Problems solved by technology

[0004] The existing air suction device of the compact spinning device transformed from the ring spinning frame, such as the air suction device in the compact spinning device of the ring spinning frame disclosed in CN1629372A, uses a blower fan for every 24 spindles, segmental suction, Each fan is driven by a set of transmission mechanism. Although this device can achieve the purpose, it has the defects of complex structure, difficult installation, high modification cost and high power consumption. Will increase yarn hairiness

Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0017] like figure 1 , figure 2 Shown, a kind of air suction device of compact spinning comprises cotton suction duct (not shown in the figure), collecting pipe 2, suction flute pipe 3 and multi-channel connecting pipe 1, the multi-channel connecting pipe 1 One side channel 11 is connected with the cotton suction air pipe, one of the channels 13 on the other side is connected with the cotton suction pipe 3 , and the other two channels 12 are connected with the collecting pipe 2 of the collecting device through the transition pipe 22 .

[0018] The cotton suction air duct is connected with the suction power mechanism in the device such as the suction fan. When the suction device is activated, it not only provides the negative pressure at the collecting pipe, but also sucks away the fine fibers and cotton dust generated at the collecting pipe...

Abstract

An air draft apparatus of tight spin includes a cotton sucking wind pipe, an aggregation tube, a cotton sucking flute pipe and a multichannel connecting pipe, wherein, channels at one side of the multichannel connecting pipe are connected to the cotton sucking wind pipe, one of channels at the other side of the multichannel connecting pipe is connected to the cotton sucking flute pipe, and the other channels are connected to the aggregation tube. The invention possesses the advantages of organically and slickly combining the cotton sucking flute pipe and the cotton sucking wind pipe in the existing ring spinning frame air draft apparatus together with the aggregation tube required by the tight spin; obtaining an air draft apparatus with simple structure; meanwhile being capable of full utilizing the existing air draft apparatus; and having convenient reconstruction, few investment, high economic benefit, high air supply efficiency, low noise and good working atmosphere.

Description

technical field [0001] The invention relates to a compact spinning part, in particular to an air suction device of a compact spinning machine of a ring spinning frame. Background technique [0002] The ring spinning frame is equipped with an air-flow type end-break suction device, which is used to prevent the yarn from floating after the spun end breaks, which will affect the breakage of adjacent spindles or rough knots, and prevent the fibers after end-break from winding on the rollers and rubber rollers. , reduce the content of floating fibers in the workshop air, and improve working conditions. For this reason, the ring spinning frame is generally equipped with an air duct, and the centrifugal fan is used to form a negative pressure in the air duct, and the whiskers output from the front jaw of the roller after the end is broken are sucked into the cotton suction flute, and then gathered to the storage through the air duct. cotton box. [0003] The compact spinning mach...
