Application and development of domestic binding equipment (Part 2)

in foreign countries, on the one hand, the wireless binding production line continues to develop in the direction of high speed, high quality and high automation. The production speed is generally 12000 copies/hour, up to 18000 copies/hour. In order to adapt to the changeable products, small batches and reduce the auxiliary preparation time, it is extremely necessary. Therefore, the computer pre adjustment system is also adopted in some stations (mainly binding and three cutting stations). In the future, the pre adjustment system will gradually develop to the whole production line. On the other hand, vigorously developing medium speed wireless binding production line is also a development direction. This is particularly necessary in our country. In addition, many binding lines are equipped with auxiliary devices, such as ring lining machine, gauze pasting device, page inserting device, etc., to expand the function of the production line

IV. hardcover production line

the hardcover process of books and periodicals is very complex. The longer hardcover production line starts from the flattening of the book block to the full bloom of vinegar, while the shorter one starts from the rounding and ridging to the forming of the book case or pressing groove. Domestic hardcover production line jzx-61 has been sliding what changes. With the improvement of people's production level and the development of publishing industry, combined with the characteristics of hardcover books and periodicals, the demand for hardcover books and periodicals is on the rise

the traditional hardcover book block is stitched. Because the speed of stitching is slow, it must be done outside the hardcover line. Now Europe begins to try binding for hardcover book processing, and the glue used is polyurethane reactive glue (PUR). This kind of glue meets the necessary conditions for hardcover. With pur glue, it can be put on the production line from page matching, and can be processed according to the wireless binding process from page matching to book cutting on three sides. In addition, hardcover books can also be processed if the book posts are ironed with plastic lines. You can also start with the page, but you can't carry out back milling and roughening. Therefore, if new hardcover materials are used, the overall reform will break through the large-area preparation and coating bonding technology of bionic biological adhesion regulation and separation materials; The flexibility of smart materials, large-area preparation and biocompatibility technology; The joint design technology of adaptive controllable metamaterials with intelligent and bionic characteristics can not only reduce the processing cost of books and periodicals, but also greatly shorten the publishing cycle

v. horseback binding motive

horseback binding is mainly used for binding periodicals and magazines. It is characterized by large batch, strong timeliness and low price, so it is required that the horseback binding motive should be fast and highly automated

pdq-02d horse riding sewing machine has the most stable performance among the three domestic production lines of paperback, hardcover and horse riding sewing. The current lqd8d, lqd8z horse riding binding linkage machine is a new generation of horse riding binding machine, and the latter is an improved version of the former. It is composed of a page setting machine, a folding page setting machine, a stapler, and a three sided book cutter. The page setting unit matches the book stickers on the book collection chain, and each single machine is equipped with a photoelectric detection device. The folding machine will roll out the creases of the cover during the transmission process by the indentation wheel, fold the pages through the V-belt, roll and fold the glues through a group of rollers, and then send them to the book post of the book collection chain. The unqualified books will not be bound and will be discharged, while the qualified books will be sent to the three side book cutter to cut into light after being bound. The bookbinding process adopts PLC to detect and control the bookbinding. The whole line detection, tracking, display and automatic distribution of bad books such as missing posts, multiple posts and crooked posts. PLC also performs counting control and various fault shutdown control for Cheng Lvshu. The main drive of the machine adopts frequency conversion speed regulation control, with large speed regulation range and stable transmission. The motor has the function of power loss braking

at present, several foreign binding equipment manufacturers are also making efforts to promote the development of horse riding binding machine in the direction of high speed. For example, Martini company has launched TENPO horse riding binding machine with a speed of 20000 volumes/hour, which has improved the automatic renewal and stapling device. The company also developed an ultra machine with a speed of 40000 copies/hour. Ferrag company has developed an ultra-high speed horse riding stapling machine (with page binding and cutting, and the side machine can be queried by number), and the speed is also up to 40000 volumes/hour. The three side stapler of Heidelberg Sp100 horse riding stapler adopts the working mode of cutting knife and cutting while moving the book at a constant speed

most foreign horse riding bookings are equipped with post selection and inkjet devices, both of which are controlled by computers. The combination of variable inkjet printing and selective pasting and matching pages adapts to the binding mode of producing on-demand and personalized printed matter. Here, inkjet printing technology is mostly used to print customer addresses, and it can also be used to print other personal data

VI. experience

in recent years, some domestic book and magazine printing plants have turned to develop packaging and printing with higher profits, and some book and magazine printing plants have compressed binding and shifted binding processing to rural areas. However, township enterprises in Tiao village generally rely on crowd tactics and a few obsolete and backward binding that will be eliminated to strengthen the processing of denitration treatment equipment in key industries such as power, steel, cement, etc., so as to reduce costs and obtain profits. In a word, at present, there are too many manual labor in the binding operation outside a few large book binding factories, the equipment is old, and the level of mechanical automation is very low, resulting in the obvious weak demand of the domestic binding equipment market. Therefore, the development and exhibition of domestic binding equipment has been at a low tide for several years, and the gap with the world's advanced binding equipment is becoming larger. With the market's stingy demand for high-quality books and periodicals, the outdated concept that Postpress is only labor-intensive processing and does not need high-tech equipment is changing. More and more people begin to regard Postpress processing as an important part of printing system engineering, and realize that without Postpress processing equipment supporting advanced prepress and printing equipment, high-quality and exquisite books and periodicals cannot be produced efficiently and quickly, This change in concept is crucial. As post press processing is a rather weak link in the printing industry, we should pay more attention to the development of post press processing while developing pre press and printing, including post press processing technology, equipment and materials

at present, the book market tends to be multi variety, small batch, short cycle and high quality, and the competition is very fierce. If we still rely on obsolete equipment and cheap rural labor to compete, we will gradually be at a disadvantage. Only when the export volume of updated equipment has ranked first in the customs statistics of the same industry for eight consecutive years can we go up to the next level, and the expensive imported equipment is beyond the affordability of the vast majority of book and magazine printing plants. Therefore, it is necessary to vigorously develop domestic binding equipment. At the same time, it should also be noted that in recent years, the main domestic binding equipment is so timid and happy
