Description

Technical Field

[0001] This invention relates to the field of inkjet printing technology, and in particular to a printhead module and inkjet printing equipment. Background Technology

[0002] With the development of the times, the progress of technology, and the urgent need for energy conservation and emission reduction, digital inkjet printing equipment has emerged to replace traditional printing equipment. The printhead module of digital inkjet printing equipment includes multiple printhead structures mounted on a mounting frame and distributed in an array. Each printhead structure can spray ink independently. By controlling the operation of the corresponding printhead structure, the digital inkjet printing equipment can print the corresponding pattern. However, after the printhead structure is mounted on the mounting frame, the position of the printhead structure needs to be adjusted in some cases.

[0003] In related technologies, when installing the nozzle structure and the mounting bracket, the nozzle structure is pressed onto the mounting bracket by a limiting block, and the nozzle structure is moved along the mounting surface of the mounting bracket by adjusting bolts on the limiting block, so as to adjust the position of the nozzle structure.

[0004] Correspondingly, when disassembling and assembling the nozzle structure, workers need to disassemble and assemble the limit blocks and adjusting bolts accordingly, making the disassembly and assembly process of the nozzle structure quite cumbersome. Summary of the Invention

[0034] The following is for reference. Figures 1 to 8 The nozzle module of the first aspect of this application will be described in detail.

[0035] refer to Figure 1 , Figure 2 and Figure 5According to a first aspect embodiment of the present invention, a nozzle module includes a mounting frame 100 and a nozzle structure 200; the mounting frame 100 has a mounting surface 110 and a first abutment structure is provided on the mounting frame 100; the nozzle structure 200 includes a nozzle 210, a first adjusting member 220, a first elastic member 230, and a floating connector 240, the nozzle 210 is disposed on the mounting surface 110, the floating connector 240 is detachably connected to the mounting frame 100 and is floatingly connected to the nozzle 210, the floating direction of the nozzle 210 being perpendicular to the mounting surface 110. The mounting surface 110 is parallel to each other. The first adjusting member 220 is movably disposed on the nozzle 210 and abuts against the first abutting structure through the first inclined structure. Under the action of external force, the first adjusting member 220 can move relative to the first abutting structure to push the nozzle 210 to move in a first direction parallel to the mounting surface 110. The first elastic member 230 is disposed on the nozzle 210 and abuts against the mounting bracket 100. The first elastic member 230 is used to provide elastic force to keep the first adjusting member 220 abutting against the first abutting structure.

[0036] For example, such as Figure 1 , Figure 2 and Figure 5 As shown, the nozzle module includes a mounting bracket 100 and a nozzle structure 200. The mounting bracket 100 has a horizontally extending mounting surface 110 and a first abutting structure. The mounting surface 110 has a first abutting structure on its right side. The nozzle structure 200 includes a nozzle 210, a first adjusting member 220, a first elastic member 230, and a floating connector 240. The nozzle 210 is disposed on the mounting surface 110. The first adjusting member 220 is movably mounted on the right end of the nozzle 210, and the first adjusting member 220 is connected to the first abutting structure via a first inclined surface structure. The first elastic member 230 is located at the left end of the nozzle 210 and abuts against the mounting bracket 100. The first elastic member 230 is used to provide a spring force to keep the nozzle 210 to the right so that the first adjusting member 220 remains in contact with the first abutting structure. Two floating connectors 240 are provided, which are respectively located at the left and right ends of the nozzle 210. The floating connectors 240 are floatingly connected to the nozzle 210 and detachably connected to the mounting bracket 100, so that the nozzle 210 can float relative to the mounting bracket 100 in the left and right directions.

[0037] It is understood that when connecting the nozzle structure 200 and the mounting bracket 100, the operator can connect the floating connector 240 to the mounting bracket 100, thereby achieving the connection between the nozzle structure 200 and the mounting bracket 100. At this time, the first adjusting member 220 on the nozzle 210 abuts against the first abutting structure on the mounting bracket 100, and the first elastic member 230 on the nozzle 210 abuts against the mounting bracket 100. By driving the first adjusting member 220 to move, the operator can cause the first adjusting member 220 to move the nozzle 210 along the first direction, thereby achieving position adjustment of the nozzle 210 in the first direction. Correspondingly, when disassembling the nozzle structure 200 from the mounting bracket 100, the operator can release the connection between the floating connector 240 and the mounting bracket 100, thereby achieving separation between the nozzle structure 200 and the mounting bracket 100. In the nozzle module, by floating the floating connector 240 to the nozzle 210, and by placing the first adjusting member 220 and the first elastic member 230 on the nozzle 210, on the one hand, the operator can install or remove the nozzle structure 200 on the mounting frame 100 by connecting or removing the floating connector 240 from the mounting frame 100, making the installation and removal of the nozzle structure 200 more convenient. On the other hand, after the floating connector 240 is connected to the mounting frame 100, the operator can quickly adjust the position of the nozzle 210 in the first direction by using the first adjusting member 220. Furthermore, since the floating connector 240, the first adjusting member 220, and the first elastic member 230 are all placed on the nozzle 210, there are no other extra structures affecting the installation area of ​​the nozzle structure 200 on the mounting frame 100, which facilitates the installation of the nozzle structure 200 on the mounting frame 100.

[0038] In some embodiments of the present invention, the first abutting structure is a V-groove 120 provided on the mounting bracket 100, and the first adjusting member 220 is provided with a first inclined surface structure.

[0039] For example, such as Figure 2 and Figure 3 As shown, the first abutting structure is a V-shaped groove 120 provided on the mounting bracket 100, with the opening of the V-shaped groove 120 facing left. The first inclined structure is provided on the first adjusting member 220, which is movably arranged relative to the nozzle 210 in the vertical direction. The first inclined structure abuts against the two side walls of the V-shaped groove 120 respectively.

[0040] It is understandable that by setting the V-groove 120, under the limiting effect of the two sidewalls of the V-groove 120, when the operator drives the first adjusting member 220 to move in the vertical direction, the two sidewalls of the V-groove 120 can push the first adjusting member 220 to move in the left and right direction in the opposite direction, thereby realizing the position adjustment of the nozzle 210 in the left and right direction; the setting of the V-groove 120 can reduce the offset of the nozzle 210 in the front and back direction under the adjustment of the first adjusting member 220, so that the position adjustment of the nozzle 210 in the first direction under the adjustment of the first adjusting member 220 is more precise.

[0041] In a further embodiment of the present invention, the first adjusting member 220 is threadedly connected to the nozzle 210, and the first inclined surface structure is a first conical surface 220a provided on the circumferential surface of the first adjusting member 220.

[0042] For example, such as Figure 6 As shown, the first adjusting member 220 extends vertically, and the nozzle 210 is provided with a vertically extending threaded hole. The first adjusting member 220 passes through the threaded hole and is threadedly connected to the hole wall. The lower end of the first adjusting member 220 is provided with a first conical surface 220a, which forms a first inclined surface structure. The first conical surface 220a abuts against the groove sidewall of the V-groove 120.

[0043] Furthermore, by rotating the first adjusting member 220, the operator can move the first adjusting member 220 in the vertical direction. During the vertical movement of the first adjusting member 220, under the guidance of the first conical surface 220a, the sidewall of the V-groove 120 can push the first adjusting member 220 to drive the nozzle 210 to move left and right.

[0044] It is understandable that by threading the first adjusting member 220 to the nozzle 210, the displacement of the first adjusting member 220 in the vertical direction can be made more accurate, thereby improving the position adjustment accuracy of the nozzle 210 in the first direction.

[0045] It is understandable that the first conical surface 220a is designed so that during the rotation of the first adjusting member 220, the first conical surface 220a can always abut against the two sidewalls of the V-groove 120, thereby ensuring that the adjustment of the nozzle 210 position in the first direction by the first adjusting member 220 can be achieved smoothly.

[0046] Understandably, during the downward rotation of the first adjusting member 220, under the compression of the first conical surface 220a, the first elastic member 230 will compress to the left. With the assistance of the elastic force of the first elastic member 230, the nozzle 210 is adjusted to the left. The first elastic member 230 ensures that the first adjusting member 220 and the two groove walls of the V-groove 120 are always in a state of mutual compression, thereby reducing the probability of the nozzle 210 being displaced in the left and right directions. During the upward rotation of the first adjusting member 220, under the elastic force of the first elastic member 230, the nozzle 210 moves to the right, thereby adjusting the position of the nozzle 210 to the right, and ensuring that the first conical surface 220a is always in a state of mutual compression with the two groove walls of the V-groove 120, thereby reducing the probability of the nozzle 210 being displaced in the left and right directions.

[0047] Understandably, in traditional nozzle modules, an adjustment screw is typically provided on each of the left and right sides of the mounting bracket 100. By turning the two adjustment screws, the nozzle 210 on the mounting bracket 100 is moved in the left and right direction. However, this adjustment method requires two adjustment screws to work together to push the nozzle 210 in the left and right direction. For example, when it is necessary to adjust the nozzle 210 to move to the right, the right adjustment screw needs to be turned to avoid the nozzle 210, and the left adjustment screw needs to be turned to push the nozzle 210 to move to the right. The adjustment accuracy of the nozzle 210 is relatively low. In this application, by setting a first elastic element 230, after the first adjustment element 220 moves upward, the nozzle 210 can adaptively move to the right under the elastic force of the first elastic element 230, so that the first adjustment element 220 remains in contact with the V-groove 120. The operator does not need to manually move the nozzle 210, and the adjustment accuracy of the nozzle 210 is higher.

[0048] In a further embodiment of the invention, reference is made to... Figure 6 The first adjusting member 220 includes a handle portion 221 and an abutment portion 222. The abutment portion 222 includes a conical abutment section 222a and a cylindrical positioning section 222b. The upper end of the handle portion 221 is detachably connected to the positioning section 222b, and the lower end of the abutment section 222a is connected to the positioning section 222b. The first conical surface 220a is the circumferential surface of the abutment section 222a, and the circumferential surface of the positioning section 222b is in arc-shaped fit with the nozzle 211.

[0049] Understandably, because the circumferential surface of the positioning section 222b matches the arc of the nozzle 211, the horizontal sway of the entire contact section 222 is smaller when the contact section 222a is subjected to a horizontal load from the groove wall of the V-groove 120, thereby ensuring the installation accuracy of the entire first adjusting member 220 and improving the adjustment accuracy of the first adjusting member 220 on the nozzle 210.

[0050] In some embodiments of the present invention, the bisector of the V-groove 120 extends along a first direction.

[0051] It is understandable that by extending the bisector of the V-groove 120 along the first direction, the first adjusting member 220, when moving relative to the V-groove 120, can drive the nozzle 210 to move stably along the first direction under the guidance of the first inclined structure and the two sidewalls of the V-groove 120, so as to achieve accurate adjustment of the position of the nozzle 210 in the first direction.

[0052] In some embodiments of the present invention, reference is made to Figure 7 The first elastic member 230 includes a connecting part 231 and a deformable part 232 connected to each other. The connecting part 231 is detachably connected to the nozzle 210, and the end of the deformable part 232 facing away from the connecting part 231 abuts against the mounting bracket 100.

[0053] Understandably, under the elastic force of the deformable part 232 itself, the first elastic member 230 can push the nozzle 210 closer to the first abutting structure, so that the first inclined structure of the first adjusting member 220 and the first abutting structure always remain in contact.

[0054] It is understandable that since the connecting part 231 is detachably connected to the nozzle 210, it is convenient for the staff to disassemble and assemble the first elastic element 230, so that the staff can install the first elastic element 230 of the corresponding specification on the nozzle 210 according to the needs.

[0055] In some embodiments of the present invention, the deformable part 232 is U-shaped.

[0056] It is understandable that by setting the deformation part 232 to a U-shape, it is convenient to install the deformation part 232 between the nozzle 210 and the mounting bracket 100, and it is also convenient for the deformation part 232 to deform so as to better provide elastic force to the nozzle 210.

[0057] Understandably, the U-shaped deformation part 232 makes it easier to install the nozzle structure 200 on the mounting bracket 100. When installing the nozzle structure 200 on the mounting bracket 100, the operator does not need to apply excessive pressure to the nozzle structure 200 to install it on the mounting surface 110 of the mounting bracket 100, and the end of the deformation part 232 away from the nozzle 210 abuts against the mounting bracket 100. Since the force applied by the operator to the nozzle structure 200 during installation is smaller, the impact force generated between the nozzle 210 and the mounting surface 110 can be reduced, thereby reducing the impact damage of the mounting surface 110 to the nozzle 210.

[0058] In some embodiments of the present invention, the nozzle structure 200 further includes a second adjusting member 250 and a second elastic member 260. The mounting bracket 100 is provided with a second abutting structure. The second adjusting member 250 is movable on the nozzle 210 and abuts against the second abutting structure through a second inclined structure. Under the action of external force, the second adjusting member 250 can move relative to the second abutting structure to push the nozzle 210 to move along a second direction parallel to the mounting surface 110. The second direction is set at a certain angle from the first direction. The second elastic member 260 is provided on the nozzle 210 and abuts against the mounting bracket 100. The second elastic member 260 is used to provide elastic force to keep the second adjusting member 250 abutting against the second abutting structure.

[0059] For example, such as Figure 5 As shown, the second direction is the front-to-back direction. The nozzle structure 200 also includes a second adjusting member 250 and a second elastic member 260. The second adjusting member 250 is located at the left rear end of the nozzle 210, and the second elastic member 260 is located at the left front end of the nozzle 210. A second abutting structure is provided on the rear side of the mounting surface 110. The second adjusting member 250 abuts against the second abutting structure through the second inclined surface structure. Thus, under the elastic force of the second elastic member 260, the nozzle 210 pushes the second adjusting member 250 backward so that the second adjusting member 250 remains in contact with the second abutting structure.

[0060] Understandably, the operator adjusts the second adjusting member 250 so that the second adjusting member 250 moves relative to the second abutting structure, thereby causing the second abutting structure to push the second adjusting member 250 to move in the front-back direction, and thus the second adjusting member 250 drives the nozzle 210 to move in the front-back direction, so as to achieve the position adjustment of the nozzle 210 in the front-back direction.

[0061] In some embodiments of the present invention, the second abutting structure is an abutting surface 130 provided on the mounting bracket 100, the abutting surface 130 is arranged perpendicular to the second direction, and the second adjusting member 250 is provided with a second inclined surface structure.

[0062] For example, such as Figure 4 As shown, the second direction is the front-to-back direction, the contact surface 130 is a vertical surface perpendicular to the front-to-back axis, the second adjusting member 250 is movably mounted on the nozzle 210 in the vertical direction, and the second inclined structure is located at the lower end of the second adjusting member 250.

[0063] Understandably, by driving the second adjusting member 250 to move vertically, the contact surface 130 can push the second adjusting member 250 to move the nozzle 210 forward under the action of the second inclined structure, so as to achieve the position adjustment of the nozzle 210 in the front-back direction.

[0064] In a further embodiment of the present invention, the second adjusting member 250 extends in the vertical direction, penetrates the nozzle 210 in the vertical direction, and is threadedly connected to the nozzle 210. The lower end of the second adjusting member 250 is provided with a second conical surface 251, which forms a second inclined surface structure. The second conical surface 251 abuts against the contact surface 130.

[0065] Furthermore, by rotating the second adjusting member 250, the operator can move the second adjusting member 250 in the vertical direction. During the vertical movement of the second adjusting member 250, under the guidance of the second conical surface 251, the abutment surface 130 can push the second adjusting member 250 to drive the nozzle 210 to move back and forth.

[0066] It is understandable that by threading the second adjusting member 250 to the nozzle 210, the displacement of the second adjusting member 250 in the vertical direction can be made more accurate, thereby improving the position adjustment accuracy of the nozzle 210 in the second direction.

[0067] It is understandable that the second conical surface 251 is designed so that the second adjusting member 250 can always abut against the contact surface 130 during the rotation process, thereby ensuring that the second adjusting member 250 can smoothly adjust the position of the nozzle 210 in the second direction.

[0068] Understandably, during the downward rotation of the second adjusting member 250, the second elastic member 260 will compress forward under the pressure of the second conical surface 251. With the assistance of the elastic force of the second elastic member 260, the nozzle 210 is adjusted forward. The second elastic member 260 ensures that the second adjusting member 250 and the contact surface 130 are always pressed together, thereby reducing the probability of the nozzle 210 being displaced in the front-back direction. During the upward rotation of the second adjusting member 250, the nozzle 210 moves backward under the elastic force of the second elastic member 260, thereby adjusting the position of the nozzle 210 backward and ensuring that the second conical surface 251 is always pressed together with the contact surface 130, thereby reducing the probability of the nozzle 210 being displaced in the front-back direction.

[0069] It should be noted that since the first abutment structure is a V-groove 120, when the operator adjusts the left end of the nozzle 210 to move it back and forth through the second adjusting member 250, the nozzle 210 rotates around the first adjusting member 220, thereby realizing the rotation adjustment of the nozzle 210.

[0070] In some embodiments of the present invention, reference is made to Figure 8The nozzle 210 is provided with a limiting hole 211. The floating connector 240 passes through the limiting hole 211 and is threadedly connected to the mounting bracket 100. A floating gap is left between the floating connector 240 and the hole wall of the limiting hole 211.

[0071] It is understandable that after the floating connector 240 is threadedly connected to the mounting bracket 100, the floating gap between the wall of the limiting hole 211 and the floating connector 240 allows the nozzle 210 to float horizontally relative to the floating connector 240. The floating connector 240 enables both the nozzle 210 to float along the mounting surface 110 and the nozzle 210 to be installed on the mounting surface 110.

[0072] In a further embodiment of the invention, reference is made to... Figure 8 The floating connector 240 includes a limiting section 241, an inserting section 242, and a connecting section 243. The upper and lower ends of the inserting section 242 are connected to the limiting section 241 and the connecting section 243, respectively. The connecting section 243 has threads on its circumferential surface and is threaded to the mounting bracket 100. The inserting section 242 passes through the limiting hole 211 and has a floating gap between it and the hole wall of the limiting hole 211.
