Description

Technical Field

[0002] A foam is a glass product, a container for storing reagents in chemical experiments. A traditional glass tube foam blowing machine includes a primary mold mechanism, which is generally composed of a rotating mechanism, a disc, and a heating and flame-spraying mechanism. The glass tube is blown into a desired shape by air pressure, and then naturally solidified into a glass product. However, it is transported away by a conveying and cooling mechanism. During this process, the foam needs to be clamped by a clamping mechanism and placed on the conveying and cooling mechanism. The existing clamping mechanism has only one clamping jaw, which requires reciprocating motion. There is a problem of low clamping efficiency, which affects production. During the clamping process, the conveying mechanism needs to be used to cooperate with the clamping jaw to lift and lower. Since the conveying mechanism is large in size and heavy in weight, the power required for lifting and lowering is large, which not only increases the equipment cost and causes waste of resources, but also has the problem of unstable support, which easily leads to the breakage of the foam. It cannot meet the needs of actual use, so there is an urgent need for improved technology on the market to solve the above problems. Utility Model Content
