Automatic sheet transmission tension adjustment device and sheet post-processing system

Abstract

The invention relates to an automatic sheet transmission tension adjustment device, which is used for automatically adjusting the transmission tension force of a sheet unreeled from a sheet unreeling device and transmitted to a sheet post-processing device. The automatic sheet transmission tension adjustment device comprises a swing roller mechanism, wherein the swing roller mechanism is provided with a swing roller, a swing rod and a swing shaft; the swing roller is arranged at one end of the swing rod to do the pendulum movement around the swing shaft; the swing roller is positioned between the sheet unreeling device and the sheet post-processing device and pressed on the sheet; and the swing roller is used for swinging up or down with the change of the sheet unreeling speed of the sheet unreeling device and the sheet traction speed of the sheet post-processing device to reduce or increase the transmission stroke of the sheet between the sheet unreeling device and the sheet post-processing device so as to keep stable sheet transmission tension force in the transmission process. The invention further relates to a sheet post-processing system comprising the automatic sheet transmission tension adjustment device.

Description

technical field [0001] The invention relates to an automatic adjustment device for sheet material transmission tension and a sheet material post-processing system. Background technique [0002] The base paper needs to maintain a stable tension in the post-processing process to ensure that the base paper will not fluctuate greatly during the transmission process and affect the post-processing quality of the base paper. The tension of the base paper during the transmission process is mainly determined by the base paper unwinding speed of the unwinding device and the base paper pulling speed of the post-processing machine. [0003] In the actual production process, the unwinding speed of the base paper is not consistent with the pulling speed of the base paper, and there is a speed difference between the two. Moreover, the base paper unwinding speed and the base paper pulling speed are not always at a constant speed, so the speed difference between the base paper unwinding spe...

Moreover, the base paper unwinding speed and the base paper pulling speed are not always at a constant speed, so the speed difference between the base paper unwinding speed and the base paper pulling speed will also fluctuate

Due to the fluctuation of the speed difference between the unwinding speed of the base paper and the pulling speed of the base paper, the tension of the base paper during the transmission process cannot be kept stable and fluctuates. The state of tension cannot always be maintained during the process, resulting in production failures such as paper breakage, which not only affects production efficiency, but also has a great impact on the processing quality of base paper
