[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5This utility model provides an embodiment of an automatic adjustment device for a printing production line, comprising a base 1 and a conveyor belt 2. The conveyor belt 2 is installed inside the base 1, and a protective frame 3 is fixedly installed on the outside of the base 1. A driving mechanism 4 is provided on the top of the protective frame 3. The driving mechanism 4 includes an air pump 41, pneumatic push rods 42, a first fixing plate 43, fixing rods 44, a second fixing plate 45, and a printing plate 46. The air pump 41 is fixedly installed on the top of the protective frame 3. Two sets of pneumatic push rods 42 are fixedly installed at the lower end of the air pump 41. The lower end of the pneumatic push rods 42 is fixedly connected to the first fixing plate 43. Four sets of fixing rods 44 are fixedly connected to the four corners of the lower end of the first fixing plate 43. The lower end of the fixing rods 44 is fixedly connected to the second fixing plate 45. The lower end of the printing plate 46 is provided with a printing plate 46. The second fixing plate 45... A smoothing assembly 5 is provided on both sides of the second fixed plate 45. The smoothing assembly 5 includes a positioning block 51, a first connecting rod 52, a roller 53, and a reset assembly 54. Two sets of positioning blocks 51 are fixedly installed on the front and rear sides of the second fixed plate 45. The left and right sides of the positioning block 51 are respectively rotatably connected to the first connecting rod 52. The other end of the two sets of first connecting rods 52 is rotatably connected to the roller 53. The reset assembly 54 is provided inside the positioning block 51. The air pump 41 is started to drive the pneumatic push rod 42 to drive the first fixed plate 43 and the second fixed plate 45 to descend. When the first fixed plate 43 descends, the rollers 53 on both sides contact the paper surface. Under the action of the first connecting rod 52 and the positioning block 51 rotatably connecting, the rollers 53 move along the paper to smooth the paper. Then, the printing plate 46 prints on the paper surface.

[0025] This device, through the setting of the leveling component 5, solves the problem that when paper is transported, vibrations can easily cause it to shake, resulting in gaps between the papers. Direct printing with these gaps can lead to slight paper displacement and errors.

[0026] Furthermore, the reset assembly 54 includes a first movable rod 541, a connecting ring 542, a first spring 543, and a second connecting rod 544. The first movable rod 541 is movably connected to the center position of the positioning block 51. The connecting ring 542 is fixedly connected to the bottom of the first movable rod 541. The first spring 543 is movably sleeved on the outer side of the first movable rod 541. The two ends of the first spring 543 abut against the inner walls of the connecting ring 542 and the positioning block 51, respectively. Two sets of second connecting rods 544 are rotatably connected to the left and right sides of the connecting ring 542. The other end of the second connecting rod 544 is rotatably connected to the center position of the first connecting rod 52. Figure 4As shown, when printing through the printing plate 46, the roller 53 drives the first connecting rod 52 to rotate outward. The roller 53 is rotatably connected to the first connecting rod 52 through the second connecting rod 544, which pulls the second connecting rod 544 to rotate outward. At the same time, the bottom of the connecting ring 542 contacts the conveyor belt 2 and moves upward along the hole of the positioning block 51, squeezing the first spring 543. When the printing is completed and the roller rises, the first spring 543 pushes the connecting ring 542 and the first movable rod 541 to descend along the hole of the positioning block 51, restoring the first movable rod 541 to its original position and causing the two sets of second connecting rods 544 to pull the first connecting rod 52 to reset.

[0027] Furthermore, an adjustment assembly 6 is provided within each of the four sets of fixed rods 44. The adjustment assembly 6 includes a movable groove 61, a second movable rod 62, and a damping spring 63. The fixed rods 44 have a movable groove 61 inside, and the second movable rod 62 is movably connected inside the movable groove 61. The lower end of the second movable rod 62 is connected to the printing plate 46 via the damping spring 63, and both ends of the damping spring 63 abut against the inner walls of the fixed rods 44 and the printing plate 46, respectively. Figure 5 As shown, this structure is used to drive the second movable rod 62 to move along the movable groove 61 when the printing plate 46 comes into contact with the paper. At the same time, the damping spring 63 is compressed and deformed. After printing is completed, the printing plate 46 is reset under the rebound action of the damping spring 63 to avoid uneven paper thickness and improve the applicability of the device.

[0028] Furthermore, a rotating shaft 7 is fixedly connected to the left opening of the protective frame 3, and a door curtain 8 is rotatably connected to the outside of the rotating shaft 7. A brush is provided at the bottom of the door curtain 8. Figure 2 As shown, this structure is used in conjunction with the rotating shaft 7 and the curtain 8 to clean the paper when it is being transported by the conveyor belt 2 to the outlet of the observation guard 3, with the bottom of the curtain 8 contacting the paper.

[0029] Furthermore, two sets of limiting blocks 55 are fixedly connected to the bottom of the positioning block 51, and the limiting blocks 55 are inclined at a 45-degree angle toward the first connecting rod 52. Figure 4 As shown, this structure is used to limit and guide the first connecting rod 52 through the limiting block 55, so that the first connecting rod 52 always remains in the open state and can move stably to both sides after descending.

[0030] Furthermore, a positioning plate 65 is movably connected to the top of the movable groove 61, and an adjusting rod 66 is fixedly connected to the upper end of the positioning plate 65. The adjusting rod 66 is threadedly connected to the first fixed plate 43. A second spring 64 is provided inside the movable groove 61, and the two ends of the second spring 64 abut against the second movable rod 62 and the positioning plate 65, respectively. Figure 5As shown, this structure is used to drive the positioning plate 65 down along the movable groove 61 by rotating the adjusting rod 66, thereby squeezing the second spring 64 and controlling the range of motion of the second movable rod 62.

[0031] Furthermore, four sets of observation windows 9 are symmetrically installed on the front and rear sides of the protective frame 3, and the observation windows 9 are horizontally positioned with the conveyor belt 2. Figure 2 As shown, this structure is used to facilitate observation of the printing process of the paper through the observation window 9.

[0032] Working principle: When using, such as Figure 1 and Figure 3 As shown, the paper is transported from the right side to the left of the protective frame 3 via the conveyor belt 2. The air pump 41 is activated, driving the pneumatic push rod 42 to lower the first fixed plate 43 and the second fixed plate 45. Figure 4 As shown, when the first fixed plate 43 descends, the rollers 53 on both sides contact the paper surface. Under the action of the first connecting rod 52 and the positioning block 51 rotating connection, the rollers 53 drive the first connecting rod 52 to rotate outward, so that the rollers 53 move along the paper to smooth the paper. The second connecting rod 544 is rotatably connected to the first connecting rod 52, pulling the second connecting rod 544 to rotate outward. At the same time, the bottom of the connecting ring 542 contacts the conveyor belt 2 and moves upward along the hole of the positioning block 51, squeezing the first spring 543. Then, the printing plate 46 presses the paper. When printing is performed on the surface, the second movable rod 62 moves along the movable groove 61 when the printing plate 46 contacts the paper. At the same time, the damping spring 63 is compressed and deformed. Under the rebound action of the damping spring 63, the printing plate 46 is reset to avoid uneven paper thickness. When the printing is completed and the plate rises, the first spring 543 pushes the connecting ring 542 and the first movable rod 541 to descend along the hole of the positioning block 51, restoring the first movable rod 541 to its original position and causing the two sets of second connecting rods 544 to pull the first connecting rod 52 to reset.

[0033] When the range of motion of the printing plate 46 needs to be adjusted, the rotating adjusting rod 66 drives the positioning plate 65 to descend along the movable groove 61, which compresses the second spring 64, thereby controlling the range of motion of the second movable rod 62. The above is the complete working principle of this utility model.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
