DETAILED DESCRIPTION

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] With reference to Figures 1-3 , the present application provides an embodiment:

[0030] An environment-friendly aluminum alloy powder spraying device, comprising a device housing 1, a powder spraying mechanism 8 and a clamping mechanism 9, a fixed plate 2 is fixedly arranged at one end of the outer side of the device housing 1, a powder suction pump 7 is fixedly arranged at the lower end of the fixed plate 2, a powder storage tank 3 is fixedly arranged at the upper end of the fixed plate 2, a collection tank 4 is fixedly arranged at one side of the inner bottom end of the device housing 1, a connecting pipe 6 is fixedly arranged at one side of the collection tank 4, a placement plate 10 is fixedly arranged at the upper end of one side of the inner end of the device housing 1, a No. 1 motor 12 is fixedly arranged at one side of the lower end of the placement plate 10, a No. 1 gear 13 is fixedly arranged at the output end of the No. 1 motor 12, a dryer 11 is fixedly arranged at the upper end of the placement plate 10, a No. 1 telescopic pipe 14 is fixedly arranged at the output end of the dryer 11, a hot air distribution box 15 is fixedly arranged at the other side of the No. 1 telescopic pipe 14, a rack 16 is fixedly arranged at the lower end of the rear end of the hot air distribution box 15, the No. 1 gear 13 is meshingly connected with the rack 16, an inclined plate 5 is fixedly arranged at the lower end of the other side of the inner end of the device housing 1, the input end of the powder suction pump 7 is fixedly connected with the lower end of the powder storage tank 3, and the collection tank 4 is fixedly arranged at the lower end of the inclined plate 5.

[0031] Specifically, the powder spraying mechanism 8 of the present application can adjust the spraying angle of the powder coating sprayed from the powder storage tank 3, and the clamping mechanism 9 can firmly clamp the aluminum alloy.

[0032] With reference to Figure 4 , Figure 5The powder spraying mechanism 8 comprises two mounting plates 801, a powder outlet box 803 and a second motor 804. The powder outlet box 803 is fixedly provided with rotating columns 802 on two sides. One outer end of one of the rotating columns 802 is fixedly provided with a second gear 806. A first telescopic rod 807 is fixedly provided at a lower end of one side of the powder outlet box 803. An electrostatic friction plate 808 is fixedly provided at the other side of the first telescopic rod 807. A first spring 809 is provided at a rear end of the electrostatic friction plate 808. A second telescopic pipe 810 is fixedly provided at the other side of the powder outlet box 803. A third gear 805 is fixedly provided at an output end of the second motor 804. The second telescopic pipe 810 is fixedly connected with an output end of the powder storage box 3. The second motor 804 is fixedly connected with one of the two mounting plates 801. The two rotating columns 802 are rotatably connected with the two mounting plates 801 respectively. The second gear 806 is meshingly connected with the third gear 805. The powder outlet box 803 is rotatably arranged at one side of an inner end of the device housing 1.

[0033] Specifically, after the second motor 804 is started, the angle of the powder outlet box 803 can be changed due to the meshing of the second gear 806 and the third gear 805. The electrostatic friction plate 808 increases static electricity on the clamped aluminum alloy surface, so that when the powder outlet box 803 moves downward, the electrostatic friction plate 808 can cover the entire aluminum alloy to be sprayed. The powder coating not attached to the aluminum alloy surface can enter the collection box 4 along the inclined plate 5. After the powder suction pump 7 is started, the unattached powder coating can be re-sucked into the powder storage box 3. The electrostatic friction plate 808 can ensure uniform attachment of the powder coating, thereby improving the consistency and quality of the coating. The unattached powder coating can be effectively collected into the collection box 4 through the inclined plate 5, which can reduce the waste of coating and reduce production cost. The adjustable angle of the powder outlet box 803 makes the powder spraying process more flexible and can adapt to aluminum alloy workpieces of different sizes.

[0034] Referring to Figure 6 , Figure 7 The clamping mechanism 9 comprises a second telescopic rod 901. An activity plate 902 is fixedly provided on the inner rod of the second telescopic rod 901. Two mounting grooves 903 are formed at the lower end of the activity plate 902. Guide columns 904 are fixedly provided at the inner ends of the two mounting grooves 903. Second springs 905 are provided at one side of the two mounting grooves 903. Clamping plates 906 are fixedly provided at opposite ends of the two second springs 905. The second telescopic rod 901 is fixedly provided at the top end of the device housing 1 on the other side. The two clamping plates 906 are movably provided at the lower end of the activity plate 902. The electrostatic friction plate 808 is movably provided at the other side of the two clamping plates 906. The drying machine 11 is provided at one side of the two clamping plates 906.

[0035] Specifically, when clamping the aluminum alloy, the second spring 905 at the rear end of the two clamping plates 906 pushes the clamping plates 906 to firmly clamp the aluminum alloy, ensuring that the workpiece does not loosen during the spraying process, improving the safety and reliability of the operation, and at the same time, the second telescopic rod 901 can adjust the position of the aluminum alloy. After the powder coating is sprayed on the surface of the aluminum alloy, starting the drying machine 11 can quickly dry the coating on the surface of the clamped aluminum alloy, speeding up the production efficiency and shortening the processing time of the product. In addition, after starting the first motor 12, the hot air distribution box 15 can change the air outlet position of the hot air distribution box 15 by rotating at the upper end of the placement plate 10, thereby optimizing the distribution effect of the hot air.

[0036] Working principle: after starting the second motor 804, the angle of the powder outlet box 803 can be changed because the second gear 806 is engaged with the third gear 805, and the electrostatic friction plate 808 increases static electricity on the surface of the clamped aluminum alloy, so that when the powder outlet box 803 moves downward, the electrostatic friction plate 808 can cover the entire aluminum alloy to be sprayed, and the powder coating not attached to the surface of the aluminum alloy will enter the collection box 4 along the inclined plate 5, and after starting the powder suction pump 7, it can be re-sucked into the powder storage box 3.

[0037] Secondly, when clamping the aluminum alloy, the second spring 905 at the rear end of the two clamping plates 906 pushes the clamping plates 906 to firmly clamp the aluminum alloy, ensuring that the workpiece does not loosen during the spraying process, improving the safety and reliability of the operation, and at the same time, the second telescopic rod 901 can adjust the position of the aluminum alloy. After the powder coating is sprayed on the surface of the aluminum alloy, starting the drying machine 11 can quickly dry the coating on the surface of the clamped aluminum alloy, and in addition, after starting the first motor 12, the hot air distribution box 15 can change the air outlet position of the hot air distribution box 15 by rotating at the upper end of the placement plate 10.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
