The purpose, working principle and characteristics of the optical film coater: The optical film coater is used for coating BOPP sealing tape. A layer of glue, pigment or ink with specific effect is coated on the rolled substrate, then dried, and then rolled up. It accepts a special high-speed coating head, which can be used to reduce the appearance of bubbles. The take-up and unwinding of the optical film coater are equipped with a full-speed automatic film receiving mechanism, and the tension closed-loop automatic control
日期：2023-02-28The air expansion shaft (air expansion shaft) driven by the slitter is divided into key-type air expansion shaft (air expansion shaft), plate-type air expansion shaft (air expansion shaft) and slip shaft.
日期：2023-02-20Type of stripper: 1. Parallel blade shear. The two blades of this shear are parallel. It is usually used for transverse cutting of blooms (square slabs) and other squares. Billets with rectangular section are also called billet shears. This kind of shear sometimes also uses two forming blades to cold shear rolled parts (such as round tube blank and small round steel, etc.). At this time, the shape of the blade is compatible with the section shape of the workpiece to be sheared.
日期：2023-02-20The optical film coating machine comprises a frame, a rear roller mechanism arranged on the frame, a feeding roller mechanism, a hopper mechanism and a scraper. The hopper mechanism of the product has inverted trapezoidal column layout, inverted triangular column layout and approximate semi-cylindrical layout, and the hopper mechanism is equipped with coating agent; The feeding roller mechanism of the product is soaked and fixed in the hopper mechanism; By changing the cylinder form of the feeding mechanism, the height of the feeding mechanism on the rack is increased, so that the height of the feeding roller is not easily lower than the liquid level of the coating agent, which ensures the coating agent and saves the coating agent. The layout of the optical film coating machine is simple and reasonable, the coating is high and uniform, and the finishing is convenient.
日期：2023-02-11As a kind of gravure coating, the micro-cavity coating machine belongs to roller coating. The difference between it and gravure coating mainly lies in the gravure roller diameter, back roller and the movement direction of gravure roller and substrate. With the increasing market demand for high functional films and the popularization of wet coating technology, the micro-cavity coating machine will be widely used in the high-end functional film deep processing industry.
日期：2023-02-11The polarizing film PVA mainly has the following distinctive characteristics: Light selection: select the light with the same polarization direction and widening direction;
日期：2022-12-19The important role of the polarizer plate is to convert the non polar sunlight into a deflecting star, so that the light perpendicular to the electrostatic field can normally show the image according to the LCD control panel. The basic function of the polarizing film is to change the sunlight of the polarizing film into a polarizer. Polarizing film is a new functional material of electronic optics, which can be used to make detection and polarizer. Polarization film is an important component that endangers the performance of LCD.
日期：2022-12-19In the process of improving and implementing the laminating and slitting machine equipment, the quality control was further strengthened and the sampling inspection was improved. The production and manufacturing of the whole machine shall not only be carried out according to the requirements of the processing technology, but also carry out strict quality inspection on the important process, especially the process, and strictly implement the process documents to ensure the quality of the goods. Adjust the coiling speed to the required range. Pay attention that the coiling speed is not too high when starting up, so as to avoid error correction and tracking. It can be adjusted to 20 and increased after startup. Start the machine.
