and fitted into the paper output channel. In this way, the printer paper feeder can be fixedly installed without the use of any fasteners. Moreover, when it is necessary to remove the printer paper feeder from the printing device 60, it is only necessary to apply a pulling force to the printer paper feeder to pull the receiving end of the printer paper feeder out of the paper output channel, thus improving the ease of installation and removal of the printer paper feeder.

[0062] In some embodiments, the self-service printer further includes a paper storage structure 80, which has a paper storage channel. The receiving end of the paper storage channel corresponds to the output end of the printer's paper feeder, and the output end of the paper storage structure 80 corresponds to the paper dispensing port. Specifically, after the printed paper enters the paper feeding channel 11, it is fed from the output end of the paper feeding channel 11 to the paper storage channel via the paper feeding structure 20, i.e., stored by the paper storage structure 80. After all the documents or photos needed by the user have been printed, the user can retrieve the printed paper from the paper storage channel, thus improving the user experience. Furthermore, in other embodiments, the self-service printer does not have a paper storage structure 80.

[0063] In some embodiments, the self-service printer further includes a baffle 70, which is disposed at the paper feed slot and used to open and close the paper feed slot. That is, the baffle 70 is movably disposed at the paper feed slot for opening and closing the paper feed slot. This arrangement allows the baffle 70 to block rainwater, preventing rainwater from entering the cabinet 50 from the paper feed slot, thereby reducing the risk of water ingress into the paper feed slot. Optionally, the baffle 70 is provided with a gripping part 71 for the user to grip, allowing the user to open the baffle 70 by gripping the gripping part 71, which improves the user experience.

[0064] Furthermore, the self-service printer also includes an electronic lock, which is located in the cabinet 50. The baffle 70 has a lock hole, and the lock tongue of the electronic lock is inserted into the lock hole to fix the baffle 70 in the closed state. The electronic lock is electrically connected to the printing electronic control module, and the electronic control device is used to control the opening and closing of the electronic lock.

[0065] Specifically, users need to unlock the electronic lock before they can open the cover 70. This setting prevents others from opening the cover 70 and taking the printed paper while the user is waiting to print and leaving the self-service printer area.

[0066] The unlocking method of the electronic lock can be selectively set. In one embodiment, the user can unlock it via a mobile phone or on the display screen. It is worth noting that when unlocking via the display screen, a password must be entered first. Of course, in other embodiments, the self-service printer may not have an electronic lock.

[0067] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
