[0025] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 8 The embodiments are described in detail below.

[0026] This embodiment provides a high-efficiency and environmentally friendly powder coating device for sheet metal processing, as shown in the attached figure. Figures 1-8 As shown, the device includes a base 1 and a support frame 2. The upper surface of the base 1 has a mesh 6 for collecting powder, and the lower surface of the base 1 has a storage box 7 for holding powder. The mesh 6 corresponds to the inside of the storage box 7. When spraying powder, the powder that is not adsorbed onto the sheet metal parts will fall onto the upper surface of the base 1. Some of the powder can fall directly from the mesh 6 into the storage box 7 below. After the powder spraying is finished, the remaining powder accumulated on the upper surface of the base 1 can be swept by the operator through the mesh 6 into the storage box 7 below by brushing. This allows for unified collection of powder, reduces waste, and prevents powder from spilling randomly.

[0027] The support frame 2 is externally fixedly equipped with a protective cover 8 and has a detachable front baffle 9 on the front. The front baffle 9 and the protective cover 8 can completely surround the support frame 2, thereby providing a certain degree of protection when the powder spraying mechanism sprays powder, preventing powder from scattering everywhere, and reducing the amount of powder inhaled by the operator. Magnetic blocks are fixedly installed on both sides of the front baffle 9. The front baffle 9 can be magnetically attracted to the front of the support frame 2 by the magnetic blocks, and can be easily removed to facilitate the placement of sheet metal parts into the support frame 2.

[0028] The support frame 2 is fixedly connected to the upper surface of the base 1, and the top end is provided with a first transverse moving mechanism. The first transverse moving mechanism comprises a first threaded lead screw 10, a gear shaft 11, a belt 12, a first driving motor 13 and a first screw block 14. The number of the first threaded lead screw 10 is two, and both of the first threaded lead screws 10 are rotatably connected to the two sides of the top of the support frame 2 through bearings. Both of the first threaded lead screws 10 are externally threadedly connected with the first screw block 14. Both of the first threaded lead screws 10 are fixedly connected with the gear shaft 11 at the same end, and the belt 12 is drivingly connected to the outside of the two gear shafts 11. The gear shaft 11 and the belt 12 are externally sleeved with a protective box 15, and the protective box 15 is fixedly connected to the top of the side of the support frame 2. The first driving motor 13 is fixedly installed on the side of the protective box 15, and the output shaft is arranged in the inside of the protective box 15 and connected with one of the gear shafts 11 through a spline. The first driving motor 13 drives one of the gear shafts 11 to rotate, which can drive the other gear shaft 11 to synchronously rotate through the belt 12, so that the two first threaded lead screws 10 synchronously rotate. The two first screw blocks 14 are fixedly connected with a limiting rod on the top of the side close to each other, which plays a role in connecting the two first screw blocks 14 and limiting the second screw block 18. Under the action of the limiting rod, the two first screw blocks 14 can move horizontally transversely under the drive of the first threaded lead screw 10, thereby driving the second transverse moving mechanism and the overall structure below to move transversely.

[0029] The movable end of the first transverse moving mechanism is provided with a second transverse moving mechanism. The second transverse moving mechanism comprises a second driving motor 16, a second threaded lead screw 17 and a second screw block 18. The second driving motor 16 is fixedly installed on the side of one of the first screw blocks 14, and the output shaft is connected with the second threaded lead screw 17 through a spline. The second threaded lead screw 17 is rotatably connected between the two first screw blocks 14. The second screw block 18 is threadedly connected to the outside of the second threaded lead screw 17. The second screw block 18 is sleeved on the outside of the limiting rod and can slide transversely along the outside. The second driving motor 16 drives the second threaded lead screw 17 to rotate, which can drive the second screw block 18 to move transversely through the thread. The moving direction of the second screw block 18 is perpendicular to the moving direction of the first screw block 14. Under the cooperation of the first transverse moving mechanism and the second transverse moving mechanism, the nozzle mechanism below can move arbitrarily in the same horizontal direction in the support frame 2.

[0030] The middle part of the second transverse moving mechanism is provided with a lifting mechanism, which comprises a mounting plate 19 and an electric lifting rod 20. The mounting plate 19 is fixedly connected to the bottom end of the second screw sliding block 18. The electric lifting rod 20 is fixedly installed on the upper surface of the mounting plate 19. The movable end of the electric lifting rod 20 is arranged in the lower surface of the mounting plate 19 and is fixedly connected to the circular plate 3. The electric lifting rod 20 can control the lifting of the overall structure at the bottom, so as to adjust the height of the nozzle mechanism. After being used in cooperation with the first transverse moving mechanism and the second transverse moving mechanism, the nozzle mechanism can be randomly moved in the three-dimensional space of the supporting frame 2, so as to facilitate the powder spraying treatment of any part around the sheet metal part.

[0031] The bottom of the movable end of the lifting mechanism is fixedly connected to the circular plate 3, and the upper surface of the circular plate 3 is fixedly installed with a rotating rudder 4. The output end of the rotating rudder 4 is connected with a rotating plate 5 through a spline. The rotating rudder 4 can drive the rotating plate 5 to rotate, so as to rotate the telescopic mechanism and the nozzle mechanism below. According to the situation, the nozzle mechanism can make uniform circular motion around the sheet metal part, so as to spray powder around the sheet metal part.

[0032] The surface of the rotating plate 5 is provided with a telescopic mechanism, which comprises an electric telescopic rod 21 and a fixed frame 22. The lower surface of the circular plate 3 is fixedly connected with a sleeve ring 23 for fixing the fixed rod body part of the electric telescopic rod 21. The fixed rod body of the electric telescopic rod 21 is fixedly connected to the inside of the sleeve ring 23, and the number of the electric telescopic rod 21 is two. The two electric telescopic rods 21 are symmetrically arranged with the vertical center line of the circular plate 3 as the axis of symmetry. The fixed frame 22 is fixedly connected to the movable rod body end of the two electric telescopic rods 21. The electric telescopic rod 21 can adjust the distance between the fixed frame 22 and the structure below and the center of the rotating plate 5, so as to adjust the rotating radius of the nozzle mechanism, which is suitable for rotating and spraying powder on sheet metal parts of different sizes.

[0033] The movable end of the telescopic mechanism is provided with an adjustable angle adjusting mechanism. The angle adjusting mechanism comprises a speed reducer 24, a straight gear rod 25 and an adjusting plate 26. The straight gear rod 25 is connected to the output shaft of the speed reducer 24 through a spline, and the speed reducer 24 is fixedly installed on the side surface of the fixed frame 22. The top end of the adjusting plate 26 is provided with a gear tooth engaged with the straight gear rod 25. The top end of the adjusting plate 26 is hingedly connected to the bottom of the inner side wall of the fixed frame 22, and the top end is engaged with the straight gear rod 25 through the gear tooth. When the speed reducer 24 drives the straight gear rod 25 to rotate clockwise, the straight gear rod 25 can drive the adjusting plate 26 to rotate counterclockwise through the gear tooth, so as to make the nozzle mechanism face obliquely upward. When the speed reducer 24 drives the straight gear rod 25 to rotate counterclockwise, the adjusting plate 26 can be driven to rotate clockwise through the gear tooth, so as to make the nozzle mechanism face obliquely downward.

[0034] The side of the angle adjusting mechanism is provided with a spray head mechanism for powder spraying, which comprises a plurality of spray head fixing frames 27, a plurality of powder spraying heads 28 and a plurality of distance sensors 29. The spray head fixing frames 27 are equidistantly fixedly connected to one side of the adjusting plate 26 close to the electric telescopic rod 21, and each spray head fixing frame 27 is fixedly installed with a plurality of equidistantly horizontally arranged powder spraying heads 28 on the side thereof. The powder spraying heads 28 are communicated with external powder spraying equipment through pipelines, and the powder is sprayed out from the powder spraying heads 28 through the external powder spraying equipment. The distance sensors 29 are fixedly installed on the side of the spray head fixing frame 27 close to the electric telescopic rod 21, and the corresponding directions of the distance sensors 29 are consistent with the directions of the powder spraying heads 28. The distance sensors 29 can monitor the distance between the distance sensors 29 and the surface of the corresponding sheet metal part in real time. When the distance changes, the telescopic mechanism can be controlled to move by the control unit, so that the distance between the powder spraying heads 28 and the corresponding sheet metal part is always consistent. In addition, the distance sensors 29 are provided in multiple groups and have different heights. The distances between the distance sensors 29 and the sheet metal part are monitored in real time by the distance sensors 29 with different heights. When the distances monitored by the distance sensors 29 at the top and bottom are different from the distances monitored by the distance sensors 29 in other groups, it is proved that the part corresponding to the distance sensor 29 with the change on the sheet metal part is bent. At this time, the powder spraying head 28 corresponding to the part can be controlled to stop spraying powder. The control unit adjusts the powder spraying head 28 to the part with the same distance as the bent part by the first horizontal moving mechanism, the second horizontal moving mechanism, the lifting mechanism and the angle adjusting mechanism, and then sprays powder on the bent part of the sheet metal part. The powder spraying head 28 can always maintain the same distance with each surface of the sheet metal part, so that the powder spraying state remains the same, thereby making the powder spraying more uniform and consistent, and improving the processing quality of the sheet metal part.

[0035] The rudder 4, the first driving motor 13, the second driving motor 16, the electric lifting rod 20, the electric telescopic rod 21, the speed reducer 24 and the distance sensor 29 are electrically connected with the external control unit and are electrically connected with the external circuit through wires.

[0036] In summary, the efficient and environmentally friendly powder spraying device for sheet metal processing has the following use steps:

[0037] 1. First, remove the front baffle 9, place the sheet metal part to be sprayed on the middle part of the upper surface of the base 1, and then cover the front baffle 9 on the front surface of the support frame 2. The powder spraying head mechanism is adjusted to the part to be sprayed on the sheet metal part by cooperation of the first horizontal moving mechanism, the second horizontal moving mechanism, the lifting mechanism and the telescopic mechanism.

[0038] 2. The sheet metal part is sprayed by the external powder spraying equipment, and the powder spraying head mechanism is moved at a constant speed by cooperation of the first horizontal moving mechanism, the second horizontal moving mechanism and the lifting mechanism, so that the surface of the sheet metal part is uniformly sprayed.

[0039] 3. Through real-time monitoring of multiple sets of distance sensors 29, the specific structure of the sheet metal part can be accurately known, and through adjustment of the first transverse moving mechanism, the second transverse moving mechanism, the lifting mechanism, the telescopic mechanism and the angle adjusting mechanism, the powder spraying head 28 can always maintain the same distance with the corresponding surface when spraying powder on different parts around the sheet metal part, so that the powder spraying head 28 can uniformly spray powder on any part around the sheet metal part.

[0040] The above is only for the purpose of illustrating the present application, and it should be understood that the present application is not limited to the above embodiments, and various modifications in accordance with the idea of the present application are within the scope of the present application.
