Description

Technical Field

[0001] This utility model relates to a spray painting device, and more particularly to a spray painting device for plastic products. Background Technology

[0002] Plastic product painting equipment typically refers to mechanical equipment specifically designed for surface coating treatment of plastic materials. This type of equipment enhances the appearance and functional characteristics of plastic parts by uniformly spraying paint onto their surfaces, such as improving aesthetics, durability, and corrosion resistance.

[0003] Traditional spraying equipment typically uses spray guns for spraying operations. While it offers a certain degree of automation, the following problems exist during the spraying process:

[0004] 1. Traditional spray guns have a relatively simple structure, making it difficult to flexibly adjust the position of the spray gun according to products of different sizes and spraying requirements. The distance of the spray gun directly affects the thickness and quality of the coating, easily leading to inconsistent paint film thickness, especially when processing workpieces with complex shapes;

[0005] 2. Traditional equipment usually requires manual operation and intervention, which not only reduces production efficiency but also increases the impact of human factors on coating quality. Utility Model Content

[0006] To overcome the aforementioned shortcomings, the technical problem to be solved is to provide a plastic product spray painting equipment.

[0007] The technical implementation scheme of this utility model is as follows: a plastic product spraying equipment, including a support assembly, a support platform, a first screw, a sliding platform, a support frame, a second motor, a second screw, a connecting frame, a spray nozzle, and a feeding assembly. The support assembly is connected to the left side of the support platform. The first screw is rotatably connected to the upper side of the support platform. The sliding platform is threadedly connected to the first screw. The sliding platform is slidably connected to the support platform. The support frame is connected to the top of the sliding platform. The second motor is installed on the top of the sliding platform. The second screw is connected to the output shaft of the second motor. The second screw is a bidirectional screw, that is, one end is a right-hand thread and the other end is a left-hand thread. The connecting frame is threadedly connected to the lower end of the second screw. The connecting frame is slidably connected to the support frame. Spray nozzles are symmetrically connected to the connecting frame. The feeding assembly is provided on the support frame.

[0008] As a further preferred embodiment, the support assembly includes a base, a first motor, a rotating platform, and a limiting component. The base is connected to the left side of the support platform, and the first motor is installed at the top inside the base. The output shaft of the first motor passes through the top of the base and is connected to the rotating platform. A limiting component is provided at the rear of the base.

[0009] As a further preferred option, the limiting assembly includes a fixed frame, an electric push rod, and a connecting plate. The fixed frame is connected to the rear side of the base, and the electric push rod is mounted on the upper side of the fixed frame. The connecting plate is rotatably connected to the telescopic rod of the electric push rod, and the connecting plate is located directly above the rotating table.

[0010] As a further preferred embodiment, the feeding assembly includes a connecting pipe, a housing, and a feed inlet. The housing is threadedly connected to the upper end of the first screw, and the housing is slidably connected to the support frame. Connecting pipes are symmetrically connected to the top of the housing, and the lower ends of the connecting pipes are connected to the nozzles respectively. The feed inlet is connected to the front side of the housing.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example: A plastic product spray painting equipment, such as Figures 1-4 As shown, the system includes a support assembly, a support platform 4, a first screw 5, a sliding table 6, a support frame 7, a second motor 9, a second screw 10, a connecting frame 11, a nozzle 12, and a feeding assembly. The support assembly is connected to the left side of the support platform 4. The first screw 5 is rotatably connected to the upper side of the support platform 4. The sliding table 6 is threadedly connected to the first screw 5. The sliding table 6 is slidably connected to the support platform 4. The support frame 7 is connected to the top of the sliding table 6. The second motor 9 is bolted to the top of the sliding table 6. The second screw 10 is connected to the output shaft of the second motor 9. The second screw 10 is a bidirectional screw, i.e., one end is a right-hand thread and the other end is a left-hand thread. The connecting frame 11 is threadedly connected to the lower end of the second screw 10. The connecting frame 11 is slidably connected to the support frame 7. The nozzles 12 for spraying paint are symmetrically connected to the front and rear of the connecting frame 11. The support frame 7 is equipped with a feeding assembly for supplying paint.

[0022] like Figure 1 and Figure 4 As shown, the support assembly includes a base 1, a first motor 2, a rotating platform 3, and a limiting component. The base 1 is connected to the left side of the support platform 4. The first motor 2 is installed inside the top of the base 1 by bolts. The output shaft of the first motor 2 passes through the top of the base 1 and is connected to the rotating platform 3 for driving the plastic product to rotate. A limiting component is provided on the rear side of the base 1.

[0023] like Figure 1 and Figure 4 As shown, the limiting assembly includes a fixed frame 16, an electric push rod 17, and a connecting plate 18. The fixed frame 16 is welded to the rear side of the base 1. The electric push rod 17 is installed on the upper side of the fixed frame 16. The connecting plate 18 for limiting plastic products is rotatably connected to the telescopic rod of the electric push rod 17. The connecting plate 18 is located directly above the rotating table 3.

[0024] like Figure 3 As shown, the feeding assembly includes a pulley frame 8, a connecting pipe 13, a housing 14, and a feed inlet 15. The upper end of the first screw 5 is threadedly connected to the housing 14 for storing paint. The housing 14 is slidably connected to the support frame 7. The top of the housing 14 is symmetrically connected to the front and rear of the connecting pipe 13. The lower ends of the connecting pipe 13 are respectively connected to the spray nozzle 12. The front side of the housing 14 is connected to the feed inlet 15, and a plug is inserted into the feed inlet 15. The top of the support frame 7 is equipped with a pulley frame 8, and the two connecting pipes 13 are respectively limited on the pulley frame 8.

[0025] When painting plastic products, first remove the plug at the feed inlet 15, connect the outer pipe to the feed inlet 15, and inject paint into the housing 14. After injection, replace the plug at the feed inlet 15. Then, place the plastic product on the rotating table 3, start the electric push rod 17, and extend its telescopic rod to move the connecting plate 18 downward, so that the connecting plate 18 contacts the plastic product, thereby limiting the plastic product. Plastic products of different heights and sizes can be placed on the rotating table 3. After placement, turn off the electric push rod 17, and then adjust the left and right positions of the spray head 12. Adjust the position according to the size of the plastic product and the required paint thickness. Rotating the first screw 5 forward or backward will move the sliding table 6 to the left or right, causing the nozzle 12 and feeding assembly on it to move accordingly. After determining the left and right position of the nozzle 12, start the first motor 2, the second motor 9, and the nozzle 12. The output shaft of the first motor 2 rotates, causing the rotating table 3 to rotate, thus rotating the plastic product and the connecting plate 18. The output shaft of the second motor 9 rotates, causing the second screw 10 to rotate, thus moving the connecting frame 11 and the nozzle 12 upward. Paint is drawn from the housing 14 and flows through the connecting pipe 13 into the nozzle 12, where it is sprayed onto the surface of the plastic product. As the plastic product rotates, the paint is evenly applied. When the second screw 10 rotates, causing the nozzle 12 to gradually move upwards, it simultaneously moves the housing 14 downwards along the support frame 7, bringing the two closer together. The upward movement of the nozzle 12 loosens one end of the connecting pipe 13, while the downward movement of the housing 14 causes the other end of the connecting pipe 13 to move downwards, ensuring the connecting pipe 13 is stably positioned on the pulley frame 8. When the second screw 10 rotates in the opposite direction, it drives... The connecting frame 11 and the housing 14 move away from each other. The output shaft of the second motor 9 rotates in both directions, which drives the nozzle 12 to move up and down through the second screw 10 to uniformly spray the plastic product. After the spraying is completed, the second motor 9 and the nozzle 12 are turned off, the nozzle 12 and the housing 14 are reset accordingly, and the first motor 2 is turned off to stop the plastic product from rotating. Then, the electric push rod 17 is controlled to extend and retract, driving the connecting plate 18 to move up and no longer press the plastic product, so that it can be unloaded and cured. The above operation can be used to spray paint other plastic products.

[0026] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model should be included within the scope of the claims of the present utility model.
