Double-side technological cotton suction device of ring spinning frame

Abstract

The invention relates to a double-side technological cotton suction device of a ring spinning frame. The double-side technological cotton suction device comprises a tail cotton suction air box, a tailair pipe, a tail cotton suction fan, a head cotton suction air box, a head air pipe, a head cotton suction fan, a first middle air pipe and a second middle air pipe. The head cotton suction air box is connected with the first middle air pipe by the head air pipe, the tail cotton suction air box is connected with the second middle air pipe by the tail air pipe, the first middle air pipe and the second middle air pipe are connected with each other and are closed, and the head cotton suction fan and the tail cotton suction fan are arranged in the head cotton suction air box and the tail cotton suction air box. The double-side technological cotton suction device has the advantages that one-way technological cotton suction of a long vehicle is transformed into technological cotton suction of two short vehicles, the original long air pipes are changed into the two short air pipes under the condition that the cross sections of the middle air pipes are guaranteed against being changed, the air pipes are shortened, the total quantity of airflow in the air pipes can be reduced, the flow rate can be lowered, negative pressure loss can be reduced, the consistency of the internal negative pressures of the air pipes can be enhanced, the negative pressure balance can be effectively improved, and cotton suction negative pressure requirements of broken ends of yarns can be assuredly met.

Description

technical field [0001] The invention relates to the field of ring spinning frames, in particular to a double-side process cotton suction device of the ring spinning frame. Background technique [0002] At present, the traditional cotton suction device of ring spinning frame is as follows: figure 2 As shown, the cotton suction air box 2 at the rear of the car is connected with the cotton suction air duct 9 in the car through the cotton suction air duct 4 at the rear of the car, and the cotton suction fan 8 at the rear of the car is installed on the cotton suction air box 2 at the rear of the car. The side is installed at the rear of the ring spinning machine, and the distance from the front to the rear of the long ring spinning machine is very long. In order to meet the negative pressure requirements of the whole machine for cotton suction, the total air flow in the air duct is very large, and the cross section of the air duct And limited, so the flow rate is very large. Du...

Problems solved by technology

[0003] In view of this, the object of the present invention is to provide a double-sided process cotton suction device for ring spinning frame, which aims to overcome the traditional cotton suction device for ring spinning frame due to the long air duct length and large negative pressure loss. , The negative pressure at the rear of the car is unbalanced, which affects the effect of cotton suction when the end is broken
