[0013] Beneficial effects
[0014] This utility model provides a surface treatment device for refrigerator top frame accessories. Compared with the prior art, it has the following advantages:
[0015] Firstly, when the third electric push rod is activated, its telescopic end drives the lifting block to slide up and down within the groove. The lifting block then drives the gear rod to move up and down. Since the gear rod meshes with the gear block on the connecting shaft, the up and down movement of the gear rod drives the connecting shaft to rotate, thereby allowing the paint spraying shell to be finely adjusted in angle. This makes it more accurately aligned with the surface of the accessory, and better paints the upper sidewall of the accessory. It achieves flexible adjustment of the paint spraying shell in terms of height, horizontal position, and angle, which can meet the painting needs of accessories with different shapes and positions. It allows the spray gun to be accurately aligned with various parts of the accessory, and is especially suitable for the complex-shaped refrigerator top frame. This improves the uniformity and quality of the spraying, and enhances the accuracy and quality of the paint spraying.
[0016] Secondly, this utility model loosens the locking bolt, manually rotates the adjusting rod, which drives the support shaft to rotate, thereby causing the mounting bracket and the clamped parts to flip. Then, tightening the locking bolt fixes the adjusting rod inside the support block, achieving the positioning of the parts.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a surface treatment device for refrigerator top frame accessories, including a support frame 1, on which a painting mechanism for surface treatment of refrigerator top frame accessories is provided, the painting mechanism including:
[0025] The flipping assembly includes a support frame 1 with a support shaft 2 rotatably connected inside. One end of the support shaft 2 is provided with a mounting bracket 201 connected by a locking assembly. The mounting bracket 201 is provided with a limiting clamp 301 connected by a telescopic assembly inside. A rubber block 302 is fixed to the clamping surface of the limiting clamp 301. Anti-drop blocks 303 are fixed to the upper and lower ends of the limiting clamp 301.
[0026] The adjustment component includes a slider 504 connected to the support frame 1 on one side via the support component, a connecting shaft 506 connected to the lower end of the slider 504 via a gear component, a paint shell 505 fixed to one end of the connecting shaft 506, and hot air units 4 on both sides of the upper end of the support frame 1, with an air guide shell 401 fixed to the output end of the hot air unit 4.
[0027] During or after the painting process, the hot air unit 4 is activated, and the generated hot air is guided to the surface of the accessory through the air guide housing 401. The hot air unit 4 and the air guide housing 401 set on both sides can achieve simultaneous drying of both sides of the accessory, further improving the drying efficiency. The model of the hot air unit 4 is AFC series.
[0028] One side of the paint spraying housing 505 is equipped with a flexible hose for connecting to the paint tank for paint input and spraying operations. This is existing technology and will not be elaborated further.
[0029] In a preferred embodiment, the locking assembly includes an adjusting rod 202 fixed to the outer wall of the support shaft 2. An L-shaped support block 203 is fixed to one side wall of the support frame 1 near the adjusting rod 202, and the adjusting rod 202 is located inside the support block 203. The support blocks 203 are configured as a pair, and a locking bolt 204 for fixing the adjusting rod 202 is provided inside the support block 203. The mounting bracket 201 is fixedly connected to one end of the support shaft 2 extending into the support frame 1. Loosening the locking bolt 204 and manually rotating the adjusting rod 202 causes the support shaft 2 to rotate, thereby causing the mounting bracket 201 and the clamped accessory to flip. Then, tightening the locking bolt 204 fixes the adjusting rod 202 inside the support block 203, thereby positioning the accessory. This allows for timely processing of the other side of the accessory, avoiding the hassle of disassembly and reinstallation.
[0030] In a preferred embodiment, the telescopic assembly includes a first electric push rod 3 fixedly through both sides of the mounting bracket 201, and a limiting clamp 301 fixedly connected to the telescopic end of the first electric push rod 3. When the refrigerator top frame accessory is placed in the mounting bracket 201, the first electric push rod 3 is activated. The telescopic end of the first electric push rod 3 drives the limiting clamp 301 to move towards the center, and the rubber block 302 contacts and clamps the accessory. The rubber block 302 avoids damage to the surface of the accessory. The anti-drop block 303 prevents the accessory from falling off during the flipping process, increasing the stability and reliability of the clamping, preventing the accessory from loosening or falling off during the flipping process, and ensuring the smooth progress of the painting operation. The telescopic movement of the first electric push rod 3 can adjust the distance between the limiting clamps 301, so that the equipment can adapt to the clamping requirements of refrigerator top frame accessories of different sizes, improving the versatility of the equipment.
[0031] In a preferred embodiment, the support assembly includes a first slide rail bracket 5 fixed to one side of the support frame 1. A support slide rail 501 is slidably connected inside the first slide rail bracket 5. A second slide rail bracket 503 is disposed inside the support slide rail 501. A slider 504 is slidably connected inside the second slide rail bracket 503. A second electric push rod 502 is fixed to the bottom inside the support slide rail 501. The second slide rail bracket 503 is fixedly connected to the telescopic end of the second electric push rod 502, and the second slide rail bracket 503 is slidably connected to the support slide rail 501. The gear assembly includes a third electric push rod 6 fixed to one side wall of the slider 504. The telescopic end of the third electric push rod 6 is fixed with a lifting block 601, and the lower end of the lifting block 601 is fixed with a gear rod 602. The side wall of the slider 504 is provided with a groove 603 for sliding one end of the lifting block 601. The connecting shaft 506 passes through the interior of the slider 504 and is rotatably connected. The end of the connecting shaft 506 near the gear rod 602 is provided with a toothed block 507, and the toothed block 507 is meshed with the gear rod 602. When the second electric push rod 502 is activated, the telescopic end of the second electric push rod 502 drives the second slide rail bracket 503 to slide up and down in the support slide rail 501, thereby adjusting the height of the slider 504 and the paint shell 505.
[0032] The first slide rail bracket 5 and the second slide rail bracket 503 are equipped with screws for driving, which drive the support slide rail 501 and the slider 504 to adjust their positions. This is existing technology and will not be described in detail.
[0033] When the third electric push rod 6 is activated, its telescopic end drives the lifting block 601 to slide up and down within the slide groove 603. The lifting block 601 drives the gear rod 602 to move up and down. Since the gear rod 602 meshes with the toothed block 507 on the connecting shaft 506, the up and down movement of the gear rod 602 drives the connecting shaft 506 to rotate, thereby causing the paint spraying shell 505 to be finely adjusted in angle, making it more accurately aligned with the surface of the accessory, and better spraying the upper side wall of the accessory. This achieves flexible adjustment of the paint spraying shell 505 in height, horizontal position, and angle, which can meet the painting needs of accessories of different shapes and positions, and allows the spray gun to accurately align with various parts of the accessory. It is especially suitable for the complex-shaped refrigerator top frame, improving the uniformity and quality of the spraying, and improving the accuracy and quality of the paint spraying.
[0034] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0035] During operation, the refrigerator top frame accessory is placed in the mounting bracket 201. The first electric push rod 3 is activated, and its telescopic end drives the limiting clamp 301 to move towards the center. The rubber block 302 contacts and clamps the accessory, and the anti-drop block 303 prevents the accessory from falling off during the flipping process. Then, the locking bolt 204 is loosened, and the adjusting rod 202 is manually rotated. The adjusting rod 202 drives the support shaft 2 to rotate, so that the mounting bracket 201 and the clamped accessory are flipped to a suitable angle. Then, the locking bolt 204 is tightened to fix the adjusting rod 202 in the support block 203. The second electric push rod 502 is activated, and its telescopic end drives the second slide rail bracket 503 to slide up and down in the support slide rail 501 to adjust the height of the slider 504 and the painted shell 505.
[0036] Simultaneously, the screws inside the first slide rail bracket 5 and the second slide rail bracket 503 drive the support slide rail 501 and slider 504 to adjust their horizontal positions. When the third electric push rod 6 is activated, its telescopic end drives the lifting block 601 to slide up and down in the slide groove 603. The lifting block 601 drives the gear rod 602 to move up and down. Since the gear rod 602 meshes with the tooth block 507 on the connecting shaft 506, it drives the connecting shaft 506 to rotate, causing the paint spraying housing 505 to make a fine angle adjustment and accurately align with the surface of the accessory for painting. During or after the painting process, the hot air unit 4 (model AFC series) is activated, and the generated hot air is guided to the surface of the accessory through the air guide housing 401. The hot air units 4 on both sides and the air guide housing 401 achieve simultaneous drying of both sides of the accessory, accelerating the drying speed of the paint.
