在罐头行业中,目前国际市场上异形罐头食品的销售量长期以来畅销不衰,特别是304、306方听午餐肉的罐头不论在国内市场,还是在国际市场上,始终供不应求。但是,国内在封口质量方面尚存在一定问题,离出口的要求还有一定差距,在1978年上海益民食品一厂出口方听午餐肉过程中发生过严重的质量事故,引起了我们全行业的重视。因此,如何提高异形罐的封口质量问题是罐头行业面临的一项重要任务。异形罐封口质量的影响因素较多,当然,除制盖、制身设备、封罐设备和封罐滚轮的质量等重要因素外,模具是其关健。目前在国际上比较普遍地采用计算机来辅助设计和计算的手段,应用于机械设计和制造领域,在设计中采用CAD系统在国内也日趋发展。为了提高方罐午餐肉封罐质量,上海益民食品一厂从国外引进了SH 120和SHV 120封
In the canning industry, the sales volume of special-shaped canned foods in the international market have been selling well for a long time. In particular, the canned food of 304,306-lunned luncheons is always in short supply in the domestic market or in the international market. However, there are still some problems in the domestic quality of the closure, there is a certain gap between the requirements of the export. In 1978, Shanghai Yimin Food Factory exporter to listen to lunch meat in the course of a serious quality accident occurred, has aroused our industry-wide Pay attention. Therefore, how to improve the sealing quality of shaped cans is an important task the canning industry faces. There are many influencing factors on the quality of the special-shaped can sealing, of course, the mold is the key factor except the quality of the cap, body equipment, sealing equipment and sealing roller. Currently in the international community more commonly used computer to assist in the design and calculation tools used in mechanical design and manufacturing fields, the use of CAD systems in the design is also growing in the country. In order to improve the quality of cans lunch cans sealed pots, Shanghai Yimin Food Factory imported from abroad SH 120 and SHV 120
