[0032] The material passing platform system 2 is used for conveying and positioning the products to be inkjet printed. The material passing platform system 2 includes a suction platform 21. The driven guide beam 11 and the driving guide beam 12 are both arranged on the top of the suction platform 21. A feeding system 3 is used for conveying the products to be inkjet printed onto the suction platform 21. A receiving and transition platform system 4 is used for guiding the products after inkjet printing to the packing process. Figure 10 It is a schematic structural diagram of the whole device after installing the housing, with a more beautiful appearance and more convenient use.

[0033] As a specific technical solution of this embodiment, slide rails 14 are arranged on the opposite sides of the driven guide beam 11 and the driving guide beam 12. The driven inkjet printing trolley 17 and the driving inkjet printing trolley 16 are respectively slidably installed on the driven guide beam 11 and the driving guide beam 12 through the slide rails 14. The setting of the slide rails 14 makes the movement of the driving inkjet printing trolley 16 and the driven inkjet printing trolley 17 more stable.

[0034] As a specific technical solution of this embodiment, a transmission belt with a surface fixedly connected to one side of the driving inkjet printing trolley 16 is arranged on one side of the driving guide beam 12. The transmission belt is driven by a main transmission servo motor 15. The ink absorption device 13 includes a fixing plate 131, an ink absorption table 132 and an ink supply rack 135.

[0036] As a specific technical solution of this embodiment, the inside of the air suction platform 21 is provided with at least one air suction cover plate 22 and a conveyor belt 43. A conveyor motor 24 is provided on one side of the air suction platform 21. The inside of the air suction platform 21 is provided with two groups of transmission shafts 25, and the two groups of transmission shafts 25 are connected by the conveyor belt 43. The output end of the conveyor motor 24 is connected to one group of transmission shafts 25 in a transmission manner. An air suction device is provided inside the air suction platform 21. The product to be inkjet printed is adsorbed through the air suction cover plate 22, so that the product maintains good stability during inkjet printing, further ensuring the inkjet printing accuracy. After the inkjet printing is completed, the conveyor motor 24 is started to drive the conveyor belt 23 to convey the product to the guiding frame 41.

[0037] As a specific technical solution of this embodiment, the feeding system 3 includes a feeding rack 31 provided on one side of the air suction platform 21. An installation rack 32 is provided on the top of the feeding rack 31. The inside of the installation rack 32 is provided with at least one pressing roller 33. The product to be inkjet printed is placed at the feeding rack 31 and pushed onto the air suction platform 21. The pressing roller 33 continuously presses down on the product to ensure the flatness of the product.

[0038] As a specific technical solution of this embodiment, the receiving and transition platform system 4 includes a guiding frame 41 provided on the side of the air suction platform 21 away from the feeding rack 31. The inside of the guiding frame 41 is provided with a conveyor belt 43. Protective enclosures 42 are provided on both sides of the guiding frame 41. Refer to Figure 3 , the conveyor belt 43 inside the guiding frame 41 can be connected to the transmission shaft 25 using a belt to achieve the synchronous rotation of the conveyor belt 23 and the conveyor belt 43, which is more convenient for conveying the inkjet printed product.

[0039] During use, the working precision of this device mainly has two modes:

[0040] Mode 1: 600 DPI, wide-format digital printing. In this mode, 1200 DPI is decomposed into two 600 DPI, with the precision reduced by half and the width of the printable pattern doubled. This mode is mainly applied to patterns with general precision. The printed pattern can be printed horizontally or vertically. When the printed pattern is large, it can be printed horizontally, with a fast printing speed and high production efficiency.

[0041] Mode 2: 1200 DPI, high-precision digital printing. In this mode, two 600 DPI are combined into one 1200 DPI. Compared with the 600 DPI mode, the precision is doubled, and the width of the printable pattern is reduced by half. This mode is applied to the printing of high-precision patterns, mainly printed on coated paper with a coating. This printed pattern is mainly printed vertically with high precision.

[0042] The device is automatically controlled by the printing system. The product to be printed is pushed onto the suction platform 21 by the feeding rack 31. When the 600 DPI precision mode 1 is selected in the operating system, the control system sends a signal to the main drive servo motor 15. The main drive servo motor 15 drives the active printing carriage 16 to move leftward away from the origin through the transmission belt. When the active printing carriage 16 moves to a certain position and remains opposite to the driven printing carriage 17, the positioning cylinders 162 on the driven printing carriage 17 and the active printing carriage 16 and the positioning cylinder 171 are activated. The positioning pin 163 is inserted into the inside of the positioning guide seat 173, and at the same time, the positioning pin 172 is inserted into the inside of the positioning guide seat 161. The active printing carriage 16 continues to move and drives the driven printing carriage 17 to move to the corresponding position to print the pattern on the product. Whether the active printing carriage 16 drives the driven printing carriage 17 to move depends on the width of the pattern to be printed input into the control system. When the width of the pattern to be printed is less than the width printed by the active printing carriage 16, the active printing carriage 16 does not need to drive the driven printing carriage 17, that is, the positioning cylinders 162 and 171 do not act, and the active printing carriage 16 directly moves to the corresponding position to print the pattern on the product. On the contrary, when the width of the pattern to be printed is greater than the width printed by the active printing carriage 16, the positioning cylinders 162 on the driven printing carriage 17 and the active printing carriage 16 and the positioning cylinder 171 are activated, so that the active printing carriage 16 and the driven printing carriage 17 are linked; when the 1200 DPI precision mode 2 is selected in the operating system, the active printing carriage 16 and the driven printing carriage 17 do not move at the origin. Wait for the positioning cylinders 162 and 171 to be activated to complete the linkage locking of the active printing carriage 16 and the driven printing carriage 17, and then the main drive servo motor 15 can be started to drive the active printing carriage 16 and the driven printing carriage 17 to move from the origin position to the corresponding position to print the pattern on the product. After the printing work is completed, the conveying motor 24 drives the conveyor belt 1 23 to convey the product, and the staff can receive the product at the guiding frame 41 and pack it into a box. Through the above, the operation of the device is completed.

[0043] In summary, compared with the digital printing machines with a single precision on the market, this high-speed dual physical reference resolution digital printing machine is multi-functional by setting the digital inkjet printing system 1. The physical reference resolution can be adjusted and interchanged, with multiple printing precisions, saving labor and the reset of fixed assets resources in the factory. The machine structure is simple, the system operation is convenient, time and labor are saved, the production efficiency is high, it meets the economic benefits, and has a broad application prospect.
