Description

Technical Field

[0001] The utility model relates to the technical field of wooden door processing, in particular to a painting device for manufacturing wooden doors. Background Technique

[0002] The painting devices used in the process of manufacturing wooden doors are usually specially designed spraying equipment for evenly spraying paint on the surface of wooden doors to achieve the effects of beauty and protection. These painting devices can be manually operated or automated, depending on the production scale and process requirements.

[0003] Currently, the painting devices for manufacturing wooden doors usually clamp both ends of the wooden door to hang the wooden door, and then use a spray gun to evenly spray the surface of the wooden door. However, usually, the spray gun can only spray one side of the wooden door. After the single-sided painting of the wooden door is completed, the wooden door needs to be manually or electrically flipped to spray the other side of the wooden door, resulting in low painting efficiency and being not conducive to improving the overall processing efficiency.

[0004] In view of the above problems, the present utility model document proposes a painting device for manufacturing wooden doors. Content of the Utility Model

[0005] The utility model provides a painting device for manufacturing wooden doors, which solves the disadvantages in the prior art that the spray gun can only spray one side of the wooden door, and after the single-sided painting of the wooden door is completed, the wooden door needs to be manually or electrically flipped to spray the other side of the wooden door, resulting in low painting efficiency and being not conducive to improving the overall processing efficiency.

[0032] Embodiment 1

[0033] Please refer to Figures 1-4 , a painting device, comprising:

[0034] The device mainly consists of an L-shaped support frame 1 and a double-sided painting assembly. A clamping box body 2 is fixedly arranged at the top of the L-shaped support frame 1 for clamping a wooden door. At both ends of the inner wall of the clamping box body 2, a bidirectional threaded screw rod 3 is rotatably installed. A first driving motor 4 is fixedly installed on its outer wall for driving the rotation of the bidirectional threaded screw rod 3. Inside the clamping box body 2, two screw rod seats 5 are symmetrically connected to the bidirectional threaded screw rod 3. The screw rod seat 5 penetrates through the box opening on one side of the clamping box body 2 and is fixedly provided with a Z-shaped connecting frame 6. Two clamping rods 7 are symmetrically and fixedly arranged inside the Z-shaped connecting frame 6 for clamping the wooden door. When the first driving motor 4 drives the bidirectional threaded screw rod 3 to rotate, the two screw rod seats 5 will move towards or away from each other, thereby driving the Z-shaped connecting frame 6 and the clamping rods 7 to clamp or loosen the wooden door;

[0035] The double-sided painting assembly includes two mounting frames 8 symmetrically arranged above and below the wooden door. A plurality of paint spray heads 9 are equidistantly installed on the opposite surfaces of each mounting frame 8 for painting both sides of the wooden door. One end of the two mounting frames 8 is fixedly connected to the same U-shaped connecting frame 10 to ensure the stability and synchronism of the painting assembly. The plurality of paint spray heads 9 are all connected to an external paint supply bucket through paint conveying pipes to ensure the continuous supply of paint during the painting process. By controlling the flow rate and pressure of the paint conveying pipes, precise control of the painting effect can be achieved;

[0036] To improve the uniformity and flexibility of paint spraying, a chassis 11 is provided outside the L-shaped support frame 1. A plurality of rollers 12 are fixedly installed at equal intervals at the bottom of the chassis 11, facilitating the movement and alignment of the double-sided paint spraying assembly with the wooden door. A regulating box body 13 is fixedly arranged at the top of the chassis 11, which is used to drive the double-sided paint spraying assembly to perform uniform paint spraying. At both ends of the inner wall of the regulating box body 13, threaded rods 14 are rotatably installed. A second driving motor 16 is fixedly installed on its outer wall, which is used to drive the rotation of the threaded rod 14. A sliding seat 15 is threadedly connected to the threaded rod 14. The sliding seat 15 passes through the box opening on one side of the regulating box body 13 and is fixedly connected to the center of one side of the U-shaped connecting frame 10. When the second driving motor 16 drives the threaded rod 14 to rotate, the sliding seat 15 will move along the threaded rod 14, thereby driving the double-sided paint spraying assembly to move and simultaneously spray the two sides of the wooden door evenly.

[0037] Regarding the control programs and circuit structures involved in the present utility model, those skilled in the art can all achieve them according to the same or similar principles in the prior art. This part is not the innovation of the present utility model.

[0040] A paint spraying device for manufacturing wooden doors, which is applied in the field of wooden door processing;

[0041] Please refer to Figure 1 and Figure 4 , a T-shaped frame 17 is provided outside the chassis 11. The T-shaped frame 17 is fixed to the ground by a plurality of bolts. A central position on one side of the T-shaped frame 17 is fixedly provided with an electric push rod 18, and its output end is fixedly connected to the central position on one side of the chassis 11. By the telescopic movement of the electric push rod 18, the chassis 11 can be driven to move back and forth, thus facilitating the adjustment of the paint spraying position and enabling the double-sided paint spraying assembly to align with the wooden door, eliminating the need to manually move the chassis 11, which is convenient to use.

[0042] However, as is well known to those skilled in the art, the working principles and wiring methods of the first driving motor 4, the second driving motor 16, and the electric push rod 18 are common knowledge.
