Abstract
The utility model discloses a compact spinning negative pressure pipe which comprises a special-shaped tube body [2] provided with two through holes with different sizes and an air suction pipe [3] connected with the pipe body [2], wherein two dovetail slots [1] are arranged on the outer surface of the pipe body [2], the air suction pipe [3] is provided with two dovetail-shaped convex areas [4], the air suction pipe [3] realizes connection with the pipe body [2] through match between the two dovetail-shaped convex areas [4] and the two dovetail slots [1], an air suction pipe locating device is further arranged on the pipe body [2], the air suction pipe locating device comprises a short shaft [5] arranged on the front end of the air suction pipe [3] and a radial through hole located on the pipe body [2], and after the air suction pipe [3] is connected with the pipe body [2], the short shaft [5] is located in the through hole to realize locating. The compact spinning negative pressure pipe can be conveniently disassembled, and can be opened for cleaning and then can be used continuously when the pipe is plugged, thereby lowering the cost.
Description
Technical field
The utility model relates to a kind of compact spinning negative pressure tube, especially a kind of compact spinning negative pressure tube that is connected with body by dovetail groove and swallow-tail form projection realization aspiration channel.
Background technology
The negative pressure pipe is a kind of special pipe of inner chamber hollow, have a plurality of air-flow bothriums on the tube wall of negative pressure pipe one side, a plurality of grid ring are enclosed within respectively on each air-flow bothrium, opposite side then is the negative pressure inlet scoop, negative pressure source is twisted with the fingers certainly when effect makes Yarn filoplume by grid ring by the negative pressure inlet scoop and on each air-flow bothrium filoplume is wrapped on the yarn, thereby reduce the yam surface filoplume significantly, make yam surface clear smooth, increased the intensity of yarn.Owing to connect by negative pressure sucking air pipe between negative pressure pipe and the negative pressure source; negative pressure sucking air pipe generally is to be fixedly connected on the body of negative pressure pipe by welding or glue; negative pressure sucking air pipe causes refuse yarn, shutdown even changes the negative pressure pipe, increased user's cost because have step surface to cause waste cotton to get lodged in negative pressure sucking air pipe easily with negative pressure pipe body junction.
The utility model content
The purpose of this utility model solves existing compact spinning negative pressure tube exactly because of aspiration channel and negative pressure pipe body cause waste spinning, shutdown or replacing negative pressure pipe because of there is step surface the junction, makes the problem that use cost is high.
The technical solution adopted in the utility model is: compact spinning negative pressure tube, it comprises the special-shaped body and the aspiration channel that is connected with body of hollow, the described body that it is characterized in that be provided with two with the consistent dovetail groove of body bar shaped direction, aspiration channel and body link be provided with two with two swallow-tail form projectioies that dovetail groove is suitable, aspiration channel is by two swallow-tail form projectioies and the cooperation realization of two dovetail grooves and being connected of body, also be provided with the aspiration channel positioner on the body, described aspiration channel positioner comprises that minor axis that is located at the aspiration channel front end and the radial direction through hole that is positioned on the body, aspiration channel are connected the back minor axis and are positioned at through hole realization location with body.
Adopt technique scheme, because aspiration channel is by two swallow-tail form projectioies and the cooperation realization of two dovetail grooves and being connected of body, the inner no step surface of negative pressure pipe body, waste cotton wadding by the inspiration of air-flow bothrium can not overstock obstruction negative pressure pipe inlet scoop, and when air draught has damage as the negative pressure pipe, can easily dismantle, need not to change the negative pressure pipe, reduce use cost.
In sum, the beneficial effects of the utility model are: because aspiration channel of the present utility model is by two swallow-tail form projectioies and the cooperation realization of two dovetail grooves and being connected of body, for flexibly connecting, therefore can easily dismantle, when running into obstruction, continue again to use after can opening removing, therefore reduced cost.
