Description

TECHNICAL FIELD

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

[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 to print a variety of patterns on the printing medium. The existing nozzle is usually fixed on the mounting plate. When it is necessary to increase the resolution of the nozzle printing, the nozzle is connected to the original printing module to increase the insertion point (specifically, the nozzle is arranged and installed along the moving direction of the printing medium, and the ink dots of the connected nozzle and the ink dots of the fixed nozzle are staggered in the moving direction of the printing medium), and an adjusting assembly is arranged to adjust and position the position of the connected nozzle. However, the existing structure does not connect the nozzle based on the expansion (i.e. add the nozzle perpendicular to the printing medium direction), and because the fixed nozzle and the connected nozzle need to strictly meet the preset distance during expansion, otherwise the preset distance is too large or too small, which will cause blank or black edge after printing, thereby affecting the printing effect. Therefore, the spacing between the expansion nozzle and the fixed nozzle is usually extremely small. Because the resolution of the connected nozzle can be inserted during the printing process of the medium or the nozzle, the ink dots of the resolution of the connected nozzle are inserted, commonly known as insertion point. Therefore, the space between the resolution of the connected nozzle and the fixed nozzle is not required. There is enough space to install the adjusting assembly in this direction. The structure of the adjusting assembly is usually large, and the adjusting assembly applied to the resolution of the connected nozzle cannot be applied to the adjustment of the expansion nozzle. CONTENT OF THE UTILITY MODEL

[0003] The purpose of the embodiment of the present application is to provide a printing module and a printing device to solve the technical problem that the adjusting assembly applied to the resolution of the connected nozzle cannot be applied to the adjustment of the expansion nozzle in the prior art.

[0004] To achieve the above-mentioned purpose, the technical scheme adopted by the present application is to provide a printing module, which includes a mounting plate and a plurality of nozzles mounted on the mounting plate. The mounting plate is distributed with at least two mounting positions for mounting the nozzles along the first direction and the second direction. The second direction is arranged as the moving direction of the printing medium, and the first direction is perpendicular to the second direction. The printing module further includes a first adjusting assembly and a second adjusting assembly. The first adjusting assembly is arranged between the adjacent two nozzles in the second direction and cooperates with the end of the nozzle along the first direction. The first adjusting assembly is used to adjust the position of the nozzle along the first direction. The second adjusting assembly is arranged between the adjacent two nozzles in the second direction and adjusts the position of the nozzle along the second direction.

[0005] In some embodiments, the first adjusting assembly comprises a swing member rotatably arranged on the mounting plate, and the spray head is provided with a connecting portion at one end of the first direction for mounting the spray head on the mounting plate; the swing member is located between two adjacent spray heads in the second direction and partially extends into between two adjacent spray heads in the first direction to connect with the connecting portion, and the swing member can push the connecting portion in the positive direction and the reverse direction of the first direction when rotated clockwise and counterclockwise, respectively.

[0006] In some embodiments, the swing member comprises two pushing arms distributed along the first direction, and the connecting portion is located between the two pushing arms; the swing member can push the connecting portion through the two pushing arms when rotated clockwise and counterclockwise, respectively, to adjust the position of the spray head along the first direction.

[0007] In some embodiments, the spray printing module further comprises a first locking member for locking the connecting portion on the mounting plate.

[0008] In some embodiments, the first adjusting assembly further comprises a driving member movably arranged on the mounting plate, and the driving member can push the swing member to rotate clockwise and counterclockwise.

[0009] In some embodiments, the driving member comprises a first eccentric member rotatably arranged on the mounting plate; the swing member comprises two cooperating arms, and driving the first eccentric member to rotate can push the two cooperating arms to rotate the swing member clockwise and counterclockwise, respectively.

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

[0011] In some embodiments, the second adjusting assembly comprises a second eccentric member and an elastic member, the second eccentric member and the elastic member abut on opposite sides of the spray head along the second direction, respectively, and the second eccentric member is rotatably arranged on the mounting plate.

[0012] In some embodiments, the spray printing module further comprises a positioning column and a positioning hole, the positioning column can be inserted into the positioning hole, and the outer peripheral wall of the positioning column and the inner peripheral wall of the positioning hole have gaps 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] In another aspect, the application also provides a printing device, comprising a mounting frame and the above-mentioned nozzle printing module mounted on the mounting frame.

[0016] The nozzle printing module and the printing device provided by the application have the beneficial effects that: by arranging at least two mounting positions for mounting the nozzle on the mounting plate in the first direction and the second direction, different numbers of nozzles can be mounted on the mounting plate in the second direction according to the printing resolution requirement, the orifices of the nozzles distributed in the second direction are arranged staggered in the first direction during mounting, and the resolution of the nozzle printing module can be realized by the nozzle stringing; different numbers of nozzles can also be mounted on the mounting plate in the first direction according to the printing page requirement, so as to match the printing medium of different sizes in the first direction and realize the expansion effect. In addition, the first adjusting assembly is arranged between the two adjacent nozzles in the second direction and cooperates with the end of the nozzle in the first direction to realize the adjustment of the nozzle in the first direction. In this mounting mode, the installation of the first adjusting assembly does not occupy the space between the adjacent nozzles in the first direction, and therefore the first spacing of the first orifice of each nozzle of the adjacent two nozzles in the first direction after the nozzle stringing only needs to satisfy the second spacing of the adjacent two orifices in the same nozzle. The second adjusting assembly is arranged between the two adjacent nozzles in the second direction to realize the adjustment of the nozzle in the second direction. The second adjusting assembly can directly adjust the nozzle in the second direction. The combination of the first adjusting assembly and the second adjusting assembly can simplify the adjustment steps of the nozzle printing module to the nozzle under the condition of meeting the adjustment requirement, and further ensure the printing image quality on the basis of realizing the resolution adjustment and / or expansion, so that the nozzle printing module and the printing device can be compatible with different printing scenes and have good compatibility.

Therefore, the features defined with "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the application, the meaning of "multiple" is two or more, unless otherwise explicitly and specifically limited.

[0030] Please refer to Figure 1 and Figure 2 , the present application will be described.

[0031] The inkjet module 1 comprises a mounting plate 100 and a plurality of nozzles 200 mounted on the mounting plate 100, the mounting plate 100 is distributed with at least two mounting positions for mounting the nozzles 200 along the first direction X and the second direction Y, the second direction Y is set as the moving direction of the printing medium, and the first direction X is perpendicular to the second direction Y; the inkjet module 1 further comprises a first adjusting assembly 300 and a second adjusting assembly 400, the first adjusting assembly 300 is arranged between the adjacent two nozzles 200 along the second direction Y and cooperates with the end of the nozzles 200 along the first direction X, the first adjusting assembly 300 is used to adjust the position of the nozzles 200 along the first direction X, and the second adjusting assembly 400 is arranged between the adjacent two nozzles 200 along the second direction Y and adjusts the position of the nozzles 200 along the second direction Y.

[0032] The second direction Y is arranged as the moving direction of the printing medium, and when the printheads 200 are connected in series along the second direction Y, the resolution of the printing by the printheads 200 can be increased. The first direction X is perpendicular to the second direction Y, and the first direction X is the width direction of the printing medium, and when the printheads 200 are connected in series along the first direction X, the expansion requirement can be met. In addition, it should be noted that the connection of the printheads 200 along the first direction X is to expand the printing range of the entire printing module 1 along the first direction X, and therefore it is necessary to ensure that all the ejection orifices are distributed at equal intervals after the connection, that is, the first interval between two adjacent ejection orifices in adjacent printheads 200 is equal to the second interval between two adjacent ejection orifices in the same printhead 200. When the first interval is greater than the second interval, white edges (that is, some places are not printed) will appear on the printing medium; when the first interval is less than the second interval, the phenomenon of image overlap will appear on the printing medium. In the embodiment of the present application, the first adjusting assembly 300 is arranged between two adjacent printheads 200 along the second direction Y and cooperates with the end of the printhead 200 along the first direction X, so that the installation of the first adjusting assembly 300 does not occupy the space between the adjacent printheads 200 along the first direction X, and when expanding, as long as the first interval between the first ejection orifice of each printhead 200 (each printhead 200 has a plurality of ejection orifices arranged in an array) along the first direction X meets the requirement of being equal to the second interval between two adjacent ejection orifices in the same printhead 200, the second adjusting assembly 400 is arranged between two adjacent printheads along the second direction Y to realize the adjustment of the printheads along the second direction Y, and the second adjusting assembly 400 can directly adjust the printheads 200 along the second direction Y. The combined adjustment mode of the first adjusting assembly 300 and the second adjusting assembly 400 can simplify the adjustment steps of the entire printing module to the printheads under the condition of meeting the adjustment requirement, and further can ensure the image quality on the basis of realizing the resolution adjustment and / or expansion, so that the printing module and the printing device can be compatible with different printing scenes, and the compatibility is good.

[0033] Optionally, the mounting plate 100 is distributed with three mounting positions along the first direction X, so that one, two or three printheads 200 can be mounted on the mounting plate 100 along the first direction X to meet the printing requirement of the printing medium of different sizes. It can be understood that in other embodiments of the present application, the mounting positions of the mounting plate 100 along the first direction X can also be two, four or more than four, which is not limited here.

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

[0035] In some embodiments, the first adjusting assembly 300 can be connected with one end of the spray head 200 along the first direction X, and the first adjusting assembly 300 is used to push one end of the spray head 200 along the positive direction and the reverse direction of the first direction X respectively to adjust the position of the spray head 200 along the first direction X. For the convenience of description, the two opposite directions of the first direction X are called the positive direction and the reverse direction. The above arrangement only needs to set the first adjusting assembly 300 at one end of the spray head 200 along the first direction X, so as to realize the adjustment of the position of the spray head 200 along the first direction X, without the need to set adjusting structures at the opposite two ends of the spray head 200 along the first direction X, thereby reducing the occupied space of the first adjusting assembly 300 along the first direction X, and also simplifying the structure and saving the cost.

[0036] In some embodiments, referring to Figures 2 to 4 , the first adjusting assembly 300 comprises a swing piece 310 rotatably arranged on the mounting plate 100, and one end of the spray head 200 along the first direction X is provided with a connecting part 221 for mounting the spray head 200 on the mounting plate 100; the swing piece 310 is located between the adjacent two spray heads 200 along the second direction Y and partially extends into the adjacent two spray heads 200 along the first direction X to connect with the connecting part 221 of the spray head 200, and the swing piece 310 can push the connecting part 221 along the positive direction and the reverse direction of the first direction X respectively when the swing piece 310 rotates clockwise and counterclockwise. In this embodiment, the swing piece 310 is arranged to drive the spray head 200 to move by rotating, and the rotating force of the swing piece 310 can be converted into the force driving the spray head 200 to translate in the first direction X, so as to realize the position adjustment of the spray head 200 in the first direction X by the first adjusting assembly 300. In addition, the swing piece 310 is connected with the connecting part 221 of the spray head 200 for mounting, so that the connection of the swing piece 310 with the spray head does not occupy the space outside the spray head 200.

[0037] Specifically, the clockwise rotation of the swing piece 310 can push the connecting part 221 to make the spray head 200 slide along the positive direction of the first direction X, and the counterclockwise rotation of the swing piece 310 can push the connecting part 221 to make the spray head 200 slide along the reverse direction of the first direction X.

[0038] It should be noted that the clockwise direction and the counterclockwise direction herein are for facilitating description of the rotation of the swing member 310 in two opposite directions, and only two opposite rotation directions are defined herein, and are not necessarily clockwise or counterclockwise. Similarly, the positive direction of the first direction X and the negative direction of the first direction X are for facilitating description of the two opposite adjustment positions of the nozzle 200 along the first direction X, and only two opposite movement directions are defined herein, and are not necessarily positive or negative. In addition, it should be noted that in the present application, the positive direction of the first direction X and the negative direction of the first direction X are only needed to distinguish the position adjustment direction of the nozzle 200, and when it is not needed to distinguish, the first direction X can be directly referred to as the first direction X.

[0039] In the embodiment of the present application, through cooperation of the swing member 310 and the connecting portion 221, the connecting portion 221 can be pushed to slide along the positive direction or the negative direction of the first direction X by rotating the swing member 310, so as to realize position adjustment of the nozzle 200 along the first direction X, and two swing members 310 do not need to be respectively arranged at the opposite ends of the nozzle 200 to respectively push the nozzle 200 to slide along the positive direction and the negative direction of the first direction X, thereby reducing the occupied space of the first adjustment assembly 300 between adjacent nozzles 200, so that even if a plurality of nozzles 200 are arranged along the first direction X, the first interval of adjacent ejection orifices between adjacent nozzles 200 can be the same as the second interval of adjacent ejection orifices in the nozzle 200, thereby ensuring the printing quality of the printing die 1. It can be understood that in other embodiments of the present application, the swing member 310 can also be arranged at the opposite ends of the nozzle 200 along the first direction X, and the nozzle 200 can be pushed to slide along the positive direction or the negative direction of the first direction X by the two swing members 310 respectively, so as to realize position adjustment of the nozzle 200 along the first direction X.

[0040] In some embodiments, referring to 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, and the swing member 310 can push the connecting portion 221 by the two pushing arms 3111 respectively when the swing member 310 rotates clockwise and counterclockwise, so as 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 portion 221 to move the nozzle 200 along the positive direction of the first direction X; and when the swing member 310 rotates counterclockwise, the other pushing arm 3111 can push the connecting portion 221 to move the nozzle 200 along the negative direction of the first direction X.

[0042] In the embodiment, the two push arms 3111 are arranged between the connecting part 221, so that the two push arms 3111 can push the connecting part 221 to move in different directions respectively, without the need to arrange two swing members 310 to push the connecting part 221 respectively. It can be understood that in other embodiments of the present application, the two swing members 310 can also be arranged to push the connecting part 221 respectively.

[0043] In some embodiments, the two push arms 3111 are arranged in a relative and spaced manner along the first direction X, i.e. arranged flush. It can be understood that in other embodiments of the present application, the two push arms 3111 can also be distributed along the first direction X and arranged in a vertically staggered manner.

[0044] In some embodiments, the inkjet module 1 further comprises a first locking member (not shown in the figure), which is used to lock the connecting part 221 to the mounting plate 100. When it is necessary to adjust the position of the nozzle 200, the first locking member can be loosened, so that the swing member 310 can be driven to rotate to push the connecting part 221, thereby achieving adjustment of the position of the nozzle 200; after the position of the nozzle 200 is adjusted, the connecting part 221 is locked to the mounting plate 100 by the first locking member, so as to ensure the safety of the nozzle 200 in use.

[0045] Specifically, please refer to Figure 4 , the mounting plate 100 has a first mounting hole 110, the connecting part 221 has a second mounting hole 2211, and the first locking member penetrates the second mounting hole 2211 and the first mounting hole 110 in sequence to lock the connecting part 221 to the mounting plate 100. Specifically, in order to achieve adjustment of the position of the connecting part 221 on the mounting plate 100, the first mounting hole 110 is arranged to have a gap with the first locking member along the first direction X, and the second mounting hole 2211 is arranged to be matched with the first locking member, so that after the position of the mounting part 421 is adjusted, the first locking member can still be inserted into the first mounting hole 110 to lock the connecting part 221.

[0046] In some embodiments, the first adjusting assembly 300 further comprises a driving member movably arranged on the mounting plate 100, by which the swing member 310 can be pushed to rotate clockwise and counterclockwise. The arrangement of the driving member facilitates the rotation of the swing member 310 and reduces the operation difficulty of rotating the swing member 310. It can be understood that in other embodiments of the present application, the driving member can also not be arranged, and the swing member 310 can be directly manually pushed to rotate clockwise or counterclockwise.

[0047] In some embodiments, please refer to Figure 3 and Figure 4The driving member includes a first eccentric member 320, and the first eccentric member 320 is rotationally arranged on the mounting plate 100. The swinging member 310 includes two matching arms 3121, and the driving of the first eccentric member 320 can respectively push the two matching arms 3121 to make the swinging member 310 rotate clockwise and counterclockwise. Through the arrangement of the first eccentric member 320, the forward and reverse eccentric rotation of the first eccentric member 320 can respectively drive the two matching arms 3121, without the need to arrange two driving members to respectively drive the two matching arms 3121, and the driving is simple. In addition, the rotation of the first eccentric member 320 can also be realized through a special tool, which reduces the rotation difficulty of the first eccentric member 320.

[0048] Specifically, please refer to Figure 3 The two matching arms 3121 are arranged in a relative and spaced manner along the first direction X, the first eccentric member 320 is rotationally arranged between the two matching arms 3121, and the first eccentric member 320 can respectively push the two matching arms 3121 when rotating forward and reversely, thereby driving the swinging member 310 to rotate clockwise or counterclockwise.

[0049] Specifically, please refer to Figure 3 The first eccentric member 320 is provided with a matching port 321, when it is necessary to rotate the first eccentric member 320, a special tool can be inserted into the matching port 321 to drive the first eccentric member 320 to rotate, thereby reducing the operation difficulty. At the same time, the occupied space of the first eccentric member 320 can also be reduced.

[0050] In some embodiments, the first adjusting assembly 300 further includes a second locking member for locking the adjusted first eccentric member 320 to the mounting plate 100. Specifically, please refer to Figure 4 The mounting plate 100 is provided with a third mounting hole 120, the first eccentric member 320 is provided with an axially penetrating fourth mounting hole 322, and the second locking member respectively penetrates through the third mounting hole 120 and the fourth mounting hole 322 to lock the first eccentric member 320 to the mounting plate 100.

[0051] Specifically, the first eccentric member 320 includes a first rotating part 323 and a first eccentric part 324 connected in an axial direction, the first rotating part 323 is in a cylindrical shape, and the first eccentric part 324 is an eccentric structure arranged eccentrically relative to the central axis of the first rotating part 323. The mounting plate 100 is provided with a first matching hole 130, and the first rotating part 323 rotationally matches 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, please refer to Figure 3The swing member 310 comprises 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, and 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 connecting 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 have a larger size, and the first eccentric member 320 can rotate a smaller angle to meet the position adjustment of the connecting portion 221 along the second direction X, thereby improving the adjustment efficiency of the nozzle 200 along the second direction X.

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

[0054] Optionally, please refer to Figure 3 and Figure 4 The swing member 310 has a rotating hole 313 formed at the connection between the first swing portion 311 and the second swing portion 312. The mounting plate 100 is provided with a fixing member 330, and the rotating hole 313 is sleeved on the fixing member 330, thereby forming the swing of the swing member 310 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, please refer to Figure 2 and Figure 3The nozzle 200 comprises a nozzle body 210 and ink receiving portions 220 arranged at opposite ends of the nozzle body 210 along the first direction X, and the two ink receiving portions 220 are arranged staggered along the second direction Y. When two adjacent nozzles 200 are arranged spaced apart along the first direction X, the first swing portion 311 is inserted between the nozzle body 210 of one of the nozzles 200 and the ink receiving portion 220 of the other nozzle 200. In this nozzle structure, when the nozzles are spliced in a width expansion manner, the ink receiving portion 220 substantially occupies most of the space between the adjacent nozzles 200 along the second direction Y. The design scheme of the first adjusting assembly 300 of the embodiment is applied in this nozzle splicing, and the applicability in the structure scenario with extremely limited space is more significant.

[0057] In some embodiments, referring to Figure 2 and Figure 5 The second adjusting assembly 400 comprises a second eccentric member 410 and an elastic member 420, the second eccentric member 410 and the elastic member 420 are respectively arranged at opposite sides of the nozzle 200 along the second direction Y, and the second eccentric member 410 is rotationally arranged on the mounting plate 100. Specifically, when the second eccentric member 410 rotates clockwise or counterclockwise, the second eccentric member 410 can push the nozzle 200 to move along the second direction Y. When the second eccentric member 410 rotates clockwise, the nozzle 200 can move along the second direction Y towards the elastic member 420, compressing the elastic member 420, and the elastic member 420 accumulates elastic force; when the second eccentric member 410 rotates counterclockwise, the nozzle 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 nozzle 200 along the second direction Y. In this embodiment, the second eccentric member 410 and the elastic member 420 can be arranged between two adjacent nozzles 200 along the second direction Y.
