In order to bring a better printing experience to customers and at the same time improve its own competitiveness, Fedar Textile Printing has been working silently, constantly developing and upgrading printing technology, and improving the printing accuracy of digital printing machines. Recently, Fedar has made another breakthrough in the step accuracy of the paper platen roller. At present, the stepping accuracy of the platen roller has been improved by more than 50%.

When the digital printing machine is printing, the paper is prone to low pressure in the transmission part, unbalanced pressure, and excessive local pressure, which leads to changes in the paper feeding accuracy, and eventually leads to problems in the quality of the printing step of the equipment, resulting in the transfer of finished products. Problems such as poor local accuracy, regular horizontal bars or blurred images. At present, there are many transmission schemes for this type of equipment on the market, such as belt guide, rubber roller, steel barbed shaft pressure paper wheel, etc. Because the belt guide scheme is mostly used in the field of direct injection, today we mainly talk about different printing equipment In order to reduce unnecessary waste of resources, how to choose between the steel barbed shaft pressure paper wheel transmission scheme and the rubber roller transmission scheme.

PART01

Pinch roller:

The paper pressing roller is generally located on the printing panel platform of the digital printing machine. It consists of a fixed frame and springs on both sides. Its function is to evenly fix the paper, and cooperate with the paper feeding shaft to transport the paper normally for the digital printing machine to make the paper run evenly. The paper pressing roller exerts pressure on the paper by lifting and pressing the small roller and the large paper feeding roller, adjusting the height of the pressing roller to adjust the pressing force, and finally achieves the effect of balancing the paper.

PART02

Glue roll:

The rubber roller machine does not have the strength support of the main engine, and is supported by two points fixed by the beam, and the paper is balanced by rewinding the paper on the rubber surface of the rubber roller.

When selecting the rubber roller, the rubber surface of the rubber roller should not have any impurities, blisters and air bubbles, let alone scars, defects, grooves, cracks and local sponges and different soft and hard phenomena. The performance of the rubber roller has a huge impact on the whole machine, and its requirements for process operation and production quality are also extremely strict. Among them, the selection of rubber and plastic materials and the control of product size and accuracy are the keys.

The accuracy of the roller head and bearing can directly affect the effect of paper feeding. In addition, if the poor lubrication causes the head of the rubber roller, the wear and clearance of the bearing will inevitably lead to uneven force when the paper is fed, and then the phenomenon of wrinkling will appear. At the same time, it will also cause paper indentation due to bad conditions such as jumping glue and slipping glue. Therefore, lubricating oil should be frequently added to the shaft head and bearing of the rubber roller to prevent the wear of the machine parts, affecting the normal use of the rubber roller, and thus affecting the balance of paper feeding.

Solution application types and advantages：

Rubber roller drive: higher paper pulling strength, tighter paper support, and more even and smooth paper feeding. It can play an excellent advantage on large-scale printing equipment with a printing speed of more than 500m/h.

Steel barbed shaft pressure paper wheel drive: For 15-head equipment and models below 15 heads, the paper-pressing wheel is fully capable of feeding, and its own equipment costs, post-maintenance costs, and consumption costs during use are relatively low .
