Description

TECHNICAL FIELD

[0001] The utility model belongs to aluminium profile processing instrument field, concretely relates to a kind of aluminium profile surface coating solidification device. BACKGROUND

[0002] The solidification of the coating of the aluminum part is a common processing procedure in the processing of the aluminum part. The existing solidification device heats the coating sprayed on the surface of the aluminum part to a molten state by hot air heating or infrared heating and then cools it down to fix the coating on the surface of the aluminum part. However, there are some problems in actual use of the assembly line. If the traditional hot air heating solidification device is used for solidification, the hot air with strong wind force will blow some coating away when the aluminum part enters the solidification device because the adhesion of the coating to the surface of the aluminum part is not strong enough. First, the blown coating will produce smoke dust in the air. Second, the position of the coating on the surface of the aluminum part will change, which will make the thickness of the coating uneven and reduce the effect of spraying. Reducing the wind force will reduce the heating effect and slow down the heating efficiency. The existing technology also has some devices that do not directly contact the aluminum part with hot air but blow hot air to other directions to indirectly heat the aluminum part by reflection or heat transfer. However, this way will cause great heat loss. If the infrared heating solidification device is used for solidification, there will be dead angles where light cannot be irradiated, which will cause incomplete heating. CONTENT OF THE UTILITY MODEL

[0003] To solve the above problems, the utility model provides an aluminum profile surface coating solidification device, which comprises a suspension conveying chain and a solidification bin. The suspension conveying chain passes through the solidification bin. The suspension conveying chain is connected with an aluminum part. The solidification bin is provided with a hot air assembly and an infrared heating assembly. The infrared heating assembly comprises infrared heating pipes, which are arranged on both sides of the aluminum part to irradiate the aluminum part. Preferably, the infrared heating pipes are fixed on two side walls of the solidification bin parallel to the suspension conveying chain. The hot air heating assembly comprises a variable frequency fan and an electric heating wire. The variable frequency fan is connected with an air outlet. The air outlet is provided with a flow valve. The air outlet is opposite to the connection between the suspension conveying chain and the aluminum part. The solidification bin is connected with an air extraction assembly.

[0004] The variable frequency fan and the flow valve are used to adjust the wind force of the hot air assembly. The air extraction assembly is used to extract the gas evaporated from the coating out of the solidification bin to prevent the gas from leaking and polluting the air in the workshop.

[0005] Preferably, a plurality of arrayed infrared heating pipes are arranged on both sides of the aluminum part. The plurality of infrared heating pipes can make the heating effect better. The arrayed distribution can make the heating more uniform.

[0006] The infrared heating tube should be set in a position so that the entire outer surface of the aluminum part can receive light as much as possible. A single infrared heating tube can be set horizontally or vertically. If a single infrared heating tube is set horizontally, the array composed of multiple infrared heating tubes is arranged in the vertical direction. If the infrared heating tube is set vertically, the array composed of multiple infrared heating tubes is arranged in the horizontal direction.

[0007] Preferably, the infrared heating tubes on both sides of the aluminum part are symmetrical to each other based on the aluminum part, that is, the infrared heating tubes are arranged relative to each other, and the longitudinal plane where the multiple infrared heating tubes are located is parallel to the longitudinal plane where the suspension conveyor chain is located. The relative arrangement can make the two surfaces of the aluminum part have the same heating effect.

[0008] Preferably, the length of the infrared heating tube is the same as the length of the hanging conveyor chain in the curing chamber, or the length of the infrared heating tube is the same as the length of the aluminum part and is parallel to the hanging conveyor chain. The above arrangement can ensure that each part of the aluminum part is at the same distance from the infrared heating tube, which is conducive to uniform heating of the surface coating of each part of the aluminum part.

[0009] Preferably, a focusing cover is provided on the infrared heating tube to reduce light beam dispersion, so that more infrared rays are irradiated on the surface of the aluminum part, thereby reducing heat loss.

[0010] Preferably, a reflective plate is provided in the curing chamber, and the reflection point of the reflective plate is located on the aluminum part, which reflects the light that is not irradiated by the infrared heating tube onto the aluminum part again. By utilizing the reflection principle, the parts of the aluminum part that cannot be directly irradiated can receive infrared rays again, thereby reducing the blind angle of irradiation and improving the heating efficiency.

[0011] Preferably, the hot air component also includes a hot air channel, the variable frequency fan and the air outlet are both connected to the hot air channel, and the heating wire is located in the hot air channel, so that the wind blown out by the variable frequency fan is transmitted in a direction through the hot air channel, reducing the divergence of wind force, improving the utilization rate of wind force, and saving resources.

[0012] The exhaust component is connected to the exhaust gas treatment system to treat the exhaust gas evaporated from the paint to prevent the exhaust gas from causing air pollution.

[0013] The position where the hanging conveyor chain enters the curing chamber is the entrance, and the position where the hanging conveyor chain leaves the curing chamber is the exit. Both the entrance and the exit are equipped with shading components to prevent the leaked infrared rays from damaging the workers' eyes.

[0014] The shading component includes shading fluff and shading plates. The shading fluff is arranged on the upper part of the entrance or exit to form a semi-enclosed structure for the hanging conveyor chain; the shading plate is located below the shading fluff and covers the entrance or exit to prevent light from leaking out of the curing chamber, and the shading plate is hinged to the outer wall of the curing chamber; shading fluff is used at the hanging conveyor chain to block the gaps. The soft nature of the shading fluff can make the shading fluff in close contact with the hanging conveyor chain, which can perfectly block the gaps at the hanging conveyor chain. However, shading fluff cannot be used at the aluminum parts because the aluminum parts have a coating on the surface. Therefore, shading plates or other shading parts with the same effect are used. The shading plate can also be set in other ways. The setting of the shading plate can neither hinder the hanging conveyor chain from transporting aluminum parts nor allow infrared rays in the curing chamber to leak. Any installation method that meets this condition is acceptable.

[0015] The beneficial effects of the present invention are:

[0016] 1. Use the infrared heating component and the hot air component to heat together, set the hot air component at the heating dead corner of the infrared heating component, and use the hot air component to assist in heating. At this time, the hot air component only needs to assist in heating the dead corner position, the heating area is small, and the heat loss on the heating path is small. Therefore, there is no need for too strong wind force. The heating wind force can be adjusted under the joint action of the frequency conversion fan and the flow valve, making the wind force blown out of the air outlet softer, which solves the drawbacks of the existing technology and will not affect the curing effect.

[0017] 2. Shading components are installed at the entrance and exit to prevent infrared light from leaking out of the curing chamber, thus avoiding light pollution. BRIEF DESCRIPTION OF THE DRAWINGS
