Description

Technical Field

[0001] This utility model relates to the field of tire barrel forming technology, specifically, to a tire barrel diameter measuring device. Background Technology

[0002] During the tire molding process, the diameter of the tire barrel changes due to the influence of the rubber compound, the pressure of the central drum, and the pressure of the sector blocks. However, the length of the material automatically cut by the conveyor belt can only be set to a fixed value according to the formula. The fixed length during the molding process cannot meet the joint overlap amount required by the process. Although the joint overlap qualification rate is high when the material is cut manually, it affects the molding efficiency. During the tire barrel molding process, the tire barrel diameter cannot be fed back in real time to calculate the outer circumference, so the corresponding material length cannot be fixed. Utility Model Content

[0003] This invention proposes a device for measuring the diameter of a tire barrel, which solves the problem of low efficiency in the manual cutting and forming of materials in the prior art.

[0004] The technical solution of this utility model is as follows:

[0005] A tire barrel diameter measuring device includes a frame and a tire barrel forming assembly mounted on the frame. The tire barrel forming assembly includes a forming cylinder rotatably mounted on the frame and a measuring assembly. The measuring assembly includes a measuring wheel rotatably mounted on the frame, which rotates with the forming cylinder. The measuring wheel also includes a meter counter mounted on the frame and rotating with the measuring wheel, which calculates the travel distance of the outer ring of the measuring wheel. The meter counter is electrically connected to an automatic conveyor belt cutting device.

[0006] As a further technical solution, the measuring assembly also includes a telescopic rod mounted on the frame, with a mounting bracket on the telescopic end of the telescopic rod. The measuring wheel and the meter counter are mounted on the frame via the mounting bracket. It also includes an elastic element sleeved on the telescopic rod, with one end located at the telescopic end of the telescopic rod and the other end located on the telescopic rod. The elastic element is used to provide force for the mounting bracket to approach the forming cylinder.

[0007] As a further technical solution, the measuring wheel surface is provided with several anti-slip protrusions arranged in a circular pattern.

[0008] As a further technical solution, a starting component is also included, which is used to control the start and stop rotation of the measuring wheel.

[0009] As a further technical solution, the surface of the measuring wheel has an annular groove, and a number of first teeth are arranged on the inner circumference of the annular groove. The starting component includes a first sliding rod slidably arranged on the frame. After the first sliding rod slides on the frame, it approaches or moves away from the first teeth. A second tooth is arranged at the end of the first sliding rod that approaches the first teeth. After the second tooth slides on the frame with the first sliding rod, the second tooth is used to engage or not engage the first teeth.

[0010] As a further technical solution, it also includes a rotating shaft rotatably mounted on the frame. The forming cylinder is rotatably mounted on the frame via the rotating shaft. The rotating shaft has an abutment protrusion. The starting component also includes a first hinge rod and a second hinge rod mounted on the frame. One end of the first hinge rod is hinged to the end of the first sliding rod away from the second tooth. One end of the second hinge rod is hinged to the other end of the first hinge rod. The other end of the second hinge rod is an abutment end. After the rotating shaft rotates on the frame, the abutment end is used to abut against the abutment protrusion or against the surface of the rotating shaft. The center of the first hinge rod is hinged to the frame.

[0011] As a further technical solution, both the abutting end and the abutting protrusion have guide slopes.

[0012] As a further technical solution, the frame has a mounting slot, and both the first hinge rod and the second hinge rod are located in the mounting slot.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] In this embodiment, during the tire molding process, the diameter of the tire carcass tube changes due to various factors such as the rubber compound, the pressure of the central drum, and the pressure of the sector blocks. However, traditional automatic conveyor belt cutting devices can only cut materials to a preset fixed length. This fixed cutting length cannot meet the required overlap of the joints in the process. While manual cutting has a high overlap qualification rate, it severely affects molding efficiency. Furthermore, the existing technology lacks a device that can provide real-time feedback on the tire carcass diameter and calculate the outer circumference during the tire carcass molding process, making it impossible to fix the corresponding material length based on the actual diameter of the tire carcass. This solution includes a frame, a tire carcass molding assembly, and a measuring assembly. The molding cylinder in the tire carcass molding assembly is driven by a motor to rotate on the frame, and the rubber compound is evenly spread on it to form the tire carcass tube. The measuring wheel in the measuring assembly is closely matched with the molding cylinder and rotates with the molding cylinder. The measuring wheel's outer ring movement distance is calculated in real time by a meter counter, thereby indirectly measuring the diameter of the molding cylinder and calculating its outer circumference. The meter counter is electrically connected to the automatic cutting device of the conveyor belt, which transmits the measurement data to the cutting device in real time. This allows the device to dynamically adjust the cutting length according to the actual outer circumference of the forming cylinder, ensuring that the length of the cut material meets the joint overlap requirements of the process, thereby improving forming efficiency and product quality.

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] Example

[0023] like Figures 1-4 As shown, a tire barrel diameter measuring device includes a frame 1 and a tire barrel forming assembly 2 mounted on the frame 1. The tire barrel forming assembly 2 includes a forming cylinder 3 rotatably mounted on the frame 1 and a measuring assembly 4. The measuring assembly 4 includes a measuring wheel 5 rotatably mounted on the frame 1, which rotates with the forming cylinder 3. The measuring wheel 5 also includes a meter counter 6 mounted on the frame 1 and rotating with the measuring wheel 5. The meter counter 6 is used to calculate the travel distance of the outer ring of the measuring wheel 5. The meter counter 6 is electrically connected to an automatic conveyor belt cutting device.

[0024] In this embodiment, during the tire molding process, the diameter of the tire body tube changes due to various factors such as the rubber compound, the pressure of the central drum, and the pressure of the sector blocks. However, traditional automatic conveyor belt cutting devices can only cut materials to a preset fixed length. This fixed cutting length cannot meet the required overlap of the joints in the process. While manual cutting has a high overlap qualification rate, it seriously affects molding efficiency. Furthermore, the existing technology lacks a device that can provide real-time feedback on the tire barrel diameter and calculate the outer circumference during the tire barrel molding process, making it impossible to fix the corresponding material length based on the actual diameter of the tire barrel. This solution includes a frame 1, a tire barrel molding assembly 2, and a measuring assembly 4. The molding cylinder 3 in the tire barrel molding assembly 2 is driven by a motor to rotate on the frame 1, and the rubber compound is evenly spread on it to form the tire body tube. The measuring wheel 5 in the measuring assembly 4 is closely fitted with the molding cylinder 3 and rotates with the molding cylinder 3. The distance the outer ring of the measuring wheel 5 moves is calculated in real time by a meter counter 6, thereby indirectly measuring the diameter of the molding cylinder 3 and calculating the outer circumference. The meter counter 6 is electrically connected to the automatic cutting device of the conveyor belt, which transmits the measurement data to the cutting device in real time, so that the cutting length can be dynamically adjusted according to the actual outer circumference of the forming cylinder 3, ensuring that the length of the cut material meets the joint overlap amount required by the process, thereby improving the forming efficiency and product quality.

[0025] Furthermore, the measuring assembly 4 also includes a telescopic rod 7 mounted on the frame 1, with a mounting bracket 8 mounted on the telescopic end of the telescopic rod 7. The measuring wheel 5 and the meter counter 6 are mounted on the frame 1 via the mounting bracket 8. It also includes an elastic element 9 sleeved on the telescopic rod 7, with one end located at the telescopic end of the telescopic rod 7 and the other end located on the telescopic rod 7. The elastic element 9 is used to provide force for the mounting bracket 8 to approach the forming cylinder 3.

[0026] In this embodiment, the measuring assembly 4 also includes a telescopic rod 7 mounted on the frame 1. A mounting bracket 8 for fixing the measuring wheel 5 and the meter counter 6 is installed on the telescopic end of the telescopic rod 7. Through the telescopic function of the telescopic rod 7, the mounting bracket 8 can flexibly adjust the distance between the measuring wheel 5 and the forming cylinder 3, ensuring that the measuring wheel 5 can closely contact the outer surface of the forming cylinder 3, thereby improving the accuracy and reliability of the measurement. Furthermore, an elastic element 9 is fitted onto the telescopic rod 7. One end of the elastic element 9 is connected to the telescopic end of the telescopic rod 7, and the other end is connected to the telescopic rod 7, providing a continuous elastic force so that the mounting bracket 8 always tends to approach the forming cylinder 3. This design not only effectively addresses the slight changes in the diameter of the forming cylinder 3 that may occur during the forming process, ensuring that the measuring wheel 5 and the forming cylinder 3 always maintain good contact, but also avoids poor contact between the measuring wheel 5 and the forming cylinder 3 due to mechanical vibration or external interference, thereby further improving the stability and accuracy of the measurement. Through the synergistic effect of the telescopic rod 7 and the elastic element 9, the measuring component 4 can adapt to various changes in the tire forming process more flexibly and stably, providing a strong guarantee for real-time and accurate measurement of the tire barrel diameter and calculation of the outer circumference, thereby providing a more accurate basis for the cutting length control of the automatic conveyor belt cutting device, and further improving the process level and product quality of tire forming.

[0027] Furthermore, the surface of the measuring wheel 5 is provided with several anti-slip protrusions 10 arranged in a circular pattern.

[0028] In this embodiment, a plurality of anti-slip protrusions 10 are evenly arranged on the circumferential direction of the surface of the measuring wheel 5. These anti-slip protrusions 10 can effectively increase the friction between the measuring wheel 5 and the outer surface of the forming cylinder 3, prevent the measuring wheel 5 from slipping during rotation, and thus further improve the measurement accuracy and reliability.

[0029] Furthermore, it also includes a starting component 11 disposed on the frame 1, which is used to control the measuring wheel 5 to start and stop rotating.

[0030] In this embodiment, the tire barrel diameter measuring device also includes a starting component 11 mounted on the frame 1. The starting component 11 can precisely control the start and stop rotation of the measuring wheel 5 to ensure the accuracy and synchronization of the measurement process, thereby providing a reliable guarantee for the accurate measurement of the tire barrel diameter.

[0031] Furthermore, the surface of the measuring wheel 5 has an annular groove 12, and a plurality of first teeth 13 are arranged on the inner circumference of the annular groove 12. The starting component 11 includes a first sliding rod 14 slidably arranged on the frame 1. After the first sliding rod 14 slides on the frame 1, it approaches or moves away from the first teeth 13. A second tooth 15 is arranged at the end of the first sliding rod 14 that approaches the first teeth 13. After the second tooth 15 slides on the frame 1 with the first sliding rod 14, the second tooth 15 is used to engage or not engage the first teeth 13.

[0032] In this embodiment, the surface of the measuring wheel 5 is provided with an annular groove 12, and a plurality of first teeth 13 are provided on the inner circumference of the annular groove 12; the starting component 11 includes a first sliding rod 14 slidably disposed on the frame 1, and a second tooth 15 is provided at one end of the first sliding rod 14 near the measuring wheel 5. By pushing the first sliding rod 14 to slide along the frame 1, the second tooth 15 can be engaged or disengaged from the first tooth 13, thereby achieving precise control of the rotation of the measuring wheel 5 and ensuring the synchronization and reliability of the measurement process.

[0033] Furthermore, it also includes a rotating shaft 16 rotatably mounted on the frame 1. The forming cylinder 3 is rotatably mounted on the frame 1 via the rotating shaft 16. The rotating shaft 16 has an abutment protrusion 17. The starting component 11 also includes a first hinge rod 18 and a second hinge rod 19 mounted on the frame 1. One end of the first hinge rod 18 is hinged to the end of the first sliding rod 14 away from the second tooth 15. One end of the second hinge rod 19 is hinged to the other end of the first hinge rod 18. The other end of the second hinge rod 19 is an abutment end 20. After the rotating shaft 16 rotates on the frame 1, the abutment end 20 is used to abut against the abutment protrusion 17 or abut against the surface of the rotating shaft 16. The center of the first hinge rod 18 is hinged to the frame 1.

[0034] In this embodiment, a rotating shaft 16 is rotatably mounted on the frame 1. The forming cylinder 3 is mounted on the frame 1 via the rotating shaft 16 and can rotate with the rotation of the rotating shaft 16. The rotating shaft 16 is provided with an abutment protrusion 17 to provide a contact point. The starting assembly 11 also includes a first hinge rod 18 and a second hinge rod 19 mounted on the frame 1. One end of the first hinge rod 18 is hinged to the end of the first sliding rod 14 away from the second tooth 15, and one end of the second hinge rod 19 is hinged to the other end of the first hinge rod 18. The other end of the second hinge rod 19 is an abutment end 20. When the rotating shaft 16 rotates on the frame 1, the abutment end 20 can abut against the abutment protrusion 17 on the rotating shaft 16 or directly abut against the surface of the rotating shaft 16 as the rotating shaft 16 rotates. At the same time, the center of the first hinge rod 18 is hinged to the frame 1, forming a lever structure. With this design, when the rotating shaft 16 rotates, the contact between the abutting end 20 of the second hinge rod 19 and the abutting protrusion 17 or the surface of the rotating shaft 16 drives the first hinge rod 18 to swing, thereby causing the first sliding rod 14 to slide along the frame 1. This sliding allows the second tooth 15 on the first sliding rod 14 to engage or disengage with the first tooth 13 on the measuring wheel 5, thus achieving precise control over the rotation of the measuring wheel 5. When the abutting end 20 abuts against the abutting protrusion 17, the first sliding rod 14 is pulled, causing the second tooth 15 to engage with the first tooth 13, and the measuring wheel 5 stops rotating; while when the abutting end 20 abuts against the surface of the rotating shaft 16, the first sliding rod 14 is released, the second tooth 15 disengages from the first tooth 13, and the measuring wheel 5 begins to rotate. This structure not only achieves precise starting and stopping of the measuring wheel 5, but also improves the reliability and stability of the system through mechanical linkage, ensuring that the measurement process is synchronized with the movement of the forming cylinder 3, further improving the accuracy and efficiency of the tire diameter measurement.

[0035] Furthermore, both the abutting end 20 and the abutting protrusion 17 have guide slopes 21.

[0036] In this embodiment, both the abutment end 20 and the abutment protrusion 17 are designed with guide slopes 21. Specifically, when the rotating shaft 16 rotates on the frame 1, the abutment end 20 of the second hinge rod 19 will contact the abutment protrusion 17 on the rotating shaft 16. Since both the abutment end 20 and the abutment protrusion 17 have guide slopes 21, this design allows for a smoother transition from the abutment protrusion 17 to the surface of the rotating shaft 16, or from the surface of the rotating shaft 16 to the abutment protrusion 17, through the guiding effect of the slopes when they come into contact.

[0037] Furthermore, the frame 1 has a mounting groove 22, and the first hinge rod 18 and the second hinge rod 19 are both located in the mounting groove 22.

[0038] In this embodiment, the frame 1 is provided with a mounting groove 22, and the first hinge rod 18 and the second hinge rod 19 are both installed in the mounting groove 22. This layout achieves a compact structure.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
