Problems solved by technology

However, as the rewinding process proceeds, the diameter of the protective film wound on the reel will gradually increase. After the diameter increases, the circumference of the reel will gradually increase every time the reel rotates, so that the reel It will gradually pull the protective film so that it is pulled and stretched, resulting in a decrease in quality, and it may be severely torn, resulting in defective products

Abstract

The invention discloses a protective film roll material punching die which comprises a bottom plate, a mounting frame is fixedly connected to the bottom plate, a second rotating rod is rotationally connected to the mounting frame, a rotating roller is fixedly connected to the end, away from the mounting frame, of the second rotating rod, and an adjusting mechanism used for adjusting the rotating speed of the rotating roller is fixedly connected to the second rotating rod. The adjusting mechanism comprises a fluted disc fixedly connected to the second rotating rod, an expansion frame is slidably connected to the limiting supporting frame in a limiting mode, a second gear is fixedly connected to the end, away from the mounting frame, of the first rotating rod, a second supporting frame is fixedly connected to the bottom plate, a rack is slidably connected to the second supporting frame in a limiting mode and meshed with the second gear, and a third rotating rod is rotationally connected to the mounting frame. The third rotating rod is fixedly connected with a first gear, and the fluted disc is meshed with the first gear. The adjusting mechanism further comprises a punching module which automatically achieves film cutting after film rolling is completed. During rewinding, the winding speed can be automatically adjusted, and meanwhile automatic punching and fixing of a protective film after winding can be achieved.

Description

Technical field [0001] The present invention relates to a protective film technical field of production technology, particularly as a protective film material of the punching die. Background technique [0002] The protective film can be divided according to use digital product protection film, automotive protective film, protective film home, food preservation protection film. With the popularity of mobile phones and other digital products in China, the protective film has slowly become a collectively screen protective film, and its screen is varied in the field of functional protective film, the first high-definition scratch, and to the present day Hong Kong REDBOBO OK8 functional protective film is favored. Material from the earliest PP material to the now increasingly popular AR material, intermediate experienced five years of development, slowly being accepted by the majority of mobile phone group. And for the growing maturity of the industry industrialization protective film...
