Description

An automatic paper delivery device for a folding machine

technical field

The utility model relates to the technical field of printing equipment, in particular to an automatic paper receiving device of a folding machine.

Background technique

Folding machine is a modern printing equipment produced along with the modern printing industry. Folding machine is mainly used for folding paper of various sizes and thicknesses within the design range. It is suitable for high-speed printing centers and production enterprises for large quantities of official documents and business letters. folding. In industrial production, the folding machine is required to work at a high speed, so the paper transmission is required to be fast, but because the paper is light, it is easily affected by the airflow during high-speed transmission and floats up, resulting in unstable transmission.

In response to the above problems, the Chinese patent with the patent announcement number CN207632225U proposes an automatic folding machine, which includes a body, a paper feeding mechanism sequentially arranged on the body, a first paper feeding mechanism, a first folding mechanism, and a second feeding mechanism. A paper mechanism, a second folding mechanism and a paper delivery mechanism, the first paper feeding mechanism includes a conveyor belt arranged on the body, the second paper feeding mechanism includes a plurality of conveyor rollers arranged on the body, the conveyor belt and A mounting plate is arranged above the conveying roller along the paper conveying direction, and a plurality of ball holes are arranged at intervals in the length direction of the mounting plate, and balls that can roll on the surface of the paper are placed in each of the plurality of ball holes.

The above-mentioned existing technical solutions have the following defects: the automatic folding machine is provided with mounting plates in the first paper feeding mechanism and the second paper feeding mechanism, and roller balls that can roll on the surface of the paper are placed on the mounting boards to press the paper. This prevents the paper from flying up due to high-speed conveyance, thereby improving the stability of paper conveyance. However, the paper delivery mechanism of the automatic folding machine does not sort the folded paper, and the paper on the paper delivery conveyor belt needs to be manually folded and sorted later, which wastes manpower and reduces paper delivery efficiency.

Utility model content

The purpose of the utility model is to provide an automatic paper delivery device of a folding machine that can automatically stack and align paper to save manpower.

The utility model is achieved through the following technical solutions:

An automatic paper delivery device for a folding machine, comprising a paper delivery mechanism and a paper delivery mechanism, the paper delivery mechanism includes a paper loading platform and four first limit plates arranged around the center of the paper loading platform, each Each of the first limiting plates is provided with two second limiting plates, and each of the first limiting plates and the two second limiting plates constitute a U-shaped frame for limiting the paper. The bottom of the paper loading table is provided with a driving assembly for driving the paper loading table to rotate on its own central axis.
