Description

Technical Field

[0001] The present invention relates to the technical field of cable processing, and particularly to a flat composite cable processing device. Background Art

[0002] With the continuous advancement of modernization construction, people's requirements for material life are increasing day by day. The functions of various buildings and facilities are becoming more and more complete, and the equipment and devices are also showing the characteristics of diversification and complexity. As a crucial component in electrical systems and equipment, wire and cable undertakes the key tasks of power transmission and signal transmission, and plays an indispensable role in modernization construction. Therefore, higher requirements are put forward for the functions and performance of wire and cable products.

[0003] Flat composite cable, with its flattened structure and many advantages such as being able to be bent and folded arbitrarily, has been widely used in the fields of data transmission and power transmission of electrical equipment. It can arbitrarily select the number of conductors and the spacing according to actual needs, making the wiring more convenient, thus effectively reducing the product volume, lowering the production cost, and improving the production efficiency.

[0004] In the processing of flat composite cable, the extrusion process is a key link. At present, when the existing processing device extrudes the flat composite cable, it usually completes the extrusion process by pulling the cable core through the extruder. However, during the current traction extrusion process, the distance between the fixed positions at both ends of the cable is very large, and the cable core and the completed cable are very easy to shake or vibrate due to external factors. When the cable core shakes, it will cause the distance between the cable cores to deviate when the protective sleeve adheres to the surface of the cable core, and the protective sleeve has not cooled and solidified, which will also cause displacement between the cable cores.

[0005] Uneven cable core spacing will cause a series of problems. For example, it will affect the electrical performance of the cable, resulting in unstable power transmission and distorted signal transmission; it may also reduce the overall quality and reliability of the cable, increase the probability of failures, and even in some extreme cases, it will become a source of failure and danger, posing a threat to people's personal and property safety.

[0006] Therefore, it is of great practical significance to develop a flat composite cable and its processing device that can effectively solve the shaking problem during extrusion and ensure uniform cable core spacing. Summary of the Invention

[0007] The purpose of the present invention is to provide a flat composite cable processing device to solve the problem in the prior art that during the processing of flat composite cable, the cable cores are prone to shake or vibrate, resulting in uneven arrangement of cable cores in the extrusion process.

An adjusting hole penetrating through the inside and outside is arranged on the upper side of the stabilizing tube at the position corresponding to the upper stabilizing plate. A lead screw is slidably arranged up and down in the adjusting hole. The lower end of the lead screw is connected with the upper side of the upper stabilizing plate.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. When the present invention enables multiple cable cores to enter the insulation layer extrusion head simultaneously through the cooperation of the upper stabilizing plate and the lower stabilizing shaft in the stabilizing tube, it can maintain stability and avoid the problem of uneven arrangement of cable cores due to jitter after entering; 2. By arranging a stabilizing roller at the extrusion end, it can cooperate with the stabilizing tube to stabilize the cable cores and the formed cable at both ends of the insulation layer extrusion head, thereby improving the uniformity of the arrangement of cable cores after the insulation layer solidifies. Compared with the prior art, after the cable is extruded from the insulation layer extrusion head, it is not until the traction device that the cable is fixed. The span is too large and it is easy to generate jitter. The present invention adds a stabilizing roller between the traction device and the insulation layer extrusion head as a support point to improve the stability of the cable after extrusion; 3. In order to avoid that if the extruded cable contacts the stabilizing roller without being cooled, it will cause deformation of the insulation layer, thereby affecting the thickness uniformity of the insulation layer. Therefore, a cooling part is arranged to cool the extruded cable, solidify the insulation layer of the cable, and preliminarily cool down. By arranging an air cooling component and a spray water cooling component, when the cable is extruded, the air cooling component can be used to quickly solidify the outermost side of the insulation layer, avoiding pits on the cable surface caused by the subsequent spray water cooling component, and the spray water cooling component can absorb the heat of the cable with water to complete the solidification of the whole insulation layer.

Detailed implementation mode

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0033] Figures 1 to 12 The following shows an embodiment of the present invention.

[0034] Embodiment 1:

[0035] A flat composite cable processing device includes an extruder body 1. An insulating layer extrusion head 2 is installed at the discharge port of the extruder body 1. The opposite ends of the insulating layer extrusion head 2 are respectively an inlet end 3 and an extrusion end 4. A stabilizing tube 5 is installed on one side of the inlet end 3 of the insulating layer extrusion head 2. An upper stabilizing plate 6 and a lower stabilizing shaft 7 are arranged at intervals up and down in the stabilizing tube 5. A cooling part 8 is installed on one side of the extrusion end 4 of the insulating layer extrusion head 2. A stabilizing roller 9 is installed on the side of the cooling part 8 away from the insulating layer extrusion head 2. A cooling cavity 10 is arranged in the cooling part 8. An inlet 11 communicating with the cooling cavity 10 is arranged at one end of the cooling part 8 facing the extrusion end 4. An outlet 12 communicating with the cooling cavity 10 is arranged at one end of the cooling part 8 facing the stabilizing roller 9. An air-cooling component is arranged at the position of the cooling cavity 10 close to the inlet 11, and a spray water-cooling component is arranged at the position of the cooling cavity 10 close to the outlet 12. In the present invention, when multiple cable cores 72 enter the insulating layer extrusion head 2 simultaneously through the cooperation of the upper stabilizing plate 6 and the lower stabilizing shaft 7 in the stabilizing tube 5, they can be kept stable, avoiding the problem of uneven arrangement of the cable cores 72 due to jitter after entering. By arranging the stabilizing roller 9 at the extrusion end 4, it can cooperate with the stabilizing tube 5 to stabilize the cable cores 72 and the formed cable at both ends of the insulating layer extrusion head 2, thereby improving the uniformity of the arrangement of the cable cores 72 after the insulating layer 73 solidifies. Compared with the past, after the cable is extruded from the insulating layer extrusion head 2, it is not until the traction device that the cable is fixed, and the span is too large, which is very easy to generate jitter. In the present invention, a stabilizing roller 9 is added between the traction device and the insulating layer extrusion head 2 as a support point to improve the stability of the cable after extrusion. In order to avoid the problem that if the extruded cable contacts the stabilizing roller 9 without cooling, it will cause deformation of the insulating layer 73, thereby affecting the thickness uniformity of the insulating layer 73. Therefore, the cooling part 8 is arranged to cool the extruded cable, so that the insulating layer 73 of the cable is solidified and preliminarily cooled. By arranging the air-cooling component and the spray water-cooling component, when the cable is extruded, the outermost side of the insulating layer 73 can be quickly solidified by means of the air-cooling component, avoiding pits on the cable surface caused by the subsequent spray water-cooling component, and the insulating layer 73 can be integrally solidified by absorbing the heat of the cable by means of the spray water-cooling component with water.

[0036] The side of the cooling section 8 is horizontally provided with a through port 13 communicating with the cooling chamber 10 between the inlet 11 and the outlet 12. Both ends of the through port 13 extend to communicate with the inlet 11 and the outlet 12 respectively; a sliding track 14 is provided at the bottom of the cooling section 8. Through the cooperation of the through port 13 and the sliding track 14, during the commissioning process of the cable extrusion process and at the initial stage of cable traction, debugging needs to be carried out at the extrusion end 4 of the insulation layer extrusion head 2 to ensure the smoothness of the subsequent extrusion process. In order to avoid the cooling section 8 affecting such operations, the entire cooling section 8 is moved away from the cable path through the sliding track 14. After the operator has completed the operation and the cable starts to be continuously extruded, the cooling section 8 is moved back to its original position through the sliding track 14, so that the air-cooling component and the spray water-cooling component cool and solidify the cable. The through port 13 being communicated with the inlet 11 and the outlet 12 can ensure that during the movement of the cooling section 8, the cooling section 8 will not touch the cable. Figure 1 , Figure 2 and Figure 3 The support frame under the sliding track 14 is not shown in Figure 1 , Figure 2 and Figure 3 .

[0037] Embodiment 2:

[0038] The air cooling assembly includes an air outlet duct 15, a lower air shield plate 16 and an air return plate 17. The lower air shield plate 16 is horizontally arranged in the cooling chamber 10. The air outlet duct 15 is arranged on the cavity wall of the cooling chamber 10 away from the through-port 13 on the upper side of the lower air shield plate 16. Both ends of the air outlet duct 15 are closed. An air outlet mesh plate 18 is arranged on the side of the air outlet duct 15 facing the through-port 13. The air outlet duct 15 is connected to an external cold air supply device through an air inlet duct 19. A sliding bar hole 20 connected to the upper side of the cooling part 8 is arranged on the upper cavity wall of the cooling chamber 10 near the through-port 13. The return air plate 17 is slidably arranged in the sliding bar hole 20 up and down. A return air cavity 21 is arranged in the return air plate 17. A return air mesh plate 22 connected to the return air cavity 21 is arranged on the side of the return air plate 17 facing the air outlet duct 15. The return air cavity 21 is connected to a return air duct 23 on the upper side of the cooling part 8. When the cooling part 8 needs to be moved, the return air plate 17 is moved upward from the position of the sliding bar hole 20 to avoid affecting the cable from entering and exiting from the through port 13. The specific cooling process of the air cooling component is that when the cable comes out of the extrusion end 4 and enters the air cooling component through the inlet 11, the outlet pipe 15 blows cold air toward the cable through the outlet mesh plate 18. When the cold air passes through the surface of the cable, it takes away the heat on the surface of the cable, so that the surface of the cable is quickly solidified. After the surface of the cable is solidified, it can avoid the uneven pits or small holes on the surface of the unsolidified cable caused by the impact of water flow when the subsequent spray water cooling component is sprayed for cooling. At the same time, the cold air absorbs heat and heats up, and is discharged through the return air plate 17 and the return air pipe 23. In the process of air cooling, the direction of the cold air is coordinated with the lower wind shield plate 16 and the upper cavity wall of the cooling cavity 10, so that the cold air blows as close to the surface of the cable as possible, thereby improving the heat exchange efficiency.

[0039] An electric lifting rod 25 is vertically mounted on the upper side of the cooling unit 8 through a mounting bracket 24, the output shaft of the electric lifting rod 25 is downward, and the lower end of the output shaft is connected to the upper side of the return air plate 17. By providing the electric lifting rod 25, the rise and fall of the return air plate 17 can be controlled by means of the electric lifting rod 25.

[0040] Embodiment 3:

[0041] The spray water cooling component includes an upper water outlet strip 26 and a lower water outlet strip 27. The upper water outlet strip 26 is installed on the upper cavity wall of the cooling cavity 10 along the direction from the outlet 12 to the inlet 11. An upper water outlet cavity 28 is arranged along the length direction inside the upper water outlet strip 26. An upper water outlet 29 communicating with the upper water outlet cavity 28 is arranged along the length direction on the lower side of the upper water outlet strip 26. An outlet block 30 is installed at the position of the upper water outlet 29 of the upper water outlet cavity 28. Water outlet holes 31 penetrating the upper and lower sides are arranged on the outlet block 30. A flow dividing plate 32 is installed at the upper end of the water outlet holes 31. Flow dividing holes 33 penetrating the upper and lower sides are arranged at the position close to the edge of the flow dividing plate 32. A first air inlet hole 34 is arranged on the inner wall of the water outlet holes 31 below the flow dividing holes 33. The first air inlet hole 34 is inclined upward from inside to outside. A second air inlet hole 35 communicating with the first air inlet hole 34 is arranged on the outer wall of the upper water outlet strip 26. A plurality of layers of water outlet nets 36 are installed at the position close to the lower end of the water outlet holes 31. A first water supply pipe 37 is connected above the outlet block 30 of the upper water outlet cavity 28. A first pressure regulating valve 38 is arranged on the first water supply pipe 37; the lower water outlet strip 27 is installed at the position corresponding to the upper water outlet strip 26 on the lower cavity wall of the cooling cavity 10. A lower water outlet cavity 39 is arranged along the length direction inside the lower water outlet strip 27. A second water supply pipe 40 is connected to the lower water outlet cavity 39. A second pressure regulating valve 41 is arranged on the second water supply pipe 40. A plurality of water outlet short pipes 42 communicating with the lower water outlet cavity 39 are arranged on the upper side of the lower water outlet strip 27; a drain pipe 43 is arranged at the bottom of the cavity of the cooling cavity 10. When the cable is air-cooled by the air-cooling component and the surface of the cable is solidified, it will pass through the spray water cooling component for further cooling to cool and solidify the whole cable. Specifically, when the cable passes through the spray water cooling component, the water sprayed from the upper water outlet strip 26 cools the cable from the upper side of the cable, and the water sprayed from the lower water outlet strip 27 cools the cable from the lower side of the cable. When the upper water outlet strip 26 discharges water, the first water supply pipe 37 supplies cooling water to the upper water outlet cavity 28. The water flow flows from top to bottom under the action of water pressure and gravity. When passing through the flow dividing plate 32, it will be divided by the flow dividing plate 32 and can only flow downward through the flow dividing holes 33. After the water flow passes through the flow dividing holes 33, because the flux of the flow dividing holes 33 is smaller than the flux of the water outlet holes 31, the water flow will accelerate when passing through the flow dividing holes 33. When the accelerated water flow passes through the first air inlet hole 34, the air in the first air inlet hole 34 will be sucked into the water outlet holes 31 due to the Bernoulli principle, and the air and the water flow will be mixed in the water outlet holes 31. The mixed water flow and air will hit a plurality of layers of water outlet nets 36 when moving downward. Through the cutting and impact of the water outlet nets 36, the water flow and air can be mixed to form bubble water, and at the same time, the water outlet nets 36 are used to reduce the flow rate of the bubble water, so as to reduce the impact force of the bubble water on the surface of the cable. The water outlet nets 36 are made of stainless steel fine mesh nets. Through the first pressure regulating valve 38, the water pressure and flow rate of the first water supply pipe 37 entering the upper water outlet cavity 28 can be controlled.When the lower water outlet strip 27 discharges water, the second water supply pipe 40 supplies cooling water to the lower water outlet cavity 39. The lower water outlet cavity 39 makes the water spray upward through a number of short water outlet pipes 42, and the sprayed water contacts the lower surface of the cable to absorb the temperature on the lower side of the cable. This can make the cable cooling more uniform. By setting the second pressure regulating valve 41, the water pressure and flow rate of the second water supply pipe 40 entering the lower water outlet cavity 39 can be adjusted, so that the height of the water column sprayed by the short water outlet pipes 42 can be controlled. A suitable water column height can contact the lower side of the cable without causing too much impact force. The water outlet block 30 can be an integral long strip, and one water outlet block 30 is installed at the position of the water outlet, or it can be installed at the position of the water outlet in the way of splicing multiple water outlet blocks 30. There is no need for too good sealing between two adjacent water outlet blocks 30. The water outlet block 30 is installed into the upper water outlet cavity 28 from below the water outlet, and the upper water outlet strip 26 is fixed to the water outlet block 30 from the side by screws.

[0042] Embodiment 4:

The lower stabilizing shaft 7 is horizontally arranged, and a rotating sleeve 44 is rotatably sleeved on the outer wall of the lower stabilizing shaft 7. A through adjusting hole 45 is arranged on the upper side of the stabilizing tube 5 corresponding to the position of the upper stabilizing plate 6. A lead screw 46 is slidably arranged up and down in the adjusting hole 45. The lower end of the lead screw 46 is connected to the upper side of the upper stabilizing plate 6. Upper nuts 47 and lower nuts 48 are respectively threadedly matched and connected to the outer wall of the lead screw 46 on the upper and lower sides of the adjusting hole 45; a stabilizing block 49 is detachably installed on the lower side of the upper stabilizing plate 6, and a number of through grooves 50 with a circular arc cross-section are recessed on the lower side of the stabilizing block 49. After the cable core 72 enters the stabilizing tube 5, it will fit on the upper side of the lower stabilizing shaft 7, and at the same time, the friction between the cable core 72 and the lower stabilizing shaft 7 is reduced by means of the rotating sleeve 44. The lower stabilizing shaft 7 can provide an upward supporting force for the cable core 72, so that the cable core 72 can be aligned with the inlet end 3 of the insulation layer extruding head 2. Through the stabilizing block 49 on the lower side of the upper stabilizing plate 6 and the through grooves 50 on the stabilizing block 49, each cable core 72 can be positioned respectively, so that a designed distance is maintained between each cable core 72. The stabilizing block 49 is customized according to the specific model of the flat composite cable, specifically including parameters such as the size of the through grooves 50 and the distance between adjacent through grooves 50. The stabilizing block 49 is fixed to the lower side of the upper stabilizing plate 6 by screws, which is convenient for replacement. By the cooperation of the upper nut 47 and the lower nut 48, the position of the lead screw 46 is fixed by the upper nut 47 and the lower nut 48 respectively fitting the inner and outer walls of the stabilizing tube 5, so as to fix the distance between the upper stabilizing plate 6 and the upper side of the rotating sleeve 44, so that different models of flat composite cables can be adapted.

[0044] On the upper side of the upper stabilizing plate 6, a buffer column 51 is vertically arranged. At the upper end of the buffer column 51, a buffer hole 52 is provided. The lower end of the lead screw 46 is connected to the bottom of the buffer hole 52 through a spring 53 inside the buffer hole 52. Vertically arranged on the side of the buffer column 51 is an indicating strip hole 54 communicating with the buffer hole 52. On the outer wall of the buffer column 51 at the edge of the indicating strip hole 54, scales are provided. On the side of the lower end of the lead screw 46, a pointer 55 is provided. One end of the pointer 55 away from the lead screw 46 passes through the indicating strip hole 54 and is placed on the side wall of the buffer column 51. With the help of the spring 53, the contact pressure between the through groove 50 and the surface of the cable core 72 can be controlled. By adjusting different compression degrees of the spring 53, different pressures are applied to the cable core 72 by the through groove 50. In this way, it can not only ensure the complete contact between the through groove 50 and the cable core 72, thus avoiding the shaking of the cable core 72 during the conveying process, but also provide a space for the cable to swing upward when the cable core 72 is subjected to some large external forces. With the cooperation of the pointer 55 and the scales, the compression degree of the spring 53 can be displayed, so as to judge the magnitude of the pressure exerted on the cable core 72 by the through groove 50.

[0045] On the side of the lower stabilizing shaft 7 away from the insulation extrusion head 2 of the stabilizing tube 5, a cooling tube 56 is provided. At both ends of the cooling tube 56, an air inlet pipe 57 and an air outlet pipe 58 are respectively provided. At both ends of the cooling tube 56, wind shielding flexible plates 59 are provided, and notches are provided on the wind shielding flexible plates 59. By providing the cooling tube 56, the cable core 72 can be cooled before entering the insulation extrusion head 2. In this way, when the melted insulation layer 73 in the insulation extrusion head 2 contacts the cable core 72, due to the increase in temperature difference, the heat exchange efficiency will be improved. Thus, after the insulation layer 73 contacts the cable core 72, it can absorb heat and solidify faster, so that the insulation layer 73 near and between the cable cores 72 can be solidified as soon as possible, thereby fixing the relative positions of the cable cores 72. Through the wind shielding flexible plates 59, the leakage of cold air in the cooling tube 56 can be avoided, resulting in waste. The wind shielding flexible plates 59 can be cut from silicone sheets, and the notches are adaptively cut according to the size and quantity of the cable cores 72. The wind shielding flexible plates 59 can be fixed to the ends of the stabilizing tube 5 by means of bonding, screws, etc.

[0046] Example 5:

[0047] A collection water tank 60 is provided on the lower side of the stabilizing roller 9. Installation plates 61 are vertically provided on opposite sides of the notch of the collection water tank 60. A first rotating shaft 62 and a second rotating shaft 63 are respectively provided at both ends of the stabilizing roller 9. The first rotating shaft 62 is driven by a motor 64. A number of rubber ridges 65 are axially provided on the surface of the stabilizing roller 9. Sponge 66 is filled between adjacent two rubber ridges 65. A water pipe 67 is axially provided in the sponge 66 along the stabilizing roller 9. A number of water outlet round holes are provided on the side wall of the water pipe 67. A connection hole 68 is recessed at the end of the second rotating shaft 63. The water pipe 67 is communicated with the connection hole 68. A water pump 69 is installed at the bottom of the collection water tank 60. The water outlet end of the water pump 69 is connected with a third water supply pipe 70. The third water supply pipe 70 is rotatably connected with the end of the second rotating shaft 63 through a rotating joint 71. Although the cable is cooled and solidified by the cooling part 8, the temperature of the cable is still very high. Subsequently, it still needs to pass through the cooling water tank for further cooling so that the cable can be reduced to room temperature. When the cable enters the cooling water tank, during the traction process by virtue of its own weight, the part that sags downward will come into contact with the cooling water in the cooling water tank for cooling. With the help of the stabilizing roller 9, the cable and the cable core 72 between the stabilizing pipe 5 and the stabilizing roller 9 can be kept in good levelness and will not sag too much, which can improve the quality of the extruded cable. Since the temperature of the cable is still very high when it contacts the stabilizing roller 9. The reason is that in order to balance the cable and prevent it from sagging due to too large a span, the length of the cooling part 8 is not set too long. Therefore, the cooling effect of the cooling part 8 on the cable is limited. Its purpose is to solidify the cable rather than reduce it to room temperature. In order to prevent the stabilizing roller 9 from scratching the cable during the contact process, the surface of the stabilizing roller 9 uses rubber ridges 65 to contact the cable, which can provide sufficient support force while avoiding scratching the cable. In order to prevent the rubber ridges 65 from continuously heating up during the long-term contact with the high-temperature cable, the sponge 66 and the water pipe 67 are used in cooperation to cool the rubber ridges 65. Specifically, the water pump 69 pumps water into the third water supply pipe 70. The third water supply pipe 70 delivers water into the connection hole 68 of the second rotating shaft 63. The water is distributed to all the water pipes 67 through the connection hole 68. The water flows into the sponge 66 through the water outlet round holes on the water pipe 67, making the sponge 66 absorb water. With the water retention capacity of the sponge 66, the rubber ridges 65 can be continuously cooled. By driving the first rotating shaft 62 to rotate with the help of the motor 64, the stabilizing roller 9 can rotate together with the traction speed of the cable.
