Description

Technical Field

[0001] This utility model relates to the technical field of wire production equipment, and in particular to a wire sheath extrusion and winding device. Background Technology

[0002] In the wire and cable manufacturing industry, wire sheath extrusion and winding equipment is a core device at the end of the production line. Its function is to wind the wires covered with insulation or sheathing layers into spools for subsequent storage, transportation, and use. Traditional winding equipment uses a counterweight block to press down on the wire before winding, keeping the wire under tension. However, the tension control precision of existing counterweight blocks is insufficient, which can easily lead to loose winding. Furthermore, the loose areas can spread due to vibration during handling, causing the entire spool of wire to collapse. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a wire sheath extrusion and winding device that can achieve high-precision tension control and avoid the problem of loose wire winding.

[0004] An electrical wire sheath extrusion and winding device according to an embodiment of the present invention includes: an extrusion mechanism, comprising an extruder for extruding outer sheath onto a wire core; a cooling and forming mechanism disposed in the discharge direction of the extruder, comprising a cooling water tank and a water inlet pipe for injecting water into the cooling water tank, wherein an electrical wire is accommodated inside the cooling water tank; a tensioning mechanism disposed in the discharge direction of the cooling and forming mechanism, comprising a rocker arm, an electric cylinder for driving the rocker arm to swing, and a proximity switch for detecting the position of the rocker arm, wherein a pressure roller is disposed at the free end of the rocker arm, and when the rocker arm deviates from the proximity switch, the proximity switch feeds back an electrical signal to a controller, and the electric cylinder drives the rocker arm to swing, causing the pressure roller to press the electrical wire; and a winding mechanism disposed in the discharge direction of the tensioning mechanism, comprising a winding reel and a motor for driving the winding reel to rotate, wherein the winding reel is used to wind the electrical wire.

[0005] An electrical wire sheath extrusion and winding device according to an embodiment of the present utility model has at least the following beneficial effects:

[0006] 1. This utility model, by setting up an extrusion mechanism and a cooling and forming mechanism, conveys the wire core through the extrusion mechanism, uses the extruder to extrude the outer sheath of the wire core, the outer sheath forms the insulation layer of the wire core, and the wire with the extruded outer sheath passes through the cooling and forming mechanism. Cooling water is injected into the cooling water tank through the water inlet pipe. The surface temperature of the wire is high after it comes out of the extruder, so the wire passes through the cooling water tank, which cools down the wire and shapes the outer sheath of the wire to meet the shape requirements of the wire.

[0007] 2. This utility model, by setting up a tensioning mechanism and a winding mechanism, allows the wire to pass through the tensioning mechanism, which allows a pressure roller to be placed at the free end of the swing arm. The electric cylinder drives the swing arm to swing, causing the pressure roller to press down on the wire. The wire is in a taut state between the winding mechanism and the cooling and forming mechanism. The motor drives the winding reel to rotate, and the winding reel takes in the wire, making it less likely for the wire on the winding reel to loosen. In addition, a proximity switch can detect the position of the swing arm. When the position of the swing arm changes, the electric cylinder drives the swing arm to swing, thereby monitoring the changes in wire tension in real time and automatically adjusting the pressure roller pressure to achieve high-precision tension control. Furthermore, compared with the traditional counterweight pressing method, it can avoid the problem of loose winding caused by tension fluctuations and effectively prevent the collapse of the winding.

The upper felt and the lower felt are arranged close to the tensioning mechanism, and the upper felt and the lower felt adsorb water film on the surface of the electrical wire.

[0014] According to an embodiment of the present invention, a wire sheath extrusion and winding device is provided between the cooling and forming mechanism and the tensioning mechanism. The tensioning mechanism includes two wire guide rollers, which are horizontally distributed. The radial outer surface of each wire guide roller has a plurality of annular grooves, which are distributed along the axial direction of the wire guide rollers.

[0028] The following description, in conjunction with the accompanying drawings, describes an embodiment of an electrical wire sheath extrusion and winding device according to the present invention.

[0029] Reference Figure 1The present invention aims to provide an embodiment of an electrical wire sheath extrusion and winding device.

[0030] An embodiment of the present invention provides a wire sheath extrusion and winding device, comprising an extrusion mechanism and a cooling and forming mechanism. The extrusion mechanism includes an extruder 100, which is used to extrude the outer sheath of the wire core. The cooling and forming mechanism is disposed in the discharge direction of the extruder 100 and includes a cooling water tank 110 and a water inlet pipe 120 for injecting water into the cooling water tank 110. The wire is accommodated inside the cooling water tank 110.

[0031] It is understood that this embodiment includes an extrusion mechanism and a cooling and forming mechanism. The wire core is conveyed through the extrusion mechanism, and the extruder 100 extrudes the outer sheath of the wire core. The outer sheath forms the insulation layer of the wire core. The wire with the extruded outer sheath passes through the cooling and forming mechanism. Cooling water is injected into the cooling water tank 110 through the water inlet pipe 120. The surface temperature of the wire is high after it comes out of the extruder 100. The wire passes through the cooling water tank 110, which cools the wire down and shapes the outer sheath of the wire to meet the shape requirements of the wire.

[0032] This utility model provides an embodiment of a wire sheath extrusion and winding device, referring to... Figure 3 It also includes a tensioning mechanism, which is located in the discharge direction of the cooling and forming mechanism. The tensioning mechanism includes a swing arm 130, an electric cylinder 140 that drives the swing arm 130 to swing, and a proximity switch 150 for detecting the position of the swing arm 130. A pressure roller 160 is provided at the free end of the swing arm 130. When the swing arm 130 deviates from the proximity switch 150, the proximity switch 150 feeds back an electrical signal to the controller, and the electric cylinder 140 drives the swing arm 130 to swing, so that the pressure roller 160 presses the wire. The winding mechanism is located in the discharge direction of the tensioning mechanism. The winding mechanism includes a winding reel 170 and a motor 180 that drives the winding reel 170 to rotate. The winding reel 170 is used to wind up the wire.

[0033] It is understood that this embodiment includes a tensioning mechanism and a winding mechanism. The wire passes through the tensioning mechanism, allowing a pressure roller 160 to be positioned at the free end of the swing arm 130. The electric cylinder 140 drives the swing arm 130 to swing, causing the pressure roller 160 to press down on the wire. The wire is in a taut state between the winding mechanism and the cooling and forming mechanism. The motor 180 drives the winding reel 170 to rotate, and the winding reel 170 takes in the wire, making it less prone to loosening. Furthermore, the proximity switch 150 can detect the position of the swing arm 130. Changes in the position of the swing arm 130 are triggered by the electric cylinder 140 to swing the swing arm 130, thereby monitoring the wire tension changes in real time and automatically adjusting the pressure of the pressure roller 160 to achieve high-precision tension control. In addition, compared to the traditional counterweight pressing method, this avoids the problem of loose winding caused by tension fluctuations and effectively prevents coil collapse.

[0034] In some embodiments of this utility model, a rolling mechanism is also provided between the extrusion mechanism and the cooling molding mechanism. The rolling mechanism includes a support wheel 190, an adjustment wheel 200 located above the support wheel 190, and a spring 210 that drives the adjustment wheel 200 to approach the support wheel 190. The adjustment wheel 200 and the support wheel 190 clamp the rolled wire.

[0035] Understandably, by using spring 210 to drive pressure roller 160 downward, adjustment roller 200 and support roller 190 clamp and roll the wire, automatically adapting to different wire diameters, and uniformly rolling the extruded wire sheath, it can eliminate tiny air bubbles or wrinkles on the sheath, improve surface smoothness, and at the same time avoid local deformation caused by cooling and shrinkage.

[0036] In some embodiments of this utility model, reference is made to Figure 2 The rolling mechanism includes a mounting frame 330 and a rotating frame 340 rotatably mounted on the mounting frame 330. The mounting frame 330 is provided with a connecting part. A spring 210 connects the rotating frame 340 and the connecting part. The free end of the rotating frame 340 is rotatably connected to the adjusting wheel 200.

Furthermore, the spring 210 is installed between the rotating frame 340 and the connecting part, making the replacement and installation of the spring 210 more convenient.

[0038] In some embodiments of this utility model, the tensioning mechanism further includes a first guide wheel 220 and a second guide wheel 230, which are located above the pressure wheel 160. The wire can pass through the first guide wheel 220, the pressure wheel 160 and the second guide wheel 230 in sequence.

[0039] It is understood that in this embodiment, a first guide wheel 220 and a second guide wheel 230 are provided. The first guide wheel 220 and the second guide wheel 230 form a triangular winding path with the pressure wheel 160, which increases the contact angle between the wire and the pressure wheel 160 and improves the tension control sensitivity.

[0040] In some embodiments of this utility model, the tensioning mechanism further includes a bracket 240, the fixed end of the electric cylinder 140 is hinged to the bracket 240, the extended end of the electric cylinder 140 is provided with a rotating shaft 250, and the pressure roller 160 is coaxially connected to the rotating shaft 250.

[0041] Understandably, the extension end of the electric cylinder 140 can be hinged to the free end of the rocker arm 130 using the pivot 250, and the pressure roller 160 can be set at the hinge point between the extension end of the electric cylinder 140 and the free end of the rocker arm 130, so that when the electric cylinder 140 extends, the electric cylinder 140 and the rocker arm 130 swing, causing the pressure roller 160 to press the wire tightly.

[0042] In some embodiments of this utility model, the rocker arm 130 is provided with a metal part 260, which is used to be arranged opposite to the proximity switch 150.

[0043] Understandably, the non-contact detection of the metal part 260 and proximity switch 150 offers higher durability and anti-interference capabilities compared to mechanical contacts. The metal sensing area can accurately detect the offset of the lever 130, improving signal feedback accuracy, avoiding false triggering, and ensuring system control stability.

[0044] In some embodiments of this utility model, reference is made to Figure 4 The outer wall of the cooling water tank 110 has an upper felt 270 and a lower felt 280. The upper felt 270 and the lower felt 280 are arranged close to the tensioning mechanism. The upper felt 270 and the lower felt 280 adsorb water film on the surface of the wires.

[0045] It is understood that this embodiment is equipped with an upper felt 270 and a lower felt 280. The clamping and adsorption design of the upper felt 270 and the lower felt 280 achieves double-sided dehydration, effectively removing residual water film from the surface of the wire. In addition, the felt material is highly flexible, which ensures water absorption efficiency while avoiding scratching the wire sheath, and at the same time reduces the splashing of cooling water and environmental pollution.

[0046] In some embodiments of this utility model, a tensioning mechanism is provided between the cooling and forming mechanism and the tensioning mechanism. The tensioning mechanism includes two wire guide rollers 290, which are horizontally distributed. The radial outer surface of the wire guide rollers 290 has a plurality of annular grooves 300, which are distributed along the axial direction of the wire guide rollers 290. The wire is wound around the annular grooves 300 between the two wire guide rollers 290.

[0047] It is understood that this embodiment sets two wire guide rollers 290, and the annular groove 300 structure of the two wire guide rollers 290 performs multi-segment stretching and shaping of the wire to eliminate internal stress after cooling and shrinkage.

[0048] In some embodiments of this utility model, the discharge end of the tensioning mechanism is provided with a limiting roller 310. The limiting roller 310 is used to restrict the horizontal position of the wire. Therefore, the limiting roller 310 constrains the horizontal degree of freedom of the wire, ensuring that the wire is strictly arranged along the axial direction when it is wound up.

[0049] In some embodiments of this utility model, a drain pipe 320 is provided at the bottom of the cooling water tank 110, and the outlet end of the drain pipe 320 is connected to a water pool.

[0050] Understandably, the water in the cooling water tank 110 is discharged into the water pool through the drain pipe 320, realizing the recycling and reuse of cooling water and saving water resources.
