Technical Field
[0001] The utility model relates to the technical field of ink cartridges, and more specifically to a device for non-contact detection of the state of a secondary ink cartridge. Background Art
[0002] As digital inkjet printing is increasingly widely used, industrial printers are also flourishing. In many printing devices, secondary ink cartridges can be found. Their main function is to supply the print head with suitable, stable and continuous ink. However, due to their poor stability, the quality of printing is seriously affected. In addition, with the development of a wide variety of inks, some types of inks have temperature requirements, and some inks have brightness requirements. Most of the secondary ink cartridges in the prior art use contact floats to detect the ink status. Since the processing parts of the installation are all sealed with glue, there are certain problems with the sealing and airtightness of the current contact floats. They are easily affected by the ink temperature and the vibration of the spray car, which can easily cause ink leakage and disconnection. At the same time, since the existing secondary ink cartridges can only detect whether there is ink and whether the ink is full, if there is a lack of ink during the printing process, the printing must be suspended while waiting for the ink to be drawn. This situation is not allowed in some cases and cannot achieve early warning. Therefore, in response to the above technical defects, the utility model provides a device for non-contact detection of the status of the secondary ink cartridge to solve the above problems.

[0029] The drawings of the present invention are only used for illustrative purposes and cannot be construed as limiting the present invention. In order to better illustrate the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.
[0030] Example 1
[0031] like Figure 1As shown, Figure 1 The exploded schematic diagram of the structure of the device is shown in FIG. 1 . The present embodiment provides a device for non-contact detection of the status of a secondary ink cartridge, including:
[0032] A float 1 for monitoring the ink level inside the ink cartridge, a fixed structure for limiting the movement trajectory of the float, and a display panel 2 for displaying the current ink status of the ink cartridge; wherein, Figure 2 and Figure 3 As shown, the float 1 is defined on a fixed structure and arranged inside the ink cartridge, and the display panel 2 is arranged on the ink cartridge and is on the same horizontal line as the movement trajectory of the float 1;
[0033] Preferably, if Figure 4 As shown, Figure 4 This is a top view of the internal structure of this embodiment, from Figure 4 It can be seen that the display panel 1 is provided with a plurality of indicator lights 3 and a magnetic induction component, and the magnetic induction component is non-contactly connected with the float 1 to control the status of different indicator lights, thereby detecting the current ink status and issuing an early warning.
[0034] In this device, the float 1 will float up and down as the content of ink in the ink cartridge changes. Then, by setting a magnetic induction component on the display panel to connect to the float 1 in a non-contact manner, the indicator light 3 on the display panel 2 is turned on or off, and the real-time status of the ink in the ink cartridge can be intuitively obtained, which is convenient for monitoring the ink cartridge and preventing problems during the printing process. It can also solve the problem of poor sealing and airtightness of the ink cartridge caused by the use of a contact float in the prior art, which makes the ink easily leak and break due to the influence of temperature and vibration of the spraying vehicle.
[0035] Preferably, the middle part of the float 1 is made of floatable material, and the two ends are made of ferrite material, which is connected to the magnetic induction component by magnetic induction contactless method to control the brightness of the indicator light 3 to detect the current ink status.
[0036] In this embodiment, the material used for the middle part of the float 1 should be buoyant, compatible with ink and have good corrosion resistance. Optionally, it can be made of plastic materials, such as polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), etc. These plastics usually have good chemical corrosion resistance and stability, and are suitable for contact with ink. In addition, they also have good processability, and can be manufactured into floats of various shapes and sizes by injection molding and other methods to adapt to different types of ink cartridge designs. It is also a relatively economical material that can meet the cost budget requirements of most ink cartridge manufacturing. It also has good mechanical properties, such as strength and rigidity. These properties are also very important for the stability and durability of the float 1, and will not affect the non-contact connection between the float 1 and the magnetic induction component, and is not limited to the use of the above-mentioned materials for manufacturing; and the two ends of the float 1 are made of ferrite material, the purpose of which is to enable the float 1 to generate magnetic induction with the magnetic induction component, thereby achieving non-contact connection and ensuring the accuracy of real-time ink status detection.
[0037] The middle part and the two end parts of the float 1 are made of two different materials, which ensures that the float 1 can float on the ink liquid surface and can also generate magnetic induction with the magnetic induction component, thereby realizing non-contact connection.
[0038] Preferably, from Figure 1 It can be seen from the figure that the plurality of indicator lights 3 are evenly distributed on the display panel 2 according to the set intervals.
[0039] In this embodiment, the position of the indicator light 3 on the display board 2 can be set according to the size of the ink cartridge. The number of the indicator lights 3 is set to 5 and evenly distributed on the display board 2 according to the set spacing, which are light 01, light 02, light 03, light 04, and light 04. As the amount of ink in the ink cartridge changes, the float 1 is non-contactly connected with the indicator lights 3 on the display board 2 to control the brightness of the indicator lights. When only light 01 is on, it means that the ink cartridge is at the full ink level; when light 02 is on or light 01 and light 02 are on, it means that the ink cartridge is at the ink level; when light 03 is on or light 02, light 03 is on or light 03 and light 04 are on, it means that the ink cartridge is at the normal level; when light 02 is on or light 04 and light 05 are on, it means that the ink cartridge is at the low ink level; when only light 05 is on, it means that the ink cartridge is at the ink level. Therefore, the ink volume of the ink cartridge can be divided into 5 different levels through the brightness changes of the above different indicator lights 3.
[0040] More preferably, if Figure 2As shown, in this embodiment, the display panel 2 is also provided with a communication interface, which can be used to transmit ink status information, and transmit the ink level information displayed by the indicator light 3 to the control system, so that the staff can understand the ink status in real time, wherein, when the received ink level information is full of ink or no ink, the alarm state is displayed; when the received ink level information is too much ink or too little ink, the warning state is displayed; when the received ink level information is normal, the normal state is displayed;
[0041] In addition, if there are other abnormal conditions besides the above-mentioned ink conditions, it means that there are other abnormal conditions that may be caused by failure of device components. For example, if none of the indicator lights 3 are on, three indicator lights 3 are on together, or the cross indicator light 3 is on, etc., these are all abnormal conditions and the device needs to be repaired in time. Among them, when none of the indicator lights 3 are on, it is necessary to check whether the position settings of the power supply and the magnetic induction component are incorrect, resulting in a lack of connectivity; secondly, if the three indicator lights 3 are on together, it is necessary to check whether there is an abnormality in the magnetic induction. When the cross indicator light 3 is on, it is necessary to check whether the abnormal situation is caused by unreasonable setting of the indicator light position or failure of the magnetic induction component.
[0042] Therefore, the ink status of the secondary ink cartridge is divided into 5 levels and four states through the brightness of the real-time status indicator light, including normal state, warning state, alarm state and abnormal state, so that the status of the ink in the current ink cartridge can be intuitively understood, and if a warning or abnormal situation occurs, it can be dealt with in time.
[0043] Preferably, if Figure 1-4 As shown, the fixed structure includes a fixed plate 4, a positioning plate 5 and a limiting seat 6; the positioning plate 5 is a long hollow structure, and the limiting seat 6 is a slide rail structure; the fixed plate 4, the positioning plate 5 and the limiting seat 6 are on the same horizontal line, which are used to limit the movement trajectory of the float 1.
[0044] By setting the above-mentioned fixed structure, the movement trajectory of the float 1 can be limited to be consistent with the arrangement of the indicator light 3, which can ensure the accuracy of the indicator light 3 in displaying the ink status.
[0045] Preferably, from Figure 1 As can be seen from the figure, buckle structures 7 are provided at both ends of the clamping plate 5. Figure 2 As shown, the buckle structure 7 abuts against the inside of the ink cartridge.
[0046] Preferably, the fixing plate 4 is provided with a mortise 8, and the mortise 8 cooperates with a tenon 9 inside the ink cartridge.
[0047] By adopting the above-mentioned movable connection method, when the ink cartridge is detected to be in an abnormal state, it is convenient to disassemble, repair and replace the ink cartridge.
[0048] Preferably, if Figure 4 As shown, the float 1 is a cylindrical strip-shaped structure with a concave middle portion, and the concave middle portion is limited to the long hollow structure of the positioning plate 5; one end of the float 1 is nested in the limiting seat 6, as shown in FIG. Figure 3 As shown, the other end is close to the display panel 2 and is defined by the fixing plate 4.
[0049] By limiting the middle part and both ends of the float 1, the float 1 will not float and sway left and right, ensuring the stability of the float 1 moving with the ink content and improving the stability of the real-time state detection of the ink.
[0050] Preferably, the comprehensive density ρ of the float 1 is ≤0.8 g / ml.
[0051] Preferably, the magnetic flux Φ of the float 1 is greater than 200 Gs.
[0052] In this embodiment, the comprehensive density of the float 1 is set to ensure that the float 1 floats on the surface of the ink and accurately determines the liquid level of the ink, thereby monitoring the ink status in real time; in addition, the magnetic flux Φ of the float 1 is set to >200Gs to ensure that the float 1 can be magnetically induced by the magnetic induction component on the display panel 2 to achieve non-contact connection, thereby turning on the indicator light 3 to monitor the ink status in real time.
[0053] Obviously, the above embodiments of the utility model are only examples for clearly explaining the technical solution of the utility model, and are not intended to limit the specific implementation methods of the utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the claims of the utility model shall be included in the protection scope of the claims of the utility model.
