一、概况我厂生产的渔用塑料浮子是以吹塑法工艺生产,故在每只产品上都留有一个吹气的针孔,在试压前必须逐只封口。过去均采用电铬铁手工操作,生产效率低,劳动强度大,每人每班只能封焊3000只左右,并且每只产品封口处都留有焦疤,影响外观质量。为了改变手工操作落后面貌,进一步提高产品的质量,提高企业的经济效益。在81年设计了一台全气动控制塑料浮子针孔封焊机,于 I. Overview I plant the fishing plastic float is blow molding process, so each product has left a blowing pinhole, before the pressure test must only be sealed. In the past, electric ferrochrome was used for manual operation. The production efficiency was low and the labor intensity was very high. Only about 3000 sealing welds per class per person were available, and scorches were left on the sealing area of ​​each product, which affected the appearance quality. In order to change the backwardness of manual operation, further improve the quality of products and improve the economic benefits of enterprises. In 81 years designed an all-pneumatic control plastic float pinhole seal welder
