Description

Technical Field

[0001] This utility model belongs to the field of printer technology, and more specifically, it relates to a drawer-type printing structure for an industrial inkjet printer. Background Technology

[0002] Existing single-pass industrial inkjet printers operate on the principle of a stationary printhead while the printing material moves at high speed. This method is primarily used in printing applications with very high material throughput requirements. In this inkjet printing method, the printhead remains stationary. When the printhead needs cleaning, the cleaning device must be placed below it. Due to space constraints, traditional single-pass inkjet printers often have the cleaning device positioned before or after the printhead module. When cleaning is required, the printhead module is raised, and the cleaning device slides underneath to perform the cleaning action.

[0003] The existing publication number CN216733544U discloses a drawer-type inkjet printer structure and printer for industrial inkjet printers. By setting a drawer-type printhead mounting plate, it improves the space utilization of the equipment and saves space. On the other hand, it is convenient and simple to operate, improves the rationality of printhead maintenance of single-channel inkjet printers, and improves maintenance efficiency. Moreover, this structure is applicable to the structure of most single-channel inkjet printers, and has good versatility.

[0004] Based on the above, the following problems were found: However, when the printer is in use, since the printhead mounting plate is connected to the extension plate by relying solely on the connecting block on one side, after a long period of use, due to the weight of the printhead mounting plate itself and the weight of the printhead, the end of the printhead mounting plate away from the connecting block is prone to shifting downwards, causing deviations in the horizontality of the subsequent printheads. At the same time, the limiting mechanism of the mounting plate is located inside the printer, and when it is necessary to pull it out, it is necessary to enter the inside to release the limiting mechanism, which is inconvenient to use.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a drawer-type printing structure for industrial inkjet printers, in order to achieve a more practical value. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a drawer-type printing structure for an industrial inkjet printer, which solves the problem that the end of the printhead mounting plate furthest from the connecting block tends to shift downwards after prolonged use, leading to deviations in the horizontal alignment of subsequent printheads.

[0007] This utility model provides a drawer-type printing structure for an industrial inkjet printer, achieved through the following specific technical means:

[0008] An industrial inkjet printer drawer-type printing structure includes a base, with support columns fixed at both ends on one side of the top of the base. A first connecting plate is slidably connected to one side of the support columns. Second connecting plates are fixed to both sides of the middle part of one side of the first connecting plate. Guide rails are fixed to opposite sides of the two second connecting plates. Slider blocks are slidably connected to the outer walls of the two guide rails. Printhead mounting plates are fixed to the bottom of the two sliders. A second connecting block is fixed to the top of one side of the printhead mounting plate. A telescopic rod is fixed to one side of the second connecting block. A through hole is formed inside the second connecting plate.

[0009] Furthermore, the through hole and the telescopic rod are movably connected, and the depth of the through hole is greater than the length of the telescopic rod.

[0010] Furthermore, a limit rod is fixed on one side of the guide rail, and a lever is fixed at one end of the limit rod. The lever and the limit rod are arranged at an angle.

[0011] Furthermore, the limiting rod is L-shaped, and a limiting block is fixed to the top of the guide rail. The limiting block is used in conjunction with the protruding end of the limiting rod.

[0012] Furthermore, a third connecting block is fixed to one side of the slider. The third connecting block is L-shaped, and a connecting bolt is threaded through the top of the third connecting block. The connecting bolt is connected to the nozzle mounting plate.

[0013] Furthermore, a stepper motor is fixed to one side of one of the support columns, and a threaded rod is fixed to the power end of the stepper motor. Moving blocks are threadedly connected to both sides of the middle part of the outer wall of the threaded rod, and the threads of the two moving blocks are in opposite directions.

[0014] Furthermore, each of the two movable blocks is hinged to a connecting rod at its top, and a first connecting block is fixed to the bottom of the middle part of one side of the first connecting plate, with the tops of the two connecting rods hinged to the first connecting block.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, one side of the nozzle mounting plate is connected to the second connecting plate via a third connecting block, and the other side is connected via a telescopic rod and a through hole. At the same time, the third connecting block can move together with the slider, and the telescopic rod slides in the through hole, making the connection more stable without affecting the pulling of the nozzle mounting plate, thereby improving the long-term connection stability of the nozzle mounting plate.

[0017] 2. In normal use, the slider can remain stationary at one end of the guide rail by pressing the protruding end of the limiting rod against the limiting block. When it is necessary to pull out the nozzle mounting plate, the two levers can be moved towards the center to release the limiting rod and the limiting block, thus achieving a very convenient effect of releasing the limit.

[0018] 3. In this utility model, by controlling the stepper motor to drive the threaded rod to rotate, two moving blocks can be driven to move horizontally on the threaded rod. When the two moving blocks move closer to the center, the included angle at the top of the connecting rod becomes smaller, and the first connecting block and the first connecting plate move upward. Conversely, they move downward, thereby achieving the effect of quickly controlling the height of the nozzle mounting plate and having a self-locking function. Attached Figure Description

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 4 As shown:

[0029] This utility model provides a drawer-type printing structure for an industrial inkjet printer, including a base 1. Support columns 2 are fixed at both ends of one side of the top of the base 1. A first connecting plate 8 is slidably connected to one side of the support column 2. A second connecting plate 9 is fixed to both sides of the middle part of one side of the first connecting plate 8. Guide rails 11 are fixed to opposite sides of the two second connecting plates 9. Sliding sliders 17 are slidably connected to the outer walls of the two guide rails 11. A printhead mounting plate 10 is fixed to the bottom of the two sliders 17. A second connecting block 12 is fixed to the top of one side of the printhead mounting plate 10. A telescopic rod 13 is fixed to one side of the second connecting block 12. A through hole 91 is opened through the interior of the second connecting plate 9.

[0030] The through hole 91 and the telescopic rod 13 are movably connected, and the depth of the through hole 91 is greater than the length of the telescopic rod 13. One side of the nozzle mounting plate 10 is connected to the second connecting plate 9 through the third connecting block 18, and the other side is connected to the through hole 91 through the telescopic rod 13. At the same time, the third connecting block 18 can move together with the slider 17, and the telescopic rod 13 slides in the through hole 91, making the connection more stable and not affecting the pulling of the nozzle mounting plate 10.

[0031] Among them, a limit rod 16 is fixed on one side of the guide rail 11, and a lever 14 is fixed on one end of the limit rod 16. The lever 14 and the limit rod 16 are set at an angle. The limit rod 16 is made of elastic steel and has a certain elasticity. When the lever 14 is moved, the limit rod 16 can deform.

[0032] The limiting rod 16 is L-shaped, and the top of the guide rail 11 is fixed with a limiting block 15. The limiting block 15 is used in conjunction with the protruding end of the limiting rod 16. By pressing the protruding end of the limiting rod 16 against the limiting block 15, the slider 17 can remain stationary at one end of the guide rail 11. When it is necessary to pull out the nozzle mounting plate 10, the two levers 14 can be moved towards the middle to release the limiting rod 16 and the limiting block 15.

[0033] The slider 17 has a third connecting block 18 fixed on one side. The third connecting block 18 is L-shaped and has a connecting bolt 19 threaded through the top of the third connecting block 18. The connecting bolt 19 is connected to the nozzle mounting plate 10. By using the third connecting block 18 and the connecting bolt 19 to connect one side of the nozzle mounting plate 10 to the slider 17, the connecting bolt 19 can be unscrewed directly when the nozzle mounting plate 10 needs to be disassembled.

[0034] One of the support columns 2 has a stepper motor 3 fixed on one side. The power end of the stepper motor 3 is fixed with a threaded rod 4. The two moving blocks 5 are threadedly connected to the middle of the outer wall of the threaded rod 4. The two moving blocks 5 have opposite thread directions. By driving the threaded rod 4 to rotate through the stepper motor 3, the two moving blocks 5 can be driven to move horizontally on the threaded rod 4. The two moving blocks 5 with opposite threads can move to both ends at the same time or move towards the middle at the same time.

[0035] The tops of the two movable blocks 5 are hinged with connecting rods 6, and the bottom of the middle part of the first connecting plate 8 is fixed with a first connecting block 7. The tops of the two connecting rods 6 are hinged with the first connecting block 7. When the two movable blocks 5 move closer to the middle, the included angle of the tops of the connecting rods 6 becomes smaller, and the first connecting block 7 and the first connecting plate 8 move upward. Conversely, they move downward.

[0036] The specific usage and function of this embodiment are as follows:

[0037] In this invention, when it is necessary to control the horizontal height of the nozzle mounting plate 10, the stepper motor 3 drives the threaded rod 4 to rotate, which in turn drives the two moving blocks 5 to move horizontally on the threaded rod 4. Conversely, the two moving blocks 5 can move simultaneously to both ends or simultaneously move towards the middle. When the two moving blocks 5 move towards the middle, the included angle at the top of the connecting rod 6 becomes smaller, and the first connecting block 7 and the first connecting plate 8 move upward. Conversely, they move downward. After adjustment, the servo motor 3 can be stopped. The servo motor 3 has a self-locking function. During normal use, the slider 17 can remain stationary at one end of the guide rail 11 by pressing the protruding end of the limiting rod 16 against the limiting block 15. When it is necessary to pull the nozzle mounting plate 10, the limiting rod 16 is made of elastic steel and has a certain degree of elasticity. When the lever 14 is turned, the limiting rod 16 can deform. The two levers 14 can be turned towards the middle to release the limiting rod 16 and the limiting block 15.
