The present invention relates to a fiber fabric processing technology, and more particularly, to an improvement of a vacuum suction device for removing foreign matter during fiber fabric processing.

Since foreign matters are generated during the fiber fabric processing, there is a need for a vacuum suction device for removing foreign matters to remove such foreign matters. The vacuum suction device for removing foreign substances used in fabric processing is generally a fixed vacuum suction device.

The fixed vacuum suction device is formed by forming suction holes such as a straight line, a comb-shape, and the like in a transverse direction at a predetermined portion of a fixed bar having a cross-sectional shape such as a circle, a semi-circle, and a square. By passing the fabric over the suction holes, foreign matter attached to the fabric is removed. Such a fixed vacuum suction device has the advantage that it is easy to manufacture because it only needs to provide a function that can be sucked in a specific area.

However, the conventional fixed vacuum suction device as described above has a disadvantage in that its suction effect is lowered because the fabric passes through the lateral suction hole forming portion of the fixed bar in an instant. In addition, the conventional fixed vacuum suction device has a disadvantage in that it is excessively tensioned or damaged on the fabric because it is strongly adhered to the fixed bar by the suction force to pass through the strong friction resistance occurs.

Accordingly, an object of the present invention is to provide a rotary vacuum suction roller which minimizes the possibility of non-uniformity of foreign matter removal and damage due to excessive tension and friction applied to the fabric of the fiber fabric.

It is another object of the present invention to provide a rotary vacuum suction roller which can promote the removal rate of foreign substances in fiber processing.

According to the above object, the present invention, in the vacuum suction device for textile fabric processing, the T-shaped fixed structure 6 for the internal space compartment is fixed in the outer rotary drum (4), which is a rotating body, the outer rotary drum ( The outer surface of the 4) to form the concave-convex curved surface consisting of the bone 8 and the floor 10, the suction holes 12 are formed at regular intervals along the bone 8, the upper plate of the fixed structure (6) ( It is a rotary vacuum suction roller for fabric processing, characterized in that the vacuum suction is made through the suction holes 12 of the outer rotary drum (4) located in the internal available space 16 partitioned by the inner space. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the same elements in the figures are represented by the same numerals wherever possible. In addition, detailed descriptions of well-known functions and configurations that may unnecessarily obscure the subject matter of the present invention will be omitted.

In the embodiment of the present invention to implement a vacuum suction device for removing the foreign material of the fiber fabric, the rotary vacuum suction device should be provided with suction holes that can be sucked at regular intervals on the entire roller surface, structurally suctioned Since the fabric, which is water, contacts only part of the contact surface of the roller surface, the remaining part of the roller surface becomes open from the fabric contact. The inlet suction holes of the roller surface portion induce much more air intake than the air intake into the suction holes of the roller surface portion contacted with the original fabric, so that the foreign material suction power on the fabric surface is significantly lowered.

In an embodiment of the present invention, while the vacuum suction device is implemented in a rotary manner, it eliminates the drawbacks of the suction force deterioration, and also the suction power is spread to the maximum so as to obtain the fabric suction effect evenly, and the advantages of adopting the rotary vacuum suction device are ensured.

The outer rotary drum (4) forms an uneven curved surface consisting of the valleys (8) and the floor (10) on its outer surface, and along the longitudinal direction of the valleys (8) to make up the suction holes 12 at regular intervals. . The outer surface irregularities curved surface of the outer rotary drum (4) has a foreign matter so that the suction force acts to the upper, lower, left, and right periphery of the fiber fabric 50 based on the suction hole 12 of the bone (8) rather than the smooth surface state during vacuum suction In addition to maximizing the suction effect, it also plays a role in minimizing the possibility of non-uniformity in removing foreign material from the fabric.

The outer surface uneven surface structure of the outer rotary drum (4) is an example of a horizontal line in the accompanying drawings, it should be noted that it can be in various forms such as vertical, diagonal, rhombus, lattice. And in the case of embodying the vertical or oblique form, the bone length is formed to rotate along the outer circumference of the cylinder, it is preferable to form the inlet hole 12 located in the bone 8 in the longitudinal direction of the drum.

In addition, in forming the outer surface concave-convex curved structure of the outer rotary drum 4, the pitch between the concave-convex curved floors and the height between the floor and the valleys are set so as to be suitable for the type of main fabric, the type and condition of the foreign matter being sucked. Will be produced.

The space is partitioned into an unavailable space 14. The internal usable space 16 is a partition section provided to enable vacuum suction induction, and the internal unavailable space 14 is a partition space provided to block vacuum suction. In other words, the fixed structure 6 serves to block the inflow of air from the unavailable space 14 as much as possible and maximize the suction efficiency into the internal available space 16 during vacuum suction. That is, the available space 16 is a space provided inside the rotary vacuum suction roller 2 such that the suction force is concentrated only at a predetermined portion in order to minimize the suction force loss and maximize the suction effect.
