In the glue, the use of the above process, feeding staff work is convenient, but in the milling back there is a serious not milling phenomenon, easy to cause page drop. The main reason is that the thick book inevitably shrinks the post phenomenon when bundling. Book back brush glue together, the consumption of milling cutter increases, and produce the phenomenon of book back turning edge. So the book can be changed to folding binding process. In addition to overcoming the above defects, the process saves personnel, and reduces the material loss. The disk package this machine uses four people, one person to check the number of posts, one person to feed the book, the rest on the cover, the book, etc., the work is relatively easy.
When making lekou book binding, use folding binding page for the first glue subscription book, r glue paper cutting door knife for the second glue binding process. In the use of disk package of the single machine binding can make the incision neat, but in the first time to increase the workload of four people. When the second glue on the cover, if the second milling back is not carried out, a layer of paper can be seen in the back glue, and the round endorsement is more, the appearance quality is not good. If the second milling back, the book backpack seal quality is good, but at this time the milling depth is increased, unfavorable to the machine, and make the size of the book less. Sometimes the binding output value is not worth the value of the milling cutter, the gain outweighs the loss.
Using folding baling waxing page brush glue cutting knife glue process, with baling glue instead of the first glue, cancelled the second binding process, increase waxing process, can save double working hours, baling brush glue requirements book back code qi edge (such as day), both sides interval to brush glue, make the book is not easy to spread, ensure the quality of cutting knife cutting. Make sure that the incision is neat when cutting it. If there is a small amount of unmilling back, the milling amount is added to 3.5mm. This method not only reduces the loss of milling cutter, but also ensures the quality of milling back.
This process flow can also be used on the ZXJD440A paperback binding line. Because the general book is thick, the number of posts exceeds the number of pages, can only be first pages after binding. If the use of two glue in the binding line, the second milling amount is too little, the back glue can not penetrate into the back of the book, the book is easy to stick not strong, easy to wrinkle or round endorsement, the quality of the package is not good. If the milling amount is too large, the book can not be opened and the size is wrong. Because the machine did not fall for the second time, even the edge of the glue can not brush. When the machine, we should pay attention to the channel spacing when the package of the book after the completion of the conveyor belt to prevent the deformation of the back.
