Description

Technical Field

[0001] This utility model specifically relates to the field of film slitting technology, and more specifically to a film slitting device. Background Technology

[0002] As one of the important end forms of polymer material processing, film is widely used in many fields such as packaging, electronics, optics, new energy, and medical. Its demand continues to grow with the expansion of downstream industries. In the film production and application chain, the slitting process is the core link connecting "mass-scale substrate manufacturing" and "customized end-user demand". Upstream film production lines usually produce wide-width, large-diameter master rolls, while downstream applications require narrow-width, fixed-length or specific-specification finished rolls. Film slitting equipment is the key equipment to realize this "wide-width master roll → customized finished roll" transformation. Its technical level directly determines the precision, quality stability and production efficiency of the finished film.

[0003] Traditional film slitting equipment typically uses film transport for slitting, requiring coordination between a feeding device, a transport device, a slitting device, and a winding device to achieve the desired slitting effect. However, during transport slitting, discrepancies in film dimensions can easily occur, preventing effective slitting according to the set dimensions. This negatively impacts the quality and efficiency of the film in later use.

[0004] A search revealed that Chinese patent application CN202421508057.8 discloses a film slitting machine for film production; it includes a base plate, and a lifting and slitting mechanism is fixedly installed on one side of the upper surface of the base plate. The lifting and slitting mechanism includes a support plate, a movable groove, a movable column, a bearing, a bearing plate, attachment components, a movable rotating rod, and cutting blades. The support plate is fixedly installed on one side of the upper surface of the base plate. A movable groove is opened inside the top of the support plate. A movable column is movably installed inside the movable groove. A bearing is movably installed at the bottom of the movable column. A bearing plate is fixedly installed at the bottom of the bearing. Several attachment components are fixedly installed on the side of the bearing plate away from the movable column. A movable rotating rod is movably installed inside the attachment components. Several cutting blades are fixedly installed around the outer circumference of the movable rotating rod.

[0005] The device in the aforementioned patent achieves the slitting effect by transferring the film to the bottom of multiple cutting blades and adjusting the contact between the cutting blades and the film. Since the cutting blades in the aforementioned patent achieve the rotation effect through the transfer of the film, this can easily cause squeezing between the cutting blades and the film, resulting in incomplete film slitting and adhesion between films, thus affecting the slitting efficiency and quality of the film.

In this device, the sleeve of the film is placed on a rotating roller, and the auxiliary plate and the swing plate are moved by an electric push cylinder, so that the rotating block on one side of the swing plate cooperates with the other end of the rotating roller, thereby effectively ensuring the stability of the rotating roller during rotation.
