Description

Technical Field

[0001] This utility model relates to the field of printer cleaning technology, specifically a printer nozzle cleaning device. Background Technology

[0002] A printer is a computer output device used to print computer-processed results onto relevant media. Three key indicators of printer quality are print resolution, print speed, and noise level. There are many types of printers. Based on whether the printing element strikes the paper, they are divided into impact printers and non-impact printers. Based on the structure of the printed characters, they are divided into full-character printers and dot-matrix character printers. Based on how a line of text is formed on the paper, they are divided into serial printers and line printers. Based on the technology used, they are divided into column printers, ball printers, inkjet printers, thermal printers, laser printers, electrostatic printers, magnetic printers, and LED printers. After a period of use, inkjet printers may experience problems such as unclear printing, broken lines in text, blank pages, missing black content, missing color content, hollow text, incorrect pattern colors, missing parts of content, and white lines or horizontal lines in the image. These problems are often caused by the printer not being used for a period of time or having a low printing frequency, so the printhead needs to be cleaned.

[0003] Chinese Utility Model Patent Publication No. CN 216268224 U discloses a printhead cleaning device for an inkjet printer. This device adds cleaning fluid during the rinsing of the printhead, which not only reduces ink adhesion but also improves the cleaning efficiency. Using cleaning fluid reduces the need for disassembling and reassembling the printhead, improving cleaning efficiency while avoiding damage to the printhead from manual contact. However, this printhead cleaning device needs to be integrated into the printer, resulting in a large overall footprint. Furthermore, the printhead needs to be removed for cleaning, requiring disassembly and reassembly, which reduces its practicality and hinders its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a printer nozzle cleaning device that can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a printer nozzle cleaning device, including a printing table, a first workbench and a second workbench fixedly installed on both sides of the printing table, a translation mechanism for moving the printer fixedly installed at one end of the printing table located on the table surface, a printing box and a print nozzle provided at the end of the translation mechanism away from the printing table, a cleaning component and a heater provided inside the printing table, an air duct opened inside the printing table, and a blower fixedly installed at the other end of the air duct away from the printing table;

[0006] The cleaning component includes a cylinder located inside the printing table. A water reservoir that is slidably connected to the printing table is fixedly installed on the output shaft of the cylinder. The end of the water reservoir near the cylinder is provided with a solenoid valve for draining and inlet water, a connecting pipe, and a water tank made of transparent material located inside the printing table. A water storage tank is provided at the end of the water reservoir away from the water tank.

[0007] Preferably, a positioning column for positioning is fixedly installed inside the water storage tank, and a partition plate is provided inside the water storage tank, the partition plate being adapted to the positioning column.

[0008] Through the above technical solution, by designing the positioning column, when cleaning the printhead, the appropriate partition plate can be selected according to the number of printheads. Then, with the positioning column, the partition plate can be limited, which makes it easier to clean a single printhead.

[0009] Preferably, there are two identical solenoid valves, connecting pipes, and water tanks, and both solenoid valves, connecting pipes, and water tanks are interconnected with the water storage tank.

[0010] Through the above technical solution, the two sets of solenoid valves, connecting pipes, and water tank are interconnected with the water storage tank, which facilitates the water intake and drainage of the water storage tank. In use, hot or cold water can be placed inside the water storage tank, and then the water is moved to the top of the cleaning component by the translation mechanism. Then the cylinder pushes the water storage bar to move up and down, so that the print head is located in the water storage tank. The solidified ink can be soaked or ultrasonically cleaned, which can facilitate the quick cleaning of the print head and improve its cleaning efficiency.

[0011] Preferably, the printing table has a groove 1, a groove 2 and a through groove at one end near the cleaning component, and the groove 2 is slidably connected to the cleaning component.

[0012] Through the above technical solution, the design of the first groove allows a cover plate to be placed inside the first groove when not in use, which can prevent dust from falling into the interior of the cleaning component. Furthermore, the design of the second groove facilitates the up-and-down movement of the cleaning component, which can serve as a guide and improve the overall stability.

[0013] Preferably, the printing table has a slot on the side near the heater and on the table surface, and a through plate is provided inside the slot.

[0014] The above technical solution, through the design of the card slot, facilitates the quick placement of the printing plate, and the design of the printing plate can prevent dust from falling into the interior of the printing table, thus improving its practicality.

[0015] Preferably, a guide plate is fixedly installed at the other end of the printing table located in the air duct and away from the blower, and the side of the guide plate near the heater is designed to be inclined.

[0016] Through the above technical solution, the inclined design of the guide plate cleverly changes the flow direction of hot air in the air duct, so that the hot air blown out by the blower can be blown more concentratedly and efficiently towards the vicinity of the heater. After the water washing is completed, the print head can be moved above the through plate and then air-dried and heated to ensure that the print head and related components can be dried quickly, effectively reducing print head clogging caused by moisture.

[0017] Preferably, the heater is located on both sides of the heater, the heater is located at one end of the through plate near the printing table, and a maintenance plate is provided on the back of the printing table.

[0018] Through the above technical solution, the heater can be turned on before the fan starts, which can improve the drying efficiency during the drying process. Furthermore, the inspection panel is located on the back of the printing table, allowing staff to easily inspect, repair, and replace the heater and other internal components of the printing table simply by opening the inspection panel.

[0020] 1. The printer's printhead cleaning device, with its solenoid valve, connecting pipe, and water tank interconnected with the water storage tank, facilitates water intake and drainage. During use, hot or cold water can be placed inside the water storage tank, and then moved above the cleaning component via a translation mechanism. Subsequently, a cylinder pushes the water storage bar up and down, positioning the printhead in the water storage tank. This allows for soaking of solidified ink or ultrasonic cleaning, facilitating rapid cleaning of the printhead and improving its cleaning efficiency.

[0021] 2. The printer's printhead cleaning device features a cleverly designed inclined guide plate that alters the flow direction of hot air within the air duct. This allows the hot air blown by the blower to be directed more concentratedly and efficiently towards the vicinity of the heater. After the water washing is complete, the printhead can be moved above the through plate for subsequent air drying and heating, ensuring that the printhead and related components can dry quickly and effectively reducing printhead clogging caused by moisture.

[0022] 3. The printer's printhead cleaning device is integrated into the printer, which reduces the overall footprint of the device and eliminates the need to remove the printhead for cleaning, thereby improving the practicality of the cleaning component and facilitating its widespread use.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: As Figure 1-8As shown, the present invention provides a printer nozzle cleaning device, including a printing table 1, a first workbench 2 and a second workbench 3 fixedly installed on both sides of the printing table 1, a translation mechanism 4 for moving the printer fixedly installed at one end of the printing table 1 located on the table surface, a printing box 5 and a print nozzle 6 provided at the end of the translation mechanism 4 away from the printing table 1, a cleaning component 11 and a heater 16 provided inside the printing table 1, an air duct 12 opened inside the printing table 1, and a blower 13 fixedly installed at the other end of the air duct 12 away from the printing table 1.

[0034] The cleaning component 11 includes a cylinder 1101 located inside the print station 1. A water reservoir 1102, which is slidably connected to the print station 1, is fixedly installed on the output shaft of the cylinder 1101. The end of the water reservoir 1102 near the cylinder 1101 is provided with a solenoid valve 1103 for draining and water entering, a connecting pipe 1104, and a water tank 1105 made of transparent material located inside the print station 1. A water storage tank 1106 is provided at the end of the water reservoir 1102 away from the water tank 1105.

[0035] Specifically, a positioning post 1107 for positioning is fixedly installed inside the water storage tank 1106, and a partition plate 1108 is provided inside the water storage tank 1106. The partition plate 1108 is adapted to the positioning post 1107. The advantage is that, through the design of the positioning post 1107, when cleaning the print head 6, the appropriate partition plate 1108 can be selected according to the number of print heads 6. Then, in conjunction with the positioning post 1107, the partition plate 1108 can be limited, which makes it easier to clean a single print head.

[0036] Specifically, two identical solenoid valves 1103, connecting pipes 1104, and water tanks 1105 are provided. Both solenoid valves 1103, connecting pipes 1104, and water tanks 1105 are interconnected with the water storage tank 1106. The advantage is that the interconnection of the two sets of solenoid valves 1103, connecting pipes 1104, and water tanks 1105 with the water storage tank 1106 facilitates the filling and draining of water into the water storage tank 1106. In use, hot or cold water can be placed inside the water storage tank 1106, and then moved above the cleaning component 11 by the translation mechanism 4. Subsequently, the cylinder 1101 pushes the water storage bar 1102 to move up and down, thereby placing the print head 6 in the water storage tank 1106. The solidified ink can be soaked or ultrasonically cleaned, which facilitates quick cleaning of the print head and improves its cleaning efficiency.

[0037] Specifically, the printing table 1 has a groove 7, a groove 8 and a through groove 9 at one end near the cleaning component 11. The groove 8 is slidably connected to the cleaning component 11. The advantage is that, through the design of the groove 7, when not in use, a cover plate can be placed on the inside of the groove 7 to prevent dust from falling into the interior of the cleaning component 11. In addition, the design of the groove 8 facilitates the up and down movement of the cleaning component 11, which can play a guiding role and improve the overall stability.

[0038] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0039] Specifically, a slot 14 is provided on the side of the printing table 1 near the heater 16 and on the table surface of the printing table 1. A through plate 15 is provided inside the slot 14. The advantage is that the design of the slot 14 makes it easy to quickly place the through plate 15, and the design of the through plate 15 can prevent dust from falling into the interior of the printing table 1, thus improving its practicality.

[0040] Specifically, a guide plate 17 is fixedly installed at the other end of the printing table 1 located in the air duct 12 and away from the blower 13. The side of the guide plate 17 near the heater 16 is designed with an inclination. The advantage is that the inclination design of the guide plate 17 cleverly changes the flow direction of the hot air in the air duct 12, so that the hot air blown out by the blower 13 can be blown more concentratedly and efficiently towards the vicinity of the heater 16. After the water washing is completed, the print head 6 can be moved above the through plate 15 and then air-dried and heated to ensure that the print head 6 and related components can be dried quickly, effectively reducing print head clogging caused by moisture.

[0041] Specifically, heaters 16 are located on both sides of the printing plate 15 near the printing table 1. A maintenance plate 10 is provided on the back of the printing table 1. The advantage is that the design of heaters 16 allows them to be turned on before the blower 13 is started, which improves the drying efficiency during drying. Furthermore, the maintenance plate 10 is located on the back of the printing table 1, allowing staff to easily inspect, repair, and replace heaters 16 and other internal components of the printing table 1 simply by opening the maintenance plate 10.

[0042] Working principle: When cleaning the printhead 6 is required, select the appropriate partition plate 1108 according to the number of printheads and install it in conjunction with the positioning post 1107 in the water tank 1106 to achieve targeted cleaning of individual printheads. Two sets of solenoid valves 1103, connecting pipes 1104, and water tank 1105 are interconnected with the water tank 1106, allowing hot or cold water to be injected into the water tank. The translation mechanism 4 moves the printhead 6 above the cleaning component 11. The cylinder 1101 pushes the water reservoir 1102 up and down, immersing the printhead in the water tank 1106 to soak the solidified ink or clean it with ultrasonic waves, quickly removing dirt from the printhead and improving cleaning efficiency. The groove 7 at the end of the printing table 1 near the cleaning component 11 can be covered when the device is not in use to prevent dust from falling into the cleaning component 11. The second groove 8 is for cleaning... The up-and-down movement of component 11 provides guidance, ensuring smooth movement and improving overall stability. After washing, the translation mechanism 4 moves the print head 6 above the through plate 15. The guide plate 17 at the air duct 12 inside the print table 1 is designed with an inclination, which can change the direction of the hot air blown out by the blower 13, making it blow more concentrated near the heater 16. Before the blower 13 is started, the heater 16 is turned on first to increase the temperature of the hot air during the drying process, accelerate the drying speed of the print head 6 and related components, and prevent the print head from being blocked due to moisture. The slot 14 on the surface of the print table 1 facilitates the quick installation and removal of the through plate 15. The through plate 15 prevents dust from entering the interior of the print table 1. The back of the print table 1 is equipped with a maintenance plate 10. When the staff opens the maintenance plate 10, they can inspect, repair and replace the heater 16 and other components inside the print table 1, reducing the difficulty of maintenance.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
