Handheld two-component sealant injector

Abstract

The invention discloses a handheld two-component sealant injector. The handheld two-component sealant injector mainly comprises a shell, a liquid inlet formed in the top of the shell, a sealant inlet formed in the middle of the shell and a sealant outlet formed in the bottom of the shell. A liquid inlet cavity is arranged below the liquid inlet. A spherical liquid inlet valve is arranged in the liquid inlet cavity and connected with a handle. The handle is connected with a stroke controller and also connected with a sliding rail, a sliding strip and a sliding sleeve provided with a pressing plate. Supporting springs are arranged under the handle. A sealant injection cavity is arranged below the liquid inlet cavity and connected with the sealant inlet. A disc-shaped sealant discharger is arranged under the sealant injection cavity. A mixing cavity is arranged under the disc-shaped sealant discharger and connected with the sealant outlet. The handheld two-component sealant injector is reasonable in structure, capable of being used conveniently and efficiently; instant mixing of two-component sealant can be achieved, and it is guaranteed that the mixing ratio is stable; the sealing effect is stable and reliable, and the handheld two-component sealant injector has broad application prospects.

Description

technical field [0001] The invention relates to the technical field of a glue injector for waterproof insulation of electronic appliances, in particular to a hand-held two-component glue injector. Background technique [0002] For the automotive electronic and electrical industry, in addition to the overall waterproof insulation, glue injection for key components and areas is the main way to improve the durability and reliability of electronic appliances. Coating insulation treatment and sealant treatment are the main methods of operation in this field. At present, the sealants used are mainly glass glue and silicone sealant. General industrial products are mainly silicone sealant. For more than 24 hours, the main disadvantages are the volatilization of harmful gases during the curing process, and the long curing process leads to the extension of the production cycle and the large area occupied by the site appliances. The two-component sealant solves the above problems very ...

Problems solved by technology

Coating insulation treatment and sealant treatment are the main methods of operation in this field. At present, the sealants used are mainly glass glue and silicone sealant. General industrial products are mainly silicone sealant. For more than 24 hours, the main shortcomings are the volatilization of harmful gases during the curing process, and the long curing process leads to the extension of the production cycle and the large area occupied by the site appliances. The two-component sealant solves the above problems very well, but it requires professional The equipment cannot be moved, and the electronic and electrical enterprises have various parts, the glue injection surface is very small, and the operating space is very limited. Many of them are not suitable for large-scale automatic production. In addition, after the two-component glue is prepared, if it is not used up in time , it will gradually solidify, which will not only cause unnecessary waste, but also affect the full play of the sealing performance
