[0021] Please see Figures 1-5 A spray head for a hardware spraying machine with an anti-drip structure includes a spray head body 1. A fixed base 2 is detachably connected to the outside of the spray head body 1. An electric cylinder 3 is fixedly connected to the fixed base 2. A lifting seat 4 is fixedly connected to the top of the electric cylinder 3. Multiple vertical rods 23 are fixedly connected to the top of the fixed base 2. The multiple vertical rods 23 are slidably engaged with the lifting seat 4 to ensure stable up and down movement of the lifting seat 4. A motor 5 is fixedly connected to the top of the lifting seat 4. A rotating shaft 6 is fixedly connected to the output end of the motor 5. The rotating shaft 6 is slidably engaged with the fixed base 2. A receiving seat 7 is detachably connected to the bottom of the rotating shaft 6. A receiving groove 8 is provided on the receiving seat 7. A plug needle 9 adapted to the spray head body 1 is fixedly connected inside the receiving groove 8. A first limiting plate 21 is fixedly connected to the side end of the rotating shaft 6. A second limiting plate 22 is fixedly connected to the bottom end of the fixed base 2 to limit the rotation shaft 6.
[0022] Specifically, after the spraying is completed, the motor 5 drives the rotating shaft 6 and the receiving seat 7 to rotate, rotating the receiving groove 8 to the bottom of the nozzle body 1. The paint dripping from the nozzle will drip into the inside of the receiving groove 8. Then, the electric cylinder 3 pushes the lifting seat 4, the rotating shaft 6 and the receiving seat 7 to move upward, so that the plugging needle 9 is inserted into the inside of the nozzle body 1. The plugging needle 9 seals the nozzle body 1 to prevent paint from dripping down from the inside of the nozzle body 1 and to prevent the paint on the nozzle body 1 from dripping onto the surface of the hardware and damaging the paint layer sprayed on the surface of the hardware.
[0023] Please see Figure 1 and Figure 3 The fixed base 2 is provided with a through groove 10, and the nozzle body 1 is located inside the through groove 10. The side end of the through groove 10 is provided with a sliding groove 11. A bidirectional screw 12 is rotatably connected inside the sliding groove 11. Two sliding seats 13 are symmetrically threaded on the outside of the bidirectional screw 12. Both sliding seats 13 are slidably engaged with the sliding groove 11. A clamping seat 24 is fixedly connected to the side end of each of the two sliding seats 13. An arc-shaped clamping groove 14 on the clamping seat 24 is adapted to the outer wall of the nozzle body 1, which facilitates the assembly and disassembly of the fixed base 2. An anti-slip pad 15 is fixedly connected inside the arc-shaped clamping groove 14 to increase the friction of the surface of the arc-shaped clamping groove 14 and improve the stability of clamping and fixing the nozzle body 1. A handle 16 is rotatably connected to the fixed base 2. The handle 16 is fixedly connected to the side end of the bidirectional screw 12, which facilitates the rotation of the bidirectional screw 12.
[0024] Specifically, the fixing seat 2 is placed on the outside of the nozzle body 1, and then the bidirectional screw 12 is rotated clockwise. The clockwise rotation of the bidirectional screw 12 causes the two slides 13 to move towards the center. The two slides 13 drive the two clamping seats 24 to move, so that the two clamping seats 24 clamp and fix the nozzle body 1, thereby fixing the fixing seat 2 on the nozzle. The bidirectional screw 12 is rotated counterclockwise to separate the two clamping seats 24 from the nozzle body 1, so that the fixing seat 2 can be disassembled and thus facilitated to disassemble and assemble the fixing seat 2.
[0025] Please see Figure 1 , Figure 2 and Figure 5 The top of the receiving base 7 is fixedly connected to a sleeve 17, and the bottom end of the rotating shaft 6 is inserted into the inside of the sleeve 17. The external thread of the sleeve 17 is connected to a fixing screw 18 that matches the rotating shaft 6, which facilitates the disassembly and replacement of the receiving base 7. The top of the sleeve 17 is provided with a positioning groove 19, and the external part of the rotating shaft 6 is fixedly connected to a positioning block 20 that matches the positioning groove 19, which plays a positioning role for the sleeve 17.
[0026] Specifically, the sleeve 17 is placed over the outside of the rotating shaft 6, and the positioning block 20 is inserted into the inside of the positioning groove 19. Then, the fixing screw 18 is tightened so that the side end of the fixing screw 18 contacts the outer wall of the rotating shaft 6, which facilitates the fixing of the receiving seat 7 on the rotating shaft 6. The fixing screw 18 is loosened so that the sleeve 17 can be pulled off the rotating shaft 6, which facilitates the disassembly and replacement of the receiving seat 7.
[0027] In summary, when using the overall equipment: The motor 5 and electric cylinder 3 are electrically connected to an external power source and a matching control switch. After the metal parts are sprayed, the motor 5 is controlled to work by the control switch. The motor 5 drives the rotating shaft 6 and the receiving seat 7 to rotate, so that the receiving seat 7 rotates to the bottom of the nozzle body 1. When the first limit plate 21 and the second limit plate 22 come into contact, the blocking needle 9 is located directly below the nozzle body 1. Then the motor 5 is stopped. Then the electric cylinder 3 drives the lifting seat 4, the rotating shaft 6 and the receiving seat 7 to move upward, so that the blocking needle 9 is inserted into the interior of the nozzle body 1, blocking the nozzle of the nozzle body 1 and preventing paint dripping.
