Abstract
Description
Technical Field
[0001] The utility model relates to the field of tire production tools, in particular to a cord fabric tube storage vehicle with an arc-shaped universal ball structure. Background Art
[0002] As we all know, in the field of tire manufacturing, tires can be divided into bias tires and radial tires in terms of structural design. Bias tires, also known as ordinary structural tires, refer to pneumatic tires in which the adjacent layers of carcass cords and buffer layers are crossed and arranged at an angle less than 90° to the center line of the tread. The structure of bias tires includes tread, cord layer, buffer layer, bead and other components. The cord layer is the skeleton of the tire, also known as the carcass. Its main function is to bear the load, maintain the shape and size of the tire, and make the tire have a certain strength. The cord layer is usually made of multiple layers of rubber cords bonded with rubber. Its production process is that the layer machine laminates the cord layer and the buffer layer in multiple layers according to the angle and direction of the process standard. After the lamination is completed, the cord tube is removed and stored on a special storage vehicle, and then assembled and molded in a molding machine. Since the cord material generally includes cotton thread, rayon thread, nylon thread and fiber thread, improper storage is very likely to cause local tensile deformation, affecting the load-bearing capacity of the tire and seriously affecting the service life of the product.
[0003] After the layers of fabric are completed, the cord tube is directly stored on a right-angled triangle bracket storage vehicle made of round tubes. Since the weight of the multiple layers of cord increases after being pasted, it is stored on the round tube bracket. Due to the small contact surface, the force on the stress point increases, resulting in severe stretching of the stressed part, which directly causes the cord strength in this part to decrease. When loading and unloading, the cord tube must be lifted and there must be enough gap between it and the round tube bracket, which is not conducive to position adjustment during on-site quality inspection, has high labor intensity, and the stretched part causes reduced load-bearing capacity, leading to hidden dangers such as early tire damage. Summary of the invention
[0004] In order to overcome the deficiencies of the prior art, the utility model provides a curtain cloth roll storage vehicle with an arc-shaped universal ball structure, which effectively prevents the problem that the original contact surface is small and the stress point is subjected to large stress, resulting in severe stretching of the stressed part, which directly causes the curtain cloth strength in this part to be reduced.
[0005] The technical solution adopted by the utility model to solve its technical problems is: an arc-shaped universal ball structure curtain cloth tube storage vehicle, which is provided with a base frame, two sets of self-locking steering wheels and self-locking steering wheels are respectively installed at the two ends below the base frame, a supporting vertical frame is provided in the middle of the base frame, an upper supporting frame is installed at the upper position of the supporting vertical frame, and the vertical supporting frame is vertically connected with the upper supporting frame. It is characterized in that an arc-shaped supporting frame is provided above the vertical supporting frame, a universal ball fixing bracket is installed above the arc-shaped supporting frame, and the universal ball assemblies are evenly distributed and installed on the universal ball fixing bracket, the supporting vertical frame is reinforced and connected with the base frame through a reinforcing supporting frame, and the far end of the vertical supporting frame is supported and connected with the reinforcing supporting frame through a strength supporting frame.
[0006] The beneficial effects of the utility model are that friction is reduced, installation and removal are flexible, and the problem of small contact surface and large force on the force-bearing point, which leads to severe stretching of the force-bearing part and directly causes the cord strength of the part to be reduced, is effectively prevented, the uniformity of the cord tube strength is improved, and the hidden danger of early tire damage is eliminated.

DETAILED DESCRIPTION
[0011] In the figure, the utility model is provided with a base frame 1, two sets of self-locking steering wheels 2 and self-locking steering wheels 3 are respectively installed at the two ends below the base frame 1, a supporting frame 4 is provided in the middle of the base frame 1, and the supporting frame 4 is reinforced and connected with the base frame 1 through a reinforcing support plate 5, an upper supporting frame 6 is installed at the upper position of the supporting frame 4, a reinforcing supporting frame 7 is installed at the middle position of the supporting frame 4, a vertical supporting frame 8 is vertically welded to the upper supporting frame 6, an arc-shaped supporting frame 9 is provided above the vertical supporting frame 8, a universal ball fixing bracket 10 is installed above the arc-shaped supporting frame 9, and a universal ball assembly 11 is evenly distributed and installed on the bracket, and is connected to the vertical supporting frame 8 by connecting a fastening wire 12. In order to prevent the vertical supporting frame 8, the arc-shaped supporting frame 9 and the universal ball fixing bracket 10 from being deformed due to gravity, the distal end of the vertical supporting frame 8 is supported and connected with the reinforcing supporting frame 7 through a strength supporting frame 13.
[0012] After the utility model is put into use, the specific operation plan is that the operator places the produced cord tube on the vertical support frame 8, the arc support frame 9 and the universal ball fixing bracket 10, and by pulling the cord tube, the cord tube is easily hung for storage under the rolling force of the universal ball assembly 11. Since the arc support frame 9 is widened, the pressure of the original single-point force is evenly distributed. When the storage vehicle is stored, the self-locking steering wheel 2 and the self-locking steering wheel 3 are released, and the vehicle is pushed to the molding area for molding operation. During the molding process, the cord tube is reversed from the vertical support frame 8, the arc support frame 9 and the universal ball fixing bracket 10. On the ball fixing bracket 10, by pulling the cord tube, the cord tube can be easily taken out and formed under the rolling force of the universal ball assembly 11. If the cord tube needs to be quality inspected on site, it is only necessary to easily turn the cord tube to a certain position, which completely eliminates the disadvantage that the cord tube can only be moved after being lifted up and separated from the round tube storage rack by a certain distance, thereby completing the loading and unloading action and recycling it, effectively preventing the original small contact surface and large force on the stress point, resulting in severe stretching of the stress-bearing part, which directly causes the problem of reduced cord strength at that part, thereby improving the uniformity of the cord tube strength and eliminating the hidden dangers of early tire damage.
