DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. 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.

[0021] In a specific implementation, as shown in the accompanying drawings, Figures 1-4 An automatic powder spraying device for feeding and discharging, comprising a powder spraying chamber 100, an overhead rail 200 and a self-propelled electric hoist 300, the self-propelled electric hoist 300 is installed on the overhead rail 200, and a group of spray heads 110 are arranged inside the powder spraying chamber 100; a receiving mechanism 400, the number of the receiving mechanism 400 is two, and the receiving mechanism 400 is arranged below the self-propelled electric hoist 300; the receiving mechanism 400 comprises an arc-shaped pipe 410 and an arc-shaped rod 420, one end of the arc-shaped rod 420 is slidably connected to the inside of the arc-shaped pipe 410, and a receiving plane is arranged on the outer side of the end of the arc-shaped rod 420 away from the arc-shaped pipe 410.

[0022] As shown in the accompanying drawings, Figure 2 , Figure 3 and Figure 4 The receiving mechanism 400 further comprises a vertical pipe 430, the bottom end of the vertical pipe 430 communicates with the arc-shaped pipe 410, a metal block 440 is slidably connected to the inside of the vertical pipe 430, and a connecting rope 450 is arranged between the metal block 440 and the arc-shaped rod 420; a speed regulating motor 310 is installed at the bottom of the self-propelled electric hoist 300, a magnetic strip 320 is installed at the bottom of the speed regulating motor 310, and the arc-shaped pipe 410 is fixedly installed on the outer side of the output shaft of the speed regulating motor 310.

[0023] The arc-shaped tube 410 and the arc-shaped rod 420 form a hook, and since the number of the supporting mechanisms 400 is two, the workpiece is double-hung, and the supporting flat surface is arranged to improve the supporting stability. The trolley 200 is arranged with the electric hoist 300 to complete the driving in the powder spraying process. Then, the electric hoist 300 drives the speed regulating motor 310 to move towards the inside of the powder spraying chamber 100. When the speed regulating motor 310 moves to the powder spraying area of the spray head 110, the magnetic strip 320 at the bottom of the speed regulating motor 310 is aligned with the metal block 440 above the arc-shaped tube 410. Then, under the influence of the magnetic attraction, the metal block 440 moves upwards along the stand pipe 430. In the process of movement, the connecting rope 450 pulls the arc-shaped rod 420 on the arc-shaped tube 410 to move, so that the arc-shaped rod 420 is accommodated in the arc-shaped tube 410. At this time, the arc-shaped rod 420 is separated from the workpiece, so that the area between the workpiece and the spray head 110 is not easily blocked, the powder spraying dead angle is reduced, the powder spraying uniformity is ensured, and then the arc-shaped tube 410 moves out of the powder spraying area of the spray head 110 under the driving of the speed regulating motor 310. At this time, the magnetic strip 320 and the metal block 440 in the arc-shaped tube 410 are staggered, and then the metal block 440 is not affected by the magnetic force, and then the arc-shaped rod 420 is reset. At this time, the workpiece is supported, and at the same time, the other arc-shaped tube 410 moves to the powder spraying area of the spray head 110. Then, the above movement is repeated, that is, the two arc-shaped rods 420 alternately complete the supporting work, which reduces the dead angle in the powder spraying process without affecting the supporting effect.

[0024] As shown in Figure 1 and Figure 2 , the outside of the powder spraying chamber 100 is respectively provided with a powder box and a driving pump. The driving pump is installed on the powder box. The output end of the driving pump is provided with a material guide pipe. The material guide pipe extends to the inside of the powder spraying chamber 100. The spray head 110 is installed on the material guide pipe.

[0025] The driving pump guides the powder in the powder box along the material guide pipe into the spray head 110, and then sprays it to the outside of the workpiece along the spray head 110 to complete the powder spraying work.

[0026] As shown in Figure 4 , the outside of the connecting rope 450 is provided with a spring 460. One end of the spring 460 is fixedly connected with the arc-shaped rod 420. The other end of the spring 460 is installed on the inner wall of the arc-shaped tube 410.

[0027] With the arrangement of the spring 460, when the corresponding arc-shaped rod 420 is received, after the arc-shaped rod 420 leaves the powder spraying area of the spray head 110, the magnetic stripe 320 no longer attracts the corresponding metal block 440, and then the arc-shaped rod 420 is no longer subjected to the traction force, and then the spring 460 can drive the arc-shaped rod 420 to move to the original position, and the workpiece is again supported, and then another arc-shaped rod 420 moves to the spray head 110 area to perform the receiving movement, and the two arc-shaped rods 420 alternately complete the receiving and supporting work of the workpiece, which ensures the support of the workpiece and reduces the dead angle during the powder spraying process.

[0028] As shown in Figure 4 The outer side of the connecting rope 450 is in contact with the outer side of the guide roller.

[0029] With the arrangement of the guide roller, the friction between the connecting rope 450 and the connecting position of the vertical pipe 430 and the arc-shaped pipe 410 can be reduced, and the service life of the connecting rope 450 can be prolonged.

[0030] As shown, the vertical pipe 430 is internally provided with a limiting groove in sliding connection with the metal block 440.

[0031] The metal block 440 is limited by the sliding groove, which reduces the over-movement phenomenon and ensures the stability during the up-down movement.

[0032] Working principle: the arc-shaped pipe 410 and the arc-shaped rod 420 form a hook to double-hang the workpiece, and the arrangement of the supporting plane improves the supporting stability, and the trolley 200 is matched with the electric hoist 300 to complete the driving during the powder spraying process, and then the electric hoist 300 drives the speed regulating motor 310 to move to the inside of the powder spraying chamber 100.

[0033] It should be noted that the user can complete the arrangement and hanging of the workpiece outside the powder spraying chamber 100, and the workpiece can be transferred and processed at the powder spraying terminal, and the automatic feeding and discharging is performed during the entire powder spraying process, which reduces the number of workers required in the powder spraying chamber 100.

[0034] When moving to the powder spraying area of the spray head 110, the speed regulating motor 310 drives the workpiece to rotate slowly, when the first arc-shaped tube 410 is about to move to the spraying area of the spray head 110, at this time the magnetic strip 320 at the bottom of the speed regulating motor 310 will be aligned with the metal block 440 above the arc-shaped tube 410, then affected by the magnetic attraction force, the metal block 440 moves upward along the vertical tube 430, in the process of movement, the connecting rope 450 will pull the arc-shaped rod 420 on the arc-shaped tube 410 to move, so that the arc-shaped rod 420 is stored inside the arc-shaped tube 410, at this time the arc-shaped rod 420 is separated from the workpiece, so as not to easily block the area between the workpiece and the spray head 110, reduce the dead angle of powder spraying, ensure the uniformity of powder spraying, then with the driving of the speed regulating motor 310, the arc-shaped tube 410 moves out of the spraying area of the spray head 110, at this time the magnetic strip 320 intersects with the metal block 440 in the arc-shaped tube 410, then the metal block 440 is not affected by the magnetic force, then the arc-shaped rod 420 resets, at this time the workpiece is supported, at the same time, another arc-shaped tube 410 will move to the spraying area of the spray head 110, then repeat the above movement, that is, two arc-shaped rods 420 alternately complete the supporting work, which reduces the dead angle existing in the powder spraying process without affecting the supporting effect, ensures the uniformity of powder spraying, and the whole device has good practicability.

[0035] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
