[0002] The production of tires needs to go through the processes of mixing, preparation of rubber components, forming of rubber components, vulcanization, and inspection and testing in sequence, and finally the finished tires are obtained. Among them, the preparation process of rubber components includes 6 main sections, namely: extrusion, calendering, bead forming, cord cutting, sticking triangular rubber strips, and belt layer forming. Among them, the cord cutting machine is one of the important equipment on the tire production line. Its main function is to cut the steel cord into cord strips according to the set angle and width, and then splice, edge-wrap and edge-paste, and wind the cord strips to obtain the semi-finished product for the tire forming machine to produce - the belt layer. The cutting effect of the cord directly affects the quality of the finished tire and is an important link in the tire production and processing process.

[0003] During the production and processing of tires, it is often necessary to produce various specifications of tires, so the cutting angle needs to be adjusted. However, at present, most of the existing cord cutting devices adopt the mode of manual angle adjustment by workers during use. This mode cannot quickly and accurately adjust the cutting angle of the cord, thus seriously reducing the cutting efficiency of the tire cord.

[0004] Therefore, a cord cutting device for tire processing is proposed. Content of the Utility Model

[0046] As Figure 1 , Figure 4 shown, a cord cutting device for tire processing includes: a support frame 1, a cutting assembly, and a cutting conveyor belt 3;

[0047] The center position of the cross beam connected to the top of the support frame 1 is rotationally connected to the cutting assembly through a first rotating shaft 8. Below the cutting assembly, a cutting conveyor belt 3 is arranged inside the support frame 1, and cutting support plates 22 are arranged at the left and right ends of the cutting conveyor belt 3;

[0048] A decelerating swing motor 9 is provided at the top of the support frame 1. The output shaft of the decelerating swing motor 9 is rotatably connected to the top of the fixed frame 201 through the second rotating shaft 10. The angle of the fixed frame 201 can be adjusted by controlling the opening and closing of the decelerating swing motor 9, and then the angle of the cutting knife 207 can be adjusted, so as to meet the cutting requirements of tire cord fabrics of different specifications.

[0049] The central positions of the left and right support columns of the support frame 1 are connected by a support link 4. A second air cylinder 5 is arranged inside the support link 4. The piston end of the second air cylinder 5 is fixedly connected with a connecting frame 6. A pressing plate 7 is fixedly arranged at the bottom of the connecting frame 6, which is used to press the cord fabric to prevent the cord fabric from tilting and shifting during the cutting process, and can also prevent the cord fabric from separating from the cutting conveyor belt 3 as the cutting knife 207 rises after the cord fabric is cut off. A rubber gasket is arranged at the bottom of the pressing plate 7, which can effectively protect the cord fabric on the cutting conveyor belt 3 and prevent the cord fabric from being damaged by the impact of the downward pressure of the pressing plate 7.

[0050] A dial 12 is arranged at the central position of the top cross beam of the support frame 1. A pointer 13 is arranged inside the dial 12. The pointer 13 is fixedly connected to the upper end of the first rotating shaft 8 and points in the same direction as the length direction of the fixed frame 201. The pointer 13 can rotate inside the dial 12 as the cutting assembly rotates, which is convenient for the user to accurately adjust the rotation angle of the cutting assembly.

[0051] A stacking assembly is arranged in front of the cutting conveyor belt 3. The stacking assembly includes a stacking conveyor belt 23. A stacking support plate 24 is arranged at the bottom of the stacking conveyor belt 23. A number of stacking partitions 25 are arranged on the stacking conveyor belt 23. A stacking motor 18 is arranged on the outer side of the upper front end of the left cutting support plate 22. The output shaft of the stacking motor 18 passes through the left cutting support plate 22 and is connected to the second rotating shaft 19. A rotating roller 20 is fixedly sleeved on the second rotating shaft 19. A third air cylinder 16 is arranged inside the front support link 4. The piston end of the third air cylinder 16 is connected with a calibration baffle 17. A counting sensor 21 is arranged at the bottom of the front support link 4. When the third air cylinder 16 is started, it drives the calibration baffle 17 to move downward to calibrate the position of the cut cord fabric. At the same time, the counting sensor 21 can perform real-time counting. After the calibration is completed, the second air cylinder 16 is reversed to drive the calibration baffle 17 to move upward, so that the cord fabric continues to move forward and falls between two adjacent stacking partitions 25 on the stacking conveyor belt 23 through the gap between the rotating roller 20 and the stacking conveyor belt 23. When the counting sensor 21 senses that the number of cord fabrics reaches the set value, it will transmit a signal to the stacking conveyor belt 23 to make the stacking conveyor belt 23 move and drive the stacking partitions 25 to move, thus realizing the automatic counting, stacking and transmission of the cord fabric.

[0052] The upper part of the left support frame 1 is equipped with a control panel 15, which can control components such as the first cylinder 202 and the decelerating swing motor 9 to ensure the smooth progress of the cutting process.

[0053] As Figure 2-3 shown, the cutting assembly includes a fixed frame 201. The top plate of the fixed frame 201 is fixedly connected to the first rotating shaft 8. On the upper surface of the bottom plate of the fixed frame 201, a first cylinder 202 is provided. The piston end of the first cylinder 202 passes through the bottom plate of the fixed frame 201 and is fixedly connected to the lifting frame 203. Thus, the lifting control of the lifting frame 203 can be realized through the first cylinder 202. On both sides of the bottom of the fixed frame 201, telescopic rods 14 are respectively provided. The lower ends of the telescopic rods 14 are fixedly connected to the top of the lifting frame 203, which can realize the stable lifting of the lifting frame 203. On the outside of the left side of the lifting frame 203, a cutting motor 204 is fixedly provided. The output shaft of the cutting motor 204 passes through the left side plate of the lifting frame 203 and is fixedly connected to a cutting lead screw 205 arranged inside the lifting frame 203. A cutting slider 206 is sleeved on the cutting lead screw 205. The cutting slider 206 is threadedly connected to the cutting lead screw 205. A cutting knife 207 is fixedly provided at the bottom of the cutting slider 206. When the cutting motor 204 is started, it drives the cutting lead screw 205 to rotate, and then drives the cutting slider 206 thereon to move, so that the cutting knife 207 at the bottom of the cutting slider 206 moves to cut the curtain cloth on the cutting conveyor belt 3.

[0054] As Figure 5 shown, an angle limit component is provided at the top of the support frame 1. The angle limit component includes a sliding plate 1101, a sliding cavity 1102, a sliding column 1103, and a locking handle 1104. The sliding plate 1101 is fixedly provided at the top of the support frame 1. A sliding cavity 1102 is opened inside the sliding plate 1101. A sliding column 1103 is slidably arranged inside the sliding cavity 1102. The bottom end of the sliding column 1103 is fixedly provided at the top of the fixed frame 201. A locking handle 1104 is provided at the upper end of the sliding column, which can fix the position of the cutting assembly after the angle adjustment of the cutting assembly is completed, avoid the deviation of the cutting device during the cutting process, and ensure a good cutting effect.

[0055] Working principle of the utility model: First, when the curtain fabric on the cutting conveyor belt 3 moves to the lower part of the cutting assembly, the cutting conveyor belt 3 stops moving. The second cylinder 5 is started to drive the pressing plate 7 to move downward until the curtain fabric is pressed tightly. Then, the decelerating swing motor 9 is started to drive the cutting assembly to rotate, and further drive the sliding column 1103 to slide in the sliding cavity 1102. At the same time, the pointer 13 rotates in the scale 12 along with the rotation of the cutting assembly. After rotating to the required angle, the decelerating swing motor 9 is turned off to stop the rotation of the cutting assembly, and then the locking handle 1104 is tightened to fix the cutting assembly. Then, the first cylinder 202 is started to drive the lifting frame 203 to move downward. When the cutting knife 207 contacts the cutting conveyor belt 4, the cutting motor 204 is started to drive the cutting lead screw 205 to rotate, and further drive the cutting slider 206 to slide inside the lifting frame 203, so that the cutting knife 207 transversely cuts the curtain fabric on the cutting conveyor belt 3. After the curtain fabric is cut, the second cylinder 5 is reversed to drive the pressing plate 7 to move upward to release the fixation of the curtain fabric. The cutting conveyor belt 3 continues to move to drive the curtain fabric to move to the calibration baffle 17. The third cylinder 16 is started to drive the calibration baffle 17 to move downward to calibrate the position of the cut curtain fabric. At the same time, the counting sensor 21 can perform real-time counting. After calibration, the second cylinder 16 is reversed to drive the calibration baffle 17 to move upward. The curtain fabric continues to move forward and falls between two adjacent stacking partitions 25 on the stacking conveyor belt 23 through the gap between the rotating roller 20 and the stacking conveyor belt 23. When the counting sensor 21 senses that the number of curtain fabrics reaches the set value, a signal will be transmitted to the stacking conveyor belt 23 to make the stacking conveyor belt 23 move and drive the stacking partitions 25 to move, realizing the automatic counting stacking and transmission of the cut curtain fabric.

[0056] Certainly, the above description is not a limitation to the utility model, and the utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the substantial scope of the utility model should also fall within the protection scope of the utility model.
