Printing machine for back flocked sand paper

Abstract

The invention provides a printing machine for back flocked sand paper. The printing machine sequentially comprises a feeding mechanism, a printing mechanism and a winding mechanism in the advancing sequence of the sand paper and further comprises guide rollers; the feeding mechanism comprises a feeding rack and a feeding shaft; the printing mechanism comprises a printing rack, an ink duct support, an ink duct and a printing piece; the winding mechanism comprises a winding rack, a winding motor and a winding shaft; and the guide rollers are distributed between the feeding mechanism and the printing mechanism and between the printing mechanism and the winding mechanism. With the printing machine, efficient and stable printing can be performed under the condition that the use performance of the back flocked sand paper and back flocked sand cloth is not affected; an ink transfer roller is added, so that clear printing can be guaranteed, and meanwhile, reduction of the printing quality due to relatively much ink can be avoided; the drying efficiency after printing is completed can be remarkably improved, and thus the overall printing quality can be guaranteed; and the printing machine is novel in structure and suitable for popularization and use.

Description

technical field [0001] The invention belongs to the field of printing equipment, and in particular relates to a fleece-backed sandpaper printing machine. Background technique [0002] Sandpaper is usually made of base paper glued with various abrasive grains, and is used to grind the surface of metal and wood to make the surface smooth and clean. At present, the sandpaper is mainly formed by the fleece backing process and then adhered to electric or pneumatic tools. After the backing treatment, the strength of the paper is low and brittle. If you need to print trademarks and patterns on the fleece sandpaper , not only is the operation more difficult, but it is also easy to cause short paper and sand loss, which will not only affect its appearance, but also lead to a decline in its performance. [0003] Therefore, developing a kind of printing equipment that is used for back pile sandpaper is the difficult problem that those skilled in the art urgently need to solve in view ...
