Applying a thin coating to the surface of the metal product can protect the product from oxidation and corrosion, enhance its appearance and texture, and improve its durability and added value. It is widely used in many fields such as home appliances, automobiles, and construction.

[0003] When spraying a batch of hardware products, the hardware products need to be conveyed and placed at the air spray gun for surface spraying. After one hardware product is sprayed, it is necessary to replace it with an unsprayed hardware product and spray it again. This process is repeated to complete the surface spraying of a batch of hardware products.

[0004] However, it is cumbersome to replace different hardware products one by one to complete the spraying. It is also impossible to continuously spray a batch of hardware products. Replacing hardware products is time-consuming, resulting in low spraying efficiency of hardware products. Therefore, a surface spraying device for hardware products is proposed to address the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 As shown, the surface spraying device for hardware products includes a support platform 1, a spraying chamber 11 installed on the top of the support platform 1, a conveying component 2 installed on the top of the inner wall of the spraying chamber 11 for conveying the hardware products to be sprayed, a spraying component 3 installed on the back of the inner wall of the spraying chamber 11, and a collecting component 4 provided at the bottom of the inner wall of the spraying chamber 11.

[0029] The conveying assembly 2 includes a hole one and a hole two opened in the top of the spraying chamber 11. A first electric telescopic rod 201 is installed on the top of the hole one. An installation cylinder 202 is slidably installed inside the hole two. The telescopic rod of the first electric telescopic rod 201 passes through the hole one and is fixedly installed with a connecting rod 203. A drive motor 204 is installed inside the installation cylinder 202. The output shaft of the drive motor 204 passes through the installation cylinder 202 and the connecting rod 203 and is installed with a rotating disk 205. A connecting column 206 is installed on the side of the rotating disk 205. A hook 207 is installed on the outer surface of the connecting column 206.

[0030] The mounting cylinder 202 is fixedly installed on the top of the connecting rod 203. Multiple hooks 207 are provided, and the multiple hooks 207 are located inside the rotating disk 205 and are distributed in a circumferential array.

[0031] Through the above technical solution, two holes, one through and the other through, are made in the top of the spraying chamber 11. The first electric telescopic rod 201 is installed at the top of the first hole, and the telescopic rod of the first electric telescopic rod 201 can extend into the interior of the spraying chamber 11 through the first hole to connect to the connecting rod 203. The connecting rod 203 is then installed on the top of the inner wall of the spraying chamber 11. The mounting cylinder 202 can be movably installed inside the second hole, and the bottom of the mounting cylinder 202 can be fixedly installed on the top of the connecting rod 203. The drive motor 204 is installed in a fixed position inside the mounting cylinder 202, and the output shaft of the drive motor 204 can pass through the mounting cylinder 202 and the connecting rod 203 to connect to the rotating disk 205. The outer surface of the rotating disk 205 has multiple holes, so that multiple connecting posts 206 can be installed into the multiple holes respectively. A hook 207 is sleeved on the outer surface of each connecting post 206, so that hardware parts can be hung on the hook 207. When spraying the surface of hardware parts, the worker hangs the hardware parts on the hook 207, powers on the drive motor 204 to start it, and drives the rotating disk 205 to rotate slowly. This causes the hardware parts hanging on the hook 207 to rotate to the spraying component 3. The spraying component 3 can then spray the surface of the hardware parts. After the hardware parts are sprayed, they rotate once and return to the front of the spraying chamber 11. The worker can then remove the hardware parts and re-hang the hardware parts to be sprayed. The hardware parts are then transported to the spraying component 3 for spraying, achieving the effect of continuous spraying of batches of hardware parts. When the hardware parts have different specifications, the first electric telescopic rod 201 can be activated to drive the connecting rod 203 and the mounting cylinder 202 to move up and down, so that the drive motor 204 and the rotating disk 205 can move up and down together. The distance between the bottom hook 207 of the rotating disk 205 and the bottom of the inner wall of the spraying chamber 11 can be adjusted to hang and spray hardware parts of different specifications.

[0032] It should be noted that a control box is installed on the outer wall of the spray booth 11. The control box contains a control switch, which is electrically connected to the drive motor 204, the first electric telescopic rod 201, and the second electric telescopic rod 305. The program can send signals to the control switch in the control box to power on and stop the drive motor 204, the first electric telescopic rod 201, and the second electric telescopic rod 305. There are two first electric telescopic rods 201, which are symmetrically distributed on the left and right sides of the mounting cylinder 202. The two first electric telescopic rods 201 can be started synchronously through the control box to stably raise and lower the connecting rod 203.

[0033] Considering the issue of how to apply paint to the surface of hardware parts, the following is provided: Figure 1 and Figure 4 The specific structure of the spraying assembly 3 is disclosed. The spraying assembly 3 includes a slide 301 opened on the back of the spraying chamber 11. An air spray gun body 302 is slidably installed inside the slide 301. The nozzle of the air spray gun body 302 extends into the interior of the spraying chamber 11 and is sleeved with a sliding plate 303. The part of the air spray gun body 302 located outside the spraying chamber 11 is sleeved with a connecting sleeve 304. A second electric telescopic rod 305 is installed on the bottom of the outer surface of the connecting sleeve 304.

[0034] The bottom of the second electric telescopic rod 305 is equipped with a fixing block 5. The second electric telescopic rod 305 is located on the back of the spray booth 11, and the fixing block 5 is fixedly installed on the back of the support platform 1.

[0035] Through the above technical solution, a slide rail 301 is opened on the back of the spray chamber 11, and a sliding plate 303 is installed on the back of the inner wall of the spray chamber 11. The nozzle of the air spray gun body 302 is inserted into the slide rail 301 and passes through the sliding plate 303, so that the telescopic rod of the second electric telescopic rod 305 is connected to the bottom of the outer surface of the air spray gun body 302 through the connecting sleeve 304. The bottom of the second electric telescopic rod 305 is installed on the top of the fixing plate to fix the second electric telescopic rod 305. When the second electric telescopic rod 305 is powered on, it can drive the air spray gun body 302 in the slide rail. The air spray gun body 302 moves up and down inside 301, and when it moves, it will drive the sliding plate 303 to move up and down together, adjusting the air spray gun body 302 to different height positions. When the hardware part is rotated to the nozzle of the air spray gun body 302 by the rotating disk 205, the air spray gun body 302 works to spray out a mist of paint to coat the surface of the hardware part. The first electric telescopic rod 201 is powered on and drives the air spray gun body 302 to move up and down, adjusting the air spray gun body 302 to different positions, and completely coating the surface of the hardware part with paint.

[0036] It should be noted that when the air spray gun body 302 moves up and down inside the slide 301, it will drive the sliding plate 303 to move up and down together. The sliding plate 303 is located outside the slide 301 and can block the gaps in the slide 301 to prevent the sprayed paint from overflowing the spray chamber 11 through the sliding gaps. The tail of the air spray gun body 302 is connected to the paint tank and the air compressor through pipes. The compressed air provided by the air compressor enters the air channel of the spray gun through the pipes. The compressed air is sprayed out from the air cap and forms a negative pressure at the front end of the paint nozzle, which draws the paint from the paint tank and atomizes it into fine droplets. The droplets are then sprayed onto the surface of the hardware product with the airflow to form a uniform coating.

[0037] Secondly, considering the issue of how to collect and dispose of the excess paint sprayed out, please provide... Figure 1 and Figure 5 The specific structure of the collection component 4 is disclosed. The collection component 4 includes a collection tank 401 located at the bottom of the inner wall of the spray chamber 11. A liquid outlet tank 402 is provided at the bottom of the inner wall of the collection tank 401. A filter screen 403 is installed inside the liquid outlet tank 402. A liquid outlet 404 is provided at the bottom of the inner wall of the liquid outlet tank 402.

[0038] The collection tank 401 is located below the air spray gun body 302, and a partition 6 is installed on the top of the inner wall of the spray chamber 11. The partition 6 is located below the rotating disk 205.

[0039] Through the above technical solution, a semi-circular collection trough 401 is opened at the bottom of the inner wall of the spraying chamber 11. An arc-shaped liquid outlet trough 402 is opened on the bottom side of the inner wall of the collection trough 401. A liquid outlet 404 is opened at the bottom of the liquid outlet trough 402. A filter screen 403 is installed on the top of the inner wall of the liquid outlet 402. A vertically placed partition 6 is installed at the bottom of the inner wall of the spraying chamber 11. When the spraying assembly 3 sprays the hardware parts, the excess paint sprayed by the air spray gun body 302 will be blocked by the partition 6, and the scattered paint will enter the interior of the collection trough 401. After being filtered by the filter screen 403, it will flow out from the liquid outlet 404 at the bottom of the liquid outlet trough 402, thus achieving the effect of collecting and treating excess paint.

[0040] In summary, the working principle of this utility model is as follows:

[0041] When spraying the surface of hardware parts, the worker hangs the hardware parts on the hook 207, powers on the drive motor 204 to start it, and drives the rotating disk 205 to rotate slowly. This drives the hardware parts hanging on the hook 207 to the spraying component 3, where the spraying component 3 can spray the surface of the hardware parts. After the hardware parts are sprayed, they rotate once and return to the front of the spraying chamber 11. The worker can then remove the hardware parts and hang them on again to continue transporting them to the spraying component 3 for spraying. This achieves the effect of continuous spraying of batches of hardware parts. When the hardware parts have different specifications, the first electric telescopic rod 201 can be activated to drive the connecting rod 203 and the mounting cylinder 202 to move up and down, so that the drive motor 204 and the rotating disk 205 can move up and down together. The distance between the bottom hook 207 of the rotating disk 205 and the bottom of the inner wall of the spraying chamber 11 can be adjusted to hang and spray hardware parts of different specifications.

[0042] When the hardware parts are rotated by the rotating disk 205 to the nozzle of the air spray gun body 302 for spraying, the air spray gun body 302 sprays out a mist of paint to coat the surface of the hardware parts. The first electric telescopic rod 201 is powered on and drives the air spray gun body 302 to move up and down, adjusting the air spray gun body 302 to different positions to completely coat the surface of the hardware parts with paint. Excess paint sprayed by the air spray gun body 302 is blocked by the partition 6, and the scattered paint enters the inside of the collection tank 401. After being filtered by the filter screen 403, it flows out from the liquid outlet 404 at the bottom of the liquid outlet tank 402, achieving the effect of collecting and treating excess paint.
