Paper blocking device for folding machine

Abstract

The invention relates to a paper blocking device for a folding machine. The paper blocking device for the folding machine comprises a paper blocking plate and a paper blocking wheel; the paper blocking plate is installed on the paper blocking wheel; the paper blocking wheel is rotationally installed on a first installing plate through a rotating shaft; a first supporting plate is installed on theside edge of the first installing plate; the paper blocking wheel and the first supporting plate are correspondingly installed on the two sides of the first installing plate; and the first supportingplate is provided with a supporting plate installing groove through which a supporting shaft penetrates, and the supporting shaft is fixed to the folding machine. According to the paper blocking device, by arranging the paper blocking plate and the paper blocking wheel, the height of the portion, stretching out of a conveying roller bed of the folding machine, of the paper blocking plate is determined by rotating the paper blocking wheel, and therefore the number of to-be-folded products is determined; the to-be-folded products placed on the upper portion of the conveying roller bed firstly pass through the folding machine, the to-be-folded products close to the position of the conveying roller bed are effectively blocked by the paper blocking device, in the process, the to-be-folded products cannot be damaged, the quality of the to-be-folded products can be effectively guaranteed, the folding efficiency and effect of the folding machine can be improved easily, and popularizing and applying of the folding machine in the market are facilitated.

Description

technical field [0001] The invention relates to the technical field of folding machines, in particular to a paper stopper for folding machines. Background technique [0002] Folding machine is a modern printing equipment produced with the modern printing industry. Modern printing plants usually include three processing procedures: pre-press, printing, and post-press. The main carrier medium is paper. Due to the rise of packaging printing, on other material media, Such as plastics, fabrics, leather, metal surfaces, etc. are also on the rise, but the main carrier is still dominated by paper. Printing industry processing is usually divided into book and newspaper processing and packaging processing. Folding machines are mainly used for folding paper of various sizes and thicknesses within the design range. It is suitable for high-volume printing centers, production enterprises, official documents, business letters, etc. of the fold. [0003] The folding machine is mainly comp...

Problems solved by technology

[0003] The folding machine is mainly composed of paper separation system, paper feeding system, curved parallel folding system, vertical folding knife folding system, frame, transmission system, electrical control system and post receiving system, etc. During the transportation of paper to be folded, Usually, multiple items to be folded are transported at the same time. Before folding, the multiple items to be folded need to be separated in an orderly and reasonable manner before the folded items can be folded. In order to achieve the above separation purpose, a paper stopper is usually set on the folding machine A device to separate the product to be folded from the product to be folded. The existing paper stopper usually clamps the lower half of the product to be folded, so that the upper half of the product to be folded passes through. This setting method is easy to cause damage to the product to be folded High efficiency and poor folding efficiency, which is not conducive to the use on folding machines
