BACKGROUND OF THE INVENTION

Field of Invention

This invention involves with a kind of coffee machine, especially involves with a kind of automatic coffee grinding capsule making machine.

Description of Related Art

As for the automatic coffee grinding capsule making machine adopting the existing technology, there are only coffee capsules of different brands/sizes and tastes for sale. For most out of these capsules, the brand manufacturers make several kinds of coffee capsules with the single taste respectively through massive production. In addition, there are very little amount of coffee capsules made by the users independently for personal taste. If the capsules made by the brand manufacturers are bought, the user does not have choice to select the coffee taste. In addition, one-time use is not environment-friendly. However, if the user makes coffee capsules independently for personal taste, there are many operating procedures, operation is complex, it takes a lot of time and it is easily dirty.

SUMMARY OF THE INVENTION

For the defect or deficiency of the existing technology, this invention desires to resolve the following technical problem, namely this invention will provide a kind of automatic coffee maker that can resolve the technical problem of the existing technology that the coffee maker only makes coffee with single taste and the operating procedure is complex.

For achieving the purpose above, this invention adopts the following technical proposal, namely a kind of automatic coffee grinding capsule making machine can be provided. The said maker consists of the base, automatic rotating operation platform, coffee cup unloading device, coffee bean grinder device, coffee powder temporary storage device, powder tamping and removal device, coffee cap unloading device and capping device; the said automatic rotating operation platform is provided at the said base; the said automatic rotating operation platform can rotate based on the coffee capsule making status; there are several first holes at the said automatic rotating operation platform, and there are several first detecting devices below the said automatic rotating operation platform; the said first holes are used for bearing the coffee cup; the said first detecting devices are used for detecting the working position of the coffee cup at the automatic rotating operation platform; the said coffee bean grinder device, the said coffee powder temporary storage device, the said powder pressing and removal device, the said coffee cup unloading device, the said coffee cap unloading device and the said capping device are fixed to the said base; the said coffee bean grinder device consists of the coffee bean storage bunker, the first motor, rotating shaft, grinder burr assembly, coffee powder collector and powder scraper; the said first motor is transversely fixed and connected to the said rotating shaft. The said coffee bean storage bunker, the said grinder burr assembly and the said powder scraper are fixed to the said rotating shaft in turn and toward the direction away from the first motor. The said powder scraper is fixed to the end of the said rotating shaft; the said powder scraper is inside the said coffee powder collector.

As the further improvement of this invention, the said grinder burr assembly consists of the grinder burr bracket, the first burr and the second burr. The said grinder burr bracket is vertically fixed to the said rotating shaft. The said first burr and the second burr can be dismantled from and fixed to the said grinder burr bracket respectively.

As the further improvement of this invention, the said coffee grinder device also consists of the grinder burr interval regulator. The said grinder burr interval regulator is used for regulating the distance between the grinder burr and regulating the fineness of the milled coffee powder.

As the further improvement of this invention, there is a first spring at the lower part of the said coffee bean storage bunker. The said first spring is nested to the said rotating shaft. One end of the said first spring is connected to the said coffee bean storage bunker, and the other end of the said first spring is connected to the said grinder burr assembly.

As the further improvement of this invention, the said coffee powder temporary storage device consists of a second motor, a second detecting device and a movable mechanical part; the said second motor is used for driving the movement of the said movable mechanical part; the said second detecting device is used for detecting whether the said movable mechanical part is in place or not; inside the said movable mechanical part, there is a volume-changeable cylinder cavity. The said cylinder cavity is used for placing the coffee powder conveyed from the said coffee powder collector. When the said cylinder cavity is filled with coffee powder, the said second motor will drive the said movable mechanical part to move. Wherein, as for the specific method for changing the said volume, the temporary storage devices or assemblies with different fixed volumes can be replaced.

As the further improvement of this invention, the said powder tamping and removal device consists of the third motor, the third detecting device, the second spring, powder tamper, flat scraper and a waste storage bin; the said third motor is connected to the said powder tamper, and the said second spring is nested to the said powder tamper; the said third motor is used for driving the said powder tamper to move upward or downward; the said third detecting device is used for detecting whether the powder tamper is in place or not; the said second spring is used for buffering the pressure exerted by the said third motor on the said powder tamper. The said flat scraper is used for removing the redundant coffee powder outside the coffee cup; the said waste storage bin is used for storing the discarded coffee powder.

As the further improvement of this invention, the said coffee cap unloading device consists of a fourth motor, the fourth detecting device, a push rod, coffee cap tray and a sliding track; the said fourth motor drives the said push rod and makes the coffee cap to move along the said sliding track and cap the coffee cup; the said fourth detecting device is used for detecting whether there is coffee cap on the coffee cap tray or not.

As the further improvement of this invention, the said capping device consists of a drum, roller, the third spring and a connection device; the said roller is provided at both ends of the said drum, and the said roller is connected to the said connection device via the said third spring.

As the further improvement of this invention, the said drum consists of the first drum and the second drum; the said first drum covers outside the said second drum; the said first drum is made of soft rubber; the said second drum is made of hard rubber; when the coffee cap caps the coffee cup, the said capping device will press the said coffee cap.

As the further improvement of this invention, the said coffee cup unloading device consists of a fifth motor, the fifth detecting device, a unloading mechanism and coffee cup tray; via the unloading mechanism the said fifth motor pushes the coffee cup on the coffee cup tray to fall into the said first hole; the fifth detecting device is used for detecting whether there is coffee cup on the coffee cup tray or not.

Beneficial effects of this invention: This invention discloses the non-industrial and automatic coffee grinding capsule making machine that integrates coffee bean grinding, powder tamping and injection for capsule and capsule capping and improves the licensed process of such maker. This invention has more compact structure, smaller volume and lower cost, and can be operated simply and conveniently.
