Description

Technical Field

[0001] This invention relates to the field of crystal label printer technology, specifically to a printhead mounting mechanism for crystal label printers. Background Technology

[0002] In the printing process of crystal labels, the printhead, as a core component, directly affects the clarity, layering, and detail of the printed pattern due to the stability of its connection with the printer body and the accuracy of its installation and positioning. This plays a decisive role in the final product quality. The printhead mounting mechanism, as a key connection between the printhead and the printer body, primarily provides suitable installation space and basic support for the printhead, ensuring reliable assembly. It also provides a structural foundation for subsequent printhead position adjustment and fixation, meeting the basic requirements of high-precision printing of crystal labels for printhead assembly.

[0003] In existing technologies, printhead fixing methods are often limited to a single direction, making it impossible to flexibly adjust according to actual installation space conditions. When the area above the printhead installation area is obstructed by surrounding components or the space is narrow, additional disassembly or relocation of surrounding components is required to continue the fixing operation. This not only increases the complexity of the installation steps but also easily delays the overall progress due to component disassembly and reassembly. At the same time, given the differences in the internal layout of different printer models, this single fixing structure is difficult to adapt to diverse spatial environments. Whether the space is open or cramped, there is a lack of convenient fixing path selection, resulting in frequent problems such as jamming and difficulty in adjustment during the installation process, leading to low overall installation efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a printhead mounting mechanism for crystal label printers, which solves the problem that the printhead fixing method in existing technologies is often limited to a single direction and cannot be flexibly adjusted according to actual installation space conditions.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a printhead mounting mechanism for a crystal label printer, comprising a mounting base, an adjusting base, and a printhead. A movable disc is rotatably connected to the inner wall of the mounting base. The outer wall of the adjusting base is slidably connected to the inner wall of the movable disc.

A third fixed threaded hole is provided on the outer wall of the printhead. A second fixed threaded hole is provided inside the printhead.

[0006] Preferably, the fixing mechanism includes a rotating column, both ends of which are rotatably connected to the inner wall of the placement groove, and a short column is fixedly connected to the outer wall of the rotating column.

[0007] Preferably, the fixing mechanism further includes a second short column, one end of which is rotatably connected to the end of the first short column away from the rotating column, and the other end of the second short column is fixedly connected to a connecting plate, the outer wall of which is connected to the inner wall of the placement groove.

[0008] Preferably, the fixing mechanism further includes a fixing bolt, the outer wall of which is threadedly connected to the inside of the connecting plate, the outer wall of which is threadedly connected to the inner wall of the second fixing threaded hole, the outer wall of which is threadedly connected to the inner wall of the third fixing threaded hole, the outer wall of which is threadedly connected to the inner wall of the fourth fixing threaded hole, the outer wall of which is threadedly connected to the inner wall of the fifth fixing threaded hole, the outer wall of which is threadedly connected to the inner wall of the seventh fixing threaded hole, and the outer wall of which is threadedly connected to the inner wall of the first fixing threaded hole.

[0009] Preferably, the adjustment mechanism includes a motor, the lower surface of which is fixedly connected to the upper surface of the mounting base, and the output end of the motor is rotatably connected to the inside of the mounting base and fixedly connected to a gear.

[0010] Preferably, the adjusting mechanism further includes a gear ring, the tooth ends of which mesh with the tooth ends of gear one, the inner wall of which is fixedly connected to the outer wall of the movable disk, and the outer wall of which is rotatably connected to the inner wall of the ring groove.

[0011] Preferably, the calibration mechanism includes a slide rail, the lower surface of which is fixedly connected to the upper surface of the mounting base. A limiting hole is formed on the upper surface of the slide rail. A sliding block is slidably connected to the outer wall of the slide rail. A positioning bolt is provided inside the sliding block. The outer wall of the positioning bolt is threadedly connected to the inner wall of the limiting hole.

[0012] Preferably, the calibration mechanism further includes a second slide rail, the lower surface of which is fixedly connected to the upper surface of the mounting base, a second sliding block slidably connected to the outer wall of the second slide rail, a positioning hole fixedly connected to the outer wall of the second sliding block, and the outer wall of the positioning hole slidably connected to the inner wall of the calibration groove.

[0013] Preferably, the calibration mechanism further includes an adjusting rod, one end of which is rotatably connected to the upper surface of the second sliding block, and the other end of which is rotatably connected to the upper surface of the first sliding block.

[0014] Preferably, the calibration mechanism further includes a cylinder, the outer end of which is fixedly connected to the outer wall of the sliding block, a limiting plate is rotatably connected inside the cylinder, a threaded rod is fixedly connected inside the limiting plate, a vertical plate is threadedly connected to the outer wall of the threaded rod, the lower surface of the vertical plate is fixedly connected to the upper surface of the mounting base, and a handwheel is fixedly connected to the outer wall of the threaded rod.

[0015] Working principle: When installing the nozzle, first slide the adjusting seat into the inner wall of the movable plate, then slide the nozzle into the inner wall of the adjusting seat. If it is necessary to fix the nozzle from above, rotate the connecting plate to make it rotate the rotating column through short column two and short column one on the inner wall of the placement slot, and bring the connecting plate out from the inner wall of the placement slot. Then, rotate the connecting plate horizontally to make the fixing bolt rotate to the position aligned with fixing thread hole two. Finally, the fixing bolt can be rotated to pass through fixing thread hole two, fixing thread hole five and fixing thread hole one in sequence to fix the nozzle. When it is necessary to fix the nozzle from the side, use a screwdriver bit to rotate the fixing bolt through fixing thread hole six, so that the fixing bolt passes through fixing thread hole seven, fixing thread hole four on the outer wall of the nozzle and fixing thread hole three on the outer wall of the nozzle in sequence to fix the nozzle from the side.

[0016] When the motor starts, its output end drives gear one to rotate synchronously. Since the tooth end of gear one meshes with the tooth end of the gear ring, the rotational force of gear one is transmitted to the gear ring, causing the gear ring to rotate circumferentially along the ring groove on the inner wall of the mounting base. The inner wall of the gear ring is fixedly connected to the outer wall of the movable disk. Therefore, the rotation of the gear ring synchronously drives the movable disk to rotate with it. The rotation direction of the movable disk can be flexibly controlled by the forward and reverse rotation of the motor, thereby adjusting the angle position of the movable disk.

[0017] When the handwheel is turned, the threaded rod rotates synchronously with it. Since the threaded rod is threadedly connected to the vertical plate, the rotational motion is converted into linear motion of the threaded rod along the axis. The threaded rod pushes the cylinder through the limiting plate, causing the first sliding block to slide along the first slide rail. The sliding of the first sliding block drives the two ends of the adjusting rod to rotate, which in turn pulls the second sliding block to slide synchronously along the second slide rail. When the second sliding block moves, the positioning hole on its outer wall slides along the inner wall of the calibration groove to achieve calibration. After calibration to the target position, the positioning bolt is screwed into the inside of the first sliding block and screwed into the limiting hole of the first slide rail to lock the position of the first sliding block and complete the calibration.

[0018] This invention provides a printhead mounting mechanism for a crystal label printer. It offers the following advantages:

[0019] 1. By setting up a fixing mechanism, the present invention can quickly and directly fix the printhead from above when there is ample space above it. If the space above is blocked by other components or is narrow, it can seamlessly switch to a horizontal fixing method without moving surrounding components. Facing the differences in internal layout of different printer models or complex installation environments, whether the space is cramped or open, a convenient fixing path can be found, getting rid of the scene limitations brought about by a single fixing direction, and making the installation process always smooth and efficient.

[0020] 2. This invention, by setting an adjustment mechanism, utilizes the meshing transmission between the motor-driven gear and the gear ring to achieve electric adjustment of the movable disc angle. There is no need to manually rotate the movable disc, making the adjustment process more labor-saving and more accurate. It can quickly adjust the movable disc to the optimal angle for nozzle installation, reducing the difficulty of subsequent fixing operations.

[0021] 3. The fixing bolts of the present invention are always pre-fixed inside the connecting plate, and when not in use, they are stored together with the connecting plate in the placement slot. They do not need to be stored separately or taken out separately, which avoids the problem of fixing bolts falling off or being lost in traditional installation, reduces the wear and tear of accessories, and does not require interruption of the installation process due to missing fixing bolts.

[0022] 4. This invention, by setting up a calibration mechanism and utilizing the threaded transmission of the handwheel and the threaded rod, achieves micro-adjustment of the sliding block one, which can control the position error of the printhead within a very small range, ensuring the accurate relative position of the printhead and the medium during printing. The sliding block one along the slide rail one and the sliding block two along the slide rail two slide smoothly without jamming. With the transmission of the adjusting rod, positional deviation or jamming during calibration is avoided. The locking of the positioning bolt and the limiting hole ensures that the position is stable after calibration and is not affected by vibration, ultimately ensuring that the printed pattern of the crystal label has clear edges and accurate position.

Detailed Implementation

[0033] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see the appendix Figure 1 -Appendix Figure 9This invention provides a printhead mounting mechanism for a crystal label printer, including a mounting base 1, an adjusting base 4, and a printhead 5. A movable disk 2 is rotatably connected to the inner wall of the mounting base 1. The outer wall of the adjusting base 4 is slidably connected to the inner wall of the movable disk 2. The outer wall of the printhead 5 is slidably connected to the inner wall of the adjusting base 4. A first fixed threaded hole 3 is provided inside the movable disk 2. A fourth fixed threaded hole 8 is provided on the outer wall of the adjusting base 4. A fifth fixed threaded hole 9 is provided on the upper surface of the adjusting base 4. A third fixed threaded hole 7 is provided on the outer wall of the printhead 5. A second fixed threaded hole 6 is provided inside the printhead 5. A sixth fixed threaded hole 10 and a seventh fixed threaded hole 11 are provided inside the movable disk 2, and the sixth and seventh fixed threaded holes 10 and 11 are on the same axis. A placement groove 12 is provided at the upper end of the movable disk 2. An annular groove 21 is provided on the inner wall of the mounting base 1. A calibration groove 22 is provided on the outer wall of the movable disk 2. A fixing mechanism is provided inside the movable disk 2. An adjusting mechanism and a calibration mechanism are provided on the upper surface of the mounting base 1.

[0035] The specific annular groove 21 is used to provide rotation space for the movable disk 2 and to limit the toothed ring 20. The fixed threaded holes 10, 11, 8, and 7 are used to fix the printhead 5 in the lateral direction. The fixed threaded holes 6, 9, and 3 are used to fix it in the longitudinal direction. The fixing mechanism is used to fix the printhead 5 from the side and top. The adjustment mechanism can quickly adjust the movable disk 2 to the optimal angle for the installation of the printhead 5, reducing the difficulty of subsequent fixing operations. The calibration mechanism can control the position error of the printhead 5 to a very small range, ensuring that the relative position of the printhead 5 and the media is accurate during printing.

[0036] The fixing mechanism includes a rotating column 13, both ends of which are rotatably connected to the inner wall of the placement groove 12. A short column 14 is fixedly connected to the outer wall of the rotating column 13. The fixing mechanism also includes a short column 2 15, one end of which is rotatably connected to the end of the short column 14 away from the rotating column 13. A connecting plate 16 is fixedly connected to the other end of the short column 2 15. The outer wall of the connecting plate 16 is connected to the inner wall of the placement groove 12. The fixing mechanism also includes a fixing bolt 17, the outer wall of which is threadedly connected to the inside of the connecting plate 16. The outer wall of the fixing bolt 17 is threadedly connected to the inner wall of the second fixing threaded hole 6, the third fixing threaded hole 7, the fourth fixing threaded hole 8, the fifth fixing threaded hole 9, the seventh fixing threaded hole 11, and the first fixing threaded hole 3.

[0037] Specifically, when installing the nozzle 5, first slide the adjusting seat 4 into the inner wall of the movable plate 2, then slide the nozzle 5 into the inner wall of the adjusting seat 4. If it is necessary to fix the nozzle 5 from above, rotate the connecting plate 16 to make it rotate the rotating column 13 on the inner wall of the placement groove 12 through the short column 2 15 and the short column 1 14, and bring the connecting plate 16 out from the inner wall of the placement groove 12. Then, rotate the connecting plate 16 horizontally to make the fixing bolt 17 rotate to the position aligned with the fixing threaded hole 2 6. Finally, the fixing bolt 17 can be rotated to pass through the fixing threaded hole 2 6, the fixing threaded hole 5 9 and the fixing threaded hole 1 3 in sequence to fix the nozzle 5. When it is necessary to fix the nozzle 5 from the side, use a screwdriver or similar tool to rotate the fixing bolt 17 through the fixing threaded hole 6 10 to make the fixing bolt 17 pass through the fixing threaded hole 7 11, the fixing threaded hole 4 8 on the outer wall of the nozzle 5 and the fixing threaded hole 3 7 on the outer wall of the nozzle 5 in sequence to fix the nozzle 5 from the side.

[0038] When there is ample space above the printhead 5, it can be quickly fixed directly from above. If the space above is blocked by other components or is narrow, it can be seamlessly switched to a horizontal fixing method without moving surrounding components. Facing the differences in internal layout of different printer models or complex installation environments, whether the space is cramped or open, a convenient fixing path can be found, getting rid of the scene limitations brought by a single fixing direction, and making the installation process always smooth and efficient.

[0039] The fixing bolt 17 is always pre-fixed inside the connecting plate 16 and is stored in the placement slot 12 along with the connecting plate 16 when not in use. It does not need to be stored separately or taken out separately, which avoids the problem of fixing bolt 17 being easy to fall off or be lost in traditional installation, reduces the wear and tear of accessories, and does not interrupt the installation process due to the absence of fixing bolt 17. The fixing bolt 17 stored in the placement slot 12 can prevent external dust from adhering or accidental collisions from causing thread damage, ensuring the connection accuracy of fixing bolt 17. At the same time, it prevents the unstored fixing bolt 17 from scratching the surface of precision components such as nozzle 5 and adjustment seat 4, reducing the risk of component damage before installation, and further improving the smoothness of the installation process and the service life of components.

[0040] The adjustment mechanism includes a motor 18, the lower surface of which is fixedly connected to the upper surface of the mounting base 1, and the output end of the motor 18 is rotatably connected to the inside of the mounting base 1 and fixedly connected to a gear 19. The adjustment mechanism also includes a gear ring 20, the tooth end of which meshes with the tooth end of the gear 19, the inner wall of the gear ring 20 is fixedly connected to the outer wall of the movable disk 2, and the outer wall of the gear ring 20 is rotatably connected to the inner wall of the ring groove 21.

[0041] Specifically, when the motor 18 starts, its output end drives the gear 19 to rotate synchronously. Since the tooth end of the gear 19 meshes with the tooth end of the gear ring 20, the rotational force of the gear 19 is transmitted to the gear ring 20, causing the gear ring 20 to rotate circumferentially along the annular groove 21 on the inner wall of the mounting base 1. The inner wall of the gear ring 20 is fixedly connected to the outer wall of the movable disk 2. Therefore, the rotation of the gear ring 20 synchronously drives the movable disk 2 to rotate with it. The rotation direction of the movable disk 2 can be flexibly controlled by the forward and reverse rotation of the motor 18, thereby adjusting the angle position of the movable disk 2.

[0042] The electric adjustment of the angle of the movable disc 2 is achieved by the meshing transmission of the gear 19 driven by the motor 18 and the gear ring 20. The movable disc 2 does not need to be manually rotated, making the adjustment process less labor-intensive and more precise. It can quickly adjust the movable disc 2 to the optimal angle for the installation of the nozzle 5, reducing the difficulty of subsequent fixing operations. At the same time, the rotation of the gear ring 20 in the ring groove 21 is stable and without jamming, avoiding the displacement of the movable disc 2 caused by uneven force during manual adjustment, ensuring the stability of the position of the movable disc 2 after adjustment, and laying the foundation for the stable installation of the nozzle 5.

[0043] The calibration mechanism includes a slide rail 23, the lower surface of which is fixedly connected to the upper surface of the mounting base 1. A limiting hole 25 is formed on the upper surface of the slide rail 23. A sliding block 26 is slidably connected to the outer wall of the slide rail 23. A positioning bolt 27 is provided inside the sliding block 26, and the outer wall of the positioning bolt 27 is threadedly connected to the inner wall of the limiting hole 25. The calibration mechanism also includes a slide rail 24, the lower surface of which is fixedly connected to the upper surface of the mounting base 1. A sliding block 29 is slidably connected to the outer wall of the slide rail 24. A positioning hole 30 is fixedly connected to the outer wall of the sliding block 29, and the outer wall of the positioning hole 30 is slidably connected to the calibration base 1. The inner wall of the groove 22; the calibration mechanism also includes an adjusting rod 28, one end of which is rotatably connected to the upper surface of the second sliding block 29, and the other end of which is rotatably connected to the upper surface of the first sliding block 26; the calibration mechanism also includes a cylinder 33, the outer end of which is fixedly connected to the outer wall of the first sliding block 26, a limiting piece 32 is rotatably connected inside the cylinder 33, a threaded rod 31 is fixedly connected inside the limiting piece 32, a vertical plate 35 is threadedly connected to the outer wall of the threaded rod 31, the lower surface of the vertical plate 35 is fixedly connected to the upper surface of the mounting base 1, and a handwheel 34 is fixedly connected to the outer wall of the threaded rod 31.

[0044] Specifically, when the handwheel 34 is turned, the threaded rod 31 rotates synchronously with it. Since the threaded rod 31 is threadedly connected to the vertical plate 35, the rotational motion is converted into linear motion of the threaded rod 31 along the axis. The threaded rod 31 pushes the cylinder 33 through the limiting piece 32, causing the sliding block 26 to slide along the slide rail 23. The sliding of the sliding block 26 drives the two ends of the adjusting rod 28 to rotate, thereby pulling the sliding block 29 to slide synchronously along the slide rail 24. When the sliding block 29 moves, the positioning hole 30 on its outer wall slides along the inner wall of the calibration groove 22 to achieve calibration. After calibration to the target position, the positioning bolt 27 is screwed into the sliding block 26 and screwed into the limiting hole 25 of the slide rail 23 to lock the position of the sliding block 26 and complete the calibration.

[0045] The screw drive between the handwheel 34 and the screw rod 31 enables the micro-adjustment of the sliding block 26, which can control the position error of the printhead 5 within a very small range, ensuring the precise relative position of the printhead 5 and the medium during printing. The sliding block 26 slides smoothly along the slide rail 23 and the sliding block 29 slides smoothly along the slide rail 24 without jamming. With the transmission of the adjusting rod 28, positional deviation or jamming during calibration is avoided. The locking of the positioning bolt 27 and the limiting hole 25 ensures that the position is stable after calibration and is not affected by vibration, ultimately ensuring that the printed pattern of the crystal label has clear edges and accurate position.
