Aluminum foil welding preforming equipment and technology

Abstract

The invention discloses aluminum foil welding preforming equipment and technology. The equipment comprises a cup body, a bed die and a preforming pressure head; the cup body is in a shape of a capsuleshell; a circular punched hole is formed in the middle of the bottom of the cup body; an annular positioning structure is arranged on the outer side of the circular punched hole; the outer contour ofthe lower part of the cup body faces the interior to shrink to form a circle of annular concave surface; a containing cavity is formed in the middle of the bed die; an annular supporting step which protrudes upwards is arranged in the middle of the bottom surface of the containing cavity; a circle of annular boss is arranged on the position, corresponding to the annular concave surface, of the inner wall of the containing cavity; a vacuumizing negative-pressure pipeline penetrates through the middle of the preforming pressure head; and an arc surface which is sunk inwards is arranged in the middle of the bottom of the preforming pressure head. According to the aluminum foil welding preforming equipment and technology, an aluminum foil is not liable to fall off, the punched hole is positioned accurately, a capsule product produced by the equipment and the technology is used so that the aluminum foil can be conveniently punctured inside a capsule so as to discharge water, liquid residues can be prevented from being generated, and therefore the food safety can be improved.

Description

technical field [0001] The invention belongs to the field of processing and forming equipment, relates to the technical field of production of containers or capsules for brewing / extracting solid substance beverages, and in particular relates to an aluminum foil welding preforming equipment and process.

Problems solved by technology

This kind of coffee capsules and coffee capsule machines bring great convenience to people to brew coffee, but at the same time, there are also some disadvantages. Many beverage capsules on the market currently use the method of piercing the water out of the structure of the beverage machine. The diversion needle pierces the water outlet method of capsule drainage. In this method, the remaining liquid food residue after drainage is difficult to clean, and it will cause food safety pr
