Description

Technical Field

[0001] The utility model relates to a plastic strapping belt drawing roller, belonging to the technical field of drawing rollers. Background Art

[0002] The principle of the strapping tape drawing roller is to use friction and pressure to stretch and shape the strapping tape. When the strapping tape passes through the drawing roller, friction is generated between the roller surface and the strapping tape. The strapping tape is stretched and formed by the rotation of the roller. The rotating shaft is a hollow shaft, and a heat exchange interlayer is provided in the roller body. The oil circulation is realized through the oil inlet and return holes, which improves the utilization rate of the hot oil and reduces the hot oil capacity in the roller body.

[0003] When multiple strapping tapes need to be processed, they are prone to getting entangled with each other on the drawing rollers, which will affect the forming effect of the strapping tapes. At the same time, after the strapping tapes are formed, they still have a high temperature, so they are usually passed through a water tank to quickly cool them down. However, this cooling method will keep the strapping tapes in a wet state, and it will take time to dry them later, which is troublesome. Utility Model Content
