[0040] refer to Figure 1-3, an embodiment of the present application discloses a tire transition layer cutting mechanism, the cutting mechanism comprising:

[0041] Two groups of cutting components 10, each group of cutting components 10 includes a cutter, a cutting swing arm 12, a cutter bracket 13, a cylinder 15, and a cylinder mounting frame 14.

[0043] The width adjustment component 20 includes a width adjustment motor 21, a width adjustment screw member 22, and a width measurement sensor 23. The width adjustment screw member 22 passes through the cutting component 10, and the width adjustment motor 21 is connected to the width adjustment screw member 22. The width measurement sensor is used to measure the cutting width and position. The width adjustment screw member 22 includes a width adjustment screw 221, a first fixing member 222 and a second fixing member 223 arranged at both ends of the second mounting plate 42, and a synchronous belt 224.

[0044] refer to Figure 2The first fixing member 222 and the second fixing member 223 are respectively provided with pin holes, and the width adjustment screw 221 passes through the pin holes on the first fixing member 222, the second fixing member 223 and the second part of the cutter bracket 13. The synchronous belt 224 is transmission-connected to one end of the width adjustment screw 221, and is drivingly connected to the width adjustment motor 21. The width adjustment motor 21 is a servo motor, which drives the synchronous belt 224 and the width adjustment screw 221 to rotate forward and reverse, thereby driving the cutting assembly 10 to reciprocate on the guide slider 412 to adjust the cutting width. The width adjustment screw 221 is a ball screw, which can reduce the error caused by the screw clearance and has higher accuracy. One or two width measuring sensors 23 can be set, and a laser reflection sensor is used to measure the cutting width and feedback data.

[0045] The deflection correction assembly 30 includes a deflection correction screw component 31 and a deflection correction motor 32. The deflection correction screw component 31 is arranged on one side of the cutting assembly 10 and connected to the deflection correction motor 32. The deflection correction screw component 31 includes a deflection correction screw 313, a third fixing member 311 and a fourth fixing member 312 arranged on the second mounting plate 42.

[0046] refer to Figure 2 , the third fixing member 311, the fourth fixing member 312 and the cylinder 15 connecting member are provided with a pin hole 16, and the correction screw 313 passes through the pin holes on the third fixing member 311 and the fourth fixing member 312, and is directly connected to the correction motor 32. The correction screw 313 is a ball screw, which can reduce the error caused by the screw clearance and has higher precision. The correction motor 32 is arranged at one end of the second mounting plate 42 and is directly connected to the correction screw 313. The correction motor 32 is a servo motor, which drives the correction screw 313 to rotate forward and reverse, and is used to accurately adjust the cutting component 10, and the correction range is ±30-50 mm.

[0047] The mounting plate includes a first mounting plate 41 and a second mounting plate 42 disposed below the first mounting plate 41. Two parallel rows of slide rails 421 are disposed on the upper surface of the second mounting plate 42, and two sliders 422 are disposed on each row of slide rails 421. The sliders 422 are fixedly connected to the first mounting plate 41 to drive the first mounting plate 41 to move on the slide rails 421. A guide rail 411 is disposed on the upper surface of the first mounting plate 41, and two guide sliders 412 are disposed on the guide rail 411. The two guide sliders 412 are respectively fixedly connected to the two cutting blade brackets 13, and the cutting assembly 10 can perform reciprocating translational motion along the guide rails 411.

[0048] The cutting roller 50 is in contact with the cutting assembly 10 and is used to fix the transition layer 60. The cutting roller 50 can perform a rotary motion to transport the transition layer 60 on the surface of the cutting roller 50 and cooperate with the abutting cutter to cut the transition layer 60. This prevents the material from moving or loosening during the cutting process, thereby ensuring cutting accuracy and safety.

[0049] The cutting mechanism also includes a feedback control system (not shown), which controls the width adjustment motor 21 and the deviation correction motor 32 to make adjustments by receiving data fed back by the width measurement sensor 23 .

[0050] In an embodiment not shown, when the data fed back by the width measuring sensor 23 exceeds the deviation range set by the feedback control system, the system drives the width adjustment motor 21 and the deviation correction motor 32 to adjust the width adjustment component 20 and the deviation correction component 30, thereby controlling the cutting component 10 to make corresponding adjustments to the precise position and width.

[0051] In a specific embodiment, the cutting mechanism of the tire transition layer 60 works as follows: the range of the width sensor 23 is set to 5 to 25 mm, and the deviation is set to -1 to 1 mm. After the transition layer 60 is extruded by the calendering mechanism, it passes through the cutting roller 50, and the width adjustment motor 21 is accurately positioned. The synchronous belt 224 connected to the width adjustment motor 21 drives the width adjustment screw 221 to move, and further drives the cutting assembly 10 to reciprocate on the guide rail 411. After determining the specific position, the cutting assembly 10 adjusts the angle, and the disc knife 11 is driven by the cylinder 15 to descend to the transition layer 60 for cutting. During the cutting process, when the data fed back by the width sensor 23 exceeds the deviation, the feedback control system drives the deviation correction motor 32 to make corresponding adjustments.

[0052] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
