Embodiment Construction
[0043] Attached to the following Figure 1-12 This application will be described in further detail.
[0044] The embodiment of the present application discloses a power cord coating production system. refer to figure 1 , including pay-off equipment 1, lead equipment 2, extrusion equipment 3, water cooling equipment 4, detection equipment 5, wire storage equipment 6 and wire take-up equipment 7 arranged in sequence. Among them, the pay-off device 1 is used to install the core wire and pay off the wire; the lead-out device 2 makes the core wire conveyed from the pay-off device 1 straight and stably input into the extrusion device 3, and the core wire covered with insulating resin After the line comes out of the basic equipment, it directly enters the water cooling equipment 4 for cooling and solidification; the detection equipment 5 is set as a high-frequency electric spark machine, which is used to detect whether the power line has left leakage; the wire storage device 6 is u...

The present application relates to a production system for covering power cords, which includes pay-off equipment, lead wire equipment, extrusion equipment, water cooling equipment, testing equipment, wire storage equipment, and wire take-up equipment arranged in sequence; the extrusion equipment includes a core wire inlet, The core wire outlet, the first injection port, the second injection port, the first injection cavity, the first molding cavity, the second injection cavity and the second molding cavity, the core wire inlet and the core wire outlet are coaxial and connected, and the core A coating cavity is formed between the wire inlet and the core wire outlet, and the core wire passes through the coating cavity straightly. The first injection cavity, the first molding cavity, the second injection cavity, and the second molding cavity are connected in sequence and are located In the cavity, the inner diameter of the second molding cavity is larger than the inner diameter of the first molding cavity; heat preservation mechanisms are provided on the outer peripheral sides of the first molding cavity and the second molding cavity. The application has the advantages of good adhesion of the insulating resin on the surface of the core wire, which can effectively prevent the stress between the core wire and the insulating layer from being peeled off from each other, and ensure the mechanical properties and insulation effect of the power cord.
Description
technical field [0001] The present application relates to the field of wire and cable production, and in particular, to a power cord coating production system. Background technique [0002] The power cord is made of conductors such as aluminum and copper as the core wire wrapped with an insulating plastic layer. In the production process, the core wire of the required specification is made by the wire drawing machine and released from the pay-off frame under the pulling action of the pulling and rotating device. After the equipment is processed, the required cables are formed. [0003] In view of the above-mentioned related technologies, the inventor believes that the adhesion performance of the insulating sheath on the core wire is not good, and stress will be generated between the insulating sheath and the core wire, causing the core wire and the insulating sheath to peel off, affecting the mechanical properties and insulation effect of the power cable. .
