Description

Technical Field

[0001] The utility model relates to the technical field of copper wire processing, and particularly relates to an annular air knife. Background Art

[0002] Copper wire processing is a complex and diverse process involving multiple steps and techniques. During the copper wire processing, impurities such as oil stains and dust will be adsorbed on the surface of the copper wire. Before the copper wire is wound, it is necessary to clean the surface of the copper wire. However, the existing copper wire cleaning devices have an unsatisfactory cleaning effect on the impurities on the copper wire surface, with a poor cleaning effect. Although the method of using compressed air or other gases to blow off impurities such as copper chips and dirt on the copper wire surface has a relatively fast cleaning speed, there may be a problem of incomplete cleaning.

[0003] Based on this, the utility model designs an annular air knife to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an annular air knife.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an annular air knife, comprising a gland, an outer ring, a connecting plate, set screws, connecting bolts and an air inlet pipe. The front of the outer ring is fixedly connected with the gland, the back of the outer ring is fixedly connected with the connecting plate. The gland and the outer ring are fixedly connected by eight set screws, and the connecting plate and the outer ring are fixedly connected by three connecting bolts.

[0006] As a preferred technical solution of the utility model, an annular side wall is provided at the center of the gland, a conical groove is provided at the center of the outer ring, and a tapered groove with a clearance fit is formed between the annular side wall on the gland and the conical groove on the outer ring.

[0007] As a preferred technical solution of the utility model, a high-pressure chamber is provided inside the outer ring outside the conical groove, an annular nozzle is provided at the outlet of the high-pressure chamber, the high-pressure chamber is communicated with two air inlets, and the two air inlets are symmetrically arranged inside both sides of the outer ring.

[0008] As a preferred technical solution of the utility model, air inlet pipes are symmetrically arranged on both sides of the outer ring, an air inlet is provided at one end of the air inlet pipe, and a threaded pipe is provided at the other end.

[0009] As a preferred technical solution of the utility model, the air inlet pipe is connected to the air inlets symmetrically arranged inside both sides of the outer ring through the threaded pipe.

[0010] As a preferred technical solution of the present utility model, a groove is provided at the connection between the connecting plate and the conical groove, and a wire passing hole is provided at the center inside the groove, and the wire passing hole is communicated with the groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. When the present utility model is in use, when compressed air enters the annular air knife through the air inlet pipe, the compressed air is throttled in its internal chamber and enters the annular nozzle at a high speed. At the nozzle, the air flow is further accelerated and ejected along a specific direction, forming a high-speed air flow ring inside the air knife. This air flow ring can produce a strong purging effect at the outlet of the air knife, performing dust removal, water removal, oil removal or drying on the surface of the copper wire. Since the annular air knife can form a 360° all-round air flow coverage, it can ensure uniform treatment of the copper wire surface and has a good cleaning effect;

[0013] 2. The air flow of the annular air knife of the present utility model is balanced, and the air compression ratio can reach a ratio of 40:1, which can save 35%-50% of the compressed air cost. During the use process, it has low noise, small volume, simple installation, convenient maintenance, and is safe and reliable to use. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment

[0023] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 The present utility model provides the following technical solutions: An annular air knife, comprising a gland 1, an outer ring 2, a connecting plate 3, a set screw 4, a connecting bolt 5 and an air inlet pipe 6. The front surface of the outer ring 2 is fixedly connected with the gland 1, the back surface of the outer ring 2 is fixedly connected with the connecting plate 3. The gland 1 and the outer ring 2 are fixedly connected by eight set screws 4, and the connecting plate 3 and the outer ring 2 are fixedly connected by three connecting bolts 5.

[0024] An annular side wall 101 is provided at the center of the gland 1, and a conical groove 204 is provided at the center of the outer ring 2. The annular side wall 101 on the gland 1 and the conical groove 204 on the outer ring 2 form a tapered groove with clearance fit.

[0025] A high-pressure chamber 201 is provided inside the outer ring 2 outside the conical groove 204. An annular nozzle 202 is provided at the outlet of the high-pressure chamber 201. The high-pressure chamber 201 is communicated with two air inlets 203, and the two air inlets 203 are symmetrically provided inside both sides of the outer ring 2.

[0026] Air inlet pipes 6 are symmetrically provided on both sides of the outer ring 2. One end of the air inlet pipe 6 is provided with an air inlet, and the other end is provided with a threaded pipe 601.

[0027] The air inlet pipe 6 is connected to the air inlet 203 provided inside both sides of the outer ring 2 through the threaded pipe 601 in a matching manner.

[0028] Through the above composition structures of the gland 1, the outer ring 2, the connecting plate 3 and the air inlet pipe 6, the sealed connection between the gland 1 and the outer ring 2 forms a closed space for guiding and compressing air flow. The air inlet pipe 6 is provided on the outer wall of the outer ring 2 as the inlet of compressed air. Through the throttling and accelerating effects of the annular nozzle 202, a high-speed and uniform air flow ring is formed.

[0029] Please refer to Figure 2 、 Figure 4 and Figure 5A groove 301 is provided at the connection between the connecting plate 3 and the cone groove 204 , and a wire hole 302 is provided at the center of the groove 301 , and the wire hole 302 is connected to the groove 301 .

[0030] The copper wire can pass through the wire hole 302 provided on the connecting plate 3 to guide and limit the position of the copper wire, so that the copper wire has better stability when being blown by the wind knife.

[0031] The working principle and use process of the utility model are as follows: during specific use, the copper wire is passed through the wire hole 302 opened on the annular air knife, and then the compressed air is introduced into the air inlet 203 through the air inlet pipe 6, and the compressed air enters the high-pressure chamber 201 through the air inlet 203. The airflow entering the high-pressure chamber 201 is throttled and enters the annular nozzle 202 at a high speed, and is ejected along the annular side wall 101 of the annular air knife at an ultra-high speed through the annular nozzle 202. At this time, a strong vacuum area is generated behind it, and the high-speed ejected airflow pulls a large amount of air around the air knife to be ejected to the other side of the air knife, thereby generating a strong 360° sweeping force. This uniform and powerful airflow continuously and stably blows away impurities such as oil, water, dust, etc. on the copper wire through the air ring of the wind knife, thereby achieving all-round treatment of the copper wire.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
