Description

Technical Field

[0001] This utility model relates to the field of printer printhead cleaning technology, and more particularly to a UV inkjet printer printhead cleaning device. Background Technology

[0002] With the widespread application of UV inkjet printing technology, inkjet printers are increasingly used in image output, signage production, and decoration industries. Especially today, with the growing demand for high-quality image printing, UV inkjet printers, with their high resolution, wide color gamut, and environmentally friendly solvent-free features, have become the mainstream printing equipment in the industry. However, UV inkjet printers often face problems such as printhead clogging and ink residue during use, which can lead to a decline in print quality and, in severe cases, even affect the normal operation of the equipment. Therefore, printhead cleaning is a key step in maintaining the normal operation of UV inkjet printers and extending their service life.

[0003] Traditional printhead cleaning methods typically involve mixing cleaning solution and water in a specific ratio using a syringe, injecting the mixture into the printhead, and then squeezing the syringe to increase water pressure and flush out solidified ink particles. The solidified ink is then dissolved by the cleaning solution. However, in practice, the dissolution rate of the cleaning solution is slow, requiring the operator to hold the printhead and syringe for an extended period, which is extremely inconvenient. Furthermore, the dissolved ink can cause contamination after being discharged. Therefore, a UV inkjet printer printhead cleaning device is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a UV inkjet printer printhead cleaning device, which aims to improve the extremely inconvenient syringe rinsing operation in the prior art.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2, Figure 3 and Figure 5 This utility model provides an embodiment of a UV inkjet printer printhead cleaning device, comprising a housing 1, a water supply assembly installed on the top of the housing 1, a vertical rod 10 fixedly connected to the top of the housing 1, a round rod 9 fixedly connected to the top of the housing 1, a sleeve 8 slidably connected to the outer periphery of the round rod 9, an elastic component installed in the middle of the sleeve 8, a printhead body 6 installed between the sleeve 8 and the vertical rod 10, a flow divider 5 installed on the top of the printhead body 6, a connecting pipe 4 fixedly connected to the top of the flow divider 5, the connecting pipe 4 being connected to the water supply assembly, and a filter assembly installed in the middle of the housing 1. The elastic component includes a stop block 19, which is fixedly connected to the top of the round rod 9. A compression spring 20 is sleeved on the outer periphery of the round rod 9. The water supply component includes a water pump 2, which is fixedly connected to the top of the tank 1. A water pipe 3 is fixedly connected to the input end of the water pump 2. The other end of the water pipe 3 is fixedly connected to the middle of the tank 1. Connecting pipe 1 4 and connecting pipe 2 14 are both fixedly connected to the output end of the water pump 2. A rubber pad 11 is fixedly connected to the end of the upright rod 10 and the sleeve 8 away from the tank 1. A crossbar 7 is fixedly connected to the middle of the sleeve 8. A sealing ring 15 is installed in the middle of the diverter 5. First, the sleeve 8 is lifted by pulling the crossbar 7, and the printhead body 6 is placed on top of the upright 10. When the sleeve 8 is pulled, it will cause the compression spring 20 to squeeze the stop block 19. After the sleeve 8 is released, the compression spring 20 will push the sleeve 8 to squeeze the printhead body 6, thereby fixing the printhead body 6 between the sleeve 8 and the upright 10. The rubber pad 11 will prevent the printhead body 6 from being worn. Then, the distributor 5 is inserted into the ink inlet of the printhead body 6. At the same time, the sealing ring 15 will improve the sealing between the distributor 5 and the ink inlet of the printhead body 6, ensuring sufficient water pressure. The water pump 2 will be driven to draw water from the tank 1 and slowly input into the printhead body 6 through the connecting pipe 4, thereby rinsing the printhead body 6. This way, the operator does not need to hold the printhead body 6 and push the syringe for a long time.

[0035] Reference Figure 1 , Figure 2 and Figure 6A heater 13 is fixedly connected to the outside of the housing 1. A heating rod 16 is installed in the middle of the heater 13. The other end of the heating rod 16 passes through and is fixedly connected to the middle of the housing 1. A nozzle 12 is fixedly connected to the top of the housing 1. A connecting pipe 14 is fixedly connected to the middle of the nozzle 12. The other end of the connecting pipe 14 is connected to the water supply assembly. Before rinsing, the heater 13 is activated to heat the water in the housing 1 through the heating rod 16. After the water is heated to a suitable temperature, the water pump 2 rinses the printhead body 6 through the distributor 5. At the same time, the connecting pipe 14 diverts some rinsing liquid into the nozzle 12. The nozzle 12 then rinses the ink outlet of the printhead body 6. This warm water rinsing accelerates the dissolution rate of the ink in the printhead body 6 and, under the action of the nozzle 12, rinses the ink outlet of the printhead body 6, further increasing the dissolution rate of the ink so that the distributor 5 can flush the ink out.

[0036] Reference Figure 2 and Figure 4 The filter assembly includes a frame 17, which is fixedly connected to the inner top of the housing 1. From top to bottom, a filter plate 18, a gravel layer 21, and an activated carbon plate 22 are sequentially fixedly connected to the middle of the frame 17. The frame 17 is located directly below the connecting pipe 4. After rinsing, wastewater falls into the frame 17 through a notch in the housing 1. Under the action of the filter plate 18, gravel layer 21, and activated carbon plate 22, the wastewater undergoes multi-layer filtration, thereby separating the ink and water, allowing the water to be recycled and reducing water waste.

[0037] Working principle: First, pull the sleeve 8 to lift it up, placing the printhead body 6 on top of the upright 10. When the sleeve 8 is pulled, it will cause the compression spring 20 to squeeze the stop block 19. After the sleeve 8 is released, under the push of the compression spring 20, the sleeve 8 will squeeze the printhead body 6, thereby fixing the printhead body 6 between the sleeve 8 and the upright 10. Then, insert the distributor 5 into the ink inlet of the printhead body 6, driving the water pump 2 to slowly input water into the printhead body 6 for rinsing. The wastewater after rinsing can fall into the filter assembly through the notch on the housing 1 for filtration, thereby recycling the water and facilitating cleaning, reducing the cleaning time for operators.

[0038] Before rinsing, the heater 13 is activated to heat the water in the housing 1 through the heating rod 16. After the water is heated to a suitable temperature, the water pump 2 rinses the printhead body 6 through the distributor 5. At the same time, the connecting pipe 2 14 will divert some rinsing liquid into the nozzle 12, and rinse the ink outlet of the printhead body 6 through the nozzle 12, thereby further improving the ink dissolution efficiency in the printhead body 6.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
