Description
Technical Field
[0001] This utility model relates to the field of shaping equipment technology, and in particular to a steel strip support roller device for an anti-winding shaping machine. Background Technology
[0002] The working principle of a carpet yarn steam setting machine is mainly based on the thermal and humid effects of steam and specific process control. It optimizes the internal stress of the yarn, stabilizes its twist, and improves its physical properties. The yarn is wound and laid flat on a perforated steel belt, and continuously fed into a narrow, sealed setting chamber by rollers below the belt. Steam is transported to the setting chamber through pipes, and the steam heats and sets the yarn at a set temperature and time, allowing the yarn fibers to fully relax their twist, eliminate static electricity, and reduce internal stress. However, due to the hot and humid environment inside the chamber, the rollers supporting the perforated steel belt (0.25mm thick) often become entangled with yarn debris, and foreign matter enters the ball grooves of the roller bearings. This often causes the rollers to jam or even experience hard friction, resulting in wear and breakage of the conveying steel belt or burrs on the perforated mesh, which can easily irritate the yarn on the steel belt, seriously affecting the normal operation of the equipment. Furthermore, replacing the rollers in the sealed chamber requires stopping the machine to disassemble many parts, undoubtedly increasing maintenance time. Therefore, designing a stable and durable roller device is an urgent problem to be solved.
[0003] Current carpet setting machines use corrosion-resistant ball bearings to support the conveyor belt with a perforated steel strip. The ball bearings are radially fixed at both ends by left and right fixed plates with fixing screws, restricting their axial movement. Several main problems arise when operating the perforated steel strip: First, the setting chamber contains saturated steam, creating a hot and humid environment. Forced air circulation within the chamber allows yarn lint and short fibers to easily enter the rotating parts, especially the bearing balls. Due to the small clearance of the ball bearings, this can easily cause them to jam and become inflexible. Second, while the left and right fixed plates provide some stability, they can also easily entangle yarn, blocking the bearing's rotation. Therefore, a non-entanglement type of setting machine steel strip roller device is needed to solve these problems. Utility Model Content

[0006] Preferably, the right and left sliding sleeves are in sliding transition fit with the body shaft to ensure that the body shaft rotates flexibly without large clearance; the right and left sliding sleeves are made of EPX plastic, a self-lubricating material with good wear resistance.
[0007] Preferably, the left and right fixed baffles are designed as special irregular shapes to seal the inner cavities at both ends of the roller to prevent foreign objects from entering.

[0009] Compared with existing technologies, the advantages of this utility model are as follows: First, the device uses a material that remains self-lubricating in high temperature and high humidity environments, which improves the service life of the rotating parts (sliding sleeves), reduces equipment maintenance time, and improves equipment production efficiency; Second, the device prevents foreign objects from entering the roller body by designing a special irregular roller baffle, thus preventing internal blockage of the roller; Furthermore, the device is designed to reasonably restrict the three degrees of freedom of the roller, making the roller rotation more stable and flexible, avoiding damage to the mesh steel strip and other production losses.
