DETAILED DESCRIPTION

[0027] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] refer to Figures 1 to 10 :

[0029] A ductile iron product spraying processing device includes a frame 1, a conveyor belt 2 arranged on the frame 1, a plurality of hanging seats 3 fixedly arranged on the conveyor belt 2, a spraying mechanism arranged beside the frame 1, a rotating mechanism arranged on each hanging seat 3 and a vibrating mechanism arranged on the frame 1, the spraying mechanism includes a spraying output end for spraying a workpiece, the rotating mechanism includes a rotating output end and a hanging hook 23 connected to the rotating output end, and the vibrating mechanism includes a vibrating output end, and the vibrating output end is used to vibrate the hanging hook 23 up and down.

[0030] When the device is in operation, the conveyor belt 2 drives several lifting seats 3 to move in an elliptical motion trajectory, and each lifting hook 23 is hoisted with a workpiece that needs to be sprayed. After that, the rotating mechanism and the spraying mechanism operate simultaneously, and the spraying mechanism sprays the surface of the workpiece. At the same time, the rotating mechanism drives the workpiece to rotate to ensure that the surface of the workpiece can be sprayed evenly. Then the vibration mechanism operates to drive the workpiece to shake up and down, so that excess spray liquid on the surface of the workpiece falls off, thereby completing the spraying of the workpiece.

[0031] In order to show the detailed structure of the rotating mechanism, the following features are also set:

[0032] Each rotating mechanism includes a connecting seat 12 fixedly connected to the lifting seat 3, a rotating shaft 13 rotatably arranged in the connecting seat 12, and a mounting plate 25 (such as Figure 8 ), rotating the transmission gear 26 (as shown in FIG. Fig.10 As shown), a transfer gear 14 coaxially connected to the rotating shaft 13, a receiving tube 15 coaxially connected to the rotating shaft 13, a transmission rack 27 fixedly arranged on the frame 1, and a lifting hook 23 connected to the receiving tube 15, the lifting hook 23 is used to lift and fix the workpiece, the transfer gear 14 is meshed with the transmission gear 26, and the receiving tube 15 is the rotating output end of the rotating mechanism.

[0033] When the conveyor belt 2 drives the lifting seat 3 to move, the transmission gear 26 meshes with the transmission rack 27, thereby causing the transmission gear 26 to rotate. The rotation of the transmission gear 26 drives the transfer gear 14 to rotate. The rotation of the transfer gear 14 causes the rotating shaft 13 to rotate. The rotation of the rotating shaft 13 drives the receiving tube 15 to rotate. The rotation of the receiving tube 15 drives the lifting hook 23 to rotate. The rotation of the lifting hook 23 drives the workpiece to rotate.

[0034] In order to show the connection structure between the receiving pipe 15 and the lifting hook 23, the following features are also specifically provided:

[0035] A plurality of limiting grooves 16 are provided in an annular manner on the inner wall of each receiving tube 15, a connecting plate 18 is slidably provided in each receiving tube 15, a connecting rod 20 is coaxially fixedly provided on the connecting plate 18, a reset spring 17 is provided on the connecting plate 18, a sealing ring 24 is fixedly provided at the bottom end of each receiving tube 15, a plurality of limiting strips 19 are provided in an annular manner on each connecting plate 18, a lifting hook 23 is fixedly provided at the bottom end of the connecting rod 20, the limiting grooves 16 correspond to the limiting strips 19 one by one, one end of the reset spring 17 is connected to the receiving tube 15, and the other end is connected to the connecting plate 18, and the connecting rod 20 is transmission-connected to the vibration output end of the vibration mechanism.

[0036] When the device is running, the receiving tube 15 drives the connecting disk 18 to rotate, and the rotation of the connecting disk 18 drives the connecting rod 20 to rotate, and the rotation of the connecting rod 20 causes the lifting hook 23 to rotate. During this process, the cooperation between the limit groove 16 and the limit bar 19 ensures that the receiving tube 15 can always drive the connecting rod 20 to rotate, and when the vibration output end of the vibration mechanism drives the connecting rod 20 to move up and down, the reset spring 17 can ensure that the connecting rod 20 can flexibly extend and retract in the receiving tube 15.

[0037] In order to show the detailed structure of the vibration mechanism, the following features are also set:

[0038] The vibration mechanism includes a limiting ring plate 4 fixedly arranged on the frame 1, a protective shell 5 fixedly connected to the frame 1, a limiting convex ring 6 fixedly arranged at the bottom of the protective shell 5, a plurality of receiving ring boxes 28 slidably connected to the limiting convex ring 6, and a limiting tube 29 (such as a convex ring 29) fixedly arranged in each receiving ring box 28. Fig.10 As shown), a limiting vertical plate 32 fixedly arranged on each receiving ring box 28, a sliding vertical groove 33 opened on the limiting vertical plate 32, a receiving rod 34 slidably connected to the sliding vertical groove 33, a roller 35 rotatably arranged on the receiving rod 34, a connecting plate 36 fixedly arranged on the receiving rod 34, a positioning slide 37 fixedly arranged on the frame 1 and a wave slide 38 opened on the positioning slide 37 (as shown Figure 6 As shown in the figure, one end of the connecting plate 36 is fixedly connected to the receiving rod 34, and the other end is fixedly connected to the connecting rod 20. The limiting tube 29 is slidably connected to the connecting rod 20. The receiving rod 34 is the vibration output end of the vibration mechanism. The roller 35 is slidably matched with the wave slide groove 38, and the receiving ring box 28 is slidably matched with the limiting ring plate 4 and the limiting convex ring 6.

[0039] When the device is running, the connecting rod 20 is driven by the conveyor belt 2 to move, and the connecting rod 20 contacts the limiting tube 29, causing the receiving ring box 28 to move along the limiting convex ring 6, thereby causing the limiting vertical plate 32 to move together with the receiving ring box 28, and the movement of the limiting vertical plate 32 drives the receiving rod 34 to move. When a receiving rod 34 moves to the positioning slide plate 37, the roller 35 contacts the wave slide groove 38, and as the roller 35 moves in the wave slide groove 38, the receiving rod 34 moves up and down, and the movement of the receiving rod 34 drives the connecting plate 36 to move up and down. The up and down movement of the connecting plate 36 causes the connecting rod 20 to move up and down, thereby causing the lifting hook 23 to drive the workpiece to shake up and down (it should be noted that the movement trajectory of the receiving ring box 28 only moves along the gap between the limiting convex ring 6 and the limiting ring plate 4, and the movement trajectory of the connecting rod 20 is to slide up and down in the limiting tube 29 or be driven to rotate by the receiving tube 15).

[0040] In order to show the connection relationship between the limit tube 29 and the connecting rod 20, the following features are also specifically provided:

[0041] A fixing ring 21 is coaxially fixedly disposed on each connecting rod 20 , and a plurality of balls 22 are rotatably disposed on each fixing ring 21 , and the balls 22 are in contact with the inner wall of the limiting tube 29 .

[0042] When the connecting rod 20 is driven by the connecting plate 36 to move up and down, the ball 22 contacts the inner wall of the limiting tube 29 to reduce friction and ensure that the connecting rod 20 can move smoothly.

[0043] In order to ensure that the workpiece surface can dry as quickly as possible after spraying, the following features are also set:

[0044] A plurality of air outlet holes 31 are formed on each receiving ring box 28 . An air cylinder 39 is also fixedly disposed on each receiving ring box 28 . Each air cylinder 39 corresponds to and is fixedly connected to each receiving rod 34 .

[0045] When the receiving rod 34 moves up and down, the receiving rod 34 drives the air cylinder 39 to operate, and the air cylinder 39 pumps gas into the receiving ring box 28, and then sprays it out from the air outlet 31, so that wind will blow toward the workpiece when the workpiece shakes up and down, accelerating the fixation of the liquid on the surface of the workpiece. A one-way valve is arranged in the receiving ring box 28, and this one-way valve ensures that gas is sprayed out from the air outlet 31 only when the air cylinder 39 is compressed.

[0046] In order to show the detailed structure of the spraying mechanism, the following features are also set:

[0047] The spraying mechanism includes a spraying frame 7 fixedly arranged on the side of the frame 1, a plurality of nozzles 8 arranged on the spraying frame 7, a nozzle 9 fixedly arranged on each nozzle 8, a delivery pipe 10 arranged on the spraying frame 7 and a spraying protective cover 11 arranged on the spraying frame 7, and the delivery pipe 10 is connected to an external liquid storage tank.

[0048] When the device is running, the spray liquid enters the nozzle 8 from the delivery pipe 10, and then is sprayed out from the nozzle 9 to spray the workpiece passing through the nozzle 9. The setting of the spray protection cover 11 prevents the spray liquid from spilling and ensures the normal progress of the spraying process.

[0049] In order to ensure that the connecting rod 20 can be kept clean when the device is running, the following features are also provided:

[0050] An annular brush 30 is fixedly disposed at the bottom of the limiting tube 29 .

[0051] When the connecting rod 20 moves up and down, the annular brush 30 can clean the outer wall of the connecting rod 20 at all times to prevent the spraying liquid from accumulating on the connecting rod 20 .

[0052] The working principle of this device is as follows: the conveyor belt 2 drives the lifting seat 3 to rotate, and when the transmission gear 26 contacts the transmission rack 27, the transmission gear 26 meshes with the transmission rack 27, thereby causing the transmission gear 26 to rotate, and the rotation of the transmission gear 26 drives the transfer gear 14 to rotate, and the rotation of the transfer gear 14 causes the rotating shaft 13 to rotate, and the rotation of the rotating shaft 13 drives the receiving tube 15 to rotate, and the receiving tube 15 drives the connecting disk 18 to rotate, and the rotation of the connecting disk 18 drives the connecting rod 20 to rotate, and the rotation of the connecting rod 20 causes the lifting hook 23 to rotate. During this process, the cooperation of the limit groove 16 and the limit strip 19 ensures that the receiving tube 15 can always drive the connecting rod 20 to rotate, and at the same time, the spray liquid enters the nozzle 8 from the conveying pipe 10, and then is sprayed out from the nozzle 9 to spray the workpiece passing through the nozzle 9. As the conveyor belt 2 continues to move, the roller 35 conflicts with the wave chute 38, and as the roller 35 moves in the wave chute 38, the receiving rod 34 moves up and down, and the movement of the receiving rod 34 drives the connecting plate 36 to move up and down, and the up and down movement of the connecting plate 36 causes the connecting rod 20 to move up and down, so that the lifting hook 23 drives the workpiece to shake up and down. When the receiving rod 34 moves up and down, the receiving rod 34 drives the air cylinder 39 to operate, and the air cylinder 39 operates to pump gas into the receiving ring box 28, and then sprays it out from the air outlet 31, so that when the workpiece shakes up and down, wind will blow towards the workpiece, accelerating the solidification of the liquid on the surface of the workpiece, thereby completing the spraying work on the workpiece.

[0053] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
