Paper type cutting folding machine

Abstract

The invention discloses a paper type cutting folding machine which comprises a type cutting mechanism and a folding mechanism which are sequentially arranged along an advancing direction of paper, wherein the type cutting mechanism is provided with a vacuum adsorption forming knife roller, a knife clamping groove which is in a same shape with a formed paper edge is arranged on a roller surface of the forming knife roller, a blade is inlaid in the knife clamping groove, a scraper matched with the blade on the forming knife roller is arranged above the forming knife roller, and a paper indentation roller matched with the forming knife roller is arranged before the scraper. According to the paper type cutting folding machine disclosed by the invention, by rotating the forming knife roller, the scraper is matched with a mold arris arranged on the scraper and does not move or carries out reciprocating motion along the axial direction of the forming knife roller so as to realize type cutting of the paper, the type cutting mechanism can cut an arbitrary irregular graph on the paper and has low requirements on the paper, and with the adoption of the type cutting mechanism, a cut is tidy, and a deckle edge does not exist; and the mold arris on the forming knife roller consists of the knife clamping groove and the blade, and the blade is only needed to be replaced after abrasion, so that the cost is greatly saved, and in addition, use is convenient.

Description

technical field [0001] The invention relates to a paper folding device, in particular to a paper cutting type folding machine. Background technique [0002] Existing paper cutting and folding machines include a cutting mechanism and a folding mechanism. The roll paper is cut into a desired shape by the cutting mechanism, and then the paper is folded into shape by the folding mechanism. The cutting mechanism includes a bottom knife roller and a cutter roller. The cutting structure of the existing cutting mechanism has two forms. 1. Press-cutting type: the surface of the bottom knife roller is used to obtain the shape of the paper by etching or engraving. Blade, the paper is spread on the bed knife roller, and the cutter roll presses the bed knife roller to cut the paper along the knife edge, so as to obtain the required paper shape; this method requires high processing requirements for the bed knife roller and costs a lot , The bed knife roller has a short service life. 2....

Problems solved by technology

The cutting mechanism includes a bottom knife roller and a cutter roller. The cutting structure of the existing cutting mechanism has two forms. 1. Press-cutting type: the surface of the bottom knife roller is used to obtain the shape of the paper by etching or engraving. Blade, the paper is spread on the bed knife roller, and the cutter roll presses the bed knife roller to cut the paper along the knife edge, so as to obtain the required paper shape; this method requires high processing requirements for the bed knife roller and costs a lot , short service life of bed knife roller

2. Missing cutting type: the knife on the bottom knife roller is an inlaid serrated knife, and there is a certain gap between the corresponding cutting knife roller and the blade, so that the purpose of cutting paper can be achieved; the processing cost of this method is Low, but the requirements for paper are high, and the cut of paper is not neat, so it is not easy to be accepted by users
