Description

Technical Field

[0001] This utility model relates to an improvement of a tire production device, specifically a tire cord continuous uniform speed winding device. Background Technology

[0002] Tire cord fabric is the material used in the ply layer of a tire. It is a composite structure combining fabric and rubber. After the materials are bonded, the tire cord fabric is cut into strips with beveled edges. During production, the tire cord fabric needs to be sequentially spliced ​​and then rolled up to facilitate feeding to the tire forming machine in the subsequent process. Therefore, conventional cord fabric winding equipment does not operate continuously but uses an intermittent start-stop method, specifically a "one sheet at a time" winding method. In this working mode, the drive motor needs to start and stop frequently, and it is not easy to coordinate with the frequency of material intake. At the same time, the vibration of the motor during start-stop is large, the instantaneous current generated is also large, and additional mechanical losses will occur. For tire cord fabric, the uneven tension during winding and the large changes in friction result in large tension fluctuations, which can easily damage the tire cord fabric itself, causing irreversible deformation and breakage. Therefore, the winding equipment needs to be improved. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned deficiencies in the prior art and to provide a tire cord fabric continuous uniform speed winding device.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The winding device includes a feeding buffer structure, a winding structure, and a winding drive structure. The tire cord first enters the feeding buffer structure and hangs naturally there. After passing through the feeding buffer structure, the tire cord is wound into the winding structure. The winding structure is controlled by the winding drive structure to change its rotation speed. The feeding buffer structure is equipped with a hanging height sensing device to sense the hanging height of the tire cord. The hanging height sensing device is controllably connected to the winding drive structure. This device has a feeding buffer structure, which can buffer the discontinuity of feeding in this section, making the overall winding speed uniform. The winding structure is controlled by the winding drive structure to achieve controllable and adjustable speed, reducing the tension on the tire cord. The basis for controlling the winding speed is the hanging height sensing device. The hanging part of the cord is the allowance. The winding speed is adjusted according to the amount of allowance. The adjustment process is gradual and tends to be uniform, so it will not damage the tire cord structure.

[0005] Furthermore, the feeding buffer structure includes a spatial limiting frame, which divides the space into a buffer space for the tire cord to hang naturally. A guide roller is installed at the top of the spatial limiting frame. The tire cord passes through the guide roller at the top of the spatial limiting frame, and the remaining portion hangs naturally within the buffer space. The spatial limiting frame forms a space for the tire cord to hang naturally without external pulling, and its structure is simple and reliable, providing a certain degree of spatial structural protection.

[0006] Furthermore, the suspension height sensing device includes at least an upper limiter, a lower limiter, and a middle limiter, which are fixed to the spatial limiting frame according to their relative height positions. When the upper limiter is triggered, it decelerates the winding drive structure; when the lower limiter is triggered, it accelerates the winding drive structure; and when the middle limiter is triggered, it maintains a constant speed for the winding drive structure. When the upper limiter is triggered, it indicates that the tire cord's winding allowance is insufficient and will cause pulling on the cord, thus requiring deceleration. When the lower limiter is triggered, it indicates that the tire cord's winding allowance is excessive and will cause interference, thus requiring acceleration. After acceleration or deceleration compensation, the middle limiter is triggered, and the winding speed is adjusted to a normal constant speed, allowing for stable winding at a prolonged period.

[0007] Furthermore, the upper limiter, lower limiter, and middle limiter all employ photoelectric sensors. Each photoelectric sensor has a transmitting end and a receiving end, and is laterally fixed to the spatial limiting frame on both sides of the buffer space. By using photoelectric sensors to cover sensing areas at different heights, the position of the tire cord fabric is precisely sensed, providing a basis for speed compensation of the winding drive structure, achieving a uniform and efficient winding effect.

[0008] Furthermore, the winding drive structure is a servo motor, which is fixed on the support of the winding structure and rotatably connected to the winding roller through a transmission structure. The controller of the servo motor is connected to the suspension height sensing device circuit. The winding drive is a servo motor, which has high adjustable precision and good controllable sensitivity, making it convenient for operation and debugging. The support of the winding structure also has a winding radius sensor, which senses the radius change of the tire cord roll being wound and provides a basis for adjusting the speed of the servo motor. The winding radius sensor can be a laser sensor.

[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is an improvement on the winding device of tire cord fabric, which can change the segmented winding of the cord fabric into a uniform winding working state. It can be set between the splicing device and the final winding device of the tire cord fabric to achieve a controllable winding effect, improve the product precision of tire cord fabric, and improve the efficiency of production and processing.
