AI Technical Summary

Technical Problem

Existing double-marking creasing machines have stability issues when paper stably passes through two marking units, affecting the continuity and accuracy of the marking process.

Method used

Design a double-blade creasing machine, which adopts a first conveying rubber roller group and a second conveying rubber roller group. The paper passes through the first creasing unit and the second creasing unit in the creasing area. The paper guide structure and guide groove ensure stable paper feeding. The creasing units are arranged side by side and closely arranged on the middle guide rail to reduce the interval. The elastic guide plate is set to prevent paper jams.

Benefits of technology

It achieves stable paper feeding in the double-blade creasing machine, reduces paper jams, and improves the stability and accuracy of creasing work. It is suitable for both positive and negative creasing processing.

Abstract

This disclosure proposes a double-blade creasing machine. The first side plate (13) and the second side plate (14) are provided with a front guide rail (15), a middle guide rail (16) and a rear guide rail (17) arranged vertically along the paper feeding direction. A first guide groove is formed between adjacent front guide rails (15) and middle guide rails (16), and a second guide groove is formed between adjacent middle guide rails (16) and rear guide rails (17). A first upper seat (9) and a first lower seat (11) slide vertically in the first guide groove, and a second upper seat (26) and a second lower seat (28) slide vertically in the second guide groove. A first creasing unit (3) and a second creasing unit (4) are arranged side by side and adjacent to each other through the middle guide rail (16). Furthermore, a first paper guide structure is provided on the paper feeding side of the first upper blade assembly (5) and the first lower blade assembly (6), and a second paper guide structure is provided in the adjacent interval between the first creasing unit (3) and the second creasing unit (4). The double-blade creasing machine has good stability.
