Description

Technical Field

[0001] This utility model relates to the technical field of tire forming machine equipment, specifically a device for measuring tension by zero-degree winding of all-steel. Background Technology

[0002] Zero-degree winding on an all-steel radial tire forming machine is a key process in tire manufacturing. It specifically refers to the technology of precisely winding steel wire bundles onto the belt layer drum at a 0° angle during the forming process of all-steel radial tires. The zero-degree winding process has achieved high precision and high stability in the manufacturing of all-steel radial tires, becoming a key link in improving the overall performance of tires. During the winding process, the floating roller dynamically adjusts the tension and position of the steel wire bundle to ensure the stability of the winding process and the bonding accuracy of the belt layer. However, in the existing technology, the oscillation amplitude of the floating roller is balanced by adjusting the feeding speed and the conveyor belt feeding speed. However, since different models require different feeding speeds, the steel wire bundles may be too tight or too loose, which will affect the tire's binding force and thus the radial force of the tire.

[0003] Based on this, a device for measuring tension by zero-degree winding of all-steel is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4 As shown, a device for measuring tension of all-steel zero-degree winding includes a fixed frame 1. An I-beam 11 is provided in the inner cavity of the fixed frame 1. A guide roller 12 is rotatably connected to the inner cavity of the fixed frame 1 near the I-beam 11. A guide roller 13 is rotatably connected to the inner cavity of the fixed frame 1 near the guide roller 12. A transfer belt 14 is provided in the inner cavity of the fixed frame 1 away from the guide roller 13. An auxiliary roller 15 is rotatably connected to the inner cavity of the fixed frame 1 near the transfer belt 14. A fitting drum 16 is provided in the inner cavity of the fixed frame 1 near the auxiliary roller 15. A tension adjusting mechanism 2 is provided on the upper surface of the fixed frame 1 near the transfer belt 14. The tension adjusting mechanism 2 includes a telescopic cylinder 21 and a connecting frame 25. The outer wall of the telescopic cylinder 21 is fixedly connected to the upper surface of the fixed frame 1. A limit mechanism 3 is provided on the inner wall of the connecting frame 25.

[0025] In this embodiment, the steel wire bundle is moved by the cooperation of the I-beam frame 11, guide roller 12, guide roller 13, transfer belt 14, auxiliary roller 15, bonding drum 16 and tension adjustment mechanism 2. During the movement, the tension adjustment mechanism 2 adjusts the tension of the steel wire bundle to maintain a suitable tension range, so as to avoid the tension of the steel wire bundle being too tight or too loose, which would affect the radial force of the tire. During the adjustment of the tension of the steel wire bundle, the limiting mechanism 3 ensures that the steel wire bundle will not be displaced.

[0026] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the output end of the telescopic cylinder 21 is fixedly connected to a connecting plate 22 through the outer wall of the fixed frame 1. A slide rod 23 is fixedly connected to the upper surface of the connecting plate 22. The outer wall of the slide rod 23 is slidably connected to the inner wall of the fixed frame 1. Shock absorbers 24 are evenly distributed on the upper surface of the connecting plate 22. The bottom end of the shock absorber 24 is fixedly connected to the upper surface of the connecting frame 25. A motor 27 is fixedly connected to the inner wall of the connecting frame 25. A bidirectional threaded rod 28 is fixedly connected to the output end of the motor 27. The threads at both ends of the bidirectional threaded rod 28 have opposite directions. The motor 27 drives the two sliders 31 to move closer or further away synchronously in both forward and reverse directions. The ends of the bidirectional threaded rod 28... The zero-degree sensing roller 29 is rotatably connected to the inner wall of the connecting frame 25 and rotatably connected to the outer wall of the connecting frame 25 away from the bidirectional threaded rod 28. The tension of the steel wire bundle is detected by the zero-degree sensing roller 29. When the tension is too high or too low, the telescopic cylinder 21 is activated, which drives the connecting plate 22 to move. The connecting plate 22 drives the slide rod 23 to move synchronously. At the same time, the connecting plate 22 drives the shock absorber 24 and the connecting frame 25 to move, thereby changing the position of the zero-degree sensing roller 29 and changing the tightness between the zero-degree sensing roller 29 and the steel wire bundle. This adjusts the tension of the steel wire bundle to a suitable tension range.

[0027] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the shock absorber 24 consists of a damper and a shock-absorbing spring. When the zero-degree sensing roller 29 controls the tension of the steel wire bundle, the vibration generated when the steel wire bundle moves is absorbed by the shock absorber 24, so as to prevent the zero-degree sensing roller 29 from vibrating and affecting the tension of the steel wire bundle.

[0028] In an optional embodiment, such as Figure 2 and Figure 3 As shown, a guide block 26 is fixedly connected to the outer wall of the connecting frame 25. The outer wall of the guide block 26 is slidably connected to the inner wall of the fixing frame 1. The fixing frame 1 has a scale corresponding to the outer wall of the guide block 26. The guide block 26 limits and guides the connecting frame 25 to prevent the connecting frame 25 from moving too far or deviating during the movement.

[0029] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the limiting mechanism 3 includes a slider 31, the inner wall of which is threadedly connected to the outer wall of the bidirectional threaded rod 28. A limiting block 32 is fixedly connected to the upper surface of the slider 31, and the outer wall of the limiting block 32 is slidably connected to the inner wall of the connecting frame 25. A limiting frame 33 is attached to the upper surface of the slider 31, and a guide roller 34 is rotatably connected to the inner cavity of the limiting frame 33. An insert block 35 is fixedly connected to the upper surface of the limiting frame 33, and the outer wall of the insert block 35 is inserted into the inner wall of the slider 31. An insert rod 36 is inserted into the inner wall of the insert block 35, and the outer wall of the insert rod 36 is slidably connected to the inner wall of the slider 31. A spring 37 is sleeved on the outer wall of the insert rod 36, one end of which is fixedly connected to the outer wall of the slider 31, and the other end is connected to the insert rod. The outer wall of 36 is fixedly connected. When the motor 27 is started, it drives the bidirectional threaded rod 28 to rotate, causing the slider 31 to slide on the outer wall of the bidirectional threaded rod 28. The slider 31 drives the limit frame 33 and the guide roller 34 to move synchronously, so that the outer wall of the guide roller 34 keeps in contact with the outer wall of the steel wire bundle but not tightly. This ensures that the steel wire bundle will not deviate during the tension adjustment process. Subsequently, when the limit frame 33 needs to be replaced, the insertion rod 36 is pulled, which causes the spring 37 to extend, so that the outer wall of the insertion rod 36 is no longer inserted into the inner wall of the insertion block 35. Then the limit frame 33 can be removed and replaced, thus avoiding the problem that the entire mechanism will be unusable if a single limit frame 33 is damaged.

[0030] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the limiting block 32 is T-shaped, and the outer wall of the connecting frame 25 is provided with a matching groove. The limiting block 32 guides the slider 31 so that the slider 31 can only move horizontally and cannot rotate.

[0031] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the gap between the two limit frames 33 is 20-30mm larger than the maximum diameter of the zero-degree sensing roller 29, so that the limit frame 33 will not contact the outer wall of the zero-degree sensing roller 29 when it moves, thereby avoiding motion interference and wear.

[0032] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the insertion part of the plug rod 36 and the plug block 35 is trapezoidal. Therefore, when installing the limit frame 33, it is only necessary to push the plug block 35 towards the inner wall of the slider 31, which makes it easy to install.

[0033] The above embodiment discloses a device for measuring the tension of all-steel zero-degree winding. During operation, the tension of the steel wire bundle is detected by the zero-degree sensing roller 29. When the tension is too high or too low, the telescopic cylinder 21 is activated, moving the connecting plate 22. This causes the connecting plate 22 to move the sliding rod 23 synchronously. Simultaneously, the connecting plate 22 moves the shock absorber 24 and the connecting frame 25, thereby changing the position of the zero-degree sensing roller 29 and altering the tightness between it and the steel wire bundle. This adjusts the tension of the steel wire bundle to a suitable range. During tension adjustment, the motor 27 is activated, rotating the bidirectional threaded rod 28. This causes the slider 31 to slide on the outer wall of the bidirectional threaded rod 28. The slider 31 moves the limiting frame 33 and the guide roller 34 synchronously, ensuring that the outer wall of the guide roller 34 remains in contact with, but not tightly against, the outer wall of the steel wire bundle. The tightness of the tension adjustment mechanism ensures that the steel wire bundle will not shift during tension adjustment. Later, when the limit frame 33 needs to be replaced, pulling the insertion rod 36 extends the spring 37, causing the outer wall of the insertion rod 36 to no longer engage with the inner wall of the insertion block 35. The limit frame 33 can then be removed and replaced, thus avoiding the problem of the entire mechanism becoming unusable due to damage to a single limit frame 33. In summary, the steel wire bundle is moved by the cooperation of the I-beam frame 11, guide roller 12, guide roller 13, transfer belt 14, auxiliary roller 15, bonding drum 16, and tension adjustment mechanism 2. During the movement, the tension adjustment mechanism 2 adjusts the tension of the steel wire bundle to maintain a suitable tension range, preventing the tension from being too tight or too loose, which would affect the radial force of the tire. During the tension adjustment of the steel wire bundle, the limit mechanism 3 ensures that the steel wire bundle will not shift.

[0034] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
