Printing roller pressure self-adjusting printing equipment for paper bag printing

Abstract

The invention relates to the technical field of paper bag printing, and discloses printing roller pressure self-adjusting printing equipment for paper bag printing. The equipment comprises a bracket, a rotating shaft is fixedly connected to the inner wall of the middle of the bracket, a magnetic block is fixedly connected to the inner wall of the middle of the rotating shaft, a non-magnetic material is fixedly connected to the inner wall of the middle of the rotating shaft, and a printing roller is movably connected to the outer side of the rotating shaft. A pressure shaft is movably connected to the outer side of the bracket, and a cushion block is fixedly connected to the outer side of the pressure shaft. According to the equipment, a paper feeding wheel drives a telescopic rod to move, the telescopic rod drives a sliding rheostat to move, an electromagnet, a fixed rod and the pressure shaft are used in cooperation, so that the effect of automatically adjusting the distance between the printing roller and a paper bag is achieved, and the paper feeding wheel is extruded to drive the telescopic rod to move outwards. At the moment, a conductive column is in contact with the sliding rheostat, and the resistance changes of the sliding rheostat are different according to different paper bag thicknesses, so that the distance between the cushion block and the printing roller is adjusted.

Description

technical field [0001] The invention relates to the technical field of paper bag printing, in particular to a self-adjusting roller pressure printing device for paper bag printing. Background technique [0002] With the improvement of environmental protection awareness, the society will reduce the use of plastic bags more and more. Due to the pollution of plastic bags, it is difficult to decompose. Instead, paper bags or cloth bags are used instead of plastic bags to protect the environment. Due to the cost of cloth bags More expensive, and portable paper bags are widely used because of their low cost, convenient use, and more environmental protection. [0003] In order to make the paper packaging bags more aesthetically pleasing, the distance between the printing roller and the paper needs to be constantly adjusted for printing on paper bags of different thicknesses. If the distance is too short, it may lead to excessive printing and waste of ink. If the distance is too lar...
