Problems solved by technology

[0002] In the post-spinning process of the chemical fiber industry, the tow is stretched through various drafting machines and oil and water baths. During the stretching process, the tow is improved by having a larger wrap angle with each roller. The friction between the tow and the drafting rollers is used to pull the tow by the friction of multiple rollers. After the tow passes through the first drafting machine, it enters the high-temperature oil tank for heating, and then the faster drafting speed of the second drafting machine will be at The tow in the oil tank is stretched, and then enters the high-temperature water tank, and then the tow in the water tank is stretched by three drafts at a faster drawing speed, but now the tows pass through each other and the roller If the tension control is realized by the friction force between the tow and the drafting roller, it is impossible to prevent the displacement between the tow and the drafting roller. quality

Abstract

The invention relates to a drafting machine device with stable tow draft ratio. The drafting machine device with the stable tow draft ratio comprises a panel and drafting rollers, wherein the drafting rollers in a tow passing direction are a first roller, a second roller, a third roller, a fourth roller, a fifth roller, a sixth roller and a seventh roller, the first roller, the third roller, the fifth roller and the seventh roller are arranged on the lower row, the second roller, the fourth roller and the sixth roller are arranged on the upper row, the fourth roller is a self-locking roller, a rubber ring is arranged on the exterior of the fourth roller, the fourth roller is respectively in friction type contact with the third roller and the fifth roller, an air cylinder is arranged on the panel, and the axial heads of the two ends of the fourth roller are respectively connected with a piston rod of the air cylinder through hinges. When the drafting machine device with the stable tow draft ratio is used, the displacement between tows and rollers can be basically eliminated, so that the tow draft ratio is stable; the drafting machine device has the characteristics of simple structure and convenience and safety in use.
