In the prior art, the paper to be folded is automatically folded at the folding line after being input into the folding mechanism through the paper swinging mechanism. The paper is continuously conveyed and folded continuously by swinging left and right. However, in the folding process of the prior art, due to the difference in the processing of the folding lines, the folding effect of the paper at the folding line is different, and the paper cannot be folded completely, so that the folded paper is irregular or even cannot be folded completely.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] A plurality of clamping wheels are fixedly mounted on the transverse transmission shaft along its axial direction, and the plurality of clamping wheels are arranged at equal intervals. The clamping wheels include a semicircular pressure plate protruding from the circumference thereof.

[0009] Furthermore, the folding mechanisms are used in pairs side by side, and the paper is input from the paper swinging mechanism between the two, and the pressing wheel of each folding mechanism presses the folded end on the lower side thereof.

[0010] Furthermore, the driving device includes a power output shaft rotatably arranged on the upper ends of the two wall panels, a second synchronous wheel is fixed to one end of the power output shaft, a third synchronous wheel is fixed to the transverse transmission shaft, and the second synchronous wheel and the third synchronous wheel are driven by a synchronous belt.

[0011] Furthermore, it also includes two spiral wheels, which are respectively placed on both sides of the transverse transmission shaft, and the plurality of clamping wheels are located between the two spiral wheels, and the two spiral wheels are axially vertically arranged.

[0012] Furthermore, a vertical transmission shaft is fixedly mounted on the upper end of the spiral wheel, the lower end of the vertical transmission shaft is fixedly connected to the spiral wheel, a passive bevel gear is mounted on the upper end, an active bevel gear is mounted on the power output shaft, and the active bevel gear cooperates with the passive bevel gear in transmission.

[0014] Furthermore, a plurality of vertically arranged baffles are fixed on the support plate, and the baffles block the outer ends of the folded paper.

[0015] Compared with the prior art, the utility model has the following advantages after adopting the above technical solution:

[0026] The folding mechanisms are used in pairs side by side. Figure 3 As shown, the paper is input from the paper swinging mechanism between the two, and the pressing wheel 13 of each folding mechanism presses the folded end on the lower side thereof.

[0027] The driving device includes a power output shaft 3 rotatably arranged at the upper ends of the two wall panels 1, a second synchronous wheel 4 is fixed to one end of the power output shaft 3, a third synchronous wheel 5 is fixed to the transverse transmission shaft 12, the second synchronous wheel 4 and the third synchronous wheel 5 are driven by a synchronous belt, a first synchronous wheel 8 is fixed to the other end of the power output shaft 3, the external driving force is transmitted to the power output shaft 3 through the first synchronous wheel 8, the power output shaft 3 transmits the power to the transverse transmission shaft 12 through the synchronous belt, and the transverse transmission shaft 12 drives the clamping wheel 13 to rotate.

[0028] The utility model further comprises two spiral wheels 11 , which are respectively placed on both sides of the transverse transmission shaft 12 , and a plurality of pressing wheels 13 are located between the two spiral wheels 11 , and the two spiral wheels 11 are axially and vertically arranged.
