[0037] A vertical powder spraying system for aluminum profiles with online polishing function, comprising a transport track 1, a hanging assembly 2, a loading device 3, a polishing device 4, a pre-treatment device 5, a drying device 6, a powder spraying device 7, a curing device 8, and a unloading device 9;

[0038] The hanging component 2 is movably arranged on the transport track 1, and the hanging component 2 is used to hang and fix the aluminum profile workpiece 10 to be powder-sprayed. The transport track 1 passes through the loading device 3, the polishing device 4, the pre-treatment device 5, the drying device 6, the powder spraying device 7, the curing device 8 and the unloading device 9 in sequence; the loading device 3 is used to load the aluminum profile workpiece 10 to be powder-sprayed, the polishing device 4 is used to polish the aluminum profile workpiece 10 to be powder-sprayed, the pre-treatment device 5 is used to pre-treat the aluminum profile workpiece 10 to be powder-sprayed before powder spraying, the drying device 6 is used to dry the aluminum profile workpiece 10 to be powder-sprayed, the powder spraying device 7 is used to powder-spray the aluminum profile workpiece 10 to be powder-sprayed, the curing device 8 solidifies the aluminum profile workpiece 10 after powder spraying, and the unloading device 9 is used to unload the aluminum profile workpiece 10 after powder spraying.

[0039] This solution is a vertical powder spraying system for aluminum profiles with online polishing function, such as Figure 1-2 and Figure 4As shown, when the aluminum profile workpiece 10 needs to be powder-sprayed, the staff first hangs several aluminum profile workpieces 10 to be powder-sprayed on the loading device 3 on the hanging assembly 2. The hanging assembly 2 can fix the aluminum profile workpiece 10 to prevent the aluminum profile workpiece 10 from shaking during transportation. Since the hanging assembly 2 is movably arranged on the transport track 1, the aluminum profile workpiece 10 to be powder-sprayed is first transported to the polishing device 4 for polishing. Then, the polished aluminum profile workpiece 10 to be powder-sprayed is transported to the pre-treatment device 5 for pre-treatment before powder spraying, which provides a good foundation for subsequent powder spraying. Specifically, the pre-treatment before powder spraying includes operations such as degreasing, pickling and chromizing. Then, the aluminum profile workpiece 10 to be powder-sprayed after pre-treatment is transported to the drying device 6 for drying to ensure that the surface of the aluminum profile workpiece 10 is dry and to prevent coating quality problems caused by moisture or residual liquid. Next, the dried aluminum profile workpiece 10 to be powder-coated is transported to the powder spraying device 7 for powder coating. The powder-coated aluminum profile workpiece 10 is then transported to the curing device 8 for curing. In this embodiment, the curing process is specifically a heat-curing process. Through the heat-curing process, the powder coating is cured to form a film on the aluminum profile workpiece 10, forming a strong, aesthetically pleasing, and corrosion-resistant coating, thereby improving the service life and aesthetics of the aluminum profile workpiece 10. Finally, the cured, powder-coated aluminum profile workpiece 10 is transported to the unloading device 9 for manual unloading.

[0040] It is further explained that the loading device 3, the pre-treatment device 5, the drying device 6, the curing device 8 and the unloading device 9 are all existing technical structures and will not be described in detail here.

[0041] In this solution, by providing a polishing device 4 in front of the pre-treatment device 5, the aluminum profile workpiece 10 can be polished before the pre-treatment before powder spraying. The provision of the polishing device 4 not only improves the surface finish of the aluminum profile workpiece 10, but also removes surface defects of the aluminum profile workpiece 10, thereby improving the adhesion of the powder coating on the aluminum profile workpiece 10 during the subsequent powder spraying process, thereby improving the aesthetics and overall quality of the finished aluminum profile.

[0042] Preferably, the hanging assembly 2 includes a slider 21 and a hanger 22, wherein the slider 21 is slidably mounted on the transport track 1, and the hanger 22 is fixed to the slider 21. Figure 3-4 As shown, since the slider 21 is slidably mounted on the conveying track 1, the slider 21 is allowed to slide freely on the conveying track 1, thereby realizing automatic transportation of the aluminum profile workpiece 10. By providing the suspension bracket 23, the aluminum profile workpiece 10 can be stably suspended and fixed, avoiding possible shaking or displacement during transportation.

[0043] Preferably, the polishing device 4 includes a lifting bracket 41, a driving mechanism 42 and a plurality of pairs of polishing units 43, wherein the driving mechanism 42 includes a first driver 421 and a sprocket chain assembly 422;

[0044] The first driver 421 is arranged at the bottom of the lifting bracket 41, and the sprocket chain assembly 422 is arranged on the lifting bracket 41. The first driver 421 is used to drive the sprocket chain assembly 422 to operate. Each pair of the polishing units 43 is movably arranged on the lifting bracket 41 through the sprocket chain assembly 422. Several pairs of the polishing units 43 are evenly spaced along the up and down directions, and the two polishing units 43 in each pair of the polishing units 43 are symmetrically distributed on the left and right.

[0045] In this embodiment, Figure 2 and Figure 5 As shown, the first driver 421 is a motor, and three pairs of polishing units 43 are mounted on the lifting bracket 41. When the aluminum profile workpiece 10 is transported to the polishing device 4, it is positioned between each pair of polishing units 43, allowing each pair of polishing units 43 to polish both sides of the aluminum profile workpiece 10. Upon activation of the first driver 421, the first driver 421 drives the sprocket chain assembly 422. Since each pair of polishing units 43 is vertically movable on the lifting bracket 41 via the sprocket chain assembly 422, the operation of the sprocket chain assembly 422 drives each pair of polishing units 43 up and down, thereby adjusting the height of each pair of polishing units 43 and achieving polishing of the aluminum profile workpiece 10. Since the multiple pairs of polishing units 43 are evenly spaced vertically, each pair of polishing units 43 can simultaneously polish the aluminum profile workpiece 10 within its own varying height range, improving the polishing efficiency of the entire aluminum profile workpiece 10.

[0046] Preferably, the polishing unit 43 includes a support seat 431, and the sprocket chain assembly 422 includes two first sprockets 4221, two second sprockets 4222, two third sprockets 4223, two fourth sprockets 4224, two fifth sprockets 4225, two sixth sprockets 4226, two first chains 4227, two first rotating shafts 4228 and two second rotating shafts 4229;

[0049] The support base 431 is mounted on the lifting bracket 41 so as to be movable up and down. The support base 431 is connected to the two first chains 4227 .

[0050] In this embodiment, Figure 3 、 Figure 5-6As shown, when the polishing unit 43 needs to move up and down, the first driver 421 is activated, and the first driver 421 drives the fourth sprocket 4224 located at the rear side to rotate. The fourth sprocket 4224 located at the rear side drives the first chain 4227 connected thereto to transmit power, and the fourth sprocket 4224 located at the front side rotates, thereby driving the first chain 4227 connected to the fourth sprocket 4224 located at the front side to transmit power, thereby driving the two third sprockets 4223, the two second sprockets 4222, the two first sprockets 4221, the two sixth sprockets 4226, and the two fifth sprockets 4225 to rotate, thereby realizing the operation of the entire sprocket chain assembly 422. Since the support base 431 is mounted on the lifting bracket 41 so as to be movable up and down, the support base 431 is connected to the two first chains 4227. The transmission of the two first chains 4227 can drive the support base 431 to move up and down, thereby driving the entire polishing unit 43 to move up and down.

[0051] Preferably, the polishing unit 43 further includes a front-back translation assembly 432 , a left-right translation assembly 433 , a mounting seat 434 , a mounting frame 435 , a polishing roller 436 , and a second driver 437 ;

[0053] Specifically, if Figure 8As shown, the front-to-back translation assembly 432 enables the mounting frame 435 to move forward and backward, thereby achieving forward and backward movement of the polishing roller 436. The left-right translation assembly 433 enables the mounting frame 435 to move left-right, thereby achieving left-right movement of the polishing roller 436. Since the driving end of the second driver 437 is connected to one end of the polishing roller 436, by activating the second driver 437 (in this embodiment, the second driver 437 is a motor), the second driver 437 can drive the polishing roller 436 to rotate, thereby polishing the surface of the aluminum profile workpiece 10. The installation of the mounting base 434 ensures more stable installation of the left-to-right translation assembly 433. The mounting frame 435 provides support for the second driver 437 and the polishing roller 436. Furthermore, the polishing roller 5 can freely move in the front-to-back, left-to-right, and up-down directions. This multi-directional movement allows the polishing roller 436 to flexibly contact and polish various surfaces of the long aluminum profile 5 to be polished.
