[0001] The utility model relates to the technical field of cable processing, and particularly relates to a tubular stranding machine. Background Art

[0002] A tubular stranding machine is used to strand a plurality of insulating materials on the outer wall of a metal wire, and then convey them to an injection molding device to form a tubular outer layer, thereby obtaining a cable.

[0003] When the metal wire is stranded with the insulating material in the stranding machine, the main metal wire will penetrate through the main shaft, and then the main shaft rotates so that the insulating material is wound around the outer wall of the metal wire penetrating through the main shaft, and the inner core of the cable can be obtained.

[0004] Since the metal wire must completely penetrate the main shaft to converge with the insulating material, but the main shaft has been in a working state during the operation of the stranding machine, when the metal wire penetrates the main shaft, the metal wire contacts the inner wall of the rotating main shaft, resulting in a large frictional force and torque force on the metal wire, causing wear of the metal wire, thereby reducing the stranding quality of the cable.

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] The present invention provides a Figures 1-4 shown tube type cabling machine, including a horizontal plate 101 and a wire passing mechanism. A vertical plate 102 is fixedly connected to the top of the horizontal plate 101. A main shaft 103 is rotatably inserted through the front surface of the vertical plate 102. A wire twisting mechanism is arranged on the outer wall of the main shaft 103. The metal wire passes through the main shaft 103 through the wire passing mechanism, and then the insulating material is wound on the outer wall of the metal wire through the wire twisting mechanism. Then the wound metal wire is conveyed into an injection molding device to form a tubular outer layer, and a tubular cable can be obtained.

[0023] Among them, the wire twisting mechanism includes a first turntable 701 fixedly sleeved on the outer wall of the main shaft 103. A plurality of U-shaped frames 702 are fixedly arranged in an annular array on the back surface of the first turntable 701.

A second turntable 705 is fixedly sleeved on the outer wall of the main shaft 103 and located on the back surface of the I-shaped wheel 704. A plurality of connecting holes 706 are opened in an annular array on the front surface of the second turntable 705. The number and position of the connecting holes 706 match the number and position of the I-shaped wheels 704. A driving mechanism is arranged on the outer wall of the main shaft 103. The insulating material to be wound on the outer wall of the metal wire is wound on the outer wall of the I-shaped wheel 704 before use. As the metal wire passes through the wire passing mechanism, the insulating material on the I-shaped wheel 704 will pass through the connecting holes 706, and then as the main shaft 103 rotates to drive the first turntable 701 to rotate, the plurality of I-shaped wheels 704 can revolve around the main shaft 103, so that the insulating material released through the I-shaped wheels 704 will be wound on the outer wall of the metal wire to complete wire twisting.

[0024] Preferably, the driving mechanism includes a second sprocket 603 fixedly sleeved on the outer wall of the main shaft 103.

Through the connection of the connecting collar 301 and the connecting rod 302, and the connecting collar 301 is sleeved on the part of the rotating pipe 202 protruding from the main shaft 103, and through the cooperation of the first fixing mechanism and the second fixing mechanism, the rotating pipe 202 can be fixed without being affected by the main shaft 103, so that the metal wire can stably pass through the rotating pipe 202.

[0027] Further, the first fixing mechanism includes a first jack 401 opened on the outer wall of the connecting collar 301.
