Double-sided printing machine

Abstract

The invention discloses a double-sided printing machine. The double-sided printing machine comprises an upper printing assembly, a lower printing assembly and a transfer roller, wherein the upper printing assembly is provided with an upper printing roller and an upper scraper; the upper scraper is obliquely abutted against the upper printing roller; an upper ink tank is defined between the upper scraper and the upper printing roller; the lower printing assembly is provided with a lower printing roller, a lower scraper and a lower ink tank; the lower scraper is obliquely abutted against the lower printing roller; the lower ink tank is arranged below the lower printing roller; the transfer roller is positioned between the upper printing roller and the lower printing roller; the upper printing roller, the transfer roller and the lower printing roller are arranged in parallel and tangentially during working; the transfer roller is used for transferring a pattern on the lower printing roller to the reverse side of an object to be printed; the upper printing roller and the transfer roller can be used for clamping the object to be printed in the middle and printing the front side and the reverse side of the object to be printed at the same time; the transfer roller is a rubber roller with elastic surface; and the radius of the upper printing roller is equal to that of the lower printing roller and is equal to the working radius of the transfer roller.

Description

technical field [0001] The invention relates to the field of printing machines, in particular to a double-sided printing machine. Background technique [0002] A printing machine is a machine that uses dyes or pigments to print patterns on textiles to be printed. At present, the main printing machines in the textile industry include rotary screen printing machines, flat screen printing machines and roller printing machines. The roller printing machine engraves the negative (or positive) pattern on the copper roller or the chrome-plated roller. Printing effect machines, roller printing machines in the prior art, are usually single-sided printing machines. When the object to be printed requires double-sided printing, it is necessary to print on the other side after printing on one side of the object to be printed, and If the double-sided patterns are different, different printing rollers need to be replaced for printing, which will consume a lot of time, resulting in prolonge...

Problems solved by technology

The roller printing machine engraves the negative (or positive) pattern on the copper roller or the chrome-plated roller. Printing effect machines, roller printing machines in the prior art, are usually single-sided printing machines. When the object to be printed requires double-sided printing, it is necessary to print on the other side after printing on one side of the object to be printed, and If the double-sided patterns are different, different printing rollers need to be replaced for printing, so it will take a lot of time, resulting in prolonged working hours and low efficiency.
