[0002] Ink pressing process refers to the process of transferring ink from printing plate or anilox roller to the printing material by applying certain pressure during printing.

[0027] The following are the parameters of the structure of the utility model:

[0028] I, the rack 1

[0029] Dimension parameters

[0030] Length: The width of the fabric is generally 1.6 to 2.8 meters. There are almost no more than 2.8 meters of cloth. The rack width of the digital printing machine for printing 1.8 meters of fabric is more than 2 meters. The 10-meter-wide printer seen on the market is a UV printer in the advertising industry, which is another industry. There are also 3.4-meter-wide printers on the market, which print two 1.6-meter cloths.

[0031] The 10-meter-long rack belongs to one-pass printers, and the 2-meter-wide model belongs to scanners. The rack height is about 1 meter.

[0032] Material: Metal materials are usually used, such as steel racks, which may have a wall thickness of 16-25 mm to ensure sufficient strength to support other components and withstand various forces during printing.

[0033] Weight: The weight of the rack varies depending on the size and material, and the weight of a small device rack may be 400-500 kg, and the weight of a large industrial device rack may reach 1-5 tons.

[0034] Installation accuracy

[0035] Flatness: The flatness error of the upper surface of the gantry (used to mount components such as the guide belt 5) is controlled within the range of ±0.1 to ±0.5 mm to ensure the flatness of the guide belt, which in turn affects the printing quality.

[0036] II. Print carriage 2

[0037] Motion parameters

[0038] Speed: The movement speed of the print carriage on the gantry is fixed, depending on factors such as printing resolution, nozzle type, and printing material. For example, one-pass printing involves feeding the guide belt by one effective printing distance each time, which is related to different nozzles. Two-pass printing involves feeding the guide belt by 0.5 effective printing distances each time, and so on. The more passes, the better the printing effect.

[0039] Acceleration: In order to achieve fast start and stop and precise printing, the acceleration of the print carriage is generally between 0.5-5 m / s2. The acceleration size affects the printing efficiency and the stability of the ink ejection of the nozzle.

[0040] Positioning accuracy: The positioning accuracy on the gantry guide rail can reach ±0.01-±0.1 mm, ensuring that the nozzle can accurately print at the specified location.

[0041] Nozzle parameters (assuming the print carriage contains nozzles)

[0042] Number of nozzles: Depending on the printing requirements and equipment purposes, the number of nozzles can range from 1-100. For example, a simple monochrome printing device may have only 1-5 nozzles, while a device for large-format advertising, fabric printing, and other multi-color high-precision printing may have dozens or even hundreds of nozzles.

[0043] Nozzle resolution: The resolution of the nozzle can range from 300-2400 dpi (dots per inch). Higher resolution is used for high-quality image printing, while lower resolution is suitable for fast printing tasks with lower precision requirements.

[0044] III. Ink pressing mechanism 3

[0045] Pressure parameters

[0046] Ink pressing pressure: The pressure applied to the ink cartridge or ink tube during ink pressing is generally between 0.1-1 MPa. This pressure ensures stable supply of ink to the nozzle and can be adjusted according to factors such as ink viscosity and nozzle aperture.

[0047] Component dimensions

[0048] Ink roller size (if applicable): The diameter of the ink roller can range from 5 to 20 centimeters, and the length is determined by the printing width, generally matching the width of the guide belt, around 0.5 to 2 meters.

[0049] Four, the cloth roller 4

[0050] Pressure parameters

[0051] Cloth pressure: The pressure exerted by the cloth roller on the printing material such as fabric ranges from 10 to 100 N / cm 2 , to ensure that the printing material closely adheres to the guide belt, preventing displacement or wrinkles during printing. The pressure can be adjusted according to the thickness and hardness of the material.

[0052] Size parameters

[0053] Diameter: The diameter of the cloth roller is usually between 10 and 30 centimeters to ensure effective flattening of the material. The length matches the printing width, around 0.5 to 2 meters.

[0054] Five, the guide belt 5

[0055] Physical parameters

[0056] Material: The guide belt material can be polyester fiber, rubber, etc., with a thickness of 1 to 5 millimeters. Polyester fiber guide belts have good wear resistance and tensile resistance, while rubber guide belts have good elasticity and friction, suitable for different printing materials and processes.

[0057] Width: The width of the guide belt is determined by the printing width, with common widths ranging from 0.5 to 2 meters to accommodate different sizes of printing tasks.

[0058] Running speed: Matched with the speed of the printing trolley, between 0.1 and 2 meters per second, and the speed fluctuation during operation is controlled within ±0.01 meters per second to ensure the accuracy of printing.

[0059] Six, the cleaning mechanism 6

[0060] Cleaning fluid parameters (if applicable)

[0061] Cleaning fluid flow: When cleaning the spray head or other components, the cleaning fluid flow of the cleaning mechanism can range from 10 to 100 milliliters per minute to effectively remove residual ink and impurities.

[0062] Cleaning fluid pressure: The spray pressure of the cleaning fluid is generally between 0.05 and 0.3 MPa, sufficient pressure can fully flush the inside and surface of the spray head.

[0063] Cleaning cycle

[0064] The cleaning cycle can be set to clean every 1-10 hours of printing or automatically after each printing task, depending on the frequency of printing tasks and the characteristics of the ink.

[0065] Seven, sizing mechanism 7

[0066] Sizing parameters

[0067] Sizing amount: The amount of sizing can be adjusted according to the type and size of the printing material, generally between 1-10 milliliters per square centimeter, to ensure that the printing material can obtain appropriate pretreatment and improve the adhesion of the ink.

[0068] Sizing viscosity: The viscosity of the sizing ranges between 10-1000 mPa·s, different viscosities are suitable for different printing materials and ink systems, for example, lower viscosity sizing may be required for fiber materials, while higher viscosity sizing may be required for some special coating materials.

[0069] Eight, gear transmission mechanism 8

[0070] Transmission ratio

[0071] According to the speed requirements of different components, the transmission ratio of the gear transmission mechanism can be varied between 1:1-10:1. For example, in order to make the ink pressing mechanism and the sizing mechanism cooperate with the movement of the printing car at a suitable speed, the transmission ratio may be designed according to the specific movement parameters and component sizes.

[0072] Precision level

[0073] The precision level of the gear is generally between 6-9 levels to ensure the smoothness and accuracy of the transmission and reduce vibration and noise during transmission.

[0074] Nine, adjustment mechanism 9

[0075] Adjustment range

[0076] Position adjustment: The adjustment mechanism can adjust the ink pressing mechanism and the sizing mechanism in horizontal and vertical directions, with a horizontal adjustment range of ±0.1-±10 centimeters and a vertical adjustment range of ±0.1-±5 centimeters, to adapt to different specifications of ink cartridges, sizing containers and printing materials.
