Technical Field
[0001] This utility model belongs to the field of automotive parts manufacturing technology, specifically a spraying device for automotive parts. Background Technology
[0002] Spraying equipment refers to devices that apply surface coatings to metal or non-metal automotive parts. Existing spray guns can be used with spraying robots to specifically coat automotive parts with paint, cover damaged areas, or change their color.
[0003] Traditional painting equipment requires pre-treatment of the car parts' surfaces before painting them. This can be done by sanding, polishing, or removing the existing paint. Then, the prepared paint is sprayed directly onto the car parts' surfaces.
[0004] Existing spraying equipment sprays paint directly onto the surface of automotive parts. During the spraying process, it has been found that dust and other floating particles exist in the air around the automotive parts, which easily adhere to the undried paint surface, thus causing paint contamination.
[0005] To address the aforementioned issues, a painting device for automotive parts is proposed. Utility Model Content
[0006] To overcome the shortcomings of existing technologies, this utility model proposes a spraying device for automotive parts.
[0007] The technical solution adopted by this utility model to solve its technical problem is: a spraying device for automotive parts, including a trailer board; a baffle fixedly connected to the top of the trailer board; a sealing cloth fixedly connected to the side wall of the baffle; a baffle strip fixedly connected to the side wall of the sealing cloth; a first spring fixedly connected to the side wall of the baffle strip; the other end of the first spring fixedly connected to the baffle; a paint inlet fixedly connected to the side wall of the baffle; and the paint inlet penetrating through the baffle in the middle. By setting a retractable sealing cloth to surround the paint inlet output end and automotive parts such as car doors, the problem of dust and other floating objects in the air remaining on the car door, which affects the spraying effect, can be reduced; at the same time, it can reduce the adhesion of external dust to the car door when the paint on the car door is not dry, and reduce the problem of contamination of the car door spraying area.
[0008] Preferably, the baffle is fixedly connected to a rubber strip; a second spring is fixedly connected to the side wall of the baffle; the second spring is disposed inside the rubber strip; multiple second springs are disposed on the baffle; by providing a rubber strip supported by a second spring on the baffle, the rubber strip can be made to fit different shaped car doors, further reducing the problem of paint surface contamination caused by a large amount of dust and other floating matter in the surrounding area when car doors and other automotive parts are being painted.
[0009] Preferably, the baffle has an air inlet in the middle; the baffle also has an air outlet in the middle; a filter screen is fixedly connected to the side wall of the baffle; the filter screen covers the air inlet; an electric motor is fixedly connected to the side wall of the baffle; and the electric motor is connected to the air outlet. By providing an air inlet and a filter screen in the middle of the baffle, the problem of dust and floating debris contaminating the car door can be further reduced, while also achieving the goal of quickly drying the paint.
[0010] Preferably, a heating wire is fixed to the inner wall of the air inlet; multiple heating wires are provided. Heating by the heating wires allows a large amount of outside air to enter the painted surface, generating hot air that quickly dries the surface and reduces dust and other floating debris contamination of the car door.
[0011] Preferably, a heat lamp is fixedly connected to the side wall of the baffle; a reflector is fixedly connected to the center of the heat lamp; the heat lamp is positioned on the same side as the baffle and the sealing cloth. By using the heat lamp and reflector to dry the car door, the problem of dust and other floating particles remaining on the car door and affecting the painting effect can be reduced; at the same time, it can reduce the adhesion of external dust to the car door while the paint is still wet, reducing the problem of contamination of the car door painting area.
[0012] Preferably, the sidewall of the baffle is fixedly connected to an eaves; the eaves and the sealing cloth are located on the same side; the eaves are located at the top of the air inlet; the eaves are inclined. The combination of the baffle and the sealing cloth effectively prevents large particles from entering, protecting the interior doors from damage.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0026] A spraying device for automotive parts, such as Figure 1As shown, the device includes a trailer board 1; a baffle 11 is fixedly connected to the top of the trailer board 1; a sealing cloth 12 is fixedly connected to the side wall of the baffle 11; a baffle strip 14 is fixedly connected to the side wall of the sealing cloth 12; a first spring 13 is fixedly connected to the side wall of the baffle strip 14; the other end of the first spring 13 is fixedly connected to the baffle 11; a paint inlet 15 is fixedly connected to the side wall of the baffle 11; and the paint inlet 15 is disposed through the baffle 11 in the middle. During operation, large automotive parts, such as car doors, are first placed upright and secured. Then, the trailer plate 1 is moved closer to the automotive parts. At this time, the baffle strip 14 on one side of the baffle 11 will fit against the automotive parts. As the trailer plate 1 continues to move, the baffle strip 14 will squeeze the sealing cloth 12 and the first spring 13. At this time, the sealing cloth 12 and the first spring 13 will contract, achieving a stable fit between the baffle strip 14 and the car door. Then, the paint inlet 15 is connected to the paint supply equipment, so that paint can be supplied into the paint inlet 15 and then sprayed out from the end of the paint inlet 15 to paint the car doors and other automotive parts. By setting a retractable sealing cloth 12 to surround the output end of the paint inlet 15 and the car doors and other automotive parts, the problem of dust and other floating objects in the air remaining on the car door and affecting the painting effect can be reduced. At the same time, it can reduce the adhesion of external dust to the car door when the paint on the car door is not dry, and reduce the problem of contamination of the car door painting area.
[0027] In one embodiment of this utility model, a rubber strip 2 is fixedly connected to the baffle 14; a second spring 21 is fixedly connected to the side wall of the baffle 14; the second spring 21 is disposed inside the rubber strip 2; multiple second springs 21 are disposed on the baffle 14; during operation, when the baffle 14 is attached to a car door or other automotive parts, the rubber strip 2 will be spaced between the car door and the baffle 14. When the baffle 14 squeezes the car door, the rubber strip 2 deforms, and the second spring 21 inside the rubber strip 2 supports the rubber strip 2. At this time, the rubber strip 2 can effectively fill the gap between the baffle 14 and the car door, thereby further reducing the problem of external dust and other floating objects entering the sealing cloth 12 and the car door; by providing a rubber strip 2 supported by the second spring 21 on the baffle 14, the rubber strip 2 can be attached to car doors of different shapes, further reducing the problem of the painted surface being contaminated due to a large amount of dust and other floating objects in the surrounding area when the car door and other automotive parts are being painted.
[0028] In one embodiment of this utility model, an air inlet 3 is provided in the middle of the baffle 11; an air outlet 31 is provided in the middle of the baffle 11; a filter screen 32 is fixedly connected to the side wall of the baffle 11; the filter screen 32 covers the position of the air inlet 3; an electric motor 33 is fixedly connected to the side wall of the baffle 11; the electric motor 33 is connected to the air outlet 31. During operation, firstly, the car door or automotive parts are fixed to the baffle 11. The design of the baffle 11 ensures that the parts remain stable during the spraying process, preventing movement and shaking. External air enters the sprayed area through the filtration of the rubber strip 2 and the air inlet 3, accelerating the drying of the paint and preventing external dust and floating objects from entering the car door. Then, the generated waste air is discharged through the air outlet 31 and the electric motor 33. With the air inlet 3 and filter screen 32 in the middle of the baffle 11, the filtration effect of the filter screen 32 further reduces the pollution of the car door by dust and floating objects, while also achieving the purpose of rapid paint drying.
[0029] In one embodiment of this utility model, heating wires 4 are fixedly connected to the inner wall of the air inlet 3; multiple heating wires 4 are arranged. During operation, in order to achieve rapid paint drying, many heating wires 4 are arranged inside the air inlet 3 to allow the paint to dry quickly, thereby reducing the pollution of the painted surface by dust or floating objects generated from the outside. Through the heating of the heating wires 4, when a large amount of outside air enters the painted surface, the hot air generated allows the surface to dry quickly, reducing the pollution of the car door by dust and floating objects.
[0030] In one embodiment of this utility model, a heat lamp 5 is fixedly connected to the side wall of the baffle 11; a reflector 51 is fixedly connected to the middle of the heat lamp 5; the heat lamp 5 is arranged on the same side as the baffle 11 and the sealing cloth 12. During operation, when the car door approaches the baffle 11 and the sealing cloth 12, the car door will squeeze and adhere to the sealing cloth 12. When the car door is adhered to the sealing cloth 12, the heat lamp 5 and the reflector 51 will dry the sprayed paint surface, preventing dust and atmospheric particles from contaminating the car door. By drying the car door with the heat lamp 5 and the reflector 51, the problem of dust and other floating particles remaining on the car door, thus affecting the spraying effect, can be reduced. Simultaneously, it can reduce external dust adhering to the car door while the paint is still wet, reducing the problem of contamination of the sprayed area.
[0031] In one embodiment of this utility model, an eaves 6 is fixedly connected to the side wall of the baffle 11; the eaves 6 and the sealing cloth 12 are located on the same side; the eaves 6 are located at the top of the air inlet 3; the eaves 6 are inclined. During operation, when external air enters the device through the air inlet 3, the eaves 6 guide its flow, preventing direct impact on sensitive internal components. The baffle 11 provides protection, preventing large particles of impurities from directly entering the device. The sealing cloth 12 further seals, ensuring that only clean air or liquid enters, maintaining a clean internal environment. The combination of the baffle 11 and the sealing cloth 12 effectively prevents large particles of impurities from entering, protecting the internal doors from damage. The sealing cloth 12 significantly improves the device's sealing performance, preventing external dust, moisture, and other impurities from entering, maintaining a dry and clean internal environment.
[0032] Working principle: First, large automotive parts, such as car doors, are placed upright and secured. Then, the trailer plate 1 is moved closer to the automotive parts. At this time, the baffle strip 14 on one side of the baffle 11 will fit against the automotive parts. As the trailer plate 1 continues to move, the baffle strip 14 will compress the sealing cloth 12 and the first spring 13. At this time, the sealing cloth 12 and the first spring 13 will contract, achieving a stable fit between the baffle strip 14 and the car door. Then, the paint inlet 15 is connected to the paint supply equipment, thus enabling the delivery of oil into the paint inlet 15. Paint is sprayed from the end of the paint inlet 15 to coat automotive parts such as car doors. When the retaining strip 14 is attached to the car door or other automotive parts, the rubber strip 2 is spaced between the car door and the retaining strip 14. When the retaining strip 14 presses against the car door, the rubber strip 2 deforms, and the second spring 21 inside the rubber strip 2 supports the rubber strip 2. At this time, the rubber strip 2 can effectively fill the gap between the retaining strip 14 and the car door, thereby further reducing the problem of external dust and other floating objects entering the sealing cloth 12 and the car door. First, the car door or automotive parts are fixed to the baffle 11. The design of the baffle 11 ensures that the parts remain stable during the spraying process, preventing movement and shaking. External air enters the sprayed area through the filter of the rubber strip 2 and the air inlet 3, accelerating the drying of the paint and preventing external dust and floating objects from entering the car door. Then, the generated exhaust air is discharged through the air outlet 31 and the electric motor 33. To achieve rapid paint drying, many heating wires 4 are arranged inside the air inlet 3 to allow the paint to dry quickly, reducing the pollution of the sprayed surface by external dust or floating objects. When the car door is close to the baffle 11 and the sealing cloth 12, the car door will squeeze and adhere to the sealing cloth 12. When the car door is adhered to the sealing cloth 12, the heat lamp 5 and the reflector 51 will dry the sprayed paint surface to prevent dust and floating objects in the atmosphere from contaminating the car door. When external air enters the device through the air inlet 3, the eaves 6 will guide its flow to avoid direct impact on sensitive internal components. The baffle 11 serves a protective function, preventing large particles of impurities from directly entering the device. The sealing cloth 12 further seals the interior, ensuring that only clean air or liquid enters, thus maintaining a clean internal environment.
