Description

Technical Field

[0001] This utility model relates to the technical field of waste vehicle processing equipment, and in particular to a tensioning and bearing device for a tire rolling machine. Background Technology

[0002] The tire thread rolling machine is a cold forming device specifically designed for the efficient processing of tire bolt threads. Its core function is to roll high-precision threads (accuracy up to ±0.01mm) from tire bolt blanks in a single pass at room temperature using synchronous extrusion from high-strength rolling plates (stationary and moving plates). The machine employs a hydraulic closed-loop system to provide a constant pressure of 200-500kN, combined with an adaptive centering fixture to ensure zero-deflection feed of the bolt blank. This results in a 30% increase in the shear strength of the thread profile (reaching HV350 or higher), while simultaneously avoiding material waste during turning processes. It is widely used in the mass production of high-strength bolts in automobile factories, tire manufacturing, and repair centers.

[0003] However, existing equipment often encounters the following problems during use:

[0004] Existing tire shredding machines typically involve attaching the tire to the shredding rollers during the shredding process. However, once the rollers rotate, centrifugal force can cause the tire to detach from the rollers, requiring manual intervention to continuously straighten the tire and ensure normal operation, which is extremely inconvenient. Utility Model Content

[0005] The main purpose of this utility model is to provide a tensioning and bearing device for a tire shredding machine, so as to effectively solve the problem mentioned in the background art that when existing tire shredding machines shred tires into filaments, the tire is usually fitted between the shredding rollers for operation. However, once the rollers rotate, centrifugal force will be generated, causing the tire to detach from the rollers. At this time, it is necessary to manually straighten the tires continuously to ensure normal operation, which is very inconvenient.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A tensioning and bearing device for a tire rolling mill includes:

[0008] Thread rolling machine body;

[0009] A fixed housing plate is horizontally fixedly installed on the front side of the wire rolling machine body;

[0010] The first drive wheel, the central shaft of the first drive wheel is movably mounted on the fixed housing plate;

[0011] The second drive wheel is located in the extension direction of the side wheel surface of the first drive wheel;

[0012] A tension belt, one end of which is fitted onto the first drive wheel, and the other end of which is fitted onto the second drive wheel;

[0013] A sliding element, which is sleeved on a portion of the transverse belt of the tensioning belt;

[0014] A transverse tensioning plate, which is parallel to the fixed housing plate, and one end of the transverse tensioning plate is fixedly connected to the sliding member;

[0015] The other end of the transverse tensioning plate is movably mounted on a tensioning wheel.

[0016] Also includes:

[0017] A vertical transition assembly is provided, in which the transmission belt is supported. The vertical transition assembly includes a vertical support frame, a horizontal support frame, a transition pressing frame, a transition roller, a rotating shaft wheel, and a transmission roller. The vertical support frame is L-shaped and extends along the front of the fixed housing plate. The horizontal support frame is fixed to the frame of the vertical support frame and is located below the rotating shaft wheel. The pressing rollers are distributed at both ends of the horizontal support frame and press against the body of the transmission belt. The transition pressing frame is installed at the transition end of the vertical transition assembly. The transition rollers are located at both ends of the vertical transition assembly and are used to press the transmission belt to achieve a vertical transition. The rotating shaft wheel is longitudinally located at the top of the vertical support frame, and the transmission roller is transversely located at the bottom of the vertical support frame.

[0018] The transmission belt has an "L" shape on its side, with the top end of the transmission belt sleeved on the rotating shaft pulley and the bottom end of the transmission belt sleeved on the transmission roller.

[0019] Also includes:

[0020] The tensioning motor is longitudinally fixedly installed on the base of the thread rolling machine body, and the output end of the tensioning motor is connected to the transmission roller.

[0021] The thread rolling machine body also includes:

[0022] A shrink motor is horizontally mounted on the top of the housing of the yarn rolling machine body;

[0023] A reset gear is mounted on the output end of the retraction motor;

[0024] A displacement rack, which meshes with the reset gear;

[0025] An arc-shaped bearing shell is fixedly installed at the free end of the displacement rack.

[0026] The extrusion rollers are symmetrically arranged at both ends of the transverse support frame, and the axis of the extrusion rollers is parallel to the transmission roller.

[0027] The first drive wheel is coaxially connected to the rotating shaft wheel.

[0028] The transmission belt has a closed-loop structure and is wound sequentially around the transmission roller, the turning roller and the rotating shaft wheel.

[0029] Compared with existing technologies, the advantages of this invention are as follows: Driven by a tensioning motor, the tensioning belt maintains appropriate tension, ensuring the tire remains in a fixed position during the shredding process and preventing derailment due to centrifugal force. The retraction motor precisely engages the tire by controlling the position of the arc-shaped bearing shell, ensuring its stability and preventing loosening, allowing the tire to be stably shredded between the mixing rollers. The tensioning wheel and transverse tensioning plate precisely adjust the belt tension, maintaining a relatively constant tension on the tire during processing, thus reducing tire deviation caused by external forces (such as centrifugal force). The flexible adjustability of the tensioning system enhances the adaptability of the equipment, ensuring stable operation for different tire specifications. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] like Figure 1-4 As shown, this utility model provides a tensioning bearing device for a tire rolling mill. The tensioning bearing device for the tire rolling mill includes a rolling mill body 1, a fixed housing plate 2, a first drive wheel 3, a second drive wheel 4, a tension belt 5, a sliding member 6, a transverse tensioning plate 7, a tensioning wheel 8, and a turning vertical assembly 9.

[0039] The fixed housing plate 2 is horizontally fixedly installed on the front of the thread rolling machine body 1. The installation of the fixed housing plate 2 makes the front of the thread rolling machine body 1 more stable, providing a solid foundation support for other components. This ensures that the operation of subsequent components is not affected by external vibrations. The central shaft of the first drive wheel 3 is movably mounted on the fixed housing plate 2. The first drive wheel 3 is coaxially connected to the rotating shaft wheel 96. The second drive wheel 4 is located on the side of the first drive wheel 3, extending in the direction of its extension. These two drive wheels work together to transmit the power of the tension belt 5. The coaxial connection between the first drive wheel 3 and the rotating shaft wheel 96 ensures smooth power transmission; the second drive wheel 4 is located on the side of the first drive wheel 3 and transmits rotational force through the tension belt 5, ensuring the precise coordination of the entire tensioning system.

[0040] In this invention, one end of the tension belt 5 is sleeved on the first drive wheel 3, and the other end is sleeved on the second drive wheel 4. The design of the tension belt 5 effectively transmits power and adjusts the tension, maintaining stable operation of the system. Its two ends are connected to the drive wheels, enabling the system to achieve the predetermined tension requirements and avoiding belt slack or excessive tightness during transmission. The sliding member 6 is sleeved on a portion of the transverse belt of the tension belt 5, and its displacement is adjusted with the belt's movement. The transverse tension plate 7 connected to it supports and adjusts the position of the tension wheel 8, ensuring the system can be adjusted according to actual needs, thus achieving precise tension. The transverse tension plate 7 is parallel to the fixed housing plate 2, with one end fixedly connected to the sliding member 6; the other end of the transverse tension plate 7 is movably mounted on the tension wheel 8.

[0041] In this invention, the transmission belt 10 is supported by a vertical turning assembly 9. The vertical turning assembly 9 includes a vertical support frame 91, a horizontal support frame 92, a turning extrusion frame 94, a turning roller 95, a rotating shaft wheel 96, and a transmission roller 97. The vertical support frame 91 is L-shaped and located in the extending direction of the front of the fixed housing plate 2. The horizontal support frame 92 is fixed to the frame of the vertical support frame 91 and is located below the rotating shaft wheel 96. Extrusion rollers are distributed at both ends of the horizontal support frame 92. The pressure roller 93 presses against the belt body of the transmission belt 10. The turning and pressing frame 94 is installed at the turning end of the turning vertical component 9. The turning roller 95 is located at both ends of the turning vertical component 9. The turning roller 95 is used to press the transmission belt 10 to achieve a vertical transition. The rotating shaft wheel 96 is longitudinally located at the top of the vertical support frame 91. The transmission roller 97 is transversely located at the bottom of the vertical support frame 91. The pressure roller 93 is symmetrically located at both ends of the transverse support frame 92, and the axis of the pressure roller 93 is parallel to the transmission roller 97.

[0042] In this invention, the vertical transition component 9, through the design of the vertical support frame 91, the horizontal support frame 92, and the transition compression frame 94, helps the transmission belt 10 achieve a vertical transition. This design ensures that the transmission belt 10 maintains sufficient toughness and flexibility during operation, preventing the belt from becoming loose or breaking during bending. The transmission belt 10 has an "L" shape on its side, with its top end sleeved on the rotating shaft pulley 96 and its bottom end sleeved on the transmission roller 97. The transmission belt 10 has a closed-loop structure and is sequentially wound around the transmission roller 97, the transition roller 95, and the rotating shaft pulley 96.

[0043] In this invention, the tensioning motor 11 is longitudinally fixedly mounted on the base of the thread rolling machine body 1, and the output end of the tensioning motor 11 is connected to the transmission roller 97. The tensioning motor 11 drives the transmission roller 97 to rotate, thereby adjusting the tension of the tension belt 5. This ensures the stability and accuracy of the belt transmission process. The retraction motor 12 is responsible for controlling the position of the arc-shaped bearing shell 15, helping the tire to accurately align with the shredding roller of the thread rolling machine.

[0044] In this invention, the yarn rolling machine body 1 further includes: a shrinking motor 12 horizontally mounted on the top of the housing of the yarn rolling machine body 1; a reset gear 13 mounted on the output end of the shrinking motor 12; the reset gear 13 and the displacement rack 14 work together to adjust the position of the arc-shaped support shell 15. Through the sliding of the rack, the displacement direction and speed of the support shell can be precisely controlled, ensuring the stability of the tire within the yarn rolling machine and preventing displacement or detachment during the yarn rolling process. The displacement rack 14 meshes with the reset gear 13.

[0045] In this invention, the arc-shaped bearing shell 15 is fixedly installed on the free end of the displacement rack 14. The design of the arc-shaped bearing shell 15 enables the tire to be accurately positioned and kept stable, preventing the tire from loosening or detaching from the axle during the tire rolling process. Through its cooperation with the displacement rack 14, the position of the bearing shell can be adjusted as needed to accommodate tires of different inner diameters. The tensioning wheel 8 is designed to adjust the belt tension through its cooperation with the transverse tensioning plate 7, ensuring the stability of the tensioning belt 5 during transmission. It can effectively support the tire when the inner diameter is large, preventing problems during the tire rolling process.

[0046] It should be noted that, in the use of the tensioning and bearing device for the tire rolling machine designed in this utility model, the tire is fitted onto the arc-shaped bearing shell 15, and the retraction motor 12 is started. The output end of the motor rotates, driving the reset gear 13. The rotation of the gear drives the displacement rack 14 meshing with it. The direction of the sliding displacement of the displacement rack 14 is determined by the rotation direction of the gear. Taking the rack driving the arc-shaped bearing shell 15 to gradually approach the rolling machine body 1 as an example, when the tire enters between the two shredding rollers of the rolling machine and the inner diameter of the tire is large, in order to ensure that it will not detach from the rollers, the tensioning motor 11 is started. The output end of the motor rotates, driving the transmission roller 9. 7. The transmission roller 97 drives the transmission belt 10 of the wheel body. The rotation of the transmission belt 10 is ensured by the vertical bending component 9, until it drives the rotating shaft wheel 96 at the other end of the transmission belt 10. The rotation of the rotating shaft wheel 96 drives the first drive wheel 3 coaxially connected to it. The rotation of the first drive wheel 3 drives the second drive wheel 4 at the other end through the tension belt 5. During the transmission of the tension belt 5, the sliding member 6 sleeved on the belt will slide and move with the belt. The transverse tension plate 7 connected to the sliding member 6 will drive the tension wheel 8 at the end to gradually approach the inner diameter of the tire, supporting the tire. After the tire is supported, the tension motor 11 can be turned off. After that, the yarn rolling machine body 1 can be started normally to make the shredding roller rotate to roll the tire into yarn.
