Description

Technical Field

[0001] The utility model relates to the technical field of spraying machine superchargers, in particular to an improved spraying machine supercharger structure. Background Art

[0002] During the spraying operation, the sprayer is prone to uneven spraying effect due to unstable paint pressure. For this reason, a sprayer booster needs to be added to the spray gun of the sprayer. The sprayer booster in the prior art usually arranges an elastic rubber membrane between two hemispherical shells, and nitrogen is filled between the rubber membrane and the upper hemispherical shell. The rubber membrane and the lower hemispherical shell are connected to the inside of the spray gun. Although this structure can achieve a certain pressure stabilization effect, it has certain defects. The limited deformation of the diaphragm leads to a small pressure bearing range, which limits the scope of application. Moreover, the two hemispherical shell structures are easily damaged due to manual disassembly, and even the operator is mistakenly installed. The sealing performance is not good enough, and the paint will leak from between the two hemispherical shell structures. For this reason, we propose an improved sprayer booster structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the improved spray machine supercharger structure has the following advantages:

[0014] 1. Connect the connector to the upper end of the spray gun of the external spray machine through threads. When the pressure of the paint inside the spray gun is too high, the paint squeezes the rubber airbag, and the rubber airbag is squeezed and deformed to absorb the pressure of the paint. When the pressure of the paint inside the spray gun is too low, the rubber airbag expands under the pressure of the internal nitrogen, thereby squeezing the paint at the lower end of the rubber airbag, increasing the pressure of the paint inside the spray gun, and achieving a pressurization effect, thereby ensuring the pressure balance during the paint spraying process.

[0015] 2. A hexagonal ring is provided on the outer arc surface in the middle of the vertical part of the rotating T-ring. The T-ring moves upward relative to the second pressure ring to squeeze the spring, thereby adjusting the pressure on the valve core and the sealing effect of the valve core.

[0024] The working principle of an improved spraying machine supercharger structure provided by the utility model is as follows:

[0025] A hexagonal ring is provided on the outer arc surface in the middle of the vertical part of the rotating T-ring 54. The T-ring 54 moves upward relative to the second pressure ring 53 to squeeze the spring 55, thereby adjusting the pressure on the valve core 56 and the sealing effect of the valve core 56. Then, the valve seat 51 is connected to the internal thread of the airbag mounting ring 3, and nitrogen is injected into the air inlet provided at the upper end of the valve seat 51 through the air inlet nozzle 52. At this time, the pressure on the upper surface of the valve core 56 is greater than the pressure inside the rubber airbag 4. The nitrogen squeezes the valve core 56 downward, and the spring 55 is squeezed and deformed. The nitrogen enters the rubber airbag 4 to expand the rubber airbag 4 and fit it to the inner wall of the spherical shell 1. After the inflation stops, the valve core 56 is pressed against the lower surface of the air inlet of the valve seat 51 under the pressure of the spring 55. The end is sealed in contact to prevent nitrogen leakage, and the connector 2 is threadedly connected to the upper end of the spray gun of the external spray machine. When the pressure of the paint inside the spray gun is too high, the paint squeezes the rubber airbag 4, and the rubber airbag 4 is squeezed and deformed to absorb the pressure of the paint. When the pressure of the paint inside the spray gun is too low, the rubber airbag 4 expands under the pressure of the internal nitrogen, thereby squeezing the paint at the lower end of the rubber airbag 4, increasing the pressure of the paint inside the spray gun, and achieving a boosting effect, thereby ensuring the pressure balance during the paint spraying process. In order to facilitate the control of the activation and deactivation of the entire supercharger structure, a valve 6 can be threadedly connected to the lower end of the connector 2, open the valve 6 to put the rubber airbag 4 into use, close the valve 6 to deactivate the rubber airbag 4, thereby improving the scope of application.
