Technical Field

The application relates to the field of machinery, in particular to a paging device and a front folding machine.

Background

In recent years, scientific books have been continuously improved and innovated from book size to cover form in order to meet the economic demand of the market. Many scientific and technical books design their covers into the form of a zip, and its characteristics are: the front of the original cover is added with a page, which is connected with the original cover into a whole and then folded back to the spine in the direction of the book binding opening. The newly added page is used as the cover of the book cover, and two more pages are arranged on the front and back of the original cover for publishing color advertisements, so that the economic benefit of the scientific book is increased. However, the book with the pull seal has a large width, and the folding direction of the front cover is different from that of the traditional book, so that the paging head of the front folding machine cannot separate the pull seal. Therefore, the problem that the conventional two-time adhesive binding process is high in material consumption, energy consumption and labor consumption is solved, and compared with the one-time adhesive binding process, the production cost is increased by times, so that the processing cost of the scientific and technological book is high.

Aiming at the technical problems of the prior art that the book is neither economical nor environment-friendly when the book is processed by the traditional process, an effective solution is not provided at present.

Optionally, the upper portion of the vertical rod is provided with a screw rod, and a second adjusting screw is arranged on the screw rod.

According to another aspect of the present application, there is also provided a front end folding machine, including: the paging device is used for paging the covers of the books and the book blocks of the books; the folding mechanism is connected with the paging device and is used for folding the paged front cover; and the cutting mechanism is connected with the paging device and is used for cutting the book block and the back cover of the paged book, and the paging device is any one paging device.

The paging device of this application can further enlarge the interval between front cover and the book block through the effect of paging gib block and guide rail through the front cover and the book block separation of paging blade with books to make front cover and book block and back cover get into respective subsequent handling respectively. Therefore, in the binding process of the pull-seal book, the device can be used for replacing a paging machine head of a traditional front folding machine, and the binding work of the pull-seal book can be finished by one-time glue binding on the premise of not damaging the cover of the pull-seal book. The technical effects of saving economic cost and working hours, reducing material consumption and realizing energy conservation and environmental protection are achieved.

Furthermore, the utility model discloses following beneficial effect can also be brought:

after the paging machine head is sealed by a front folding machine, a new one-time gluing and binding process is adopted, and the environmental benefits are mainly embodied in four aspects: (1) the new process saves electric energy by about 50 percent, reduces the cost expenditure of electric charge for enterprises, is indirect for environment and reduces the energy consumption during power generation. (2) When the hot melt adhesive pot is melted, the hot melt adhesive can volatilize a small amount of harmful gas, the working time of the pot is reduced by about 50 percent, namely the generation of 50 percent of harmful gas is indirectly reduced. (3) The old process adopts a twice gluing and binding method, and when the back is milled for the second time, the cut EVA hot melt adhesive chips belong to solid hazardous wastes and need special treatment. (4) The substitute front cover on the adhesive binding fashion for the first time is a transitional measure, and after the front opening burrs are cut, the front opening burrs need to be torn off, so that the adhesive binding fashion not only occupies the labor, but also generates a certain amount of waste paper. From the above four aspects, the environmental benefit of the new process is obvious.

Economic benefits are as follows: after the paging machine head is sealed by a front folding machine, a new one-step gluing and binding process is adopted, so that the economic benefit is very remarkable: (1) the new process reduces the consumption of the hot melt adhesive by about 50 percent. The main consumable material of the book processing is EVA hot melt adhesive, and the consumption of the hot melt adhesive used in each book is related to three indexes: the length of the book back, the thickness of the book, and the thickness of the glue. Generally, the more pages of the book, the thicker the book, and the thicker the back glue, so as to ensure the firmness of the book back. The back glue of the book can be considered as a cube, whose volume is: book back length, book thickness, adhesive thickness, hot melt adhesive consumption per book. We take the most common large 16K book, i.e. 210mm by 285mm book, for example, a book with a thickness of 10 mm. According to practical experience of many years, 2 bags of hot melt adhesive are consumed in every ten thousand of books and periodicals, and 4 bags of hot melt adhesive are consumed if the zipper book is subjected to a two-time gluing and binding process. If a new process of glue binding is used, in practice 2 bags of hot melt glue are saved per ten thousand books. The prices of hot melt adhesive varieties are slightly different, and the average price is about 25 kilograms per bag and 500 yuan per bag. The hot melt adhesive cost of each ten thousand books is saved by 500 x 2 to 1000 yuan, the books and periodicals needing to be processed by the whole company are counted to be 18 thousand books, and the hot melt adhesive cost is saved by 1000 x 18 to 1.8 ten thousand yuan in total all the year. (2) The new process reduces the power consumption cost by about 50 percent. The hot melt adhesive pot consumes 18 degrees per hour, the old process for processing 1 ten thousand books of zipper books consumes 48 hours, the new process needs 24 hours by one-time gluing, half of the power consumption time is actually saved, namely 50% of electric energy cost expenditure is saved, the power consumption per degree is 0.85 yuan, 1 ten thousand man hours is 24 hours, the power consumption per hour is 18 degrees, and the power saving cost per ten thousand books is as follows: 0.85 × 18 × 24 ═ 367.2 yuan, the annual electricity cost savings are: 367, 18 and 6606 yuan, the economic benefit is very remarkable only from the aspects of saving hot melt adhesive and electricity charge
