Description

副墨盒,供墨系统及喷墨打印装置 Sub tank, an ink supply system and ink jet printing apparatus

技术领域 FIELD

[0001] 本发明涉及一种副墨盒,具体说涉及一种集成度较高的喷墨打印机副墨盒及使用该副墨盒的供墨系统,及包括含有该副墨盒的供墨系统的喷墨打印装置。 [0001] The present invention relates to a sub tank, particularly relates to an integrated high degree sub tank and an ink jet printer using the ink cartridge of the ink supply sub-system, and ink jet ink supply system including the sub print cartridge comprising device.

背景技术 Background technique

[0002] 近年来由于喷墨打印具有较高的打印速度和优良的图像分辨率,且喷墨打印设备与计算机相结合使用使得最终图像的设计和编排方面的灵活性较大,使得喷墨打印技术的普及程度越来越尚。 [0002] In recent years, since the ink jet printing having high printing speed and excellent image resolution, and ink-jet printing apparatus used in conjunction with the computer so that the flexibility in the design and layout aspect of the final image is large, so that the ink jet printing popularity is still growing technologies.

[0003] 喷墨打印机的喷头小车上安装有多个如图1所示的副墨盒,各种颜色的墨水通过墨路管道从各主墨盒供给各副墨盒,再由各副墨盒将墨水供给各嗔头;副墨盒包括墨盒体01和墨盒盖02,为了保证墨水的可靠供给,副墨盒上设置有液位传感器03,利用该液位传感器03对墨腔中的墨水量进行检测,以便在缺墨时自动加墨,在墨盒体01的下端设置一出墨口04用于向喷头供墨,墨盒体01和墨盒盖02通过四角的螺钉05连接。 [0003] The ink jet printer head carriage mounted with a plurality of the sub tank illustrated in FIG. 1, various colors of ink supplied to each sub tank from the main tank through the ink passage of each pipe, and then by the ink supplied to each sub tank angry head; the sub tank 01 comprises a cartridge body and cartridge cap 02, in order to ensure a reliable supply of ink is provided on the sub tank 03 has a liquid level sensor, a level sensor 03 with which the amount of ink to the ink chamber is detected so that missing automatic ink cartridge body 01 at the lower end is provided an outlet 04 for the ink supply ink to the head, the ink cartridge 01 and the cartridge cover body 02 connected by screws 05 to the four corners when the ink.

[0004] 现有喷墨打印机上副墨盒的安装高度通常高于喷头,受重力影响,墨水可自然地从副墨盒流入喷头。 [0004] The conventional ink jet printer cartridge is mounted on the sub usually higher than the height of the head, by gravity, the ink can naturally flow into the sub tank from the nozzle. 但是,为实现更快的打印速度,现有喷头研发和制造技术水平不断改进,针对工业化喷墨打印用途的喷头的点火频率越来越快,为了保证在高打印速度下的优秀的打印质量,要求打印机根据打印需要持续、稳定、快速、适量地向喷头供墨。 However, to achieve faster print speeds, head existing R & D and manufacturing technology continues to improve, the firing frequency of use for industrial ink jet print head faster and faster, in order to ensure excellent print quality at high printing speed, It requires the printer to print according to need sustained, steady and rapid, the amount of the ink to the head. 现有技术中多采用负压供墨系统,如果负压太低,墨水在重力的作用下连续往下流,供墨过量致使喷头出现滴墨现象;如果负压太尚,嗔头内墨水回流,副墨盒中的墨水不能及时、适量地流向嗔头,导致喷头无墨可喷,出现断墨,影响打印质量。 The prior art in the use of a negative pressure ink supply system, if the negative pressure is too low, a continuous ink flow down under gravity, causing excess ink nozzles of the ink droplet phenomenon occurs; if a negative pressure is still too much, the ink head at reflux anger, sub ink cartridge can not be timely, appropriate amount of flow of anger head, resulting in no ink nozzle can be sprayed, off Mexico, affect print quality.

[0005] 如图2所示,现有技术中供墨系统管路复杂,对于单色打印负压系统主要包括一个副墨盒M1、四个电磁阀Fl、F2、F3、F4,负压传感器S1、负压腔Q、负压栗P1、正压栗P2、压力表S2、气路管、放气阀Π、f2、喷头Hl及控制电路等。 [0005] As shown, the prior art ink complex piping system 2, the negative pressure for monochrome printing system includes a sub tank M1, four solenoid valves Fl, F2, F3, F4, negative pressure sensor S1 , the negative pressure chamber Q, Li negative pressure P1, pressure P2 Li, S2 gauge, the gas passage pipe, the purge valve Π, f2, head Hl and a control circuit. 根据负压传感器SI反馈的负压值控制电路通过控制电磁阀Fl、F2和负压栗Pl的工作维持管路中负压的稳定。 The vacuum sensor value of the negative feedback control circuit SI by controlling the electromagnetic valve Fl, F2 negative Li Pl and work to maintain the stability of the negative pressure line. 喷墨打印过程中,随小车来回震荡导致各管接头松脱、负压系统管路老化、负压系统的气路管接头漏气、负压栗不能正常工作以及放气阀故障等因素都将使负压不稳定,墨水从喷头溢出,导致喷头无法进行正常打印,电磁阀和负压栗频繁通断电,使用寿命减短。 Ink-jet printing process, with the car oscillates back and forth leading to the loose fittings, vacuum piping system aging, gas leak joint pipe negative pressure system, vacuum Li does not work and a purge valve failure factors will the negative pressure is unstable, the ink overflow from the nozzle, the nozzle can not result in normal printing, a solenoid valve and a negative pressure through frequent off Li, shortened service life. 对于打印色数越多的喷墨打印机,其负压系统的管接头数量越多,气路管越长,检测难度更大。 For the more the number of printed color ink-jet printer, the greater the number of the pipe fitting which negative pressure system, the longer the gas passage pipe, more difficult to detect. 六色打印负压系统存在50个接头,25段管路。 The presence of six-color printing system vacuum connectors 50, 25 of the conduit. 一旦漏气,其出问题的可能之处很多,且由于气路漏气的不可见性,更增加了其检测难度。 Once the leak, which could place a lot of problems, and because the gas line leak invisibility, adds to the difficulty of its detection.
