Description

Technical Field

[0001] This invention relates to the field of cable manufacturing technology, specifically to a continuous vulcanization extrusion double-exit production process and equipment for cables. Background Technology

[0002] Existing continuous vulcanization production lines for wires and cables typically process only one wire or cable per line, resulting in low production efficiency. To produce two or more wires and cables simultaneously, multiple production lines are required, significantly increasing equipment costs and requiring substantial factory space. Improving the "one-in, one-out" vulcanization production model to a "one-out, two-out" model—where one vulcanization production line can simultaneously produce two cables—improves equipment utilization, saves energy, and increases production efficiency compared to the "one-in, one-out" model. Since the two cables are produced and transported synchronously on the same production line, during the final winding, each cable needs to be wound onto two separate winding machines. Furthermore, after the insulation layer is extruded from the two conductive cores, they also need to be wound onto two separate winding machines during temporary storage.

[0003] When two cables produced by our company are wound onto a winding machine, in order to ensure that the cable winding tension and density meet the specifications, one cable is directly wound onto the winding machine along the cable conveying direction, while the other cable is guided by a large-diameter guide plate before being wound onto another winding machine. Furthermore, depending on the height and setting position of the winding machine, the guide plate needs to be tilted to ensure that the cable passes smoothly through the guide plate before being wound. Due to limitations in production site area, in order to achieve a rational layout of the production line and minimize floor space, the winding machine must be positioned according to actual production needs. When the winding machine undergoes initial debugging or changes its position later, the tilt direction and angle of the guide plate and the position of the two guide wheels on the side of the guide plate need to be adjusted. Since the guide plate and guide wheels are fixed to the ground by brackets and bolts, adjusting the position requires removing the bolts and re-drilling holes in the ground to install the guide plate and guide wheels, which is a very troublesome process. On the one hand, the guide plate and guide wheels need to be moved; on the other hand, the relative position of the guide plate and guide wheels needs to be repeatedly adjusted. After determining the position, holes need to be drilled in the ground for fixing. If the installation position is deviated, it needs to be removed and reinstalled. This is very inconvenient during the production debugging stage, time-consuming, and wasteful of a lot of time. It is impossible to guarantee the high-precision installation of the tilt direction and angle of the guide plate and the position of the guide wheels, making both initial debugging and later adjustments very inconvenient.

[0004] Therefore, it is necessary to propose a continuous vulcanization extrusion double-exit production process and equipment for cables that has high production efficiency, good winding quality, and facilitates adjustment of the guide plate and guide wheel according to the position of the winding machine. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a continuous vulcanization extrusion double-exit production process and equipment for cables with high production efficiency, good winding quality, and easy adjustment of the guide plate and guide wheel according to the position of the winding machine.

[0006] To solve the above problems, the technical solution adopted by the present invention is as follows:

[0007] A continuous vulcanizing extrusion double-exit production process for cables includes the following steps:

[0008] Step 1, Insulation Extrusion: The insulation layer is extruded onto the conductive wire core using an extruder. The extrusion die on the insulation layer extruder is a double-headed die, which can extrude the insulation layer onto two conductive wire cores simultaneously to form an insulated wire core.

[0009] Step 2, vulcanization: The insulated wire core is passed through the vulcanization pipe, and the insulation layer is vulcanized by high-pressure steam;

[0010] Step 3: Cooling: Cool the vulcanized insulated wire core.

[0011] Step 4: Cable Formation: Twisting multiple insulated wire cores together to form a cable;

[0012] Step 5, Sheath Extrusion: The sheath of the cable is extruded through an extruder. The extrusion die on the sheath extruder is a double-headed die, which can extrude the sheath of two cables at the same time to form a cable.

[0013] Step Six, Vulcanization: Pass the cable through the vulcanization pipe and vulcanize the sheath with high-pressure steam;

[0014] Step 7: Cooling: Cool the vulcanized cable to reduce its temperature.

[0015] Step 8, Guided winding: Two winding machines are used to wind up the two cables respectively. One cable is directly wound up by the first winding machine, and the other cable is wound up by the second winding machine after passing over the rotatable guide plate.

[0016] Before winding, the tilt direction and tilt angle of the guide plate are adjusted according to the arrangement of the second winding machine, and the positions of the two guide wheels on the side of the guide plate are adjusted so that the cable is smoothly conveyed along the guide groove on the guide plate.

[0017] In one embodiment of the present invention, in step eight, the two guide wheels are respectively set at the positions where the cable enters the guide groove and leaves the guide groove. The axis of the guide wheel is set horizontally. By adjusting the position of the guide wheel, the axis of the guide wheel is made perpendicular to the cable conveying direction at the position where the guide wheel is set.

[0018] In one embodiment of the present invention, before performing the insulation extrusion in step one, the monofilaments are first drawn into wires, then annealed, and then multiple monofilaments are twisted together to form a conductive core.

[0019] In one embodiment of the present invention, the conductive core is powdered before the insulation extrusion in step one and before the sheath extrusion in step five to prevent sticking.

[0020] In one embodiment of the present invention, after cooling the insulation layer in step three, the insulated wire core is temporarily wound up and stored by a winding machine. After producing insulated wire cores of different colors according to production needs, the cabling process in step four is then carried out.

[0021] A production equipment based on the above-mentioned continuous vulcanization extrusion double-outlet production process for cables includes an extruder, a vulcanization pipe, a cooling water tank, a cable forming machine, an extruder, a vulcanization pipe, a cooling water tank, a guiding mechanism, and two winding machines arranged in sequence.

[0022] The guiding mechanism includes a support column fixed to the ground and a rotating sleeve rotatably mounted on the top of the support column. A first locking bolt is provided on the side wall of the rotating sleeve. A first mounting plate is horizontally fixed at the top of the rotating sleeve. A first hinge seat is provided on the first mounting plate. The first hinge seat is hinged to a connecting rod. A support plate is fixed at the other end of the connecting rod. A rotating shaft is fixed on the support plate. The rotating shaft is located in the middle of the guide plate. An adjusting rod is hinged between the connecting rod and the first mounting plate.

[0023] In one embodiment of the present invention, a fixed plate is fixedly provided at the bottom of the support column, and a column is provided on the fixed plate that can rotate around the support column and be locked. A horizontal telescopic rod is provided on the top of the column that can rotate horizontally around it. A vertical telescopic rod is vertically fixed above the outer end of the horizontal telescopic rod, and a tray is fixedly connected to the upper end of the vertical telescopic rod. A second mounting plate is provided on the tray that can rotate horizontally. The second mounting plate is provided with guide wheels and two limiting posts.

[0024] In one embodiment of the present invention, the upper surface of the fixed plate is provided with an annular guide groove, the guide groove has an L-shaped cross-section, a guide block is inserted inside, an adjusting plate is fixedly mounted on the top of the guide block, the column is fixedly mounted on the adjusting plate, and locking holes are vertically opened on the adjusting plate and the guide block, and a second locking bolt is provided in the locking hole;

[0025] The top of the tray has a slot, and a locking block is rotatably locked in the slot. The second mounting plate is fixed on the top of the locking block. The bottom of the tray is provided with a fifth locking bolt to lock the locking block in the slot.

[0026] In one embodiment of the present invention, a bearing is provided between the rotating shaft and the guide plate, and a planar thrust ball bearing is provided between the guide plate and the support plate.

[0027] As one embodiment of the present invention, it also includes a wire drawing machine, an annealing furnace, a stranding machine, and two powder passing boxes; a counter is also provided in front of the two winding machines to count the length of the wound cable and display it on a screen; a tracked traction machine is provided between the cooling water tank and the winding machine.

[0028] The beneficial effects of adopting the above technical solution are as follows:

[0029] The continuous vulcanization extrusion dual-exit production process for cables provided by this invention uses a double-head die in the extruder during the extrusion of the insulation layer and sheath, simultaneously extruding two cables. This allows for continuous extrusion, vulcanization, and winding of two cables on a single production line, significantly improving production efficiency. During winding, one cable is directly wound onto a winding machine along the cable conveying direction, while the other cable is guided by a large-diameter guide plate and then wound onto another winding machine. The guide plate is tilted according to the height and position of the winding machines to ensure the cable passes smoothly through the guide plate before winding, achieving the required winding tension and density, resulting in high-quality winding.

[0030] Furthermore, this invention also provides a production equipment based on the aforementioned continuous vulcanization extrusion dual-exit production process for cables. The tilt direction and angle of the guide disc in the guiding mechanism can be adjusted via a rotating sleeve and an adjusting rod. The height and spatial position of the two guide wheels on the side of the guide disc can also be flexibly adjusted via a rotating drum, a horizontal telescopic rod, a vertical telescopic rod, and a rotating locking block. Without changing the fixed position of the guiding mechanism, the guide disc and guide wheel can be flexibly adjusted according to the positions of the winding machine and the tracked traction machine. The entire production equipment layout is flexible, which is beneficial for optimizing the spatial layout of the production equipment, reducing the floor space, and allowing for reasonable adjustments to the equipment layout according to production needs. Moreover, when the number of winding machines is greater than two, when winding cables onto different winding machines via the guiding mechanism, it is not necessary to remove the guiding mechanism from the ground and re-fix it; the tilt direction and angle of the guide disc and the position of the guide wheels in the guiding mechanism can be directly adjusted.

Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the present invention clearer, the invention will be described clearly and completely below in conjunction with specific embodiments.

[0044] like Figure 1The illustrated continuous vulcanization extrusion double-exit production process for cables includes the following steps:

[0045] Step 1, Insulation Extrusion: The insulation layer is extruded from the conductive wire core through the extruder 2. The extrusion die on the insulation layer extruder is a double-head die 4, which can extrude the insulation layer from two conductive wire cores at the same time to form an insulated wire core.

[0046] Step 2, vulcanization: The insulated wire core passes through vulcanization pipe 5 and the insulation layer is vulcanized by high-pressure steam;

[0047] Step 3: Cooling: Cool the vulcanized insulated wire core.

[0048] Step 4: Cable Formation: Twisting multiple insulated wire cores together to form a cable;

[0049] Step 5, Sheath Extrusion: The extruder 2 extrudes the sheath of the cable after cabling. The extrusion die on the sheath extruder is a double-headed die 4, which can extrude the sheath of two cables at the same time to form a cable.

[0050] Step 6, Vulcanization: Pass the cable through vulcanization pipe 5 and vulcanize the sheath with high-pressure steam;

[0051] Step 7: Cooling: Cool the vulcanized cable to reduce its temperature.

[0052] Step 8, Guided winding: The two cables are wound up by two winding machines respectively. One cable is wound up directly by the first winding machine 47, and the other cable is wound up by the second winding machine 48 after passing over the rotatable guide plate 20.

[0053] Before winding, the tilt direction and angle of the guide plate 20 are adjusted according to the arrangement of the second winding machine 48, and the positions of the two guide wheels 44 set on the side of the guide plate 20 are adjusted so that the cable is smoothly conveyed along the annular guide groove 21 on the cylindrical surface of the guide plate 20.

[0054] In this embodiment, the two guide wheels in step eight are respectively positioned at the cable entry and exit points of the guide groove 21. The axis of the guide wheel 44 is horizontally set. By adjusting the position of the guide wheel 44, the axis of the guide wheel 44 is made perpendicular to the cable conveying direction at the position where the guide wheel 44 is set. In actual production, the position where the cable exits from the tracked traction machine 7 is lower than the cable winding position of the winding machine. Therefore, the guide disc 20 needs to be tilted to ensure that the cable is smoothly and stably wound from the tracked traction machine 7 onto the second winding machine 48. The two guide wheels 44 support the cable and prevent it from sagging off the guide groove 21. After adjusting the tilt angle of the guide plate 20 and the position of the guide wheels 44, the cable's tilt angle is less than that of the guide plate 20 during the transmission process, before entering the guide plate 20 (between the tracked traction machine 7 and the guide wheel 44 at the cable entry point of the guide plate 20) and after leaving the guide plate 20 (between the guide wheel 44 at the cable exit point of the guide plate 20 and the second winding machine 48). This allows the cable to be pressed against the guide wheels 44, which also serve as guides.

[0055] Before the insulation extrusion in step one, the wire is first drawn into monofilaments, then annealed, and then multiple monofilaments are twisted together to form a conductive core.

[0056] The conductive core is powdered with talc before the insulation extrusion in step one and before the sheath extrusion in step five to prevent sticking.

[0057] As a further optimization, in actual production, when the same cable is composed of insulated cores of different colors, after cooling the insulation layer in step three, two insulated cores of the same color are temporarily wound up and stored by a winding machine. After producing insulated cores of different colors according to production needs, insulated cores of different colors are selected for cabling in step four, and multiple insulated cores are twisted together.

[0058] In the production process, the cable is pulled and transported by a tracked traction machine 7 positioned between the cooling water tank 6 and the winding machine. The insulation extrusion, vulcanization, cooling, traction, and guided winding processes in the above production process are the same as those for the sheath insulation extrusion, vulcanization, cooling, traction, and guided winding, and all can pass through... Figure 1 The schematic diagram is shown, but because the diameters of the insulation layer and the sheath are different, the models of the double-headed die 4 used in the insulation layer extruder and the sheath extruder are different.

[0059] like Figures 2-10As shown, the present invention also provides a continuous vulcanization extrusion double-exit cable production equipment, which includes an extruder 2, a vulcanization pipe 5, a cooling water tank 6, a cabling machine, an extruder 2, a vulcanization pipe 5, a cooling water tank 6, a guiding mechanism, and two winding machines arranged in sequence. The vulcanization pipe 5 and the cooling water tank 6 before the cabling machine are used to vulcanize and cool the insulation layer, and the vulcanization pipe 5 and the cooling water tank 6 after the cabling machine are used to vulcanize and cool the sheath. When it is necessary to temporarily store the insulated wire core, a guiding mechanism and two winding machines are also set between the cooling water tank 6 and the cabling machine to wind the cable. A tracked traction machine 7 is also set between the cooling water tank 6 and the winding machines to synchronously pull the two cables.

[0060] The guiding mechanism includes a support column 8 fixed to the ground and a rotating sleeve 9 rotatably mounted on the top of the support column 8. A first locking bolt 10 is provided on the side wall of the rotating sleeve 9, which can lock the position of the rotating sleeve 9 relative to the support column 8. By rotating the rotating sleeve 9, the tilt direction of the guide disk 20 can be adjusted. A first mounting plate 11 is horizontally fixed at the top of the rotating sleeve 9. A first hinge seat 12 is provided on the first mounting plate 11. The first hinge seat 12 is hinged to the connecting rod 13. A support plate 17 is fixed at the other end of the connecting rod 13. A rotating shaft 18 is fixed on the support plate 17. The rotating shaft 18 is located in the middle of the guide disk 20. An adjusting rod 16 is hinged between the connecting rod 13 and the first mounting plate 11. Specifically, a second hinge seat 14 is fixed at the upper end of the connecting rod 13, and a third hinge seat 15 is fixed on the first mounting plate 11. The two ends of the adjusting rod 16 are hinged to the second hinge seat 14 and the third hinge seat 15, respectively. The adjusting rod 16 is a telescopic rod, which can be operated electrically or manually. To save costs, the adjusting rod 16 adopts a manual double-threaded sleeve, including two threaded rods and a central sleeve. The two threaded rods have opposite external threads, and the two ends of the central sleeve are screwed to the two threaded rods. By rotating the central sleeve, the length of the adjusting rod 16 can be adjusted, thereby adjusting the tilt angle of the guide plate 20. As a further optimization, the support column 8 can be designed as a telescopic column, thereby allowing adjustment of the height of the guide plate 20.

[0061] In this embodiment, a fixing plate 23 is fixedly provided at the bottom of the support column 8. The fixing plate 23 has multiple through holes and is fixed to the ground with bolts. A column 30 is provided on the fixing plate 23, which can rotate around the support column 8 and be locked. A horizontal telescopic rod is provided on the top of the column 30, which can rotate horizontally around it. A vertical telescopic rod is vertically fixed above the outer end of the horizontal telescopic rod. A tray 39 is fixed to the upper end of the vertical telescopic rod. A second mounting plate 4101 is provided on the tray 39, which can rotate horizontally. A guide wheel 44 is mounted on the second mounting plate 4101 through a bracket 43. Two limiting posts 46 are provided through a support 45 to prevent the cable from detaching from the guide wheel 44. The limiting posts 46 are located on the side of the guide wheel 44 away from the guide plate 20.

[0062] like Figure 5 and Figure 7 As shown, a rotating cylinder 32 is rotatably mounted on the top of the column 30, and a limiting ring 31 is fixed on the column 30 above and below the rotating cylinder 32. The horizontal telescopic rod includes a horizontal sliding sleeve 33 fixedly connected to the rotating cylinder 31 and a horizontal sliding rod 34 inserted into the horizontal sliding sleeve 33. A third locking bolt 35 is provided on the side wall of the horizontal sliding sleeve 33 to lock the position of the horizontal sliding rod 34 relative to the horizontal sliding sleeve 33. The vertical telescopic rod includes a vertical sliding sleeve 36 fixed to the outer end of the horizontal sliding rod 34 and a vertical sliding rod 37 inserted into the vertical sliding sleeve 36. A fourth locking bolt 38 is provided on the side wall of the vertical sliding sleeve 36 to lock the position of the vertical sliding rod 37 relative to the vertical sliding sleeve 36. The tray 39 is fixed to the upper end of the vertical sliding rod 37. The horizontal sliding sleeve 33, the horizontal sliding rod 34, the vertical sliding sleeve 36, and the vertical sliding rod 37 are all square tubes.

[0063] like Figure 4 As shown, the upper surface of the fixed plate 23 is provided with an annular guide groove 25. The guide groove 25 has an L-shaped cross-section and a guide block 26 is fitted inside. An adjusting plate 27 is fixed on the top of the guide block 26. The column 30 is fixed on the adjusting plate 27. The adjusting plate 27 and the guide block 26 are vertically provided with locking holes 28. A second locking bolt 29 is provided in the locking hole 28. The position of the guide block 26 in the guide groove 25 is locked by the second locking bolt 29.

[0064] like Figure 8 and Figure 10 As shown, the tray 39 has a slot 40 on its top, and a locking block 41 is rotatably engaged in the slot 40. The second mounting plate 4101 is fixed to the top of the locking block 41. A fifth locking bolt 42 is provided at the bottom of the tray 39 to lock the locking block 41 in the slot 40.

[0065] As a further optimization, a bearing is provided between the rotating shaft 18 and the guide disk 20, and a planar thrust ball bearing 19 is provided between the guide disk 20 and the support plate 17. The bearings ensure that the guide disk 20 can rotate smoothly and stably around the rotating shaft 18. A limit plate is provided at the top of the rotating shaft 18 to prevent the guide disk 20 from slipping upwards.

[0066] In addition, the production equipment also includes a wire drawing machine, an annealing furnace, a stranding machine, and a powder sifting box located in front of the extruder. The powder sifting box contains talc powder to prevent the wire cores from sticking together. A counter is also set in front of the two winding machines to count the length of the wound cable and display it on a screen.

[0067] like Figure 11 As shown, the double-headed mold 4 is installed on the die head 3 of the extruder 2. It consists of a mold core 49 and a mold sleeve 52. The mold core 49 is provided with two discharge heads 50 and two discharge channels 51 inside the mold core 49.
