Description

Technical Field

[0001] This invention relates to the field of digital printing technology, specifically to a method for eliminating the smell of digital printing ink. Background Technology

[0002] Digital printing is the digitization of printing technology. It broadly refers to the partial or complete digitization of the entire process. Examples include laser typesetting, remote plate transfer, digital proofing, computer-to-plate (CTP), digital workflows, and printing plant ERP systems.

[0003] Digital printing requires a digital printing press, as illustrated in Chinese Patent Publication No. CN115709920B, which falls under the field of printing press technology. To address the difficulty of uniformly combing the edges of the paper stock, manual combing is still required afterward, making it suitable only for small print runs. For large-volume printing, chaotic stacking easily occurs, making subsequent manual operation cumbersome. During the paper output process, the paper stock is closely fitted to the paper output channel, making it difficult to avoid adhesion due to incomplete ink drying. This invention utilizes a drying device to further process the paper stock. Ink drying allows the bottom surface of the paper stock to directly contact the air, which helps improve the printing quality of the paper stock. This invention uses a combing frame to comb the edges of several paper stock pieces neatly, making it easier to pick up the paper stock pile and complete the paper collection process of the digital printing machine. This not only improves the printing quality of the paper stock, but also achieves automated stacking while ensuring that the edges of the paper stock pile are neat, which helps improve the paper output efficiency of the printing machine. The above patent achieves automated stacking during use, but it cannot eliminate the ink smell. As a result, the ink smell can easily pollute the air around the digital printing machine when the user is using it, and the ink smell cannot be eliminated, thus affecting the user's health.

[0035] As a technical optimization of the present invention, digital printing can be performed by setting up a digital printing machine 1.

The inkjet printing mechanism 105 performs digital printing on the paper, the dryer 104 dries the printed paper, and the exhaust cooling box 106 allows external cold air to enter and cool the paper.

[0036] refer to Figure 5 The lifting mechanism 2 includes a motor 21, which is fixedly connected to the four corners of the top of the inkjet printing mechanism 105. The output end of the motor 21 is fixedly connected to a pulley 22. The front and rear ends of the pulley 22 are provided with pulleys 23. The surface of the pulleys 23 is connected to the pulleys 22 via a belt. The bottom of the pulleys 23 is fixedly connected to a threaded rod 24.

[0040] refer to Figure 3 The inkjet printing mechanism 105 includes an inkjet printing shell 1051. An ink printer 1052 is movably connected to the front and rear ends of the top of the inner wall of the inkjet printing shell 1051. Support plates 1053 are movably connected to both sides of the front and rear ends of the ink printer 1052.

[0041] As a technical optimization of the present invention, by setting up an inkjet printing mechanism 105, paper can be printed. When the lifting mechanism 2 moves the inkjet printing shell 1051 downward, the inkjet printing shell 1051 opens the printing head and prints the paper through the printing head of the inkjet printing shell 1051. When the lifting mechanism 2 moves the inkjet printing shell 1051 upward, the inkjet printing shell 1051 closes the printing head to avoid continuous inkjet spraying from the printing head of the inkjet printing shell 1051.

[0042] refer to Figure 1 A transmission belt 5 is fixedly installed inside the chassis 103, and a support leg 6 is fixedly connected to the bottom of the base plate 101.

[0043] As a technical optimization of the present invention, the paper can be transported by setting the transmission belt 5, and the base plate 101 can be supported by setting the support legs 6 to prevent the base plate 101 from contacting corrosive substances on the ground.

[0044] refer to Figure 4 The bottom of the exhaust fan 41 is fixedly connected to a connecting seat 7, and the four corners of the top of the connecting seat 7 are fixedly connected to the top of the exhaust cooling box 106 by bolts and nuts.

[0045] As a technical optimization of the present invention, by setting the connecting seat 7, the exhaust fan 41 can be fixed to prevent the exhaust fan 41 from shaking.

[0046] refer to Figure 5 Fixed bearings 8 are fixedly connected to the top and bottom of the threaded rod 24. The outer ring of the fixed bearing 8 is fixedly connected to the inner wall of the support plate 1053.

[0047] As a technical optimization of the present invention, by setting a fixed bearing 8, the threaded rod 24 can be fixed to prevent the threaded rod 24 from shaking.

[0048] The working principle and usage process of this invention are as follows: During use, the user drives the dryer 104, inkjet printing mechanism 105, ink printer 1052, motor 21, exhaust fan 35, and exhaust fan 41 via the control console 102. Paper is placed on top of the transmission belt 5, which moves the paper to the bottom of the inkjet printing mechanism 105. The user drives the motor 21, which rotates pulley 22. Pulley 22, via a belt, rotates pulley 23. Pulley 23 rotates the threaded rod 24, which in turn moves the square threaded sleeve 25 downwards. The square threaded sleeve 25 moves the connecting block 26 downwards, which in turn moves the ink printer 1052 downwards. As the ink printer 1052 moves downwards, it prints on the paper. The exhaust fan 35, through the connecting pipe 36, circulates ink through the inner part of the ink guide groove 34. The ink guide trough 34 draws out the ink droplets remaining on the ink printer 1052 through the exhaust trough 33. The ink droplets are sucked away by the negative air pressure and then transported to the bottom of the dryer 104 by the conveyor belt 5. The dryer 104 drives the drying heating plate 1043 through the dryer shell 1042 to heat the paper. The drying heating plate 1043 bakes the paper. At the same time, the second exhaust fan 41 draws air through the limiting pipe 43 through the connecting pipe 42. The limiting pipe 43 draws air through the exhaust head 44 to the inside of the drying shell 1041 and the exhaust cooling box 106, so that the ink gas volatilized during the baking of the paper enters the inside of the exhaust head 44. The exhaust head 44 transmits the ink gas into the inside of the second exhaust fan 41 through the limiting pipe 43 and the connecting pipe 42. The second exhaust fan 41 transmits the ink gas into the inside of the connecting pipe 45. The connecting pipe 45 transmits the ink gas into the factory's exhaust system.

[0049] In summary, this method for eliminating the smell of digital printing ink utilizes an ink extraction mechanism 3 to generate negative air pressure, which draws away ink droplets adhering to the printhead. The extraction mechanism 4 then draws air from the inside of the dryer 104, eliminating the ink fumes produced by ink evaporation. This ensures that the ink odor does not pollute the surrounding air of the digital printer 1 during use, thus protecting the user's health.
