Problems solved by technology

[0006] This layout method, although there is no variable guide roller in the two printing mechanisms, avoids the defects of the first solution to a certain extent, but this solution also has disadvantages: first, the two printing mechanisms are set in alignment, and the flexible fabric In the middle of the spraying direction of the two printing mechanisms, due to different flexible fabrics, the thickness will be different. When different flexible fabrics pass through the two printing mechanisms, the spraying distance between the flexible fabric and the two printing mechanisms will change, and adjust After adjusting the spacing of one printing unit, it will naturally affect the spacing of the other printing unit. That is, when facing flexible fabrics with different thicknesses, it may be necessary to readjust the spacing between the two printing mechanisms. This is very complicated and difficult. controlling
Secondly, since the flexible fabric is dried at the same time after passing through the two printing mechanisms, the linear stroke of the drying needs to be long enough, otherwise if it is transferred to the turning guide roller, the undried pattern will adhere to the Turning to the guide roller, so for the second solution, the linear stroke of drying is long, which will increase the volume of the equipment, and at the same time, it is difficult to adjust the flexible fabrics of different thicknesses

Abstract

The invention discloses double-sided printing equipment with accurate positioning, and belongs to the field of double-sided alignment printing equipment. The double-sided printing equipment comprises a first printing unit and a second printing unit, the first printing unit and the second printing unit are used for printing same patterns on the front face and the back face of a flexible fabric correspondingly, the spraying direction of the first printing unit and the spraying direction of the second printing unit intersect to form an included angle, only one turning guide roller is arranged between transmission paths of the first printing unit and the second printing unit, the contact face of the turning guide roller is the back face of the flexible fabric, after the flexible fabric is output from the first printing unit, the transmission direction of the flexible fabric is changed through the turning guide roller, the flexible fabric enters the second printing unit, and a first drying oven for drying the front surface of the flexible fabric is further arranged on the transmission path between the first printing unit and the second printing unit. The invention further discloses a control method of the double-sided printing equipment. The double-sided printing equipment has the advantages that on the condition that the alignment precision of double-sided printing is kept good, adjustment and alignment can be easier.

Description

【Technical field】 [0001] The invention relates to a double-sided printing device with precise positioning, belonging to the field of double-sided printing devices. 【Background technique】 [0002] With the development of society and the progress of science and technology, printing equipment has become an indispensable product in daily life and office. At present, most of the printing equipment are office printing equipment, such as printing single-page paper, etc., but there are some Some printing needs to print double-sided printing equipment that can be aligned and overlapped on flexible fabrics. For this type of double-sided printing equipment, there are currently many open prior technologies, such as: [0003] In the printing equipment disclosed in the patent CN109823060A and the single-sided and double-sided printing method using the printing equipment, it is disclosed that it includes two printing mechanisms, and the two printing mechanisms are designed side by side. M...
