Description

Technical Field

[0001] The present invention relates to the technical field of paper turning machines, and specifically relates to a stackable paper turning machine and a paper turning method thereof. Background Art

[0002] The paper turning structure of a paper turning machine is a device used to turn a stack of papers. During the paper forming process, the papers are prone to deformation and warping due to the drying and shrinkage of glue or other reasons. Therefore, it is necessary to stack the papers in the same direction into small stacks and then place them in a stack with the front and back sides stacked, using the mutual force to avoid the warping of the paper edges and flatten them, so as to ensure the flatness of the papers. Since the paper stacking structures of most existing paper turning machines are not neatly arranged in the horizontal direction when stacking papers, it brings difficulties to the subsequent turning and stacking processes, and can only stack and store a single stack of papers, indirectly reducing the paper turning and stacking efficiency of the paper turning machine, which has a certain adverse impact on actual use.

When the restraint rod 45 can move in the restraint sleeve 46, it can prevent the pushing frame 23 from tilting when moving. When the two pushing frames 23 approach each other, they will abut and clamp the paper.

[0034] Working principle: When using this stackable paper turning machine and its paper turning method, the staff can transport the paper through an external transport device (not shown in the figure), push the paper into the paper turning box 25 after alignment, and then drive the operation of the third motor 15 to drive the active bevel gear 17 to rotate. The rotation of the active bevel gear 17 can drive the driven bevel gear 19 to rotate, and the rotation of the driven bevel gear 19 can drive the threaded rod 18 to rotate. (As in this Figure 2As shown in the figure, the thread directions of the two threaded rods 18 are opposite. Under the limiting action of the limiting plate 21 and the limiting groove 22, it is ensured that the rotation of the threaded rod 18 can drive the threaded sleeve plate 20 to move, and the movement trajectories of the two threaded sleeve plates 20 move in opposite directions, completing the movement adjustment of the push frame 23. And when the constraint rod 45 can move in the constraint sleeve 46, it can prevent the push frame 23 from tilting when moving. When the two push frames 23 approach each other, they will abut and clamp the paper, so that the staff can conduct subsequent sampling and other work on the paper. After determining the paper, the second driving motor 12 is started to drive the reversing rod 13 to rotate, and the whole turning carton 25 is turned and oriented. At the same time, the first driving motor 6 below the rear plate 28 operates. When the first driving motor 6 is started, it can drive the lead screw 7 to rotate. The rotation of the lead screw 7 can drive the nut seat 8 to move. The nut seat 8 can drive the stacking frame 9 to move up and down. And the side of the nut seat 8 can play an effect of strengthening the support. Through the setting of the sleeve rod 37 and the sleeve 36, the stable anti-tilting up and down movement of the stacking frame 9 is ensured. After the stacking frame 9 fits against the rear plate 28, the double-rod hydraulic cylinder 27 can slowly pull and open the rear plate 28, and use the approaching stacking frame 9 to collect the falling paper. And the soft pad 35 in the stacking frame 9 can reduce the pressure caused by the falling paper and the damage to the paper itself. The electric telescopic rod 29 can operate in combination with the proximity sensor on the turning carton 25, press the suction cup 30 down onto the positioning plate 31 to connect the turning carton 25 and the stacking frame 9, so as to stack the paper efficiently and accurately. And the camera 38 can monitor the stacking condition in real time.
