Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of mining cable processing, and particularly to a mining cable processing and manufacturing device with continuity. Background Art
[0002] The processing of mining cables involves multiple steps, including but not limited to cutting, stripping, joint making, and insulation treatment, etc. Among them, there is a key step of heating and extruding a thermoplastic material (such as cross-linked polyethylene) to form an insulating layer or sheath of the cable. Usually, a copper conductor is continuously fed through the central channel of an extruder and passes through a special component called a "die head". The thermoplastic material is extruded under high temperature and pressure and coated on the copper conductor through the die head to form the required insulating layer or protective sheath. However, during long-term continuous processing operations, especially during peak electricity consumption periods, due to unstable power supply, the extrusion speed is likely to change, resulting in uneven thickness of the insulating layer or sheath in some areas of the entire cable, thereby affecting the quality of the mining cable.
[0003] For example, the processing device for the rubber sheath in the mining cable disclosed in the patent with publication number CN105047328B can carry out continuous processing operations of mining cables, but it cannot adjust in time when the extrusion speed changes, resulting in uneven thickness of the insulating layer or sheath in some areas of the cable, thereby affecting the quality of the mining cable. The wire extrusion speed control system and method disclosed in the patent with publication number CN109616258A can adaptively control the extrusion speed according to the size of the processed cable, but still cannot avoid the problem of uneven thickness of the insulating layer or sheath in some areas of the cable caused by the change in the flow rate of the thermoplastic material due to unstable power supply.
[0004] Therefore, a mining cable processing and manufacturing device with continuity is proposed. Summary of the Invention

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0039] The devices or elements referred to in the embodiments of this application or implied must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of this application. In the description of the embodiments of this application, the meaning of "a plurality" is two or more, unless otherwise specifically and precisely defined.
[0040] Please refer to Figures 1 to 7 , the present invention provides the following technical solutions:
[0041] Example 1: A continuous mining cable processing and manufacturing device, including an extrusion body 1, a housing 11 fixedly connected to the discharge end of the extrusion body 1, a copper wire 12 slidably passing through the housing 11, and a guide wheel 13 slidably abutted against the side wall of the copper wire 12 for guiding the moving direction of the copper wire 12. An extrusion motor 14 is fixedly installed at the driving end of the extrusion body 1 through a motor box. An output shaft 15 is fixedly installed on the output end of the extrusion motor 14 through a coupling. A blade 16 is fixedly installed on the side wall of the output shaft 15. One end of the output shaft 15 is movably installed in the extrusion body 1 through a bearing. One end of the output shaft 15 passes through the extrusion body 1 and the blade 16 is located inside the extrusion body 1. The side wall of the output shaft 15 is fixedly passed through a power gear 2. A detection component for detecting the extrusion process is provided at the extrusion body 1. The detection component includes: a power gear 2, teeth 21, a support plate 201, a movable block 22, a movable ring 23, a sliding block 24, a sliding rod 25, a first spring 26, a guide plate 27, a limiting rod 28, and a control switch 29;
[0042] The power gear 2 is arranged at the driving end of the extrusion body 1, and the inner cavity side wall of the power gear 2 is fixedly installed on the side wall of the output shaft 15. The teeth 21 are meshed with the power gear 2. The side wall of the movable block 22 is fixedly connected to the teeth 21. The inner ring side wall of the movable block 22 is fixedly installed on the side wall of the mounting shaft. Both ends of the mounting shaft are movably installed on the side wall of the support plate 201 through bearings. The bottom of the support plate 201 is fixedly installed on the motor box. The inner ring side wall of the movable ring 23 is movably sleeved on the outer wall of the movable block 22. One end of the sliding block 24 slidably passes through the movable ring 23. One end of the sliding rod 25 slidably passes through the sliding block 24;
[0043] One end of the first spring 26 is fixedly installed in the sliding rod 25, and the other end of the first spring 26 is fixedly installed in the sliding block 24. The first spring 26 provides support for resetting the sliding rod 25. One end of the guide plate 27 is fixed to one end of the sliding rod 25, and the other end of the guide plate 27 slidably abuts against the side wall of the control switch 29. The guide plate 27 changes the opening and closing of the control switch 29 under the action of an external force. One end of the limiting rod 28 is fixedly installed at the bottom of the inner wall of the motor box, and the other end of the limiting rod 28 slidably passes through the guide plate 27. The limiting rod 28 is used to limit the moving direction of the guide plate 27. The side wall of the control switch 29 is fixedly installed on the inner side wall of the motor box. The control switch 29 controls the starting timing of the compensation component under the drive of an external force.
[0044] During use, the thermoplastic material is heated and extruded to form an insulating layer or sheath of the copper wire 12, so that cross-linked polyethylene can be wrapped around the copper wire 12, making the manufactured cable meet the standard of "Coal Mine Cables - Part 13: Cross-linked Polyethylene Insulated Power Cables for Coal Mines with Rated Voltages of 8.7 / 10 kV and Below";
[0045] During the extrusion of thermoplastic materials, the extrusion motor 14 is controlled to start through the console. The output shaft 15 is driven to rotate by the extrusion motor 14, and the output shaft 15 drives the blade 16 to rotate, thereby conveying the melted thermoplastic material to the housing 11 and extruding it from the die head, wrapping it around the copper wire 12 to form an insulating layer or sheath.
[0046] During continuous production, the thermoplastic material is continuously extruded. If the power supply is unstable and the voltage or current fluctuates, the extrusion body 1 will temporarily lose control, resulting in a brief speed fluctuation.
[0047] When there is no speed fluctuation, the output shaft 15 drives the power gear 2 to rotate, the power gear 2 drives the tooth 21 to rotate, the tooth 21 drives the movable block 22 to rotate, the movable block 22 drives the movable ring 23 to rotate. When the movable ring 23 rotates, it applies a force to the sliding block 24, and the sliding block 24 applies a force to the sliding rod 25, enabling the sliding rod 25 to drive the guide plate 27 to move synchronously under the action of centrifugal force. Through the sliding fit between the sliding block 24 and the sliding rod 25, and the sliding fit between the guide plate 27 and the limiting rod 28, when the guide plate 27 moves under the action of centrifugal force, it can only move linearly along the limiting rod 28. The guide plate 27 abuts against the control switch 29, keeping the control switch 29 in the off state.
[0048] When there is a speed fluctuation, since the output shaft 15 loses power, the power gear 2 can no longer drive the tooth 21 to rotate, causing the movable block 22 to be unable to maintain its original rotational speed, reducing the centrifugal force. As a result, the centrifugal force cannot keep the guide plate 27 in its original position, but it moves away from the side where the control switch 29 is located under the action of the first spring 26, causing the guide plate 27 to leave the control switch 29. The control switch 29 automatically resets and turns on, enabling the control switch 29 to control the compensation component to start, thereby assisting the thermoplastic material in the housing 11 to maintain a normal flow rate and preventing the situation where the insulation layer outside the copper wire 12 is thick in some parts and thin in others.
[0049] In another embodiment different from the foregoing embodiment, the movable ring 23 can be cancelled, and the sliding block 24 can be directly slidably placed in the movable block 22.
[0050] Please refer to Figures 8 to 12 、 Figure 14 The present invention provides the following technical solutions:
[0051] The technical solutions of this embodiment different from the foregoing embodiments include: a compensation component for changing the fluidity of the thermoplastic material inside the housing 11 is provided inside the housing 11. The compensation component includes: a compensation motor 3, a rotating shaft 31, an adjusting block 32, a movable shaft 33, an extrusion block 34, an upper slider 35, a lower slider 36, a guide post 37, a second spring 38, an airbag 39, an air pipe 310, an expansion block 311, a sliding plate 312, a third spring 313, and a guide block 314;
[0052] The side wall of the compensation motor 3 is fixedly installed on the top of the housing 11 through a motor base. The compensation motor 3 is used to drive the adjusting block 32 to rotate. One end of the rotating shaft 31 is fixedly installed on the output end of the compensation motor 3 through a coupling. The other end of the rotating shaft 31 slidably penetrates into the housing 11. One end of the rotating shaft 31 located inside the housing 11 is fixedly installed on the top of the adjusting block 32. The rotating shaft 31 is used to conduct the power required for the rotation of the adjusting block 32. The outer wall of the adjusting block 32 is slidably installed inside the housing 11. The adjusting block 32 is used to rotate under an external force to change the fluidity of the thermoplastic material. The top of the movable shaft 33 is fixedly installed at the bottom of the extrusion block 34. The bottom of the movable shaft 33 is movably installed at the bottom of the inner wall of the adjusting block 32 through a bearing. The movable shaft 33 is used to provide support for the extrusion block 34;
[0053] The side wall of the extrusion block 34 is slidably installed inside the adjusting block 32. The horizontal plane of the adjusting block 32 is made of a flexible material. The extrusion block 34 can move under an external force, thereby changing the shape of the adjusting block 32 and cooperating with the adjusting block 32 to change the fluidity of the thermoplastic material. The side wall of the upper slider 35 is fixedly installed on the inner side wall inside the adjusting block 32, and one end of the upper slider 35 is provided with an inclined surface. One end of the lower slider 36 is provided with an inclined surface that is slidably adapted to the inclined surface of the upper slider 35. The two inclined surfaces are slidably abutted against each other. The bottom of the guide post 37 is fixedly installed on the bottom of the inner wall of the adjusting block 32. The other end of the guide post 37 slidably penetrates into the lower slider 36. The guide post 37 is used to limit the moving direction of the lower slider 36. One end of the second spring 38 is fixedly installed at the bottom of the lower slider 36. The second spring 38 is used to provide elastic force for the reset of the lower slider 36. One end of the airbag 39 is fixedly installed on the bottom of the inner wall of the adjusting block 32. The top of the airbag 39 is fixedly installed at the bottom of the lower slider 36. One end of the air pipe 310 is fixedly communicated with the side wall of the airbag 39. The side wall of the expansion block 311 is fixedly communicated with the other end of the air pipe 310;
[0054] The side wall of the sliding plate 312 is in sliding contact with the side wall of the expansion block 311. The bottom of the guide block 314 is fixedly installed at the bottom of the inner wall of the adjusting block 32. The bottom of the sliding plate 312 slides through the guide block 314. The guide block 314 is used to limit the moving direction of the sliding plate 312. One end of the third spring 313 is fixedly installed on the side wall of the sliding plate 312, and the other end of the third spring 313 is fixedly installed in the guide block 314. The third spring 313 is used to provide elastic force for the reset of the sliding plate 312.
[0055] During use, when the control switch 29 is activated, the compensation motor 3 is started. The rotating shaft 31 is driven by the compensation motor 3 to rotate. The rotating shaft 31 drives the adjusting block 32 to rotate, so that the adjusting block 32 rotates from the inside of the housing 11 into the inner cavity, thereby squeezing the thermoplastic material in the inner cavity, enabling the molten thermoplastic material to flow from the inner cavity towards the die head. Thus, when the driving is affected and fluctuates and is lost, the thermoplastic material will not stagnate, which affects the uniformity of the insulating layer wrapped around the copper wire 12.
[0056] Furthermore, when the adjusting block 32 rotates driven by the compensation motor 3, the adjusting block 32 drives the upper slider 35 to rotate synchronously. The upper slider 35 and the lower slider 36 are in sliding contact with each other to squeeze and move the lower slider 36. At the same time, the lower slider 36 and the guide post 37 are in sliding fit. The adjusting block 32 provides a supporting force for the guide post 37, enabling the lower slider 36 to move linearly along the guide post 37 under the squeezing of the upper slider 35. By the downward linear movement of the lower slider 36, the airbag 39 is squeezed and deformed, so that the gas in the airbag 39 is transported into the expansion block 311 through the air pipe 310. After the expansion block 311 expands, it squeezes the sliding plate 312 to move, so that the sliding plate 312 can move away from the side where the expansion block 311 is located under the expansion and extrusion of the expansion block 311. The sliding plate 312 and the guide block 314 are in sliding fit, so that the sliding plate 312 can only move linearly along the guide block 314 under the squeezing of the expansion block 311. By the sliding plate 312 pushing the extrusion block 34, the extrusion block 34 squeezes the deformation surface of the adjusting block 32, so that the deformation surface protrudes from the adjusting block 32, thereby changing the shape of the adjusting block 32, so that the adjusting block 32 can still fit with the arc-shaped space in the inner cavity of the housing 11 after rotation, so that the thermoplastic material in the inner cavity will not penetrate into the arc-shaped space originally occupied by the adjusting block 32 in large quantities, resulting in a situation where although the adjusting block 32 extends from the arc-shaped space into the inner cavity of the housing 11, the extrusion force generated by occupying the inner cavity space is used to compensate for the lack of power for the thermoplastic material to move towards the die head when the driving is lost, but the arc-shaped space has a vacancy to provide extra space for the thermoplastic material to relieve the force, resulting in a poor or useless compensation effect.
[0057] When the driving is restored, the control switch 29 is turned off, thereby controlling the compensation motor 3 to reset to asFigure 14 the initial state shown, and the upper slider 35 is separated from the lower slider 36. The lower slider 36 loses the extrusion force exerted by the upper slider 35 and is reset upward to Figure 10 the initial position shown under the action of the second spring 38. The sliding plate 312 is also reset to the initial position under the action of the third spring 313. At the same time, the airbag 39 is also synchronously reset to the initial position driven by the lower slider 36 and the sliding plate 312, waiting for the next deformation.
[0058] In another embodiment different from the foregoing embodiment, an additional driving method for the compensation motor 3 is added. A temperature sensor is used to monitor the temperature of multiple extrusion sections in the extrusion body 1, and the rotation mode of the compensation motor 3 is adjusted according to the change in the fluidity of the thermoplastic material caused by the temperature change in the multiple extrusion sections. When the temperature is too high and the material fluidity increases, the compensation motor 3 rotates counterclockwise after starting, so that the Figure 14 adjusting block 32 on the right side in rotates counterclockwise and extends out of the arc-shaped space, while the Figure 14 adjusting block 32 on the left side in rotates clockwise and extends out of the arc, increasing the flow resistance of the thermoplastic material. When the temperature is too low and the material fluidity decreases, the compensation motor 3 rotates clockwise, so that the Figure 14 adjusting block 32 on the right side in rotates clockwise and extends out of the arc-shaped space, while the Figure 14 adjusting block 32 on the left side in rotates counterclockwise and extends out of the arc, increasing the flow power of the thermoplastic material.
[0059] In another embodiment different from the foregoing embodiment, the number of compensation motors 3 located in the housing 11 is changed to one, and a gear or other transmission method is used to drive the other rotating shaft 31 to rotate, and it is ensured that the rotation modes of the two rotating shafts 31 are opposite.
[0060] Please refer to Figure 8 、 Figure 13 , the present invention provides the following technical solutions:
[0061] The technical solutions of this embodiment different from the foregoing embodiment include: a compensation component for changing the fluidity of the thermoplastic material in the housing 11 and a flow equalizing component for changing the distribution of the thermoplastic material in the housing 11 are provided in the housing 11. The flow equalizing component includes: a driving motor 4, a driving shaft 41, a driving gear 42, a driven gear 43, a support rod 44, and a spiral strip 45;
[0062] The side wall of the drive motor 4 is fixedly mounted on the side wall of the housing 11 through a mounting seat. The drive motor 4 is used to drive the operation of the flow equalizing component. One end of the drive shaft 41 is fixedly mounted on the output end of the drive motor 4 through a coupling. The other end of the drive shaft 41 movably penetrates into the housing 11. The drive shaft 41 is used to conduct the power of the drive motor 4. The drive gear 42 is located inside the housing 11, and the side wall of the drive gear 42 is fixed to the other end of the drive shaft 41. The driven gear 43 is meshed with the drive gear 42. The bottom of the support rod 44 is fixedly mounted on the side wall of the driven gear 43. One end of the spiral bar 45 is fixedly mounted on the other end of the support rod 44. The spiral bar 45 rotates under the drive of the drive motor 4, thereby disturbing the thermoplastic material in the inner cavity of the housing 11.
[0063] During use, during the process of extruding the thermoplastic material, the drive motor 4 is controlled by the console to drive the drive shaft 41 to rotate. The drive shaft 41 drives the drive gear 42 to rotate. The drive gear 42 drives the driven gear 43 to rotate. The driven gear 43 drives the support rod 44 to rotate. The support rod 44 drives the spiral bar 45 to rotate, so that the spiral bar 45 stirs the thermoplastic material in the inner cavity of the housing 11. Thus, after the thermoplastic material enters the housing 11 from the extrusion body 1, it can be more evenly distributed in a circular shape in the inner cavity of the housing 11, thereby avoiding the situation where the lower half is thick and the upper half is thin when the thermoplastic material is extruded from the die head.
[0064] Furthermore, the rotation speed of the drive motor 4 can be adjusted according to the change in the fluidity of the aforementioned thermoplastic material, so as to adapt to long-term continuous processing.
[0065] In summary, the technical solutions disclosed in the above embodiments of the present invention have at least the following advantages: quickly adjust during short-term fluctuations in the extrusion speed to ensure that the extrusion speed of the thermoplastic material from the die head is not affected.
[0066] Ensure that the thickness of the insulating layer or sheath is uniform, reduce the generation of bubbles, pits or other surface defects, and improve the appearance quality and reliability of the cable.
[0067] Reduce the risk of partial discharge and breakdown, and improve the product quality and production efficiency.
[0068] Reduce costs and equipment maintenance pressure.
