[0002] The folding machine is mainly used for folding papers of various sizes and thicknesses within the designed range. It is suitable for large-scale folding of fast printing centers, production enterprises, official documents and business letters.

[0003] For example, Chinese patent application No. 202022463537.5 discloses a folding machine, which relates to the field of printing technology, including a base and a conveying platform, wherein the conveying platform is installed on the top of the base, and an intermediate frame is provided on the top of the base, and a cylinder is installed in the middle of the top of the intermediate frame. When the utility model is in use, the first motor is first started to drive the screw to rotate and drive the baffle to move. Since the screw and the baffle are connected by threads, the first motor drives the screw to rotate, which can drive the baffle to move along the direction of the scale slide bar, and the baffle can be accurately moved to the desired length, and can be viewed through the scale slide bar. When the paper needs to be creased at different places, it is only necessary to use the first motor to drive the screw to rotate and move the baffle a corresponding distance, and then use the cylinder to push the creasing knife to creasing the paper, and then fold it. In this way, the paper can be folded at different positions according to customer requirements, which also greatly improves work efficiency.

[0004] In the above scheme, the paper is not flattened after folding, which may cause wrinkles and curls on the paper, greatly affecting the quality of the folding and easily causing damage to the paper. In order to solve the above problems, we designed a folding machine that prevents paper damage. Utility Model Content

[0024] As shown in the accompanying drawings of the specification, the second conveying mechanism 6 includes an auxiliary frame 801 arranged between two support plates, and a driving shaft 803 and a driven shaft 804 are provided on the auxiliary frame 801. A transmission belt 802 is provided between the driving shaft 803 and the driven shaft 804, and the transmission belt 802 rotates around the auxiliary frame 801. The structure of the first conveying mechanism 9 is the same as that of the second conveying mechanism 6.

[0025] As shown in the drawings of the specification, the clamping mechanism 8 includes a connecting rod 812 arranged between two support plates, a connecting rod 805 is provided on the connecting rod, a connecting block 810 is provided at one end of the connecting rod 805 away from the connecting rod, a connecting shaft 808 is passed through the connecting block 810, at least two clamping rollers 806 are provided on the connecting shaft 808, side plates 813 are provided on both sides of the connecting shaft 808, a connecting shaft 809 is provided between the side plates 813, at least two clamping rollers 807 are provided on the connecting shaft 809, and in order to improve the clamping effect on the paper, the clamping rollers 806 and 807 are tangent to the conveying belt 802.

[0026] A cleaning brush 811 is provided at the bottom end of the auxiliary frame 801, and the cleaning brush 811 is tangent to the conveyor belt 802.

[0027] In actual use of the above structure, the specifications of the folded paper are adjusted according to the needs. After the adjustment is completed, the paper is placed on the first conveying mechanism 9 and moved. Under the action of the first conveying mechanism 9, the paper is partially moved to the bracket 10. When the paper contacts the contact sensor 14, the first conveying mechanism 9 stops running, the electric telescopic rod 4 moves vertically downward, the paper leaf knife 5 moves vertically downward, and the folding knife 6 folds the paper. At the same time, the paper passes through the slot 15. Under the vertical downward movement of the folding knife 5, the paper contacts the two rollers 16. Driven by the rollers 16, the paper moves vertically downward. After the pressure of the two rollers 16, the paper falls on the second conveying mechanism 18. The second conveying mechanism 18 transports the folded paper to the storage plate 7. The baffle plate 701 limits the paper to prevent it from falling.

[0028] At the same time, when the folded paper falls onto the second conveying mechanism, the pressing mechanism presses the paper again to further increase the balance of the folded paper. Specifically, in conjunction with the drawings of the specification, the pressing roller 1 806 and the pressing roller 2 807 rotate clockwise under the drive of the conveyor belt 802, and the paper passing under the pressing roller 1 806 and the pressing roller 807 is pressed again to increase the folding effect of the folded paper.
