Description

Technical Field

[0001] This utility model belongs to the field of digital printing, and in particular relates to ink receiving components. Background Technology

[0002] In digital printing equipment, the printhead assembly, as a core component, requires regular cleaning and maintenance to ensure printing quality. Printhead cleaning is divided into internal and external cleaning. Internal cleaning, after meeting cleaning conditions, involves using pressure to eject ink from the printhead to prevent clogging. However, during ink ejection, pressure causes some ink to spray out in a mist-like form, a phenomenon known as ink splatter. Ink splatter can pollute the surrounding environment, increasing the difficulty of cleaning. Utility Model Content

[0003] This invention provides an ink receiving assembly, which aims to solve the problem in the prior art that ink splatter easily occurs during printhead cleaning, causing pollution of the surrounding environment and increasing the difficulty of cleaning.

[0004] This utility model is implemented as follows: an ink receiving assembly includes:

[0005] The ink receiving tray includes an ink receiving area and a closed area, wherein the ink receiving area is used to receive ink ejected from the printhead;

[0006] A flow guide plate is installed on the ink receiving area, and the flow guide plate is provided with several flow guide channels that connect to the inside of the ink receiving tray;

[0007] An exhaust device is provided on the enclosed area. The exhaust device is activated when the ink receiving area receives ink to extract the gas inside the ink receiving tray to the outside.

[0008] Furthermore, the guide plate is movably disposed on the ink receiving area in the direction of the closed area, and when the guide plate moves in the direction of the closed area, the ink receiving area is in an open state.

[0009] Furthermore, when the guide plate moves toward the enclosed area, the guide plate can move into the interior of the enclosed area.

[0010] Furthermore, the ink receiving tray has slide rails on its opposite side walls, the slide rails spanning the ink receiving area and the enclosed area, and the guide plate is slidably disposed on the slide rails.

[0011] Furthermore, the ink receiving tray includes a tray body with a receiving cavity and the top of the receiving cavity being open, and a cover plate. The cover plate covers one side of the top of the tray body to form the closed area. The exhaust device is fixed on the cover plate. The remaining area at the top of the tray body is the ink receiving area. In terms of vertical height, the cover plate is set higher than the guide plate.

[0012] Furthermore, the bottom of the disc body is provided with a waste discharge port, which is located at one end of the closed area near the ink receiving area. The bottom walls of the disc body, the ink receiving area, and the closed area are all inclined towards the waste discharge port.

[0013] Furthermore, the enclosed area is provided with an exhaust port, and the suction end of the exhaust device is connected to the exhaust port.

[0014] Furthermore, a filter element is provided between the exhaust port and the suction end of the exhaust device.

[0015] Furthermore, the guide plate has an extension plate on the side facing the closed area, the extension plate extends toward the bottom wall of the ink receiving tray, and an airflow channel is formed between the extension plate and the bottom wall of the ink receiving tray.

[0016] The beneficial effects achieved by this utility model are that by setting an exhaust device on the ink receiving tray and activating the exhaust device when the ink receiving tray receives the sprayed ink, the airflow above the guide plate can flow into the ink receiving tray, thereby effectively sucking the mist ink into the ink receiving tray and greatly reducing ink splatter.

[0022] 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.

[0023] See Figure 1This utility model provides an ink receiving assembly, including an ink receiving tray 1, a flow guide plate 2, and an exhaust device 3. The ink receiving tray 1 includes an ink receiving area and a closed area. The ink receiving area receives ink ejected from the printhead 101. The flow guide plate 2 covers the ink receiving area and has several flow channels (not shown in the figure) connecting to the interior of the ink receiving tray 1. The flow guide plate 2 prevents debris from falling into the ink receiving area. If debris mixes with the ink in the ink receiving area, it will make cleaning the ink receiving tray 1 difficult. Therefore, the flow guide plate 2 reduces the cleaning difficulty of the ink receiving tray 1. Furthermore, the flow guide plate 2 can reduce the gap between the ink receiving area and the outside. The air intake device 3 is located in the enclosed area. It is used to draw out the gas inside the ink receiving tray 1 when the ink receiving area receives ink. This allows the airflow from the printhead 101 to flow into the ink receiving tray 1, ensuring the recycling of waste ink in the ink receiving tray 1. The air intake device 3 is located in the enclosed area. It is used to start working when the ink receiving area receives ink to draw the gas inside the ink receiving tray 1 to the outside. This allows the airflow to flow from the top of the air intake device 3 through the air intake channel into the ink receiving tray 1 after the air intake device 3 is turned on.

[0024] During operation, the printhead module 10 moves above the guide plate 2 and then descends to a preset position. The printhead 101 of the printhead module 10 sprays ink out of the guide plate 2 with a certain pressure to avoid clogging of the printhead 101, thereby cleaning the printhead 101 or replacing the ink. At the same time, the exhaust device 3 is activated. The airflow enters the ink receiving tray 1 from above the guide plate 2 through the guide channel and flows out from the air outlet of the exhaust device 3, thus forming an airflow path. This airflow can effectively draw the mist-like ink generated when the printhead 101 sprays ink into the ink receiving tray 1, thereby greatly reducing ink splatter.

[0025] By installing an exhaust device 3 on the ink receiving tray 1 and activating the exhaust device 3 when the ink receiving tray 1 receives the ejected ink, the airflow above the guide plate 2 can flow into the ink receiving tray 1, thereby effectively drawing the mist ink into the ink receiving tray 1 and greatly reducing ink splatter.

[0026] The ink receiving component provided by this utility model can reduce ink splatter when discharging ink from the printhead, thereby avoiding the environmental pollution problems caused by ink splatter.

[0027] See Figures 2-3 Specifically, the enclosed area is provided with an exhaust port 11, and the suction end of the exhaust device 3 is connected to the exhaust port 11, so that the suction end of the exhaust device 3 is connected to the inside of the ink receiving tray 1.

[0028] See Figure 2 Furthermore, a filter element 5 is provided between the exhaust port 11 and the suction end of the exhaust device 3. The filter element 5 can filter ink droplets, preventing ink droplets from entering the exhaust device 3 with the airflow and causing pollution. Specifically, the filter element 5 can be, but is not limited to, filter cotton.

[0029] Furthermore, the guide plate 2 is movably disposed on the ink receiving area towards the closed area. When the guide plate 2 moves towards the closed area, the ink receiving area is in an open state. By movably disposing of the guide plate 2, when it is necessary to inspect the printhead 101 of the printhead module 10, the printhead module 10 can be moved above the ink receiving tray 1, and the guide plate 2 can be moved towards the closed area, thereby utilizing the space of the ink receiving area to inspect the printhead 101.

[0030] Furthermore, when the guide plate 2 moves towards the closed area, it can be moved into the interior of the closed area, meaning the guide plate 2 can be stored inside the closed area. This effectively reduces the volume of the ink receiving tray 1, thereby reducing the space occupied by the ink receiving tray 1 on the equipment.

[0031] See Figures 2-3 Furthermore, slide rails 4 are provided on the opposite side walls of the ink receiving tray 1, spanning the ink receiving area and the enclosed area, and the guide plate 2 is slidably mounted on the slide rails 4. By providing slide rails 4, the movement of the guide plate 2 can be facilitated. Specifically, the slide rails 4 include a first slide rail (not shown in the figure) provided on the ink receiving tray 1 and a second slide rail (not shown in the figure) provided on the guide plate 2, with the first slide rail and the second slide rail slidingly engaged.

[0032] See Figure 2 Furthermore, the ink receiving tray 1 includes a tray body 1a with a receiving cavity and an open top, and a cover plate 1b. The cover plate 1b covers one side of the top of the tray body 1a to form a closed area. An exhaust device 3 is provided on the cover plate 1b, and the aforementioned exhaust hole 11 is provided on the cover plate 1b. The remaining area at the top of the tray body 1a is the ink receiving area. In terms of vertical height, the cover plate 1b is set higher than the guide plate 2. This arrangement allows the guide plate 2 to move to the bottom of the cover plate 1b and be stored in the closed area when it moves towards the closed area.

[0033] See Figure 3 Furthermore, the bottom of the disk body 1a is provided with a waste discharge port 12, which is used to discharge waste ink in the disk body 1a. The waste discharge port 12 is located at the end of the closed area near the ink receiving area. When it is necessary to clean the waste discharge port 12, the guide plate 2 can be moved towards the closed area to facilitate the cleaning of the waste discharge port 12. The bottom walls of the disk body 1a corresponding to the ink receiving area and the closed area are all inclined towards the waste discharge port 12, so that waste ink can be easily collected towards the waste discharge port 12 and discharged outside the ink receiving disk 1.

[0034] See Figure 2Furthermore, the guide plate 2 has an extension plate 21 on the side facing the enclosed area. The extension plate 21 extends towards the bottom wall of the ink receiving tray 1, forming an airflow channel between the extension plate 21 and the bottom wall of the ink receiving tray 1. Specifically, the bottom wall of the ink receiving tray 1 is the bottom wall of the tray body 1a. The extension plate 21 reduces the channel between the guide plate 2 and the bottom wall of the ink receiving tray 1, thereby increasing the gas flow rate and thus improving the suction force of the exhaust device 3 on the flying ink.

[0035] 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.
