Description

Technical Field

[0001] The present invention belongs to the technical field of inkjet printing, and particularly relates to a longitudinal movement device for an ink carriage of an inkjet printer. Background Art

[0002] As an efficient and precise printing mechanism without printing plates, inkjet printers have a wide range of applications in many fields such as graphic printing and packaging printing. Among them, the ink carriage, as one of the core components of an inkjet printer, is responsible for carrying the print head to move longitudinally above the printing medium to achieve continuous and uniform inkjet printing. The longitudinal movement device of the ink carriage not only requires precise positioning ability, which can drive the ink carriage to quickly and accurately switch between different positions in the printing area, ensuring that ink droplets can be accurately ejected 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 printing text, images or complex patterns, it is inseparable from the stable and precise longitudinal movement of the ink carriage.

[0003] However, the existing longitudinal movement devices for ink carriages of inkjet printers have many deficiencies in practical applications. During high-speed printing operations, the ink carriage needs to frequently perform sudden stop and sudden start operations during high-speed movement, and the sudden stop situation is relatively frequent. This drastic change in the movement state results in poor dynamic stability of the ink carriage. Especially when suddenly stopping during high-speed movement, 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 droplet position deviation and blurred lines in printed products, seriously reducing the printing quality; and frequent sudden stops and starts, as well as shaking and offset, will not only increase the mechanical wear of the ink carriage, shorten its service life, but also increase the maintenance cost and failure rate of the equipment; so there are deficiencies and cannot meet the user's usage requirements. Therefore, it is necessary to further improve.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies to provide a longitudinal movement device for an ink carriage of an inkjet printer, in order to achieve a more practical value purpose. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a longitudinal movement device for an ink carriage of an inkjet printer, which is achieved by the following specific technical means: A longitudinal movement device for an ink carriage of an inkjet printer includes a machine base and an ink carriage, a height adjustment mechanism provided on the machine base, a longitudinal movement mechanism provided on the height adjustment mechanism, and a stability component provided on the longitudinal movement mechanism; The stability component includes a stability slide bar and a stability slider. The stability slider is slidably installed on the stability slide bar. A groove is formed inside the stability slider, and a protection mechanism for damping protection of the sudden stop of the ink carriage is provided in the groove; The protection mechanism includes a fixed sleeve fixedly assembled in the groove of the stable slider. Damping parts are fixedly installed on both the left and right sides of the fixed sleeve, and an opening groove is formed inside the damping parts. An inertial impact component that moves under inertia is arranged in the fixed sleeve. The damping parts are equipped with a number of adaptive damping components for damping protection. When the inertial impact component moves under inertia, the adaptive damping components can be brought into contact with the stable slide bar for damping protection.

[0006] As a further description of the above technical solution: Through the synergistic effect of the inertial impact component and the adaptive damping component, it provides a strong guarantee for the stable operation of the ink carriage. When the ink carriage generates inertia due to sudden stop, the inertial impact component responds quickly. The impact ball moves rapidly in the moving groove of the impact rod and impacts the impact rod, causing the impact rod to move towards the damping part, and then driving the damping rubber pad to come into contact with the stable slide bar. The contact between the damping rubber pad and the stable slide bar has a good damping and buffering effect, which can effectively absorb the energy generated by the inertia of the ink carriage, enhance the stability between the stable slider and the stable slide bar. At the same time, in this way, the problem that the ink carriage is prone to shaking and offset due to inertia is avoided, ensuring the smoothness of the ink carriage during high-speed reciprocating movement, thereby improving the precise positioning of the printed pattern on the substrate by the ink carriage, greatly improving the accuracy and consistency of inkjet, and synchronously improving the printing quality.

[0007] Further, a loading and conveying component for printing and loading the substrate is fixedly assembled on the upper side of the machine base. The loading and conveying component includes a fixed bottom plate fixedly assembled on the upper side of the machine base. A fixed bracket is fixedly installed on the upper side of the fixed bottom plate. A conveying motor is fixedly assembled on the fixed bracket. The upper side of the conveying motor is fixedly connected to a driving gear by the output end. The driving gear is connected to a driven gear through a transmission belt.

[0008] As a further description of the above technical solution: The output end of the conveying motor drives the driving gear to rotate. Through the transmission of the driving gear, the driven gear and the transmission belt, the loading plate and the substrate above the loading plate are driven to move synchronously, realizing the automatic feeding of the substrate and further improving its applicability.

[0009] Further, the loading and conveying component further includes a connecting block fixedly assembled on the transmission belt. A loading plate for loading the substrate is fixedly installed on the upper side of the connecting block.

[0010] As a further description of the above technical solution: The setting of the connecting block is beneficial to the installation of the loading plate, and the substrate to be printed is placed on the loading plate of the loading and conveying component, facilitating the subsequent inkjet printing operation of the substrate.

[0011] Further, 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. The output end of the adjustment motor passes through the fixed seat and is fixedly connected with a movable screw rod. A movable seat is screwed on the movable screw rod. Wherein, one side of the movable seat is fixedly connected with a stable slider.

[0012] As a further description of the above technical solution: The output end of the adjustment motor drives the movable screw rod to rotate. Under the action of the rotational force of the movable screw rod, the movable seat is driven to drive the ink carriage to move longitudinally, thereby driving the ink carriage to perform inkjet printing.

[0013] Further, the inertial impact component includes an impact rod movably assembled in a fixed sleeve. A movable plate is fixedly installed on one side of the impact rod. Connecting springs are fixedly connected between the left and right sides of the movable plate and the inner wall of the fixed sleeve.

[0014] As a further description of the above technical solution: The setting of the impact rod is beneficial to driving the adaptive damping component, and the setting of the connecting spring is beneficial to the reset of the impact rod.

[0015] Further, a movable groove is formed inside the impact rod, and an impact ball is movably installed in the movable groove. A sound-absorbing layer is laid on the inner wall of the movable groove.

[0016] 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 requirements, the inertial impact component responds quickly. Under the action of inertia, the impact ball moves rapidly in the movable groove of the impact rod and impacts in the direction of sudden stop, thereby generating an impact force on the impact rod, driving the impact rod to move towards the damping part, and the setting of the sound-absorbing layer can reduce the noise generated when the impact ball contacts the impact rod.

[0017] Further, the adaptive damping component includes a damping housing movably assembled on the inner wall of the damping part. A fixed inclined block is fixedly installed on the side of the damping housing facing the opening groove. A fixed ring is fixedly assembled on the outer wall of the damping housing. A fixed spring is fixedly connected between the fixed ring and the outer wall of the damping part. A damping rubber pad is fixedly assembled on the side of the fixed ring away from the fixed spring.

[0018] As a further description of the above technical solution: The fixed ring is used to drive the damping rubber pad to be in close contact with the stable slide rod, 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 stable slider and the stable slide rod is enhanced, ensuring the smooth operation of the ink carriage during printing.

[0019] Further, the adaptive damping assembly further includes a guiding column movably assembled on the damping housing. One end of the guiding column is movably assembled with a guiding ball for guiding the movement of the stable sliding rod, and one side of the guiding ball is in fitting contact with the stable sliding rod. One end of the guiding column extends into the interior of the damping housing and is fixedly connected with a first magnet block. A second magnet block is fixedly assembled on the inner wall of the damping housing. The opposite surfaces of the first magnet block and the second magnet block have the same magnetic property, and there is a repulsive magnetic field force between the first magnet block and the second magnet block.

[0020] As a further description of the above technical solution: Through the repulsive magnetic force between the first magnet block and the second magnet block, the guiding ball on the guiding column can be pushed to always be in fitting contact with the outer wall of the stable sliding rod, realizing adaptive abutment against the worn part of the outer wall of the stable sliding rod, effectively improving the moving stability of the ink carriage, and effectively avoiding the reduction of the moving stability of the ink carriage caused by the wear of the outer wall of the stable sliding rod.

[0021] Further, an installation frame is fixedly installed on one side of the ink carriage, and the stable slider is fixedly connected to the side of the installation frame away from the ink carriage.

[0022] As a further description of the above technical solution: This setting is beneficial to the assembly of the ink carriage and the longitudinal moving mechanism.

[0023] Further, a control panel for controlling the equipment is fixedly assembled on the machine base.

[0024] As a further description of the above technical solution: The setting of the control panel is beneficial to controlling the equipment and further improving its applicability.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: 1. The longitudinal movement 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 inertia impact assembly and the adaptive damping assembly. When the ink carriage generates inertia due to sudden stop, the inertia impact assembly responds quickly. The impact ball quickly moves in the movable groove of the impact rod and impacts the impact rod, causing the impact rod to move towards the damping part, thereby driving the damping rubber pad to come into contact with the stable sliding rod. The contact between the damping rubber pad and the stable sliding rod has a good damping and buffering effect, which can effectively absorb the energy generated by the inertia of the ink carriage, enhance the stability between the stable slider and the stable sliding rod. At the same time, in this way, the problem that the ink carriage is prone to shaking and offset due to inertia is avoided, ensuring the smoothness of the ink carriage during high-speed reciprocating movement, thereby improving the accurate positioning of the printed pattern on the printing substrate by the ink carriage, greatly improving the accuracy and consistency of inkjet, and synchronously improving the printing quality.

[0026] 2. The longitudinal movement of the ink carriage of this inkjet printer is driven by the guide column in the adaptive damping component to drive the guide ball to fit and contact with the stable slide rod, greatly improving the stability of the stable slider sliding on the stable slide rod. Through this fitting contact design, the stable slider can maintain a good motion posture during the sliding process, reducing the shaking caused by unsmooth sliding. At the same time, the repulsive magnetic force between the first magnet block and the second magnet block can push the guide ball on the guide column to always fit and contact tightly with the outer wall of the stable slide rod. Through this setting, it can realize the adaptive abutment against the worn part of the outer wall of the stable slide rod. No matter where the outer wall of the stable slide rod is worn, the guide ball can automatically adjust its position under the action of magnetic force and fit tightly with the worn part, effectively avoiding the problem of reduced stability of the ink carriage movement caused by the wear of the outer wall of the stable slide rod, and further significantly improving the stability of the ink carriage movement, providing a solid foundation for the accurate inkjet of the ink carriage.

[0027] 3. The longitudinal movement device of the ink carriage of this inkjet printer sets the inertia of the stable slider to be proportional to the damping force. When the stable slider stops suddenly at a faster speed, the greater the inertia generated, the farther the impact rod moves. Thus, the impact rod can trigger multiple adaptive damping components for impact contact, driving multiple damping rubber pads to contact with the stable slide rod. Through this setting, the contact area between the damping rubber pads and the stable slide rod is increased, further strengthening the damping effect. In the case of the ink carriage stopping suddenly at high speed, multiple damping rubber pads work simultaneously, which can more effectively absorb the inertial energy, avoid the ink carriage from shifting and shaking, greatly improving the stability and reliability of the ink carriage under various working conditions, and further enhancing the effect and quality of inkjet printing.

By the inertial movement of the inertial impact component 63, the adaptive damping component 64 can be brought into contact with the stability slide bar 51 for damping protection; Through the synergistic effect of the inertial impact component 63 and the adaptive damping component 64, it 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 component 63 responds quickly, and the impact ball 635 moves rapidly in the movable slot 634 of the impact rod 631 and impacts the impact rod 631, causing the impact rod 631 to move towards the damping part 62, thereby driving the damping rubber pad 645 to come into contact with the stability slide bar 51. The contact between the damping rubber pad 645 and the stability slide bar 51 plays a good damping and buffering effect, which can effectively absorb the energy generated by the inertia of the ink carriage 11, enhance the stability between the stability slider 52 and the stability slide bar 51. At the same time, in this way, the problem that the ink carriage 11 is prone to shaking and offset due to inertia is avoided, ensuring the smoothness of the ink carriage 11 during high-speed reciprocating movement, thereby improving the precise positioning of the printed pattern on the substrate by the ink carriage 11, greatly improving the accuracy and consistency of inkjet, and synchronously improving the printing quality.

[0033] A control panel 12 for controlling the equipment is fixedly assembled on the machine base 10; the setting of the control panel 12 is beneficial for controlling the equipment and further improving its applicability.

[0034] An installation frame 111 is fixedly installed on one side of the ink carriage 11, and the side of the installation frame 111 away from the ink carriage 11 is fixedly connected to the stability slider 52; this setting is beneficial for the assembly of the ink carriage 11 and the longitudinal movement mechanism 40.

[0035] On the upper side of the machine base 10, a loading and conveying assembly 20 for printing and carrying the printing substrate is fixedly assembled. The loading and conveying assembly 20 includes a fixed bottom plate 21 fixedly assembled on the upper side of the machine base 10. On the upper side of the fixed bottom plate 21, a fixed bracket 22 is fixedly installed. On the fixed bracket 22, a conveying motor 23 is fixedly assembled. On the upper side of the conveying motor 23, a driving gear 24 is fixedly connected by means of an output end. The driving gear 24 is drivingly connected to a driven gear 26 through a transmission belt 25. By driving the driving gear 24 to rotate through the output end of the conveying motor 23, and through the driving action of the driving gear 24, the driven gear 26 and the transmission belt 25, the loading plate 28 and the printing substrate above the loading plate 28 are driven to move synchronously, realizing the automatic feeding of the printing substrate and further improving its applicability.

[0036] The loading and conveying assembly 20 further includes a connecting block 27 fixedly assembled on the transmission belt 25. On the upper side of the connecting block 27, a loading plate 28 for carrying the printing substrate is fixedly installed. The arrangement of the connecting block 27 is beneficial to the installation of the loading plate 28, and the printing substrate to be printed is placed on the loading plate 28 of the loading and conveying assembly 20, facilitating the subsequent inkjet printing operation of the printing substrate.

[0037] The longitudinal movement mechanism 40 includes a fixed seat 41 fixedly assembled on the height adjustment mechanism 30. On the outer side wall of the fixed seat 41, an adjustment motor 42 is fixedly assembled. The output end of the adjustment motor 42 passes through the fixed seat 41 and is fixedly connected to a movable screw rod 43. A movable seat 44 is threadedly engaged with the movable screw rod 43. Among them, one side of the movable seat 44 is fixedly connected to a stable slider 52. By driving the movable screw rod 43 to rotate through the output end of the adjustment motor 42, under the action of the rotational force of the movable screw rod 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.

[0038] The inertial impact assembly 63 includes an impact rod 631 movably assembled in a fixed sleeve 61. On one side of the impact rod 631, a movable plate 632 is fixedly installed. Between the left and right sides of the movable plate 632 and the inner wall of the fixed sleeve 61, connecting springs 633 are fixedly connected. The arrangement of the impact rod 631 is beneficial to driving the adaptive damping assembly 64, and the arrangement of the connecting springs 633 is beneficial to the reset of the impact rod 631.

[0039] The interior of the impact rod 631 is provided with a movable slot 634, and an impact ball 635 is movably installed in the movable slot 634. A sound-absorbing layer is laid on the inner wall of the movable slot 634. When the moving seat 44 drives the stable slider 52 to move rapidly in one direction and suddenly stops due to printing requirements, the inertial impact assembly 63 responds quickly. Under the action of inertia, the impact ball 635 moves rapidly in the movable slot 634 of the impact rod 631 and impacts in the direction of sudden stop, thereby generating an impact force on the impact rod 631, driving the impact rod 631 to move towards the damping portion 62, and the noise generated when the impact ball 635 contacts the impact rod 631 can be reduced through the setting of the sound-absorbing layer.

[0040] The adaptive damping assembly 64 includes a damping housing 641 movably assembled on the inner wall of the damping portion 62. A fixed inclined block 642 is fixedly installed on one side of the damping housing 641 facing the opening slot 621. A fixed ring 643 is fixedly assembled on the outer wall of the damping housing 641. A fixed spring 644 is fixedly connected between the fixed ring 643 and the outer wall of the damping portion 62. A damping rubber pad 645 is fixedly assembled on one side of the fixed ring 643 away from the fixed spring 644. The fixed ring 643 is used to drive the damping rubber pad 645 to be in close contact with the stable slide rod 51, thereby exerting its damping and buffering effect. Through this setting, not only the inertial impact energy generated by the ink carriage 11 due to sudden stop is effectively absorbed, but also the stability between the stable slider 52 and the stable slide rod 51 is enhanced, ensuring the smooth operation of the ink carriage 11 during the printing process.

[0041] The adaptive damping assembly 64 further includes a guiding column 646 movably assembled on the damping housing 641. One end of the guiding column 646 is movably assembled with a guiding ball 647 for guiding the movement of the stable slide rod 51. One side of the guiding ball 647 is in fitting contact with the stable slide rod 51. One end of the guiding column 646 extends into the interior of the damping housing 641 and is fixedly connected with a first magnet block 648. A second magnet block 649 is fixedly assembled on the inner wall of the damping housing 641. The opposite surfaces of the first magnet block 648 and the second magnet block 649 have the same magnetic property, and there is a repulsive magnetic force between the first magnet block 648 and the second magnet block 649. By driving the guiding ball 647 on the guiding column 646 to be in fitting contact with the outer wall of the stable slide rod 51, the stability of the sliding of the stable slider 52 is improved. At the same time, through the repulsive magnetic force between the first magnet block 648 and the second magnet block 649, the guiding ball 647 on the guiding column 646 can be pushed to always be in fitting contact with the outer wall of the stable slide rod 51, realizing adaptive abutment against the worn part of the outer wall of the stable slide rod 51. Even if there is wear on the outer wall of the stable slide rod 51, a stable sliding effect can be maintained through adaptive abutment, effectively improving the moving stability of the ink carriage 11 and effectively avoiding the reduction of the moving stability of the ink carriage 11 caused by the wear of the outer wall of the stable slide rod 51.

[0042] The specific usage mode and function of this embodiment: Working principle: During use, first place the object to be printed on the carrier plate 28 of the carrier conveying assembly 20 and fix and limit the object to be printed. Subsequently, adjust the height of the ink carriage 11 through the height adjustment mechanism 30 to make it reach the optimal position. Then, start the adjustment motor 42. The output end of the adjustment motor 42 drives the movable screw 43 to rotate. Under the action of the rotational 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. Moreover, during the movement of the movable seat 44, the stable slider 52 will be driven to stably slide on the stable slide bar 51, thereby enhancing the stability of the movable seat 44 and the ink carriage 11 during movement, effectively improving the accuracy and consistency of the inkjet of the ink carriage 11; During the process of the ink carriage 11 performing inkjet printing on the object to be printed, at the same time, the output end of the conveying motor 23 drives the driving gear 24 to rotate. Through the transmission of the driving gear 24, the driven gear 26, and the transmission belt 25, the carrier plate 28 and the object to be printed above the carrier plate 28 are driven to move synchronously, realizing the automatic feeding of the object to be printed and further enhancing its applicability; In addition, when the stable slider 52 slides on the stable slide bar 51, the adaptive damping assembly 64 plays a role. The guide post 646 therein drives the guide ball 647 to be in close contact with the outer wall of the stable slide bar 51, thereby improving the stability of the sliding of the stable slider 52; at the same time, through the repulsive magnetic force between the first magnet block 648 and the second magnet block 649, the guide ball 647 on the guide post 646 can be pushed to always be in close contact with the outer wall of the stable slide bar 51, realizing the adaptive abutment against the worn part of the outer wall of the stable slide bar 51. Even if there is wear on the outer wall of the stable slide bar 51, the stable sliding effect can be maintained through the adaptive abutment, effectively enhancing the movement stability of the ink carriage 11 and effectively avoiding the reduction of the movement stability of the ink carriage 11 caused by the wear of the outer wall of the stable slide bar 51; Since the moving base 44 drives the ink carriage 11 to run reciprocally at a high speed during the inkjet printing moving operation, when the moving base 44 drives the stabilizing slider 52 to move rapidly in one direction and suddenly stops urgently due to printing requirements, the inertia impact assembly 63 responds quickly. Under the action of inertia, the impact ball 635 moves rapidly in the moving slot 634 of the impact rod 631 and impacts in the direction of the sudden stop, thereby generating an impact force on the impact rod 631, driving the impact rod 631 to move towards the damping portion 62, and inserting the end of the impact rod 631 into the opening slot 621 in the damping portion 62; when the impact rod 631 moves in the opening slot 621, it contacts the fixed inclined block 642 in the adaptive damping assembly 64, driving the damping inclined block to push the damping housing 641 to move towards the stabilizing slide bar 51. The damping housing 641 drives the fixed ring 643 to move synchronously during the movement, and the fixed ring 643 drives 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 setting, 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, ensuring the smooth operation of the ink carriage 11 during printing, avoiding the possibility of the ink carriage 11 shaking and shifting due to inertia, thereby improving the precise positioning of the printed pattern on the substrate by the ink carriage 11, enhancing the accuracy and consistency of inkjet, and simultaneously improving the printing quality; In addition, the device is set such that the inertia of the movement of the stabilizing slider 52 is proportional to the damping force. When the stabilizing slider 52 stops suddenly at a faster speed, the greater the inertia generated, the farther the impact rod 631 moves. The impact rod 631 can trigger the damping rubber pads 645 on multiple adaptive damping assemblies 64 to contact the stabilizing slide bar 51, thereby increasing the contact area with the stabilizing slide bar 51, further strengthening the damping effect, and effectively avoiding any offset and shaking of the ink carriage 11 due to inertia, further improving the quality and stability of inkjet printing.
