Conveying and paper-pressing device used for variable-diameter printing equipment

Abstract

The invention provides a conveying and paper-pressing device used for variable-diameter printing equipment, and relates to the technique field of printing. The device includes a conveying platform, the two sides of the conveying platform are rotationally connected with output shafts, the outer sides of the output shafts are fixedly connected with motors, the middles of the output shafts are fixedly connected with electric-magnetic devices, and the outer sides of the output shafts are provided with limiting grooves. According to the conveying and paper-pressing device used for the variable-diameter printing equipment, the limiting grooves and idler wheels cooperate in use, when the paper-pressing device is used, the output shafts are driven through the motors to rotate, the limiting groovesalso rotate, the positions of the idler wheels are changed, moving blocks are thus driven to stretch out and draw back, the maximum outer diameters of compression rollers are thus changed, the distance between the outer side of each compression roller to the conveying platform is changed, the moving blocks can support rubber rings to make the surface friction coefficients increase, the diametersof the compression rollers are thus changed, paperboards different in thickness are effectively and tightly pressed, the conveying efficiency is improved, and the steady operation of the conveying device is guaranteed.

Description

technical field

[0001] The invention relates to the technical field of printing, in particular to a conveying platen device for variable-diameter printing equipment. Background technique

[0002] Printing is to print text, patterns or specific information on paper, plastic and other printed matter by means of ink printing or embossing, so as to leave specific information on the printed matter, increase the recognition of the printed matter and beautify the appearance.

[0003] Most of the current paper printing is conveyed through the conveyor table. There will be a paper pressing device in the transmission table to press the paper and the conveyor belt tightly to effectively prevent slipping. Most of the current paper pressing devices have a fixed diameter, and the paper thickness of different printed products is Different, so the degree of compression of the paper will also be different, causing the paper to slip, so that the anti-skid effect cannot be achieved, resulting ...
