The support plate 1 is vertically provided with a slide groove 19 located below the first sprocket 14 at one end close to the first sprocket 14, and a slide plate 20 is vertically slidably connected in the slide groove 19. The end of the slide plate 20 away from the bottom of the slide groove 19 is rotatably connected to the fourth sprocket 21. The fourth sprocket 21 is connected to the third sprocket 18 and the first sprocket 14 through a second chain 22. A tension spring 23 is provided between the bottom end of the slide plate 20 and the bottom end groove wall of the slide groove 19.

[0032] like Figure 1 and Figure 3When the conveyor belt 6 transports the book 55, the conveyor belt 6 drives the second sprocket 16 to rotate through the first chain 17, and the second sprocket 16 drives the third sprocket 18 to rotate through the rotating shaft 15. At this time, the third sprocket 18 drives the first sprocket 14 and the fourth sprocket 21 to rotate through the second chain 22, and the first sprocket 14 drives the first pressing roller 9 to rotate, so that one end of the book 55 can pass under the first pressing roller 9; By opening the two first electric cylinders 13, the piston rods of the two first electric cylinders 13 push the two mounting plates 8 to move vertically synchronously. At this time, the spacing between the first pressure roller 9 and the conveyor belt 6 can be adjusted to adapt to books 55 of different thicknesses. The tension spring 23 is always in a stretched state. When the piston rod of the first electric cylinder 13 pushes the mounting plate 8 to move vertically, the cooperation of the tension spring 23, the slide plate 20, the slide groove 19, the second chain 22, the fourth sprocket 21, the third sprocket 18 and the first sprocket 14 can make the slide plate 20 move vertically following the mounting plate 8. During or after the movement of the mounting plate 8, the first chain 17 will not affect the rotation of the second sprocket 16. The second sprocket 16 drives the third sprocket 18 to rotate through the rotating shaft 15. The third sprocket 18 drives the first sprocket 14 and the fourth sprocket 21 to rotate through the second chain 22. The first sprocket 14 drives the first pressure roller 9 to rotate. It is simple and convenient to use.

[0033] like Figure 3 and Figure 4 The transmission member includes first gears 24 that are both arranged on the first pressure roller 9 and each second pressure roller 10. The number of first gears 24 on the first pressure roller 9 is two and they are arranged opposite to each other. A plurality of second gears 25 are rotatably connected to the two mounting plates 8. Each second gear 25 is respectively located between two adjacent first gears 24, and the second gear 25 is meshed with two adjacent first gears 24. The purpose of this arrangement is that when the first pressure roller 9 rotates, the second pressure roller 10 can be rotated synchronously through the cooperation of each first gear 24 and each second gear 25. At this time, it is convenient for one end of the book 55 to pass under the second pressure roller 10. The second pressure roller 10 rotates in the same direction as the first pressure roller 9, which is simple and convenient to use.

The purpose of this arrangement is that the power member drives each second column 27 to move toward or away from the first column 26 at the same time, so that the length of the second pressing roller 10 can be adjusted to adapt to books 55 of different widths. When the second column 27 moves toward or away from the first column 26, the second column 27 drives the square plate 29 to slide out of or into the square groove 28. The end of the square plate 29 close to the bottom of the square groove 28 is always located in the square groove 28. The retaining ring 30 contacts the side wall of the book 55, which can further reduce the deviation of the book 55 during printing, causing the misalignment of the printed text or graphics. After the first book 55 passes under the first pressing roller 9 and each second pressing roller 10, the second book 55 is transported to the first pressing roller 9 and each second pressing roller 10 through the conveyor belt 6. At this time, there is no need to adjust the distance between the first pressing roller 9 and the conveyor belt 6 and the length of the second pressing roller 10 again. Books 55 of the same specification can be printed continuously, which is simple and convenient to use.

[0035] like Figure 1 and Figure 4 The power member includes a swivel 32 which is coaxially rotatably connected to each second column 27, and the swivel 32 is located on the side of the retaining ring 30 close to the mounting plate 8.

The top ends of the vertical plates 37 are rotatably connected with transmission gears 39, and the transmission gears 39 are located between the two racks 38 and meshed with the two racks 38. A second electric cylinder 40 for pushing one of the vertical plates 37 to move horizontally is provided on the top plate 31.

[0036] like Figure 1 and Figure 4 When it is necessary to drive each second column 27 to move in a direction close to or away from the first column 26 at the same time, it is only necessary to open the second electric cylinder 40, and the piston rod of the second electric cylinder 40 pushes one of the vertical plates 37 to move horizontally. At this time, because the transmission gear 39 is meshed with the racks 38 on the two vertical plates 37, when one of the vertical plates 37 moves horizontally, the two vertical plates 37 can be moved in a direction close to or away from each other through the cooperation of the transmission gear 39 and the racks 38 on the two vertical plates 37. At this time, the two sleeves 34 will move with the two vertical plates 37 respectively. At the same time, the sleeve 34 will drive each second column 27 to move in a direction close to or away from the first column 26 at the same time through the cooperation of the driving column 35, the swivel 32 and the connecting column 33, thereby adjusting the length of the second pressing roller 10 to adapt to books 55 of different widths. The sides of the two sleeves 34 that are close to each other are in contact with the side wall of the book 55, which is simple and convenient to use.

At this time, when the air pump 54 is working, the air outlet 48 can always blow air toward the upper surface of the book 55, thereby improving the drying efficiency. An air filter plate (not shown in the figure) is provided at the pipe mouth of the air inlet pipe 42 away from the heating box 41. When adjusting the length of the second pressing roller 10, since the closing plate 47 is arranged in the circular groove 45 on the second column 27, when the second column 27 moves toward or away from the first column 26, the position of the closing plate 47 can be adjusted according to the length of the second pressing roller 10 of the book, thereby adjusting the blowing position, so that the wind blown out from each air outlet on the closing plate 47 is blown to both sides of the upper surface of the book 55, thereby reducing the situation that the wind blown out from each air outlet blows to the two side walls of the book 55 and cannot blow to the upper surface of the book 55 due to the different specifications of the two batches of books 55. In addition, since the wind blown out from each air outlet on the closing plate 47 is inclined downward and blows to both sides of the upper surface of the book 55, the situation that the hot air is blown to the book 55 when the printing component 3 is working is reduced. Because the closing plate 47 is arranged in the circular groove 45 on the second column 27, when the bottom end of the outer wall of the second column 27 contacts the upper surface of the book 55, the distance between the closing plate 47 and the book 55 will not change due to the different specifications of the book 55. At this time, the situation that the distance between the closing plate 47 and the book 55 is different due to the different specifications of multiple batches of books 55, which affects the drying effect, can be reduced. The use is simple and convenient.
