Description

Cavity suitable for yarn coating

Technical Field

The invention relates to the technical field of coating cavities, in particular to a cavity suitable for yarn coating.

Background

Generally, after a metal plating process is performed on the surface of a fabric (e.g., yarn), the durability and added value of the fabric can be effectively improved in addition to expectable functions of increasing the moisture resistance, water repellency, antibacterial property, ultraviolet ray resistance, flame retardancy and the like of the whole fabric. However, when the fabric is subjected to a metal plating process, although the metal plating process may be performed by a chemical immersion, coating, or plating technique, process waste water may be generated, which may cause environmental pollution.

Therefore, in order to solve the above-mentioned environmental pollution problem caused by the metal coating with chemical liquid, the industry has proposed improvement schemes in succession, for example, a vacuum coating machine suitable for cloth and yarn disclosed in chinese patent application No. CN-204898062U, wherein in a vacuum chamber (fig. 3), the yarn to be coated is connected to a roller assembly (fig. 4) for supporting and driving the cloth through a pan head (fig. 5); a steel buckle (figure 6) arranged between the pan head (figure 5) and the roller component (figure 4) is used for pressing the yarn and adjusting the density of the yarn; and a vacuum coating device (figure 7) arranged above the roller component (figure 4) is used for coating the yarns to be coated.

In summary, although the vacuum coating machine suitable for cloth and yarn can greatly improve the environmental pollution doubt caused by the commonly known metal coating process; however, in order to improve the uniformity of the coating thickness of the yarn on-line during the coating process, the yarn to be coated needs to be coated back and forth for multiple coating strokes to achieve the desired set uniformity of the coating thickness; therefore, in addition to taking time, the yarn tends to be loosened or broken during the yarn traverse.

In summary, it is an object of the present invention to improve a vacuum coater for yarn or its components to effectively solve the above-mentioned problems.

Detailed Description

Referring to fig. 1 to 4, a chamber 20 suitable for coating yarn is disclosed according to a first preferred embodiment of the present invention. Each of the components of the chamber 20 is electrically controlled by a microprocessor (not shown) in the chamber 20.

The chamber 20 is a vacuum chamber for a vacuum process. The cavity 20 has a first opening 201 and a second opening 203 opposite to the first opening 201, and the outside is respectively communicated with an accommodating space 21 in the cavity 20 through the two

openings

201 and 203; an external vacuum device (not shown) is connected to the first opening 201 through a pipeline (not shown) and is communicated with the accommodating space 21 of the cavity 20; and an external coating source (not shown) is communicated with the accommodating space 21 corresponding to the chamber 20 through the second opening 203.

Two yarn guiding members 30, a yarn releasing wheel 31, an ice water wheel 33, a yarn winding wheel 35, two tension wheels 37 and a yarn arranging wheel 39 are arranged in the accommodating space 21 of the cavity 20. The ice water wheel 33 is arranged between the yarn releasing wheel 31 and the yarn winding wheel 35; one tension pulley 37 is disposed between the yarn releasing pulley 31 and the ice water pulley 33, the other tension pulley 37 is disposed between the ice water pulley 33 and the yarn winding pulley 35, and both tension pulleys 37 are adjacent to the first opening 201 of the cavity 20. And the yarn arranging wheel 39 is arranged between the other tension wheel 37 and the yarn winding wheel 35. The two yarn guiding members 30 are disposed side by side and in parallel on one side of the ice-water wheel 33 in the longitudinal direction, and both the two yarn guiding members 30 are adjacent to the two tension wheels 37.

It should be noted that the positions of the wheels or components in the accommodating space 21 of the cavity 20 can be adjusted according to actual requirements, and the number of the wheels or components can be increased or decreased according to actual requirements; in addition, each wheel or component is electrically controlled by the microprocessor of the chamber 20 to tension or adjust the tension of an object 10 to be processed (such as yarn), thereby preventing the object from loosening or breaking during the coating process.

The two yarn guiding members 30 are disposed oppositely, and a plurality of guiding portions 301 are disposed at intervals in the longitudinal direction of any one of the yarn guiding members 30, and preferably, a limiting recess is formed on any one of the guiding portions 301 for limiting the object 10 to be processed (e.g., yarn, etc.). Any two of the guiding portions 301 are connected to each other by a tooth section 302, so that the limiting notches are arranged opposite to each other. It should be noted that only one yarn guiding member 30 may be provided.

The second opening 203 of the chamber 20 of the coating source corresponds to the ice water wheel 33 of the roller assembly 30 and is opposite to the positions of the two yarn guides 30. In addition, the coating source is a vacuum coating device used in vacuum process, such as an evaporation (evaporation) device or a sputtering (sputtering) device mainly based on Physical Vapor Deposition (PVD); the coating material used in vacuum coating can be metal, metal oxide or polymer, which is aimed at increasing the selectivity of the coating material to achieve the desired coating effect.

Based on the cavity 20 for coating yarn disclosed in the first preferred embodiment of the present invention, the following effects are achieved:

Referring to fig. 2 to 6, an operator first installs a relevant wheel or component to be coated in the accommodating space of the cavity 20, and sleeves the whole bundle of the object to be processed 10 (such as yarn) in the yarn releasing wheel 31; then, one end of the yarn end is firstly wound on the tension pulley 37 arranged between the yarn releasing pulley 31 and the ice water pulley 33, and then is wound on the ice water pulley 33 and the plurality of guide parts 301 of the two yarn guiding pieces 30 for a plurality of circles; then, another tension wheel 37 and another yarn-finishing wheel 39 are wound around the yarn-winding wheel 35; then, because the coating source is already corresponding to the ice water wheel 33, when the yarn coating process is performed, the plurality of yarn segments covered on the ice water wheel 33 are coated with the coating material through the coating source; preferably, when the yarn releasing wheel 31, the ice water wheel 33, the yarn winding wheel 35 and the two tension wheels 37 are actuated, the remaining yarn segments of the object 10 to be processed can be sequentially guided onto the ice water wheel 33 for the coating process; preferably, if a servo motor is further used to adjust the axial height of the yarn straightening wheel 39 or to perform the process of traversing the flat cable, the smoothness of the yarn straightening by the yarn winding wheel 35 can be improved. Therefore, the technical effect and the purpose of optimizing the yarn coating process are achieved.

And secondly, the device has the effect of preventing the object to be processed from loosening or breaking when the film coating process is carried out. Referring to fig. 5 and 6, after the object 10 to be processed is wound around the plurality of guiding portions 301 of the two yarn guiding members 30 for several turns, the yarn segments can be respectively limited in the plurality of guiding portions 301 which are limiting recesses, and the yarn segments are not loosened or broken during the coating process due to friction with the continuous tooth segments 302 during the unwinding. Preferably, the material of the periphery of the plurality of guiding portions 301 may be plastic or friction-resistant.

Referring to fig. 7, another yarn guiding member 30A suitable for coating yarn according to a second preferred embodiment of the present invention is disclosed, which has a main structure similar to that of the first preferred embodiment, and the difference is that:
