Description

Technical Field

[0001] This utility model relates to the field of wire and cable production technology, and in particular to a cage stranding machine for producing flame-retardant cables and wires. Background Technology

[0002] Existing cage stranding machines used in the production of flame-retardant cables and wires are mechanical devices that strand multiple cables together and can organize the stranded wires for orderly winding. However, they can only strand cables of the same size, or require the replacement of some parts to strand cables of different sizes. For example, a multi-core cage stranding machine for cable production disclosed in Chinese patent application number CN202420261694.3 can use a motor to drive the take-up roller to wind up the wire. While the motor is winding up the wire, the inner hole block of the take-up roller slides back and forth to organize the wire winding and prevent the wire winding from becoming disordered. However, the size of the take-up drum is fixed and can only be used to strand cables of the same size. When the cable size is too large, the take-up drum needs to be replaced, which is relatively troublesome to operate and has limited use. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a cage stranding machine for the production of flame-retardant cables and wires. It is equipped with an openable limiting ring, and the opening size of the limiting ring can be controlled according to the size of the stranded cable, which is convenient to adapt to cables of different diameters and increases the versatility of the device. After the limiting ring is opened, a limiting block is used to keep the limiting ring connected together, which effectively prevents the cable from getting stuck in the gap between the limiting rings during the stranding process, thus preventing the cable from being stranded and enhancing the function of the limiting ring.

[0004] This utility model also provides a cage stranding machine for producing flame-retardant cables and wires, comprising: a base, a motor 1 fixedly connected to the upper surface of the base, a shaft cylinder 1 fixedly connected to the output end of the motor 1, a belt drivingly connected to one side surface of the shaft cylinder, a shaft cylinder 2 drivingly connected to the end of the belt away from the shaft cylinder 1, a turntable fixedly connected to the side surface of the shaft cylinder 2, two turntables symmetrically distributed, a fixing plate fixedly connected between the two turntables, and a guide hole provided on the side surface of the other turntable;

[0005] The cable take-up drum has a rotating block rotatably connected to its side surface. A threaded cylinder is threadedly connected to the inner surface of the rotating block. A sliding rod is fixedly connected to the end of the threaded cylinder away from the rotating block. A sliding groove block is slidably connected to the side surface of the sliding rod. A sleeve is fixedly connected to the end of the sliding groove block away from the sliding rod. A limit ring is fixedly connected to the end of the sleeve away from the sliding groove block. A limit locking block is fixedly connected to the side surface of the limit ring. A slot is provided on the inner side wall of the limit ring. These components allow the limit ring to be opened to accommodate stranding cables of different sizes. After the limit ring is opened, the limit rings are connected together by the limit locking block to prevent the cable from getting stuck in the gaps between the limit rings during stranding.

[0006] According to the present invention, a cage stranding machine for producing flame-retardant cables and wires includes a second motor fixedly connected to the side surface of the base, and a screw threadedly connected to the output end of the second motor. Through these components, the second motor can drive the screw to rotate, facilitating the screw to drive the connecting plate to slide on the base.

[0007] According to the present invention, a cage winding machine for producing flame-retardant cables and wires includes a connecting plate threadedly connected to the side surface of the screw, and the upper surface of the connecting plate being fixedly connected to the take-up drum. These components allow the connecting plate to move the take-up drum, facilitating control of the distance between the cable stranding sections.

[0008] According to the present invention, a cage winding machine for producing flame-retardant cables and wires includes a bracket fixedly connected to the upper surface of the base, and a motor fixedly connected to the side surface of the bracket. Through these components, the motor can drive the winding drum to rotate on the bracket.

[0009] According to the present invention, a cage winding machine for producing flame-retardant cables and wires includes a winding drum fixedly connected to the output end of a third motor, the side surface of which is rotatably connected to a support. Using these components, the third motor can drive the winding drum to take in the twisted cable.

[0010] According to the present invention, a cage stranding machine for producing flame-retardant cables and wires has a rotating frame rotatably connected to the end of the shaft cylinder away from the motor, and the lower surface of the rotating frame is fixedly connected to the base. These components allow the shaft cylinder to be mounted on the rotating frame, facilitating the rotation of the turntable.

[0011] According to the present invention, a cage winding machine for producing flame-retardant cables and wires comprises a turntable whose side surface is rotatably connected to a rotating frame, a threaded cylinder whose side surface is slidably connected to a take-up drum, and a chute block whose side surface is slidably connected to a take-up drum. These components allow the turntable to rotate on the rotating frame and the threaded cylinder to slide within the take-up drum, thereby driving the sliding rod to open the sleeve and the limiting ring.

[0012] According to the present invention, a cage stranding machine for producing flame-retardant cables and wires includes multiple and evenly distributed limiting rings, with the side surface of the limiting block slidably connected to the adjacent limiting ring. These components allow the limiting block to open as the limiting ring moves, ensuring the limiting rings remain connected and preventing the cable from getting stuck in the gap between the limiting rings during stranding.

[0013] Beneficial effects:

[0014] Compared with existing technologies, the design incorporates an openable limiting ring, which allows for control over the opening size of the limiting ring according to the dimensions of the stranded cable. This facilitates adaptation to cables of different diameters, increasing the versatility of the device. Furthermore, after the limiting ring opens, a limiting block keeps the limiting rings connected, effectively preventing the cable from getting stuck in the gaps between the limiting rings during stranding and thus preventing the cable from being stranded. This enhances the functionality of the limiting ring. Attached Figure Description

[0028] Working principle: The cable-wound spool is fixed on the fixing plate 8. The cable is then inserted into the take-up spool 13 through the guide hole 9. The motor 14 drives the screw 10 to rotate according to the distance of each cable twisting section, moving the connecting plate 11 to the appropriate position. Then, according to the diameter of the twisted cable, the rotating block 22 is rotated, causing the threaded cylinder 21 to drive the sliding rod 20 to slide along the groove in the sliding block 19. This causes the sliding block 19 to open through the sleeve 18, opening the limiting ring 12. The limiting block 23 then... Driven by the positioning ring 12, it moves in the slot 24 and keeps the positioning ring 12 connected even after the positioning ring 12 opens, so that the cable will not get stuck in the gap between the positioning rings 12 during twisting and affect the use of the device. Then, the motor 12 is started, and the turntable 7 is driven to rotate under the action of the shaft cylinder 13, belt 4 and shaft cylinder 25 to twist the cable. The twisted cable is wound on the winding drum 15. Under the action of the motor 317, the winding drum 15 rotates and the cable is wound on the winding drum 15 for collection.
