Improved structure of drafting device in ribbon lap machine

Abstract

An improved structure of a traction device in a strip ribbon lap machine which consists of a supporting plate, a first roller seat, a second roller seat, a first metal roller, a second metal roller and a third metal roller. The first roller seat and the second roller seat are arranged on the supporting plate; the first metal roller and the second metal roller are arranged on the first roller seat; the third metal roller is arranged on the second roller seat; the lower end of the supporting plate is provided with a large rocker by a first lower supporting rod and a shaft; the lower end of the second roller seat is provided with a small rocker by a second lower supporting rod and one shaft; a first pressurizing air cylinder is arranged on the large rocker; a second pressurizing air cylinderis arranged on the small rocker; the first pressurizing air cylinder and the second pressurizing air cylinder are respectively connected with a first robber roller and a second rubber roller. The improved structure of a traction device improves the layout structure of the metal rollers and the rubber rollers; two independent pressurizing air cylinders are adopted to respectively carry out pressurizing on the rubber rollers; the mechanism has simple structure, is convenient for adjusting the working parameters; besides, the sliver traction effect is improved.

Description

Technical field: [0001] The invention relates to the field of machinery, in particular to textile machinery, in particular to a sliver doubling machine, and in particular to an improved structure of a drafting device in the sliver doubling machine. Background technique: [0002] In the prior art, the sliver doubling machine adopts a drafting pattern of four up and four down, or three up and three down, or two up and three down. The four-up and four-down drafting structure is composed of four rubber rollers of the same diameter and four metal grooved rollers of the same diameter. There are three drafting areas. The drafting device has an included angle with the horizontal, and is composed of a support plate on one side. The flip angle of the support and opening device is less than 90°, and the air bag is used to realize the drafting and pressurization. The pressure of each rubber roller is the same, and the metal groove roller is driven by a gear box. The whole mechanism is r...
