Description

Technical Field

[0001] This utility model relates to the field of ink pressing technology for printers, specifically to an ink bladder-type air bladder ink pressing device for printers. Background Technology

[0002] During inkjet printing, ink is ejected from the printhead in the form of droplets, eventually landing on the corresponding positions on the substrate to form a pre-designed pattern. Due to prolonged use or storage, ink residue at the nozzle orifice can easily clog the printhead, affecting print quality. Therefore, it is necessary to clean and moisturize the printhead regularly.

[0003] The cleaning and moisturizing process generally includes three steps: ink delivery, ink extraction, and wiping. Ink delivery: The ink in the ink cartridge is delivered into the ink sac, and the ink in the ink sac is delivered into the printhead. The purpose is to fully deliver the ink to the printhead's ink orifice. Ink extraction: A pump is used to draw ink outwards at the nozzle, creating pressure to help forcefully extract the ink and air bubbles. Wiping: A rubber scraper is used to wipe the surface of the nozzle plate to remove residual ink stains.

[0004] In related technologies, the aforementioned ink feeding step only involves controlling the extraction of ink from the ink sac by an operating controller, allowing it to flow into the printhead. The entire ink absorption process takes a long time (20 seconds to 1 minute), which affects work efficiency. Utility Model Content

[0005] In view of this, the present invention provides an ink bladder-type airbag ink pressing device for printers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An ink bladder-type airbag ink compression device for a printer, used to compress multiple ink bladders in the printer, the device comprising: Multiple airbags are provided, each airbag is in contact with one of the ink sacs, and the airbags are used to press the ink sacs when inflated; An air pump, which is connected to the airbag via a solenoid valve; The controller includes a timing unit and a control unit, wherein the timing unit is connected to the control unit, and the control unit is connected to the air pump and the solenoid valve respectively; A push-button switch is connected to the control unit; The push-button switch is used to send an inflation command to the control unit when a press command is received, so that the control unit controls the air pump to turn on and the solenoid valve to be energized to inflate the airbag; the timing unit is used to send a deflation command to the control unit when the current time reaches a preset time, so that the control unit controls the push-button switch to pop up, and controls the air pump to turn off and the solenoid valve to be de-energized and closed, so that the airbag deflates.

[0007] A further improvement of this utility model is that the preset time is 0.5 to 1 second.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, in the following description, specific details such as particular system structures and technologies are set forth for illustrative purposes rather than for limiting purposes, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art should understand that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details hindering the description of the present invention.

[0020] This utility model embodiment provides an ink bladder-type airbag ink compression device for a printer, which is used to compress multiple ink bladders 100 in the printer through airbags 8. The number of airbags 8 matches the number of ink bladders 100, and can be specifically determined according to the model and number of printheads. This utility model embodiment does not make specific limitations in this regard.

[0021] like Figures 1-3 As shown, the ink cartridge type airbag ink supply device for a printer includes: Multiple airbags 1 are provided, each airbag 1 contacting one of the ink sacs 100, and the airbag 1 is used to press the ink sac 100 when inflated; each airbag 1 is connected to an air pump 2 and a solenoid valve 3; specifically, as shown... Figure 1 and Figure 2 As shown, it also includes: an airbag mounting bracket, wherein the airbag mounting bracket is provided with multiple side-by-side receiving slots, each receiving slot being provided with an ink sac and an airbag. By placing the ink sac and the airbag in the same receiving slot, when the airbag inflates, the ink sac 100 can be pressed by the obstruction of the side wall of the receiving slot. The controller 4 includes a timing unit and a control unit, wherein the timing unit is connected to the control unit, and the control unit is connected to the air pump 2 and the solenoid valve 3 respectively; The push switch 5 is connected to the timing unit 402 and the control unit 401 respectively; The push-button switch is used to send an open signal to the control unit 401 when it receives a press command (wherein the command is generated by human operation, that is, when a person presses the switch, the press command is generated), so that the control unit 401 controls the air pump 2 to turn on and controls the solenoid valve 3 to be energized and started. At this time, the timing unit 402 starts timing. The timing unit 402 is used to send a close signal to the control unit 401 when it determines that the current time has reached a preset time, so that the control unit 401 controls the push-button switch 5 to pop up, controls the air pump 2 to turn off, and controls the solenoid valve 3 to be de-energized and closed, so that the airbag deflates.

[0022] When ink pressing is required, the operator manually operates the press switch 5. Upon receiving the press command, the press switch 5 sends an inflation command to the control unit 401. The control unit 401 then controls the air pump 2 to open and the solenoid valve 3 to open, thereby inflating the air bag 1 with gas through the air pump 2. The air bag 1 inflates and compresses the ink bag 100, thus achieving ink pressing. At this time, the timing unit 402 starts timing. When it is determined that the current time has reached the preset time (i.e., within 1 second from the start of timing from the press switch 5), it sends an air release command to the control unit 401. The control unit 401 then controls the air pump 2 to close and the solenoid valve 3 to close. This preset time can be set by the operator according to actual needs, and it can be 0.5 to 1 second. This embodiment of the utility model does not specifically limit this.

[0023] In order to realize the functions of the aforementioned controller, in this embodiment of the utility model, the solenoid valve can be set as a two-position three-way solenoid valve, with the first interface connected to the air pump, the second interface connected to the airbag, and the third interface connected to the atmosphere.

[0024] The specific form of the controller 4 in this embodiment is not limited. It can be a time relay, or of course, a microcontroller, etc. It is only necessary to ensure that it can both control the air pump 2 and the solenoid valve 3 and perform timing. For example, it is a time relay.

[0025] The ink cartridge-type airbag 1 ink pressing device for printers provided in this embodiment of the utility model, by setting up an airbag 1, an air pump 2, a solenoid valve 3, a controller 4 including a timing unit 402 and a control unit 401, and a press switch 5, can automatically press ink by pressing the press switch 5 only once, which is convenient, easy to operate and eliminates the possibility of operational errors. In addition, the ink pressing process is visible through the airbag 1, which can greatly shorten the cleaning and moisturizing time (from 20 seconds to 1 minute to less than 1 second), which not only saves ink and time, but also has high flexibility (the number of ink cartridges and airbags 1 can be matched according to different models and quantities of printheads). Furthermore, its structure is simple, easy to install, and low in cost, making it suitable for widespread promotion.

[0026] In addition, the ink cartridge is made of plastic, while the air bag 1 is made of TPU. TPU is a soft material, which ensures that the ink cartridge is subjected to uniform force, and the printhead outputs ink evenly under low pressure, thus extending the life of the printhead and making it more adaptable to different environments.

[0027] Furthermore, to ensure the long-term operation of the aforementioned air pump 2, solenoid valve 3, controller 4, and push switch 5, such as... Figure 2 As shown, it also includes a power module 6, which is connected to the air pump 2, solenoid valve 3, controller 4 and push switch 5 respectively, to supply power to the air pump 2, solenoid valve 3, controller 4 and push switch 5. The voltage of the power module 6 is DC24V, and the rated voltage of the air pump 2 and the solenoid valve 3 is DC24V. The power module 6 can be a storage battery, a lithium battery or an external power interface, and this embodiment of the utility model does not specifically limit it.
