Description

Technical Field

[0001] The present invention relates to a painting and drying device for bus processing, belonging to the technical field of bus processing equipment. Background Art

[0002] Among the main components of a bus, those that need to be painted and baked include the body surface, roof, doors, front and rear fenders, front and rear bumpers, trunk lid, etc. Specifically, the painting and baking parts of a bus mainly include: ‌Body surface‌: It includes each panel of the body, such as the hood (engine cover), roof, front and rear fenders, doors, etc.

[0003] ‌Roof‌: The roof part needs to be painted and baked to ensure the unity and beauty of the overall appearance.

[0004] ‌Doors‌: Each door needs to be painted and baked separately to ensure the quality and appearance of each door are consistent.

[0005] ‌Front and rear fenders‌: The fenders located at the front and rear of the vehicle also need to be painted and baked to maintain the overall coordination of the body.

[0006] ‌Front and rear bumpers‌: As important parts of the body, the front bumper and rear bumper also need to be painted and baked.

[0007] ‌Trunk lid‌: The trunk lid (or tailgate) also needs to be painted and baked.

[0008] The painting and baking process of these components usually includes the following steps: ‌Pretreatment‌: The surface of the components is treated for rust removal, degreasing, dust removal, etc. to ensure the painting quality.

[0009] ‌Painting‌: According to the specific requirements of the components, primer, intermediate coat and top coat are sprayed. After each layer of painting, drying treatment is required to ensure that the paint layer adheres firmly and has a uniform color.

[0010] ‌Drying‌: After painting, the components are placed in a paint baking room for drying treatment. Through uniform hot air and precise temperature control, the paint surface is ensured to be completely cured.

[0011] The drying method used in a certain bus processing plant is that after different components are painted, they are manually placed on the racks in the paint baking room for drying, and different components are baked together during the drying process. However, different components use different paints, and the baking temperature and humidity are also different. If all are baked together, the drying effect will be poor, thus affecting the processing quality of the bus. Summary of the Invention

Detailed Description of the Embodiment

[0026] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments. Embodiment

[0027] A passenger car processing spraying and drying device, as Figure 1 shown, includes 6 partition plates 6 arranged vertically inside the paint baking room. The partition plates 6 are resin heat insulation plates with low thermal conductivity and good compressive strength. Upper sliding grooves 4 and lower sliding grooves 5 are correspondingly arranged on the top wall 3 and the ground 1 of the paint baking room. Clamping blocks 7 are respectively arranged at the upper and lower ends of the partition plates 6 and are matched with the upper sliding grooves 4 and the lower sliding grooves 5. The clamping blocks 7 are clamped into the upper sliding grooves 4 and the lower sliding grooves 5 and can only slide left and right along the upper sliding grooves 4 and the lower sliding grooves 5. The partition plates 6 are slidably and hermetically connected to the paint baking room.

[0028] As Figure 1 shown, electric heating plates 8 are respectively fixed on the left and right sides of the partition plates 6, and electric heating plates 8 are also fixed on the left and right side walls 2 of the paint baking room. Seven air circulation fans 9 are arranged in sequence at the top of the paint baking room. The air inlets of the air circulation fans 9 are communicated with the inner top of the paint baking room, as Figure 1 , Figure 2As shown, the air outlet of the air circulation fan 9 is connected to the bottom of the paint baking room through the circulation air duct 13. The part of the circulation air duct 13 located at the top of the paint baking room is connected to the outside through a three-way valve 12. A temperature sensor 10 and a humidity sensor 11 are arranged on the part of the circulation air duct 13 between the air circulation fan 9 and the three-way valve 12. The temperature sensor 10 is electrically connected to the electric heating plate 8 of the corresponding compartment through a controller, and the upper limit value and the lower limit value of the temperature in the compartment are set through the controller.

[0029] The air circulation fan 9 is used to realize the internal circulation of the air inside the compartment, realize the uniform heating inside the compartment, improve the quality of drying, and accelerate the drying rate. At the same time, the temperature sensor 10 continuously detects the temperature of the air inside the compartment. When the temperature inside the compartment is lower than the set lower limit value, the temperature sensor 10 controls the corresponding electric heating plate 8 to heat through the controller. When the temperature inside the compartment is higher than the set upper limit value, the temperature sensor 10 turns off the corresponding electric heating plate 8 through the controller.

[0030] At the same time, the humidity sensor 11 continuously detects the humidity inside the compartment. As Figure 1 、 Figure 3 shown, the bottom of the paint baking room is connected to the outside through an air inlet duct 14. An automatic valve 15 and a desiccant box 16 are arranged on the air inlet duct 14. The humidity sensor 11 is electrically connected to the three-way valve 12 and the automatic valve 15 through a controller. The upper limit value and the lower limit value of the humidity in the compartment are set through the controller. When the humidity sensor 11 detects that the humidity inside the paint baking room exceeds the set upper limit value, the humidity sensor 11 controls the outlet end of the three-way valve 12 to be connected to the outside through the controller, and the automatic valve 15 is opened. At this time, the air circulation fan 9 pumps out the wet air inside the compartment, and at the same time, the outside air enters the compartment after being dried by the desiccant box 16. When the humidity sensor 11 detects that the humidity inside the paint baking room is lower than the set lower limit value, the humidity sensor 11 controls the outlet end of the three-way valve 12 to be connected to the circulation air duct 13 through the controller, and the automatic valve 15 is closed, and the air inside the compartment circulates internally.

[0031] In this embodiment, the desiccant inside the desiccant box 16 needs to be replaced regularly to ensure the drying effect.

[0032] In this embodiment, the paint baking room is divided into different compartments by the partition board 6, and the temperature and humidity of each compartment can be independently controlled. By sliding the partition board 6, the size of each compartment can be set separately according to needs. For example, the size of the compartment can be set differently according to the type of parts, or the size of the compartment can be adjusted according to the quantity of the same type of products. The various parts of the passenger car are classified and dried separately, so as to improve the quality and efficiency of drying after spraying of the various parts of the passenger car, thus improving the processing quality of the passenger car and saving energy.

[0033] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims described above.
