Abstract

[0002] Fiber paper bags are made of fiber paper, which is thin, soft, and easy to break. Therefore, in the automated forming process, the traction force of the fiber paper needs to be controlled within its tolerance range. In the forming process of ordinary paper bags, the unwinding and traction of the paper are synchronized. The paper can withstand the asynchronous pulling force caused by deviation, but it is not suitable for fiber paper. If the two are slightly out of sync, the fiber paper will break. In addition, fiber paper is thin and soft. During the rolling and cutting process, it lacks support and positioning and is easy to droop, resulting in low rolling and cutting accuracy.

The knife seat is installed on the outer circle of the roller. The knife die is installed on the knife seat, and the knife die is eccentrically arranged on the roller.
[0006] The first die-cutting mechanism and the second die-cutting mechanism can be adjusted to move laterally.
[0007] The lower ends of the bases of the first die-cutting mechanism and the second die-cutting mechanism are respectively provided with guide blocks, which are movably arranged on the transverse guide rail group. The lower end of the base is also provided with a driving block, which is threadedly connected with a transverse screw rod. The other end of the screw rod can be rotatably passed through the frame and is equipped with a knob.
[0008] Guide rollers are arranged at the front and rear of the first die-cutting mechanism and the second die-cutting mechanism, and a tension adjusting component is arranged between the first die-cutting mechanism and the second die-cutting mechanism.
[0009] The tension adjustment component includes an adjusting roller, and sliders are provided at both ends of the adjusting roller. The sliders can be lifted and moved and are arranged on the side beams of the gantry, and a column is threadedly connected to the slider. The upper end of the column can be rotatably passed through the cross beam of the gantry. A driving cross bar and a driving hand wheel are rotatably provided on the gantry, and the driving cross bar and the upper end of the column are connected by a bevel gear set.
[0010] The beneficial effect of the utility model is that the improved fiber paper bag forming machine is provided with multiple traction channels and cooperates with material storage to avoid unsynchronized unwinding and traction, which causes fiber paper breakage, thereby realizing stable and reliable traction transmission of fiber paper; the rolling and cutting mechanism adopts a vacuum adsorption roller to position the fiber paper, so as to realize the precise cutting of the fiber paper by the knife roller assembly.
