Description

Technical Field

[0001] The utility model belongs to the technical field of rubber processing, and in particular relates to a wide-width cord fabric winding and turnover device. Background Art

[0002] The carcass ply of bias tires is composed of multiple layers of rubber cords. According to the construction standards, the rubber cords cut and wound up need to be made into multi-layer annular cord tubes on a special laminating machine. The cord width of large-sized tires currently produced, especially engineering machinery tires, exceeds 1.5 meters, and the widest can be close to 2 meters. Using the existing cord winding method, the cord roll is too heavy and difficult to carry. The use of overhead cranes has great limitations and complicated turnover, and it is impossible to deliver the cord roll to the laminating machine supply rack at one time.

[0003] The giant tire carcass cord winding device with patent application number CN204607164U includes a base, a cord winding device, a mobile trolley and a locking mechanism; when the mobile trolley moves along the base until the cord I-shaped wheel is coaxially docked with the cord winding mechanism and the padding I-shaped wheel is coaxially docked with the padding brake mechanism, the locking mechanism locks the mobile trolley and the head mechanism into one. The cord winding mechanism of the above device cannot ensure the tension of the cord during the winding process, and the winding result may be poor. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a wide-width cord fabric winding and turnover device in view of the deficiencies of the above-mentioned prior art, which reduces the difficulty of carrying and turnover of wide-width cord fabric rolls, improves production efficiency and reduces labor intensity.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A wide-width curtain fabric winding and turnover device comprises a bracket, a mounting plate, a cloth feed roller, a guide roller, a cloth expansion roller and a curtain fabric roller, wherein the mounting plates are mounted at both ends of the bracket, the guide roller is fixed above the mounting plate in parallel with the cloth feed roller, the cloth expansion roller is mounted below the guide roller and fixed between the mounting plates, and the curtain fabric roller comprises a first curtain fabric roller and a second curtain fabric roller, and the first curtain fabric roller and the second curtain fabric roller are fixed at the bottom of the bracket in parallel.

[0007] Furthermore, a device frame is provided at the bottom of the bracket, the device frame is connected and fixed to the bracket by bolts, and a plurality of universal wheels are provided at the bottom of the device frame.

[0008] The universal wheels set at the bottom of the device frame make the entire wide-width cord winding and turnover device have good mobility. Without the help of additional handling tools, the staff can easily change its position in the workplace to adapt to different production line layouts and process requirements. Although it is equipped with universal wheels for easy movement, the device frame and bracket are fixed by bolts to ensure that when the equipment is in normal use, it can maintain sufficient stability and bearing capacity to avoid the instability caused by equipment movement affecting the accuracy and safety of cord winding work. When long-term fixed use is required, the position of the equipment can be fixed by locking the universal wheels; when the layout needs to be temporarily adjusted, the equipment can be easily moved by unlocking the universal wheels, which reflects a high degree of flexibility and practicality. The design of the universal wheels reduces the wear and tear that may be caused by directly dragging the equipment on the ground, and protects the floor environment of the workshop. Due to its mobility, the device can be quickly moved to an idle area when not in use, effectively saving valuable production space.

[0009] Furthermore, the device frame is composed of two long axes and two short axes, the long axes and the short axes are both made of square tubes, and the bracket is installed on the long axes.

[0010] Compared with round tubes, square tubes have higher structural rigidity when bearing loads perpendicular to the tube surface, and can provide better resistance to bending and torsion, thereby enhancing the overall stability and load-bearing performance of the device frame. The quadrilateral cross-section of the square tube has a larger contact area when connected to other components (such as brackets), and the connection with fasteners such as bolts is more secure and reliable, and is not prone to loosening or slipping. The internal space of the square tube can be used as a channel for cables, pipes or other accessories, which is conducive to organizing internal wiring or arranging related accessories, improving space utilization and overall aesthetics. The right-angle structure of the square tube is easy to process and position and cooperate with other standard size parts, simplifying the production and assembly process of the device frame. The square tube structure can prevent deformation caused by uneven force, especially when supporting heavy loads, and can better ensure the safety of operators.

[0011] Furthermore, two bearing seats are respectively arranged on the short shafts, a fixed ring is arranged inside the bearing seat, the first curtain roller and the second curtain roller are connected to the fixed ring, an end shaft is also arranged at the outer end of the bearing seat, a coupling is installed on the end shaft, and the coupling connects the first curtain roller and the second curtain roller.

[0012] The fixed ring in the bearing seat can accurately control the position and rotation center of the curtain roller, ensuring high concentricity when the curtain roller is running, avoiding vibration and noise caused by eccentricity, and also reducing the risk of deviation of the curtain during winding. The bearing seat and the bearing design inside it can greatly reduce the friction resistance when the curtain roller rotates, thereby reducing mechanical wear and extending the service life of the curtain roller and bearings. The curtain roller is fixed by the bearing seat, making it more convenient to replace or repair the curtain roller. It only needs to remove the corresponding bearing seat and coupling, which improves the efficiency of equipment maintenance. The coupling installed on the end shaft can effectively transmit power to the two curtain rollers to achieve synchronous rotation, which is crucial for the parallel winding operation of the double curtain rollers, ensuring the uniformity and stability of the curtain winding. This design makes the entire device compact and fully utilizes the space. At the same time, the various components work together to improve the overall working efficiency of the equipment.

[0013] Furthermore, the guide roller and the cloth feed roller are hollow rollers, and the cloth expansion roller is a solid tube; the first curtain roller and the second curtain roller are both wooden shafts, and square steel is arranged inside the wooden shaft. The first curtain roller and the second curtain roller are connected to the fixed ring through the square steel, and the first curtain roller and the second curtain roller are fixed to the device frame through the fixed ring.

[0014] Compared with solid rollers, hollow rollers are lighter, which reduces the overall weight of the equipment, reduces energy consumption, and also reduces the burden on the motor drive. Without affecting the structural strength and performance, the hollow roller design can save more material resources. The solid tube provides higher structural rigidity and stability, and can maintain a better shape during the fabric expansion process, ensuring that the fabric is evenly and smoothly unfolded. The wooden shaft has a certain elasticity and can absorb part of the impact from the tension of the curtain cloth, reduce vibration and noise, and protect the curtain cloth from damage. The square steel embedded in the wooden shaft can greatly improve the axial bearing capacity and torsional strength of the curtain cloth roller, ensuring that when winding thicker or harder curtain cloth, the curtain cloth roller can work stably without breaking or deformation. The curtain cloth roller is connected to the device frame through the internal square steel, which not only retains the excellent characteristics of the wooden shaft, but also achieves effective fixation with the metal device frame through the square steel, ensuring the stability and durability of the equipment during operation.

[0015] The utility model has the following beneficial effects:

[0016] 1. This device can be used in combination with the cutting and winding machine and the cloth supply rack. It is fixed with the cutting and winding machine during cutting and connected with the cloth supply rack during laminating. The curtain cloth roll and the pad cloth roll are automatically wound up and can be used alternately in the cutting and laminating processes, avoiding manual handling, no need to unload the roll, fast roll change, reducing labor intensity, and improving the efficiency of cloth winding, turnover and transportation;

[0017] 2. The wide-width cord winding and turnover device is specially designed for the wide-width cord processing in large-size tire manufacturing. It can effectively meet the special needs of large-size cord winding, turnover and use. The design of parallel fixed feed roller and guide roller enables the cord to maintain a constant speed and direction during the winding process, reducing the misalignment and distortion of the fabric, greatly improving the winding efficiency. The expansion roller is located below the guide roller, which can fully flatten and pre-tension the cord before winding, ensuring that the cord is flat and wrinkle-free after winding, which is beneficial to the uniform laying and bonding quality of the tire cord layer.
