[0034] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0035] See also Figures 1 to 6 The inkjet printing machine inkjet structure provided in this embodiment is applied to the inkjet printing machine, and specifically includes an inkjet assembly 100, a cleaning mechanism 200 and a displacement mechanism.

[0036] The inkjet assembly 100 includes a mounting plate 110 and a plurality of nozzles 120 . The plurality of nozzles 120 are disposed on the mounting plate 110 along a first direction and are arranged into a nozzle group.

[0037] Combination Figure 3 , Figure 4The cleaning mechanism 200 is disposed on one side of the inkjet assembly 100. The cleaning mechanism 200 includes a plurality of cleaning units 210. The plurality of cleaning units 210 are arranged at intervals along the first direction and staggered in the second direction, so that the cleaning areas of any two adjacent cleaning units 210 in the first direction overlap in the second direction. The total length of the plurality of cleaning units 210 in the first direction is greater than the length of the mounting plate 110 in the first direction. The displacement mechanism is in transmission connection with the inkjet assembly 100 or the cleaning mechanism 200. And the driving direction of the displacement mechanism is the same as the second direction.

[0038] Among them, in order to facilitate understanding of the setting location, Figure 3 The a direction is the first direction, the b direction is the second direction, and the first direction and the second direction are perpendicular to each other in the same horizontal plane.

[0039] To ensure that the spray pressure of the nozzle 120 can achieve thorough cleaning during the cleaning process, a plurality of independent cleaning units 210 are used to form a cleaning mechanism 200 in this embodiment. Compared with the large-area cleaning unit 210 with a larger cleaning range, the spray pressure of the plurality of small-area independent cleaning units 210 is greater and the cleaning effect is better.

[0040] However, in the structure of multiple small-area independent cleaning units 210, water stains are likely to remain on the mounting plate 110 at positions corresponding to the edges of the cleaning units 210 after cleaning.

[0041] In this embodiment, since the total length of the plurality of cleaning units 210 in the first direction is greater than or equal to the length of the mounting plate 110 in the first direction, it is possible to fully clean the mounting plate 110. Specifically, during cleaning, the cleaning unit 210 located at the front end first contacts the mounting plate 110 and the nozzle 120 and cleans the area, and the displacement mechanism is continuously driven so that the cleaning units 210 that subsequently contact the mounting plate 110 contact the remaining areas on the mounting plate 110 in sequence, thereby fully cleaning the mounting plate 110.

[0042] Furthermore, since the cleaning areas of any two adjacent cleaning units 210 in the first direction overlap in the second direction, the subsequent unit can remove the water stains remaining on the edge of the cleaning unit 210 that first contacted the mounting plate 110 after cleaning. The cleaning efficiency is high and the cleaning is relatively thorough, and it is not easy to leave any traces.

[0043] In this embodiment, the cleaning unit 210 includes a spray assembly 220 and a suction assembly 230. The spray assembly 220 is used to spray the cleaning liquid to the nozzle 120. The suction assembly 230 is used to suck the cleaning liquid on the surface of the nozzle 120. The spray assembly 220 and the suction assembly 230 are arranged at intervals along the moving direction of the displacement mechanism.

[0044] Specifically, the spray assembly 220 can spray cleaning liquid onto the surface of the nozzle 120 and the mounting plate 110. In this embodiment, the spray assembly 220 includes a plurality of small-area spray units, and each cleaning unit 210 is provided with a separate spray unit to achieve spray cleaning of the area corresponding to the cleaning unit 210.

[0045] Moreover, in this embodiment, each individual spray unit can be connected to a separate pump body to achieve pressurized spraying. Compared with the large-area spray structure, the small-area individual spray unit can further ensure the cleaning pressure of the spraying washing liquid to ensure the spray cleaning effect and more thorough cleaning.

[0046] Similarly, in this embodiment, the suction assembly 230 is arranged behind the spray assembly 220 along the moving direction of the displacement mechanism. Under this structure, the suction assembly 230 contacts the inkjet assembly 100 after the spray assembly 220 sprays. The suction assembly 230 is connected to a negative pressure device such as a negative pressure pump, so that the suction assembly 230 can remove the residual liquid in the corresponding area by suction through negative pressure. The washing liquid remaining on the mounting plate 110 and the nozzle after spray cleaning is sucked into the suction assembly 230 under the suction force generated by the negative pressure, so as to avoid residual washing liquid.

[0047] In this embodiment, a wiper 240 is provided on one side of the suction assembly 230 away from the spray assembly 220. The wiper 240 is higher than the suction assembly 230 and is used to abut against the bottom surface of the mounting plate 110 to scrape off the residual washing liquid on the spray head 120.

[0048] The wiper member 240 is arranged on a side of the suction assembly 230 away from the spray assembly 220. After the spray assembly 220 cleans the mounting plate 110 and the nozzle by spraying cleaning liquid, the suction assembly 230 performs suction to remove the residual cleaning liquid. The wiper member 240 contacts and abuts against the mounting plate 110, and scrapes off the cleaning liquid adsorbed on the mounting plate 110 at the rear of the suction assembly 230 so that the suction assembly 230 can inhale it. Compared with separate cleaning and suction, the wiper member 240 can further enhance the cleaning effect of the cleaning liquid, thereby making the cleaning effect of the inkjet assembly 100 even better.

[0049] In this embodiment, the spray assembly 220 includes a plurality of spray holes 221. The spray holes 221 are used to spray the washing liquid, and the plurality of spray holes 221 are arranged at intervals along the first direction.

[0050] Specifically, in this embodiment, each cleaning unit 210 is provided with a plurality of spray holes 221, and the cleaning length of the spray holes 221 in the plurality of cleaning units 210 in the first direction is the same as the length of the mounting plate 110 in the first direction. Under this structure, the inkjet assembly 100 and the cleaning mechanism 200 move relative to each other so that all the spray holes 221 can achieve comprehensive spray cleaning of the side of the mounting plate 110 opposite to the cleaning mechanism 200.

[0051] Similarly, in this embodiment, the suction assembly 230 includes a plurality of suction holes 231. The suction holes 231 are used to suck the residual washing liquid, and the plurality of suction holes 231 are arranged at intervals along the first direction.

[0052] Similar to the structure of the spray hole 221, in this embodiment, each cleaning unit 210 is provided with a suction hole 231, and the suction holes 231 in the plurality of cleaning units 210 are formed in the first direction at the suction area of ​​the mounting plate 110 with the same length in the first direction. When the displacement mechanism drives the inkjet assembly 100 and the cleaning mechanism 200 to move relative to each other, the plurality of suction holes 231 can fully suction and clean the side of the mounting plate 110 opposite to the cleaning mechanism 200.

[0053] The suction hole 231 in this embodiment is disposed in the tank body, and the opening height of the suction hole 231 is lower than the height of the wiper 240, so as to avoid the suction hole 231 and the mounting plate 110 being too close to each other and causing adsorption, thereby affecting the suction effect. In addition, under this structure, it is convenient for the wiper 240 to scrape the washing liquid into the tank body, so as to facilitate the suction of the suction hole 231.

[0054] And, specifically, the displacement mechanism in this embodiment includes a driving motor and a screw assembly extending in the horizontal direction. After the driving end of the driving motor is connected to the screw assembly, the screw assembly is connected to the inkjet assembly 100 to drive the inkjet assembly 100 to move in the second direction. During the movement of the inkjet assembly 100, it passes through the top of the spray assembly 220, the top of the wiper 240, and the top of the suction assembly 230 in sequence, and respectively realizes the effects of spraying and cleaning the mounting plate 110 and the nozzle, scraping off the washing liquid, and sucking the residual washing liquid, thereby realizing automatic cleaning of the inkjet assembly 100.

[0055] In this embodiment, the cleaning mechanism 200 further includes a moisturizing tank 250 and a height adjustment component. The moisturizing tank 250 is disposed on a side of the suction component 230 away from the spray component 220, and the moisturizing tank 250 is used to hold moisturizing liquid. The height adjustment component is connected to the moisturizing tank 250 in a transmission manner.

[0056] Please combine Figure 1 , Figure 2 ,in, Figure 1 The position of the inkjet assembly 100 before cleaning, Figure 2The inkjet assembly 100 is in a state after being cleaned and located above the moisturizing groove 250 .

[0057] After the nozzle of the inkjet assembly 100 and the mounting plate 110 are cleaned, the inkjet assembly 100 is moved to the top of the moisturizing groove 250. At this time, the position of the moisturizing groove 250 is opposite to the position of the mounting plate 110. The moisturizing groove 250 contains moisturizing liquid such as water. The distance between the moisturizing liquid in the moisturizing groove 250 and the mounting plate 110 is small, so as to realize the moisturizing maintenance of the nozzle. The moving end of the height adjustment assembly is transmission-connected to the moisturizing groove 250.

[0058] The height adjustment component can adjust the height of the moisturizing groove 250, so that the moisturizing groove 250 and the cleaning component can be moved up or down to moisturize the nozzle group.

[0059] Specifically, in this embodiment, the shape of the groove of the moisturizing groove 250 is similar to the shape of the mounting plate 110 and the area of ​​the groove of the moisturizing groove 250 is larger than the bottom area of ​​the mounting plate 110. Under this structure, the mounting plate 110 can extend into the moisturizing groove 250 along the groove of the moisturizing groove 250, so that the nozzle can be further attached to the moisturizing liquid in the moisturizing groove 250.

[0060] Among them, a sealing member convex toward the inside and outside of the groove is provided on the top inner wall of the moisturizing groove 250 in this embodiment. The sealing member is arranged on the inner wall of the moisturizing groove 250 along the circumference of the moisturizing groove 250, and the liquid level of the moisturizing liquid in the moisturizing groove 250 is below the top surface of the sealing member.

[0061] Under this structure, after the inkjet assembly 100 moves to the maintenance space, the moisturizing groove 250 moves upward under the action of the height adjustment assembly, so that the mounting plate 110 can enter the moisturizing groove 250, and the mounting plate 110 abuts and fits against the seal, so that the nozzle in the mounting hole forms a closed space with the moisturizing liquid in the moisturizing groove 250, thereby achieving moisturizing of the nozzle, and the moisturizing effect is very excellent.

[0062] In this embodiment, there are multiple nozzle groups, which are arranged in sequence on the mounting plate 110 along the moving direction of the displacement mechanism.

[0063] The plurality of nozzle groups can realize multiple inkjet actions on the substrate, thereby ensuring the effect and quality of inkjet printing. The plurality of nozzle groups are sequentially arranged on the mounting plate 110 along the moving direction of the displacement mechanism, i.e., the second direction. When the displacement mechanism drives the inkjet assembly 100 to move, the plurality of nozzle groups can be cleaned.

[0064] In this embodiment, every two nozzle groups form an inkjet area. The multiple inkjet areas are staggered and alternately arranged on the plate along a direction perpendicular to the moving direction of the displacement mechanism.

[0065] The multiple inkjet areas arranged alternately can print on the substrate multiple times, and the staggered arrangement of the multiple inkjet areas can reduce the striping effect, improve the resolution to improve the printing quality, and can realize parallel printing, reduce the moving distance to increase the printing speed. At the same time, it can also disperse the workload of a single nozzle 120, reduce the wear and failure rate of a single nozzle 120, and extend the service life of the nozzle 120. Even if a nozzle 120 fails, the other nozzles 120 can still continue to work, reducing the downtime of the whole machine caused by the failure of a single nozzle 120.

[0066] Furthermore, in this embodiment, there are a plurality of cleaning units 210 and they are arranged in two columns along the second direction, and the cleaning units 210 in each column are arranged at intervals along the first direction to form a first unit group and a second unit group.

[0067] After the plurality of cleaning units 210 in the first unit group are arranged in a spaced manner along the first direction, a first gap exists between two adjacent cleaning units 210. The second unit group is arranged on one side of the first unit group, and each cleaning unit 210 in the second unit group is opposite to the position of the first gap, and the length of the cleaning unit 210 is greater than the length of the first gap. Similarly, a second gap exists between two adjacent cleaning units 210 in the second unit group, and the positions of the plurality of cleaning units 210 in the first unit group are opposite to the positions of the plurality of second gaps, and the length of the cleaning unit 210 is greater than the length of the second gap.

[0068] Under this structure, during the cleaning process, if the inkjet assembly 100 first contacts the first unit group, the cleaning unit 210 in the first unit group will first clean the inkjet assembly 100, which is likely to leave washing liquid or water stains in the area corresponding to the first gap of the mounting plate 110. The displacement assembly continues to drive the inkjet assembly 100 to move so that the second unit group cleans the inkjet assembly 100. During the cleaning process of the second assembly, each cleaning unit 210 in the second unit group can remove the washing liquid remaining on the mounting plate 110 in the first gap, thereby avoiding washing liquid residue on the mounting plate 110 and the nozzle.

[0069] If the inkjet assembly 100 contacts the second unit group first, the second unit group cleans the inkjet assembly 100 first, and removes the washing liquid and water stains remaining on the mounting plate 110 in the second gap when the first unit group cleans the inkjet assembly 100.

[0070] In this embodiment, the inkjet printing machine inkjet structure further includes an ink supply mechanism, and there are multiple ink supply mechanisms, which are connected to the multiple inkjet areas in a one-to-one correspondence.

[0071] Specifically, in this embodiment, the number of inkjet mechanisms is corresponding to the number of inkjet areas, and the multiple inkjet mechanisms are arranged in the same direction, and different colors of ink are stored in the multiple inkjet mechanisms to achieve multi-color spraying on the substrate.

[0072] In this embodiment, a mounting groove is provided on the mounting plate 110, and the nozzle 120 is provided in the mounting groove. The nozzle 120 has a nozzle. The nozzle is provided in the mounting groove, and the length of the nozzle is less than the thickness of the mounting groove.

[0073] Specifically, in this embodiment, the nozzle is arranged in the mounting groove to form an embedded structure on the mounting plate 110, and the length of the nozzle is less than the thickness of the mounting plate 110, so that the bottom end of the nozzle is located in the mounting groove. Under this structure, the nozzle does not need to be exposed outside the mounting plate 110, which can prevent the nozzle from colliding with external structures or objects, resulting in damage to the nozzle.

[0074] Under this structure, the inkjet assembly 100 can be provided with a variety of nozzles with the same length, and the mounting grooves can protect the various nozzles.

[0075] Among them, when used in conjunction with the spray assembly 220, the wiper component 240 and the suction assembly 230 in the cleaning mechanism 200, the spray assembly 220 and the suction assembly 230 can realize spray cleaning and suction drying of the nozzle in the mounting groove, and the embedded nozzle mounting structure can avoid collision and scratch with the wiper component 240 that may cause damage to the nozzle, thereby achieving cleaning of the mounting plate 110 and the nozzle while avoiding damage to the nozzle.

[0076] Furthermore, when used in conjunction with the moisturizing tank 250, the nozzle mounting structure of the embedded structure can prevent the nozzle from contacting the liquid surface in the moisturizing tank 250. Specifically, after the bottom surface of the mounting plate 110 abuts against the stopper 251 of the moisturizing tank 250, there is a gap of 1.5 mm to 3 mm between the bottom surface of the mounting plate 110 and the liquid surface of the moisturizing liquid. At this time, the gap between the end of the nozzle close to the liquid surface and the liquid surface is greater than the gap between the ground of the mounting plate 110 and the liquid surface of the moisturizing liquid, which can further prevent the nozzle from being immersed in the moisturizing liquid and causing damage to the nozzle.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
