Description

Technical Field

[0001] This utility model relates to the field of line printing machine technology, and in particular to a line printing machine that can be adjusted at multiple angles. Background Technology

[0002] Line printing machines are mainly used to accurately print lines, patterns, or text on the surface of various materials. They feature no need for plate making, flexible printing, rich colors, and strong adhesion. They are widely used in advertising production, decoration, industrial signage, and customized gifts. They can quickly meet personalized, small-batch, or large-batch printing needs, improving production efficiency and image quality.

[0003] Adjusting the front and rear position of the printhead frame on some equipment often relies on manually disassembling the track assembly or adjusting the machine base. The operation process is cumbersome. Taking the printing of thin and soft substrates such as paper money and thin canvas as an example, if it is necessary to switch the vertical printing area of ​​the substrate, the machine must be stopped first, the substrate clamping structure must be loosened, and then the printhead frame track must be moved manually to recalibrate the position before the work can continue. This is not only time-consuming, but also prone to misalignment of the printhead and the substrate due to manual operation errors, resulting in pattern misalignment.

[0004] Therefore, in order to address the existing problem of difficulty in adjusting the printing angle, a multi-angle adjustable inkjet printer is needed to solve the above problem. Utility Model Content

[0005] To address the problem of difficulty in adjusting the printing angle in existing technologies, this application provides a multi-angle adjustable inkjet printer. By adjusting the front and rear positions of the printhead frame and driving it to rotate left and right repeatedly, without disassembling the track or adjusting the base, it can quickly switch the printing area of ​​the substrate, reduce alignment deviation, and drive it to rotate left and right repeatedly without changing the clamps or tightening the bolts. It can adapt to non-planar substrates and multi-angle superimposed printing, reduce costs, and improve printing quality and efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-angle adjustable inkjet printer includes a base, a movable frame slidably connected to the inner wall of the base, a motor fixedly connected to the front end of the movable frame, and a printhead frame connected to the drive end of the motor via a movable component for adjusting the angle of the printhead frame. Movable frames are slidably connected to both sides of the inner wall of the base, and clamping components are provided on the inner walls of the movable frames for fixing banknotes of different sizes. An ink cartridge holder is fixedly connected to the top of the base, and a connecting hose is fixedly connected to the ink cartridge holder's outlet. The other end of the connecting hose is fixedly connected to the inner wall of the printhead frame.

[0008] As a further improvement of this utility model, the movable component includes a gear one fixedly connected to the front and rear ends of the nozzle frame. The outer wall of the gear one is meshed with a missing gear. The outer end of the gear one is rotatably connected to the inner wall of the movable frame. The front end of the missing gear on the front side is fixedly connected to the motor drive end.

[0009] As a further improvement of this utility model, a main bevel gear is fixedly connected to the inward end of each of the missing gears, and a secondary bevel gear is meshed with the outer wall of the main bevel gear. The top of the secondary bevel gear is rotatably connected to the inner wall of the movable frame.

[0010] As a further improvement of this utility model, a linear motor is fixedly connected to the inner wall of the base, and the outer wall of the linear motor is slidably connected to the inner wall of the movable frame.

[0011] As a further improvement of this utility model, the clamping assembly includes a connecting frame that is slidably connected to the inner wall of the movable frame, and a pressure plate is fixedly connected to the bottom end of the connecting frame.

[0012] As a further improvement of this utility model, a screw is rotatably connected to the inner wall of the connecting frame, and the outer wall of the screw is threadedly connected to the inner wall of the movable frame.

[0013] As a further improvement of this utility model, a knob is rotatably connected to the inner wall of the base, and a bidirectional threaded rod is fixedly connected to the rear end of the knob. Both sides of the outer wall of the bidirectional threaded rod are threaded to the inner wall of the movable frame.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. In this utility model, by adjusting the front and rear positions of the printhead frame and driving the printhead frame to rotate repeatedly left and right, without disassembling the track or adjusting the base, the substrate printing area can be quickly switched, reducing alignment deviation.

[0030] refer to Figure 1 , Figure 4 and Figure 5 As shown in Example 1: A multi-angle adjustable inkjet printer includes a base 1, a movable frame 3 slidably connected to the inner wall of the base 1, a motor 4 fixedly connected to the front end of the movable frame 3, gears 8 fixedly connected to both the front and rear ends of the printhead frame 9, and missing gears 5 meshing with the outer walls of the gears 8. The outward end of each gear 8 is rotatably connected to the inner wall of the movable frame 3. The front end of the missing gear 5 is fixedly connected to the drive end of the motor 4, and the inward end of each missing gear 5 is fixedly connected to a main bevel gear 6. The outer wall of the main bevel gear 6 meshes with a secondary bevel gear 7, and the top of the secondary bevel gear 7 is rotatably connected to the inner wall of the movable frame 3. A linear motor 2 is fixedly connected to the inner wall of the base 1, and the outer wall of the linear motor 2 is slidably connected to the inner wall of the movable frame 3 for adjusting the angle of the printhead frame 9.

[0031] Specifically, a water pump is installed in the ink cartridge holder 10 to extract ink from the ink cartridge and deliver it through a connecting hose 11. The length of the connecting hose 11 is sufficient for the printhead holder 9 to move. A controller is installed at the front end of the base 1. The controller is electrically connected to the linear motor 2, the electric motor 4, and the water pump inside the ink cartridge holder 10. The electric motor 4 can only drive the printhead holder 9 to rotate 60 degrees forward and backward. By adjusting the front and rear position of the printhead holder 9, it can drive the printhead holder 9 to rotate left and right repeatedly without disassembling the track or adjusting the base. It can quickly switch the substrate printing area, reduce alignment deviation, and drive it to rotate left and right repeatedly without changing the clamps or tightening the bolts. It can adapt to non-planar substrates and multi-angle superimposed printing, reduce costs, and improve printing quality and efficiency.

[0032] refer to Figure 2 and Figure 3 As shown in Embodiment 2: Movable frames 14 are slidably connected to both sides of the inner wall of the base 1. An ink cartridge holder 10 is fixedly connected to the top of the base 1. A connecting hose 11 is fixedly connected to the outlet of the ink cartridge holder 10. The other end of the connecting hose 11 is fixedly connected to the inner wall of the printhead holder 9. Connecting frames 16 are slidably connected to the inner wall of the movable frames 14. A pressure plate 17 is fixedly connected to the bottom of the connecting frames 16. A screw 15 is rotatably connected to the inner wall of the connecting frames 16. The outer wall of the screw 15 is threadedly connected to the inner wall of the movable frames 14. A knob 12 is rotatably connected to the inner wall of the base 1. A bidirectional threaded rod 13 is fixedly connected to the rear end of the knob 12. Both sides of the outer wall of the bidirectional threaded rod 13 are threadedly connected to the inner wall of the movable frames 14 for fixing banknotes of different sizes.

[0033] Specifically, the pressure plate 17 is made of rubber, the connecting hose 11 is a hose resistant to ink corrosion, and structural components such as the base 1, movable frame 3, movable bracket 14, and connecting bracket 16 are usually made of aluminum alloy, stainless steel, or engineering plastic. The gear 5, main bevel gear 6, secondary bevel gear 7, gear 8, screw 15, and bidirectional threaded rod 13 are made of steel or copper alloy, possessing wear resistance and strength. Through the movable pressure plates 17 on both sides, substrates of different lengths can be flexibly clamped without frequent clamp changes. It is suitable for thin and soft substrates such as paper and canvas or substrates of various specifications. The clamping force can be adjusted to avoid damaging the substrate and prevent displacement. It can also be adjusted in conjunction with the printhead frame 9 to reduce the time spent fixing the substrate and improve the efficiency of pre-printing preparation.

[0034] Working principle: First, place the banknote on the base 1 and turn the knob 12. The knob 12 drives the bidirectional threaded rod 13 to rotate, which in turn drives the movable frames 14 on both sides to slide inward, moving the pressure plates 17 on both sides of the banknote. Then, turn the screw 15, which drives the connecting frame 16 to move downward, thereby moving the pressure plates 17 downward to clamp the banknote on both sides. After fixing, the water pump in the ink cartridge holder 10 can be started to draw ink from the ink cartridge holder 10 and deliver it to the printhead holder 9 through the connecting hose 11 to print on the surface of the banknote. During printing, the linear motor 2 and the electric motor 4 can be controlled by the controller. The linear motor 2 drives the movable frame 3 and the printhead frame 9 to move back and forth. The motor 4 drives the front missing gear 5 to rotate. The missing gear 5 drives the rear main bevel gear 6 and the secondary bevel gear 7 to rotate, and synchronously drives the rear missing gear 5 to rotate in different directions. The missing gear 5 on one side will first rotate with the gear 8 and drive the printhead frame 9 to rotate. After rotating half a revolution, the missing gear 5 on one side will no longer mesh with the gear 8. At the same time, the missing gear 5 on the rear side will mesh with the gear 8 on the same side and drive the printhead frame 9 to rotate in different directions, thereby driving the printhead frame 9 to rotate left and right repeatedly to adjust the printing angle. After the printing is completed, the screw 15 is rotated in the opposite direction to contact the clamp on the money paper and take out the money paper.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
