[0034] like Figure 1 , Figure 5 and Figure 6 As shown, the measuring mechanism 4 includes a fixed connecting frame 40, a guide frame 41, a spring 42, a movable connecting plate 43, a displacement sensor 44 and a controller 45. The fixed connecting frame 40 is connected to the left side of the connecting fixed frame 311, and the guide frame 41 is slidably connected to the rear of the fixed connecting frame 40. The rear of the guide frame 41 is a hollow structure for guiding waste materials. A spring 42 is connected between the guide frame 41 and the fixed connecting frame 40. The left side of the fixed connecting frame 40 is detachably connected to the movable connecting plate 43 by bolts. The rear side of the movable connecting plate 43 is connected to the displacement sensor 44. The displacement sensor 44 is located in front of the guide frame 41.

The controller 45 is electrically connected to the displacement sensor 44, and the trackless cylinder 31 is electrically connected to the controller 45.

[0035] When using the present invention, firstly, the base frame 1 is placed in the rubber tire production pattern engraving area, and then the rubber tire to be engraved is horizontally placed on the base frame 1, and then the connecting plate frame 33 is rotated to make the connecting column 35 vertically downward, and then the connecting cylinder 30 on the fixed bracket 2 is started to make the trackless cylinder 31 move downward, so that the air bag 38 moves downward and is located at the inner ring of the rubber tire, and then the air pump 36 is started to inflate the air bag 38 through the connecting pipe 37 to make it expand and fix the rubber tire from the inner ring. After fixing, the connecting cylinder 30 is started to reset the trackless cylinder 31, and then the connecting plate frame 33 is rotated to restore the connecting column 35 to a horizontal state, so that the rubber tire is rotated to a vertical state, thereby automatically clamping and loading the rubber tire, saving manpower and improving the rubber tire. The rubber tire production efficiency is improved. Then, according to the rubber tire pattern engraving requirements, the position of the connecting bracket 39 is slidably adjusted. After the adjustment, the trackless cylinder 31 is started to drive the moving frame 32 to move, so that the outer ring of the rubber tire contacts the cutter 312. At the same time, the second motor 310 is started to drive the connecting fixed frame 311 to rotate, so that the cutter 312 rotates to engrave the pattern on the outer ring of the rubber tire. By starting the first motor 34, the connecting column 35 is driven to rotate, so that the rubber tire rotates, and the rubber tire engraving position can be adjusted. The waste generated by the engraving is guided out through the guide sheet on the cutter 312 to separate it from the rubber tire, thereby playing a role in guiding the waste generated by the engraving when the rubber tire is engraved, saving manpower, and improving the rubber tire engraving efficiency. The waste generated by carving is guided out through the guide sheet on the cutter 312 and passed through the guide frame 41 to avoid the waste rebound. When the cutter 312 carves the rubber tire, the position of the movable connecting plate 43 on the fixed connecting frame 40 is adjusted according to the depth requirement of the pattern carving, and then the distance between the displacement sensor 44 and the guide frame 41 is adjusted. When the cutter 312 carves the rubber tire, the guide frame 41 contacts the carved pattern on the tire and is squeezed to move forward, and the spring 42 is squeezed and contracted. At this time, the displacement sensor 44 monitors the distance between the guide frame 41. When the displacement sensor 44 detects that the distance between the guide frame 41 changes, it indicates that there is a deviation in the pattern carving depth. The controller 45 controls the trackless cylinder 31 to be closed, so that the rubber tire stops moving, thereby automatically detecting the pattern depth, saving manpower, and improving the efficiency and quality of rubber tire carving.

[0036] like Figure 1 and Figure 7 As shown, it also includes a rotating mechanism 5, which includes a connected fixed support frame 50 and a third motor 51.

[0037] By using the rotating mechanism 5 of the present device, the rotation of the connecting plate frame 33 can be automatically controlled. By starting the third motor 51 connected to the fixed support frame 50, the connecting plate frame 33 is driven to rotate, thereby automatically controlling the rotation of the connecting plate frame 33, saving manpower and improving operational convenience.

[0038] like Figure 1 and Figure 7 As shown, it also includes an adjusting mechanism 6, which includes a fourth motor 60 and a screw 61. The fourth motor 60 is connected to the front side of the right part of the base frame 1, the controller 45 is electrically connected to the fourth motor 60, and the screw 61 is connected to the output shaft of the fourth motor 60.

[0039] By using the adjustment mechanism 6 of the device, the position of the connecting bracket 39 can be automatically adjusted. By starting the fourth motor 60, the screw rod 61 is driven to rotate, so that the connecting bracket 39 moves, thereby automatically adjusting the position of the connecting bracket 39, saving manpower, and improving the convenience of operation. When the displacement sensor 44 detects a change in the distance between the guide frame 41, the controller 45 controls the fourth motor 60 to start and adjusts the engraving depth of the cutter 312 on the rubber tire.

[0040] like Figure 1 and Figure 8 As shown, it also includes a collecting mechanism 7, which includes a fixed support plate 70 and a collecting box 71. The fixed support plate 70 is connected to the upper middle side of the base frame 1, and the collecting box 71 is connected to the upper side of the fixed support plate 70. The collecting box 71 is located below the cutter 312 to facilitate receiving waste.

[0041] The collecting mechanism 7 of the device can be used to collect engraving waste. The engraving waste passes through the guide frame 41 and falls into the collecting box 71, thereby collecting the engraving waste and facilitating cleaning.

[0042] like Figure 1 and Figure 8 As shown, a conveying mechanism 8 is also included, and the conveying mechanism 8 includes a connecting support frame 80 and a conveyor belt 81. The connecting support frame 80 is connected to the right side of the base frame 1, and the conveyor belt 81 is provided on the connecting support frame 80.

[0043] The conveying mechanism 8 of the device can be used to convey tires. When loading the tires, the tires can be placed on the conveyor belt 81, and then the conveyor belt 81 can be started to transport the tires to the chassis 1. The tires are then removed and placed on the chassis 1. After the tires are engraved, the tires are placed on the conveyor belt 81 and transported to the next processing area, thereby playing a role in conveying the tires and improving the tire production efficiency.
