Description

Technical Field

[0001] This utility model relates to the field of inkjet printing technology, and in particular to a waste ink collection device. Background Technology

[0002] During continuous printing operations, inkjet printers often need to adjust print specifications or colors. When operators adjust print specifications or switch colors, the printhead settings need to be changed accordingly to adapt to the new printing requirements.

[0003] However, a key issue arises during printhead adjustment. Inevitably, some waste ink remains after the printhead completes its previous print job. If this waste ink isn't removed promptly and effectively, it may act on the printing media along with the new ink ejected from the printhead in subsequent print jobs, severely impacting print quality and causing issues such as blurry images, color deviations, and streaks. Therefore, to ensure print quality, the waste ink on the printhead must be thoroughly removed after adjustment.

[0004] Currently, the main device on the market for scraping waste ink off printheads is the scraper. However, in actual use, existing scrapers have many problems when scraping off waste ink. When the scraper contacts the printhead and scrapes off the waste ink, the interaction force between the scraper and the waste ink easily causes ink splatter. This splattered ink not only wastes ink and increases printing costs, but also spreads to surrounding equipment and the work environment, polluting the work environment and potentially posing a health hazard to operators. Furthermore, because the scraped waste ink is scattered, it is difficult to collect and properly dispose of, further complicating equipment maintenance and environmental cleanup. Utility Model Content

[0005] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies, and this utility model provides a waste ink collection device.

[0006] This utility model provides the following technical solution: A waste ink collection device includes a base, a collection hopper, a scraper assembly, and a drive assembly.

[0007] The collection hopper is mounted on the base, and the bottom of the collection hopper is filled with a moisturizing solution. A splash guard is horizontally arranged inside the collection hopper, positioned above the moisturizing solution, and the splash guard has evenly distributed mesh holes. The ink scraper assembly is mounted on the base, and the ink scraper assembly includes a scraper blade and a movable seat, with the scraper blade mounted on the movable seat. The drive assembly is mounted between the base and the movable seat. The drive assembly can drive the movable seat to move the scraper blade back and forth horizontally above the splash guard, thereby scraping away waste ink on the printhead above the splash guard.

[0008] As a further improvement to the above technical solution, a first collection groove is provided at the upper end of the movable seat, and the scraper is installed in the first collection groove and extends out from the upper opening of the first collection groove.

[0009] As a further improvement to the above technical solution, a first drain outlet is provided at the lower end of one side of the first collection tank, and a second collection tank corresponding to the first collection tank is provided on the base. The upper opening of the second collection tank is located below the first drain outlet, and a second drain outlet is provided at the lower end of the second collection tank.

[0010] As a further improvement to the above technical solution, the scraper is provided as a plurality of scrapers, and these scrapers are arranged in a direction perpendicular to the direction in which the drive component drives the scraper to move, and each scraper is installed in the first collection groove.

[0011] As a further improvement to the above technical solution, the drive assembly includes a drive motor and a transmission belt. The drive motor and the transmission pulley of the transmission belt are both mounted on the base. The drive motor and the transmission pulley of the transmission belt are in a transmission cooperation. The movable seat is fixedly connected to the transmission belt through a connector. The drive motor drives the transmission pulley to rotate, which in turn drives the transmission belt to move the movable seat in the horizontal direction.

[0012] As a further improvement to the above technical solution, the base is provided with a guide rail, and the movable seat is provided with a slider corresponding to the guide rail. The slider is engaged with the guide rail, and the driving component can drive the slider to move along the guiding direction of the guide rail.

[0013] As a further improvement to the above technical solution, two guide rails are provided, and the two guide rails are symmetrically arranged on both sides of the collection hopper.

[0014] As a further improvement to the above technical solution, a photoelectric sensing device is provided on the side of the base near the guide rail, and a sensing element corresponding to the photoelectric sensing device is provided on the movable seat; when the sensing element passes through the sensing area of ​​the photoelectric sensing device along with the movable seat, the photoelectric sensing device can sense the passing signal of the sensing element and thereby locate the position of the sensing element.

[0015] As a further improvement to the above technical solution, multiple splash guards are provided along the vertical direction.

[0016] As a further improvement to the above technical solution, the bottom of the collecting hopper is conical, and a third drain port is provided at the lowest end of the bottom of the collecting hopper.

[0017] Compared with related technologies, the beneficial effects of this utility model are: The waste ink collection device provided by this utility model requires the operator to first use the movable function of the inkjet equipment to move the printhead that needs to be scraped to the top of the collection hopper.

[0018] Once the printhead is in place, the ink scraping process begins. At this point, the drive unit, via a transmission mechanism, actuates the movable seat within the ink scraping assembly. The movable seat, carrying the connected scraper blade, moves in a regular reciprocating motion along the horizontal direction. During this movement, the scraper blade contacts the printhead surface, and the relative motion between them efficiently scrapes away waste ink from the printhead. This reciprocating motion ensures that waste ink on the printhead surface is thoroughly cleaned, leaving no residue.

[0019] The waste ink scraped off by the scraper doesn't fall directly into the collection hopper; instead, it first lands on a specially designed splash guard inside the hopper. This splash guard plays a crucial buffering role, effectively slowing down the speed and impact of the falling waste ink, thus significantly reducing splashing when it enters the collection hopper. If the waste ink falls directly into the collection hopper, its high speed makes it prone to splashing upon contact with the bottom of the hopper or other components, causing secondary contamination and increasing the difficulty of subsequent cleaning. The splash guard effectively solves this problem.

[0020] Waste ink falling onto the splash guard can pass through the mesh on the splash guard and fall into the collection hopper. In this way, the waste ink is collected in a relatively enclosed space, which facilitates subsequent centralized processing. Operators can regularly clean and recycle the waste ink in the collection hopper, which not only avoids pollution of the production site environment by waste ink, but also reduces the corrosion and damage of waste ink to production equipment, thus extending the service life of the equipment.

[0021] In addition, the collection hopper is filled with a moisturizing solution, such as water. This solution creates a relatively humid environment within the collection hopper, effectively maintaining humidity above it. This humid environment offers numerous benefits to the scraper. Because the scraper comes into frequent contact with waste ink during the scraping process, some components of the waste ink may adhere to its surface, becoming difficult to remove once dried. The humidity above the collection hopper ensures the scraper surface remains moist, preventing the waste ink adhering to it from drying and solidifying. This makes subsequent cleaning of the scraper much easier; it can be cleaned simply with water or a simple cleaning tool, significantly improving cleaning efficiency and reducing costs.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0031] Combination Figure 3 , Figure 4 As shown, an embodiment of this utility model provides a waste ink collection device, including a base 100, a collection hopper 200, a scraper assembly 300, and a drive assembly 400.

[0032] The collection hopper 200 is mounted on the base 100. The bottom of the collection hopper 200 is filled with a moisturizing solution. A splash guard 210 is horizontally arranged inside the collection hopper 200, located above the moisturizing solution. The splash guard 210 has evenly distributed mesh holes. The scraper assembly 300 is mounted on the base 100. The scraper assembly 300 includes a scraper 310 and a movable seat 320. The scraper 310 is mounted on the movable seat 320. The drive assembly 400 is mounted between the base 100 and the movable seat 320. The drive assembly 400 can drive the movable seat 320 to move the scraper 310 back and forth horizontally above the splash guard 210, thereby scraping off the waste ink on the printhead above the splash guard 210.

[0033] In the waste ink collection device provided in this embodiment, during use, the operator first uses the moving function of the inkjet equipment to move the printhead that needs to be scraped to the top of the collection hopper 200.

[0034] Once the printhead is in place, the ink scraping process begins. At this time, the drive assembly 400, through a transmission mechanism, drives the movable seat 320 in the ink scraping assembly 300. The movable seat 320, carrying the connected scraper 310, moves in a regular reciprocating motion along the horizontal direction. During this movement, the scraper 310 contacts the printhead surface, and the relative motion between them efficiently scrapes away waste ink from the printhead. This reciprocating motion ensures that waste ink on the printhead surface is thoroughly cleaned, leaving no residue.

[0035] The waste ink scraped off by the scraper 310 does not fall directly into the collection hopper 200. Instead, it first falls onto a specially designed splash guard 210 inside the collection hopper 200. The splash guard 210 plays a crucial buffering role here, effectively slowing down the speed and impact of the falling waste ink, thus greatly reducing the problem of splashing when the waste ink falls into the collection hopper. If the waste ink falls directly into the collection hopper 200, due to its high falling speed, it is easy to splash when it comes into contact with the bottom of the collection hopper 200 or other components, which not only causes secondary pollution of the waste ink but also increases the difficulty of subsequent cleaning. The presence of the splash guard 210 effectively solves this problem.

[0036] Waste ink falling onto the splash guard 210 can pass through the mesh on the splash guard 210 and fall into the collection hopper 200. In this way, the waste ink is collected in a relatively enclosed space, which facilitates subsequent centralized processing. Operators can regularly clean and recycle the waste ink in the collection hopper 200, which not only avoids pollution of the production site environment by waste ink, but also reduces the corrosion and damage of waste ink to production equipment, thus extending the service life of the equipment.

[0037] In addition, the collection hopper 200 is filled with a moisturizing solution, such as water. This solution creates a relatively humid environment within the collection hopper 200, effectively maintaining humidity above it. This humid environment offers numerous advantages for the scraper 310. Since the scraper 310 comes into frequent contact with waste ink during the scraping process, some components of the waste ink may adhere to its surface, becoming difficult to clean once dried. The humidity above the collection hopper 200 ensures that the surface of the scraper 310 remains moist, preventing the waste ink adhering to it from drying and solidifying. This makes cleaning the scraper 310 much easier later; it can be cleaned simply with water or a simple cleaning tool, greatly improving cleaning efficiency and reducing cleaning costs.

[0038] In some specific embodiments, the upper end of the movable seat 320 is provided with a first collection groove 321, and the scraper 310 is installed in the first collection groove 321 and extends out from the upper opening of the first collection groove 321. In actual use, when the scraper 310 scrapes the waste ink on the print head, due to the friction and adhesion between the scraper 310 and the waste ink, some waste ink will adhere to the scraper 310. At this time, the first collection groove 321 plays an important role. This part of the waste ink attached to the scraper 310 can fall smoothly into the first collection groove 321 under the action of gravity along the setting direction of the scraper 310. The first collection groove 321 can collect this part of waste ink in a concentrated manner, preventing the waste ink from dripping randomly.

[0039] By setting up a first collection tank 321 to collect waste ink adhering to the scraper 310, the splashing of waste ink can be further reduced. Without the first collection tank 321, waste ink adhering to the scraper 310 may splash everywhere during the movement of the scraper 310, not only polluting the surrounding environment but also potentially wetting and contaminating other components of the waste ink collection device. Now, with the collection function of the first collection tank 321, the waste ink is confined within the tank, greatly reducing the probability of waste ink splashing. At the same time, it also reduces the wetting and contamination of other components by waste ink, protecting the normal operation and service life of other components, thereby ensuring the reliability of the waste ink collection device in this embodiment during use, enabling it to stably perform its waste ink collection function for a long period of time.

[0040] In some specific embodiments, a first drain port 322 is provided at the lower end of one side of the first collection tank 321, and a second collection tank 110 corresponding to the first collection tank 321 is provided on the base 100. The upper opening of the second collection tank 110 is located below the first drain port 322, and a second drain port 111 is provided at the lower end of the second collection tank 110. Specifically, when the first drain port 322 moves with the movable seat 320, the opening of the second collection tank 110 covers the movement trajectory of the first drain port 322. When the first drain port 322 moves with the movable seat 320, the first drain port 322 is always located above the opening of the second collection tank 110, so as to discharge the waste ink flowing into the first collection tank 321 in a timely manner, thereby reducing the adhesion and solidification of waste ink on the surface of the scraper 310 and reducing the difficulty of subsequent cleaning of the scraper 310.

[0041] In some specific embodiments, multiple scrapers 310 are provided, and these scrapers 310 are arranged in a direction perpendicular to the direction in which the drive assembly 400 drives the scrapers 310 to move. Each scraper 310 is installed in the first collection groove 321 to increase the coverage area of ​​the waste ink scraped off the printhead by the scraper 310 each time, thereby improving the scraping efficiency of this embodiment.

[0042] In some specific embodiments, the drive assembly 400 includes a drive motor 410 and a transmission belt 420. The drive pulleys of the drive motor 410 and the transmission belt 420 are both mounted on the base 100. The drive motor 410 and the transmission pulley of the transmission belt 420 are in a transmission cooperation. The movable seat 320 is fixedly connected to the transmission belt 420 through a connector. The periodic forward and reverse rotation of the drive motor 410 drives the transmission pulley to rotate, which in turn drives the transmission belt 420 to drive the movable seat 320 to move back and forth in the horizontal direction, thereby realizing the smooth reciprocating motion of the scraper 310 and ensuring the scraping effect of waste ink on the printhead in this embodiment.

[0043] In some specific embodiments, the base 100 is provided with a guide rail 120, and the movable seat 320 is provided with a slider 323 corresponding to the guide rail 120. The slider 323 is fitted and cooperated with the guide rail 120. The driving component 400 can drive the slider 323 to move along the guiding direction of the guide rail 120 to guide the movement trajectory of the scraper 310 and ensure its ink scraping effect on the printhead.

[0044] In some specific embodiments, two guide rails 120 are provided, and the two guide rails 120 are symmetrically arranged on both sides of the collection hopper 200, which further improves the guiding effect on the movement of the movable seat 320 and the scraper 310, and at the same time provides support for the movement of the movable seat 320, ensuring the reliable movement of the movable seat 320.

[0045] like Figure 1 As shown, a protective shell 121 is provided above the guide slide rail 120 and the slider 323. The movable seat 320 is fixedly connected to the slider 323 by a bending member passing through the side of the protective shell 121. The protective shell 121 is used to protect the guide slide rail 120 from being stained by splashed ink and to ensure the reliable use of the guide slide rail 120.

[0046] In some specific embodiments, a photoelectric sensor 130 is provided on the side of the base 100 near the guide rail 120, and a sensor 324 corresponding to the photoelectric sensor 130 is provided on the movable seat 320. During actual operation, when the drive motor 410 moves the movable seat 320 along the guide rail 120 to perform a scraping operation, the sensor 324 moves along with the movable seat 320. When the sensor 324 moves with the movable seat 320 to the sensing area of ​​the photoelectric sensor 130, the photoelectric element inside the photoelectric sensor 130 quickly senses the presence of the sensor 324, thereby generating a corresponding electrical signal change. This change is identified as the signal indicating the passage of the sensor 324.

[0047] After the photoelectric sensor 130 detects the passing signal of the sensor 324, it immediately transmits the signal to the device's control system. The control system analyzes and processes the received signal, and accurately determines the current position information of the sensor 324 according to a pre-set program and algorithm, thereby achieving the positioning of the sensor 324. This positioning process is rapid and accurate, providing a reliable basis for subsequent control operations.

[0048] After positioning is complete, the control system sends a stop or reverse signal to the drive motor 410 based on the position information of the sensor 324. Upon receiving the signal, the drive motor 410 quickly stops or reverses, causing the movable seat 320 and the scraper 310 mounted on the movable seat 320 to stop moving. In this way, the movable seat 320 and the scraper 310 can accurately stop at the same position after each ink scraping operation.

[0049] This precise positioning and stopping mechanism offers numerous advantages. Firstly, it ensures that subsequent ink scraping operations are performed under consistent standards and conditions, guaranteeing stable and reliable results each time and improving the quality and efficiency of waste ink collection. Secondly, it enables the waste ink collection device of this embodiment to adapt to the demands of long-term cyclical operation, reducing potential malfunctions and errors caused by uncertain positions of the movable seat 320 and the scraper 310, extending the device's lifespan, reducing maintenance costs, and providing strong support for the continuity and stability of production.

[0050] In some specific embodiments, multiple splash guards 210 are provided in the vertical direction to facilitate multiple buffering of waste ink and further reduce the probability of waste ink splashing.

[0051] like Figure 2 As shown, in some specific embodiments, the bottom of the collection hopper 200 is conical, and a third drain port 220 is provided at the lowest point of the bottom of the collection hopper 200. When waste ink enters the collection hopper 200, due to the guiding effect of the conical bottom, the waste ink will quickly converge towards the lowest point of the bottom. As the waste ink continues to accumulate, eventually all the waste ink will concentrate near the third drain port 220. At this time, by opening the discharge valve connected to the third drain port 220 (if there is a relevant control device), the waste ink can be quickly discharged from the third drain port 220 under its own gravity.

[0052] This design ensures rapid processing of waste ink within the collection hopper 200. Compared to traditional flat-bottomed collection hoppers 200, where waste ink tends to accumulate in the corners, requiring more time and effort for cleaning and discharge, the conical bottom combined with the third drain port 220 at the lowest end allows for a more efficient and thorough discharge of waste ink. This significantly improves the overall efficiency and practicality of the waste ink collection device, meeting the need for timely waste ink processing in actual production.
