Problems solved by technology
[0003] During the printing process, the printing medium wrinkle will cause the printing image to be distorted, and different printing medium materials will produce uneven phenomena such as accumulation or scarcity, resulting in changes in physical and chemical characteristics, so that the electrical, thermal and light-conducting properties cannot meet the actual requirements; in addition, The wrinkling of the printing medium will also cause the deformation of the three-dimensional microstructure and the decrease of resolution. Therefore, in order to prevent the occurrence of such defects, a lateral micro-tensioning device and a tangential micro-tensioning device must be used to ensure that the two coordinate directions Slightly stretch the soft material, so that the soft material has a certain amount of micro-feed in both directions, and always ensure that the soft material is in a straight state

The invention discloses a straight and slight tension device for a continuous feed soft material. The device comprises a lateral slight tension device and a tangential slight tension device, wherein the lateral slight tension device comprises even number of roller pairs which are mutually meshed; each roller pair is composed of a cylinder type piezoelectric roller arranged at a first rotating shaft and a round table type rubber roller arranged at a second rotating shaft; the even number of the round table type rubber rollers are divided into two groups, and the small heads of each group of the round table type rubber rollers are towards the outside of the second rotating shaft; and the tangential slight tension device is composed of a driven gear, a driving gear and a spring, and the driven gear is a clockwise synchromesh gear fit with the driving gear. The device can keep the soft material straight all the time in the process of continuous feed, and provides a way for further improving the print quality of the soft material; and compared with the prior manufacturing method, the invention has the advantages of high efficiency, convenience, conciseness, small volume of investment and the like.
Description
technical field [0001] The invention belongs to the technical field of rapid manufacturing of soft three-dimensional microstructure units, and relates to a straight micro-tensioning device for continuously feeding soft materials, especially for soft OLED units. Background technique [0002] In various printing and inkjet markets, there is a phenomenon of wrinkling of the printing medium during the printing and inkjet process. Therefore, this straight micro-tensioning device for continuously feeding soft materials has great practical application value. [0003] During the printing process, the printing medium wrinkle will cause the printing image to be distorted, and different printing medium materials will produce uneven phenomena such as accumulation or scarcity, resulting in changes in physical and chemical characteristics, so that the electrical, thermal and light-conducting properties cannot meet the actual requirements; in addition, The wrinkling of the printing medium ...
