Description

Technical Field

[0001] This invention relates to the field of digital inkjet printing technology, specifically to a protective sealing device for inkjet printer nozzles to prevent nozzle clogging and its usage method. Background Technology

[0002] Digital inkjet printers have broken through the bottlenecks of digital printing technology, achieving true one-page printing, no plate making required, and full-color image completion in one pass. The extremely low printing cost and high-quality printing results are more economical and convenient than traditional printing systems. Minimal system investment, digital operation, and limited space occupation give the system a greater market prospect. It is the best complement to traditional printing and a replacement product for traditional printing presses. During the digital inkjet printing process, a printhead protection and sealing device is often required.

[0003] Patent application publication number CN201291637Y discloses an inkjet printer printhead protective cover device, belonging to the field of inkjet printing equipment. Existing technologies simply prevent ink solvent evaporation, which is easily lost. This invention includes a cover body and a printhead mounting bracket. One side of the printhead mounting bracket is equipped with a transmission component connected to the cover body. The cover body contains a liquid absorbent material. Its advantage lies in that the liquid absorbent material inside the cover absorbs ink solvent, covering and wetting the nozzle, thereby reducing or even preventing the evaporation of residual ink solvent (or ink). This significantly extends the time for residual ink in the nozzle to dry and clump when the printhead is not in use, preventing the nozzle from becoming clogged due to ink drying. It achieves unobstructed nozzle maintenance when the printhead is not in use, is not easily lost, has a compact structure, and the covering and opening actions are flexible and accurate.

[0004] However, the above-mentioned devices still have some drawbacks in actual use. The most obvious one is that the overall operation steps are cumbersome when dealing with different types of nozzles, which may affect the work efficiency of the staff. In addition, it is usually not convenient to clean and dry the surface after use, which may cause some inconvenience to the user.

[0005] Therefore, it is necessary to invent a protective sealing device for inkjet printer nozzles to prevent nozzle clogging and a method for using it to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a protective sealing device and method for inkjet printer nozzles to avoid nozzle clogging. It has the advantages of simple operation and easy cleaning, and solves the problems of complex operation and inconvenient cleaning.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a protective sealing device for inkjet printer nozzles to prevent nozzle clogging, comprising an aluminum base plate, side plates welded to both sides of the aluminum base plate, fixing screws passing through both sides of the top of the aluminum base plate, a connecting seat welded to the center of the top of the aluminum base plate, a protective cover connected to the top of the connecting seat, a connecting pipe connected to the top of the protective cover, ball screws passing through both sides of the bottom of the connecting seat, and a cleaning mechanism provided on the rear side of the aluminum base plate, the cleaning mechanism comprising a vacuum air-liquid dual-purpose pump and a material storage shell.

[0008] Preferably, the aluminum base plate has a discharge hole on its front side, and the front side of the right side of the storage shell is connected to a drain valve.

[0009] Preferably, the front side of the vacuum air-liquid dual-purpose pump is bolted to the rear side of the aluminum base plate, and the front side of the storage shell is welded to the rear side of the aluminum base plate.

[0010] Preferably, the right side of the rear side of the storage shell is connected to a liquid inlet pipe, and a dust cover is threaded onto the surface of the liquid inlet pipe.

[0011] Preferably, positioning screws are provided through both sides of the top of the connector, and the number of positioning screws is at least 8.

[0012] Preferably, an activated carbon mesh plate is provided through the left side of the storage shell, and a cylindrical filter element is connected to the right side of the activated carbon mesh plate. A partition is welded to the bottom of the inner cavity of the storage shell, and a servo motor is bolted to the left side of the partition. The output end of the servo motor is welded to the right side of the cylindrical filter element.

[0013] Preferably, a support bearing is fixedly sleeved on the left side of the cylindrical filter element surface, and a support rod is welded to the top and bottom of the support bearing. The side of the support rod near the storage shell is welded to the inner wall of the storage shell.

[0014] Preferably, the front side of the vacuum air-hydraulic pump extends to the top of the aluminum base plate and is connected to a horizontal pipe. A through hole is opened on the front side of the horizontal pipe. A material extraction pipe is connected to the rear side of the vacuum air-hydraulic pump. The side of the material extraction pipe away from the vacuum air-hydraulic pump extends to the front side of the inner cavity of the storage shell. A connecting pipe is connected to the front side of the material extraction pipe. The front side of the connecting pipe is connected to the storage shell. Electric valves are fixedly installed on the surface of the connecting pipe and the surface of the material extraction pipe.

[0015] A method for using a protective sealing device for inkjet printer printheads to prevent nozzle clogging includes the following steps:

[0016] A: When installation is required, the user can blindly insert the rubber seal into the corresponding recessed hole on the aluminum base plate. No non-woven fabric is needed during this process to precisely position the printhead nozzles, ensuring a complete seal and providing dust and light protection for UV printheads. It offers particularly good protection for water-based printheads. After the connecting tube is attached, slight ink pressure will cause the ink to adhere tightly to the printhead within the rubber seal, preventing the nozzles from drying out and becoming clogged.

[0017] B: When you want to clean the surface after use, you can start the vacuum air-hydraulic pump through the external controller and then open the corresponding electric valve. The vacuum air-hydraulic pump will draw the cleaning liquid inside the storage shell into the horizontal pipe through the suction pipe, and then spray it out through the through hole to clean the top of the aluminum base plate. The cleaning liquid after cleaning will be discharged through the discharge hole.

[0018] C: Then the user can open the corresponding electric valve, close another electric valve, and then start the vacuum air-liquid dual-purpose pump and servo motor. The vacuum air-liquid dual-purpose pump draws the gas that has been filtered by the activated carbon mesh and the cylindrical filter element in sequence through the connecting pipe to the material extraction pipe, and then sends it to the inner cavity of the horizontal pipe. Finally, it is sprayed out through the through hole to achieve a better residual moisture removal function.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This invention, through the combination of a vacuum-liquid dual-purpose pump, a material extraction pipe, an activated carbon mesh plate, a support bearing, a connecting pipe, and an electric valve, facilitates the filtration of gas and the extraction of the filtered gas into a horizontal pipe for uniform spraying to blow away excess water droplets.

[0021] 2. By setting up a cylindrical filter element, servo motor, partition, through hole, storage shell, fixing screw and discharge hole, the present invention can spray the cleaning liquid evenly, so as to rinse the surface of the aluminum base plate and remove any particulate impurities and ink stains that may exist.
