Specific implementation mode

[0019] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] The present utility model provides a technical solution: Refer to Figures 1-4 , a spraying tool for a long-shaped automotive interior part disclosed by the present utility model includes a connecting rod 1 fixedly installed on the moving end of a spraying tool slide rail of the long-shaped automotive interior part. A fixed plate 2 is fixedly installed at the bottom end of the connecting rod 1. A spraying mechanism 3 is provided on the bottom side of the fixed plate 2. A baffle 4 is provided on the right side of the fixed plate 2. The baffle 4 and the fixed plate 2 are connected by a connecting part 6. A discharging part 5 is provided on the bottom side of the baffle 4.

[0021] In this embodiment, when the improved spraying tool performs the spraying operation on the long-shaped automotive interior part, the spraying tool slide rail controls the spraying mechanism 3 to move uniformly from right to left at a specific height above the long-shaped automotive interior part through the connecting rod 1 and the fixed plate 2, so as to complete the spraying of the surface coating of each section of the long-shaped automotive interior part through the spraying mechanism 3. During the process of the spraying mechanism 3 performing the coating spraying operation, the baffle 4 can intercept the air flow and coating on the surface coating of the front section of the long-shaped automotive interior part. At the same time, the discharging part 5 diverts the intercepted air flow and coating by the baffle 4 into an external waste storage box for storage, while avoiding the dripping of the coating by the baffle 4 and at the same time avoiding the air flow passing over the baffle 4 from the gap between the bottom side of the baffle 4 and the long-shaped automotive interior part and blowing on the coating of the front section of the baffle 4, so as to avoid the surface of the front section of the long-shaped automotive interior part being attached with the coating and being blown by the air flow for a long time, resulting in a slight wrinkle of the coating on the surface of the long-shaped automotive interior part and affecting the spraying effect of the spraying tool on the long-shaped automotive interior part.

[0022] In a further preferred embodiment of the present utility model, as Figure 1 and Figure 2As shown in the figure, the spraying mechanism 3 includes a number of electric control spray heads 32. A shunt pipe 31 is fixedly installed on the bottom side of the fixing plate 2, and the bottom side of the shunt pipe 31 is arranged in an inclined shape. A number of electric control spray heads 32 are installed on the bottom side of the shunt pipe 31, and the feeding end of each electric control spray head 32 is inserted into the shunt pipe 31 and fixedly connected to the pipe wall of the shunt pipe 31. An interface 33 is provided on the side wall of the shunt pipe 31, and the discharging end of the interface 33 penetrates through the pipe wall of the shunt pipe 31 and is fixedly connected to the pipe wall of the shunt pipe 31;

[0023] In this embodiment, when the above spraying mechanism 3 performs the spraying operation on the long-shaped automotive interior parts, the discharging pipe of the spraying tool injects the paint into the shunt pipe 31 from the interface 33 and maintains the pressure in the discharging pipe at a set intensity. Subsequently, the electric control valve is opened, and the paint in the shunt pipe 31 is atomized and sprayed out from the electric control valve, so that the surface of the long-shaped automotive interior parts is covered with a relatively uniform layer of paint;

[0024] It should be noted that the discharging end of the main material pipe of the spraying tool for the long-shaped automotive interior parts is connected and installed with the feeding end of the interface 33.

[0025] In a further preferred embodiment of the present utility model, as Figure 2 shown, the distance between two adjacent electric control spray heads 32 is equal, and each electric control spray head 32 is arranged in an inclined shape. The distance between the discharging end of the electric control spray head 32 and the baffle 4 is greater than the distance between the feeding end of the electric control spray head 32 and the baffle 4;

[0026] In this embodiment, the number of opened electric control spray heads 32 is adjusted according to the width of the long-shaped automotive interior parts, so that the spraying width of the paint of the spraying mechanism 3 can be adjusted. Moreover, the paint discharged from the discharging end of the electric control valve is discharged obliquely to the left to avoid the rightward blowing air flow and the amount of paint.

[0027] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 3 shown, the discharging member 5 includes a cylinder 51. The baffle 4 is arranged in an arc-shaped plate shape. A feeding hole 52 is opened on the outer peripheral wall of the cylinder 51, and the bottom end of the baffle 4 is inserted into the feeding hole 52 and fixedly connected to the inner wall of the cylinder 51;

[0028] In this embodiment, the paint intercepted by the above baffle 4 slides along the baffle 4 and enters the fixed cylinder through the feeding hole 52 under the push of the air flow, so that the paint intercepted by the baffle 4 hardly drips from the baffle 4 onto the long-shaped automotive interior parts.

[0029] In a further preferred embodiment of the present utility model, as Figures 1-3As shown, two flexible tubes 53 are provided opposite to each other at both ends of the cylinder 51, and the feeding ends of each flexible tube 53 penetrate through the cylinder wall of the cylinder 51 and are fixedly connected to the cylinder wall of the cylinder 51. The bottom end of the inner wall of the flexible tube 53 is collinear with the bottom end of the inner wall of the cylinder 51;

[0030] In this embodiment, the discharging end of the flexible tube 53 is connected and installed to the feeding end of the pump body on the external waste storage box. During the process of spraying the coating on the long-shaped automotive interior parts by the spraying mechanism 3, the pump body on the external waste storage box starts to continuously suck the gas in the cylinder 51 into the external waste storage box through the flexible tube 53, and makes the cylinder 51 continuously form a negative pressure state. At this time, the gas above the cylinder 51 continuously flows into the cylinder 51 from the feeding hole 52 to supplement the lost gas in the cylinder 51, so that the intercepted air flow and coating directly flow into the round tube and are introduced into the external waste storage box through the flexible tube 53 for storage.

[0031] In a further preferred embodiment of the present utility model, as Figure 2 and Figure 4 shown, a card slot 61 with a T-shaped cross-section is provided at the middle position on the right side of the fixing plate 2. A clamping block 62 is provided in the card slot 61, and the part of the clamping block 62 located in the card slot 61 is in contact with the inner wall of the card slot 61. The right end of the clamping block 62 extends outside the card slot 61 and is fixedly connected to the baffle 4. A threaded rod 63 with a T-shaped cross-section is provided on the top side of the fixing plate 2. The bottom end of the threaded rod 63 is inserted into the clamping block 62 and is threadedly connected to the fixing plate 2 and the clamping block 62;

[0032] In this embodiment, when cleaning or replacing the baffle 4, first disconnect the connection between the flexible tube 53 and the feeding end of the pump body of the external waste storage box, reverse-rotate the threaded rod 63 to screw the threaded rod 63 out of the clamping block 62 to release the locked state of the clamping block 62, and then push the clamping block 62 by the baffle 4 to push the clamping block 62 out of the card slot 61, so that the baffle 4 can be removed from the fixing plate 2 for cleaning. If replacing the baffle 4, push the clamping block 62 on the new baffle 4 into the card slot 61 to complete the replacement of the new baffle 4. Finally, screw the bottom of the threaded rod 63 into the clamping block 62 to lock the position between the fixing plate 2 and the baffle 4, and connect the discharging end of the flexible tube 53 to the feeding end of the pump body of the external waste storage box, and the replacement of the baffle 4 is completed.

[0033] Working principle: When the spraying tool for the improved long-shaped automotive interior parts sprays the long-shaped automotive interior parts, the feeding pipe of the spraying tool continuously injects the coating into the shunt pipe 31 from the interface 33. Then, the coating in the shunt pipe 31 is atomized by the electric control spray head 32 and sprayed on the long-shaped automotive interior parts;

[0034] It should be noted that according to the need, the corresponding number of electric control spray heads 32 is started to adjust the spraying width of the spraying mechanism 3;

[0035] At the same time, the spray tool slide rail drives the fixed plate 2 to move back and forth, thereby driving the electric control nozzle 32 located on the top side of the long automobile interior decoration part from right to left at a uniform speed through the connecting pipe, the fixed plate 2 and the shunt pipe 31, so that the paint sprayed by the electric control nozzle 32 covers the long automobile interior decoration part;

[0036] During the process of coating spraying by the electronically controlled spray head 32, the pump body on the external waste storage box continuously sucks the gas in the cylinder 51 into the external waste storage box through the soft pipe 53, and the cylinder 51 continuously forms a negative pressure state. At this time, the gas above the cylinder 51 continuously flows into the cylinder 51 from the feed hole 52 to replenish the lost gas in the cylinder 51;

[0037] According to the above, during the movement of the electric-controlled nozzle 32, the paint and airflow sprayed from the electric-controlled nozzle 32 will not blow on the paint on the surface of the long automobile interior decoration part due to the obstruction of the baffle 4, and the airflow and paint moving toward the baffle 4 pass through the feed hole 52 along the inner wall of the baffle 4 into the cylinder 51, and are introduced into the external waste storage box for storage through the soft pipe 53;

[0038] When replacing the baffle 4, first release the connection between the soft tube 53 and the feed end of the external waste storage tank pump body, rotate the threaded rod 63 in the opposite direction to screw the threaded rod 63 out of the block 62, release the locked state of the block 62, then push the block 62 through the baffle 4, push the block 62 out of the slot 61, and then push the block 62 on the new baffle 4 into the slot 61 to complete the replacement of the new baffle 4, finally screw the bottom of the threaded rod 63 into the block 62 to lock the position between the fixed plate 2 and the baffle 4, and connect the discharge end of the soft tube 53 to the feed end of the external waste storage tank pump body, and the replacement of the baffle 4 is completed.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
