At this time, the right paper is transferred to the upper end surface of the previous sheet, and the pressing plate 142 Slide down and press the second sheet of paper. At this time, the left main gear 137 drives the left helical gear 201 to rotate, so that the left transmission gear 215 rotates, and the left transmission gear 215 rotates to push the left pendulum The plate 213 rotates, the left swing plate 213 drives the left power rack 207 to slide, and the left power rack 207 drives the left driven gear 214 to rotate, so that the left swing lever 210 moves the paper After folding, the pressing plate 142 slides up.

Repeat the above steps to realize the folding and folding of the paper. At the same time, the long rod 108 rotates to drive the threaded block 117 moves close to each other, so that the pressing block 144 slowly moves down, so that the pressing plate 142 always maintains the same pressing force on the paper. When the paper stack 105 is folded, the pressing block 144 At the lower limit position, the air cylinder 303 is activated at this time, the push plate 301 pushes the upper end surface of the pressure block 144 to fold, and the paper passes through the connecting cavity 146 to the outer space. At this time, the torsion spring 127 reaches its maximum torque. The rotating motor 140, the rotating motor 124, and the air cylinder 303 stop working, the torsion spring 127 pushes the rack 132 to slide up, and the fixed rod 1 links the gear 131 and the power gear 129, and the long rod 108 Reverse rotation can move the slider 106 and the pressing block 144 to the initial position.

In the limit position, the pendulum rod is in a horizontal position, the side screw blocks are in an extreme position close to each other, and the screw blocks are in an extreme position far away from each other, so that the above structure is in the initial position in the initial state and can be used in subsequent work Make adjustments to effectively improve the coordination of equipment.
[0037] When the equipment is running, the rotating motor is started. At this time, the driving gear engages and drives the driven gear to rotate, so that the rotating column rotates, and the rotating column pushes the top rod to rotate to rotate the long rod, The side threaded blocks move away from each other through thread cooperation, thereby pushing the sliding block to move up slowly, while the long rod drives the power gear to rotate, and the power gear drives the linkage gear to rotate, The interlocking gear drives the rack to move down slowly and pushes the torsion spring, so that the torsion spring slowly accumulates torsion force, and at the same time the rotation motor works, at this time the driving bevel gear drives the main gear to rotate , The connecting rod drives the worm wheel to rotate, and then the conveying wheel rotates. At this time, the left paper stack has more paper than the right paper stack, so that there is a specified time difference between the two sides of the paper feeding, and the paper transport To the upper end surface of the friction strip, so as to avoid the phenomenon of conveying multiple sheets at a time. At this time, the left paper is conveyed to the upper end surface of the pressing block, and the pressing plate slides to the lower limit position to compress and flatten the paper, and then move up to the limit position , At this time, the right paper is transferred to the upper end surface of the previous paper, and the pressure plate slides down to compress the second paper.

At this time, the left paper stack transfers the third paper to the upper side of the folded paper, as the paper returns to the original level after folding The state takes a certain time, and at this time, the pressing plate slides down to compress the paper again. At this time, the second sheet of paper on the right starts to fold. Repeat the above steps to achieve the paper folding and folding in half. At the same time, the long rod After rotating, the threaded blocks are driven to move closer to each other, so that the pressure block slowly moves downward, so that the pressure plate always maintains the same pressing force on the paper. When the paper stack is fully folded, the When the pressure block is at the lower limit position, the air cylinder is activated, and the push plate pushes the upper end face of the pressure block to fold the paper through the connecting cavity to the external space. At this time, the torsion spring reaches the maximum torque, and the rotation The motor, the rotating motor, and the air cylinder stop working, the torsion spring pushes the rack to slide up, and through the fixed rod linkage gear and power gear, the long rod rotates in the opposite direction to move the slider and the pressure block Just go to the initial position, so that the efficient operation of the equipment is realized through the fast-returning movement mechanism, and the working efficiency of the equipment is improved.
