Detailed Description

The spinning long slot air traction device of the present utility model will be described in more detail below in conjunction with the schematic drawings, in which preferred embodiments of the present utility model are shown, it being understood that one skilled in the art could modify the utility model described herein while still achieving the advantageous effects of the utility model. Accordingly, the following description is to be construed as broadly known to those skilled in the art and not as limiting the utility model.

The utility model is more particularly described by way of example in the following paragraphs with reference to the drawings. Advantages and features of the utility model will become more apparent from the following description and from the claims. It should be noted that the drawings are in a very simplified form and are all to a non-precise scale, merely for convenience and clarity in aiding in the description of embodiments of the utility model.

As shown in fig. 1 and 2, an embodiment of the present utility model provides a spinning long slit air flow drawing device, which comprises a communicating pipe 1, a nozzle 2, a stretching pipe 3 and an interception member 4.

One end of the communicating pipe 1 is communicated with an external high-speed air pipe, so that the air flows into the communicating pipe 1 and applies a traction force to spinning, and the traction force is specifically shown as an arrow in fig. 1.

One end of the nozzle 2 extends into the communicating pipe 1 to guide and suck the spinning.

The drawing tube 3 is placed at the bottom of the communicating tube 1 and forms an annular slit 5 with the nozzle 2, i.e. the spinning is carried out through the annular slit 5 by air flow and into the drawing tube 3.

As shown in fig. 2, in this embodiment, a specific blocking member 4 is provided to remove the fluff and foreign matters adhered to the outside of the spinning, so as to effectively prevent the fluff or foreign matters from causing failure in the subsequent process.

In particular, the interceptor 4 comprises a plurality of support plates 41, a flexible mesh 42 and a slip ring 43.

One end of each supporting plate 41 is hinged to the inner wall of the stretching pipe 3, and two adjacent supporting plates 41 are connected through the flexible net 42, namely an interception net is formed, so that fluff and sundries outside spinning are intercepted.

The slip ring 43 is movably installed between the plurality of support plates 41, and is used for guiding spinning, so that the spinning is penetrated out from the middle part of the slip ring 43 and passes through the opening at the bottom of the interception net until penetrating out of the stretching tube 3.

Wherein, when the slip ring 43 moves in the vertical direction, a plurality of the support plates 41 are driven to expand or contract.

To sum up, in this embodiment, an interception net is formed by arranging the supporting plate 41 and the flexible net 42 to intercept the external fluff and foreign matters of the spinning, and then the slip ring 43 is arranged to guide the spinning, so that when the bottom of the interception net is pulled by the slip ring 43 to be in a contracted state, the foreign matters and fluff outside the spinning are blocked by the interception net, and further the separation of the fluff or foreign matters from the spinning is completed, the normal operation of the subsequent process is ensured, and the purpose of improving the spinning processing efficiency is achieved.

The elastic component 6 is disposed between the outer wall of the supporting plate 41 and the inner wall of the stretching tube 3, so that when the slip ring 43 is in a normal state, the openings formed at the bottom ends of the plurality of supporting plates 41 are contracted, that is, the bottom ports of the interception net are contracted, so as to intercept the foreign matters and the fluff.

It should be noted that the output power of the air flow should be smaller than the elastic force provided by the elastic component 6, so as to ensure that the port at the bottom of the interception net is still in a contracted state during the spinning traction process, so as to intercept fluff and foreign matters.

When the slip ring 43 moves downward along the vertical direction, the openings formed at the bottom ends of the plurality of support plates 41 are expanded, so that the clothes and the nap can be cleaned at this time, and the foreign matters and the nap are prevented from splashing under the influence of the airflow.

In other embodiments, the interceptor member 4 comprises a hinge lever 44; the hinge lever 44 is matched with the support plate 41.

One end of the hinge rod 44 is hinged to the sliding ring 43, and the other end is hinged to the supporting plate 41, that is, the sliding ring 43 slides downwards to pull the plurality of supporting plates 41 to deflect along the direction away from each other so as to complete expansion of the interception net, and when the sliding ring 43 slides upwards, the plurality of supporting plates 41 are pulled to gather along the direction close to each other so as to complete contraction of the interception net.

In order to ensure stability when the slip ring 43 moves, the support plate 41 and the hinge rod 44 are all annularly arranged with the center of the slip ring 43 as the center of the array.

In a further embodiment, a rectifying assembly 7 is provided to make the air flow traction force applied to the spinning relatively uniform.

Specifically, referring to fig. 1, a rectifying component 7 is disposed inside the communicating tube 1.

The rectifying component 7 comprises an annular plate 71 and an air outlet plate 72 which are sequentially arranged from top to bottom; the annular plate 71 is arranged on the inner wall of the communicating pipe 1 and sleeved outside the nozzle 2; the air outlet plate 72 is arranged on the inner wall of the communicating pipe 1 and is fixedly connected with the nozzle 2; a plurality of air outlet holes 721 are provided in the air outlet plate 72.

Further, the plurality of air outlet holes 721 are annularly arranged.

As shown by the position indicated by the arrow in fig. 1, the air flow firstly enters the communicating pipe 1 from the outside, and enters the upper part of the air outlet plate 72 along the surrounding cavity formed between the annular plate 71 and the nozzle 2, and the annular air outlet holes 721 are arranged above the air outlet plate 72, so that the air is split into a plurality of air outlet holes 721 for air outlet, i.e. a plurality of groups of air flows are dispersed outside the spinning in a wrapping manner, so that the spinning can be vertically pulled, the condition that the spinning cannot effectively intercept foreign matters or fluff due to offset in the pulling process is effectively avoided, and the effect of removing the external fluff and the foreign matters of the spinning is further improved.

It will be apparent to those skilled in the art that various modifications and variations can be made to the present utility model without departing from the spirit or scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
