Technical Field
[0001] This utility model relates to the technical field of spraying paint on both ends of a saw blade, and in particular to a spraying device for spraying paint on both ends of a saw blade. Background Technology
[0002] The structure of saw blades produced in a certain workshop is as follows: Figures 1-2 As shown, it includes multiple tooth seats 2 evenly fixed on the outer edge of the saw blade 1 along its circumference, and a central hole 3 is opened in the center of the saw blade 1. In order to improve the wear resistance of the saw blade, the process requires that a layer of paint be sprayed on both ends of a batch of saw blades 1. After the paint is sprayed, the worker puts the saw blade 1 into an oven to dry the paint adhering to both ends of the saw blade 1, so that the paint is firmly adhered to the saw blade 1.
[0003] The workshop uses, for example Figure 3 The paint sprayer shown is used to spray paint on both ends of the saw blade 1. The paint sprayer includes a protective cover 4 and a drive motor 5 fixedly installed at the bottom of the protective cover 4. An opening is provided on the front side of the protective cover 4. A protective door 6 is hinged to the left side wall of the opening via a hinge seat. The output shaft of the drive motor 5 extends into the protective cover 4, and a fixed seat 7 is fixedly provided on the extended end. A positioning table 8 is connected to the top surface of the fixed seat 7. The diameter of the positioning table 8 is equal to the diameter of the central hole 3 of the saw blade 1. Multiple support columns 9 supported on the ground are fixed on the bottom surface of the protective cover 4. A pipe 10 is fixed inside the right side wall of the protective cover 4. A pressure pump is connected to the right end of the pipe 10. The left end of the pipe 10 extends into the protective cover 4. Multiple atomizing ball heads 11 are fixed on the bottom surface of the extended end of the pipe 10 along its length. The method by which workers use the spray painting machine to spray a layer of paint on both ends of a batch of saw blades 1: S1, the worker takes out a... Figures 1-2 The saw blade 1 to be painted is inserted into the protective cover 4 through the opening, and then the center hole 3 of the saw blade 1 is fitted onto the positioning table 8 from top to bottom. The saw blade 1 is then supported on the top surface of the fixing base 7, thus completing the installation of the saw blade 1. Figure 4 As shown; S2. The worker pushes the protective door 6 forward, and the protective door 6 rotates forward around the hinge seat so that the protective door 6 presses against the front end face of the protective cover 4, thereby closing the opening of the protective cover 4 through the protective door 6; S4. Turn on the drive motor 5. The output shaft of the drive motor 5 drives the fixed seat 7 to rotate. The fixed seat 7 drives the positioning table 8 to rotate. The positioning table 8 drives the saw blade 1 to rotate. The saw blade 1 rotates relative to the stationary pipe 10 on the horizontal plane. S5. The worker turns on the pressure pump, which draws the paint out of the paint tank. Under pump pressure, the paint enters pipe 10. The direction of paint entry is as follows: Figure 4 As shown by the middle arrow, the paint is then sprayed from the atomizing hole of the atomizing ball head 11. The sprayed paint adheres to the top surface of the saw blade 1, thus achieving the spraying of paint onto the rotating saw blade 1. After the saw blade 1 has rotated for a period of time, the worker turns off the drive motor 5, thus achieving the spraying of a layer of paint on one end face of the saw blade 1. S6. The worker opens the protective door 6 so that the protective door 6 moves away from the protective cover 4, and then removes the saw blade 1 from the positioning table 8. After removing it, the worker rotates the saw blade 1 180°, and then the worker puts the saw blade 1 back on the outside of the positioning table 8, thereby realizing the reinstallation of the saw blade 1. S7. The worker repeats steps S2 to S5 once, thereby spraying a layer of paint on the other end of the saw blade 1, and finally achieving that the paint is sprayed on both ends of the first saw blade 1. S8. Workers repeat steps S1 to S7 multiple times to coat both ends of a batch of saw blades 1 with a layer of paint.
[0004] However, although this paint spraying machine can coat both ends of a batch of saw blades 1 with paint, workers still reported the following technical defects during actual use: I. In steps S5 to S6, after the paint is sprayed on one end of the saw blade 1, the worker needs to manually rotate the saw blade 1 180° before the paint can be sprayed on the other end of the saw blade 1. In other words, a total of two spraying processes are required to spray a layer of paint on both ends of the saw blade 1. This not only increases the workload of the workers, but also reduces the efficiency of spraying paint on the saw blade 1.
[0005] II. The diameter of this saw blade 1 is relatively large, while the space of the protective cover 4 is limited. Therefore, only one saw blade 1 can be placed inside the protective cover 4. In other words, only one saw blade 1 can be painted at a time. However, the number of saw blades to be painted each day is as high as 100, which means that it takes a long time to paint all 100 saw blades 1, thus further reducing the efficiency of painting the saw blades 1.
[0006] Therefore, there is an urgent need for a spraying device that can greatly reduce the workload of workers and greatly improve the efficiency of spraying saw blades. Utility Model Content

[0016] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description: like Figures 5-9 As shown, a spraying device for spraying paint on both ends of a saw blade includes a protective housing 12. The right end of the protective housing 12 has an opening. A horizontal cylinder 13 and a vertical cylinder 14 are fixed on the left end of the protective housing 12. A movable plate 15 is fixed on the working end of the piston rod of the horizontal cylinder 13. A rod 16 that extends to the right and penetrates through the support column 9 of the protective housing 12 is also fixed on the right end of the movable plate 15.

[0017] A servo motor 18 is fixedly mounted on the right end face of the movable plate 15. A rotating shaft 19 is connected to the output shaft of the servo motor 18. The rotating shaft 19 extends to the right through the left side wall of the protective shell 12 and the opening of the protective shell 12 and extends outside the protective shell 12. A fixing plate 20 is fixedly mounted on the extended end of the rotating shaft 19. A first support rod 21 is fixedly mounted on the right end face of the fixing plate 20. Two annular grooves 22 are opened on the cylindrical surface of the first support rod 21. An adjusting plate 23 is also provided on the fixing plate 20, located directly below the first support rod 21. A vertically arranged waist-shaped hole 24 is opened in the adjusting plate 23. The adjusting plate 23 is threadedly connected to the fixing plate 20 through the waist-shaped hole 24 by a locking screw 25, so as to fix the adjusting plate 23 on the fixing plate 20. A second support rod 26 is fixedly mounted on the right end face of the adjusting plate 23. A dynamic sealing element I is provided between the rotating shaft 19 and the left side wall of the protective shell 12.
[0018] The piston rod of the vertical cylinder 14 extends upward, and a connecting plate 27 is fixed on the extended end. A painting assembly is connected to the connecting plate 27. The painting assembly includes a vertical main pipe 28 fixed on the right end of the connecting plate 27. The top port of the vertical main pipe 28 is connected to the working port of the pressure pump via a hose 29. The vertical main pipe 28 penetrates the top wall of the protective housing 12 and extends into the protective housing 12. A horizontal main pipe 30 with both ends closed is fixed on the extended end of the vertical main pipe 28. The horizontal main pipe 30 is connected to the vertical main pipe 28. Four branch pipes 31 are fixed on the bottom surface of the horizontal main pipe 30 at intervals along its length. Multiple atomizing ball heads 11 are fixed on the inner cylindrical surfaces of two opposing branch pipes 31.
[0019] A dynamic seal II is provided between the vertical main pipe 28 and the top wall of the protective housing 12. The spraying device also includes a controller, which is electrically connected to the horizontal cylinder 13, the vertical cylinder 14 and the servo motor 18 via signal lines.

[0020] The method by which workers use this spray painting device to spray a layer of paint on both ends of a batch of saw blades 1: S1, the worker takes out a... Figures 1-2 The saw blade 1 shown is fitted with its center hole 3 onto the outside of the first support rod 21 and the second support rod 26. Then, the saw blade 1 is pushed to the left. When the worker observes that the left end face of the saw blade 1 is flush with the right end face of the left annular groove 22 of the first support rod 21, the worker stops pushing the saw blade 1, thus achieving the positioning of the first saw blade 1. Figure 10 As shown; S2. The worker removes the second saw blade 1, places the center hole 3 of saw blade 1 over the outside of the first support rod 21 and the second support rod 26, and then pushes the saw blade 1 to the left. When the left end face of the saw blade 1 is observed to be flush with the right end face of the right annular groove 22 of the first support rod 21, the worker stops pushing the saw blade 1, thus achieving the positioning of the second saw blade 1. Figure 11 As shown; S3. Fix the two saw blades 1. The specific operation steps are as follows: S31. The worker loosens the locking screw 25, and the locking screw 25 no longer fixes the adjusting plate 23; S32. The worker presses down on the adjusting plate 23, which causes the second support rod 26 to move downwards. The direction of movement of the second support rod 26 is as follows: Figure 12 As shown by the middle arrow, after the second support rod 26 presses against the bottom wall of the center hole 3 of the two saw blades 1, the worker tightens the locking screw 25 again. The locking screw 25 then fixes the adjusting plate 23 onto the fixing plate 20, thus using the first support rod 21 and the second support rod 26 to fix the two saw blades 1 in place. Figure 12 As shown; S4. The piston rod of the horizontal cylinder 13 extends to the left, which drives the moving plate 15 to move to the left. The moving plate 15 drives the rod 16 and the servo motor 18 to move to the left synchronously. The rod 16 drives the protective cover 17 to move to the left, and the protective cover 17 moves towards the protective shell 12. At the same time, the servo motor 18 drives the rotating shaft 19 and the fixed plate 20 to move to the left synchronously. The fixed plate 20 drives the first support rod 21 and the second support rod 26 to move to the left synchronously, which in turn drives the two fixed saw blades 1 to move to the left synchronously. When the piston rod of the horizontal cylinder 13 is fully extended, the protective cover 17 abuts against the right end face of the protective housing 12, as follows. Figure 13 As shown, the opening of the protective housing 12 is closed, and at the same time, the two saw blades 1 enter the protective housing 12 and are positioned at the painting station of the painting assembly. S5. Control the piston rod of the vertical cylinder 14 to retract downwards. The piston rod drives the connecting plate 27 to move downwards. The connecting plate 27 drives the vertical main pipe 28 to move downwards. The vertical main pipe 28 drives the horizontal main pipe 30 and the four branch pipes 31 to move downwards. The four branch pipes 31 then drive the atomizing ball head 11 to move downwards synchronously. When the piston rod perpendicular to the hydraulic cylinder 14 is fully retracted, the two branch pipes 31 on the left are respectively positioned on both sides of the saw blade 1 on the left, as shown in the image. Figure 14 As shown, the two branch pipes 31 on the right side are located on both sides of the saw blade 1 on the right side. S6. Start the servo motor 18. The servo motor 18 drives the rotating shaft 19 to rotate. The rotation direction of the rotating shaft 19 is as follows: Figure 15 As shown by the solid arrow, the rotating shaft 19 drives the fixed plate 20 to rotate, and the fixed plate 20 drives the first support rod 21 and the second support rod 26 to rotate around the axis of the rotating shaft 19, thereby driving the two saw blades 1 to rotate synchronously around the axis of the rotating shaft 19. S7. The worker turns on the pressure pump, which draws the paint out of the paint tank. Under pump pressure, the paint flows sequentially through hose 29, vertical main pipe 28, horizontal main pipe 30, and branch pipe 31. The direction of paint entry is as follows: Figure 15 As shown by the hollow arrow, the paint is finally sprayed out from the atomizing hole of the atomizing ball head 11. The sprayed paint adheres to the left and right end faces of the saw blade 1, thus realizing the gradual painting of the saw blade 1 in the rotating state. After the painting has been done for a period of time, the control pressure pump and servo motor 18 are turned off, thus finally achieving the spraying of a layer of paint on the left and right end faces of both saw blades 1. As can be seen from steps S5-S7, the worker only needs to start the servo motor 18 to make both saw blades 1 rotate around the axis of the rotating shaft 19, and then start the pressure pump to spray a layer of paint onto the left and right end faces of both saw blades 1. Therefore, this spraying device is superior to... Figures 3-4 The painting method shown eliminates the need to paint the two ends of the saw blade 1 separately in two steps. Instead, it allows for simultaneous painting of both ends of the saw blade 1, which not only reduces the workload of workers but also greatly improves the efficiency of painting the saw blade 1.
[0021] Furthermore, this spraying device can spray paint on two saw blades 1 at once, compared to... Figures 3-4The painting method shown eliminates the need to paint each saw blade 1 one by one, thus enabling the painting of all 100 saw blades 1 in the workshop in a short time, thereby further improving the efficiency of painting the saw blades 1.
[0022] S8. The two saw blades 1 that are painted are removed. The specific operating steps are as follows: S81, the piston rod of the horizontal cylinder 13 retracts to the right, the piston rod drives the moving plate 15 to move to the right, the moving plate 15 drives the rod 16 and the servo motor 18 to move to the right synchronously, the rod 16 drives the protective cover plate 17 to move to the right, and the protective cover plate 17 moves away from the protective shell 12; at the same time, the servo motor 18 drives the rotating shaft 19 and the fixed plate 20 to move to the right synchronously, the fixed plate 20 drives the first support rod 21 and the second support rod 26 to move to the right synchronously, and then drives the two saw blades 1 sprayed with paint to move to the right; When the piston rod of the horizontal cylinder 13 is fully retracted, the two saw blades 1, which are painted, move to the outside of the protective housing 12. S82. The worker loosens the locking screw 25, and then lifts the adjusting plate 23 upward. The adjusting plate 23 drives the second support rod 26 to move upward, and the second support rod 26 no longer fixes the saw blade 1. Then the worker removes the two saw blades 1 that are sprayed with paint. S9. Workers repeat steps S1 to S8 multiple times to coat both ends of a batch of saw blades 1 with a layer of paint.
[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
