[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Referring to Figure 1 , Figure 3 , Figure 4 , an embodiment provided by the present invention: a waste tire cutting machine, including a bracket 1, which mainly realizes the cutting function of waste tires through the cooperation of multiple components. Its core structure includes the bracket 1. This bracket 1 serves as the basic support part of the entire device, providing a stable installation platform for other components. Inside the bracket 1, a driving component is fixedly connected. The driving component is the power source for the operation of the device. Inside the driving component, a second rotating rod 6 is rotatably connected. The second rotating rod 6 plays a key role in the transmission process of the entire cutting action. On the left side of the outside of the second rotating rod 6, a driven wheel 7 is fixedly connected. The driven wheel 7 is connected to the driving wheel 4 through a belt 8. This transmission method can effectively transmit the power from the driving wheel 4 to the driven wheel 7, thereby driving the second rotating rod 6 to rotate. On the right side of the outside of the second rotating rod 6, a cutting knife 9 is fixedly connected. The cutting knife 9 is the component that directly cuts the waste tire, and its quality and sharpness directly affect the cutting effect.

[0032] On the top of the bracket 1, a support frame 10 is fixedly connected. The support frame 10 provides additional support for other related components of the device. Inside the support frame 10, a support column 11 is fixedly connected. The support column 11 plays a role in stabilizing the structure, ensuring the stability of the device during operation. On the left and right sides of the outside of the support column 11, rotating wheels 12 are rotatably connected. The rotating wheels 12 can rotate flexibly on the support column 11. This rotating characteristic provides convenience for the subsequent fixing and conveying of waste tires. Inside each of the rotating wheels 12, a plurality of sliding plates 13 are slidably connected. The sliding plates 13 can slide inside the rotating wheels 12, realizing a flexible adjustment mechanism. On the adjacent sides of the plurality of sliding plates 13, a plurality of first springs 14 are fixedly connected. The first springs 14 are the key elements for fixing waste tires of different thicknesses. When the waste tire enters the device, the first springs 14 will automatically adjust according to the thickness of the waste tire, compressing or stretching to adapt to different situations. On the opposite sides of the plurality of sliding plates 13, a plurality of pressing heads 15 are fixedly connected. The pressing heads 15 are in direct contact with the waste tire and apply appropriate pressure to the waste tire under the action of the first springs 14, thereby achieving fixation.

[0033] Meanwhile, fixed blocks 16 are fixedly connected to both the left and right sides of the top of the bracket 1. The fixed blocks 16 provide installation positions and support for other key components of the device. An inner cavity 17 is formed inside the fixed block 16, which provides a accommodation space for the disassembly component. A disassembly component for installation is fixedly connected to the rear inner wall of the inner cavity 17. The design of the disassembly component facilitates the maintenance and replacement of the cutting tool.

[0034] Referring to Figure 1 , Figure 2 , the drive assembly includes a motor 2. As the power core of the device, the motor 2 is firmly fixedly connected to the inside of the bracket 1 at its bottom to ensure that there is no displacement during operation. A rotating rod 3 is fixedly connected to the drive end of the motor 2. The rotating rod 3 rotates under the drive of the motor 2 to transmit the rotational power of the motor 2. A driving wheel 4 is fixedly connected to the outside of the rotating rod 3. The driving wheel 4 is closely matched with the belt 8. When the rotating rod 3 rotates, the driving wheel 4 rotates synchronously to drive the belt 8 to move. A housing 5 is fixedly connected to the left side of the bracket 1. The housing 5 plays a role in protecting the internal components and preventing external factors from interfering with components such as the rotating rod. The left side of the outside of the rotating rod 6 is rotatably connected to the inside of the housing 5. The housing 5 provides a stable environment for the rotation of the rotating rod 6.

[0035] Referring to Figure, Figure 5 , the disassembly component includes a support plate 18, which provides a stable basic structure for the entire disassembly component. A support rod 19 is fixedly connected to the outside of the support plate 18. The support rod 19 is an installation support component for other related components. Spring two 20 is sleeved on both the left and right sides of the outside of the support rod 19. Spring two 20 plays an important reset role during the disassembly of the cutting tool. Sliding blocks 21 are slidably connected to both the upper and lower sides of the outside of the support rod 19. The sliding blocks 21 can slide flexibly on the support rod 19. This sliding characteristic provides for a series of subsequent actions. A rotating plate 22 is rotatably connected to the front side of the sliding block 21. The rotating plate 22 realizes a special transmission method through its rotational connection with the sliding block 21. A sliding plate 23 is rotatably connected to the front sides of the two rotating plates 22. The position change of the sliding plate 23 is transmitted to the sliding block 21 through the rotating plate 22. Plug pins 24 are detachably connected to both the upper and lower sides inside the fixed block 16. The plug pins 24 play a key role in fixing the cutting tool 25. Two cutting tools 25 are detachably connected to the adjacent sides of the two fixed blocks 16. The cutting tool 25 is a key component that directly contacts and cuts the waste tire. Its quality and the stability of its installation have an important impact on the cutting effect and the service life of the device. Among them, the outside of the sliding plate 23 is slidably connected to the inside of the fixed block 16. This sliding connection method enables the sliding plate 23 to move smoothly within the fixed block 16.

[0036] The outer part of the sliding block 21 is slidably connected to the upper and lower sides inside the fixed block 16, ensuring the stable sliding of the sliding block 21 within the fixed block 16. The adjacent sides of the two second springs 20 are fixedly connected to the upper and lower sides of the support plate 18, guaranteeing the stable installation of the second springs 20. The opposite sides of the two second springs 20 are respectively fixedly connected to the inner sides of the adjacent sides of the two sliding blocks 21, enabling the second springs 20 to be closely connected to the sliding blocks 21 and play their elastic role when the sliding blocks 21 move. The outer part of the first rotating rod 3 is rotatably connected to the inside of the housing 5, ensuring the stable rotation of the first rotating rod 3 within the housing 5 without being interfered by the outside. The outer part of the second rotating rod 6 is rotatably connected to the inside of the support frame 10, ensuring the smooth rotation of the second rotating rod 6 within the support frame 10. The outer part of the pressing head 15 is slidably connected to the inside of the rotating wheel 12. This sliding connection method enables the pressing head 15 to flexibly adjust its position within the rotating wheel 12 according to the condition of the waste tire. The outer part of the pin 24 is in contact with the inside of the cutting tool 25. The cutting tool 25 is firmly fixed to the fixed block 16 through the pin 24. The cross-section of the middle section of the pin 24 is square. This special shape design helps to better cooperate with other components to achieve a stable fixing effect. Grooves are provided on both the left and right sides inside the pin 24. The design of the grooves is for engaging with the sliding block 21, thereby realizing the fixing and release of the pin 24. The outer part of the sliding block 21 is engaged with the inner wall of the groove. This engagement method ensures the fixed state of the pin 24 under normal circumstances. Only when the sliding block 21 moves, the pin 24 will be released. The cutting tool 25 is used to scrape the surface to make the tire surface smoother, enabling the cutter to operate better according to the preset size and shape during cutting. During the use of the waste tire, a large amount of impurities such as soil, sand, and oil will adhere to its surface. The scraping function of the cutting tool 25 can effectively remove these impurities.

[0037] When it is necessary to cut the waste tire, the entire device starts to operate. First, the motor 2 is started. After receiving the start signal, the motor rotor inside the motor 2 starts to rotate, driving the first rotating rod 3 fixedly connected thereto to rotate. The rotation of the first rotating rod 3 is the starting link of the entire power transmission. It smoothly transmits the rotational power of the motor 2. As the first rotating rod 3 rotates, the driving wheel 4 fixedly connected to its outer part also starts to rotate synchronously. The rotation speed of the driving wheel 4 is proportional to the rotation speed of the first rotating rod 3. Its rotation drives the belt 8 closely cooperating with it to start moving. Driven by the driving wheel 4, the belt 8 moves in a circular motion around the driving wheel 4 and the driven wheel 7 at a certain speed and tension. Driven by the belt 8, the driven wheel 7 starts to rotate. The rotation of the driven wheel 7 drives the second rotating rod 6 fixedly connected thereto to rotate. The rotation speed and direction of the second rotating rod 6 are the same as those of the driven wheel 7. Its rotation drives the cutting knife 9 fixedly connected to the right side of its outer part to rotate. The cutting knife 9 has the kinetic energy required for cutting the waste tire during rotation.

[0038] Working principle: Place the strip of waste tire between the two cutters 25 and prepare to cut. When the strip of waste tire passes the bottom of the rotating wheel 12, due to the certain thickness and irregularity of the waste tire, it will come into contact with the pressure head 15. After the pressure head 15 comes into contact with the waste tire, it will be squeezed by the waste tire. Due to the different thicknesses of different waste tires, the pressure on the pressure head 15 will also vary. When the pressure head 15 is under pressure, it will drive the sliding plate 13 fixed to it to slide. The sliding direction of the sliding plate 13 inside the rotating wheel 12 depends on the direction of the pressure on the pressure head 15. As the sliding plate 13 slides, the spring 14 fixedly connected to its adjacent side will be compressed. The spring 14 will generate an elastic force in the opposite direction of the pressure during the compression process. This elastic force will act on the sliding plate 13. When the elastic force of the spring 14 is balanced with the pressure of the waste tire on the pressure head 15, the pressure head 15 will stably apply a fixed force to the waste tire. This is achieved through the spring 14 and the pressure head 1 The adaptive fixing method implemented by 5 can effectively fix waste tires of different thicknesses. This fixing method is crucial to the cutting process, thereby ensuring that the waste tires maintain a stable position during the cutting process of the cutting knife 9. Stable fixation helps to produce rubber blocks that meet the requirements, thereby avoiding the waste tires from being displaced or shaken during the cutting process, thereby ensuring the cutting accuracy. If the waste tires are not effectively fixed, the cutting knife 9 will cause the cutting surface to be uneven due to the movement of the waste tires during cutting, and the size and shape of the cut rubber blocks will deviate. Through this fixing method, waste generated due to size and shape not meeting the requirements is reduced. The reduction in the waste rate means that the effective utilization rate of raw materials is improved. At the same time, reducing waste also saves time and cost for reprocessing or handling the waste, which includes the resources consumed in re-cutting, sorting, transportation and other links, thereby improving the overall production efficiency and making the entire waste tire recycling process more economical and efficient.

[0039] When the tool 25 needs to be disassembled, a series of operations are required. First, the operator pulls the slide plate 23, and the slide plate 23 starts to slide inside the fixed block 16. The sliding direction of the slide plate 23 depends on the pulling force direction applied by the operator. The sliding of the slide plate 23 drives the rotating plate 22 rotatably connected thereto to rotate. The rotating plate 22 rotates around its rotation connection point with the sliding block 21 under the pulling of the slide plate 23. The rotation angle of the rotating plate 22 changes with the sliding distance of the slide plate 23. The rotation of the rotating plate 22 causes the connected sliding block 21 to slide on the support rod 19. The sliding direction of the sliding block 21 is related to the rotation direction of the rotating plate 22, and it moves along the support rod 19 away from the bolt 24. During the movement of the sliding block 21, the second spring 20 connected thereto is compressed. The second spring 20 stores elastic potential energy during the compression process to prepare for the subsequent reset action. As the sliding block 21 moves, it gradually disengages from the grooves formed on the left and right sides inside the bolt 24. When the sliding block 21 is completely disengaged from the bolt 24, the bolt 24 is no longer fixed by the sliding block 21. At this time, the bolt 24 can be disassembled from the upper and lower sides inside the fixed block 16, thereby releasing the fixation of the tool 25. Through this convenient disassembly method, the tool 25 can be easily disassembled for inspection. During the inspection process, the wear condition of the tool 25 can be clearly observed, such as the sharpness of the cutting edge, the wear marks on the tool surface, etc. If it is found that the tool 25 is worn or damaged, maintenance operations such as cleaning, grinding, and replacing worn parts can be performed on it. Through these maintenance and repair operations, the good performance of the tool 25 can be ensured, its service life can be extended, the replacement frequency of the tool 25 can be reduced, thereby reducing production costs and improving the use efficiency of the equipment.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
