Description

Technical Field

[0001] The invention relates to the technical field of book binding equipment, and in particular to a book wrapping device used in a high-speed binding machine. Background Art

[0002] Books are very common in our daily life, especially in the field of education, and are an important carrier for transmitting cultural knowledge. Against the backdrop of the trend of large-scale production of books, high-speed binding equipment has always been the mainstream of the post-press market, so there are high requirements for the performance indicators of each mechanism of high-speed binding machines; in this context, both the large-scale production demand of books and the improvement of product quality depend on the performance of each mechanism in the high-speed binding equipment, among which the stability of the binding mechanism is crucial to the quality of the book.

[0003] Compared with the old-fashioned binding equipment, the vibration and impact generated by the high-speed running machine will affect the life of the mechanism parts under the condition of high-speed mass production, resulting in the instability of the book forming effect. In addition, the old-fashioned binding mechanism also needs to manually adjust the clamping plate opening and the bottom plate height. When producing books of different specifications, manual adjustment is required, which is extremely inconvenient. At present, the working principle of the binding mechanism in the old-fashioned binding equipment is as follows: Figure 2 As shown, a book core 7 arranged in page number order is clamped by a book clamp 6, and the book clamp 6 is driven by a chain to perform periodic motion (the chain is not shown in the figure). After the book core 7 undergoes a series of processes (including rough milling, fine milling, grooving, applying bottom glue, side glue, and gluing the cover) through the periodic motion of the chain, it then comes to the process of book wrapping and forming. The book core 7 reaches the top of the book wrapping mechanism, and the two clamping plates 9 perform reciprocating linear motion to clamp the two sides of the book core 7, so that the cover 8 and the glue layers on the two sides of the book core 7 are firmly adhered, and the bottom plate 10 performs reciprocating linear motion to support the book back, so that the cover 8 and the glue layers on the book back are firmly adhered. In the whole book wrapping process, there are two critical actions, one is the clamping action of the clamping plate 9 on the book core 7, and the other is the sealing action of the bottom plate 10 on the book back. These two actions directly affect the forming effect of the cover and the book core. At present, these two actions of the old-fashioned binding equipment are inconvenient to operate and unstable. Summary of the invention
