Abstract
The utility model discloses a drafting device for a spinning frame. The drafting device comprises a first drafting belt roller, a first drafting roller, a belt ring frame, a second drafting belt roller and a second drafting roller. The first drafting belt roller is arranged in front of the belt ring frame, the first drafting roller is arranged below the first drafting belt roller, the second drafting belt roller is arranged behind the belt ring frame, the second drafting roller is arranged below the second drafting belt roller, the second drafting belt roller is sleeved with an upper belt ring, the second drafting roller is sleeved with a lower belt ring, and pressure sticks are arranged in front of the upper belt ring and the lower belt ring. By the adoption of the drafting belt rollers with the larger diameter, meanwhile, the pressure sticks are arranged between the drafting belt rollers, the pressure sticks share part of pressure of the drafting belt rollers, energy consumption can be reduced, meanwhile, required drafting force can be met, bearing losses and belt roller wear-out period can be reduced, the meshing degree of the belt rings is improved, it is ensured that holding of the upper belt ring and the lower belt ring keeps consistent on yarns, and the product quality is improved.
Description
[technical field]
The utility model relates to the technical field of fine spining machine device, particularly the technical field of drafting system for fine spining machine.
[background technology]
Fine spining machine is a link in the middle of the whole flow process of cotton spinning, and its task is that the rove that Speed frames are spun is processed into spun yarn, and in process, the drafting system in fine spining machine must provide enough drafting forces, makes the sliver got more even.And traditional stretching leather roller diameter is less, larger drafting force need to be provided, required energy consumption is higher, and bearing loss is high, and the roller wear-out period is shorter.
Simultaneously, because apron is subject to larger pressure for a long time, easily occur the untight phenomenon of obvolvent, for the uniformity of additional friction force circle of drafting process, produced certain influence, cause apron to crack, the phenomenons such as evenness fault occur.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of fine spining machine drafting system is proposed, by adopting the larger drawing-off roller of diameter, between drawing-off roller, pressure bar is set simultaneously, by pressure bar, share the partial pressure of drawing-off roller, when reducing energy consumption, meet required drafting force, reduced bearing loss and roller wear-out period, the obvolvent degree that has improved apron, has improved product quality.
For achieving the above object, the utility model proposes a kind of fine spining machine drafting system, comprise the first drawing-off roller, the first drawing rollers, cradle, the second drawing-off roller and the second drawing rollers, described the first drawing-off roller is positioned at the place ahead of cradle, the first drawing rollers are positioned at the below of the first drawing-off roller, described the second drawing-off roller is positioned at the rear of cradle, the second drawing rollers are positioned at the below of the second drawing-off roller, on the second drawing-off roller, be arranged with upper leather ring, on the second drawing rollers, be arranged with lower apron, the place ahead of upper leather ring and lower apron is equipped with pressure bar.
As preferably, the diameter of the first drawing-off roller is 30～35mm, and the diameter of the second drawing-off roller is 30～35mm, by increasing the diameter of roller and pressure bar being set, reduces energy consumption, can provide required drafting force simultaneously.
As preferably, the front end of described cradle is provided with the opening passing for upper leather ring and lower apron, and upper leather ring is walked around cradle and is set on the second drawing-off roller, and lower apron is walked around cradle and is set on the second drawing-off roller.
As preferably, the rearward end of described cradle is provided with arc and arc lower plate, and upper arc and arc lower plate adopt nut assembly to regulate distance between the two, guarantee that upper and lower apron is consistent to the gripping of yarn, the obvolvent degree that has improved apron, has improved product quality.
The beneficial effects of the utility model: the utility model is by adopting the larger drawing-off roller of diameter, between drawing-off roller, pressure bar is set simultaneously, by pressure bar, share the partial pressure of drawing-off roller, when reducing energy consumption, meet required drafting force, bearing loss and roller wear-out period have been reduced, improved the obvolvent degree of apron, guaranteed that upper and lower apron is consistent to the gripping of yarn, has improved product quality.
