[0053] The first vertical moving modules 2 are a pair, and are disposed on opposite sides of the chassis 10 along the length direction of the chassis 10. The first vertical moving modules 2 are located between the pair of vertical guide rails 101 on the same side, that is, the first vertical moving modules 2 are disposed on the chassis 10 and spaced apart from the pair of vertical guide rails 101. The horizontal moving module 1 is also connected to the first vertical moving modules 2 on the same side.

[0054] Both ends of the first movable column 3 are respectively connected to the horizontal moving modules 1 on both sides.

[0055] Under the above-mentioned design, the stacking structure of the present application is symmetrical on both sides of the longitudinal direction of the chassis 10. This structure is beneficial for maintaining the synchronization and accuracy of movement in the high-speed and precise paper towel stacking process. At the same time, the first vertical movement module 2 and the vertical guide rail 101 on the same side of the stacking structure are spaced apart on the chassis 10. The horizontal movement module 1 simultaneously connects the first vertical movement module 2 and the pair of vertical guide rails 101. The first movable column 3 is mounted on the horizontal movement module 1, thereby integrating the mechanism that drives the movement of the first movable column 3 into a single location. This layout is not only more compact, but also improves the stability of the horizontal movement module 1.

[0057] One of the first vertical movement modules 2 further includes a first driving mechanism 24 and a first synchronous rotating shaft 25. The first driving mechanism 24 is disposed on the chassis 10 and is in transmission connection with the first synchronous rotating shaft 25. Specifically, the first driving mechanism 24 is a motor.

[0058] The length direction of the first synchronous shaft 25 extends along the length direction of the chassis 10; the two ends of the first synchronous shaft 25 are respectively coaxially connected to the second synchronous wheels 22 of a pair of first vertical moving modules 2; of course, other transmission components are provided between the motor and the first synchronous shaft 25, and between the first synchronous shaft 25 and the second synchronous wheel 22, and they are all components commonly used by technical personnel in this field.

[0059] Specifically, the horizontal movement module 1 includes a mounting seat 11, a mounting plate 12 and a swing arm 13;

[0060] The length direction of the mounting plate 12 extends along the width direction of the chassis 10, and the mounting plate 12 is slidably connected to the pair of vertical guide rails 101.

The first movable column 3 is slidably connected to the horizontal guide rail 102. Similarly, the horizontal guide rail 102 is also provided with a sliding block, and the first movable column 3 is fixed to the sliding block of the horizontal guide rail 102. Under the above layout, there is a certain distance between the mounting plate 12 and the chassis 10.

The mounting plate 12 can be removed or removed separately, and the process has almost no impact on the first vertical movable module 2, which is convenient for adjustment, replacement or maintenance. At the same time, the first movable column 3 is a floating design, which facilitates adjustment of other components (cutting, folding, suction, etc.) in the chassis 10 after removal.

The actuating end is hinged to one end of the connecting member 132, the other end of which is hinged to the fixed member 133. The fixed member 133 is fixedly connected to the first movable column 3. With this design, when the second synchronous shaft 15 rotates, it drives the actuating end of the swinging member 131 to rotate, and then the connecting member 132 pushes forward or pulls back the fixed member 133, thereby driving the first movable column 3 to slide along the horizontal guide rail 102.

Under the above preference, the motor is located between the connecting plate 141 and the mounting plate 12, and the length direction of the motor extends along the length direction of the chassis 10, that is, the motor is arranged horizontally to the ground. Compared with the arrangement of the motor perpendicular to the ground, this arrangement can further utilize the space inside the chassis 10 to make room for other components (cutting, folding, suction and other structures) located on the upper part of the chassis 10;
