Piercing device and method for beverage capsules

Abstract

The invention discloses a piercing device for beverage capsules. The piercing device for beverage capsules comprises a bottom mold and a punch, wherein the bottom mold comprises a capsule positioninggroove and a piercing positioning structure; the capsule positioning groove is an annular inner groove; a side wall of the capsule positioning groove consists of a vertical main positioning plane anda secondary positioning plane of which the top is inclined outwards to form an oblique plane; the main positioning plane is projected out of the secondary positioning plane so that the capsule positioning groove is step-shaped; the piercing positioning structure is arranged in the center of the bottom surface of the capsule positioning groove, and is a hollow cylinder which is projected out of thebottom surface of the capsule positioning groove; the punch comprises a cylindrical head and a tail; the outer diameter of the cylindrical head is smaller than the inner diameter of the piercing positioning structure; the tail is fixedly connected with a piercing power mechanism; and the vertical projection of the punch drops in the piercing positioning structure. The invention further provides apiercing method. A pierced region of a capsule shell pierced on the basis of the piercing device and method is flat and smooth, and thus, the piercing device and method for beverage capsules are suitable for efficient industrial production of an assembly line.

Description

technical field [0001] The invention relates to the technical field of beverage production equipment, in particular to a beverage capsule punching processing device and a punching processing method. Background technique [0002] Capsule-based rapid beverage preparation systems are rapidly developing in the field of beverage preparation technologies such as coffee and tea, which complete beverage preparation by inserting capsules containing granular beverage preparation ingredients (such as ground coffee) into beverage preparation devices followed by rapid extraction. The device typically injects water into the capsule, where the beverage-making ingredients are dissolved or mixed into the water to form the beverage, and a deflector needle pierces the bottom of the capsule to deflect the beverage into a container. In some capsules, a piercing device is installed inside the capsule to avoid food problems such as mildew or pollution caused by the repeated use of the external gui...

AI Technical Summary

Problems solved by technology

In some capsules, a piercing device is installed inside the capsule to avoid food problems such as mildew or pollution caused by the repeated use of the external guide needle, which is difficult to clean. The beverage flows out of the capsule through a suitable outlet. Because the material of the capsule shell is usually made of high-quality The barrier multi-layer material is composited and then blow-molded. It has a soft texture and strong toughness. Therefore, in order to ensure that the puncture guide inside the capsule cannot pierce the capsule shell, it is usually punched at the bottom of the capsule shell first, and then used The solution is to heat seal the hole with aluminum foil. However, the current punching device is easy to form serrations, wrinkles or even serious deformation during the punching process, which seriously affects the production efficiency and yield of the industrial mass production of the punching process, resulting in production The cost has risen sharply
