A double-sided printing device

Abstract

The invention discloses a double-sided printing device. The double-sided printing device comprises a motor, a bracket, a press printing component and a guide roller component, wherein the bracket comprises a horizontal bottom plate, as well as a first vertical plate and a second vertical plate vertically arranged; the motor is horizontally mounted on the first vertical plate; the output end of the motor is connected to a camshaft of the press printing component; the other end of the camshaft is fixed to the second vertical plate; a cam is arranged on the camshaft and is cooperatively mounted with two rolling bearings; the rolling bearings are mounted on a main body; the main body is rhombic; the upper end of the main body is hinged to an upper connection rod, and the lower end of the main body is hinged to a lower connection rod; the upper connection rod is hinged to an upper fixing block; the lower connection rod is hinged to a lower fixing block; the main body is mounted on a main body shaft; the main body shaft is fixed to the first vertical plate and the second vertical plate; the bottoms of the upper fixing block and the lower fixing block are connected to a lower press printing block and an upper press printing block. Through the double-sided printing device, the manner of conveying printing substrates through a plurality of bent conveying rollers is eliminated; meanwhile, the double-sided printing effect is achieved; the printing quality is improved.

Description

Technical field: [0001] The invention relates to the technical field of printing machinery, in particular to a double-sided printing device. Background technique: [0002] In the printing industry, sometimes it is necessary to print the front and back of the printing substrate at the same time, but sometimes the operating space is small, and the bag needs to be re-threaded during the conversion, which takes a long time and affects work efficiency. Printing is carried out on both sides of the front and back of the space, and the printed matter is easy to wrinkle and it is difficult to ensure product quality. To solve the above problems, the application number is CN201220655145.1. The drying equipment, the printing device on the other side of the printing, the second drying equipment, the first drying equipment and the second drying equipment have a double-layer structure with one upper and one lower. The above-mentioned mechanisms are all set on the body; the printed substrat...

Problems solved by technology

[0002] In the printing industry, sometimes it is necessary to print the front and back of the printing substrate at the same time, but sometimes the operating space is small, and the bag needs to be re-threaded during the conversion, which takes a long time and affects work efficiency. Printing is carried out on both sides of the front and back of the space, and the printed matter is easy to wrinkle and it is difficult to ensure product quality. To solve the above problems, the application number is CN201220655145.1. The drying equipment, the printing device on the other side of the printing, the second drying equipment, the first drying equipment and the second drying equipment have a double-layer structure with one upper and one lower. The above-mentioned mechanisms are all set on the body; the printed substrate is conveyed The mechanism sends the printing device to print one side for printing on one side, and dries the first side of the printed substrate through the first drying equipment, and then prints the other side through the printing device that prints the other side, and then passes through the second drying equipment Dry the other side of the substrate to be printed; after drying, it is output to the next process synchronously by the transmission mechanism

However, the present invention still requires a longer substrate length, and the substrate will inevitably slip and deviate when passing through several driving rollers, which will affect the processing quality
