Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a wood anti-corrosion spraying device. Background Technology

[0002] Anti-corrosion spraying equipment is a device that uses mechanical pressure to atomize anti-corrosion solvents and spray them evenly onto the surface and deeper layers of wood. It can efficiently achieve wood preservation treatment. Wood is susceptible to mold, insects, and moisture erosion, which can cause it to rot. Anti-corrosion spraying equipment can spray preservatives onto the wood to form a protective layer, blocking the growth environment of microorganisms and delaying the aging of wood. The combination of these two methods not only preserves the natural characteristics of wood but also significantly extends its service life. It is widely used in outdoor landscaping, building materials and other fields, and is a key piece of equipment for wood preservation treatment.

[0003] In existing technologies, some wood preservative spraying devices mainly consist of a preservative, a nozzle, and a spray gun. The preservative is delivered to the spray gun via pipeline. Inside the gun, the high-pressure preservative is mixed with compressed air and atomized at the nozzle, forming fine and uniform droplets. The operator holds the gun and aims it at the wood surface. The atomized preservative droplets adhere to the wood surface and penetrate into the wood grain and pores with the help of pressure. As the solvent evaporates, the preservative forms a solidified protective layer on the surface and inside the wood, blocking the path of erosion by mold, woodworms, etc., while enhancing the wood's moisture resistance, thereby achieving preservative protection for the wood and extending its service life.

[0004] In existing technologies, some wood preservative spraying devices extract the preservative from the storage tank and discharge it directly from the spray gun. This makes it difficult to precisely measure the amount of preservative to be sprayed during the spraying process, which easily leads to waste. Therefore, a wood preservative spraying device is proposed to solve the above problems. Utility Model Content

[0037] Working principle: First, the preservative is delivered to the delivery pipe 94 through the delivery hose 97. Under the action of the electric telescopic conveyor b91 driving the piston 98 to move backward, the preservative is sucked into the connecting pipe 93. At this time, the control component 95 at the bottom of the delivery pipe 94 is in the open state, the valve core 954 slides upward, pushing the valve cap 951 out of the valve body 952. The preservative can then flow out of the control component 95 at the bottom through the feed channel 956 and the discharge channel 955. Under the action of the electric telescopic conveyor b91 driving the piston 98, it enters the delivery pipe 94. When a certain amount is reached, the valve body 952 slides downward under the action of the spring 953, and the control component 95 at the bottom is in the closed state. At this time, the electric telescopic conveyor b91 pushes the piston 98 to move forward, and the control component 95 at the top changes from the closed loop state to the open state, sending a certain amount of preservative into the spray gun head 81.

[0038] When the preservative enters the spray gun head 81, pulling the trigger 3 causes the firing device 4 to slide in the spray gun body 1, triggering the device to draw in air through the air supply pipe 10. The air pressure valve 11 can adjust the air intake speed to achieve appropriate air pressure. The air is transmitted from inside the spray gun handle 2 to the nozzle interface 7, and the regulating valve 12 is adjusted to further regulate the device. Then, it is sprayed out from the nozzle interface 7, so that the preservative filtered by the filter barrel 82 is pushed by the air through the filter plate 84 and the baffle 85 on the left side and finally sprayed out through the nozzle 86. When the nozzle 86 is blocked, the electric telescopic machine a831 is activated to push the breaking needle 832 downward to vibrate and break up the debris accumulated in the nozzle 86. Under the push of the air, it is discharged.
