Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] A device for cutting waste rubber tires into strips has a structure as Figures 1-3 shown, including a support frame 1. A strip cutting box 2 is arranged at the top of the support frame 1. A collection box 3 communicating with the strip cutting box 2 is arranged at the bottom of the support frame 1. A telescopic column 8 is arranged on the top of the support frame 1 on one side of the strip cutting box 2. One side of the top of the telescopic column 8 is provided with a mounting plate 9. An expansion support device is arranged on the mounting plate 9. A slide rail 13 is arranged on the upper part of the strip cutting box 2 away from the telescopic column 8. An expansion driving device is installed on the slide rail 13 through a slider 14. A strip cutting roller 5 is arranged inside the strip cutting box 2. A cutting knife 7 is arranged in the middle of the upper end of the strip cutting box 2.

[0026] When the tire needs to be cut, the operator places the tire on the telescopic support device. By starting the telescopic support device, the tire can be supported and fixed. Then, the telescopic column 8 drives the tire on the telescopic support device to move towards the cutting strip box 2. The bottom of the tire can contact the cutting knife 7, and the telescopic column 8 continues to work until the tire is cut off by the cutting knife 7;

[0027] The telescopic driving device moves towards the outer side of the tire through the cooperation of the slider 14 and the slide rail 13 until the telescopic driving device abuts against the outer side of the tire. The telescopic driving device can drive the tire to rotate, and the cut end of the tire will move along the side of the cutting knife 7 towards the cutting strip roller 5. The cutting strip work of the tire is realized through the rotation of the cutting strip roller 5. Due to the setting of the telescopic support device, tires of different sizes can be effectively fixed, improving the adaptability of this device;

[0028] The tire cut into strips will fall into the collection box 3 at the bottom of the cutting strip box 2. The bottom of the collection box 3 is provided with rollers 4, which is convenient for moving the collection box 3 out from the bottom of the support frame 1 through the rollers 4 when the collection box 3 is full, and then putting a new collection box 3 for collection work.

[0029] The telescopic support device includes a cross-shaped sliding track 10 installed on the mounting plate 9. The sliding track 10 is respectively provided with sliding seats 11 that can move in four directions. The sliding seats 11 are installed with support rods 12, and the support rods 12 are located at the top of the cutting strip box 2.

[0030] When the operator installs the tire on the support rod 12, the sliding seat 11 drives the support rod 12 to move on the sliding track 10 until all four support rods 12 can effectively abut against the inner side of the tire, ensuring that the support rods 12 effectively fix the tire. Since the sizes and models of the tires are different and the inner diameters of the tires are different, the movement of the support rod 12 driven by the sliding seat 11 can ensure that this device can effectively fix tires of different sizes and models, improving the practicability of this device.

[0031] The telescopic driving device includes a telescopic rod 15. The telescopic rod 15 is installed on the slider 14. One side of the top of the telescopic rod 15 facing the support column is provided with a driving roller 16, and the side of the top of the telescopic rod 15 opposite to the driving roller 16 is provided with a second motor 17 for driving the driving roller 16 to rotate.

[0032] When the tire is cut, the slider 14 and the slide rail 13 cooperate with each other to drive the driving roller 16 on the support column to move towards the outer side of the tire until the driving roller 16 abuts against the outer side of the tire. Driven by the second motor 17, the driving roller 16 can drive the end of the cut tire to move along the side of the cutting knife 7 towards the cutting strip roller 5 to complete the cutting strip work. Since the sizes and specifications of the tires are different, by setting the telescopic rod 15, the driving roller 16 can be driven to move up and down in position to ensure that the driving roller 16 and the closest support rod 12 are at the same horizontal height. When the driving roller 16 contacts the tire, the driving roller 16 can cooperate with the support rod 12 to form a clamping force on the tire, ensuring effective driving of the tire towards the cutting strip roller 5 and further improving the practicability of the device.

[0033] The support rod 12 is rotatably connected to the sliding seat 11, and a power source for its movement is arranged inside the sliding seat 11.

[0034] Driven by the power source, the support rod 12 on the sliding seat 11 can be effectively contracted and extended to ensure that the device can effectively fix tires of different sizes. The rotatably arranged support rod 12 can ensure that when the driving roller 16 cooperates with the corresponding support rod 12 to clamp the tire, the support rod 12 can rotate effectively, reducing the frictional force of the support rod 12 on the inner side of the tire while ensuring effective clamping and ensuring effective driving of the tire.

[0035] The cutting strip roller 5 includes two, and cutting teeth are arranged on both of the two cutting strip rollers 5. The cutting teeth on the two cutting strip rollers 5 abut against each other, and a first motor 6 for the rotation of the cutting strip roller 5 is arranged outside the cutting strip box 2.

[0036] A plurality of cutting teeth are arranged in an array on the cutting strip roller 5. Driven by the first motor 6, the two cutting strip rollers 5 can rotate relatively to cut the tire in contact with the cutting strip roller 5 into strips. While the cutting strip roller 5 rotates to cut the tire into strips, the rotation of the cutting strip roller 5 can drag the tire to continuously move towards the cutting strip roller 5 to perform the cutting strip work on the tire.

[0037] The cutting knife 7 is arranged on the cutting strip box 2 above the two cutting strip rollers 5. The horizontal height of the top of the cutting knife 7 is higher than the horizontal height of the top of the cutting strip box 2, and the horizontal height of the bottom of the cutting knife 7 is lower than the horizontal height of the top of the cutting strip roller 5 and higher than the horizontal height of the abutting position of the two cutting strip rollers 5.

[0038] When the tire follows the telescopic column 8 to descend, it is convenient to contact the cutting edge of the cutting knife 7 first, so as to cut the tire first. Then, driven by the driving roller 16, the cut port of the tire moves along the side of the cutting knife 7 towards the position where it abuts against the cutting strip roller 5, facilitating the cutting strip roller 5 to effectively cut the tire into strips.

[0039] Embodiment 2

[0040] On the basis of Embodiment 1, teeth are arranged in an array on the surface of the driving roller 16.

[0041] Since this device cuts the waste tires into strips, due to wear on the outer wall of the waste tires, after the driving roller 16 abuts against the outer wall of the tire, the rotation of the driving roller 16 may not ensure effective driving of the tire to move. To further improve the driving efficiency of the driving roller 16, teeth are provided on the surface of the driving roller 16. The teeth of the driving roller 16 can abut against the outer wall of the tire, further improving the driving efficiency of the driving roller 16 and ensuring the working efficiency of the strip cutting of this device.

[0042] As mentioned above, the above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes, increases or decreases, or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
