[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The embodiment of the present application discloses a device for pre-cleaning the surface of a car door panel powder spraying. Figure 1-4, a pre-cleaning device for powdering the surface of an automobile door panel comprises a cleaning chamber 1, a fan 11, a support frame 3 and a track conveyor belt 5, the interior of the track conveyor belt 5 is fixedly connected with a plurality of hooks 6 at equal intervals, and a car door fixing plate 7 is provided under the plurality of hooks 6, the cleaning chamber 1 is arranged on both sides of the plurality of car door fixing plates 7, the interior of the cleaning chamber 1 is fixedly connected with a support platform 2, the support platform 2 is provided with two, the two support platforms 2 are located on both sides of the plurality of car door fixing plates 7, the interior of the support platform 2 is fixedly plugged with a plurality of nozzles 4, and the outlet ends of the plurality of nozzles 4 extend to one side close to the car door fixing plate 7, the fan 11 is provided with two, the two fans 11 are respectively located on both sides of the cleaning chamber 1, the outlet ends of the two fans 11 are fixedly connected with a plurality of air ducts 41, and one end of the plurality of air ducts 41 is respectively connected to the inlet ends of the plurality of nozzles 4 on the two support platforms 2, the support frame 3 is provided with two, the two support frames 3 are respectively fixedly connected to the two support platforms 2, and the two support frames 3 are provided with a guide assembly 8 on one side close to the support platform 2;

[0025] In this way, during the implementation process, the automobile door panel needs to remove debris on the surface of the automobile door panel during the powder spraying process, so as to increase the adhesion of the powder spraying to the automobile door panel and increase the aesthetics of the finished product after the automobile door panel is heated in the later stage. The worker will first fix the automobile door panel on the automobile door fixing plate 7. Both sides of the automobile door fixing plate 7 can fix the automobile door panel. The track conveyor belt 5 will transport the automobile door fixing plate 7 under the hook 6, and the automobile door fixing plate 7 will drive the automobile door panel to pass through the cleaning chamber 1;

[0026] When the automobile door fixing plate 7 enters the cleaning chamber 1, the fan 11 will start and spray high-pressure gas through the air duct 41 and the nozzle 4. The high-pressure gas will come into contact with the automobile door fixing plate 7 passing by. When the high-pressure gas comes into contact with the automobile door panel, the debris on the surface of the automobile door panel will be blown off. The support platform 2 will support the multiple nozzles 4. By increasing the number of nozzles 4, the contact area between the high-pressure gas and the automobile door panel is increased, thereby improving the cleaning efficiency of the automobile door panel surface.

[0027] When the hook 6 passes through the support platform 2, the guide assembly 8 will limit the hook 6, reduce the shaking of the hook 6, increase the stability of the car door fixing plate 7 under the hook 6 during movement, and make the car door panel on the surface of the car door fixing plate 7 more stably contact with the high-pressure gas, thereby improving the cleaning efficiency.

[0028] Among them, one side of the two support frames 3 is fixedly connected with a support plate 31, and the lower parts of the two support plates 31 are fixedly connected to the outer walls of the two support platforms 2 respectively. The support plates 31 are perpendicular to one side of the outer wall of the support plates 31. The support frame 3 increases the structural strength of the connection with the support platform 2 through the support plate 31, thereby increasing the stability of the support frame 3 in supporting the guide assembly 8.

[0029] Preferably, the hook 6 is perpendicular to the bottom of the track conveyor belt 5, and one end of the hook 6 extends upward after passing through the car door fixing plate 7. The contact position between the hook 6 and the car door fixing plate 7 is square, and the inner wall of the car door fixing plate 7 will fit with the outer wall of the hook 6, thereby increasing the stability of the contact between the hook 6 and the car door fixing plate 7. The upward extension of the hook 6 prevents the car door fixing plate 7 from falling off during the movement.

[0030] Specifically, the two guide assemblies 8 are located on both sides of the multiple hooks 6. The two guide assemblies 8 each include a fixed column 81 and a guide plate 84. Two fixed columns 81 are provided. One end of the two fixed columns 81 is fixedly connected to the outer wall of one side of the support frame 3. The other side of the two fixed columns 81 is fixedly connected to a spring telescopic column 82. One end of the two spring telescopic columns 82 is rotatably connected to a hinge seat 83. One side of the guide plate 84 is fixedly connected to the two hinge seats 83. The guide plate 84 extends toward the side close to the hook 6.

[0031] The two guide components 8 will be located on both sides of the car door fixing plate 7 to limit the hook 6. When the hook 6 guides the component 8, the hook 6 will first contact the guide plate 84. The guide plate 84 changes its extension position through the spring telescopic column 82 supported by the rear, so that the two sides of the hook 6 are in contact with the outer wall of the guide plate 84, which is used to reduce the swinging amplitude of the guide components 8 to both sides during the movement of the hook 6, increase the stability of the car door fixing plate 7 below, and reduce the risk of collision between the car door fixing plate 7 and the support platform 2 and the nozzle 4 by controlling the swing amplitude of the car door fixing plate 7. The spring telescopic column 82 changes the contact angle between the guide plate 84 and the hook 6 through the hinge seat 83, increases the contact surface between the guide plate 84 and the hook 6, and increases the stability of the hook 6.

[0032] More specifically, one side of the two guide plates 84 is fixedly connected to a tilting platform 85, and the inner wall of the tilting platform 85 extends obliquely toward the side close to the entrance of the cleaning bin 1. When the hook 6 passes through the guide plate 84, the tilting platform 85 will first contact the hook 6. Through the guidance of the tilting platform 85, the risk of collision between the hook 6 and the guide plate 84 is reduced, so that the guide plate 84 can slide smoothly to both sides of the hook 6.

[0033] Furthermore, during the implementation process, the surfaces of the two guide plates 84 and the two tilting platforms 85 are provided with ball bearings 86, and there are multiple ball bearings 86. When the hook 6 contacts the guide plates 84 and the tilting platforms 85, the ball bearings 86 will reduce the friction between the outer wall of the hook 6 and the guide plates 84 and the tilting platforms 85.

[0034] The implementation principle of the device for pre-cleaning the surface of a car door panel powder spraying according to the embodiment of the present application is as follows: during the powder spraying process, the car door panel needs to be cleaned of debris on the surface of the car door panel in order to increase the adhesion of the powder spraying to the car door panel and increase the aesthetics of the finished product after the car door panel is heated in the later stage. The worker will first fix the car door panel on the car door fixing plate 7. Both sides of the car door fixing plate 7 can fix the car door panel. The track conveyor belt 5 will transport the car door fixing plate 7 under the hook 6. The car door fixing plate 7 will drive the car door panel to pass through the cleaning chamber 1. When the car door fixing plate 7 enters the cleaning chamber 1, the fan 11 will start and pass through the air duct 41 and The nozzle 4 sprays high-pressure gas, and the high-pressure gas will come into contact with the passing car door fixing plate 7. When the high-pressure gas comes into contact with the car door panel, the debris on the surface of the car door panel will be blown off. The support platform 2 will support multiple nozzles 4. By increasing the number of nozzles 4, the contact area between the high-pressure gas and the car door panel is increased, and the cleaning efficiency of the car door panel surface is increased. When the hook 6 passes through the support platform 2, the guide component 8 will limit the hook 6, reduce the shaking of the hook 6, and increase the stability of the car door fixing plate 7 under the hook 6 during the movement, so that the car door panel on the surface of the car door fixing plate 7 is in more stable contact with the high-pressure gas, thereby improving the cleaning efficiency.
