[0011] Preferably, the placement platform forms a sliding structure with the turntable through a limiting block, and the limiting block is movably connected to the sliding groove.

[0012] Preferably, the buckle forms a telescopic structure with the anti-fog lighting lamp through a reset spring, and the buckle is inserted into the slot.

[0013] Preferably, the anti-fog light is connected to the mounting bracket by a snap-fit, and the anti-fog light is magnetically fixed to the limiting plate by a magnetic block.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the setting of a drive motor, rotating shaft, slide groove, slider and turntable, allows the handicraft on the turntable to rotate by starting the drive motor and using the output shaft of the drive motor to rotate, so that the paint sprayed from the nozzle can be evenly sprayed onto the handicraft. Since the handicraft is in a continuous and uniform rotation state, the atomized paint sprayed from the nozzle can fully cover the outer surface of the handicraft. Whether it is a flat surface, curved surface or irregular shape, the paint can be evenly adhered, completely solving the problem of spraying dead corners and uneven coating caused by the fixed workpiece in the traditional spraying method; 2. This utility model, through the setting of a turntable, stepper motor, lead screw, sliding groove, placement platform and limit block, uses the stepper motor to drive the lead screw to rotate by starting the stepper motor output shaft, and can also adjust the height of the crafts. By precisely adjusting the position of the crafts, it can adapt to crafts with significant height differences, ensuring that the nozzle always maintains the optimal spraying distance with the workpiece surface, avoiding paint accumulation due to being too close or insufficient coverage due to being too far. While moving upward, it is also convenient to pick up and place the crafts. 3. This utility model, through the setting of a mounting bracket, slot, anti-fog light, limiting plate, magnetic block, return spring, and buckle, allows for operation by pulling the buckles on both sides, simultaneously compressing the return spring, inserting the anti-fog light into the mounting bracket, and then releasing the buckle. The elastic rebound of the return spring pushes the buckle into the slot for fixation. The limiting plate then restricts the movement of the buckle and allows for the installation of the anti-fog light. The anti-fog light directly illuminates the interior, enhancing the brightness and facilitating clear observation of the workpiece's coating process by operators. This allows for timely detection and resolution of potential uneven coating issues and also improves the safety of the coating operation. Disassembly can be completed by reversing the operation, eliminating the need for tools and improving maintenance efficiency. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0018] The embodiments of this utility model will be described below based on its overall structure.

[0019] Please see Figures 1-5A uniform spraying machine for producing handicrafts includes a spraying chamber 1. A drive motor 2 is fixedly connected inside the spraying chamber 1. The drive motor 2 is fixedly connected to a rotating shaft 3 via a coupling. A groove 4 is provided on the inner wall of the spraying chamber 1. A slider 5 is installed on the inner wall of the groove 4. A turntable 6 is provided on the top of the slider 5. The slider 5 and the spraying chamber 1 form a rotating structure through the rotating shaft 3, and the rotating shaft 3 is movable with the spraying chamber 1. The turntable 6 and the spraying chamber 1 form a sliding structure through the slider 5, and the slider 5 is engaged with the groove 4. When using the device, by starting the drive motor 2, the output shaft of the drive motor 2 drives the rotating shaft 3 to rotate at a uniform speed. Under the driving force of the rotating shaft 3, the slider 5 at the bottom of the turntable 6 rotates smoothly along the annular trajectory of the groove 4. The turntable 6 then drives the handicrafts above to rotate synchronously, so that the paint sprayed from the nozzle can be uniformly sprayed onto the handicrafts.

[0020] Please see Figures 1-5 A uniform spraying machine for craft production includes a turntable 6 with a stepper motor 7 fixedly connected to its inner wall. The stepper motor 7 is fixedly connected to a lead screw 8 via a coupling. A sliding groove 9 is formed on the inner wall of the turntable 6. A placement platform 10 is mounted on the outer wall of the lead screw 8. A limit block 11 is provided on the side wall of the placement platform 10. The placement platform 10 is threadedly connected to the lead screw 8, and the lead screw 8 and turntable 6 form a rotating structure via the stepper motor 7. The placement platform 10 and turntable 6 form a sliding structure via the limit block 11, and the limit block 11 is movably connected to the sliding groove 9. When using the device, the stepper motor 7 is activated. Motor 7, using the output shaft of stepper motor 7, drives lead screw 8 to rotate forward or reverse. Since lead screw 8 is threadedly connected to placement platform 10, the rotational motion of lead screw 8 is converted into the axial linear motion of placement platform 10. Driven by the rotation of lead screw 8, placement platform 10 slides up and down along sliding groove 9 using limit block 11, and can adjust the height of handicrafts. By precisely adjusting the position of handicrafts, it can better adapt to handicrafts of different shapes and sizes, ensuring uniform coating coverage. While moving upward, it also facilitates the picking up and placing of handicrafts.

[0021] Please see Figures 1-5A uniform spraying machine for producing handicrafts includes a spraying chamber 1 with an inner wall mounting frame 12. The side wall of the mounting frame 12 has a slot 13. An anti-fog light 14 is mounted on the outer wall of the mounting frame 12. A limit plate 15 is mounted on the top of the anti-fog light 14. Magnets 16 are located on the top of the anti-fog light 14 and the bottom of the limit plate 15. A return spring 17 is located on the inner wall of the anti-fog light 14. A buckle 18 is located at one end of the return spring 17. The buckle 18 and the anti-fog light 14 form a telescopic structure through the return spring 17, and the buckle 18 is inserted into the slot 13. The anti-fog light 14 is engaged with the mounting frame 12 through the buckle 18, and the anti-fog light 14 is magnetically fixed to the limit plate 15 through the magnet 16. When using the device, pull the two side latches 18 to move them inward along the guide groove inside the anti-fog light 14, while compressing the return spring 17. Then insert the anti-fog light 14 into the mounting bracket 12 until the latches 18 are aligned with the slots 13. Then release the latches 18, and use the elastic rebound of the return spring 17 to push the latches 18 into the slots 13 for fixation. Then fix the limiting plate 15 to the anti-fog light 14 with the magnetic block 16 to restrict the movement of the latches 18, prevent the latches 18 from disengaging from the slots 13 due to misoperation, and allow the anti-fog light 14 to be installed. The anti-fog light 14 can directly illuminate the processing area. Then reverse the operation to complete the disassembly without the use of tools, improving maintenance efficiency.

[0022] Working principle: In use, first move the device to a suitable position, pull the two side buckles 18 to compress the return spring 17, and then insert the anti-fog light 14 into the mounting bracket 12. At this time, the buckles 18 are aligned with the slots 13. Then release the buckles 18, and use the elastic rebound of the return spring 17 to push the buckles 18 into the slots 13 for fixation. Then fix the limiting plate 15 to the anti-fog light 14 with the magnetic block 16, and the anti-fog light 14 can be installed. The anti-fog light 14 can directly illuminate the inside of the compartment. Then reverse the operation to complete the disassembly. Then start the stepper motor 7, and use the output shaft of the stepper motor 7 to drive the lead screw 8 to rotate. Since the lead screw 8 is threadedly connected to the placement platform 10, under the drive of the rotation of the lead screw 8, the placement platform 10 is driven by the limiting block 11 to move along the sliding groove 9. Slide the device upwards and place the craft on the placement platform 10. Then, start the stepper motor 7 to rotate in the reverse direction, moving the placement platform 10 downwards to collect the craft into the compartment. Then, start the spraying process to spray the craft. At the same time, the stepper motor 7 can be started again to move the placement platform 10 up and down to adjust the height of the craft and ensure that the paint is evenly covered. Then, start the drive motor 2, and use the output shaft of the drive motor 2 to drive the rotating shaft 3 to rotate. Driven by the rotation of the rotating shaft 3, the turntable 6 rotates along the slide groove 4 using the slider 5, which can rotate the craft on the turntable 6 so that the paint sprayed from the nozzle can be evenly sprayed onto the craft. This completes the use of the device. The contents not described in detail in this specification are existing technologies known to those skilled in the art.
