Description

Technical Field

[0001] This utility model relates to the technical field of electric kettle production equipment, specifically to an automatic coating machine for the bottom plate of an electric kettle. Background Technology

[0002] When installing an electric kettle, the aluminum plate needs to be coated with flux on the outside. The flux is used to promote the bonding between metals during welding or brazing. In addition, the flux forms a liquid film during brazing, covering the surface of the aluminum plate and the filler metal, isolating oxygen in the air and preventing the aluminum plate from oxidizing at high temperatures.

[0003] However, many manufacturers do not consider the second advantage of flux and usually only spray the aluminum plate on one side where it is welded to the metal. This spraying method is relatively simple. Usually, a conveyor belt is used to transport the aluminum plate and a spraying component is installed above the conveyor belt to spray the upper side of the aluminum plate. However, when this spraying structure sprays the aluminum plate on both sides, it is necessary to manually flip the aluminum plate and then transport it by the conveyor belt. This method affects the efficiency of aluminum plate spraying.

[0004] To address the aforementioned technical problems, this application proposes an automatic coating machine for the bottom plate of an electric kettle. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this invention aims to solve is that when using a conveyor belt to transport aluminum plates and a spraying assembly to spray the upper side of the aluminum plates, this spraying structure requires manual flipping of the aluminum plates before conveying them via the conveyor belt, which affects the efficiency of aluminum plate spraying.

[0007] II. Technical Solution

[0008] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: an automatic coating machine for the bottom plate of an electric kettle, including a coating box, wherein a first transmission component and a second transmission component are installed inside the coating box, a first conveyor belt is sleeved on the outside of the first transmission component, and a second conveyor belt is sleeved on the outside of the second transmission component. The first conveyor belt and the second conveyor belt move in opposite directions and are installed at an inverted angle. The second conveyor belt is located below the first conveyor belt and multiple sets of support bars are installed on its outside.

[0009] Spraying pipes are installed above the first conveyor belt and the second conveyor belt respectively. The spraying pipes are fixedly installed on the rear side wall of the coating box and multiple sets of spraying heads are installed on the lower side.

[0010] The coating box is provided with a feed inlet and a discharge outlet on the same side. The feed inlet is close to the feed end of the first conveyor belt, and the discharge outlet is close to the discharge end of the second conveyor belt.

[0011] As an improvement, the height of the discharge end of the first conveyor belt is lower than the height of the inlet end, and the height of the discharge end of the second conveyor belt is lower than the height of the inlet end.

[0012] As an improvement, two sets of baffles are installed on the rear side wall of the coating box. The baffles are located on the side of the spray pipe near the inlet and outlet, and the lower sides of the two sets of baffles are respectively close to the upper sides of the first conveyor belt and the second conveyor belt.

[0013] As an improvement, a receiving plate is installed through the inside of the feed inlet, and a material transfer device is installed through the inside of the discharge outlet.

[0014] As an improvement, an assembly trolley is installed on the outside of the coating box, near the material transfer device. The assembly trolley includes a base plate and a receiving platform.

[0016] III. Beneficial Effects

[0017] The advantages of this invention compared to the prior art are as follows: when the aluminum plate moves on the upper side of the first conveyor belt, flux is sprayed onto one side of the aluminum plate. After single-sided spraying, one side of the aluminum plate moves from the first conveyor belt to the upper side of the second conveyor belt. The aluminum plate is then pushed downward by the support bar, causing the aluminum plate to flip over on the upper side of the second conveyor belt. Flux is then sprayed onto the other side of the aluminum plate, thus achieving automatic spraying of both sides of the aluminum plate and improving the spraying efficiency of both sides of the aluminum plate.
