The fifth plate roller 511 and the sixth plate roller 521 are arranged in front and back, and have opposite running directions, and the working surface of the fifth plate roller 511 and the working surface of the sixth plate roller 521 are respectively contacted with the front surface and the back surface of the cloth;

the fifth press roller 512 and the sixth press roller 522 are elastic rubber covered rollers, and the fifth press roller 512 and the sixth press roller 522 are rotatably connected with the frame through rotatable swing arms arranged at two ends of the fifth press roller 512 and the sixth press roller 522, and are respectively in clutchable pressing arrangement with the fifth plate roller 511 and the sixth plate roller 521;

The pivot points of the arm arms of the fifth press roller 512 and the sixth press roller 522 and the axes of the two press rollers must be in the same plane;

In the working state, the outer circles of the fifth printing roller 511, the fifth pressing roller 512, the sixth pressing roller 522 and the sixth printing roller 521 are sequentially and tangentially arranged, and the fifth pressing roller 512 and the sixth pressing roller 522 are in non-pressing arrangement; namely: the fifth press roll 512 is disposed tangentially to the sixth press roll 522, but is non-nip disposed.

The principle and beneficial effects of this embodiment are as follows: 1. the substrate (printing stock) is always coated on the surfaces of the two press rolls in the process of printing the front and back surfaces, and is driven by the two press rolls to run, so that the stretching deformation condition in the traditional printing process is avoided; 2. the too high area liquid of auxiliary agent can lead to stoving energy consumption too high, and the too low area liquid can lead to follow-up dyestuff to transfer to the cloth cover completely, because the mode of adopting two-sided printing applys the auxiliary agent, can control the area liquid of auxiliary agent application in-process through changing corresponding version roller, has overcome the problem that area liquid is high in traditional padding mode.

Because the sixth press roller 522 is pressed against the sixth plate roller 521, if the sixth press roller 522 is pressed against the fifth press roller 512 at the same time, it is necessary to ensure that the fifth press roller 512, the sixth press roller 522, and the sixth plate roller 521 are absolutely parallel, otherwise, three-point stress is easily generated, so that the pressing position between the sixth press roller 522 and the sixth plate roller 521 is unevenly stressed in the left-middle-right direction, which results in that the working fluid in the left-middle-right direction of the sixth plate roller 521 cannot be uniformly transferred onto the substrate, and a left-middle-right color difference is formed.

In order to solve the problem, the fifth press roller 512 and the sixth press roller 522 are tangentially arranged, but the fifth press roller 512 and the sixth press roller 522 are not pressed, so that the substrate is always coated on the outer circular surfaces of the fifth press roller 512 and the sixth press roller 522 in the printing process, the fifth press roller 512 and the sixth press roller 522 are driven to operate and are not stretched, and meanwhile, the left, middle and right stress uniformity of the pressed part between the sixth press roller 522 and the sixth plate roller 521 is ensured, and the left, middle and right chromatic aberration is avoided.

In order to achieve these functions simultaneously, the pressing between the fifth pressing roller 512 and the fifth printing roller 511 or/and the sixth pressing roller 522 and the sixth printing roller 521 must be achieved by adopting a swinging arm, that is, at least one pressing roller must be pressed with the corresponding printing roller by adopting a swinging arm, and the fulcrum of the swinging arm (moment arm) and the centers and axes of the fifth pressing roller 512 and the sixth pressing roller 522 must be in the same plane, so that it can be ensured that the fifth pressing roller 512 and the sixth pressing roller 522 do not interfere with each other in the lifting process of pressing, the clutch is not affected, and the pressure between the sixth pressing roller 522 and the sixth printing roller 521 is not affected.

In the actual production process, the thickness of the substrate and the diameter change of the press roller caused by the elastic deformation of the press roller should be considered, so that a proper gap is left between the fifth press roller 512 and the sixth press roller 522 for the substrate to pass through in order to avoid the pressure between the fifth press roller 512 and the sixth press roller 522, and the gap is preferably the thickness of the substrate, but the gap can be properly enlarged in consideration of assembly and machining errors.

In one application scenario of the present embodiment, the auxiliary agent applying device 500 may be one or a combination of two of an anilox roller printing device or a spraying device or a cylinder printing device or a rotary printing device or a padding device, where the auxiliary agent applying device 500 applies an auxiliary agent to the surface of the substrate, where the auxiliary agent is water, deionized water, or an aqueous solution of a fixing agent or a thickener, and the surface tension of the auxiliary agent is greater than the surface tension of the working surface of the central roller 210 and less than the surface tension of the substrate (fabric). The wetting action of the auxiliary agent may dissolve the dye that is pseudo-attached to the surface of the central cylinder 210 while increasing the surface tension of the dye, making it easier for the dye to transfer from the surface of the central cylinder 210 to the substrate surface.

In one embodiment, the reactive dye solution is first printed on the surface of the corresponding first central cylinder 210 by the second rotary screen printing module according to the pattern set by each second plate roller 231, and then heated and dried, the dye is pseudo-adhered to the surface of the central cylinder 210,

The auxiliary agent is a fixation alkaline agent, the cloth enters the auxiliary agent applying device 500 from the substrate sending device 100, the auxiliary agent applying device 500 applies the fixation alkaline agent to the cloth, the dye which is attached to the surface of the central roller 210 in a false way contacts with the fixation alkaline agent under the action of pressure at the first printing component 220, the water in the auxiliary agent solution dissolves the dye, the dye reacts with, crosslinks and combines with the cloth under the action of the fixation alkaline agent, and meanwhile, the dye which is attached to the surface of the central roller 210 in a false way is separated from the surface of the central roller 210 because the surface tension of the cloth is far greater than the surface critical surface tension of the central roller 210, and the dye is transferred onto the cloth.

In another application scenario of this embodiment, for the manner of directly printing with the intaglio plate, an elastic glue layer is required to be disposed on the surface of the central roller 210, and since the intaglio plate is a steel roller or a ceramic layer is disposed on the surface of the steel roller, the surface hardness is high, if the central roller 210 is a stainless steel or chrome-plated surface, and there is no protection of the elastic glue layer, when the intaglio plate collides with the central roller 210, the two steel rollers are hard boldly confront or challenge a powerful opponent to cause damage to the plate roller or the central roller 210, and meanwhile, because there is no elasticity, deformation generated during processing, assembly or operation cannot be compensated, and gaps exist between the two opposite-pressing rollers, so that stress of the substrate in the width direction is uneven, and the transfer effect is poor.

The transfer roller in the rotary printing assembly is a rubber covered roller, and the elasticity of the rubber covered roller can eliminate deformation among the plate roller, the transfer roller and the central roller 210 when the rubber covered roller is pressed with the steel central roller 210, so that the stress of the base material in the width direction is uniform, and the transfer effect of dye is better when the dye is transferred from the surface of the central roller 210.

The cylinder in the rotary screen printing assembly is a nickel plating cylinder, the thickness of the cylinder is very thin, the cylinder has certain elasticity, deformation between the cylinder and the central roller 210 can be eliminated, and the stress of the base material in the width direction is uniform, so that the transfer effect of dye when transferred from the surface of the central roller 210 is better, and the rotary screen printing assembly can be used for directly printing on the surface of the central roller 210.

After the central drum 210 is heated, since the surface of the central drum 210 has no coating layer, heat is more efficiently transferred from the surface of the central drum 210 to the dye or cloth on the surface of the central drum 210, so that efficient heating can be performed. Since the diameter of the central drum 210 cannot be infinitely large, the heat transfer efficiency of the central drum 210 directly affects the production efficiency of the apparatus, the satellite type double-sided printing machine of the present utility model preferably uses a stainless steel or chromed steel drum as the surface of the central drum 210, and performs sand blast, corrosion or plasma treatment on the stainless steel or chromed surface, and simultaneously, the first printing assembly 220 and the second printing assembly 230 directly print the dye on the surface of the central drum 210 or the surface of the substrate by using a rotary printing assembly transfer printing or rotary screen printing assembly.
