Description

Technical Field

[0001] This utility model belongs to the field of digital printing, and in particular relates to a cleaning and moisturizing component. Background Technology

[0002] After the printing carriage of a digital printing machine stops operating, the printhead needs to be cleaned or moisturized as needed. Existing moisturizing structures not only serve a moisturizing function but also assist in printhead cleaning. During cleaning, the printhead moves above the moisturizing structure, pressing ink against it to expel waste ink into the structure, or other cleaning components scrape off ink droplets adhering to the printhead, causing the droplets to fall into the moisturizing structure. However, when receiving waste ink or droplets, the pressure from the printhead itself or the inertia generated by the cleaning components scraping off droplets can cause ink droplets or waste ink to easily fly out of the moisturizing structure, contaminating other parts of the equipment and increasing the difficulty of cleaning. Summary of the Invention

[0003] The cleaning and moisturizing component provided by this utility model aims to solve the problem in the prior art that other parts of the equipment are easily contaminated, increasing the difficulty of cleaning the equipment.

[0004] This invention is implemented as follows: a cleaning and moisturizing component, used in digital printing equipment for cleaning and moisturizing the printing carriage, includes:

[0005] Support platform;

[0006] The outer plate is fixed on the support platform, and the bottom of the outer plate is provided with a drain outlet and an overflow outlet;

[0007] An inner disk is embedded within and spaced apart from the outer disk. The inner disk communicates with the outer disk and is used to moisturize the printhead or to receive waste ink during printhead cleaning on the printing carriage.

[0008] Furthermore, the support platform is movably provided with a cleaning component above the outer disk, which can remove ink droplets attached to the printhead located above the inner disk when it moves.

[0009] Furthermore, the cleaning component is a scraper or a suction nozzle. When it is a suction nozzle, the suction nozzle is connected to an external air source.

[0010] Furthermore, when the cleaning component is a scraper, the support platform also includes a scraper pressure plate attached to the side of the scraper facing the outer disk, and the top of the scraper pressure plate is provided with a guide slope.

[0011] Furthermore, an ink baffle is provided above the side wall of the outer disk, and the ink baffle is located on one side of the end of the scraper moving in the direction of movement.

[0012] Furthermore, the distance between the outer and inner discs in the direction of movement of the cleaning component is greater than the distance perpendicular to the direction of movement of the cleaning component.

[0013] Furthermore, the length of the cleaning component perpendicular to its direction of movement is greater than that of the inner disc and less than that of the outer disc.

[0014] Furthermore, the bottom of the side wall of the inner disk is provided with notches at intervals, and the notches and the bottom surface of the outer disk form a channel connecting the inner disk and the outer disk.

[0015] Furthermore, the cleaning and moisturizing component also includes a mounting base and a first driving member disposed on the mounting base. The support platform is disposed above the mounting base and is driven to rise and fall by the first driving member. A guide component and an elastic support component are provided between the mounting base and the support platform. The guide component provides guidance for the movement of the support platform, and the elastic support component provides an upward preload force for the support platform when it rises and falls.

[0016] Furthermore, the elastic support component includes:

[0017] A fixing rod, one end of which is fixed to the side of the mounting base facing the support platform;

[0018] A top rod is nested inside the fixed rod and can move up and down relative to the fixed rod, with one end of the top rod abutting against the bottom of the support platform;

[0019] An elastic element is disposed within the fixed rod and provides a preload force to the top rod to abut against the support platform.

[0020] The beneficial effects achieved by this utility model are that, by setting up a nested inner and outer plate structure, in addition to moisturizing the printhead, when cleaning the printhead, the space between the inner and outer plates forms an expanded ink receiving space for the inner plate, and the outer plate can effectively receive ink droplets splashed from the inner plate, which can effectively prevent ink droplets from contaminating other parts of the equipment, thereby continuously maintaining the cleanliness of the equipment and reducing the difficulty of cleaning.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] See Figures 1-2 This utility model provides a cleaning and moisturizing component for cleaning and moisturizing a printing carriage in a digital printing device, including a support platform 1, an outer plate 2, and an inner plate 3. The outer disk 2 is fixed on the support platform 1. The bottom of the outer disk 2 is provided with a drain outlet 22 and an overflow outlet 21. The inner disk 3 is embedded in the outer disk 2 and spaced apart from the outer disk 2. The inner disk 3 is connected to the outer disk 2, so that liquid in the inner disk 3 can flow into the outer disk 2 and be discharged from the outer disk 2 through the overflow outlet 21 or the drain outlet 22. In use, the inner disk 3 is used to moisturize the printhead or to collect waste ink when cleaning the printhead of the print carriage. When the printhead needs to be moisturized, the printhead base plate of the print carriage presses against the upper periphery of the inner disk 3. The printhead is contained in the inner disk 3 in a sealed space, thereby achieving the goal of moisturizing the printhead. When the printhead needs to be cleaned, the print carriage or the cleaning and moisturizing component is moved to a preset position above the inner disk 3. At this time, the ink droplets attached to the printhead can be cleaned by the cleaning component or the printhead can spray out ink by pressing the ink, thereby achieving the goal of cleaning the printhead. Waste liquid can drip into the inner disk 3 and then flow into the outer disk 2 for discharge.

[0030] By setting up a nested inner disk 3 and outer disk 2 structure, in addition to keeping the printhead moist, when cleaning the printhead, the space between the inner disk 3 and outer disk 2 forms an expanded ink receiving space for the inner disk 3, and the outer disk 2 can effectively receive ink droplets splashed from the inner disk 3, which can effectively prevent ink droplets from contaminating other parts of the equipment, thereby continuously maintaining the cleanliness of the equipment and reducing the difficulty of cleaning.

[0031] The cleaning and moisturizing component provided by this utility model can effectively catch splashed ink during use, preventing contamination of other parts of the equipment, maintaining the cleanliness of the equipment, and reducing the difficulty of cleaning.

[0032] See Figure 1 Furthermore, a cleaning component 4 is movably provided on the support platform 1 above the outer disk 2. When the cleaning component 4 moves, it can remove ink droplets attached to the printhead located above the inner disk 3. By setting the cleaning component 4 on the support platform 1 and removing ink droplets attached to the printhead located at a preset position on the inner disk 3, the cleaning and moisturizing functions can be integrated, simplifying the structure and saving costs.

[0033] See Figure 1 Specifically, the support platform 1 is equipped with a slider 11, a slide rail 12, and a second driving component (not shown in the figure). The slide rail 12 is located on at least one side of the outer disk 2. The slider 11 is slidably mounted on the slide rail 12. The second driving component drives the slider 11 to move on the slide rail 12. The cleaning component 4 is connected and fixed to the slider 11, thereby driving the cleaning component 4 to move. In this embodiment, two slide rails 12 can be provided, with the two slide rails 12 located on opposite sides of the outer disk 2.

[0034] Furthermore, the support platform 1 is equipped with displacement sensors 13 at the starting and ending ends of the slider 11 in the direction of movement. When the slider touches the displacement sensor 13, the second driving member controls the slider 11 to stop moving.

[0035] Specifically, the cleaning component 4 is a scraper or a nozzle. When the cleaning component 4 is a scraper, the scraper can contact the printhead surface and scrape off the ink droplets attached to the printhead when it moves. When the cleaning component 4 is a nozzle, the nozzle is connected to an external air source and can suck away the ink attached to the printhead during its movement.

[0036] See Figure 1 , Figure 3 Furthermore, when the cleaning component 4 is a scraper, the support platform 1 also includes a scraper pressure plate 5 attached to the side of the scraper facing the outer disk 2. The top of the scraper pressure plate 5 is provided with a guide slope 51. The guide slope 51 allows the ink scraped by the scraper to flow into the outer disk 2 or inner disk 3 along the guide slope 51 when the scraper is scraping ink, so that the ink will not accumulate in the mounting part of the scraper, thus preventing the scraper from becoming moldy and difficult to clean.

[0037] Specifically, the guide slope 51 can be continuous or intermittent. A continuous structure facilitates processing, while an intermittent structure ensures that the ink flows evenly into the inner disk 3 or outer disk 2 along the length of the scraper.

[0038] See Figures 1-2Furthermore, an ink baffle 6 is provided above the side wall of the outer disk 2, and the ink baffle 6 is located on one side of the end of the scraper in the direction of movement. In this way, when the cleaning component 4 moves to remove ink droplets from the printhead, the inertia caused by the removal process can be blocked by the ink baffle 6 and fall into the outer disk 2, thereby preventing ink from contaminating other parts of the equipment.

[0039] Furthermore, the distance between the outer disk 2 and the inner disk 3 in the direction of movement of the cleaning component 4 is greater than the distance perpendicular to the direction of movement of the cleaning component 4. This provides sufficient distance between the outer disk 2 and the inner disk 3 in the direction of movement of the cleaning component 4 to receive ink splashes during the movement of the cleaning component 4, while reducing the distance between the outer disk 2 and the inner disk 3 perpendicular to the direction of movement of the cleaning component 4 reduces the overall size of the cleaning and moisturizing assembly, saving material costs and space.

[0040] See Figure 1 Furthermore, the length of the cleaning component 4 perpendicular to its direction of movement is greater than that of the inner disk 3 and less than that of the outer disk 2. That is, the two ends of the cleaning component 4 are located between the inner disk 3 and the outer disk 2. In this way, when cleaning the ink droplets attached to the printhead, it can ensure that all printheads are covered to clean all printheads, and it can also avoid being too long and causing the waste ink to flow out of the outer disk 2.

[0041] See Figure 1 Furthermore, the bottom of the side wall of the inner plate 3 is provided with notches 31 at intervals. The notches 31 and the bottom surface of the outer plate 2 form a channel connecting the inner plate 3 and the outer plate 2, which facilitates the connection between the inner plate 3 and the outer plate 2. Specifically, the notches 31 can be arranged on the four sides of the inner plate 3, which can ensure that the liquid in the inner plate 3 can flow into the outer plate 2 quickly.

[0042] See Figure 4 Furthermore, the cleaning and moisturizing component also includes a mounting base 7 and a first drive component 8 mounted on the mounting base 7. The support platform 1 is located above the mounting base 7 and is driven to rise and fall by the first drive component 8. The support platform 1 drives the inner plate 3 and the outer plate 2 to move to a preset position, thereby meeting the moisturizing or cleaning needs of the nozzle. A guide component 9 and an elastic support component 10 are provided between the mounting base 7 and the support platform 1. The guide component 9 provides guidance for the movement of the support platform 1, so that the support platform 1 can maintain balanced rise and fall in the horizontal direction. The elastic support component 10 provides an upward preload force to the support platform 1 during rise and fall, so that there is always an upward lifting force on the support platform 1 during the rise and fall process. When the first drive component 8 drives the support platform 1 to fall, the support platform 1 will not cause the inner plate 3 and the outer plate 2 to drop suddenly, thereby avoiding the liquid in the inner plate 3 and the outer plate 2 from splashing out. When the first drive component 8 drives the support platform 1 to rise, the elastic support component 10 can provide a certain buoyancy to the support platform 1, which can reduce the power required by the first drive component 8 and reduce the power of the first drive component 8, thus saving costs.

[0043] See Figure 5 Furthermore, the elastic support assembly 10 includes a fixed rod 101, a top rod 102, and an elastic element 103. One end of the fixed rod 101 is fixed to the side of the mounting base 7 facing the support platform 1, providing installation space for the top rod 102. The top rod 102 is nested within the fixed rod 101 and can move up and down relative to the fixed rod 101. One end of the top rod 102 abuts against the bottom of the support platform 1. The elastic element 103 is disposed within the fixed rod 101 and provides a pre-tightening force to the top rod 102 to abut against the support platform 1. The elastic element 103 ensures that the top rod 102 always abuts against the support platform 1.

[0044] See Figure 5 Specifically, the fixed rod 101 has a cavity 1011 inside, one end of the push rod 102 can be inserted into the cavity 1011 telescopically, and the other end extends out of the cavity 1011 and abuts against the support platform 1. The elastic element 103 is placed in the cavity 1011 and abuts against the end of the push rod 102.

[0045] See Figure 5 Specifically, the guide assembly 9 includes a matching guide sleeve 91 and a guide rod 92. The guide sleeve 91 is fixed on the mounting base 7, and the guide rod 92 is slidably engaged with the support platform 1 and one end is connected and fixed to the support platform 1. When the first driving member 8 drives the support platform 1 to rise and fall, the support platform 1 can drive the guide rod 92 to extend and retract within the guide sleeve 91.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
