Description

Technical Field

[0001] The utility model belongs to the technical field of insulating tube blank passing, in particular to an insulating tube untwisting blank passing production line. Background Art

[0002] During the production of insulating hoses, glass fibers are often woven into tubes, and a soft insulating varnish is applied to the outer surface of the woven tubes, which is then cured to form insulating hoses. These hoses are mainly used for various joints and high-voltage turn-to-turn insulation. The production of insulating hoses is divided into two main processes: tube weaving and insulating varnish coating, and each is an independent continuous production process. In the varnish coating process, due to the vertical coating process, the glass fiber tubes are required to be in a rounded state before coating. The tubes woven from glass fiber yarns are soft, especially those with large diameters. Due to the influence of gravity, they will become flat rather than cylindrical. In order to make the tube cylindrical, the tubes need to be rounded before coating, which is commonly known as "through-the-tube" process.

[0003] Most existing billet-passing devices use three billet-passing wheels and billet-passing rods to pass the billet tubes. The billet-passing rods are generally "M"-shaped or "J"-shaped. Under the driving friction of the billet-passing wheels, the billet tube slowly passes through the billet-passing rod head with a larger diameter, thereby realizing a full-circle process. The driving force is provided by friction between the billet tube and the billet-passing wheels. Slippage is likely to occur between the billet tube and the billet-passing wheels, which requires workers to deal with in a timely manner, affecting production efficiency and increasing additional labor input.

[0004] In addition, some billet tubes may be twisted after coming out of the barrel, and workers need to correct and untwist them in time, otherwise it will affect the flow of the billet. Utility Model Content

[0005] The utility model provides a production line for untwisting and straightening insulating tube blanks, which can solve the problems pointed out in the background technology.

[0006] An insulating tube untwisting and billet passing production line comprises a untwisting frame assembly and a billet passing assembly arranged in sequence, wherein the untwisting frame assembly comprises at least one set of untwisting shaft assemblies, wherein the untwisting shaft assembly comprises three untwisting shafts arranged at different heights, and the three untwisting shafts are distributed in a triangular pattern;

[0007] The blank passing assembly includes a feeding and stretching wheel, a first blank passing wheel, a second blank passing wheel, a third blank passing wheel and a blank passing rod arranged in sequence. The feeding and stretching wheel is arranged lower than the first blank passing wheel so that the feeding and stretching wheel provides a certain traction and stretching force.

[0008] Preferably, the feeding and stretching wheel is a power input wheel, which is connected to the third blank wheel through a gear, the second blank wheel is connected to the third blank wheel through a gear, and the first blank wheel and the third blank wheel are connected through a synchronous belt.
