Description

Technical Field

[0001] This utility model relates to the field of inkjet printing equipment technology, and in particular to an automatic ink recovery device. Background Technology

[0002] In horizontal printing (e.g., direct printing on various object surfaces), printheads need to be cleaned before printing, after changing ink colors, or during routine maintenance. This cleaning process generates a significant amount of waste ink. Simultaneously, residual ink droplets easily accumulate at the bottom of the printhead during printing, requiring scraping and cleaning before and after printing, which also generates a small amount of waste ink. Current technologies typically use simple collection trays or absorbent materials to collect this waste ink, which has the following significant drawbacks: First, different colored inks are mixed during collection, causing serious cross-contamination and making recycling impossible; second, the collected waste ink is usually treated as hazardous waste, increasing costs and burdening the environment; finally, the collection process often relies on manual operation, which is inefficient and incomplete.

[0003] Therefore, the existing technology still has shortcomings and deficiencies. There is an urgent need in this field for a device that can effectively solve the problem of ink cross-contamination and realize the automatic sorting, recycling and reuse of waste ink, so as to save resources, protect the environment and reduce operating costs. Utility Model Content

[0004] The purpose of this invention is to provide an automatic ink recycling device that solves the technical problems of existing technologies that use simple collection trays or absorbent materials to collect waste ink generated during printing operations, which have many obvious defects.

[0029] 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.

[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] This invention provides an automatic ink recycling device. By configuring independent ink discharge holes 22 and ink receiving trays 241 for different printheads 5 or color areas, it achieves ink diversion and isolation, solves the problem of ink mixing and contamination of different colors, and lays the foundation for ink recycling and reuse. By integrating ink discharge valve 41 and pipeline connector 42, it realizes automatic recycling and reuse of various types of ink. This not only greatly reduces the waste of expensive ink and lowers production costs, but also significantly reduces the discharge of hazardous waste liquid, meeting the requirements of green manufacturing.

[0032] Please refer to this as well. Figures 1 to 6 The automatic ink recycling device provided by this utility model includes:

[0033] Supporting framework 1;

[0034] The scraping mechanism includes a scraper mounting plate 2 that is horizontally reciprocatingly mounted on a support frame 1 and a scraper 21 mounted on the scraper mounting plate 2. The scraper mounting plate 2 has an ink discharge hole 22 corresponding to the position of the print head 5 of the printer.

[0035] Drive mechanism 3 is used to drive scraper mounting plate 2 to move horizontally reciprocatingly;

[0036] The ink receiving mechanism includes multiple independent ink receiving slots 241 located below the scraper mounting plate 2 for receiving ink dripping through the ink discharge hole 22;

[0037] The recycling mechanism 4 includes an ink discharge valve 41 located at the bottom of the ink receiving tank 241 and a pipe connector 42 connected to the ink discharge valve 41. The pipe connector 42 is used to connect to an external conveying device to achieve directional ink recycling.

[0038] The support frame 1 is a sturdy rectangular frame assembled from aluminum alloy profiles using standard connectors such as angle brackets. It features a stable structure, lightweight construction, and ease of adjustment. The scraper mounting plate 2 has multiple sets of ink drainage holes 22 and scraper mounting holes 23 arranged in a matrix on its surface, according to the array layout of the printheads 5 of the horizontal printer above. The scraper 21 is mounted on the scraper mounting plate 2 through the aforementioned scraper mounting holes 23, its position ensuring it can scrape the bottom of the printheads 5. The scraper 21 can be made of EPDM rubber. The upper surface of the scraper mounting plate 2 and the inner surface of the ink collection tank 241 are coated, for example, with Teflon. This coating has excellent resistance to acid and alkali corrosion, effectively reduces ink adhesion, ensures good ink flow, facilitates thorough drainage to prevent corrosion, and enhances drainage performance.

[0039] Ink dripping from the ink discharge hole 22 on the scraper mounting plate 2 will fall directly into the corresponding ink receiving tray 241. Multiple ink receiving trays 241 are set independently, and each ink receiving tray 241 is specifically used to receive ink from the printhead 5 of a specific color or specific area.

[0040] When the printer issues a cleaning or scraping command, the drive mechanism 3 operates, causing the scraper mounting plate 2 and its scraper 21 to move horizontally, completing the scraping and cleaning action on the bottom of the printhead 5. In cleaning mode, the waste ink ejected from the printhead 5 falls directly into the corresponding ink collection tank 241 through the ink drain hole 22 directly below it. In scraping mode, the scraper 21 scrapes away residual ink droplets from the bottom of the printhead 5, and the scraped-off ink droplets also drip into the ink collection tank 241 below through the ink drain hole 22. All inks are temporarily stored separately in independent tanks. When it is necessary to recycle a certain color of ink, the operator only needs to connect the corresponding hose to the pipe connector 42 in the recycling mechanism 4, open the corresponding ink drain valve 41, and start the external pump connected to the pipe. This will automatically and accurately transport the ink collected in the ink collection tank 241 back to its source ink container.

[0041] This configuration, by providing independent ink drain holes 22 and ink collection trays 241 for different printheads 5 or color areas, achieves ink diversion and isolation, solves the problem of ink mixing and contamination, and lays the foundation for ink recycling and reuse. By integrating ink drain valve 41 and pipeline connector 42, it realizes automatic recycling and reuse of various inks, which not only significantly reduces the waste of expensive inks and lowers production costs, but also significantly reduces the discharge of hazardous waste liquids, meeting the requirements of green manufacturing.

[0042] In some embodiments, each ink collection slot 241 is respectively set to correspond to the ink discharge hole 22 in different areas on the scraper mounting plate 2, so as to realize the classified collection of ink.

[0043] Please refer to this as well. Figure 1 , Figure 2 and Figure 6 A plurality of receiving plates 24 are fixedly installed directly below the scraper mounting plate 2, and each receiving plate 24 has an elongated ink collection groove 241. The vertical projection of each ink collection groove 241 completely covers a row or a specific color zone of ink discharge holes 22 on the scraper mounting plate 2, ensuring that the ink dripping from the specific ink discharge hole 22 can fall accurately into the designated ink collection groove 241.

[0044] In some embodiments, a guide rail 11 is provided on the support frame 1, and a slider 25 is provided on the scraper mounting plate 2 to be slidably connected to the guide rail 11. The scraper mounting plate 2 is slidably mounted on the support frame 1 via the slider 25.

[0045] Please refer to this as well. Figure 1 , Figure 2 and Figure 4Two high-precision linear guide rails 11 are installed parallel to each other on the upper part of the support frame 1. Several sliders 25 are slidably connected to each guide rail 11. The scraper mounting plate 2 is fixedly connected to the top of these sliders 25 by bolts. Several sliders 25 are distributed at intervals on the bottom of the scraper mounting plate 2. When the drive mechanism 3 is working, it enables the entire scraper mounting plate 2 to slide smoothly horizontally along the axial direction of the guide rail 11.

[0046] In some embodiments, the drive mechanism 3 includes a drive cylinder 31 fixed to the support frame 1, and the piston rod of the drive cylinder 31 is connected to the scraper mounting plate 2 in a transmission manner.

[0047] Please refer to this as well. Figures 1 to 4 The drive cylinder 31 is mounted on the support frame 1 and is located between two guide rails 11. The piston rod of the drive cylinder 31 is connected to the middle of one side of the scraper mounting plate 2. When the piston rod of the drive cylinder 31 extends or retracts, the scraper mounting plate 2 slides smoothly horizontally along the guide rail 11 with the cooperation of the guide rail 11 and the slider 25.

[0048] In some embodiments, the drive mechanism 3 further includes a connecting block fixed to the scraper mounting plate 2 and a connecting plate 32 fixed to the support frame 1. The cylinder body of the drive cylinder 31 is fixed to the connecting plate 32, and the piston rod of the drive cylinder 31 is connected to the scraper mounting plate 2 through the connecting block.

[0049] Please refer to this as well. Figures 1 to 4 The drive mechanism 3 also includes two connecting blocks and a connecting plate 32. The connecting plate 32 is fixed to one side of the support frame 1 by bolts, and the cylinder body of the drive cylinder 31 is fixed to the connecting plate 32. The two connecting blocks are respectively fixed to both ends of the scraper mounting plate 2 by bolts, and one side of the connecting block is connected to the piston rod of the drive cylinder 31 by bolts, so as to realize the fixed installation of the drive cylinder 31 and ensure the stability of the structure.

[0050] In some embodiments, a buffer element is provided at the connection between the piston rod of the drive cylinder 31 and the connecting block.

[0051] A buffer element is installed at the connection between the piston rod of the drive cylinder 31 and the connecting block. By setting the buffer element, the impact when the drive cylinder 31 moves can be reduced.

[0052] In some embodiments, the cushioning element includes a shock-absorbing pad and / or a washer.

[0053] In this embodiment, the shock-absorbing pad can be a polyurethane shock-absorbing pad, and the washer can be a POM washer. The shock-absorbing pad and the washer can form a buffer structure to absorb impact and vibration, improve motion stability and reduce noise.

[0054] In some embodiments, a buffer 121 is provided on the support frame 1 to buffer and limit the movement of the scraper mounting plate 2.

[0055] Please refer to this as well. Figures 1 to 4 A mounting block 12 is fixed on the support frame 1 at each of the two extreme positions corresponding to the reciprocating motion of the scraper mounting plate 2. A buffer 121 is mounted on the mounting block 12. When the scraper mounting plate 2 moves to the two extreme positions under the drive of the drive cylinder 31, the side of the scraper mounting plate 2 will contact the contact of the buffer 121, thereby achieving smooth deceleration and stopping, effectively reducing noise and vibration.

[0056] In some embodiments, the buffer 121 is a hydraulic buffer.

[0057] In this embodiment, the buffer 121 is a hydraulic buffer. The hydraulic buffer can convert kinetic energy into heat energy and dissipate it through its internal precision holes and piston, which is efficient and stable. The damping effect of hydraulic pressure is a relatively smooth and continuous process, avoiding the violent impact sound of metal springs or the hard impact sound of rubber, thus achieving low-noise operation.

[0058] In some embodiments, the ink discharge valve 41 is a ball valve, and the pipe connector 42 is a quick-connect connector.

[0059] Please refer to this as well. Figure 1 , Figure 2 , Figure 5 and Figure 6 Each ink collection tank 241 has an internal threaded adapter 43 installed at its lowest point. The internal threaded adapter 43 is connected in sequence to an ink drain valve 41 and a pipe connector 42. In this embodiment, the ink drain valve 41 is a ball valve, and the pipe connector 42 is a quick-connect connector. When it is necessary to recover ink of a certain color, the operator only needs to insert the corresponding hose into the quick-connect connector, open the corresponding ink drain valve 41, and start the external pump connected to the above-mentioned hose pipeline. This will automatically and accurately transport the ink collected in the ink collection tank 241 back to its source ink container.

[0060] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0061] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
