[0040] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0041] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment of the present invention, a waste automobile tire cutting machine is disclosed, used to cut the sidewall of a waste tire 3, the cutting point being between the inner and outer rings of the tire 3 sidewall, comprising,

[0042] The first cutting machine body 2 includes a first outer expansion chuck 15 with a plurality of first outer expansion blocks 14. The first outer expansion chuck 15 is configured to be rotatable. The plurality of first outer expansion blocks 14 are evenly distributed around the center of the first outer expansion chuck 15 and can move radially along the first outer expansion chuck 15. The plurality of first outer expansion blocks 14 are used to extend into the inner ring of the tire 3 to be cut from one side. When the plurality of first outer expansion blocks 14 move radially outward along the first outer expansion chuck 15, the tire 3 to be cut can be tightened so that the tire 3 to be cut and the first outer expansion chuck 15 are fixed together and the two rotate synchronously.

[0043] The second cutting machine body 4 includes a second outer expansion chuck 24 with multiple second outer expansion blocks 25. The second outer expansion chuck 24 is rotatable. The multiple second outer expansion blocks 25 are evenly distributed around the center of the second outer expansion chuck 24 and can move radially along the second outer expansion chuck 24. The multiple second outer expansion blocks 25 are used to penetrate into the inner ring of the tire 3 from the side opposite to the first outer expansion chuck 15. When the multiple second outer expansion blocks 25 move radially outward along the second outer expansion chuck 24, they can tighten the tire 3 to be cut so that the tire 3 to be cut and the second outer expansion chuck 24 are fixed together and the two rotate synchronously. The structure and working principle of the second outer expansion chuck 24 are the same as those of the first outer expansion chuck 15, and will not be described again.

[0044] The saw blade feed device 5 / 52 is used to precisely control the saw blade feed direction, angle and speed so that the saw blade can automatically cut the tire, which greatly reduces the workload.

[0045] The first external expansion chuck 15 and the second external expansion chuck 24 extend horizontally along their axes and are positioned opposite each other. The saw blade can cut the tire 3 from both sides. One of the first external expansion chuck 15 and the second external expansion chuck 24 is configured to be able to move closer to or further away from the other. When the first external expansion chuck 15 and the second external expansion chuck 24 are close to each other, they can clamp the tire 3 together, improving the stability of the tire 3 and facilitating cutting; conversely, the tire 3 can be released.

[0046] Furthermore, the first expansion chuck 15 is configured as a common jaw chuck, which includes four jaws, a chuck body, and a transmission mechanism, a drive mechanism, a connecting plate, etc., disposed inside the chuck body to realize the synchronous movement and opening and closing of the four jaws. Specifically, the four first expansion blocks 14 are respectively connected to the four jaws, and the chuck body is also provided with four expansion block guide grooves 37. The four expansion block guide grooves 37 are evenly distributed and extend radially along the chuck body. The four first expansion blocks 14 can move precisely along the four expansion block guide grooves 37 respectively. When the four first expansion blocks 14 penetrate into the inner ring of the tire 3, the drive mechanism drives the four first expansion blocks 14 to expand outward synchronously, automatically tightening the tire 3. The second expansion chuck 24 is also configured as a common jaw chuck, which will not be described in detail.

[0047] Furthermore, the diameters of the first outer expansion chuck 15 and the second outer expansion chuck 24 are both smaller than the outer diameter of the tire. When the first outer expansion chuck 15 and the second outer expansion chuck 24 clamp the tire, the outer ring of the tire can be located outside the first outer expansion chuck 15 and the second outer expansion chuck 24 so that the saw blade can contact the cutting point of the tire.

[0048] Reference Figure 1 , Figure 11 and Figure 12 As shown, in order to automatically lift the tire 3 to be cut into the gap between the first outer expansion chuck 15 and the second outer expansion chuck 24 so that the first outer expansion block 14 and the second outer expansion block 25 can extend into the inner ring of the tire 3, a tire lifting frame 1 is also included, which is provided with a first driver 9, a support plate 8, and a plurality of round tubes 6. The round tubes 6 are preferably steel pipes, and the first driver 9 is preferably a hydraulic cylinder. The plurality of round tubes 6 extend horizontally and are linearly arranged on the support plate 8, and adjacent round tubes 6 are spaced apart. The tire 3 is placed on the round tubes 6, and the smooth arc of the round tubes 6 can help the tire 3 to be automatically adjusted to be placed in the center. In another embodiment, the plurality of round tubes 6 are arranged in an arc shape on the pallet 8, and the multiple round tubes 6 fully support the tire 3 from the bottom and sides to prevent the tire 3 from rolling off when it is raised or lowered; the first driver 9 is used to drive the pallet 8 to rise or fall. When the first external expansion chuck 15 and the second external expansion chuck 24 are arranged opposite each other in the horizontal direction, the tire lifting frame 1 is arranged below the gap between the first external expansion chuck 15 and the second external expansion chuck 24. The tire lifting frame 1 can lift the vertically placed tire 3 between the first external expansion chuck 15 and the second external expansion chuck 24.

[0049] Furthermore, in this embodiment, two horizontally spaced circular tubes 6 are included, and the two circular tubes 6 are fixed above the support plate 8 by support blocks 7, so that the two adjacent circular tubes 6 and the center of the tire 3 form a stable triangle, thereby improving the stability of the tire 3.

[0050] Reference Figure 4 and Figure 6 As shown, the first cutting machine body 2 further includes a first base 10 and a first driver 9 and a first transmission mechanism disposed on the first base 10. The first transmission mechanism includes a first bearing seat 13, a first bearing disposed on the first bearing seat 13, a first outer expansion chuck shaft 12, a first driven pulley 19, a first driving pulley 17, and a first V-shaped transmission belt 18, etc. The first outer expansion chuck 15 is rotatably connected to the first base 10. Specifically, the first outer expansion chuck 15 is connected to the first bearing through the first outer expansion chuck shaft 12. The first driver 9 is preferably a motor. The first driver 9 is used to drive the first outer expansion chuck 15 to rotate, so as to realize the automatic rotation of the tire 3. Specifically, the output end of the first outer expansion chuck 15 is connected to the first driving pulley 17, the first outer expansion chuck shaft 12 is connected to the first driven pulley 19, and the first driven pulley 19 and the first driving pulley 17 are driven by the first V-shaped transmission belt 18.

[0051] Reference Figure 4 and Figure 6As shown, the second cutting machine body 4 further includes a second base 32, a third driver 36 disposed on the second base 32, and a second transmission mechanism. The second transmission mechanism includes a second bearing seat 26, a second bearing disposed on the second bearing seat 26, a second outer expansion chuck shaft 27, a second driven pulley 33, a second driving pulley 35, and a second V-shaped transmission belt 34, etc. The second transmission mechanism has the same structure and principle as the first transmission mechanism, and will not be described again. The second outer expansion chuck 24 is rotatably connected to the second base 32 through the second bearing and the second outer expansion chuck shaft 27. The third driver 36 is preferably a motor. The third driver 36 is used to drive the second outer expansion chuck 24 to rotate, so as to realize the automatic rotation of the tire 3.

[0052] Furthermore, the first cutting machine body 2 also includes an intermediate support 11 fixedly mounted on the first base 10, and the second driver 16, the first driver 9 and the first transmission mechanism are all mounted on the intermediate support 11.

[0053] Reference Figure 1 , Figure 7 and Figure 8 As shown, the second cutting machine body 4 also includes a guide post 23 and a guide wheel assembly 21. The guide post 23 has a circular cross-section and extends along the moving direction of the second external expansion chuck 24. The guide wheel assembly 21 includes a guide wheel bracket and a first guide wheel 48 and a second guide wheel 43 rotatably connected to the guide wheel bracket. When the guide post 23 extends horizontally, the second guide wheel 43 and the first guide wheel 48 are respectively rolled and connected to the upper and lower sides of the guide post 23. It can be understood that the guide post 23 passes through the gap between the second guide wheel 43 and the first guide wheel 48. Therefore, the guide wheel assembly 21 can move smoothly along the guide post 23. The second external expansion chuck 24 and the third driver 36 are both fixedly mounted on the guide wheel bracket. Therefore, the second external expansion chuck 24 can accurately approach the first external expansion chuck 15 along the guide post 23.

[0054] Reference Figure 5 As shown, further, in order to use the second external expansion chuck 24 to press the tire 3, the second cutting machine body 4 also includes a fourth driver 30 disposed on the second base 32. The fourth driver 30 is preferably a hydraulic cylinder. The fourth driver 30 drives the guide wheel bracket to move along the guide post 23. When the fourth driver 30 pushes the guide wheel bracket to the left, the second external expansion chuck 24 can press the side of the tire 3; otherwise, the second external expansion chuck 24 releases the tire 3.

[0055] Reference Figure 7As shown, further, in order to stably support the second expansion chuck 24 and the third driver 36, two guide posts 23 and four guide wheel assemblies 21 distributed along the length of the guide posts 23 are included. The two guide posts 23 are distributed on both sides of the second base 32 and the axes of the multiple guide posts do not coincide. The four guide wheel assemblies 21 are evenly distributed on both sides of the second base 32, and the four guide wheel assemblies 21 together support the second expansion chuck 24 and the third driver 36.

[0056] Reference Figure 8 As shown, further, in order to adjust the height of the first guide wheel 48 up and down and change the friction between the first guide wheel 48 and the guide post 23, the guide wheel bracket is provided with a strip-shaped hole 39 extending in the vertical direction and a screw hole 49 passing through the strip-shaped hole 39. The rotation shaft 38 of the first guide wheel 48 located below the guide post 23 passes through the strip-shaped hole 39. The strip-shaped hole 39 provides a margin for the rotation shaft 38 to be finely adjusted up and down. The screw 47 is threadedly connected to the guide wheel bracket through the screw hole 50, and the threaded rods of the two screws abut against the two ends of the rotation shaft 38 in the vertical direction. When the screws are rotated, the threaded rods can push the rotation shaft 38 to change the gap between the first guide wheel 48 and the guide post 23, thereby changing the friction between the two.

[0057] Reference Figure 2 As shown, the first pair of cutting machine body 2 also includes a saw blade feeding device 5, and the second pair of cutting machine body 4 also includes a saw blade feeding device 52. The two saw blade feeding devices 5 / 52 are symmetrically arranged on the first base 10 and the guide wheel bracket, respectively. The saw blades of the two saw blade feeding devices are arranged on both sides of the tire 3, which can simultaneously cut the tire 3 on both sides, greatly improving the cutting efficiency of the tire 3 and reducing the workload of the operator.

[0058] Reference Figure 8 As shown, further, in order to ensure that the first guide wheel and the second guide wheel can move accurately along the guide post 23, the surfaces of the first guide wheel and the second guide wheel are provided with arc-shaped grooves 51 extending in their circumference; the guide wheel matches the guide post 23 through the arc-shaped grooves 51 to achieve the purpose of rolling connection with the guide post 23.

[0059] Furthermore, the diameter of the arc-shaped groove 51 is larger than the diameter of the guide post 23, ensuring that the bottom of the arc-shaped groove 51 of the guide wheel is in effective contact with the arc of the guide post 23.

[0060] Reference Figure 9 and Figure 10As shown, the guide wheel bracket further includes a first support member 40 and a second support member 45 facing each other, and a support plate 44 fixedly connected to the first support member 40 and the second support member 45. The second external expansion chuck 24 and the third driver 36 are both fixedly connected to the support plate 44. The first guide wheel 48 and the second guide wheel 43 are both disposed between the first support member 40 and the second support member 45. The two ends of the rotation shaft 38 of the first guide wheel 48 are rotatably connected to the first support member 40 and the second support member 45, respectively. Specifically, the first support member 40 and the second support member 45 are respectively provided with strip holes 39 / 46. The two ends of the rotation shaft 38 of the first guide wheel 48 pass through the strip holes 39 / 46, respectively. The first support member 40 and the second support member 45 can limit the first guide wheel 48 and the second guide wheel 43 to prevent them from deviating. Similarly, the two ends of the rotation shaft 41 of the second guide wheel 43 are rotatably connected to the first support member 40 and the second support member 45, respectively.

[0061] Reference Figure 9 As shown, the support plate 44 is located at the top of the first support member 40 and the second support member 45, and is used to support the second external expansion chuck 24 and the third driver 36; the screw hole is located at the bottom of the first support member 40 and the second support member 45, which facilitates the operator to fine-tune the screw.

[0062] Reference Figure 4 and Figure 5 As shown, the second pair-cutting machine body 4 also includes a machine body platform 29, and the lower side of the machine body platform 29 is fixedly connected to the support plate 44 of the four guide wheel assemblies 21; the second external expansion chuck 24, the third driver 36, and the saw blade feeding device are all connected to the upper side of the machine body platform 29; the first pair-cutting machine body 2 also includes a machine body platform 20 fixedly connected to the intermediate support base 11, and the first external expansion chuck 15, the first external expansion chuck 15, and the saw blade feeding device 52 are all connected to the upper side of the machine body platform 20.

[0063] Reference Figure 5 As shown, the second pair of cutting bodies 4 further includes a pusher 28 fixedly connected to the lower side of the body platform 29. The pusher 28 is connected to the output end of the fourth driver 30, and the fourth driver 30 indirectly pushes the body platform 29 to move by pushing the pusher 28.

[0064] Reference Figure 5 As shown, the upper side of the body platform 29 is further provided with two guide post support members 22 for supporting the two ends of the guide post 23 respectively.

[0065] Reference Figure 5As shown, the second base 32 is further provided with a driver bracket 31 for supporting the fourth driver 30.

[0066] Furthermore, the first expansion chuck 15 and the second expansion chuck 24 rotate synchronously or independently.

[0067] Furthermore, it also includes a synchronous starting device and a separate starting device. The synchronous starting device is used to control the first external expansion chuck 15 and the third driver 36 to start synchronously, so as to control the first external expansion chuck 15 and the second external expansion chuck 24 to rotate synchronously. The separate starting device is used to control the first external expansion chuck 15 and the third driver 36 to start separately, so as to control the first external expansion chuck 15 and the second external expansion chuck 24 to rotate separately.

[0068] In one embodiment of the present invention, the first external expansion chuck 15 and the second external expansion chuck 24 extend axially in the vertical direction, and the first external expansion chuck 15 and the second external expansion chuck 24 are arranged facing each other vertically, and the saw blade cuts the tire 3 from both the upper and lower sides.

[0069] Furthermore, when the first external expansion chuck 15 and the second external expansion chuck 24 are arranged facing each other in the vertical direction, the tire lifting frame 1 is arranged facing the gap between the first external expansion chuck 15 and the second external expansion chuck 24, and the tire lifting frame 1 can move the horizontally placed tire 3 horizontally to the gap between the first external expansion chuck 15 and the second external expansion chuck 24.

[0070] In one embodiment of the present invention, the first cutting machine body 2 further includes a guide post 23 and a guide wheel assembly 21. The guide post 23 extends along the moving direction of the first external expansion chuck 15. The guide wheel assembly 21 includes a guide wheel bracket and a first guide wheel 48 and a second guide wheel 43 rotatably connected to the guide wheel bracket. The first guide wheel 48 and the second guide wheel 43 are respectively rolled on both sides of the guide post 23. The first external expansion chuck 15 and the second driver 16 are disposed on the guide wheel bracket. Therefore, the first external expansion chuck 15 can accurately approach the second external expansion chuck 24 along the guide post 23.

[0071] In one embodiment of the present invention, in order to use the first external expansion chuck 15 to press the tire 3, the first cutting machine body 2 further includes a fourth driver 30 disposed on the first base 10. The fourth driver 30 is preferably a hydraulic cylinder. The fourth driver 30 drives the guide wheel bracket to move along the guide post 23. When the fourth driver 30 pushes the guide wheel bracket to the right, the first external expansion chuck 15 can press the side of the tire 3; otherwise, the first external expansion chuck 15 releases the tire 3.

[0072] The working principle of the waste automobile tire cutting machine described in this invention is as follows:

[0073] The operator first places the tire to be cut 3 vertically on the two round tubes 6 of the tire lifting frame 1. After the tire 3 is aligned, the first drive 9 raises the tire 3 until the center of the tire 3 is aligned with the center of the first outer expansion chuck 15. The operator then moves the tire 3 towards the first outer expansion chuck 15, causing the four first outer expansion blocks 14 to extend into the inner ring of the tire 3. Next, the four first outer expansion blocks 14 move towards the outer ring of the tire 3, tightening the tire 3. The tire lifting frame 1 then lowers, and subsequently the third drive 36 pushes the pusher 28 to move, causing the machine platform 29 to move to the left until the second outer expansion chuck 24 engages. After touching the side of the tire 3 to be cut, the pushing stops. At this time, the four second outer expansion blocks 25 have been inserted into the inner ring of the tire 3 to be cut. Then, the four second outer expansion blocks 25 move to the outer ring of the tire 3, tightening the tire 3. Then, the third drive 36 continues to push the machine platform 29 to the left until the second outer expansion chuck 24 presses the tire 3. Then, the second drive 16 and the third drive 36 drive the first outer expansion chuck 15 and the second outer expansion chuck 24 to rotate simultaneously, causing the tire 3 to rotate. Finally, the two saw blade feed devices 5 / 52 extend the saw blades, and the two saw blades begin to rotate and cut the tire 3 from both sides simultaneously.

[0074] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation.
