Technical Field
The invention belongs to the technical field of building decoration tools, and particularly relates to a foam caulking agent spray gun.
Background
The foam caulking agent has the functions of fixing, sound insulation, heat preservation, water resistance, leakage stoppage and the like, and is widely and widely applied in the building field. The filling of the foam caulking agent is achieved by a polyurethane foam spray gun, which is an indispensable tool for the high efficiency and accuracy of the spray gun in the use of the foam agent.
Referring to fig. 1, the foam spray gun consists of a gun body 1 and a foam tank access device 2.
Referring to fig. 2, the foam tank access device 2 comprises a foam tank interface 3, a foam channel 4 and a foam outlet end 5, wherein a ball 6 and a pressure spring 7 are arranged in the foam channel 4, when the foam tank interface is used, the pressure in the foam tank interface enables the ball 6 to compress the pressure spring 7, the ball 6 moves downwards, the foam channel 4 is opened, and foam is injected into a gun body from the foam outlet end 5 through the foam channel 4. When the foam tank is just started to be used, the foam pressure in the tank is larger, the foam sprayed from the foam outlet end is more, the pressure is larger, when the foam tank is used for a period of time, the foam pressure in the tank is smaller, the foam sprayed from the foam outlet end is smaller, and the pressure is also smaller. In order to adjust the ejection amount of foam, the opening of the nozzle of the foam spray gun is changed to adjust, so that the operation is inconvenient and the adjustment is inaccurate. Manual adjustment is needed, and labor efficiency is reduced.
Disclosure of Invention
The invention aims to solve the problems and provide a foam caulking agent spray gun which can automatically adjust the foam spraying amount at the foam outlet end.
The technical scheme adopted by the invention is as follows:
the utility model provides a foam caulking agent spray gun, includes the foam jar access arrangement on the rifle body, foam jar access arrangement includes foam jar interface, foam passageway and foam exit end, characterized by, the foam exit end is the pipe form, and the foam exit end tip is opened along the circumference has a plurality of logical grooves, sets up tubular base in the rifle body under the foam exit end, sets up the elastic sheet on the base, the elastic sheet is close to the foam exit end, the size of elastic sheet is greater than the external diameter of foam exit end.
Further, the through grooves are uniformly distributed at the end part of the foam outlet end.
Further, the depth of the through groove is 0.1 to 0.5mm, and the distance between the elastic sheet and the end of the foam outlet end is 0.5 to 2mm.
Further, the elastic sheet is circular and has a diameter 1 to 2mm larger than the outer diameter of the foam outlet end.
Further, the elastic sheet is made of one of nickel-titanium alloy, jin Ge alloy and indium-thallium alloy.
Further, the elastic sheet is made of one of acrylic and PE, PP, PVC, PC.
The beneficial effects of the invention are as follows:
when the elastic sheet is subjected to high foam pressure, the middle part of the elastic sheet is concave downwards, and the periphery of the elastic sheet is tilted, so that the outlet of the foam outlet end is smaller, and the foam spraying amount is reduced; when the foam pressure is reduced, the middle part of the elastic sheet is elastically restored, the elastic sheet tends to be horizontal, the outlet of the foam outlet end is enlarged, and the foam ejection amount is increased, so that the foam ejection amount is always in a relatively stable state.

Detailed Description
The following describes in detail the embodiments of the foam caulking agent gun of the present invention with reference to the accompanying drawings.
Referring to fig. 3, a gun body 1 of the foam caulking agent spray gun is provided with a foam tank access device 2, the foam tank access device 2 comprises a foam tank interface 3, a foam channel 4 and a foam outlet end 5, the foam outlet end 5 is in a circular pipe shape, a plurality of through grooves 8 of 0.1-0.5 mm are formed in the end portion of the foam outlet end 5 along the circumference, the through grooves 8 are uniformly distributed at the end portion of the foam outlet end 5, a tubular base 9 is arranged in the gun body 1 right below the foam outlet end 5, a circular elastic sheet 10 is arranged on the base 9, and the elastic sheet 10 is close to the foam outlet end 5, and the distance is 0.5-2 mm. The diameter of the circular elastic sheet 10 is 1 to 2mm larger than the outer diameter of the foam outlet end 5.
The elastic sheet 10 is made of an elastic material, and may be a metal material, such as nickel-titanium alloy, jin Ge alloy, indium-thallium alloy, or other titanium alloys. Or a polymer material such as acrylic or PE, PP, PVC, PC, and the thickness and distance from the foam outlet 5 are determined according to the elastic coefficient of the material.
When the foam tank is just started to be used, the pressure in the tank is high, the foam pressure sprayed from the foam outlet end 5 is also high, and when the foam tank acts on the elastic sheet 10, the middle part of the elastic sheet 10 is subjected to high pressure, so that the middle part is elastically deformed and recessed, the periphery of the elastic sheet 10 is lifted upwards, the gap of the foam outlet end 5 is reduced, the foam flow is reduced, and even the periphery of the elastic sheet 10 completely covers the end part of the foam outlet end 5, so that the foam can only be sprayed from the through groove 8.
As the pressure in the foam tank decreases, the deformation amount of the elastic sheet 10 decreases, and the periphery of the elastic sheet 10 recovers in the horizontal direction, so that the gap of the foam outlet end 5 becomes larger, and the ejection amount of the foam increases. Thus, when the pressure is high, the flow of the foam is high pressure and low flow, when the pressure is low, the flow of the foam is low, the total ejection of the foam is relatively stable, and the function of automatically adjusting the flow of the foam is realized.
The foregoing is merely a preferred embodiment of the present invention and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present invention, which are intended to be comprehended within the scope of the present invention.
