A capsule removal device and a brewing device

Abstract

The present invention discloses a capsule removing device and a brewing device, including a rotating shaft. The rotating shaft is provided with at least one guiding cylinder, and the guiding shaft is provided with a corresponding number of capsule cups. The guiding cylinder is sleeved on the capsule cup. A conical guiding wall is arranged inside the guiding cylinder, and a conical accommodating cavity is arranged inside the capsule cup. The conical guiding wall and the conical accommodating cavity form a conical brewing cavity for accommodating the capsule. A piercing needle penetrates into the capsule, and hot water is injected into the capsule through the piercing needle. After brewing is completed, the rotating shaft rotates around its own axis, and the capsules in the brewing cavity gradually pour downwards. At the same time, when the rotating shaft rotates, it drives the guiding shaft to move along an arc-shaped path in the arc-shaped guiding groove. The arc-shaped guiding groove guides the guiding shaft. When the capsules in the brewing cavity pour downwards, the guiding shaft drives the capsule cup to move away from the guiding cylinder, and the capsule cup also moves away from the capsules in the brewing cavity. The capsules gradually detach from the capsule cup. When the capsules completely move downwards, the capsules fall out of the capsule cup by gravity to complete the material discharging.

Description

Technical Field

[0001] The present invention relates to the technical field of automatic vending coffee machines, and particularly relates to a capsule removing device and a brewing device. Background Art

[0002] The current capsule coffee machines use a manual control method for adding capsules and brewing. Each time of manual flavor selection and manual brewing will cause a change in the original product flavor, and the handling of the capsule cup after brewing needs to be realized manually, and the function of automatic vending cannot be achieved. The utility model patent with the publication number of CN208404178U discloses a capsule coffee powder brewing automatic vending machine. However, during the automatic vending process, after brewing the capsule drink, it needs to be taken out from the capsule cup, that is, the capsule is removed. However, the existing capsule removing device uses an electromagnet to drive the insertion fork to insert the capsule through the electromagnet, and then the capsule is separated from the placement position. After the electromagnet is powered off, the insertion fork for inserting the capsule retracts and resets by the spring force to realize capsule removal. But after using for a period of time, the spring force is not enough, resulting in the difficulty for the insertion fork to retract and reset, and the capsule still stays on the insertion fork, resulting in a capsule removal failure. Therefore, how to provide a capsule removing device that can smoothly remove the capsule from the capsule cup is a technical problem that those skilled in the art need to solve urgently. Summary of the Invention
