Description

Technical Field

[0001] This utility model relates to the field of polymer membrane surface treatment, and in particular to a plasma device for polymer membrane surface treatment. Background Technology

[0002] In modern industrial production, polymer membranes are widely used in numerous fields such as electronics, medical, and food packaging due to their excellent chemical stability, flexibility, and plasticity. However, the surface of polymer membranes is often inert, resulting in poor hydrophilicity and adhesion, making it difficult to meet specific application requirements. To improve the surface properties of polymer membranes, plasma treatment technology has emerged. Plasma can etch the surface of polymer membranes and introduce polar groups through physical and chemical actions, significantly improving the surface activity and adhesion of polymer membranes, thereby enhancing their compatibility with other materials and improving printing and coating effects.

[0003] Currently, most plasma equipment used for polymer film surface treatment on the market is equipped with plasma nozzles of fixed nozzle length.

[0004] However, in practical applications, for wider polymer films, if the nozzle length is fixed and small, it is necessary to move the nozzle multiple times or extend the processing time to cover the entire film surface, resulting in low processing efficiency. For example, in large-scale production, when processing wide polymer films, a nozzle with a fixed nozzle length will lengthen the production cycle and affect the overall production efficiency. Therefore, based on the above-mentioned problems, a plasma device for polymer film surface treatment has been developed. Utility Model Content

[0029] Working principle: A plasma device 3 is installed on the top of the processing table 1. In use, by placing the polymer film on the top of the processing table 1, the opening and closing of each electric nozzle 413 is first adjusted according to the width of the polymer film. By pulling the connecting rod 415, the sealing plug 414 moves along the inner wall of the storage tube 412, thereby adjusting the number of times the sealing plug 414 closes the electric nozzle 413 according to the width of different polymer films. The wider the polymer film, the more electric nozzles 413 are opened, thus quickly adapting to polymer films of different widths.

[0030] Subsequently, by rotating the knob 512 on the outer wall of the rotating bracket 511, the knob 512 drives the elliptical block 514 at the top to press the wedge block B616. When the wedge block B616 is pressed, it presses the connecting plate 613. When the connecting plate 613 is pressed down, it sequentially drives the spring C614 at the bottom, connected to the pressure plate 615, to press the polymer film. At the same time, when the elliptical block 514 presses the wedge block B616, it also presses the wedge block A5112. When the wedge block A5112 is pressed, it drives the fixing block 519 at the inner extension end of the crossbar 518 to press and fix the adjusted connecting rod 415, thereby ensuring the fixation of the sealing plug 414 at the inner extension end of the connecting rod 415. After the knob 512 presses and fixes the wedge blocks A5112 and B, the bolt 513 abuts against the outer wall of the knob 512 to fix and limit the knob 512 to prevent it from loosening.
