Description

Technical Field

[0001] This invention relates to the field of cable stranding, and more particularly to a braiding arrangement device for multi-core cables. Background Technology

[0002] In the cable production process, multiple conductors need to be twisted into a cable core. During the production process, multiple core wires are twisted into a single cable core by a stranding machine. The stranding machine uses a rotating drum, a core wire guiding mechanism, and a stranding die to twist multiple core wires into a single cable core.

[0003] The structure of a core wire guiding mechanism generally includes a circular guide center plate, on which several guide rollers are evenly distributed around the circumference. Since the number of guide rollers on the guide center plate is fixed, it cannot meet the needs when more core wires are required. To solve the above problem, a larger guide center plate must be used, which requires the manufacture of multiple guide center plates of different sizes to meet production needs, thus increasing production costs. Summary of the Invention

[0004] To improve the applicability of the core wire guiding mechanism, the present invention provides a braiding arrangement device for multi-core cables.

[0005] The present invention provides a braiding arrangement device for multi-core cables, which adopts the following technical solution: A braiding and arranging device for multi-core cables includes a rotating drum, a core wire guiding mechanism, and a stranding die mechanism. The core wire guiding mechanism is located between the rotating drum and the stranding die mechanism and rotates synchronously with the rotating drum. The core wire guiding mechanism includes a first guiding assembly. The first guiding assembly includes an annular guide frame, a plurality of outer conductors, and a plurality of inner conductors. The rotational axes of the guide frame and the rotating drum are collinear. The outer conductors are detachably connected to the outer cylindrical surface of the guide frame, and their positions are adjustable along the outer cylindrical surface of the guide frame. The inner conductors are detachably connected to the inner cylindrical surface of the guide frame, and their positions are adjustable along the inner cylindrical surface of the guide frame. The outer conductors and the inner conductors are used to guide the core wires and are circumferentially offset.

[0006] By adopting the above technical solution, and by setting the guide frame in a circular shape and setting an outer conductor with an adjustable circumferential position on the outer cylindrical surface of the guide frame and an inner conductor with an adjustable circumferential position on the inner cylindrical surface, the expansion capability of the core wire is increased. At the same time, the outer conductor and the inner conductor are detachably mounted on the guide frame, so the outer conductor and the inner conductor can be added or removed as needed to meet the requirements of different numbers of core wires, thus making it highly applicable.

[0007] Optionally, a plurality of external connecting seats are detachably connected to the outer cylindrical surface of the guide frame; the external connecting seats are adjustable along the outer cylindrical surface of the guide frame; the external guide wire is detachably connected to the outer surface of the external connecting seats.

[0008] By adopting the above technical solution, a sufficient number of external connecting seats can be pre-connected on the outer cylindrical surface of the guide frame. Based on this, a corresponding number of external guide wires can be installed on the external connecting seats according to actual needs, thus enhancing the flexibility of the use of external guide wires.

[0009] Optionally, the outer cylindrical surface of the guide frame is formed with a coaxially arranged annular outer connecting ring; the cross-section of the outer connecting ring is T-shaped; the outer connecting seat includes a fan-shaped outer center plate and a pair of fan-shaped outer support plates; the cross-section of the outer support plates is L-shaped; the pair of outer support plates are respectively detachably connected to the two ends of the outer center plate in the axial direction; an arc-shaped outer sliding groove that mates with the outer connecting ring is formed between the pair of outer support plates and the outer center plate; an outer limiting bolt is radially screwed onto the outer center plate from the outside to the inside; the inner end of the outer limiting bolt abuts against the outer cylindrical surface of the outer connecting ring; the outer guide component is connected to the outer connecting seat through the pair of outer limiting bolts.

[0010] By adopting the above technical solution, during installation, a pair of outer support plates and an outer center plate surround the outer connecting ring, and then the pair of outer support plates and an outer center plate are connected as one unit. This makes the installation of the outer connecting seat convenient. By tightening a pair of limit bolts, the inner end of the outer connecting seat can be made to abut against or separate from the outer cylindrical surface of the outer connecting ring, thus achieving the fixation and movement of the outer connecting seat. The structure is simple and the operation is convenient. At the same time, the outer guide wire is also connected by a pair of limit bolts, so no other connection structure is required, and the structure is simple.

[0011] Optionally, a plurality of inner connecting seats are detachably connected to the inner cylindrical surface of the guide frame; the inner connecting seats are adjustable along the inner cylindrical surface of the guide frame; the outer inner guide wire is detachably connected to the inner surface of the inner connecting seats.

[0012] By adopting the above technical solution, a sufficient number of inner connecting seats can be pre-connected on the inner cylindrical surface of the guide frame. Based on this, a corresponding number of inner guide wire components can be installed on the inner connecting seats according to actual needs, thus enhancing the flexibility of the use of the inner guide wire components.

[0013] Optionally, the inner cylindrical surface of the guide frame is formed with a coaxially arranged annular inner connecting ring; the cross-section of the inner connecting ring is T-shaped; the inner connecting seat includes a fan-shaped inner center plate and a pair of fan-shaped inner side support plates; the cross-section of the inner side support plates is L-shaped; the pair of inner side support plates are detachably connected to the two ends of the inner center plate in the axial direction; an arc-shaped inner sliding groove that mates with the inner connecting ring is formed between the pair of inner side support plates and the inner center plate; a pair of inner limiting bolts are screwed onto the inner center plate from the inside to the outside; the outer ends of the inner limiting bolts abut against the inner cylindrical surface of the inner connecting ring; the inner guide component is connected to the inner connecting seat through the pair of inner limiting bolts.

[0014] By adopting the above technical solution, during installation, a pair of inner side support plates and an inner center plate surround the inner connecting ring, and then the pair of inner side support plates and the inner center plate are connected as a whole. In this way, the inner connecting seat is easy to install. By tightening a pair of inner limit bolts, the inner end of the inner connecting seat can be made to abut against the inner cylindrical surface of the inner connecting ring or separate from the inner cylindrical surface of the inner connecting ring, thereby realizing the fixation and movement of the inner connecting seat. The structure is simple and the operation is convenient. At the same time, the inner connecting seat is also connected by a pair of inner limit bolts, so no other connection structure is required, and the structure is simple.

[0015] Optionally, the core wire guiding mechanism further includes a second guiding component; the second guiding component includes a spherical traction ball; the traction ball is located on the rotational central axis of the guide frame; the traction ball is located between the guide frame and the stranding mold mechanism; a plurality of annular traction grooves are formed on the spherical surface of the traction ball; all the traction grooves are evenly distributed around the rotational central axis of the guide frame.

[0016] By adopting the above technical solution, the core wires guided from the outer and inner conductors start from the same circumference. If they directly enter the stranding die mechanism for stranding, it will affect the direction of the core wires and thus affect the quality of subsequent stranding. With the presence of the traction ball, the core wires guided from the outer and inner conductors will pass through the traction groove of the traction ball and reach the stranding die mechanism, so that the starting point of the core wires leaving the traction ball is on the same circumference, which is beneficial to improving the quality of subsequent stranding.

[0017] Optionally, the position of the traction ball along the rotation center axis of the guide frame can be adjusted.

[0018] By adopting the above technical solution, and by adjusting the position of the traction ball on the rotation center axis of the guide frame, the situation where the core wire does not pass through the traction ball due to the position of the traction ball can be avoided.

[0019] Optionally, a cylindrical central connecting tube is formed on the end face of the rotating drum near the stranding mold mechanism; a circular connecting hole is formed on the traction ball; the central axis of rotation of the connecting hole and the guide frame are collinear; a cylindrical telescopic cylinder is inserted into and fixed in the connecting hole; the telescopic cylinder is coaxially sleeved on the central connecting tube; a plurality of circumferentially evenly distributed limiting bolts are radially screwed onto the telescopic cylinder; the inner end of the limiting bolt abuts against the outer cylindrical surface of the central connecting tube.

[0020] By adopting the above technical solution, during adjustment, all the limit bolts are loosened, allowing the telescopic cylinder to move axially on the central connecting pipe. After the traction ball reaches the appropriate position, all the limit bolts are tightened. The mechanism is simple and easy to operate.

[0021] Optionally, the stranding die mechanism includes a stranding base, a die support frame disposed on the stranding base, and a stranding die body disposed on the die support frame; the die support frame is adjustable in position along the rotation center axis of the guide frame.

[0022] By adopting the above technical solution, the tilt angle of the core wire entering the stranding die body can be controlled by controlling the position of the die support frame on the rotation center axis of the guide frame, thereby improving the stranding quality.

[0023] Optionally, the vertical position of the stranding die body on the die support frame is adjustable.

[0024] By adopting the above technical solution, the adjustable vertical position of the stranding die body can be used to correct the center position deviation of the stranding die body, thereby improving the stranding quality.

[0025] In summary, the beneficial effects of the present invention are as follows: 1. Increased core wire expansion capability to meet different core wire requirements, making it highly adaptable.
