Description

Technical Field

[0001] This invention relates to the field of tire production auxiliary equipment technology, and in particular to a zero-degree steel wire crown belt coiling production equipment. Background Technology

[0002] In the production process of zero-degree steel wire crown belts, in order to facilitate the rapid transfer, storage and feeding of the produced zero-degree steel wire crown belts, coiling production equipment is usually used to coil the continuous strip of zero-degree steel wire crown belts after coating with glue, which greatly improves logistics and forming efficiency. Existing coiling production equipment usually consists of I-beam rollers, tension rollers, padding guide devices and bonding rollers.

[0003] For example, utility model application CN201920866499.2 discloses a material storage device and a production line for manufacturing steel wire crown belts. Specifically, it includes a frame and at least two sets of material storage components arranged within the frame. The at least two sets of material storage components are arranged sequentially upstream and downstream along the conveying direction of the steel wire crown belt. The frame includes a support arranged between two adjacent sets of material storage components. The support is provided with a clamp assembly for fixing the material head of the steel wire crown belt. This utility model also provides a production line for manufacturing steel wire crown belts with the above-mentioned material storage device. Thus, this utility model has the advantages of high winding efficiency and low labor cost.

[0004] However, conventional material storage mechanisms mostly adopt a counterweight passive floating roller structure. The tension adjustment of the counterweight structure relies on the up and down floating stroke of the floating roller. When the floating roller is at different stroke positions, the wrapping angle and force direction of the material will change accordingly. However, the gravity output of the counterweight is constant, which will cause the actual tension value acting on the material to fluctuate with the change of the storage amount. This will cause uneven fluctuations in the width and thickness of the same crown strip along the length direction, exceeding the tolerance range required by the tire manufacturing process. At the same time, it will also reduce the dimensional consistency of the same batch of products and increase the probability of quality deviation. Summary of the Invention

[0005] In view of this, the present invention provides a zero-degree steel wire crown band coiling production equipment, which has the characteristics of realizing real-time tension detection and closed-loop adjustment, improving tension stability under multi-stage speed fluctuations, and adapting to the tension control requirements of materials of different specifications.

[0040] The specific usage and function of this embodiment: In this invention, the wire traction roller 102 is started by the drive motor 101, so that the wire traction roller 102 generates tension on the zero-degree wire crown strip and pulls it. The setting of the wire guide roller 103 can increase the wrap angle of the wire traction roller 102, ensuring the traction force of the wire traction roller 102 on the zero-degree wire crown strip. The pulled zero-degree wire crown strip is wound onto the upper wire floating roller 108 and the lower wire floating roller 105. The upper wire floating roller 108 can be raised and lowered by the transmission of the first cylinder chain lifting assembly 106, and then the upper wire floating roller... The raising and lowering of roller 108 creates separation and closing forces between the upper and lower floating rollers 108 and 105, pulling the zero-degree steel wire crown strip wound on them and generating tension. Simultaneously, the raising and lowering of the upper floating roller 108 adjusts the distance between it and the lower floating roller 105, controlling the amount of zero-degree steel wire crown strip stored on them. The tilting seat 107 keeps the upper floating roller 108 tilted, creating a tension between it and the lower floating roller 105. The fixed included angle causes the zero-degree steel wire crown strip wound between the upper steel wire floating roller 108 and the lower steel wire floating roller 105 to spirally wind, generating a certain spiral angle. This allows the material to flow along a smooth spiral line throughout the entire process, without any reverse bends or local small-radius bends. The bending radius is uniform and sufficiently large, and the steel wire and rubber layer are not subjected to bending stress throughout the process, perfectly avoiding the core risk of material damage. The output end of the zero-degree steel wire crown strip wound on the upper steel wire floating roller 108 and the lower steel wire floating roller 105 is passed through the tension control component 109. The tension sensor outside the tension control component 109 can detect the zero-degree steel wire crown strip in real time. The tension of the wire crown strip is controlled, and if the tension is too high or too low, a signal is transmitted to the external control program to activate the first cylinder chain lifting assembly 106. This adjusts the distance between the upper wire floating roller 108 and the lower wire floating roller 105, thereby adjusting the tension. The external control program is a production line control program commonly used by those skilled in the art, and therefore will not be described in detail here. The zero-degree wire crown strip passing through the tension control assembly 109 will pass through the wire anti-reverse assembly 110. The anti-reverse pressure plate inside the wire anti-reverse assembly 110 clamps the head of the zero-degree wire crown strip, preventing the head from being pulled out after the zero-degree wire crown strip breaks.The zero-degree steel wire crown strip, after passing through the steel wire anti-reverse assembly 110, will pass through the smooth rod cable guide 117 and wind onto the crown strip winding assembly 118. At this time, activating the crown strip winding assembly 118 will wind and coil the zero-degree steel wire crown strip. During the winding and coiling process, the control motor 112 can be activated, causing the control motor 112 to drive the first pulley 113 to rotate. The rotation of the first pulley 113 will cause the second pulley 114 to rotate via the transmission belt. The rotation of the second pulley 114 will drive the control screw 115 to rotate. The rotation of the control screw 115 will drive the control slide 116 to move. The movement of the control slide 116 will drive the smooth rod cable guide 117 to move. The movement of the smooth rod cable guide 117... The zero-degree steel wire crown strip is repeatedly wound onto the crown strip winding assembly 118 at a certain pitch. The padding unwinding assembly 119 allows for convenient active rotation and unloading of the padding material roll via a motor drive, exporting the padding material. The exported padding material is guided by the padding guide frame 120 and continues to be output. As the padding material passes the padding guide frame 120, the padding monitoring sensor 121 detects the presence or absence of padding material within the guide frame 120. The padding material passing through the guide frame 120 passes through the padding anti-reverse assembly 122. When the padding monitoring sensor 121 detects no padding material, it transmits a signal to the external control program, activating the anti-reverse pressure plate to press down and clamp the tail of the padding material, preventing it from being pulled out. The anti-reverse pressure plates mentioned in this application are all pneumatically or hydraulically driven.

[0041] Example 2: Based on Example 1, please refer to Figures 8 to 9 As shown, it includes: a second cylinder chain lifting assembly 124, a lower padding cloth floating roller 125, and an upper padding cloth floating roller 126. The second mounting frame 123 is provided with the second cylinder chain lifting assembly 124, which consists of a cylinder, a chain, and a slide. The lower padding cloth floating roller 125 is fixedly connected to the lower part of the second mounting frame 123. The upper padding cloth floating roller 126 is fixedly connected to the outside of the slide of the second cylinder chain lifting assembly 124.

[0042] The specific usage and function of this embodiment: In this invention, the padding cloth passing through the padding cloth anti-reverse assembly 122 is alternately wound onto the lower padding cloth floating roller 125 and the upper padding cloth floating roller 126. The upper steel wire floating roller 108 can be raised and lowered by the transmission of the second cylinder chain lifting assembly 124. The raising and lowering of the upper padding cloth floating roller 126 will cause the distance between the lower padding cloth floating roller 125 and the upper padding cloth floating roller 126 to change. As the distance changes, a separating tension will be generated, which will generate tension on the padding cloth. At the same time, by controlling the distance between the lower padding cloth floating roller 125 and the upper padding cloth floating roller 126, a certain amount of material storage can be adjusted. The output padding cloth will be wound together with the zero-degree steel wire crown strip onto the crown strip winding assembly 118, so that the padding cloth separates the two adjacent crown strips, preventing interlayer adhesion. At the same time, the uniform padding support will offset the interlayer compression caused by the winding tension, avoid the deformation of the rubber material due to cold flow, and ensure that the width and thickness of the crown strip meet the process requirements throughout the process.
