[0002] In the modern decorative materials and furniture manufacturing industry, melamine-impregnated paper is an important surface decoration material. With its rich variety of colors, good environmental performance and relatively low cost, it is widely used in furniture veneers, interior decoration boards and other fields. In order to improve the wear resistance of melamine-impregnated paper, wear-resistant powder coating treatment is required on its surface.

[0003] Existing abrasion-resistant powder coating equipment for melamine-impregnated paper surfaces has revealed many shortcomings in practical applications. Traditional nozzles are usually fixedly installed, so they can only spray powder at a fixed angle. It is difficult to flexibly adjust the spraying angle according to the actual conditions of the paper, such as different widths, thicknesses, and surface shapes, resulting in uneven powder coating, with some areas being sprayed with too much or too little powder. This not only affects product quality but also wastes powder materials. Therefore, a new abrasion-resistant powder coating equipment for melamine-impregnated paper surfaces is proposed to solve the above problems. Utility Model Content

A support plate 41 is provided for support. A set of multiple turntables 42 are rotatably connected to the middle part of the support plate 41, which drives the connecting rod 43 and the nozzle 44 to rotate and adjust the angle of the nozzle 44. The connecting rod 43 that drives the nozzle 44 to rotate is fixedly connected to the rear surface of the middle part of the multiple turntables 42. The nozzle 44 that can spray powder coating to process the surface of melamine impregnated paper is fixedly connected to the rear surface of the multiple nozzles 44 near the upper end. The fixed pipe 45 that supports the nozzle 44 and provides powder coating is rotatably connected to the rear surface of the multiple fixed pipes 45. The sealing ring that increases the sealing performance is fixedly connected to the front surface of the multiple fixed pipes 45. The multiple sealing rings are rotatably connected to the rear part of the nozzle 44 near the top. The multiple fixed pipes 45 are fixedly connected to the bottom end of the conveying pipe 22. The fixed pipe 45 is L-shaped. The toggle block that drives the turntable 42 to rotate is fixedly connected to the front surface of the turntable 42.

[0031] Reference Figure 1 , Figure 3 and Figure 4 The adjustment mechanism also includes a limiting component 5, which is used to simultaneously limit multiple sets of turntables 42 and nozzles 44. The limiting component 5 includes a guide block 51 set above the support plate 41. The bottom end of the guide block 51 is fixedly connected to multiple sets of sliding rods 52 that drive the limiting block 55 to move. The support plate 41 has multiple sets of sliding grooves 56 provided for the movement of the limiting block 55 near the top of the multiple sets of turntables 42. The bottom end of the multiple sets of sliding rods 52 is fixedly connected to the limiting block 55 that slides on the inner wall of the multiple sets of sliding grooves 56. The multiple sets of limiting blocks 55 are respectively engaged with the outer wall of the top of the multiple sets of turntables 42. The top of the support plate 41 is fixedly connected to a positioning rod 53 that passes through and slides through the guide block 51. The top of the support plate 41 is rotatably connected to a threaded rod 54 that passes through and is threadedly connected to the guide block 51 near the right side of the positioning rod 53. The limiting block 55 is U-shaped and the bottom end is arc-shaped and fits against the outer wall of the top of the turntable 42 to limit the turntable 42.

[0032] Reference Figure 1 and Figure 2 A blocking component 3 is provided on the left side of the guide rail 21. The blocking component 3 includes a baffle 31 that blocks powder from splashing onto the guide rail 21. The baffle 31 is fixedly connected to the bottom left side of the support frame 23. The bottom of the support frame 23 is slidably connected to the outer wall of the guide rail 21. The right side of the baffle 31 has slots 34 on both the front and rear outer sides near the support frame 23. The inner walls of the two sets of slots 34 have slots 36 on both the front and rear sides. The inner walls of the two sets of slots 34 on the right side of the baffle 31 are engaged with blocks 33. The front and rear surfaces of the two sets of blocks 33 are fixedly connected with springs. After the elastic piece 35 and the locking block 33 are inserted into the first locking slot 34, the elastic piece 35 is inserted into the second locking slot 36 to limit the installation of the brush 32. At this time, the bristles at the bottom of the brush 32 are in contact with the guide rail 21. When the support frame 23 moves, it can drive the brush 32 to move synchronously and clean the powder on the guide rail 21. Multiple sets of elastic pieces 35 are respectively locked into the inner wall of the corresponding second locking slot 36. The right side of the two sets of locking blocks 33 are respectively fixedly connected to the brush 32, and the bristles at the bottom of the two sets of brushes 32 are in contact with the outer wall of the guide rail 21.

[0033] Working principle: When in use, place the melamine-impregnated paper on the operating table 2, connect the external air pump and the delivery pipe 22 to ensure that the powder coating is supplied normally.

[0034] When the angle of the nozzle 44 needs to be adjusted according to the width of the paper, the limit block 55 is moved by rotating the threaded rod 54 to release the limit of the turntable 42. Then, the toggle block on the front surface of the turntable 42 is moved to rotate the turntable 42. When the turntable 42 rotates, the connecting rod 43 fixedly connected to it will drive the nozzle 44 to rotate around the fixed tube 45, thereby changing the spray angle of the nozzle 44. Since the fixed tube 45 is L-shaped, it not only supports the nozzle 44, but also ensures the stable transmission of powder coating. The sealing ring on the front surface of the fixed tube 45 is rotatably connected to the nozzle 44 near the top rear part to prevent powder coating leakage.

[0035] After adjusting the nozzle 44 angle, it needs to be limited. Rotate the threaded rod 54 in the opposite direction. Because the threaded rod 54 is threadedly connected to the guide block 51, and the guide block 51 is slidably connected to the positioning rod 53, when the threaded rod 54 rotates, the guide block 51 will move downward along the positioning rod 53. The slide rod 52 at the bottom of the guide block 51 will drive the limiting block 55 to slide in the slide groove 56. When the limiting block 55 is engaged with the outer wall of the top of the turntable 42, the turntable 42 will be squeezed and limited, thus limiting the turntable 42 and the nozzle 44 and ensuring that the nozzle 44 angle is stable during the powder spraying process.

[0036] At this time, the external air pump is started. The air pump transmits the powder coating through the delivery pipe 22 to the fixed pipe 45, and then sprays it out from the nozzle 44 to perform powder coating on the surface of melamine-impregnated paper. At the same time, the support frame 23 slides on the guide rail 21, driving the support block 24, nozzle 44 and other components to move, so as to realize the powder coating operation on different positions of the paper.

[0037] During the movement of the support frame 23, the baffle 31 fixed on its bottom left side will move synchronously. A brush 32 is fixed on the locking block 33 on the right side of the baffle 31. The bristles at the bottom of the brush 32 contact the outer wall of the guide rail 21. The locking block 33 is installed and limited by the elastic sheet 35 cooperating with the locking groove 34 and locking groove 36 on the baffle 31. When the support frame 23 moves, the brush 32 will clean the powder that may splash on the guide rail 21 to ensure the cleanliness of the guide rail 21 and allow the support frame 23 to move smoothly. After the powder spraying work is completed, the external air pump is turned off and the powder coating supply is stopped, and the work is completed.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
