Description

Technical Field

[0001] The utility model relates to the technical field of coating spraying, in particular to a spray gun for anti-corrosion coating spraying. Background Art

[0002] A spray gun is a device that uses the rapid release of liquid or compressed air as power. Spray guns are divided into two types: ordinary pressure type and pressurized type. There are also pressure spray guns, Carle spray guns, and automatic recovery spray guns. The spray gun in the industry can be directly filled with paint for use. When the paint spray gun is in use, air is generated by an air compressor, and the anti-corrosion paint is sprayed out through the nozzle at the front end of the static spray gun. A low-pressure area lower than the atmospheric pressure is generated in front of the nozzle connected thereto. The pressure difference generated at the spray gun nozzle sucks the paint out of the paint storage tank, and under the action of the high-speed jet force of the compressor air, it is atomized into fine particles and sprayed on the surface of the object to be painted. However, most paint spray guns use fixed nozzles on the surface, and the nozzles cannot be replaced. As a result, when the paint spray gun needs to spray different-sized parts, different spray heads need to be replaced to adjust the spraying distance of the anti-corrosion paint, making the use of the sprayer very troublesome. At the same time, it is impossible to spray paint on the inner side or hidden parts of the object to be painted.

[0003] Based on this, a spray gun for anti-corrosion coating spraying is now provided, which can eliminate the drawbacks of existing devices. Content of the Utility Model

[0004] The purpose of the utility model is to provide a spray gun for anti-corrosion coating spraying to solve the problems of troublesome nozzle replacement and inability to spray paint on the inner side or hidden parts of the object to be painted in the background art.

The liquid storage bottle 503 is threadedly connected inside the fixed sleeve 501 so that the liquid storage bottle 503 can be fixed in the fixed sleeve 501.

[0027] In one embodiment, as Figure 3 shown, the liquid extraction pipe 502 is made of a rubber hose, which can better extract the liquid inside the liquid storage bottle 503.

[0028] In one embodiment, as Figure 3As shown, the surface of the liquid storage bottle 503 is provided with friction depressions, which can increase the friction with the hand and facilitate screwing on and off the liquid storage bottle 503.

[0029] In one embodiment, as Figure 4 - Figure 5 shown, the replacement mechanism 6 includes a fixed head 601, a connecting sleeve 602, a connecting pipe 603, a connecting head 604, a fixing ring 605, a rear spray net 606, a rotating spray head 607 and a front spray net 608. One end of the liquid supply pipe 2 is fixedly connected to the fixed head 601. The surface of the fixed head 601 is threadedly connected to the connecting sleeve 602. One end of the connecting sleeve 602 is fixedly connected to the connecting pipe 603. One end of the connecting pipe 603 is fixedly connected to the connecting head 604. By screwing the connecting sleeve 602, the connecting pipe 603 is fixed on the fixed head 601 through the connecting sleeve 602. One end of the connecting head 604 is fixedly connected to the fixing ring 605. The inner part of one end of the fixing ring 605 is provided with the rear spray net 606.

[0033] Embodiment 2

[0034] In one embodiment, as Figure 2 shown, the connecting pipe 603 is in the form of a flexible hose, so as to spray the coating on the inner side or hidden part of the object to be coated, and enable 360-degree flexible spraying and non-dead-angle spraying.

[0035] Working principle: The above embodiment discloses a spray gun for spraying anti-corrosion coatings. When in use, rotate the liquid storage bottle 503. The rotation of the liquid storage bottle 503 causes it to move downward relative to the fixed seat 3 through the threads on its surface, so that the liquid storage bottle 503 can be removed. Add an appropriate amount of anti-corrosion coating into the liquid storage bottle 503, and then twist the liquid storage bottle 503 to fix it back to its original position. Twist the connecting sleeve 602 to fix the connecting pipe 603 to the fixed head 601 through the connecting sleeve 602, and install the nozzle on the spray gun body 1. Generate air through an air compressor, and then draw the anti-corrosion coating out of the liquid storage bottle 503 through the liquid extraction pipe 502 through the air inlet 8, so that the anti-corrosion coating enters the inside of the liquid supply pipe 2 and the connecting pipe 603. The anti-corrosion coating is then sprayed out through the rotating nozzle 607. When the anti-corrosion coating passes through the rear spray net 606 and the front spray net 608, it forms a water mist, thereby evenly spraying the anti-corrosion coating on the surface of the object to be coated. When it is necessary to change the spraying range, rotate the rotating nozzle 607 to change the distance between the front spray net 608 and the rear spray net 606, thereby changing the spraying range of the anti-corrosion coating and enabling better spraying. At the same time, when it is impossible to spray the inner side or hidden parts of the object to be coated, the connecting pipe 603 is made in the form of a flexible hose, so that the nozzle can spray paint flexibly in a 360-degree direction and spray without dead angles.
