Description
Technical Field
[0001] The utility model relates to a sleeve-type side air-blowing thread separator for tubular drafting, which relates to the technical field of nonwoven fabric manufacturing equipment, in particular to a sleeve-type side air-blowing thread separator for tubular drafting. Background Art
[0002] In the spunbond nonwoven fabric production line with tubular drafting, when the filament bundles and the drafting airflow come out of the drafting device, the filament bundles will gather in the center of the drafting tube. In order to improve the uniformity of the product, the gathered filament bundles must be dispersed into evenly distributed single filaments, that is, split filaments, and then formed into a uniform fiber web by swinging the filaments or directly spreading the single filaments evenly on the web-forming machine.
[0003] In order to disperse the gathered filament bundles into single filaments, the commonly used filament separation methods are air flow separation, mechanical separation and electrostatic separation.
[0004] The air flow and electrostatic separation methods have less yarns, but the fiber dispersion effect is limited and cannot be completely dispersed into single fibers. The final product has many "cloud spots", which affects the quality of the product.
[0005] The mechanical fiber separation method has a good fiber dispersion effect and less "cloud spots", but it is easy to produce fiber parallelism, which affects the quality of the product.
[0006] In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a new type of tubular drawing sleeve-type side blowing wire separator to overcome the problems existing in the prior art. Summary of the invention
[0007] According to the technical problem that the existing wire separator proposed in the prior art has poor dispersion effect of the wire bundle and cannot be completely dispersed into single wires, resulting in product quality problems such as parallel wires and "cloud spots", a sleeve-type side-blowing wire separator for tubular drafting is provided. The utility model mainly opens a through hole on the tube wall of the wire separator, and arranges a static pressure cabin with a function of blowing air into the inside of the wire separator outside the through hole to blow the wire bundle, thereby ensuring that the wire bundle is dispersed into single wires, improving the dispersion effect and avoiding the problems of parallel wires and "cloud spots" in the product.
[0008] The technical means adopted by the utility model are as follows:
[0009] A sleeve-type side-blowing wire separator for tubular drawing comprises: a wire separator, a sleeve and an air inlet interface;
[0010] Furthermore, the upper end of the wire separator is connected to the lower part of the drafter, and a plurality of through holes penetrating the inside and the outside are arranged on the tube wall;
[0011] Furthermore, a sleeve is sleeved on the outside of the wire separator, and the upper and lower ends of the sleeve are sealed and connected to the wire separator;

[0015] Furthermore, the air inlet interface is connected to an external air supply device, and the air supply device blows high-pressure gas into the wire separator through the air inlet interface, the static pressure cabin and the through hole to disperse the filament bundle.
[0016] Furthermore, the wire separator comprises: a cylindrical structure, a round-flat gradually deformed structure and a two-stage structure with a round upper part and a flat lower part.
[0017] Furthermore, the connecting port at the upper end and the wire outlet at the lower end of the cylindrical wire separator are both circular structures;
[0018] Furthermore, the diameter of the thread outlet is not less than the diameter of the connection port.
[0019] Furthermore, the connection port at the upper end of the wire separator with a round-flat gradually deformed structure is a round structure, and the wire outlet at the lower end is a flat round opening structure.
[0020] Furthermore, the middle part of the circular-flat gradually deformed structure wire separator is a gradual structure from a circular structure to an oblate-circular structure.
[0021] Furthermore, the shape of the sleeve sleeved outside the wire separator with the round-flat gradually deformed structure is the same as the shape of the wire separator with the round-flat gradually deformed structure.
[0022] Furthermore, the upper round and lower flat two-stage structure wire separator is integrally processed by an upper straight tube part and a lower gradient deformation part;
[0023] Furthermore, the wire divider of the upper straight tube portion is a cylindrical structure with both upper and lower ports being circular structures;
[0024] Further, the diameter of the circular structure of the lower port of the wire divider of the upper straight tube portion is not less than the diameter of the upper port;
[0025] Furthermore, the lower gradually deformed portion gradually changes from a circular structure at the upper end to an oblate circular structure at the lower end of the thread outlet.
[0026] Furthermore, the through hole of the wire separator of the two-stage structure with a round upper part and a flat lower part is opened on the upper straight tube part;
[0027] Furthermore, the sleeve which is mounted on the outside of the wire separator with a two-stage structure of being round on the top and flat on the bottom is mounted on the outside of the upper straight tube part.
[0028] Further, the number of through holes is an even number;
[0029] Furthermore, at least two through holes are symmetrically arranged on the same horizontal plane of the wire separator.
[0030] Furthermore, the through holes are arranged on the cylinder wall of the wire separator in a relatively spaced manner.
[0031] Furthermore, the through holes are arranged on the tube wall of the wire separator in a spiral form.
[0032] Compared with the prior art, the utility model has the following advantages:
[0033] 1. The tubular drawing sleeve-type side-blowing separator provided by the utility model is connected to an external air source, and the external air source directly blows toward the fibers in the separator, so that the fibers are forced to be blown apart in the separator.
[0034] 2. Compared with the existing air flow and electrostatic wire splitters, the sleeve-type side air blowing wire splitter for tubular drawing provided by the utility model adopts forced air blowing, so the fibers are easier to disperse and the "cloud spots" are reduced.
[0035] 3. Compared with the existing mechanical wire splitting, the sleeve-type side-blowing wire splitter for tubular drawing provided by the utility model adopts forced air blowing, so fibers are not prone to double thread.
[0036] In summary, the technical solution of the utility model solves the problem that the existing wire separator in the prior art has poor dispersion effect of the wire bundles and cannot be completely dispersed into single wires, resulting in product quality problems such as wire doubling and "cloud spots" in the product.

[0055] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0056] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0057] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the utility model. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.
[0058] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, numerical expressions and numerical values do not limit the scope of the utility model. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.
[0059] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present utility model: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.
[0060] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" may include both "above" and "below". The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.
[0061] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.
