[0023] The following further describes in detail the embodiments of the present utility model in conjunction with the accompanying drawings and embodiments

[0024] As shown in the attached Figure 1 to the attached Figure 6 as shown

[0025] Embodiment 1: The present utility model provides an automatic tire tread feeding device for a tire building machine, including a working platform 1, an inverting mechanism 2 and a conveyor and feeding rack 3. The conveyor and feeding rack 3 is fixedly installed on the top of the working platform 1. The inverting mechanism 2 includes a fixed seat 201, an electric push rod 202, a driving block 203, a positioning rod 204 and an inverting frame 205. The fixed seat 201 is fixedly installed on the top of the working platform 1, and the electric push rod 202 is fixedly installed inside the fixed seat 201. The driving block 203 is inserted into the fixed seat 201, and the positioning rod 204 is inserted into the fixed seat 201. One end of the push rod of the electric push rod 202 is rotatably connected to the side of the positioning rod 204. The inverting frame 205 is rotatably connected to the inside of the fixed seat 201, and the manipulator places the tire tread material inside the shutter car on the inverting frame 205

[0026] In the embodiments of the present disclosure, a reversing gear 2053 is provided at one end of the rotating shaft of the reversing frame 205, and a driving rack 2031 is provided at the top of the driving block 203. When the horizontal carrier plate 2051 is in the horizontal state, the teeth of the reversing gear 2053 and the driving rack 2031 are disengaged. The reversing gear 2053 is arranged on the moving path of the driving rack 2031. During use, the robotic arm can identify and carry the tire fabric stored inside the shutter vehicle, and place the tire fabric on the horizontal carrier plate 2051 in the horizontal state. Through the reversing mechanism 2, the tire fabric can be reversed and dropped onto the top of the conveying and feeding rack 3 for continuous conveying and feeding the tire forming machine. When the horizontal carrier plate 2051 is in the horizontal state, at this time, the electric push rod 202 is in the extended state. Controlling the electric push rod 202 to contract can realize the reversing action of the reversing frame 205. When the electric push rod 202 contracts, it can drive the driving block 203 to move through the positioning rod 204. During the movement of the driving block 203, the driving rack 2031 will engage with the teeth of the reversing gear 2053, thereby driving the reversing frame 205 to rotate to realize the reversing action. After the tire fabric is reversed and dropped onto the top of the conveying and feeding rack 3, then by making the electric push rod 202 extend, the reversing mechanism 2 can be driven to reset (restore the horizontal state of the horizontal carrier plate 2051), which is convenient and flexible to use.

[0027] In the embodiments of the present disclosure, the frame body of the reversing frame 205 is in an "L" shape, and a horizontal carrier plate 2051 and a vertical baffle 2052 are provided outside the reversing frame 205. The included angle between the horizontal carrier plate 2051 and the vertical baffle 2052 is ninety degrees. A reset support plate 101 is provided on the side of the working platform 1, and when the horizontal carrier plate 2051 is in the horizontal state, it will be supported by the reset support plate 101. During use, during the reversing process of the reversing frame 205, when the rotation angle of the reversing frame 205 is less than ninety degrees, the vertical baffle 2052 can provide a blocking and supporting effect on the tire fabric, thereby avoiding the phenomenon that the tire fabric slips prematurely and cannot be reversed. When the rotation angle of the reversing frame 205 is greater than ninety degrees, at this time, the tire fabric can automatically reverse and fall onto the top of the conveying and feeding rack 3 under the action of gravity, and the use is stable.

[0028] In the embodiments of the present disclosure, the outer surface of the rod body of the positioning rod 204 is provided with threads, and the positioning rod 204 is screwed into the inside of the driving block 203 through the threads on the rod body. During use, the maximum rotation angle of the flipping frame 205 can be adjusted by the positioning rod 204. When the positioning rod 204 is rotated, the positioning rod 204 can drive the driving block 203 to move and change its position through the threads on the rod body. Since the teeth of the driving rack 2031 and the flipping gear 2053 do not mesh when the horizontal carrier plate 2051 is in a horizontal state, the flipping frame 205 will not change its angle during adjustment. Moreover, since the maximum telescopic trajectory and distance of the electric push rod 202 are fixed, the change in the position of the driving block 203 changes the maximum rotation angle of the flipping gear 2053 that the driving rack 2031 can drive when the driving block 203 moves, that is, the rotation angle of the flipping frame 205. The adjustment is convenient and can meet the requirements of different tire fabric feeding uses, with extremely strong adaptability.

[0029] In the embodiments of the present disclosure, the cross-sectional shape of the block body of the driving block 203 is "T" shaped, and an orbital groove 2011 is provided inside the fixed seat 201. The driving block 203 is inserted into the inside of the orbital groove 2011. The orbital groove 2011 can limit the movement trajectory of the driving block 203 during movement and adjustment, thereby avoiding the phenomenon of the driving block 203 skewing or twisting during use, which may cause the device to jam and fail, and ensuring stable use.

[0030] The specific usage and function of this embodiment:

[0031] In the present utility model, according to the actual feeding requirement, the maximum flipping angle of the flipping frame 205 is adjusted. The positioning rod 204 can be used to control the maximum rotation angle of the flipping frame 205. When the positioning rod 204 is rotated, the positioning rod 204 can drive the driving block 203 to move and change its position through the rod thread. Since the driving rack 2031 and the teeth of the flipping gear 2053 do not mesh when the horizontal carrier plate 2051 is in a horizontal state, the flipping frame 205 will not change its angle during the adjustment. Moreover, since the maximum telescopic trajectory and distance of the electric push rod 202 are fixed, the change in the position of the driving block 203 changes the maximum rotation angle of the flipping gear 2053 that the driving rack 2031 can drive when the driving block 203 moves, that is, the rotation angle of the flipping frame 205. The adjustment is convenient and can meet the requirements of different tire fabric feeding. The robotic arm can identify and carry the tire fabric stored inside the shutter truck and place the tire fabric on the horizontal carrier plate 2051 in a horizontal state. Through the flipping mechanism 2, the tire fabric can be flipped and dropped onto the top of the conveying and feeding rack 3 for continuous conveying and feeding the tire forming machine. When the horizontal carrier plate 2051 is in a horizontal state, the electric push rod 202 is in an extended state at this time. Controlling the contraction of the electric push rod 202 can achieve the flipping action of the flipping frame 205. When the electric push rod 202 contracts, it can drive the driving block 203 to move through the positioning rod 204. During the movement of the driving block 203, the driving rack 2031 will mesh with the teeth of the flipping gear 2053, thereby driving the flipping frame 205 to rotate and achieve the flipping action. After the tire fabric is flipped and dropped onto the top of the conveying and feeding rack 3, then by making the electric push rod 202 extend, it can drive the flipping mechanism 2 to reset (restore the horizontal state of the horizontal carrier plate 2051). During the flipping process of the flipping frame 205, when the rotation angle of the flipping frame 205 is less than 90 degrees, the vertical baffle 2052 can provide a blocking and supporting effect on the tire fabric, thereby preventing the tire fabric from slipping prematurely and causing the phenomenon of inability to flip. When the rotation angle of the flipping frame 205 is greater than 90 degrees, at this time, the tire fabric can automatically flip and fall onto the top of the conveying and feeding rack 3 under the action of gravity.
