Description

Technical Field

[0001] This utility model relates to the field of electrohydraulic inkjet printing devices, specifically an electrohydraulic inkjet printing device with a ring electrode constraining the jet. Background Technology

[0002] Electrohydraulic inkjet printing, as a high-precision material deposition technology, plays a vital role in modern manufacturing. However, existing electrohydraulic inkjet printing devices face numerous unresolved problems in practical applications.

[0003] In terms of jet control, traditional electro-hydraulic inkjet printing devices lack effective jet confinement methods. During flight, the jet ejected from the printhead is highly susceptible to external airflow disturbances and uneven electric fields, leading to unstable jet trajectories and severe divergence. This makes it difficult to guarantee the accuracy of the printed pattern, seriously affecting production efficiency and product quality. Furthermore, regarding the electrode structure, existing inkjet printing devices mostly use fixed electrodes, making disassembly and replacement difficult once damaged or when electrode parameters need to be adjusted according to different processes. Moreover, the connection between the inkjet printing device and the robotic arm typically employs complex bolting or welding methods, resulting in cumbersome installation and disassembly processes that consume significant manpower and time. Therefore, it is necessary to design an electro-hydraulic inkjet printing device with ring electrodes to confine the jet and solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a current fluid inkjet printing device with a ring electrode constraining the jet, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hydrostatic printing device with annular electrode constraining the jet, comprising a guide frame, a nozzle connected to the surface of the guide frame, an annular slide plate fixedly mounted on the surface of the guide frame, a slider slidably connected inside the annular slide plate, and a plurality of sliders arranged in an annular pattern, a traction rod fixedly mounted on the surface of the slider, the front end of the traction rod penetrating the annular slide plate and extending to the outside of the annular slide plate, an annular electrode for cooperating with the nozzle fixedly mounted on the front end of the traction rod, and a plurality of movable openings for cooperating with the sliders arranged in an annular pattern on the surface of the annular slide plate.

[0006] Preferably, a U-shaped plate is slidably connected to the surface of the guide frame, and a stop plate is fixedly installed between the two sides of the inner wall of the U-shaped plate. Limiting grooves for use with traction rods are opened on both sides of the bottom of the stop plate. A pressure plate is rotatably connected to the top of the guide frame through a bearing component, and the bottom of the pressure plate is in close contact with the top of the stop plate.

[0007] Preferably, a mounting base is fixedly installed at the rear of the guide frame, and a robotic arm connecting rod is slidably connected inside the mounting base. A tube is fixedly installed at the bottom of the U-shaped plate, and the bottom end of the tube passes through the mounting base and the robotic arm connecting rod in sequence and extends into the interior of the robotic arm connecting rod.

[0008] Preferably, a spring is welded to the bottom of the inner cavity of the insert, and a sliding rod is welded to the top of the spring. The top of the sliding rod passes through the pressure plate and extends to the outside of the pressure plate.

[0009] Preferably, a limiting opening is provided on the rear side of the top of the pressure plate to cooperate with the slide rod.

[0010] Preferably, the bottom of the guide frame is connected to a feed pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This annular electrode constrains the jet flow of the electro-hydraulic printing device. By setting the annular electrode, the jet flow of the nozzle can be constrained. When it is necessary to remove the annular electrode, the pressure plate can be rotated to disengage from the backing plate. Then, the backing plate is pulled upward. After the backing plate rises, the annular electrode can be rotated clockwise. The rotation of the annular electrode drives the traction rod to rotate, which in turn drives the slider to rotate. After the slider rotates to the last side of the movable opening, the annular electrode can be pulled forward to disengage the slider from the annular slide plate, thereby facilitating the removal and replacement of the annular electrode.

[0013] 2. The annular electrode constrained jet electro-hydraulic inkjet printing device inserts the robotic arm connecting rod into the mounting base, then presses down the U-shaped plate. After the U-shaped plate descends, the insert can pass through the mounting base and be inserted into the robotic arm connecting rod. Then, the pressure plate is rotated, so that the sliding rod passes through the pressure plate and limits the pressure plate through the limiting port, thereby facilitating the docking and disassembly of the guide frame and the robotic arm connecting rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to Figure 1-6 As shown, this utility model provides an electrohydraulic inkjet printing device with a ring electrode constraining the jet, including a guide frame 1, a nozzle 2 connected to the surface of the guide frame 1, an annular slide plate 3 fixedly installed on the surface of the guide frame 1, a slider 4 slidably connected inside the annular slide plate 3, and several sliders 4 arranged in a ring, a traction rod 5 fixedly installed on the surface of the slider 4, the front end of the traction rod 5 passing through the annular slide plate 3 and extending to the outside of the annular slide plate 3, an annular electrode 6 for cooperating with the nozzle 2 fixedly installed at the front end of the traction rod 5, and several movable openings 18 for cooperating with the sliders 4 on the surface of the annular slide plate 3, arranged in a ring.

[0023] Specifically, a U-shaped plate 7 is slidably connected to the surface of the guide frame 1. A stop plate 8 is fixedly installed between the two sides of the inner wall of the U-shaped plate 7. Limiting grooves 9 are opened on both sides of the bottom of the stop plate 8 to cooperate with the traction rod 5. A pressure plate 10 is rotatably connected to the top of the guide frame 1 through a bearing. The bottom of the pressure plate 10 is in close contact with the top of the stop plate 8. The bottom of the guide frame 1 is connected to the feed pipe 17. By setting the annular electrode 6, the jet of the nozzle 2 can be constrained. When it is necessary to remove the annular electrode 6, the pressure plate 10 can be rotated to disengage from the stop plate 8. Then the stop plate 8 is pulled upward. After the stop plate 8 rises, the limiting groove 9 no longer limits the traction rod 5. At this time, the annular electrode 6 can be rotated clockwise. The rotation of the annular electrode 6 drives the traction rod 5 to rotate. The rotation of the traction rod 5 drives the slider 4 to rotate. After the slider 4 rotates to the last side of the movable port 18, the annular electrode 6 can be pulled forward to disengage the slider 4 from the annular slide plate 3, thereby facilitating the removal and replacement of the annular electrode 6.

[0024] Specifically, a mounting base 11 is fixedly installed at the rear of the guide frame 1. A robotic arm connecting rod 12 is slidably connected inside the mounting base 11. A tube 13 is fixedly installed at the bottom of the U-shaped plate 7. The bottom end of the tube 13 passes through the mounting base 11 and the robotic arm connecting rod 12 and extends into the interior of the robotic arm connecting rod 12. A spring 14 is welded to the bottom of the inner cavity of the tube 13. A sliding rod 15 is welded to the top of the spring 14. The top end of the sliding rod 15 passes through the pressure plate 10 and extends to the outside of the pressure plate 10. The top of the pressure plate 10... A limiting port 16 is provided on the rear side to cooperate with the slide rod 15. By setting the mounting base 11 and inserting the robotic arm connecting rod 12 into the mounting base 11, and then pressing down the U-shaped plate 7, the insert 13 can pass through the mounting base 11 and be inserted into the robotic arm connecting rod 12 after the U-shaped plate 7 descends. Then, the pressure plate 10 is rotated so that the slide rod 15 passes through the pressure plate 10 and is limited by the limiting port 16, so as to facilitate the docking and disassembly of the guide frame 1 and the robotic arm connecting rod 12.

[0025] Working Principle: This utility model is a current-current inkjet printing device with a ring electrode constraining the jet. By setting the ring electrode 6, the jet of the printhead 2 can be constrained. When it is necessary to remove the ring electrode 6, the pressure plate 10 can be rotated to disengage from the abutment plate 8. Then, the abutment plate 8 is pulled upward. After the abutment plate 8 rises, the limiting groove 9 no longer limits the traction rod 5. At this time, the ring electrode 6 can be rotated clockwise. The rotation of the ring electrode 6 drives the traction rod 5 to rotate, and the rotation of the traction rod 5 drives the slider 4 to rotate. After the slider 4 rotates to the last side of the movable opening 18, it can be pulled forward. The moving annular electrode 6 disengages the slider 4 from the annular slide plate 3, thus facilitating the removal and replacement of the annular electrode 6. When it is necessary to connect the guide frame 1 and the robotic arm connecting rod 12, the robotic arm connecting rod 12 can be inserted into the mounting base 11, and then the U-shaped plate 7 can be pressed down. After the U-shaped plate 7 descends, the insert 13 can pass through the mounting base 11 and be inserted into the robotic arm connecting rod 12. Then, the pressure plate 10 is rotated, so that the slide rod 15 passes through the pressure plate 10 and is limited by the limiting port 16, thus facilitating the connection and disassembly of the guide frame 1 and the robotic arm connecting rod 12.
