Front and back 32 folding pages stand-alone

Abstract

The invention discloses a front and back 32 folding single machine, comprising a frame, a folding knife mechanism installed on the frame, a transmission system and a paper feeding mechanism, the paper feeding mechanism is connected with the transmission system and is located under the folding knife mechanism , the paper feeding mechanism includes a U-shaped inner feeding belt and a J-shaped outer paper belt. The edge is placed on the periphery of the bending edge of the U-shaped inner paper belt, and the front folding input port is formed between the straight edge of the J-shaped outer paper belt and the lower straight edge of the U-shaped inner paper belt. The single folding machine has the advantages of low cost, low failure rate, and can greatly improve folding precision and quality.

Description

Technical field [0001] The present invention mainly relates to the field of printing equipment, in particular to a single machine with front and back 32-fold folding. Background technique [0002] In the prior art, when folding the paper forward and backward, two folding methods are generally used. One is to set up two sets of folding knife mechanisms on both sides of the paper to fold the paper forward and backward respectively. The folding machine adopting this structure needs to be equipped with two sets of independently operating folding knife mechanisms. When one of the folding knife mechanisms is working, the other folding knife mechanism needs to be shut down to avoid it, so the entire front and back folding process must be carried out continuously The start-stop switching of the two sets of folding knife mechanisms, on the one hand, greatly increases the manufacturing cost of the whole machine, on the other hand, the failure rate of the whole machine is high, and the main...

Problems solved by technology

The folding machine with this structure needs to be equipped with two sets of folding knife mechanisms that operate independently. When one of the folding knife mechanisms is working, the other set of folding knife mechanisms needs to be stopped to avoid, so the entire front and back folding process must be carried out continuously. The start-stop switching of the two sets of folding knife mechanisms, on the one hand, greatly pushes up the manufacturing cost of the whole machine, on the other hand, the failure rate of the whole machine is high, and its maintenance cost is also very high

Another folding method is to use a set of folding knife mechanism to fold the front side of the paper first, then turn the folding knife mechanism to the reverse side of the paper, and then fold the paper back. The folding machine with this structure, although One set of folding knife mechanism is reduced, and there is no need to switch between the start and stop of two sets of folding knife mechanisms. However, since this set of folding knife mechanisms needs to switch between two positions, a set of steering mechanisms must be equipped. After use, there will be an error in the direction of rotation, resulting in a deviation in the folding position of the front and back, which greatly affects the folding accuracy and quality of the paper
