Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of printing equipment, and more particularly to a nozzle bottom plate adjusting device. BACKGROUND

[0002] An inkjet printer is a printing device that forms a desired image or text by ejecting ink droplets from a printing nozzle to a corresponding position on a printing medium. Depending on the printing needs, some inkjet printers are equipped with multiple printing nozzles, which are installed on a nozzle bottom plate. Due to the heavy total mass of the printing nozzles and the large size of the nozzle bottom plate, the position of the nozzle bottom plate may be skewed due to assembly process, machining error, or self-weight, and thus the position of the nozzle bottom plate needs to be adjusted to ensure the accuracy of the landing position of the printing nozzle ejection point.

[0003] The adjusting mechanism for adjusting the position of the nozzle bottom plate in the prior art has a complex structure and a large number of adapter plates, which occupies a large space in the width direction of the frame, thereby reducing the installation position of the nozzle bottom plate in the width direction of the frame, resulting in a small number of single-row printing nozzles installed on the nozzle bottom plate in the width direction of the frame, and a small printing width. If the number of single-row printing nozzles needs to be increased to increase the printing width, the nozzle bottom plate needs to be widened, and the size of the frame also needs to be increased. If the size of the frame is increased, the frame needs to be disassembled before being loaded into the centralized box, which makes the frame loading work difficult and increases the transportation cost.

[0031] The frame 100 is connected with a lead screw assembly. Specifically, the frame 100 is threadedly sleeved on the lead screw through a nut sleeve, and then the lead screw is driven to rotate by a motor, thereby driving the frame 100 to move. The frame 100 is made of high-strength aluminum alloy and is precisely machined and assembled, so it is light in weight, high in precision and stable in structure.

[0032] The nozzle base plate 200 is used for mounting the printing nozzle of the printing device and part of the components of the adjusting mechanism 300.

[0033] The adjusting mechanism 300 is used for adjusting the position of the nozzle base plate 200.

[0034] The nozzle bottom plate adjusting device provided by the application, compared with the prior art, by connecting the first support plate 10 with one end of the nozzle bottom plate 200, and slidingly fitting the bottom surface of the frame 100 along the width direction F1 of the frame 100, when the first adjusting assembly 50 adjusts the first support plate 10 to move along the width direction F1 of the frame 100, the first support plate 10 drives the nozzle bottom plate 200 to move synchronously, so as to realize the adjustment of the position of the nozzle bottom plate 200 in the width direction F1 of the frame 100, by locating a part of the first support plate 10 inside the frame 100 and extending the other part to the bottom surface position of one end of the frame 100, the occupation of the internal space of the frame 100 by the first support plate 10 in the width direction F1 of the frame 100 is effectively reduced, and by slidingly fitting the first support plate 10 with the bottom surface of the frame 100 along the width direction F1 of the frame 100, various intermediate adapter plates between the bottom plate and the frame 100 are omitted, which is conducive to simplifying the structure of the adjusting mechanism 300, thereby effectively reducing the occupation of the internal space of the frame 100 by the adjusting mechanism 300 in the width direction F1 of the frame 100, so as to effectively increase the installation position of the nozzle bottom plate 200 in the width direction of the frame 100, so that more printing nozzles can be installed in a single row of the nozzle bottom plate 200 in the width direction F1 of the frame 100, so as to increase the printing width without increasing the size of the frame 100, so that the frame 100 can be smoothly loaded into the centralized box without being disassembled, which is conducive to reducing transportation costs.

[0035] Specifically, the conventional adjusting mechanism includes a first adapter block, a second adapter block, a third adapter block and a fourth adapter block, the first adapter block, the second adapter block, the third adapter block and the fourth adapter block are located in the frame 100, the first adapter block is connected with the nozzle bottom plate, the second adapter plate is connected with the inner side wall of the frame 100, the third adapter block is slidably arranged on the second adapter block along the width direction of the frame 100, the fourth adapter block is slidably arranged on the third adapter block along the length direction of the frame 100 and is connected with the first adapter block, the installation steps are more, the number of adapter blocks is more, the space occupied by the adapter blocks in the width direction of the frame 100 is larger, in the case that the nozzle bottom plate is not lengthened along the width direction of the frame 100, five nozzles can be installed in a single row of the nozzle bottom plate in the width direction of the frame 100, the printing width cannot exceed 330 mm, that is, the printing width on the printing medium cannot exceed 330 mm, and the width of the frame 100 has reached 2.1 meters, if the nozzle bottom plate needs to be lengthened along the width direction of the frame 100, the frame 100 also needs to be widened synchronously, if the frame 100 is widened, it cannot be smoothly transferred into the centralized box without disassembly. The nozzle bottom plate adjusting device of the present application reduces the space occupied by the adjusting mechanism 300 in the width direction of the frame 100 inside to increase the installation position of the nozzle bottom plate 200 in the width direction of the frame 100 inside while the width of the frame 100 remains unchanged, specifically, the adjusting mechanism 300 occupies a width of about 5 centimeters on both ends of the frame 100 in the width direction F1 of the frame 100, the space occupied by the adjusting mechanism 300 in the frame 100 is small, the nozzle bottom plate 200 can be lengthened along the width direction F1 of the frame 100, seven nozzles can be installed in a single row of the nozzle bottom plate 200 along the width direction F1 of the frame 100, and the printing width can reach 440 mm, that is, the maximum printing width on the printing medium can reach 440 mm, since the frame 100 does not need to be widened, it can be smoothly loaded into the centralized box without disassembly, which is beneficial to reduce transportation cost.

[0036] In some embodiments of the present application, please refer to Figure 2 The adjusting mechanism 300 further includes a first connecting block 20, the first connecting block 20 is located in the frame 100 and is arranged close to the first support plate 10, the first connecting block 20 is L-shaped, the first connecting block 20 is connected with the inner side wall of the frame 100 close to one end of the first support plate 10 and is slidably matched with the part of the first support plate 10 located in the frame 100 along the width direction F1 of the frame 100. By connecting the first connecting block 20 with the inner side wall of the frame 100 and slidably matching the part of the first support plate 10 located in the frame 100 along the width direction F1 of the frame 100, the stability of the first support plate 10 when moving along the width direction F1 of the frame 100 is improved.

[0037] Further, the first connecting block 20 is provided in plurality, and the plurality of first connecting blocks 20 are arranged along the length direction F2 of the frame 100. By arranging the plurality of first connecting blocks 20 to slide along the width direction F1 of the frame 100 with the first support plate 10, the stability of the first support plate 10 when moving along the width direction F1 of the frame 100 is improved. Optionally, the number of first connecting blocks 20 is two, and the two first connecting blocks 20 are arranged at opposite ends of the first support plate 10 along the length direction F2 of the frame 100.

[0038] In some embodiments of the present application, a first guide hole 21 is formed between the frame 100, the first connecting block 20 and the first support plate 10, and the axial direction of the first guide hole 21 is along the width direction F1 of the frame 100. The adjusting mechanism 300 further comprises a first guide shaft 22, and the axial direction of the first guide shaft 22 is along the width direction F1 of the frame 100. The first guide shaft 22 is arranged in the first guide hole 21 along the width direction F1 of the frame 100 and is matched with the first guide hole 21. By matching the first guide shaft 22 with the first guide hole 21, the offset in the length direction F2 of the frame 100 when the first support plate 10 moves along the width direction F1 of the frame 100 is effectively prevented, thereby effectively improving the stability of the first support plate 10 when moving the showerhead bottom plate 200 along the width direction F1 of the frame 100, i.e. effectively improving the adjustment accuracy of the position of the showerhead bottom plate 200 along the width direction F1 of the frame 100.

[0039] Please refer to Figure 2 and Figure 3 , wherein the first guide shaft 22 is fixedly connected with the first support plate 10, such as screw connection or interference fit. The first guide shaft 22 is provided with a first fixing hole 221, and the first connecting block 20 is provided with a first adjusting hole 4323 extending along the width direction F1 of the frame 100. The first adjusting hole 4323 is arranged corresponding to the first fixing hole 221, and a screw or a bolt is arranged to pass through the first adjusting hole 4323 and insert into the first fixing hole 221 to connect the first connecting block 20 with the first guide shaft 22. It can be understood that, since the length of the first adjusting hole 4323 extends along the width direction F1 of the frame 100, the first adjusting hole 4323 is always in communication with the first fixing hole 221 during the adjustment of the first support plate 10 along the width direction F1 of the frame 100. Therefore, when the position of the showerhead bottom plate 200 along the width direction F1 of the frame 100 is adjusted, the screw or the bolt is arranged to pass through the first adjusting hole 4323 from the position corresponding to the first fixing hole 221 and insert into the first fixing hole 221 to connect the first connecting block 20 with the first guide shaft 22.

[0040] In some embodiments of the present application, the adjusting mechanism 300 further comprises a second support plate 30, which is arranged opposite to the first support plate 10 along the frame 100 width direction F1, and is connected to the other end of the shower nozzle bottom plate 200. A part of the second support plate 30 is located inside the frame 100, and the other part extends to the bottom surface position of the other end of the frame 100 and is in sliding fit with the bottom surface of the frame 100 along the frame 100 width direction F1. By matching the second support plate 30 with the first support plate 10, the stability of the movement of the shower nozzle bottom plate 200 along the frame 100 width direction F1 is improved. In addition, by locating a part of the second support plate 30 inside the frame 100 and extending the other part to the bottom surface position of the other end of the frame 100, the occupation of the second support plate 30 in the internal space of the frame 100 in the frame 100 width direction F1 is effectively reduced. By sliding fit of the second support plate 30 with the bottom surface of the frame 100 along the frame 100 width direction F1, various intermediate adapter plates between the bottom plate and the frame 100 are omitted, which is conducive to simplifying the structure of the adjusting mechanism 300. Therefore, the occupation of the adjusting mechanism 300 in the internal space of the frame 100 in the frame 100 width direction F1 is effectively reduced, thereby effectively increasing the installation position of the shower nozzle bottom plate 200 in the internal width direction of the frame 100.

[0041] In some embodiments of the present application, the adjusting mechanism 300 further comprises a second connecting block 40, which is located inside the frame 100 and arranged close to the second support plate 30. The second connecting block 40 is L-shaped, and is connected to the inner side wall of the frame 100 close to one end of the second support plate 30 and is in sliding fit with the part of the second support plate 30 inside the frame 100 along the frame 100 width direction F1. By connecting the second connecting block 40 to the inner side wall of the frame 100 and sliding fit with the part of the second support plate 30 inside the frame 100 along the frame 100 width direction F1, the stability of the movement of the second support plate 30 along the frame 100 width direction F1 is improved.

[0042] Further, the number of second connecting blocks 40 is multiple, and the multiple second connecting blocks 40 are arranged at intervals along the frame 100 length direction F2. By arranging multiple second connecting blocks 40 to simultaneously slide with the second support plate 30 along the frame 100 width direction F1, the stability of the movement of the second support plate 30 along the frame 100 width direction F1 is improved. Optionally, the number of second connecting blocks 40 is two, and the two second connecting blocks 40 are respectively arranged at opposite ends of the second support plate 30 along the frame 100 length direction F2.

[0043] In some embodiments of the present application, a second guide hole 41 is formed between the frame 100, the second connecting block 40 and the second support plate 30, the axial direction of the second guide hole 41 is along the width direction F1 of the frame 100, and the adjusting mechanism 300 further comprises a second guide shaft 42, the axial direction of the second guide shaft 42 is along the width direction F1 of the frame 100, the second guide shaft 42 is arranged in the second guide hole 41 along the width direction F1 of the frame 100 and is matched with the second guide hole 41. By matching the second guide shaft 42 with the second guide hole 41, the offset in the length direction F2 of the frame 100 when the second support plate 30 moves along the width direction F1 of the frame 100 is effectively prevented, thereby effectively improving the stability of the second support plate 30 driving the shower head bottom plate 200 to move along the width direction F1 of the frame 100, that is, effectively improving the adjustment accuracy of the position of the shower head bottom plate 200 in the width direction F1 of the frame 100.

[0044] The second guide shaft 42 is fixedly connected with the second support plate 30, for example, the second guide shaft 42 is screw-connected or interference-fitted with the second support plate 30. The second guide shaft 42 is provided with a second fixing hole 421, and the second connecting block 40 is provided with a second adjusting hole extending along the width direction F1 of the frame 100. The second adjusting hole is arranged corresponding to the second fixing hole 421, and a screw or a bolt is inserted into the second fixing hole 421 through the second adjusting hole to connect the second connecting block 40 with the second guide shaft 42. It can be understood that, since the length of the second adjusting hole extends along the width direction F1 of the frame 100, the second adjusting hole is always in communication with the second fixing hole 421 during the adjustment of the second support plate 30 driving the second guide shaft along the width direction F1 of the frame 100, so that when the position of the shower head bottom plate 200 in the width direction F1 of the frame 100 is adjusted, the screw or the bolt is inserted into the second fixing hole 421 through the second adjusting hole corresponding to the second fixing hole 421, thereby connecting the second connecting block 40 with the second guide shaft 42.

[0045] In some embodiments of the present application, please refer to Figure 2 and Figure 3The first adjusting assembly 50 comprises a fixing seat 51, a mounting seat 53 and a first adjusting pin 54. The fixing seat 51 is mounted on the frame 100 and arranged close to the first support plate 10. The mounting seat 53 is mounted on the first support plate 10 and arranged corresponding to the fixing seat 51. The first adjusting pin 54 is movably arranged on the fixing seat 51 and connected with the mounting seat 53, and used to drive the ejection head bottom plate 200 to reciprocate along the frame 100 width direction F1 through the mounting seat 53 and the first support plate 10. Thus, when the first adjusting pin 54 drives the mounting seat 53 to reciprocate along the frame 100 width direction F1, the mounting seat 53 drives the first support plate 10 to reciprocate along the frame 100 width direction F1, and the first support plate 10 drives the ejection head bottom plate 200 to reciprocate along the frame 100 width direction F1, so as to realize the adjustment of the position of the ejection head bottom plate 200 along the frame 100 width direction F1.

[0046] Specifically, referring to Figure 4 and Figure 5 , the fixing seat 51 is provided with a first through hole 52, the axial direction of the first through hole 52 is arranged along the frame 100 width direction F1. The mounting seat 53 is provided with a first connecting hole 531, the axial direction of the first connecting hole 531 is arranged along the frame 100 width direction F1. The first adjusting pin 54 has a length extending along the frame 100 width direction F1. The first adjusting pin 54 is rotatably arranged in the first through hole 52 and inserted into the first connecting hole 531, and threadedly connected with the first connecting hole 531, as shown in Figure 6 . It can be understood that the first connecting hole 531 is a threaded hole, the first adjusting pin 54 is provided with external threads, and when the first adjusting pin 54 is inserted into the first connecting hole 531, the external threads on the first adjusting pin 54 are threadedly connected with the first connecting hole 531. Thus, when the first adjusting pin 54 rotates relative to the fixing seat 51, the external threads on the first adjusting pin 54 are threadedly connected with the first connecting hole 531 on the mounting seat 53, so as to convert the rotating movement of the first adjusting pin 54 into the linear movement of the mounting seat 53 along the frame 100 width direction F1, thereby enabling the mounting seat 53 to reciprocate along the frame 100 width direction F1.

[0047] Optionally, the first adjusting pin 54 is a screw or a bolt.

[0048] Further, referring to Figure 6Two clamping blocks 55 are arranged on the first adjusting pin 54, and are clamped on opposite sides of the fixing seat 51 along the width direction F1 of the frame 100 to limit movement of the first adjusting pin 54 along the width direction F1 of the frame 100. It can be understood that the two clamping blocks 55 limit the first adjusting pin 54 in the width direction F1 of the frame 100, effectively preventing displacement of the first adjusting pin 54 in the width direction F1 of the frame 100 when rotating, so as to effectively convert the rotating movement of the first adjusting pin 54 into linear movement of the mounting seat 53 along the width direction F1 of the frame 100, which is beneficial to improve the adjustment accuracy of the nozzle bottom plate 200 in the width direction F1 of the frame 100.

[0049] In some embodiments of the present application, referring to Figure 4 The fixing seat 51 includes a locking block 511 and a limiting block 512. The locking block 511 is mounted on the frame 100 and is provided with a first semicircular groove 521. The limiting block 512 is arranged on the locking block 511 and is provided with a second semicircular groove 522. The second semicircular groove 522 cooperates with the first semicircular groove 521 to form the first through hole 52. It can be understood that, during assembly, the first adjusting pin 54 is placed in the first semicircular groove 521, the two clamping blocks 55 are clamped on opposite sides of the locking block 511 along the width direction F1 of the frame 100, and then the limiting block 512 is placed on the locking block 511, so that the second semicircular groove 522 on the limiting block 512 cooperates with the first semicircular groove 521 on the locking block 511 to form the first through hole 52.
