The utility model provides a suction head, an adsorption assembly with the suction head and FPC stripping equipment. The suction head is used for adsorbing an FPC, an air cavity is formed in the suction head, a first connecting hole communicated with the air cavity is formed in the first surface of the suction head, the first connecting hole is used for installing the suction head, a profiled groove is formed in the second surface of the suction head, the shape of the profiled groove corresponds to the shape of the FPC, a plurality of air holes are formed in the bottom face of the profiled groove, and the air holes are communicated with the air cavity. And each air hole is communicated with the air cavity. According to the scheme, the suction head can be pressed to the FPC, the FPC is attached to the groove, the air holes formed in the bottom face of the groove generate suction force at the same time, all parts of the FPC are adsorbed at the same time, in the process, the FPC is not prone to distortion and deformation, and therefore the FPC can be stably peeled off from the transparent bottom film.

The present invention relates to C08J, and more specifically, to a double casting device and a double casting preparation method for a film. It includes: a first windshield and a second windshield. By arranging a support roller at the support body just below the film falling position of the second die head, a supporting force facing the direction of the casting die head is applied to the support body, so that the strip support body and the roller have a certain fitting area. The fitting area is at the film falling position of the casting. Since the strip support body and the roller are completely fitted, the position stability of the strip support body at this position can be provided. At the same time, a windshield device is arranged before and after the second die head casting direction, and a suction device is arranged on the outside of the die head relative to the windshield device in the casting direction of the second casting nozzle. The inventor found that the lateral difference and unevenness of the film falling can be avoided, so that the local thickness of the film finally formed is uniform, the film is flat, and the peeling is stable. It can be used for -micron thickness casting film, as a TAC film for polarizer.

The present invention provides a fruit peeling device applied to the technical field of fruit peeling. By arranging an end peeling piece, the fruit to be peeled is driven to rotate relative to the end peeling knife, so that the end of the fruit is peeled. By arranging an adjustable peeling piece, the fruit is peeled by driving the adaptive peeling piece to move on the outer surface of the fruit. By arranging the adaptive peeling piece, when the peeling knife contacts the surface of the fruit, the peeling knife is pushed to rotate by arranging a spring 2, and the angle of the peeling knife is changed to adapt to the curvature of the fruit surface, so that the end of the fruit and the square part or the curved part of the middle turning point are peeled, and then the comprehensive peeling of the fruit is realized. A multi-station mounting frame is used to drive multiple fruits to rotate at the same time, so that the loading and end peeling, outer surface peeling and unloading of the fruit can be carried out simultaneously, so that the end peeling piece and the adaptive peeling piece are always working to peel, thereby improving the peeling efficiency.
