Description
Technical Field
[0001] The utility model belongs to the technical field of wire processing, in particular to a preheating device for wire production. Background Art
[0002] In modern wire and cable production, conductor preheating is a critical step. This process primarily aims to improve the quality and efficiency of insulation coating. The quality of the insulation coating directly impacts the electrical performance and service life of the conductor. Therefore, preheating the conductor using a preheating device during the coating process is crucial to ensuring conductor quality.
[0003] In the conventional preheating device of the prior art, due to the lack of effective guidance during the preheating process, the conductor moves at an uneven speed, which makes it easy for the conductor to be heated unevenly. In addition, the preheating device is mostly fixed and difficult to adjust, which easily leads to uneven surface temperature distribution of the conductor after heating, thereby affecting the coating quality of the insulation layer and the overall performance of the conductor. Utility Model Content
[0004] The purpose of the present invention is to provide a preheating device for wire production to solve at least one aspect of the problems and defects raised in the above background technology.
[0005] A preheating device for wire production is provided, comprising a mounting frame, wire assemblies are provided on both sides of the upper part of the mounting frame, a preheating box is provided between the two wire assemblies, preheating assemblies are provided on the upper and lower sides of the preheating box, and a guide assembly is provided on the inner wall of the preheating box.
[0006] Furthermore, the wire assembly includes a guide wheel frame body, and the upper and lower sides of the guide wheel frame body are connected to wire wheels through a rotating shaft. The two wire wheels are rotatably connected to the guide wheel frame body. The two wire wheels are rotatably connected to the guide wheel frame body. The circular surface of the wire wheel can smoothly guide the movement of the wire, reduce the friction between the wire and the wire wheel, and prevent the wire from being scratched or damaged during movement. The wire wheel can change the height of the wire wheel by adjusting the installation position of the rotating shaft on the guide wheel frame, thereby adapting to wires of different diameters, ensuring that the wire always moves in the center position of the wire wheel, avoiding tilting or twisting and ensuring safety.
[0007] Furthermore, the preheating box is provided with wire retaining holes on both sides. These retaining holes ensure that the wires remain correctly positioned as they pass through the preheating box. The wires do not deviate from the center, thus ensuring uniform preheating. The retaining holes are used to guide the wires along a predetermined path through the preheating box.
[0008] Furthermore, the preheating assembly includes a support frame, which is fixedly connected to the inner wall of the preheating box. Several heating components are arranged on the upper part of the support frame along the length direction. The several heating components can adjust the height from the conveying wire inside the preheating box to adapt to the heating requirements of the middle and sides of the preheating box, ensuring that the surface temperature of the wire is uniform during the preheating process, thereby facilitating the subsequent insulation layer coating work.
[0009] Furthermore, the heating assembly includes a mounting plate, the upper portion of the mounting plate is provided with a mounting groove, the upper portion of the mounting groove is slidably connected to a preheating mounting seat, a heating cylinder is provided on the preheating mounting seat, the heating cylinders are connected to a preheating air duct, and fastening bolts for fixing the preheating mounting seat are provided in the mounting groove. When the preheating mounting seat slides to a suitable position in the mounting groove, the position of the preheating mounting seat is fixed with the fastening bolts to ensure that the heating assembly remains stable during the heating process, and by adjusting the height of each heating cylinder from the conveying wire inside the preheating box, it adapts to the heating requirements of the middle and sides of the preheating box, ensuring that the surface temperature of the wire is uniform during the preheating process, which is beneficial to the subsequent insulation layer coating work.
[0010] Furthermore, the preheating air duct is provided with a regulating valve, the preheating air duct is used to guide the hot air to flow to the preheating area, and the regulating valve is installed on the air duct to control the air flow through the air duct.
[0011] Furthermore, a plurality of air guide holes are provided on the upper portion of the heating cylinder along the circumferential direction. The air guide holes enable the hot air generated by the heating cylinder to flow evenly to the heated object, avoiding local overheating or insufficient heating, thereby achieving a more uniform heating effect.
[0012] Furthermore, a door is hinged on the preheating box body, which is convenient for operators to open the door and install the preheating components in the preheating box body when production starts.
[0013] Furthermore, the guide assembly includes several guide rollers, which are rotatably connected to the inside of the preheating box. The guide rollers are used to guide the wires to be heated to move more evenly in the preheating box, ensuring that the wires are evenly heated during the preheating process of the preheating box.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] The preheating component can adjust its height position from various areas of the wire in the preheating box in real time to ensure that the temperature of various areas of the wire is maintained uniformly during the preheating process, thereby ensuring the stability of the wire quality, and preheating the wire passing through the preheating box. Another wire component then transfers the heated wire to the next process for coating, which facilitates the quality of subsequent insulation coating. Through the coordinated work of the wire component, preheating box, preheating component and guide component, the wire can be moved smoothly and continuously and preheated uniformly during the production process. The wire can be effectively guided during the preheating process, with uniform movement speed and uniform heating. The preheating device can adjust the distance from the wire to be heated, and the surface temperature of the wire is evenly distributed, thereby improving the quality and efficiency of the insulation coating and ensuring the quality of wire production.
