Example one

Referring to fig. 1-3, the utility model provides a compound back die cutting structure of rubber surface printing, including base 1, material transition frame 2, rubber surface printing group 3, stoving group 4, die cutting group 5, draw group 6, surface fabric bed charge separation structure 7, surface fabric bed charge composite construction 8 and bed charge transport structure 9; the material transition frame 2, the rubber surface printing group 3, the drying group 4, the die cutting group 5 and the traction group 6 are sequentially arranged from left to right, the rubber surface printing group 3, the drying group 4, the die cutting group 5 and the traction group 6 are arranged on the upper end face of the base 1, the fabric and backing material separating structure 7 is arranged on the left end face of the rubber surface printing group 3, and the fabric and backing material composite structure 8 is arranged on the left end face of the die cutting group 5.

Please refer to fig. 1, the drying group 4 uses LED lamps to dry the ink by irradiation; further, the separated base paper interleaving tube is conveyed to the surface material and base material composite structure 8 after passing through the plurality of conveying rollers 91 and the base material tensioning structure 92, the base material tensioning structure 92 is installed and fixed on the right end face of the supporting seat of the material transition frame 2, the base material tensioning structure 92 comprises two tensioning rollers, the relative positions of the two tensioning rollers are fixed through connecting plates, and the base paper penetrates through the left side and the right side of the two tensioning rollers respectively.

The existing fabric and backing material separating structure 7 has the following defects that because the printing materials have elasticity, the elasticity of each printing material is different, and the positions of the surface paper and backing paper separating structure and the roller 72 are not adjustable, the printing materials are easy to stick on a printing plate when the offset surface is used for offset surface printing, so that overprinting is inaccurate, and the printing plate is seriously damaged;

please refer to fig. 2, we improve the separating structure 7 of the material and the substrate, and change the shaft groove 711 for installing the rotating shaft of the roller 72 into a step-type adjustable structure, which can be adjusted according to the characteristics of the printing material to achieve the ideal printing effect.

In the prior art, when the surface paper and the bottom paper are compounded, the surface paper is separated from the backing material before the glue surface is printed, and then the surface paper and the backing material are compounded unevenly due to elastic deformation or other factors, so that the subsequent die cutting process is influenced.

Please refer to fig. 3, we add a complex degree adjusting screw 81 on the fabric and bed charge complex structure to precisely adjust and control the offset direction, so that the overlap ratio of the printing fabric and bed charge reaches more than 98%, and the qualified rate of the product is improved, and the printing material is not adhered to the rear traction roller 72 to cause the shutdown for cleaning.

Please refer to fig. 1 again, a conveying roller 91, which is partially located in a groove formed at the upper end of the base 1, is fixed below the rubber surface printing group 3 and the die cutting group 5 through a bracket, and the rubber surface printing group 3 and the die cutting group 5 can move left and right through a moving hand wheel 31.

The specific operation of the first embodiment is as follows:

the printing material is conveyed to the fabric backing material separation structure 7 through the material transition frame 2 to be separated into surface paper and bottom paper, the separated surface paper is printed with patterns through the rubber surface printing group 3 and then is dried with printing ink through the drying group 4, the bottom paper is conveyed to the fabric backing material composite structure 8 through the backing material conveying structure 9 and is compounded with the dried surface paper, the compounded printing material passes through the die cutting group 5 and is subjected to die cutting on the printing material through the circular die, and the die-cut printing material is wound through the traction group 6.

The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, if the method and the technical solution of the present invention are adopted, the present invention can be directly applied to other occasions without substantial improvement, and the present invention is within the protection scope of the present invention.
