Description
Technical Field
[0001] This utility model relates to the field of coloring device technology, specifically a coloring device for the surface of 3D printed parts. Background Technology
[0002] 3D printing, also known as additive manufacturing technology, is a technology that manufactures solid parts by adding materials layer by layer based on three-dimensional CAD data. After the 3D printed parts are produced, a surface coloring device is needed to color the surface to make it more vibrant and lifelike.
[0003] According to the patent application CN215964226 U, "This utility model relates to the field of 3D printing painting technology in the automotive industry, and discloses an adjustable 3D printing painting device, including a base. A material conveying mechanism is provided on the inner side of the base, and a control switch is fixedly installed on the outer side of the base. A gantry moving mechanism is provided inside the base, and a sliding groove is provided at the upper end of the base. A first painting adjustment mechanism is provided on the inner side of the gantry moving mechanism. In the process of using this adjustable 3D printing painting device, the material conveying mechanism can drive the 3D printed product to move, facilitating loading and unloading and reducing the intensity of work. The gantry moving mechanism enables the left and right movement of the paint head, the first painting adjustment mechanism enables the forward and backward movement of the paint head, and the second painting adjustment mechanism enables uniform painting of the paint head. The overall design is reasonable, with low limitations, and easy to use."
[0004] Regarding the above description, the applicant believes the following issues exist:

[0029] The paint spraying mechanism 3 includes a left-right moving component 31 and a corner paint spraying component 32, with the corner paint spraying component 32 located at the bottom of the left-right moving component 31.
[0030] Furthermore, the left and right moving assembly 31 includes a stand 311, which is fixedly installed on the top of the fixed side plate frame 21. A threaded rod 312 is rotatably installed inside the stand 311. A moving block 313 is threaded on the outside of the threaded rod 312. A limit rod 314 is slidably installed inside the moving block 313. A gear 315 is fixedly installed on the left side of the threaded rod 312. A motor 316 is fixedly installed on the top of the stand 311. A gear 317 is fixedly installed on the left side of the drive shaft of the motor 316, which facilitates the adjustment of the left and right position for painting and coloring through the left and right moving assembly 31.
[0031] Furthermore, the limiting rod 314 is fixedly installed on the inner side of the upright 311, and the second gear 317 meshes with the first gear 315 to facilitate the normal rotation of the threaded rod 312.
[0032] Furthermore, the corner spray painting assembly 32 includes a motor 321, which is fixedly installed at the bottom of the moving block 313. An electric push rod 322 is fixedly installed at the bottom of the drive shaft of the motor 321. A rotation limit block 323 is fixedly installed at the bottom of the electric push rod 322. A rotating block 324 is rotatably installed inside the rotation limit block 323. A paint spray head 325 is fixedly installed at the bottom of the rotating block 324. A worm gear 326 is fixedly installed on the right side of the rotating block 324. A worm 327 meshes with the outside of the worm gear 326. A motor 328 is fixedly installed on the right side of the rotation limit block 323. A delivery pipe 329 is fixedly installed inside the paint spray head 325. A pump 3210 is fixedly installed at the end of the motor 328 away from the paint spray head 325. A suction pipe 3211 and a paint storage tank 3212 are fixedly installed at the bottom of the pump 3210, which facilitates the adjustment of the spraying angle through the corner spray painting assembly 32.
[0033] Furthermore, the bottom of the drive shaft of motor 328 is fixedly installed with the top of worm gear 327, and the bottom of paint storage tank 3212 is fixedly installed with the top of stand 311, which facilitates painting under normal conditions.
[0034] Example 2:
[0035] Please see Figure 5 Furthermore, in conjunction with Embodiment 1, the conveying mechanism 2 includes a fixed side plate frame 21, which is fixedly installed on the top of the support leg 1. A transmission roller 22 is rotatably installed inside the fixed side plate frame 21, and a transmission belt 23 is driven to the outside of the transmission roller 22. A motor 24 is fixedly installed at the bottom of the fixed side plate frame 21. Transmission rollers 25 are fixedly installed on the left side of the transmission shaft of the motor 24 and on the left side of the back transmission roller 22. A transmission belt 26 is driven to the outside of the transmission rollers 25, which facilitates the conveying of 3D printed parts through the conveying mechanism 2.
[0036] Furthermore, holes are provided at corresponding positions of the fixed side plate frame 21 and the transmission roller 22, and the transmission roller 22 is rotatably installed inside the holes provided inside the fixed side plate frame 21, which facilitates transmission under normal conditions.
[0037] In actual operation, when this device is used, the 3D printed part to be painted is placed on top of the conveyor belt 23. At this time, the drive motor 24, driven by the transmission roller 25 and the transmission belt 26, causes the transmission roller 22 to rotate. The fixed side plate frame 21 then begins to transport the 3D printed part. When it reaches the bottom of the stand 311, the drive motor 316 drives the gear 317 to rotate. At this time, the gear 315 rotates, causing the threaded rod 312 to rotate. The moving block 313 is limited by the limit rod 314. Moving the motor downwards changes the left and right position of the paint sprayer. Driving the electric push rod 322 causes the paint sprayer head 325 to move downwards, which in turn drives the pump 3210 to draw paint from the paint storage tank 3212 through the suction pipe 3211. After being conveyed, the paint is sprayed out from the paint sprayer head 325 and applied to the surface of the 3D printed part. Driving the motor 328 causes the worm gear 327 to drive the worm wheel 326 to rotate, which in turn causes the rotating block 324 to rotate the paint sprayer head 325, changing the spraying angle. Driving the motor 321 causes the paint sprayer head 325 to rotate again, which can change the position of the paint sprayer head 325 again.
