[0036] Currently, inkjet printing equipment is usually composed of multiple printhead assemblies 110 spliced together to meet practical needs. However, deviations may occur during the splicing process, resulting in ink prints from the spliced inkjet printer not meeting requirements, thus causing waste. In addition, manual adjustment of the printhead assembly 110 requires disassembly and reinstallation, which seriously affects production efficiency and can also easily cause operator fatigue.
[0037] Based on this, this application proposes an inkjet printing device that can automatically fine-tune the printhead assembly 110 through a first adjustment component and a second adjustment component, thereby saving labor costs and improving production efficiency.
[0038] The following reference Figure 1 , Figure 2 , Figure 4 and Figure 7 This application describes an inkjet printing apparatus according to embodiments of the present application.
[0039] It is understood that the inkjet printing apparatus of this application embodiment includes: a base plate 100, a printhead assembly 110, and a first adjustment assembly. The base plate 100 is provided with a mounting port; the printhead assembly 110 is disposed in the mounting port, and a first mounting plate 101 is provided on one side of the printhead assembly 110. The first mounting plate 101 is connected to the base plate 100 through an elastic assembly. A first connecting plate 120 is provided on the first mounting plate 101, and a first protrusion 121 is provided on one side of the first connecting plate 120; the first adjustment assembly... The device includes a first driving member 140 and a first push block 141. The cross-sectional area of the first push block 141 gradually decreases from top to bottom. The first push block 141 is connected to the first driving member 140. The side wall of the first push block 141 abuts against the side wall of the first protrusion 121. The first driving member 140 is used to drive the first push block 141 to move in the vertical direction. The first push block 141 is used to make the first protrusion 121 drive the nozzle assembly 110, so that the nozzle assembly 110 moves closer to or away from the side where the first protrusion 121 is provided.
[0040] The beneficial effects of the inkjet printing device in this application embodiment can be manifested as follows: by placing the printhead assembly 110 inside the mounting port, the printhead assembly 110 can only be fine-tuned, avoiding excessive adjustment range due to improper operation; by setting the first push block 141 as a structure with a cross-sectional area that gradually decreases from top to bottom, when the first drive member 140 drives the first push block 141, the first push block 141 causes the first protrusion 121 to move, thereby driving the printhead assembly 110 to move toward the side where the first protrusion 121 is provided, or to move away from the side where the first protrusion 121 is provided, thereby realizing the fine-tuning operation of the printhead assembly 110 in this direction.
[0041] For example, in some embodiments, reference is made to Figure 1 , Figure 2 , Figure 4 and Figure 7 In this embodiment, the elastic component is a third spring, the first driving member 140 is a first control motor, the first driving member 140 is controlled by a control terminal, the side wall of the first push block 141 abuts against the side wall of the first protrusion 121, when the first driving member 140 receives the signal transmitted by the control terminal, the first driving member 140 drives the first push block 141 to move in the vertical direction, thereby causing the first protrusion 121 to drive the nozzle assembly 110, so that the nozzle assembly 110 moves toward the side of the first connecting plate 120 where the first protrusion 121 is provided, or moves away from the side where the first protrusion 121 is provided. For example, when the first driving member 140 drives the first push block 141 to move downward in the vertical direction, the side wall of the first push block 141 abuts against the side wall of the first protrusion 121, and the cross-sectional area of the first push block 141 gradually decreases from top to bottom. This causes the first push block 141 to press against the first protrusion 121. The first protrusion 121 is located on the first connecting plate 120, which is fixedly connected to the first mounting plate 101. The first mounting plate 101 is located on the nozzle assembly 110. Therefore, pressing against the first protrusion 121 will also drive the nozzle. Component 110 moves along a first direction, that is, towards the side of the first connecting plate 120 where the first protrusion 121 is located. When the first driving member 140 drives the first push block 141 to move vertically upward, the first push block 141 no longer presses against the first protrusion 121. However, under the action of the elastic component, the first protrusion 121 moves towards the first push block 141, thereby driving the nozzle assembly 110 away from the side where the first protrusion 121 is located. This allows for fine-tuning of the nozzle assembly 110 in this direction, improving efficiency and reducing the required labor costs. Placing the nozzle assembly 110 inside the mounting port facilitates determining the approximate correct orientation of the nozzle assembly 110 beforehand, so that any deviation of the nozzle assembly 110 can be adjusted only through fine-tuning.
[0042] It is understood that the inkjet printing device also includes a second adjustment assembly, which includes a second drive member 150 and a second pusher 151. The printhead assembly 110 is also provided with a second mounting plate 102, which is located on the side opposite to the first mounting plate 101. A second connecting plate 130 is provided on the second mounting plate 102. The side wall of the second pusher 151 abuts against the side wall of the second connecting plate 130. The cross-sectional area of the second pusher 151 gradually decreases from top to bottom. The second drive member 150 is used to drive the second pusher 151 to move in the vertical direction. The second pusher 151 is used to press the second connecting plate 130 to move the printhead assembly 110 closer to or away from the side where the first pusher 141 is provided.
[0043] For example, in some embodiments, reference is made to Figure 2 , Figure 3 , Figure 6 and Figure 7 In this embodiment, the second driving member 150 is a second control motor, and the side wall of the second push block 151 abuts against the side wall of the second connecting plate 130. When the second driving member 150 receives the signal transmitted by the control terminal, the second driving member 150 drives the second push block 151 to move in the vertical direction, thereby causing the second connecting plate 130 to drive the nozzle assembly 110, so that the nozzle assembly 110 moves towards the first push block 141 or away from the first push block 141. For example, when the second driving member 150 drives the second push block 151 to move downward in the vertical direction, the side wall of the second push block 151 abuts against the side wall of the second connecting plate 130, and the cross-sectional area of the second push block 151 gradually decreases from top to bottom. This causes the second push block 151 to press against the second connecting plate 130. The second connecting plate 130 is fixedly connected to the second mounting plate 102, which is also located on the nozzle assembly 110. Therefore, pressing against the second connecting plate 130 will also cause the nozzle assembly 110 to move towards the nozzle. The second pusher 151 moves towards the direction of the first pusher 141. When the second drive member 150 drives the second pusher 151 to move upward in the vertical direction, the second pusher 151 no longer presses the second connecting plate 130. However, under the action of the elastic component, the second connecting plate 130 moves towards the direction of the second pusher 151, thereby driving the nozzle assembly 110 to move away from the first pusher 141. This enables the nozzle assembly 110 to be fine-tuned in this direction, further improving the accuracy of the nozzle assembly 110 splicing position and increasing efficiency.
[0044] It is understood that the inkjet printing device also includes a first fixed frame 160 and a second fixed frame 170. The first push block 141 is connected to the first drive member 140 through a first connecting rod, and the second push block 151 is connected to the second drive member 150 through a second connecting rod. The first connecting rod is movably inserted through the first fixed frame 160, and the second connecting rod is movably inserted through the second fixed frame 170. The first fixed frame 160 is connected to the base plate 100 through a first fastener, and the second fixed frame 170 is connected to the base plate 100 through a second fastener. The first fixed frame 160 is used to limit the first connecting rod, and the second fixed frame 170 is used to limit the second connecting rod.
[0045] For example, in some embodiments, reference is made to Figure 1 and Figure 5 In this embodiment, the first fixing frame 160 and the second fixing frame 170 are disposed on opposite sides of the nozzle assembly 110. The first fixing frame 160 is fixedly connected to the base plate 100 by a first fastener, and the second fixing frame 170 is connected to the base plate 100 by a second fastener. The first fixing frame 160 is provided with a first through hole, through which a first connecting rod can be movably inserted, so as to limit the first push block 141 connected to the first connecting rod, causing the first push block 141 to only move in the vertical direction. Similarly, the second fixing frame 170 is provided with a second through hole, through which a second connecting rod can be movably inserted, so as to limit the second push block 151 connected to the second connecting rod, causing the second push block 151 to only move in the vertical direction.
[0046] It is understood that the second connecting plate 130 is provided with a second protrusion 131 and a third protrusion 132. The side wall of the second protrusion 131 away from the second connecting plate 130 is inclined in a direction away from the third protrusion 132. The side wall of the third protrusion 132 away from the second connecting plate 130 is inclined in a direction away from the second protrusion 131. The side wall of the second push block 151 abuts against the side wall of the third protrusion 132 near the second protrusion 131. The side wall of the second push block 151 abuts against the side wall of the second protrusion 131 near the third protrusion 132.
[0047] For example, in some embodiments, reference is made to Figure 2 , Figure 4 and Figure 7In this embodiment, the second connecting plate 130 is provided with a second protrusion 131 and a third protrusion 132. The side wall of the second protrusion 131 away from the second connecting plate 130 is inclined in a direction away from the third protrusion 132. The side wall of the third protrusion 132 away from the second connecting plate 130 is inclined in a direction away from the second protrusion 131. A "V"-shaped groove is formed between the second protrusion 131 and the third protrusion 132. The second push block 151 is engaged in the "V"-shaped groove and abuts against the side wall of the second protrusion 131 and the side wall of the third protrusion 132. The design of the second protrusion 131 and the third protrusion 132 makes it convenient for the second push block 151 to move the nozzle assembly 110 in a direction closer to or away from the first push block 141 when the second protrusion 131 and the third protrusion 132 move.
[0048] It is understood that: the first fixing frame 160 is provided with a first spring 162, the first spring 162 is connected to the side wall of the first mounting plate 101, and the first push block 141 causes the first protrusion 121 to drive the nozzle assembly 110 to move in the same direction as the length of the first spring 162.
[0049] For example, in some embodiments, reference is made to Figure 1 and Figure 7 In this embodiment, the first mounting plate 101 and the first fixing frame 160 are connected by the first spring 162. By setting the first spring 162, when the first driving member 140 drives the first push block 141 to move upward in the vertical direction, the first spring 162 cooperates with the elastic component to make the first protrusion 121 move in the direction of the first push block 141, thus avoiding the situation where the elastic component has insufficient force on the nozzle assembly 110.
[0050] It is understandable that the first fixing frame 160 is also provided with a second spring 161. The second spring 161 is connected to the side wall of the first mounting plate 101. The second push block 151 causes the second protrusion 131 and the third protrusion 132 to move the nozzle assembly 110 in the same direction as the length of the second spring 161. The length of the second spring 161 is perpendicular to the length of the first spring 162.
[0051] For example, in some embodiments, reference is made to Figure 1 and Figure 7 In this embodiment, the first mounting plate 101 and the first fixing frame 160 are connected by the second spring 161. By setting the second spring 161, when the first driving member 140 drives the second push block 151 to move upward in the vertical direction, the second spring 161 cooperates with the elastic component to make the second protrusion 131 and the third protrusion 132 move in the direction of the second push block 151, thus avoiding the situation where the elastic component has insufficient force on the nozzle assembly 110.
[0052] It is understood that the nozzle assembly 110 also includes a nozzle 111 and a housing, with the nozzle 111 located on one side of the housing and inside the mounting port.
[0053] For example, in some embodiments, reference is made to Figure 3 In this embodiment, the nozzle 111 is located inside the mounting port, which helps to limit the approximate installation position of the nozzle 111. Therefore, only minor adjustments to the nozzle 111 are needed, without the need for significant adjustments. At the same time, most of the nozzle 111 is hidden inside the base plate 100 and the housing, which helps to protect the nozzle 111, avoid unnecessary damage, extend the service life of the nozzle 111, and reduce costs.
[0054] It is understood that the printhead assembly 110 also includes a first ink tube 103 and a second ink tube 104. The first mounting plate 101 is also provided with the first ink tube 103, and the second mounting plate 102 is also provided with the second ink tube 104. The first ink tube 103 is located between the printhead assembly 110 and the first connecting plate 120, and the second ink tube 104 is located between the printhead assembly 110 and the second connecting plate 130.
[0055] For example, in some embodiments, reference is made to Figure 1 and Figure 2 In this embodiment, the first ink tube 103 and the second ink tube 104 are located on opposite sides of the printhead assembly 110. The first ink tube 103 is located between the printhead assembly 110 and the first connecting plate 120, and the second ink tube 104 is located between the printhead assembly 110 and the second connecting plate 130, so as to facilitate timely addition of ink to the printhead assembly 110.
[0056] It is understandable that both the first push block 141 and the second push block 151 are tapered screws.
[0057] For example, in some embodiments, reference is made to Figure 2 In this embodiment, both the first push block 141 and the second push block 151 are tapered screws, which can achieve the desired effect while reducing the required cost. Furthermore, the uniform sidewalls of the tapered screws make fine-tuning more precise.
[0058] The inkjet apparatus according to the second aspect of the application includes the inkjet printing apparatus of the first aspect of the application described above.
[0059] According to the inkjet printing device of this application, by placing the printhead assembly 110 inside the mounting port, the printhead assembly 110 can only be fine-tuned, avoiding excessive adjustment due to improper operation. By setting the first push block 141 to a structure with a cross-sectional area gradually decreasing from top to bottom, when the first drive member 140 drives the first push block 141, the first push block 141 causes the first protrusion 121 to move, thereby driving the printhead assembly 110 to move towards the side where the first protrusion 121 is located, or towards the side away from the first protrusion 121, thus realizing fine-tuning operation of the printhead assembly 110 in this direction. By providing a second adjustment component, the printhead assembly 110 can be fine-tuned in a direction closer to the first push block 141 or away from the first push block 141. By using the inkjet printing device of this application, the inkjet equipment can fine-tune the printhead assembly 110 without the need for manual disassembly and reinstallation of improperly spliced printhead assemblies 110, making the operation of the inkjet equipment more efficient.
[0060] Since the inkjet device includes the inkjet printing apparatus of the first aspect embodiment, the corresponding contents of the inkjet printing apparatus of the first aspect embodiment can be applied to the inkjet device of the second aspect, and have the same implementation principle and technical effect. To avoid redundancy, it will not be described in detail here.
[0061] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
