Description

Technical Field

[0001] The invention belongs to the technical field of cable processing, and in particular relates to a cable threading device for cable processing. Background Art

[0002] Wires and cables are rope-like cables made of several or several groups of conductors twisted together. Each group of conductors is insulated from each other and often twisted around a center. The entire outside is covered with a highly insulating covering. During the cable processing, after the cable is wound, it is usually wrapped with a protective rubber sheath. During the processing, an extruder is usually used to produce and process it in the form of wrapping. In order to improve the performance of the cable after extrusion and cable threading, the cable usually needs to be vulcanized. Common vulcanization methods include cold vulcanization and hot vulcanization.

[0003] In the prior art, the process steps for cold vulcanization of cables are as follows: after the twisted cable is extruded and cabled through an extruder, the extruded cable rubber protective sleeve is cooled after extrusion. After preliminary cooling, the cable rubber protective sleeve is evenly coated with a cold vulcanizing agent on the surface of the formed rubber protective sleeve under appropriate environmental conditions, so that the vulcanizing agent gradually reacts with the rubber molecules in the rubber protective sleeve to form a cross-linked structure, thereby improving the physical properties of the rubber protective sleeve, such as wear resistance and corrosion resistance. In actual application, when the rubber protective sleeve is cooled after extrusion, it is usually cooled by water. At this time, when the cable is being transported, the cooling water remaining on its surface is easy to dilute the vulcanizing agent, making it difficult for the vulcanizing agent to fully react with the rubber molecules, thereby reducing the physical properties of the cable rubber protective sleeve after cold vulcanization.

[0004] Therefore, a cable threading device for cable processing is needed to solve the problem that the cable rubber protective sleeve formed by extrusion threading in the prior art is difficult to fully react when in contact with the vulcanizing agent, thereby reducing the physical properties of the cable rubber protective sleeve after cold vulcanization treatment.

[0051] Embodiment 1:

[0052] See also Figure 1-7 The present invention provides a cable threading device for cable processing, comprising a processing box 1, the interior of the processing box 1 is sequentially arranged into a cable threading area 11, a cooling area 12 and a cold vulcanization area 13 through two partitions, the processing box 1 also includes a cable threading sleeve 2 arranged in the cable threading area 11 and the end of which extends to the inside of the cooling area 12, and a conveying mechanism 3 is arranged at the front end of the cable threading sleeve 2;

[0053] It should be noted that the top of the cable threading sleeve 2 extends out of the top of the cable threading area 11 and is connected to the extrusion tube of the extruder, which is used to provide molten rubber fluid to the inside of the cable threading sleeve 2, so that the cable formed by twisting can be subjected to mobile extrusion and cable threading processing. A winding mechanism for winding the cable is also provided behind the cold vulcanization area 13, which cooperates with the conveying mechanism 3 to convey the twisted cable, and provides power for the cable to pass through the cable threading area 11, the cooling area 12 and the cold vulcanization area 13 in sequence;

[0054] A symmetrically distributed guide wheel 4 is arranged above the interior of the cooling zone 12, a cooling mechanism 5 is arranged between the two guide wheels 4, a vulcanizing sleeve 6 is arranged inside the cold vulcanizing zone 13, a wiping cotton sleeve 7 is arranged at the front end of the vulcanizing sleeve 6, and a vulcanizing mechanism 8 matched with the conveying mechanism 3 is arranged on the periphery of the wiping cotton sleeve 7;

[0055] It should be noted that the top of the vulcanizing sleeve 6 extends out of the top of the cold vulcanizing zone 13 and is connected to the vulcanizing agent supply pipe, which is used to provide vulcanizing agent to the inside of the vulcanizing sleeve 6, so as to evenly coat the surface of the cable rubber protective sleeve passing through the vulcanizing sleeve 6 with the vulcanizing agent, so that the vulcanizing agent and the rubber molecules react fully to form a cold vulcanization treatment of the cable rubber protective sleeve. The wiping cotton sleeve 7 is used to wipe the residual cooling water on the outer surface of the cable rubber protective sleeve. The setting of the vulcanizing mechanism 8 can be used to perform a self-recovery treatment on the wiping cotton sleeve 7 to fully wipe the residual cooling water to avoid dilution of the vulcanizing agent, and can also improve the contact performance between the vulcanizing agent and the cable rubber protective sleeve and the vulcanizing agent, thereby improving the homogeneity of the vulcanizing agent, thereby ensuring the physical properties of the cable rubber protective sleeve after cold vulcanization.

[0056] Further as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth specifically explaining that the conveying mechanism 3 includes two conveying wheels 31 rotatably mounted on the inner wall of the cable threading area 11 and arranged in an upper and lower position, and the outer ends of the two conveying wheels 31 are coaxially fixed with conveying gears 32, and the two conveying gears 32 are meshedly connected, and a reduction motor 33 is arranged in the cable threading area 11 and is coaxially connected with one of the conveying wheels 31;

[0057] It should be noted that the reduction motor 33 adopts a flat gear reduction motor 33, so as to provide smooth power to the conveying wheel 31. Through the synchronous reverse meshing transmission of the two conveying gears 32, the two conveying wheels 31 can stably convey the twisted cables until they are conveyed to the cable threading sleeve 2 for extrusion and cable threading.

[0058] Further as Figure 1-Figure 6 As shown, it is worth specifically explaining that the cooling mechanism 5 includes an air inlet sleeve 51 which is tightly sleeved on the end of the cable threading sleeve 2, an air inlet pipe 52 which is connected to the bottom of the air inlet sleeve 51 is arranged at the outer end of the processing box 1, an annular sleeve 53 which is coaxially distributed with the end of the wiping cotton sleeve 7 is fixed on the outer surface of the partition, a duct 54 is arranged on the top surface of the annular sleeve 53 which is connected to the top surface of the air inlet sleeve 51, an air outlet hole 55 is opened on the inner wall of the annular sleeve 53, four rotating rods 56 which are distributed in a rectangular shape are rotatably connected to the inner wall of the cooling zone 12, a driving member 57 is arranged between the four rotating rods 56, a pressure wheel 58 is rotatably connected to the bottom ends of the two rotating rods 56 on the same side, and a rotating wheel 59 which is installed on the inner wall of the cooling zone 12 is arranged below each pressure wheel 58;

[0059] It should be noted that the air inlet sleeve 51 and the annular sleeve 53 are respectively fixed on the opposite surfaces of the two partitions, and the air inlet pipe 52 is externally connected to the cold air supply pipe, so as to perform a preliminary extrusion air cooling treatment on the cable rubber protective sleeve formed by the cable threading at the end of the cable threading sleeve 2. Subsequently, the cable rubber protective sleeve formed by the cable threading passes through the guiding effect of the front guide wheel 4, and the four rotating rods 56 are driven by the driving member 57 to rotate synchronously in the opposite direction, so that the pressing wheel 58 and the corresponding rotating wheel 59 are fitted up and down, that is, the cable rubber protective sleeve enters the cooling zone 12, and through the cooperation of the pressure wheel 58 and the rotating wheel 59, the cable rubber protective sleeve is immersed in the cooling water surface for water cooling treatment. When the cable rubber protective sleeve reaches another guide wheel 4, through the connecting effect of the duct 54, the cold air is again cooled from the air outlet 55 to the surface of the cable rubber protective sleeve, and the coolant remaining on the surface of the cable rubber protective sleeve is air-dried, so as to realize the initial air cooling, immersed water cooling and air cooling and air drying cooling of the cable rubber protective sleeve.

[0060] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the driving member 57 comprises rotating gears 571 which are coaxially fixed with the top ends of the four rotating rods 56, two rotating gears 571 at the same end are meshed and connected with an adjusting rack rod 572, a connecting rod 573 is fixed on the top of the two adjusting rack rods 572, and a hydraulic cylinder 574 connected with the connecting rod 573 is arranged on the top surface of the processing box 1;

[0061] It should be noted that when the hydraulic cylinder 574 does not drive the connecting rod 573 to move, the connecting rod 573 is at the lowest position of the processing box 1. At this time, the four rotating rods 56 drive the two pressure wheels 58 to be located at the highest position of the cooling zone 12, respectively close to the adjacent guide wheels 4, and form an upper and lower staggered distribution with the guide wheels 4, so as to facilitate the cable rubber protective sleeve formed by extrusion and cable threading to pass through the cooling zone 12, and then the hydraulic cylinder 574 drives the connecting rod 573 to move upward, and drives the two adjusting rack rods 572 to move upward, and through the synchronous reverse meshing transmission action of the adjusting rack rod 572 and the two rotating gears 571, the four rotating rods 56 respectively drive the two pressure wheels 58 to rotate synchronously in the opposite direction, so that the cable rubber protective sleeve formed by extrusion and cable threading is immersed below the liquid level of the coolant in the cooling zone 12, and the cable rubber protective sleeve is positioned by the pressure wheel 58 and the rotating wheel 59, so as to ensure the stability of the cable rubber protective sleeve when passing through the cooling zone 12 for water cooling.

[0062] Further as Figure 2-Figure 7 As shown, it is worth specifically explaining that the vulcanization mechanism 8 includes a coating sleeve 81 rotatably mounted at the center of the inner wall of the vulcanization sleeve 6, a connecting gear 82 is fixed to the end of the coating sleeve 81, a U-shaped rack rod 83 is meshedly connected to one side of the connecting gear 82, a rotating gear ring 84 is arranged on the periphery of the wiping cotton sleeve 7, a sliding rack rod 85 is meshedly connected to the outer side of the rotating gear ring 84, a transmission member 86 is arranged between the sliding rack rod 85 and the U-shaped rack rod 83, a plurality of extrusion rods 87 that can contact the wiping cotton sleeve 7 are arranged inside the rotating gear ring 84, and an elastic member 88 is connected between the extrusion rod 87 and the inner wall of the rotating gear ring 84;

[0063] It should be noted that when the cable rubber protective sleeve is subjected to air cooling and air drying treatment through the annular sleeve 53, the wiping cotton sleeve 7 wipes the surface of the cable rubber protective sleeve, thereby further reducing the possibility of no cooling water remaining on the surface of the cable rubber protective sleeve, thereby avoiding the residual cooling water from diluting the vulcanizing agent;

[0064] Through the drive of the reduction motor 33 and the transmission effect of the transmission member 86, the U-shaped rack rod 83 and the sliding rack rod 85 are synchronously reciprocated up and down, and through the meshing transmission effect of the sliding rack rod 85 and the rotating gear ring 84, the rotating gear ring 84 is reciprocated in the cold vulcanization zone 13, that is, through the elastic extrusion effect of the elastic member 88, the multiple extrusion rods 87 are always reciprocated in a circular manner on the outer surface of the wiping cotton sleeve 7, so that the residual cooling water adsorbed on the surface of the wiping cotton sleeve 7 is reciprocated and extruded, forming a self-recovery of the water absorption performance of the wiping cotton sleeve 7, thereby further reducing the possibility of no cooling water remaining on the surface of the cable rubber protective sleeve;

[0065] When the U-shaped rack rod 83 reciprocates up and down, the coating sleeve 81 reciprocates on the inner wall of the vulcanizing sleeve 6 through the meshing transmission effect with the connecting gear 82, so that the surface of the cable rubber protective sleeve is evenly coated with the vulcanizing agent. At the same time, the coating sleeve 81 reciprocates in the vulcanizing sleeve 6, effectively improving the homogeneity of the vulcanizing agent.

[0066] It should be noted that the reciprocating extrusion of the extrusion rod 87 on the outer surface of the wiping cotton sleeve 7 and the reciprocating rotation of the coating sleeve 81 on the inner wall of the vulcanizing sleeve 6 can shape the surface of the cable rubber protective sleeve, thereby improving the physical properties of the cable rubber protective sleeve to a certain extent.

[0067] Further as Figure 2 and Figure 3 As shown, it is worth to explain in detail that the transmission member 86 includes an incomplete gear 861 rotatably mounted on the inner wall of the end face of the processing box 1, the outer surface of the incomplete gear 861 is meshedly connected with a U-shaped rack frame 862, the sliding rack rod 85 and the U-shaped rack rod 83 are respectively fixed on both sides of the U-shaped rack frame 862, the incomplete gear 861 and one of the conveying wheels 31 are coaxially fixed by a transmission pulley 863, and the outer surfaces of the two transmission pulleys 863 are provided with a transmission belt 864;

[0068] It should be noted that, through the transmission action of the transmission pulley 863 and the transmission belt 864, the incomplete gear 861 rotates synchronously with the conveying wheel 31, and through the meshing transmission action of the incomplete gear 861 and the U-shaped rack frame 862, the U-shaped rack frame 862 moves back and forth up and down, that is, the synchronous up and down reciprocating motion of the U-shaped rack rod 83 and the sliding rack rod 85 is realized.

[0069] Further as Figure 6 and Figure 7 As shown, it is worth to explain in detail that the elastic member 88 includes a fixed cylinder 881 fixed to the outer surface of the rotating ring, the inner wall of the fixed cylinder 881 is slidably connected with a fixed rod 882, the fixed rod 882 is fixed to the outer surface of the extrusion rod 87, and the interior of the fixed cylinder 881 is provided with an extrusion spring 883 fixed to the opposite surfaces of the fixed cylinder 881 and the fixed rod 882;

[0070] It should be noted that the extrusion spring 883 is in a stretched state inside the fixed cylinder 881, so that the extrusion rod 87 is squeezed into the interior of the wiping cotton sleeve 7, thereby ensuring that the extrusion rod 87 always provides sufficient extrusion force on the wiping cotton sleeve 7, accompanied by its reciprocating rotation with the rotating gear ring 84, thereby forming a circumferential direction of the extrusion water treatment of the wiping cotton sleeve 7, forming a self-recovery treatment of the wiping ability of the wiping cotton sleeve 7, and further reducing the possibility of dilution of the vulcanizer by residual cooling water.

[0071] This embodiment has the following working process: when processing the cable, firstly, the twisted cable is conveyed by the conveying wheel 31 until it passes through the cable threading sleeve 2, and then the molten rubber is sent into the cable threading sleeve 2 through the extruder through the extrusion tube, and it passes through the cooling zone 12 and the cold vulcanization zone 13, and then through the adjustment of the driving member 57, the two pressing wheels 58 are synchronously rotated to the top of the rotating wheel 59, that is, the cable passing through the cold vulcanization zone 13 is partially pulled back, that is, the immersed cooling positioning installation treatment of the cable rubber protective sleeve formed by the cable threading is completed, and it is connected through the winding mechanism at the rear end of the cold vulcanization zone 13, and the preliminary positioning and installation treatment of the cable is completed;

[0072] Through the mutual cooperation of the conveying mechanism 3 and the vulcanizing mechanism 8, the cable is conveyed to the cable threading sleeve 2 in the cable threading area 11 for extrusion and cable threading treatment, and then gradually subjected to air cooling, immersion cooling and residual cooling water air drying treatment in the cooling area 12. Subsequently, after wiping the residual cooling water through the wiping sleeve, the cable reaches the vulcanizing sleeve 6 for cold vulcanization treatment. At this time, the extrusion rod 87 and the coating sleeve 81 are synchronously reciprocated with the conveying mechanism 3 to form a self-recovery of the water absorption capacity of the wiping cotton sleeve 7 and a uniform coating of the cable rubber sleeve, thereby effectively avoiding the dilution effect of the vulcanizing agent in the vulcanizing sleeve 6 caused by the residual cooling water, and at the same time effectively improving the homogeneity of the vulcanizing agent in the vulcanizing sleeve 6, thereby greatly improving the physical properties of the cable rubber protective sleeve after cold vulcanization treatment.

[0073] Embodiment 2:

[0074] Based on the first embodiment, according to Figure 2 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that a mobile positioning mechanism 9 is arranged between the cable sleeve 2 and the conveying wheel 31, and the mobile positioning mechanism 9 comprises a mobile frame 91 slidably mounted on the inner wall of both ends of the processing box 1, and the inner wall of the mobile frame 91 is rotatably connected to two positioning wheels 92 distributed up and down, and the outer surface of the connecting rod 573 is rotatably mounted with two symmetrically distributed pushing rods 93, and the other end of the pushing rod 93 is sleeved on the rotating shaft of the upper positioning wheel 92;

[0075] A conical sleeve 10 is fixed to the outer surface of the moving frame 91, and bristles are arranged on the inner wall of the conical sleeve 10;

[0076] It should be noted that when the connecting rod 573 is in the lowest position of the processing box 1, the moving frame 91 is close to the conveying wheel 31 through the pushing action of the pushing rod 93. When the twisted cable is immersed in liquid for positioning and installation, the moving frame 91 is close to the conveying wheel 31, which effectively improves its convenience in conveying and positioning with the conveying wheel 31. At the same time, when the connecting rod 573 moves upward with the hydraulic cylinder 574, the connecting action of the pushing rod 93 drives the moving frame 91 to move away from the conveying wheel 31. When the cable is subsequently conveyed, extruded and threaded, the balance stability of the cable during transportation is effectively improved. The setting of the conical sleeve 10 and the bristles effectively improves the convenience of the cable in conveying and positioning and the cleaning effect on the cable surface.

[0077] In summary, in combination with the two embodiments, it can be known that: through the mutual cooperation of the cooling mechanism 5 and the mobile positioning mechanism 9, the convenience of the cable during the extrusion and cabling process can be effectively improved, and the twisted cable is rotated and transported and extruded and cabled in the cabling area 11 through the conveying mechanism 3, and then preliminary air cooling, immersion cooling and air drying cooling are carried out in the cooling area 12, and finally the residual cooling water is wiped off and the vulcanizing agent is applied in the cold vulcanization area 13, forming an automated process of cable transportation, extrusion and cabling, double cooling and cold vulcanization, which effectively improves the efficiency of the cable cabling process;

[0078] Through the mutual cooperation of the vulcanizing mechanism 8 and the conveying mechanism 3, the extrusion rod 87 and the coating sleeve 81 are made to reciprocate, so that the wiping cotton sleeve 7 can self-restore its water absorption capacity and the vulcanizing agent can be rotated and homogenized, thereby effectively reducing the dilution effect of the residual cooling water on the vulcanizing agent, greatly improving the coating uniformity of the vulcanizing agent and the cable rubber protective sleeve, and effectively ensuring the vulcanization effect of the cold vulcanization treatment.

[0079] The reduction motor 33 and the hydraulic cylinder 574 can both be purchased on the market, and are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.

[0080] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
