Description

Technical Field

[0001] The utility model relates to the technical field of die cutting, in particular to a positioning and laminating device for multi-layer material strips. Background Art

[0002] Die-cutting technology is a processing technology widely used in packaging, electronics, automobiles and other industries. Its main purpose is to cut raw materials into predetermined shapes to form the required parts. In the die-cutting process, accurate positioning is very critical, which directly affects the quality and production efficiency of the product; at the same time, the laminating device is also an indispensable part of die-cutting technology. Its function is to accurately fit the cut die-cut pieces together to form the final product.

[0003] In the existing laminating device, the die-cut parts are usually precisely positioned and laminated by a mold, or by a simple positioning roller. However, there are still some problems:

[0004] (1) The die-cut parts have high requirements for positioning accuracy. When the existing laminating device is used for continuous laminating, the die-cut parts are prone to deviation, and timely adjustment cannot be made. In addition, the overall laminating efficiency is low.

[0005] (2) When laminating die-cut parts with different internal patterns or shapes, the existing laminating device cannot guarantee the laminating accuracy due to the difference in the internal shapes of the two die-cut parts. Its functional defects will be further magnified, resulting in large deviations in the products after lamination, which ultimately affects the appearance and overall performance of the products.

[0035] In a preferred embodiment, the positioning hole 21 is disposed on the circumference of the internal pattern of the material strip 2 and is at a set distance from the internal pattern of the material strip 2 .

[0036] Specifically, in the present embodiment, three unwinding rollers 1 are provided, on which three material strips 2 with different internal patterns are respectively wound. A number of positioning holes 21 are evenly provided on the long sides corresponding to the internal patterns of each material strip 2, and the arrangement and spacing of the positioning holes 21 of each material strip 2 are kept consistent.

[0038] Specifically, by providing the positioning posts 31 and the positioning holes 21 that are arranged in a consistent manner, accurate positioning and one-time bonding between multiple groups of material strips 2 with different shapes and patterns are achieved.

[0039] In a preferred embodiment, the arrangement of the positioning posts 31 corresponds to the positioning holes 21 .
