By setting the synchronous structure and the spacing adjustment mechanism, the moving stroke of the nozzle 7 after clamping the workpiece is adapted to the length of the workpiece, thereby reducing paint waste and improving processing efficiency.

[0026] like Figure 1-5 As shown, an electric push rod 19 is fixedly installed on the upper end of the first installation box 3, and the output end of the electric push rod 19 is fixedly connected to the installation plate 5, and the auxiliary clamping block 29 is rotatably connected to the outer end surface of the installation plate 5.

[0029] like Figure 1-5 As shown, the synchronization structure includes a connecting rod 6 fixedly connected to both ends of the adjustment block 12, and the lower end of the connecting rod 6 is fixedly connected to the mounting plate 5. By setting the synchronization structure, the mounting plate 5 drives the adjustment block 12 to move when it moves, so that the adjustment block 12 and the mounting plate 5 are in the same vertical plane, and the position of the adjustment block 12 is automatically adjusted when the workpiece is clamped, so that the moving stroke of the nozzle 7 matches the size of the workpiece, thereby improving the user's convenience and improving the work efficiency during spraying.

[0030] like Figure 1-5 As shown, a mounting block 9 is fixedly connected to the top of the mounting shell 1, a paint tank 8 is installed in the mounting block 9, a connecting hose 17 is provided on the nozzle 7, the nozzle 7 and the paint tank 8 are connected via the connecting hose 17, the mounting block 9 is provided to store the paint, and the connecting hose 17 is used to supply the paint to the nozzle 7.

[0031] like Figure 1-5 As shown, a guide groove 15 is provided on the adjusting rod 11, and a guide block 16 is fixedly connected to the upper end of the connecting block 14 corresponding to the guide groove 15. The guide block 16 is slidably connected in the guide groove 15. By arranging the connecting block 14 to cooperate with the guide groove 15, the function of limiting the horizontal movement of the connecting block 14 is realized, thereby improving the stability of the connecting block 14 during horizontal movement.

[0032] like Figure 1-5 As shown, both side ends of the first drive motor 20 and the second drive motor 21 are fixedly connected with mounting brackets 30, and the first drive motor 20 and the second drive motor 21 are fixedly installed in the second installation box 4 through the mounting brackets 30. The first drive motor 20 and the second drive motor 21 are clamped by setting the mounting brackets 30 to improve the installation stability of the first drive motor 20 and the second drive motor 21 in the second installation box 4.

[0033] Working principle: When clamping a workpiece, one end of the workpiece is pressed against the main clamping block 28, and the mounting piece 5 is moved by the electric push rod 19, and the mounting piece 5 drives the auxiliary clamping block 29 to squeeze the other end of the workpiece, thereby clamping the workpiece. When the mounting piece 5 moves, it drives the adjustment block 12 to move, so that the adjustment block 12 and the mounting piece 5 are in the same vertical horizontal plane;

[0034] After the workpiece is clamped between the main clamping block 28 and the auxiliary clamping block 29, the first drive motor 20, the second drive motor 21 and the nozzle 7 are started. The main clamping block 28 is driven to rotate by the second drive motor 21, and the auxiliary clamping block 29 is rotated on the mounting plate 5 to realize the function of driving the workpiece to rotate, so that the coating sprayed by the nozzle 7 can be more evenly distributed on the workpiece. The active bevel gear 23 is driven to rotate by the first drive motor 20, and the active bevel gear 23 drives two driven bevel gears 24 to rotate. When one of the driven bevel gears 24 rotates, the driving gear sleeve 25 is driven to rotate synchronously through the rotating block 26. The driving gear sleeve 25 cooperates with the driven gear sleeve 27 to drive the threaded rod 10 to rotate. When the threaded rod 10 rotates, the connecting block 14 is driven to move. The movement of the connecting block 14 drives the nozzle 7 to move at the upper end of the workpiece. For example, when the connecting block 14 moves toward one end of the adjusting block 12, when the connecting block 14 contacts the spring 13, the spring 13 is limited by the adjusting block 12 and cannot move. , so that the connecting block 14 squeezes the spring 13 to deform the spring 13, and when the spring 13 is deformed, the pushing connecting block 14 is moved in the opposite direction, so that the threaded rod 10 slides in the opposite direction in the mounting housing 1. After the threaded rod 10 slides, the driven gear sleeve 27 meshes with the other driving gear sleeve 25. Since the rotation directions of the two driven bevel gears 24 are opposite, the driven gear sleeve 27 meshes with the other driving gear sleeve 25 to rotate in the opposite direction, thereby driving the threaded rod 10 to rotate in the opposite direction, so that the threaded rod 10 drives the spray head 7 to move in the opposite direction through the connecting block 14, thereby realizing the function of making the spray head 7 reciprocate on the threaded rod 10, so that the paint tank 8 of the mounting housing 1 sprays the workpiece more evenly, and when clamping, the position of the adjusting block 12 and the mounting piece 5 will be in the same vertical horizontal plane, so that the position of the adjusting block 12 is automatically adjusted when the workpiece is clamped, so that the moving stroke of the spray head 7 matches the size of the workpiece, improves the user's convenience, and improves the work efficiency during spraying.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
