Description

Technical Field

[0001] The invention belongs to the technical field of inkjet printing, and in particular relates to a longitudinal moving device of an ink carriage of an inkjet printer. Background Art

[0002] As an efficient and precise printing mechanism that does not require a printing plate, inkjet printers are widely used in many fields such as graphic printing and packaging printing. Among them, the ink carriage, as one of the core components of the inkjet printer, is responsible for carrying the nozzle to move longitudinally above the printing medium to achieve continuous and uniform inkjet printing. The longitudinal movement device of the ink carriage is not only required to have precise positioning capabilities, but also to be able to drive the ink carriage to switch quickly and accurately between different positions in the printing area, ensuring that the ink droplets can be accurately sprayed onto the printing medium according to the preset pattern and position. This precise longitudinal movement is the basis for achieving high-quality printing effects. Whether it is for the printing of text, images or complex patterns, it is inseparable from the stable and precise longitudinal movement of the ink carriage.

[0003] However, the existing ink carriage longitudinal moving device of the inkjet printer has many deficiencies in practical application. During high-speed printing operation, the ink carriage needs to frequently perform emergency stop and start operations during high-speed movement, and the emergency stop situation is relatively frequent. This drastic change in motion state leads to poor dynamic stability of the ink carriage, especially when it suddenly stops at high speed. The ink carriage is prone to shaking and offset due to inertia, which in turn affects the precise positioning of the printed pattern, reduces the accuracy and consistency of inkjet, and causes problems such as ink drop position deviation and blurred lines in the printed products, seriously reducing the printing quality; and frequent emergency stops and starts and shaking offsets will not only increase the mechanical wear of the ink carriage and shorten its service life, but also increase the maintenance cost and failure rate of the equipment; therefore, there are deficiencies and it cannot meet the user's usage needs. Therefore, further improvement is necessary.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an ink carriage longitudinal moving device of an inkjet printer is provided, in order to achieve a purpose with greater practical value. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a longitudinal moving device of an ink carriage of an inkjet printer, which is achieved by the following specific technical means:

[0006] An ink carriage longitudinal movement device for an inkjet printer comprises a machine base and an ink carriage, a height adjustment mechanism disposed on the machine base, and a longitudinal movement mechanism disposed on the height adjustment mechanism, and further comprises a stabilizing component disposed on the longitudinal movement mechanism;

[0007] The stabilizing assembly includes a stabilizing slide bar and a stabilizing slider. The stabilizing slider is slidably mounted on the stabilizing slide bar. A groove is provided inside the stabilizing slider, and a protective mechanism for damping and protecting the ink carriage from sudden stops is provided in the groove.

[0008] The protection mechanism includes a fixed sleeve fixedly assembled in the groove of the stabilizing slider, and a damping part is fixedly installed on both the left and right sides of the fixed sleeve, and an open groove is opened inside the damping part. An inertial impact component that moves by inertia is provided in the fixed sleeve, and the damping part is equipped with a plurality of adaptive damping components for damping protection. When the inertial impact component is moved by inertia, the adaptive damping component can be brought into contact with the stabilizing slider to perform damping protection.

[0009] As a further description of the above technical solution: through the synergistic effect of the inertial impact component and the adaptive damping component, a strong guarantee is provided for the stable operation of the ink carriage. When the ink carriage generates inertia due to an emergency stop, the inertial impact component responds quickly, and the impact ball moves quickly in the movable groove in the impact rod and hits the impact rod, causing the impact rod to move toward the damping part, thereby driving the damping rubber pad to come into contact with the stabilizing slide bar. The contact between the damping rubber pad and the stabilizing slide bar has a good damping and buffering effect, which can effectively absorb the energy generated by the inertia of the ink carriage and enhance the stability between the stabilizing slider and the stabilizing slide bar. At the same time, in this way, the problem of the ink carriage being prone to shaking and offsetting due to inertia is avoided, ensuring the stability of the ink carriage during high-speed reciprocating motion, thereby improving the precise positioning of the ink carriage on the printed pattern of the substrate, greatly improving the accuracy and consistency of inkjet, and simultaneously improving the printing quality.

[0010] Furthermore, a carrying and conveying assembly for carrying the printing substrate is fixedly assembled on the upper side of the machine base, and the carrying and conveying assembly includes a fixed base plate fixedly assembled on the upper side of the machine base, a fixed bracket is fixedly installed on the upper side of the fixed base plate, and a conveying motor is fixedly assembled on the fixed bracket, and a driving gear is fixedly connected to the upper side of the conveying motor using the output end, and the driving gear is connected to the driven gear through a transmission belt.

[0011] As a further description of the above technical solution: the output end of the conveying motor drives the driving gear to rotate, and the transmission action of the driving gear, the driven gear and the transmission belt drives the carrier plate and the printing substrate above the carrier plate to move synchronously, thereby realizing automatic feeding of the printing substrate and further improving its applicability.

[0012] Furthermore, the carrying and conveying assembly further comprises a connecting block fixedly mounted on the transmission belt, and a carrying plate for carrying the printing material is fixedly mounted on the upper side of the connecting block.

[0013] As a further description of the above technical solution: the provision of the connecting block facilitates the installation of the carrier plate, and the substrate to be printed is placed on the carrier plate carrying the conveying assembly, which facilitates the subsequent inkjet printing operation of the substrate.

[0014] Furthermore, the longitudinal movement mechanism includes a fixed seat fixedly assembled on the height adjustment mechanism, an adjustment motor is fixedly assembled on the outer side wall of the fixed seat, an output end of the adjustment motor passes through the fixed seat and is fixedly connected to a movable screw, and the movable screw is threadedly engaged with the moving seat;

[0015] Wherein, one side of the movable seat is fixedly connected to the stabilizing slider.

[0016] As a further description of the above technical solution: by adjusting the output end of the motor to drive the movable screw to rotate, under the action of the rotating force of the movable screw, the movable seat drives the ink carriage to move longitudinally, thereby driving the ink carriage to perform inkjet printing.

[0017] Furthermore, the inertial impact assembly includes an impact rod movably assembled in a fixed sleeve, a movable plate is fixedly installed on one side of the impact rod, and connecting springs are fixedly connected between the left and right sides of the movable plate and the inner wall of the fixed sleeve.

[0018] As a further description of the above technical solution: the provision of the impact rod is conducive to driving the adaptive damping assembly, and the provision of the connecting spring is conducive to resetting the impact rod.

[0019] Furthermore, a movable groove is provided inside the impact rod, and an impact ball is movably installed in the movable groove, and a sound-absorbing layer is laid on the inner wall of the movable groove.

[0020] As a further description of the above technical solution: when the movable seat drives the stable slider to move rapidly in one direction and suddenly stops due to printing needs, the inertial impact assembly responds quickly. Under the action of inertia, the impact ball moves rapidly in the movable groove in the impact rod and collides in the direction of the sudden stop, thereby generating an impact force on the impact rod, driving the impact rod to move toward the damping part, and the setting of the sound-absorbing layer can reduce the noise emitted when the impact ball contacts the impact rod.

[0021] Furthermore, the adaptive damping assembly includes a damping shell movably assembled on the inner wall of the damping part, a fixed bevel block is fixedly installed on the side of the damping shell facing the opening groove, a fixing ring is fixedly assembled on the outer wall of the damping shell, a fixing spring is fixedly connected between the fixing ring and the outer wall of the damping part, and a damping rubber pad is fixedly assembled on the side of the fixing ring away from the fixing spring.

[0022] As a further description of the above technical solution: the fixed ring is used to drive the damping rubber pad to make close contact with the stabilizing slide bar, thereby exerting its damping and buffering effect. Through this setting, not only the inertial impact energy generated by the sudden stop of the ink carriage is effectively absorbed, but also the stability between the stabilizing slider and the stabilizing slide bar is enhanced, ensuring the smooth operation of the ink carriage during the printing process.

[0023] Furthermore, the adaptive damping assembly further comprises a guide column movably mounted on the damping housing, one end of the guide column being movably mounted with a guide ball for guiding the movement of the stabilizing slide bar, one side of the guide ball being in contact with the stabilizing slide bar;

[0024] One end of the guide column extends to the interior of the damping shell and is fixedly connected to a first magnet block. A second magnet block is fixedly assembled on the inner wall of the damping shell. The opposite sides of the first magnet block and the second magnet block have the same magnetic properties, and there is a repulsive magnetic field force between the first magnet block and the second magnet block.

[0025] As a further description of the above technical solution: through the repulsive magnetic force of the first magnet block and the second magnet block, the guide ball on the guide column can be pushed to always be in contact with the outer wall of the stabilizing slide bar, thereby achieving adaptive abutment against the worn part of the outer wall of the stabilizing slide bar, effectively improving the moving stability of the ink carriage, and effectively avoiding the reduction of the moving stability of the ink carriage due to the wear of the outer wall of the stabilizing slide bar.

[0026] Furthermore, a mounting bracket is fixedly mounted on one side of the ink carriage, and a side of the mounting bracket away from the ink carriage is fixedly connected to the stabilizing slider.

[0027] As a further description of the above technical solution: this arrangement facilitates the assembly of the ink carriage and the longitudinal moving mechanism.

[0028] Furthermore, a control panel for operating the equipment is fixedly mounted on the base.

[0029] As a further description of the above technical solution: the setting of the control panel is conducive to the control of the device and further improves its applicability.

[0030] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0031] 1. The longitudinal moving device of the ink carriage of this inkjet printer provides a strong guarantee for the stable operation of the ink carriage through the synergistic effect of the inertial impact component and the adaptive damping component. When the ink carriage generates inertia due to an emergency stop, the inertial impact component responds quickly, and the impact ball moves quickly in the movable groove in the impact rod and hits the impact rod, causing the impact rod to move toward the damping part, thereby driving the damping rubber pad to contact the stabilizing slide bar. The contact between the damping rubber pad and the stabilizing slide bar has a good damping and buffering effect, which can effectively absorb the energy generated by the inertia of the ink carriage and enhance the stability between the stabilizing slider and the stabilizing slide bar. At the same time, in this way, the problem of shaking and offsetting of the ink carriage due to inertia is avoided, and the stability of the ink carriage during high-speed reciprocating motion is ensured, thereby improving the precise positioning of the ink carriage on the printed pattern of the substrate, greatly improving the accuracy and consistency of inkjet, and simultaneously improving the printing quality.

[0032] 2. The longitudinal movement of the ink carriage of this inkjet printer drives the guide ball to fit in contact with the stabilizing slide bar through the guide column in the adaptive damping assembly, which greatly improves the stability of the stabilizing slide bar sliding on the stabilizing slide bar. Through this fitting contact design, the stabilizing slide bar can maintain a good movement posture during the sliding process, reducing the shaking caused by uneven sliding. At the same time, the magnetic force of the first magnet block and the second magnet block repelling each other can push the guide ball on the guide column to always fit in closely with the outer wall of the stabilizing slide bar. Through this setting, adaptive contact can be achieved for the worn parts of the outer wall of the stabilizing slide bar. No matter where the outer wall of the stabilizing slide bar is worn, the guide ball can automatically adjust its position under the action of the magnetic force and fit closely with the worn part, effectively avoiding the problem of reduced stability of the ink carriage movement due to wear of the outer wall of the stabilizing slide bar, further significantly improving the stability of the ink carriage movement, and providing a solid foundation for accurate inkjet of the ink carriage.

[0033] 3. The longitudinal movement device of the ink carriage of this inkjet printer is set so that the inertia of the movement of the stabilizing slider is proportional to the damping force. The faster the stabilizing slider is when it stops suddenly, the greater the inertia generated and the farther the impact rod moves, so that the impact rod can trigger multiple adaptive damping components to make impact contact, driving multiple damping pads to come into contact with the stabilizing slider. This setting increases the contact area between the damping pads and the stabilizing slider, further enhancing the damping effect. When the ink carriage stops suddenly at high speed, multiple damping pads work simultaneously, which can more effectively absorb inertial energy and avoid deviation and shaking of the ink carriage, greatly improving the stability and reliability of the ink carriage under various working conditions, and further improving the effect and quality of inkjet printing.

Damping portions 62 are fixedly mounted on both the left and right sides of the fixed sleeve 61. The damping portions 62 have openings 621 formed therein. An inertial impact assembly 63 that moves inertially is disposed in the fixed sleeve 61. The damping portion 62 is equipped with a plurality of adaptive damping assemblies 64 for damping protection. The inertial impact assembly 63 is subjected to inertial movement, which enables the adaptive damping assemblies 64 to contact the stabilizing slider 51 for damping protection.

[0055] The coordinated action of the inertial impact assembly 63 and the adaptive damping assembly 64 provides a strong guarantee for the stable operation of the ink carriage 11. When the ink carriage 11 generates inertia due to an emergency stop, the inertial impact assembly 63 responds quickly, and the impact ball 635 moves quickly in the movable groove 634 in the impact rod 631 and hits the impact rod 631, causing the impact rod 631 to move toward the damping part 62, thereby driving the damping rubber pad 645 to contact the stabilizing slide bar 51. The contact between the damping rubber pad 645 and the stabilizing slide bar 51 has a good damping and buffering effect, which can effectively absorb the energy generated by the inertia of the ink carriage 11 and enhance the stability between the stabilizing slider 52 and the stabilizing slide bar 51. At the same time, in this way, the problem of the ink carriage 11 being prone to shaking and offset due to inertia is avoided, ensuring the stability of the ink carriage 11 during high-speed reciprocating motion, thereby improving the precise positioning of the ink carriage 11 on the printed pattern, greatly improving the accuracy and consistency of inkjet, and simultaneously improving the printing quality.

[0057] A mounting bracket 111 is fixedly mounted on one side of the ink carriage 11 , and a side of the mounting bracket 111 away from the ink carriage 11 is fixedly connected to the stabilizing slider 52 . This arrangement facilitates assembly of the ink carriage 11 and the longitudinal moving mechanism 40 .

[0058] A carrying and conveying assembly 20 for carrying the printing substrate is fixedly assembled on the upper side of the machine base 10. The carrying and conveying assembly 20 includes a fixed base plate 21 fixedly assembled on the upper side of the machine base 10, and a fixed bracket 22 is fixedly mounted on the upper side of the fixed base plate 21. A conveying motor 23 is fixedly assembled on the fixed bracket 22. The upper side of the conveying motor 23 is fixedly connected to a driving gear 24 using the output end, and the driving gear 24 is connected to a driven gear 26 through a transmission belt 25. The output end of the conveying motor 23 drives the driving gear 24 to rotate, and the transmission action of the driving gear 24, the driven gear 26 and the transmission belt 25 drive the carrying plate 28 and the printing substrate above the carrying plate 28 to move synchronously, thereby realizing automatic feeding of the printing substrate and further improving its applicability.

[0059] The carrying and conveying assembly 20 also includes a connecting block 27 fixedly mounted on the transmission belt 25, and a carrying plate 28 for carrying the printing material is fixedly mounted on the upper side of the connecting block 27; the setting of the connecting block 27 facilitates the installation of the carrying plate 28, and the substrate to be printed is placed on the carrying plate 28 of the carrying and conveying assembly 20, which facilitates the subsequent inkjet printing operation of the printing material.

[0060] The longitudinal moving mechanism 40 includes a fixed base 41 fixedly assembled on the height adjustment mechanism 30, and an adjusting motor 42 is fixedly assembled on the outer wall of the fixed base 41.

[0061] The inertial impact assembly 63 includes an impact rod 631 movably assembled in the fixed sleeve 61, a movable plate 632 is fixedly installed on one side of the impact rod 631, and connecting springs 633 are fixedly connected between the left and right sides of the movable plate 632 and the inner wall of the fixed sleeve 61; the setting of the impact rod 631 is conducive to driving the adaptive damping assembly 64, and the setting of the connecting spring 633 is conducive to resetting the impact rod 631.

[0062] A movable groove 634 is provided inside the impact rod 631, and an impact ball 635 is movably installed in the movable groove 634, and a sound-absorbing layer is laid on the inner wall of the movable groove 634; when the movable seat 44 drives the stable slider 52 to move rapidly in one direction and suddenly stops due to printing needs, the inertial impact component 63 responds quickly. Under the action of inertia, the impact ball 635 moves rapidly in the movable groove 634 in the impact rod 631 and collides in the direction of the sudden stop, thereby generating an impact force on the impact rod 631, driving the impact rod 631 to move toward the damping part 62, and the setting of the sound-absorbing layer can reduce the noise generated when the impact ball 635 contacts the impact rod 631.

[0063] The adaptive damping assembly 64 includes a damping shell 641 movably assembled on the inner wall of the damping part 62, a fixed bevel 642 is fixedly installed on the side of the damping shell 641 facing the opening groove 621, a fixing ring 643 is fixedly assembled on the outer wall of the damping shell 641, a fixing spring 644 is fixedly connected between the fixing ring 643 and the outer wall of the damping part 62, and a damping rubber pad 645 is fixedly assembled on the side of the fixing ring 643 away from the fixing spring 644; the fixing ring 643 is used to drive the damping rubber pad 645 to be in close contact with the stabilizing slide bar 51, thereby exerting its damping and buffering effect. Through this arrangement, not only the inertial impact energy generated by the sudden stop of the ink carriage 11 is effectively absorbed, but also the stability between the stabilizing slider 52 and the stabilizing slide bar 51 is enhanced, thereby ensuring the smooth operation of the ink carriage 11 during the printing process.

[0064] The adaptive damping assembly 64 also includes a guide post 646 movably mounted on the damping housing 641, one end of the guide post 646 is movably mounted with a guide ball 647 for guiding the movement of the stabilizing slide bar 51, and one side of the guide ball 647 is in contact with the stabilizing slide bar 51; one end of the guide post 646 extends to the interior of the damping housing 641 and is fixedly connected to a first magnet block 648, and a second magnet block 649 is fixedly mounted on the inner wall of the damping housing 641, and the opposite sides of the first magnet block 648 and the second magnet block 649 have the same magnetic properties, and there is a repulsive magnetic field force between the first magnet block 648 and the second magnet block 649; through the guide The column 646 drives the guide ball 647 to fit in contact with the outer wall of the stabilizing slide bar 51, thereby improving the sliding stability of the stabilizing slide bar 52; at the same time, through the repulsive magnetic force of the first magnet block 648 and the second magnet block 649, the guide ball 647 on the guide column 646 can be pushed to always fit in contact with the outer wall of the stabilizing slide bar 51, thereby realizing adaptive abutment against the worn part of the outer wall of the stabilizing slide bar 51. Even if there is wear on the outer wall of the stabilizing slide bar 51, the stable sliding effect can be maintained through adaptive abutment, which effectively improves the moving stability of the ink carriage 11 and effectively avoids the reduction of the moving stability of the ink carriage 11 due to wear on the outer wall of the stabilizing slide bar 51.

[0065] The specific usage and function of this embodiment are as follows:

[0066] Working principle: When in use, first place the substrate to be printed on the carrying plate 28 of the carrying conveying assembly 20, and fix the substrate in a fixed position. Then, the height of the ink carriage 11 is adjusted to the optimal position through the height adjustment mechanism 30, and then the adjustment motor 42 is started. The output end of the adjustment motor 42 drives the movable screw 43 to rotate. Under the action of the rotating force of the movable screw 43, the movable seat 44 is driven to drive the ink carriage 11 to move longitudinally, thereby driving the ink carriage 11 to perform inkjet printing. In the process of movement, the movable seat 44 will simultaneously drive the stabilizing slider 52 to slide stably on the stabilizing slide bar 51, thereby enhancing the stability of the movable seat 44 and the ink carriage 11 during movement, and effectively improving the accuracy and consistency of inkjet printing from the ink carriage 11.

[0067] During the process of inkjet printing on the substrate by the inking carriage 11, the output end of the conveying motor 23 drives the driving gear 24 to rotate. The driving gear 24, the driven gear 26 and the transmission belt 25 drive the carrier plate 28 and the substrate above the carrier plate 28 to move synchronously, thereby realizing automatic feeding of the substrate and further improving its applicability.

[0068] In addition, when the stabilizing slider 52 slides on the stabilizing slide bar 51, the adaptive damping assembly 64 plays a role, and the guide column 646 therein drives the guide ball 647 to fit in contact with the outer wall of the stabilizing slide bar 51, thereby improving the sliding stability of the stabilizing slider 52; at the same time, through the magnetic force of the first magnet block 648 and the second magnet block 649 repelling each other, the guide ball 647 on the guide column 646 can be pushed to always fit in contact with the outer wall of the stabilizing slide bar 51, so as to achieve adaptive abutment against the worn part of the outer wall of the stabilizing slide bar 51. Even if the outer wall of the stabilizing slide bar 51 is worn, the stable sliding effect can be maintained through the adaptive abutment, thereby effectively improving the movement stability of the ink carriage 11 and effectively avoiding the reduction of the movement stability of the ink carriage 11 due to the wear of the outer wall of the stabilizing slide bar 51;

[0069] Since the moving seat 44 drives the ink carriage 11 to move back and forth at high speed during the inkjet printing operation, when the moving seat 44 drives the stable slider 52 to move quickly in one direction and suddenly stops due to printing needs, the inertial impact component 63 responds quickly. Under the action of inertia, the impact ball 635 moves quickly in the movable groove 634 in the impact rod 631 and collides in the direction of the sudden stop, thereby generating an impact force on the impact rod 631, driving the impact rod 631 to move toward the damping part 62, and causing the end of the impact rod 631 to be inserted into the open groove 621 in the damping part 62; when the impact rod 631 moves in the open groove 621, it contacts the fixed inclined block 642 in the adaptive damping component 64, driving The damping inclined block pushes the damping housing 641 to move toward the stabilizing slide bar 51. During the movement, the damping housing 641 simultaneously drives the fixing ring 643 to move synchronously. The fixing ring 643 drives the damping rubber pad 645 to come into close contact with the stabilizing slide bar 51, thereby exerting its damping and buffering effect. This arrangement not only effectively absorbs the inertial impact energy generated by the sudden stop of the inking carriage 11, but also enhances the stability between the stabilizing slider 52 and the stabilizing slide bar 51, ensuring the smooth operation of the inking carriage 11 during the printing process, avoiding the possibility of shaking and deflection of the inking carriage 11 due to inertia, thereby improving the precise positioning of the inking carriage 11 on the printed pattern, improving the accuracy and consistency of inkjet, and simultaneously improving the printing quality.

[0070] In addition, the device makes the inertia of the movement of the stabilizing slider 52 proportional to the damping force. The faster the stabilizing slider 52 stops, the greater the inertia generated, and the farther the impact rod 631 moves. The impact rod 631 can trigger the damping rubber pads 645 on multiple adaptive damping components 64 to contact the stabilizing slider 51, thereby increasing the contact area with the stabilizing slider 51, further enhancing the damping effect, and effectively avoiding any deviation and shaking of the ink carriage 11 due to inertia, further improving the quality and stability of inkjet printing.
