[0017] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0018] Embodiment 1:

[0019] Depend on Figure 1 to Figure 2The utility model includes a support frame 1, a conveying platform 2 is arranged in the support frame 1, a guide groove 3 is arranged at the left end of the conveying platform 2, a first belt roller 4 is arranged between the guide groove 3 and the conveying platform 2, a first conveyor belt 5 is installed on the first belt roller 4, the first conveyor belt 5 passes through the lower side of the conveying platform 2, the first belt roller 4 and the upper side of the conveying platform 2 in sequence, and the printed matter falling on the guide groove 3 can be conveyed to the conveying platform 2 through the first belt roller 4, an eccentric block 6 rotatably installed on the support frame 1 is arranged between the conveying platform 2 and the support frame 1, and a A second belt roller 7 is located on the upper side of the conveying platform 2, and a second conveyor belt 8 is installed on the second belt roller 7. The part of the second conveyor belt 8 and the part of the first belt roller 4 located on the upper side of the conveying platform 2 are parallel to the plane on the upper side of the conveying platform 2. The printed matter can be conveyed backward by cooperating with the first conveyor belt 5 and the second conveyor belt 8 on the upper side of the conveying platform 2. The distance between the second belt roller 7 and the conveying platform 2 can be adjusted by rotating the eccentric block 6, thereby ensuring that the first conveyor belt 5 and the second conveyor belt 8 do not affect the ink on the printed matter while being able to drive the printed matter to move.

[0020] The guide groove 3 is also provided with an arc-shaped guide claw 9 , which is close to the printing roller of the previous process, so that the printing roller falls on the guide groove 3 through the guide claw 9 after printing the printed matter.

[0021] A connecting frame 10 is also provided at the upper end of the conveying platform 2, and a first tensioning mechanism 11 and a second tensioning structure 12 are respectively provided on the connecting frame 10 and on the lower side of the conveying platform 2, and the first conveyor belt 5 and the second conveyor belt 8 are respectively installed on the first tensioning structure and the second tensioning structure 12, and the first tensioning mechanism 11 and the second tensioning structure 12 can be tensioning wheels.

[0022] In order to adjust the angle of the eccentric block 6 and keep the eccentric block 6 at a corresponding angle, a bolt 13 is threadedly installed on the lower end surface of the support frame 1. The bolt 13 is located on the lower side of the eccentric block 6, and the peripheral side surface of the eccentric block 6 fits with the upper end of the bolt 13 under the action of gravity.

[0023] Embodiment 2:

[0024] Depend on Figure 3 It is given that the bolt 13 is used to position the eccentric block 6. Since the eccentric block 6 will generate friction with the upper end of the bolt 13 when rotating, this will cause wear of the eccentric block 6 and the bolt 13, thereby affecting the life of the adjustment mechanism and the adjustment accuracy. The lower end of the support frame 1 is provided with a mounting frame 14, and a vertical straight rod 15 is rotatably mounted on the mounting frame 14. An eccentric wheel 16 located at the lower side of the eccentric block 6 is also rotatably mounted on the support frame 1. A worm gear 17 is coaxially mounted on the eccentric wheel 16, and a worm 18 meshing with the worm gear 17 is provided at the upper end of the straight rod 15.

[0025] The lead angle of the worm 18 is smaller than the equivalent friction angle of the worm wheel 17, so that the worm wheel 17 and the worm 18 have self-locking properties.

[0026] When the staff rotates the bolt 13, the bolt 13 receives pressure from the eccentric block 6, which makes it difficult to rotate the bolt 13, making the work difficult. The lower end of the straight rod 15 extending out of the support frame 1 is equipped with a rotating wheel 19, the diameter of the rotating wheel 19 is larger than the straight rod 15, and a rotating handle 20 is also installed on the rotating wheel 19.

[0027] When the utility model is in use, the printed matter that has completed printing leaves the printing roller and falls onto the guide groove 3 through the guiding claw. Then, the rotation of the first belt roller 4 can drive the printed matter to move to the right through the first conveyor belt 5. When part of the printed matter moves to the conveying platform 2, the second conveyor belt 8 on the second belt roller 7 contacts the printed matter. The staff can turn the bolt 13 or turn the handle 20 to adjust the rotation angle of the eccentric block 6, so as to adjust the distance between the second belt roller 7 and the conveying platform 2 and the first conveyor belt 5. The specific distance can be adjusted according to the staff's calculation, or it can be directly tested on the first printed matter until it is adjusted to a suitable height.

[0028] The beneficial effects of the utility model are as follows: the utility model has a novel structure and an ingenious conception. The first belt roller and the second belt roller drive the first conveyor belt and the second conveyor belt to move the printed matter, and the height of the second belt roller is adjusted by a bolt or a worm gear mechanism. It can meet the needs of printed matters of different sizes or types, and can also ensure the uniform transmission of ink and the clarity and accuracy of printed matters, reduce the burden on operators, and reduce human errors.
