615. What is the operating procedure of the hardcover linkage production line?
A: The hardcover linkage production line is generally composed of 13 units. Its operating procedures mainly include the following:
(1) Make all preparations before starting the machine, such as checking the individual machines. Lubrication and so on:
(2) Starting from the book block feeder, adjust the rules of each stand-alone machine according to the required specifications;
(3) Store the adhesive in advance and preheat it so that the viscosity is appropriate;
(4) According to the conditions of the rules, the various kinds of binding materials required are stored in advance and used;
(5) After completion of the preparation work, a signal will be sent, and the operation will be carried out on a single point and the connection will be made. If there is no error, then the signal will be sent. The linkage line can operate normally.
(6) In the normal operation process, each single machine should closely cooperate with each other. If any problem is found, it will be signaled to stop and be processed. Afterwards, the signal must be sent first to ensure the safe production of the linkage line.
(7) Wipe the equipment and clean the glue pan on time. Under normal operation of the equipment, one or two shifts shall be checked once every two weeks. The glue pan shall be cleaned once a month or with the wiper.
The maintenance of the equipment used for the binding of the post-press, the minor repairs shall be resolved during the erasure of the equipment, and the intermediate repair and overhaul shall be advanced by the senior engineer or the technical personnel responsible for the equipment, and shall fill in the maintenance report and report to the equipment department or the factory. The director of the equipment responsible for maintenance shall wait for approval before proceeding with maintenance, and shall be followed by the senior engineer or above. After passing the inspection, the two parties shall sign and approve it before they can test production.
Nine, the work process and operating requirements of various binding methods 616. What are the working procedures for the binding of books and books?
Answer: books. The binding of this booklet includes the two major processes of book block processing and book sealing processing.
617. What is the working process of book block processing?
A: The working process of book block processing refers to the process of printing from the printed pages, including page crash, blanking, folding, nesting, and matching. The processing of bookbinding, etc., is the process of creating a booklet with a booklet but not a cover.
618. What is the process of book closure processing?
A: The process of book closure processing refers to cutting the printed cover into the required specifications, pasting, hot stamping, and polishing. The process of wrapping outside the book block after processing such as laminating.
619. What are the binding methods for book binding?
A: The binding of books and publications mainly includes hardcover, paperback, and saddle stitching. Ancient line equipment. There are 6 kinds of methods such as butterfly and luxury equipment.
620. What is the working process of page crash?
Answer: There are two kinds of mechanical and manual collisions. The mechanical page collision is to loosen one sheet of pages with both hands, allowing the sheets to penetrate into the air, and then using mechanical vibration and pressure pad to collide with the original irregular sheets. Neatly; manual page collision is based on artificial shaking loose sheets, the original irregular neat page collision, there are two types of shock-type and impact.
621. What are the requirements for a missed page crash operation?
Answer: In the case of a miss-type page-flipping operation, pick up 1/3 or 1/4 of a ream of paper, pinch the sheets diagonally or on both sides of the sheet with both hands, bend it upwards and lift it up, so that the sheet goes in between The air, aiming at a corner, rubs back and forth with the palm of your hand and tiger's mouth, and the number of movements is neat and tidy. When a page breaks, one hand presses on one side of the paper basket and the other hand presses on the sheet to push the air out to complete the process of misoperation.
622. What are the requirements for a crash pager operation?
Answer: In the collision-type collision operation, both hands pick up a stack of sheets, pinch the two diagonals into the air, and then hold the two sides to stagger the stack of paper until the collision occurs. In the event of a collision, the hand must loosen the sheet and must not pinch the collision so as not to cause the curled edge to collide.
Whether it is a miss-move type or a bump-type page-fighting operation, the pages of the delivery should be relatively aligned (to be neat) when they are completed. Each page must be marked and distinguished, and must not be randomly placed.
623. What is the work process of opening materials?
Answer: The process of cutting materials is to select the blade, determine the method of opening the material, and open the material.
624. How to use the blade?
Answer: The cutters used for cutting materials are single-sided cutters, which have different specifications and are fully open. Off. Four kinds of types, such as four open, the length of the blade is the same as the specification of the paper cutter. When the materials are cut, one of them can be selected according to the size and requirements of the paper to be processed.
625. How to determine the blade angle?
Answer: The blade angle is determined according to the paper thickness, the paper quality and the height of the paper cut. That is, the most suitable blade angle is selected based on the cutting force of the cut paper bundle. blade. The smaller the angle is, the sharper the blade is, the smaller the cutting resistance of the object to the cutter, and the wear and power consumption of the cutter are also reduced. The larger the angle, the greater the shear resistance of the cut object to the cutter, and the wear and power consumption of the cutter also increases. However, the effect of cutting is very different. The former has a smooth but not durable incision, while the latter has a smooth but durable cut. Therefore, it is necessary to use a blade that can achieve smooth and durable cutting. Angle, generally 22-24 `is appropriate.
626. How to determine the opening method?
Answer: The correct cutting of paper is the key to opening materials, which is related to the accuracy of books and periodicals and the quality of processing in the next process. Therefore, 1 according to the construction plan requirements. Carefully analyze the layout and check the product name. Open number. Booklet, etc.; 2 determine which of the materials should be used to open the material; 3 calculate the number of copies; 4 can be opened before taking a sheet of paper, folded or painted on the mark, and then open the knife without error.
627. How to open materials?
Answer: According to the method of determination, a piece of printed sheet (usually 1 order) will be hit. The size or the drawn mark is adjusted to the back gauge. After the paper stack is placed on the top, the back gauge and the side gauge are to be adjusted. The cut paper baskets are checked for compliance and stacked neatly on the paper table.
628. What are the requirements for opening operations?
Answer: The requirements for the opening operation are as follows:
(1) When opening loose pages, the specification of the official post shall prevail, and the page number of the adjacent signature shall be accurately matched in place;
(2) When opening a chart, it should be proportional to the small margin of the text;
(3) When opening the cover material, the width of the spine and the edge trim should be accurately calculated according to the specifications of the book. Graphic text box and the book are uniform on all four sides;
(4) When opening hardcover book shell paper, all knife is used, no outer knife is needed to ensure that the cardboard does not have slopes and irregularities after cutting;
(5) When the hard-packing material is to be opened, a reasonable calculation shall be made according to the size of the specification. It is necessary to have a qualified size, save materials, and conduct scientific and rational material processing.
