[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1 to 6 As shown, the injection molding machine spraying device provided by the present invention includes a bottom plate 1, a spraying head 2, and a conveyor belt 5. A flipping mechanism is fixedly connected to the top end of the bottom plate 1. The flipping mechanism is connected to the bottom end of the spraying mechanism. A clamping device is fixedly connected inside the flipping mechanism. It is characterized in that:

[0027] A conveyor belt 5 is fixedly connected inside the bottom plate 1. A flipping mechanism is arranged at the top end of the conveyor belt 5. Two groups of extension plates 11 are fixedly connected to the top end of the bottom plate 1. A column 14 is fixedly connected to the top end of the extension plate 11. The spraying head 2 is arranged at the bottom end of the middle part of the column 14.

[0028] The workpiece is transferred to a suitable position through the transmission of the conveyor belt 5. The workpiece is sprayed by the spraying head 2. After one side is sprayed, the clamping device is started to clamp the workpiece placed on the top of the heightening plate 25. Subsequently, the flipping mechanism is started to flip it. After the flipping is completed, the clamping of the workpiece is cancelled. After the conveyor belt 5 moves the workpiece to a suitable position, the spraying head 2 is started again to spray the back of the workpiece, so as to achieve all-round spraying.

[0029] The clamping device includes a flipping plate 4. A chute is opened inside the flipping plate 4. Two groups of clamping plates 13 are slidably sleeved inside the chute. One end of a transmission plate 20 is hinged to the back of the clamping plate 13. The other end of the transmission plate 20 is hinged to a transmission plate 21. The outer wall of a transmission shaft 24 is fixedly connected inside the two groups of transmission plates 21. The outer wall of the transmission shaft 24 is movably sleeved with the flipping plate 4. The output end of a motor 22 is fixedly connected to the back of the transmission shaft 24. A connecting block 23 is fixedly connected to the back of the motor 22. The protruding end of the connecting block 23 is fixedly connected to the back of the flipping plate 4.

[0030] Start the motor 22. The output end of the motor 22 drives the two groups of transmission plates 21 to rotate around the transmission shaft 24, thereby driving the two sides of the transmission plate 20 to rotate synchronously, and further driving the two groups of clamping plates 13 to slide inside the flipping plate 4, so as to simply and stably clamp the workpiece on the top of the heightening plate 25.

[0031] The flipping mechanism includes two groups of second connecting rods 12. A flipping plate 4 is fixedly connected to the back surface of the second connecting rods 12. First connecting rods 8 are fixedly connected to the front surfaces of the two groups of second connecting rods 12. An extension plate 11 is movably sleeved on the outer walls of the two groups of first connecting rods 8. A bottom plate 1 is fixedly connected to the bottom end of the extension plate 11. A gear 7 is fixedly connected to the outer wall of one of the first connecting rods 8. The bottom end of the gear 7 meshes with the surface of a toothed plate 9. A connecting plate 10 is fixedly connected to the front surface of the toothed plate 9. The output end of a hydraulic telescopic rod 3 is fixedly connected to the outer wall of the connecting plate 10.

[0032] A chute plate 6 is fixedly connected to the top end of the bottom plate 1. The toothed plate 9 is slidably sleeved inside the chute plate 6.

[0033] After the clamping device finishes clamping, start the hydraulic telescopic rod 3. The output end of the hydraulic telescopic rod 3 drives the connecting plate 10 to move synchronously, thereby pulling the toothed plate 9 to slide on the top end of the chute plate 6, making the toothed plate 9 mesh with the gear 7, driving the gear 7 to rotate around the first connecting rod 8 as the center, further driving the second connecting rod 12 to pull the flipping plate 4 to rotate around the first connecting rod 8 as the center, so as to drive the workpiece clamped on the outer wall of the flipping plate 4 to flip and spray the reverse side.

[0034] The spraying mechanism includes a column 14. An extension plate 11 is fixedly connected to the bottom end of the column 14. An arc-shaped block 26 is fixedly connected inside the column 14. The arc-shaped block 26 is arc-shaped. An arc-shaped chute is opened inside the arc-shaped block 26, and a slider 19 is slidably sleeved inside the arc-shaped chute. A spraying head 2 is fixedly connected to the bottom end of the slider 19.

[0035] An extension plate 2 is fixedly connected to the top end of the column 14. A first motor 15 is fixedly connected to the front surface of the extension plate 2. The output end of the first motor 15 is fixedly connected to a swinging chute 17. A limiting chute is opened inside the swinging chute 17, and a third connecting rod 18 is slidably sleeved inside the limiting chute. A slider 19 is fixedly connected to the front surface of the third connecting rod 18. The third connecting rod 18 is slidably sleeved on the outer wall of the arc-shaped block 26.

[0036] When spraying, start the first motor 15. The output end of the first motor 15 drives the swinging chute 17 to swing and rotate around the first motor 15 as the center. When the swinging chute 17 swings, it drives the third connecting rod 18 slidably sleeved inside to slide inside the arc-shaped block 26, further driving the slider 19 to slide synchronously, so that the spraying head 2 at the bottom end of the slider 19 slides along the bottom arc of the arc-shaped block 26, increasing the spraying angle, thereby spraying the sides of different workpieces, which can better control the spraying direction and spraying intensity of the paint and helps to form a smoother and more uniform coating.

[0037] Two groups of elevation plates 25 are fixedly connected to the top of the conveyor belt 5. The height of the elevation plates 25 is higher than that of the lower set of clamping plates 13. The elevation plates 25 raise the workpiece to a height higher than the top of the clamping plates 13, thus facilitating the clamping of the workpiece by the clamping plates 13.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
