[0026] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0027] like Figure 1 As shown, this utility model provides a tire spraying machine suitable for simultaneously spraying the inner and outer surfaces of a tire. The tire workpiece 500 is sequentially arranged with a front conveying station 100, a centering station 200, a spraying station 300, and a rear conveying station 400. The tire workpiece 500 is sent from the front conveying station 100 to the centering station 200 for centering, and then sent to the spraying station 300 for spraying. After the spraying is completed, it is sent out from the rear conveying station 400.

[0028] like Figure 1 As shown, a forward-curving roller conveyor 1 and a modular belt 2 are provided on the front conveyor station 100, with the forward-curving roller conveyor 1 positioned before the modular belt 2. Several forward-curving conveyor rollers 11 are provided on the forward-curving roller conveyor 1, and several forward-curving stop rollers 12 are provided on both sides of the forward-curving conveyor rollers 11. Figure 2As shown, on the frame 21 of module belt 2, conveyor shafts 22 are respectively arranged at the front and rear ends along the conveying direction of the tire workpiece 500. The conveyor shafts 22 are perpendicular to the conveying direction of the tire workpiece 500. One end of the conveyor shaft 22 is the drive shaft and is connected to the drive mechanism, while the other end of the conveyor shaft 22 is the driven shaft. Several conveyor wheels are arranged axially on the conveyor shafts 22, and several protrusions 221 are arranged on the outer circumferential surface of the conveyor wheels. The protrusions 221 protrude radially on the outer wall surface of the conveyor wheels. Several conveyor strips 23 and several idler rollers 24 are arranged on the frame 21 between the two conveyor shafts 22. The conveyor strips 23 are parallel to the conveying direction of the tire workpiece 500 and perpendicular to the conveyor shafts 22, while the idler rollers 24 are parallel to the conveyor shafts 22 and perpendicular to the conveying direction of the tire workpiece 500. The conveyor strips 23 are wear-resistant strips. Side baffle assemblies 25 are respectively provided on the two outer sides of the frame 21, parallel to the conveying direction of the tire workpiece 500. These assemblies are used to ensure that the tire workpiece 500 is conveyed forward along the conveying track during pre-positioning, preventing it from deviating from its designated path. Each side baffle assembly 25 includes a gate 251 that can move closer to or further away from the conveying track. Several vertical side baffle rollers 2512 are provided on the gate plate 2511 of the gate 251. The gate 251 is connected to a push rod 253 via a rotating shaft 252. The push rod 253 is connected to a push arm 254, which is connected to the drive rod of a push cylinder 255. The push cylinder 255, through the drive rod, sequentially drives the push arm 254, the push rod 253, and the rotating shaft 252, causing the gate 251 to rotate and move closer to or further away from the conveying track.

[0029] like Figure 1 As shown, the rear conveyor station 400 is equipped with a curved roller conveyor 5 and a straight roller conveyor 6, with the curved roller conveyor 5 positioned before the straight roller conveyor 6. The curved roller conveyor 5 has several curved conveyor rollers 51, and several curved guide rollers 52 are positioned on both sides of each curved conveyor roller 51. The straight roller conveyor 6 has several straight conveyor rollers 61, and several straight guide rollers 62 are positioned on both sides of each straight conveyor roller 61. Sections of both the curved roller conveyor 5 and the straight roller conveyor 6 are equipped with heat dissipation devices 7 to cool the coating on the coated tire workpiece 500.

[0030] like Figure 1 As shown, a centering device 3 is installed on the centering station 200. (As indicated...) Figure 3 As shown, the centering device 3 has a liftable lifting seat 32 mounted on its support 31. The lifting seat 32 is slidably mounted on the lifting rail of the support 31 via a slider. The lifting seat 32 is connected to a lifting cylinder 33, which drives the lifting seat 32 to move up and down along the lifting rail. A centering component 34 is mounted on the lifting seat 32. Figure 4As shown, the centering assembly 34 includes a centering plate 341 and several support claws 342. The centering plate 341 is fixedly connected to the lifting base 32. The support claws 342 are arranged in a circumference and can slide radially on the centering plate 341. Several radial slide rails are provided on the centering plate 341 corresponding to the support claws 342. Each support claw 342 is slidably mounted on its corresponding radial slide rail via a slider and can move along its corresponding radial slide rail to open or close. Each support claw 342 is hinged to a hinge seat 344 via a connecting rod 343. The hinge seat 344 is sleeved on a spindle 345 and can move up and down along the spindle 345. The spindle 345 is vertically inserted into the center of the centering plate 341. One of the support claws 342 is equipped with a push-pull assembly 346, which is connected to the drive rod of a push-pull cylinder 347. The cylinder body of the push-pull cylinder 347 is connected to the lifting seat 32. When the push-pull cylinder 347 drives one support claw 342 to open or close via the push-pull assembly 346, the support claw 342 drives the hinge seat 344 to rise and fall along the spindle 345 via the corresponding connecting rod 343. The hinge seat 344 drives the corresponding support claw 342 to open or close synchronously via other connecting rods 343, thereby achieving the centering of the tire workpiece 500. Before being sent to the spraying station 300, the tire workpiece 500 is centered by the centering device 3 to ensure the centering of the tire workpiece 500 when it is sent into the spraying station 300, improve the uniformity of the spraying, and improve the quality of the tire.

[0031] like Figure 1 As shown, a spraying device 4 is installed on the spraying station 300. (As indicated...) Figures 5 to 7As shown, the spraying cabinet 41 of the spraying device 4 is equipped with a rotating seat 42, which is connected to and driven by a rotating mechanism 43. The spraying cabinet 41 is equipped with a first spraying mechanism 44, a second spraying mechanism 45, and a third spraying mechanism 46. The first spraying mechanism 44 is used to spray the outer surface of the tire workpiece 500, the second spraying mechanism 45 is used to spray the inner surface of the tire workpiece 500, and the third spraying mechanism 46 is used to spray the bottom and side surfaces of the tire workpiece 500. The first spraying mechanism 44 and the second spraying mechanism 45 are mounted on a lifting frame 471 of the lifting mechanism 47. The lifting frame 471 is connected to a second lifting cylinder 472, which can drive the first spraying mechanism 44 and the second spraying mechanism 45 to lift and lower, spraying various axial parts of the inner and outer surfaces of the tire workpiece 500. The third spraying mechanism 46 is mounted on the cabinet plate of the spraying cabinet 41, at a position corresponding to the bottom and side surfaces of the tire workpiece 500. The first spraying mechanism 44, the second spraying mechanism 45, and the third spraying mechanism 46 are each equipped with a spray gun (first spray gun 441, second spray gun 451, and third spray gun 461). The spray guns (first spray gun 441 and second spray gun 451) of the first spraying mechanism 44 and the second spraying mechanism 45 are connected to the translation components (first translation component 443 and second translation component 453) through connecting rods (first connecting rod 442 and second connecting rod 452). The translation components are slidably mounted on the lifting frame 471 of the lifting mechanism 47. The translation components (first translation component 443 and second translation component 453) are connected to translation cylinders (first translation cylinder 444 and second translation cylinder 454). The translation cylinders can drive the translation components to move horizontally on the lifting frame 471, thereby moving the spray guns (first spray gun 441 and second spray gun 451) to adjust the spraying position to adapt to different specifications of tire workpieces 500. The third spray gun 461 of the third spraying mechanism 46 is connected to the drive rod of the third translation cylinder 462. The cylinder body of the third translation cylinder 462 is mounted on the cabinet plate of the spraying cabinet 41. The third translation cylinder 462 drives the third spray gun 461 to move and adjust the spraying position through the drive rod to adapt to different specifications of tire workpieces 500. The workpiece feeding side and the workpiece delivery side of the spraying cabinet 41 are respectively provided with liftable side doors 48. The side doors 48 are connected to the lifting cylinder 49, which can drive the side doors 48 to rise and fall. During spraying, the side doors 48a on the workpiece feeding side and 48b on the workpiece delivery side are both closed. When the tire workpiece 500 is to be fed into the spraying cabinet 41, the side door 48a on the workpiece feeding side is opened. When the tire workpiece 500 is to be delivered out of the spraying cabinet 41, the side door 48b on the workpiece delivery side is opened. The spraying device 4 can simultaneously spray the outer surface, inner surface, and bottom side of the tire workpiece 500 through three sets of spraying mechanisms, which improves spraying efficiency and ensures the uniformity of spraying on all sides of the tire, thereby improving the quality of the tire.Of course, for tire workpiece 500 where not all surfaces need to be painted, the painting mechanism corresponding to the surface to be painted can be activated only to paint the surface to be painted.

[0032] like Figure 1 As shown, the spraying device 4 has a bracket mechanism 8 on both the inlet and outlet sides. The bracket mechanism 8a on the inlet side is located below the centering component 34 of the centering device 3, and the bracket mechanism 8b on the outlet side is located before the rear curved roller conveyor 5 of the rear conveying station 400. Figure 8 As shown, the pallet mechanism 8 has a conveyor belt assembly 82 and a conveying device 83 on its pallet 81. The conveyor belt assembly 82 is located on the receiving side or the discharge side of the conveying device 83, and can deliver the tire workpiece 500 to or from the conveying device 83. The conveying device 83 is located near the spraying device 4 and can move into or out of the spraying cabinet 41 of the spraying device 4. Figure 9 As shown, the conveying device 83 is movably mounted on the conveying track 84 via a slider. The conveying device 83 is connected to the conveying cylinder 85, which can drive the conveying device 83 to move along the conveying track 84 into or out of the spray booth 41. When the tire workpiece 500 is to be sent into the spray booth 41, the conveying device 83 of the incoming side bracket mechanism 8a lifts the tire workpiece 500 from the conveyor belt assembly 82 and enters the spray booth 41, places the tire workpiece 500 on the spraying position of the rotating seat 42, and then withdraws. After the tire workpiece 500 is sprayed, the conveying device 83 of the outgoing side bracket mechanism 8b enters the spray booth 41, lifts the tire workpiece 500 from the rotating seat 42, withdraws it together, and then places it on the conveyor belt assembly 82. Figure 9 As shown, the conveying device 83 includes a base frame 831 slidably mounted on a conveying track 84 and a liftable top frame 832. The opposite sides of the top frame 832 are connected to the base frame 831 via two intersecting swing plates 833. One end of each swing plate 833 is connected to the top frame 832, and the other end is connected to the base frame 831. A swing rod 834 passes through the intersection of the two swing plates 833, allowing each pair of swing plates 833 to swing around the swing rod 834 to raise or lower. A connecting plate 835 connects the corresponding swing plates 833 on the same side of the base frame 831. The connecting plate 835 is connected to the drive rod of a lifting cylinder 836. The cylinder body of the lifting cylinder 836 is connected to the base frame 831. The lifting cylinder 836, through the connecting plate 835, can drive the swing plates 833 to swing, raising or lowering the top frame 832. A lifting plate 837 is fixed to the top surface of the top frame 832, increasing the lifting area and making the conveying more stable and reliable.
