[0035] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0036] In a first aspect, please refer to Figure 1 and Figure 2 , the embodiments of the present application provide an ink scraping assembly 100. In the prior art, the printing nozzle is usually arranged downward, that is, the printing nozzle prints on the printing medium below. In the embodiments of the present application, the ink scraping assembly 100 is arranged below the printing nozzle, and the ink scraping assembly 100 moves up and down relative to the printing nozzle to approach or move away from the printing nozzle as an example for illustration. It can be understood that in other embodiments of the present application, the ink scraping assembly 100 can also move in other directions to approach or move away from the printing nozzle. In the embodiments of the present application, the ink scraping assembly 100 is used to scrape the liquid of the printing nozzle, and this liquid is mainly ink, so the embodiments of the present application take the liquid as ink as an example for illustration; it can be understood that in some other embodiments of the present application, the liquid can also be other liquids, such as a mixture of ink and water, a mixture of ink and dust, or a mixture of ink and lubricating oil, etc.

[0037] For the above-mentioned ink scraping assembly 100, please refer to Figure 1 and Figure 2, the ink scraping assembly 100 includes a mounting plate 1 and an ink scraping blade 2. The mounting plate 1 can be in the shape of a rectangular plate and can be horizontally arranged, and the ink scraping blade 2 can be in the shape of a rectangular sheet. The mounting plate 1 can be arranged on the lifting drive assembly, and the ink scraping blade 2 is arranged on the mounting plate 1. The ink scraping blade 2 is used to scrape the ink on the bottom surface of the print head. The mounting plate 1 and the ink scraping blade 2 can move up and down synchronously with the lifting drive assembly, so that the ink scraping blade 2 approaches and contacts the print head. After the ink scraping blade 2 contacts the print head, the print head moves horizontally relative to the ink scraping blade 2, so that the ink scraping blade 2 scrapes away the ink of the print head. The horizontal movement of the print head relative to the ink scraping blade 2 can be achieved by driving the print head to move horizontally by the printer, or by driving the ink scraping assembly 100 to move horizontally. It can be understood that the contact surface between the ink scraping blade 2 and the print head is usually in a linear shape. When the ink scraping blade 2 moves horizontally relative to the print head, the moving direction of the ink scraping blade 2 is perpendicular to the line, so as to maximize the ink scraping area of the ink scraping blade 2.

[0038] Among them, please refer to Figure 1 and Figure 2 , the number of the ink scraping blades 2 is multiple, and the position of each ink scraping blade 2 corresponds to the position of a print head up and down, that is, when observing along the up and down direction, the projection of each ink scraping blade 2 at least partially coincides with the projection of a print head. Therefore, the ink scraping assembly 100 can scrape the ink of multiple print heads at the same time, improving the ink scraping efficiency. The number of the ink scraping blades 2 can be one-half, one-third, one-fourth, etc. of the total number of print heads on the printer. The ink scraping assembly 100 performs zoned ink scraping on the print heads of the printer and scrapes each zone one by one; the number of the ink scraping blades 2 can also be equal to the total number of print heads on the printer, and the ink scraping assembly 100 can complete ink scraping on all the print heads of the printer at the same time. Optionally, the multiple ink scraping blades 2 are arranged in a "pin" shape.

[0039] In some embodiments, please refer to Figure 1 and Figure 2 , a through liquid leakage hole 11 is provided at the bottom of the mounting plate 1. After the ink scraping blade 2 scrapes the ink of the print head, the ink flows downward along the ink scraping blade 2 to the bottom of the mounting plate 1 and can flow out of the mounting plate 1 downward through the liquid leakage hole 11 to improve the problem of ink accumulation in the mounting plate 1. Among them, the number of the liquid leakage holes 11 can be multiple, and the size of the liquid leakage holes 11 can be much larger than the size of the ink scraping blade 2, so that the bottom of the mounting plate 1 has good liquid and gas permeability, increasing the efficiency of the ink leaking out of the mounting plate 1 through the liquid leakage holes 11, and the ink can also be blown out of the mounting plate 1 through the gas from the liquid leakage holes 11.

[0040] It should be noted that when the ink scraping assembly 100 rises to contact the printing nozzle, the ink scraping blade 2 is in hard contact with the printing nozzle. For example, the ink scraping blade 2 eats into the printing nozzle about 1 mm from the side of the printing nozzle. Subsequently, when the ink scraping blade 2 scrapes the ink, the ink scraping blade 2 will pass through the sharp position at the edge of the starting point of the printing nozzle, resulting in physical damage to the ink scraping blade 2 after a few days of use, such as severe wear, and even grooves and notches. The physically damaged ink scraping blade 2 cannot be used continuously and can only be scrapped, that is, the service life of the ink scraping blade 2 is short, increasing the use cost of the ink scraping blade 2. The ink scraping blade 2 is also likely to scratch the surface of the printing nozzle, shortening the service lives of the printing nozzle and the ink scraping blade 2. To improve this deficiency, in some embodiments, please refer to Figure 1 and Figure 2 , the ink scraping assembly 100 further includes an elastic sheet 3. The elastic sheet 3 connects the ink scraping blade 2 to the mounting plate 1. For example, one end of the elastic sheet 3 is connected to the mounting plate 1, and the other end of the elastic sheet 3 is connected to the ink scraping blade 2. The elastic sheet 3 can be a metal sheet, such as a steel sheet or a copper sheet, and has good elasticity. The elastic sheet 3 is used to deform when the ink scraping blade 2 contacts the printing nozzle. For example, when the ink scraping blade 2 contacts the printing nozzle, the reaction force of the printing nozzle on the ink scraping blade 2 drives the elastic sheet 3 to bend, so that the pressure between the ink scraping blade 2 and the printing nozzle is proportional to the bending degree of the elastic sheet 3, improving the problem of severe wear caused by the hard contact between the ink scraping blade 2 and the printing nozzle and extending the service lives of the ink scraping blade 2 and the printing nozzle. Moreover, when the ink scraping blade 2 eats into the printing nozzle about 1 mm from the side of the printing nozzle and scrapes the ink, the ink scraping blade 2 will pass through the sharp position at the edge of the starting point of the printing nozzle. However, since the elastic sheet 3 connects the ink scraping blade 2 to the mounting plate 1, the reaction force of the printing nozzle on the ink scraping blade 2 will drive the elastic sheet 3 to bend, so that the whole ink scraping blade 2 moves away from the printing nozzle until the ink scraping blade 2 contacts the bottom surface of the printing nozzle. In this way, the damage to the ink scraping blade 2 caused by the sharp position at the edge of the starting point of the printing nozzle can be reduced, and the service life of the ink scraping blade 2 can be extended.

[0041] Particularly, since the elastic sheet 3 connects the blade 2 to the mounting disk 1, when the blade 2 moves upward to contact the print head, the relative position of the blade 2 and the print head in the horizontal direction can be controlled so that the blade 2 directly contacts the bottom surface of the print head. Subsequently, the print head is controlled to move horizontally relative to the blade 2 to achieve ink scraping. If the blade 2 moves horizontally outside the print head, that is, when viewed in the vertical direction, there is a gap between the blade 2 and the print head, then the blade 2 is controlled to descend, and then the above steps of the blade 2 contacting the print head are repeated. By making the blade 2 directly contact the bottom surface of the print head and making the blade 2 contact the bottom surface of the print head again when the blade 2 moves horizontally outside the print head, the situation where the sharp position at the starting point of the print head contacts the blade 2 can be directly avoided, the damage to the blade 2 caused by the sharp position at the starting point of the print head can be reduced, the service life of the blade 2 can be extended, and the problem that the blade 2 adheres ink to the side of the print head, making it difficult to clean the ink, can be improved.

[0042] The elastic sheet 3 can be directly connected to the mounting disk 1 and the blade 2 by screws or bolts, or can be indirectly connected through some parts. For example, in some embodiments, referring to FIGS. 1 and Figure 2 , the blade assembly 100 further includes a first mounting block 4 and a second mounting block 5. The first mounting block 4 is disposed on the mounting disk 1. Two ends of the elastic sheet 3 are respectively connected to the first mounting block 4 and the second mounting block 5, and the blade 2 is disposed on the second mounting block 5. The first mounting block 4 is connected to the mounting disk 1 and the elastic sheet 3 by screws or bolts, and the second mounting block 5 is connected to the elastic sheet 3 and the blade 2 by screws or bolts.

[0043] Among them, referring to Figure 1 and Figure 2 , along the direction parallel to the mounting disk 1, the first mounting block 4 and the second mounting block 5 are spaced apart; along the direction perpendicular to the mounting disk 1, the second mounting block 5 and the mounting disk 1 are spaced apart. Since the first mounting block 4 and the second mounting block 5 are spaced apart along the direction parallel to the mounting disk 1, the first mounting block 4 does not affect the movement of the second mounting block 5 in the direction perpendicular to the mounting disk 1, and the second mounting block 5 is spaced apart from the mounting disk 1, so that when the blade 2 contacts the print head, the second mounting block 5 can move closer to the mounting disk 1 and bend the elastic sheet 3. Optionally, the elastic sheet 3 is parallel to the mounting disk 1.

[0044] In some embodiments, referring to Figure 1 and Figure 2, when viewed in a direction perpendicular to the mounting plate 1, the projection of the ink scraper 2 coincides with the projection of the leakage hole 11. Since the first mounting block 4 is spaced from the second mounting block 5, the second mounting block 5 extends relative to the first mounting block 4 in a direction parallel to the mounting plate 1, and the second mounting block 5 can extend to the top of the leakage hole 11, thereby mounting the ink scraper 2 above the leakage hole 11. The ink on the ink scraper 2 will flow to the leakage hole 11 and leave the mounting plate 1 from the leakage hole 11, reducing the ink adhering to the inner wall of the mounting plate 1 and improving the efficiency of the ink leaving the mounting plate 1.

[0045] In some embodiments, see Figure 2 and Figure 3 The second mounting block 5 includes a mounting base 51 and a mounting platform 52. The mounting base 51 is connected to the elastic sheet 3. The mounting platform 52 is arranged on the side of the mounting base 51 away from the mounting plate 1. The ink scraping blade 2 is arranged on the mounting platform 52. The ink scraping blade 2 is mounted on the mounting platform 52, so that the ink scraping blade 2 can be installed upright, for example, the ink scraping blade 2 is at a right angle or an acute angle to the mounting plate 1. In the embodiment of the present application, please refer to Figure 2 and Figure 3 The mounting platform 52 is ridge-shaped, that is, the mounting platform 52 is in the shape of a lying triangular column, and the ink scraper 2 is installed on one side of the mounting platform 52, so there is an acute angle between the ink scraper 2 and the mounting plate 1. When the ink scraper 2 contacts the print head, there is also an acute angle between the ink scraper 2 and the print head.

[0046] In some embodiments, see Figure 2 and Figure 3 , the angle between the side of the scraper blade 2 facing the scraping direction and the mounting plate 1 is an obtuse angle, that is, the angle between the side of the scraper blade 2 facing the scraping direction and the print head is an acute angle. Among them, when the scraper blade 2 scrapes ink on the print head, the direction in which the scraper blade 2 moves relative to the print head is the scraping direction. The scraping direction is usually unique, that is, the scraper blade 2 only moves in one direction when scraping ink on the print head, so as to improve the problem of unclean scraping caused by the scraper blade 2 scraping ink back and forth. By making the angle between the side of the scraper blade 2 facing the scraping direction and the print head an acute angle, the friction between the print head and the scraper blade 2 can be reduced, the damage to the print head and the scraper blade 2 can be reduced, and the service life of the print head and the scraper blade 2 can be extended.

[0047] In some embodiments, see Figure 2 and Figure 3, an arc-shaped tip 21 is provided at one end of the squeegee blade 2 facing away from the mounting plate 1. The angle between the arc-shaped tip 21 and the other part of the squeegee blade 2 is an obtuse angle, and the angle between the side of the arc-shaped tip 21 facing the ink scraping direction and the mounting plate 1 is an acute angle, that is, the angle between the side of the arc-shaped tip 21 facing the ink scraping direction and the printing nozzle is an obtuse angle. When the arc-shaped tip 21 scrapes the ink of the printing nozzle, the arc-shaped tip 21 is similar to shoveling up the ink of the printing nozzle, which can make the ink gradually slide away from the printing nozzle along the arc-shaped tip 21, making it easier for the ink to separate from the printing nozzle.

[0048] In some embodiments, please refer to Figure 2 and Figure 3 , a through hole 511 is formed in the second mounting block 5. The through hole 511 can be specifically formed in the mounting base 51. The through hole 511 is located between the squeegee blade 2 and the mounting plate 1. The ink on the squeegee blade 2 will flow to the upper part of the second mounting block 5 and can flow through the through hole 511 to the liquid leakage hole 11 below the second mounting block 5, reducing the accumulation of ink above the second mounting block 5 and improving the efficiency of the ink leaving the squeegee assembly 100. Further, please refer to Figure 3 , when observing in a direction perpendicular to the mounting plate 1, the projection of the through hole 511 coincides with the projection of the liquid leakage hole 11. Therefore, the ink can directly enter the liquid leakage hole 11 after passing through the through hole 511, improving the efficiency of the ink leaving the squeegee assembly 100.

[0049] In some embodiments, please refer to Figure 3 , a diversion groove 512 is provided on one side of the mounting base 51 facing away from the mounting plate 1. The diversion groove 512 is provided adjacent to the bottom of the mounting table 52. For example, the diversion groove 512 is located at the connection between the mounting table 52 and the mounting base 51. The diversion groove 512 is communicated with the through hole 511. When the ink flows to the bottom of the mounting table 52, the ink will flow into the diversion groove 512 and flow into the through hole 511 under the guiding action of the diversion groove 512, reducing the accumulation of ink on the mounting base 51 and improving the efficiency of the ink leaving the squeegee assembly 100.

[0050] In some embodiments, please refer to Figure 2 , at least one squeegee blade 2 is close to the edge of the mounting plate 1, and it is not suitable to form a liquid leakage hole 11 below it, so that the ink is likely to accumulate at the position of the mounting plate 1 below the squeegee blade 2, and the ink is too far from the liquid leakage hole 11 to flow out from the liquid leakage hole 11. To improve this deficiency, in some embodiments, please refer to Figure 2 and Figure 4, at least one second mounting block 5 includes a baffle 53. The baffle 53 is disposed on a side of the mounting base 51 away from the mounting disc 1. The baffle 53 surrounds the mounting table 52. A notch 531 is formed on a side of the mounting table 52 away from the edge of the mounting disc 1. The squeegee 2 is disposed on the mounting table 52, that is, the baffle 53 surrounds one end of the squeegee 2 adjacent to the mounting base 51. When blowing air or spraying water on the squeegee 2, the ink will splash onto one end of the squeegee 2 adjacent to the mounting base 51 and the mounting table 52. The baffle 53 surrounds the mounting table 52, and a notch 531 is formed on a side of the mounting table 52 away from the edge of the mounting disc 1. Therefore, the ink can be guided towards the adjacent liquid leakage hole 11, and thus the ink can be guided in a direction away from the edge of the mounting disc 1, reducing the ink from splashing onto the edge of the mounting disc 1 or flying out of the mounting disc 1 above the mounting disc 1, improving the problem that the ink adhering to the edge of the mounting disc 1 is not easy to clean, and improving the problem that the ink flying outside the mounting disc 1 pollutes the printing environment. It can be understood that the notch 531 faces the adjacent other squeegee 2, so the ink can be guided towards the liquid leakage hole 11 corresponding to the adjacent other squeegee 2, improving the problem that the ink is too far away from the liquid leakage hole 11 and difficult to flow out from the liquid leakage hole 11.

[0051] For the above-mentioned baffle 53, please refer to Figure 4 , the baffle 53 includes a first wall 532 and a second wall 533. The first wall 532 is located on a side of the mounting table 52 away from the notch 531. The number of the second walls 533 is two. The two second walls 533 are respectively connected to two ends of the first wall 532, and both of the two second walls 533 are perpendicular to the first wall 532, thereby surrounding and forming a semi-surrounding baffle 53. Among them, the first wall 532 can be integrally formed on the mounting base 51; the second wall 533 can be detachably connected to the mounting base 51. For example, the second wall 533 is a metal plate, and the second wall 533 can be an iron sheet, a copper sheet, etc.

[0052] In a second aspect, an embodiment of the present application provides a printer (not shown). The printer includes a squeegee assembly 100. The printer has the structural features and beneficial effects of the squeegee assembly 100, which will not be elaborated here. Among them, the printer can be a flatbed printer, such as a UV (Ultraviolet LED Inkjet Printer) printer.

[0053] The ink scraping assembly 100 and the printer according to the embodiments of the present application. The elastic sheet 3 connects the ink scraping sheet 2 and the mounting disc 1, improving the problem that the ink scraping sheet 2 is severely worn due to hard contact with the print head, and reducing the damage to the ink scraping sheet 2 at the sharp position of the starting point edge of the print head, thereby prolonging the service life of the ink scraping sheet 2 and the print head. A through liquid leakage hole 11 is provided at the bottom of the mounting disc 1. When observing in the direction perpendicular to the mounting disc 1, the projection of the ink scraping sheet 2 coincides with the projection of the liquid leakage hole 11, and the projection of the through hole 511 coincides with the projection of the liquid leakage hole 11, improving the efficiency of the ink leaving the ink scraping assembly 100. The baffle 53 can reduce the ink from splashing to the edge of the mounting disc 1 or flying out of the mounting disc 1, and can also guide the ink towards the direction of the liquid leakage hole 11 corresponding to another adjacent ink scraping sheet 2, improving the problems of ink polluting the printing environment and being difficult to flow out of the liquid leakage hole 11.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit them; under the idea of the present application, the technical features in the above embodiments or different embodiments can also be combined, and the steps can be implemented in any order, and there are many other changes in different aspects of the present application as described above. For the sake of simplicity, they are not provided in detail; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
