Detailed Implementation
[0024] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings, so that those skilled in the art can more clearly understand how to practice this utility model. Although this utility model has been described in conjunction with its preferred embodiments, these embodiments are merely illustrative and not intended to limit the scope of this utility model.
[0025] Combined with appendix Figures 1-4 As shown, a coloring device for wooden toy production includes a conveying platform 1 and a support frame 3 mounted above the conveying platform 1. Multiple open-topped coloring boxes 2 are placed on the conveying platform 1. Each coloring box 2 contains a coloring chamber 12, and a tray 13 is installed inside the coloring chamber 12. The tray 13 is made of elastic polyurethane material to prevent bumps and knocks to the toys to be painted. An electric rotating platform is installed at the bottom of the tray 13, and a fixed column 14 is installed in the middle of the tray 13. A top plate 6 is installed on the top of the support frame 3. A lifting cylinder 19 and a workpiece positioning sensor are installed at the bottom of the top plate 6. A connecting rod 7 is installed at the bottom of the lifting cylinder 19, and a coloring cover 8 is connected to the bottom of the connecting rod 7. A coloring cavity 17 is provided inside the coloring cover 8. Multiple nozzles 16 are arranged circumferentially on the top of the coloring cavity 17. The nozzles 16 are electric low-pressure nozzles. Corresponding air regulating valves and paint regulating valves are provided for the nozzles 16 to regulate the air and paint flow rates, respectively.
[0026] The workpiece positioning sensor is used to detect whether the tray 13 is exactly below the coloring mask 8. The workpiece positioning sensor is electrically connected to an external industrial control computer. When it detects that the tray 13 is directly below the coloring mask 8, it transmits a positioning signal to the external industrial control computer, which then controls the conveyor platform 1 to stop conveying so that the coloring process can proceed. The workpiece positioning sensor includes, but is not limited to, CCD vision sensors, infrared sensors, etc.
[0027] Specifically, the conveyor platform 1 is equipped with a belt, and fixed blocks 21 are spaced apart on the belt. The bottom of the coloring box 2 is equipped with a slot, which engages with the fixed blocks 21 to stabilize the position of the coloring box 2 on the belt.
[0028] Specifically, the bottom of the coloring chamber 12 is provided with an annular groove 15, and the bottom of the coloring cover 8 is engaged in the annular groove 15. That is, the coloring cover 8 can stably cover the tray 13 by engaging with the annular groove 15.
[0029] Specifically, a conveying pipe 18 is provided on the outer side of the top of the coloring hood 8, and the bottom of the conveying pipe 18 is connected to a plurality of nozzles 16.
[0030] Specifically, a dye box 4 is installed on one side of the top plate 6. The dye box 4 contains spray paint. A liquid delivery pipe 20 is connected to the bottom of the dye box 4. One end of the liquid delivery pipe 20 is connected to the delivery pipe 18. The liquid delivery pipe 20, in conjunction with the delivery pipe 18, delivers the spray paint to the nozzle 16.
[0031] Specifically, a rotary motor 5 is installed on the top of the dye box 4, and a stirring shaft is driven to the bottom of the rotary motor 5. The stirring shaft is located inside the dye box 4, and multiple stirring rods are symmetrically arranged on the stirring shaft. The stirring shaft and stirring rods are not shown. By starting the rotary motor 5, the stirring rods on the stirring shaft are rotated to prevent the paint material in the dye box 4 from depositing and to improve the uniform coloring of the toys in the future.
[0032] Specifically, a drive assembly 11 is installed on one side below the conveyor platform 1. The conveyor platform 1 is a long-distance belt conveyor, meaning the conveying distance of the belt is relatively long. After the coloring process, a drying device can be installed at the rear of the conveyor platform 1 so that the colored toys can directly enter the drying process. The drive assembly 11 contains a drive motor, which provides power to the conveyor platform.
[0033] Specifically, baffles 9 are symmetrically installed on both sides of the conveying platform 1. The baffles 9 help to prevent the coloring box 2 from falling off the side of the conveying platform 1.
[0034] Specifically, support rods 10 are installed at both ends of the conveying platform 1, and the support rods 10 provide support for the conveying platform 1.
[0035] Specifically, the entire coloring device is electrically connected to an external industrial control computer, that is, the electric rotary table, lifting cylinder 19, nozzle 16, rotary motor 5 and drive assembly 11 are electrically connected to an external industrial control computer.
[0036] Furthermore, the fixing post 14 is configured according to whether the bottom of the toy to be painted has a fixing groove. The fixing post 14 is threadedly connected to the tray 13, meaning that the fixing post 14 is detachable. All toys to be painted according to this invention have a fixing groove on their bottom.
[0037] The specific working principle of this utility model is as follows:
[0038] Multiple toys to be colored are placed on tray 13 and secured by fixing posts 14. At this time, the coloring box 2, where tray 13 is located, is stably placed on the conveyor belt 1 via fixing block 21 and slot engagement. An external industrial control computer controls the drive motor in drive assembly 11 to feed the conveyor belt 1. When the workpiece positioning sensor detects that tray 13 is directly below the coloring cover 8, it sends a positioning signal to the external industrial control computer. The computer then stops the drive motor and belt, and drives the lifting cylinder 19 to push the connecting rod 7 to lower the coloring cover 8 until it is engaged at the bottom of the annular groove 15. Multiple nozzles 16 then spray the toys. Simultaneously, an electric rotary table slowly rotates tray 13 to ensure even coloring. After coloring, the lifting cylinder 19 raises the coloring cover 8. The external industrial control computer controls the drive motor and belt to rotate, and the coloring box 2 moves forward to enter the drying process. Alternatively, the coloring box 2 can be removed and transferred to a drying rack.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and substitutions based on the technical solutions and inventive concepts provided by the present utility model should be covered within the protection scope of the present utility model.
