Description

Technical Field

[0001] This utility model relates to the field of inkjet printing technology, and in particular to an inkjet printing cleaning device based on negative pressure. Background Technology

[0002] Inkjet printing technology, as a non-contact printing method, has been widely used in many fields such as electronics manufacturing, packaging printing, and 3D printing due to its high precision, high flexibility and wide applicability to materials.

[0003] Existing inkjet printers inevitably generate various impurities during the printing process, mainly including: aerosols formed by ink atomization at the printhead nozzles, excess ink droplets splashed during high-speed jetting, and dust floating in the environment. If these impurities are not dealt with in time, they will adhere to the surface of the item to be printed, causing print pattern contamination and defects; at the same time, impurities may clog the printhead nozzles, leading to uneven ink jetting, or even damaging the printhead, increasing equipment maintenance costs and downtime. Utility Model Content

The mounting assembly is mounted on the print table. The mounting plate, guide assembly, and drive assembly are all mounted on the mounting assembly. The printing assembly and negative pressure assembly are both mounted on the mounting plate. The drive assembly is connected to the guide assembly, and the guide assembly is connected to the mounting plate. The mounting plate is located on a first plane parallel to the print table.

The printing assembly includes an ink sac fixedly mounted on the mounting plate and a print head connected to the ink sac and capable of inkjet printing on items placed on the print table.

The second mounting base is movably mounted on the two first mounting bases and connected to the two first screws. The two first motors can be driven by the two first screws. A screw drives a second mounting base to move in a first direction. A second motor is mounted on the second mounting base. The second screw is mounted on the second mounting base and arranged in a second direction. The second motor is connected to the second screw. A third mounting base is movably mounted on the second mounting base and connected to the second screw.

A mounting plate is movably mounted on the third mounting base and connected to the third screw. The third motor can drive the mounting plate to move in a third direction via the third screw.

[0007] Preferably, the second mounting base is located on a second plane parallel to the first plane, and the mounting plate can move on the first plane or on any third plane parallel to the first plane between the second plane and the printing table.

[0008] Preferably, the first direction, the second direction, and the third direction are perpendicular to each other, and the third direction is a vertical direction.

[0018] refer to Figure 1-3 This utility model proposes a negative pressure-based inkjet printing cleaning device, comprising: a printing table 1, a mounting plate 2, a mounting assembly, a guide assembly, a drive assembly, a printing assembly, and a negative pressure assembly. The mounting assembly is mounted on the printing table 1, providing a solid support foundation for the entire device. The mounting plate 2, the guide assembly, and the drive assembly are all mounted on the mounting assembly, and the three cooperate with each other to move the mounting plate 2. The printing assembly and the negative pressure assembly are fixed on the mounting plate 2 and move synchronously with the mounting plate 2 to ensure the coordinated operation of printing and negative pressure adsorption.

[0019] The drive assembly is connected to the guide assembly, which in turn is connected to the mounting plate 2. The drive assembly provides power, and the guide assembly guides the direction, which can drive the mounting plate 2 to move within a specific plane. Specifically, the mounting plate 2 is initially located on a first plane parallel to the print table 1, and the mounting assembly is located on a second plane parallel to the first plane. The drive assembly can drive the mounting plate 2 to move on the first plane or on any third plane parallel to the first plane between the second plane and the print table 1, flexibly adapting to different printing needs.

[0020] The printing assembly includes an ink sac 3 and a print head 4. The ink sac 3 is fixedly mounted on the mounting plate 2 and continuously supplies ink to the print head 4. The print head 4 is connected to the ink sac 3 and can perform inkjet printing on items placed on the printing table 1. The design of its nozzle area ensures the uniformity and accuracy of ink jetting. The negative pressure component is located on the side of the printing assembly and has an air inlet facing the print head 4, which can promptly handle impurities generated during the printing process.

[0021] The mounting components include two first mounting bases 5, a second mounting base 6, and a third mounting base 7. The two first mounting bases 5 are fixedly installed on both sides of the printing table 1 and are symmetrically arranged along the first direction (e.g., the X-axis direction) to ensure the stability of the support. The second mounting base 6 and the third mounting base are both made of sturdy and durable metal materials to withstand the weight of each component and the force during the movement.

[0022] The guiding assembly includes two first screws 51, a second screw 61, and a third screw 71. These screws are precision machined with extremely low surface roughness to ensure smooth transmission. The driving assembly consists of two first motors 52, a second motor 62, and a third motor 72. All motors are servo motors, which have the characteristics of high precision and high response speed.

[0023] Two first motors 52 are respectively mounted on two first mounting bases 5, and their output shafts are connected to two first screws 51. The two first screws 51 are arranged on the two first mounting bases 5 along the first direction. The second mounting base 6 is movably mounted on the two first mounting bases 5, and each end of the second mounting base 6 is equipped with a first nut 53. The two first nuts 53 are respectively connected to the two first screws 51 for transmission. When the two first motors 52 are started, they drive the first screws 51 to rotate. Through the threaded engagement between the first nuts 53 and the first screws 51, the second mounting base 6 is driven to move smoothly along the first direction.

[0024] The second motor 62 is mounted on the second mounting base 6, and its output shaft is connected to the second screw 61. The second screw 61 is mounted on the second mounting base 6 along the second direction (e.g., the Y-axis direction). The third mounting base 7 is fixedly mounted with a second nut. The second nut is connected to the second screw 61 in a transmission connection. When the second motor 62 is working, it drives the third mounting base 7 to move along the second direction through the cooperation of the second screw 61 and the second nut.

[0025] The third motor 72 is mounted on the third mounting base 7, and its output shaft is connected to the third screw 71. The third screw 71 is mounted on the third mounting base 7 along the third direction (e.g., the Z-axis direction, i.e., the vertical direction). The third nut 73 is fixedly mounted on the mounting plate 2. The third nut 73 is connected to the third screw 71 in a transmission connection. After the third motor 72 is started, the mounting plate 2 is driven to move along the third direction through the cooperation of the third screw 71 and the third nut 73.

[0026] It is worth noting that the first direction, the second direction, and the third direction are perpendicular to each other. This spatial layout allows the mounting plate 2 to move precisely in three-dimensional space, meeting the requirements of different printing positions and heights. At the same time, the second mounting base 6 is located on a second plane parallel to the first plane. The mounting plate 2 can move on the first plane or on any third plane parallel to the first plane between the second plane and the printing table 1. There are countless third planes, and their positions are uncertain. They can be located between the second mounting base 6 and the printing table 1 to further expand the range of printing operations.

[0027] The negative pressure assembly includes a negative pressure generator 8 and two suction nozzles 9, which are fixedly mounted on the mounting plate 2. The negative pressure generator 8 is a high-efficiency and energy-saving model that can quickly generate stable negative pressure. The suction nozzles 9 are made of corrosion-resistant and wear-resistant materials and are connected to the negative pressure generator 8 through high-pressure resistant pipelines.

[0028] The two suction nozzles 9 are located in front of and behind the print head 4 along the printing movement direction. This layout can capture impurities generated during the printing process from all directions. The opening of the suction nozzle 9 forms an air inlet, and the air inlets of the two suction nozzles 9 are set directly opposite the nozzle area of ​​the print head 4, which can accurately guide the aerosol and splash ink droplets generated during the printing process into their own interior.

[0029] When the printhead 4 performs inkjet printing, the negative pressure generator 8 starts simultaneously, creating negative pressure at the suction nozzle 9. The front suction nozzle 9 can promptly remove airborne dust about to enter the printing area, as well as aerosols and splashed ink droplets generated when the printhead 4 moves forward. The rear suction nozzle 9 can clean up residual aerosols and ink droplets after printing, effectively preventing these impurities from contaminating the surface of the printed items and the printhead 4, significantly improving print quality and the lifespan of the printhead 4.

[0030] In summary, this negative pressure-based inkjet printing pneumatic stabilization device, through the precise coordination of its components, achieves control of the printing process and removal of impurities, providing a reliable guarantee for inkjet printing operations.
