As continuously developing overseas market, the fame of Shini systematic solution is raising. Recently, the construction of central conveying system in Poland has been successfully completed, and the central conveying system with 13 sets of injection molding machines and 6 sets of dehumidifying dryers have been planned. According to field investigation and customer demands, we customized this system solution with years of our engineer’s experience.
Conveying section: Because customer’s materials are contained in the big bag, we recommended our new feeding device of SES-800 auto loader of big bag that features simple structure and strong suction power, effectively avoiding material blocked in the feeding inlet of traditional white iron pipe during suction, and ensuring smooth material suction. In the feeding area, it planned three sets of SES-800, and mounted double-pipe shut-off valve that can convey the material in far distance and ensure no material residue in the pipe after suction. In each production line, there’re three material pipes for selection, and the pneumatic air backup valve is installed at the end of each pipe.
Pipeline section: The pipes are made of SUS304 stainless steel that is wear resistant and rustless, thus can protect material free of contamination; The tube selects PUR steel wire hose featuring anti-static, wear-resistant and aging resistant.
The SHR-12U-S+SICH-12U heat-insulated storage collective hoppers are collocated above the machines, and SHR-24U-S storage collective hoppers are employed above the Dehumidifying Dryers. A materials (virgin materials) are conveyed to hopper SHR-12U-S; B materials (regrinds) are output into the central vacuum hopper receiver SHR-24U-S above the shut-off valve; The regrinds are conveyed to the proportional valve from the suction box after two hours’ drying and dehumidifying to mix with material A as fixed proportion, and then enter into the hopper above the injection molding machine, which totally meets the demands of customer proportion. At the bottom of each Dehumidifying Dryer, it is available to work with two sets of injection molding machines.
Control section: The new Siemens PLC remote control, with low failure rate, strong extensibility and alarm monitoring function that meets the requirement of feeding up to 50-60 machines.
Integrated with the central conveying system, the workshop environment has obviously improved by reduced noise, increased production efficiency and greatly enlarged space utilization ratio, thus saving the production cost. This system also has won good reputation for developing the market in Poland and even the whole Europe in the future, and Shini is always committed to providing excellent system solution for every customer.
