Description

Technical Field

[0001] This utility model relates to the field of tire testing technology, specifically to a tire manufacturing cord uniformity testing device. Background Technology

[0002] Tire uniformity testing equipment, also known as a tire uniformity tester, is a specialized measuring device primarily used to measure the non-uniformity of a tire during rotation, including the uniformity of the cord distribution. It uses high-precision sensors to detect and record the forces and vibrations generated during tire rotation, thereby evaluating tire uniformity, including parameters such as side-by-side alignment, radial accuracy, and roundness, as well as the uniformity of cord tension.

[0003] Existing tire manufacturing cord uniformity testing equipment typically includes a transmission body, a support frame, a cylinder, a fixing column, and a testing body. The cylinder is mounted on the support frame and controls the position and movement of the fixing column, which is used to fix the tire. Multiple testing bodies are also mounted on the support frame. Each testing body typically includes a testing roller, a motor, a belt, and a rotating rod. The motor and the rotating rod are connected by a belt. The motor drives the rotating rod to rotate, which in turn drives the testing roller to rotate. The testing roller is used to detect the uniformity of the tire while it is rotating. However, in the use of existing equipment, because the size of the fixing column is fixed, it cannot fix smaller tires. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tire cord uniformity testing device, which solves the problem that in the use of existing equipment, the fixed size of the fixing post makes it impossible to fix smaller tires.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tire production cord uniformity testing device, which is mounted on a transmission body and includes a support frame and multiple testing bodies mounted on the support frame. The support frame is also provided with an adjustment device and a limiting device at the bottom of the adjustment device. The adjustment device is used to control the vertical position of the limiting device, and the limiting device can rotate around the center position of the adjustment device.

[0006] The limiting device includes a driving component, a fixed disk, a rotating disk, and multiple extrusion groups. The driving component is disposed inside the adjusting device. The output end of the driving component passes through the fixed disk. The outer side wall of the fixed disk is fixedly connected to the inner side wall of the adjusting device. The output end of the driving component is fixedly connected to the upper end of the rotating disk. All of the multiple extrusion groups extend into the interior of the fixed disk.

[0007] The extrusion assembly includes an extrusion plate, a connecting plate, and a guide rod. One end of the connecting plate extends into a movable groove on the fixed disk. The end of the connecting plate near the movable groove is fixedly connected to one end of the guide rod. The bottom of the guide rod is movably disposed in an arc-shaped guide groove on the rotating disk. The end of the connecting plate away from the guide rod is fixedly connected to one side of the extrusion plate. The cross-section of the extrusion plate is arc-shaped.

[0008] Preferably, the adjusting device includes a cylinder, a connecting column, and a fixing column. The cylinder is mounted on the support frame, and the output end of the cylinder is fixedly connected to the upper end of the connecting column. The upper end of the fixing column is movably connected to the bottom end of the connecting column. The driving component is installed inside the fixing column, and the outer wall of the fixing plate is fixedly connected to the inner wall of the fixing column.

[0009] Preferably, the outer wall of the fixing column is provided with multiple heat dissipation holes.

[0010] Preferably, multiple mounting plates are fixedly connected to the support frame, and the multiple detection subjects are respectively mounted on the multiple mounting plates.

[0011] Preferably, the detection body includes a detection roller, a support plate, a motor, a rotating rod, and a belt. The motor is mounted on the support plate, and the output end of the motor is connected to the rotating rod via the belt. The bottom end of the rotating rod is fixedly connected to the upper end of the detection roller.

[0012] Preferably, the driving component is a second motor, and the output end of the second motor is fixedly connected to the upper end of the rotating disk.

[0013] Compared with the prior art, this utility model provides a tire manufacturing cord uniformity testing device, which has the following advantages:

[0014] The device drives a rotating disk to rotate via a drive component. During the rotation of the disk, the guide rod is squeezed and moves inside the guide groove. Since the guide groove is arc-shaped, the movement of the guide rod causes the connecting plate to move away from the fixed disk. The movement of the connecting plate then drives the squeezing plate to move. During this movement, the squeezing plate comes into contact with the inner wall of the tire. The squeezing plate continuously applies a pushing force to the inner wall of the tire, thus fixing the tire in place. The different rotation amplitudes of the rotating disk result in different extension lengths of the connecting plate, allowing it to accommodate both small and large tires, thus increasing the versatility of the overall equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figure 1-6 In this embodiment: a tire production cord uniformity testing device, the device is set on a transmission body 1, including a support frame 2 and multiple testing bodies set on the support frame 2, the support frame 2 is also provided with an adjustment device and a limiting device set at the bottom of the adjustment device, the adjustment device is used to control the vertical position of the limiting device, and the limiting device can rotate around the center position of the adjustment device.

[0024] The limiting device includes a driving component, a fixed disk 14, a rotating disk 15, and multiple extrusion groups. The driving component is located inside the adjusting device. The output end of the driving component passes through the fixed disk 14. The outer side wall of the fixed disk 14 is fixedly connected to the inner side wall of the adjusting device. The output end of the driving component is fixedly connected to the upper end of the rotating disk 15. The multiple extrusion groups extend into the interior of the fixed disk 14.

[0025] The extrusion assembly includes an extrusion plate 13, a connecting plate 17, and a guide rod 19. One end of the connecting plate 17 extends into a movable groove provided on the fixed disk 14. The end of the connecting plate 17 near the movable groove is fixedly connected to one end of the guide rod 19. The bottom of the guide rod 19 is movably disposed in an arc-shaped guide groove 18 provided on the rotating disk 15. The end of the connecting plate 17 away from the guide rod 19 is fixedly connected to one side of the extrusion plate 13. The cross-section of the extrusion plate 13 is arc-shaped. The driving component is a second motor 16. The output end of the second motor 16 is fixedly connected to the upper end of the rotating disk 15.

[0026] Specifically, the device drives the rotating disk 15 to rotate via motor 16. During the rotation of the rotating disk 15, the guide rod 19 is squeezed and moves inside the guide groove 18. Since the guide groove 18 is arc-shaped, the movement of the guide rod 19 will drive the connecting plate to move away from the fixed disk 14. The movement of the connecting plate will drive the squeezing plate 13 to move. During this movement, the squeezing plate 13 will contact the inner wall of the tire. The squeezing plate 13 continuously applies a pushing force to the inner wall of the tire, thereby fixing the tire. The different rotation amplitudes of the rotating disk 15 result in different extension lengths of the connecting plate, which can accommodate small or large tires, making the overall equipment more versatile.

[0027] The adjustment device includes a cylinder 3, a connecting column 10, and a fixed column 11. The cylinder 3 is mounted on the support frame 2. The output end of the cylinder 3 is fixedly connected to the upper end of the connecting column 10. The upper end of the fixed column 11 is movably connected to the bottom end of the connecting column 10. The driving component is installed inside the fixed column 11. The outer side wall of the fixed plate 14 is fixedly connected to the inner side wall of the fixed column 11.

[0028] Specifically, during use, the vertical position of the fixed column 11 can be adjusted by starting the cylinder 3, so that the fixed column 11 can enter the interior of the tire. Since the fixed column 11 and the connecting column 10 are movably connected, the fixed column 11 can rotate after fixing the tire, so that the overall equipment runs smoothly.

[0029] The outer wall of the fixed column 11 is provided with multiple heat dissipation holes 12. The multiple heat dissipation holes 12 are provided to ensure the stability of the motor 16 during use.

[0030] Multiple mounting plates 4 are fixedly connected to the support frame 2. Multiple detection bodies are respectively installed on the multiple mounting plates 4. The detection body includes a detection roller 5, a support plate 6, a motor 9, a rotating rod 7, and a belt 8. The motor 9 is installed on the support plate 6. The output end of the motor is connected to the rotating rod 7 through the belt 8. The bottom end of the rotating rod 7 is fixedly connected to the upper end of the detection roller 5. The rotating rod 7 is driven to rotate by the motor 9. The rotation of the rotating rod 7 drives the detection roller 5 to rotate. The detection roller 5 is used to detect the uniformity of the tire in the rotating state.

[0031] The working principle and usage process of this utility model: When the device is in use, the rotating rod 7 is driven to rotate by the motor 9, and the rotation of the rotating rod 7 drives the detection roller 5 to rotate. The detection roller 5 detects the uniformity of the tire in the rotating state.

[0032] For tire fixing, the rotating disk 15 is driven by the motor 16. During the rotation of the rotating disk 15, the guide rod 19 is squeezed and moves inside the guide groove 18. Since the guide groove 18 is set in an arc shape, the movement of the guide rod 19 will drive the connecting plate to move away from the fixing disk 14. The movement of the connecting plate will drive the squeezing plate 13 to move. During this movement, the squeezing plate 13 will contact the inner wall of the tire. The squeezing plate 13 continuously applies a pushing force to the inner wall of the tire, thereby fixing the tire. The different rotation amplitudes of the rotating disk 15 result in different extension lengths of the connecting plate, which can accommodate small or large tires, making the overall equipment more versatile.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
