A kind of soft fuel tank bag mouth forming process and structure

Abstract

The invention discloses a process and structure for forming a bag mouth of a soft fuel tank, belonging to the technical field of liquid containers. The inner circumference of A is a multi-layer annular groove that is fitted and sealed with the multi-layer annular boss of the flange body; The tensile strength of the flange body, the pure rubber layer A, the tape layer, and the pure rubber layer B can reach 4KN, and the airtightness qualification can reach more than 95%, which solves the problem of relying on the technical experience of the workers. The problems of uneven quality and unguaranteed connection strength increase the qualified rate. Because it is produced by using molds, the production efficiency is improved. The overall qualified rate of the soft fuel tank products produced by the above production method is high, which improves labor production. Strength, product appearance has been qualitatively improved.

Description

technical field [0001] The invention relates to a bag mouth forming process and structure of a soft fuel tank, and belongs to the technical field of liquid containers. Background technique [0002] On some high-speed sports equipment, in order to reduce the wind resistance during exercise, a soft fuel tank bag is often used as a container for oil storage, because during exercise, the amount of fuel will be slowly consumed, and the volume of the soft fuel tank bag It will gradually decrease with the consumption of oil, so as to achieve the purpose of reducing wind resistance; the mouth of the soft fuel tank is composed of a blue plate and a soft bag body. The production efficiency is low, the airtight pass rate of the connection between the blue plate and the soft bag body is low, and the quality of the connection between the blue plate and the soft bag body often depends on the technical experience level of the workers, resulting in uneven product quality. It is difficult t...

Problems solved by technology

[0002] On some high-speed sports equipment, in order to reduce its own wind resistance during exercise, soft fuel tank bags are often used as oil storage containers, because the amount of oil will be consumed slowly during exercise, and the volume of the soft fuel tank bag It will gradually decrease with the consumption of oil, so as to achieve the purpose of reducing wind resistance; the mouth of the soft fuel tank is composed of a blue plate and a soft bag body. At present, an adhesive layer is used to bond the blue plate and the soft bag body manually. The production efficiency is low, the airtight qualification rate of the connection between the blue plate and the soft bag body is low, and the quality of the connection between the blue plate and the soft bag body often depends on the technical experience level of the workers, resulting in uneven quality of the produced products, which is very difficult. It is difficult to ensure the connection strength of the joint, since the soft fuel tank bag is used on high-speed moving equipment, once the connection strength is not guaranteed, the consequences of oil leakage will be fatal
