[0001] The invention relates to the technical field of rubber tire punching, in particular to a rubber tire punching device which is convenient for loading and unloading. Background Art

[0002] Rubber tires are ground-contacting and rolling annular elastic rubber products installed on various vehicles or machinery. They are usually installed on metal rims, can support the vehicle body, buffer external impacts, achieve contact with the road surface and ensure the driving performance of the vehicle. In order to improve the grip and driving safety on slippery roads, rubber tires are usually punched to help the tires better drain water from the road surface and reduce hydroplaning. However, due to the existing rubber tire punching device, the needle will generate a lot of friction heat when punching the rubber tire. The high temperature may cause the rubber material to partially melt or soften, causing the rubber material at the edge of the hole to stick together, forming an irregular hole shape, which reduces the tire punching quality and efficiency.

[0033] like Figure 1 , Figure 5 and Figure 6 As shown, the punching mechanism 4 includes a trigger block 40, a hollow column 41, a first spring 42, a threaded column 43, a screw rod 44, a movable connecting frame 45, a needle plate 46 and a guide connecting bracket 47. The trigger block 40 is connected to the lower side of the first rotating column 33, and the hollow column 41 is slidably connected to the upper rear part of the mounting frame 1. The trigger block 40 and the hollow column 41 are extruded and matched. The first spring 42 is connected between the upper and lower parts of the hollow column 41 and the mounting frame 1.

The inner side of the upper part of the mounting frame 1 is connected to the guide connecting bracket 47, and the needle plate 46 is slidably connected to the guide connecting bracket 47.

[0034] When using the present invention, firstly, the mounting frame 1 is placed in the punching area of ​​the rubber tire 0, and then the rubber tire 0 is placed on the left side of the conveyor 2, and the conveyor 2 is started to convey the rubber tire 0 to the right. When the rubber tire 0 moves to the closing plate 31, the cylinder 30 is started to push the closing plate 31 to move upward until the upper side of the rubber tire 0 contacts the rotating disk 39, and the rubber tire 0 is clamped and closed by the cooperation of the rotating disk 39 and the closing plate 31, and then the air pump 38 is started to fill the tire 0 with gas through the fixed pipe 37 and the rotating disk 39, and then the motor 32 is started to drive the first rotating column 33 to rotate, and the second rotating column 34 is rotated through the belt 35, so that the missing gear 36 is meshed with the connecting gear 310, and the rotating disk 39 is driven to rotate intermittently, so that the rubber tire 0 is intermittently rotated to adjust the punching position, and when the internal pressure of the tire 0 is too large, the safety valve is opened to reduce the internal pressure of the tire 0. When the first rotating column 33 rotates, the trigger block 40 is driven to rotate. When the trigger block 40 contacts the hollow column 41 and squeezes the hollow column 41 to move backward, the first spring 42 is squeezed and contracted, and the threaded column 43 and the screw rod 44 are triggered to rotate, so that the movable connecting frame 45 moves forward, and the needle plate 46 moves forward to punch the rubber tire 0. When the trigger block 40 is separated from the hollow column 41, the first spring 42 rebounds, so that the hollow column 41 is reset, and the threaded column 43 and the screw rod 44 are triggered to rotate and reset, so that the movable connecting frame 45 and the needle plate 46 move backward and reset to be separated from the rubber tire 0. Subsequently, the rubber tire 0 rotates to adjust the punching position. After the needle plate 46 is separated from the rubber tire 0, the internal gas of the tire 0 is discharged from the punching part to cool the punching area, thereby effectively avoiding the irregular hole shape caused by high-temperature melting or softening of the punching part of the tire 0, thereby improving the punching quality and efficiency.

[0035] like Figure 1 and Figure 7 As shown, a prompt mechanism 5 is also included, which includes a fixed frame 50, a guide knocking column 51, a second spring 52 and a prompt bell 53.

The second spring 52 is connected between the guide knocking column 51 and the fixed frame 50. The prompt bell 53 is connected to the upper part of the mounting frame 1, and the prompt bell 53 is located in front of the fixed tube 37.

[0036] By using the prompt mechanism 5 of the device, the number of revolutions of the rubber tire 0 can be prompted. When the connecting gear 310 rotates, the fixing frame 50 is driven to move. When the fixing frame 50 moves to the prompt bell 53, the guide knocking column 51 knocks the prompt bell 53 under the action of the second spring 52, causing the prompt bell 53 to ring, thereby prompting the number of revolutions of the rubber tire 0, so as to know the progress of the punching of the rubber tire 0.

[0037] like Figure 1 and Figure 8 As shown, a heat dissipation mechanism 6 is also included, which includes a connecting support frame 60, a fixed connecting frame 61 and a fan 62. The connecting support frame 60 is connected to the lower side of the guide connecting bracket 47, the connecting support frame 60 is connected to the fixed connecting frame 61, and the fixed connecting frame 61 is provided with a fan 62.

[0038] The heat dissipation mechanism 6 of the device can accelerate the heat dissipation of the needle plate 46. When the needle plate 46 is reset, the fan 62 is started to blow air upward, thereby accelerating the heat dissipation of the needle plate 46 and avoiding affecting the quality of tire 0 punching.

[0039] like Figure 1 and Fig. 9 As shown, a protective mechanism 7 is also included, and the protective mechanism 7 includes a fixed connection support frame 70 and a protective frame 71. The left and right sides of the mounting frame 1 are connected to the fixed connection support frames 70, and the front and rear protective frames 71 are connected between the fixed connection support frames 70. The protective frames 71 are rotatably provided with multiple rollers to facilitate the transportation of the tire 0.

[0040] By using the protection mechanism 7 of the device, the tire 0 can be protected. When the conveyor 2 conveys the tire 0, the protection frame 71 limits the position of the tire 0 to prevent the tire 0 from falling.

[0041] like Figure 1 and Fig. 9 As shown, a centering mechanism 8 is also included, and the centering mechanism 8 includes a connecting and fixing column 80 and a centering plate 81. The connecting and fixing columns 80 are connected to the side of the left part of the protective frame 71 that are close to each other, and the centering plates 81 are connected to the side of the connecting and fixing columns 80 that are close to each other. The centering plates 81 are all folded to facilitate guiding the tire 0 to be centered.

[0042] By using the centering mechanism 8 of the device, the tire 0 can be centered and limited. When the tire 0 moves, the tire 0 passes between the centering plates 81, thereby playing the role of centering and limiting the tire 0 and preventing the moving direction of the tire 0 from deviating.
