Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-3 As shown, a refrigeration aluminum pipe rotary zinc spraying device includes a workbench 1. A support plate 2 is installed on the top side of the workbench 1. A dust suction hood 3 is installed on the top side of the support plate 2. A plurality of dust suction holes 4 are opened inside the bottom side of the dust suction hood 3. One side of the dust suction hood 3 is connected with a conveying pipe 5. A dust collection box 6 is assembled at the edge of the top side of the workbench 1. One end of the conveying pipe 5 is connected and arranged with the dust collection box 6. Sleeves 7 are installed at the four corner positions of the bottom side of the dust collection box 6. Springs 8 are fixedly connected inside the sleeves 7. One end of each spring 8 is connected with a movable rod 9. One end of each movable rod 9 slides and extends to the top side of the sleeve 7 and is fixedly connected with a filter plate 10. An L-shaped plate 11 is installed on one side of the dust collection box 6. A negative pressure motor 12 is installed inside the L-shaped plate 11. The output end of the negative pressure motor 12 slides and extends into the dust collection box 6 and three fan blades 13 are equidistantly installed. The middle end of the output shaft of the negative pressure motor 12 is installed with a driving gear 14. A rotating shaft 15 is rotatably installed through the inside of the dust collection box 6. A driven gear 16 is installed on the outer wall of one end of the rotating shaft 15, and the driving gear 14 and the driven gear 16 are meshed with each other. An eccentric wheel 17 is installed on the outer wall of the middle end of the rotating shaft 15. The eccentric wheel 17 will contact the filter plate 10 during operation. Air outlet holes 18 are opened on one side of the dust collection box 6;

[0024] One side of the workbench 1 is equipped with a control panel 38, which is used for operating and controlling the electrical components inside the device. During operation, in practical applications, when spraying zinc on the aluminum tube, it is necessary to collect dust, which will cause the filter plate 10 in the dust collection box 6 to be blocked, reducing the filtration efficiency and affecting the dust collection effect. When spraying zinc, the negative pressure motor 12 is started, and the negative pressure motor 12 drives the three fan blades 13 to rotate, generating negative pressure in the dust collection box 6. The zinc dust generated during the spraying process is sucked into the dust suction hood 3 through the dust suction hole 4, then enters the dust collection box 6 through the conveying pipe 5 and lands on the filter plate 10. The zinc dust is intercepted, realizing the centralized collection of dust. At the same time, the rotation of the output shaft of the negative pressure motor 12 will drive the rotation of the driving gear 14. The driving gear 14 meshes with the driven gear 16 to drive the rotation of the rotating shaft 15, and the eccentric wheel 17 rotates accordingly. When the eccentric wheel 17 contacts the filter plate 10, it will push the filter plate 10 upward, stretching the spring 8. When the eccentric wheel 17 rotates past, the spring 8 rebounds to make the movable rod 9 drive the filter plate 10 to reset, so that the filter plate 10 will continuously vibrate up and down, preventing dust from blocking the filter plate 10 and ensuring the filtering effect. The filtered air is discharged from the air outlet 18.

[0025] Please refer to Figures 1-5 As shown, a rotating motor 19 is installed on one side of the support plate 2. The output end of the rotating motor 19 is equipped with a rotating shaft 20. One end of the rotating shaft 20 is connected with a fixing component. The fixing component includes a limiting plate 21. A threaded cylinder 22 is installed on one side of the limiting plate 21. An outer cylinder 23 is slidably installed on the outer wall of the threaded cylinder 22. A servo motor 24 is installed on one side of the outer cylinder 23. The output end of the servo motor 24 is equipped with a threaded rod 25. One end of the threaded rod 25 penetrates and extends into the interior of the threaded cylinder 22 and is threadedly engaged therewith. Four sliding grooves 26 are equidistantly opened inside the limiting plate 21. Sliding blocks 27 are slidably installed inside the sliding grooves 26. Arc-shaped clamping plates 28 are installed on one side of each of the sliding blocks 27. Two mounting seats 29 are installed at the four corners of the inner wall of the arc-shaped clamping plate 28 and the outer wall of the outer cylinder 23. Connecting rods 30 are installed between the mounting seats 29 by means of pins. During operation, during the zinc spraying process, there will be high-speed ejected zinc material, and the aluminum tube is easily shaken or even dropped due to the impact force, resulting in uneven zinc spraying and affecting the zinc spraying quality. The aluminum tube is sleeved on the arc-shaped clamping plate 28. The servo motor 24 is started to drive the rotation of the threaded rod 25, pushing the outer cylinder 23 to slide on the threaded cylinder 22. The movement of the outer cylinder 23 is connected to the mounting seat 29 through the connecting rod 30, which will drive the arc-shaped clamping plate 28 to move along the sliding groove 26, and will make the arc-shaped clamping plate 28 move away from the center of the circle through the action of the connecting rod 30, so as to support and fix the aluminum tube from the inside, realizing the inner support and fixation of the aluminum tube, and thus realizing the fixation of aluminum tubes of different sizes, ensuring the stability of the aluminum tube during the rotary zinc spraying process.

[0026] Please refer to Figure 1 、 2 As shown in FIGS. 5, two support columns 31 are symmetrically installed at the top side edge of the workbench 1. The top end of the support column 31 is installed with a straight pipe 32. Four nozzles 33 are equidistantly installed on the outer wall of the straight pipe 32. A feed pipe 34 is connected to the outer wall of the straight pipe 32;

[0027] One end of the straight pipe 32 is threadedly installed with a screw rod 35. One end of the screw rod 35 is installed with a handle 36. The other end of the screw rod 35 is installed with a piston plate 37, and the outer diameter of the piston plate 37 is equal to the inner diameter of the straight pipe 32. During operation, in the process of processing refrigeration aluminum pipes, in order to improve the corrosion resistance of the aluminum pipes in various environments and extend their service life, a zinc spraying operation is required. By rotating the handle 36 to drive the screw rod 35 to rotate, the rotation of the screw rod 35 will cause it to move along the axial direction of the straight pipe 32, thereby driving the piston plate 37 to move within the straight pipe 32, so as to adjust and control the operation of the nozzle 33, and thus realize the adjustment of the spraying range of the nozzle 33, avoiding unnecessary waste of zinc powder. During the zinc spraying operation, the zinc material is transported into the straight pipe 32 through the feed pipe 34, and then evenly sprayed from the nozzle 33 onto the surface of the aluminum pipe, enhancing the corrosion resistance and service life of the aluminum pipe.

[0028] Working principle: The aluminum pipe is sleeved on the arc-shaped clamping plate 28. The servo motor 24 is started to drive the threaded rod 25 to rotate, which will push the outer cylinder 23 to slide on the threaded cylinder 22. The movement of the outer cylinder 23 is connected to the mounting seat 29 through the connecting rod 30, which will drive the arc-shaped clamping plate 28 to move along the chute 26, and will make the arc-shaped clamping plate 28 move away from the center of the circle through the action of the connecting rod 30, so as to support and fix the aluminum pipe from the inside, realizing the internal support and fixation of the aluminum pipe, and thus realizing the fixation of aluminum pipes of different sizes, ensuring that the aluminum pipe remains stable during the rotary zinc spraying process;

[0029] By rotating the handle 36 to drive the screw rod 35 to rotate, the rotation of the screw rod 35 will cause it to move along the axial direction of the straight pipe 32, thereby driving the piston plate 37 to move within the straight pipe 32, so as to adjust and control the operation of the nozzle 33, and thus realize the adjustment of the spraying range of the nozzle 33, avoiding unnecessary waste of zinc powder. During the zinc spraying operation, the zinc material is transported into the straight pipe 32 through the feed pipe 34, and then evenly sprayed from the nozzle 33 onto the surface of the aluminum pipe, enhancing the corrosion resistance and service life of the aluminum pipe;

[0030] When performing the zinc spraying operation, start the negative pressure motor 12. The negative pressure motor 12 drives the three fan blades 13 to rotate, generating negative pressure in the dust collection box 6. The zinc dust generated during the zinc spraying process is sucked into the dust suction hood 3 through the dust suction holes 4, and then enters the dust collection box 6 through the conveying pipe 5 and lands on the filter plate 10. The zinc dust is intercepted, realizing the centralized collection of dust. At the same time, the rotation of the output shaft of the negative pressure motor 12 will drive the rotation of the driving gear 14. The driving gear 14 meshes with the driven gear 16 for transmission, thereby driving the rotation of the rotating shaft 15, and the eccentric wheel 17 rotates accordingly. When the eccentric wheel 17 contacts the filter plate 10, it will push the filter plate 10 upward, stretching the spring 8. When the eccentric wheel 17 rotates past, the spring 8 rebounds, causing the movable rod 9 to drive the filter plate 10 to reset, so that the filter plate 10 will continuously vibrate up and down, preventing dust from clogging the filter plate 10 and ensuring the filtering effect. The air after filtration is discharged from the air outlet 18.
