China's cellular equipment technology needs to be improved and improved

After more than ten years of development, China's cellular equipment manufacturing industry has now entered the stage of improvement and improvement. It is understood that only a dozen companies that have built up and stopped the construction of cellular equipment manufacturers in China have been stuck. The manufacturing capabilities of the cellular equipment and the size of the company vary, and the types and performance of the equipment vary. For example, the dehydration process of honeycomb paperboard: electric heating, oil heating, microwave and steam dehydration; width of honeycomb paperboard: 1.6m, 1.4m, 1.2m, 1mt, etc.; honeycomb paperboard speed 40---100mm; honeycomb Cardboard processing speed 4m / min --- 8m / min --- 10m / min --- 20m / min, etc.; Honeycomb composite method with a paper coating compound, corrugated cardboard coating compound, surface coating, coating double function complex.
The horizontal coating method for honeycomb paper and the longitudinal coating method each have their own advantages: the horizontal coating can produce 1.6m wide paperboard with 1.2m paper, the paper consumption is reduced by 5-8%, and the strength is good, but the total output is low. Longitudinal sizing; high longitudinal sizing, longitudinal double-sided gluing process core speed 15m/---60m/min. According to statistics from the 2001 Beijing Cellular Development Symposium, there are more than 100 cellular production lines in the country, which have increased a lot over the past few years and have also come down. At present, there are inherent deficiencies in equipment manufacturing accuracy. According to the user's feedback, some devices are premature and leave the factory, causing installation and commissioning cycles of up to six months or more. Some devices are plagued with problems, causing users to transform and transform them to endless cycles. After the paperboard is compounded, it cannot be dehydrated and dried. Requirements, resulting in poor quality honeycomb paperboard, labor costs materials. These conditions have seriously hampered the development of the cellular industry.
To this end, the author proposes the following suggestions:
First, the process design <br> control the entire production line before the design must demonstrate to the final product. This is a process guarantee that determines the suitability of the product. According to the determined process line, the design arguments for each stand-alone unit and the main related parts are carried out to ensure that the entire line of the process is achieved before the task book can be written and the design can be carried out. Otherwise, the entire line will be congenitally deficient.
Second, the selection of procurement control <br> Design selection, standardization of parts and components, materials, components procurement collaboration and other related to the reliability of the equipment, must comply with ISO09000 related standards, electrical component control must use CCC products , CQC products, and IEC International Committee standard products, pneumatic, hydraulic components must also use good performance, reliable quality brand manufacturers. For cooperative units and supporting enterprises, we must choose the ISO09000 demonstration company. Strict selection of good selection, procurement, and collaboration in order to improve the reliability of the equipment.
Third, the manufacturing, installation quality control <br> Manufacturing: Manufacturing must be strictly in accordance with the process card procedures and drawings required for processing, according to standard procedures for control, process personnel must be familiar with the corresponding assembly relationship, the establishment of a three-tier quality control system, so that The manufactured parts meet the standards.
Installation: Installation is an important part of completing the design requirements and achieving the process goals. It is familiar with the assembly relationship and adjusts the accumulated tolerances that exist between the components to provide a reliable performance guarantee for the product process. An excellent team of installation and adjustment technicians must be established to accomplish the goals of the process requirements. It is recommended that the manufacturer's equipment be tested before it leaves the factory and sold after the standard is reached.
Fourth, after-sales service <br> After-sales service reflects the responsibility to the user in the end, but also represents the image of a company:
1. Establish a high-quality installation and debugging team to train operators and maintenance technicians for users.
2. Visit the users regularly to understand the use of the equipment and find out where the deficiencies are. Improve and improve in time.
3. Promise the warranty period for the user, eliminate the fault in time, and provide the necessary wearing parts so that the user equipment is in good condition for a long time.
4, to provide users with secondary processing equipment to help users develop secondary products, so that as soon as possible the formation of production capacity.
Fifth, optimize the process, reduce manufacturing costs, to provide users with first-class equipment <br> domestic cellular devices of different grades, different prices. Equipment performance, degree of automatic control, processing accuracy and equipment output are the main factors for price differences.
