Description

Technical Field

[0001] This application relates to the field of cable technology, and specifically to a filling mold for extruded filling type metal-sheathed cables. Background Technology

[0002] Metal-sheathed cables refer to power cables with a metal protective layer wrapped around the outside of the cable insulation layer. They are mainly used for waterproofing, mechanical protection, and current conduction. To prevent moisture from penetrating along the longitudinal and radial directions of the cable, grease needs to be filled into the gaps between the metal wires (such as copper conductors, aluminum foil, and steel armor) to form a physical barrier, preventing moisture from penetrating along the longitudinal and radial directions of the cable. At the same time, it protects the cable components from external environmental corrosion, forming a robust protective layer. A filling mold is required when filling the grease. In the use of existing grease molds, the cable to be filled with grease passes through the grease-filled filling box, thus completing the grease filling process. When the cable passes through the grease-filled filling box, air will enter, which will then generate air bubbles. These air bubbles will prevent the grease from fully filling the gaps in the metal-sheathed cable, thus affecting the waterproofing and corrosion resistance of the cable core. Utility Model Content

[0003] The purpose of this utility model is to provide a filling mold for extrusion-filled metal-sheathed cables, which addresses the technical problem that when the cable passes through a filling box filled with grease, air may enter, which in turn will generate air bubbles. These air bubbles will prevent the grease from fully filling the gaps in the metal-sheathed cable, thus affecting the waterproof and corrosion-resistant properties of the cable core.

[0004] The technical solution of this utility model is as follows: A filling mold for extruded and filled metal-sheathed cables includes a filling mold with a filling cavity for the cable to pass through. The filling mold has an oil inlet and an oil outlet, the interiors of which are connected to the interior of the filling cavity. The filling mold also has a cable inlet and a cable outlet, which are coaxial and connected to the interior of the filling cavity. A first mounting bracket and a second mounting bracket are fixedly installed on one side of the filling mold. A clamping mechanism is provided at the cable inlet, comprising clamping rollers and an elastic layer arranged side-by-side. The clamping rollers are rotatably mounted inside the first mounting bracket, and the elastic layer is located on the outer surface of the clamping rollers. The clamping mechanism is used to clamp... The cable is clamped and passed through. The cable outlet of the filling mold is equipped with a tightening mechanism, which includes two rollers arranged side by side. The outer surface of the rollers contacts the outer surface of the cable. The rollers are rotatably mounted inside the second mounting bracket. The tightening mechanism also includes a power source, which is coaxially arranged with the rollers and the output shaft of the power source is fixedly connected to the rollers. The tightening mechanism is used to tighten the cable. The tightening mechanism also includes a guide and limiting mechanism, which is located at the cable outlet. The guide and limiting mechanism includes a fixed plate with a limiting groove. The fixed plate is fixedly installed at the cable outlet of the filling mold. The inside of the limiting groove contacts the surface of the cable. The guide and limiting mechanism is used to limit the cable between the two rollers.

[0005] The beneficial effects of this technical solution are as follows: When using an extrusion-filled metal-sheathed cable filling mold, the cable with a metal sheath enters the mold through the inlet. Through the action of the tightening mechanism, the rollers in the tightening mechanism, driven by a power source, rotate. One roller rotates, causing the cable to rotate, which in turn drives the other roller to rotate, resulting in the two rollers rotating in opposite directions. This applies appropriate tightening force to the cable, creating a certain pressure environment inside the cable and squeezing out air bubbles. This helps the grease to penetrate the cable more evenly and fully, improving the filling effect and quality, and thus enhancing the overall performance and service life of the cable. During the filling process, the clamping mechanism, through the cooperation of the clamping rollers and the elastic layer, allows the elastic layer to hold the cable, ensuring that each section of the cable is tightened. The clamping rollers ensure continuous movement of the cable, guaranteeing continuous tightening. The guide and limiting mechanism, with its limiting grooves, limits the outer surface of the cable, ensuring that the cable floats up and down during tightening, thus guaranteeing stability during cable production.

[0006] Preferably, the limiting groove has a slot, and at least one roller is rotatably mounted inside the slot.

[0007] Preferably, a first rotating shaft is fixedly connected inside the clamping roller, and first fixing holes are opened on both sides of the first mounting bracket. The first rotating shaft is rotatably inserted into the first fixing hole. A first limiting ring is fixed on the first rotating shaft. A first limiting groove is opened on one side of the first fixing hole. The first limiting ring is located inside the first limiting groove, and the diameter of the first limiting ring is larger than the diameter of the first insertion hole for axial fixation.

[0008] Preferably, a second rotating shaft is fixedly connected inside the roller, and second fixing holes are provided on both sides of the second mounting bracket. The second rotating shaft is rotatably inserted into the second fixing hole. A second limiting ring is fixed on the second rotating shaft. A second limiting groove is provided on one side of the second fixing hole. The second limiting ring is located inside the second limiting groove, and the diameter of the second limiting ring is larger than the diameter of the second insertion hole for axial fixation.

[0009] Preferably, the power source is an electric motor, the output shaft of the motor is coaxial with the second rotating shaft, and the output shaft of the motor is fixedly connected to one of the second rotating shafts.

[0010] Preferably, the distance between the axes of the two rollers is less than the diameter of the cable.

[0011] Preferably, one of the clamping rollers is slidably mounted on the first mounting bracket by bolts. Attached Figure Description

[0017] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0018] A specific embodiment of the extrusion-filled metal-sheathed cable filling mold of this utility model is as follows: Figures 1-4As shown, a filling mold for extruded and filled metal-sheathed cables includes a filling mold 1 with a filling cavity 2 for the cable to pass through. The filling mold 1 has an oil inlet and an oil outlet, the interiors of which are connected to the interior of the filling cavity 2. The filling mold 1 also has a cable inlet and a cable outlet, which are coaxial and connected to the interior of the filling cavity 2. A first mounting bracket 3 and a second mounting bracket 4 are fixedly mounted on one side of the filling mold 1. The cable inlet is equipped with a clamping mechanism, which includes clamping rollers 5 arranged side-by-side and an elastic layer. The clamping rollers 5 are rotatably mounted inside the first mounting bracket 3, and the elastic layer is located on the outer surface of the clamping rollers 5. The clamping mechanism is used to clamp the cable. The cable outlet of the filling mold 1 is equipped with a tightening mechanism, which includes two rollers 6 arranged side by side. The outer surface of the rollers 6 is in contact with the outer surface of the cable. The rollers 6 are rotatably mounted inside the second mounting bracket 4. The tightening mechanism also includes a power source, which is coaxially arranged with the rollers 6 and the output shaft of the power source is fixedly connected to the rollers 6. The tightening mechanism is used to tighten the cable. The tightening mechanism also includes a guide and limiting mechanism, which is located at the cable outlet. The guide and limiting mechanism includes a fixing plate 7, on which a limiting groove 8 is formed. The fixing plate 7 is fixedly installed with the cable outlet of the filling mold 1. The inside of the limiting groove 8 is in contact with the surface of the cable. The guide and limiting mechanism is used to limit the cable between the two rollers 6.

[0019] The guide and limit mechanism not only confines the cable between the two rollers 6, but also guides it to prevent the cable from tilting.

[0020] The limiting groove 8 has a slot, and at least one roller 801 is rotatably mounted inside the slot.

[0021] When the roller 6 tightens the cable, the cable will float. The limiting groove 8 is set and acts on the surface of the cable, so that the cable is between the two rollers 6, thus making the cable more stable when moving.

[0022] The roller 801 makes the cable flow more smoothly when it comes out of the outlet.

[0023] The clamping roller 5 is internally fixedly connected to a first rotating shaft. The first mounting bracket 3 has first fixing holes on both sides. The first rotating shaft is rotatably inserted into the first fixing hole. A first limiting ring is fixed on the first rotating shaft. A first limiting groove is opened on one side of the first fixing hole. The first limiting ring is located inside the first limiting groove, and the diameter of the first limiting ring is larger than the diameter of the first insertion hole, thereby effectively preventing the first insertion post from coming out of the first insertion hole.

[0024] The roller 6 is internally fixedly connected to a second rotating shaft. The second mounting bracket 4 has second fixing holes on both sides. The second rotating shaft is rotatably inserted into the second fixing hole. A second limiting ring is fixed on the second rotating shaft. A second limiting groove is opened on one side of the second fixing hole. The second limiting ring is located inside the second limiting groove, and the diameter of the second limiting ring is larger than the diameter of the second insertion hole, thereby effectively preventing the second insertion post from coming out of the second insertion hole.

[0025] The power source is an electric motor, the output shaft of which is coaxial with the second rotating shaft, and the output shaft of the motor is fixedly connected to one of the second rotating shafts.

[0026] The distance between the axes of the two rollers 6 is less than the diameter of the cable.

[0027] By setting the axial distance between the two rollers 6 to be less than the diameter of the cable, the two rollers 6 can tighten the cable as it passes through them.

[0028] like Figure 3 As shown, one of the clamping rollers 5 is slidably mounted on the first mounting bracket 3 by bolts.

[0029] One of the clamping rollers 5 is slidably mounted on the first mounting frame 3, thereby allowing the distance between the clamping rollers 5 to be adjusted, and thus enabling the device to clamp cables of different diameters.

[0030] During use, the cable enters the filling mold 1 through the cable inlet, and the grease is added into the filling mold through the oil inlet. Then, the motor is started, and the motor drives one of the rollers 6 to rotate. The rotation of one roller 6 drives the cable to rotate, and the rotation of the cable drives the other roller 6 to rotate, so that the two rollers 6 rotate in opposite directions. The two rollers 6 moving in opposite directions can tighten the cable, so that the cable can expel the air bubbles inside the filling cavity before entering the filling cavity. At the same time, a certain pressure environment is formed inside the cable, so that the grease is filled more fully and evenly. During the tightening process, the clamping roller 5 also rotates. The elastic layer on the clamping roller 5 can clamp the cable. The cooperation between the clamping roller 3 and the elastic layer ensures that the cable inside the filling cavity 2 is in a tightened state and does not affect the front section of the cable entering from the inlet. The cable filled with grease comes out from the outlet.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
