Description

Technical Field

[0001] The invention belongs to the technical field of cable extrusion, and in particular relates to an extruder for electric wires and cables. Background Art

[0002] Extruder, also known as extruder, is a wire and cable equipment mainly used for extruding the core wires of power cords, power cables, coaxial cables, communication cables, transmission cables, BV civil cables, various high-temperature silicone cables, Teflon, coaxial cables, optical fibers and other wires and cables.

[0003] When the extruder uses a mold to cover a layer of cable sheath on the wire and cable, it usually uses a traction device to transport a single cable into the mold to achieve cable coating. However, in order to reduce the complexity of later wiring and make more effective use of space, multiple cables will be coated together in the same sheath layer to form a whole. At the same time, in order to ensure that multiple cables can be arranged neatly before being coated to avoid disorder, multiple cables will be twisted on a specific twisting machine, and then the cable extruder is used to coat the multiple twisted cables with a sheath layer. However, when the traction device is used to pull the multiple twisted cables, the surface of the twisted cable is rougher than that of a single cable, and there are more protrusions on the surface. When the fixed ring in the traction device is used to fix and pull the twisted cable, it is easy to damage the cable surface when the fixing force is large, and when the fixing force is small, the twisted cable is easy to shake inside the fixing ring during the traction process, resulting in unstable cable position. The unstable cable position will cause uneven thickness of the extruded sheath, affecting product quality and reducing the reliability and production effect of cable extrusion.

[0022] Specifically, the fixing plate 1113 and the pulling plate 1212 can be used to continuously pull and transport multiple twisted cables, ensuring that the outer wall of the cable can be continuously covered with a sheath layer, which greatly improves the reliability and production effect of the device when extruding the cable.

[0023] The operating principle of the present invention is now described as follows: In the present invention, when it is necessary to cover multiple twisted cables with the same sheath layer, the staff first pours the plastic particles into the feed hopper 5 to allow the plastic particles to enter the heating shell 2, and then controls the heating shell 2 and the conveying motor 4 to start, so that the heating shell 2 heats the plastic particles to melt the plastic particles, and at the same time uses the conveying motor 4 to drive the screw 3 to rotate, and the screw 3 rotates in the heating shell 2 to plasticize, mix and push the molten plastic, so that the molten plastic particles are conveyed to the internal cavity of the mold 6 through the output pipe 7. At the same time, the staff sequentially passes one end of the multiple twisted cables through the two conveying rings 115, the limit ring 101 and the mold 6, so that one end of the multiple twisted cables is located on one side of the limit plate 124, and then controls the fifth electric telescopic rod 123 to start, with The movable limit plate 124 moves, and the limit plate 124 is used to simply fix the outer walls of the multiple twisted cables. Then, the second electric slide rail 106 is controlled to start, and the number of the multiple twisted cables is covered according to the need, and the corresponding number of first slide plates 107 are driven to start, so that one end of the first electric telescopic rod 109 is located on one side of the corresponding cable. Then, the corresponding first motor 108 is controlled to start, and the first electric telescopic rod 109 is driven to rotate, so that the inclination angle of the first U plate 1010 is the same as the inclination angle of the corresponding cable. Then, the first electric telescopic rod 109 is controlled to start, so that the internal opening of the first U plate 1010 is located on both sides of the outer wall of the corresponding cable. Then, the second electric telescopic rod 1011 is controlled to start, and the side plate 1012 is driven to move, so that the limit wheel 1013 and the limit wheel 1013 are aligned. The outer wall of the corresponding cable is in contact with each other, and the outer wall of the corresponding cable is limited by the limiting wheel 1013. At this time, the multiple twisted cables are located in the central part of the mold 6. Then, the fourth electric slide rail 117 in the conveying ring 115 above the third groove 111 close to one side of the mold 6 is controlled to start, and the corresponding fourth slide plate 118 is driven to move according to the number of the multiple twisted cables, so that one end of the third electric telescopic rod 1110 is located on one side of the corresponding cable. Then, the second motor 119 is controlled to start to drive the third electric telescopic rod 1110 to rotate, so that the inclination angle of the second U plate 1111 is the same as the inclination angle of the corresponding cable. Then, the third electric telescopic rod 1110 is controlled to start to drive the second U plate 1111 to move, so that the inner opening of the second U plate 1111 is located at On both sides of the outer wall of the corresponding cable, the fourth electric telescopic rod 1112 is controlled to start, and the outer wall of the corresponding cable is fixed by the fixing plate 1113. Then, the corresponding fourth electric slide rail 117 is controlled to start, and the fourth slide plate 118 is driven to move, so that the multiple twisted cables are continuously transported to the inside of the mold 6. At the same time, the sixth electric telescopic rod 1211 above the fifth groove 126 on the other side of the mold 6 is started, and the traction plate 1212 is driven to move, and the outer wall of the multiple twisted cables is fixed by the traction plate 1212. Then, the corresponding fifth electric slide rail 127 is controlled to start, and the fifth slide plate 128 is driven to move, and the cables that have passed through the mold 6 are continuously removed. At the same time, the moving speed of the fifth slide plate 128 is the same as the moving speed of the fourth slide plate 118.To ensure that the cable can be stably pulled and transported, after the fifth slide plate 128 and the fourth slide plate 118 move to the end, the traction plate 1212 and the fixing plate 1113 in another group are controlled to start according to the above steps to fix the cable, and then the cable is transported and pulled according to the above steps. At the same time, the fourth slide plate 118 and the fifth slide plate 128 that are initially moved move in the original direction of movement. After the fourth slide plate 118 and the fifth slide plate 128 of another group move to the end, the fourth slide plate 118 and the fifth slide plate 128 that are initially moved continue to transport and pull the cable to ensure that the cable can be stably pulled and transported. The outer wall of the cable is intermittently coated with a sheath layer. When the limiting wheel 1013 is used to continuously limit the position of the multiple twisted cables, the inclination angle of the multiple twisted cables will continue to change as the cables move. At this time, the second electric slide rail 106 and the first motor 108 are controlled to be continuously started, so that the limiting wheel 1013 can always be in contact with the corresponding outer wall of the cable, ensuring that the multiple twisted cables are stably limited, so that the multiple twisted cables are located in the center of the mold 6. When the multiple twisted cables are continuously moved from the mold 6, the solenoid valve 9 is controlled to open, so that the molten plastic particles in the internal cavity of the mold 6 are evenly distributed. The plurality of twisted cables are coated on the outside of the plurality of twisted cables, so that the plurality of twisted cables form a sheath layer. After being removed from the mold 6, the plurality of twisted cables are quickly cooled by the cooling ring 125, so that the sheath layer can be quickly formed, and the sheath layer of the outer sheath of the plurality of twisted cables is coated. When the plurality of twisted cables need to be coated with the same sheath layer, the plurality of twisted cables at both ends of the mold 6 can be limited by the limiting plate 124 and the limiting wheel 1013, so as to ensure that the plurality of twisted cables are located at the center of the mold 6, and the plurality of twisted cables can be continuously moved. The angle and position of the limiting wheel 1013 are constantly adjusted to ensure that the limiting wheel 1013 can always contact the outer wall of the corresponding cable, so that the limiting wheel 1013 can always limit the outer wall of the corresponding cable during the movement of multiple twisted cables, avoiding the unstable position of multiple twisted cables resulting in uneven thickness of the extruded sheath, which affects the product quality. At the same time, the fixed plate 1113 and the traction plate 1212 can be used to continuously traction and convey the multiple twisted cables, ensuring that the outer wall of the cable can be continuously covered with the sheath layer, which greatly improves the reliability and production effect of the device when extruding the cable.
