Description

Technical Field

[0001] This utility model relates to the technical field of cable insulation material forming equipment, and in particular to a cable insulation material forming equipment. Background Technology

[0002] Cables, as critical lines for power transmission and communication, consist of multiple metal conductors or optical fibers tightly wrapped in insulating material. The insulation layer bears the heavy responsibility of preventing current leakage and avoiding short circuits, while also protecting the internal metal conductors from various types of damage. However, the molding equipment currently used to produce cable insulation materials has revealed many problems. In actual production, wear and tear on the equipment molds after long-term use, as well as the difficulty in achieving precise temperature control, will seriously affect the key quality indicators of cable insulation materials, such as thickness uniformity and surface flatness. Once these indicators deviate, the insulation performance of the cable cannot be maintained stably, leading to a decline in the overall quality of the cable. In applications in the power and communication fields, it is difficult to guarantee stable and efficient transmission. Utility Model Content

A discharge pipe is fixedly connected to the right side of the outer surface. A metal cable spraying structure is fixedly connected to the end of the discharge pipe away from the heating material barrel. A front seat frame and a rear seat frame are fixedly connected from front to back on the upper right side of the base table. A cable roller is movably connected through the middle of the inner left wall and the middle of the inner right wall of the rear seat frame. A cable body is fixedly connected to the front of the outer surface of the cable roller. A driver is fixedly connected to the right end of the front seat frame. The output end of the driver passes through the lower right end of the front seat frame and is fixedly connected to a front roller. The left end of the front roller is movably connected to the front seat frame through a bearing.

[0006] The stirring and extrusion device includes a cylinder, which is fixedly connected to the upper end of the frame. The output end of the cylinder passes through the upper right part of the frame and is fixedly connected to an upper plate. The lower left and lower right parts of the upper plate are both provided with circular grooves. A rubber extrusion disc is fixedly connected to the lower end of the upper plate. The lower left and lower right parts of the rubber extrusion disc are both provided with through circular holes. The two circular holes are located directly below the two circular grooves. Servo motors are fixedly connected to the upper left and upper right parts of the upper plate. The output ends of the two servo motors pass through the upper end of the upper plate and are fixedly connected to stirring blades.

[0007] Preferably, the two stirring blades do not contact the upper plate and the rubber extrusion plate through two circular grooves and a circular hole. The lower end face of the two circular grooves is flush with the lower end face of the stirring blades. The diameter area of ​​the rubber extrusion plate is equal to the inner diameter area of ​​the heating material barrel.

[0008] By adopting the above technical solution: the cylinder drives the upper plate to move up and down, the rubber extrusion plate is adapted to the heating material barrel, which can effectively extrude the material, and the servo motor drives the stirring blade to rotate without contacting the upper plate and the rubber extrusion plate, which can fully stir the material during extrusion, improve the material mixing uniformity and processing effect.

[0009] Preferably, the metal cable spraying structure includes an outer protective frame, with a pull hole through the front and rear of the outer protective frame at the center of the front end. A sealing gasket is embedded and fixedly connected in both pull holes, and an insulating spraying component is inserted and fixedly connected to the center of the left end of the outer protective frame.

[0010] By adopting the above technical solutions: the outer protective frame provides support for the whole, the pull hole facilitates the passage of metal cables, the sealing ring gasket prevents leakage of the spraying material, and the insulation spraying component can perform insulation spraying on the cable to ensure the spraying effect.

[0011] Preferably, the insulating spraying assembly includes a fixing head, the left end of which is fixedly connected to the right end of the discharge pipe, the right side of which extends into the outer protective frame and is fixedly connected to two connecting pipes, and annular spray pipes are fixedly connected to the ends of the two connecting pipes away from the fixing head, and several through spray holes are opened on the inner walls of the two annular spray pipes.

[0012] By adopting the above technical solution: the fixed head is connected to the discharge pipe to introduce the insulating material, and the connecting pipe transmits the material to the annular spray pipe.

The nozzles are distributed in a ring array, which can achieve uniform spraying from 360 degrees, making the cable insulation layer thickness consistent and effectively improving the insulation performance.

[0015] Preferably, the end of the cable body away from the cable roller passes through the wire drawing hole into two annular nozzles and is fixedly connected to the rear part of the outer surface of the front roller. The two sealing rings are tightly pressed against the outer surface of the cable body but not fixed.

[0016] By adopting the above technical solution, the cable body passes through the pull hole and the annular spray pipe, which can ensure the stability of the position during the spraying process. The sealing ring gasket abuts against the cable, which can prevent the leakage of spraying material, ensure a clean working environment, avoid material waste, and make the spraying work efficient and orderly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In this utility model, the cylinder drives the upper plate and the rubber extrusion plate to move up and down. The diameter of the rubber extrusion plate is adapted to the inner diameter of the heating material barrel, which can effectively extrude the material in the barrel, expel air, reduce air bubbles, and improve the density of the material. At the same time, the servo motor drives the stirring blades to rotate. The stirring blades do not contact the upper plate and the rubber extrusion plate, ensuring the stability of the stirring process. The stirring blades penetrate into the material through the circular grooves and holes to fully stir the insulating material, so that the different components are evenly mixed and the separation is avoided. Thus, this device integrates the functions of stirring and extrusion, which not only improves the uniformity of the insulating material, but also enhances the density of the material, providing high-quality material for the subsequent forming of the cable insulation layer and ensuring the insulation performance of the cable.

[0019] 2. In this utility model, the cable can pass smoothly through the pull hole, and the sealing ring gasket fits tightly against the cable to prevent leakage of the insulating spray material, ensuring a clean working environment and avoiding material waste. In the insulating spray assembly, the fixed head is connected to the discharge pipe, which allows the material to be smoothly introduced into the connecting pipe and then transported to the annular spray pipe. The inner wall of the annular spray pipe is in close contact with the outer surface of the cable, and the spray holes are distributed in a ring array, which can perform 360-degree all-round and uniform insulating spraying on the cable, ensuring that the insulation layer thickness is consistent and there are no dead corners, significantly improving the insulation performance of the cable and ensuring the stability and safety of power and communication transmission.
