Every two abutting assemblies are installed on both sides of the top of a mounting seat 12.

[0041] like Figure 1-Figure 12 As shown, each swing assembly includes a moving block 36, an arc-shaped guide rod 37, a moving rod 41, a strip groove 42, an insertion rod 43, a hinge rod 44 and two fixing plates 38; The two fixed plates 38 are symmetrically fixed on one side of the mounting plate 13, the arc-shaped guide rod 37 is fixedly installed between one ends of the two fixed plates 38, the moving block 36 is slidably sleeved on the arc-shaped guide rod 37, the nozzle 35 is installed on one side of the moving block 36, the moving rod 41 is located on the side of the moving block 36 away from the nozzle 35, and the moving rod 41 is slidably set between the two fixed plates 38, a strip groove 42 is opened at one end of the moving rod 41, and an insertion rod 43 is inserted into the inside of the strip groove 42, and one end of the insertion rod 43 is fixed on the moving block 36, one end of the hinged rod 44 is hinged to the top end of the moving rod 41, and the other end of the hinged rod 44 is hinged to the surface edge of the turntable 45.

[0042] like Figure 1-Figure 12 As shown, two vertical rods 39 are provided on one side of the arc-shaped guide rod 37, and both ends of each vertical rod 39 are fixedly connected to two fixing plates 38 respectively. A sliding sleeve 40 is slidably provided on each vertical rod 39, and each sliding sleeve 40 is fixedly installed on one side of the moving rod 41; When the turntable 45 rotates, the movable rod 41 is driven to move up and down along the length direction of the vertical rod 39 under the action of the hinged rod 44. When the movable rod 41 moves, it drives the insertion rod 43 to move through the strip groove 42.

[0043] like Figure 1-Figure 12As shown, the conveying assembly includes a hot air blower 32, an output pipe 33 and two hoses 34. A top plate 31 is fixed to the top of the mounting plate 13. The hot air blower 32 is fixedly mounted on the top of the top plate 31. The output end of the hot air blower 32 is fixedly connected to one end of the output pipe 33. The other end of the output pipe 33 is connected to one end of the two hoses 34 through a three-way valve. The other ends of the two hoses 34 are respectively connected to the input ends of the two nozzles 35. During the coating process, the hot air blower 32 can be controlled to work. The hot air blower 32 can deliver hot air to the nozzle 35 through the output pipe 33 and the two hoses 34.

[0044] like Figure 1-Figure 12 As shown, the first transmission assembly includes a first driving sprocket 28, a first driven sprocket 29, a first chain 30, a worm wheel 26, a worm 27 and a polished rod 53, the polished rod 53 is rotatably arranged on one side of one of the mounting seats 12, the worm wheel 26 is fixedly mounted on one end of one of the motors 15, and the worm wheel 26 is located below the polished rod 53, the worm 27 is fixedly mounted on the surface of the polished rod 53, the worm 27 and the worm wheel 26 are meshed with each other, the first driving sprocket 28 is fixedly mounted on one side of one of the driving wheels 19, the first driven sprocket 29 is fixedly mounted on one end of the polished rod 53 away from the worm 27, and the first chain 30 is sleeved on the first driving sprocket 28 and the first driven sprocket 29; When the driving wheel 19 rotates, the driving wheel 19 drives the first active sprocket 28 to rotate, and under the action of the first chain 30, it can drive the first driven sprocket 29 to rotate, so that the light rod 53 can be rotated, and the light rod 53 can drive the worm 27 to rotate. Since the worm 27 and the worm wheel 26 are meshed with each other, when the worm 27 rotates, it can drive the worm wheel 26 to rotate, so that the driving roller 25 can be rotated. That is, in the process of the arc ring 21 driving the unwinding roller 22 to rotate to wind the annular casting, the driving roller 25 can drive the casting to rotate synchronously to achieve winding of different positions of the casting.

[0045] like Figure 1-Figure 12 As shown, each abutting assembly includes a abutting roller 49, a rotating frame 54, a vertical plate 52, two cross bars 50 and two springs 51. The vertical plate 52 is fixedly mounted on the top of the mounting seat 12. The two cross bars 50 are slidably mounted on the vertical plate 52. The rotating frame 54 is fixedly mounted on one end of the two cross bars 50. The abutting roller 49 is rotatably mounted in the rotating frame 54. The surface of the abutting roller 49 abuts against the surface of the casting. Each spring 51 is sleeved on the surface of a cross bar 50. The two ends of each spring 51 are respectively connected to the rotating frame 54 and the vertical plate 52. In the initial state, the spring 51 is in a compressed but not completely compressed state. The compressed spring 51 can always drive the pressing roller 49 to move toward the side close to the casting, thereby pressing the casting and ensuring that the casting can be stably placed between the two driving rollers 25. At the same time, the pressing roller 49 is rotatably arranged in the rotating frame 54, which can effectively reduce the friction between the casting and the pressing roller 49, thereby protecting the casting. By setting up two driving rollers 25, annular castings of different diameters can be placed, and by means of the retractable pressing roller 49, castings of different thicknesses can be positioned, thereby enabling coating processing of annular castings of different sizes, with a wide range of applications and high practicality.

[0046] like Figure 1-Figure 12 As shown, an annular groove 23 is provided on the surface of the mounting plate 13, and an annular plate 24 is rotatably provided inside the annular groove 23. One end of the annular plate 24 is fixedly connected to the unwinding roller 22. By setting a sliding connection between the annular groove 23 and the annular plate 24, the unwinding roller 22 can be guided during rotation.

[0047] The specific working process of the present invention is as follows: First, the casting to be coated is placed between the two driving rollers 25, and the casting is positioned by four abutting rollers 49. Then, one end of the protective film on the unwinding roller 22 is adhered to one side of the casting. The motor 15 is controlled to work. The motor 15 can drive the pulley 16 connected to its output end to rotate. Under the action of the belt 17, multiple pulleys 16 can realize synchronous rotation. When the pulley 16 rotates, it can drive the driving wheel 19 to rotate. Since the driving wheel 19 and the arc ring 21 are in contact with each other, when the driving wheel 19 rotates, it can drive the arc ring 21 to rotate, so that the unwinding roller 22 on the arc ring 21 can realize rotation, so that the protective film on the unwinding roller 22 can be wound on the casting, so as to realize the winding coating of the annular casting; At the same time, when the driving wheel 19 rotates, the driving wheel 19 drives the first active sprocket 28 to rotate, and under the action of the first chain 30, the first driven sprocket 29 can be driven to rotate, so that the light rod 53 can be rotated, and the light rod 53 can drive the worm 27 to rotate. Since the worm 27 and the worm wheel 26 are meshed with each other, when the worm 27 rotates, the worm wheel 26 can be driven to rotate, so that the driving roller 25 can be rotated, that is, in the process of the arc ring 21 driving the unwinding roller 22 to rotate to wind the annular casting, the driving roller 25 can drive the casting to rotate synchronously, so as to realize the winding of different positions of the casting; During the coating process, the hot air blower 32 can be controlled to work. The hot air blower 32 can deliver hot air to the nozzle 35 through the output pipe 33 and the two hoses 34. The hot air can be blown out through the nozzle 35 to achieve heating of the protective film. That is, during the coating process, the position where the coating has just been completed can be heated, so that the protective film can fit tightly to the surface of the casting, thereby improving the protection effect on the casting, reducing damage to the casting during transportation, and improving the corrosion resistance, rust resistance and anti-oxidation effect of the casting.

[0048] During this process, when the pulley 16 rotates, the pulley 16 can drive the second active sprocket 46 to rotate synchronously. Under the action of the second chain 48, the second active sprocket 46 can drive the second driven sprocket 47 to rotate when it rotates, so that the turntable 45 can be rotated. When the turntable 45 rotates, under the action of the hinged rod 44, the moving rod 41 will be driven to move up and down along the length direction of the vertical rod 39. When the moving rod 41 moves, it drives the insertion rod 43 to move through the strip groove 42. When the insertion rod 43 moves, it can drive the moving block 36 to move along the arc guide rod 37, so that the nozzle 35 can be swung, and the nozzle 35 can blow and heat multiple surfaces of the casting to ensure that each surface of the casting can be tightly attached to the protective film.

[0049] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
