Description

Technical Field

[0001] This utility model relates to the technical field of pulp mixing devices, and in particular to a pulp mixing device for paper production. Background Technology

[0002] Tibetan paper originated in the mid-7th century AD and is a unique cultural product of Tibet. After Princess Wencheng brought papermaking techniques to Tibet, Tibetan and Han artisans, lacking the raw materials such as bamboo, rice, and fishing nets used in papermaking in Central China, explored and developed the unique Tibetan paper technique over many years. The paper used for various scriptures in the Potala Palace, Jokhang Temple, Sakya Monastery, and other places is mostly Tibetan paper, and it remained widely used in Tibet until the 1950s.

[0003] Tibetan paper is made primarily from the branches of shrubs belonging to the Thymelaeaceae family. The process involves soaking, washing, removing the bark, boiling, pounding, pulping, casting, and finally, peeling the paper. Tibetan paper is increasingly valued for its advantages, including resistance to decay, insects, and rodents, and its long shelf life.

[0004] Pulp is deposited in a pulp tank through a pulp screen for a certain period of time, and then evenly deposited on the surface of the screen to form a preform. If the pulp is suspended unevenly in the pulp tank, the resulting material layer will be of inconsistent thickness, affecting the product's shaping quality. Existing methods use stirring blades to agitate the pulp, but this method is limited and cannot agitate the pulp at the bottom of the mixing tank. Furthermore, the pulp can only rotate with the blades, resulting in uneven agitation and reduced mixing efficiency. Therefore, a pulp agitation device for paper production is proposed. Utility Model Content

[0005] In view of this, the present invention provides a pulp mixing device for the preparation of paper for Tibetan paper production, so as to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.
