Description

Technical Field

[0001] The utility model relates to the technical field of paper stacking machines, in particular to a conveying device for paper stacking machines. Background Art

[0002] The conveying device used in the paper stacking machine usually adopts a conveyor belt device. The main function of this device is to convey the paper from the input end to the folding area, and convey the paper to the output end or collection area after folding. The conveyor belt device can ensure the stability and continuity of the paper during the conveying process, thereby ensuring the normal operation and efficient production of the paper stacking machine.

[0003] For example, the Chinese authorized patent "A paper loading device for a paper stacking machine" with announcement number CN220011477U includes a conveyor belt one, a lifting conveyor belt, a lifting structure, a pushing structure, a separation box, a paper feeding structure, a conveyor belt two, and stacked paper; one end of the conveyor belt one is in contact with the lifting conveyor belt, both ends of the lifting conveyor belt are fixedly connected to the lifting structure, the upper end of the lifting structure is movably connected to the pushing structure, the pushing structure is fixedly connected to the separation box away from the side of the conveyor belt one, the upper end of the separation box is fixedly connected to the paper feeding structure near the pushing structure, an empty slot is provided inside the separation box, the separation box is fixedly connected to the conveyor belt two, and stacked paper is placed above the conveyor belt one.

[0004] Although the above-mentioned prior art can realize the conveying of paper, the front end of the paper is prone to be uneven when loading, which requires manual assistance when entering the paper stacking machine. Otherwise, the paper is difficult to enter the paper stacking machine smoothly. However, manual operation is not only time-consuming and labor-intensive, but also involves operational risks. Therefore, it does not meet the existing needs. In this regard, we propose a conveying device for a paper stacking machine. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model is provided with a flattening mechanism. When the paper enters from the traction mechanism to the bottom of the flattening roller, the electric heating wire in the inner shaft of the flattening roller is turned on first to convert electrical energy into thermal energy. The heat is transmitted to the flattening roller through the rotating shaft to increase the surface temperature of the flattening roller. Then the first electric push rod is turned on to drive the lifting block equipped with the flattening roller to descend until the two flattening rollers are squeezed at the center of the paper. At this time, the first motor is turned on, and its output shaft drives the double-threaded transmission rod to rotate. Under the friction with the sliding block, the two flattening rollers are slowly moved toward the two sides of the paper in cooperation with the guiding effect of the inner cavity of the upper plate of the flattening mechanism on the sliding block. During the movement, the heat on the surface gradually softens the paper, and the squeezing of the paper by the flattening roller makes the wrinkled surface of the paper tend to be flat, so that it can smoothly enter the paper stacking machine, reducing the workload of the staff and reducing the operation risk.

[0017] 2. The utility model adopts a linkage conveying structure. When the paper is arranged, it passes between the pressure roller and the conveying roller. Under the action of the second electric push rod, the pressure roller and the paper are squeezed and fixed. At this time, the second motor is turned on. On the one hand, its output shaft drives the shaft at one end of the conveying roller to rotate, and the conveying roller is driven to move toward the flattening mechanism under the friction between the conveying roller and the paper. On the other hand, pulleys are installed on the shafts of the second motor and the transmission. The pulleys are connected through belt transmission. Then, during the rotation of the output shaft of the second motor, the input shaft of the transmission is driven to rotate through the belt. The speed is adjusted by the gear to match the conveying speed of the conveying roller to the paper, so that the unwinding wheel is driven to rotate through its output shaft to realize the unwinding of the paper. The cooperation of the two can avoid damage to the paper due to excessive traction of the conveying roller, and at the same time make the unwinding process smoother.

[0027] When the paper enters from the traction mechanism 9 to the bottom of the flattening roller 24, the electric heating wire 25 in the inner shaft of the flattening roller 24 is turned on first to convert electrical energy into thermal energy. The heat is transferred to the flattening roller 24 through the rotating shaft to increase its surface temperature. Then the first electric push rod 7 is turned on to drive the lifting block 5 equipped with the flattening roller 24 to descend until the two flattening rollers 24 are squeezed at the center of the paper. At this time, the first motor 19 is turned on, and its output shaft drives the double-threaded transmission rod 22 to rotate. Under the friction with the sliding block 23, the two flattening rollers 24 are slowly moved toward the two sides of the paper in cooperation with the guiding effect of the inner cavity of the upper plate of the flattening mechanism 4 on the sliding block 23. During the movement, the heat on the surface gradually softens the paper, and the squeezing of the paper by the flattening roller 24 makes the wrinkled surface tend to be flat.
