Description

Technical Field

[0001] The present application belongs to the field of printing technology, and more specifically, relates to a printing module and a printing device. Background Art

[0002] The printing module is the core module of the digital printing device, which generally includes a mounting plate and a plurality of nozzles mounted on the mounting plate. The plurality of nozzles are used to cooperate with each other to print colorful patterns on the printing medium. The existing nozzles are usually fixed on the mounting plate. When the resolution of the nozzle printing needs to be increased, the nozzles are connected in series to the original printing module to increase the insertion points (specifically, the nozzles are arranged and installed along the moving direction of the printing medium so that the ink dots of the serial nozzles and the ink dots of the fixed nozzles are misaligned in the moving direction of the printing medium), and an adjustment component is set to adjust the position of the serial nozzles. However, the existing structure does not have a serial connection of nozzles based on expansion (i.e., adding nozzles perpendicular to the printing medium direction). Since the fixed nozzles and the serial connection nozzles need to strictly meet the preset distance during expansion, otherwise the preset distance If the size is too large or too small, blank spaces or black edges will be generated after printing, thus affecting the printing effect. Therefore, the distance between the expansion nozzle and the fixed nozzle is usually extremely small. Since the medium or nozzle of the resolution cascade nozzle will move during the printing process, the ink dots of the resolution cascade nozzle can be inserted during the movement of the nozzle or the medium, commonly known as insertion points. Therefore, there is no requirement for the space between the resolution cascade nozzle and the fixed nozzle. There is enough space in this direction to install the adjustment component. The structure of the adjustment component is usually large, and the adjustment component used for the resolution cascade nozzle cannot be used for the adjustment of the expansion nozzle. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a printing module and a printing device to solve the technical problem in the prior art that the adjustment component used for the resolution series nozzle cannot be used for the adjustment of the expansion nozzle.

[0005] In some embodiments, the first adjustment component includes a swinging member rotatably provided on the mounting plate, and one end of the nozzle along the first direction is provided with a connecting portion for mounting the nozzle on the mounting plate; the swinging member is located between two adjacent nozzles in the second direction and partially extends into between two adjacent nozzles in the first direction to be connected to the connecting portion of the nozzle, and the swinging member can push the connecting portion in the forward and reverse directions along the first direction when rotating clockwise and counterclockwise, respectively.

[0006] In some embodiments, the swing member includes two pushing arms distributed along the first direction, and the connecting part is located between the two pushing arms. When the swing member rotates clockwise and counterclockwise, the connecting part can be pushed by the two pushing arms respectively to adjust the position of the nozzle along the first direction.

[0007] In some embodiments, the printing module further includes a first locking member, and the first locking member is used to lock the connecting portion to the mounting plate.

[0008] In some embodiments, the first adjustment component further includes a driving member movably disposed on the mounting plate, and the driving member can drive the swinging member to rotate clockwise and counterclockwise.

[0009] In some embodiments, the driving member includes a first eccentric member, which is rotatably arranged on the mounting plate; the swinging member includes two mating arms, and driving the first eccentric member to rotate can push the two mating arms respectively to make the swinging member rotate clockwise and counterclockwise.

[0010] In some embodiments, the swing member includes a first swing part and a second swing part connected along the second direction, the width of the first swing part along the first direction is smaller than the width of the second swing part along the first direction; the second swing part is arranged between the two adjacent nozzles along the second direction, the first swing part is inserted between the two adjacent nozzles along the first direction, and the first swing part is used to drive the connecting part.

[0011] In some embodiments, the second adjustment assembly includes a second eccentric member and an elastic member, the second eccentric member and the elastic member are respectively abutted against two opposite sides of the nozzle along the second direction, and the second eccentric member is rotatably disposed on the mounting plate.

[0012] In some embodiments, the printing module further includes a positioning post and a positioning hole, the positioning post can be inserted into the positioning hole, and an outer peripheral wall of the positioning post and an inner peripheral wall of the positioning hole have a gap along the first direction and the second direction;

[0013] The positioning column is arranged on the mounting plate, and the positioning hole is arranged on the nozzle;

[0014] Alternatively, the positioning column is arranged on the nozzle, and the positioning hole is arranged on the mounting plate.

[0015] On the other hand, the present application also provides a printing device, including a mounting frame and the above-mentioned printing module installed on the mounting frame.

[0016] The beneficial effects of the printing module and printing device provided by the present application are as follows: by distributing at least two mounting positions for installing nozzles on the mounting plate along the first direction and the second direction, different numbers of nozzles can be selected to be installed on the mounting plate along the second direction according to the printing resolution requirements.

DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0027] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0028] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0030] See also Figure 1 and Figure 2 , the printing module 1 provided in the embodiment of the present application is now described.

[0031] The printing module 1 includes a mounting plate 100 and a plurality of nozzles 200 mounted on the mounting plate 100. The mounting plate 100 is provided with at least two mounting positions for mounting the nozzles 200 along a first direction X and a second direction Y. The second direction Y is set as the moving direction of the printing medium. The first direction X is perpendicular to the second direction Y. The printing module 1 also includes a first adjustment component 300 and a second adjustment component 400. The first adjustment component 300 is arranged between two adjacent nozzles 200 in the second direction Y and cooperates with the end of the nozzle 200 along the first direction X. The first adjustment component 300 is used to adjust the position of the nozzle 200 along the first direction X. The second adjustment component 400 is arranged between two adjacent nozzles 200 in the second direction Y and adjusts the position of the nozzle 200 along the second direction Y.

[0032] Among them, the second direction Y is set as the moving direction of the printing medium. When the nozzle 200 is connected in series along the second direction Y, the resolution of the printing of the nozzle 200 can be increased. The first direction X is perpendicular to the second direction Y. The first direction X is the width direction of the printing medium. When the nozzle 200 is connected in series along the first direction X, the expansion requirement can be achieved. In addition, it should be noted that the connection of the nozzle 200 in series along the first direction X is to expand the printing width of the entire printing module 1 along the first direction X. Therefore, it is necessary to ensure that all the nozzle holes after the connection are distributed at equal intervals, that is, the first spacing between two adjacent nozzle holes in adjacent nozzles 200 can be equal to the second spacing between two adjacent nozzle holes in the same nozzle 200. When the first spacing is greater than the second spacing, white edges will appear on the printing medium (that is, some places are not printed); when the first spacing is less than the second spacing, the screen overlap will appear on the printing medium. In the embodiment of the present application, by arranging the first adjustment component 300 between two adjacent nozzles 200 in the second direction Y and cooperating with the end of the nozzle 200 along the first direction X, the installation of the first adjustment component 300 will not occupy the space between the adjacent nozzles 200 in the first direction X. When expanding the width, it is only necessary to make the first spacing of the first nozzle holes of the two adjacent nozzles 200 along the first direction X (each nozzle 200 has many nozzle holes, and the multiple nozzle holes are arranged in an array) equal to the second spacing of the two adjacent nozzle holes in the same nozzle 200. The second adjustment component 400 is arranged between the two adjacent nozzles in the second direction Y to achieve the adjustment of the nozzle in the second direction Y. The second adjustment component 400 can directly adjust the nozzle 200 in the second direction Y. The combined adjustment method of the first adjustment component 300 and the second adjustment component 400 can simplify the adjustment steps of the entire printing module for the nozzle while meeting the adjustment requirements, thereby ensuring the quality of the printed image on the basis of achieving resolution adjustment and / or expansion, so that the printing module and the printing device can be compatible with different printing scenarios and have good compatibility.

[0033] Optionally, the mounting plate 100 has three mounting positions distributed along the first direction X, so that one, two or three nozzles 200 can be installed on the mounting plate 100 along the first direction X to meet the printing requirements of printing media of different sizes. It can be understood that in other embodiments of the present application, the mounting plate 100 may also have two, four or more mounting positions along the first direction X, which is not limited here.

[0034] Optionally, the mounting plate 100 has two mounting positions distributed along the second direction Y, so that one or two nozzles 200 can be installed on the mounting plate 100 along the second direction Y to meet different printing resolution requirements. It can be understood that in other embodiments of the present application, the mounting plate 100 may have three, four or more mounting positions along the second direction Y, which is not limited here.

[0035] In some embodiments, the first adjustment component 300 may be connected to one of the ends of the nozzle 200 along the first direction X, and the first adjustment component 300 is used to push one of the ends of the nozzle 200 in the forward direction and the reverse direction of the first direction X respectively to adjust the position of the nozzle 200 along the first direction X, wherein, for the convenience of description, the two opposite directions of the first direction X are referred to as the forward direction and the reverse direction. With the above arrangement, it is only necessary to arrange the first adjustment component 300 at one of the ends of the nozzle 200 along the first direction X to adjust the position of the nozzle 200 along the first direction X, and there is no need to arrange adjustment structures at both opposite ends of the nozzle 200 along the first direction X, thereby reducing the space occupied by the first adjustment component 300 along the first direction X, simplifying the structure, and saving costs.

[0036] In some embodiments, see Figures 2 to 4 The first adjustment component 300 includes a swinging member 310 rotatably disposed on the mounting plate 100, and one end of the nozzle 200 in the first direction X is provided with a connecting portion 221 for mounting the nozzle 200 on the mounting plate 100; the swinging member 310 is located between two adjacent nozzles 200 in the second direction Y and partially extends between two adjacent nozzles 200 in the first direction X to be connected to the connecting portion 221 of the nozzle 200, and the swinging member 310 can push the connecting portion 221 in the positive direction and reverse direction of the first direction X respectively when rotating clockwise and counterclockwise. In this embodiment, by rotating the swing member 310 to drive the nozzle 200 to move, the rotational force of the swing member 310 can be converted into a force that drives the nozzle 200 to move in the first direction X, so that the first adjustment component 300 can adjust the position of the nozzle 200 in the first direction X, and the swing member 310 rotates to drive the nozzle 200 to move horizontally in the first direction X, that is, through the lever principle, the nozzle 200 can be easily and effectively adjusted in the first direction X. In addition, the connection part 221 for installation of the nozzle 200 itself is connected to the swing member 310, so that the connection between the swing member 310 and the nozzle does not occupy space outside the nozzle 200.

[0037] Specifically, the swing member 310 can push the connection part 221 to make the nozzle 200 slide in the positive direction of the first direction X when it rotates clockwise, and can push the connection part 221 to make the nozzle 200 slide in the reverse direction of the first direction X when it rotates counterclockwise.

[0038] It should be noted that the clockwise direction and counterclockwise direction here are for the convenience of describing the rotation of the swing member 310 in two opposite directions. Here, only two opposite rotation directions are limited, and they are not necessarily clockwise or counterclockwise. Similarly, the positive direction of the first direction X and the direction of the first direction X are also for the convenience of describing the two reverse adjustment positions of the nozzle 200 along the first direction X. Here, only two relative movement directions are limited, and they are not necessarily forward or reverse. It should also be noted that in the present application, the positive and reverse directions of the first direction X need to be distinguished only when it is necessary to distinguish the position adjustment direction of the nozzle 200. When no distinction is required, they can be directly referred to as the first direction X.

[0039] In the embodiment of the present application, the swinging member 310 cooperates with the connecting portion 221, and the connecting portion 221 can be pushed to slide in the positive or reverse direction along the first direction X by rotating the swinging member 310, so as to achieve the position adjustment of the nozzle 200 along the first direction X. It is not necessary to respectively set two swinging members 310 at the opposite ends of the nozzle 200 along the first direction X to respectively push the nozzle 200 to slide in the positive and reverse directions along the first direction X, thereby reducing the occupied space of the first adjustment component 300 between two adjacent nozzles 200, so that even if multiple nozzles 200 are set along the first direction X, the first spacing between adjacent nozzle holes between adjacent nozzles 200 can also be achieved with the second spacing between two adjacent nozzle holes in the nozzle 200, thereby ensuring the printing quality of the printing module 1. It can be understood that in other embodiments of the present application, the swinging members 310 can also be respectively set at the opposite ends of the nozzle 200 along the first direction X, and the two swinging members 310 can respectively push the nozzle 200 to slide in the positive or reverse direction along the first direction X, so as to achieve the position adjustment of the nozzle 200 along the first direction X.

[0040] In some embodiments, see Figure 3 and Figure 4 The swing member 310 includes two pushing arms 3111 distributed along the first direction X, and the connecting portion 221 is located between the two pushing arms 3111. When the swing member 310 rotates clockwise and counterclockwise, the connecting portion 221 can be pushed by the two pushing arms 3111 respectively to adjust the position of the nozzle 200 along the first direction X.

[0041] Specifically, when the swing member 310 rotates clockwise, one of the pushing arms 3111 can push the connecting part 221 to make the nozzle 200 move in the positive direction of the first direction X; when the swing member 310 rotates counterclockwise, the other pushing arm 3111 can push the connecting part 221 to make the nozzle 200 move in the reverse direction of the first direction X.

[0042] In this embodiment, by arranging the connection part 221 between the two pushing arms 3111, the two pushing arms 3111 can respectively push the connection part 221 to move in different directions, without arranging two swinging members 310 to respectively push the connection part 221. It can be understood that in other embodiments of the present application, the connection part 221 can also be pushed respectively by two swinging members 310.

[0043] In some embodiments, the two pushing arms 3111 are arranged opposite to each other and spaced apart, that is, flush with each other, along the first direction X. It is understandable that in other embodiments of the present application, the two pushing arms 3111 may be distributed along the first direction X and staggered in the vertical direction.

[0044] In some embodiments, the printing module 1 further includes a first locking member (not shown), which is used to lock the connection portion 221 to the mounting plate 100. When the position of the nozzle 200 needs to be adjusted, the first locking member can be loosened so that the swing member 310 can be driven to rotate to push the connection portion 221 to adjust the position of the nozzle 200; when the position of the nozzle 200 is adjusted, the connection portion 221 is locked to the mounting plate 100 by the first locking member to ensure the safety of the nozzle 200.

[0045] For details, please refer to Figure 4 , the mounting plate 100 has a first mounting hole 110, the connecting portion 221 has a second mounting hole 2211, and the first locking member sequentially penetrates the second mounting hole 2211 and the first mounting hole 110 to lock the connecting portion 221 to the mounting plate 100. Specifically, in order to adjust the position of the connecting portion 221 on the mounting plate 100, the first mounting hole 110 is configured to have a gap with the first locking member along the first direction X, and the second mounting hole 2211 is configured to match the first locking member, so that after the position of the mounting portion 421 is adjusted, the first locking member can still be inserted into the first mounting hole 110 to lock the connecting portion 221.

[0046] In some embodiments, the first adjustment assembly 300 further includes a driving member movably disposed on the mounting plate 100, and the driving member can drive the swing member 310 to rotate clockwise or counterclockwise. The provision of the driving member facilitates the rotation of the swing member 310 and reduces the difficulty of rotating the swing member 310. It can be understood that in other embodiments of the present application, the driving member may not be provided, and the swing member 310 may be directly manually pushed to rotate the swing member 310 clockwise or counterclockwise.

[0047] In some embodiments, see Figure 3 and Figure 4The driving member includes a first eccentric member 320, which is rotatably arranged on the mounting plate 100. The swinging member 310 includes two matching arms 3121. Driving the first eccentric member 320 to rotate can push the two matching arms 3121 respectively, so that the swinging member 310 rotates clockwise and counterclockwise. Among them, through the arrangement of the first eccentric member 320, the positive and negative eccentric rotations of the first eccentric member 320 can drive the two matching arms 3121 respectively, and there is no need to set two driving members to drive the two matching arms 3121 respectively, so the driving is simple. In addition, the rotation of the first eccentric member 320 can also be achieved by using a special tool, which reduces the difficulty of rotating the first eccentric member 320.

[0048] For details, please refer to Figure 3 The two mating arms 3121 are arranged opposite to each other and at intervals along the first direction X. The first eccentric member 320 is rotatably arranged between the two mating arms 3121. When the first eccentric member 320 rotates forward and reverse, it can push the two mating arms 3121 respectively, thereby driving the swing member 310 to rotate clockwise or counterclockwise.

[0049] For details, please refer to Figure 3 The first eccentric member 320 is provided with a matching opening 321. When the first eccentric member 320 needs to be rotated, a special tool can be used to form a plug-in fit with the matching opening 321 to drive the first eccentric member 320 to rotate, thereby reducing the difficulty of operation. At the same time, the space occupied by the first eccentric member 320 can also be reduced.

[0050] In some embodiments, the first adjustment assembly 300 further includes a second locking member, and the second locking member is used to lock the adjusted first eccentric member 320 to the mounting plate 100. For details, please refer to Figure 4 The mounting plate 100 has a third mounting hole 120 , the first eccentric member 320 has a fourth mounting hole 322 extending axially therethrough, and the second locking member passes through the third mounting hole 120 and the fourth mounting hole 322 respectively to lock the first eccentric member 320 to the mounting plate 100 .

[0051] Specifically, the first eccentric member 320 includes a first rotating portion 323 and a first eccentric portion 324 connected in the axial direction, the first rotating portion 323 is cylindrical, and the first eccentric portion 324 is an eccentric structure eccentrically arranged relative to the central axis of the first rotating portion 323. The mounting plate 100 has a first matching hole 130, and the first rotating portion 323 is rotatably matched with the first matching hole 130 to realize the rotation of the first eccentric member 320 on the mounting plate 100.

[0052] In some embodiments, see Figure 3, the swing member 310 includes a first swing portion 311 and a second swing portion 312 connected along the second direction Y, the width of the first swing portion 311 along the first direction X is smaller than the width of the second swing portion 312 along the first direction X; the second swing portion 312 is arranged between two adjacent nozzles 200 along the second direction Y, the first swing portion 311 is inserted between two adjacent nozzles 200 along the first direction X, and the first swing portion 311 is used to drive the connection portion 221. In this embodiment, the second swing portion 312 is larger than the first swing portion 311, so that when the first eccentric member 320 is used to drive the second swing portion 312 to rotate the swing member 310, the first eccentric member 320 can be larger in size, so that the first eccentric member 320 can rotate a smaller angle to meet the swing member 310 to drive the connection portion 221 to adjust the position in the second direction X, thereby improving the adjustment efficiency of the nozzle 200 in the second direction X.

[0053] For details, please refer to Figure 3 The two push arms 3111 are arranged at one end of the first swing part 311 away from the second swing part 312, and the two matching arms 3121 are arranged at one end of the second swing part 312 away from the first swing part 311. When the first eccentric member 320 rotates, the two matching arms 3121 can be pushed respectively to rotate the swing member 310. The rotation of the swing member 310 can push the connecting part 221 respectively through the two push arms 3111, thereby realizing the position adjustment of the nozzle 200 along the first direction X.

[0054] Optionally, see Figure 3 and Figure 4 The swinging member 310 has a rotation hole 313 formed at the connection between the first swinging portion 311 and the second swinging portion 312. The mounting plate 100 is mounted with a fixing member 330, and the rotation hole 313 is sleeved on the fixing member 330, so that the swinging member 310 can swing on the mounting plate 100.

[0055] Optionally, the first swing portion 311 and the second swing portion 312 are integrally connected.

[0056] In some embodiments, see Figure 2 and Figure 3The nozzle 200 includes a nozzle body 210 and ink receiving parts 220 disposed at opposite ends of the nozzle body 210 along the first direction X, and the two ink receiving parts 220 are staggered along the second direction Y. When two adjacent nozzles 200 are spaced apart along the first direction X, the first swinging part 311 is inserted between the nozzle body 210 of one nozzle 200 and the ink receiving part 220 of the other nozzle 200. In this nozzle structure, when the nozzles are expanded and spliced, the ink receiving part 220 basically occupies most of the space between the adjacent nozzles 200 in the second direction Y. The design of the first adjustment component 300 of this embodiment is applied to such nozzle splicing, and its applicability in structural scenarios with extremely limited space is more significant.

[0057] In some embodiments, see Figure 2 and Figure 5 The second adjustment assembly 400 includes a second eccentric member 410 and an elastic member 420, which are respectively abutted against opposite sides of the spray head 200 along the second direction Y, and the second eccentric member 410 is rotatably disposed on the mounting plate 100. Specifically, when the second eccentric member 410 rotates clockwise or counterclockwise, it can push the spray head 200 to move along the second direction Y. When the second eccentric member 410 rotates clockwise, the spray head 200 can move toward the elastic member 420 along the second direction Y, squeezing the elastic member 420, and the elastic member 420 accumulates elastic force; when the second eccentric member 410 rotates counterclockwise, the spray head 200 can be pushed by the compression elastic force of the elastic member 420 to move away from the elastic member 420, thereby realizing the position adjustment of the spray head 200 along the second direction Y. In this embodiment, the second eccentric member 410 and the elastic member 420 can be respectively arranged between two adjacent nozzles 200 along the second direction Y, wherein, since the second direction Y is the moving direction of the printing module 1, the nozzle hole spacing between two adjacent nozzles 200 along the second direction Y is not required, and the spacing of the nozzles 200 along the second direction Y can be made larger to facilitate the installation of the second eccentric member 410 and the elastic member 420. It can be understood that in other embodiments of the present application, two second eccentric members 410 can also be respectively arranged on opposite sides of the nozzle 200 along the second direction Y, which is not limited here.

[0058] In some embodiments, see Figure 5 The second eccentric member 410 includes a second rotating portion 411 and a second eccentric portion 412 connected in the axial direction, the second rotating portion 411 is cylindrical, and the second eccentric portion 412 is an eccentric structure eccentrically arranged relative to the central axis of the second rotating portion 411. The mounting plate 100 has a second matching hole 140, and the second rotating portion 411 is rotatably arranged in the second matching hole 140 to realize the rotation of the second eccentric member 410 on the mounting plate 100.

[0059] In addition, after the second eccentric member 410 is rotated, it is locked to the mounting plate 100 by the third fastener. And the second eccentric member 410 can also be provided with a matching opening 321 to achieve matching driving with a special tool.

[0060] In some embodiments, see Figure 5 The elastic member 420 includes a spring sheet, which includes a mounting portion 421 and an elastic portion 422, and the mounting portion 421 and the elastic portion 422 form an angle with each other. The mounting plate 100 is installed with a mounting column 430, the mounting portion 421 is installed on the mounting column 430, and the elastic portion 422 abuts against the nozzle 200. The setting of the mounting column 430 can install the elastic portion 422 at a certain height position of the mounting plate 100, so that the abutting position of the elastic portion 422 against the nozzle 200 is opposite to the abutting position of the second eccentric member 410 against the nozzle 200.

[0061] In some embodiments, see Figure 2 and Figure 6 The printing module 1 further includes a positioning column 150 and a positioning hole 222. The positioning column 150 can be inserted into the positioning hole 222. The outer peripheral wall of the positioning column 150 and the inner peripheral wall of the positioning hole 222 have a gap along the first direction X and the second direction Y. The positioning column 150 is arranged on the mounting plate 100, and the positioning hole 222 is arranged on the nozzle 200; or, the positioning column 150 is arranged on the nozzle 200, and the positioning hole 222 is arranged on the mounting plate 100. During assembly, the nozzle 200 can be initially positioned on the mounting plate 100 by the positioning column 150 and the positioning hole 222 to reduce the assembly difficulty of the nozzle 200, and then the position of the nozzle 200 along the first direction X and the second direction Y is adjusted by the first adjustment component 300 and the second adjustment component 400 to achieve fine adjustment of the position of the nozzle 200.

[0062] In some specific embodiments, see Figure 6 , the positioning column 150 is formed on the mounting plate 100, and the positioning hole 222 is formed on the nozzle 200. The cross section of the positioning column 150 is circular, the positioning hole 222 is square, and the side length of the positioning hole 222 is greater than the diameter of the positioning column 150, so that there is a gap between the outer peripheral wall of the positioning column 150 and the inner peripheral wall of the positioning hole 222 along the first direction X and the second direction Y. It can be understood that in other embodiments of the present application, the positioning column 150 can also be set to a square shape and the positioning hole 222 can be square; or the positioning column 150 can be set to a square shape and the positioning hole 222 can be circular; or the positioning column 150 can be set to a circular shape and the positioning hole 222 can be circular.

[0063] In some embodiments, see Figure 2 and Figure 6A heating sheet 500 is attached to the mounting plate 100 and is disposed around each nozzle 200. The heating sheet 500 is used to preheat the nozzle 200 to adapt to inkjet printing operations that require temperature, such as UV ink.
