Description

Technical Field

[0001] This utility model relates to the field of aluminum profile processing technology, and in particular to a vertical powder spraying device for aluminum profile spraying. Background Technology

[0002] Aluminum profiles are alloy materials with aluminum as the main component. Aluminum rods are melted and extruded to obtain aluminum materials with different cross-sectional shapes. However, the mechanical properties and application fields of the produced aluminum profiles are different depending on the proportion of alloys added.

[0003] In the production process of aluminum profiles, different functional coatings are sprayed onto the aluminum profiles to improve their performance. For example, Chinese Patent CN21407741U discloses an automatic loading and unloading aluminum profile powder coating booth. This powder coating booth, with its air blowing plate and cleaning brush, facilitates the removal of dust clumps on the surface of the aluminum profiles entering the powder booth, thus preventing the dust on the surface of the aluminum profiles from affecting the coating quality. However, the dust brushed off by the cleaning brush is easily dispersed in the powder booth after being blown away by the air blowing plate and then easily re-adheres on the aluminum profiles, affecting the coating effect. Therefore, we propose a vertical powder coating device for aluminum profiles. Utility Model Content

[0004] The purpose of this invention is to provide a vertical powder coating device for aluminum profiles, which has a good dust removal effect and thus improves the coating effect.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a vertical powder coating device for aluminum profiles, comprising a spray booth, an inlet and an outlet opened on the spray booth, a support rod installed on the spray booth, a hanger installed on the support rod and passing through the inlet and outlet, a conveying assembly installed on the hanger, a driving assembly installed in the spray booth and driving the conveying assembly to move, and a spray gun and a hot air blower installed on the spray booth. Two connecting frames are installed at the inlet of the spray booth, a fan connected to the connecting frames is installed on the spray booth, and a dust removal assembly and an adsorption assembly engaging with the dust removal assembly are installed on the connecting frames.

[0006] By adopting the above technical solution, the aluminum profiles to be sprayed are hung on the conveying assembly. The drive assembly is started to move the conveying assembly, so that the aluminum profiles on the conveying assembly are sent one by one from the feed port into the spray booth. After the dust removal assembly removes the dust on the surface of the aluminum profiles, they are sprayed by the spray gun. After spraying, the aluminum profiles are dried by the hot air blower. Part of the dust removed by the dust removal assembly is adsorbed by the blower and the other part is adsorbed by the adsorption assembly, which reduces the spread of dust in the spray booth, improves the dust removal effect, and enhances the spraying effect of the aluminum profiles.

[0007] A further feature of this invention is that the conveying assembly includes multiple sliders slidably mounted on the hanger, a chain connecting the multiple sliders, and a hanging ring mounted on the bottom of the sliders.

[0008] By adopting the above technical solution, the aluminum profiles to be sprayed are hung one by one on the hanging rings. The drive component is started to drive the chain to rotate, and the aluminum profiles hanging on the hanging rings are sent one by one from the feed port to the spray booth for spraying.

[0009] A further feature of this invention is that the connection between the slider and the hanger is designed to be smooth.

[0010] By adopting the above technical solutions, the smooth design can reduce the resistance when the slider moves, making the aluminum profile transport smoother.

[0011] A further feature of this invention is that the drive assembly includes a drive motor mounted on the paint booth and a gear fixedly connected to the output shaft of the drive motor.

[0012] A further feature of this invention is that the gear engages with the chain.

[0013] By adopting the above technical solution, the drive motor starts and drives gear one to rotate. Gear one meshes with the chain and pushes the chain to move as a whole, thereby driving the hanging ring on the slider to move. The aluminum profiles hanging on the hanging ring are sent one by one from the feed port to the spray booth for spraying.

[0014] A further feature of this invention is that the dust removal assembly includes a rotating shaft rotatably connected to the inner side of the connecting frame, a brush roller and a sector gear mounted on the outside of the rotating shaft, and a rotating motor mounted on the connecting frame to drive the rotating shaft to rotate.

[0015] A further feature of this invention is that the outer surface of the brush roller is provided with a plurality of equally spaced bristles.

[0016] By adopting the above technical solution, the rotating motor starts and drives the brush roller outside the rotating shaft to rotate. When the brush roller rotates, it drives the brush bristles to rotate, cleaning the dust attached to the surface of the aluminum profile. Then, the fan starts to absorb the cleaned dust, preventing the cleaned dust from spreading in the paint booth, thus improving the dust removal effect and improving the painting effect of the aluminum profile.

[0017] A further feature of this invention is that the adsorption assembly includes two driven shafts rotatably connected to the inner side of the connecting frame, an adsorption roller installed between the two driven shafts, and a second gear installed outside one of the driven shafts and meshing with a sector gear.

[0018] By adopting the above technical solution, dust swept off the brush bristles will also adhere to the surface of the brush bristles. The adsorption roller will clean the dust adhering to the brush bristles. At the same time, the sector gear and the brush roller rotate synchronously. Since the sector gear meshes with the second gear, after the brush roller rotates once, the second gear drives the adsorption roller outside the driven shaft to rotate a certain distance. This allows the dust on the brush bristles to be evenly adsorbed on the surface of the adsorption roller, improving the adsorption effect of dust on the brush bristles, reducing the spread of dust in the paint booth, and improving the dust removal effect and the coating effect of aluminum profiles.

[0019] A further feature of this invention is that the length of the bristles is greater than or equal to the distance from the adsorption roller to the brush roller.

[0020] By adopting the above technical solution, the dust adhering to the brush bristles can be adsorbed by the adsorption roller.

[0021] A further feature of this invention is that the external surface of the adsorption roller is wrapped with adhesive paper, and the adsorption roller is detachably connected between the two driven shafts by bolts.

[0022] By adopting the above technical solution, it is convenient to replace the adsorption roller after a long period of adsorption.

[0023] The beneficial effects of this utility model are:

[0024] 1. The rotating motor starts and drives the brush roller outside the rotating shaft to rotate. When the brush roller rotates, it drives the brush bristles to rotate, cleaning the dust attached to the surface of the aluminum profile. Then the fan starts to absorb the cleaned dust, preventing the cleaned dust from spreading in the paint booth, thus improving the dust removal effect and improving the painting effect of the aluminum profile.

[0025] 2. Dust swept off the brush bristles will also adhere to the surface of the brush bristles. The adsorption roller is used to clean the dust adhering to the brush bristles, which improves the adsorption effect of dust on the brush bristles, reduces the spread of dust in the paint booth, and improves the dust removal effect, thus improving the coating effect of aluminum profiles.

[0026] 3. The sector gear rotates synchronously with the brush roller. Because the sector gear meshes with gear two, after the brush roller rotates one revolution, gear two drives the adsorption roller outside the driven shaft to rotate a certain distance, so that the dust on the brush bristles can be evenly adsorbed on the surface of the adsorption roller, further improving the adsorption effect of dust on the brush bristles, reducing the spread of dust in the paint booth, and improving the dust removal effect and the coating effect of aluminum profiles.

[0033] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] Please see Figure 1-4This utility model provides a vertical powder coating device for aluminum profiles, including a spray booth 1, an inlet 2 and an outlet 3 opened on the spray booth 1, a support rod 4 installed on the spray booth 1, a hanger 5 installed on the support rod 4 and passing through the inlet 2 and the outlet 3, a conveying assembly 6 installed on the hanger 5, a driving assembly 7 installed in the spray booth 1 and driving the conveying assembly 6 to move, and a spray gun 8 and a hot air blower 9 installed on the spray booth 1. Two connecting frames 10 are installed at the inlet 2 of the spray booth 1. A fan 11 connected to the connecting frames 10 is installed on the spray booth 1. A dust removal assembly 12 and an adsorption assembly 13 engaged with the dust removal assembly 12 are installed on the connecting frames 10.

[0035] The aluminum profiles to be sprayed are hung on the conveying assembly 6. The drive assembly 7 is started to move the conveying assembly 6, so that the aluminum profiles on the conveying assembly 6 are sent one by one from the feed port 2 into the spray booth 1. After the dust is removed from the surface of the aluminum profiles by the dust removal assembly 12, they are sprayed by the spray gun 8. After spraying, the aluminum profiles are dried by the hot air blower 11. Part of the dust removed by the dust removal assembly 12 is adsorbed by the blower 11 and the other part is adsorbed by the adsorption assembly 13, which reduces the spread of dust in the spray booth 1, improves the dust removal effect, and improves the spraying effect of the aluminum profiles.

[0036] The conveying assembly 6 includes multiple sliders 61 slidably mounted on the hanger 5, a chain 62 connecting the multiple sliders 61, and hanging rings 63 mounted on the bottom of the sliders 61. The aluminum profiles to be sprayed are hung one by one on the hanging rings 63. The drive assembly 7 is started to drive the chain 62 to rotate, and the aluminum profiles hanging on the hanging rings 63 are sent one by one from the feed port 2 to the spray booth 1 for spraying.

[0037] The connection between the slider 61 and the hanger 5 is designed to be smooth. This smooth design can reduce the resistance when the slider 61 moves, making the aluminum profile transported more smoothly.

[0038] The drive assembly 7 includes a drive motor 71 mounted on the spray booth 1 and a gear 72 fixedly connected to the output shaft of the drive motor 71. The gear 72 meshes with the chain 62. When the drive motor 71 starts, it drives the gear 72 to rotate. The gear 72 meshes with the chain 62 and pushes the chain 62 to move as a whole, thereby moving the hanging ring 63 on the slider 61. The aluminum profiles hanging on the hanging ring 63 are fed one by one from the feed port 2 into the spray booth 1 for spraying.

[0039] The dust removal assembly 12 includes a rotating shaft 121 rotatably connected to the inner side of the connecting frame 10, a brush roller 122 and a sector gear 123 installed on the outside of the rotating shaft 121, and a rotating motor 124 installed on the connecting frame 10 to drive the rotating shaft 121 to rotate. The brush roller 122 has a plurality of equally spaced bristles 125 on its outside. When the rotating motor 124 starts, it drives the brush roller 122 outside the rotating shaft 121 to rotate. When the brush roller 122 rotates, it drives the bristles 125 to rotate, cleaning the dust attached to the surface of the aluminum profile. Then the fan 11 starts to adsorb the cleaned dust, preventing the cleaned dust from spreading in the paint booth 1, thus improving the dust removal effect and the painting effect of the aluminum profile.

[0040] The adsorption assembly 13 includes two driven shafts 131 rotatably connected to the inner side of the connecting frame 10, an adsorption roller 132 installed between the two driven shafts 131, and a gear 133 installed outside one of the driven shafts 131 and meshing with the sector gear 123. Dust swept by the brush bristles 125 will also adhere to the surface of the brush bristles 125. The adsorption roller 132 is used to clean the dust attached to the brush bristles 125. At the same time, the sector gear 123 and the brush roller 122 rotate synchronously. Since the sector gear 123 meshes with the gear 133, when the brush roller 122 rotates one revolution, the gear 133 drives the adsorption roller 132 outside the driven shaft 131 to rotate a certain distance, so that the dust on the brush bristles 125 can be evenly adsorbed on the surface of the adsorption roller 132, improving the adsorption effect of the dust on the brush bristles 125, reducing the spread of dust in the paint booth 1, improving the dust removal effect, and improving the painting effect of the aluminum profile.

[0041] The length of the bristles 125 is greater than or equal to the distance between the adsorption roller 132 and the brush roller 122, so that the dust attached to the bristles 125 can be adsorbed by the adsorption roller 132.

[0042] The adsorption roller 132 is wrapped with adhesive paper and is detachably connected between the two driven shafts 131 by bolts, which facilitates the replacement of the adsorption roller 132 after long-term adsorption.
