In the printing industry , binding is currently the most important form of book binding, and the glue binding machine has become a common "equipment" for domestic book printing enterprises, in which the production speed is 4,000-7000 copies per hour. The package is the most popular. However, in the printing and production of books and periodicals, the design and manufacture of any equipment is impossible to perfection. The production efficiency and product quality of the actual book binding are also difficult to be affected by factors such as raw materials and process flow. Therefore, the equipment operator should optimize and improve the original equipment based on the production and operation requirements of the enterprise, so as to maximize the machine performance.
The book block that has been milled over the spine will be sent to the rubber backing, and the rubber scraper will be controlled by the rubberizing wheel, leaving the length of the book block to be glued, and then scraping off the excess glue. In this process, the operator's adjustment of the gel breaking parameters is very important, because if the gel is broken too early, the book block will not be fully glued, and there will be a short phenomenon after cutting; if the glue is too late, it will be on Too much glue to the book block, when the book block is sent to the support platform and the cover skin is squeezed and squeezed, the excess glue will be extruded onto the top surface of the platform to form a wire drawing, and the more accumulated, the back, dirty Back phenomenon, and falling on the conveyor belt will make the belt sticky, so the conveyor belt has to be cleaned frequently, causing unnecessary trouble to the operator and affecting the production progress. Therefore, some operators simply adjust the book clips to the side of the blade on the left side of the platform, and let the book rules out the platform, so that the platform and the book block are not pressed at the center of the force, so that the machine is hit. The difficulty of platform adjustment is increased.
A small trick to solve this problem: directly remove the part of the left side of the platform plate, so that when the book block and the cover are bonded and squeezed, it is just finished on the edge of the top plate, so that the glue will not be forced out, the work efficiency Higher, the finished book cover is also very beautiful. It is more appropriate to remove the specific pallets, and the operator needs some experience. The operator can try a little adjustment according to his own needs (recommended to remove 12.2mm).
After removing the pallet, you should also re-adjust the equipment zero position. The specific method is: jacking up the platform and turning the cam to the high point, that is, when the platform pallet is just about the top of the spine, the book clip chain and the main shaft are separated, so that the right side of the book holder and the left side of the pallet are removed. The blade faces are aligned or a few millimeters larger. Then, the platform is pulled up and the cam is pulled out and rotated by one pitch, and then reloaded.
