Embodiment

[0018] A kind of anti-flange die-cutting process for aluminum foil of the present embodiment comprises the following steps:

[0019] S1 die-cutter pretreatment: Soak the die-cutter in 5% sodium hydroxide strong alkali solution, heat to 60°C, keep it warm for 30 minutes, take out the die-cutter and rinse it with clean water, then dry it in a dryer and install it for later use;

[0020] S2 Uncoiling: Put the aluminum foil parent roll on the unwinding device, the aluminum foil unwinds the material roll through the unwinding arm and the unwinding control roller, and keeps the unwinding tension constant;

[0021] S3 cover film: apply a double-sided adhesive layer on the front of the aluminum foil, and stick a release film on the other side of the adhesive layer;

[0022] S4 Slitting: The aluminum foil is guided by the traction roller to the bottom of the special die-cutter, and the upper and lower die-cutters cooperate with each other to cut the aluminum foil. When a cut is complet...

Abstract

The invention discloses an anti-flanging die cutting technology for an aluminum foil. The die cutting technology comprises: S1, immersing die cutting rules in 5% sodium hydroxide strong alkaline solutions; S2, placing an aluminum foil coil on an unwinding device, and uncoiling the aluminum foil coil through an unwinding arm and an uncoiling control roller; S3, pasting a double-sided adhesive tapeon the front side of the aluminum foil, and pasting a release film on the other side of the adhesive tape; S4, leading the aluminum foil to the position below the specially-made die cutting rules through a traction press roller, cutting the aluminum foil through cooperative application of upper and lower die cutting rules, purging and removing aluminum foil chippings adhering to the surfaces of the die cutting rules through a cleaning device while finishing primary cutting; and S5, placing finished products on a finished product packing tape which can be wound, and then winding the packing tape for packaging. According to the die cutting technology, through optimization of the die cutting technology and improvement of the die cutting rule structure, the aluminum foil chippings are prevented from sticking to the die cutting rules during die cutting, and meanwhile a stress bearing surface is provided for the aluminum foil during die cutting; and the occurrence of the flanging phenomenonduring die cutting of the aluminum foil is avoided.

Description

Technical field: [0001] The invention belongs to the technical field of aluminum foil die-cutting, and in particular relates to a flanging-proof die-cutting process for aluminum foil. Background technique: [0002] Die-cutting process is the most commonly used production process, which is to use a die-cutting knife to form a die-cutting plate according to the pattern required by the product design. craft. In the traditional aluminum foil die-cutting technology, because the aluminum foil is a relatively thin metal material, it often shows the phenomenon of edge flanging, and the appearance is difficult to meet the customer's requirements. Invention content: [0003] The invention aims to provide a flanging-proof die-cutting process for aluminum foil, which solves the edge flanging phenomenon during die-cutting of aluminum foil and improves the quality of aluminum foil die-cutting products. [0004] In order to solve the above technical problems, the technical solution of ...
