Description

Technical Field

[0001] This invention relates to the field of intelligent cooking equipment, specifically to a device for dispensing solid powders. Background Technology

[0002] A quantitative feeding device for solid powders (such as seasonings) in cooking is equipped with a powder outlet and a screw propulsion device. Driven by the screw propulsion device, the powder in the container is displaced towards the outlet and falls into the cooking container through the outlet. Summary of the Invention

[0003] The technical problem solved by this invention is to improve the accuracy and efficiency of quantitative dispensing of solid powders.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a double-helix quantitative dispensing device, comprising a powder container with a powder outlet, a pusher screw disposed in the powder container, and a motor for driving the pusher screw. The powder container and the motor are disposed on a base. The number of pusher screws is a pair, and the pair of pusher screws are arranged in parallel. Each pusher screw is equipped with a driven gear, and the pair of driven gears are driven by the same driving gear. The driving gear is connected to the motor.

[0005] Driven by a motor, a pair of pusher screws can quickly push solid powder towards the powder outlet to improve powder dispensing efficiency. Moreover, the twin-screw design ensures thorough mixing of the solid powder, improving the accuracy of powder dispensing.

[0006] The bottom of the powder container is provided with a screw cavity, and the pusher screw is set in the screw cavity. The front end of the pusher screw is pivotally connected to the front bearing seat, and the tail end of the pusher screw is pivotally connected to the tail bearing seat. The front bearing seat is fitted in the front bearing seat cavity, and the tail bearing seat is fitted in the tail bearing seat cavity, and is fixedly installed on the base.

[0007] The tail end of the pusher screw is equipped with an external spline, which mates with an internal spline shaft. A driven gear is mounted on the internal spline shaft. The internal spline shaft is pivotally connected to the tail end bearing housing via a bearing.

[0008] The base has a vertical plate section, and the vertical plate section has a gear chamber, in which the driven gear and the driving gear are arranged.

[0009] The base is provided with a discharge port slot, in which the powder discharge port is engaged. The bottom of the discharge port slot is hollowed out. Solid powder in the powder container falls through the powder discharge port and then falls into the food container through the hollowed-out structure at the bottom of the discharge port slot.

[0010] A stirring component, comprising a square frame and a gear disk, is placed inside the powder container. A shaft is mounted on the square frame, and the gear disk is fixedly connected to the square frame and shaft. The gears of the gear disk mesh with a pusher screw, and the two ends of the shaft abut against the inner wall of the powder container. The pusher screw drives the gear disk to rotate, which in turn drives the square frame and shaft to rotate, thus stirring the solid powder inside the powder container.

[0011] The twin-screw extruder and stirring element of this invention can improve the accuracy and efficiency of quantitative dispensing of solid powder. Attached Figure Description
