(II) Modification procedures for single-sided micro-corrugated cardboard machine
1. Site mapping and checking of the relevant dimensions and technical parameters of single-sided machines and corrugating rollers, rubberized rollers, and metering rollers.
2. Site design pipeline orientation and high pressure turbine location.
3. Identify other modifications and repairs that must be added.
4. Select professional company production (general production time does not exceed the production cycle of the new corrugating roller).
5. The professional engineering and technical personnel of professional companies carry out on-site reconstruction projects and installation and commissioning (general conditions for 2 days, some new repair items can be removed and sent to professional companies for repairs at the same time), and operation training is also conducted.
According to our company's experience of retrofitting more than one hundred single-machines over the years, under normal circumstances, the entire rebuilding process requires only a few hours of downtime during on-site surveying and two days of downtime during installation and commissioning, with little impact on the user's production. If the supply and demand parties have a thorough and coordinated arrangement, the downtime can also be shortened. When the conditions permit, the ideal is to send the whole machine to a professional company to carry out overhaul at the same time. This will result in a brand new fine corrugated single-faced machine.
(III) Contents of other transformation and repair projects that must be added
Because most of the single-faced machines that need to be rebuilt are old machines, many parts have worn out and need to be repaired, replenished and updated, and other necessary renovation and repair projects may be added. (Checked by the engineering and technical personnel of a professional company)
1. Pressure roller repair after wear.
2. A new system is required for the wear of a pair of transmission gears on the lower corrugating roller and the pressure roller. (This item is not transmitted by the transmission and the universal coupling.)
3. Repair, replacement and replenishment of components for bearings, oil seals, sprockets, cylinders, and other transmission, pneumatic, sealing, and mechanical parts.
4. Restructuring, replenishment, replacement and repair of electrical control parts.
5. Overhaul costs. (Overhaul projects include repair of all rollers, cleaning and restoration of all mechanisms, repainting, etc.)
(IV) Reform costs
If it includes an overhaul, the 1600-sheet single-faced machine will cost about 100,000 yuan for the modification of the fine corrugated mullion.
(five) transformation cycle
The project is formally determined and generally used for 45 days.
In recent years, many customers such as Shanghai, Jiangsu, Zhejiang, Shandong, Hubei, and Guangdong have successfully transformed the company and achieved very good results and benefits.
In China, the application market for micro-tiles is gradually emerging. The small-scale corrugated single-faced machine transformation, low cost, mature and reliable technology, the transformation cycle is short, the impact of stop production is small, the user can enter the market development and application of new micro-corrugated cardboard products with the smallest investment, the fastest time, is a A good way. However, the fine corrugated single-faced machine reconstruction project involves a mature understanding of the principle characteristics of micro-corrugated mullion and a very professional design and process technology. At the same time, the production of micro-corrugated cardboard is a systematic project, from the choice of paper, the paper tension during operation. There are specific requirements for control, temperature and humidity control, and board quality control, etc. Professional companies' mature technology and debugging experience and operation training are key elements. Therefore, carton manufacturers should select professional manufacturers to undertake transformation projects, consult the professional manufacturers on the relevant transformation matters, and provide technical information on the technical level and technological strength of professional manufacturers and the use of their products, the after-sales service network and service quality of professional manufacturers, etc. Conduct thorough and detailed investigation and identification of the technical level of the product. Carefully choose as well.
