Description

Technical Field

[0001] This utility model relates to the field of end-of-life vehicle tire recycling technology, and in particular to an end-of-life vehicle tire dismantling device. Background Technology

[0002] Patent application number CN202422385913.1 discloses a waste tire recycling and dismantling device. This solution solves the problem that common tire and rim dismantling machines require manual placement of the wheel on the device for separation, followed by manual collection and processing of the separated rim and tire. This method places a significant workload on recycling personnel. However, this solution still has the following problems:

[0003] In the field of end-of-life vehicle tire recycling and processing, the separation of tires from rims is a key step. Traditional disassembly methods have many drawbacks. Currently, most processing scenarios rely on manual operation or simple tools, which is not only labor-intensive but also requires operators to continuously apply force. Long-term operation can easily lead to fatigue, significantly reducing disassembly efficiency and making it difficult to meet the needs of batch processing.

[0004] Meanwhile, the force control during manual operation relies entirely on experience. If too much force is applied, it can easily cause wheel hub deformation or tire rubber tearing, damaging the integrity of recyclable parts and affecting their subsequent recycling value. If insufficient force is applied, the two cannot be effectively separated, and repeated operation will only exacerbate the wear and tear on the parts.

[0005] Traditional equipment often lacks a stable support structure, which makes it prone to shaking during operation, leading to inaccurate positioning during disassembly and increasing the difficulty of operation. In addition, existing devices mostly adopt a single power mode, either relying entirely on manual operation or only achieving simple electric drive, which is difficult to adapt to the disassembly needs of tires with different wear levels and specifications. For tires that are tightly stuck or severely rusted, manual operation is difficult to provide sufficient force, while fixed-mode electric drive may cause component damage due to uncontrollable force.

[0006] In terms of transmission and rotation mechanisms, traditional designs often suffer from low power transmission efficiency, rapid component wear, high equipment failure rate, and short service life due to insufficient lubrication or loose structure. At the same time, the disassembly process requires manual adjustment of the relative position of the tires and the disassembled parts, which cannot achieve circumferential automatic separation, further extending the operation time and increasing labor costs.

[0007] In addition, if parts accidentally slip or pop out when operators are in close contact with the disassembly parts, it can easily cause safety accidents and pose a significant safety hazard. These problems make the traditional method of disassembling scrapped car tires significantly inadequate in terms of efficiency, safety, component protection, and adaptability, which restricts the efficient development of the scrapped tire recycling and processing industry.

[0033] Please see Figure 1-4 This utility model provides a technical solution: a scrapped car tire dismantling device, including a base 1, a rotating rod 20 rotatably connected to the base 1 via a deep groove ball bearing, a hub 3 fixedly installed on the upper end of the rotating rod 20 by bolts, a tire 2 fitted on the hub 3, a worm gear 19 fixedly installed on the lower end of the rotating rod 20, a gearbox 17 and a stepper motor 16 fixedly installed at the bottom of the base 1, the output shaft of the stepper motor 16 extends into the gearbox 17 and is fixedly connected to a worm 18, the worm gear 19 and the worm 18 mesh and drive each other in the gearbox 17, and a dismantling execution component is fixedly installed on the base 1;

[0034] The base 1 provides the installation foundation and support for the entire equipment. The base 1 is rotatably connected to the rotating rod 20 through a deep groove ball bearing. The deep groove ball bearing can reduce the frictional resistance when the rotating rod 20 rotates, ensuring its stable rotation. The upper end of the rotating rod 20 is fixedly installed with a wheel hub 3 by bolts, so that the wheel hub 3 rotates synchronously with the rotating rod 20. The tire 2 fitted on the wheel hub 3 is the object to be removed and rotates together with the wheel hub 3.

[0035] The worm gear 19 fixedly installed at the lower end of the rotating rod 20 forms a meshing transmission with the worm 18 in the gearbox 17 at the bottom of the base 1. When the stepper motor 16 starts, its output shaft drives the worm 18 to rotate in the gearbox 17. The worm 18 drives the worm gear 19 to rotate through the meshing action, thereby driving the rotating rod 20, the wheel hub 3 and the tire 2 to rotate synchronously. This rotation action can make the gap between the tire 2 and the wheel hub 3 move circumferentially, and cooperate with the disassembly execution component to achieve a full circumferential separation operation.

[0036] The disassembly execution components include: pry bar 4, pressure bar 5, support column 6, lever 7, handle 8, steel cable 9, drum 10, rotating shaft 11, servo motor 12, drive pulley 13, synchronous belt 14, and driven pulley 15;

[0037] The support column 6 is vertically fixedly installed on the top of the base 1. The lever 7 is rotatably installed on the top of the support column 6 via a pin. One end of the lever 7 is fixedly installed with a handle 8, and this end is connected to one end of a steel cable 9 via a spring.

[0038] The other end of lever 7 is rigidly fixed to one end of pressure rod 5, and the other end of pressure rod 5 is connected to pry plate 4 through fine-tuning hinge. The lower end of pry plate 4 is aligned with the gap between tire 2 and wheel hub 3.

[0039] The rotating shaft 11 is rotatably connected to the base 1 via a bearing, the drum 10 is fixedly sleeved in the middle of the rotating shaft 11, the other end of the steel cable 9 is wound around the drum 10, and the driven pulley 15 is fixedly installed at the end of the rotating shaft 11.

[0040] The servo motor 12 is fixedly mounted on the base 1 and located next to the rotating shaft 11. The drive pulley 13 is fixedly mounted on the output shaft of the servo motor 12. The drive pulley 13 and the driven pulley 15 are driven by a synchronous belt 14.

[0041] The disassembly execution component is the core functional component for separating the tire 2 from the wheel hub 3. The various parts work together to achieve the disassembly action: the pry bar 4 is directly inserted into the gap between the tire 2 and the wheel hub 3 and applies a separation force; the pressure bar 5 is used to transmit the force of the lever 7 to the pry bar 4; the support column 6 provides a fulcrum for the lever 7 to rotate; the lever 7 amplifies and transmits the force by rotating around the fulcrum; the handle 8 allows the operator to manually apply the force; the steel cable 9 is used to transmit the power of the servo motor 12 to the lever 7; the drum 10 controls its length by winding and unwinding the steel cable 9; the driving pulley 13 forms a meshing transmission with the driven pulley 15 through the synchronous belt 14; the rotation of the driving pulley 13 is transmitted to the driven pulley 15 through the synchronous belt 14, which in turn drives the rotating shaft 11 and the drum 10 to rotate, realizing the winding and unwinding of the steel cable 9. This transmission process can precisely control the pulling distance and force of the steel cable 9, and together with the lever 7 and the pressure bar 5, it drives the pry bar 4 to complete the separation operation of the tire 2 from the wheel hub 3.

[0042] Working principle: When in use, after the equipment is started, the stepper motor 16 drives the worm gear 18 to rotate. The worm gear 18 meshes with the worm wheel 19, causing the rotating rod 20 to drive the hub 3 and tire 2 to rotate synchronously. At the same time, the servo motor 12 drives the driven pulley 15 through the active pulley 13 and the synchronous belt 14, driving the rotating shaft 11 and the drum 10 to rotate. The drum 10 winds up and unwinds the steel cable 9, pulling the lever 7 to rotate around the support column 6. The lever 7 pushes the pry plate 4 through the pressure rod 5 to insert into the gap between the tire 2 and the hub 3 and apply separation force. The handle 8 can assist in aligning and manually applying force. The spring buffers the force conflict between electric and manual operation. With the rotation of the tire 2 and the hub 3, full circumferential separation is achieved.

[0043] The high-strength structure of the base 1 ensures the overall stability of the equipment, provides reliable support for each component, and ensures safe operation. The deep groove ball bearing makes the rotating rod 20 rotate smoothly. In conjunction with the stepper motor 16 driving the worm gear 18 and worm wheel 19, the hub 3 and tire 2 rotate stably, realizing full-circumferential automatic separation without the need for manual adjustment, thus improving operating efficiency.

[0044] In the disassembly execution components, the wedge-shaped design of the pry bar 4, combined with the fine-tuning hinge, can be precisely inserted into the gap between the tire 2 and the wheel hub 3, avoiding excessive damage to both and facilitating subsequent recovery. The lever 7 forms a fulcrum through the support column 6 to amplify the force. In conjunction with the servo motor 12, the drum 10 driven by the active pulley 13, the synchronous belt 14, and the driven pulley 15 can wind up and unwind the steel cable 9, which can output stable pulling force electrically. At the same time, the handle 8 provides manual assistance, and the spring buffers the force conflict, adapting to different disassembly difficulty scenarios and reducing manual labor intensity.

[0045] The lubrication design of gearbox 17 reduces wear on worm gear 18 and worm wheel 19, extending equipment life; the cooperation between shaft 11 and bearing ensures stable rotation of drum 10; the high strength of steel cable 9 ensures efficient power transmission; the overall structure combines automation and flexibility, improving the convenience and reliability of tire disassembly.
