[0034] Please also read Figures 1 to 5 Now, a fully automatic high-speed folding device provided in the embodiment of the present application is described. The fully automatic high-speed folding device includes a frame 101, a discharging conveyor belt 102, a deflection component, a material receiving component and a material cutting component. Among them:

[0035] The discharge conveyor belt 102 is arranged at the bottom of the frame 101. The deflection assembly includes a deflection shaft 103 rotatably mounted on the frame 101 and a guide roller 104 connected in parallel to the deflection shaft 103. At least two guide rollers 104 are arranged horizontally to form a material passing gap. The material receiving assembly is arranged between the discharge conveyor belt 102 and the deflection assembly. The material receiving assembly includes a material receiving plate 105 movably mounted on the frame 101 and capable of horizontal movement and a lifting platform 106 movably mounted on the frame 101 and capable of vertical lifting. The material receiving plate 105 and the discharge conveyor belt 102 are respectively provided with a plurality of gaps for the lifting platform 106 to pass through. The material cutting assembly includes a longitudinal beam 107 connected in parallel to the material receiving plate 105 and a cutting knife 108 movably mounted on the longitudinal beam 107 and capable of horizontal movement to cut the target paper sheet.

[0036] According to the above structure provided in this embodiment, when the deflection shaft 103 in the deflection assembly rotates, it can drive the guide roller 104 connected to the deflection shaft 103 to swing, so that the paper sheets passing through the adjacent guide rollers 104 can be alternately folded and stacked on the lifting platform 106 in sequence. The lifting platform 106 can continue to descend and gradually approach the discharge conveyor belt 102. When the lifting platform 106 passes through the interval on the discharge conveyor belt 102, the paper stacks placed on the lifting platform 106 will be transferred to the discharge conveyor platform and conveniently transferred and transported by the discharge conveyor platform. Before the paper stacks are transferred to the discharge conveyor platform, the horizontally movable receiving plate 105 can be inserted between adjacent folding pages and used to temporarily hold the subsequent stacks of paper. The cutting knife 108 movably installed on the receiving plate 105 can be used to cut the connected paper sheets along the dotted line position and enable the paper stacks to be transported at a preset height. After the paper stack is sent away by the discharge conveyor, the lifting platform 106 can rise again and pass through the receiving plate 105 to transfer a portion of the paper stack temporarily stored on the receiving plate 105 to the lifting platform 106 and repeat the above process. Therefore, the fully automatic high-speed folding device provided in this embodiment not only has the technical effect of automatically stacking multiple pages, but also the stacking process can be carried out continuously without stopping or slowing down, which significantly improves the folding efficiency and is far superior to the prior art.

The plug plate 109 and the receiving plate 105 are spaced apart along the height direction of the frame 101 and are located on opposite sides of the target paper sheet. The plug plate 109 is closer to the discharge conveyor belt 102 than the receiving plate 105. According to the above structure provided in this embodiment, when the cutting knife 108 cuts the target paper sheet, the plug plate 109 can move horizontally and cooperate with the receiving plate 105 to abut on opposite sides of the target paper sheet, so that the target paper sheet can be cut more smoothly along the point breaking line position (that is, the folding line position), which is conducive to further improving the folding efficiency of the fully automatic high-speed folding device in this embodiment.

[0038] In another embodiment of the present application, please refer to Figures 1 to 5 The material receiving assembly further includes a plate inserting cylinder 110 which is transmission-connected to the plate inserting 109, a material receiving cylinder 111 which is transmission-connected to the material receiving plate 105, and a material cutting cylinder 112 which is transmission-connected to the cutting blade 108.

According to the above structure provided in this embodiment, the lifting rail 114 is conducive to improving the lifting stability and lifting speed of the lifting platform 106, thereby further improving the folding efficiency of the full-automatic high-speed folding device in this embodiment. It can be understood that the driving device for driving the lifting platform 106 to rise and fall can adopt the screw nut transmission mechanism driven by the servo motor of the prior art or other linear driving mechanisms of the prior art.
