Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of pre-twisted wire mechanism technology, and more specifically, to a pre-twisted wire mechanism for a cable stranding machine. Background Technology

[0002] A cable is an electrical energy or signal transmission device consisting of a conductor, insulation layer, sheath, and other auxiliary structures. It is widely used in many fields such as power, communication, and construction. In the production of cables, a cable stranding machine is usually used to twist multiple single wires (such as copper wires or aluminum wires) together according to certain rules to form cable cores or complete cables.

[0003] Because the production of cables requires a series of steps, after multiple materials are twisted together, insulation and withstand voltage tests are required on their surfaces. Therefore, the cable production process requires pre-twisting, which involves twisting multiple materials together. During the twisting process, a traction assembly is usually used to wind and move the twisted portion of the cable forward, thereby winding it onto a reel for easy handling and storage.

[0004] After one of the reels has been wound to a fixed capacity, the full reel is usually removed and replaced with a new one. When removing and moving smaller reels, they are usually done manually because the reels contain cables, which increases their weight and makes them more difficult for workers to move. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a pre-twisting mechanism for a cable stranding machine, which solves the technical problem in the prior art that when one of the winding reels is fully laid out and needs to be disassembled and replaced, it requires manual handling by workers, which is quite laborious.

[0006] According to one aspect, at least one embodiment of this disclosure provides a pre-twisting mechanism for a cable stranding machine, including a winding mechanism mounted on a base plate, and further including a winding assembly, a tray cover, a reciprocating translation assembly, and a deflecting assembly. The winding assembly is disposed on the base plate for winding the stranded cable. The tray cover is disposed below the winding assembly for transporting the wound reel. The reciprocating translation assembly is disposed on the side of the base plate. The deflecting assembly is disposed on the reciprocating translation assembly, and the tray cover is disposed on the deflecting assembly via a lifting assembly for rotating the wound reel on the tray cover.

[0007] Furthermore, the winding assembly includes a movable plate, a rotating shaft, and a first motor. Two movable plates are slidably mounted on the base plate, and the rotating shaft is rotatably mounted on the side of each movable plate. The winding reel is detachably mounted on the two rotating shafts via a flange. The first motor is mounted on the side of one of the movable plates, and the output end of the first motor is coaxially connected to one of the rotating shafts.

[0008] Furthermore, the reciprocating translation assembly includes a reciprocating lead screw, a second motor, and a crescent-shaped slider. The reciprocating lead screw is rotatably mounted on the side of the base plate via a mounting plate. The second motor is mounted on the side of one of the mounting plates, and the output end of the second motor is coaxially connected to the reciprocating lead screw. The crescent-shaped slider is mounted on the reciprocating lead screw and is adapted to the reciprocating lead screw.

[0009] Furthermore, the steering assembly includes a rotating ring, a steering plate, a connecting rod, and an eccentric block. The rotating ring is slidably mounted on the base plate, and a circular groove is formed on the inner sidewall of the rotating ring. The steering plate is slidably mounted in the circular groove of the rotating ring. The connecting rod is fixedly installed between the rotating ring and the crescent-shaped slider. Both moving plates are respectively mounted on the two connecting rods through a connecting assembly. The eccentric block is fixedly installed at the eccentric position of the steering plate.

[0010] Furthermore, the lifting assembly includes a mounting cover and an electric cylinder. The mounting cover is fixedly installed on the top of the eccentric block, and two electric cylinders are mounted on the mounting cover. The output end of the electric cylinder is fixedly connected to the bottom end of the tray cover.

[0011] Furthermore, the connecting assembly includes a connecting frame and mounting bolts. The connecting frame is fixedly installed on the side of each connecting rod, and the side of each of the two connecting frames is respectively attached to the inner side of the two movable plates. The mounting bolts are threaded onto the side of the connecting frame and the movable plate.

[0012] To further secure the steering plate to the rotating ring, both the steering plate and the rotating ring have mounting holes on their sides, and mounting rods are detachably installed in the mounting holes.

[0013] To enable the crescent-shaped slider to move horizontally on the reciprocating lead screw, a groove is further provided on the side of the base plate, and the crescent-shaped slider is slidably installed in the groove of the base plate by means of a limiting block.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, after winding is completed, the pallet cover can be driven to fit the bottom of the winding reel by the lifting component according to the thickness of the winding reel, and then the winding reel can be removed. This allows the pallet cover to support the winding reel, thus avoiding the need for manual support and lifting after the winding reel is removed. After support is completed, the pallet cover and winding reel can be rotated to the side of the base plate by the steering component, making it easy to remove them with tools and avoiding the need for manual handling to remove them from the winding component.

[0018] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0019] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-6As shown, it illustrates a pre-twisting mechanism for a cable stranding machine according to an embodiment of the present disclosure. It includes a winding mechanism 1 mounted on a base plate 18, and further includes a winding assembly, a tray cover 2, a reciprocating translation assembly, and a steering assembly. The winding assembly is disposed on the base plate 18 and is used to wind the stranded cable. The tray cover 2 is disposed below the winding assembly and is used to transport the wound reel. The reciprocating translation assembly is disposed on the side of the base plate 18, and the steering assembly is disposed on the reciprocating translation assembly. The tray cover 2 is disposed on the steering assembly via a lifting assembly and is used to rotate the wound reel on the tray cover 2.

[0025] like Figure 1 As shown, when twisting the cable, the twisting can be performed by the winding mechanism 1 on the base plate 18. Copper or aluminum wires are passed through several holes on the rotating plate, and the cable core can pass through the center of the rotating plate. The rotating plate drives several copper wires to rotate, thereby winding them around the cable core at the center. The copper wires are wound and transported by the guide wheel. During the rotation, several guide wheels at the rear end also rotate synchronously. Then, the copper wires and the cable core are passed through the same wire hole. The copper wires that pass through the wire hole are wound around the cable core and twisted into a strand. This is all existing technology and will not be described in detail. One end of the cable core that has passed through the wire hole and is wound is wound on the take-up reel, and the take-up reel is installed on the take-up assembly through the flange.

[0026] like Figure 2 As shown, during the twisting process, the cable can be wound up using a winding assembly. The winding assembly includes a movable plate 3, a rotating shaft 4, and a first motor 5. Two movable plates 3 are slidably mounted on the base plate 18. The rotating shaft 4 is rotatably mounted on the side of each movable plate 3, and the winding reel is detachably mounted on the two rotating shafts 4 via a flange. The first motor 5 is mounted on the side of one of the movable plates 3, and the output end of the first motor 5 is coaxially connected to one of the rotating shafts 4. Specifically, one end of the wound cable is wound onto the winding reel, and then the winding reel is mounted on the two rotating shafts 4 via a flange. By starting the first motor 5, the first motor 5 drives the rotating shaft 4 to rotate, and the rotating shaft 4 drives the winding reel to rotate between the two movable plates 3, thereby winding up the cable.

[0027] like Figure 3 , Figure 5 and Figure 6As shown, when winding the cable, the moving plate 3 can be connected to the reciprocating translation component through the connecting assembly, thereby ensuring that the moving plate 3 can drive the winding reel to move left and right during winding, so that the cable is evenly laid on the winding reel. The connecting assembly includes a connecting frame 15 and a mounting bolt 16. The connecting frame 15 is fixedly installed on the side of the connecting rod 11, and the side of the two connecting frames 15 respectively fits against the inner side of the two moving plates 3. The mounting bolt 16 is threadedly installed on the side of the connecting frame 15 and the moving plate 3. The reciprocating translation component includes a reciprocating screw 6, a second motor 7 and a crescent slider 8. The reciprocating screw 6 is rotatably installed on the side of the base plate 18 through the mounting plate 19. The second motor 7 is installed on the side of one of the mounting plates 19, and the output end of the second motor 7 is coaxially connected to the reciprocating screw 6. The crescent slider 8 is installed on the reciprocating screw 6 and is adapted to the reciprocating screw 6.

[0028] Specifically, the two movable plates 3 are moved to fit against the sides of the two connecting frames 15 respectively. Then, they are fixed by mounting bolts 16 threaded onto the sides of the movable plates 3 and the connecting frames 15. Then, the second motor 7 is started. The output end of the second motor 7 drives the reciprocating screw 6 between the two mounting plates 19 to rotate. It should be added that the crescent slider 8 is mounted on the reciprocating screw 6 by a reciprocating sleeve. Because the side of the base plate 18 has a groove, and the crescent slider 8 is slidably mounted in the groove of the base plate 18 by a limit block, the crescent slider 8 moves left and right on the reciprocating screw 6, thereby driving the connecting rod 11 and the connecting frame 15 to move, so that the cable is evenly laid on the winding reel.

[0029] After the installation is completed, the pallet cover 2 can be moved upward by the lifting assembly to fit the bottom of the take-up reel. The lifting assembly includes a mounting cover 13 and an electric cylinder 14. The mounting cover 13 is fixedly installed on the top of the eccentric block 12. Two electric cylinders 14 are installed on the mounting cover 13, and the output end of the electric cylinder 14 is fixedly connected to the bottom of the pallet cover 2. Specifically, when the electric cylinder 14 is started, the output end of the electric cylinder 14 moves the pallet cover 2 upward to fit the bottom of the take-up reel and then removes it. When the electric cylinder 14 is started, the output end of the electric cylinder 14 moves the pallet cover 2 and the take-up reel downward and then the mounting bolts 16 are removed. Then the two moving plates 3 are slid to both sides on the base plate 18.

[0030] like Figure 4As shown, after disassembly, the tray cover 2 and the take-up reel can be rotated by the steering assembly. Since the tray cover 2 and the take-up reel are initially located inside the base plate 18, after disassembly, the tray cover 2 and the take-up reel can be rotated to the other side of the base plate 18, which facilitates subsequent movement after disassembly. The steering assembly includes a rotating ring 9, a steering plate 10, a connecting rod 11, and an eccentric block 12. The rotating ring 9 is slidably mounted on the base plate 18, and a circular groove is provided on the inner side wall of the rotating ring 9. The steering plate 10 is slidably mounted in the circular groove of the rotating ring 9. The connecting rod 11 is fixedly installed between the rotating ring 9 and the crescent slider 8, and the two moving plates 3 are respectively set on the two connecting rods 11 through the connecting assembly. The eccentric block 12 is fixedly installed at the eccentric position of the steering plate 10.

[0031] Specifically, after disassembly, the steering plate 10 can be rotated to the position of the rotating ring 9, thereby rotating the steering plate 10 180° and rotating the take-up reel to the outside of the base plate 18. Then, the collection vehicle can be moved to the side of the chassis. By transporting the take-up reel into the collection vehicle, it can be moved to the required location. During the movement, the connection between the crescent slider 8 and the rotating ring 9 is made through the connecting rod 11, which can synchronously drive the rotating ring 9 to move on the base plate 18. The sides of the steering plate 10 and the rotating ring 9 are provided with fixing holes, and fixing rods 17 can be detachably installed in the fixing holes. During the movement, the fixing rods 17 can be inserted into the sides of the rotating ring 9 and the steering plate 10 to fix them. At this time, the pallet cover 2 is located directly below the take-up reel. After turning it around, the fixing rods 17 can also be inserted into the fixing holes on the other side of the rotating ring 9 and the steering plate 10 to prevent the pallet cover 2 from rotating during transportation.

[0032] Working principle: During stranding, copper or aluminum wires are passed through holes in rotating plates, with the cable core penetrating the center of the rotating plates. The rotating plates 10 drive several copper wires to rotate, winding them around the cable core at the center. These copper wires are fed and wound by guide wheels. During rotation, guide wheels at the rear also rotate synchronously. Then, the copper wires and cable core are passed through the same through-hole, and the copper wires passing through the through-hole are wound around the cable core and twisted into a single strand. One end of the wound cable is then wound onto a take-up reel. The take-up reel is then mounted on two rotating shafts 4 via flanges. Starting the first motor 5... A motor 5 drives a rotating shaft 4 to rotate, which in turn drives a take-up reel to rotate between two moving plates 3, thereby winding up the cable. At the same time as winding, a second motor 7 is started. The output end of the second motor 7 drives a reciprocating screw 6 between two mounting plates 19 to rotate, and the crescent-shaped slider 8 moves left and right on the reciprocating screw 6, which in turn drives the connecting rod 11 and the connecting frame 15 to move, so that the cable is evenly laid on the take-up reel. At the same time, because the connecting rod 11 connects the crescent-shaped slider 8 and the rotating ring 9, it can synchronously drive the rotating ring 9 to move synchronously on the base plate 18. During the movement, the fixing rod 17 is inserted into the fixing hole of the rotating ring 9 and the turning plate 10.

[0033] After winding is complete, start the electric cylinder 14. The output end of the electric cylinder 14 drives the pallet cover 2 to move upward and fit it. Then remove the winding reel. Start the electric cylinder 14 again. The output end of the electric cylinder 14 drives the pallet cover 2 and the winding reel to move downward. Then remove the mounting bolts 16. Then slide the two moving plates 3 on the base plate 18 to both sides. Then pull out the fixing rod 17 and rotate the steering plate 10 to rotate the winding reel and the pallet cover 2 to the side of the base plate 18 for easy movement and handling.

[0034] It should be added that the reciprocating screw is equipped with a telescopic protective sleeve to protect it. Furthermore, all electrical equipment within this mechanism is controlled by the power supply and control system within the factory. For example, the electric cylinder 1414, the first motor 5, and the second motor 7 are powered by the factory's power supply system. The DC or AC power is matched according to the model of the first motor 5 and the second motor 7 to ensure normal operation. The two electric cylinders 14 can be synchronously controlled by a controller, such as a PL or PC-based controller. The two electric cylinders 14 are electrically connected to the controller via wires. One electric cylinder 14 is designated as the master cylinder, and the other electric cylinders 14 as slave cylinders. The slave cylinders can move synchronously following the output of the master cylinder. The controller is also electrically connected to an encoder via wires. The master cylinder sets the trajectory, and the slave cylinders compensate for deviations through encoder feedback, thus ensuring synchronous movement of the outputs of the two electric cylinders 14.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
