Description

Technical Field

[0001] The utility model relates to the technical field of folder machines, and particularly relates to a folder machine with a flattening device. Background Art

[0002] A folder machine is a modern printing device accompanying the modern printing industry. It is mainly used for folding papers of various different sizes and thicknesses, and is suitable for mass folding of fast printing centers, production enterprises, official documents, and business letters. The papers after being folded by the folder machine are conveyed out from the outlet of the folder machine. In the actual production process, in order to ensure that the folded papers do not warp when leaving the folder machine, a flattening device is usually arranged at the outlet position of the folder machine.

[0003] The existing Chinese patent with the application number CN202220478037.5 discloses a flattening device for a folder machine, including a folder machine body, a paper outlet, and a conveyor belt. The paper outlet is opened at the bottom of the front of the folder machine body, and both sides of the conveyor belt are fixedly connected to both sides of the inner wall of the folder machine body. A fixed plate is fixedly connected to the bottom of the front of the folder machine body, and a connecting plate is fixedly connected to the front of the fixed plate. This device can adjust the height of the flattening device according to the thickness of the folded paper to avoid paper jams at the outlet position of the folder machine. However, the distance between the two sets of rotating wheels used for flattening is fixed and cannot be freely adjusted according to the width of the folded paper. Both too small and too large distances will result in poor flattening effects.

[0004] Based on this, the utility model designs a folder machine with a flattening device to solve the above problems. Content of the Utility Model
