introduction：●Shi Zenghui 1.introduction As everyone knows，Coffee beans are ground and then processed to make coffee，Some of the coffee grounds are produced in the process，In the past, coffee manufacturers mostly discharged these coffee grounds directly to sewage treatment stations，Not only greatly increase the cost of sewage treatment，It also wastes the coffee liquid with recycling value in the coffee grounds liquid。How to reduce costs，Reduce waste，It has become an urgent problem for coffee manufacturers to solve。therefore，It is necessary to design a system that can recover coffee liquid。 2.The production process of instant coffee and the generation of coffee grounds liquid （

introduction：In the mold groove inspection，The usual method is:①caliper、Depth gauge、Check slot dimensions with templates and other tools;②With salt、Wax or gypsum and other materials poured out samples，Check whether the slot is misaligned。These conventional methods can effectively control the die groove size of some relatively simple forgings，But for some complex forgings，Its mold groove size is difficult to detect completely，This will inevitably affect the production schedule，Increase production cost。This combined with the characteristics of the production of large-scale complex forgings in our factory and the actual situation in production，The inspection and control of mold are deeply explored and studied，Work out a solution

introduction：beam 1 introduction Reinforced concrete beam due to design or construction errors、The material does not meet the requirements、Use function changes or durability reasons，The crack width exceeds the allowable value of the specification or the bearing capacity is insufficient，Should be reinforced treatment。There are two kinds of reinforcement methods: non-prestressed reinforcement and prestressed reinforcement。The non-prestressed reinforcement method takes effect gradually when the concrete beam continues to deform，Therefore, the crack width and deflection of the reinforced beam will continue to increase，Its a passive reinforcement method。The main advantage of the prestressed reinforcement method is its quick effect，With the application of prestress，Camber arch，Crack width reduction，The stress of the original steel bar and concrete is reduced，Its an active addition

introduction：The application of the floating crushing roller in the pulp mechanism of the coating machine The gluing machine plays a connecting role in the whole corrugated cardboard production line，Whether the amount of glue is uniform，The position of glue wire is correct，Whether the corrugated shape is flattened、Amorphosis，All directly affect the efficiency of the production line and the quality of the cardboard。 The traditional gluing machine pulp mechanism is mainly the paper roller，In the past production line speed is low、Low production、Cardboard quality requirements are not high，It is simple in structure，Stable operation，Low manufacturing costs，It is widely used in China、Low speed corrugated board production line。however，In the production process，but
