Description

Technical Field

[0001] The invention relates to packaging equipment, in particular to a round cake packaging paper folding device. Background Art

[0002] The round brick tea requires the packaging paper to be wrapped in a folding shape, so that the whole brick tea is beautiful and generous. The existing round brick tea is mainly packed by manpower. This brick tea packaging method is complicated and labor-intensive. The speed seriously affects the market demand for brick tea and greatly reduces production efficiency. When packaging the round brick tea, the packaging paper lining the bottom of the round cake brick tea needs to be folded and fit around the round cake brick tea, and then the packaging paper is folded to the upper surface of the round cake brick tea to form a folding package. Patent No. 201720515179.3 discloses a round cake brick tea packaging device, including a rotatable lower mold and a fixed upper mold; both the lower mold and the upper mold have through holes adapted to the round cake brick tea, and cooperate with an ejection mechanism, a downward pressure mechanism and a hollow mold plate to package the round cake brick tea. This packaging method causes the edges of the wrapping paper to form wrinkles in sequence and fold on the round cake brick tea and gather in the middle of the upper end surface of the round cake brick tea, while a gap is formed at the gathering point of the wrapping paper, resulting in poor sealing, which affects the storage and quality of the product, resulting in poor sealing effect of the round cake brick tea packaging and affects the sales of the product.

[0023] The working principle of the present invention is as follows: the packaging paper lining the lower part of the round cake is folded on the opposite sides and folded on the round cake, and the other two sides of the packaging paper form a folding cylinder. The peripheral device folds the folding cylinder upward so that the lower part of the folding cylinder fits the circumference of the round cake, and then moves the substrate so that the first notch surrounds the folding cylinder which is vertical at this time. After the closing plate moves with the substrate, it is located on both sides of the folding cylinder. The rotating shaft rotates and drives the cam to rotate. The cam abuts against the closing plate to move the closing plate, and the closing plates located on both sides of the folding cylinder are closed toward the middle, so that the folding cylinder is closed. At the same time, the substrate continues to move and cover the round cake and gradually presses the closed and wrinkled folding cylinder onto the round cake. After completion, the substrate and the closing plate return to their positions; after the peripheral device rotates the round cake 180°, the peripheral device folds the folding cylinder on the other side upward so that the lower part of the folding cylinder fits the circumference of the round cake. Then, the present invention repeats the above process, and closes, wrinkles and presses the folding cylinder on this side onto the round cake, so as to seal and package the round cake.
