Manufacturing method of wrapped foam roll and prepared wrapped foam roll

Abstract

The invention discloses a method for manufacturing wrapped foam rolls and the prepared wrapped foam rolls. The manufacturing method includes the following steps: S1, arranging a plurality of strips of wrapped foams in parallel at intervals on a typesetting film ; S2, transfer the typesetting film with wrapped foam to the carrier film; S3, when the typesetting film is close to the carrier film, remove the typesetting film, and transfer the wrapped foam on the typesetting film to the carrier film; S4, the The cutting knife above the carrier film punches the wrapped foam delivered above the carrier film in a skip-cutting manner, so that the wrapped foam forms a wrapped foam segment; S5, with wrapped foam Segments of carrier film are wound on spools to form wrapped foam rolls. The method for manufacturing wrapped foam rolls of the present invention does not generate waste, does not need to discharge waste, reduces related processes, and improves production efficiency. At the same time, material loss is reduced, and the utilization rate of materials almost reaches 100%.

Description

technical field [0001] The invention relates to wrapped foam, in particular to a method for manufacturing wrapped foam rolls and the prepared wrapped foam rolls. Background technique [0002] Electromagnetic waves can be emitted from the circuits of electronic devices through the atmosphere or transmitted through wires. Various electromagnetic waves generated by the circuits of electronic equipment will cause electromagnetic interference, which may degrade the performance of peripheral electronic equipment, cause noise in electronic equipment, damage electronic imaging, reduce the service life of electronic equipment, etc., and eventually cause electronic equipment to fail and cannot be used. . In addition, electromagnetic interference may also cause adverse effects on the human body and the natural environment. [0003] In electronics, communications, medical and other related fields, various filling materials with electromagnetic interference shielding are usually used t...

AI Technical Summary

Problems solved by technology

[0007] Due to the different number of typesetting strips of different wrapping foam rolls, the different warp and weft gaps between the segmental wrapping foams, and the different lengths of segmental wrapping foams, different types of wrapping foam rolls need to be made in different ways. Only molds can be produced, so a huge mold cost is required

[0008] 2. Efficiency issues

[0009] In the process of making strip wrapped foam into segment wrapped foam, the middle part needs to be removed, and the die cutting equipment sucks out and discharges the waste, so the production efficiency is very low

[0010] 3. Loss problem

[0011] In the process of making strip wrapped foam into segment wrapped foam, the utilization rate of strip wrapped foam is not high due to the need to remove the middle part, resulting in 40-60% material loss, resulting in waste
