Abstract
Description
Technical Field
[0001] This utility model relates to the field of inkjet printing, and in particular to a printhead detection and cleaning device and an inkjet equipment. Background Technology
[0002] Inkjet printing technology refers to the technology of spraying ink droplets from nozzles on a printhead onto a substrate to obtain images or text. Inkjet printing equipment is equipped with a printhead, which in turn has multiple nozzles. When the printhead is working, ink is ejected through the multiple nozzles to achieve the printing of the image.
[0003] However, after prolonged use, ink residue can remain near the nozzles. Once dried and hardened, this ink can clog the nozzles, causing some to malfunction and affecting print quality. Currently, cleaning devices, such as scrapers, are installed on the side of inkjet printers to remove residual ink from the printhead and prevent clogging. However, scraping alone cannot remove residual ink from inside the nozzles, leading to continued clogging. Therefore, a detection device, such as an ink shortage detector, is needed to trigger an alarm when nozzle clogging is detected, alerting staff to address the issue promptly.
[0004] Currently, in existing technologies, the doctor blade and ink failure detection device are usually set up independently, which takes up a lot of space in the inkjet equipment. Moreover, in terms of equipment maintenance, the doctor blade and ink failure detection device need to be adjusted separately to adjust their relative positional relationship with the printhead nozzles, which is difficult and time-consuming, resulting in high maintenance costs.

[0029] When a printhead operates for an extended period, some ink can remain near the nozzles. Once dried and hardened, this ink can clog the nozzles, preventing some nozzles from functioning properly and impacting print quality. Typically, a cleaning device 4, such as a scraper, is installed on the side of the inkjet printer to remove residual ink from the printhead 2 using a scraper blade 43, preventing clogging. However, the scraper blade 43 cannot completely remove residual ink from inside the nozzles, still leading to clogging. Therefore, a detection device 3 is needed to issue an alarm when nozzle clogging is detected, alerting staff to address the issue promptly.
[0030] Currently, in existing technologies, the cleaning device 4 and the detection device 3 are usually set up independently, occupying a lot of space in the inkjet equipment. Moreover, in terms of equipment maintenance, since the nozzle rows of the printhead 2 are set in different directions, if a doctor blade is used for cleaning, the doctor blade direction must be the same as the nozzle row direction to prevent ink from different nozzle rows from contaminating each other. On the other hand, the detection device 3 requires that the nozzle rows or nozzle columns of the printhead 2 pass above the detection device 3 to detect all nozzles. Therefore, if the doctor blade and the detection device are set up separately, the relative positional relationship between each device and the printhead 2 needs to be adjusted separately, resulting in high adjustment difficulty, long time, and high maintenance costs.
[0031] To address the aforementioned problems, in a first aspect, this utility model provides a printhead detection and cleaning device, comprising a support beam 1, at least one printhead 2, a detection device 3, and a cleaning device 4. The printhead 2 is movably mounted on the support beam 1 and can reciprocate along the support beam 1; the cleaning device 4 is fixedly mounted on the side end of the support beam 1; the detection device 3 is mounted on the cleaning device 4; when the printhead 2 moves, it can pass over the detection device 3 and the cleaning device 4, which are fixed together; the detection device 3 is used to detect whether the working state of the printhead 2 is abnormal; and the cleaning device 4 is used to clean the residual ink from the printhead 2.
[0032] Please see Figure 1-9 In this embodiment, the support beam 1 provides support for the print head 2 and the detection and cleaning device 4. The print head 2 is driven by a drive device to reciprocate along the support beam 1 in a second direction. The cleaning device 4 is fixedly installed on the left or right side of the support beam 1. Figure 1 The image shows a cleaning device 4 located on the right side of the support beam 1, and a detection device 3 mounted on top of the cleaning device 4. When the print head 2 moves along the support beam 1, it passes over both the detection device 3 and the cleaning device 4. By combining the detection device 3 and the cleaning device 4, space is saved in the inkjet equipment. The nozzle array direction of the print head 2 can be either a first direction or a second direction. With the nozzle array direction fixed, each nozzle can be inspected individually when passing through the detection device 3; and residual ink on the nozzle array can be cleaned when passing through the cleaning device 4. This reduces the difficulties, long debugging times, and high debugging costs associated with separating the detection device 3 and the cleaning device 4. It further improves the space utilization, cleaning and maintenance efficiency, and printing efficiency of the inkjet equipment.
[0033] Furthermore, the cleaning device 4 includes a scraping device, which includes a first receiving plate 41, a second receiving plate 42, and at least one scraper blade 43; the first receiving plate 41 is fixedly connected to the support beam 1; the second receiving plate 42 is movably disposed within the first receiving plate 41 and can reciprocate within the first receiving plate 41; the scraper blade 43 is used to scrape ink from the print head 2, and the scraping direction of the scraper blade 43 is the same as the nozzle column direction of the print head 2.
[0034] In this embodiment, the cleaning device 4 is configured as a scraping device, which uses scraper blades 43 to clean the residual ink from the printhead 2. The number of scraper blades 43 is related to the arrangement of the nozzles. The first storage plate 41 is fixedly connected to the support beam 1, providing space and support for other components of the scraping device. The first storage plate 41 is equipped with a slide rail 411, a conveyor belt 412, and a motor 413, with the motor 413 being driven by the conveyor belt 412. The second storage plate 42 is nested on the slide rail 411, and one end of the second storage plate 42 is connected to the conveyor belt 412. The second storage plate 42 reciprocates within the first storage plate 41, driven by the motor 413 and the conveyor belt 412. The scraping direction of the scraper blades 43 must be the same as the direction of the nozzle array of the printhead 2. This is because the ink ejected from different nozzle arrays may have different colors, and scraping along the direction of the nozzle array can prevent cross-contamination between different nozzle arrays. Both the first storage plate 41 and the second storage plate 42 are provided with flow guide holes 44 (the flow guide holes on the second storage plate 42 are not shown in the figure). Waste ink on the second storage plate 42 flows into the first storage plate 41 through the flow guide holes and is discharged uniformly through the flow guide holes 44 on the first storage plate 41.
[0035] Furthermore, the detection device 3 includes a laser ink breakage detection device, which includes a main body 31, and the main body 31 is fixedly connected to the cleaning device 4; a laser emitting part 32 and a laser receiving part 33 are fixedly provided at both ends of the main body 31.
[0036] In this embodiment, the detection device 3 is preferably a laser ink blockage detection device. A laser 34 is emitted by the laser emitter 32 and received by the laser receiver 33. When the nozzles of the printhead 2 are functioning normally, the ejected ink can block the laser 34 from reaching the laser receiver 33. However, when the nozzles are clogged, the laser 34 can reach the laser receiver 33. Upon receiving the laser 34, the laser receiver 33 promptly issues an alarm to remind the operator to address the printhead blockage and prevent it from affecting inkjet printing quality. Alternatively, the detection device 3 can also use other optical sensors (such as infrared) or electrical sensors (resistance, pressure) to detect nozzle blockage.
[0037] Example 1
[0038] Furthermore, the nozzle array direction of the print head 2 is the first direction; the second storage plate 42 can reciprocate within the first storage plate 41 along the first direction; the scraper 43 is disposed on the second storage plate 42; the laser ink breakage detection device is disposed on the side end of the first storage plate 41; and the laser emitting part 32 emits a laser 34 in the first direction.
[0039] Please see Figure 3-4 In this embodiment, the scraper 43 is disposed on the second receiving plate 42 and moves back and forth along the first direction with the second receiving plate 42. The scraping direction of the scraper 43 is also the first direction to ensure that the nozzle array is scraped. The line connecting the laser emitting unit 32 and the laser receiving unit 33 is the first direction. The laser ink breakage detection device is disposed on the side of the scraping device near the middle of the support beam 1. The laser ink breakage detection device can detect the nozzle array of the print head 2 one by one.
[0040] In use, the print head 2 moves along the support beam 1, first passing above the laser ink breakage detection device. Since the nozzle array is parallel to the emission direction of the laser 34, the laser ink breakage detection device detects each nozzle array as the print head 2 moves. After completing the ink breakage detection, the print head 2 stops moving when it is directly above the scraper device. At this time, the second receiving plate 42 drives the scraper 43 to move in the first direction to scrape ink from the surface of the print head 2.
[0041] Example 2
[0042] Furthermore, the nozzle array direction of the print head 2 is the first direction; the second storage plate 42 can reciprocate within the first storage plate 41 along the first direction; the scraper 43 and the laser ink breakage detection device are disposed on the second storage plate 42; the laser emitting part 32 emits laser 34 in the second direction.
[0043] Please see Figure 5 In this embodiment, unlike in Example 1, the laser ink breakage detection device and the scraper 43 are jointly disposed on the second storage plate 42. The movement of the second storage plate 42 can ensure that the laser ink breakage detection device can traverse the nozzle row; the line connecting the laser emitting part 32 and the laser receiving part 33 is the second direction, preferably the first direction is perpendicular to the second direction, that is, the laser 34 emission direction is perpendicular to the nozzle column and parallel to the nozzle row.
[0044] When in use, the print head 2 stops moving when it moves above the scraper device. The second storage plate 42 drives the scraper 43 and the laser ink breakage detection device to move in the first direction, thus completing the scraping of ink on the nozzle column and the detection of ink breakage on the nozzle row.
[0045] Example 3
[0046] Furthermore, the nozzle array direction of the print head 2 is the second direction; the second storage plate 42 can reciprocate within the first storage plate 41 along the second direction; the scraper 43 is disposed on the second storage plate 42; the laser ink breakage detection device is disposed on the side of the first storage plate 41 or on the second storage plate 42; the laser emitting part 32 emits a laser 34 in the first direction.
[0047] Please see Figure 6-7 In this embodiment, unlike Embodiments 1 and 2, the nozzle array direction faces the second direction, preferably with the first and second directions perpendicular. To match the nozzle array direction, the scraping direction of the scraper 43 is also the second direction. In this embodiment, the laser ink breakage detection device emits laser 34 towards the first direction, meaning the laser 34 emission direction is perpendicular to the nozzle array and parallel to the nozzle row. In this embodiment, the laser ink breakage detection device has two installation positions:
[0048] The first method involves installing the laser ink breakage detection device on one side of the first storage plate 41 near the middle of the support beam 1, such as... Figure 7 As shown, when the scraper is located on the left side of the support beam 1, a laser ink breakage detection device is installed in area b; when the scraper is located on the right side of the support beam 1, a laser ink breakage detection device is installed in area a. In use, the print head 2 moves along the support beam 1, first passing above the laser ink breakage detection device. Since the nozzle array is perpendicular to the laser 34 emission direction, the laser ink breakage detection device detects each nozzle row as the print head 2 moves. After completing the ink breakage detection, the print head 2 stops moving when it is directly above the scraper. At this time, the second receiving plate 42 drives the scraper blade 43 to move in the second direction to scrape the ink from the print head 2.
[0049] The second type is, such as Figure 7 As shown, the scraper 43 and the laser ink breakage detection device are both mounted on the second storage plate 42 and can move with the second storage plate 42 in the second direction. In use, the print head 2 stops moving when it moves above the scraper device along the support beam 1. The second storage plate 42 drives the scraper 43 and the laser ink breakage detection device to move in the second direction, simultaneously completing the scraping of ink in the nozzle column and the detection of ink breakage in the nozzle row.
[0050] Example 4
[0051] Furthermore, the nozzle array direction of the print head 2 is the second direction; the second storage plate 42 can reciprocate within the first storage plate 41 along the first direction; the scraper 43 is disposed on the first storage plate 41; the laser ink breakage detection device is disposed on the second storage plate 42; and the laser emitting part 32 emits a laser 34 in the second direction.
[0052] Please see Figure 8 In this embodiment, only a laser ink breakage detection device is provided on the second receiving plate 42. The laser ink breakage detection device is moved in the first direction by the second receiving plate 42, and the emission direction of the laser 34 is the second direction. Preferably, the first direction and the second direction are perpendicular. Since the direction of the nozzle array is the second direction, the scraper 43 is set on the side of the first receiving plate 41 near the middle of the support beam 1. Figure 8 The image shows the installation position of the scraper blade 43 when the scraper device is located on the right side of the support beam 1. In this embodiment, the scraper blade 43 is a double-sided scraper blade, which means that it can scrape ink from the nozzle array in two directions.
[0053] In use, the print head 2 moves along the support beam 1, first passing the scraper 43, and the first ink scraping is completed by the relative movement between the print head 2 and the scraper 43. When the print head 2 moves directly above the first storage plate 41, it stops moving, and the second storage plate 42 drives the laser ink breakage detection device to move in the first direction to detect each column of nozzles. After the ink breakage detection is completed, the print head 2 moves along the support beam 1 away from above the first storage plate 41. During the movement of the print head 2, it passes the scraper 43 again, and the second ink scraping is completed by the relative movement between the print head 2 and the scraper 43.
[0054] Example 5
[0055] Furthermore, the cleaning device 4 includes a negative pressure adsorption cleaning device, which includes a first storage plate 41 and an adsorption tank 45; the first storage plate 41 is fixedly connected to the support beam 1; the adsorption tank 45 is disposed on the upper end of the first storage plate 41 and is airtightly connected to the first storage plate 41; the adsorption area of the adsorption tank 45 matches the print head 2; the laser ink breakage detection device is disposed on the side end of the first storage plate 41; the laser emitting part 32 emits a laser 34 in a first direction.
[0056] Please see Figure 9 In this embodiment, the cleaning device 4 is a negative pressure adsorption cleaning device. Through negative pressure adsorption, it removes residual ink from the surface of the print head 2 and inside the nozzles, further preventing the nozzles from being clogged by residual ink. The adsorption tank 45 is airtightly connected to the first receiving plate 41, transferring the adsorption force of the first receiving plate 41 to the adsorption tank 45. When the print head 2 moves above the cleaning device 4, the print head 2 should be sized to match the adsorption tank 45 to ensure that the nozzles of the print head 2 are evenly subjected to negative pressure adsorption. In this embodiment, the laser ink breakage detection device is located on the side of the first receiving plate 41 near the middle of the support beam 1. Figure 9The image shows the location of the laser ink breakage detection device when the negative pressure adsorption cleaning device is installed on the right side of the support beam 1. The laser 34 emitting end emits laser 34 in the first direction.
[0057] In use, the print head 2 moves along the support beam 1, first passing through the laser ink breakage detection device, which detects each nozzle column or row. When the print head 2 moves directly above the cleaning device 4, it stops moving, and the suction tank 45 performs negative pressure suction cleaning on the print head 2. This embodiment does not use a scraper to scrape ink, and there are no requirements on the arrangement direction of the nozzle column, making it more adaptable.
[0058] Example 6
[0059] Secondly, this utility model provides an inkjet device, including a printing platform and the printhead detection and cleaning device described in the first aspect, wherein the printing platform is located below the printhead 2.
[0060] In this embodiment, the inkjet device includes a printing platform, and the print head 2 moves above the printing platform to perform inkjet printing on the substrate on the printing platform. Some inkjet devices also include, but are not limited to, a transport mechanism and a curing mechanism. The transport mechanism is used to transport the substrate; the curing mechanism is used to cure and dry the substrate after inkjet printing.
[0061] In summary, the beneficial effects of this utility model are as follows: By fixing the detection device and the cleaning device together, the printhead can perform both ink breakage detection and printhead cleaning when it moves above the detection and cleaning device. This reduces the debugging time and the inability to perform detection and cleaning in a centralized manner when the detection and cleaning devices are set up separately, thus improving the efficiency of detection and cleaning. Secondly, the detection and cleaning device of this utility model is simple to debug and has low maintenance costs. Furthermore, setting the detection device and the cleaning device together can reduce the space occupied by the inkjet equipment, providing more space for the installation of other components in the inkjet equipment.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
