The counterbore 220 can be used to accommodate the nut of the first locking piece 500.

[0037] In some embodiments, referring to Figure 1 , Figures 4 to 10The nozzle bottom plate mounting structure comprises two mounting racks 200 distributed along the second direction Y, a first adapter 300 and a second adapter 400 are connected between the opposite ends of the nozzle bottom plate 100 and the two mounting racks 200 respectively, a second adjusting assembly 700 is arranged at the first end of the nozzle bottom plate 100 and connected between the opposite sides of the nozzle bottom plate 100 along the first direction X and the corresponding first adapter 300, the second adjusting assembly 700 can push the first end of the nozzle bottom plate 100 to swing along the first direction X relative to the second end, and a third adjusting assembly 800 is connected between the opposite ends of the nozzle bottom plate 100 along the second direction Y and the corresponding first adapter 300, the third adjusting assembly 800 can push the nozzle bottom plate 100 to reciprocate along the second direction Y. The arrangement of the two mounting racks 200, the two first adapters 300 and the two second adapters 400 can ensure the mounting stability and symmetry of the opposite ends of the nozzle bottom plate 100 along the second direction Y.

[0038] In some embodiments, referring to Figure 5 、 Figure 6 、 Figures 9 to 11 The first adapter 300 comprises a transverse plate 310, a first vertical plate 320 and two second vertical plates 330, the first vertical plate 320 is connected perpendicularly to the transverse plate 310, and the two second vertical plates 330 are respectively connected perpendicularly to the transverse plate 310 and arranged at intervals along the first direction X, the end of the nozzle bottom plate 100 is supported on the transverse plate 310 and located between the first vertical plate 320 and the two second vertical plates 330, the first adjusting assembly 600 is connected between the first vertical plate 320 and the second adapter 400, the second adjusting assembly 700 is connected between the nozzle bottom plate 100 and the two second vertical plates 330, and the third adjusting assembly 800 is connected between the nozzle bottom plate 100 and the two first vertical plates 320. By dividing the first adapter 300 into the transverse plate 310, the first vertical plate 320 and the two second vertical plates 330, the first adapter 300 can be connected with the second adapter 400, the nozzle bottom plate 100, the first adjusting assembly 600, the second adjusting assembly 700 and the third adjusting assembly 800 respectively, so as to realize the position adjustment of the nozzle bottom plate 100 along the vertical direction, the first direction X and the second direction Y respectively, and simplify the adapter structure between the nozzle bottom plate 100 and the mounting rack 200.

[0039] Optionally, the opposite ends of the first vertical plate 320 along the first direction X are respectively connected with the two second vertical plates 330, so as to improve the structural stability of the two second vertical plates 330.

[0040] Optionally, the transverse plate 310, the first vertical plate 320 and the two second vertical plates 330 are integrally connected.

[0041] In some embodiments, referring to Figures 4 to 7The first adjusting assembly 600 comprises a first adjusting piece 610 and a first elastic piece 620. The first end of the first adjusting piece 610 abuts against the side of the second adapter 400 away from the first adapter 300. The first adjusting piece 610 penetrates the second adapter 400. The second end of the first adjusting piece 610 is threadedly connected with the first adapter 300. The first elastic piece 620 abuts between the first adapter 300 and the second adapter 400. When it is necessary to adjust the position of the shower nozzle base plate 100 along the vertical direction, the first adjusting piece 610 is rotated to adjust the depth of the second end of the first adjusting piece 610 threadedly screwed into the first adapter 300, so as to adjust the distance between the first adapter 300 and the second adapter 400 along the vertical direction, and further adjust the position of the shower nozzle base plate 100 along the vertical direction. Specifically, when the depth of the second end of the first adjusting piece 610 threadedly screwed into the first adapter 300 increases, the first elastic piece 620 is compressed. When the depth of the second end of the first adjusting piece 610 threadedly screwed into the first adapter 300 decreases, the first elastic piece 620 is stretched and pushes away the first adapter 300 and the second adapter 400, so as to increase the distance between the first adapter 300 and the second adapter 400.

[0042] In some embodiments, referring to Figure 7 The second adapter 400 is located above the first adapter 300. The nut of the first adjusting piece 610 abuts against the upper side of the second adapter 400. When the depth of the second end of the first adjusting piece 610 threadedly screwed into the first adapter 300 increases, the distance between the first adapter 300 and the second adapter 400 decreases, and the first adapter 300 moves upward, i.e. the shower nozzle base plate 100 is raised. When the depth of the second end of the first adjusting piece 610 threadedly screwed into the first adapter 300 decreases, the distance between the first adapter 300 and the second adapter 400 increases, and the first adapter 300 moves downward, i.e. the shower nozzle base plate 100 is lowered.

[0043] In some embodiments, referring to Figure 7 The first elastic piece 620 is a cylindrical spring. The side of the first adapter 300 facing the second adapter 400 is recessed with a first accommodating groove 321. The side of the second adapter 400 facing the first adapter 300 is recessed with a second accommodating groove 430. The cylindrical spring is sleeved on the first adjusting piece 610. The opposite ends of the cylindrical spring are accommodated in the first accommodating groove 321 and the second accommodating groove 430 respectively.

[0044] In some embodiments, referring to Figure 4 At least two first adjusting assemblies 600 are connected between the first adapter 300 and the second adapter 400 and are spaced apart along the first direction X. At least two groups of first adjusting assemblies 600 are arranged between each second adapter 400 and the first adapter 300, so as to ensure the uniformity of the adjustment of the position of the shower nozzle base plate 100 along the vertical direction.

[0045] In some embodiments, referring to Figures 4 to 7 , the second adapter 400 is provided with a first locking member 900, the first locking member 900 is threadedly connected with the second adapter 400, and an axial end of the first locking member 900 abuts against the first adapter 300. After the spacing between the first adapter 300 and the second adapter 400 in the vertical direction is adjusted by the first adjusting assembly 600, the first locking member 900 is rotated to move in the vertical direction until the axial end of the first locking member 900 abuts against the first adapter 300, thereby ensuring the stability of the spacing between the first adapter 300 and the second adapter 400, avoiding loosening of the first adjusting member 610 due to the reaction force of the first elastic member 620, and thereby improving the connection stability of the first adapter 300 and the second adapter 400.

[0046] In a preferred embodiment, two groups of the first adjusting assembly 600 and two first locking members 900 are connected between the first adapter 300 and the second adapter 400, and the two first locking members 900 are arranged between the two groups of the first adjusting assembly 600.

[0047] In some embodiments, referring to Figure 8 and Figure 9 , the second adjusting assembly 700 includes a second adjusting member 710 and a second elastic member 720, the second adjusting member 710 is threadedly mounted on the first adapter 300 and abuts against one side of the first end of the shower head base plate 100 along the first direction X, and the second elastic member 720 is mounted on the other side of the first end of the shower head base plate 100 along the first direction X and elastically abuts against the first adapter 300 along the first direction X.

[0048] When the second adjusting member 710 and the second elastic member 720 are arranged on the front side and the rear side respectively, when the second adjusting member 710 is rotated clockwise, the second adjusting member 710 moves backward, and when the second adjusting member 710 is rotated counterclockwise, the second adjusting member 710 moves forward. When it is necessary to adjust the position of the shower head base plate 100 along the first direction X, the second adjusting member 710 can be rotated clockwise to push the first end of the shower head base plate 100 backward, and at this time the second elastic member 720 is compressed; or the second adjusting member 710 can be rotated counterclockwise to move the second adjusting member 710 forward, the second elastic member 720 extends and pushes the first end of the shower head base plate 100 forward, so that the shower head base plate 100 swings forward and backward along the first direction to adjust the forward and backward positions of the shower head base plate 100, thereby achieving the levelness adjustment of the shower head base plate 100 in the second direction Y.

[0049] In some embodiments, the end of the second adjusting member 710 abutting against the shower head base plate 100 is provided with a ball, and the second adjusting member 710 abuts against the shower head base plate 100 through the ball, so as to reduce the friction between the second adjusting member 710 and the shower head base plate 100. Optionally, the second adjusting member 710 is a ball screw, which is screwed into the first adapter 300 through the ball screw, and abuts against the shower head base plate 100 through the ball of the ball screw. It can be understood that in other embodiments of the present application, as long as the second adjusting member 710 can be screwed into the first adapter 300, and the end is provided with a ball or a circular arc, or even the end surface of the second adjusting member 710 abutting against the shower head base plate 100 is provided as a plane, which is not limited herein.

[0050] In some embodiments, the second elastic member 720 is a plunger spring, which is a mechanical part provided with a spring inside the thread. The depth of the plunger spring screwed into the shower head base plate 100 can be controlled to adjust the pre-tightening force of the plunger spring on the first adapter 300, and to realize the positioning function. It can be understood that in other embodiments of the present application, the second elastic member 720 can also be a cylindrical spring or a spring sheet installed on the shower head base plate 100.

[0051] In some embodiments, referring to Figure 5 and Figure 11 , the first end of the shower head base plate 100 has a first elongated hole 110 extending along the first direction X, the first adapter 300 is provided with a first mounting hole 311, and the first fastener locks the first adapter 300 and the shower head base plate 100 through the first elongated hole 110 and the first mounting hole 311. The first elongated hole 110 and the first fastener have a gap along the first direction X. The first elongated hole 110 allows the second adjusting assembly 700 to still align the first elongated hole 110 and the first mounting hole 311 after adjusting the position of the shower head base plate 100, and the gap between the first elongated hole 110 and the first fastener along the first direction X provides an adjusting space for the second adjusting assembly 700 to adjust the position of the shower head base plate 100 along the first direction X. When the position of the shower head base plate 100 along the first direction X is adjusted by the second adjusting assembly 700, the first fastener is respectively inserted through the first elongated hole 110 and the first mounting hole 311 to lock the shower head base plate 100 and the first adapter 300, so as to ensure the connection stability between the shower head base plate 100 and the first adapter 300.

[0052] In some embodiments, referring to Figures 4 to 6 and Figure 10The third adjusting assembly 800 comprises a third adjusting member 810 and a third elastic member 820. The third adjusting member 810 is rotationally installed at one end of the nozzle base plate 100 along the second direction Y and abuts against one of the first adapter members 300. The third elastic member 820 is installed at the other end of the nozzle base plate 100 along the second direction Y and abuts against the other first adapter member 300.

[0053] When the second direction Y is the left-right direction, the third adjusting member 810 can be rotated clockwise or counterclockwise to move the third adjusting member 810 to the left, thereby moving the nozzle base plate 100 to the right relative to the left first adapter member 300, and the third elastic member 820 is compressed at this time. The third adjusting member 810 can also be rotated clockwise or counterclockwise to move the third adjusting member 810 to the right, thereby stretching the third elastic member 820 and pushing the nozzle base plate 100 to move to the left.

[0054] Optionally, the third adjusting member 810 can be a screw differential scale. The position of the nozzle base plate 100 along the second direction Y can be finely adjusted by slowly rotating the screw differential scale. The second direction Y is the width direction of the printing medium, that is, the direction perpendicular to the movement direction of the printing medium. When the printing module is distributed with a plurality of nozzles 1100 along the second direction Y, the second direction Y is also the expansion direction of the printing medium. In order to avoid white spots or ghosting of the printing medium at the expansion position, it is necessary to ensure the installation accuracy of the printing module along the second direction Y. Therefore, the position of the nozzle base plate 100 along the second direction Y is finely adjusted by the screw differential scale, which can achieve higher adjustment accuracy and meet the actual production requirements. It can be understood that in other embodiments of the present application, when the position accuracy requirement of the printing module along the second direction Y is not high, the third adjusting member 810 can also be a ball screw, which is not limited herein.

[0055] In some embodiments, the third elastic member 820 is a plunger spring. The plunger spring is a mechanical part provided with a spring inside the screw thread. The depth of the plunger spring screwing into the nozzle base plate 100 can be controlled to adjust the pre-tightening force of the plunger spring on the first adapter member 300 and realize the positioning function. It can be understood that in other embodiments of the present application, the third elastic member 820 can also be a cylindrical spring or a spring sheet installed on the nozzle base plate 100.

[0056] In some embodiments, please refer to Figure 6 and Figure 11The second end of the nozzle base plate 100 has a second long hole 120 extending along the second direction Y, the second adapter 400 is provided with a second mounting hole 312, the second fastener 1000 locks the first adapter 300 and the nozzle base plate 100 through the second long hole 120 and the second mounting hole 312, the second fastener 1000 has a gap with the second long hole 120 along the second direction Y, and the second adjusting assembly 700 is arranged close to the end of the nozzle base plate 100 provided with the first long hole 110. When the position of the nozzle base plate 100 along the second direction Y is adjusted through the third adjusting assembly 800, the nozzle base plate 100 and the first adapter 300 are locked through the second fastener 1000 penetrating the second long hole 120 and the second mounting hole 312 respectively, so as to ensure the connection stability between the nozzle base plate 100 and the first adapter 300.

[0057] In another aspect, the embodiment of the present application further provides a printing device comprising the nozzle base plate mounting structure. Figure 1 The printing device further comprises a nozzle 1100 mounted on the nozzle base plate 100, and the nozzle base plate mounting structure mounts the nozzle 1100 on the mounting frame 200.

[0058] The above only describes the preferred embodiment of the present application and is not used to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
