Description

Technical Field

[0001] This application relates to the technical field of inkjet printing equipment, and in particular to an ink line position correction device for an inkjet printer. Background Technology

[0002] Inkjet printers are devices that use non-contact methods to print patterns, text, and numbers on the surfaces of various objects. The principle of a continuous inkjet printer is as follows: Under the pressure applied by the ink supply pump, ink flows from the ink tank through the ink path pipes and enters the ink gun after the pressure and viscosity are adjusted. Subsequently, the ink is ejected at high speed from the nozzle. As the ink passes through the nozzle, it breaks into a series of continuous, equally spaced, and uniformly sized droplets under the action of piezoelectric crystals. These droplets continue to move, and when they pass through the charging tank, they are charged by the charging electrodes in the charging tank. The voltage applied to the charging electrodes causes the droplets to carry a charge proportional to the voltage. Then, the droplets pass between deflection plates with positive and negative voltages respectively. The charged droplets are deflected as they pass through the deflection plates, and the degree of deflection varies depending on the amount of charge they carry. Finally, they fall onto the product surface at a certain speed and angle to form the code, while the uncharged droplets are not deflected and are directly ejected into the recovery tube, returning to the ink tank for recycling.

[0003] In the actual operation of inkjet printers, the charging slot is generally designed to have strict planar symmetry along the ink line flight direction. This characteristic often makes it difficult to adjust the position of the charging slot relative to the ink line. Furthermore, to align the ink line with the recovery tube's inlet, the nozzle position needs multi-dimensional adjustment. Common adjustment methods include using a horizontal cam to drive the nozzle to rotate along a fixed vertical axis to adjust the nozzle's horizontal angle, and using a vertical cam to drive the nozzle to rotate along a fixed horizontal axis to adjust the nozzle's height, thereby aligning the ink line with the recovery tube's inlet.

[0004] Regarding the aforementioned technologies, since most inkjet printers currently use a fixed rotating shaft as the reference component for adjusting the nozzle position, certain errors are inevitable during the manufacturing process due to the difficulty in achieving absolute high precision. When adjusting the nozzle position based on a rotating shaft with errors, although the nozzle can be aligned with the collection port and the ink droplet recovery system can function normally, if the position of the ink line in the charging tank deviates when the ink line passes through it—that is, if the ink line is not within the symmetrical plane of the charging tank—it will lead to deviations in the ink droplet charging data. This, in turn, will cause deviations in the deflection effect of the ink droplets between the deflection plates, ultimately severely affecting the quality of the inkjet printing. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, one of the objectives of this invention is to provide an ink line position correction device for inkjet printers.

[0006] This application provides a coding machine ink line position correction device, which adopts the following technical solution: The ink line position correction device for an inkjet printer includes a base plate, a nozzle position adjustment assembly for mounting nozzles, a translation adjustment shaft, and a fixed shaft for limiting the axial translation of the translation adjustment shaft. The nozzle position adjustment assembly has a first oblong hole, the length direction of which is parallel to the axial direction of the translation adjustment shaft. The fixed shaft passes through the first oblong hole and is mounted on the base plate. The nozzle position adjustment assembly is configured to rotate around the fixed shaft. The translation adjustment shaft has an annular groove that mates with the fixed shaft. The translation adjustment shaft passes through the nozzle position adjustment assembly and is threadedly engaged with it. The fixed shaft is located within the annular groove on the translation adjustment shaft.

[0007] By adopting the above technical solution, the fixed shaft and the nozzle position adjustment component are threaded together. When the translation adjustment shaft is rotated, the limiting effect of the fixed shaft converts the rotation of the translation adjustment shaft into the axial movement of the nozzle position adjustment component, realizing the horizontal translation of the nozzle. When there is an angular deviation in the nozzle, rotating the nozzle position adjustment component causes the nozzle to rotate around the axis of the fixed shaft with the fixed shaft as the rotation center. This ensures that the adjustment of the nozzle position can be converted into a corresponding change in the ink line position, ensuring that the ink line reaches the collection port during the operation of the inkjet printer, while also ensuring that the ink line is within the symmetrical plane of the charging tank. This ensures accurate ink droplet charging data and reduces the quality problem of blurry coding caused by ink line deviation.

[0008] Preferably, the nozzle position adjustment assembly is provided with a plurality of limiting clamps, which are sleeved on the translation adjustment shaft. The plurality of limiting clamps are used to apply radial constraints to the translation adjustment shaft, and the plurality of limiting clamps allow the translation adjustment shaft to rotate along its own axis.

[0009] By adopting the above technical solution, the limiting clamp fitted onto the translation adjustment shaft can effectively limit the radial wobble of the translation adjustment shaft caused by external force or vibration during the adjustment process, ensuring that the fixed shaft slides relative to the axial direction of the translation adjustment shaft within the first oblong hole, thus converting the action of rotating the translation adjustment shaft into linear displacement of the nozzle position adjustment assembly. Simultaneously, it avoids calibration errors caused by translation deviation or adjustment jamming due to translation adjustment shaft offset.

[0010] Preferably, it further includes a first eccentric cam, which comprises a first base cylinder and a first eccentric cylinder. The first eccentric cylinder is fixed on the first base cylinder, and the axis of the first eccentric cylinder does not coincide with the axis of the first base cylinder. The base plate has a second oblong hole, and the fixing shaft is located on the extension line of the center line of the second oblong hole along its length direction. The nozzle position adjustment assembly has a first through hole. The first base cylinder is embedded in the second oblong hole and moves along the length direction of the second oblong hole. The first eccentric cylinder is rotatably installed in the first through hole.

[0011] By adopting the above technical solution, when the nozzle position adjustment component is adjusted for translation and angle, the first base cylinder rotates and moves in the second waist-shaped hole, and the first eccentric cylinder drives the nozzle position adjustment component to move or rotate. With the positioning of the fixed shaft, the translation and angle adjustment of the nozzle position adjustment component and the nozzle are realized, further ensuring that the ink line passes through the symmetrical plane of the charging tank and reaches the recycling port.

[0012] Preferably, the axis of the fixed shaft and the axis of the recycling tube are located in the plane of symmetry of the charging tank, and the plane of symmetry is perpendicular to the direction of the axis of the translation adjustment shaft.

[0013] By adopting the above technical solution, the axis of the fixed shaft and the axis of the recovery tube are located in the symmetrical plane of the charging tank. This ensures that when the nozzle position adjustment component is translated or rotated, the position change of the nozzle directly corresponds to the offset or angular deflection of the ink line in the symmetrical plane. This makes the ink line alignment operation more convenient and efficient, and reduces the calibration time and quality risks caused by inconsistent spatial references.

[0014] Preferably, the nozzle position adjustment assembly has a first arc-shaped through hole and a second arc-shaped through hole. The first arc-shaped through hole and the second arc-shaped through hole are arc-shaped and are both configured with the axis of the fixed shaft as the center. A first locking screw is provided in the first arc-shaped through hole and a second locking screw is provided in the second arc-shaped through hole. The first locking screw passes through the first arc-shaped through hole and the second locking screw passes through the second arc-shaped through hole, connecting and locking the nozzle position adjustment assembly and the base plate.

[0015] By adopting the above technical solution, the first arc-shaped through hole and the second arc-shaped through hole serve as the first locking screw and the second locking screw, providing displacement space during translation or rotation. This allows the operator to adjust the nozzle position by loosening the first locking screw and the second locking screw without completely disassembling the connecting parts, significantly improving the convenience of the calibration operation.

[0016] Preferably, the nozzle position adjustment assembly includes a nozzle adjustment bracket and a nozzle fixing bracket. The nozzle adjustment bracket includes an assembly part and an adjustment part. The adjustment part is perpendicular to the assembly part. The assembly part is assembled to a fixed shaft. The translation adjustment shaft passes through the adjustment part. The nozzle fixing bracket is installed on the side of the assembly part away from the base plate. The nozzle fixing bracket has a mounting hole for installing the nozzle.

[0017] By adopting the above technical solution, the translation adjustment shaft passes through the adjustment part perpendicular to the assembly part and cooperates with the fixed shaft, converting rotational motion into linear displacement, which significantly improves calibration efficiency. At the same time, the mounting holes opened in the nozzle fixing bracket provide a stable installation for the nozzle, so that the positional changes of the nozzle adjustment bracket can be transmitted to the nozzle without deviation, ensuring that the ink line position changes accurately with the adjustment action.

[0018] Preferably, it further includes a second eccentric cam, which comprises a second base cylinder and a second eccentric cylinder. The second eccentric cylinder is fixed on the second base cylinder, and the axis of the second eccentric cylinder does not coincide with the axis of the second base cylinder. The adjusting part is provided with a fixing frame rotating shaft for rotating the nozzle fixing frame. The fixing frame rotating shaft passes through the adjusting part and the nozzle fixing frame in sequence. The nozzle fixing frame is provided with a third oblong hole. The fixing frame rotating shaft is located on the extension line of the center line of the third oblong hole along its length direction. The adjusting part is provided with a second through hole. The second base cylinder is embedded in the third oblong hole and moves within the third oblong hole. The second eccentric cylinder is rotatably installed in the second through hole.

[0019] By adopting the above technical solution, the second eccentric cylinder is rotated, causing the second base cylinder to rotate and displace within the third oblong hole. This causes the second base cylinder to push the nozzle holder to rotate around the rotating axis of the holder, thereby causing the nozzle mounted on the holder to synchronously adjust its vertical angle, so that the ink line can be aligned with the recovery tube in the vertical direction.

[0020] Preferably, the adjusting part is provided with a third arc-shaped through hole, the third arc-shaped through hole is arc-shaped and is configured with the axis of the rotating shaft of the fixing frame as the center, and a third locking screw is provided in the third arc-shaped through hole, the third locking screw passes through the third arc-shaped through hole, and connects and locks the adjusting part and the nozzle fixing frame.

[0021] By adopting the above technical solution, after the nozzle fixing bracket is adjusted to the correct position, tightening the third locking screw effectively resists vibration or external force during equipment operation, prevents the nozzle fixing bracket from shifting, and ensures long-term stability of the nozzle's vertical angle adjustment accuracy.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The fixed shaft and the nozzle position adjustment component are threaded together. When the translation adjustment shaft is rotated, the limiting action of the fixed shaft converts the rotation of the translation adjustment shaft into the axial movement of the nozzle position adjustment component, realizing the horizontal translation of the nozzle. When there is an angular deviation in the nozzle, rotating the nozzle position adjustment component causes the nozzle to rotate around the axis of the fixed shaft with the fixed shaft as the rotation center. This ensures that the adjustment of the nozzle position is translated into a corresponding change in the ink line position, ensuring that the ink line reaches the collection port during operation and is within the symmetrical plane of the charging tank. This ensures accurate ink droplet charging data and reduces the quality problems of blurry coding caused by ink line deviation. 2. The limiting clamp fitted onto the translation adjustment shaft effectively restricts the radial wobble of the translation adjustment shaft caused by external force or vibration during adjustment, ensuring that the fixed shaft slides relative to the axial direction of the translation adjustment shaft within the first oblong hole, thus converting the rotation of the translation adjustment shaft into linear displacement of the nozzle position adjustment assembly. Simultaneously, it avoids calibration errors caused by translation deviation or adjustment jamming due to translation adjustment shaft offset. 3. When adjusting the nozzle position adjustment component for translation and angle, the first base cylinder rotates and moves in the second waist-shaped hole, and the first eccentric cylinder drives the nozzle position adjustment component to move or rotate. With the positioning of the fixed shaft, the translation and angle adjustment of the nozzle position adjustment component and the nozzle are realized, further ensuring that the ink line passes through the symmetrical plane of the charging tank and reaches the recycling port.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0026] This application discloses an ink line position correction device for an inkjet printer.

[0027] Reference Figure 1 and Figure 2 A coding machine ink line position correction device includes a base plate 4, a nozzle position adjustment assembly 5 for mounting a nozzle 1, a translation adjustment shaft 6, and a fixed shaft 7 for limiting the axial translation of the translation adjustment shaft 6. The nozzle position adjustment assembly 5 has a first oblong hole 8, the length direction of which is parallel to the axial direction of the translation adjustment shaft 6. The fixed shaft 7 passes through the first oblong hole 8 and is mounted on the base plate 4. The nozzle position adjustment assembly 5 is configured to rotate around the fixed shaft 7. The translation adjustment shaft 6 has an annular groove 9 that mates with the fixed shaft 7. The translation adjustment shaft 6 passes through the nozzle position adjustment assembly 5 and is threadedly engaged with the nozzle position adjustment assembly 5. The fixed shaft 7 is located within the annular groove 9 of the translation adjustment shaft 6.

[0028] When the nozzle 1 needs to be angularly adjusted, rotate the nozzle position adjustment component 5. The nozzle position adjustment component 5 rotates around the fixed shaft 7 as the rotation center, driving the nozzle 1 to rotate around the axis of the fixed shaft 7, thereby achieving the angle adjustment of the nozzle position adjustment component 5 with the fixed shaft 7 as the rotation axis. When the nozzle 1 needs to be translated, rotate the translation adjustment shaft 6. Since the fixed shaft 7 is located on the base plate 4 and inside the annular groove 9, the translation adjustment shaft 6 is limited and cannot move axially. The translation adjustment shaft 6 will push or pull the nozzle position adjustment component 5 to move along the axial direction of the translation adjustment shaft 6, so that the ink line is in the symmetrical plane of the charging tank 2, thereby achieving the positional calibration of the ink line with the charging tank 2 and the recycling tube 3.

[0029] Reference Figure 1 and Figure 2 The nozzle position adjustment assembly 5 is equipped with several limiting clamps 10, which are sleeved on the translation adjustment shaft 6. These limiting clamps 10 apply radial constraints to the translation adjustment shaft 6 and allow the translation adjustment shaft 6 to rotate along its own axis. When the translation adjustment shaft 6 is rotated to adjust the ink line translation, the limiting clamps 10 restrict the radial displacement of the translation adjustment shaft 6, ensuring that the nozzle position adjustment assembly 5 slides precisely along the axial direction of the translation adjustment shaft 6 and preventing deviations in the translation amount of the nozzle position adjustment assembly 5 due to radial wobbling of the translation adjustment shaft 6.

[0030] Reference Figure 3 The translation adjustment shaft 6, located away from the annular groove 9, has a threaded section 11 on its outer circumference. A corresponding through hole is provided on the nozzle position adjustment assembly 5 through which the translation adjustment shaft 6 passes. Its inner wall has an internal threaded area 12 that mates with the threaded section 11. The threaded section 11 of the translation adjustment shaft 6 is threadedly engaged with the internal threaded area 12 of the nozzle position adjustment assembly 5. During the translation adjustment process of the nozzle position adjustment assembly 5, the axial position of the nozzle position adjustment assembly 5 along the translation adjustment shaft 6 can be adjusted by rotating the threaded section 11 of the translation adjustment shaft 6.

[0031] Reference Figure 4 and Figure 5 The ink line position correction device for a coding machine disclosed in this application embodiment further includes a first eccentric cam 13. The first eccentric cam 13 includes a first base cylinder 131 and a first eccentric cylinder 132. The first eccentric cylinder 132 is fixed on the first base cylinder 131, and the axis of the first eccentric cylinder 132 does not coincide with the axis of the first base cylinder 131. The base plate 4 is provided with a second oblong hole 14. The fixing shaft 7 is located on the extension line of the center line of the second oblong hole 14 along the length direction. The nozzle position adjustment component 5 is provided with a first through hole 15. The first base cylinder 131 is embedded in the second oblong hole 14 and moves along the length direction of the second oblong hole 14. The first eccentric cylinder 132 is rotatably installed in the first through hole 15. When the nozzle position adjustment assembly 5 is translated, the first base cylinder 131 in the second waist-shaped hole 14 moves within the second waist-shaped hole 14 as the nozzle position adjustment assembly 5 moves. Since the first eccentric cylinder 132 is embedded in the first through hole 15, it drives the nozzle 1 installed on the nozzle position adjustment assembly 5 to complete the translation adjustment. When the nozzle position adjustment assembly 5 is angled, the first eccentric cam 13 is rotated to achieve the angle adjustment of the nozzle position adjustment assembly 5 with the fixed shaft 7 as the rotation axis.

[0032] Reference Figure 2The axis of the fixed shaft 7 and the axis of the recovery tube 3 are located within the plane of symmetry of the charging tank 2, and this plane of symmetry is perpendicular to the axis of the translation adjustment shaft 6. The fact that the axis of the fixed shaft 7 and the axis of the recovery tube 3 are located within the plane of symmetry of the charging tank 2 ensures that when the nozzle position adjustment assembly 5 is translated or rotated, the position change of the nozzle 1 directly corresponds to the offset or angular deflection of the ink line within this plane of symmetry, thus improving the adjustment efficiency of the ink line alignment with the charging tank 2 and the recovery tube 3.

[0033] Reference Figure 2 and 4 The nozzle position adjustment assembly 5 has a first arc-shaped through hole 16 and a second arc-shaped through hole 17. Both the first arc-shaped through hole 16 and the second arc-shaped through hole 17 are arc-shaped and are both positioned with the axis of the fixed shaft 7 as the center. A first locking screw 18 is installed in the first arc-shaped through hole 16, and a second locking screw 19 is installed in the second arc-shaped through hole 17. The first locking screw 18 passes through the first arc-shaped through hole 16, and the second locking screw 19 passes through the second arc-shaped through hole 17, connecting and locking the nozzle position adjustment assembly 5 and the base plate 4. After the position of the nozzle 1 is adjusted by translation or rotation, the first locking screw 18 and the second locking screw 19 are tightened to fix the position of the nozzle position adjustment assembly 5 and prevent the position of the nozzle 1 from shifting due to vibration.

[0034] Reference Figure 3 and Figure 4 The nozzle position adjustment assembly 5 includes a nozzle adjustment bracket 51 and a nozzle fixing bracket 52. The nozzle adjustment bracket 51 includes an assembly part 511 and an adjustment part 512. The adjustment part 512 is perpendicular to the assembly part 511. The assembly part 511 is mounted on a fixed shaft 7. A translation adjustment shaft 6 passes through the adjustment part 512. The nozzle fixing bracket 52 is installed on the side of the assembly part 511 away from the base plate 4. The nozzle fixing bracket 52 has a mounting hole 20 for mounting the nozzle.

[0035] The ink line position correction device for a coding machine disclosed in this application embodiment further includes a second eccentric cam 21. The second eccentric cam 21 includes a second base cylinder 211 and a second eccentric cylinder 212. The second eccentric cylinder 212 is fixed on the second base cylinder 211, and the axis of the second eccentric cylinder 212 does not coincide with the axis of the second base cylinder 211. The adjusting part 512 is provided with a fixing frame rotating shaft 22 for rotating the nozzle fixing frame 52. The fixing frame rotating shaft 22 passes through the adjusting part 512 and the nozzle fixing frame 52 in sequence. The nozzle fixing frame 52 is provided with a third oblong hole 23. The fixing frame rotating shaft 22 is located on the extension line of the center line of the third oblong hole 23 along the length direction. The adjusting part 512 is provided with a second through hole 24. The second base cylinder 211 is embedded in the third oblong hole 23 and moves within the third oblong hole 23. The second eccentric cylinder 212 is rotatably installed in the second through hole 24. When vertical adjustment of nozzle 1 is required, the second eccentric cam 21 is rotated, causing the second base cylinder 211 to rotate and move within the third oblong hole 23 of nozzle holder 52. Simultaneously, the holder rotation shaft 22 passes through the adjustment section 512 and the nozzle holder 52. The nozzle holder 52 rotates around the holder rotation shaft 22, causing the nozzle holder 52 and the nozzle 1 mounted on it to simultaneously undergo vertical angular deflection, ensuring accurate ink jetting to the recovery tube 3.

[0036] The adjusting part 512 has a third arc-shaped through hole 25. The third arc-shaped through hole 25 is arc-shaped and is arranged with the axis of the rotating shaft 22 of the fixing frame as the center. A third locking screw 26 is provided in the third arc-shaped through hole 25. The third locking screw 26 passes through the third arc-shaped through hole 25, connecting and locking the adjusting part 512 and the nozzle fixing frame 52. After the nozzle 1 is adjusted in the vertical direction, the nozzle fixing frame 52 is locked and fixed to the nozzle adjusting frame 51 by the cooperation of the third arc-shaped through hole 25 and the third locking screw 26. This prevents the nozzle fixing frame 52 from rotating due to equipment vibration or external force, and ensures the adjustment accuracy of the nozzle 1 in the vertical direction.

[0037] The implementation principle of this application embodiment is as follows: When it is necessary to calibrate the position of the ink line of the inkjet printer, the operator first adjusts the angle of the ink line in the horizontal plane. By rotating the first eccentric cam 13, the first base cylinder 131 rotates and is displaced in the second oblong hole 14 of the base plate 4. This causes the first eccentric cylinder 132 to push the nozzle position adjustment assembly 5 to rotate around the fixed shaft 7 as the rotation center, thereby causing the nozzle 1 to produce a horizontal angle deflection. This allows the nozzle 1 installed on the nozzle position adjustment assembly 5 to complete the horizontal angle adjustment, so that the ink line is initially aligned with the charging tank 2 and the recycling tube 3.

[0038] After the angle adjustment in the horizontal plane is completed, the nozzle position adjustment assembly 5 is axially displaced relative to the fixed shaft 7 and the base plate 4 by rotating the translation adjustment shaft 6. During this process, the first base cylinder 131 rotates and moves within the second oblong hole 14 of the base plate 4, thereby driving the first eccentric cylinder 132 to move, so that the ink line is further aligned with the charging tank 2 and the recycling tube 3.

[0039] If the pitch angle of nozzle 1 needs to be adjusted, the operator rotates the second eccentric cam 21, causing the second eccentric cylinder 212 to rotate within the second through hole 24. This causes the second base cylinder 211 to rotate and displace within the third waist-shaped hole 23. Consequently, the second base cylinder 211 pushes the nozzle holder 52 to rotate around the holder rotation axis 22, thereby adjusting the pitch angle of nozzle 1 mounted on the nozzle holder 52 and ensuring that the ink line can be accurately injected into the recovery tube 3.

[0040] After adjusting the translation, horizontal angle, and pitch angle of nozzle 1, the operator tightens the first locking screw 18 and the second locking screw 19 respectively to fix the nozzle position adjustment assembly 5 to the base plate 4. Simultaneously, the third locking screw 26 is tightened to lock the nozzle fixing bracket 52 onto the nozzle adjustment bracket 51. This effectively prevents the nozzle 1 from shifting due to vibration during equipment operation, ensuring the long-term stability of the ink line position calibration.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
