Abstract
Description
Technical Field
[0001] The invention relates to the technical field of Pu'er tea cake production equipment, in particular to a mechanism for separating and extracting flying paper in a tea cake. Background Art
[0002] Compressed Pu'er tea is the primary form of Pu'er tea. Most Pu'er tea products sold on the market, whether raw or cooked, are sold in compressed tea form, such as cakes, lumps, and bricks, with cakes accounting for the largest proportion. The Pu'er tea cake pressing process is a crucial step at the end of the Pu'er tea refining and production process. A cake press typically presses the blended tea leaves into Pu'er tea cakes of varying specifications, which are then baked and packaged to create the standard Pu'er tea compressed tea product. Currently, the Pu'er tea cake presses used by tea companies are all semi-automatic, all-in-one pressing and shaping machines. During operation, the cake press requires manual assistance to complete multiple operations, including removing the tea from the barrel, pouring the tea, arranging the tea leaves, placing the inner tea leaves, and grasping the tea leaves to press the inner tea leaves.
[0003] The inner leaf of Pu'er tea is a small piece of special paper embedded in the inside of the Pu'er tea cake. The inner leaf records the basic identity information of the tea, like the "identity card" of the tea, allowing consumers and collectors to trace the production batch and year of the tea. This is especially important for teas such as Pu'er, which pay attention to the year and origin. Some teas even need to be marked with the tea cake number. The inner leaf is also a way for tea companies to showcase their brand culture. The exquisite design and unique logo can deepen consumers' impression of the brand and enhance the brand image. This information helps consumers identify the authenticity and source of the tea and prevent counterfeit and inferior products. Over time, especially for aged teas, the inner leaf has become an important basis for studying the history of tea and the changes in tea culture, and is of great value to tea collectors and researchers.
[0004] Inner flying paper usually uses cotton paper, which is made of plant fiber and has good air permeability, which helps Pu'er tea to "breathe" during long-term storage and promote natural fermentation without being sealed too tightly, causing internal moisture or odor; cotton paper can properly absorb moisture from the surrounding environment, adjust the microclimate around the tea leaves, and avoid damage to the tea leaves due to excessive dryness or moisture, which is beneficial to maintaining the quality of the tea; cotton paper is mostly made of natural materials, without chemical additives, and has no pollution to the tea leaves, which conforms to the modern people's pursuit of health and environmental protection. It is also more suitable for contact with food; cotton paper is non-acidic, and in order to prevent yellowing and long-term storage Corrosion, which can better maintain the long-term clarity of paper and printed handwriting; although the inner flying paper is not directly edible, considering food safety, some high-end or traditional Pu'er teas will use edible-grade ink and cotton paper materials that meet food safety standards to ensure that the quality of the tea is not affected; compared with ordinary paper, cotton paper is softer and not easy to break, even if it is under pressure during the tea pressing process, it is not easy to be damaged, ensuring the long-term preservation of the inner flying information; using cotton paper to make the inner flying echoes the traditional Chinese papermaking process, adds to the cultural heritage and artistic beauty of Pu'er tea, and is in line with Pu'er tea's positioning as a cultural symbol.
[0005] In the prior art, as described in Patent CN112777074A, the inner fly paper is sucked up through a nozzle and then placed into the tea cake before pressing. Although a static-eliminating mechanism is added to the nozzle, the inner fly paper is made of cotton paper, which is light in weight, thin, and breathable. This can cause multiple sheets of inner fly paper to stick together during suction. This sticking is not entirely due to static electricity; it can also be caused by the strong suction force penetrating the air permeability of the inner fly paper and penetrating to the next sheet.
[0006] To avoid this problem, existing technologies use contactless suction cups. To prevent uneven suction, a push rod lifts the entire stack of inner-flying paper upwards and transfers it to the top end of a storage box, where the top sheet is removed by a suction head. Alternatively, the stack is placed in a storage box with a hollow bottom, and a suction mechanism extracts the bottom sheet. However, this method can cause the weight of the stack to change as the stack gradually decreases. As the push rod pushes the stack against the top end, the forces between the sheets change, disrupting the balance between suction and the suction head during suction, potentially leading to the simultaneous extraction of multiple sheets. If multiple sheets of inner-flying paper are present in a pressed tea cake, the product is deemed substandard. Once the pressed product is disassembled and re-pressed, severe fragmentation will occur, resulting in reduced product quality. Therefore, a separation and extraction mechanism is needed to ensure that only one sheet of inner-flying paper is extracted at a time, allowing the inner-flying paper to be placed in the pressing mold barrel after extraction. Summary of the Invention
[0007] To address the aforementioned issues, the present invention provides a mechanism for separating and extracting the inner fluff sheets of tea cakes. This mechanism replaces the traditional upward paper extraction method by placing the entire stack of inner fluff sheets sideways in a storage box. A pushing mechanism then pushes the entire stack forward to the outlet, whereupon a suction mechanism extracts the outermost sheet from the outlet for use. By controlling the thrust of the pushing mechanism on the inner fluff sheet stack and the suction of the suction mechanism to achieve a balance, only one sheet of inner fluff sheet is extracted at a time. Specifically, the present invention achieves its objectives by:
