Abstract
The invention relates to an integral conduit sheet type relay assistant nozzle for a jet loom, which consists of an integral conduit sheet type relay assistant nozzle, an integral conduit sheet provided with a conical air guide groove, and an air inlet pipe joint. The integral conduit sheet type relay assistant nozzle for the jet loom can change the prior weft insertion means of 'a main nozzle and a conduit sheet type air channel' into the relay weft insertion means of 'a main nozzle, an auxiliary nozzle and a conduit sheet type air channel', so as to meet the demand of weaving wide textile fabrics.
Description
Affiliated technical field
The present invention relates to the integral pipeline segment and the relay assistant nozzle that use on a kind of air-jet loom, belong to the novel fabric manufacture equipment that the weaving thing is knitted by textile mills.
Technical background
Air-jet loom can be divided into two big classes by the difference of its gas channel: pipeline fin-type jet loom and profiled steel reed formula air-jet loom.At present, domestic and international existing pipeline fin-type jet loom all is the filling insertion way that adopt " main burner+conduit sheet type gas channel ", and profiled steel reed formula air-jet loom all is the relay filling insertion way that adopt " main burner+pilot jet+profiled steel reed formula gas channel ".The advantage of the relay filling insertion way of profiled steel reed formula air-jet loom is: the wide cut applicable to fabric is weaved, and shortcoming is: 1. because its gas channel is that " U " shape is semiclosed, and flow leakage is serious, air consumption is big; 2. reed and gas channel are integral type, and be complex-shaped, and the cost height is difficult to adapt to the requirement of frequent replacing kind.The reed of pipeline fin-type jet loom and gas channel are separate type, and cost is low, easily change; But, can not adapt to the woven requirement of fabric wide cut owing to there is not the relay wefting insertion.
Summary of the invention
In order to overcome the defective that existing pipeline fin-type jet loom can not adapt to the woven requirement of fabric wide cut, the invention provides a kind of integral pipeline segment and relay assistant nozzle, so that the filling insertion way of " main burner+conduit sheet type gas channel " of former employing also changes the relay filling insertion way that becomes " main burner+pilot jet+conduit sheet type gas channel ", to satisfy the woven requirement of fabric wide cut.

Fig. 3 is the embodiment installation diagram of integral pipeline segment of the present invention and relay assistant nozzle; Among the figure, 1-main burner 2-integral pipeline segment relay assistant nozzle 3-integral pipeline segment 4-air inlet pipe joint.Link (not drawing among the figure) with alignment pin between each integral pipeline segment relay assistant nozzle and integral pipeline segment, form gas channel jointly.
The specific embodiment
As shown in Figure 3, an integral pipeline segment relay assistant nozzle and gas channel unit of a common composition of integral pipeline segment, its length is L.In each gas channel unit, the center of the spray-hole of integral pipeline segment relay assistant nozzle and the centres of the conical groove on the integral pipeline segment and same angle, the auxilliary gaseous blast that is ejected by the pilot jet spray-hole, conical groove guiding on integral pipeline segment, enter the main jet gas channel of confuser, cross with the main jet air-flow, form one burst relay weft tracting flow.Integral pipeline segment relay assistant nozzle and integral pipeline segment are and use mould once to suppress to form, and the concentricity between each gas channel unit is guaranteed by alignment pin.
The number of gas channel unit is decided according to the fabric width of fabric, and several gas channel unit are arranged closely successively and linked together with alignment pin, are installed in jointly on the slay of loom.Weft yarn enters along the centerline direction of main burner (1), under the effect by the air-flow that radially enters main burner (1), injects gas channel that confuser is formed.Then, each organizes integral pipeline segment relay assistant nozzle (2) sequential action, forms the relay weft tracting flow, and the weft yarn gas channel that flies out under the acting in conjunction of main burner air-flow and relay weft tracting flow is finished the work of air-flow relay wefting insertion.
