Description

Technical Field

[0001] This utility model relates to the field of printers, specifically to a UV printing ink metering device. Background Technology

[0002] A UV printer is a high-tech, plate-free, full-color digital printer. Its core features include wear resistance, UV protection, high speed, and wide application range, unrestricted by materials. UV printers use UV ink, which is cured instantly by ultraviolet light during printing, resulting in high-quality, durable prints on various materials. UV printers use multiple ink cartridges of different colors, and a special UV printing ink metering device is required to add ink to the cartridges in precise quantities.

[0003] Existing UV printing ink metering devices typically use syringes to add ink to the ink cartridges, and the ink level needs to be constantly monitored during the process to prevent overfilling and leakage.

[0004] If the ink cartridge is accidentally knocked over during the refilling process, a large area of ​​ink will leak because the ink filling port is open during refilling. In addition, the syringe needs to be inserted into the ink filling port during the refilling process, which may cause the outer wall of the syringe to become contaminated due to contact with the ink filling port. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing UV printing ink metering devices cannot determine the liquid level height while ensuring sealing during ink addition.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a UV printing ink quantitative ink supply device, including an ink cartridge, an ink syringe for ink filling is provided on one side of the ink filling port of the ink cartridge, a leak-proof cover is fitted on the ink filling port of the ink cartridge, and an ink filling needle rod connected to the syringe is provided inside the leak-proof cover. A buoyancy rod is provided inside the ink filling needle rod, and a buoyancy ball for detecting the liquid level is provided at the top of the buoyancy rod. An L-shaped probe rod that passes through the ink filling needle rod is attached to one side of the buoyancy rod.

[0007] The bottom of the leak-proof cover is equipped with a pressure sensor located on the top path of the L-shaped detection rod, and a signal light is provided on one side of the pressure sensor to receive the pressure sensor signal. A storage slot for the signal light fixing plate and the pressure sensor is provided on the top of the bottom of the leak-proof cover, and an ink-proof gasket is attached to the pressure sensor detection hole on the bottom of the leak-proof cover.

[0008] As an improvement, the side of the ink-filling needle rod is provided with a limiting groove to restrict the movement direction of the L-shaped probe rod.

[0009] As an improvement, the storage slot is connected to the signal light fixing plate, as well as the ink-proof gasket and the leak-proof cover, by means of waterproof adhesive.

[0010] As an improvement, the ink cartridge has an outlet on the lower side.

[0011] As an improvement, the outer end of the ink filling port of the ink cartridge has a threaded structure, and the outer wall of the ink filling port of the ink cartridge is connected to the leak-proof cover by a sealing gasket.

[0012] As an improvement, the buoyancy rod is connected to the buoyancy ball via a threaded structure.

[0013] The advantages of this invention compared to the prior art are as follows: This device uses a leak-proof cover to ensure that there will be no large-area leakage when adding ink, and the leak-proof cover has an ink-filling needle rod that matches the syringe, which facilitates the stable connection of the syringe. The liquid level is determined by the buoyancy rod and buoyancy ball at the top of the ink-filling needle rod, and the L-shaped probe on one side of the buoyancy rod contacts the pressure sensor on the bottom surface of the leak-proof cover. The liquid level is determined by the pressure change of the pressure sensor, and the liquid level is displayed by an indicator light. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] As per the instruction manual Figure 1 , 2As shown in Figures 3 and 4, the ink cartridge 1 has an ink inlet with an ink cap at the top and an ink outlet 11 at the bottom for discharging ink. A syringe 2 for adding ink is provided on one side of the ink inlet of the ink cartridge 1. In order to ensure that there is no ink leakage and to maintain the liquid level, a leak-proof cap 3 is fitted on the ink inlet of the ink cartridge 1. The outer end of the ink inlet of the ink cartridge 1 has a threaded structure, and the outer wall of the ink inlet of the ink cartridge 1 is connected to the leak-proof cap 3 by a sealing gasket, which is usually made of rubber.

[0021] The leak-proof cover 3 has an ink-filling needle rod 31 connected to the syringe 2 inside. The ink-filling needle rod 31 has a buoyancy rod 32 inserted inside it, and the top of the buoyancy rod 32 has a buoyancy ball 33 for detecting the liquid level. The liquid level of the ink is detected by the buoyancy ball 33 and the buoyancy rod 32. In order to detect the position when the liquid level is full, an L-shaped probe 34 that passes through the ink-filling needle rod 31 is attached to one side of the buoyancy rod 32. In order to ensure the stability of the connection, the L-shaped probe 34 passes through the side wall of the buoyancy rod 32 and is glued with waterproof adhesive. In order to restrict the movement direction of the L-shaped probe 34, a limiting groove 35 is provided on the side of the ink-filling needle rod 31 to restrict the movement direction of the L-shaped probe 34. The limiting groove 35 can also be used as an injection port to increase the flow rate during injection.

[0022] To detect when the buoyancy ball 33 has reached the required level, the L-shaped probe 34 can transmit a full signal. Inside the bottom of the leak-proof cover 3, there is a pressure sensor 4 located on the top path of the L-shaped probe 34. A signal light 5 is provided on one side of the pressure sensor 4 to receive the signal from the pressure sensor 4. Above the bottom of the leak-proof cover 3, there is a fixing plate for placing the signal light 5 and a storage slot 41 for the pressure sensor 4. The signal light 5 is powered by a battery, and the battery of the signal light 5 is located in the storage slot 41. To prevent ink from contaminating the pressure sensor 4, an ink-resistant pad 42 is attached to the detection hole of the pressure sensor 4 on the bottom of the leak-proof cover 3.

[0023] In a specific implementation of this utility model, the leak-proof cover 3 is inserted into the ink inlet of the ink cartridge 1, and the ink inlet is sealed by the rubber gasket inside the leak-proof cover 3. Then, the syringe 2 is inserted into the ink filling needle rod 31 and injected multiple times until it is full. When the indicator light 5 shows the full signal, the injection is stopped, the leak-proof cover 3 is reversed and removed, and finally the ink cap is used to seal the ink inlet.

[0024] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
