Description

Technical Field

[0001] The invention relates to the technical field of cable processing, in particular to composite cable extrusion processing equipment. Background Art

[0002] Composite cable extrusion molding equipment is mainly used for the production of various cables such as power cables, communication cables, control cables, etc. In the production of power cables, composite cables with good insulation and mechanical protection properties can be manufactured, such as cross-linked polyethylene insulated steel belt armored PVC sheathed power cables; in the field of communication cables, composite optical fiber cables that meet the requirements of high-speed data transmission can be produced, which have a multi-layer protection structure to prevent optical fiber damage and ensure signal transmission quality; composite cable extrusion molding equipment is mainly composed of an extruder, a die head mold, a cooling system and a traction device.

[0003] In the composite cable extrusion molding process, different plastic raw materials are first added to the corresponding extruders. These raw materials are plasticized by the rotation of the screw in the extruder, that is, they are transformed from a solid state to a viscous flow state. Then, the plasticized plastic melt passes through different channels of the die head and is extruded according to the pre-designed structure (such as a multi-layer sheath structure or a structure with a filling layer), forming a composite shape at the die outlet, surrounding the core wire of the cable (such as a copper conductor or optical fiber, etc.). The newly extruded composite part is cooled and solidified by the cooling system, and then pulled forward by the traction device at a stable speed. Finally, the composite cable is rolled up by the winding device to complete the entire extrusion molding process.

[0004] The announcement number is CN 114843045B, and the invention name is: A composite cable and its production equipment. The invention relates to the field of cable processing technology, and discloses a composite cable and its production equipment, including an extruded tube, a limit assembly, a connecting assembly and a cable line, wherein a wire bundle is slidably connected inside the extruded tube, a fixed plate is fixedly installed on the left side of the extruded tube, a bottom plate is fixedly installed on the left side of the fixed plate, a connecting ring is fixedly installed on the left side of the bottom plate, and a sleeve is fixedly installed on the left side of the connecting ring. When the composite cable is extruded, the wire bundle passes through the extruded tube and the sleeve, and the movement of the limit assembly is driven by controlling the connecting assembly. The limit assembly limits the wire bundle and reduces the shaking of the wire bundle, so that the wire bundle is more stable when passing through the extruded tube, and the extruded tube is prevented from shaking all the time when passing through the extruded tube, resulting in uneven wrapping during extrusion molding, so that the production quality of the cable is more stable and the generation rate of defective products is reduced.

[0005] The above existing technologies are still unable to achieve precise control of the plasticizing heating temperature, mold heating temperature and extrusion uniformity that occur in the composite cable extrusion production, and are unable to meet higher product technical requirements and product quality requirements. The products cannot be applied to high-precision and cutting-edge technical scenarios, which ultimately indirectly hinders technological progress.

[0034] in, is the maximum plasticizing rated heating working temperature, and n is the number of times the plasticizing heating temperature is required; If the composite cable extrusion control module 20 determines that the second plasticizing and heating mode is used, the plasticizing and heating working temperature correction coefficient K2 is corrected: K2= .

[0035] Specifically, according to the first plasticizing heating mode or the second plasticizing heating mode determined by the composite cable extrusion control module 20, the plasticizing heating temperature correction coefficient K1 or K2 in the data model correction unit 18 is called.

[0044] Specifically, according to the first or second plasticizing and wrapping method determined by the composite cable extrusion control module 20, on the one hand, it is beneficial to improve the compactness of the plasticized material and improve the quality of the composite cable product; on the other hand, in the orderly wrapping process of the insulating layer, shielding layer and protective layer of the composite cable, since the technical requirements for plasticization of each layer are different, according to the intelligent control of the composite cable extrusion control module 20, the uniformity and wrapping compactness of the insulating layer, shielding layer and protective layer are met to ensure the product quality of the composite cable.

[0045] Specifically, when the first plasticizing and wrapping mode is determined by the composite cable extrusion control module 20, the data model correction unit 18 in the composite cable extrusion control module 20 is corrected according to the plasticizing and wrapping correction coefficient, S1 is: S1=

[0046] Wherein, i is the first heating mode of the mold, the second heating mode of the mold, or the third heating mode of the mold.

[0047] When the second plasticizing and wrapping mode is determined by the composite cable extrusion control module 20, the data model correction unit 18 in the composite cable extrusion control module 20 is corrected according to the plasticizing and wrapping correction coefficient, S2 is: S2= .

[0048] Specifically, according to the first or second plasticizing and wrapping method determined by the composite cable extrusion control module 20, the data model correction unit in the composite cable extrusion control module 20 is corrected according to the plasticizing and wrapping correction coefficient S1 or S2, which is conducive to achieving precise control of the plasticizing method, meeting the uniformity and tightness consistency requirements of the insulation layer, shielding layer and protective layer of the composite cable, and improving the product quality of the composite cable.
