Description

Technical Field

[0001] The present application relates to the technical field of inkjet printing equipment, and in particular to an automatic adjustment and installation mechanism for a nozzle, a printing device, and an inkjet printing system. Background Art

[0002] Inkjet printing technology has broad application prospects in multiple manufacturing fields such as information, energy, medical care, and national defense. With the rapid development of technology, it has also been increasingly used in emerging fields such as OLED, RFID, thin-film solar cells, wearable flexible devices, PCBs, smart skins and other flexible devices.

[0003] The core component of an inkjet printing device is the inkjet printing unit. Driven by a drive shaft, the inkjet printing unit achieves full-size printing on the printed substrate through repeated reciprocating motions. The inkjet printing unit is typically equipped with an ejector, which can be a single nozzle module or a nozzle module composed of multiple nozzle modules.

[0004] To improve the printing resolution, it is necessary to further configure multiple jetting parts a to work, refer to Figure 9 The multiple nozzle holes of the rear ejection member a and the multiple nozzle holes of the front ejection member a are interpolated in the arrangement direction of the multiple ejection members a to increase the density of the printing ink droplets, thereby improving the printing resolution.

[0005] In addition, in order to adapt to the need to print large-size substrates, it is necessary to splice multiple injection elements a in the length direction of the nozzle arrangement to increase the length of the substrate printed by the inkjet printing unit each time. Figure 10 . To speed up the printing efficiency of the substrate.

[0006] In the prior art, multiple jetting components are assembled before assembling the inkjet printing unit into a printing device. Typically, bolts are used to secure the jetting components to mounting brackets to form the inkjet printing unit. Manual adjustments are then made to the positions of the jetting components, and the adjusted jetting components are then secured to achieve seamless assembly.

[0007] After the inkjet printing unit is prepared, it needs to be installed in the box to protect the ejection parts and facilitate the arrangement of the supporting electronic control and ink supply equipment of the inkjet printing unit on the box. Due to the mechanical vibration of the inkjet printing unit when it is working, or the installation error of the ejection parts during installation and debugging, the splicing installation position of the multiple ejection parts will be less than ideal, so it is necessary to readjust the installation position of the multiple ejection parts of the inkjet printing unit. However, when the inkjet printing unit is placed in the box, it is difficult to move the inkjet printing unit out for adjustment. When the inkjet printing unit includes more ejection parts, the inkjet printing unit structure is more complex, the volume is larger, and it is more difficult to move out. Therefore, it is difficult to move the inkjet printing unit out for adjustment, and the splicing position of the multiple ejection parts in the inkjet printing unit is difficult to adjust, and the splicing position adjustment efficiency of the ejection parts is low.

[0041] The first adjustment structure rotates the first cam via a first rotating drive member, so that the first cam pushes the mounting plate to slide in the first direction, thereby changing the position of the injection member in the first direction.

The second adjustment structure rotates the second cam via a second rotating drive member. The second cam pushes the mating surface in the second direction, and at the same time, the first cam presses against the mounting plate in the first direction. Therefore, the second cam pushes the mounting plate to rotate in the horizontal plane around the contact point between the first cam and the mounting plate.

During the position adjustment process of the ejector, the first cam is rotated by the first rotating driving member, and the second cam is rotated by the second rotating driving member. This eliminates the need for manual fine-tuning of the position of the ejector. Therefore, when an inkjet printing unit composed of multiple ejectors is integrated into a printing device, there is no need to remove the inkjet printing unit for adjustment.

[0059] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0060] The embodiments of the present application provide an automatic nozzle adjustment and installation mechanism, a printing device, and an inkjet printing system. The automatic nozzle adjustment and installation mechanism adjusts the position of the ejector by automatically pushing the mounting plate through the rotation of a cam via a first adjustment structure and a second adjustment structure. The position of the ejector can be adjusted within the printing device without removing the inkjet printing unit, thereby ensuring adjustment accuracy and improving adjustment efficiency. This application solves the technical problems in the related art of the difficulty in removing the inkjet printing unit for adjustment, the difficulty in adjusting the splicing position of multiple ejectors in the inkjet printing unit, and the low efficiency of adjusting the splicing position of the ejectors.

[0061] Reference Figures 1-4A nozzle automatic adjustment installation mechanism includes a mounting base 1, a mounting plate 2, a first adjustment structure 3, and a second adjustment structure 4. The mounting plate 2 is for mounting an ejection element a, which is mounted on the mounting base 1. The mounting base 1 is used to be mounted on a printing device. Multiple mounting bases 1 are integrated and mounted on the printing device to form an inkjet printing unit of the printing device. The first adjustment structure 3 and the second adjustment structure 4 adjust the position of the mounting plate 2 relative to the mounting base 1 to change the position of the ejection element a on the mounting plate 2. By adjusting the position of the ejection element a, multiple ejection elements a can be seamlessly spliced.

[0062] In this embodiment, the ejection element a includes a single nozzle module, or the ejection element a includes a nozzle module formed by seamlessly splicing multiple nozzle modules. When the inkjet printing unit of the printing device is composed of multiple nozzle modules, the multiple nozzle modules in the single nozzle module are positionally adjusted using the first adjustment structure 3 and the second adjustment structure 4, and the nozzle module is also positionally adjusted using the first adjustment structure 3 and the second adjustment structure 4.

[0063] Reference Figure 1 and Figure 2 , wherein, a sinking groove 1a is provided on the top surface of the mounting seat 1, the mounting plate 2 is installed at the bottom of the sinking groove 1a, and a through groove is opened at the bottom of the sinking groove 1a for the injection member a to pass through.

[0064] Mounting plate 2 is for mounting injection element a. A through-groove 2a is defined on the top surface of mounting plate 2. After mounting plate 2 is installed, injection element a passes through groove 2a and, together with it, the through-groove of mounting seat 1. The injection surface of injection element a is positioned below mounting seat 1. The position of injection element a on mounting plate 2 can be adjusted by adjusting the position of mounting plate 2 relative to mounting seat 1.

[0065] Reference Figure 3-Figure 5 The first adjustment structure 3 includes a first rotational driver 32 and a first cam 31. The first rotational driver 32 is mounted on the mounting base 1 and is drivingly connected to the first cam 31 to drive the first cam 31 to rotate. In this embodiment, the rotation axis of the first cam 31 is vertically arranged. In this embodiment, the vertical direction is the third direction, namely the Z-axis direction in the figure. The circumferential side surface of the first cam 31 abuts against a side surface of the mounting plate 2. As the first cam 31 rotates, the first cam 31 pushes the mounting plate 2 in a first horizontal direction. In this embodiment, the first direction is the X-axis direction in the figure.

[0066] Preferably, the first cam 31 contacts the middle portion of the side surface of the mounting plate 2 to improve the stability of pushing the mounting plate 2 to slide.

[0067] The first cam 31 is rotated by the first rotary drive member 32, and the first cam 31 pushes the mounting plate 2 to slide in the first direction, thereby changing the position of the injection member a on the mounting plate 2 in the first direction. In this embodiment, the first direction is the longitudinal direction of the mounting plate 2, and the injection member a is also arranged along the first direction. The longitudinal direction of the injection member a refers to the longitudinal direction of the nozzle arrangement.

[0068] In this embodiment, the first rotation driving member 32 includes a servo motor, the rotation angle of which is controllable, thereby improving the position adjustment accuracy of the injection member a.

[0069] This arrangement uses the first rotating drive member 32 to rotate the first cam 31, which in turn pushes the mounting plate 2 to slide and adjust the longitudinal position of the ejector a. This achieves automatic longitudinal position adjustment of the ejector a. Furthermore, during rotation of the first cam 31, the pushing stroke of the mounting plate 2 is small, and the movement distance is more precise. Therefore, there is no need to manually fine-tune the position of the ejector a, nor is there a need to remove the ejector a from the printing device for adjustment. This improves the efficiency of adjusting the splicing position of the ejector a and ensures adjustment accuracy.

[0070] Reference Figure 3-Figure 5 The second adjustment structure 4 includes a second rotation driving member 42 , a second cam 41 and a matching structure 45 .

[0071] Reference Figure 3-Figure 5 The mating structure 45 is provided on the mounting plate 2. The mating structure 45 includes two mating surfaces 45a. The two mating surfaces 45a are spaced apart and arranged in a second horizontal direction. In this embodiment, the second direction is perpendicular to the first direction and is the Y-axis direction in the figure. In this embodiment, the width direction of the injection member a and the mounting plate 2 is the second direction.

[0072] Specifically, the matching structure 45 includes a matching groove, the width of which is greater than the maximum rotation diameter of the second cam 41 , and two opposite groove walls of the matching groove serve as matching surfaces 45 a.

[0073] In other embodiments, the mating structure 45 includes two mating plates, both of which are fixed on the mounting plate 2 , the two mating plates are arranged opposite to each other in the second direction, and the sides of the two mating plates facing each other are mating surfaces 45a.

[0074] The second rotational drive member 42 is mounted on the mounting base 1 and is drivingly connected to the second cam 41 to drive the second cam 41 to rotate. In this embodiment, the rotation axis of the second cam 41 is vertically arranged. The circumferential side surface of the second cam 41 abuts against the mating surface 45a, and as the second cam 41 rotates, the second cam 41 pushes the mating surface 45a in the second direction.

[0075] Reference Figure 3-Figure 5 Furthermore, the first adjustment structure 3 and the second adjustment structure 4 are spaced apart in the first direction, wherein the first cam 31 and the second cam 41 are spaced apart in the first direction. Furthermore, the first cam 31 and the second cam 41 respectively act on two opposite edges of the mounting plate 2. As the second cam 41 pushes the mating surface 45a in the second direction to push the mounting plate 2 in the second direction, because the first cam 31 abuts against one side of the mounting plate 2, and because the position where the mounting plate 2 is subjected to the force in the second direction deviates from the position of the center of gravity of the mounting plate 2, the second cam 41 pushes the mounting plate 2 to rotate about the position where the first cam 31 contacts the mounting plate 2. As the mounting plate 2 rotates, the length direction of the injection member a on the mounting plate 2 is adjusted.

[0076] The second cam 41 is driven to rotate by the second rotation driving member 42 , and the second cam 41 pushes the mounting plate 2 in the second direction to rotate the mounting plate 2 , thereby changing the length direction of the injection member a on the mounting plate 2 .

[0077] In this embodiment, the second rotation driving member 42 includes a servo motor, the rotation angle of which is controllable, thereby improving the position adjustment accuracy of the injection member a.

[0078] This arrangement utilizes the second rotary drive member 42 to rotate the second cam 41, which in turn pushes the mounting plate 2 to adjust the length of the ejector a. This allows for automatic adjustment of the length of the ejector a. Furthermore, during rotation, the second cam 41 pushes the mounting plate 2 with a smaller stroke, resulting in more precise movement. This eliminates the need for manual fine-tuning of the position of the ejector a, and eliminates the need to remove the ejector a from the printer for adjustment. This improves the efficiency of adjusting the splicing position of the ejector a and ensures precise adjustment.

[0079] Reference Figure 3-Figure 5 Furthermore, the first adjustment structure 3 also includes a first adjustment plate 33 and a first linear module 34. The first adjustment plate 33 is slidably mounted on the mounting base 1 along the first direction via a guide rail assembly. The first cam 31 and the first rotating drive member 32 are both mounted on the first adjustment plate 33. The first linear module 34 is mounted on the mounting base 1 and is drivingly connected to the first adjustment plate 33 to drive the first adjustment plate 33, the first cam 31, and the first rotating drive member 32 to move in the first direction. In this embodiment, the first linear module 34 includes a cylinder, a screw mechanism, or a linear motor.

[0080] With this arrangement, the first linear module 34 drives the first cam 31 in the first direction, thereby pressing the first cam 31 against the mounting plate 2. Subsequently, the first rotary drive member 32 drives the first cam 31 to rotate and push the mounting plate 2 in the first direction for fine-tuning. Of course, if the positional deviation of the ejection element a in the first direction is too large, the first linear module 34 can also be used to drive the first cam 31 in the first direction, thereby directly pushing against the mounting plate 2.

[0081] Furthermore, the first linear module 34 drives the first adjustment plate 33 and the components on the first adjustment plate 33 away from above the mounting plate 2. In this embodiment, the first linear module 34 moves the first adjustment plate 33 and the components on the first adjustment plate 33 away from above the sink 1a, thereby freeing up space for the mounting plate 2 to be placed in the sink 1a.

[0082] Reference Figure 3-Figure 5 The first adjustment structure 3 further includes a first elastic member 35. It should be noted that the first elastic member 35 and the first linear module 34 can be arranged simultaneously or separately. In this embodiment, the first elastic member 35 and the first linear module 34 are arranged simultaneously.

[0083] The ends of the first elastic member 35 are connected to the mounting base 1 and the first adjustment plate 33, respectively. The elastic force of the first elastic member 35 drives the first adjustment plate 33 to move in the first direction, thereby pressing the first cam 31 against the mounting plate 2. It is important to note that when the first elastic member 35 is in operation, the first linear module 34 is in a follower state, and the driving end of the first linear module 34 moves with the movement of the first adjustment plate 33. In this embodiment, the first elastic member 35 comprises a spring.

[0084] In this way, the first elastic member 35 is provided to ensure that the first cam 31 is always pressed against the mounting plate 2.

[0085] Reference Figure 3-Figure 5 A side surface of the mounting plate 2 is provided with a retaining groove 2b, into which the first cam 31 extends. The width of the retaining groove 2b is greater than the maximum rotational diameter of the first cam 31, meaning that the first cam 31 can rotate within the retaining groove 2b without interference from the walls of the retaining groove 2b. The circumferential side surface of the first cam 31 abuts the bottom of the retaining groove 2b, and as the first cam 31 rotates, it pushes against the bottom of the retaining groove 2b.

[0086] In this way, by setting the tightening groove 2b, when the second cam 41 pushes the mounting plate 2 to rotate the mounting plate 2, since the first cam 31 is restricted in the tightening groove 2b, the first cam 31 is not easy to move relative to the mounting plate 2, so the mounting plate 2 can rotate around the first cam 31 to adjust the length direction of the mounting plate 2 and the injection member a.

[0087] In this embodiment, the installation plate 2 is first rotated by the second cam 41 to adjust the length direction of the installation plate 2 and the spray element a, and then the installation plate 2 is slid by the first cam 31 to adjust the position of the installation plate 2 and the spray element a in the length direction.

[0088] With reference to Figure 3-Figure 6 The spray head automatic adjustment mounting mechanism further comprises a guide structure 6 which is arranged in the second direction offset from the second adjusting structure 4, and the guide structure 6 comprises a guide groove 62 and a guide rod 61.

[0089] The guide groove 62 is arranged on the installation plate 2, and the length direction of the guide groove 62 is arranged along the first direction. It can be understood that, in an ideal state, the length direction of the installation plate 2 and the length direction of the spray element a are both arranged along the first direction, and the length direction of the guide groove 62 is consistent with the length direction of the installation plate 2. The guide rod 61 is vertically fixed on the mounting base 1 and fixed on the groove bottom of the sink 1a, and the guide rod 61 is arranged in the guide groove 62 and slidably arranged in the guide groove 62. The width of the guide groove 62 is greater than the diameter of the guide rod 61.

[0090] When the installation plate 2 is rotated by the second cam 41, the guide rod 61 slides in the guide groove 62 relative to the guide groove 62. With the rotation of the installation plate 2, the guide rod 61 abuts against the groove wall of the guide groove 62. When the length direction of the installation plate 2 and the length direction of the spray element a are adjusted, the length direction of the installation plate 2 and the length direction of the spray element a are both arranged along the first direction. At this time, the guide rod 61 abuts against the groove wall of the guide groove 62 in the second direction, and the second cam 41 also abuts against the installation plate 2 in the second direction through the abutting surface 45a, so that the installation plate 2 is clamped and limited in the second direction by the guide rod 61 and the second cam 41.

[0091] In this way, after the length direction of the installation plate 2 and the length direction of the spray element a are adjusted, the position of the installation plate 2 and the spray element a in the length direction is adjusted by pushing the installation plate 2 by the first cam 31. Because the first cam 31 and the guide rod 61 limit the installation plate 2, the installation plate 2 is not easy to be deflected when being pushed by the first cam 31, which ensures that the installation plate 2 and the spray element a move along the first direction and ensures the position adjustment accuracy of the spray element a. After the length direction of the installation plate 2 is adjusted, the first linear module 34 works to make the first cam 31 abut against the installation plate 2, and then the position of the installation plate 2 in the first direction is adjusted by rotating the first cam 31.

[0092] It should be noted that when the second cam 41 pushes the mounting plate 2 to rotate, the guide rod 61 slides relative to the guide slot 62 in both the first and second directions. Therefore, the width of the guide slot 62 must be greater than the diameter of the guide rod 61 to avoid interference with the movement of the guide rod 61. Because the rotation angle of the mounting plate 2 is relatively small, the width of the guide slot 62 only needs to be slightly greater than the diameter of the guide rod 61. Specifically, the width of the guide slot 62 is 1-5 mm greater than the diameter of the guide rod 61.

[0093] In addition, when the second cam 41 pushes the mounting plate 2 to rotate, the first linear module 34 is in a follow-up state, and the elastic force of the first elastic member 35 causes the first cam 31 to continuously press against the mounting plate 2. When the mounting plate 2 rotates, the contact position between the mounting plate 2 and the first cam 31 will move in both the first direction and the second direction due to the mounting plate 2 itself. Because the first elastic member 35 elastically presses the first cam 31 against the mounting plate 2, it supports the movement of the mounting plate 2 in the first direction. It should be noted that due to the arrangement of the guide rod 61 and the guide slot 62, if the first cam 31 hard contacts the mounting plate 2, when the mounting plate 2 rotates, the guide rod 61 and the guide slot 62 will have difficulty in relative movement, resulting in the inability of the mounting plate 2 to rotate and adjust.

[0094] Under the restriction of the first cam 31 , the second cam 41 and the guide rod 61 on the mounting plate 2 , the movement damping of the mounting plate 2 is greater, and the adjustment accuracy of the mounting plate 2 is higher.

[0095] Reference Figure 3-Figure 5 The second adjustment structure 4 further includes a second adjustment plate 43 and a second linear module 44. The second adjustment plate 43 is slidably mounted on the mounting base 1 along the first direction via a guide rail assembly. The second cam 41 and the second rotation drive member 42 are both mounted on the second adjustment plate 43. The second linear module 44 is mounted on the mounting base 1 and is drivingly connected to the second adjustment plate 43 to drive the second adjustment plate 43, the second cam 41, and the second rotation drive member 42 to move in the first direction. In this embodiment, the second linear module 44 includes a cylinder, a linear motor, or a screw mechanism.

[0096] When adjusting the length of the mounting plate 2 and the injection member a, the second linear module 44 drives the second cam 41 to extend between the two mating surfaces 45a. The rotation of the second cam 41 pushes the mounting plate 2 to rotate. When assembling the mounting plate 2 onto the mounting base 1, the second linear module 44 drives the second adjustment plate 43 and its components away from the mounting plate 2 to facilitate placement of the mounting plate 2 into the sink 1a.

[0097] Reference Figure 3-Figure 6Further, at least one of the first adjusting structure 3 and the second adjusting structure 4 further comprises a locking assembly 5. The sliding of the first adjusting plate 33 or the second adjusting plate 43 is limited by the locking assembly 5. When the mounting plate 2 and the mounting base 1 are assembled, the first adjusting plate 33 and the second adjusting plate 43 are limited to one side of the sink 1a by limiting the sliding of the first adjusting plate 33 and the second adjusting plate 43, and the position above the sink 1a is released, so as to facilitate the assembly of the mounting plate 2 provided with the spray member a to the mounting base 1.

[0098] With reference to Figure 3-Figure 6 In the embodiment, the first adjusting structure 3 and the second adjusting structure 4 both comprise the locking assembly 5. The locking assembly 5 comprises a locking fitting assembly 51. The locking fitting assembly 51 comprises an inserting rod 511 and an elastic fitting block 512. The inserting rod 511 is fixedly connected to the first adjusting plate 33 or the second adjusting plate 43. The elastic fitting block 512 is fixed to the mounting base 1. The elastic fitting block 512 is provided with an inserting slot 512a on the side surface. The head portion of the inserting rod 511 has a size larger than the rod portion of the inserting rod 511. The shape of the inserting slot 512a is matched with the head portion of the inserting rod 511. When the inserting rod 511 slides in the first direction, the head portion of the inserting rod 511 is inserted into the inserting slot 512a.

[0099] It can be understood that the slot of the inserting slot 512a is provided in a closing manner. When the head portion of the inserting rod 511 is inserted into the inserting slot 512a, the elastic deformation of the elastic fitting block 512 supports the slot of the inserting slot 512a to be opened. When the head portion of the inserting rod 511 is inserted into the inserting slot 512a, the slot of the inserting slot 512a limits the head portion of the inserting rod 511 to move away, so as to limit the sliding of the first adjusting plate 33 and the second adjusting plate 43.

[0100] In the embodiment, the material of the elastic fitting block 512 comprises plastic.

[0101] Further, the locking assembly 5 further comprises a locking bolt 52. The locking bolt 52 is threadedly inserted into the inserting rod 511. The locking bolt 52 is adapted to abut against the mounting base 1.

[0102] In this way, when the inserting rod 511 and the inserting slot 512a are in the inserting fitting, the locking bolt 52 is abutted against the mounting base 1 by tightening the locking bolt 52, so as to further limit the movement of the inserting rod 511, and stably limit the movement of the first adjusting plate 33 or the second adjusting plate 43.

[0103] With reference to Figure 1-Figure 3The automatic printhead adjustment and installation mechanism also includes multiple sets of clamping structures 7, which are respectively applied to multiple corners of the mounting plate 2 to secure the mounting plate 2 to the mounting base 1. The multiple clamping structures 7 compress the mounting plate 2, thereby fixing its position relative to the mounting base 1. After the automatic position adjustment of the ejector a is completed, the position of the ejector a is automatically fixed by fixing the mounting plate 2, achieving automatic adjustment and fixation of the position of the ejector a. This facilitates the adjustment and fixation of the position of the ejector a within the printing device.

[0104] The clamping structure 7 is mounted on the mounting base 1, the first adjustment structure 3, or the second adjustment structure 4. In this embodiment, the clamping structure 7 is mounted on the first adjustment structure 3 and the second adjustment structure 4. Specifically, the clamping structure 7 is mounted on both the first adjustment plate 33 and the second adjustment plate 43. The clamping structure 7 moves with the first adjustment plate 33 or the second adjustment plate 43. After the clamping structure 7 moves above the mounting plate 2, it clamps and secures the mounting plate 2.

[0105] With this arrangement, the pressing structure 7 moves with the first adjustment plate 33 and the second adjustment plate 43 , thereby avoiding interference with the assembly of the mounting plate 2 .

[0106] In other embodiments, the pressing structure 7 is mounted on the mounting base 1 , or is mounted on the mounting base 1 through a linear module.

[0107] The pressing structure 7 includes a pressing linear module, and the driving end of the pressing linear module is suitable for pressing down and pressing against the mounting plate 2. In this embodiment, the pressing linear module includes a cylinder.

[0108] Reference Figure 7 and Figure 8 Optionally, the automatic nozzle adjustment installation mechanism further includes multiple sets of height adjustment structures 8, which support the multiple corners of the mounting plate 2. The height adjustment structures 8 include a backing plate 81, multiple first adjustment bolts 82, and multiple second adjustment bolts 83. The backing plate 81 is connected to the bottom of the sink 1a of the mounting base 1 via the first adjustment bolts 82 and the second adjustment bolts 83, and the backing plate 81 supports the mounting plate 2.

[0109] Reference Figure 7 and Figure 8 The first adjusting bolt 82 passes through the backing plate 81 and is threadedly connected to the mounting base 1, with the head of the first adjusting bolt 82 tightly against the backing plate 81. The second adjusting bolt 83 is threadedly passed through the backing plate 81 and tightly against the mounting base 1. A first adjusting bolt 82 and a second adjusting bolt 83 are each provided at the corners of the backing plate 81.

[0110] In this way, by screwing the first adjusting bolt 82 and the second adjusting bolt 83 on the pad 81, the corners of the pad 81 are adjusted in a push-pull manner to ensure that the pad 81 is in a horizontal state, and by adjusting multiple pads 81, the heights of multiple pads 81 are consistent. When multiple pads 81 support the mounting plate 2, the horizontality of the mounting plate 2 can be guaranteed to ensure the horizontality of the injection surface of the injection part a.

[0111] It should be noted that when the mounting plate 2 is assembled to the mounting seat 1 , the horizontal adjustment of the injection surface of the injection member a on the mounting plate 2 is completed.

[0112] An embodiment of the present application provides an automatic adjustment and installation mechanism for a nozzle, in which the injection component a is installed on a mounting plate 2. The position of the injection component a is adjusted by adjusting the position of the mounting plate 2. By adjusting the position of the injection component a accordingly, seamless splicing of multiple injection components a can be achieved to meet the requirements of high-resolution and high-efficiency inkjet printing processing.

[0113] The first adjustment structure 3 rotates the first cam 31 via the first rotating drive member 32, so that the first cam 31 pushes the mounting plate 2 to slide in the first direction, thereby changing the position of the injection member a in the first direction. The first cam 31 pushes the injection member a in a manner that has high stroke accuracy and facilitates precise adjustment of the position of the injection member a in the first direction. The second adjustment structure 4 rotates the second cam 41 via the second rotating drive member 42, and the second cam 41 pushes the mating surface 45a in the second direction. At the same time, the first cam 31 presses against the mounting plate 2 in the first direction. Therefore, the second cam 41 pushes the mounting plate 2 to rotate in the horizontal plane around the contact point between the first cam 31 and the mounting plate 2. By adjusting the length direction of the injection member a, the position of the injection member a in the horizontal plane can be adjusted in multiple directions to support the precise splicing of multiple injection members a.

[0114] The position of the ejector a is adjusted by first rotating the mounting plate 2 to adjust the length of the ejector a, and then pushing the mounting plate 2 to move in the first direction to adjust the position of the ejector a in the first direction. During the position adjustment of the ejector a, the first rotating drive member 32 rotates the first cam 31, and the second rotating drive member 42 rotates the second cam 41. This eliminates the need for manual fine-tuning of the position of the ejector a. Therefore, when an inkjet printing unit composed of multiple ejectors a is integrated into a printing device, there is no need to remove the inkjet printing unit for adjustment. The position of each ejector a can be adjusted directly within the printing device via the first adjustment structure 3 and the second adjustment structure 4, ensuring not only adjustment accuracy but also improved ejector a position adjustment efficiency.
