[0002] Cord is a material used for manufacturing tires. During the production process of tires, the cord is used to make the cord ply of the tire. The cord ply is a crucial component in the tire and plays a role in supporting and enhancing the strength of the tire inside. The design and layout of the cord ply have a direct impact on the performance of the tire. The number of layers, material type, and braiding angle of the cord ply will affect the durability, impact resistance, and operating stability of the tire.

[0034] 1. The cord fabric guiding and supporting device of the present utility model includes a guiding installation beam, a guiding installation frame, a guiding supporting shaft, a guiding supporting wheel, a guiding opening and closing shaft, a guiding moving member, a guiding rail assembly, a guiding limiting rod, and a guiding power assembly. The two ends of the guiding installation beam are adapted to be fixedly installed on a drum laminating machine. The guiding installation frame is fixedly installed at both ends of the guiding installation beam and has an arc-shaped installation portion. There are several guiding supporting shafts, which are uniformly and fixedly installed on the arc-shaped outer edge of the arc-shaped installation portion along the arc. There are several guiding supporting wheels, which are rotatably sleeved on the guiding supporting shafts and are used to support the cord fabric. The guiding opening and closing shaft is rotatably installed on the guiding installation frame and includes a first guiding opening and closing shaft with a first spiral direction and a second guiding opening and closing shaft with a second spiral direction, and the spiral directions of the first spiral direction and the second spiral direction are opposite. There are two guiding moving members, which are respectively rotatably installed on the first guiding opening and closing shaft and the second guiding opening and closing shaft. The guiding rail assembly is installed between the guiding moving member and the guiding installation beam and is used to limit the rotation of the guiding moving member. There are several guiding limiting rods, which are uniformly fixedly installed on the guiding moving member and extend outward a certain length from the gap between the two guiding supporting shafts. The guiding power assembly is arranged outside the guiding installation frame and is used to drive the guiding opening and closing shaft to rotate, and then drive the guiding limiting rod to perform an opening and closing movement.

[0035] When automatically feeding materials using the cord fabric guiding and supporting device of the present utility model, the cord fabric is unfolded and laid on the guiding supporting wheels of the guiding and supporting device and guided to the conveyor belt of the laminating machine, and the cord fabric is pressed against the conveyor belt using a pressing wheel.

If the cord fabric is not in the middle position, after the guiding limiting rod on one side guiding moving member contacts the cord fabric, it will push the cord fabric towards the guiding limiting rod on the other side guiding moving member until the two side edges of the cord fabric contact the guiding limiting rods on the two side guiding moving members. At this time, the cord fabric is adjusted to the specified position. The cord fabric guiding and supporting device of the present utility model can adapt to the width change of the cord fabric by driving the two side guiding moving members to move towards each other or away from each other, and can push the cord fabric to the middle position through the guiding limiting rods, without manual pulling and adjustment, which can improve production efficiency and reduce labor intensity.

[0036] 2. In the cord fabric guiding and supporting device of the present utility model, the guiding moving member is provided with internal threaded holes, which are respectively threadedly connected to the first guiding opening and closing shaft and the second guiding opening and closing shaft.

[0037] 3. The curtain guide and support device of the utility model, the guide rail assembly includes a guide rail and a guide slider; wherein the guide rail is fixedly mounted on the guide mounting beam, and its extension direction is parallel to the axial direction of the guide opening and closing shaft; the guide slider is fixedly mounted on the guide movable member, and slidingly cooperates with the guide rail; when the guide opening and closing shaft rotates, the guide movable member is restricted by the guide rail assembly and cannot follow the rotation, and can only move along the extension direction of the guide rail; the opening and closing degree numerical scale line is set on one side wall of the guide rail, and the movement of the guide movable member drives the guide slider to move on the guide rail, and when the guide movable member stops moving, the position corresponding to the opening and closing degree numerical scale line can indicate the moving distance, thereby helping workers to clearly identify the designated position for curtain feeding.

[0038] 4. The curtain guide supporting device of the utility model, the guide power assembly includes a guide driven rotor, a guide driving rotor, a power piece, a guide driving wheel mounting seat, a guide driving wheel shaft and an operating ring; wherein the guide driven rotor is mounted on one end of the guide opening and closing shaft that passes through the guide mounting frame; the guide driving rotor is rotatably mounted on the outside of the guide mounting frame, and is connected to the guide driven rotor through a guide belt; the power piece is used to drive the guide driving rotor to rotate, and drives the guide opening and closing shaft to rotate through the guide belt and the guide driven rotor; the guide driving wheel mounting seat is fixedly mounted on the outside of the guide mounting frame; the guide driving wheel shaft is rotatably mounted on the guide driving wheel mounting seat, and the guide driving wheel is fixedly mounted on the guide driving wheel shaft; the operating ring is fixedly mounted on the guide driving wheel shaft, and is located on the inner side or outer side of the guide driving wheel.

[0039] When the position of the curtain needs to be adjusted, the operating ring is rotated. The operating ring drives the guide active wheel to rotate through the guide active wheel shaft, and drives the guide driven wheel to rotate through the guide belt, thereby driving the guide opening and closing shaft to rotate; the rotation of the guide opening and closing shaft drives the two guide moving parts to move closer to or away from each other, adjusting the opening and closing degree to adapt to the width of the curtain, and can push the curtain to the specified position through the guide limit rod.
