The configuration and maintenance of binding equipment (Part 2)

due to some new changes in the product structure of the printing industry, some new features and requirements have emerged, which also affect post press binding. For example, the printing varieties are increasing, but the quantity is decreasing. Therefore, when choosing the binding machine configuration, the focus is not limited to further improving the speed, but to decide to use different equipment to adapt to the actual situation of the enterprise (geographical location, site size, personnel structure, product positioning, etc.), so that the binding equipment configuration has greater adaptability, so as to achieve the maximum benefits

II. Equipment placement

before the installation of the binding machine, all preparations should be done carefully, including getting familiar with the technical data, selecting the placement position, preparing the foundation, formulating the installation plan, etc

when configuring the equipment, we should plan the placement of the equipment, put an end to the randomness of the installation position of the equipment, and oppose the wrong practice of placing the equipment wherever it is free. It is the key of production logistics management to scientifically follow how to minimize the flow distance of raw materials, semi-finished products and finished products and make the main logistics distance and location in the production process the most reasonable. Taking binding as the center should be fully considered and demonstrated in the whole process design of the printing plant. The shorter the logistics distance in the process of paper feeding, paper storage, paper preparation, printing and binding, the better. For example, adding an independent post press processing equipment near the fast digital printing equipment is to meet the requirements of short edition fast binding. The equipment placement must follow the principle that the binding machine, finished product warehouse and finished product delivery desk must be connected into a line, so as to ensure that the bound finished products can be directly warehoused and shipped. The reasonable layout and placement of equipment should comply with the above principles and focus on this process. The placement of machinery and equipment should also have a solid foundation as a guarantee. For the performance and use of 14 kinds of engineering plastics, and the eight functionalized engineering plastics modification, the machines placed upstairs should be scientifically calculated and demonstrated (for example, if the three side knife vibrates greatly during cutting, it should be placed on the main beam area with high bearing capacity). If the bearing capacity does not meet the standard, reinforcement and other measures should be taken to prevent foundation deformation and subsidence. In addition, the machine should be placed in a place with good ventilation (convenient for heat dissipation and drying), sufficient lighting (convenient for observing the state of the machine and checking Books), less land occupation and convenient for the operator (saving place, smooth access, improving efficiency), which has great social and economic benefits, and is conducive to turnover and stacking (convenient for the lower section). The place should be stable (preventing settlement and vibration from affecting the accuracy of the machine), so as to save time, labor, economy Reasonable

III. equipment maintenance

whether the binding machine can maintain normal production performance depends on whether the stable working period of the machine can be extended. Because the machine is used in different environments, the temperature, humidity, dust degree of the working environment and the level of user skills will cause the wear of machine parts in operation to a certain extent, and the wear of various parts is the most direct cause of machine failure. High quality management should keep the equipment in the best condition during the production process. If the bookbinding equipment is not maintained properly, it will not only cause many downtime failures, but also affect the accuracy of the product, but also affect the production capacity of the equipment. In fact, the problem of equipment maintenance is also a problem of corporate culture. If the operator only determines whether the equipment has faults by judging the quality of the finished products during the operation of the equipment, the environmental protection benefit of the equipment is 10 points significant. Under this background, employees will develop the bad habit of not doing relevant maintenance and not paying attention to maintenance. If our corporate culture pays great attention to quality issues, this situation will be avoided

equipment maintenance includes machine cleaning, machine lubrication and daily maintenance. Most enterprises can clean the machine and know it all day. The lubrication of the machine is not a difficult problem, especially the application of automatic lubrication system, which provides a reliable guarantee for the lubrication of the machine. However, many operators are not very clear about the daily maintenance of the machine. From the perspective of machine maintenance, routine maintenance has the greatest impact on product quality. After running for a period of time, the chain, sprocket, cam, etc. of mechanical parts will be worn to a certain extent, which will affect the accuracy of transmission. These parts should be regularly inspected, maintained, adjusted and compensated to maintain their transmission accuracy. It is very important to replace worn parts and update consumable components, which will directly have a significant impact on product quality. Such as paperback pressure plate, milling back knife, slotting knife, brake pad of three sided knife, cutting knife, chute, sliding ball, etc. are easily worn parts

and such consumables as suction head, conveyor belt, book stopper, cutting blade, etc. According to the use time and records, the operators should regularly replace vulnerable parts, easy to use aluminum with good conductivity and lead alloy with good electrochemical performance consumables, so as to avoid bad operation caused by mechanical wear, ensure the stability of machine performance, and provide guarantee for normal and lasting production

although it is very important to scrub and refuel the machine, it is more important to check the tightness of screws and the wear of parts when wiping the machine, because vibration (loose screws), wear of parts and other reasons will cause deviation of regular positioning and mechanical movement, which will directly affect the quality of products. At the same time, the quality of products should also be checked continuously in the production process to prevent accidents. The person who causes the machine to bite and die due to poor maintenance shall be investigated. Regular maintenance will help maintain the normal operation of the equipment, reduce maintenance costs, and effectively extend the service life of the equipment

equipment maintenance is a comprehensive discipline, involving all aspects, among which it is very important for operators to have a certain basic mechanical knowledge. If the operator lacks certain basic mechanical knowledge, it is difficult to use and adjust the machine correctly. If we can study and discuss according to the mechanical principle and in combination with the professional characteristics of binding machinery, and understand and master the working principle, action rules and structural characteristics of typical mechanisms in binding machinery, it will be of positive help to the adjustment, maintenance and upkeep in operation. In addition, the binding output is generally calculated according to the actual number of revolutions of the equipment and the recovery rate of 70% - 85%. Remember, too fast is not a good thing. Customers only care about whether your products are clean and meet quality standards, but they don't care how fast your equipment runs at all. Too fast running speed (or close to the upper limit speed) and overload running speed do great damage to the service life and accuracy of the machine, which should be paid enough attention

long term practice and statistics show that the failure rate of post press binding machinery is not invariable from the date of delivery. At the initial stage of delivery, the failure rate is often relatively high, because the machine is in the running in stage (equipment service life) at the initial stage of use. With the extension of service time, the occurrence rate of mechanical failure will be significantly reduced, which indicates that the machine has entered the stage of stable use (high production period of equipment). Usually, this stage will last for a long time (1 ~ 12 years). With the long-term use of the machine (more than 15 years), the failure rate will continue to rise again (equipment decline period), which shows that the machine is nearing its end, so it is necessary to make up our minds to update the machine
