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, PCB, smart skins and other flexible devices.

[0003] The core component of the inkjet printing equipment is the inkjet printing unit. Under the drive of the drive shaft, the inkjet printing unit realizes full-size printing of the printed substrate through multiple reciprocating motions of the drive shaft. The inkjet printing unit is generally 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 Fig. 9 The plurality of nozzle holes of the rear ejection member a and the plurality of nozzle holes of the front ejection member a are interpolated in the arrangement direction of the plurality of 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, multiple injection elements a need to be spliced ​​in the length direction of the nozzle arrangement to increase the length of the substrate printed by the inkjet printing unit each time. Fig.10 . To speed up the printing efficiency of the substrate.

[0006] In the related art, before assembling the inkjet printing unit to the printing device, a plurality of jet components are spliced ​​together. Generally, the jet components are fixed to the mounting base by bolts to assemble the inkjet printing unit, and the positions of the jet components are fine-tuned manually, and the jet components with adjusted positions are fixed to achieve seamless splicing of the plurality of jet components.

[0007] After the inkjet printing unit is prepared, it needs to be installed in the box to protect the injection parts and to 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 when the injection parts are installed and debugged, the splicing installation position of multiple injection parts will be less than ideal, so it is necessary to readjust the installation position of multiple injection parts of the inkjet printing unit. However, the inkjet printing unit is placed in the box, and it is difficult to move the inkjet printing unit out for adjustment.

DETAILED DESCRIPTION

[0059] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0060] The embodiment of the present application provides a nozzle automatic adjustment installation mechanism, a printing device and an inkjet printing system. The nozzle automatic adjustment installation mechanism automatically pushes the installation plate by rotating the cam through the first adjustment structure and the second adjustment structure to adjust the position of the injection member. The position of the injection member can be adjusted in the printing device without removing the inkjet printing unit, thereby ensuring the adjustment accuracy and improving the adjustment efficiency. The present application solves the technical problems in the related art that it is difficult to remove the inkjet printing unit for adjustment, the splicing position of multiple injection members in the inkjet printing unit is difficult to adjust, and the splicing position adjustment efficiency of the injection members is low.

[0061] Reference Figure 1-Figure 4A nozzle automatic adjustment installation mechanism includes a mounting seat 1, a mounting plate 2, a first adjustment structure 3 and a second adjustment structure 4. The mounting plate 2 is used to install the injection member a, and the mounting plate 2 is installed on the mounting seat 1. The mounting seat 1 is used to be installed on a printing device. Multiple mounting seats 1 are integrated and installed 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 seat 1 to change the position of the injection member a on the mounting plate 2. By adjusting the position of the injection member a, multiple injection members a can be seamlessly spliced.

[0062] In this embodiment, the ejection member a includes a single nozzle module, or the ejection member 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 by the first adjustment structure 3 and the second adjustment structure 4, and the nozzle module is also positionally adjusted by the first adjustment structure 3 and the second adjustment structure 4.

[0063] Reference Figure 1 and Figure 2 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 for the injection member a to pass through is opened at the bottom of the sinking groove 1a.

[0064] The mounting plate 2 is used for mounting the injection member a. A through mounting groove 2a is provided on the top surface of the mounting plate 2. After the injection member a is mounted on the mounting plate 2, the injection member a passes through the mounting groove 2a and the through groove of the mounting seat 1. The injection surface of the injection member a is located below the mounting seat 1. The position of the injection member a on the mounting plate 2 can be adjusted by adjusting the position of the mounting plate 2 relative to the mounting seat 1.

[0065] Reference Figure 3-Figure 5 The first adjustment structure 3 includes a first rotating driving member 32 and a first cam 31. The first rotating driving member 32 is installed on the mounting seat 1. The first rotating driving member 32 is 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, that is, the Z-axis direction in the figure. The circumferential side surface of the first cam 31 abuts against one side surface of the mounting plate 2, and as the first cam 31 rotates, the first cam 31 pushes the mounting plate 2 to move in the 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 driven to rotate by the first rotating driving member 32, and the first cam 31 is used to push the mounting plate 2 to slide in the first direction, so that the position of the injection member a on the mounting plate 2 in the first direction can be changed. In this embodiment, the first direction is the length direction of the mounting plate 2, and the length direction of the injection member a is also arranged along the first direction. The length direction of the injection member a refers to the length direction of the arrangement of the spray holes.

[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] In this arrangement, the first cam 31 is driven to rotate by the first rotating driving member 32, and the first cam 31 is used to push the mounting plate 2 to slide and adjust the position of the injection member a in its length direction, so that the position of the injection member a in its length direction is automatically adjusted, and during the rotation of the first cam 31, the pushing stroke of the mounting plate 2 is small, and the moving distance is more precise. Therefore, there is no need to manually fine-tune the position of the injection member a, and there is no need to take out the injection member a integrated into the printing device for adjustment, which improves the splicing position adjustment efficiency of the injection member a and ensures the 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 matching structure 45 is provided on the mounting plate 2, and the matching structure 45 includes two matching surfaces 45a, and the two matching surfaces 45a are arranged opposite to each other in a second horizontal direction. In this embodiment, the second direction is perpendicular to the first direction, and the second direction 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 are 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 rotating driving member 42 is mounted on the mounting base 1, and the second rotating driving member 42 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 matching surface 45a, and as the second cam 41 rotates, the second cam 41 pushes the matching surface 45a toward the second direction.

[0075] Reference Figure 3-Figure 5 , further, the first adjustment structure 3 and the second adjustment structure 4 are arranged at intervals in the first direction, wherein the first cam 31 and the second cam 41 are arranged at intervals in the first direction, and further, the first cam 31 and the second cam 41 act on two opposite edges of the mounting plate 2 respectively. As the second cam 41 pushes the mating surface 45a in the second direction to push the mounting plate 2 in the second direction, since the first cam 31 is pressed against one side of the mounting plate 2, and since the position where the mounting plate 2 is subjected to the force in the second direction is offset from the position of the center of gravity of the mounting plate 2, the second cam 41 pushes the mounting plate 2 to rotate around the position where the first cam 31 contacts the mounting plate 2, and 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 rotating driving member 42 , and the second cam 41 is used to push 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] In this arrangement, the second cam 41 is driven to rotate by the second rotating driving member 42, and the second cam 41 is used to push the mounting plate 2 to adjust the length direction of the injection member a, thereby realizing automatic adjustment of the length direction of the injection member a. In addition, during the rotation of the second cam 41, the pushing stroke of the mounting plate 2 is small, and the moving distance is more precise. Therefore, there is no need to manually fine-tune the position of the injection member a, and there is no need to remove the injection member a integrated into the printing device for adjustment, thereby improving the splicing position adjustment efficiency of the injection member a and ensuring the adjustment accuracy.

[0079] Reference Figure 3-Figure 5 , further, 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 arranged on the mounting seat 1 along the first direction through a guide rail group, and the first cam 31 and the first rotating driving member 32 are both installed on the first adjustment plate 33. The first linear module 34 is installed on the mounting seat 1, and the first linear module 34 is drivingly connected to the first adjustment plate 33 to drive the first adjustment plate 33, the first cam 31 and the first rotating driving 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] In this way, the first cam 31 can be driven to move in the first direction by the first linear module 34, so as to be pressed against the mounting plate 2, and then the first cam 31 can be driven to rotate and push the mounting plate 2 to fine-tune the position in the first direction by the first rotating driving member 32. Of course, when the position deviation of the injection member a in the first direction is too large, the first linear module 34 can also be used to drive the first cam 31 to move in the first direction, and directly push the mounting plate 2.

[0081] In addition, the first linear module 34 drives the first adjustment plate 33 and the components on the first adjustment plate 33 to move 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 making room for placing the mounting plate 2 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 two ends of the first elastic member 35 are connected to the mounting seat 1 and the first adjustment plate 33 respectively, and the elastic force of the first elastic member 35 drives the first adjustment plate 33 to move in the first direction, and drives the first cam 31 to press against the mounting plate 2. It should be noted that when the first elastic member 35 is working, the first linear module 34 is in a follow-up 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 includes a spring.

[0084] In this way, by providing the first elastic member 35 , it is ensured that the first cam 31 is always pressed against the mounting plate 2 .

[0085] Reference Figure 3-Figure 5 , wherein a side surface of the mounting plate 2 is provided with a tightening groove 2b, and the first cam 31 extends into the tightening groove 2b. The width of the tightening groove 2b is greater than the maximum rotation diameter of the first cam 31, that is, the first cam 31 will not be interfered by the groove wall of the tightening groove 2b when rotating in the tightening groove 2b. The circumferential side surface of the first cam 31 abuts against the groove bottom of the tightening groove 2b, and as the first cam 31 rotates, the first cam 31 pushes the groove bottom of the tightening groove 2b.

[0086] In this way, by setting the clamping groove 2b, when the second cam 41 pushes the mounting plate 2 to make the mounting plate 2 rotate, since the first cam 31 is restricted in the clamping groove 2b, it is not easy for the first cam 31 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 second cam 41 is first used to push the mounting plate 2 to rotate to adjust the length direction of the mounting plate 2 and the injection member a, and then the first cam 31 is used to push the mounting plate 2 to slide to adjust the position of the mounting plate 2 and the injection member a in their length direction.

[0088] Reference Figure 3-Figure 6 The nozzle automatic adjustment installation mechanism further includes a guide structure 6 , which is staggered with the second adjustment structure 4 in the second direction, and the guide structure 6 includes a guide groove 62 and a guide rod 61 .

[0089] The guide groove 62 is provided in the mounting 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 directions of the injection member a and the mounting plate 2 are arranged along the first direction, and the length direction of the guide groove 62 here is consistent with the length direction of the mounting plate 2. The guide rod 61 is vertically fixed on the mounting seat 1 and fixed to the bottom of the sink 1a. The guide rod 61 is inserted into 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] As the second cam 41 pushes the mounting plate 2 to rotate, the guide rod 61 slides in the guide groove 62 relative to the guide groove 62. As the mounting plate 2 rotates, the guide rod 61 abuts against the groove wall of the guide groove 62. When the length direction adjustment of the mounting plate 2 and the injection member a is completed, the length directions of the mounting plate 2 and the injection member 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 mounting plate 2 in the second direction through the abutting mating surface 45a, so the mounting plate 2 is clamped and limited by the guide rod 61 and the second cam 41 in the second direction.

[0091] With this arrangement, after the adjustment of the length direction of the mounting plate 2 and the injection member a is completed, when the first cam 31 is used to push the mounting plate 2 to adjust the position of the mounting plate 2 and the injection member a in the length direction, the mounting plate 2 is not easily deflected when pushed by the first cam 31 due to the limitation of the mounting plate 2 by the first cam 31 and the guide rod 61, so that the mounting plate 2 is ensured to move along the first direction and the position adjustment accuracy of the injection member a is ensured. After the adjustment of the length direction of the mounting plate 2 is completed, the first linear module 34 works to make the first cam 31 hard against the mounting plate 2, and then the position of the mounting plate 2 in the first direction is adjusted by driving the first cam 31 to rotate.

[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 direction and the second direction, so the width of the guide slot 62 needs to be greater than the diameter of the guide rod 61 to avoid interference with the movement of the guide rod 61. Since the rotation angle of the mounting plate 2 is 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 greater than the diameter of the guide rod 61 by 1-5 mm.

[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 keeps the first cam 31 pressed 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. Since the first elastic member 35 elastically presses the first cam 31 against the mounting plate 2, the mounting plate 2 is supported to move in the first direction. It should be noted that due to the setting of the guide rod 61 and the guide groove 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 groove 62 are difficult to move relative to each other, 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 , wherein 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 arranged on the mounting seat 1 along the first direction through a guide rail group, and the second cam 41 and the second rotating driving member 42 are both installed on the second adjustment plate 43. The second linear module 44 is installed on the mounting seat 1, and the second linear module 44 is drivingly connected to the second adjustment plate 43 to drive the second adjustment plate 43, the second cam 41 and the second rotating driving 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 direction 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, so as to push the mounting plate 2 to rotate through the rotation of the second cam 41. When the mounting plate 2 is assembled to the mounting seat 1, the second linear module 44 drives the second adjustment plate 43 and the components on the second adjustment plate 43 to move away from the top of the mounting plate 2, so as to facilitate the placement of the mounting plate 2 in the sink 1a.

[0097] Reference Figure 3-Figure 6Furthermore, at least one of the first adjustment structure 3 and the second adjustment structure 4 further includes a locking assembly 5. The sliding of the first adjustment plate 33 or the second adjustment plate 43 is restricted by locking the locking assembly 5. When assembling the mounting plate 2 and the mounting seat 1, by restricting the sliding of the first adjustment plate 33 and the second adjustment plate 43, the first adjustment plate 33 and the second adjustment plate 43 are restricted to the side of the sink 1a, and the position above the sink 1a is vacated, so that it is convenient to assemble the mounting plate 2 equipped with the injection member a onto the mounting seat 1.

[0098] Reference Figure 3-Figure 6 In this embodiment, the first adjustment structure 3 and the second adjustment structure 4 both include a locking assembly 5. The locking assembly 5 includes a locking fitting assembly 51. The locking fitting assembly 51 includes an insertion rod 511 and an elastic fitting block 512, and the insertion rod 511 is fixedly connected to the first adjustment plate 33 or the second adjustment plate 43. The elastic fitting block 512 is fixed on the mounting seat 1, and an insertion groove 512a is provided on the side of the elastic fitting block 512, and the head size of the insertion rod 511 is larger than the rod size of the insertion rod 511. The shape of the insertion groove 512a fits the head of the insertion rod 511, and as the insertion rod 511 slides in the first direction, the head of the insertion rod 511 is inserted into the insertion groove 512a.

[0099] It can be understood that the slot of the insertion slot 512a is closed, and when the head of the insertion rod 511 is inserted into the insertion slot 512a, the elastic deformation of the elastic matching block 512 supports the slot of the insertion slot 512a to be opened. When the head of the insertion rod 511 is inserted into the insertion slot 512a, the slot of the insertion slot 512a restricts the head of the insertion rod 511 from leaving, so as to restrict the sliding of the first adjustment plate 33 and the second adjustment plate 43.

[0100] In this embodiment, the material of the elastic matching block 512 includes plastic.

[0101] Furthermore, the locking assembly 5 also includes a locking bolt 52 , which is threadedly inserted into the insertion rod 511 , and the locking bolt 52 is suitable for tightening against the mounting seat 1 .

[0102] In this way, after the insertion rod 511 forms an insertion fit with the insertion groove 512a, the locking bolt 52 is tightened so that the locking bolt 52 is pressed against the mounting base 1, thereby further limiting the movement of the insertion rod 511 to stably limit the movement of the first adjustment plate 33 or the second adjustment plate 43.

[0103] Reference Figure 1-Figure 3The nozzle automatic adjustment installation mechanism further includes a plurality of clamping structures 7, which are respectively clamped at a plurality of corners of the mounting plate 2, and the mounting plate 2 is clamped and fixed to the mounting seat 1. The mounting plate 2 is clamped by the plurality of clamping structures 7, and the position of the mounting plate 2 relative to the mounting seat 1 is fixed. After the position of the ejector a is automatically adjusted, the position of the ejector a is automatically fixed by fixing the position of the mounting plate 2, and the position of the ejector a is automatically adjusted and fixed. This facilitates the position adjustment and fixation of the ejector a in the printing device.

[0104] The clamping structure 7 is installed on the mounting seat 1, the first adjustment structure 3 or the second adjustment structure 4. In this embodiment, the clamping structure 7 is installed on the first adjustment structure 3 and the second adjustment structure 4. Specifically, the clamping structure 7 is installed on 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 to the top of the mounting plate 2, the mounting plate 2 is clamped and fixed.

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

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

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

[0108] Reference Figure 7 and Figure 8 Optionally, the nozzle automatic adjustment installation mechanism further includes multiple groups of height adjustment structures 8, and multiple corners of the mounting plate 2 are supported by the height adjustment structures 8. The height adjustment structure 8 includes a pad 81, multiple first adjustment bolts 82, and multiple second adjustment bolts 83. The pad 81 is connected to the bottom of the sink 1a of the mounting seat 1 through the first adjustment bolts 82 and the second adjustment bolts 83, and the pad 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 seat 1, and the head of the first adjusting bolt 82 is tightly against the backing plate 81. The second adjusting bolt 83 is threadedly passed through the backing plate 81, and the second adjusting bolt 83 is tightly against the mounting seat 1. A first adjusting bolt 82 and a second adjusting bolt 83 are 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 the multiple pads 81 are consistent. When the 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 piece 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] The embodiment of the present application provides an automatic adjustment and installation mechanism for a nozzle, wherein 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] Among them, the first adjustment structure 3 drives the first cam 31 to rotate through the first rotating driving 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 form, the stroke accuracy is high, and it is easy to accurately adjust the position of the injection member a in the first direction. The second adjustment structure 4 drives the second cam 41 to rotate through the second rotating driving member 42, and the second cam 41 pushes the matching surface 45a in the second direction, and at the same time, the first cam 31 is pressed against the mounting plate 2 in the first direction, so 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, and the length direction of the injection member a is adjusted, so that the multi-directional adjustment of the position of the injection member a on the horizontal plane can be achieved to support the precise splicing of multiple injection members a.

[0114] The position of the ejector a is adjusted by first driving the mounting plate 2 to rotate and adjusting the length direction of the ejector a, and then pushing the mounting plate 2 to move in the first direction, and adjusting the position of the ejector a in the first direction. During the position adjustment of the ejector a, the first rotating driving member 32 drives the first cam 31 to rotate, and the second rotating driving member 42 drives the second cam 41 to rotate. There is no need to manually fine-tune the position of the ejector a gradually. Therefore, when an inkjet printing unit composed of multiple ejectors a is integrated in a printing device, there is no need to remove the inkjet printing unit for adjustment. The position of each ejector a can be directly adjusted in the printing device through the first adjustment structure 3 and the second adjustment structure 4, which not only ensures the adjustment accuracy, but also improves the efficiency of the position adjustment of the ejector a.
