[0035] The nozzle base plate mounting structure in the embodiment of the present application can be threadedly connected through the threaded section 520 of the first locking member 500 and the threaded hole 410 of the second adapter 400 to achieve locking and fixation between the second adapter 400 and the mounting frame 200, and the first polished hole 210 of the mounting frame 200 and the second polished hole 420 of the second adapter 400 respectively form an axial hole cooperation with the polished section 510 of the first locking member 500, which can effectively reduce the gap between the first polished hole 210, the second polished hole 420 and the polished section 510, thereby reducing the position deviation between the nozzle base plate 100 and the mounting frame 200. At the same time, by sequentially setting the first adapter 300 and the second adapter 400 between the nozzle base plate 100 and the mounting frame 200, the first adjusting component 600 is connected between the second adapter 400 and the first adapter 300 and is used to adjust the position of the nozzle base plate 100 along the vertical direction, the second adjusting component 700 is connected between the first adapter 300 and the nozzle base plate 100 and is used to adjust the position of the nozzle base plate 100 along the first direction X, and the third adjusting component 800 is connected between the first adapter 300 and the nozzle base plate 100 and is used to adjust the position of the nozzle base plate 100 along the first direction X. By adjusting the position of the nozzle base plate 100 along the second direction Y, it is only necessary to fine-tune the position between the nozzle base plate 100 and the mounting frame 200 while reducing the initial installation deviation of the nozzle base plate 100, so as to achieve precise positioning of the installation position of the nozzle base plate 100, thereby greatly reducing the number of adapters between the nozzle base plate 100 and the mounting frame 200. The space occupied by the first adapter 300 and the second adapter 400 is greatly reduced compared with the existing structure, and will not occupy the internal installation space of the printing device, so as to reduce the weight of the printing device and reduce the difficulty of adjustment.

[0036] In some embodiments, see Figure 2 The mounting frame 200 further has a countersunk hole 220, which extends from the side of the mounting frame 200 away from the second adapter 400 to the first smooth hole 210, and the first smooth hole 210 extends from the side of the mounting frame 200 toward the second adapter 400 to the countersunk hole 220, and the inner diameter of the countersunk hole 220 is larger than the inner diameter of the first smooth hole 210. The countersunk hole 220 can be used to accommodate the nut of the first locking member 500.

[0037] In some embodiments, see Figure 1 , Figures 4 to 10The nozzle base plate mounting structure includes two mounting racks 200 distributed along the second direction Y, and the first adapter 300 and the second adapter 400 are connected between the two opposite ends of the nozzle base plate 100 and the two mounting racks 200; the second adjustment component 700 is arranged at the first end of the nozzle base plate 100 and connected between the two opposite sides of the nozzle base plate 100 along the first direction X and the corresponding first adapter 300, and the second adjustment component 700 can push the first end of the nozzle base plate 100 to swing relative to the second end along the first direction X; the third adjustment component 800 is connected between the two opposite ends of the nozzle base plate 100 along the second direction Y and the corresponding first adapter 300, and the third adjustment component 800 can push the nozzle base plate 100 to reciprocate in the second direction Y. Among them, the arrangement of the two mounting racks 200, the two first adapters 300 and the two second adapters 400 can ensure the installation stability and symmetry of the opposite ends of the nozzle base plate 100 along the second direction Y.

[0038] In some embodiments, see Figure 5 , Figure 6 , Figures 9 to 11 The first adapter 300 includes a horizontal plate 310, a first vertical plate 320 and two second vertical plates 330, the first vertical plate 320 is vertically connected to the horizontal plate 310, and the two second vertical plates 330 are respectively vertically connected to the horizontal plate 310 and are spaced apart along the first direction X; the end of the nozzle base plate 100 is supported on the horizontal plate 310 and is located between the first vertical plate 320 and the two second vertical plates 330; the first adjustment component 600 is connected between the first vertical plate 320 and the second adapter 400; the second adjustment component 700 is connected between the nozzle base plate 100 and the two second vertical plates 330; the third adjustment component 800 is connected between the nozzle base plate 100 and the two first vertical plates 320. Among them, by dividing the first adapter 300 into a horizontal plate 310, a first vertical plate 320 and two second vertical plates 330, the first adapter 300 can be connected to the second adapter 400 and the nozzle base plate 100 to connect the first adjustment component 600, the second adjustment component 700 and the third adjustment component 800 respectively, so as to realize the position adjustment of the nozzle base plate 100 along the vertical direction, the first direction X and the second direction Y respectively, thereby simplifying the adapter structure between the nozzle base plate 100 and the mounting frame 200.

[0039] Optionally, opposite ends of the first vertical plate 320 along the first direction X are respectively connected to two second vertical plates 330 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, see Figures 4 to 7The first adjustment assembly 600 includes a first adjustment member 610 and a first elastic member 620. The first end of the first adjustment member 610 abuts against the side of the second adapter 400 away from the first adapter 300. The first adjustment member 610 penetrates the second adapter 400. The second end of the first adjustment member 610 is threadedly connected to the first adapter 300. The first elastic member 620 abuts between the first adapter 300 and the second adapter 400. When it is necessary to adjust the position of the nozzle base plate 100 in the vertical direction, the first adjustment member 610 is rotated to adjust the depth of the second end of the first adjustment member 610 being threaded into the first adapter 300, thereby adjusting the distance between the first adapter 300 and the second adapter 400 in the vertical direction, and further adjusting the position of the nozzle base plate 100 in the vertical direction. Specifically, when the depth of the second end thread of the first adjusting member 610 screwed into the first adapter 300 increases, the first elastic member 620 is compressed; when the depth of the second end thread of the first adjusting member 610 screwed into the first adapter 300 decreases, the first elastic member 620 stretches and pushes the first adapter 300 and the second adapter 400 apart, so that the distance between the first adapter 300 and the second adapter 400 increases.

[0042] In some embodiments, see Figure 7 , the second adapter 400 is located above the first adapter 300, and the nut of the first adjusting member 610 abuts against the upper side of the second adapter 400. When the depth of the second end of the first adjusting member 610 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 up, that is, the nozzle bottom plate 100 rises; when the depth of the second end of the first adjusting member 610 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 down, that is, the nozzle bottom plate 100 drops.

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

[0044] In some embodiments, see Figure 4 At least two first adjustment components 600 spaced apart along the first direction X are connected between the first adapter 300 and the second adapter 400, and at least two groups of first adjustment components 600 are provided between each second adapter 400 and the first adapter 300, thereby ensuring the uniformity of the position adjustment of the nozzle base plate 100 along the vertical direction.

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

[0046] In a preferred embodiment, two groups of first adjustment components 600 and two first locking components 900 are connected between the first adapter 300 and the second adapter 400 , and the two first locking components 900 are disposed between the two first adjustment components 600 .

[0047] In some embodiments, see Figure 8 and Fig. 9 The second adjustment component 700 includes a second adjustment member 710 and a second elastic member 720. The second adjustment member 710 is threadedly installed on the first adapter 300 and abuts against one side of the first end of the nozzle base plate 100 along the first direction X. The second elastic member 720 is installed on the other side of the first end of the nozzle base plate 100 along the first direction X and elastically abuts against the first adapter 300 along the first direction X.

[0048] Assume that the second adjusting member 710 and the second elastic member 720 are located at the front side and the rear side respectively, and assume that 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 nozzle base plate 100 along the first direction X, the second adjusting member 710 can be rotated clockwise so that the second adjusting member 710 pushes the first end of the nozzle base plate 100 backward, and the second elastic member 720 is compressed at this time; or the second adjusting member 710 can be rotated counterclockwise so that the second adjusting member 710 moves forward, the second elastic member 720 extends and pushes the first end of the nozzle base plate 100 forward, so that the nozzle base plate 100 swings forward and backward along the first direction to adjust the front and rear position of the nozzle base plate 100, thereby realizing the horizontal adjustment of the nozzle base plate 100 in the second direction Y.

[0049] In some embodiments, a ball is provided at the end of the second adjusting member 710 abutting against the nozzle bottom plate 100, and the second adjusting member 710 abuts against the nozzle bottom plate 100 through the ball, thereby reducing the friction between the second adjusting member 710 and the nozzle bottom plate 100. Optionally, the second adjusting member 710 is a glass ball screw, which is threadedly mounted on the first adapter 300 through the glass ball screw, and abuts against the nozzle bottom plate 100 through the glass ball of the glass ball screw. It can be understood that in other embodiments of the present application, as long as it can be threadedly mounted on the first adapter 300 and a ball or arc portion is provided at the end, it can even be set as a plane for the end surface of the second adjusting member 710 abutting against the nozzle bottom plate 100, and no sole limitation is made here.

[0050] In some embodiments, the second elastic member 720 is a plunger spring, which is a mechanical part with a spring installed inside the screw thread. The depth of the plunger spring threaded into the nozzle base plate 100 can be controlled to adjust the pre-tightening force of the plunger spring on the first adapter 300 and 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 nozzle base plate 100.

[0051] In some embodiments, see Figure 5 and Fig.11 The first end of the nozzle 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 nozzle 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 enables the second adjustment component 700 to adjust the nozzle base plate 100 and move it, and the first elongated hole 110 and the first fastener have a gap along the first direction X, which provides the second adjustment component 700 with an adjustment space for the nozzle base plate 100 along the first direction X. After the position of the nozzle base plate 100 along the first direction X is adjusted by the second adjustment component 700, the first fastener is passed through the first elongated hole 110 and the first mounting hole 311 respectively to lock the nozzle base plate 100 and the first adapter 300 to ensure the connection stability between the nozzle base plate 100 and the first adapter 300.

[0052] In some embodiments, see Figures 4 to 6 and Fig.10The third adjustment component 800 includes a third adjustment member 810 and a third elastic member 820. The third adjustment member 810 is rotatably mounted on 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 mounted on the other end of the nozzle base plate 100 along the second direction Y and abuts against the other first adapter member 300.

[0053] Assuming that 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, causing the nozzle base plate 100 to move right relative to the left first adapter 300, and the third elastic member 820 is compressed; the third adjusting member 810 can also be rotated clockwise or counterclockwise to move the third adjusting member 810 to the right, and the third elastic member 820 is stretched and pushes the nozzle base plate 100 to move to the left.

[0054] Optionally, the third adjustment member 810 can adopt a spiral micrometer, and the position of the nozzle base plate 100 along the second direction Y can be fine-tuned by slowly rotating the spiral micrometer. The second direction Y is the width direction of the printing medium, that is, perpendicular to the direction of movement of the printing medium. When the printing module has multiple nozzles 1100 distributed 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, fine-tuning the position of the nozzle base plate 100 along the second direction Y by using a spiral micrometer can achieve a higher adjustment accuracy and meet actual production needs. It can be understood that in other embodiments of the present application, when the position accuracy of the printing module along the second direction Y is not required to be high, the third adjustment member 810 can also be set as a glass bead screw, which is not the only limitation here.

[0055] In some embodiments, the third elastic member 820 is a plunger spring, which is a mechanical part with a spring installed inside the screw thread. The depth of the plunger spring threaded into the nozzle base plate 100 can be controlled to adjust the pre-tightening force of the plunger spring on the first adapter 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, see Figure 6 and Fig.11The second end of the nozzle base plate 100 has a second elongated hole 120 extending along the second direction Y, the second adapter 400 has a second mounting hole 312, the second fastener 1000 locks the first adapter 300 and the nozzle base plate 100 through the second elongated hole 120 and the second mounting hole 312, and there is a gap between the second fastener 1000 and the second elongated hole 120 in the second direction Y. The second adjustment component 700 is disposed near the end of the nozzle base plate 100 where the first elongated hole 110 is disposed. After the position of the nozzle base plate 100 along the second direction Y is adjusted by the third adjustment component 800, the second fastener 1000 penetrates the second elongated hole 120 and the second mounting hole 312 respectively to lock the nozzle base plate 100 and the first adapter 300, so as to ensure the connection stability between the nozzle base plate 100 and the first adapter 300.

[0057] On the other hand, the present application also provides a printing device, including the above-mentioned nozzle bottom plate mounting structure. Figure 1 The printing device further includes a nozzle 1100 , which is mounted on a nozzle base plate 100 , and a nozzle base plate mounting structure mounts the nozzle 1100 on a mounting frame 200 .

[0058] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
