Conductor surface treatment device and method for cable manufacturing

Abstract

The present invention discloses a conductor surface treatment device for cable manufacturing, which relates to the technical field of cable manufacturing equipment, including: a trigger mechanism and a flamethrower mechanism. By providing a semi-ring structure with an opening in the flamethrower mechanism, it is beneficial to specifically accommodate the conductor part with residual grease after insufficient combustion occurs, so as to avoid the need to intercept the conductor on the production line, so that the conductor has to pass through the flamethrower mechanism again for re-combustion treatment, which affects the quality. In addition, the folding plate in the flamethrower of the flamethrower mechanism can be opened and closed following the pressure of the flame under the action of the pressure spring, which is beneficial to control the length of the flamethrower in the front-to-back direction, and further to the concentration of the flame at the flamethrower. In addition, the flame coverage area can always cover the circumferential surface of the conductor, ensuring the combustion treatment effect on the conductor, and avoiding the insufficient combustion of the oily thin layer on the conductor after the amount of the provided combustion medium is reduced, which affects the cable quality.

Description

Technical Field

[0001] The invention relates to the technical field of cable manufacturing equipment, and in particular to a conductor surface treatment device for cable manufacturing. Background Art

[0002] The metal conductors of the cable include copper, copper-clad steel, copper-clad aluminum, etc. These metal conductors must undergo several processes of stretching and tempering to meet the requirements for cable use.

[0003] Various saponified coolants are used in the drawing or stranding process, so that an anti-oxidation oily layer is formed on the surface of the metal conductor. When the metal conductor is temporarily not in use, it can also play an anti-oxidation role. However, when manufacturing signal transmission cables, this oily layer and water vapor in the air have a great influence on the transmission performance of the cable: if the oily layer remains on the conductor during cable production, the substance will expand rapidly when the conductor passes through the high-temperature mold, causing air saturation on the cable insulation surface and even direct rupture of bubbles, resulting in defects in the cable and breakdown.

[0004] At present, the treatment methods for the oily thin layer are usually electric heating and fire heating. Fire heating is a method of burning the conductor through a medium to remove the residual oily thin layer on the conductor. However, the extent of the fire heating is related to whether the provided combustion medium is sufficient. If the amount of the provided combustion medium is reduced and it is not discovered in time, resulting in the fire heating becoming smaller, there will still be some oily thin layers on the conductor that have not been burned cleanly, affecting the quality of the cable. Summary of the invention

[0005] One of the purposes of the present invention is to solve the problem that the oily thin layer on the conductor is not sufficiently burned after the amount of the combustion medium provided in the prior art is reduced, thus affecting the quality of the cable.

[0006] A second object of the present invention is to provide a conductor surface treatment method for cable manufacturing.

[0007] To achieve one of the above purposes, the present invention adopts the following technical solution: a conductor surface treatment device for cable manufacturing, which includes: a trigger mechanism and a flame spraying mechanism.

[0008] The trigger mechanism has a flow cavity and an ignition unit. The flow cavity is used to receive a combustion medium, which may be a gas such as propane or methane. The ignition unit is arranged on the side wall of the flow cavity. The ignition unit is an ignition system and an ignition needle of the prior art, which will not be described in detail here.

[0009] The flame-throwing mechanism is arranged at the right end of the trigger mechanism. The right end of the flame-throwing mechanism is a semi-ring structure with an opening, and the semi-ring structure is connected front to back. The flame-throwing mechanism comprises: a fire-dividing chamber, a flame-throwing port, a partition, a folding plate, a limit rod, a pressure spring, and a fire-focusing port.

[0010] The fire-spreading cavity is connected to the flow cavity, and the flame-spraying port is connected to the fire-spreading cavity and the semi-ring structure. The partition is arranged at intervals on the flame-spraying port to divide the flame-spraying port into a plurality of independent spaces.

[0011] The folding plate is arranged in the flame-spraying port forming a plurality of independent spaces, the limiting rod is arranged at both sides of the flame-spraying port, the limiting rod is connected to the folding plate, and the pressure spring is connected to the limiting rod.

[0012] The fire focusing port is connected to the fire dividing cavity and the semi-ring structure, and the fire focusing port is located at the upper and lower ends of the opening of the semi-ring structure.

[0013] In the above technical scheme, when the embodiment of the present invention is used, the conductor is inserted into the semi-ring structure of the flamethrower mechanism or the conductor with the grease portion is directly inserted into the semi-ring structure from the opening of the semi-ring structure horizontally, and then the combustion medium is introduced into the flow cavity in the trigger mechanism, so that the combustion medium flows to the right along the flow cavity. At this time, the combustion medium is ignited by the ignition device in the flow cavity, so that the combustion medium burns and turns into fire.

[0014] The burning flame enters the flame separation chamber of the flame spraying mechanism along the flow chamber, and part of the flame in the flame separation chamber enters each flame spraying port along the flame separation chamber, stretching the folding plate in the flame spraying port to the front and rear sides. At this time, the limit rod moves forward and backward to compress the pressure spring and make the flame spraying port larger. The flame passing through the flame spraying port sprays toward the conductor at the semi-ring structure to burn the grease on the surface of the conductor, while the remaining flame enters the outermost flame focusing port along the flame separation chamber, so that the flame focusing port concentrates the remaining flame to spray and burn the conductor at the semi-ring structure.

[0015] When less combustion medium flows into the flow cavity, the flame pressure at the flame outlet becomes smaller. At this time, the folding plate is pushed by the pressure spring on the limit rod side to fold inward, reducing the size of the flame outlet to prevent the flame ejected from the flame outlet from being insufficient to burn the grease on the conductor surface.

[0016] Furthermore, in an embodiment of the present invention, the trigger mechanism also has a flow control plug and a threaded column, the flow control plug is connected to the threaded column, the threaded column has a knob, and the flow control plug is arranged in the accommodating port at the upper left end of the flow chamber.

[0017] Furthermore, in an embodiment of the present invention, an explosion-proof port is provided at the upper right end of the flow cavity, a passive plug is slidably connected in the explosion-proof port, a return spring is provided at the upper end of the passive plug, and a pressure relief port communicating with the outside is provided at the side end of the passive plug.

[0018] Furthermore, in an embodiment of the present invention, the flow control plug is telescopically connected to the threaded column, and magnets that attract each other are provided at the upper and lower joints between the flow control plug and the threaded column.

[0019] Furthermore, in an embodiment of the present invention, a conducting cavity is provided between the pressure relief port and the accommodating port, and the conducting cavity connects the pressure relief port and the accommodating port.

[0020] When an explosion occurs in the flow cavity, the generated pressure pushes the passive plug in the explosion-proof port to slide, opening the pressure relief port, allowing the pressure generated by the explosion to pour out from the pressure relief port for pressure relief. At the same time, the pressure generated by the explosion enters the receiving port along the pressure relief port and pushes the flow control plug, causing the flow control plug to separate from the threaded column, thereby causing the flow control plug to invade the flow cavity, cutting off the connection between the left and right sides of the flow cavity, and preventing the flamethrower of the flamethrower mechanism from emitting a large amount of flame, damaging the conductor, and affecting the quality of the cable.

[0021] Furthermore, in an embodiment of the present invention, the conductor surface treatment device for cable manufacturing also includes a fuel bottle, which is used to load a combustion medium. The fuel bottle is connected to the flow cavity through a feed pipe, and a control valve is provided between the fuel bottle and the feed pipe for controlling the circulation of the combustion medium.

[0022] Furthermore, in an embodiment of the present invention, the conductor surface treatment device for cable manufacturing further comprises a lifting system, wherein the lifting system comprises a lifting rod, wherein the lifting rod is movably connected to the connection block under the trigger mechanism, wherein the connection block is connected to the lifting rod via a rotating handle, wherein the rotating handle is fixedly connected to the connection block, wherein the rotating handle is rotationally connected to the lifting rod, and wherein the rotating handle comprises a nut, wherein the rotating handle is fixed to the lifting rod. The angle of the trigger mechanism and the flame-spraying mechanism can be adjusted by rotating the rotating handle, and the height of the trigger mechanism and the flame-spraying mechanism can be adjusted by the lifting system, which is beneficial for matching the conductors in production.

[0023] Furthermore, in an embodiment of the present invention, the conductor surface treatment device for cable manufacturing further includes a base, the fuel bottle and the lifting system are both mounted on the base, and universal wheels are provided under the base.

[0024] Furthermore, in an embodiment of the present invention, a rotating mechanism is provided in the fire focusing port of the flame spraying mechanism, and the rotating mechanism includes a rotating block and a fixing ring.

[0025] The fixing ring is fixed at the fire-gathering port, the fixing ring is a hollow structure, and an annular slide is provided on the inner side of the fixing ring. An annular slider is provided on the outer surface of the rotating block, and the annular slider on the door lock is connected to the annular slide. The rotating block has a receiving port and an inclined port, the receiving port is located at the bottom of the rotating block, the receiving port is connected to the fire-gathering port, and the inclined port is connected to the upper surface of the rotating block of the receiving port, and the inclined port is inclined to the upper surface of the rotating block.

[0026] When the flame enters the fire focusing port along the fire dividing cavity, the flame in the fire focusing port flows into the receiving port under the rotating block, enters the inclined port through the receiving port, and finally ejects out along the inclined port. The ejected flame drives the rotating block to rotate along the fixed ring, so that the ejected flame forms a spiral flame in the fire focusing port, which is conducive to the full mixing of air and fuel medium (such as natural gas), ensuring the full combustion of natural gas, and effectively reducing the generation of pollutants such as nitrogen oxides. It has a good dual effect of inhibiting the generation of nitrogen oxides and saving energy and reducing emissions, which is beneficial to enhancing the combustion effect of conductor grease and ensuring the production quality of cables.

[0027] The beneficial effects of the present invention are:

[0028] The present invention provides a semi-ring structure with an opening in the flame-throwing mechanism, which is conducive to accommodating the conductor part with residual grease in a targeted manner after insufficient combustion occurs, thereby avoiding the need to intercept the conductor on the production line, so that the conductor needs to pass through the flame-throwing mechanism again for re-combustion treatment, which affects the quality. In addition, the folding plate in the flame-throwing port of the flame-throwing mechanism can be opened and closed according to the pressure of the flame under the action of the pressure spring, which is conducive to controlling the length of the flame-throwing port in the front-to-back direction, and further conducive to the concentration of the flame at the flame-throwing port. In addition, the flame coverage area can always cover the circumferential surface of the conductor, ensuring the combustion treatment effect of the conductor, and avoiding the insufficient combustion of the oily thin layer on the conductor after the amount of the provided combustion medium is reduced, which affects the cable quality.

[0029] To achieve the second of the above objectives, the present invention adopts the following technical solution: a conductor surface treatment method for cable manufacturing, comprising the following steps:

[0030] Insert the conductor into the semi-ring structure of the flame-spraying mechanism or directly insert the conductor with the grease portion into the semi-ring structure from the opening of the semi-ring structure;

[0031] Then, the combustion medium is introduced into the flow cavity in the trigger mechanism, so that the combustion medium flows to the right along the flow cavity. At this time, the combustion medium is ignited by the ignition device in the flow cavity, so that the combustion medium burns and turns into fire;

[0032] The burning flame enters the flame separation chamber of the flame spraying mechanism along the flow chamber, and part of the flame in the flame separation chamber enters each flame spraying port along the flame separation chamber, pushing the folding plate in the flame spraying port to the front and rear sides. At this time, the limit rod moves forward and backward to compress the pressure spring and make the flame spraying port larger;

[0033] The flame passing through the flame-spraying port is sprayed toward the conductor at the semi-ring structure to burn the grease on the conductor surface, while the remaining flame enters the outermost flame-gathering port along the flame-dividing cavity, so that the flame-gathering port concentrates the remaining flame to spray and burn the conductor at the semi-ring structure;

[0034] When less combustion medium flows into the flow cavity, the flame pressure at the flame outlet becomes smaller. At this time, the folding plate is pushed by the pressure spring on the limit rod side to fold inward, reducing the size of the flame outlet to prevent the flame ejected from the flame outlet from being insufficient to burn the grease on the conductor surface.

[0035] Furthermore, in an embodiment of the present invention, when an explosion occurs in the flow cavity, the generated pressure pushes the passive plug in the explosion-proof port to slide, opening the pressure relief port, so that the pressure generated by the explosion pours out from the pressure relief port for pressure relief. At the same time, the pressure generated by the explosion enters the receiving port along the pressure relief port to push the flow control plug, so that the flow control plug is separated from the threaded column, and then the flow control plug invades into the flow cavity, cutting off the connection between the left and right sides of the flow cavity, thereby preventing the flamethrower of the flamethrower mechanism from emitting a large amount of flame and damaging the conductor.

[0061] Embodiment 1:

[0062] A conductor surface treatment device for cable manufacturing, wherein Figure 1 As shown, it includes: a trigger mechanism 10 and a flame-spraying mechanism 20.

[0063] like Figure 2 As shown, the trigger mechanism 10 has a flow chamber 11 and an ignition unit 12.

The ignition unit 12 is an ignition system and an ignition needle of the prior art, which will not be described in detail here.

[0064] like Figure 2 , 3As shown, the flamethrower mechanism 20 is arranged at the right end of the trigger mechanism 10. The right end of the flamethrower mechanism 20 is a semi-ring structure with an opening, and the semi-ring structure is connected from front to back.

At this time, the limit rod 25 moves forward and backward to compress the pressure spring 26 and make the flame spraying port 22 larger. The flame passing through the flame spraying port 22 is sprayed toward the conductor at the semi-ring structure to burn the grease on the surface of the conductor, while the remaining flame enters the outermost flame focusing port 27 along the flame separation chamber 21, so that the flame focusing port 27 concentrates the remaining flame to spray and burn the conductor at the semi-ring structure.

[0070] like Figure 4 , 5 As shown, when less combustion medium is introduced into the flow cavity 11, the flame pressure at the flame outlet 22 decreases. At this time, the folding plate 24 is pushed by the pressure spring 26 on the side of the limit rod 25 to fold inward, thereby reducing the size of the flame outlet 22 and preventing the flame ejected from the flame outlet 22 from being insufficient to burn the grease on the surface of the conductor.

[0071] The present invention provides a semi-ring structure with an opening in the flame-spraying mechanism 20, which is conducive to accommodating the conductor part with residual grease in a targeted manner after insufficient combustion occurs, thereby avoiding the need to intercept the conductor on the production line, so that the conductor needs to pass through the flame-spraying mechanism 20 again for re-combustion treatment, which affects the quality. In addition, the folding plate 24 in the flame-spraying port 22 of the flame-spraying mechanism 20 can be opened and closed following the pressure of the flame under the action of the pressure spring 26, which is conducive to controlling the length of the flame-spraying port 22 in the front-to-back direction, and further conducive to the concentration of the flame at the flame-spraying port 22. In addition, the flame coverage area can always cover the circumferential surface of the conductor, ensuring the combustion treatment effect of the conductor, and avoiding the insufficient combustion of the oily thin layer on the conductor after the amount of the provided combustion medium is reduced, which affects the cable quality.

At the same time, the pressure generated by the explosion enters the receiving port along the pressure relief port 18 and pushes the flow control plug 13, so that the flow control plug 13 is separated from the threaded column 14, and then the flow control plug 13 invades into the flow cavity 11, cutting off the connection between the left and right sides of the flow cavity 11, and preventing the flamethrower 22 of the flamethrower mechanism 20 from emitting a large amount of flame, damaging the conductor, and affecting the quality of the cable.

9. A conductor surface treatment method for cable manufacturing, wherein: The following steps are involved: Insert the conductor into the semi-ring structure of the flame-spraying mechanism or directly insert the conductor with the grease portion into the semi-ring structure from the opening of the semi-ring structure; Then, the combustion medium is introduced into the flow cavity in the trigger mechanism, so that the combustion medium flows to the right along the flow cavity. At this time, the combustion medium is ignited by the ignition device in the flow cavity, so that the combustion medium burns and turns into fire; The burning flame enters the flame separation chamber of the flame spraying mechanism along the flow chamber, and part of the flame in the flame separation chamber enters each flame spraying port along the flame separation chamber, pushing the folding plate in the flame spraying port to the front and rear sides. At this time, the limit rod moves forward and backward to compress the pressure spring and make the flame spraying port larger; The flame passing through the flame-spraying port is sprayed toward the conductor at the semi-ring structure to burn the grease on the conductor surface, while the remaining flame enters the outermost flame-gathering port along the flame-dividing cavity, so that the flame-gathering port concentrates the remaining flame to spray and burn the conductor at the semi-ring structure; When less combustion medium flows into the flow cavity, the flame pressure at the flame outlet becomes smaller. At this time, the folding plate is pushed by the pressure spring on the limit rod side to fold inward, reducing the size of the flame outlet to prevent the flame ejected from the flame outlet from being insufficient to burn the grease on the conductor surface.

10. The conductor surface treatment method for cable manufacturing according to claim 9, wherein: When an explosion occurs in the flow chamber, the generated pressure pushes the passive plug in the explosion-proof port to slide, opening the pressure relief port, allowing the pressure generated by the explosion to pour out from the pressure relief port for pressure relief. At the same time, the pressure generated by the explosion enters the receiving port along the pressure relief port and pushes the flow control plug, causing the flow control plug to separate from the threaded column, thereby causing the flow control plug to invade the flow chamber, cutting off the connection between the left and right sides of the flow chamber, and preventing the flamethrower of the flamethrower mechanism from emitting a large amount of flame and damaging the conductor.
