  • Intelligent Extraction Beverage Cooler
    Publication number: 20200305635
    Abstract: An intelligent extraction beverage cooler comprises a casing and a heating cylinder installed in the casing, a hot liquid container, a cold liquid container, a pot lid, a pot lid lifting mechanism, and a cooling system with multiple connecting pipes. The pot lid lifting mechanism drives the pot lid to lower into the hot liquid container along with an ingredient bag. The heating cylinder heats up the liquid and transports it to the hot liquid container. The ingredient bag is extracted to produce a hot beverage which is made into an iced liquid beverage by the cooling system without affecting taste thereof. This avoids bitterness or rancid taste of the hot liquid beverage. Additionally, the pot lid lifting mechanism drives the pot lid to open for convenience of putting in the ingredient bag.

    Abstract: A folding machine for folding fiber products and fiber products formed and stacked thereby are disclosed. The folding machine includes two folding devices, each of which includes a cutting device, a delivery wheel, a folding-line wheel, a platen wheel, and a folding wheel. The cutting device cuts the fiber product and transports the cut fiber product to the delivery wheel. The folding-line wheel is adjacent to the delivery wheel for making a first folding line on the fiber product carried by the delivery wheel, and then the platen wheel folds the fiber product along the first folding line. Subsequently, the once-folded fiber product is transported to the folding wheel. The folding wheels of the two folding devices are adjacent to each other and are used to fold the fiber product passing therethrough for a second time, and thus fiber products with three folds are formed.
