All-water-blown spraying mechanism for high heat-resistance sound absorbing sponge used for automobiles

Abstract

The invention discloses an all-water-blown spraying mechanism for a high heat-resistance sound absorbing sponge used for automobiles. The all-water-blown spraying mechanism comprises a base body, a shell, atomizing nozzles, a recovery cavity and a control panel; the recovery cavity is arranged in the base body; a liquid outlet is formed in the outer wall of one side of the base body; an overturning mechanism is arranged at the central position of the top end of the base body; the shell is arranged above the overturning mechanism; the bottom end of the interior of the shell is provided with a power cavity; a storage cavity is arranged in the shell above the power cavity; a liquid inlet is formed in the central position of the top end of the shell; a limiting cover is arranged at the centralposition of the bottom end of the shell; a flow chute is formed in the bottom end of the shell in the limiting cover; and the bottom end of the flow chute is provided with the atomizing nozzles at anequal distance. Pollution to the environment when the spraying mechanism is used is avoided, so that a spraying effect when the spraying mechanism is used is improved, and moreover, the phenomenon that spraying liquid precipitates and coagulates when the spraying mechanism is used is avoided.

Description

technical field [0001] The invention relates to the technical field of spraying mechanisms, in particular to an all-water foaming spraying mechanism for high heat-resistant polyurethane sound-absorbing sponges for vehicles. Background technique [0002] The sound-absorbing sponge is made of polyurethane. Compared with the traditional ordinary sponge, it has good sound-absorbing, heat-insulating, flame-retardant, high-temperature resistance and other superior properties. With the continuous development of society, it has been widely used in various In the industry, the sound-absorbing sponge needs to be sprayed during the full water foaming process, so a corresponding spraying mechanism is required. [0003] At present, there are many kinds of spraying mechanisms on the market, but their functions are relatively single, and there are still certain problems, which have gradually failed to meet people's needs. The specific problems are as follows: [0004] 1. The traditional s...

Problems solved by technology

[0007] The purpose of the present invention is to provide an all-water foaming spraying mechanism for high heat-resistant polyurethane sound-absorbing sponge for vehicles, so as to solve the above-mentioned background technology that the spraying mechanism cannot recover the spraying liquid to reduce environmental pollution, cannot turn over the sound-absorbing sponge for multi-directional spraying and cannot Vibrate the spraying liquid to avoid the problem of precipitation and condensation
