Description

Technical Field

[0001] The utility model relates to the technical field of thermal transfer printing, specifically to the technical field of a printer ink cartridge device. Background Art

[0002] Traditional thermal transfer printer ink cartridges have problems in replacement or ink replenishment. The ink cartridges are usually fixed inside the printer. When replacing or replenishing ink, it is necessary to stop the machine and disassemble multiple components. The operation is complex and time-consuming, increasing the maintenance difficulty for users.

[0003] This is mainly a problem caused by the characteristics of thermal transfer printers. Conventional inkjet printing usually sprays directly from the ink cartridge onto the printing medium, with low requirements for the fluidity of the ink, and is easy to replace. The impact of the replacement operation on the printing quality is relatively small.

[0004] While thermal transfer printers usually transport ink from the ink cartridge to the print head through a pipeline, it is necessary to ensure the smooth flow of the ink. Therefore, it is necessary to always maintain a sufficient amount of ink. Summary of the Utility Model

[0005] To solve the above problems, in view of the deficiencies of the prior art, the utility model provides a printer ink cartridge device, aiming to ensure that users can quickly replace the ink cartridge or replenish ink by optimizing the design and installation method of the ink cartridge.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0024] The features of the present invention and other related features are further described in detail below through embodiments for the understanding of those skilled in the same industry:

[0025] The present invention is further described in detail below with reference to the drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "bottom surface" and "top surface", "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component, respectively.

[0026] Please refer to Figures 1 to 3, a printer cartridge device in this case is a cartridge device applied to a thermal transfer printer. Different from an inkjet printer, a thermal transfer printer needs to always maintain sufficient ink volume to ensure the smooth flow of ink. The printing device is provided with a print head that moves in the left - right direction inside the printer. The way of supplying ink to the print head can be a pipeline connection method. The ink cartridge is directly connected to the print head through a pipeline, and the ink is continuously supplied to the print head through the pipeline. Another way is to set an ink cartridge station at the right - hand side of the printer. When the print head needs to be replenished with ink, it returns to this position. No matter which way of supplying ink is used, sufficient ink volume needs to be maintained.

[0027] In response to this, a printer cartridge device in this case includes a detachable ink cartridge box 100 provided at the rear end of the printer, and a plurality of refillable ink cartridges 200 are provided inside the ink cartridge box 100. The number of ink cartridges 200 is set according to requirements. In specific applications, it is generally distinguished between white ink cartridges and color ink cartridges. Among them, the color ink cartridges can be yellow, red, blue, and black. It also includes a box cover 300 that is openably connected to the ink cartridge box 100 and covers the ink cartridges 200. The box cover 300 and the ink cartridge box 100 can be connected by a hinge structure, which is convenient for operation and maintenance.

[0028] Combined with reference to Figure 6 , the ink cartridge 200 is provided with a gooseneck ink - pouring port 210 that can be refilled midway. A refill hole 310 is provided at the gooseneck ink - pouring port 210 on the box cover 300, so that after the box cover 300 is closed, the gooseneck ink - pouring port 210 is still exposed. An observation hole 110 is provided in the ink cartridge box 100 for observing the remaining amount of ink in the ink cartridge 200.

[0029] In this way, when implementing a printing operation, there is no need to perform the operation of stopping the machine and disassembling. Through observing the ink remaining amount, the ink cartridge 200 can be directly refilled in the ink cartridge box 100 provided at the rear end of the printer.

[0030] Please continue to refer to Figure 6 , there is a potential hazard of human misjudgment when observing through the observation hole 110. For this reason, an ink - shortage sensing device 220 is provided in the ink cartridge. The ink - supply device 230 is arranged at the upper part. At this time, the box cover 300 can cover the ink - shortage sensing device 220 and the ink - supply device 230, while exposing the gooseneck ink - pouring port 210, which can not only facilitate ink replenishment but also play an effective protective role. A ink - path circulator 231 is also provided, which helps to ensure the smooth flow of ink between the ink cartridge 200 and the print head, and removes the air in the system to prevent the formation of air bubbles and ensure the printing quality.

[0031] Preferably, the ink shortage sensing device 220 is a float sensor. A float is installed inside the ink cartridge, and the float moves as the height of the ink liquid level changes. A magnet is installed on the float. When the ink is insufficient, the float descends, and the magnet approaches the magnetic switch, triggering an ink shortage signal. The float sensor has the advantages of simple structure, high reliability, and relatively low manufacturing cost.

[0032] During specific implementation, the ink shortage sensing device 220 can be directly connected to the printer control device and overall controlled by the printer control system. However, for its independence and fault tolerance, it is preferably to set up an independent ink shortage alarm device in the ink cartridge. The specific implementation method can be that the ink shortage alarm device is provided with a control board 241, and an independently powered battery 242, which can be a button battery, is installed on the control board 241. It is connected to the ink shortage sensing device 220 through the information interface 243 to obtain the ink shortage signal. It also includes an alarm buzzer 245 that emits a beeping sound and an alarm light 244 for light indication according to the ink shortage signal. The ink shortage alarm device can also be provided with an alarm control switch 246.

[0033] As described above, the ink cartridge 200 is divided into a white ink cartridge and a color ink cartridge, and at least one is a white ink cartridge. Since the viscosity of white ink is usually relatively high to ensure that pigment particles can be evenly distributed to form a uniform coating. If not stirred, problems such as uneven color and reduced covering power may occur during printing. For this reason, at least one stirring motor hole 320 is provided on the white ink cartridge, that is, on the box cover 300, and a stirring motor 400 is provided for stirring.

[0034] Please refer to Figure 4 and Figure 5 , the printer ink cartridge device in this case needs to transport ink to the print head, that is, it is connected to the inner cavity of the printer by a pipeline. For this reason, the entire ink cartridge box 100 has a need for easy disassembly and assembly. In this regard, the ink cartridge box 100 is fixed to the printer through an anti-detachment bolt structure. The specific implementation method is that the anti-detachment bolt structure is a gourd-shaped hanging hole 120. Without fully unscrewing the bolt, the ink cartridge box 100 can be disassembled and adjusted while still hanging on the gourd-shaped hanging hole 120.

[0035] In some embodiments of this case, a waste ink box 500 for placing the replaced waste ink cartridges is provided at the bottom of the ink cartridge box 100.

[0036] As described above, what this case protects is a printer ink cartridge device, and all technical solutions identical or similar to this case should be regarded as falling within the protection scope of this case.
