Printing roller for printing and capable of removing residues and achieving uniform smearing

Abstract

The invention discloses a printing roller for printing and capable of removing residues and achieving uniform smearing, and relates to the technical field of printing. The printing roller comprises aprinting roller body. The top of the printing roller body is movably connected with a mounting seat. A first electromagnet is fixedly connected to the inner wall of the right side of the mounting seat. The position, close to the first electromagnet, of the bottom of the inner top wall of the mounting seat is movably connected with a removal plate. A magnetic block is fixedly connected to the innerwall of the inner side of the removal plate. The middle of the removal plate is fixedly connected with a dielectric medium plate. By means of the printing roller for printing and capable of removingresidues and achieving uniform smearing, through cooperative use of the first electromagnet and the first magnetic block, during use, the first electromagnet is in a power-on state all the time, magnetism the same as that of the top of the first magnetic block is generated at the bottom of the first electromagnet, the first magnetic block bears acting force that like charges repel each other, theremoval plate is driven to stretch out downwards, the removal plate is attached to the outer side of a conveying roller, solidified residues on the outer side of the conveying roller are effectively removed, and therefore the effect that residues can be removed is achieved, cleanliness of the printing roller is guaranteed, and printing quality is improved.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing roller for printing that can remove residue and evenly smear. Background technique [0002] According to the different printing materials used, printing can be divided into paper printing, white iron printing, plastic printing, textile printing, wood printing, glass printing, etc. Paper printing is the mainstream of printed matter, accounting for about 95%. No matter letterpress, lithography, gravure, or stencil, it can be applied. It is solidly called ordinary printing, and printing materials other than paper are mostly special printing. [0003] The printing methods are different, and the printing equipment used is also different. Most of the current textile printing equipment uses printing rollers for printing and dyeing. In order to achieve continuous printing, although this printing method greatly improves the printing speed, some problems often occur during use...

Problems solved by technology

[0003] The printing methods are different, and the printing equipment used is also different. Most of the current textile printing equipment uses printing rollers for printing and dyeing. In order to achieve continuous printing, although this printing method greatly improves the printing speed, some problems often occur during use. For example, the printing roller will cause the dye to solidify and adhere to the On the outside of the printing roller, the printing roller is uneven, resulting in uneven smearing of the printed image, and it is difficult to clean up the attachments in time, resulting in a decline in printing quality and affecting production efficiency
