Binding equipment configuration and maintenance (in)

3 sewing machine

The sewing machine can be divided into manual page-holding semi-automatic thread sewing machines and page-tying machines for automatic pagers. There are two types of locks: flat lock and cross lock. Judging from the quality requirements of customers today, it is a general trend to select machines that can use fine needles, fine lines, and fine gauges (to prevent the glue from penetrating into the book block from the needle eye and cutting off the signature after cutting). The cross lock line is much tighter than the parallel lock line, which reduces the thickness of the back of the book, prevents wrinkles on the back of the hardcover book, but does not adapt to the cross stitch between the two posts (easy to generate 1 ~ 2mm of the book Misplaced between posts). From the scope of application of the size of the sewing machine, we must be able to lock A3 (297mm × 420mm) to A7 (74mm × 350mm) size copy of the book. Therefore, selecting a sewing machine that can use 10 sets of fine needles, that is, semi-locked and cross-lockable, and the maximum size width is 297 mm, can meet the requirements of modern lock lines.

At the same time, the author strongly suggests that the core of the book after sewing should be compacted with a press to ensure the quality of the finished product. Because the book blocks formed after the lines have been locked by the lines are slack, especially when the book is made of thin and thick paper, the number of posts is large. The book blocks must be pressed so that the back of the book is flat, firm, stiff, and the thickness of the book blocks is basically the same. be consistent. At present, there are two kinds of mechanical and hydraulic compactors. Horizontal compact hydraulic compact machines are generally used. The pressure is about 10 tons, the speed is 20 pieces per minute, and the maximum thickness is 60 mm. Single and double pressure can be compacted. When operating this book, only the back part of the book block is pressed. The current book block compression has become an indispensable process in the book binding process.

4. Cutting machine

For single-sided cutters, it is best to use chrome-plated, nickel-treated table tops or synthetic material countertops to prevent rusting and the like from contaminating the last sheet. The types of three-sided cutter cutters are linear, diagonal, and arc. It is best to use an innovative arc-sweeping type cutter to avoid wrinkles on the back of books and to better solve broken problems. Although the rubber binding linkage and the hardcover linkage are equipped with a high-speed three-sided cutter, it is ideal to add a semi-automatic three-sided cutter for the fragmented objects, because for a thin book of about 3mm, the high-speed full-automatic three-sided cutout Machines are difficult to cope with, and multi-species, small-batch, sewing and spiral binding are only semi-automatic three-sided cutters that are flexible, convenient, and adaptable.

5. Le mouth machine

With the colorful and colorful decoration of the cover surface, the use of the chewing style has also been widely used. Therefore, defects and ills of the manual crouch are fully exposed. The machine not only saves process, but also has high output and low labor consumption. The most important thing is that the quality is stable and reliable (unmatched by hand), and it can deal with thick cardboard paper like 300g/m2 or more, and it can exceed the front of the book block. 3mm fake hardcover (in the past can not do it by hand). Therefore, the use of crouching machines to replace manual crocheting is a trend for future development.

6. Riding motive

From the perspective of open size, we must choose single-linked books that can be A3 (297mm x 420mm) in size, and double-up books that can be A3 (2lOmm x 297mm) in size, with a maximum thickness of 8mm. Pager 10 is more suitable for posts. Generally, there are two ways to measure the total thickness of a horse-riding co-motivation device: one is to measure the thickness of the back of the book, and the other is to measure the thickness of the spine region. Although the principle of lever amplification is applied, due to the relatively large pressure during the test, the former method can easily cause the fracture of the back of the book (breakage of the pressure wheel, etc.), while the latter is relatively good and the detection is stable. In addition, the saddle-stitching automatic control device must be complete (missing posts, multiple posts, wrong posts, etc.), and the detection and identification means must penetrate through the entire saddle stitching process.

7. Binder

According to different mechanical structures, the perfect binder can be divided into three types: linear, disc, and elliptical. The linear machine is a single-head machine, and it is slower. It is suitable for small quantities, multiple varieties, fast digital prints, and one-stop printing of all kinds of products.

Although there are still some shortcomings to be overcome, the disc machine has strong compatibility and easy adjustment. The three disc machines can replace a medium-speed flat-panel linkage line. The elliptical type is the mainstream model of the flat-loaded linkage line, which is fast and suitable for mass production. However, no matter what type of bookbinding machine, brush bottom rubber and side glue station should have broken glue device, which can prevent wire drawing, dirty cover and other phenomena. For the glue-lined line, the longer conveyor belt is necessary to ensure that the book is cooled before cutting, and book distortion can be avoided. It is best to have a 3 minute cure time. The common configuration of paperbacking assembly lines and linear machines is more scientific. The advantage is that they can subdivide products and perform their duties, avoiding “killing chickens with knives”, and they also have only linear capabilities for the large format and DaLekou products.
8. Hardcover

In recent years, hardcover products have also exhibited a variety of features and small quantities, and the demand has continued to decline. Due to the huge investment in hardcover equipment, production tasks are not fully guaranteed, so investment in hardcover joint ventures is not favored. From the current market point of view, to make full use of the site and the labor force, to make equipment investment can quickly recover, and better adapt to the production of many varieties and small batches, choose a compact, simple configuration block type hardcover models more in line with The current business needs.

9. Two mobile phones

In recent years, after-sale bookbinding companies have introduced second-hand equipment in many cases. Since used equipment is mostly used for a certain number of years, there will be varying degrees of wear and deterioration, coupled with the current lack of maintenance capabilities of the company itself, making most of the equipment operating conditions unsatisfactory, and some even Can not normal production. According to the analysis of the actual situation, the cost of equipment renovation plus the previous capital investment may be close to the price of the new machine. However, no matter how technically, qualitatively, or qualitatively, how used equipment is refurbished will not be able to reach new equipment. status. Moreover, mechanical parts and electronic components are either not lacking or they have already been eliminated, and it is necessary to maintain normal production. Therefore, companies must think twice about buying used equipment.
