[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] like Figure 1 and Figure 2 As shown, a double-sided synchronous drying and mixing printing device includes: a frame 20, the frame 20 having a rectangular table surface, and support legs installed at the bottom of the frame 20;

[0029] The take-up frame 21 is symmetrically and fixedly connected to the top of the rear wall of the frame 20. The printing machine body 22 is fixedly connected to the top of the front wall of the frame 20. The printing machine body 22 is a traditional hybrid double-sided printing machine. The take-up frame 21 holds the take-up roll during use. The printing machine body 22 is electrically connected to the corresponding power supply. This is existing technology, so it will not be described in detail here.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a quick-drying structure is installed at the top middle section of the frame 20 to dry the printed material. The quick-drying structure includes: a water suction pipe 30, a lower air duct 33, an air outlet pipe 34, a guide plate 35, and an upper air duct 37. The water suction pipe 30 is fixedly connected to the top of the frame 20. The lower air duct 33 is fixedly connected to the top of the frame 20 behind the water suction pipe 30. The air outlet pipe 34 is symmetrically fixedly connected to the top of the lower air duct 33. The guide plate 35 is also symmetrically fixedly connected to the top of the lower air duct 33. The upper air duct 37 is fixedly installed above the lower air duct 33. The printed material will pass through the space between the upper air duct 37 and the lower air duct 33.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the water suction pipe 30 is rectangular with its opening facing upwards. A water pump connected to the water suction pipe 30 is installed at the bottom of the frame 20. The lower air duct 33 is a hollow rectangle. The air outlet pipe 34 is rectangular and is positioned at an angle at the top of the lower air duct 33. The bottom of the air outlet pipe 34 is connected to the cavity of the lower air duct 33. Each guide plate 35 is located at the air outlet pipe 34 and is arc-shaped. The inner arc surface of the guide plate 35 is aligned with the opening of the air outlet pipe 34. A rectangular plate is fixedly connected to one side wall of the lower air duct 33. The side wall of the upper air duct 37 is aligned with the side wall of the lower air duct 33. The rectangular plate is fixedly connected to the side wall. The quick-drying structure also includes a lower pressure roller 31, an upper pressure roller 32, and a heating plate 36. The lower pressure roller 31 is rotatably connected to the top opening of the water pumping pipe 30. The upper pressure roller 32 is located above the lower pressure roller 31. The heating plate 36 is fixedly connected to the top of the symmetrical air outlet pipe 34. The lower pressure roller 31 and the upper pressure roller 32 are cylinders of the same size. The water pumping pipe 30 has a rectangular support fixedly connected to the rectangular plate on the same side as the wall of the lower air duct 33. The upper pressure roller 32 is rotatably connected to the rectangular support on the side wall of the water pumping pipe 30. The heating plate 36 is an arc-shaped plate with the inner arc surface facing upward. The heating plate 36 is located directly below the upper air duct 37.

[0032] In practical use, the material to be printed is first passed through the wall of the printing press body 22, then through the space between the upper air duct 37 and the lower air duct 33, and then its end is fixedly connected to the roll placed on the wall of the take-up frame 21. Then the power is turned on, and the roll on the wall of the take-up frame 21 will continue to rotate and rewind. The printing press body 22 will perform double-sided mixed printing on the material passing through its wall. After the material is printed, it will pass through the space between the lower pressure roller 31 and the upper pressure roller 32. At this time, the water suction pipe 30 will also draw the bottom of the material because its water pump power is turned on. At this time, the space between the lower pressure roller 31 and the upper pressure roller 32 The excess moisture mixed in the material will be squeezed out and then pumped towards the water pump by the water pumping pipe 30. The upper air duct 37 and the lower air duct 33 will be connected to the hot air fan. At this time, the heat blown out by the hot air fan will be discharged from the bottom of the air outlet pipe 34 and the upper air duct 37. The discharged hot air will contact the upper and lower walls of the material simultaneously. The guide plate 35 will concentrate the hot air blown out by the air outlet pipe 34 and guide it towards the other side. The surface temperature of the heating plate 36 will increase as it absorbs heat for a long time, thereby releasing heat to assist in drying the material above. After the material passes between the upper air duct 37 and the lower air duct 33, it will be wound up on the roll on the wall of the winding rack 21.

[0033] In summary, by setting up a quick-drying structure and using negative pressure pumping combined with hot air drying, the printed materials can be dried quickly, thus avoiding the problem of incomplete drying requiring secondary drying. Therefore, this solution has a highly efficient drying effect.

[0034] like Figure 2 and Figure 3 As shown, the wall of the upper air duct 37 is provided with a covering structure, which includes a fixed block 40, a baffle 41 and a limiting edge 42. The fixed block 40 is symmetrically fixed to the outer wall of the upper air duct 37. The baffle 41 is slidably connected to the side wall of the upper air duct 37 on the same side as the fixed block 40. The limiting edge 42 is symmetrically fixed to the front and rear walls of the baffle 41. The fixed block 40 is a rectangular block. The position of the baffle 41 is opposite to the rectangular plate on the side wall of the lower air duct 33. The baffle 41 can block the openings on the side walls of the upper air duct 37 and the lower air duct 33. The symmetrical limiting edges 42 have rectangular grooves on their respective walls facing each other to accommodate the sliding of the fixed block 40. The symmetrical fixed block 40 is engaged in the rectangular grooves on the walls of the symmetrical limiting edges 42.

[0035] In practical use, when guiding the material end to the drum, the baffle 41 can be pushed upward to open the openings on the side walls of the upper air duct 37 and the lower air duct 33. At this time, the material can be put in from the side and passed between the upper air duct 37 and the lower air duct 33. Then the baffle 41 can be pushed downward to cover the openings on the side walls of the lower air duct 33 and the upper air duct 37.

[0036] In summary, by setting up a covering structure, the heat loss between the upper air duct 33 and the upper air duct 37 can be reduced by using a sliding baffle 41 to block the openings on the side walls of the upper air duct 37 and the lower air duct 33, thereby reducing the power consumption of this solution.

[0037] Working principle: First, the material to be printed passes through the wall of the printing machine body 22, then through the space between the upper air duct 37 and the lower air duct 33. Its end is then fixedly connected to the roll placed on the wall of the take-up frame 21. Then, the power is turned on, and the roll on the wall of the take-up frame 21 will continuously rotate and rewind. The printing machine body 22 will perform double-sided mixed printing on the material passing through its wall. After printing, the material passes between the lower pressure roller 31 and the upper pressure roller 32. At this time, the water pump 30 will also pump the bottom of the material due to the power being turned on. The material is being pumped, and at this time, the excess water mixed in with the material is squeezed between the lower pressure roller 31 and the upper pressure roller 32 and then pumped towards the water pump by the water pumping pipe 30. The upper air duct 37 and the lower air duct 33 are connected to the hot air fan. At this time, the heat blown out by the hot air fan will be discharged from the bottom of the air outlet pipe 34 and the upper air duct 37. The discharged hot air will contact the upper and lower walls of the material simultaneously. The guide plate 35 will concentrate the hot air blown out by the air outlet pipe 34 and guide it towards the other side. Then, after the material passes through the upper air duct 37 and the lower air duct 33, it will be wound up on the roll on the wall of the winding frame 21.
