Description

Technical Field

[0001] The present invention relates to the technical field of Japanese paper thread production, and in particular to Japanese paper thread production equipment and a production method. Background Art

[0002] In the production process of existing Japanese paper thread, it is necessary to use a slitting knife to cut the Japanese paper, and the cut paper tape is then twisted into a thread. However, after the existing Japanese paper thread production equipment finishes slitting the Japanese paper, the distance between the slitting knife and the twisting device is relatively long, resulting in a long transmission distance of the paper tape. The paper tape is prone to drooping during transmission, which increases the friction during transmission of the paper tape, causing the paper tape to be easily torn during transmission. This will not only cause the loss of the paper tape, but also after the paper tape breaks, some devices need to be shut down, resulting in reduced production efficiency of the Japanese paper thread. Based on the above problems, we propose a Japanese paper thread production equipment and production method. Summary of the invention

When replacing a worn slitting blade (11), remove the mounting frame (7) from the production and processing table (1), rotate the locking screw (29) to separate the locking screw (29) from the mounting box (10), then remove the sealing plate insert (27) from the mounting box (10), and finally remove the slitting blade (11) from the corresponding mounting groove (28), insert the replaced slitting blade (11) into each mounting groove (28) in turn, insert the sealing plate insert (27) into the corresponding mounting box (10), rotate the locking screw (29), and use the locking screw (29) to fix the sealing plate insert (27) and the slitting blade (11); S7. After the mounting frame (7) is removed from the production and processing table (1), the limit plate (1204) is rotated to rotate the limit plate (1204) from a vertical state to a horizontal state, and the supporting platform (1202) is pulled, so that the supporting platform (1202) drives the dovetail slider (1203) to be pulled out from the dovetail groove, and the dovetail slider (1203) on the replaced supporting platform (1202) is aligned with the dovetail groove and inserted, and then the limit plate (1204) is rotated from a horizontal state to a vertical state, and the supporting platform (1202) is re-limited, and finally the mounting frame (7) is reinstalled on the production and processing table (1).
