Abstract
Description
Technical Field
[0001] This utility model relates to the field of nylon crown belt winding technology, and in particular to a crown belt tension protection structure and crown belt winding equipment. Background Technology
[0002] The nylon crown strip winding equipment on radial tire forming machines is used to precisely wind nylon crown strips onto the tire carcass during tire manufacturing to enhance the tire's strength and durability. The tension control system in the winding equipment maintains appropriate tension on the nylon crown strip during the winding process, preventing it from being too loose or too tight. However, abnormal tension can easily occur during the winding and conveying of the crown strip material, leading to overstretching or loosening of the nylon crown strip, resulting in winding abnormalities and, in severe cases, equipment damage.
[0003] In view of this, the present invention proposes a tension protection structure for crown belt equipment and a crown belt winding device. Utility Model Content
[0004] This utility model aims to address the shortcomings of the above-mentioned technical solutions by providing a tension protection structure for crown belt equipment. By using a magnet with a magnetic base to attract the floating wheel bracket and the floating wheel, when there is an abnormal tension in the crown belt strip wound through the floating wheel, the excessive force will pull the floating wheel and the floating wheel bracket away from the belt base magnet device through the crown belt strip, thereby preventing the detection switch from detecting the signal and sending it back to the equipment PLC, causing the equipment to stop operating.
[0005] The specific technical solution in this application is as follows:
[0006] A tension protection structure for a crown belt device, comprising:
[0007] Support frame, installed on the support platform;
[0008] The guide rail assembly is detachably mounted on the support frame and is used for the up-and-down movement of the floating wheel assembly;
[0009] The floating wheel assembly includes a floating wheel and a floating wheel bracket. The floating wheel is mounted on the guide rail assembly via the floating wheel bracket. The floating wheel can rotate around the main wheel axle and can also move up and down along a predetermined track in the guide rail assembly to achieve the winding and conveying of crown belt material.
[0010] The magnet assembly is positioned above the floating wheel bracket and uses its own magnetic force to attract the floating wheel bracket to the top.
[0011] Furthermore, the guide rail assembly includes a guide rail and a stop, the stop being disposed at the lower part of the guide rail to limit the sliding range of the floating wheel assembly; the guide rail is mounted on the base plate and is detachably connected to the support frame through the base plate.
[0012] Furthermore, a slider is provided at the bottom of the floating wheel bracket. The slider matches the guide rail, and the slider drives the floating wheel assembly to slide up and down along the guide rail.
[0013] Furthermore, the stop is a plate structure with a concave longitudinal cross-section, and there is a movable distance between the highest end face of the stop and the lowest end of the guide rail.
[0014] Furthermore, a stop support is provided at the bottom of the stop, and the stop is fixedly connected to the stop support. The stop support is installed on the bottom of the base plate by fasteners.
[0015] Furthermore, the magnet assembly includes several magnets and a magnet base, the magnets being detachably mounted on the magnet base, and the magnet base being mounted on top of the substrate.
[0016] Furthermore, the magnet base plate is perpendicular to the substrate, and several magnets are evenly arranged on the end face of the magnet base plate near the floating wheel bracket. Under the action of the magnetic attraction of the magnets, the floating wheel bracket is located at the top.
[0017] Furthermore, it also includes a detection switch, which is mounted on the base plate via a switch bracket and is detachably connected to the base plate. The detection switch is used to detect whether the floating wheel bracket exists within a preset position range.
[0018] Furthermore, the detection switch is connected to the PLC signal of the crown belt device, and the PLC of the crown belt device controls the movement of the floating wheel assembly through signal output.
[0019] This utility model also discloses a crown band wrapping device, which is equipped with any of the crown band wrapping device tension protection structures described above.
[0020] This utility model provides a tension protection structure for crown belt devices, which has the following beneficial technical effects compared with the prior art:
[0021] The guide rail assembly enables vertical movement, while the magnet assembly ensures that the floating wheel assembly remains at the top position during normal operation. If the tension is too high, the magnet separates from the floating wheel support, and the detection switch cannot detect the presence of the floating wheel support. This triggers the safety protection mechanism of the equipment via the PLC, stopping the equipment from running. This prevents abnormal product performance due to unstable tension, protects the equipment from damage, and allows operators to adjust the tension protection structure in a timely manner, simplifying the maintenance process.
[0022] Applying the crown belt tension protection structure of this application to crown belt winding equipment can significantly improve the working performance and operational reliability of the equipment, while also helping to reduce maintenance costs and extend the service life of the equipment.

The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Combined with appendix Figure 1-4 As shown, a tension protection structure for a crown belt device includes:
[0033] Support frame 9 is installed on the support platform;
[0034] The guide rail assembly is detachably mounted on the support frame 9 and is used for the up-and-down movement of the floating wheel assembly;
[0035] The floating wheel assembly includes a floating wheel 1 and a floating wheel bracket 2. The floating wheel 1 is mounted on the guide rail assembly via the floating wheel bracket 2. The floating wheel 1 can rotate around the main wheel axle and can also move up and down along a predetermined track in the guide rail assembly to realize the winding and conveying of crown belt material.
[0036] The magnet assembly is located above the floating wheel bracket 2 and attracts the floating wheel bracket 2 to the top through its own magnetic force.
[0037] This application achieves vertical movement through a guide rail assembly, and the magnet assembly ensures that the floating wheel assembly remains in the uppermost position when there is no load or when the load is operating normally. This structural design helps protect the equipment from excessive tension and also simplifies the maintenance process of the device.
[0038] In some embodiments, combined with Figure 1 and Figure 4 As shown, the support frame 9 is a right-angled plate support structure. One end of the right-angled support frame 9 is connected to the substrate 10 to be supported, and the other end is fixed on the support platform.
[0039] In some embodiments, the guide rail assembly includes a guide rail 4 and a stop 5. The stop 5 is disposed at the lower part of the guide rail 4 and is used to limit the sliding range of the floating wheel assembly. The guide rail 4 is mounted on the base plate 10 and is detachably connected to the support frame 9 through the base plate 10.
[0040] Obviously, by setting the stop 5 to limit the sliding range of the floating wheel assembly, the system's safety and reliability are increased, ensuring that its movement does not exceed the safety limits. Meanwhile, the detachable connection between the base plate 10 and the support frame 9 facilitates the replacement and maintenance of components in the crown belt tension protection structure.
[0041] In some embodiments, a slider is provided at the bottom of the floating wheel bracket 2. The slider matches the guide rail 4, and the slider drives the floating wheel assembly (floating wheel 1 and floating wheel bracket 2) to slide up and down along the guide rail 4. The matching design of the slider and the guide rail 4 enables the floating wheel assembly to move smoothly up and down along the guide rail 4, improving the motion accuracy and stability of the entire mechanism.
[0042] In some embodiments, the stop 5 is a plate structure with a concave longitudinal cross section, and there is a movable distance between the highest end face of the stop 5 and the lowest end face of the guide rail 4.
[0043] In the design of the stop 5 structure, the concave plate structure of the stop 5 and the setting of the movement distance further enhance the precise control of the movement range of the floating wheel assembly, avoiding mechanical damage caused by excessive impact.
[0044] Furthermore, a stop support 8 is provided at the bottom of the stop 5, and the stop 5 is fixedly connected to the stop support 8. The stop support 8 is installed on the bottom of the base plate 10 by fasteners. Fixing the stop 5 to the base plate 10 by the stop support 8 not only enhances the stability of the overall structure, but also facilitates adjustment and maintenance.
[0045] For example, the maximum width of the stop 5 is greater than the width of the floating wheel bracket 2 so that the stop 5 can withstand the sliding of the floating wheel bracket 2. Furthermore, in order to buffer the damage caused by the floating wheel bracket 2 colliding with the stop 5 during its descent, an elastic protective layer can be provided on the upper surface of the stop 5.
[0046] In some embodiments, the magnet assembly includes a plurality of magnets 3 and a magnet base 7, wherein the magnets 3 are detachably mounted on the magnet base 7, and the magnet base 7 is mounted on the top of the substrate 10. The detachable design of the magnets 3 in the magnet assembly allows the magnetic force to be adjusted as needed to adapt to application scenarios with different tension requirements, thereby improving the adaptability and flexibility of the device.
[0047] Furthermore, the magnet base 7 is perpendicular to the base plate 10. Several magnets 3 are evenly arranged on the end face of the magnet base 7 near the floating wheel support 2. Under the magnetic attraction of the magnets 3, the floating wheel support 2 is located at the top. This structural design ensures the maximum attraction of the magnets 3 to the floating wheel support 2, effectively guaranteeing the stability of the floating wheel assembly under no-load conditions.
[0048] Those skilled in the art can select the number and size of the magnets 3 according to the specific characteristics of the floating wheel assembly (including but not limited to weight, shape, size, and other material characteristics). Furthermore, 3-6 magnets 3 can be provided. For example, see the attached... Figure 1 As shown, four magnets 3 are detachably installed on the bottom surface of the magnet base 7.
[0049] In some embodiments, the crown belt device tension protection structure further includes a detection switch 6, which is mounted on the base plate 10 via a switch bracket and is detachably connected to the base plate 10. The detection switch 6 is used to detect whether the floating wheel bracket 2 exists within a preset position range.
[0050] Obviously, by detecting the presence of the floating wheel bracket 2 within the preset position range through the detection switch 6, and by connecting the detection switch 6 to the equipment PLC for feedback control, the precise monitoring and automatic adjustment of the crown tension are achieved, thereby improving production efficiency and product quality.
[0051] Furthermore, the detection switch 6 is connected to the PLC of the crown belt equipment, and the PLC controls the movement of the floating wheel assembly through signal output. By receiving signals from the detection switch 6 and controlling the movement of the floating wheel assembly through the PLC, automated control is achieved, reducing manual intervention and improving the continuity and efficiency of production.
[0052] In specific applications, when the detection switch 6 fails to detect that the floating wheel bracket 2 is within the preset range, it will send corresponding information to the equipment PLC. After receiving the information, the PLC will determine that the tension of the crown strip is abnormal, thereby triggering safety measures, such as stopping the equipment or immediately stopping the winding process, to avoid further damage to the equipment or affecting product quality.
[0053] It should be noted that this utility model also discloses a crown band wrapping device, which is equipped with the crown band device tension protection structure in any of the above embodiments.
[0054] The working principle of the crown belt device tension protection structure proposed in this application is as follows:
[0055] Under normal operating conditions, the floating wheel assembly is held at the top position by the attraction force of the magnet 3. At this time, the floating wheel bracket 2 is within the normal preset range. The detection switch 6 can detect the presence of the floating wheel bracket 2 and feed the signal back to the PLC system of the equipment, so that the equipment can operate normally.
[0056] When abnormal tension occurs (excessive tension), the excessive tension acts on the floating wheel 1 and floating wheel support 2 through the crown strip, generating a downward pulling force. If this pulling force exceeds the attraction force provided by the magnet 3, the floating wheel support 2 will overcome the magnetic force and move downward. Once the attraction between the floating wheel support 2 and the magnet 3 is broken, the floating wheel support 2 begins to move downward along the guide rail 4, meaning it leaves the position previously detectable by the detection switch 6. As the floating wheel support 2 moves downward, the detection switch 6 can no longer detect its presence and sends corresponding information to the equipment PLC system via the signal connection. Upon receiving the abnormal tension signal, the equipment PLC system triggers the safety protection mechanism, stopping the equipment and halting the winding process.
[0057] Compared with the prior art, the above embodiments of this utility model have the following beneficial technical effects:
[0058] The guide rail assembly enables vertical movement, while the magnet assembly ensures that the floating wheel assembly remains at the top position during normal operation. If the tension is too high, the magnet 3 separates from the floating wheel bracket 2, and the detection switch 6 cannot detect the existence of the floating wheel bracket 2. This triggers the safety protection mechanism of the equipment through the PLC, causing the equipment to stop running. This prevents abnormal product performance due to unstable tension, ensures that the equipment is not damaged, and also makes it easier for operators to adjust the tension protection structure in a timely manner, simplifying the maintenance process.
[0059] Applying the crown belt tension protection structure of this application to crown belt winding equipment can significantly improve the working performance and operational reliability of the equipment, while also helping to reduce maintenance costs and extend the service life of the equipment.
[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
