Description

Technical Field

[0001] The utility model belongs to the technical field of composite film processing equipment, in particular to a slitting machine with a directional slitting function. Background Art

[0002] Composite film is a material with excellent performance in the field of modern materials. By bonding base films or functional films with different properties together through gluing, a stable composite structure with rich performance is formed after curing. In the bonding step, there is a pressing process, which is used to improve the fit between multiple base films or between the base film and the functional film, thereby improving the fit of the composite material and thus improving the excellent performance after curing. In this pressing step, there may be a problem that the glue surface or glue liquid on the base film is not evenly distributed, resulting in the glue liquid overflowing from the composite edge of the composite film during the pressing process. With subsequent transportation and extrusion, the overflowing glue will increase the local thickness of the composite film, resulting in dimensional deviation, change the interlayer structure and glue distribution of the composite film, and affect the performance of the composite film itself. Severe overflowing glue may even adhere to the equipment, thereby affecting subsequent production.

[0003] Patent publication number CN114194911A discloses a device for forming easy-tear wide-width pharmaceutical composite bags. The device comprises a base frame and a feed assembly, with a feed assembly mounted on the upper side of the base frame. During use, the device automatically bonds two layers of film together to form a composite film, eliminates bubbles generated by the glue application, and folds the composite film in a taut state to prevent bulging at the fold. The device also fine-tunes the position of the composite film to prevent misalignment. It also automatically removes excess glue and cleans glue from the laminating roller to prevent it from contaminating the upper and lower surfaces of the composite film.

A pressing gap is formed between the two pressing rollers 303 and the arc surface of the support plate 304. The composite film passes through the pressing gap, and the composite film is pressed by the pressing roller 303. The edge of the composite film is cut by the slitting knife 305 to cut the overflowing glue edge, and the receiving roller 201 rewinds the cut composite film.

[0030] Furthermore, in some implementations of this embodiment, Figures 1 to 4 As shown, the device also includes: an expansion plate 306, multiple guide posts 307, and an adjustment post 308.

[0038] Furthermore, in some implementations of this embodiment, the heat sealing roller 203 is an electromagnetic heat sealing roller 203 .

[0039] In this embodiment, the heat sealing is more uniform, thereby improving the uniformity of the colloid between the composite films.

[0040] Furthermore, in some implementations of this embodiment, a plurality of anti-sliding blocks are provided on the receiving roller 201 , and the anti-sliding blocks are staggered.

[0041] In this embodiment, an anti-sliding block is provided to improve the reliability of the equipment during the winding process, thereby preventing tension failure or slipping from affecting the operational stability of the equipment.

[0042] To sum up, when using a slitting machine with a directional slitting function, the slitting position is adjusted by setting a slide rail 101 and an adjustment bracket 30, and the pressure roller 303 and the support plate 304 whose installation position can be changed, thereby further improving the positioning and pre-tightening of the composite film before slitting, so that the glue liquid is evenly distributed, preventing secondary glue overflow after slitting, and improving the slitting accuracy, thereby improving the efficiency in the production process of composite film materials and reducing scrap caused by glue overflow at the edge of the composite film.
